Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application provides a display device, as shown in fig. 1 and fig. 2, fig. 1 is a schematic top view of the display device, and fig. 2 is an enlarged schematic view of a dashed box in fig. 1, where the display device includes: aframe area 300, afirst display area 100 and asecond display area 200 at least partially surrounding thefirst display area 100, the light transmittance of thefirst display area 100 being greater than the light transmittance of thesecond display area 200.

And a plurality of touch electrodes arranged in thefirst display area 100 and thesecond display area 200, the touch electrodes including afirst touch electrode 21 and asecond touch electrode 31.

The plurality offirst touch electrodes 21 arranged along the first direction DR1 are electrically connected to each other to form afirst electrode group 20, the plurality ofsecond touch electrodes 31 arranged along the second direction DR2 are electrically connected to each other to form asecond electrode group 30, a length of the display device along the first direction DR1 is smaller than a length of the display panel along the second direction DR2, and the second direction DR2 intersects with the first direction DR 1.

Thetouch circuit 10 is located in theframe area 300.

Thetouch circuit 10 is configured to provide a touch emission signal to thefirst electrode set 20, and the intensity of the touch emission signal provided to the first electrode set 20 overlapped with thefirst display area 100 is greater than the intensity of the touch emission signals provided to the otherfirst electrode sets 20.

And/or

Thetouch circuit 10 is further configured to amplify a touch sensing signal fed back by at least a portion of thesecond touch electrode 31 located in thefirst display area 100.

In the display device, in order to ensure the normal operation requirement of the optical elements (such as a camera, an optical sensor, a structural light emitting device, and the like) disposed on the side of thefirst display area 100 away from the display direction of the display device, the light transmittance of thefirst display area 100 generally needs to be designed to be larger, in order to meet the light transmittance requirement of thefirst display area 100, thefirst touch electrode 21 and thesecond touch electrode 31 arranged in thefirst display area 100 need to be specially designed, the special designs include reducing the number of thefirst touch electrode 21 and thesecond touch electrode 31 arranged in thefirst display area 100 or reducing the effective electrode area, and the like, when the number of thefirst touch electrode 21 and thesecond touch electrode 31 arranged in thefirst display area 100 is reduced, the number of touch capacitors (formed by thefirst touch electrode 21 and thesecond touch electrode 31 in a mutual capacitance manner) in a unit area in thefirst display area 100 is reduced, therefore, the intensity of the touch sensing signal fed back by thesecond touch electrode 31 in thefirst display area 100 is lower than the touch sensing signal fed back by thesecond touch electrode 31 in thesecond display area 200 under the same touch area of the operating body, which results in poor touch sensitivity in thefirst display area 100.

As can be seen from the capacitance calculation formula C ═ S/4 π kd, under the condition that the electrostatic force constant k, the distance d between the two electrodes, and the dielectric permittivity ∈ are not changed, the size of the capacitance C is positively correlated with the effective areas S of the two electrodes, so that if the effective electrode areas of thefirst touch electrode 21 and thesecond touch electrode 31 arranged in thefirst display area 100 are reduced, the intensity of the touch sensing signal fed back by thesecond touch electrode 31 in thefirst display area 100 is smaller than the intensity of the touch sensing signal fed back by thesecond touch electrode 31 in thesecond display area 200 under the same touch area of the operating body, which results in poor touch sensitivity in thefirst display area 100.

In the conventional display device design, the touch emission signal provided for a certain row of touch electrodes cannot be adjusted individually, which makes the problem difficult to solve.

In the display panel provided in the embodiment of the present application, thetouch circuit 10 provides the touch emission signal to thefirst electrode group 20 extending along the first direction DR1 (i.e. the short side extending direction of the display device), so that the touch emission signal provided by thefirst electrode group 20 in a single row or several rows can be adjusted, the adjustment does not affect the touch electrodes of thesecond display area 200 located at two sides of the second direction DR2 of thefirst display area 100, and the touch emission signal of thefirst display area 100 of the display device can be adjusted accordingly.

After the intensity of the touch emission signal provided to thefirst electrode group 20 overlapped with thefirst display area 100 is properly increased, the capacitance value of the touch capacitor formed between thefirst electrode group 20 and thesecond electrode group 30 in a mutual capacitance manner is correspondingly increased, the capacitance change caused when the operating body touches the area is correspondingly increased, and the value of the touch sensing signal received by thetouch circuit 10 is correspondingly increased, so as to achieve the purpose of improving the touch sensitivity of thefirst display area 100.

In addition, thetouch circuit 10 can also directly achieve the purpose of increasing the touch sensing signal in thefirst display area 100 by amplifying the touch sensing signal fed back by at least part of thesecond touch electrode 31 located in thefirst display area 100.

Thetouch circuit 10 "provides the intensity of the touch emission signal for thefirst electrode group 20 overlapped with thefirst display area 100 to be greater than the intensity of the touch emission signal provided for the otherfirst electrode groups 20", and the two ways of amplifying the touch sensing signal fed back by thesecond touch electrode 31 at least partially located in thefirst display area 100 to increase the touch sensing signal fed back by thesecond touch electrode 31 may be only one of the two ways, that is, in some embodiments of the present application, the touch sensing signal fed back by thesecond touch electrode 31 may be increased only by "the strength of the touch emission signal provided to thefirst electrode group 20 overlapped with thefirst display area 100 is greater than the strength of the touch emission signals provided to the otherfirst electrode groups 20", or the touch sensing signal fed back by thesecond touch electrode 31 may be increased only by "the touch sensing signal fed back by thesecond touch electrode 31 located at least partially in thefirst display area 100 is amplified".

However, in other embodiments of the present application, two ways may be adopted to jointly achieve the purpose of increasing the touch sensing signal fed back by thesecond touch electrode 31, that is, increasing the touch emitting signal provided to thefirst electrode group 20 overlapped with thefirst display area 100 and amplifying thesecond touch electrode 31 at least partially located in thefirst display area 100, which is not limited in this application, and is determined according to the actual situation.

On the basis of the above embodiments, in an embodiment of the present application, as shown in fig. 3, fig. 3 is a schematic top view structure diagram of a display device, where the first touch electrode includes afirst type electrode 211, asecond type electrode 212, and athird type electrode 213;

thefirst type electrodes 211 are distributed in thefirst display area 100, thesecond type electrodes 212 are distributed in thesecond display area 200, thethird type electrodes 213 are partially positioned in thefirst display area 100, and the other part is positioned in thesecond display area 200;

the touch control circuit is used for providing a first touch control emission signal, a second touch control emission signal and a third touch control emission signal, wherein the intensity of the first touch control emission signal is greater than that of the second touch control emission signal, and the intensity of the second touch control emission signal is greater than that of the third touch control emission signal;

the first touch emission signal is provided to the first electrode group including the first type ofelectrodes 211 and extending in a direction passing through thefirst display area 100, the second touch emission signal is provided to the first electrode group including the third type ofelectrodes 213 and extending in a direction passing through thefirst display area 100, and the third touch emission signal is provided to the first electrode group including the second type ofelectrodes 212 and not overlapping with thefirst display area 100.

In this embodiment, the first touch electrode is further divided into three types of electrodes, and the intensity of the touch emission signal provided to the first electrode group including the three types of electrodes is further refined for the positions of the three types of electrodes. Specifically, for a first electrode group including the first type ofelectrodes 211 and extending in a direction passing through thefirst display area 100, since the first type ofelectrodes 211 are all located in thefirst display area 100, the intensity of the touch emission signal required to be compensated for is the greatest, and therefore the intensity of the first touch emission signal provided for the first type of electrode group is the greatest.

And for the first electrode group including the third type ofelectrodes 213, and extending in a direction passing through thefirst display area 100, since the third type ofelectrodes 213 are partially located in thefirst display area 100 and partially located in thesecond display area 200, the intensity of the touch emission signal to be compensated is weaker than that of the first electrode group including the first type ofelectrodes 211 and extending in a direction passing through thefirst display area 100, compared with the first electrode group including the second type ofelectrode 212 and not overlapping with thefirst display area 100, the strength is stronger, therefore, the intensity of the second touch emission signal is between the first touch emission signal and the third touch emission signal, therefore, the touch sensitivity inside thefirst display area 100, the boundary position between thefirst display area 100 and thesecond display area 200, and the touch sensitivity inside thesecond display area 200 are similar or identical, and the touch experience of the user on the display device is improved.

Still referring to fig. 3, in fig. 3, the first-type electrodes 211, the second-type electrodes 212, and the third-type electrodes 213 are all grid-shaped electrodes, which can improve the transmittance of the touch electrodes in thefirst display area 100 and improve the diffraction effect of the touch electrodes in thefirst display area 100 on light by adjusting the size of the internal grid of the grid-shaped electrodes.

Each first touch electrode comprises a first conductive grid, and the first conductive grid comprises a plurality of first conductive lines.

The first type ofelectrodes 211 comprises a first conductive line having a total surface area that is smaller than a total surface area of the first conductive line comprised by the third type ofelectrodes 213, and the third type ofelectrodes 213 comprises a first conductive line having a total surface area that is smaller than a total surface area of the first conductive line comprised by the second type ofelectrodes 212.

The first conductive line is generally a metal conductive line, a specific electrode pattern can be formed through an etching process of a whole metal, and the first conductive line can also be a conductive film routing line, which is not limited in the present application.

Generally, the overall size of the first conductive grids of each type of first touch electrode is the same, referring to fig. 4, fig. 4 is an enlarged schematic top view of the first touch electrode, in fig. 4, the second type ofelectrodes 212 are taken as an example for illustration, the first conductive wires forming each first touch electrode are not overlapped with thedisplay pixels 40 of the display device, so as to avoid the shielding and absorption of the first conductive wires to the emergent light of thedisplay pixels 40, because thesecond display area 200 does not have a high light transmittance requirement and does not have a need to reduce the light diffraction, in the first conductive grids of the second type ofelectrodes 212, each grid surrounds onedisplay pixel 40, and in thefirst display area 100, because on one hand, the diffraction effect of the first conductive grids to the light needs to be avoided, and on the other hand, the high light transmittance requirement of thefirst display area 100 needs to be met, therefore, the grids of the first type ofelectrodes 211 and the third type ofelectrodes 213 located in thefirst display area 100 are all arranged around a plurality ofdisplay pixels 40, the arrangement density of the first conductive wires is reduced, so that the grid size in the first conductive grid is increased, and the requirements of high transmittance and diffraction reduction are met.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating the intensity relationship among the first touch transmission signal, the second touch transmission signal and the third touch transmission signal, and the intensity relationship among the first touch transmission signal, the second touch transmission signal and the third touch transmission signal may be set according to the total area of the first conductive lines of the first-type electrodes 211, the second-type electrodes 212 and the third-type electrodes 213.

Specifically, the ratio of the intensity of the first touch emission signal to the intensity of the second touch emission signal is equal to the area ratio of the first conductive line of the third-type electrode 213 to the first conductive line of the first-type electrode 211.

The ratio of the intensity of the second touch transmission signal to the intensity of the third touch transmission signal is equal to the ratio of the areas of the first conductive lines of thesecond type electrodes 212 to the first conductive lines of thethird type electrodes 213.

The area ratio of the first conductive line of thethird type electrode 213 to the first conductive line of thefirst type electrode 211 represents the ratio of the effective area of thethird type electrode 213 as a capacitor plate to the effective area of thefirst type electrode 211 as a capacitor plate, and as mentioned above, the capacitance value of the touch capacitor is proportional to the effective area of the capacitor plate, so that the difference in touch sensitivity caused by the difference in effective areas of thefirst type electrode 211 and thethird type electrode 213 can be effectively compensated by setting the ratio of the intensity of the first touch transmitting signal to the intensity of the second touch transmitting signal to the area ratio of the first conductive line of thethird type electrode 213 to the first conductive line of thefirst type electrode 211.

Similarly, the ratio of the intensity of the second touch transmission signal to the intensity of the third touch transmission signal is set as the ratio of the areas of the first conductive line of thesecond type electrode 212 and the first conductive line of thethird type electrode 213, so that the touch sensitivity difference caused by the difference between the effective areas of thethird type electrode 213 and thesecond type electrode 212 can be effectively compensated, and the touch sensitivities of the positions of thefirst type electrode 211, thesecond type electrode 212 and thethird type electrode 213 are similar or identical.

For the second touch electrode, referring to fig. 6, fig. 6 shows a schematic top view structure diagram of the display device, and the second touch electrode includes: afourth type electrode 311, afifth type electrode 313 and asixth type electrode 312;

thefourth type electrodes 311 are distributed in thefirst display area 100, thefifth type electrodes 313 are distributed in thesecond display area 200, and thesixth type electrodes 312 are partially located in thefirst display area 100, and the other part is located in thesecond display area 200.

Thefourth type electrodes 311 are distributed in thefirst display area 100, thefifth type electrodes 313 are distributed in thesecond display area 200, thesixth type electrodes 312 are partially located in thefirst display area 100, and the other part is located in thesecond display area 200;

the amplification factor of the touch sensing signal fed back by the touch circuit for the fourth type ofelectrodes 311 is greater than that of the touch sensing signal fed back by the sixth type ofelectrodes 312, and the amplification factor of the touch sensing signal fed back by the touch circuit for the sixth type ofelectrodes 312 is greater than that of the touch sensing signal fed back by the fifth type ofelectrodes 313.

In this embodiment, the second touch electrode is further divided into three types of electrodes, and the amplification factor of the touch sensing signal of the second electrode group including the three types of electrodes is further refined for the positions of the three types of electrodes. Specifically, for the fourth type ofelectrodes 311, the intensity of the touch sensing signal fed back by the fourth type ofelectrodes 311 is the weakest, and therefore, the amplification factor needs to be allocated to the fourth type of electrodes, while for the sixth type ofelectrodes 312, the intensity of the touch sensing signal fed back by the sixth type ofelectrodes 312 is slightly stronger, and therefore, the amplification factor needs to be allocated to the sixth type of electrodes, and for the fifth type ofelectrodes 313, the intensity of the touch sensing signal fed back by the fifth type of electrodes is the strongest, and the amplification factor allocated to the fifth type of electrodes is the smallest, so that the magnitudes of the touch sensitivities at the boundary position between thefirst display area 100 and thesecond display area 200 and inside thesecond display area 200 inside thefirst display area 100 are similar or identical, thereby improving the touch experience of the user for the display device.

In addition, it should be noted that, referring to fig. 7, fig. 7 shows a schematic diagram during touch scanning, in fig. 7, the manner of providing the touch transmission signal by the touch circuit to the first touch electrode group is a progressive scanning manner, that is, after the touch transmission signal is provided to the first electrode group in the first row, the touch transmission signal is provided to the first electrode group in the second row (i.e., the shaded first electrode group in fig. 7), which results in that although the touch circuit receives the touch sensing signals fed back by all the second touch electrodes on the second electrode group at the same time, for one second electrode group, the touch sensing signal fed back by the second electrode group received at a certain time is mainly fed back by the second touch electrode adjacent to the first electrode group receiving the touch transmission signal (i.e., the second touch electrode identified by the grid pattern in fig. 7), therefore, the touch circuit may be able to feed back the second touch electrode adjacent to the first touch electrode receiving the touch transmission signal according to the current time The touch position of the operation body is determined by the size of the touch sensing signal fed back by the control electrode.

That is, in this embodiment, the touch sensing signal fed back by the second electrode group at a certain time may be considered as a touch sensing signal fed back by a second touch electrode adjacent to the first electrode group receiving the touch emission signal in the second electrode group.

Still referring to fig. 6, in fig. 6, thefourth type electrode 311, thefifth type electrode 313 and thesixth type electrode 312 are all grid electrodes, and the grid electrodes can improve the transmittance of the touch electrodes in thefirst display area 100 on one hand, and can improve the diffraction effect of the touch electrodes in thefirst display area 100 on light by adjusting the size of the internal grid of the grid electrodes.

I.e. each sixth type ofelectrode 312 comprises a second conductive grid comprising a plurality of second conductive lines.

The fourth type ofelectrodes 311 comprises a second conductive line having a total surface area that is smaller than the total surface area of the second conductive line comprised by the sixth type ofelectrodes 312, and the sixth type ofelectrodes 312 comprises a second conductive line having a total surface area that is smaller than the total surface area of the second conductive line comprised by the fifth type ofelectrodes 313.

The second conductive line is generally a metal conductive line, a specific electrode pattern can be formed through an etching process of a whole metal, and the second conductive line can also be a conductive film routing, which is not limited in the present application.

Similar to the first touch electrode, the overall size of the second conductive grids of each type of second touch electrode is the same, the second conductive wires forming each second touch electrode are not overlapped with the display pixels, so as to avoid the shielding and absorption of the second conductive wires to the emergent light of the display pixels, and because thesecond display area 200 does not have the requirement of high light transmittance and the necessity of reducing the light diffraction, each grid surrounds one display pixel in the second conductive grids of the fifth type ofelectrode 313, and in thefirst display area 100, because the diffraction effect of the first conductive grid on the light needs to be avoided on one hand and the high transmittance requirement of thefirst display area 100 needs to be met on the other hand, therefore, the grids of the fourth type ofelectrode 311 and the sixth type ofelectrode 312 in thefirst display area 100 are all arranged around a plurality of display pixels, so as to reduce the arrangement density of the second conductive wires, thereby increasing the grid size in the second conductive grids, meets the requirements of high transmittance and diffraction reduction.

Accordingly, specific amplification factors of the touch circuit for thefourth type electrode 311, thefifth type electrode 313 and thesixth type electrode 312 can be set as follows:

the ratio of the amplification factor of the touch circuit for the touch sensing signal fed back by the fourth type ofelectrode 311 to the amplification factor of the touch circuit for the touch sensing signal fed back by the sixth type of electrode is equal to the area ratio of the second conductive line of the sixth type ofelectrode 312 to the second conductive line of the fourth type ofelectrode 311;

the ratio of the amplification factor of the touch sensing signal fed back by the touch circuit for the sixth type ofelectrodes 312 to the amplification factor of the touch sensing signal fed back by the touch circuit for the fifth type ofelectrodes 313 is equal to the area ratio of the second conductive line of the fifth type ofelectrodes 313 to the second conductive line of the sixth type ofelectrodes 312.

The area ratio of the second conductive line of the sixth type ofelectrodes 312 to the second conductive line of the fourth type ofelectrodes 311 represents the ratio of the effective area of the sixth type ofelectrodes 312 as the capacitor plate to the effective area of the fourth type ofelectrodes 311 as the capacitor plate, and the capacitance value of the touch capacitor is proportional to the effective area of the capacitor plate as described above, so that the difference in touch sensitivity caused by the difference in the effective areas of the sixth type ofelectrodes 312 and the fourth type ofelectrodes 311 can be effectively compensated by making the ratio of the amplification factor of the touch sensing signal fed back to the fourth type ofelectrodes 311 to the amplification factor of the touch sensing signal fed back by the touch circuit to the sixth type of electrodes equal to the ratio of the second conductive line of the sixth type ofelectrodes 312 to the second conductive line of the fourth type ofelectrodes 311.

Similarly, the ratio of the amplification factor of the touch sensing signal fed back by the touch circuit to the sixth type ofelectrodes 312 to the amplification factor of the touch sensing signal fed back by the touch circuit to the fifth type ofelectrodes 313 is equal to the ratio of the areas of the second conductive lines of the fifth type ofelectrodes 313 to the second conductive lines of the sixth type ofelectrodes 312, so that the difference in touch sensitivity caused by the difference in effective areas of the sixth type ofelectrodes 312 and the fifth type ofelectrodes 313 can be effectively compensated, and the touch sensitivities of the positions of the fourth type ofelectrodes 311, the fifth type ofelectrodes 313 and the sixth type ofelectrodes 312 are similar or identical.

Optionally, as described above, to avoid the problem of shielding the emergent light of the display pixels by the first touch electrode and the second touch electrode, for the plurality of display pixels arranged in thefirst display area 100, the orthographic projection of the touch electrode in thefirst display area 100 and the orthographic projection of the display pixel in thefirst display area 100 are not overlapped with each other. The touch electrodes are formed by the conductive wires, the conductive wires are arranged in gaps among the display pixels, the problem that the conductive wires shield emergent rays of the display pixels is solved, meanwhile, the touch electrodes can be shielded by utilizing a black matrix of a color film substrate in the display device, and the problem that the touch electrodes reflect rays to cause display is solved.

On the basis of the above embodiments, in an alternative embodiment of the present application, as shown in fig. 8, fig. 8 shows a schematic top view structure diagram of a display device, and thesecond display area 200 further includes: at least onethird display area 400.

The extending direction of thethird display area 400 is a first direction, and at least one side of thethird display area 400 is adjacent to the edge of thefirst display area 100.

The display panel further includes: a plurality ofdummy electrodes 50.

Thedummy electrodes 50 are distributed in thethird display area 400.

In fig. 8, only a portion of thesecond display area 200 and a portion of the touch electrode are shown for clarity of illustration.

In the present embodiment, the effective area of the touch electrode in thethird display area 400 is the same as the effective area of the touch electrode in thesecond display area 200. However, when the strength of the touch emission signal provided by the touch circuit for the first electrode group overlapped with thefirst display area 100 is greater, the first electrode groups also pass through thethird display area 400 at the same time, which results in a higher touch sensitivity of thethird display area 400 compared with thefirst display area 100 or othersecond display areas 200, in order to make the touch sensitivity of thethird display area 400 and thefirst display area 100 and othersecond display areas 200 similar or identical, the embodiment of the present application provides somedummy electrodes 50 in thethird display area 400, and thedummy electrodes 50 are not electrically connected with the touch circuit, so as to reduce the effective area of the capacitive plate serving as the touch capacitor in thethird display area 400, thereby achieving the above-mentioned purpose.

On the basis of the above embodiments, in another embodiment of the present application, as shown in fig. 9, fig. 9 is a schematic top view structure diagram of a display device, and in this embodiment, the number of thefirst display regions 100 is greater than or equal to 2.

The number of thefirst display areas 100 is determined according to actual needs, and when the number of the optical elements to be disposed is one, the number of thefirst display areas 100 may be 1, and when the number of the optical elements is two or more, the number of thefirst display areas 100 may also be two or more.
