Background

In the data era, data transmission and display are more and more convenient, and data security is also brought, wherein the peep-proof display screen technology can bring great security to users with privacy protection requirements, so that it is very necessary to develop a simple and effective peep-proof display technology.

Existing solutions include:

1. attaching a peep-proof film, attaching the peep-proof film on a display screen to realize peep-proof, and realizing peep-proof by limiting the mode of large-angle contrast and brightness.

2. The peep-proof cell is used and is arranged in a display screen, and peep-proof and wide-view angle switching is realized by controlling the opening and closing of a liquid crystal box of the peep-proof cell.

3. Use peep-proof backlight, there are two sets of backlight sources in the backlight unit of LCD display screen: one is a wide-viewing angle backlight module, the other is a narrow-viewing angle backlight module, and the wide-viewing angle backlight (characterized by high light intensity under a large viewing angle) is turned on under a normal state, and the narrow-viewing angle backlight module is turned off; and in the peep-proof mode, closing the wide-viewing-angle backlight module and opening the narrow-viewing-angle backlight module.

4. An interference electrode is added in the cell to interfere the liquid crystal deflection of the display screen. When the wide visual angle mode is needed, the interference electrode is closed, and when the peep-proof mode is needed, the interference electrode is opened and can influence the liquid crystal deflection, so that light leakage is generated, and the contrast of the display screen under the large visual angle can be interfered to a great extent by the light leakage, so that the peep-proof is realized.

However, the disadvantages of the above solutions are also quite evident, including:

1. the mode of using the pad pasting, the biggest shortcoming is that the pad pasting can bring luminance and contrast to descend, in case attached, is difficult to tear off, so can't switch peep-proof mode and wide visual angle mode in real time.

2. The scheme of using the peep-proof cell firstly increases the weight and the thickness of the whole display screen module, and the peep-proof cell is made of glass, so that the scheme is easier to crack in transportation, assembly and use. Meanwhile, the cost is increased more due to the process duplication of the cell. Meanwhile, the transparency of the cell is poor, which results in a large increase in the power consumption of the module.

3. Use peep-proof backlight scheme, increased a backlight unit, the thickness and the weight increase of product are more.

4. The peep-proof mode of the interference electrode is used, after the interference mode is turned on, normal display can be interfered while display at a large visual angle is influenced, and therefore product experience displayed for a user can be greatly reduced.

As shown in fig. 1 and 2, the present invention provides a privacy film attached to a display screen of an electronic device, the privacy film including:

a plurality of firstunit film groups 4, each firstunit film group 4 including a plurality offirst unit films 6 arranged in a straight line, the plurality of firstunit film groups 4 respectively corresponding to the plurality of odd-numberedpixels 2 in thedisplay screen 1, and eachfirst unit film 6 corresponding to a pixel in one odd-numberedpixel 2;

a plurality of secondunit film groups 5, each secondunit film group 5 including a plurality ofsecond unit films 7 arranged in a straight line, the plurality of secondunit film groups 5 corresponding to the plurality of even-numberedpixels 3 in thedisplay screen 1, respectively, and eachsecond unit film 7 corresponding to a pixel in one even-numberedpixel 3;

thefirst unit film 6 enables light to be normally output, and thesecond unit film 7 enables the light to be gathered so as to limit the output light to be located in a target area in the direction of the front-view display screen 1.

For example, the electronic device may be a mobile device such as a notebook computer and a mobile phone, or may be a device such as a desktop computer, which is not specifically limited. The peep-proof film is attached to a screen of adisplay screen 1 of the electronic equipment. The peep-proof membrane in this embodiment includes a plurality of firstunit membrane groups 4, and a plurality of secondunit membrane groups 5. The plurality of firstunit film groups 4 are arranged to form a plurality of rows, the plurality of secondunit film groups 5 are arranged to form a plurality of rows, and the plurality of firstunit film groups 4 and the plurality of secondunit film groups 5 are sequentially and alternately arranged, namely, one row of firstunit film groups 4 and one row of second unit film groups 5. Each firstunit film group 4 corresponds to an odd-numbered line ofpixels 2 in thedisplay screen 1, each firstunit film group 4 comprises a plurality offirst unit films 6, thefirst unit films 6 are arranged in a straight line shape to form a line and correspond to each pixel in the odd-numbered line ofpixels 2 in thedisplay screen 1 one by one, namely, the shapes, the sizes and the positions of the first unit films are matched and correspond to each other, so that light rays output by the pixels in the odd-numbered line are received and led out by the correspondingfirst unit films 6. Each secondunit film group 5 corresponds to an even-numbered line ofpixels 3 in thedisplay screen 1, each secondunit film group 5 comprises a plurality ofsecond unit films 7, thesecond unit films 7 are arranged in a straight line shape to form a line and correspond to each pixel in the even-numbered line ofpixels 3 in thedisplay screen 1 one by one, namely, the shapes, the sizes and the positions of the second unit films are matched and correspond to each other, such as rectangular frames, so as to ensure that light rays output by the pixels in the even-numbered line are received and led out by the correspondingsecond unit films 7. Of course, in practical applications, the firstunit film group 4 may correspond to thepixels 3 in the even rows, and the secondunit film group 5 may correspond to thepixels 2 in the odd rows, which is basically the same as the above-mentioned solution, so that even if the arrangement positions of the firstunit film group 4 and the secondunit film group 5 relative to thepixels 2 in the odd rows and thepixels 3 in the even rows are changed, the arrangement positions should not be taken as the features limiting the present application. Further, the structure of thefirst unit film 6 in this embodiment belongs to a non-light-condensing structure, which enables light to be output normally, and the structure of thesecond unit film 7 belongs to a light-condensing structure, which is used for converging light to restrict the output light to be located in a target area in the direction of the frontview display screen 1, that is, at this time, a user can only see a displayed image in the direction of the frontview display screen 1, and can not see the displayed image when watching thedisplay screen 1 at other angles, thereby achieving an anti-peeping effect.

Based on above-mentioned embodiment can know, its beneficial effect who possesses includes through setting up the peep-proof membrane into the form that contains a plurality offirst unit membrane 6 and thesecond unit membrane 7 with the oddnumber row pixel 2 ofdisplay screen 1, the evennumber row pixel 3 one-to-one, andfirst unit membrane 6 is the structure that can make light normal output, andsecond unit membrane 7 tails make light gather together to the structure that the light of restriction output is located the target area of looking forwarddisplay screen 1 direction. When a user wants to have a wide-view effect, the working output of the odd-numbered lines ofpixels 2 of thedisplay screen 1 can be controlled through the electronic equipment, so that light can normally pass through the correspondingfirst unit films 6; when a user wants to have a peep-proof effect, the electronic device can control the even-numbered lines ofpixels 3 of thedisplay screen 1 to work and output, so that light is focused in a target area in the direction of looking at thedisplay screen 1, and other users are prevented from peeping the display content of thedisplay screen 1 from the direction which is not looking at thedisplay screen 1. In addition, when a user wants to watch a high-resolution image, all pixels of thedisplay screen 1 can be controlled to work and output through the electronic equipment, so that the user can watch the high-resolution image in the direction of looking at thedisplay screen 1, various watching and using requirements of the user are met, and the power consumption of the equipment cannot be increased. In addition, since the entire privacy film of the present embodiment has a film structure, the thickness is thin, and thus the thickness and weight of thedisplay panel 1 are not increased.

Further, thefirst unit film 6 in this embodiment is made of a transparent film material, such as a polyurethane film, and the light emitted from the corresponding pixel can exit thefirst unit film 6 in the direction shown in fig. 3, and the light path and the intensity of the light are not affected.

Further, a microconvex lens 8 for converging light is provided in thesecond unit film 7 in this embodiment. The light emitted by the corresponding pixel can be gathered and emitted out of thesecond unit film 7 through the microconvex lens 8 along the direction shown in fig. 3, so that the light is emitted in a target area along the direction of the front-view display screen 1, and if the light deviates from the direction and the target area within the visual field range of the front-view display screen 1, the image displayed by thedisplay screen 1 cannot be seen, and the anti-peeping effect is realized.

Further, thesecond unit film 7 in the present embodiment is made of a material capable of attenuating light, such as a filter film made of a filter material, or the like. Thesecond unit film 7 is set in such a form that the light intensity can be weakened in order to weaken the light intensity of the light gathered by the microconvex lens 8, so that the light intensity of the light emitted out of thesecond unit film 7 is almost the same as the light intensity of the light passing through thefirst unit film 6, the visual effect of the user on watching the display content is increased, and the display effect of the picture is ensured while peeping prevention is ensured.

The privacy film in this embodiment is implemented by adjusting the working output of the pixels of thedisplay screen 1 in combination with different effects. For example, when a wide viewing angle effect is implemented, that is, when a plurality of users can view the display content of thedisplay screen 1 at different viewing angles, the odd-numberedline pixels 2 of thedisplay screen 1 need to be adjusted to be displayed, and the even-numberedline pixels 3 do not output. When the peep-proof effect is to be achieved, that is, only the user looking at thedisplay screen 1 can see the display content, the even-numberedpixels 3 of thedisplay screen 1 need to be adjusted to display, that is, the pixels corresponding to the second display film perform the working output, and the odd-numberedpixels 2 do not output. However, if the user wants to see the high-resolution display screen in the front view direction of thedisplay screen 1, all the pixels of thedisplay screen 1 may be controlled to perform the working output to improve the resolution of the screen, but the high-resolution display screen can only be seen in the front view direction of thedisplay screen 1, and only a part of the screen can be seen in the other directions, because the light corresponding to thesecond unit film 7 still has the anti-peeping effect and cannot be seen in the non-front view angle.

Further, another embodiment of the present invention also discloses an electronic device, which includes a display screen, and the privacy film according to any one of the embodiments above attached to the display screen.

The electronic device in this embodiment may be a notebook computer, a desktop computer, or a mobile device such as a mobile phone and a tablet computer.

Further, as shown in fig. 4, another embodiment of the present invention further discloses a display method, which is applied to the electronic device described above, and the method includes:

obtaining a user instruction;

and in response to a user instruction, controlling the odd-row pixels and/or the even-row pixels of the display screen in the electronic equipment to display.

Specifically, obtaining a user instruction includes:

obtaining a user instruction input by a user based on a virtual key of the electronic equipment; or

User instructions input by a user based on physical keys of the electronic device are obtained.

For example, the user instructions include at least 3 different user instructions, including instructions for adjusting the working output of pixels on odd rows of the display screen, instructions for adjusting the working output of pixels on even rows of the display screen, instructions for adjusting the working output of pixels on all rows of the display screen, and so on. In addition, in order to realize accurate input of different user instructions, a software setting interface including a plurality of virtual keys may be provided in the electronic device, for example, the host, and a user may call the setting interface and click different virtual keys to realize input of different user instructions. Or, different entity keys may be arranged on the host or the display of the electronic device, or the electronic device may be a sliding key, and a user may input different user instructions by clicking or sliding the different entity keys to different gear positions.

Specifically, when inputting different user instructions, the electronic device may control the IC of the display to perform different display adjustments, that is, to perform different adjustments on the pixels for work output, and the following describes different embodiments with reference to fig. 5:

the first embodiment is as follows:

the user instruction is a first instruction;

in response to a user instruction, the method for controlling the display screen in the electronic device to display the pixels on the odd lines and/or the pixels on the even lines comprises the following steps:

and responding to the first instruction, controlling odd-numbered pixels of a display screen in the electronic equipment to perform work output, and enabling light rays to be emitted after passing through the corresponding first unit films in the peep-proof film, so that wide-view display is realized.

For example, the first instruction is a wide viewing angle display mode operation instruction, after the electronic device receives the first instruction, the electronic device responds to the first instruction, and controls odd-numbered pixels of a display screen in the electronic device to perform work output, and even-numbered pixels stop work output, at this time, light output by the odd-numbered pixels penetrates through a first unit film corresponding to the first unit film in the peep-proof film and then is emitted, and the first unit film does not influence the direction of a light path, so the light can be emitted to multiple directions, and when the display screen is seen in the light emitting direction, a display picture of the display screen can be seen, and therefore the wide viewing angle display effect is achieved.

Example two:

the user instruction is a second instruction;

in response to a user instruction, controlling odd line pixels and/or even line pixels of a display screen in the electronic device to display, comprising:

and responding to the second instruction, controlling even-numbered pixels of the display screen in the electronic equipment to perform work output, enabling the light to be emitted after passing through the corresponding second unit film in the peep-proof film, and limiting the light in a target area in the direction of the front-view display screen to realize the peep-proof effect.

For example, the second instruction is a peep-proof display mode operation instruction, when the electronic device receives the second instruction, the electronic device responds to the second instruction, and controls the even-numbered pixels of the display screen in the electronic device to perform work output, and the odd-numbered pixels stop work output, at this time, the light output by the even-numbered pixels passes through the corresponding second unit film in the peep-proof film and then is emitted, because the second unit film is internally provided with the micro convex lens, the micro convex lens has a light gathering effect, the light can affect the light path direction, the light is gathered, and the light before and after gathering is attenuated by the light attenuation material of the second unit film, so that the light intensity of the output light is equivalent to the light intensity of the light which is not emitted by the peep-proof film, and the display effect is ensured. Moreover, because the light path emitting direction is changed, at the moment, the light can be output along the direction of the front-view display screen, namely, the light is output in a small range, so that a user can only watch the display content in the direction of the front-view display screen, and the display content cannot be seen in other directions, thereby realizing the peep-proof effect.

Example three:

the user instruction is a third instruction;

in response to a user instruction, the method for controlling the display screen in the electronic device to display the pixels on the odd lines and/or the pixels on the even lines comprises the following steps:

and responding to a third instruction, controlling the odd-row pixels and the even-row pixels of the display screen in the electronic equipment to work and output, and enabling light rays to pass through all the first unit films and all the second unit films in the peep-proof film and then to be emitted out, so that the display of a high-resolution image in the direction of looking at the display screen is realized.

For example, the third instruction is a high resolution display mode operation instruction, and after receiving the third instruction, the electronic device controls the odd-numbered pixels and the even-numbered pixels of the display screen in the electronic device to perform work output in response to the third instruction, at this time, light output by the odd-numbered pixels passes through the corresponding first unit films and is emitted indiscriminately, while light output by the even-numbered pixels passes through the second unit films corresponding to the peep-proof films and is emitted, because the micro convex lenses are arranged in the second unit films, and have a light condensing effect, the light path direction is affected by the micro convex lenses, that is, the light path emission direction is changed, and at this time, the light is output in a small range along the direction of the front view display screen, so that a user can only see high resolution display content in the direction of the front view display screen, and can only see part of the display content in the other directions, and can only see images output by the odd-numbered pixels but cannot see images output by the even-numbered pixels.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
