具光感測功能之顯示裝置及其光感測方法Display device with light sensing function and light sensing method thereof

本發明係關於一種顯示裝置及其方法，特別是一種具光感測功能之顯示裝置，以及顯示裝置的光感測方法。The present invention relates to a display device and a method thereof, in particular to a display device with a light sensing function and a light sensing method of the display device.

隨著科技的演進，顯示影像的各類型顯示裝置的需求亦跟著增加。近來，各種類型的顯示裝置已被廣泛使用，例如液晶顯示（liquid crystal display，LCD）裝置、電漿顯示面板（plasma display panel，PDP）裝置及有機發光顯示（organic light-emitting display，OLED）裝置、量子點發光顯示（quantum dot light-emitting display，QLED）裝置。With the advancement of technology, the demand for various types of display devices for displaying images has also increased. Recently, various types of display devices have been widely used, such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, organic light-emitting display (OLED) devices, and quantum dot light-emitting display (QLED) devices.

由於，傳統顯示裝置並未能讓使用者看到顯示裝置背後之人、事、物等，遂有業者發展出一種透明顯示器(transparent display)，其特色在於裝置本身具有一定程度的穿透性，因此，當該透明顯示器顯示影像時，該透明顯示器還能讓使用者看到位於透明顯示器之背後，也就是相對於使用者另一側的人、事、物等。Since traditional display devices cannot allow users to see the people, things, and objects behind the display devices, some industry insiders have developed a transparent display whose feature is that the device itself has a certain degree of transparency. Therefore, when the transparent display displays an image, the transparent display can also allow the user to see the people, things, and objects behind the transparent display, that is, the other side of the user.

基於該透明顯示器的透明特性，該透明顯示器被廣泛地應用於各種不同的應用場域中，例如:建築物窗戶、汽車車窗、汽車後照鏡或商店櫥窗等。Based on the transparent characteristics of the transparent display, the transparent display is widely used in various application fields, such as: building windows, car windows, car rearview mirrors or store windows, etc.

然而，現有透明顯示器為透過背側邊框或面板上或面板側邊之非透明區上，單獨設置影像擷取裝置或鏡頭，因而導致非透明區之面積增加，使得透明顯示器上透明區之占比下降，如此也讓現有透明顯示器無法設置多元化之光感測器布局，以實現多元智慧人機互動體驗。However, conventional transparent displays are provided with image capture devices or lenses on the back frame or on the non-transparent area on the panel or on the side of the panel, which increases the area of the non-transparent area and reduces the proportion of the transparent area on the transparent display. This also makes it impossible to provide a diversified light sensor layout for the conventional transparent display to realize a diversified intelligent human-computer interaction experience.

再者，現有透明顯示器因未具有亮度補償機制，容易有顯示亮度過高，而導致透明顯示器之背後被強光遮蔽，同時，也使得該透明顯示器於顯示影像之顯示對比度降低。Furthermore, the existing transparent display has no brightness compensation mechanism, so the display brightness is easily too high, resulting in the back of the transparent display being blocked by strong light. At the same time, the display contrast of the transparent display in the displayed image is reduced.

又，習知的透明顯示器若僅單純透明顯示，而未具備透明度之調整機制，較難新增應用的環境，例如:商店櫥窗、會議室透明牆。Furthermore, if the conventional transparent display only displays transparently but does not have a transparency adjustment mechanism, it is difficult to add new application environments, such as store windows and transparent walls in conference rooms.

鑑於上述之問題，本發明提供一種具光感測功能之顯示裝置及其光感測方法，其透過在每一畫素上設置一光感測元件，以直接偵測入射光或經一電致變色液晶面板反射該入射光至該該光感測元件，以感測該入射光，或感測通過一發光模組之該入射光，藉此，避免透明區之占比下降、增加顯示裝置之自動調光效果，並進一步提升該透明顯示器於顯示影像之顯示對比度。In view of the above problems, the present invention provides a display device with a light sensing function and a light sensing method thereof, which sets a light sensing element on each pixel to directly detect the incident light or reflect the incident light to the light sensing element through an electrochromic liquid crystal panel to sense the incident light, or sense the incident light passing through a light-emitting module, thereby avoiding a decrease in the proportion of the transparent area, increasing the automatic dimming effect of the display device, and further improving the display contrast of the transparent display in displaying images.

其中，該些個第一閘極驅動線GL1與該些個第一資料驅動線DL1為耦接該些個感測控制元件1222，例如:該第一感測控制元件122、該第二感測控制元件124與該第三感測控制元件126；該些個第二閘極驅動線GL2與該些個第二資料驅動線DL2耦接該些個顯示控制元件1222A，例如:該第一顯示控制元件122A、該第二顯示控制元件124A與該第三顯示控制元件126A；該些個第三閘極驅動線GL3與該些個第三資料驅動線DL3耦接該些個發光控制元件1222B，例如:該第一發光控制元件122B、該第二發光控制元件124B與該第三發光控制元件126B。如此，相當於將本發明之光感測元件之驅動功能整合至顯示裝置10之驅動電路中。該控制處理電路17耦接該些個光感測元件1222與該資料驅動電路19，以依據該些個光感測元件1222之複數個感測訊號SS產生一控制訊號CON至該資料驅動電路19，以調整該發光模組16之該些個顯示光(例如:該第一顯示光L1、該第二顯示光L2與該第三顯示光L3)的亮度，而驅使該些個畫素101之一亮度改變。Among them, the first gate drive lines GL1 and the first data drive lines DL1 are coupled to thesensing control elements 1222, for example: the firstsensing control element 122, the secondsensing control element 124 and the thirdsensing control element 126; the second gate drive lines GL2 and the second data drive lines DL2 are coupled to thedisplay control elements 1222A, for example: the firstdisplay control element 122A, the seconddisplay control element 124A and the thirddisplay control element 126A; the third gate drive lines GL3 and the third data drive lines DL3 are coupled to the light-emittingcontrol elements 1222B, for example: the first light-emittingcontrol element 122B, the second light-emittingcontrol element 124B and the third light-emittingcontrol element 126B.

請一併參閱第3B圖與第3C圖，透過該閘極驅動電路18與該資料驅動電路19之同步控制，可經由該些個第二閘極驅動線GL2與該些個第二資料驅動線DL2以及該些個第三閘極驅動線GL3與該些個第三資料驅動線DL3同步控制該些個顯示控制元件1222A與該些個發光控制元件1222B(例如:同步驅使該電致變色液晶面板14呈一非透光狀態與驅使該發光模組16提高亮度)。Please refer to Figure 3B and Figure 3C together. Through the synchronous control of thegate drive circuit 18 and the data drivecircuit 19, thedisplay control elements 1222A and the light-emittingcontrol elements 1222B can be synchronously controlled via the second gate drive lines GL2 and the second data drive lines DL2 and the third gate drive lines GL3 and the third data drive lines DL3 (for example: synchronously driving the electrochromicliquid crystal panel 14 to a non-light-transmitting state and driving the light-emittingmodule 16 to increase the brightness).

此外，更可經由該些個第一閘極驅動線GL1與該些個第一資料驅動線DL1以及該些個第二閘極驅動線GL2與該些個第二資料驅動線DL2同步控制該些個感測控制元件1222與該些個顯示控制元件1222A(例如:同步驅使光感測元件感測入射光與驅使該電致變色液晶面板14呈該非透光狀態)，甚至是同步控制該些個感測控制元件1222、該些個顯示控制元件1222A與該些個發光控制元件1222B(例如:同步驅使光感測元件感測入射光、驅使該電致變色液晶面板14呈一透光狀態與驅使該發光模組16降低亮度)。In addition, thesensing control elements 1222 and thedisplay control elements 1222A can be synchronously controlled via the first gate drive lines GL1 and the first data drive lines DL1 as well as the second gate drive lines GL2 and the second data drive lines DL2 (for example, synchronously driving the light sensing element to sense incident light and driving the electrochromicliquid crystal panel 14 to be in the non-light-transmitting state), or even synchronously controlling thesensing control elements 1222, thedisplay control elements 1222A and the light-emittingcontrol elements 1222B (for example, synchronously driving the light sensing element to sense incident light, driving the electrochromicliquid crystal panel 14 to be in a light-transmitting state and driving the light-emittingmodule 16 to reduce the brightness).

以下針對本發明之光感測元件、該電致變色液晶面板14與該發光模組16之控制進行詳細說明。The following is a detailed description of the control of the light sensing element, the electrochromicliquid crystal panel 14 and thelight emitting module 16 of the present invention.

如第3D圖所示，本實施例係以該第一光感測元件111與該第三光感測元件113作為背側照射(BSI)型光感測元件之舉例，並以該第二光感測元件112作為前側照射(FSI)型光感測元件之舉例，但本發明不限於此，更可為該些個光感測元件皆設置呈背側照射(BSI)型光感測元件或前側照射(FSI)型光感測元件。當該第一顯示控制元件122A至該第三顯示控制元件126A控制該第一電壓差V1至該第三電壓差V3，而驅使該電致變色液晶層146呈該非透光狀態時，該非透光狀態之該電致變色液晶層146相當於一鏡面，因而讓一第一入射光IN1與一第三入射光IN3分別反射至該第一光感測元件111與該第三光感測元件113，因本實施例之該第一光感測元件111與該第三光感測元件113作為背側照射(BSI)型光感測元件，因而感測被反射之該第一入射光IN1與該第二入射光IN3。As shown in FIG. 3D , this embodiment uses the firstphotosensitive element 111 and the thirdphotosensitive element 113 as examples of back side illumination (BSI) type photosensitive elements, and uses the secondphotosensitive element 112 as an example of front side illumination (FSI) type photosensitive element, but the present invention is not limited to this, and the photosensitive elements can all be configured as back side illumination (BSI) type photosensitive elements or front side illumination (FSI) type photosensitive elements. When the firstdisplay control element 122A to the thirddisplay control element 126A control the first voltage difference V1 to the third voltage difference V3 and drive the electrochromicliquid crystal layer 146 to the non-light-transmitting state, the electrochromicliquid crystal layer 146 in the non-light-transmitting state is equivalent to a mirror, thereby allowing a first incident light IN1 and a third incident light IN3 to be reflected to the firstlight sensing element 111 and the thirdlight sensing element 113 respectively. Since the firstlight sensing element 111 and the thirdlight sensing element 113 of the present embodiment serve as back-side illumination (BSI) type light sensing elements, the reflected first incident light IN1 and the second incident light IN3 are sensed.

而，本實施例之該第二光感測元件112為前側照射(FSI)型光感測元件，即可直接感測一第二入射光IN2，也就是該第二入射光IN2不須經由該非透光狀態之該電致變色液晶層146之反射即可進行感測。However, the secondlight sensing element 112 of the present embodiment is a front side illumination (FSI) type light sensing element, which can directly sense a second incident light IN2, that is, the second incident light IN2 can be sensed without being reflected by the electrochromicliquid crystal layer 146 in the non-light-transmitting state.

進一步地，如第3E圖所示，本發明更可在背側照射(BSI)型光感測元件設置一濾光層，本實施例係以該第一光感測元件111與該第三光感測元件113設置一第一濾光層1111與一第二濾光層1131作為舉例，因此透過該第一濾光層1111與該第二濾光層1131可讓該第一光感測元件111與該第三光感測元件113感測該第一入射光IN1與該第二入射光IN3之一特定波段或一特定波長，例如:550nm至560nm或者是556nm，或者是紅外光或紫外光，即大於720nm或小於400nm之光線。Furthermore, as shown in FIG. 3E , the present invention may further provide a filter layer on a back side illumination (BSI) type photosensitive element. In this embodiment, afirst filter layer 1111 and asecond filter layer 1131 are provided on the firstphotosensitive element 111 and the thirdphotosensitive element 113 as an example. Thus, through thefirst filter layer 1111 and thesecond filter layer 1131, the firstphotosensitive element 111 and the thirdphotosensitive element 113 may sense a specific band or a specific wavelength of the first incident light IN1 and the second incident light IN3, for example: 550nm to 560nm or 556nm, or infrared light or ultraviolet light, i.e., light greater than 720nm or less than 400nm.

相對應地，該第一顯示控制元件2441控制該第一透明電極2441A與該共用電極層248之間的一第一電壓差VR1，該第二顯示控制元件2442控制該第二透明電極2442A與該共用電極層248之間的一第二電壓差VG1，該第三顯示控制元件2443控制該第三透明電極2443A與該共用電極層248之間的一第三電壓差VB1，該第四顯示控制元件2444控制該第四透明電極2444A與該共用電極層248之間的一第四電壓差VR2，該第五顯示控制元件2445控制該第五透明電極2445A與該共用電極層248之間的一第五電壓差VG2，也就是同於前一實施例，該些個顯示控制元件控制該些個透明電極與該共用電極層之該些個電壓差，以控制該電致變色液晶層246呈該非透光狀態或該透光狀態。Correspondingly, the firstdisplay control element 2441 controls a first voltage difference VR1 between the firsttransparent electrode 2441A and thecommon electrode layer 248, the seconddisplay control element 2442 controls a second voltage difference VG1 between the secondtransparent electrode 2442A and thecommon electrode layer 248, the thirddisplay control element 2443 controls a third voltage difference VB1 between the thirdtransparent electrode 2443A and thecommon electrode layer 248, and the fourthdisplay control element 2444 controls a third voltage difference VB1 between the thirdtransparent electrode 2443A and thecommon electrode layer 248.

That is, the same as the previous embodiment, the display control elements control the voltage differences between the transparent electrodes and the common electrode layer to control the electrochromicliquid crystal layer 246 to be in the non-light-transmitting state or the light-transmitting state.

如第7C圖所示，本實施例之該第一光感測元件211與該第二光感測元件212為不同類型之光感測元件，即該背側照射(BSI)型光感測元件與該前側照射(FSI)型光感測元件，在發光元件不發光時，也就是在第一發光元件262R至該第五發光元件264G不發光時，該電致變色液晶面板24呈一透光狀態，亦即該電致變色液晶層246為該透光狀態，該第一光感測元件211用以感測通過該發光模組26之一第一入射光IN1，該第二光感測元件212用以感測直接入射至該第二光感測元件212之一第二入射光IN2，藉此，同時感測該顯示裝置20之前側與背側之入射光線。As shown in FIG. 7C , the firstlight sensing element 211 and the secondlight sensing element 212 of the present embodiment are different types of light sensing elements, namely, the back side illumination (BSI) type light sensing element and the front side illumination (FSI) type light sensing element. When the light emitting element does not emit light, that is, when the firstlight emitting element 262R to the fifthlight emitting element 264G do not emit light, the electrochromicliquid crystal panel 24 is in a light-transmitting state, that is, the electrochromicliquid crystal layer 246 is in the light-transmitting state. The firstlight sensing element 211 is used to sense a first incident light IN1 passing through thelight emitting module 26, and the secondlight sensing element 212 is used to sense a second incident light IN2 directly incident on the secondlight sensing element 212, thereby simultaneously sensing the incident light on the front and back sides of thedisplay device 20.

如第7D圖與第7E圖所示，其相當於第4C圖與第4D圖所示之實施例，在該電致變色液晶層246呈該非透光狀態時，即可反射該顯示裝置20前側之一第三入射光IN3至該第一光感測元件211，以及進一步設置一第一濾光層2111，用以感測該第三入射光IN3之特定波段或特定波長，因此即使在該發光模組26發光時，該第一光感測元件211及該第二光感測元件212之光感測功能仍不受到影響，其中可透過該控制處理電路17控制該發光模組26發光時，進一步控制該資料驅動電路19驅使該電致變色液晶層246呈該非透光狀態，或者是該控制處理電路17依據一輸入命令控制該資料驅動電路19驅使該電致變色液晶層246呈該非透光狀態。As shown in FIG. 7D and FIG. 7E, which are equivalent to the embodiments shown in FIG. 4C and FIG. 4D, when the electrochromicliquid crystal layer 246 is in the non-light-transmitting state, a third incident light IN3 at the front side of thedisplay device 20 can be reflected to the firstlight sensing element 211, and a first filter layer 2111 is further provided to sense a specific band or a specific wavelength of the third incident light IN3. Therefore, even when the light-emittingmodule 26 emits light, The light sensing functions of the firstlight sensing element 211 and the secondlight sensing element 212 remain unaffected, wherein thecontrol processing circuit 17 can control thelight emitting module 26 to emit light, and further control thedata driving circuit 19 to drive the electrochromicliquid crystal layer 246 to the non-light-transmitting state, or thecontrol processing circuit 17 controls thedata driving circuit 19 to drive the electrochromicliquid crystal layer 246 to the non-light-transmitting state according to an input command.

The driving circuit is coupled to thelight emitting module 26, and is coupled to the firstsensing control element 222 and the secondsensing control element 224. An electrochromicliquid crystal panel 24 is provided between the light emittingmodule 26 and thesensing control elements 222 and 224. Thesensing control elements 222 and 224 are coupled to thelight sensing elements 211 and 212. The present embodiment is described by taking thedata driving circuit 19 as an example. In step S10, The first and secondsensing control elements 222 and 224 control the first and secondlight sensing elements 211 and 212 to generate corresponding sensing signals SS to thecontrol processing circuit 17 when sensing the incident light IN1 and IN2. Therefore, in step S20, thecontrol processing circuit 17 generates a corresponding control signal CON to thedata driving circuit 19 according to the received sensing signal SS. Therefore, the control signal CON controls thedata driving circuit 19 to drive the light-emittingmodule 26 to emit light downward, and the control signal CON drives thedata driving circuit 19 to reduce or increase the brightness of the first red light R1, the first green light G1, the first blue light B1, the second red light R2 and the second red light G2.

Thecontrol element 2441, the seconddisplay control element 2442, the thirddisplay control element 2443, the fourthdisplay control element 2444 and the fifthdisplay control element 2445 are coupled to the first light-emittingcontrol element 2622, the second light-emittingcontrol element 2624, the third light-emittingcontrol element 2626, the fourth light-emittingcontrol element 2642 and the fifth light-emittingcontrol element 2644 respectively, so when the light-emittingmodules 16 and 26 emit light, the electrochromicliquid crystal panels 14 and 24 are synchronously switched to the non-light-transmitting state.
