It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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.
The embodiment of the application provides a display device, can be applied to electronic equipment, electronic equipment can be the mobile terminal equipment that can initiatively show such as cell-phone, panel computer, can also be game station, Augmented Reality (AR) equipment, Virtual Reality (VR), on-vehicle computer, notebook computer, data storage device, audio playback device, video playback device, wearable equipment etc. have the equipment that display device shows passively, wherein wearable equipment can be intelligent bracelet, smart glasses etc.. In the passive display electronic device represented by the liquid crystal display, the optical fingerprint identification technology which can be mass-produced is not realized, and even some prototype machines which add the optical fingerprint identification technology reduce the display brightness of the display device due to the addition of the optical path structure and the photosensitive unit, thereby influencing the display quality. The display device of the embodiment of the application can improve the display brightness of the electronic equipment so as to solve the problem that the display brightness is reduced due to the fact that the optical fingerprint identification technology is added into the passively displayed electronic equipment.
The embodiment of the application provides a display device which comprises a display panel and a driving circuit. In order to more fully understand the display panel and the driving circuit of the display device according to the embodiment of the present application, the display panel and the driving circuit are respectively described in detail below.
For example, referring to fig. 1 to fig. 3, fig. 1 is a first structural schematic diagram of a display panel provided in the embodiment of the present application, fig. 2 is a second structural schematic diagram of the display panel provided in the embodiment of the present application, and fig. 3 is a third structural schematic diagram of the display panel provided in the embodiment of the present application. The embodiment of the present application provides a display panel 10, and the display panel 10 includes a plurality of pixel units 120 and a plurality of photosensitive units 140. The plurality of pixel units 120 are arranged in an array. Each pixel unit 120 includes at least four sub-pixels 1202 and a non-open area 1204, and the non-open area 1204 surrounds the at least four sub-pixels 1202. It is understood that the non-opening area 1204 is an area having a plurality of openings, and at least four sub-pixels 1202 are disposed corresponding to one opening. At least two of the at least four sub-pixels 1202 are the same color. At least one photosensitive unit 140 is disposed in the non-open area 1204 of the pixel unit 120. By arranging the sub-pixels 1202 with different colors in each pixel unit 120, at least two sub-pixels 1202 with the same color exist in each pixel unit 120, so that the display brightness of the display panel 10 can be improved, and the brightness requirement of a High Dynamic Range (HDR) image can be met.
For example, with continued reference to fig. 1, each pixel unit 120 includes four sub-pixels 1202. The four subpixels 1202 include three subpixels 1202 of different colors. The two sub-pixels 1202 in the four sub-pixels 1202 have the same color, and the arrangement of the four sub-pixels 1202 in each pixel unit 120 is the same.
Wherein the color of each sub-pixel 1202 is one of a first color, a second color, and a third color. For example, the first color may be R (Red ), the second color may be G (Green ), and the third color may be B (Blue ). The four sub-pixels 1202 of each pixel unit 120 are arranged in a line, and the colors of the four sub-pixels 1202 are the first color, the second color, the third color and the second color, respectively, i.e., the colors of the four sub-pixels 1202 arranged in a line are R, G, B and G, respectively. The four sub-pixels 1202 of the pixel unit 120 constitute a color combination of RGBG. The three different color sub-pixels 1202 in the pixel unit 120 form a RGB three-color mixture, which generates a composite color with different gray scales. And because the upper and lower adjacent positions of the G color sub-pixel 1202 also have the G color sub-pixel 1202, the brightness can be further improved. In addition, since two G color sub-pixels 1202 exist in the pixel unit 120, the display luminance can be significantly improved, and the high dynamic range image luminance requirement can be satisfied. In other embodiments, the first color may also be G or B, the second color may also be R or B, and the third color may also be R or G, which will not be described herein.
For another example, referring to fig. 2, the four sub-pixels 1202 of each pixel unit 120 are arranged in two rows and two columns, i.e., a 2 × 2 matrix. Wherein the two subpixels 1202 of one row are colored in the order of a first color and a second color and the two subpixels 1202 of the other row are colored in the order of a second color and a third color. It is understood that two subpixels 1202 of one row may be R and G, two subpixels 1202 of the other row are G and B, and R color subpixel 1202 of one row corresponds to G color subpixel 1202 of the other row, and four subpixels 1202 form pixel unit 120 of RGGB color combination. The three different color sub-pixels 1202 in the pixel unit 120 form a RGB three-color mixture, which generates a composite color with different gray scales. And because there are two G color sub-pixels 1202 in the pixel unit 120, the display brightness can be significantly improved, and the requirement for high dynamic range image brightness is met.
For example, with continued reference to fig. 3, each pixel unit 120 includes four sub-pixels 1202. The four subpixels 1202 include three subpixels 1202 of different colors. Two of the four subpixels 1202 are the same color. The four sub-pixels 1202 are arranged in a straight line.
The arrangement of the four sub-pixels 1202 in the partial pixel unit 120 is different. For example, the plurality of pixel units 120 are arranged to form M pixel rows and N pixel columns. Each pixel row includes at least one pixel cell 120. M and N may be integers greater than zero, for example, as shown with reference to fig. 3, a plurality of pixel cells 120 are arranged to form 12 pixel rows and 3 pixel columns. The six adjacent pixel rows form a pixel group, the arrangement modes of the corresponding pixel rows of the two adjacent pixel groups are the same, and the arrangement modes of the corresponding sub-pixels 1202 of the two adjacent pixel rows in each pixel group are different. For example, the colors of the four sub-pixels 1202 of the pixel unit 120 of the first pixel row in each pixel group are the first color, the second color, the third color and the second color in sequence. The colors of the four sub-pixels 1202 of the pixel unit 120 of the second pixel row are the second color, the first color, the second color, and the third color in this order. The colors of the four sub-pixels 1202 of the pixel unit 120 of the third pixel row are the third color, the second color, the first color, and the second color in this order. The colors of the four sub-pixels 1202 of the pixel unit 120 of the fourth pixel row are the second color, the third color, the second color, and the first color in this order. The colors of the four sub-pixels 1202 of the pixel unit 120 of the fifth pixel row are the third color, the second color, the first color, and the second color in this order. The colors of the four sub-pixels 1202 of the pixel unit 120 of the sixth pixel row are the second color, the first color, the second color, and the third color in this order. That is, the colors of the four sub-pixels 1202 of the six pixel units 120 of the first pixel column in one pixel group are: RGBG, GRGB, BGRG, GBGR, BGRG, GRGB. Wherein, sequentially can be understood as being arranged from left to right and from top to bottom. The four sub-pixels 1202 constitute the pixel unit 120 of the color combination of RGBG. The three different color sub-pixels 1202 in the pixel unit 120 form a RGB three-color mixture, which generates a composite color with different gray scales. And because there are two G color sub-pixels 1202 in the pixel unit 120, the display brightness can be significantly improved, and the requirement for high dynamic range image brightness is met.
In some embodiments, please refer to fig. 4, and fig. 4 is a fourth structural diagram of a display panel according to an embodiment of the present disclosure. The embodiment of the present application provides a display panel 10, where the display panel 10 includes a plurality of pixel units 120, and the plurality of pixel units 120 are arranged in an array. Each pixel cell 120 includes two first sub-pixel cells 122 and one second sub-pixel cell 124. One second sub-pixel unit 124 is located between two first sub-pixel units 122. Each first sub-pixel unit 122 includes three sub-pixels 1222 and a non-open area 1224, the non-open area 1224 surrounding the three sub-pixels 1222. Each second sub-pixel element 124 includes a sub-pixel 1242 and a non-open area 1244, the non-open area 1244 surrounding a sub-pixel 1242. The colors of two sub-pixels in the four sub-pixels formed by the first sub-pixel unit 122 and the adjacent second sub-pixel unit 124 are the same. The four sub-pixels include three different color sub-pixels. The at least one photosensitive unit 140 is disposed in the non-open area 1224 of the first sub-pixel unit 122 and/or the non-open area 1244 of the second sub-pixel unit 124. By arranging four sub-pixels with different colors in the adjacent first sub-pixel unit 122 and second sub-pixel unit 124 in each pixel unit 120, at least two sub-pixels with the same color exist in the four sub-pixels, so that the display brightness of the display panel 10 can be improved, and the brightness requirement of the high dynamic range image can be met.
The four sub-pixel arrangements of a part of the first sub-pixel units 122 and the adjacent second sub-pixel units 124 are different. For example, the plurality of pixel units 120 are arranged to form M pixel rows and N pixel columns, each pixel row including at least one pixel unit 120. M and N may be integers greater than zero, for example, as shown with reference to fig. 4, a plurality of pixel cells 120 are arranged to form 7 pixel rows and 1 pixel column.
The four adjacent pixel rows form a pixel group, the arrangement modes of the corresponding pixel rows of the two adjacent pixel groups are the same, and the arrangement modes of the corresponding sub-pixels of the two adjacent pixel rows in each pixel group are different. For example, the colors of the four sub-pixels of the first sub-pixel unit 122 of the first pixel row and the second sub-pixel unit 124 adjacent thereto in each pixel group are the first color, the second color, the third color and the second color in sequence. The colors of the four sub-pixels of the first sub-pixel unit 122 and the adjacent second sub-pixel unit 124 of the second pixel row are the second color, the first color, the second color and the third color in sequence. The colors of the four sub-pixels of the first sub-pixel unit 122 of the third pixel row and the second sub-pixel unit 124 adjacent thereto are the third color, the second color, the first color, and the second color in this order. The colors of the four sub-pixels of the first sub-pixel unit 122 and the second sub-pixel unit 124 adjacent thereto of the fourth pixel row are the second color, the third color, the second color, and the first color in this order. That is, the colors of the three sub-pixels 1222 of the first sub-pixel unit 122 and the one sub-pixel 1242 of the second sub-pixel unit 124 of the first pixel column in one pixel group are respectively: RGBG, GRGB, BGRG, GBGR. It can be understood that the colors of the seven sub-pixels of the pixel unit 120 of the first pixel column in one pixel group are respectively: RGBGRGGB, GRGBGRG, BGRGBGR, GBGRGBG. Therein, three sub-pixels 1222 and one sub-pixel 1242 constitute a color combination of RGBG. Three sub-pixels with different colors in the four sub-pixels form RGB three-color mixture to generate composite color with different gray scales. And because two sub-pixels of G color exist in the four sub-pixels, the display brightness can be obviously improved, and the requirement of high dynamic range image brightness is met.
