Abstract
Description
[Technical field]
[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. [Background technology]
[0002] In existing display devices, photosensitive elements (such as cameras) are usually integrated to enrich the functions of the display device. At the same time, in order to increase the screen-to-body ratio of the display device, the area of the light-emitting surface of the display device corresponding to the photosensitive element can also be used for display, which is usually called a light-transmitting display area.
[0003] In order to drive the light-emitting devices in the light-transmitting display area without affecting the high light transmittance of the light-transmitting display area, the prior art mainly adopts two methods: one is to set the driving circuit for driving the light-emitting devices in the light-transmitting display area outside the light-transmitting display area, and connect the driving circuit and the light-emitting devices in the light-transmitting display area through leads. The other is to set the driving circuit for driving the light-emitting devices in the light-transmitting display area in the light-transmitting display area, and one driving circuit drives the light-emitting devices in multiple light-transmitting display areas.
[0004] However, the first method will affect the driving design of the pixels around the light-transmitting display area, and the driving effect of the light-emitting device in the light-transmitting display area is poor. The second method will result in less display information in the light-transmitting display area and poor picture fineness. Therefore, a new solution is urgently needed.

[0040] The applicant in this case has provided a solution to the problems existing in the prior art through careful and in-depth research.
[0041] Figure 1 A schematic diagram of a display panel provided in an embodiment of the present application, Figure 2 A schematic diagram of another display panel provided in an embodiment of the present application, Figure 3 for Figure 1 An enlarged view of the middle region Q.
[0042] The present application embodiment provides a display panel 01, such as Figure 1 and Figure 2As shown, the display panel 01 includes a main display area AA and a light-transmitting display area BB, the light transmittance of the light-transmitting display area BB is greater than the light transmittance of the main display area AA, and the main display area AA surrounds at least a portion of the light-transmitting display area BB.
[0043] Alternatively, if Figure 1 As shown, the light-transmitting display area BB is completely surrounded by the main display area AA.
[0044] Alternatively, if Figure 2 As shown, the main display area AA surrounds part of the light-transmitting display area BB.
[0045] Combination Figure 1 and Figure 3 As shown, the display panel 01 includes a plurality of pixel circuits 10, the plurality of pixel circuits 10 include a plurality of first pixel circuits 11 and a plurality of second pixel circuits 12, the light-transmitting display area BB includes a first area B1 and a second area B2, the first area B1 includes a plurality of first light-emitting devices 13, one first pixel circuit 11 is electrically connected to at least two first light-emitting devices 13, and the first pixel circuit 11 is used to drive the first light-emitting device 13 to emit light.
[0046] Optionally, one first pixel circuit 11 is electrically connected to two first light-emitting devices 13 , or one first pixel circuit 11 is electrically connected to four first light-emitting devices 13 .
[0047] It should be noted that Figure 3 It only illustrates the situation that one first pixel circuit 11 is electrically connected to two first light emitting devices 13 .
[0048] Optionally, the first light-emitting devices 13 electrically connected to the same first pixel circuit 11 have the same light-emitting color.
[0049] The second area B2 surrounds at least a portion of the first area B1, that is, the second area B2 may be located between the first area B1 and the main display area AA. The second area B2 includes a plurality of second light emitting devices 14, and the second pixel circuits 12 are electrically connected to the second light emitting devices 14 in a one-to-one correspondence. The second pixel circuits 12 are used to drive the second light emitting devices 14 to emit light.
[0050] That is to say, in the light-transmitting display area BB, at least two first light-emitting devices 13 in the first area B1 can be driven by the same first pixel circuit 11, and the first light-emitting devices 13 in the first area B1 adopt a "one-to-many" driving mode. One second light-emitting device 14 in the second area B2 is driven by one second pixel circuit 12, and the second light-emitting device 14 in the second area B2 adopts a "one-to-one" driving mode.
[0051] In the prior art, there are two main ways to drive the light-emitting devices in the light-transmitting display area BB. One is to set all the pixel circuits driving the light-emitting devices in the light-transmitting display area BB outside the light-transmitting display area BB, one pixel circuit drives one light-emitting device, and the pixel circuit is connected to the light-emitting device in the light-transmitting display area BB through a lead. The other is to set all the pixel circuits driving the light-emitting devices in the light-transmitting display area BB inside the light-transmitting display area BB, and one pixel circuit drives multiple light-emitting devices in the light-transmitting display area BB.
[0052] The inventor of the present application has found through research that, without reducing the display density of the light-transmitting display area BB, in the first driving mode, the number of pixel circuits driving the light-emitting devices in the light-transmitting display area BB is relatively large, and arranging them at the periphery of the light-transmitting display area BB will affect the driving design of the light-emitting devices around the light-transmitting display area BB, resulting in a complex design and increased process difficulty. In addition, the number of leads connecting the pixel circuits and the light-emitting devices in the light-transmitting display area BB is relatively large and long, which will also affect the transmittance of the light-transmitting display area BB.
[0053] In the second driving mode, each pixel circuit drives the light emitting devices of multiple light-transmitting display areas BB, and the light emitting devices of multiple light-transmitting display areas BB will display the same information, so that the light-transmitting display area BB displays less information and the fineness of the displayed picture is poor.
[0054] The inventor of the present application has considered the shortcomings of the two driving modes in the prior art and has provided a compromise solution that is easier to implement.
[0055] In the embodiment of the present application, the light-transmitting display area BB is provided to include a first area B1 and a second area B2, and a first pixel circuit 11 drives at least two first light-emitting devices 13 in the first area B1, and a second pixel circuit 12 drives a second light-emitting device 14 in the second area B2. In this way, the total number of the first pixel circuits 11 and the second pixel circuits 12 will not be too large while ensuring that the light-transmitting display area BB has more display information. Without reducing the display density of the light-transmitting display area BB, compared with the first driving method in the prior art, the influence on the driving design of the light-emitting devices around the light-transmitting display area BB can be reduced to reduce the design difficulty and preparation difficulty of the display panel 01, and the number of external leads can be reduced to ensure the high transmittance of the light-transmitting display area BB. Compared with the second driving method in the prior art, the display information of the light-transmitting display area BB can be increased, which is conducive to improving the picture fineness of the light-transmitting display area BB.
[0056] The embodiment of the present application can take into account the display effect and preparation process of the light-transmitting display area BB. While ensuring that the light-transmitting display area BB has a high picture fineness, it can reduce the driving design difficulty and preparation difficulty of the first light-emitting device 13 and the second light-emitting device 14 in the light-transmitting display area BB, which is beneficial to improving the overall performance of the display panel 01.
[0057] Figure 4 for Figure 1 Another zoomed-in view of the middle region Q.
[0058] Combination Figure 1 and Figure 4 As shown, in one embodiment of the present application, the first pixel circuit 11 is located in the light-transmitting display area BB, and the second pixel circuit 12 is located in the main display area AA. The first pixel circuit 11 can be located in the first area B1 of the light-transmitting display area BB, or in the second area B2 of the light-transmitting display area BB.
[0059] Optionally, the second pixel circuit 12 is located on a side of the main display area AA close to the light-transmitting display area BB.
[0060] Specifically, Figure 4 As shown, the main display area AA includes a transition display area A1 , which is connected to the light-transmitting display area BB. The transition display area A1 may surround the light-transmitting display area BB, and the second pixel circuit 12 is located in the transition display area A1 .
[0061] In the embodiment of the present application, the first pixel circuit 11 is arranged in the light-transmitting display area BB, the second pixel circuit 12 is arranged in the main display area AA, and one first pixel circuit 11 is electrically connected to at least two first light-emitting devices 13. Then, the number of pixel circuits 10 located in the light-transmitting display area BB is relatively small, which is beneficial to ensuring the high transmittance of the light-transmitting display area BB.
[0062] In addition, since the second area B2 is closer to the main display area AA than the first area B1, the second pixel circuit 12 driving the second light-emitting device 14 in the second area B2 is set in the main display area AA, which can reduce the length of the connection between the second pixel circuit 12 and the second light-emitting device 14, which is conducive to reducing the area occupied by the connection between the second pixel circuit 12 and the second light-emitting device 14 in the light-transmitting display area BB, thereby further ensuring the high transmittance of the light-transmitting display area BB. Moreover, the length of the connection between the second pixel circuit 12 and the second light-emitting device 14 is short, which can also reduce the loss of the signal transmitted by the second pixel circuit 12 on the connection line, which is conducive to improving the driving effect of the second pixel circuit 12.
[0063] In the embodiment of the present application, the first pixel circuit 11 for driving the first light-emitting device 13 in the light-transmitting display area BB is arranged in the light-transmitting display area BB, and the second pixel circuit 12 for driving the second light-emitting device 14 in the light-transmitting display area BB is arranged outside the light-transmitting display area BB. This ensures that the number of pixel circuits 10 in the light-transmitting display area BB and the periphery of the light-transmitting display area BB will not be excessive, and both the high transmittance of the light-transmitting display area BB and the convenient design of the pixel circuits 10 can be taken into account.
[0064] Figure 5 for Figure 1 Another zoomed-in view of the middle region Q.
[0065] Please continue to refer to Figure 3 In one embodiment of the present application, the first pixel circuit 11 and the second pixel circuit 12 are both located in the main display area.
[0066] Specifically, Figure 5 As shown, the main display area AA includes a transition display area A1 , which is connected to the light-transmitting display area BB. The transition display area A1 may surround the light-transmitting display area BB. The first pixel circuit 11 and the second pixel circuit 12 are both located in the transition display area A1 .
[0067] In the embodiment of the present application, the first pixel circuit 11 and the second pixel circuit 12 are both arranged in the main display area AA, so there is no need to arrange the first pixel circuit 11 and the second pixel circuit 12 in the light-transmitting display area BB, which is conducive to further ensuring the high light transmittance of the light-transmitting display area BB. Moreover, since one first pixel circuit 11 is electrically connected to at least two first light-emitting devices 13, the total number of first pixel circuits 11 and second pixel circuits 12 will not be too large, which is conducive to ensuring that the total number of connections between the first pixel circuit 11 and the first light-emitting device 13 and the second pixel circuit 12 and the second light-emitting device 14 will not be too large, so that it is easier to realize the driving design of the first pixel circuit 11 for the first light-emitting device 13 and the driving design of the second pixel circuit 12 for the second light-emitting device 14, which is conducive to reducing the design and preparation cost of the display panel 01.
[0068] Figure 6 A schematic diagram of a light-transmitting display area provided in an embodiment of the present application, Figure 7 A schematic diagram of another light-transmitting display area provided in an embodiment of the present application, Figure 8 A schematic diagram of another light-transmitting display area provided in an embodiment of the present application.
[0069] In one embodiment of the present application, Figure 6-Figure 8 As shown, in the light-transmitting display area BB, along a first direction X, the first areas B1 and the second areas B2 are alternately arranged, and the first direction X is at least one direction from the center of the light-transmitting display area BB to its edge.
[0070] The center point of the light-transmitting display area BB belongs to the first area B1.
[0071] That is to say, in the light-transmissive display area BB, along the direction from inside to outside, the first areas B1 and the second areas B2 may be arranged alternately.
[0072] Optionally, combined Figure 6-Figure 8 As shown, the shape of the light-transmitting display area BB is one of a circle, a square, and an ellipse.
[0073] For further information, please refer to Figure 6-Figure 8 The first area B1 and the second area B2 are both annular, and the shapes of the first area B1 and the second area B2 may be the same as the shape of the light-transmitting display area BB.
[0074] Specifically, Figure 6 As shown in FIG. 1 , when the light-transmitting display area BB is in a circular shape, the first area B1 and the second area B2 may both be in a circular ring shape. Figure 7 As shown in FIG. 1 , when the light-transmitting display area BB is in a square shape, the first area B1 and the second area B2 may both be in a square ring shape. Figure 8 As shown, when the light-transmitting display area BB is in an elliptical shape, the first area B1 and the second area B2 may both be in an elliptical ring shape.
[0075] It can be understood that since the connection length between the first pixel circuit 11 and the first light-emitting device 13 may be different from the connection length between the second pixel circuit 12 and the second light-emitting device 14, the effect of the first pixel circuit 11 driving the first light-emitting device 13 may be different from the effect of the second pixel circuit 12 driving the second light-emitting device 14, and there may be a difference in the display brightness of the first area B1 and the second area B2.
[0076] In the embodiment of the present application, the first area B1 and the second area B2 are arranged alternately, so that the human eye cannot capture the brightness difference between the display image of the first area B1 and the display image of the second area B2, which is beneficial to improving the brightness uniformity of the light-transmitting display area BB, thereby helping to improve the display quality of the display panel 01.
[0077] Fig. 9 A schematic diagram of another light-transmitting display area provided in an embodiment of the present application.
[0078] In one implementation of the embodiment of the present application, Fig. 9 As shown, the second area B2 is a strip-shaped pattern. That is, in the light-transmitting display area BB, the second area B2 may only surround a portion of the first area B1.
[0079] This implementation method is conducive to enriching the distribution diversity of the first area B1 and the second area B2 in the light-transmitting display area BB, and is conducive to further improving the operability of the driving design of the first light-emitting device 13 and the second light-emitting device 14 in the light-transmitting display area BB.
[0080] Fig.10 A schematic diagram of another light-transmitting display area provided in an embodiment of the present application.
[0081] In one embodiment of the present application, along the first direction X, the width of the first region B1 gradually decreases, and / or the width of the second region B2 gradually decreases.
[0082] That is to say, in the light-transmissive display area BB provided in the embodiment of the present application, the width of the first area B1 gradually decreases from the inside to the outside, or the width of the second area B1 gradually decreases. Alternatively, the width of the first area B1 gradually decreases from the inside to the outside, and the width of the second area B1 gradually decreases.
[0083] For example, Fig.10 As shown, the light-transmitting display area BB includes two first areas B1 and two second areas B2, and the first area B1 and the second area B2 may both be annular. The two first areas B1 include a first sub-area B11 and a second sub-area B22 arranged along the first direction X, and the second sub-area B22 is located on a side of the first sub-area B11 close to the main display area AA. The two second areas B2 include a third sub-area B21 and a fourth sub-area B22 arranged along the first direction X, and the fourth sub-area B22 is located on a side of the third sub-area B21 close to the main display area AA.
[0084] The width of the first sub-region B11 in the first direction X is W1, the width of the second sub-region B22 in the first direction X is W2, the width of the third sub-region B21 in the first direction X is W3, and the width of the fourth sub-region B22 in the first direction X is W4. W1>W2, and W3>W4.
[0085] It should be noted that Fig.10 It is only schematically shown that along the first direction X, the width of the first sub-region B11 is greater than the width of the second sub-region B12, and the width of the third sub-region B21 is greater than the width of the fourth sub-region B22. Of course, along the first direction X, only the width of the first sub-region B11 may be greater than the width of the second sub-region B12, or only the width of the third sub-region B21 may be greater than the width of the fourth sub-region B22.
[0086] It can be understood that when the light-transmitting display area BB includes multiple first areas B1 and multiple second areas B2, among the multiple first areas B1, the circumference of the first area B1 closer to the main display area AA is longer; among the multiple second areas B2, the circumference of the second area B2 closer to the main display area AA is longer.
[0087] In the embodiment of the present application, along the first direction X, when the width of the first region B1 gradually decreases, it is possible for multiple first regions B1 to occupy the same area in the light-transmitting display area BB, which is conducive to improving the uniformity of the first regions B1 in the light-transmitting display area BB. Moreover, without reducing the display density of the light-transmitting display area BB, the number of first light-emitting devices 13 included in each first region B1 can be approximately the same, which is also conducive to ensuring the uniformity of the display brightness of each first region B1.
[0088] When the width of the second region B2 gradually decreases along the first direction X, it is possible for multiple second regions B2 to occupy the same area in the light-transmitting display area BB, which is beneficial to improving the uniformity of the second regions B2 in the light-transmitting display area BB. Moreover, without reducing the display density of the light-transmitting display area BB, the number of second light-emitting devices 14 included in each second region B2 can be approximately the same, which is also beneficial to ensure the uniformity of the display brightness of each second region B2.
[0089] It should be noted that in the embodiment of the present application, along the first direction X, the light-emitting devices located at the outer edge of the first area B1 may belong to the first light-emitting devices 13 , and the light-emitting devices located at the outer edge of the second area B2 may belong to the second light-emitting devices 14 .
[0090] Fig.11 A schematic diagram of another light-transmitting display area provided in an embodiment of the present application.
[0091] In one embodiment of the present application, in two adjacent first regions B1 and second regions B2 along the first direction X, the second region B2 is located on a side of the first region B1 close to an edge of the light-transmitting display region BB, that is, the second region B2 is located on a side of the first region B1 close to the main display region AA. Along the first direction X, the width of the first region B1 is greater than the width of the second region B2.
[0092] For example, Fig.11 As shown, the second sub-region B12 in the first region B1 is adjacent to the fourth sub-region B22 in the second region B2 along the first direction X, and the fourth sub-region B22 is located on a side of the second sub-region B12 close to the main display area AA.
[0093] The width W2 of the second sub-region B12 along the first direction X is greater than the width W4 of the fourth sub-region B22 along the first direction X, that is, W2>W4.
[0094] Of course, in Fig.11 In the embodiment, the width W1 of the first sub-region B11 along the first direction X may also be greater than the width W3 of the third sub-region B21 along the first direction X, that is, W1>W3.
[0095] From the above analysis, it can be seen that, in the adjacent first area B1 and second area B2, the perimeter of the second area B2 closer to the main display area AA is greater than the perimeter of the first area B1.
[0096] In the embodiment of the present application, the width of the first area B1 is set to be greater than the width of the second area B2, so that the adjacent first area B1 and the second area B2 can occupy the same area in the light-transmitting display area BB, which is conducive to making the first area B1 and the second area B2 distributed more evenly in the light-transmitting display area BB. Moreover, without reducing the display density of the light-transmitting display area BB, the number of first light-emitting devices 13 included in the first area B1 can be approximately the same as the number of second light-emitting devices 14 included in the second area B2, which is also conducive to ensuring the display uniformity of the adjacent first area B1 and the second area B2, thereby ensuring the display uniformity of the light-transmitting display area BB, and further ensuring the display quality of the display panel 01.

[0098] The present application embodiment provides a display device 03, such as Fig.12 As shown, the display device 03 includes the display panel 01 provided in the above embodiment. The display device 03 provided in the embodiment of the present application can be an electronic device such as a mobile phone, a computer, a television, etc.
[0099] Please refer to Fig.13 The display device 03 further includes a photosensitive element 02. Along the thickness direction Z of the display device 03, the photosensitive element 02 overlaps with the light-transmitting display area BB in the display panel 01. The photosensitive element 02 may be an electronic device such as a camera or an infrared identifier.
[0100] In the display device 03, a light-transmitting display area BB is provided including a first area B1 and a second area B2, and a first pixel circuit 11 drives a first light-emitting device 13 in at least two first areas B1, and a second pixel circuit 12 drives a second light-emitting device 14 in a second area B2. In this way, while ensuring that the light-transmitting display area BB displays more information, the total number of the first pixel circuits 11 and the second pixel circuits 12 will not be too large, which is beneficial to taking into account the display effect and preparation process of the light-transmitting display area BB. While ensuring that the light-transmitting display area BB has a high picture fineness, the driving design difficulty and preparation difficulty of the first light-emitting device 13 and the second light-emitting device 14 in the light-transmitting display area BB can be reduced, which is beneficial to improving the overall performance of the display device 03.
[0101] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
