The display panel and the display device shorten the signal transmission distance between the circuit module and the sub-pixel by arranging the circuit module corresponding to the sub-pixel connected to the display light-transmitting area in the display light-transmitting area, thereby improving the time length uniformity of the signal received by the sub-pixel in the display light-transmitting area. Furthermore, the circuit module is arranged at the intersection of the signal traces, thereby reducing the arrangement area of the circuit module and the signal traces, and improving the light transmittance of the display light-transmitting area. In addition, the partial sub-pixel overlaps the circuit module, and the partial sub-pixel partially overlaps the signal traces, thereby improving the light-transmitting area and the light transmittance of the display light-transmitting area.

Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display panel and display device. Background Technology

[0002] In current organic light-emitting diode (OLED) panels, the camera is positioned below the screen, and the panel above the camera can still display normally while taking pictures; this is called under-display camera technology.

[0003] In the process of researching and practicing the existing technology, the inventors of this application discovered that, based on the current under-display camera technology, in order to improve the light transmittance of the display panel corresponding to the camera area, the pixel driving circuit of the sub-pixel connected to the camera area is placed outside the camera area. However, this processing method makes the signal reception time of the sub-pixel located at the center of the camera area much longer than the signal reception time of the sub-pixel located at the edge of the camera area, which means that the uniformity of the signal reception time of the sub-pixels in the camera area is poor.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific implementation methods described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, the embodiments can be combined with each other but will not be described in detail one by one. Unless otherwise stated, the directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device; the terms "first," "second," "third," etc. are only used as markings and do not impose numerical requirements or establish a sequence.

[0025] This application provides a display panel and a display device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0026] exist Figure 1 and Figure 2In the above plan view, the first direction F1 can be a direction parallel to one side of the display panel 100, and for example, it can be the lateral direction of the display panel 100. The second direction F2 can be a direction parallel to the other side of the display panel 100 in the above plan view, and it can be the longitudinal direction of the display panel 100. The third direction F3 can be the thickness direction of the display panel 100. Optionally, in some embodiments, the first direction F1 and the second direction F2 may not intersect perpendicularly.

[0027] The display panel 100 may have a rectangular shape in a top plan view, but the implementation is not limited to this. In some embodiments, the display panel 100 may have a rectangular shape with vertical corners or rounded corners in a top plan view. The display panel 100 may include two short sides extending in a first direction F1 and two long sides extending in a second direction F2 in a top plan view.

[0028] The display panel 100 may include a display area AA and a light-transmitting display area TA, with the display area AA located on at least one side of the light-transmitting display area TA. For example, the display area AA may surround the light-transmitting display area TA at its periphery, or the display area AA may partially surround the periphery of the light-transmitting display area TA.

[0029] The display area AA and the display light-transmitting area TA are both regions containing pixels of the displayed image. The display light-transmitting area TA is configured to provide a light transmission channel for the camera module.

[0030] Optionally, the camera module can be a camera module for face recognition, which includes a transmitter and a receiver, the transmitter being configured to emit infrared light and the receiver being configured to receive infrared light reflected from a human face.

[0031] exist Figure 1 and Figure 2 In this configuration, the display panel 100 includes two light-transmitting areas TA. One light-transmitting area TA is configured to provide a light transmission channel for the transmitter, and the other light-transmitting area TA is configured to provide a light transmission channel for the receiver. However, this is not a limitation. For example, a single light-transmitting area TA can be used to provide light transmission channels for both the transmitter and the receiver simultaneously. Alternatively, the display panel 100 may include a single light-transmitting area TA configured to provide a light transmission channel for a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0032] Optionally, the display panel 100 includes a substrate 1a, a driving circuit layer 1b, a pixel layer 1c, an encapsulation layer 1d, a touch layer 1e, an optical adhesive layer 1f, and a cover plate 1g. The driving circuit layer 1b is disposed on the substrate 1a, the pixel layer 1c is disposed on the driving circuit layer 1b, the encapsulation layer 1d is disposed on the pixel layer 1c, the touch layer 1e is disposed on the encapsulation layer 1d, the optical adhesive layer 1f is disposed on the touch layer 1e, and the cover plate 1g is disposed on the optical adhesive layer 1f.

[0033] It should be understood that the structure of the display panel 100 disclosed in this application is not limited to the above-described embodiments. For example, the touch layer 1e may also be disposed between the encapsulation layer 1d and the pixel layer 1c, or a portion of the touch layer 1e may be integrated into the pixel layer 1c, or at least a portion of the touch layer 1e may be integrated into the driving circuit layer 1b.

[0034] Optionally, pixel layer 1c includes multiple sub-pixels 111. The multiple sub-pixels 111 include a first sub-pixel R, a second sub-pixel B, and a third sub-pixel G. Any two of the first, second, and third sub-pixels emit different colors. The following explanation uses the example of the first sub-pixel R being a red sub-pixel, the second sub-pixel B being a blue sub-pixel, and the third sub-pixel G being a green sub-pixel, but is not limited to this.

[0035] Optionally, based on the fact that the first sub-pixel R is a red sub-pixel, the second sub-pixel B is a blue sub-pixel, and the third sub-pixel G is a green sub-pixel, the area of ​​the second sub-pixel B is greater than the area of ​​the first sub-pixel R and the area of ​​the third sub-pixel G, and the area of ​​the first sub-pixel R is greater than the area of ​​the third sub-pixel G.

[0036] It is important to understand that in organic light-emitting materials per unit area, the blue subpixel has the lowest luminous intensity, followed by the red subpixel, and the green subpixel has the highest. Therefore, by setting the area of ​​the blue subpixel to be the largest, the red subpixel to be the second largest, and the green subpixel to be the smallest, the uniformity of the display can be improved.

[0037] Figure 3 The diagram shown is a top plan view of the display area AA of a display panel 100 according to one or more embodiments of this application. Figure 3 As shown, in the display area AA, each sub-pixel 111 is connected to a corresponding pixel circuit 112, and each pixel circuit 112 is disposed below a corresponding sub-pixel 111. In the first direction F1, blue sub-pixels B and red sub-pixels R are alternately arranged to form a mixed-color sub-pixel row, and multiple green sub-pixels G are arranged to form a solid-color sub-pixel row. The mixed-color sub-pixel row and the solid-color sub-pixel row are alternately arranged along the second direction F2. In the second direction F2, blue sub-pixels B and red sub-pixels R are alternately arranged to form a mixed-color sub-pixel column, and multiple green sub-pixels G are arranged to form a solid-color sub-pixel column. The mixed-color sub-pixel column and the solid-color sub-pixel column are alternately arranged along the first direction F1.

[0038] Figure 4 This is a first top plan view of the display light-transmitting area TA of a display panel 100 according to one or more embodiments of this application. Figure 4 In the display area TA, the arrangement pattern of sub-pixels 111 is consistent with the arrangement pattern of sub-pixels 111 in the display area AA, but it is not limited to this. For example, the arrangement patterns of sub-pixels 111 in the two areas can also be different.

[0039] Optionally, in the display light-transmitting area TA, the first sub-pixel R and the second sub-pixel B are alternately arranged along the first direction F1 to form a mixed-color sub-pixel row. Multiple third sub-pixels G are arranged along the first direction F1 to form a solid-color sub-pixel row. The first sub-pixel R and the second sub-pixel B are alternately arranged along the second direction F2 to form a mixed-color sub-pixel column. Multiple third sub-pixels G are arranged along the second direction F2 to form a solid-color sub-pixel column. In the first direction F1, the mixed-color sub-pixel column and the solid-color sub-pixel column are arranged alternately. In the second direction F2, the mixed-color sub-pixel row and the solid-color sub-pixel row are arranged alternately.

[0040] It should be noted that the underlying logic of the Sub-Pixel Rendering (SPR) algorithm can be applied to the following driving schemes: the first type (such as...) Figure 4 As shown), the first pixel circuit pr simultaneously drives two first sub-pixels R, the second pixel circuit pb simultaneously drives two second sub-pixels B, and the third pixel circuit pg simultaneously drives four third sub-pixels G; the second method uses the first pixel circuit pr to simultaneously drive two first sub-pixels R, the second pixel circuit pb to simultaneously drive two second sub-pixels B, and the third pixel circuit pg to simultaneously drive two third sub-pixels G; the third method (as shown) Figure 10 As shown, the first pixel circuit pr simultaneously drives four first sub-pixels R, the second pixel circuit pb simultaneously drives four second sub-pixels B, and the third pixel circuit pg simultaneously drives four third sub-pixels G.

[0041] based on Figure 4 For the driver solution, please refer to Figure 5 , Figure 5 This is a schematic view showing the circuit connections of a display panel 100 according to one or more embodiments of this application. Figure 5 In the driving circuit layer 1b, at least a portion of multiple pixel circuits 112 and signal traces 2xh are included.

[0042] The multiple pixel circuits 112 include a first pixel circuit pr, a second pixel circuit pb, and a third pixel circuit pg. The first pixel circuit pr drives a first sub-pixel R, the second pixel circuit pb drives a second sub-pixel B, and the third pixel circuit pg drives a third sub-pixel G.

[0043] In the display area AA, multiple pixel circuits 112 are arranged according to the arrangement of sub-pixels 111. In the display light-transmitting area TA, in the first direction F1, multiple pixel circuits 112 include circuit modules 10a, and each circuit module 10a is arranged in the order of first pixel circuit pr, third pixel circuit pg, and second pixel circuit pb.

[0044] The multiple signal traces 2xh include multiple scan lines s1, multiple data lines s2, and an anode power supply trace s4. The scan lines s1, data lines s2, and anode power supply trace s4 all extend from the display area AA to the display light-transmitting area TA. The anode power supply trace s4 includes multiple first trace sections s41 and multiple second trace sections s42, which are intersected and connected to form a grid structure.

[0045] It should be noted that scan line s1 is connected to pixel circuit 112 and provides scan signal SACN to pixel circuit 112. Data line s2 is connected to pixel circuit 112 and provides data signal DATA to pixel circuit 112. Anode power supply line s4 is connected to pixel circuit 112 and provides anode voltage signal VDD to pixel circuit 112.

[0046] In the display area AA, the scan line s1 and the first trace s41 extend along the first direction F1, and the data line s2 and the second trace s42 extend along the second direction F2.

[0047] It is important to understand that, based on the SPR algorithm, the arrangement of pixel circuits 112 in the light-transmitting area TA is the same as the arrangement of the even-numbered rows in the display area AA. Therefore, in the light-transmitting area TA, the scan lines s1 and the first trace s41 of the even-numbered rows in the display area AA extend to the light-transmitting area TA and connect to the pixel circuits 112 arranged in the same row. The data lines s2 and the second trace s42 of the solid color sub-pixel column in the display area AA extend to the light-transmitting area TA and connect to the third pixel circuit pg. The data lines s2 and the second trace s42 of the mixed color sub-pixel column in the display area AA extend to the light-transmitting area TA and connect to the first pixel circuit pr. The data lines s2 and the second trace s42 of the mixed color sub-pixel column in the display area AA extend to the light-transmitting area TA and connect to the second pixel circuit pb.

[0048] It should be noted that when the display panel 100 is driven by a single-side gate or by a dual-side gate, the scan lines s1 of the odd-numbered rows in the display area AA can pass through the display light-transmitting area TA to achieve the display of the entire row of sub-pixels 111, but the scan lines s1 of the odd-numbered rows are not connected to the circuit module 10a in the display light-transmitting area TA; when the display panel 100 is driven by a dual-side gate, the scan lines s1 of the odd-numbered rows in the display area AA do not need to pass through the display light-transmitting area TA to achieve the display of the entire row of sub-pixels 111.

[0049] The extra data line s2 in the display area AA corresponding to the display light-transmitting area TA can pass through the display light-transmitting area TA to realize the display of the entire column of sub-pixels 111; or it can not pass through the display light-transmitting area TA and achieve the display of the entire column of sub-pixels 111 through other routing methods.

[0050] The first trace s41 in the odd-numbered row of the display area AA corresponding to the display light-transmitting area TA may or may not pass through the display light-transmitting area TA. The additional second trace s42 in the display area AA corresponding to the display light-transmitting area TA may or may not pass through the display light-transmitting area TA.

[0051] It is necessary to understand that Figure 4 and Figure 5 The embodiments shown are only one implementation of this application, but are not limited thereto.

[0052] Figure 6 What is shown is Figure 4 An enlarged schematic view. In Figure 4 and Figure 6 In the display, multiple sub-pixels 111 are disposed in the display light-transmitting area TA. Multiple circuit modules 10a are disposed in the display light-transmitting area TA. Circuit module 10a includes at least three pixel circuits 112. Each pixel circuit 112 connects to at least two sub-pixels 111. Multiple signal traces 2xh extend from the display area AA into the display light-transmitting area TA, and the signal traces 2xh are configured to provide electrical signals to the pixel circuits 112.

[0053] It should be understood that at least three pixel circuits 112 are grouped together to form circuit module 10a to save layout area of ​​pixel circuits 112. Pixel circuits 112 are configured to drive sub-pixels 111 to emit light. Pixel circuits 112 can be one of the following circuits: 7T1C circuit, 6T1C circuit, 5T1C circuit, and 3T1C circuit. Since pixel circuits 112 are conventional circuits, they will not be described in detail here.

[0054] It is understood that the display panel 100 of this application embodiment provides a circuit module 10a corresponding to the sub-pixel 111 connected to the display light-transmitting area TA in order to shorten the signal transmission distance between the circuit module 10a and the sub-pixel 111, thereby improving the uniformity of signal reception time of the sub-pixel 111 in the display light-transmitting area TA.

[0055] Secondly, since the pixel circuit 112 connects at least two sub-pixels 111, at least one pixel circuit 112 can be saved to increase the light-transmitting area of ​​the display light-transmitting region TA.

[0056] Optionally, the anodes of all sub-pixels 111 connected to the same pixel circuit 112 are connected through a first lead yx1, and the pixel circuit 112 is connected to the first lead yx1 or an anode through a second lead yx2, so that one pixel circuit 112 drives at least two sub-pixels 111 to emit light.

[0057] Optionally, in some embodiments, both the first lead yx1 and the second lead yx2 are transparent leads to increase the light-transmitting area of ​​the light-transmitting region TA, thereby improving its light transmittance. For example, the materials of the first lead yx1 and the second lead yx2 can be metal oxides or transparent metals, such as indium tin oxide, indium zinc oxide, silver, platinum, etc.

[0058] In the display panel 100 viewed from above, multiple signal traces 2xh are intersected to form multiple intersection regions jx. At least some of the multiple circuit modules 10a are disposed on the intersection regions jx. One circuit module 10a is correspondingly overlapped with a portion of the multiple sub-pixels 111. The signal traces 2xh partially overlap with a portion of the multiple sub-pixels 111.

[0059] The display panel 100 of this application embodiment arranges the circuit module 10a in the intersection area jx of the signal trace 2xh, which can reduce the arrangement area of ​​the circuit module 10a and the signal trace 2xh, thereby improving the light transmittance of the display light-transmitting area TA; in addition, by using some sub-pixels 111 to overlap with the circuit module 10a and some sub-pixels 111 to partially overlap with the signal trace 2xh, the light-transmitting area is increased, thereby improving the light transmittance of the display light-transmitting area TA.

[0060] Optionally, in some embodiments of this application, the multiple signal traces 2xh further include multiple reset traces s3.

[0061] The extension directions of scan line s1 and reset line s3 both intersect the extension direction of data line s2. The intersection point of the first routing section s41 and the second routing section s42 is located in the intersection region jx. In the first direction F1, data line s2 and the second routing section s42 are arranged. In the second direction F2, which intersects with the first direction F1, scan line s1, reset line s3, and the first routing section s41 are arranged.

[0062] It should be noted that the reset trace s3 is connected to the pixel circuit 112 and provides a reset signal VI to the pixel circuit 112.

[0063] In the first direction F1, a scan line s1 connects to multiple pixel circuits 112, and a reset line s3 connects to multiple pixel circuits 112. In the second direction F2, a data line s2 connects to multiple pixel circuits 112. The anode power supply line s4 has a grid structure and can connect to multiple pixel circuits 112, for example, it can connect to all pixel circuits 112.

[0064] Optionally, the first trace portion s41 and multiple second trace portions s42 of the anode power supply trace s4 can be arranged on the same layer or on different layers and connected through vias. The scan line s1 and the reset trace s3 are both arranged on different layers from the data line s2 to avoid short circuits.

[0065] It should be noted that as long as the scan line s1, data line s2, reset line s3 and anode power supply line s4 are not short-circuited with each other, this application does not impose specific restrictions on the film layer position and connection method of the four.

[0066] Optionally, in some embodiments, at least one of the data line s2 and the second routing portion s42 partially overlaps with a portion of the plurality of sub-pixels 111. At least one of the scan line s1, the reset routing line s3, and the first routing portion s41 partially overlaps with a portion of the plurality of sub-pixels 111.

[0067] Understandably, since sub-pixel 111 also has light-blocking properties, sub-pixel 111 is arranged on at least one of the scan line s1, data line s2, reset line s3 and anode power supply line s4 to overlap the light-blocking area and thus increase the light-transmitting area.

[0068] Optionally, in some embodiments of this application, the plurality of sub-pixels 111 include a plurality of arrayed minimum repeating units 10b. Each minimum repeating unit 10b includes at least two first sub-pixels R, at least two second sub-pixels B, and at least two third sub-pixels G. The first sub-pixels R, the second sub-pixels B, and the third sub-pixels G each emit different colors.

[0069] Each circuit module 10a is connected to a minimum repeating unit 10b. In circuit module 10a, one pixel circuit 112 of the plurality of pixel circuits 112 is connected to at least two first sub-pixels R. Another pixel circuit 112 of the plurality of pixel circuits 112 is connected to at least two second sub-pixels B. Yet another pixel circuit 112 of the plurality of pixel circuits 112 is connected to at least two third sub-pixels G.

[0070] It is understandable that the more sub-pixels 111 connected to a pixel circuit 112, the more pixel circuits 112 are saved, and the more light-transmitting area is achieved.

[0071] Optionally, in some embodiments of this application, each circuit module 10a is disposed within the region of a minimum repeating unit 10b.

[0072] It is understandable that each minimum repeating unit 10b is provided with a corresponding circuit module 10a, so that each circuit module 10a can transmit signals to the minimum repeating unit 10b connected to it, and at the same time, the circuit modules 10a are evenly arranged in the display light-transmitting area TA to improve the duration uniformity of driving sub-pixels.

[0073] Optionally, in some embodiments of this application, the minimum repeating unit 10b includes two first sub-pixels R, two second sub-pixels B, and four third sub-pixels G, and the circuit module 10a includes three pixel circuits 112, one pixel circuit 112 connecting the two first sub-pixels R, another pixel circuit 112 connecting the two second sub-pixels B, and yet another pixel circuit 112 connecting the four third sub-pixels G.

[0074] Combination Figure 5 In other words, the first pixel circuit pr simultaneously drives two first sub-pixels R, the second pixel circuit pb simultaneously drives two second sub-pixels B, and the third pixel circuit pg simultaneously drives four third sub-pixels G.

[0075] Optionally, in the smallest repeating unit 10b of the display panel 100 from a top-down view (e.g. Figure 6 As shown), two first sub-pixels R and two second sub-pixels B are provided at the four corners of the circuit module 10a. The two first sub-pixels R and the two second sub-pixels B are respectively partially overlapped with the circuit module 10a. The circuit module 10a is overlapped with a third sub-pixel G. At least one of the data line s2 and the second routing part s42 is partially overlapped with another third sub-pixel G. At least one of the scan line s1, the reset routing line s3 and the first routing part s41 is partially overlapped with yet another third sub-pixel G.

[0076] The above design can increase the light-transmitting area of ​​the display's light-transmitting zone (TA), thereby improving the light transmittance.

[0077] Please continue to refer to Figure 6 Optionally, in some embodiments of this application, the display panel 100 further includes a light-shielding layer 1h located in the light-transmitting area TA. The light-shielding layer 1h is located on the side of the circuit module 10a away from the sub-pixel 111. The light-shielding layer 1h includes multiple first light-shielding portions h01 extending along a first direction F1 and multiple second light-shielding portions h02 extending along a second direction F2. The multiple first light-shielding portions h01 and multiple second light-shielding portions h02 are intersected to form multiple light-transmitting openings tg1, and a third light-shielding portion h03 is formed at the intersection of the first light-shielding portions h01 and the second light-shielding portions h02.

[0078] In the display light-transmitting area TA of the display panel 100 from a top-down perspective, the scan line s1, the reset line s3 and the first line portion s41 are all arranged to overlap with the first light-shielding portion h01, the data line s2 and the second line portion s42 are all arranged to overlap with the second light-shielding portion h02, and the circuit module 10a is arranged to overlap with the third light-shielding portion h03.

[0079] It should be noted that the patterned light-shielding layer 1h is disposed on the side of the driving circuit layer 1b close to the substrate 1a, and blocks the circuit module 10a and signal traces 2xh. This can reduce the risk of light emitted by the camera module shining on the thin-film transistors of the circuit module 10a, thereby improving the stability of the circuit module 10a. At the same time, it reduces the risk of light signals emitted by the camera module being reflected back to the receiver by the circuit module 10a and signal traces 2xh, causing a decrease in recognition accuracy. Furthermore, the light-shielding layer 1h can reduce the risk of stray light entering the camera module by blocking the circuit module 10a and signal traces 2xh.

[0080] Optionally, in some embodiments of this application, a plurality of sub-pixels 111 are arranged in rows along a first direction F1. A plurality of sub-pixels 111 are arranged in columns along a second direction F2. One row of sub-pixels 111 in every four adjacent rows overlaps with the first light-shielding portion h01. One column of sub-pixels 111 in every at least four adjacent columns overlaps with the second light-shielding portion h02, and at least one sub-pixel 111 overlaps with the circuit module 10a.

[0081] It is understandable that by using a light-shielding layer 1h and overlapping some sub-pixels 111, the light-transmitting area can be increased, thereby increasing the light transmittance.

[0082] Optionally, the material of the light-shielding layer 1h can be a black organic material or a metallic material, such as molybdenum or a combination of titanium and molybdenum.

[0083] Please refer to Figure 7 , Figure 7 The diagram shows a layout of the light-shielding layer 1h and sub-pixels 111 in the display panel 100 of one or more embodiments of this application.

[0084] In some embodiments of this application, the minimum repeating unit 10b includes two first sub-pixels R, two second sub-pixels B, and four third sub-pixels G. The first sub-pixels R and second sub-pixels B are alternately arranged along a first direction F1 to form mixed-color sub-pixel rows. Multiple third sub-pixels G are arranged along a second direction F2 to form solid-color sub-pixel rows. The first sub-pixels R and second sub-pixels B are alternately arranged along the second direction F2 to form mixed-color sub-pixel columns. Multiple third sub-pixels G are arranged along the second direction F2 to form solid-color sub-pixel columns. In the first direction F1, the mixed-color sub-pixel columns and the solid-color sub-pixel columns are alternately arranged. In the second direction F2, the mixed-color sub-pixel rows and the solid-color sub-pixel rows are alternately arranged.

[0085] In other words, based on Figure 4 and Figure 6 In a corresponding embodiment, in the display light-transmitting area TA of the display panel 100 from a top-view perspective, one row of the solid-color sub-pixel rows in every two adjacent rows overlaps with the first light-shielding portion h01. One column of the solid-color sub-pixel columns in every two adjacent columns overlaps with the second light-shielding portion h02. Each third light-shielding portion h03 partially overlaps with two first sub-pixels R and two second sub-pixels B, and each third light-shielding portion h03 overlaps with a third sub-pixel G.

[0086] It is understandable that the third light-blocking part h03 only occupies the layout area of ​​four sub-pixels 111, and the third light-blocking part h03 does not fully cover the four sub-pixels 111 in the four corner areas in order to increase the light-transmitting area.

[0087] Please refer to Figure 8 , Figure 8 What is shown is Figure 7 An enlarged schematic diagram of section M in the middle.

[0088] Optionally, in some embodiments of this application, the pattern of the light-transmitting opening tg1 in the display light-transmitting area TA of the display panel 100 from a top-view perspective is an asymmetrical pattern.

[0089] It is understandable that the emitted light signal from the camera module will undergo diffraction after passing through the light-transmitting port tg1 of the light-shielding layer for 1 hour. Since the generation of the diffraction effect is closely related to the interference phenomenon when light waves encounter periodic structures, the embodiments of this application set an asymmetric pattern for the light-transmitting port tg1 to disrupt the periodic structure of the light-transmitting port tg1, reduce the occurrence of interference phenomena, and reduce the diffraction effect. At the same time, the shape of the asymmetric pattern can change the distribution and intensity of the diffracted light, which helps to reduce the intensity of diffracted light in a specific direction and reduce unnecessary diffracted light to reduce the diffraction effect.

[0090] Optionally, in some embodiments of this application, the pattern of the light-transmitting opening tg1 includes a first side g01, a second side g02, a third side g03, a fourth side g04, a first corner g11, a second corner g12, a third corner g13, and a fourth corner g14. The first side g01 and the third side g03 are arranged opposite each other and extend along a first direction F1, while the second side g02 and the fourth side g04 are arranged opposite each other and extend along a second direction F2. The first corner g11 connects the first side g01 and the second side g02, the second corner g12 connects the second side g02 and the third side g03, the third corner g13 connects the third side g03 and the fourth side g04, and the fourth corner g14 connects the fourth side g04 and the first side g01.

[0091] Any two of the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 are asymmetrically arranged.

[0092] It is understandable that by setting any two of the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 to be asymmetrical, the intensity of diffracted light in the diagonal direction can be reduced, thereby reducing the diffraction effect.

[0093] Optionally, in some embodiments of this application, at least one of the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 has at least one sub-corner tq, the number of sub-corner tq of the second corner g12 is different from the number of sub-corner tq of the third corner g13, and / or the number of sub-corner tq of the first corner g11 is different from the number of sub-corner tq of the fourth corner g14.

[0094] It is understandable that by setting different numbers of sub-corners tq in the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14, any two of the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 can be set asymmetrically.

[0095] Secondly, the setting of the sub-corner tq has the effect of scattering light, which can further improve the distribution of diffracted light intensity in the diagonal direction, thereby reducing the diffraction effect.

[0096] In some embodiments, the distribution of diffracted light intensity in the diagonal direction can be further improved by setting the width of the third corner g13 in the second direction F2 to be different from the width of the second corner g12 in the second direction F2, and / or the width of the first corner g11 in the second direction F2 to be different from the width of the fourth corner g14 in the second direction F2, thereby reducing the diffraction effect.

[0097] In some embodiments, the distribution of diffracted light intensity in the diagonal direction can be further improved by setting the total length of the third corner g13 to be different from the total length of the second corner g12, and / or the total length of the first corner g11 to be different from the total length of the fourth corner g14, thereby reducing the diffraction effect.

[0098] In some embodiments, the angle between the sub-angle tq of the third corner g13 and the sub-angle tq of the second corner g12 can be set to be different, and / or the angle between the sub-angle tq of the first corner g11 and the sub-angle tq of the fourth corner g14 can be set to be different, so as to further improve the distribution of diffracted light intensity in the diagonal direction and thereby reduce the diffraction effect.

[0099] Please refer to Figure 9 , Figure 9 Based on Figure 7 and Figure 8 Diffraction simulation diagram of an embodiment of the pattern layout of the light-shielding layer 1h, according to Figure 9 As can be seen, the diffraction pattern is clear.

[0100] Figure 10 The diagram shown is a second top view of the display light-transmitting area TA of the display panel 100 according to an embodiment of this application. Figure 11 What is shown is based on Figure 10 A schematic view of the circuit connections of the display panel 100 corresponding to the embodiment. Figure 12 yes Figure 10 A partially enlarged schematic view. Figure 13 yes Figure 12 A schematic diagram showing the light-shielding layer 1h and sub-pixel 111 retained in the middle. Figure 14 What is shown is Figure 13 An enlarged schematic diagram of part N in the diagram.

[0101] exist Figures 10 to 13 In this document, parts that differ from the embodiments described above will be described to avoid redundancy.

[0102] Please refer to Figure 10 and Figure 11 The smallest repeating unit 10b includes four first sub-pixels R, four second sub-pixels B, and eight third sub-pixels G. The circuit module 10a includes four pixel circuits 112, one pixel circuit 112 is connected to the four first sub-pixels R, another pixel circuit 112 is connected to the four second sub-pixels B, and the remaining two pixel circuits 112 are each connected to the four third sub-pixels G.

[0103] In other words, in a circuit module 10a, the first pixel circuit pr simultaneously drives four first sub-pixels R, the second pixel circuit pb simultaneously drives four second sub-pixels B, and the two third pixel circuits pg each drive four third sub-pixels G.

[0104] exist Figure 11 In the display area AA, multiple pixel circuits 112 are arranged according to the arrangement of sub-pixels 111. In the display light-transmitting area TA, in the first direction F1, the multiple pixel circuits 112 include circuit modules 10a, and each circuit module 10a is arranged in the order of first pixel circuit pr, third pixel circuit pg, second pixel circuit pb, and third pixel circuit pg.

[0105] Please refer to Figure 12 In some embodiments of this application, in the smallest repeating unit 10b of the display panel 100 from a top-view perspective, a first sub-pixel R overlaps with the circuit module 10a; two second sub-pixels B and four third sub-pixels G partially overlap with the circuit module 10a; at least one of the data line s2 and the second routing portion s42 partially overlaps with another second sub-pixel B; and at least one of the scan line s1, the reset routing line s3, and the first routing portion s41 partially overlaps with another first sub-pixel R. At least one of the scan line s1, the reset routing line s3, and the first routing portion s41 partially overlaps with the two second sub-pixels B that partially overlap with the circuit module 10a.

[0106] It is understandable that, since the second sub-pixel B has the largest area, more of the second sub-pixel B is arranged on the signal trace 2xh to reduce the light-blocking area, thereby increasing the light-transmitting area of ​​the display light-transmitting area TA and thus improving the light transmittance.

[0107] Please refer to Figure 12 It should be noted that, Figure 12 The second routing section s42 is not shown, but this does not mean that there is no second routing section s42. For example, the second routing section s42 is connected to the first routing section s41 by means of vias to transfer other film layers.

[0108] Please refer to Figure 13 Optionally, in some embodiments of this application, the minimum repeating unit 10b includes four first sub-pixels R, four second sub-pixels B, and eight third sub-pixels G. The first sub-pixels R and second sub-pixels B are arranged alternately along a first direction F1 to form mixed-color sub-pixel rows, and the plurality of third sub-pixels G are arranged along a second direction F2 to form solid-color sub-pixel rows. The first sub-pixels R and second sub-pixels B are arranged alternately along the second direction F2 to form mixed-color sub-pixel columns, and the plurality of third sub-pixels G are arranged along the second direction F2 to form solid-color sub-pixel columns. In the first direction F1, the mixed-color sub-pixel columns and the solid-color sub-pixel columns are arranged alternately. In the second direction F2, the mixed-color sub-pixel rows and the solid-color sub-pixel rows are arranged alternately.

[0109] In other words, based on Figure 10 and Figure 12 In a corresponding embodiment, in the display light-transmitting area TA of the display panel 100 from a top-down view, one row of the mixed color sub-pixel row in every two adjacent rows overlaps with the first light-shielding part h01, one column of the mixed color sub-pixel column in every two adjacent columns overlaps with the second light-shielding part h02, and each third light-shielding part h03 overlaps with one first sub-pixel R, two second sub-pixels B, and four third sub-pixels G.

[0110] It is understandable that the first light-shielding part h01 is used to block the row of mixed color sub-pixels with a large light-emitting area, the second light-shielding part h02 is used to block the column of mixed color sub-pixels with a large light-emitting area, and the third light-shielding part h03 is used to block more sub-pixels 111 in order to increase the light-transmitting area.

[0111] Please refer to Figure 14 The first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 are asymmetrically arranged; and at least one of the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14 has at least one sub-corner tq, the number of sub-corner tq of the second corner g12 is different from the number of sub-corner tq of the third corner g13, and / or, the number of sub-corner tq of the first corner g11 is different from the number of sub-corner tq of the fourth corner g14.

[0112] exist Figure 14 In the first corner g11, the second corner g12, the third corner g13, and the fourth corner g14, the number of sub-corners tq is different.

[0113] Please refer to Figure 15 , Figure 15 Based on Figure 13 and Figure 14 Diffraction simulation diagram of an embodiment of the pattern layout of the light-shielding layer 1h, according to Figure 15 As can be seen, the diffraction pattern is clear.

[0114] Figure 16 The diagram shown is a third top view of the display light-transmitting area TA of the display panel 100 according to an embodiment of this application. Figure 17 The diagram shown is a fourth top view of the display light-transmitting area TA of the display panel 100 according to an embodiment of this application. Figure 18 The diagram shown is a fifth top view of the display light-transmitting area TA of the display panel 100 according to an embodiment of this application. Figure 19 The diagram shown is a sixth top view of the display light-transmitting area TA of the display panel 100 according to an embodiment of this application.

[0115] exist Figures 16 to 19In this document, parts that differ from the embodiments described above will be described to avoid redundancy.

[0116] It should be noted that, Figure 16 and Figure 17 It is a driving architecture based on the first pixel circuit pr simultaneously driving two first sub-pixels R, the second pixel circuit pb simultaneously driving two second sub-pixels B, and the third pixel circuit pg simultaneously driving four third sub-pixels G. Figure 18 and Figure 19 It is a driving architecture based on the first pixel circuit pr simultaneously driving four first sub-pixels R, the second pixel circuit pb simultaneously driving four second sub-pixels B, and the third pixel circuit pg simultaneously driving four third sub-pixels G.

[0117] Please refer to Figures 16 to 19 In some embodiments of this application, a portion of the minimum repeating units 10b are arranged in an array to form a maximum repeating unit 10c, and a plurality of circuit modules 10a are arranged in the middle region of the maximum repeating unit 10c.

[0118] Optionally, multiple circuit modules 10a are arranged along the first direction F1.

[0119] in, Figure 16 The largest repeating unit 10c shown is formed by an array of four smallest repeating units 10b. Figure 17 The largest repeating unit 10c shown is formed by an array of sixteen smallest repeating units 10b. Figure 18 The largest repeating unit 10c shown is formed by an array of two smallest repeating units 10b. Figure 19 The largest repeating unit 10c shown is formed by an array of eight smallest repeating units 10b.

[0120] It is understandable that the largest repeating unit 10c can also be formed by an array of other numbers of the smallest repeating units 10b, such as 24, 32, 36, 40, 48, 56, 60, 64, 72, 80, 84, 96, 112 or 128.

[0121] Please refer to Figure 20 and Figure 21 , Figure 20 The diagram shown is a top view of a display device 1000 according to an embodiment of this application. Figure 21 The diagram shown is a cross-sectional plan view of a display device 1000 according to an embodiment of this application.

[0122] Accordingly, this application also provides a display device 1000, which includes a camera module 200 and a display panel 100 as described in any of the above embodiments. The camera module 200 is disposed on the backlight side of the display panel 100 and is disposed corresponding to the display light-transmitting area TA.

[0123] The camera module 200 includes a transmitter 21 and a receiver 22. The transmitter 21 is configured to emit infrared light, and the receiver 22 is configured to receive infrared light reflected from a face. The transmitter 21 corresponds to one display light-transmitting area TA, and the receiver 22 corresponds to another display light-transmitting area TA. However, this is not a limitation. For example, a single display light-transmitting area TA can be used to provide a light-transmitting channel for both the transmitter 21 and the receiver 22; or the display panel 100 may include one display light-transmitting area TA, and the camera module 200 may be a conventional camera module, such as a single-camera module, a multi-camera module, or an infrared camera module.

[0124] It should be noted that the structure of the display panel 100 of the display device 1000 in this application embodiment is similar to or the same as the structure of the display panel 100 of the above embodiments. Please refer to [link / reference] for details. Figures 1 to 19 The relevant explanations will not be repeated here.

[0125] The display device 1000 of this application improves the uniformity of signal reception time of sub-pixels 111 in the display light-transmitting area TA by placing circuit modules 10a corresponding to sub-pixels 111 connected to the display light-transmitting area TA in the display light-transmitting area TA, thereby shortening the signal transmission distance between the circuit modules 10a and sub-pixels 111. Secondly, placing the circuit modules 10a at the intersection of the signal traces 2xh can reduce the arrangement area of ​​the circuit modules 10a and the signal traces 2xh, thereby improving the light transmittance of the display light-transmitting area TA. In addition, by partially overlapping the sub-pixels 111 with the circuit modules 10a and partially overlapping the sub-pixels 111 with the signal traces 2xh, the light-transmitting area is increased, thereby improving the light transmittance of the display light-transmitting area TA.

[0126] The above provides a detailed description of a display panel and display device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
