[0031] As mentioned in the background technology, Figure 1 , Figure 1 This is a top view of a display panel in the prior art. In order to set up optical elements such as a front camera, the prior art usually digs holes or grooves on the front of the display screen to leave a light-transmitting area TH for the optical element, so that the optical element can use the light passing through the light-transmitting area TH to work normally. Figure 1 It can be clearly seen that these grooves or holes cannot be used for display, which destroys the overall consistency of the display panel, and due to the existence of grooves or holes, a true full screen cannot be achieved.

[0032] To solve this problem, the inventors discovered through research that the purpose of optical element light transmission can be achieved by reducing the pixel density in a certain area of ​​the display panel. However, in actual application, it was found that after reducing the pixel density in a certain area, even if the brightness of the area was increased by increasing the operating current to make the brightness of the area consistent with that of the normal display area, a jagged boundary line would still appear at the junction of the area and the normal display area, that is, Figure 2 The problem of display split screen is shown. Figure 2 The present invention further studies and finds that the following Figure 2 The reason for the display split-screen problem shown is that the pixel density of the two display areas suddenly changes at the junction, resulting in an obvious split-screen phenomenon.

[0033] In view of this, the inventors have provided a display panel through further research, wherein the substrate of the display panel includes a first display area, a second display area and a third display area, wherein the pixel density in the first display area can be set lower to meet the light transmittance requirements of the optical elements, so that the optical elements located on the side of the first display area away from the display direction can use the light passing through the first display area to work normally, and there is no need to set a non-display area for the optical elements, which is conducive to improving the screen-to-body ratio of the display panel, ensuring the overall consistency of the display panel, and laying the foundation for the display panel to achieve a true "full screen".

[0034] In addition, the pixel density of the display pixels in the second display area decreases along the first direction, and the aperture ratio of the display pixels in the second display area increases along the first direction, thereby resolving the display split-screen problem caused by the sudden change in pixel density from the third display area to the first display area. Furthermore, the aperture ratio of the display pixels in the second display area increases along the first direction. While ensuring consistent display brightness across the second display area, this helps ensure that the current density of the display pixels in areas with lower pixel density is not too high, thereby avoiding the adverse effects of excessive current density on the lifespan of the display pixels.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] The present application embodiment provides a display panel, referring to Figure 3 and Figure 4 , Figure 3 This is a schematic top view of a display panel provided in an embodiment of the present application. Figure 4 for Figure 3 An enlarged schematic diagram of the dotted line frame K1 area, wherein the display panel includes:

[0037] The substrate 10 includes a first display area 11 , a second display area 12 located around the first display area 11 , and a third display area 13 located around the second display area 12 .

[0038] A plurality of display pixels Pix are distributed in each of the first display area 11 , the second display area 12 and the third display area 13 .

[0039] The pixel density of the display pixels Pix in the second display area 12 decreases along a first direction, and the aperture ratio of the display pixels Pix in the second display area 12 increases along the first direction. The first direction is the direction from the third display area 13 to the first display area 11.

[0040] In this embodiment, the third display area 13 is the normal display area, and the pixel density of the display pixels Pix in the third display area 13 is generally high to meet the user's requirements for a good display effect in the normal display area. The pixel density of the display pixels Pix in the first display area 11 can be set lower to increase the gap between adjacent display pixels Pix, thereby increasing light transmittance, reducing light diffraction, and meeting the normal working requirements of optical elements such as camera modules or brightness sensors. Since the first display area 11 has the functions of displaying and transmitting light to optical elements at the same time, the overall consistency of the display panel is guaranteed, and since there is no need to set a separate non-display area for the optical elements, it is conducive to improving the screen-to-body ratio of the display panel, laying the foundation for achieving a true "full screen".

[0041] In addition, in this embodiment, the pixel density of the display pixels Pix in the second display area 12 decreases along the first direction to solve the display split screen problem caused by the sudden change of pixel density from the third display area 13 to the first display area 11.

[0042] Furthermore, since the pixel density in the second display area 12 decreases along the first direction, in order to ensure that the display brightness of the second display area 12 is consistent and consistent with the display brightness of the third display area 13, the operating current provided to the display pixels Pix in the second display area 12 increases along the first direction, so that the brightness of each display pixel Pix increases along the first direction, compensating for the brightness loss caused by the decrease in pixel density along the first direction. However, if the aperture ratio of the display pixels Pix in the second display area 12 is consistent, the current density of the display pixels Pix will increase along the first direction, and excessively high current density will adversely affect the lifespan of the display pixels Pix. Therefore, in this embodiment, the aperture ratio of the display pixels Pix in the second display area 12 increases along the first direction. While ensuring the consistency of the display brightness of each area of ​​the second display area 12, it is beneficial to ensure that the current density of the display pixels Pix in areas with lower pixel density is not too high, thereby avoiding the adverse effect of excessive current density on the lifespan of the display pixels Pix.

[0043] Based on the above embodiments, in one embodiment of the present application, Figure 5 As shown, Figure 5 This is a partially enlarged schematic diagram of the display panel. The pixel shape of at least some of the display pixels Pix in the second display area 12 close to the first display area 11 is the same as the pixel shape of the display pixels Pix in the first display area 11, and the pixel shape of at least some of the display pixels Pix in the second display area 12 close to the third display area 13 is the same as the pixel shape of the display pixels Pix in the third display area 13.

[0044] In this embodiment, the pixel shape of the display pixels Pix in the first display area 11 can be different from the pixel shape of the display pixels Pix in the third display area 13. That is, the pixel shape of the display pixels Pix in the first display area 11 can be set to a circular, trapezoidal, star-shaped, or other shape to further reduce the diffraction phenomenon of light, which is conducive to optimizing the working effect of optical components, such as optimizing the imaging effect of the camera module. In the case where the pixel shape of the display pixels Pix in the first display area 11 is different from that of the display pixels Pix in the third display area 13, the pixel shape of the display pixels Pix in the second display area 12 also gradually changes along the first direction, which is conducive to further reducing the display split screen phenomenon caused by changes in pixel density and pixel shape, thereby ensuring the display consistency and coherence of the first display area 11, the second display area 12, and the third display area 13.

[0045] Based on the above embodiment, in another embodiment of the present application, Figure 6 As shown, Figure 6is an enlarged schematic diagram of the second display area 12 . The second display area 12 includes N display sub-areas 121 , where N is greater than or equal to 2.

[0046] The N display sub-areas 121 are arranged in sequence along the first direction, and are numbered from 1 to N in sequence from the display sub-area 121 adjacent to the third display area 13 to the display sub-area 121 adjacent to the first display area 11. Figure 6 In FIG. 1 , the number of the display sub-region 121 is marked below the display sub-region 121 .

[0047] In this embodiment, the second display area 12 is divided into at least two display sub-areas. At this time, the pixel density and aperture ratio of the display pixels Pix in each display sub-area can be the same, as long as the second display area 12 satisfies the decreasing pixel density and increasing aperture ratio in the first direction, that is, the pixel density of the display pixels Pix in the display sub-areas numbered 1 to N decreases, and the aperture ratio of the display pixels Pix in the display sub-areas numbered 1 to N increases.

[0048] The display pixels Pix in each display sub-region are the same (aperture ratio and pixel density), so that the display pixels Pix in the same display sub-region can be manufactured in batches, which is beneficial to simplifying the manufacturing process of the display pixels Pix in the second display area 12 .

[0049] On the basis of the above embodiment, in another embodiment of the present application, reference Figure 7 , Figure 7 is a partial enlarged schematic diagram of the display panel, in which the aperture ratio of the display pixel Pix in the display sub-region 121 numbered 1 is equal to the aperture ratio of the display pixel Pix in the third display area 13;

[0050] A plurality of non-luminescent pixels Pix1 are distributed in the display sub-region 121 numbered 1. The non-luminescent pixels Pix1 are in a non-working state during the display phase of the display panel.

[0051] This embodiment provides a feasible method for specifically reducing the pixel density of the display sub-region 121 numbered 1, that is, the pixel density of the display sub-region 121 is reduced by setting a plurality of non-luminous pixels Pix1 in the display sub-region 121, while other display pixels Pix normally used for luminescence can be prepared in the same process as the display pixels Pix in the third display area 13, thereby simplifying the preparation process of the display sub-region 121 numbered 1, and further simplifying the preparation process of the second display area 12.

[0052] Specifically, refer to Figure 8 , Figure 8 The cross-sectional structure diagram of the second display area 12 is shown, and the display panel further includes:

[0053] A plurality of pixel circuits 20 are located between the substrate 10 and the display pixels Pix. The pixel circuits 20 are used to drive the display pixels Pix to operate.

[0054] The anode of the non-luminescent pixel Pix1 is insulated from all the pixel circuits 20 .

[0055] The pixel circuit 20 may be a 7T1C pixel circuit 20 or a 2T1C pixel circuit 20. The present application does not limit the specific type of the pixel circuit 20. A thin film transistor in the pixel circuit 20 is directly connected to the display pixel Pix. Figure 8 Also shown are an insulating layer 30 located between the pixel circuit 20 and the display pixel 20 and the non-luminous pixel 21, and a via 31 penetrating the insulating layer 30. The via 31 is filled with a conductive material to achieve electrical connection between the pixel circuit 20 and the display pixel Pix.

[0056] from Figure 8 It can be seen that the pixel circuit 20 is electrically connected to the normally luminous display pixel Pix through the via 31, while there is no via between the pixel circuit 20 and the anode of the non-luminous pixel Pix1, so that the anode of the non-luminous pixel Pix1 is insulated from all the pixel circuits 20. Figure 8 It is not difficult to see that in the implementation scheme of the non-luminous pixel Pix1 provided in this embodiment, only the process of preparing the via 31 needs to be improved, that is, the insulating layer 30 is not punched at the position where the non-luminous pixel Pix1 is located, and there is no need to improve other processes, which is conducive to simplifying the preparation process of the non-luminous pixel Pix1.

[0057] Based on the above embodiments, in one embodiment of the present application, reference is made to Figure 9 , Figure 9 1 is a partial enlarged schematic diagram of the display panel. The aperture ratio of the display pixel Pix in the display sub-region 121 numbered 1 is greater than the aperture ratio of the display pixel Pix in the third display area 13 .

[0058] In this embodiment, the pixel density of the display sub-region 121 numbered 1 may be slightly lower than the pixel density of the third display region 13. In this case, the brightness of a single display pixel Pix in the display sub-region 121 numbered 1 needs to be increased to ensure that the brightness of the display sub-region 121 numbered 1 is consistent with the brightness of the third display region 13. The brightness of a single display pixel Pix in the display sub-region 121 numbered 1 is generally increased by increasing the current provided to the display pixel Pix in the region. To prevent the current density of the display pixel Pix in the region from increasing due to the increase in current, in this embodiment, the aperture ratio of the display pixel Pix in the display sub-region 121 numbered 1 is made greater than the aperture ratio of the display pixel Pix in the third display region 13. This ensures that the current density of the display pixel Pix in the display sub-region 121 numbered 1 is approximately equal to the current density of the display pixel Pix in the third display region 13, thereby preventing a large difference in the lifespan of the display pixel Pix in the display sub-region 121 numbered 1 and the lifespan of the display pixel Pix in the third display region 13 due to the larger current density.

[0059] Similarly, the pixel density of the display sub-areas 121 numbered 2, 3...N gradually decreases. In order to maintain consistent brightness, the current provided to the display pixels Pix in the display sub-areas 121 numbered 2, 3...N gradually increases. In order to maintain a relatively consistent lifespan of the display pixels Pix in each display sub-area 121 or maintain the current density of the display pixels Pix in each display sub-area 121 during operation, and to avoid abnormal attenuation of the lifespan of the display pixels Pix due to excessive current density, the aperture ratio of the display pixels Pix in the display sub-areas 121 numbered 2, 3...N gradually increases.

[0060] Optionally, the aperture ratio of the display pixels Pix in the display sub-region 121 numbered N can be equal to the aperture ratio of the display pixels Pix in the first display area 11. In this case, the pixel density of the display sub-region 121 numbered N can also be equal to the pixel density of the first display area 11. In this way, the display pixels Pix in the display sub-region 121 numbered N can be manufactured together with the display pixels Pix in the first display area 11 in the same process, which helps to simplify the manufacturing process of the second display area 12.

[0061] Based on the above embodiment, in another embodiment of the present application, Figure 10 and Figure 11 As shown, Figure 10 and Figure 11This is a partial enlarged schematic diagram of the display panel, in which the display sub-area 121 numbered j includes first-type pixels Pix2 and second-type pixels Pix3 alternately arranged along the second direction; 1≤j<N; the second direction includes the horizontal direction or the vertical direction.

[0062] The pixel shape of the first type pixel Pix2 is the same as the pixel shape of the display pixel Pix in the first display area 11 .

[0063] The pixel shape of the second-type pixel Pix3 is the same as the pixel shape of the display pixel Pix in the third display area 13 .

[0064] The display pixels Pix in the display sub-regions 121 with numbers greater than j are all the first-type pixels Pix2.

[0065] In this embodiment, the display pixels Pix in the display sub-region 121 numbered j include pixels of two pixel shapes, namely, first-type pixels Pix2 and second-type pixels Pix3. The display pixels Pix in the display sub-regions 121 numbered greater than j are all first-type pixels Pix2, while the display pixels Pix in the display sub-regions 121 numbered less than j are all second-type pixels Pix3. That is, the display sub-region 121 numbered j exists as a transition zone for the pixel shapes of the display pixels Pix, which helps to avoid subtle display differences that may be caused by sudden changes in pixel shape and optimizes the display effect of the second display region 12. Figure 10 In the embodiment, the second direction is the vertical direction. Figure 11 , the second direction is a horizontal direction.

[0066] exist Figure 10 and Figure 11 In the embodiment, the first type of pixel Pix2 has the same shape as the display pixel in the first display area 13. In other embodiments of the present application, refer to Figure 12 , Figure 12 This is a partial enlarged schematic diagram of the display panel. The pixel shape of the first type of pixel Pix2 can also be other polygons, such as regular pentagons, regular hexagons, etc., which are shapes transitioning from rectangles to the display pixel shape in the first display area 11.

[0067] Generally, the shape of a display pixel Pix is ​​primarily determined by the shape of its anode. Specifically, the anode shape of the first-type pixel Pix2 is a preset pattern, which includes at least one of a circle, a triangle, and a diamond. Non-rectangular shapes such as circles, triangles, and diamonds help reduce light diffraction caused by gaps between adjacent display pixels Pix, thereby improving the performance of optical components (e.g., camera modules).

[0068] For the display pixels Pix in the first display area 11, in order to better improve the light transmittance performance between the display pixels Pix, the cathode shape of the display pixels Pix in the first display area 11 is also the preset pattern, and the cathodes of adjacent display pixels Pix in the first display area 11 do not contact each other, leaving a gap for light to pass through.

[0069] On the basis of the above embodiment, in another embodiment of the present application, Figure 13 As shown, Figure 13 is a schematic diagram of the cross-sectional structure of the display panel. The display panel further includes: a plurality of pixel circuits 20 located between the substrate 10 and the display pixels Pix. The pixel circuits 20 are used to drive the display pixels Pix to operate.

[0070] The plurality of pixel circuits 20 are distributed in the second display area 12 and the third display area 13 . Part of the pixel circuits 20 distributed in the second display area 12 is used to drive the display pixels Pix located in the first display area 11 to operate.

[0071] exist Figure 13 For the sake of clarity, only the cross-sectional schematic diagram of the first display area 11 and the second display area 12 is shown. Figure 13 Also shown are an insulating layer 30 located between the pixel circuit 20 and the display pixel Pix, and a via hole 31 penetrating the insulating layer 30 .

[0072] In this embodiment, the pixel circuits 20 for driving the display pixels Pix in the first display area 11 are all arranged in the second display area 12, that is, the pixel circuits 20 and other structures are not arranged in the first display area 11 to improve the transmittance of the first display area 11.

[0073] On the basis of the above embodiment, in another embodiment of the present application, Figure 14 As shown, Figure 14 is a schematic diagram of the cross-sectional structure of the display panel. The display panel further includes: a plurality of pixel circuits 20 located between the substrate 10 and the display pixels Pix. The pixel circuits 20 are used to drive the display pixels Pix to operate.

[0074] The plurality of pixel circuits 20 are distributed in the first display area 11 , the second display area 12 and the third display area 13 .

[0075] The pixel circuits 20 distributed in the first display area 11 are electrically connected to at least two display pixels Pix in the first display area 11 .

[0076] In this embodiment, the pixel circuits 20 distributed in the first display area 11 are electrically connected to at least two display pixels Pix in the first display area 11, that is, in the first display area 11, one pixel circuit 20 is used to drive at least two display pixels Pix, so as to reduce the number of pixel circuits 20 in the first display area 11, thereby improving the transmittance of the first display area 11 and improving the working environment of the optical element.

[0077] Similarly, in Figure 14 For the sake of clarity, only the cross-sectional view of the first display area 11 is shown. Figure 14 , an insulating layer 30 located between the pixel circuit 20 and the display pixel Pix, and a via hole 31 penetrating the insulating layer 30 are also shown.

[0078] Optionally, the pixel circuits 20 distributed in the first display area 11 are electrically connected to at least two display pixels Pix that emit light of the same color.

[0079] Accordingly, the embodiment of the present application further provides a display device, such as Figure 15 As shown, Figure 15 is a schematic diagram of the appearance of the display device 100 , which includes an optical element and a display panel as described in any of the above embodiments.

[0080] The optical element includes but is not limited to at least one of a camera module and a brightness sensor.

[0081] In summary, the embodiments of the present application provide a display panel and a display device, wherein the substrate of the display panel includes a first display area, a second display area, and a third display area, wherein the pixel density in the first display area can be set lower to meet the light transmittance requirements of the optical element, so that the optical element located on the side of the first display area away from the display direction can use the light passing through the first display area to work normally, without setting a non-display area for the optical element, which is beneficial to improving the screen-to-body ratio of the display panel and ensuring the overall consistency of the display panel.

[0082] In addition, the pixel density of the display pixels in the second display area decreases along the first direction to solve the display split-screen problem caused by the sudden change in pixel density from the third display area to the first display area. Furthermore, the aperture ratio of the display pixels in the second display area increases along the first direction. While ensuring the consistency of display brightness across the various areas of the second display area, it is beneficial to ensure that the current density of the display pixels in the areas with lower pixel density is not too high, thereby avoiding the adverse effects of excessive current density on the life of the display pixels.
