Display panel and display device

Abstract

The application discloses a display panel and a display device. The substrate of the display panel comprises a first display area, a second display area and a third display area. The pixel density in the first display area can be set to be low to meet the light transmission requirement of the optical element, and a non-display area does not need to be set 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. In addition, the pixel density of the display pixels in the second display area decreases along a first direction, so as to solve the display split screen problem caused by the sudden change of the pixel density from the third display area to the first display area. Further, the aperture ratio of the display pixels in the second display area increases along the first direction, which is beneficial to ensuring that the current density of the display pixels in the area with low pixel density is not too high and avoiding the adverse effect of the high current density on the service life of the display pixels while ensuring the display brightness consistency of each area of the second display area.

Description

[0001] This application is a divisional application of the invention entitled "A Display Panel and Display Device", filed on September 30, 2020, with application number 202011062135.2. Technical Field

[0002] This application relates to the field of display technology, and more specifically, to a display panel and display device. Background Technology

[0003] With the continuous development of display technology, the screen ratio of display panels is getting higher and higher, moving towards a true "full screen". In this process, how to improve the screen ratio of display panels while retaining the placement of optical components such as front-facing cameras and brightness sensors has become an urgent problem to be solved.

[0004] In existing designs, optical components are often avoided by punching holes or slots in the front of the display. However, the areas punched or slotted cannot be used for display, which disrupts the overall consistency of the display panel and prevents the achievement of a true full-screen display. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a display panel and a display device to solve the problems of disrupting the overall consistency of the display panel and reducing the screen-to-body ratio caused by setting up non-display areas to avoid optical elements, while also solving the problem of obvious dividing lines appearing between the display area that transmits light to optical elements and adjacent display areas.

[0006] To achieve the above technical objectives, the embodiments of this application provide the following technical solutions:

[0007] A display panel, comprising:

[0008] The substrate includes a first display area, a second display area surrounding the first display area, and a third display area surrounding the second display area.

[0009] The first display area, the second display area, and the third display area each have multiple display pixels.

[0010] 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, wherein the first direction is the direction from the third display area to the first display area.

[0011] A display device includes a camera module and a display panel as described in any of the preceding claims;

[0012] The camera module is disposed on the side of the display panel away from the display direction, and the orthographic projection of the camera module onto the substrate of the display panel is located in the first display area.

[0013] As can be seen from the above technical solutions, the embodiments of this 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 to be relatively low in order to meet the light transmission 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, without the need to set a non-display area for the optical elements, which is beneficial to improving the screen ratio of the display panel and ensuring the overall consistency of the display panel.

[0014] Furthermore, the pixel density of the display pixels in the second display area decreases along the first direction to address the display splitting problem caused by the abrupt change in pixel density from the third display area to the first display area. Additionally, the aperture ratio of the display pixels in the second display area increases along the first direction. While ensuring consistent display brightness across all areas of the second display area, this helps prevent excessively high current density in areas with lower pixel density, thus avoiding adverse effects on the lifespan of the display pixels caused by excessively high current density.

[0031] As described in the background section, reference Figure 1 , Figure 1 This is a top view diagram of a display panel in the prior art. Existing designs typically create a light-transmitting area TH for optical components such as front-facing cameras by cutting holes or grooves in the front of the display screen. This allows the optical components to function normally using the light passing through this area TH. However, from... Figure 1 It is clear that these notches or holes cannot be used for display, which disrupts the overall consistency of the display panel. Furthermore, the presence of these notches or holes prevents the achievement of a true full-screen display.

[0032] To solve this problem, the inventors discovered through research that reducing the pixel density in a specific area of ​​the display panel could achieve the goal of allowing light to pass through the optical elements. However, practical application revealed that even after reducing the pixel density in a certain area, and increasing the brightness of that area by increasing the operating current to match the brightness of the normal display area, a jagged boundary line still appeared at the junction of that area and the normal display area, resulting in a phenomenon similar to... Figure 2 The issue shown is related to split-screen display. Figure 2 This is a diagram illustrating the split-screen phenomenon. Through further research, the inventors discovered that the phenomenon described above... Figure 2 The reason for the split-screen display problem shown is that the pixel density of the two display areas changes abruptly at the boundary, resulting in a noticeable split-screen phenomenon.

[0033] In view of this, the inventors, through further research, have provided a display panel whose substrate includes a first display area, a second display area, and a third display area. The pixel density in the first display area can be set to be relatively low to meet the light transmission requirements of the optical elements. This allows the optical elements located on the side of the first display area away from the display direction to operate normally using the light passing through the first display area, eliminating the need for a non-display area for the optical elements. This is beneficial for 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" display.

[0034] Furthermore, the pixel density of the display pixels in the second display area decreases along the first direction, while the aperture ratio of the display pixels in the second display area increases along the first direction, to solve the display splitting problem caused by the abrupt change in pixel density from the third display area to the first display area. Further, the increasing aperture ratio of the display pixels in the second display area, while ensuring consistent display brightness across all areas of the second display area, helps to prevent excessively high current density in areas with lower pixel density, thus avoiding adverse effects on the lifespan of the display pixels caused by excessively high current density.

[0035] The technical solutions of 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 of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This application provides a display panel, see reference. Figure 3 and Figure 4 , Figure 3 This is a top view schematic diagram of a display panel provided in an embodiment of this application. Figure 4 for Figure 3 An enlarged view of the area within the dashed frame K1, the display panel includes:

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

[0038] The first display area 11, the second display area 12 and the third display area 13 each have a plurality of display pixels (Pix).

[0039] The pixel density of the display pixel Pix in the second display area 12 decreases along the first direction, and the aperture ratio of the display pixel Pix in the second display area 12 increases along the first direction, where 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. The pixel density of the display pixels (Pix) in the third display area 13 is typically 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 to a lower value to increase the gap between adjacent display pixels (Pix), thereby increasing light transmittance, reducing light diffraction, and meeting the normal operation requirements of optical components such as camera modules or brightness sensors. Since the first display area 11 simultaneously has the functions of display and light transmission for optical components, it ensures the overall consistency of the display panel. Furthermore, since there is no need to set up a separate non-display area for optical components, it is beneficial to improve the screen-to-body ratio of the display panel, laying the foundation for achieving a true "full-screen" display.

[0041] Furthermore, in this embodiment, the pixel density of the display pixel Pix in the second display area 12 decreases along the first direction to solve the display split-screen problem caused by the abrupt change in 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 consistent display brightness in the second display area 12 and consistent display brightness with 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. This increases the brightness of a single display pixel Pix 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, it will lead to an increase in the current density of the display pixels Pix along the first direction. Excessive 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 consistent display brightness in all areas of the second display area 12, this helps to prevent excessively high current density in areas with lower pixel density, thus avoiding adverse effects on the lifespan of the display pixels Pix.

[0043] Based on the above embodiments, in one embodiment of this application, such as Figure 5 As shown, Figure 5 This is a partially enlarged schematic diagram of the display panel. The pixel shape of at least a portion of the display pixels Pix in the second display area 12 near the first display area 11 is the same as the pixel shape of the display pixels Pix in the first display area 11. The pixel shape of at least a portion of the display pixels Pix in the second display area 12 near 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 pixel Pix in the first display area 11 may be different from the pixel shape of the display pixel Pix in the third display area 13. That is, the pixel shape of the display pixel Pix in the first display area 11 may be set to a circular, trapezoidal, star-shaped, or other shapes to further reduce the diffraction of light and optimize the working effect of optical components, such as optimizing the imaging effect of the camera module. When the pixel shapes of the display pixel Pix in the first display area 11 and the display pixel Pix in the third display area 13 are different, the pixel shape of the display pixel Pix in the second display area 12 also gradually changes along the first direction. This helps to further weaken the display splitting phenomenon caused by changes in pixel density and pixel shape, thereby ensuring the display consistency and continuity of the first display area 11, the second display area 12, and the third display area 13.

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

[0046] The N display sub-regions 121 are arranged sequentially along the first direction, and are numbered from 1 to N from the display sub-region 121 adjacent to the third display area 13 to the display sub-region 121 adjacent to the first display area 11. Figure 6 In the text, 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-regions. At this time, the pixel density and aperture ratio of the display pixels Pix in each display sub-region can be the same, as long as the second display area 12 satisfies the condition that the pixel density decreases in the first direction and the aperture ratio increases. That is, the pixel density of the display pixels Pix in the display sub-regions numbered 1 to N decreases and the aperture ratio of the display pixels Pix in the display sub-regions numbered 1 to N increases.

[0048] The display pixels Pix in each display sub-region are identical (aperture ratio and pixel density), which allows the display pixels Pix in the same display sub-region to be mass-produced, which helps to simplify the manufacturing process of the display pixels Pix in the second display area 12.

[0049] Based on the above embodiments, in another embodiment of this application, reference is made to... Figure 7 , Figure 7 This is a partially enlarged schematic diagram of the display panel. 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] The display sub-area 121, numbered 1, also contains a plurality of non-light-emitting pixels Pix1, which are in a non-working state during the display phase of the display panel.

[0051] This embodiment provides a feasible way to reduce the pixel density of the display sub-region 121 numbered 1. Specifically, the pixel density of the display sub-region 121 numbered 1 is reduced by setting multiple non-light-emitting pixels Pix1. Other display pixels Pix normally used for light emission can be prepared in the same process as the display pixels Pix in the third display area 13, simplifying the preparation process of the display sub-region 121 numbered 1, and thus simplifying the preparation process of the second display area 12.

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

[0053] A plurality of pixel circuits 20 are located between the substrate 10 and the display pixel Pix, the pixel circuits 20 being used to drive the display pixel Pix to work.

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

[0055] The pixel circuit 20 can be a 7T1C pixel circuit 20 or a 2T1C pixel circuit 20. This application does not limit the specific type of the pixel circuit 20. A thin-film transistor is directly connected to the display pixel Pix within the pixel circuit 20. Figure 8 The diagram also shows an insulating layer 30 located between the pixel circuit 20 and the display pixel 20 and the non-light-emitting pixel 21, as well as a via 31 penetrating the insulating layer 30. The via 31 is filled with conductive material to achieve electrical connection between the pixel circuit 20 and the display pixel Pix.

[0056] from Figure 8 As can be seen, the pixel circuit 20 is electrically connected to the display pixel Pix, which is normally used for light emission, through a via 31. However, there is no via between the pixel circuit 20 and the anode of the non-light-emitting pixel Pix1, making the anode of the non-light-emitting pixel Pix1 insulated from all the pixel circuits 20. Figure 8 It is not difficult to see that in the implementation scheme of the non-light-emitting pixel Pix1 provided in this embodiment, only the process of preparing the via 31 needs to be improved. That is, no hole is made in the insulating layer 30 at the location of the non-light-emitting pixel Pix1, and no other process needs to be improved, which helps to simplify the preparation process of the non-light-emitting pixel Pix1.

[0057] Based on the above embodiments, in one embodiment of this application, reference is made to... Figure 9 , Figure 9 This is a partially 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 can be slightly less than the pixel density of the third display area 13. At this time, it is necessary to increase the brightness of a single display pixel Pix in the display sub-region 121 numbered 1 to make the brightness of the display sub-region 121 numbered 1 consistent with the brightness of the third display area 13. The way to increase the brightness of a single display pixel Pix in the display sub-region 121 numbered 1 is usually to increase the current supplied to the display pixel Pix in that region. To prevent the current density of the display pixel Pix in that region from increasing due to the increased current, this embodiment uses a method where the brightness of the display sub-region 121 numbered 1... The aperture ratio of the display pixel Pix in the display sub-region 121 is greater than that of the display pixel Pix in the third display area 13, so that the current density of the display pixel Pix in the display sub-region 121 numbered 1 is approximately equal to that of the display pixel Pix in the third display area 13. This avoids a large difference in the lifespan of the display pixel Pix in the display sub-region 121 numbered 1 and the display pixel Pix in the third display area 13 due to a large current density.

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

[0060] Optionally, the aperture ratio of the display pixel Pix in the display sub-region 121 numbered N can be equal to the aperture ratio of the display pixel 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. This allows the display pixel Pix in the display sub-region 121 numbered N to be fabricated together with the display pixel Pix in the first display area 11 in the same process, which simplifies the fabrication process of the second display area 12.

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

[0062] The pixel shape of the first type of 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 of pixel Pix3 is the same as the pixel shape of the display pixel Pix in the third display area 13.

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

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

[0066] exist Figure 10 and Figure 11 In this embodiment, the first type of pixel Pix2 has the same shape as the display pixels in the first display area 11. In other embodiments of this application, refer to... Figure 12 , Figure 12 This is a partially 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 that transition from rectangles to the display pixel shapes in the first display area 11.

[0067] Generally, the shape of a display pixel (Pix) is mainly determined by the anode shape of the display pixel (Pix). That is, the anode shape of the first type of pixel (Pix2) is a preset pattern, which includes at least one of a circle, a triangle, and a rhombus. These non-rectangular shapes, such as circles, triangles, and rhombuses, help reduce the diffraction of light caused by the gaps between adjacent display pixels (Pix), and help improve the working performance of optical components (such as camera modules).

[0068] For the display pixels Pix in the first display area 11, in order to better improve the light transmission performance between 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 gaps for light to pass through.

[0069] Based on the above embodiments, in another embodiment of this application, such as Figure 13 As shown, Figure 13 The diagram shows a cross-sectional view of the display panel. The display panel further includes a plurality of pixel circuits 20 located between the substrate 10 and the display pixel Pix, the pixel circuits 20 being used to drive the display pixel Pix to work.

[0070] The plurality of pixel circuits 20 are distributed in the second display area 12 and the third display area 13. The portion 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 work.

[0071] exist Figure 13 For clarity, only cross-sectional views of the first display area 11 and the second display area 12 are shown. Furthermore, Figure 13 An insulating layer 30 located between the pixel circuit 20 and the display pixel Pix is ​​also shown, as well as a via 31 penetrating the insulating layer 30.

[0072] In this embodiment, the pixel circuits 20 used to drive the display pixels Pix in the first display area 11 are all disposed in the second display area 12, that is, the first display area 11 does not have pixel circuits 20 or other structures, so as to improve the light transmittance of the first display area 11.

[0073] Based on the above embodiments, in another embodiment of this application, such as Figure 14 As shown, Figure 14 The diagram shows a cross-sectional view of the display panel. The display panel further includes a plurality of pixel circuits 20 located between the substrate 10 and the display pixel Pix, the pixel circuits 20 being used to drive the display pixel Pix to work.

[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 light transmittance of the first display area 11 and improving the working environment of the optical components.

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

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

[0079] Accordingly, embodiments of this application also provide a display device, such as... Figure 15 As shown, Figure 15 This is a schematic diagram of the appearance of the display device 100, which includes optical elements and a display panel as described in any of the above embodiments.

[0080] The optical elements include, but are not limited to, at least one of a camera module and a brightness sensor.

[0081] In summary, the embodiments of this 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. The pixel density in the first display area can be set to be relatively low to meet the light transmission 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 without setting a non-display area for the optical elements, which is beneficial to improving the screen ratio of the display panel and ensuring the overall consistency of the display panel.

[0082] Furthermore, the pixel density of the display pixels in the second display area decreases along the first direction to address the display splitting problem caused by the abrupt change in pixel density from the third display area to the first display area. Additionally, the aperture ratio of the display pixels in the second display area increases along the first direction. While ensuring consistent display brightness across all areas of the second display area, this helps prevent excessively high current density in areas with lower pixel density, thus avoiding adverse effects on the lifespan of the display pixels caused by excessively high current density.
