Detailed Description
As described in the background art, referring to fig. 1, fig. 1 is a schematic top view of a display panel in the prior art, and in order to provide an optical element such as a front camera, a light-transmitting area TH is usually reserved for the optical element by digging a hole or a groove in the front of the display screen, so that the optical element can normally operate by using light transmitted through the light-transmitting area TH. However, as is apparent from fig. 1, these cut-out or cut-out regions cannot be used for display, which deteriorates the overall uniformity of the display panel, and a full screen cannot be realized in a true sense due to the presence of the cut-out or cut-out regions.
In order to solve this problem, the inventors have found through studies that the object of transmitting light through the optical element can be achieved by reducing the pixel density in a certain region of the display panel. However, it is found through practical applications that after the pixel density of a certain region is reduced, even if the luminance of the region is increased by increasing the operating current, so that the luminance of the region is consistent with that of the normal display region, a jagged boundary phenomenon may still occur at a boundary between the region and the normal display region, that is, a problem of display split as shown in fig. 2 is caused, where fig. 2 is a schematic diagram of the display split phenomenon. The inventor finds through further research that the display split problem shown in fig. 2 is caused by abrupt changes in pixel density of two display areas at the intersection, thereby causing a significant split phenomenon.
In view of the above, through further research, the inventor provides a display panel, where a substrate of the display panel includes a first display area, a second display area, and a third display area, where the pixel density in the first display area may be set to be lower to meet the requirement of light transmission of an optical element, so that the optical element located on a side of the first display area away from a display direction may normally operate by using light passing through the first display area, and a non-display area does not need to be set for the optical element, which is beneficial to improving a screen occupation ratio of the display panel, ensures the overall uniformity of the display panel, and lays a foundation for realizing a truly 'full screen' for the display panel.
In addition, the pixel density of the display pixels in the second display area is decreased progressively along the first direction, and the aperture ratio of the display pixels in the second display area is increased progressively along the first direction, so that the problem of display split caused by abrupt change of the pixel density from the third display area to the first display area is solved. Furthermore, the aperture opening ratio of the display pixels in the second display area is increased progressively along the first direction, so that the current density of the display pixels in the area with lower pixel density is not too high under the condition of ensuring the uniformity of the display brightness of each area of the second display area, and the adverse effect of the too high current density on the service life of the display pixels is avoided.
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
An embodiment of the present application provides a display panel, and referring to fig. 3 and fig. 4, fig. 3 is a schematic top view of the display panel provided in the embodiment of the present application, and fig. 4 is an enlarged schematic view of a dashed-line frame K1 region in fig. 3, where the display panel includes:
a substrate 10, the substrate 10 comprising 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.
The first display area 11, the second display area 12, and the third display area 13 are distributed with a plurality of display pixels Pix.
The pixel density of the display pixels Pix in the second display area 12 decreases progressively along the first direction, the aperture ratio of the display pixels Pix in the second display area 12 increases progressively along the first direction, and the first direction is a direction in which the third display area 13 points to the first display area 11.
In this embodiment, the third display area 13 is a normal display area, and the pixel density of the display pixels Pix in the third display area 13 is usually higher, so as to meet the requirement of the user on a good display effect of the normal display area. The pixel density of the display pixels Pix in the first display area 11 can be set to be lower so as to increase the gap between the adjacent display pixels Pix, thereby increasing the light transmittance, reducing the light diffraction, and meeting the normal working requirements of optical elements such as a camera module or a brightness sensor. Because the first display area 11 has possessed the demonstration simultaneously and for optical element printing opacity's function, guaranteed display panel's whole uniformity, and owing to need not to set up non-display area alone for optical element, be favorable to improving display panel's screen to account for the ratio, establish the basis for realizing real "full face screen".
In addition, in the present embodiment, the pixel density of the display pixels Pix in the second display region 12 decreases in the first direction, so as to solve the problem of display split caused by the abrupt change of the pixel density from the third display region 13 to the first display region 11.
Further, since the pixel density of the pixel density in the second display area 12 decreases along the first direction, in order to ensure that the display luminance of the second display area 12 is consistent and is consistent with the display luminance 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 luminance of the single display pixel Pix increases along the first direction, and the luminance loss caused by the decrease of the pixel density along the first direction is compensated. However, if the aperture ratios of the display pixels Pix in the second display area 12 are the same, the current density of the display pixels Pix increases along the first direction, and the lifetime of the display pixels Pix is adversely affected due to the excessively high current density. Therefore, in this embodiment, the aperture ratio of the display pixels Pix in the second display area 12 increases progressively along the first direction, which is beneficial to ensuring that the current density of the display pixels Pix in the area with lower pixel density is not too high under the condition of ensuring the uniformity of the display brightness of each area of the second display area 12, and avoiding the adverse effect of the too high current density on the service life of the display pixels Pix.
On the basis of the above embodiments, as shown in fig. 5, in an embodiment of the present application, fig. 5 is a partially enlarged schematic view of a display panel, a pixel shape of at least a portion of the display pixels Pix in the second display area 12 close to the first display area 11 is the same as a pixel shape of the display pixels Pix in the first display area 11, and a pixel shape of at least a portion of the display pixels Pix in the second display area 12 close to the third display area 13 is the same as a pixel shape of the display pixels Pix in the third display area 13.
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 be a circle, a trapezoid, a star, or the like, so as to further reduce the diffraction phenomenon of light, which is beneficial to optimizing the working effect of the optical element, for example, optimizing the imaging effect of the camera module. And in the case that the pixel shapes of the display pixels Pix in the first display area 11 and the display pixels Pix in the third display area 13 are different, the pixel shapes of the display pixels Pix in the second display area 12 are also gradually changed along the first direction, which is beneficial to further weakening the display split phenomenon caused by the change of the pixel density and the pixel shapes, thereby ensuring the display consistency and the continuity of the first display area 11, the second display area 12 and the third display area 13.
On the basis of the above embodiments, in another embodiment of the present application, as shown in fig. 6, fig. 6 is an enlarged schematic view of the second display area 12, where the second display area 12 includes N display sub-areas 121, and N is greater than or equal to 2.
The N display sub-regions 121 are sequentially arranged along the first direction, and are numbered sequentially from 1 to N from the display sub-region 121 adjacent to the third display region 13 to the display sub-region 121 adjacent to the first display region 11. In fig. 6, the number of the display sub-area 121 is indicated below the display sub-area 121.
In this embodiment, the second display area 12 is divided into at least two display sub-areas, and the pixel density and the aperture ratio of the display pixels Pix in each display sub-area may be the same, as long as the second display area 12 is made to satisfy that the pixel density decreases and the aperture ratio increases in the first direction, that is, the pixel density of the display pixels Pix in the display sub-areas numbered from 1 to N decreases and the aperture ratio of the display pixels Pix in the display sub-areas numbered from 1 to N increases.
The display pixels Pix in each display sub-region are identical (aperture ratio and pixel density), so that the display pixels Pix in the same display sub-region can be manufactured in batch, which is advantageous for simplifying the manufacturing process of the display pixels Pix in the second display region 12.
On the basis of the above embodiment, in another embodiment of the present application, referring to fig. 7, fig. 7 is a partially enlarged schematic view of a display panel, and the aperture ratio of the display pixels Pix of the display sub-region 121 numbered 1 is equal to the aperture ratio of the display pixels Pix in the third display region 13;
a plurality of non-light emitting pixels Pix1 are further distributed in the display sub-region 121 numbered 1, and the non-light emitting pixels Pix1 are in a non-working state at the display stage of the display panel.
The embodiment provides a feasible way of specifically reducing the pixel density of the display sub-region 121 with the number of 1, that is, the pixel density of the display sub-region 121 is reduced by arranging a plurality of non-light emitting pixels Pix1 in the display sub-region 121 with the number of 1, and 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 region 13, so that the preparation process of the display sub-region 121 with the number of 1 is simplified, and the preparation process of the second display region 12 is further simplified.
Specifically, referring to fig. 8, fig. 8 shows a schematic cross-sectional structure diagram of the second display area 12, and the display panel further includes:
and the pixel circuits 20 are positioned between the substrate 10 and the display pixels Pix, and the pixel circuits 20 are used for driving the display pixels Pix to work.
The anode of the non-emitting pixel Pix1 is insulated from all the pixel circuits 20.
The pixel circuit 20 may be a 7T1C pixel circuit 20, or may be a 2T1C pixel circuit 20, and the specific type of the pixel circuit 20 is not limited in this application. Directly connected to the display pixels Pix is a thin film transistor in the pixel circuit 20. Fig. 8 also shows an insulating layer 30 between the pixel circuit 20 and the display pixel 20 and the non-emitting pixel 21, and a via 31 penetrating the insulating layer 30, wherein the via 31 is filled with a conductive material to electrically connect the pixel circuit 20 and the display pixel Pix.
As can be seen from fig. 8, the pixel circuit 20 is electrically connected to the display pixel Pix normally used for emitting light through the via 31, and there is no via between the pixel circuit 20 and the anode of the non-emitting pixel Pix1, so that the anode of the non-emitting pixel Pix1 is insulated from all the pixel circuits 20. As can be seen from fig. 8, in the implementation scheme of the non-emissive pixel Pix1 provided in this embodiment, only the process of preparing the via hole 31 needs to be improved, that is, the insulating layer 30 is not punched at the position of the non-emissive pixel Pix1, and other processes do not need to be improved, which is beneficial to simplifying the preparation process of the non-emissive pixel Pix 1.
On the basis of the above embodiments, in an embodiment of the present application, referring to fig. 9, fig. 9 is a partially enlarged schematic view of the display panel, and the aperture ratio of the display pixels Pix in the display sub-region 121 numbered 1 is greater than the aperture ratio of the display pixels Pix in the third display region 13.
In this embodiment, the pixel density of the display sub-region 121 numbered 1 may be slightly smaller than the pixel density of the third display region 13, at this time, the luminance of a single display pixel Pix in the display sub-region 121 numbered 1 needs to be increased to make the luminance of the display sub-region 121 numbered 1 consistent with the luminance of the third display region 13, and the manner of increasing the luminance of the single display pixel Pix in the display sub-region 121 numbered 1 is generally to increase the magnitude of the current provided to the display pixel Pix in this region, so that the current density of the display pixel Pix in this region is not increased due to the increase of the current, in this embodiment, 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 by making the aperture ratio of the display pixel Pix in the display sub-region 121 numbered 1 greater than the aperture ratio of the display pixel Pix in the third display region 13, so as to avoid the difference between the lifetime of the display pixel Pix in the display sub-region 121 numbered 1 and the lifetime of the display pixel Pix in the third display region 13 caused by the greater current density.
Similarly, the pixel density of the display sub-region 121 numbered 2, 3 … … N is gradually decreased, the current supplied to the display pixels Pix in the display sub-region 121 numbered 2, 3 … … N is gradually increased in order to maintain uniform brightness, and the aperture ratio of the display pixels Pix in the display sub-region 121 numbered 2, 3 … … N is gradually increased in order to maintain relatively uniform lifetime of the display pixels Pix in each display sub-region 121 or maintain the current density of the display pixels Pix in each display sub-region 121 during operation, and to avoid abnormal attenuation of the lifetime of the display pixels Pix due to excessive current density.
Alternatively, the aperture ratio for the display pixels Pix in the display sub area 121 numbered N may be equal to the aperture ratio for the display pixels Pix in the first display area 11. The pixel density of the display sub-region 121 numbered N may also be equal to the pixel density of the first display region 11. In this way, the display pixels Pix in the display sub-region 121 with the number N can be prepared together with the display pixels Pix in the first display region 11 in the same process, which is beneficial to simplify the preparation process of the second display region 12.
On the basis of the above embodiments, in another embodiment of the present application, as shown in fig. 10 and 11, fig. 10 and 11 are schematic partial enlarged views of the display panel, and the display sub-region 121 numbered j includes first-type pixels Pix2 and second-type pixels Pix3 alternately arranged along the second direction; j is more than or equal to 1 and is less than N; the second direction includes a horizontal direction or a vertical direction.
The pixel shape of the first type pixels Pix2 is the same as the pixel shape of the display pixels Pix in the first display region 11.
The pixel shape of the second type of pixels Pix3 is the same as the pixel shape of the display pixels Pix in the third display area 13.
The display pixels Pix in the display sub-region 121 with the number larger than j are all the first type pixels Pix2.
In this embodiment, the display pixels Pix in the display sub-region 121 with the number j include two pixel shapes, which are the first type pixels Pix2 and the second type pixels Pix3, respectively, the display pixels Pix in the display sub-region 121 with the number greater than j are the first type pixels Pix2, and the display pixels Pix in the display sub-region 121 with the number less than j are the second type pixels Pix3, that is, the display sub-region 121 with the number j exists as a transition region of the pixel shapes of the display pixels Pix, which is beneficial to avoiding a slight display difference possibly caused by abrupt change of the pixel shapes, and optimizing the display effect of the second display region 12. In fig. 10, the second direction is a vertical direction, and in fig. 11, the second direction is a horizontal direction.
In fig. 10 and 11, the first type pixels Pix2 have the same shape as the display pixels in the first display area 13, and in another embodiment of the present application, referring to fig. 12, fig. 12 is a partially enlarged schematic view of the display panel, and the pixel shape of the first type pixels Pix2 may also be another polygon, such as a regular pentagon, a regular hexagon, or the like, which is an excessive shape from a rectangle to the display pixels in the first display area 11.
In general, the shape of the display pixels Pix is mainly determined by the shape of the anode of the display pixels Pix, i.e. the shape of the anode of the first type of pixels Pix2 is a predetermined pattern, and the predetermined pattern comprises at least one of a circle, a triangle and a diamond. The non-rectangular shapes of the circle, the triangle and the diamond are beneficial to reducing the diffraction phenomenon of the gaps between the adjacent display pixels Pix to light, and the working performance of an optical element (such as a camera module) is beneficial to being improved.
For the display pixels Pix in the first display area 11, in order to better improve the light transmittance between the display pixels Pix, the cathode shape of the display pixels Pix in the first display area 11 is also the predetermined pattern, and the cathodes of the adjacent display pixels Pix in the first display area 11 are not in contact with each other, leaving a gap for light to pass through.
On the basis of the above embodiment, in another embodiment of the present application, as shown in fig. 13, fig. 13 is a schematic cross-sectional structure diagram of the display panel, and the display panel further includes: and the pixel circuits 20 are positioned between the substrate 10 and the display pixels Pix, and the pixel circuits 20 are used for driving the display pixels Pix to work.
The plurality of pixel circuits 20 are distributed in the second display area 12 and the third display area 13, and a part of the pixel circuits 20 distributed in the second display area 12 is used for driving the display pixels Pix located in the first display area 11 to operate.
In fig. 13, for clarity of display, only the cross-sectional schematic views of the first display region 11 and the second display region 12 are shown, and in addition, fig. 13 also shows an insulating layer 30 between the pixel circuit 20 and the display pixel Pix, and a via 31 penetrating through the insulating layer 30.
In this embodiment, the pixel circuits 20 for driving the display pixels Pix in the first display area 11 to operate are all disposed in the second display area 12, that is, the structures such as the pixel circuits 20 are not disposed in the first display area 11, so as to improve the light transmittance of the first display area 11.
On the basis of the above embodiments, in yet another embodiment of the present application, as shown in fig. 14, fig. 14 is a schematic cross-sectional structure diagram of the display panel, and the display panel further includes: and the pixel circuits 20 are positioned between the substrate 10 and the display pixels Pix, and the pixel circuits 20 are used for driving the display pixels Pix to work.
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.
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.
