Description

Technical Field

[0001] This application belongs to the field of display technology, and particularly relates to a display panel and a display device. Background Art

[0002] Full-screen has become a major trend in display devices such as mobile phones. In order to maximize the screen-to-body ratio of the display device, optical modules such as the front camera module, the front fingerprint recognition module, and the infrared sensor are all placed inside the display area as much as possible.

[0003] When the above optical modules are all arranged inside the display area, the display area corresponding to the optical module generally requires a high light transmittance so that light can enter the optical module. However, the AMOLED display screen is usually covered with opaque driving circuit metal wires, resulting in a low light transmittance of the screen body. Therefore, a new design method is needed to ensure that the optical module can function properly when it is arranged inside the display area, so as to ensure a high screen-to-body ratio and at the same time achieve a real under-screen optical sensing function. Summary of the Invention

[0004] This application provides a display panel and a display device. The display device has a sub-display area with a high light transmittance. A light-transmitting area and a light-emitting area are set in the light-emitting sub-pixels in the sub-display area, and the transmittance of the sub-display area is increased by increasing the light-transmitting area, thereby meeting the requirements of the under-screen optical module without affecting the display of the sub-display area.

[0005] To solve the above technical problems, one technical solution adopted by this application is: to provide a display panel, characterized in that it includes:

[0006] A main display area and a sub-display area, the light transmittance of the sub-display area is greater than that of the main display area;

[0007] Wherein, a plurality of first pixel units are arranged in the sub-display area, and each first pixel unit includes n first light-emitting sub-pixels of at least m colors, where m and n are natural numbers, and 1 < m < n; in the sub-display area, two adjacent first light-emitting sub-pixels of the same color have the same irregular shape and form a non-translational figure. This solution can reduce the diffraction intensity of the light transmitted to the under-screen optical module while not affecting the display of the sub-display area, meeting the requirements of the under-screen optical module. In the sub-display area, two adjacent first light-emitting sub-pixels of the same color have the same irregular shape and the same shape, but each first light-emitting sub-pixel is rotated by a preset angle relative to the other, forming a non-translational figure. A non-translational figure assumes that there are at least two identical figures. When one figure is translated onto the other, the two identical figures cannot directly overlap; when one figure is rotated by a preset angle, it can overlap with the other figure.

[0008] In the sub-display area, the first pixel units are evenly arranged, and the shapes of the first light-emitting sub-pixels of any two different colors are different.

[0009] The light-emitting layer located in the main display area is provided with a plurality of second pixel units, each second pixel unit including a plurality of second light-emitting sub-pixels of different colors; the arrangement of the second light-emitting sub-pixels in the second pixel unit is the same as that of the first light-emitting sub-pixels in the first pixel unit, and the light-emitting area of ​​the second light-emitting sub-pixels is larger than that of the first light-emitting sub-pixels of the same color.

[0010] Preferably, the second light-emitting sub-pixel in the second pixel unit and the first light-emitting sub-pixel in the first pixel unit are arranged in the same way, and the light-transmitting area of ​​the second light-emitting sub-pixel is smaller than the light-transmitting area of ​​the first light-emitting sub-pixel of the same color.

[0011] The first pixel unit includes two red luminous sub-pixels, two blue luminous sub-pixels, and two green luminous sub-pixels, forming two columns of sub-pixel groups. A virtual triangle is formed by the center positions of one red luminous sub-pixel and one green luminous sub-pixel in one column of sub-pixels and one blue luminous sub-pixel in the other column of sub-pixels. The line segment connecting the center of the red luminous sub-pixel and the center of the green luminous sub-pixel in the virtual triangle is the first line segment. The projection of the center of the blue luminous sub-pixel onto the first line segment is close to or located at the center point of the first line segment.

[0012] Wherein, the two columns of sub-pixel groups of the first pixel unit are the first sub-pixel group and the second sub-pixel group, respectively; in two adjacent first sub-pixel groups, the rotation angle of each first luminous sub-pixel in one first sub-pixel group relative to the same color first luminous sub-pixel in the other first sub-pixel group is the same, and is the first angle;

[0013] Preferably, in two adjacent second sub-pixel groups, each first luminous sub-pixel in one second sub-pixel group has the same rotation angle relative to the same color first luminous sub-pixel in the other second sub-pixel group, and the rotation angle is the second angle.

[0014] Preferably, the first angle is equal to or not equal to the second angle. The rotation angles can be the same or randomly set.

[0015] Wherein, the two columns of sub-pixel groups of the first pixel unit are the first sub-pixel group and the second sub-pixel group respectively; in the two adjacent first sub-pixel groups, the rotation angle of each first light-emitting sub-pixel in one of the first sub-pixel groups relative to the same color first light-emitting sub-pixel in the other first sub-pixel group is not equal;

[0016] In two adjacent second sub-pixel groups, the rotation angle of each first luminous sub-pixel in one of the second sub-pixel groups relative to the first luminous sub-pixel of the same color in the other second sub-pixel group is not equal.

[0017] The first pixel unit has two columns of sub-pixel groups, namely the first sub-pixel group and the second sub-pixel group; each sub-pixel group includes one red emitting sub-pixel, one green emitting sub-pixel, and one blue emitting sub-pixel; the two red emitting sub-pixels in the first sub-pixel group and the second sub-pixel group are tilted at a third angle; the two green emitting sub-pixels in the first sub-pixel group and the second sub-pixel group are tilted at a fourth angle; and the two blue emitting sub-pixels in the first sub-pixel group and the second sub-pixel group are tilted at a fifth angle.

[0018] The third angle, the fourth angle, and the fifth angle may be equal or unequal.

[0019] The sub-display area further includes an anode layer, a pixel definition layer disposed on each anode of the anode layer, an organic light-emitting material in which the first pixel unit is disposed within an opening formed by the pixel definition layer, and a cathode layer stacked on the organic light-emitting material in the opening. The opening formed by the pixel definition layer has the same shape as the first light-emitting sub-pixel projected onto the anode, and each anode of the anode layer is adapted to the shape of the first light-emitting sub-pixel projected onto the anode.

[0020] The main display area is further provided with a first pixel driving circuit that drives the first pixel unit. The first pixel driving circuit is electrically connected to each first light-emitting sub-pixel of the first pixel unit through a metal wire or a transparent wire.

[0021] Another object of the present invention is to provide a display device, characterized in that it comprises:

[0022] The display panel described above;

[0023] An optical module is located on the non-display side of the display panel and corresponds to the position of the sub-display area, and is used to receive incident light transmitted through the sub-display area.

[0024] Wherein, the pixel density of the second pixel unit in the main display area is the same as the pixel density of the first pixel unit in the sub-display area, and the size of the first pixel unit is the same as the size of the second pixel unit.

[0025] Wherein, the second light-emitting sub-pixel of the second pixel unit includes a red light-emitting sub-pixel, a green light-emitting sub-pixel, and a blue light-emitting sub-pixel; the first light-emitting sub-pixel of the first pixel unit includes a red light-emitting sub-pixel, a green light-emitting sub-pixel, and a blue light-emitting sub-pixel; wherein, the arrangement of the first light-emitting sub-pixels in the first pixel unit is the same as the arrangement of the light-emitting sub-pixels of the same color in the second pixel unit.

[0026] Unlike existing technologies, the advantages of this application are as follows: The sub-display area of ​​the display panel of this application is provided with multiple first pixel units. The first light-emitting sub-pixels of the same color within each first pixel unit have the same shape, but they form a non-translational pattern. In the sub-display area, external light can shine through the display panel from one side of the light-transmitting area of ​​the first light-emitting sub-pixels, reaching the optical module on the other side of the display panel. Furthermore, since the first light-emitting sub-pixels of the same color within each first pixel unit have the same shape but are rotated relative to each other at an angle, forming a non-translational pattern, and their arrangement is the same, this design allows for a larger and more uniform amount of external light passing through the sub-display area, resulting in more accurate optical information of the external environment collected by the optical module. In addition, because the first light-emitting sub-pixels of the same color form a non-translational pattern, the diffraction pattern formed by external light after passing through the display panel is greatly improved. The design of this invention allows the sub-display area to display images normally, resulting in a high screen-to-body ratio for the display panel. In other words, this application can achieve the function of an under-display optical module while satisfying the display requirements of the sub-display area. Attached Figure Description

[0033] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a display panel according to one embodiment of the present application. The display panel 10 includes a main display area 100, a sub-display area 102, and a non-display area S. The light transmittance of the sub-display area 102 is greater than that of the main display area 100. In this embodiment, the sub-display area 102 can be circular, elliptical, square, etc., and it can be located at the upper part, the upper middle position, the upper left corner, or other positions of the main display area 100. The present application does not limit this. The sub-display area 102 completely or partially surrounds the main display area 100.

[0035] As shown in Figure (a), it is located within the sub-display area 102 ( Figure 1 (Not shown) A plurality of first pixel units 104 are arranged in an array. Each first pixel unit 104 includes a plurality of first light-emitting sub-pixels 1040 of different colors. Each first light-emitting sub-pixel 1040 includes a light-emitting area and a light-transmitting area. For example, in this embodiment, the first light-emitting sub-pixels 1040 may include red light-emitting sub-pixels, green light-emitting sub-pixels and blue light-emitting sub-pixels of different colors.

[0036] As shown in Figure (b), multiple arrayed second pixel units 107 are arranged within the main display area 100. Each second pixel unit 107 includes multiple second light-emitting sub-pixels 1070 of different colors, and the arrangement of the light-emitting sub-pixels 1040 is the same as the arrangement of the light-emitting sub-pixels 1070 in the second pixel unit 107. The second light-emitting sub-pixels 1070 may include red, green, and blue light-emitting sub-pixels of different colors.

[0037] For example, in this embodiment, the second pixel unit 107 may include red, green, and blue light-emitting sub-pixels of different colors, and the first pixel unit 104 may include red, green, and blue light-emitting sub-pixels of different colors. Relatively speaking, the arrangement of the first light-emitting sub-pixels 1040 may be the same as the arrangement of the second light-emitting sub-pixels 1070 in the second pixel unit 107. However, for light-emitting sub-pixels of the same color, the light-emitting area of ​​the first light-emitting sub-pixel 1040 is smaller than that of the second light-emitting sub-pixel 1070.

[0038] like Figure 3 As shown, it should be noted that the arrangement here can be understood as two red luminous sub-pixels, two green luminous sub-pixels, and two blue luminous sub-pixels together forming the first pixel unit. Two red luminous sub-pixels, two green luminous sub-pixels, and two blue luminous sub-pixels together form the second pixel unit. Virtual triangles 104a and 104b are formed by the center positions of one red luminous sub-pixel and one green luminous sub-pixel in one column of sub-pixels and one blue luminous sub-pixel in another column of sub-pixels. The line segment connecting the center of the red luminous sub-pixel and the center of the green luminous sub-pixel in the virtual triangle is the first line segment 104c. The projection of the center of the blue luminous sub-pixel onto the first line segment is close to or located at the center point of the first line segment. Formally, the first pixel unit and the second pixel unit are formed by the superposition of two opposing virtual triangles.

[0039] In the above embodiment, there is a light-transmitting area between adjacent first light-emitting sub-pixels 1040 in the sub-display area 102. External light can be transmitted from the gap between the light-transmitting areas of the first light-emitting sub-pixels 1040 to the optical module on one side of the display panel 10. Since the physical size of the light-transmitting area of ​​the first light-emitting sub-pixels 1040 is relatively small, and several metal lines are arranged for electrically connecting the anode to drive the pixel to emit light, it is easy to form a diffraction spot on the optical module.

[0040] The sub-display area further includes an anode layer 101, a pixel definition layer 1042 disposed around each anode of the anode layer, an organic light-emitting material 1041 in which the first pixel unit is disposed within an opening formed by the pixel definition layer, and a cathode layer 103 stacked on the organic light-emitting material in the opening. The opening formed by the pixel definition layer has the same shape as the first light-emitting sub-pixel projected onto the anode, and each anode of the anode layer is adapted to the shape of the first light-emitting sub-pixel projected onto the anode.

[0041] The shape formed by the positive projection of each first light-emitting sub-pixel 1040 on the anode is adapted to each anode shape of the anode layer. The shapes formed by the positive projections of the red light-emitting sub-pixels, green light-emitting sub-pixels, and blue light-emitting sub-pixels on the anode are the same. For example, the shapes formed by the positive projections of the red light-emitting sub-pixels, green light-emitting sub-pixels, and blue light-emitting sub-pixels on the anode are all rectangles, ellipses, triangles, irregular polygons, etc. Preferably, the shape of the first light-emitting sub-pixel projected onto the anode is selected from irregular shapes at the edges. When an irregular shape is adopted, it is confirmed by simulation experiments that the energy of the formed diffraction spot is reduced.

[0042] In the technical solution of the present invention, a plurality of first pixel units are arranged in the sub-display area, and each of the first pixel units includes n first light-emitting sub-pixels of at least m colors, where m and n are natural numbers, and 1 < m < n; in the sub-display area, two adjacent first light-emitting sub-pixels of the same color have the same irregular shape and form a non-translational pattern. A non-translational pattern is a pattern in which it is assumed that there are at least two identical patterns, and when one pattern is translated onto the other, the two identical patterns cannot directly overlap; the two patterns can overlap only when one pattern is rotated by a preset angle. Here, m is usually 3, and n is an integer multiple of 3, that is, n = 3p, where p is a natural number greater than or equal to 1.

[0043] As Figure 4 shown, the shapes of the first light-emitting sub-pixels of the same light-emitting color within the first pixel unit are the same. The two columns of sub-pixel groups of the first pixel unit are the first sub-pixel group 104C and the second sub-pixel group 104D respectively; in two adjacent first sub-pixel groups, the rotation angle of each first light-emitting sub-pixel in one first sub-pixel group relative to the same-color first light-emitting sub-pixel in the other first sub-pixel group is the same and is the first angle A1;

[0044] In two adjacent second sub-pixel groups, the rotation angle of each first light-emitting sub-pixel in one second sub-pixel group relative to the same-color first light-emitting sub-pixel in the other second sub-pixel group is the same and is the second angle A2;

[0045] The first angle and the second angle may be equal or unequal. Since the shapes of the first light-emitting sub-pixels in the sub-display area are staggered in the layout, the regular interference formed by external light passing through the sub-display area is reduced. Therefore, the present application can weaken the diffraction problem of under-screen shooting and improve the imaging quality.

[0046] The adjustment range of the first angle can be 1° to 90°; the adjustment range of the second angle can also be 1° to 90°. The first angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°, and the second angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°. Alternatively, the first angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, and the second angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°.

[0047] In another embodiment, in two adjacent first sub-pixel groups, the rotation angle of each first luminous sub-pixel in one of the first sub-pixel groups relative to the same color first luminous sub-pixel in the other first sub-pixel group is unequal; in two adjacent second sub-pixel groups, the rotation angle of each first luminous sub-pixel in one of the second sub-pixel groups relative to the same color first luminous sub-pixel in the other second sub-pixel group is unequal. Each sub-pixel group includes one red luminous sub-pixel, one green luminous sub-pixel, and one blue luminous sub-pixel; the two red luminous sub-pixels in the first and second sub-pixel groups are tilted at a third angle (not shown in the figure); the two green luminous sub-pixels in the first and second sub-pixel groups are tilted at a fourth angle (not shown in the figure); the two blue luminous sub-pixels in the first and second sub-pixel groups are tilted at a fifth angle (not shown in the figure); the third angle, the fourth angle, and the fifth angle may be equal or unequal.

[0048] The adjustment range for the third angle is 1° to 90°; the adjustment range for the fourth angle is 1° to 90°; and the adjustment range for the fifth angle is 1° to 90°. The third angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°; the fourth angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°; and the fifth angle can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, or 80°. The third angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°. The fourth angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°. The fifth angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°.

[0049] The pixel units of the sub-display area and the main display area are arranged in the same way. Due to the rotational design of the first light-emitting sub-pixel in the sub-display area, the amount of external light passing through the sub-display area 102 is relatively large and uniform, which makes the optical information of the external environment collected by the optical module more accurate. In addition, each first pixel unit 104 is also provided with multiple light-emitting sub-pixels 1040 of different colors. The design of the light-emitting sub-pixels 1040 enables the sub-display area 102 to display images normally, and the screen ratio of the display panel 10 is relatively high. That is, this application can realize the function of an under-display optical module while satisfying the display of the sub-display area 102.

[0050] In one implementation, such as Figure 5 As shown, Figure 5 for Figure 1 A cross-sectional schematic diagram of one embodiment of a display device. The display panel 10 may include a thin-film transistor layer 106 stacked thereon and a light-emitting layer located above the thin-film transistor layer 106. Figure 4 (Not shown in the image) and an encapsulation layer 108 located above the light-emitting layer. Furthermore, an anode 101 may be disposed between the light-emitting layer and the thin-film transistor layer 106, and a cathode 103 may be disposed between the light-emitting layer and the encapsulation layer 108. Each individual first light-emitting sub-pixel 1040 within the light-emitting layer may have a separate anode 101, and multiple first light-emitting sub-pixels 1040 may share a common cathode 103.

[0051] In this embodiment, the light-emitting layer may include a patterned pixel definition layer; wherein, the light-emitting material and the pixel definition layer located outside the light-emitting material form a first light-emitting sub-pixel 1040, for example, the light-emitting material may be a red light-emitting material, a green light-emitting material, or a blue light-emitting material.

[0052] The main display area is also provided with a first pixel driving circuit that drives the first pixel unit. The first pixel driving circuit is electrically connected to each first light-emitting sub-pixel of the first pixel unit through a metal wire.

[0053] In the sub-display area, the pixel definition layer of the first light-emitting sub-pixel 1040 defined by the first pixel unit and the anode position of the first light-emitting sub-pixel can be rotated accordingly based on the rotation of the first light-emitting sub-pixel. The rotation angle of the orthographic projection shape of each first light-emitting sub-pixel in the same first pixel unit on the thin-film transistor layer 106 is the same, that is, the rotation angle of each first light-emitting sub-pixel in the first sub-pixel group relative to each first light-emitting sub-pixel in the second sub-pixel group is the same. On the one hand, the regular arrangement of the opaque area in the sub-display area can be disrupted, reducing the diffraction spot energy of the sub-display area 102, especially the first-order energy and the zero-order energy; on the other hand, since it is a rotation of the entire sub-pixel group, the process complexity can be reduced.

[0054] Correspondingly, when the first light-emitting sub-pixel rotates, the driving circuit electrically connected to it, which drives the first light-emitting sub-pixel to emit light, adjusts its position to achieve transparent display. Using RSoft ComponentSuite software, simulations were performed with the change in level 1 energy / level 0 energy as the result and the rotation angle of the first light-emitting sub-pixel as the variable. It was determined that when the first light-emitting sub-pixel rotates by a preset angle, the level 1 energy / level 0 energy decreases.

[0055] In an application scenario, such as Figure 1As shown, the sub-display area 102 includes multiple first pixel units 104. This design allows ambient light to be incident more uniformly from the sub-display area 102 onto the optical module. For example, in this embodiment, the red and green light-emitting sub-pixels within each first pixel unit 104 can be located in the same column, while the blue light-emitting sub-pixels are located in another column. A virtual triangle is formed by the center positions of one red and one green light-emitting sub-pixel in one column and one blue light-emitting sub-pixel in the other column. The line segment connecting the center of the red and green light-emitting sub-pixels in this virtual triangle is the first line segment, and the projection of the center of the blue light-emitting sub-pixel onto this first line segment is close to or located at the center point of the first line segment. The first pixel units are arranged in a way that creates two diagonally stacked virtual triangles, resulting in a uniform distribution of light-emitting sub-pixels. This design can reduce color shift when the repeating unit 105 emits light.

[0056] For the main display area 100, please refer to the following again. Figure 1 The pixel density of the second pixel unit 107 in the main display area 100 is the same as the pixel density of the first pixel unit 104 in the sub-display area 102, and the size of the first pixel unit 104 can be different from the size of the second pixel unit 107. Here, the pixel density of the second pixel unit 107 refers to the number of second pixel units 107 per inch of the main display area 100, and the pixel density of the first pixel unit 104 refers to the number of first pixel units 104 per inch of the sub-display area 102. This design can minimize the difference in display effect between the main display area 100 and the sub-display area 102, thereby improving the full-screen display effect.

[0057] In an application scenario, such as Figure 1 As shown, the second pixel unit 107 includes red, green, and blue luminous sub-pixels of different colors, which together participate in image display. The layout of the first and second pixel units is roughly the same, and the luminous color of the first luminous sub-pixel in the second pixel unit 107 is the same as the luminous color of the first luminous sub-pixel at the corresponding position in the first pixel unit 104. In this embodiment, the second pixel unit 107 adopts a pixel structure with two diagonally stacked virtual triangles, which provides good saturation and uniformity.

[0058] Furthermore, the arrangement of the light-emitting sub-pixels 1040 in the first pixel unit 104 is the same as the arrangement of the light-emitting sub-pixels 1070 of the same color in the second pixel unit 107. This design can reduce the complexity of the manufacturing process of the first pixel unit 104 and the second pixel unit 107; and when the first light-emitting sub-pixels 1040 in the first pixel unit 104 are red, green and blue light-emitting sub-pixels respectively, the first pixel unit 104 can still synthesize light of various colors to ensure the display effect.

[0059] In addition, the size of the first light-emitting sub-pixel 1040 in the first pixel unit 104 is different from the size of the second light-emitting sub-pixel 1070 with the same color in the second pixel unit 107. This can be adjusted according to the requirements of light emission and light transmittance. This layout design can also reduce the complexity of the manufacturing process of the first pixel unit 104 and the second pixel unit 107.

[0060] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of one embodiment of the display device of this application. The display device 20 includes a display panel and an optical module 202 as described in any of the above embodiments. The optical module 202 is located on the non-display surface 2000 side of the display panel and corresponds to the position of the sub-display area (not shown). The non-display surface 2000 can be the side of the thin-film transistor layer away from the light-emitting layer, and the optical module 202 can be a front-facing camera module, a front-facing fingerprint recognition module, etc.

[0061] In one embodiment, when the optical module 202 is a camera module, the operation of the display device 20 can be as follows: when the camera function is turned on, ambient light enters the camera through the transparent area gap of the first light-emitting sub-pixel in the sub-display area, and the camera collects the incident ambient light to obtain an external image; the camera sends the collected image to the control chip, and the control chip drives the light-emitting sub-pixels in the main display area and the sub-display area to emit light so as to display the external image on the display panel.

[0062] According to an embodiment of the present invention, the light transmittance of the sub-display area 102 is greater than that of the main display area 100, allowing a photosensitive component to be integrated on the back of the sub-display area 102. The photosensitive component can be an image acquisition device used to acquire external image information.
