Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device having the display panel. Background Art

[0002] With the continuous advancement of science and technology, visual information plays an increasingly important role in people's lives. Therefore, display devices that carry visual information, such as televisions, computers, mobile phones, wearable devices, etc., also play an increasingly important role in people's lives. With the continuous development of display technology, people have also put forward higher quality requirements for display devices, such as display devices with higher screen-to-body ratios. In order to increase the screen-to-body ratio of display devices, high screen-to-body ratio display screens such as bangs screens, water drop screens, and punch-hole screens have emerged. Among them, the hollow screen has the best screen-to-body ratio and screen display effect.

[0003] At present, the methods used for hole-punch screens include "blind holes" and "through holes", and the cameras are set at the bottom of the screen corresponding to the "blind holes" and "through holes". Among them, the "through hole" is relatively simple from a technical perspective, but the visual integrity of the "through hole" is much worse. Because there is no need to consider the impact of the screen on the camera, the hole made by the "through hole" on the screen will be larger than the camera itself, and larger than the aperture of the "blind hole". Therefore, compared with the "through hole", the "blind hole" has a higher visual integrity.

[0004] However, the blind hole is more difficult to make because the camera is set under the screen, and in the LCD panel, the blind hole is usually covered with an alignment layer, and the material of the alignment layer is polyimide, which makes the overall color of the alignment layer yellowish and the light transmittance is not high, which in turn affects the imaging quality of the camera. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0040] The embodiment of the present invention provides a display panel. Figure 1 The display panel includes a first substrate 11 , a first display function layer 12 , a first boss structure 131 and a first alignment layer 15 .

[0041] Among them, the first display function layer 12 is arranged on the first substrate 11 and includes a first light-transmitting opening 101; the first boss structure 131 is arranged in the first light-transmitting opening 101; the first alignment layer 15 is arranged on the side of the first display function layer 12 away from the first substrate 11, and the orthographic projection of the first alignment layer 15 on the first substrate 11 does not overlap with the orthographic projection of the first boss structure 131 on the first substrate 11.

[0042] Furthermore, the first boss structure 131 protrudes from the surface of the first alignment layer 15 away from the first substrate 11 , and the light transmittance of the first boss structure 131 is greater than the light transmittance of the first alignment layer 15 .

[0043] When implementing your application, please refer to Figure 2 In the under-screen camera display panel of the related art, the display panel includes an array substrate 1 and a color film substrate 5 arranged relatively to each other, a thin film transistor array layer 2, an insulating layer 3 and a first alignment film 4 arranged on the array substrate 1, a color film layer 6, a flat protective layer 7 and a second alignment film 8 arranged on the color film substrate 5, and a liquid crystal layer 9 arranged between the array substrate 1 and the color film substrate 5; in order to improve the imaging effect of the under-screen camera, blind holes A and blind holes B are often opened in the display panel, but since the first alignment film 4 and the second alignment film 8 cover the blind holes A and the blind holes B, and the materials of the first alignment film 4 and the second alignment film 8 are both polyimide materials, their transmittance to light with a wavelength of 380nm to 450nm is low, and the material as a whole is yellowish, which will affect the imaging effect of the under-screen camera. In the embodiment of the present invention, by setting the first boss structure 131 in the first light-transmitting opening 101 of the first substrate 11, the material of the first alignment layer 15 can be prevented from forming a film at the first boss structure 131 during the coating process of the first alignment layer 15, and the light transmittance of the first boss structure 131 is greater than the light transmittance of the first alignment layer 15, thereby improving the light transmittance of the first light-transmitting opening 101. When the camera assembly is arranged under the display panel corresponding to the first light-transmitting opening 101, the imaging effect of the camera assembly can be improved.

[0044] Specifically, the structure of the display panel provided by the embodiment of the present invention is described in detail below in conjunction with the embodiment.

[0045] Please combine Figure 1 as well as Figure 3In one embodiment of the present invention, the display panel includes a first substrate 11 and a second substrate 21 arranged opposite to each other; and the display panel also includes a first display function layer 12 arranged on a side of the first substrate 11 close to the second substrate 21, an organic insulating layer 13 arranged on a side of the first display function layer 12 close to the second substrate 21, an inorganic insulating layer 14 arranged on a side of the organic insulating layer 13 close to the second substrate 21, and a first alignment layer 15 arranged on a side of the inorganic insulating layer 14 close to the second substrate 21; the display panel also includes a second display function layer 22 arranged on a side of the second substrate 21 close to the first substrate 11, a flat layer 23 arranged on a side of the second display function layer 22 close to the first substrate 11, and a second alignment layer 24 arranged on a side of the flat layer 23 close to the first substrate 11; the display panel also includes a liquid crystal layer 18 arranged between the first alignment layer 15 and the second alignment layer 24.

[0046] It should be noted that, in the embodiment of the present invention, the first display function layer 12 includes a thin film transistor layer, and the organic insulating layer 13 covers the thin film transistor layer, wherein the display panel further includes an electrode layer disposed on the side of the organic insulating layer 13 close to the second substrate 21, and the inorganic insulating layer covers the electrode layer. Specifically, the electrode layer includes a common electrode disposed on the side of the organic insulating layer 13 close to the second substrate 21, and the inorganic insulating layer 14 includes a first inorganic layer covering the common electrode, the electrode layer further includes a pixel electrode disposed on the side of the first inorganic layer close to the second substrate 21, and the inorganic insulating layer 14 further includes a second inorganic layer covering the pixel electrode, and the first alignment layer 15 can be disposed on the side of the second inorganic layer close to the second substrate 21.

[0047] In the embodiment of the present invention, the first display function layer 12 includes a first light-transmitting opening 101, wherein the first light-transmitting opening 101 at least passes through a portion of the first display function layer 12, that is, passes through at least a portion of the thin film transistor layer. In the embodiment of the present invention, the first light-transmitting opening 101 is formed by removing the entire thickness of the first display function layer 12, and the common electrode and the pixel electrode are both arranged away from the first light-transmitting opening 101. The organic insulating layer 13 covers the first display function layer 12 and extends into the first light-transmitting opening 101 to form a first boss structure 131 arranged in the first light-transmitting opening 101, and the first boss structure 131 at least protrudes from the surface of the first display function layer 12 away from the first substrate 11.

[0048] The orthographic projection of the inorganic insulating layer 14 on the first substrate 11 and the orthographic projection of the first boss structure 131 on the first substrate 11 are arranged not to overlap, which can be specifically prepared by controlling the mask pattern during the manufacturing process.

[0049] The orthographic projection of the first alignment layer 15 on the first substrate 11 and the orthographic projection of the first boss structure 131 on the first substrate 11 are not overlapped.

When the alignment plate 17 is in contact with the side of the first substrate 11 provided with the first boss structure 131, the transfer wheel 16 drives the alignment plate 17 to rotate and squeezes the alignment plate 17 to squeeze the alignment liquid in each concave point onto the inorganic insulating layer 14 for film formation. However, when the alignment plate 17 moves to the first boss structure, the first boss structure 131 and the transfer wheel 16 squeeze both sides of the alignment plate 17 at the same time, so that the alignment liquid overflowing from the concave point is squeezed to a position outside the first boss structure 131, and the first alignment layer 15 finally formed is staggered with the first boss structure 131, and the first boss structure 131 protrudes from the surface of the first alignment layer 15 away from the first substrate 11.

[0051] Optionally, a distance from a surface of the first boss structure 131 on a side away from the first substrate 11 to the first substrate 11 is less than or equal to a distance between the first substrate 11 and the second substrate 21 .

[0053] The second display function layer 22 includes a second light-transmitting opening 201, which can pass through at least a portion of the second display function layer 22. In the embodiment of the present invention, the second light-transmitting opening 201 passes through the entire second display function layer 22. The first light-transmitting opening 101 and the second light-transmitting opening 201 are arranged in alignment, and the flat layer 23 and the second alignment layer 24 both cover the second display function layer 22 and the inner wall of the second light-transmitting opening 201.

[0054] As mentioned above, in the embodiment of the present invention, an organic insulating layer 13 is used to set a first boss structure 131 in the first light-transmitting opening 101 passing through the thin-film transistor layer, thereby avoiding the first alignment layer 15 from covering the first light-transmitting opening 101, and the light transmittance of the first boss structure 131 is greater than the light transmittance of the first alignment layer 15, so as to improve the light transmittance of the first light-transmitting opening 101, thereby improving the imaging quality of the camera assembly corresponding to the first light-transmitting opening 101.

[0057] The orthographic projection of the first alignment layer 34 on the first substrate 11 does not overlap with the orthographic projection of the first boss structure 331 on the first substrate 11 , and the first boss structure 331 protrudes from the surface of the first alignment layer 34 away from the first substrate 11 .

Specifically, the transmittance of the flat layer 33 for light with a wavelength of 380nm to 780nm is greater than 99%, and thus the embodiment of the present invention can effectively improve the light transmittance of the first light-transmitting opening 301.

[0059] Optionally, a distance from a surface of the first boss structure 331 away from the first substrate 31 to the first substrate 31 is less than or equal to a distance between the first substrate 31 and the second substrate 41 .

[0060] The second display function layer 42 may be a thin film transistor layer, and the second display function layer 42 includes a second light-transmitting opening 401 that passes through the entire second display function layer 42, and the organic insulating layer 43 covers the second display function layer 42 and extends into the second light-transmitting opening 401 to cover the inner wall of the second light-transmitting opening 401; further, the inorganic insulating layer 44 covers the organic insulating layer 43 and the second light-transmitting opening 401, and the second alignment layer 45 covers the inorganic insulating layer 44 and the second light-transmitting opening 401.

[0061] As mentioned above, in the embodiment of the present invention, a flat layer 33 is used to form a first boss structure 331 in the first light-transmitting opening 301 passing through the color filter layer, thereby avoiding the first alignment layer 34 from covering the first light-transmitting opening 301, and the light transmittance of the first boss structure 331 is greater than the light transmittance of the first alignment layer 34, so as to improve the light transmittance of the first light-transmitting opening 301, thereby improving the imaging quality of the camera assembly corresponding to the first light-transmitting opening 301.

[0062] In another embodiment of the present invention, please combine Figure 6 as well as Figure 7 In this embodiment, the display panel includes a first substrate 51 and a second substrate 61 which are arranged opposite to each other, and the display panel also includes a first display function layer 52 arranged on a side of the first substrate 51 close to the second substrate 61, a flat layer 53 arranged on a side of the first display function layer 52 close to the second substrate 61, a spacer layer arranged on a side of the flat layer 53 close to the second substrate 61, and a first alignment layer 55 arranged on a side of the spacer layer close to the second substrate 61.

[0065] It should be noted that, in the present embodiment, the distance from the surface of the first boss structure 541 away from the first substrate 51 to the first substrate 51 is greater than the distance from the surface of the spacer column 542 away from the first substrate 51 to the first substrate 51. Therefore, during the formation of the first alignment layer 55, the first boss structure 541 and the transfer wheel exert a greater squeezing force on the alignment plate, which can squeeze out the alignment liquid.
