Detailed Implementation

[0031] 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 them. 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. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or working state, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0032] This application provides a display panel, such as Figures 1 to 6 As shown, the display panel includes a first substrate 10, a second substrate 20, a color filter layer 30, a plurality of first light-shielding portions 40, and a plurality of second light-shielding portions 50; the first substrate 10 and the second substrate 20 are opposite to each other and spaced apart; the color filter layer 30 is disposed on the side of the first substrate 10 near the second substrate 20, or on the side of the second substrate 20 near the first substrate 10; the color filter layer 30 includes a plurality of color resists 31; the plurality of first light-shielding portions 40 extend along a first direction D1, and the first light-shielding portions 40 are disposed on the side of the first substrate 10 near the second substrate 20 or / and the second substrate 20 near the first substrate. On one side of the first substrate 10; a plurality of second light-shielding portions 50 extend along the second direction D2, the first direction D1 and the second direction D2 are arranged at an angle, the second light-shielding portions 50 are disposed on the side of the first substrate 10 near the second substrate 20 or / and the side of the second substrate 20 near the first substrate 10; wherein, the orthographic projection pattern of the first light-shielding portion 40 and the second light-shielding portion 50 on the color filter layer 30 covers the boundary line of each color filter 31, and neither the first light-shielding portion 40 nor the second light-shielding portion 50 are all located on the side of the first substrate 10 near the second substrate 20 or the side of the second substrate 20 near the first substrate 10.

[0033] It should be noted that, Figure 2 , Figure 4 and Figure 5 Only a portion of the film layers are shown, not all the film layers of the display panel. Those skilled in the art will know that an insulating layer can be provided between two adjacent metal layers to prevent short circuits between them. Figure 6 It shows Figure 1 A specific cross-sectional structure of a display panel.

[0034] In this embodiment, the display panel is a liquid crystal display panel. The liquid crystal display panel can be any one of the following types: vertical alignment (VA), twisted nematic (TN), super twisted nematic (STN), in-plane switching (IPS), and fringe field switching (FFS).

[0035] In this embodiment, the materials of the first substrate 10 and the second substrate 20 can be glass, etc., but are not limited thereto. A liquid crystal layer (not shown in the figure) can be disposed between the first substrate 10 and the second substrate 20. It should be understood that the liquid crystal layer is deflected under the action of an electric field, thereby achieving control over the transmittance of light. A first electrode layer 61 can be disposed on one side of the first substrate 10, and a second electrode layer 62 can be disposed on one side of the second substrate 20. The liquid crystal layer is deflected under the action of the electric field formed by the first electrode layer 61 and the second electrode layer 62.

[0036] Optionally, in some embodiments, the first electrode layer 61 and the second electrode layer 62 may both be disposed on the first substrate 10, or the first electrode layer 61 and the second electrode layer 62 may both be disposed on the second substrate 20. This application does not limit this.

[0037] In this embodiment, the color filter layer 30 can be disposed on the first substrate 10 and located inside the first substrate 10, or on the second substrate 20 and located inside the second substrate 20. Here, the inside of the first substrate 10 refers to the side of the first substrate 10 close to the second substrate 20, and the inside of the second substrate 20 refers to the side of the second substrate 20 close to the first substrate 10.

[0038] It should be understood that each film layer in this application is disposed on the inner side of the first substrate 10 and / or the second substrate 20, so that the first substrate 10 and the second substrate 20 can protect each film layer.

[0039] The color filter layer 30 includes multiple color resists 31, each of which can be configured to correspond to a sub-pixel of the display panel. The color resists 31 can include red, green, and blue color resists. Each color resist 31 allows light of a color corresponding to its own color to pass through, thus filtering the color of the light. For example, a red color resist allows red light to pass through, a green color resist allows green light to pass through, and a blue color resist allows blue light to pass through. The color resists 31 can be used to convert white light into colored light, thereby achieving color display.

[0040] In this embodiment, a plurality of first light-shielding portions 40 extend along a first direction D1. The first light-shielding portions 40 can be made of a material with light-shielding function. For example, the material of the first light-shielding portions 40 can be an organic material or a metal. The first light-shielding portions 40 can be doped with materials such as carbon black or black ink to achieve a light-shielding effect.

[0041] The first light-blocking part 40 can be elongated. The first light-blocking part 40 is disposed between two adjacent color resists 31, thereby avoiding color crosstalk at the boundary of the two adjacent color resists 31 in the first direction D1 and improving color deviation.

[0042] In this embodiment, a plurality of second light-shielding portions 50 extend along the second direction D2. The second light-shielding portions 50 can be made of a material with light-shielding function. For example, the material of the second light-shielding portions 50 can be an organic material or a metal. The second light-shielding portions 50 can be doped with materials such as carbon black or black ink to achieve a light-shielding effect. The material of the first light-shielding portion 40 can be the same as or different from the material of the second light-shielding portions 50; this application does not impose any limitations on this.

[0043] The second light-blocking part 50 can be elongated. The second light-blocking part 50 is disposed between two adjacent color resists 31, thereby avoiding color crosstalk at the boundary of the two adjacent color resists 31 in the second direction D2 and improving color deviation.

[0044] The second direction D2 is set at an acute angle or a right angle to the first direction D1. Multiple first light-blocking portions 40 and multiple second light-blocking portions 50 define the light-transmitting area of ​​the sub-pixel. It should be understood that the first light-blocking portions 40 and the second light-blocking portions 50 may overlap or not overlap in their intersection area.

[0045] Optionally, in some embodiments, the display panel includes data lines 81 and scan lines (not shown in the figure), which intersect to define the light-transmitting area of ​​a sub-pixel. The data lines 81 and scan lines may extend along one of a first direction D1 and a second direction D2, respectively.

[0046] It should be understood that the orthographic projection of the first light-shielding part 40 and the second light-shielding part 50 on the display surface covers the data line 81 and the scan line, thereby shielding the data line 81 and the scan line.

[0047] In this embodiment, the orthographic projection patterns of the first light-blocking portion 40 and the second light-blocking portion 50 on the color filter layer 30 cover the boundary line of each color resist 31. That is to say, the orthographic projection patterns of the first light-blocking portion 40 and the second light-blocking portion 50 form a grid-like light-blocking pattern, which is disposed between two adjacent sub-pixels and covers the boundary line of each color resist 31, thereby avoiding color crosstalk at the boundary of two adjacent color resists 31 in any direction and improving color shift.

[0048] In this embodiment, neither the first light-shielding portion 40 nor the second light-shielding portion 50 is entirely located on the side of the first substrate 10 near the second substrate 20 or on the side of the second substrate 20 near the first substrate 10. That is to say, both the first substrate 10 and the second substrate 20 are provided with at least a portion of the first light-shielding portion 40 and the second light-shielding portion 50, and neither of the first light-shielding portion 40 nor the second light-shielding portion 50 can be omitted.

[0049] For example, all of the first light-shielding portions 40 can be provided on the first substrate 10, and all of the second light-shielding portions 50 can be provided on the second substrate 20. Alternatively, some of the first light-shielding portions 40 can be provided on the first substrate 10, and some of the first light-shielding portions 40 and all of the second light-shielding portions 50 can be provided on the second substrate 20. The first substrate 10 and the second substrate 20 can be interchanged.

[0050] This application disperses the first light-shielding part 40 and the second light-shielding part 50 on the first substrate 10 and the second substrate 20, thereby increasing the distance between two adjacent light-shielding parts on any one substrate. This is equivalent to increasing the size of the opening through which light can pass, thereby reducing the diffraction effect between light passing through multiple openings and improving the diffraction stripe problem of high-resolution display panels.

[0051] In the display panel of this application, as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the surface of the first substrate 10 facing away from the second substrate 20 is the light-emitting surface 10a of the display panel. The size of the color resist 31 in the first direction D1 is smaller than the size in the second direction D2. The first light-shielding part 40 is disposed on the side of the first substrate 10 close to the second substrate 20.

[0052] In this embodiment, the surface of the first substrate 10 facing away from the second substrate 20 is the light-emitting surface 10a of the display panel. This means that the surface of the second substrate 20 facing away from the first substrate 10 can be the light-incident surface. The light-incident surface can be positioned close to the backlight module, which can be used to provide a backlight for the display panel. Light emitted from the backlight module enters the display panel from the light-incident surface, is adjusted by the liquid crystal layer, and then exits from the light-emitting surface 10a, which is used to display the image.

[0053] In this embodiment, a first electrode layer 61 is disposed on a first substrate 10, and the first electrode layer 61 can be a common electrode layer. A second electrode layer 62 is disposed on a second substrate 20, and the second electrode layer 62 can be a pixel electrode layer, which includes multiple pixel electrodes, with one pixel electrode corresponding to one sub-pixel.

[0054] like Figure 6 As shown, an array layer may be disposed on the second substrate 20, and a driving circuit is disposed on the array layer. The driving circuit includes a plurality of thin film transistors 70, which are used to connect to the pixel electrode of each sub-pixel, thereby providing a corresponding driving voltage for each sub-pixel.

[0055] In this embodiment, the size of the color resist 31 in the first direction D1 is smaller than its size in the second direction D2, and all the first light-shielding portions 40 are disposed on the inner side of the first substrate 10. This means that no first light-shielding portions 40 are disposed on the inner side of the second substrate 20. Alternatively, all of the second light-shielding portions 50 may be disposed on the inner side of the second substrate 20, or a portion of the second light-shielding portions 50 may be disposed on the inner side of the first substrate 10, and another portion may be disposed on the inner side of the second substrate 20.

[0056] Optionally, such as Figure 2 As shown, Figure 2 This is a cross-sectional structural diagram of the first type of display panel of this application. In the first type of display panel of this application, the color filter layer 30 is disposed on the side of the first substrate 10 near the second substrate 20, and the second light-shielding portion 50 includes a first sub-portion 51 and a second sub-portion 52. The first sub-portion 51 is disposed on the side of the color filter layer 30 away from the first substrate 10, and the second sub-portion 52 is disposed on the side of the second substrate 20 near the first substrate 10.

[0057] In this embodiment, the second light-shielding portion 50 includes a first sub-portion 51 and a second sub-portion 52. The first sub-portion 51 and the second sub-portion 52 can be disposed in different layers. For example, the first sub-portion 51 can be disposed on the inner side of the first substrate 10, and the second sub-portion 52 can be disposed on the inner side of the second substrate 20.

[0058] Furthermore, in all embodiments of this application, the first sub-part 51 and the first light-shielding part 40 can be arranged on the same layer, thereby allowing the first light-shielding part 40 and the first sub-part 51 to be manufactured using the same process, simplifying the manufacturing process of the display panel. The first sub-part 51 and the first light-shielding part 40 can be a black matrix.

[0059] Optionally, in some embodiments, the thickness of the second sub-part 52 is greater than the thickness of the first sub-part 51, and the second sub-part 52 can be a support wall. The support wall can be made of resin material. Besides providing light-shielding, the support wall also serves a supporting function to maintain the distance between the first substrate 10 and the second substrate 20. This means that by providing a support wall, the conventional support pillar can be eliminated. Compared to a support pillar, the support wall has a larger contact area with the first substrate 10, providing more stable support.

[0060] The following is combined with Figure 3 The diffraction effect is explained to illustrate the improvement principle of this application. For ease of description, the opening in the light-transmitting area between the two first light-shielding portions 40 and / or the first sub-portion 51 of the first substrate 10 is referred to as the first opening 11, and the opening in the light-transmitting area between the two second light-shielding portions 50 of the second substrate 20 is referred to as the second opening 22. Light rays S enter from the light-incident surface of the second substrate 20, pass through the second opening 22, and then exit through the first opening 11. The interference of light rays S exiting from different openings causes a diffraction effect, forming diffraction fringes. It should be understood that the strength of the diffraction effect is affected not only by the opening sizes of the first opening 11 and the second opening 22, but also by the distance between the first opening 11 and the second opening 22 in the thickness direction of the display panel. Specifically, the smaller the size of the first opening 11 in any direction, the stronger the diffraction effect in that direction. Within a certain range, the larger the distance between the first opening 11 and the second opening 22, the stronger the diffraction effect. Through practice, the inventors discovered that when the distance between the first opening 11 and the second opening 22 is less than 3.5 micrometers, the visual diffraction stripes of the display panel are significantly improved.

[0061] However, since a liquid crystal layer and a first electrode layer 61 and a second electrode layer 62 are required between the first opening 11 and the second opening 22, the distance between the first opening 11 and the second opening 22 cannot be reduced indefinitely.

[0062] In this embodiment, the color filter layer 30 is disposed on the side of the first substrate 10 near the second substrate 20, and the first sub-part 51 is disposed on the side of the color filter layer 30 away from the first substrate 10. Since the first sub-part 51 is disposed on the side of the color filter layer 30 near the second substrate 20, the gap between the first opening 11 and the second opening 22 can be reduced, and the reduced thickness is the thickness of the color filter layer 30, thereby weakening the diffraction effect.

[0063] Optionally, such as Figure 4 As shown, Figure 4 This is a cross-sectional structural diagram of the second type of display panel of this application. The difference between the second type of display panel and the first type of display panel lies in the position of the color filter layer 30. In the second type of display panel, the color filter layer 30 is disposed on the side of the second substrate 20 near the first substrate 10, and the second light-shielding portion 50 includes a first sub-portion 51 and a second sub-portion 52. The first sub-portion 51 is disposed on the side of the first substrate 10 near the second substrate 20, and the second sub-portion 52 is disposed on the side of the color filter layer 30 away from the second substrate 20.

[0064] In this embodiment, the color filter layer 30 can be disposed on the inner side of the second substrate 20, that is, the display panel can be a COA (Color Filter On Array) architecture, which means that the color filter layer 30 is disposed on the array substrate. The second sub-part 52 is disposed on the side of the color filter layer 30 away from the second substrate 20.

[0065] like Figure 6 As shown, Figure 6 A cross-sectional structure of a display panel with a COA architecture is shown. An array layer is disposed on a second substrate 20, and a color filter layer 30 is disposed on the side of the array layer opposite to the second substrate 20. The array layer includes thin-film transistors 70. The source 71 of the thin-film transistors 70 can be electrically connected to a data line 81, and the drain 72 of the thin-film transistors 70 is electrically connected to a pixel electrode to provide a driving voltage for the sub-pixels. The first electrode layer 61 and the second electrode layer 62 can both be disposed on the second substrate 20. The first electrode layer 61 can be a common electrode layer, and the second electrode layer 62 can be a pixel electrode layer, but is not limited thereto.

[0066] In this embodiment, the materials of the first sub-part 51 and the second sub-part 52 can be the same as those of the first type of display panel, which will not be repeated here.

[0067] Optionally, in some embodiments, at least one second sub-part 52 is disposed between two adjacent first sub-parts 51. That is, the first sub-parts 51 and the second sub-parts 52 can be disposed alternately, and at least one second sub-part 52 can be disposed between two adjacent first sub-parts 51. Since the smallest first opening 11 is defined by the adjacent first light-shielding part 40 and the first sub-part 51, when at least one second sub-part 52 is disposed between two adjacent first sub-parts 51, the two adjacent first sub-parts 51 in the first direction D1 are at least separated by two color filters 31, thereby increasing the spacing between the two adjacent first sub-parts 51 in the first direction D1, that is, increasing the size of the smallest first opening 11, thereby reducing the diffraction effect and improving the diffraction fringe problem.

[0068] It should be understood that in the above embodiments, the first electrode layer 61 can be disposed on the inner surface of the first substrate 10, and the second electrode layer 62 can be disposed on the inner surface of the second substrate 20, so that when the thickness of the liquid crystal layer is constant, the distance between the first electrode layer 61 and the second electrode layer 62 is smaller, thereby enhancing the strength of the electric field formed by the first electrode layer 61 and the second electrode layer 62.

[0069] Optionally, such as Figure 5 As shown, Figure 5 This is a cross-sectional structural diagram of the third type of display panel of this application. The difference between the third type of display panel and the second type of display panel lies in the second light-shielding portion 50. In the third type of display panel, the color filter layer 30 is disposed on the side of the second substrate 20 close to the first substrate 10, and the second light-shielding portions 50 are all disposed on the side of the color filter layer 30 away from the second substrate 20. The second light-shielding portion 50 includes alternately disposed second sub-parts 52 and third sub-parts 53, and the thickness of the second sub-part 52 is greater than the thickness of the third sub-part 53.

[0070] In this embodiment, the configuration of the second sub-section 52 of the third display panel can be the same as that of the second sub-section 52 of the second display panel.

[0071] In this embodiment, the third sub-part 53 can be disposed on the second substrate 20, and the third sub-part 53 is disposed on the side of the color filter layer 30 facing away from the second substrate 20. With the above arrangement, the distance between the first opening 11 and the second opening 22 in the thickness direction of the display panel can be reduced, thereby weakening the diffraction effect and improving the problem of diffraction stripes appearing on the display panel under visual observation.

[0072] In this embodiment, the third sub-part 53 can be made of a metal light-shielding layer, which can be fabricated using a sputtering process. Compared to a light-shielding layer made of resin, the metal light-shielding layer has a smaller thickness, thereby reducing the thickness of the third sub-part 53. Simultaneously, the metal light-shielding layer is conductive, thus not affecting the electric field at the edge of the metal light-shielding layer, preventing the placement of the third sub-part 53 from affecting the deflection of the liquid crystal.

[0073] In some embodiments, the third sub-part 53 may also be disposed on the side of the second electrode layer 62 facing away from the second substrate 20, or the third sub-part 53 may be disposed between the second electrode layer 62 and the color filter layer 30. When the third sub-part 53 is closer to the first substrate 10, it helps to reduce the distance between the first opening 11 and the second opening 22 in the thickness direction of the display panel, thereby reducing the diffraction effect and improving the problem of diffraction stripes appearing on the display panel under visual observation.

[0074] In the display panel of this application, as Figures 2 to 5As shown, a boss 21 is provided on the side of the second substrate 20 near the first substrate 10. The boss 21 is aligned with the second sub-part 52, and at least part of the second sub-part 52 is provided on the side of the boss 21 away from the second substrate 20.

[0075] In this embodiment, the boss 21 can raise part of the second sub-part 52, thereby creating a step difference in the thickness direction of the display panel, which disrupts the periodicity of light emission from the second opening 22 and weakens the diffraction effect.

[0076] Furthermore, one or more second sub-parts 52 can be provided between two adjacent protrusions 21, and the setting period of the protrusions 21 can be set as needed. It should be noted that when the protrusions 21 are set with multiple repetition periods, the effect of reducing diffraction effect is better.

[0077] In this embodiment, the alignment of the boss 21 and the second sub-part 52 means that the orthographic projection of the boss 21 on the second substrate 20 overlaps with the orthographic projection of the second sub-part 52 on the second substrate 20. The width of the boss 21 in the first direction D1 can be slightly larger than the width of the second sub-part 52 in the first direction D1, thereby avoiding the boss 21 occupying too much of the area of ​​the light-transmitting region of the display panel and reducing the aperture ratio of the display panel.

[0078] In the display panel of this application, the end of the second sub-part 52 corresponding to the boss 21 that is away from the boss 21 abuts against the first substrate 10.

[0079] In this embodiment, the second sub-part 52 corresponding to the boss 21 can be the main support wall, playing a primary support role, while the second sub-part 52 not corresponding to the boss 21 can be the secondary support wall, playing a secondary support role.

[0080] The second sub-section 52 has a certain elastic deformation capability. When the display panel is not under pressure, the main support wall provides support; when the display panel is under pressure, the gap between the first substrate 10 and the second substrate 20 decreases, and the secondary support wall can provide support. By setting two support walls of different heights, the pressure resistance of the display panel can be improved, while increasing the margin of the liquid crystal layer (LC Margin).

[0081] In the display panel of this application, the first light-shielding part 40 is disposed on the side of the first substrate 10 near the second substrate 20, and the width of the second light-shielding part 50 is less than or equal to the width of the first light-shielding part 40.

[0082] The width of the first light-shielding part 40 refers to its dimension in the direction perpendicular to the first direction D1, and the width of the second light-shielding part 50 refers to its dimension in the direction perpendicular to the second direction D2. By setting the width of the second light-shielding part 50 to be less than or equal to the width of the first light-shielding part 40, excessive light can be prevented from being blocked by the second light-shielding part 50.

[0083] This application provides a display terminal, which includes the display panel described above.

[0084] In this embodiment, the display terminal can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0085] It should be noted that the display panel in this application can be a high-resolution display panel, such as a product with a resolution of 1500 PPI (Pixels Per Inch) or higher, which is particularly suitable for VR (Virtual Reality) products.
