Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few 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.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic plan view of a special-shaped liquid crystal display panel according to an embodiment of the present disclosure, and fig. 2 is a schematic partial enlarged view of a light shielding layer disposed at a position a of the special-shaped liquid crystal display panel shown in fig. 1. The special-shaped LCD panel 100 can be a vertical alignment type LCD panel, a planar switching type LCD panel, or a fringe field switching type LCD panel. One end of the special-shaped liquid crystal display panel 100 has a notch 100a, and the notch 100a is located in the middle of one end of the special-shaped liquid crystal display panel 100, so as to divide one end of the special-shaped liquid crystal display panel 100 into two special-shaped areas.
The special-shaped display LCD panel 100 has a display area including a non-special-shaped display area 100b and at least one special-shaped display area 100c adjacent to the non-special-shaped display area 100 b. The portion of the shaped lcd panel 100 corresponding to the shaped display area 100c has a curved edge, and the curved edge is disposed at a corner of the shaped lcd panel 100 to enhance the appearance of the shaped lcd panel 100, such as the curved edge 1003. The curved edge may be at least one of a circular arc edge, an elliptical arc edge, a drop-shaped edge, a circular edge, and an irregular curve.
The display region is provided with a plurality of sub-pixels 1001, and the plurality of sub-pixels 1001 are arranged in an array. Each subpixel 1001 is rectangular in shape and includes a red subpixel, a blue subpixel, and a green subpixel. Each sub-pixel comprises a pixel electrode, a common electrode, a light resistance unit and a corresponding liquid crystal layer. Three adjacent sub-pixels constitute one pixel. In the special-shaped display area 100c, the arrangement mode of the sub-pixels is limited by the curve edge of the special-shaped liquid crystal display panel 100, and the arrangement of the sub-pixels cannot keep the same regularity and repeatability as those of the non-special-shaped display area 100 c.
The irregular liquid crystal display panel 100 includes an array substrate (not shown), a color filter substrate (not shown), and a liquid crystal layer (not shown). The color film substrate is arranged opposite to the array substrate, and the liquid crystal layer is arranged between the array substrate and the color film substrate. The white light emitted by the backlight module is emitted out through the light-emitting surface of the color film substrate after being incident on the light-in surface of the array substrate.
In the traditional technology, in the process of low-temperature polycrystalline silicon, in order to improve the light leakage effect of a thin film transistor device, a light shielding layer is formed on a glass substrate and has a good light shielding effect so as to prevent the light emitted by a backlight module from causing the thin film transistor device to have leakage. In order to solve the sawtooth phenomenon of the special-shaped display area of the special-shaped liquid crystal display panel, the light shielding layer is subjected to new patterning design, and therefore picture optimization is carried out on the special-shaped display area with the sawtooth phenomenon.
Specifically, as shown in fig. 2, the array substrate includes a light shielding layer 1005, the light shielding layer 1005 is provided with a first opening 1005a corresponding to each sub-pixel 1001 located in the irregular display area 100c, the area of the first opening 1005a increases in a direction in which the irregular display area 100c points to the non-irregular display area 100b, so that the luminous flux of the irregular display area 100c incident to each sub-pixel 1001 from the array substrate increases in a direction in which the irregular display area 100c points to the non-irregular display area 100b, the effective light emitting area of the sub-pixel of the irregular display area 100c increases in a direction in which the irregular display area 100c points to the non-irregular display area 100b, the luminance of the sub-pixel 1001 of the irregular display area 100c increases in a direction in which the irregular display area 100c points to the non-irregular display area 100b, so that the sub-pixel near the edge (e.g. the curved edge 1003) of the irregular display area 100c is dark, the brightness of the sub-pixels in the special-shaped display area 100c close to the non-special-shaped display area 100b is gradually increased, the picture saw-tooth feeling existing in the special-shaped display area 100c during display is eliminated, and the user experience is improved. In addition, the light shielding layer plays a role in shielding the thin film transistor in the display area on the array substrate, and the working stability of the thin film transistor is improved, so that the display effect of the special-shaped liquid crystal display panel is improved.
In this embodiment, the light-shielding layer 1005 is a metal layer, which has better light-shielding effect than the black organic photoresist, and the process stability of obtaining the patterned metal layer as the light-shielding layer is better than the process stability of preparing the black matrix. The material for forming the light-shielding layer 1005 is at least one selected from molybdenum, aluminum, titanium, and copper. The light-shielding layer 1005 has a thickness of 200 to 800 angstroms, for example, 300 angstroms.
In this embodiment, the first opening 1005a is disposed corresponding to the middle of each sub-pixel 1001, so that the light-shielding layer can shield the thin film transistor formed subsequently, thereby preventing the thin film transistor from leaking electricity. The area of the first opening 1005a is smaller than that of each sub-pixel.
In this embodiment, in the same pixel, the area of the first opening 1005a of the light shielding layer 1005 corresponding to the sub-pixel 1001 increases in the direction that the special-shaped display area 100c points to the non-special-shaped display area 100b, so as to ensure the stability of the working performance of the thin film transistor device in the special-shaped display area 100, since the sub-pixel far away from the non-special-shaped display area 100b in the special-shaped display area 100c is closer to the curved edge, light is easily reflected repeatedly when the sub-pixel is closer to the curved edge, and the smaller the first opening 1005a near the curved edge is, the larger the light shielding area of the light shielding layer 1005 corresponding to the sub-pixel 1001 is, which is more favorable for preventing the thin film transistor from generating leakage current, thereby improving the display effect of the pixel.
In this embodiment, the shape of the first opening 1005a is the same as that of the sub-pixel 1001, which is more beneficial to improving the display effect of the special-shaped display area. For example, when the sub-pixel 1001 has a rectangular shape, the first opening 1005a has a rectangular shape. When the sub-pixel 1001 has a parallelogram shape, the first opening 1005a has a parallelogram shape.
In this embodiment, the array substrate further includes at least one thin film transistor (not shown) corresponding to each sub-pixel, an orthogonal projection of the thin film transistor on the array substrate is located in an orthogonal projection of the light-shielding layer 1005 on the array substrate, the color filter substrate includes a plurality of black matrixes (not shown), the black matrixes are corresponding to the thin film transistors, the black matrixes play a role of shielding the thin film transistors, and simultaneously, an orthogonal projection of the black matrixes on the array substrate is prevented from being overlapped with an orthogonal projection of the first opening 1005a on the light-shielding layer 1005 on the array substrate, and the black matrixes are prevented from reducing an effective light-emitting area of the sub-pixels, so that an aperture ratio of each sub-pixel 1001 is improved.
In this embodiment, the light-shielding layer 1005 is provided with a second opening 1005b corresponding to each sub-pixel 1001 of the non-special-shaped display area 100b, the area of the second opening 1005b is larger than the area of any one of the first openings 1005a, so that the effective light-emitting area of the sub-pixel 1001 of the non-special-shaped display area 100b is larger than the effective light-emitting area of any one of the sub-pixels of the special-shaped display area 100c, and the area of the light-shielding layer 1005 corresponding to each sub-pixel 1001 of the special-shaped display area 100c is larger than the area of the light-shielding layer 1005 corresponding to each sub-pixel of the non-special-shaped display area 100b, so that the light-shielding effect of the special-shaped display area 100c is better, which is beneficial to controlling the leakage current of the thin film transistor of the special-shaped display area 100c, and is beneficial to improving. In addition, the areas of any two of the second openings 1005b are equal, so that the aperture ratio of each sub-pixel of the non-irregular display area 100b is further improved.
The above description of the embodiments is only for assisting understanding of the technical solutions and the core ideas thereof; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
