Therefore, the cover plate with this structure has a poor integrated black effect and cannot well hide the light-sensitive camera below the IR photosensitive hole, reducing the competitiveness of the product.

[0023] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0025] In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0026] The utility model provides a cover plate for improving the integrated black effect, which comprises a cover plate body, a black ink layer, an IR semi-transparent black ink layer, an LED lamp semi-transparent black ink layer, an infrared light-transmittable black photoresist ink, and a uniform white light ink. The black ink layer is disposed on the lower surface of the cover plate body located in the non-display area, and the black ink layer is provided with an IR photosensitive hole and an LED lamp hole in an avoidance manner. The IR semi-transparent black ink layer is disposed at the IR photosensitive hole; the LED lamp semi-transparent black ink layer is disposed at the LED lamp hole; the infrared light-transmittable black photoresist ink completely covers the lower surface of the IR semi-transparent black ink layer and partially covers the lower surface of the black ink layer; the uniform white light ink completely covers the lower surface of the LED lamp semi-transparent black ink layer and partially covers the lower surface of the black ink layer.
[0027] Since the IR semi-transparent black ink layer is disposed at the IR photosensitive hole, and the infrared light-transmittable black photoresist ink is covered on the lower surface of the IR semi-transparent black ink layer, visible light cannot pass through the infrared light-transmittable black photoresist ink, while infrared light can pass through. And under the action of the IR semi-transparent black ink layer, compared with directly disposing the infrared light-transmittable black photoresist ink without the IR semi-transparent black ink layer, its integrated black effect is better, so as to completely hide the light-sensitive camera below the IR photosensitive hole and improve the competitiveness of the product.
[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the drawings and embodiments. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The black ink layer 2 is disposed on the lower surface of the cover plate body 1 in the non-display area, and the black ink layer 2 is provided with an IR photosensitive hole and an LED lamp hole in an avoidance manner. The IR semi-transparent black ink layer 3 is disposed at the IR photosensitive hole; the LED lamp semi-transparent black ink layer 4 is disposed at the LED lamp hole; the infrared light-transmittable black photoresist ink 5 completely covers the lower surface of the IR semi-transparent black ink layer 3 and partially covers the lower surface of the black ink layer 2; the uniform white light ink 6 completely covers the lower surface of the LED lamp semi-transparent black ink layer 4 and partially covers the lower surface of the black ink layer 2. Since the IR semi-transparent black ink layer 3 is disposed at the IR photosensitive hole, and the infrared light-transmittable black photoresist ink 5 is covered on the lower surface of the IR semi-transparent black ink layer 3, visible light cannot pass through the infrared light-transmittable black photoresist ink 5, while infrared light can pass through. And under the action of the IR semi-transparent black ink layer 3, compared with directly disposing the infrared light-transmittable black photoresist ink 5 without the IR semi-transparent black ink layer 3, its integrated black effect is better, thereby completely hiding the light-sensitive camera below the IR photosensitive hole and improving the competitiveness of the product.
[0030] Please refer to Figure 3 , as a further optimized solution of Embodiment 1, in this embodiment, the transmittance of the infrared light wavelength of the infrared light-transmittable black photoresist ink 5 is about 70%-85%, and visible light cannot pass through the infrared light-transmittable black photoresist ink 5, so that only infrared light can pass through here, improving the integrated black effect.
[0031] Further, the thickness of the cover plate body 1 is 1 mm - 2 mm, the material of the cover plate body 1 is aluminosilicate glass or soda-lime glass, the thickness of the black ink layer 2 is 8 μm. The thickness of the infrared light-transmittable black photoresist ink 5 is 8 μm - 12 μm. The shape of the cover plate body 1 is circular.
[0032] Further, the edge of the upper surface of the cover plate body 1 is subjected to a light-scanning treatment to form a 2.5D arc surface, so as to form a 2.5D effect with a curvature.
[0033] Further, an optical adhesive 7 is disposed on the lower surface of the cover plate body 1, and the optical adhesive 7 covers the lower surface of the cover plate body 1 and the edge of a part of the black ink layer 2, and the lower surface of the optical adhesive 7 forms a smooth surface to avoid forming a step difference.
[0034] Further, an AG, AR, and AF treatment layer 8 is disposed on the upper surface of the cover plate body 1 to improve the anti-glare, anti-reflection, and anti-fingerprint effects.
