[0030] Since the lower surface of the light-shielding ink layer is provided with backlight shape alignment lines and display shape alignment lines, the display shape alignment lines can be used to identify and check whether the display module and the cover plate are misaligned, thereby improving production and assembly efficiency and improving product competitiveness. The backlight shape alignment lines and the display shape alignment lines are made of different materials and / or shapes, so that assemblers can clearly distinguish the backlight shape alignment lines and the display shape alignment lines, easily distinguish and identify them, and avoid making mistakes.

[0031] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0032] See also Figures 1 to 4, a liquid crystal display screen for identifying misalignment provided by the utility model, comprising a cover plate 1 and a display module 2, the display module 2 is arranged below the cover plate 1, a light-shielding ink layer 11 is arranged on the lower surface of the cover plate 1, the light-shielding ink layer 11 is provided with an IR hole hollow portion 12 and a camera hole hollow portion 13, IR ink is arranged at the IR hole hollow portion 12, a backlight shape alignment line 14 and a display shape alignment line 15 are arranged on the lower surface of the light-shielding ink layer 11, the backlight shape alignment line 14 corresponds to the shape contour of the backlight module, the display shape alignment line 15 corresponds to the shape contour of the display module 2, the backlight shape alignment line 14 and the display shape alignment line 15 are different in material or shape, or the backlight shape alignment line 14 and the display shape alignment line 15 are different in material and shape. Since the lower surface of the light-shielding ink layer 11 is provided with a backlight shape alignment line 14 and a display shape alignment line 15, the display shape alignment line 15 can be used to identify and check whether the display module 2 and the cover plate 1 are offset, thereby improving production and assembly efficiency and improving product competitiveness. The backlight shape alignment line 14 and the display shape alignment line 15 are made of different materials and / or shapes, so that the assembler can clearly distinguish the backlight shape alignment line 14 and the display shape alignment line 15, and easily distinguish and identify them to avoid making mistakes.

[0033] Furthermore, the material of the backlight shape alignment line 14 is white oil, and the material of the display shape alignment line 15 is the same as the material of the IR ink, so that the assembler can clearly distinguish the backlight shape alignment line 14 and the display shape alignment line 15, and easily distinguish and identify them to avoid mistakes.

[0034] Furthermore, the backlight shape alignment line 14 is a straight line, and the display shape alignment line 15 is an L-shape, so that the assembler can clearly distinguish the backlight shape alignment line 14 from the display shape alignment line 15, and easily distinguish and identify them to avoid mistakes.

[0035] Furthermore, there are four display shape alignment lines 15 , and the four display shape alignment lines 15 are respectively disposed at four vertices of the shape of the display module 2 .

[0036] Furthermore, the color of the backlight shape alignment line 14 and the display shape alignment line 15 are different. In the present embodiment, the color of the backlight shape alignment line 14 is white, and the color of the display shape alignment line 15 is gray-black, so that the assembler can clearly distinguish the backlight shape alignment line 14 and the display shape alignment line 15, and easily distinguish and identify them to avoid mistakes.

[0037] See also Figure 5As a further optimization scheme of Example 1, in this embodiment, a frame-shaped groove 16 is etched on the lower surface of the cover plate 1, and the outer dimensions of the frame-shaped groove 16 are larger than the outer dimensions of the display module 2. A liquid optical adhesive 3 is arranged between the cover plate 1 and the display module 2, and the liquid optical adhesive 3 is coated in the space enclosed by the frame-shaped groove 16. Since the frame-shaped groove 16 is etched on the lower surface of the cover plate 1, the frame-shaped groove 16 can be etched before the large cover plate 1 is cut, and its production efficiency is high, and the cost increased by the additional etching step is extremely low. Then, ink spraying is performed, and silk-screen printing is no longer used to avoid ink accumulation in the frame-shaped groove 16, and finally the large cover plate 1 is cut into multiple single cover plates 1. When assembling the single cover plate 1 and the display module 2, liquid optical glue 3 is applied on the lower surface of the cover plate 1, and then the cover plate 1 and the display module 2 are fitted together. Since the single-side distance between the display module 2 and the frame groove 16 is at least 0.2 mm, the excess liquid optical glue 3 can flow into the 0.2 mm gap. If there is any liquid optical glue 3 left, it can flow into the frame groove 16 to avoid overflow of the liquid optical glue 3, thereby reducing the wiping process and improving the assembly efficiency of the liquid crystal display, thereby reducing the manufacturing cost of the liquid crystal display and improving the competitiveness of the product.

[0038] Furthermore, the width of the frame-shaped groove 16 is 0.4 mm to 0.8 mm, the depth of the frame-shaped groove 16 is 0.3 mm to 0.4 mm, and the cross-sectional shape of the frame-shaped groove 16 is a trapezoid that is wide outside and narrow inside to prevent the liquid optical adhesive 3 from flowing out.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms.
