Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display glass, in particular to a display glass which is convenient for grabbing labels. Background Art
[0002] At present, in order to improve the color deviation problem of liquid crystal display glass, many pixel electrodes of liquid crystal display glass in the prior art adopt a dual-domain structure. The dual-domain technology divides each pixel area into two domains. The liquid crystals in the two domains compensate each other, which greatly improves the optical performance of the liquid crystal display glass at a wide viewing angle. Electric fields with different directions can be generated in different areas within a pixel area, so that the liquid crystal molecules in different domains in the pixel area rotate to different directions to obtain a larger viewing angle. The structural schematic diagram of the dual-domain pixel area of the existing liquid crystal display glass shows that the pixels are designed to be bent strips. During the full bonding of the display module and the assembly of the backlight, the device needs to grasp the display edge of the glass to identify the alignment. However, in this structure, since the outermost edge of the display area is a non-straight edge, it is not easy for the device to grasp the mark and align. Utility Model Content
[0003] The utility model aims to overcome the shortcomings of the prior art and provide a display glass which is convenient for grabbing labels.

[0006] In one of the embodiments, the groove is located at the center of the inner cavity of the BM layer, and the inner diameter of the groove body is between 3um and 10un.
[0007] In one embodiment, the BM layer covers the lower end of the glass layer, and the glass layer is a color filter substrate.
[0008] In one of the embodiments, the routing of the slot body is designed along the shape of the BM layer.
[0009] In one embodiment, the metal wiring covers the entire slot, and the color of the metal wiring is non-transparent.
[0010] In one of the embodiments, the retracted positions of the display glass are located at the four corners of the front side of the display glass, and the light transmittance of the glass layer is 95%.
[0011] In one of the embodiments, an optical adhesive is disposed between the glass layer and the BM layer, and the optical adhesive has a light transmittance of 98%.
[0012] In one of the embodiments, the diameter of the metal trace is the same as the diameter of the groove, and the metal trace only contacts the BM layer.
[0013] In one embodiment, the metal wiring is formed by winding and spirally weaving a plurality of metal wires.
[0014] In one of the embodiments, the BM layer is prepared by using an exposure process.
[0015] Compared with the prior art, the utility model has at least the following advantages:
[0016] The utility model discloses a display glass that is easy to grasp a label, and the outer edge of the BM is designed to be inwardly designed with a glass outer shape edge, and a groove is opened in the middle of the BM layer with a groove width of 3um to 10um, which is not easily visible to the naked eye from the appearance of the product, and the metal routing design on the glass layer (array substrate) corresponding to the groove can completely cover the groove, so the appearance display is non-transparent and the risk of light leakage can be reduced. In addition, the BM adopts an exposure process with high relative position accuracy. The probe of the device with fully laminated or assembled backlight can grasp the label and identify the BM groove or the outer straight edge of the BM as a reference point for alignment, thereby achieving a more accurate practice of grasping the label and alignment.
