Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cover plates, in particular to a structure for measuring the angles of circular cover plate patterns and alignment lines. Background Art
[0002] At present, circular modules including circular functional panels and circular cover plates have been widely used. Among them, the circular functional panel can be a display panel or a touch panel. The circular functional panel is generally fixed to the circular cover plate by bonding. For the sake of aesthetics, some circular cover plate products have design scales or logos on the front, and in order to control the rotation angle after assembly, the back of the cover plate is often silk-screened with assembly alignment lines. In this way, it can be ensured that after assembly according to the alignment lines on the back, the pattern on the front can be in the correct angle and position of the product.
[0003] In order to ensure the yield rate, the prior art often performs a check on the alignment accuracy. Specifically, the alignment accuracy can be expressed by coaxiality and / or rotation. Since the front pattern layer of the circular cover cannot be directly seen from the alignment line on the back, it is impossible to directly achieve alignment. Therefore, it is impossible to use a three-dimensional instrument to measure the angle between the pattern on the front of the cover and the alignment line on the back, and thus it is impossible to determine the alignment accuracy of the product.

[0007] In one embodiment, the PET film is a transparent film, and the PET film is flush with one side edge of the alignment line.
[0008] In one embodiment, the PET film is vertically arranged, and one end of the PET film extends out of the cover plate body.

[0011] In one embodiment, the angle between one side edge of the PET film and the alignment point is the alignment accuracy between the pattern layer and the alignment line.
[0012] In one embodiment, a base color layer is silk-screened on the back of the cover body, and the base color layer is an opaque ink layer.
[0013] In one embodiment, the alignment line is screen-printed on the base color layer.

The alignment line 30 and the pattern layer 20 need to be located on the same straight line to ensure the fitting accuracy of the cover body 10 and the display module.
[0024] Reference Figure 2 The back of the cover body 10 is screen-printed with a base color layer 40, which is the main color of the cover body 10 and is an opaque ink layer. The base color layer 40 covers the back of the cover body 10. The alignment line 30 on the back of the cover body 10 is screen-printed on the base color layer 40, which is a non-black ink layer.
[0025] Further, refer to Figure 1 The pattern layer 20 on the front side of the cover body 10 is a scale or logo pattern.
