Referring to fig. 10, fig. 10 is a schematic diagram comparing the solution of the present application before and after the improvement, wherein the reference H is the black border area after the improvement, and the reference K is the black border area before the improvement, it is obvious that the black border area after the improvement (the solution of the present application) is more uniform and is significantly narrower at the fillet position. From comprehensive perspective, the display effect in the technical scheme of the application is more beautiful. In addition, in order to highlight a better four-face area display effect in the technical scheme of the application, the overall thickness of the large plane (main body portion 321) of the display screen cover plate 320 in the scheme may be designed to be thicker as much as possible, for example, the thickness of a conventional CG cover plate is 0.55mm, and the display screen cover plate 320 may be 0.8mm or even 1.0mm in the scheme. Therefore, the whole machine is more prominent in the roundness of stress and the appearance of the four-curved surface.

The disadvantage of the prior art is that the glass based on the CG cover inner surface R6 has a stretching ratio of 7% -8% at the fillet position, so that the fit depth at the fillet position is constant under a certain CG cover, and the width of the black edge at the fillet position is much wider than that of the four sides (as shown in fig. 10), which makes it difficult for consumers with certain obsessions to accept such a positive display effect. Therefore, the scheme is based on the technical scheme that the CG cover plate is reasonably designed, the black edges at the four sides and the round corners of the front side are uniform in width, and the front side has a good four-curved display effect. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
