Problems solved by technology

[0007] The first purpose of the present invention is to provide a mobile terminal 3D glass cover, which solves the problems of white spots, missing teeth and other poor appearance on the edge of the existing 3D glass cover
[0008] The second object of the present invention is to provide a method for manufacturing a mobile terminal 3D glass cover, which solves the problem of the first layer of white photosensitive ink being sprayed on the straight-up surface in the exposure process of the existing 3D glass cover. When the white photosensitive ink is irradiated by UV light, the light is concentrated due to the refraction and reflection of the light at the edge of the 3D glass cover body, resulting in poor etching of the edge ink

Embodiment 1

[0034] Such as Figure 5 , Figure 6As shown, a mobile terminal 3D glass cover of the present invention includes a glass cover body 1 and an ink covering part 2 arranged on the bottom surface 15 of the glass cover body 1. The glass cover body 1 includes a middle flat part 11 and The 3D curved part 12 located at the edge, the middle of the ink covering part 2 encloses a transparent visible area 13, the glass cover body 1 includes a top surface 14, a bottom surface 15, and a side surface 16 connecting the top surface 14 and the bottom surface 15, the side surface 16 Including an inner chamfer surface 161, a straight rising surface 162 and an outer chamfer surface 163, the top surface 14 and the bottom surface 15 are connected by the outer chamfer surface 163, the straight rising surface 162 and the inner chamfer surface 161, and it is characterized in that: ink coverage The part 2 includes a common white ink layer 221 , and the normal white ink layer 221 extends to cover the in...

Embodiment 2

[0040] This embodiment is used to manufacture the manufacturing method of the mobile terminal 3D glass cover described in Embodiment 1, which is realized through the following steps: Figure 7 as shown,

[0041] Process 1. Production of the inner ink black frame: Spray a layer of black photosensitive ink on the bottom surface of the 3D glass cover body, then expose to UV light, develop and etch to obtain the inner ink black frame 21;

[0042] Process 2. Production of ordinary white ink layer: On the basis of process 1, spray ordinary white ink on the ink covering part 2 of the bottom surface of the 3D glass cover body, and the ordinary white ink extends to cover the inner chamfer surface 161 and the straight-up surface 162, then dry to form a common white ink layer 221;

[0043] Process 3, photosensitive white ink layer: on the basis of process 2, spray white photosensitive ink on the bottom surface of the 3D glass cover body, then expose to UV light, develop and etch to obta...

Abstract

The invention relates to a mobile terminal 3D glass cover and production method thereof. The mobile terminal 3D glass cover includes the main body of a glass cover (1), an ink overlay (2) mounted on the glass cover bottom (15). The lateral 3D surface (15) includes an inward bevel surface (161), a straight upward surface (162), and an outward bevel surface (163).).The glass cover invention has the characteristics as below: the ink overlay(2) includes a layer of common white ink coating (221), which extends to and covers the inward bevel surface(161) and straight upward surface (162). Because the common white ink coating is resistant to UV light, it shows no change when UV light shine on the 3D glass cover. The virtue of the coating protects the 3D glass cover by preventing appearance defect problems like scratches; white marks appearing on the 3D glass cover edge, and so on, improving product quality.

Description

technical field [0001] The invention relates to a 3D glass cover plate of a mobile terminal and a manufacturing method thereof. Background technique [0002] With the continuous popularization of smart mobile terminals and the continuous progress of society, users have higher and higher requirements on the appearance and performance of mobile terminals. A subversive revolution, the mobile terminal display screen is the window for consumers to sense the mobile terminal. For mobile terminals, the design of the display window is particularly important. The long-term use of 2D display screens and 2.5D curved glass display screens has been unable to bring more surprises to consumers. Consumers urgently need a breakthrough in display technology. Therefore, 3D curved display screens have emerged as the times require. [0003] The main structure of the 3D glass cover consists of two parts. One is the 3D glass formed by thermal bending. This glass is transparent and protects the fro...
