Embodiment 1

[0033] Such as Figure 5 , Figure 6 As 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, and the ink covering part 2 extends To the side 16, part or the whole side 16 is covered. The ink covering portion 2 forms an ink shading area 24 (invisible area), and four dividing lines L1, L2, L3, L4 are marked in the figure; wherein between the dividing lines L1 and L2, between the dividing lines L3 and L4 are the ink shading areas 24 (invisible area); between the boundary lines L3 and L2 is a transparent visible area 13 . The 3...

Embodiment 2

[0040] A method for manufacturing a mobile terminal 3D glass cover of the present invention, the mobile terminal 3D glass cover described in this embodiment has the same structure as the mobile terminal 3D glass cover described in Embodiment 1, as Figure 7 As shown, it is achieved through the following steps:

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

[0042] Process 2. Production of the white ink layer 22: on the basis of process 1, spray white photosensitive ink on the bottom surface of the 3D glass cover plate body 1, the inner chamfer surface 161 and the surface of the vertical surface 162, and then expose it by UV light. After developing and etching, the white ink layer 22 is obtained.

[0043] Process 3. Production of black ink layer 23: on the basis of process 2, spray a la...

Abstract

The invention relates to a 3D (Three-dimensional) glass cover plate for a mobile terminal and a manufacturing method thereof. The 3D glass cover plate for the mobile terminal comprises a glass cover plate body (1) and a printing ink covering part (2) which is arranged at the bottom surface (15) of the glass cover plate body (1); the glass cover plate body (1) comprises a flat panel part (11) and a 3D bending part (12) which is positioned on the edge; a transparent visible area (13) is enclosed in the centre of the printing ink covering part (2); the glass cover plate body (1) comprises a top surface (14), a bottom surface (15) and side surfaces (16) which are used for connecting the top surface (14) and the bottom surface (15); the printing ink covering part (2) extend to the side surfaces (16) to cover part or the whole of the side surfaces (16). According to the 3D glass cover plate for the mobile terminal, the chromatic aberration between an inner chamfer surface and a vertical lifting surface between the transparent visible area, and a decorating ring of the mobile terminal or a middle frame is avoided; a thorough problem is solved. The manufacturing method for the 3D glass cover plate for the mobile terminal provided by the invention is wide in application range; the problem about a mass production process of the 3D glass cover plate with four bent surfaces is solved.

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...
