specific Embodiment approach 2

[0058] On the basis of the specific implementation mode 1, a specific method of thinning the area to be bent is proposed, the flow chart of which is as follows figure 2 As shown, it is referred to as the second specific embodiment, including:

[0059] Step S201: if image 3 As shown, a glass substrate 11 is provided, and the glass substrate 11 includes a plurality of first regions 111 sequentially arranged in a first direction, and the first regions 111 are used for binding display panels, adjacent to the first There is a region 112 to be bent between the regions 111 .

[0060] Step S202: if Figure 4 shown and Figure 5 As shown, a groove 12 is formed in the region to be bent 112 , where the sidewall 121 and the bottom surface 122 are perpendicular to each other. in, Figure 5 for Figure 4 A partial enlarged view corresponding to the position of the groove 12.

[0061] It should be noted, Figure 4 and Figure 5 The groove in the middle is only a schematic diagram ...

Abstract

The invention discloses a manufacturing method of a curved glass cover plate, by providing a glass substrate, the glass substrate includes a plurality of first regions arranged in sequence in a first direction, and the first regions are used for binding display The panel has a region to be bent adjacent to the first region; the region to be bent is thinned; and the region to be bent after the thinning process is bent and shaped to form a preset curved structure. The present invention reduces the energy consumption during hot bending of the glass by thinning the part to be bent in the bending area, makes the heating of the glass more uniform in the process of hot bending, reduces the risk of glass fragmentation caused by uneven heating during the heating process, and improves the The yield rate is improved, and at the same time, the requirements for equipment accuracy are reduced, thereby reducing equipment costs. The present invention also provides a curved glass cover plate with the above advantages.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a curved glass cover plate and a manufacturing method thereof. Background technique [0002] With the continuous advancement of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable and important display device for people today. tool. [0003] The main component of the display device to realize the display function is the display screen. Based on the requirements of the use environment of the display screen and the characteristics of high light transmittance of the glass material, the display screen needs to be fixed on the curved glass cover. For example, in the central control panel of a car, in order to meet the needs of the internal structure design of the car, more and more cars need to use a curved glass cover with a set s...
