Problems solved by technology

[0004] However, existing substrate thinning techniques still have their limitations
Once the substrate is thinned below a certain thickness, the substrate is prone to warp, and the thinning manufacturing process cannot be continued at this time, otherwise it will affect the overall flatness of the liquid crystal display panel and may cause fragments; for example, the existing Advanced substrate thinning technology, if using hydrofluoric acid (HF) solution, the glass substrate can only be etched from 0.5 millimeters (mm) to 0.3 millimeters (mm), and it can no longer be thinned, otherwise it will affect the flatness of the glass substrate cause adverse effects, the thinning effect of the prior art does have its limits

Abstract

The invention relates to a method for thinning a display panel device; the display panel device comprises a first substrate and a second substrate. The method for thinning the display panel device comprises the following steps: firstly, the first substrate is thinned and the thinned first substrate is supported by a bearing device, secondly, the second substrate is thinned. The manufacturing method of the invention can provides better thinning effect and can meet the requirement of mass production.

Description

technical field [0001] The present invention relates to a method for manufacturing a display panel device, in particular to a method for thinning a display panel device. Background technique [0002] Due to the continuous progress of optoelectronic technology in recent years, coupled with the entry of image display technology into the digital age, the liquid crystal display market has been vigorously developed. Liquid crystal displays are widely used in personal digital assistants (PDAs), mobile phones, camcorders, notebook computers, desktop monitors, On top of consumer communication or electronic products such as car displays and projection TVs, and gradually replacing traditional cathode ray tubes, it has become the mainstream in the display market. [0003] Among them, a key zero component of the liquid crystal display is the liquid crystal display panel. Nowadays, in addition to the pursuit of large size, the manufacturing technology of liquid crystal display panels i...
