Abstract

The invention provides a thinning device and a thinning method. A carrying device is utilized to fix a display panel, a height adjusting device is utilized to adjust a distance between the display panel and etching liquid in a liquid bin, and a first substrate is thinned step by step by enabling the first substrate of the display panel to contact with the etching liquid; preliminary thinning is realized at a first thinning stage, quick thinning is realized at a second thinning stage, slight thinning is realized at a third thinning stage, in this way, defects on the first substrate are not completely etched by the etching liquid too early, so that defect amplifying is avoided; correspondingly, defects like concave points and scratches on the surface of the display panel can be eliminated without through an extra polishing process, so that the thinning process of the display panel is simplified, the problem of chippings caused by the polishing process can be avoided, product yield is increased, and display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thinning device and a thinning method. Background technique [0002] The development of liquid crystal display panels is changing with each passing day, and has become an indispensable part of people's lives. Due to its advantages of large viewing area, uniform and compact volume, low-voltage micro-power consumption, flat-panel structure, passive display, large amount of displayed information, easy colorization, no electromagnetic radiation and long life, the fields involved in liquid crystal display panels are also gradually expand. With the continuous update of technology and equipment, the display effect has been greatly improved, bringing great convenience to our life and work. [0003] With the development trend of light and thin in the market, the display panel needs to be thinned after the box alignment process. At present, the overall thinning process is carried out ...
