Abstract
Description
technical field
[0001] The invention belongs to the production field of glass used in flat panel displays, and relates to a device and a control method for controlling the thickness uniformity of a glass plate during the production process of flat glass by using an overflow down-drawing process. Background technique
[0002] With the continuous advancement of science and technology, flat panel displays have begun to become popular. The flat glass used to display images is one of the key components of flat panel displays, and its quality directly affects the display quality of display devices. For example, in liquid crystal displays , especially for thin-film transistor display (TFT / LCD) glass, in the process of manufacturing such a display screen, various circuit patterns and thin-film transistors need to be formed on the surface of the glass. The formation of these patterns and devices is based on the use of The method similar to forming large-scale integrated circuits is f...
