Low-temperature uniform heating circular liquid crystal screen assembly method

Abstract

The invention discloses a low-temperature uniform heating method for a circular liquid crystal screen assembly. The circular liquid crystal screen assembly sequentially comprises heater glass (1), a heating material (2) plated on the heater glass and used for conducting electricity to generate joule heat and heating electrode strips (3) from bottom to top. The heater glass (1) is soda-lime float glass, the heating material (2) is indium tin oxide (ITO), and the heating electrode strip (3) is made of silver paste or copper. The pair of heating electrode strips (3) are used for carrying out symmetrical circular ring etching on the heating material surface so as to divide the heater into areas A, B and C; wherein a smooth structure is formed at the etched corner of the circular ring. According to the method, double electrodes are adopted, ITO on the surface of the heater is etched to change the trend of current, the temperature of the edge of the heater is higher than the temperature of the center, and the problem of low-temperature normal work of the circular liquid crystal display can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a low-temperature and uniformly heated circular liquid crystal screen component method. Background technique [0002] With the development of science and technology, the development of liquid crystal display has been very mature, and it has been widely used in people's life. Compared with ordinary liquid crystal displays, military airborne liquid crystal displays have a wider operating temperature. In a low-temperature environment, due to the physical characteristics of liquid crystals, the response time of liquid crystals is prolonged and cannot work normally. At present, a more mature solution is to heat the liquid crystal screen components so that they can heat up quickly and meet the requirements for normal operation at low temperatures. [0003] Most liquid crystal display modules have a rectangular structure, and use transparent rectangular conductive glass ...
