Uniform heating device applied to liquid crystal display and liquid crystal display

Abstract

The invention discloses a uniform heating device applied to a liquid crystal display and the liquid crystal display. The uniform heating device comprises a first heating unit and a second heating unit. The first heating unit is fixed in a display area of a liquid crystal screen of the liquid crystal display. The second heating unit is fixed on the back surface of the liquid crystal screen. The heating surfaces of the first and second heating units face the liquid crystal screen. The first heating unit is a flexible resistive film which is shaped along the outer edge of the display area of the display screen. The second heating unit adopts indium tin oxide (ITO) transparent conductive glass for heating. The uniform heating device and the liquid crystal display have the advantages that a rational heating design is adopted, so that the shortcomings of display of the liquid crystal screen at low temperature can be overcome, the 6-minute overall performance display of the liquid crystal screen at -45 DEG C can be realized, and the requirements of the liquid crystal display in most environments can be met.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, in particular to a uniform heating device applied to a liquid crystal display and a liquid crystal display with the uniform heating device. Background technique [0002] As an important information display terminal, liquid crystal display is restricted by the characteristics of liquid crystal materials. In the environment of -30 ℃ or lower, the liquid crystal transforms into a solid critical state, the response time lags, and even loses the information display function. Especially in special environments, such as aviation, aerospace, exploration, etc., the normal operation of the liquid crystal display cannot be guaranteed at -45°C. How to ensure that the liquid crystal material can work normally at low temperature has become the primary task of the display designer. At present, it is mainly realized in two ways: one is to heat the ITO film built into the liquid crystal screen, which is com...
