Abstract

Provided is a low-power-consumption heat insulation and preservation strengthening process of an LCD module. The low-power-consumption heat insulation and preservation strengthening process is characterized in that the aim of local heat preservation of the module is achieved through the combined action of heat preservation grooves in a front shell of a metal structure and transparent heat insulation and preservation optical composite glue. The heat preservation grooves are located in the four corners of the front metal shell, the inner surfaces of the grooves are frosted surfaces, heat preservation materials are pasted in the grooves, and the heat conductivity is smaller than 0.03 W / m.K. The transparent heat insulation and preservation optical composite glue is prepared from nano SiO2 aerogel slurry, water-based acrylate resin, a dispersing agent, an initiator, other filter and the like. The heat conductivity of the transparent heat insulation and preservation optical composite glue is smaller than 0.09 W / m.K, and the light transmissivity of the transparent heat insulation and preservation optical composite glue is larger than 97%. According to the process, the display quality of the module at low temperature can be improved, low temperature power consumption can be reduced, and the low temperature failure occurrence rate can be lowered.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a technology for reinforcing a liquid crystal display in a low temperature state, in particular to a low power consumption heat insulation and heat preservation reinforcement process for an LCD module. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) needs to have the function of displaying at extremely low temperature in some special cases. The existing technology mainly expands the lower temperature limit of low-temperature work by installing a convenient and reliable heating system. Two heating schemes are mostly used: ITO transparent heating sheet technology and front screen glass and rear heating film co-heating technology. At present, the general-purpose heating film is a light-transmitting, heat-conducting, and electrically-conducting material with a certain resistivity. ITO is coated on a transparent heating sheet and then closely a...
