Novel optical heater and preparation method thereof

Abstract

The invention discloses a novel optical heater and a preparation method thereof. The novel optical heater comprises ITO conductive glass, wherein two opposite sides of the ITO conductive glass are respectively provided with an electrode strip mechanism; the electrode strip mechanism comprises an A-type low-temperature curing conductive copper glue, a B-type low-temperature curing conductive copperglue and a tin-plated white copper sheet, wherein the A-type low-temperature curing conductive copper glue, the B-type low-temperature curing conductive copper glue and the tin-plated white copper sheet are fixed on the surface of the ITO conductive glass from bottom to top; the problems that when a prior electrode strip is solidified, the required temperature is high, the coating layer of the heating glass is easy to change, the square resistance value is shifted, the square resistance value is increased, the heating power of the heating glass is reduced, and the heating effect is insufficient to the effect of the expected design; and meanwhile, the deviation condition of the square resistance value has no effective linear rule for carrying out pre-judgment which seriously affect the quality reliability of the product are solved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a novel optical heater and a preparation method thereof. Background technique [0002] At present, liquid crystal display occupies most of the market in the display industry. Liquid crystal display is an electronic display terminal product, which is mainly composed of liquid crystal panel, backlight, structural parts, circuit control board and so on. Liquid crystal display is a passive display technology, which needs to realize the selective transmission and color realization of the backlight by controlling the deflection direction of the liquid crystal molecules in the cell. The crystallization point of liquid crystal molecules is around -45°C, and the deflection rate of liquid crystal molecules will decrease significantly at low temperatures below -20°C, resulting in slower switching of display screens. Therefore, in the field of display, it is common to add a heating dev...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new type of optical heater and its preparation method, which solves the problem that when the traditional electrode strips are solidified, the required temperature is high, which easily causes the coating layer of the heated glass to change, resulting in the offset of the square resistance value, the square The larger the resistance value, the lower the heating power of the heater glass, and the heating effect is not as good as the expected design effect. At the same time, there is no effective linear law to predict the deviation of the square resistance value, which seriously affects the quality and reliability of the product.
