High-stability high-contrast liquid crystal display

Abstract

The invention relates to a high-stability high-contrast liquid crystal display. The display comprises a surface polarizer, a liquid crystal box and a bottom polarizer; the surface polarizer adheres tothe upper surface of the liquid crystal box, the bottom polarizer adheres to the lower surface of the liquid crystal box, alignment layers and glass substrates are arranged in the liquid crystal box,the alignment layers comprise an upper layer alignment layer and a lower layer alignment layer, and the glass substrates comprise an upper glass substrate and a lower glass substrate; the liquid crystal box sequentially comprises the upper glass substrate, a segmented electrode, the upper layer alignment layer, a liquid crystal layer, the lower layer alignment layer, a public electrode, and the lower glass substrate from top to bottom; clearance beads are arranged in the clearances of the liquid crystal layer, and boarder adhesive is arranged at the edge position between the upper glass substrate and the lower glass substrate. By means of the liquid crystal display, the solidification quality of the alignment layers can be improved, the anchoring force between the alignment layers and liquid crystal molecules can be enhanced to improve the stability of the display under a high-temperature environment.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display with high stability and ultra-high contrast. Background technique [0002] Because the liquid crystal display in the vertical alignment mode has good contrast and a background color close to the black state, it is favored by consumers, so the vertical alignment technology is widely used in various display fields. When it is used in the field of consumer electronics, because consumers generally use it indoors, the display effect of the LCD usually does not have much effect; and when the LCD is used in industrial electrical equipment, automobiles, or outdoor applications, the ambient temperature There are often great changes. When the ambient temperature is ultra-high temperature (over 80°C) or ultra-low temperature (lower than -30°C), due to the limitation of the characteristics of the liquid crystal material or the stability of the process, there may be no disp...

When it is used in the field of consumer electronics, because consumers generally use it indoors, the display effect of the LCD usually does not have much effect; and when the LCD is used in industrial electrical equipment, automobiles, or outdoor applications, the ambient temperature There are often great changes. When the ambient temperature is ultra-high temperature (over 80°C) or ultra-low temperature (lower than -30°C), due to the limitation of the characteristics of the liquid crystal material or the stability of the process, there may be no display or the display effect may change. Therefore, it is urgent to broaden the operating temperature range of liquid crystal displays to meet the application requirements in different temperature environments
