Problems solved by technology

[0006] However, the light source of the existing bistable liquid crystal display 40 is an external ambient light source, so when the intensity of the external ambient light source is insufficient, the bistable liquid crystal display 40 cannot effectively display the picture.
In addition, most books usually have black text with a white background, so when applying this technology to e-books, in order to facilitate readers to adapt to e-books, the design of the liquid crystal display should preferably be black / white dual-color display to meet the needs of readers. Traditional reading habits, but the existing bistable liquid crystal display 40 is mainly based on two-color display such as red / black, green / black, or blue / black, so the existing bistable liquid crystal display 40 cannot meet the aforementioned requirements

Embodiment Construction

[0016] Please refer to image 3 , image 3 It is a schematic diagram of the bistable liquid crystal display 60 of the present invention. Such as image 3 As shown, the bistable liquid crystal display 60 includes a liquid crystal display panel 62, an optical regulator 64 is arranged on the upper side surface of the liquid crystal display panel 62, a lower polarizer 66 is arranged on the lower side surface of the liquid crystal display panel 62, and a backlight The module 68 is disposed on the lower side of the lower polarizer 66 for generating light to compensate the intensity of an ambient light source. Wherein, the liquid crystal display panel 62 further includes an upper substrate 70, a lower substrate 72, a conductive layer 76 disposed on the upper surface of the lower substrate 72, and a transparent conductive layer 78 (such as indium tin oxide) disposed on the lower side of the upper substrate 70. The surface, and a surface-stabilized cholesteric liquid crystal molecul...

Abstract

The LCD comprises a LCD faceplate, a lower polarized light plate, a upper polarized light plate, and a quarter wavelength plate. The LCD faceplate also comprises a upper base plate and a lower base plate. A conducting layer is setup on the surface of the lower base plate and a SSCT liquid crystal molecule layer is sealed between the upper base plate and the lower base plate. The LCD can be applied to places with diversified light intensities, providing comfortable reading color for users.

Description

technical field [0001] The invention relates to a bistable liquid crystal display, in particular to a semi-transmissive and semi-reflective bistable liquid crystal display in black and white mode. Background technique [0002] Surface stabilized cholesteric texture mode (SSCTmode) liquid crystal material is a liquid crystal material with multiple stable optical states and memory properties, which can be converted into Various desired optical states, and after the voltage is removed, the surface-stabilized cholesteric liquid crystal material maintains its optical state because the liquid crystals can be stabilized in a certain alignment. In addition, surface-stabilized cholesteric liquid crystal materials have the advantages of power saving, wide viewing angle, high brightness, and high contrast. Therefore, surface-stabilized cholesteric liquid crystal materials are often used in image display with low refresh rate and long-term use. components, such ...
