Abstract

The invention provides an LCD device. By reasonably controlling thickness, dye molecules and liquid crystal materials of a liquid crystal layer, the LCD device has the advantages of being good in imaging effects, low in driving voltage and the like. The invention also provides a preparation method of the LCD device.

Description

technical field [0001] The present invention designs a display device, specifically, a LCD liquid crystal display device based on a doped liquid crystal material. Background technique [0002] Existing electronic paper display technologies mainly include: cholesteric liquid crystal bistable display, electronic ink electrophoretic display and two-color ball display and other technologies. [0003] Cholesteric liquid crystal bistable display technology uses polymer network to stabilize cholesteric liquid crystal, uses multi-domain texture scattering and network-stabilized zero-field stability of nematic phase transmission, and uses voltage-driven waveform technology to make liquid crystal enter multi-domain texture Or nematic texture to achieve bi-stability, and then realize the bright state in the power-on state and the dark state in the power-off state; or, using polymer dispersed liquid crystal or polymer dispersed cholesteric liquid crystal, through the dielectric of the l...
