Problems solved by technology

Area discharge will damage the alignment film, or cause signal interruption or electrostatic discharge damage in thin film transistors and transparent electrodes such as indium tin oxide
The presence of dust particles or micro-discharges will cause yield degradation and poor display quality
In addition, all the above-mentioned modes use nematic liquid crystal, and its response time is at least a few milliseconds, thus limiting the application of dynamic image display on TV

Abstract

The invention discloses a liquid crystals composition and liquid crystal display, and in particular to blue phase liquid crystal composition and a LC display using the composition. The liquid crystal composition includes a first class including a highly polar compound and a second class including a highly conjugated liquid crystal compound. The blue phase liquid crystal display device includes first and second substrates each with a polarizer on the exterior surface and the blue phase liquid crystal composition sandwiched therebetween with and patterned electrodes on one of the substrates or both substrates. The patterned electrodes can be T-shaped, chevron or v-shaped, thin comb like shape and can also be flat or trapezoidal. The device outputs different light transmissions from the electrically controllable induced birefringence of the blue phase LC material for a low driving voltage, high transmittance blue phase liquid crystal display device.

Description

technical field [0001] The present invention relates to liquid crystal compositions, and in particular to methods, systems and devices for liquid crystal mixtures, which exhibit a blue phase and are used in polymer stabilizing compositions, and liquid crystal displays also include liquid crystal compositions. Background technique [0002] Liquid crystal display devices are widely used in the field of optical data processing. Modes include twisted nematic, super twisted nematic (STN), in-plane switching, vertical alignment, multi-domain vertical alignment (MVA), optical compensation Bending (optically compensated bend, OCB) and other techniques. All of these modes cause the orientation of the liquid crystal molecules to be controlled when a voltage is applied and changes the polarization direction and polarization state of the transmitted light. These changes are converted into light and dark contrast in a polarizing plate or the like for display. [0003] In order to cont...
