Super fast response super twisted nematic liquid crystal display

摘要

The fast response super twisted nematic liquid crystal display (STN LCD) according to the present invention reduces the cell gap of the liquid crystal cell, secures high-speed response characteristics by using a liquid crystal material having low viscosity and high anisotropic refractive index. High-speed response that responds at about 80 msec or less to secure high frequency band voltage stability characteristics (threshold voltage characteristics) of liquid crystals by minimizing Vth variation between 300 Hz and 72 KHz of liquid crystal material. By driving the liquid crystal panel at a high frequency by using a controller and a random access memory for controlling the image display, the contrast reduction due to the frame frequency response phenomenon caused by the improvement of the fast response characteristic of the liquid crystal panel is improved, and the segment electrode driver Drive by driving with ASDM which sets the driving voltage of (Segment Driver) to 10V or less, By reducing the internal resistance of the internal electrolytic capacitor from 10Ω to 3Ω (100KHz reference), crosstalk due to the high frequency driving of the liquid crystal panel with the frame frequency higher than 300Hz is reduced.
