| Abstract: | The STN-LCD employs a novel oriented layer,concels the residual image employs a novel driving waveshape, cancels the crosstalk. High contrast, fast response and low driving voltage are achieved in super twisted nematic liquid crystal dispays by using dixanes, halides, alkenyls, ethers and tolans.We describe a novel LCD driving methed(active addressing), which makes high-contrast, high-brigtness and video-rate STN-LCD displays possible by eliminating frame response. The display unit incorporates a temperature tracking circuit that automatically tracks the liquid crystal threshold voltage as it changes with temperature. |
