Commercial Comment: High-Information Content Liquid Crystal Displays

Liquid Crystal Materials and Liquid Crystal Displays

Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex requirements of electro-optical effects and render the effects appl...

Driving matrix liquid crystal displays

Liquid crystal displays had a humble beginning with wrist watches in the seventies. Continued research and development in this multi-disciplinary field have resulted in displays with increased size and complexity. After three decades of growth in performance, LCDs now offer a formidable challenge to the cathode ray tubes (CRT). A major contribution to the growth of LCD technology has come from ...

High Speed and Wide Viewing Angle Liquid Crystal Displays

Submillisecond-response liquid crystal for high-resolution virtual reality displays.

We report a vertically-aligned liquid crystal display (LCD) device with submillisecond response time, high transmittance, and low operation voltage. The top substrate has a common electrode, while the bottom substrate consists of hole-patterned fringing-field-switching (FFS) pixel electrodes. A negative dielectric anisotropy LC is employed. In the voltage-on state, the LC directors are reorient...

Color and Luminance Management for High-Resolution Liquid-Crystal Displays

A new method of color management is described which takes advantage of the high pixel density achievable with TFTLCDs. In this method, a calibration 10-bit look-up-table can be loaded into the monitor and implemented as a 2x2 spatial dither block to provide a 10-bit color palette for 8-bit color drive. Other subpixel dithering techniques are also described for monochrome and color high-resoluti...
