Transflective 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...

High Brightness Twisted Nematic Transflective Liquid Crystal Display

P-156: Transflective Double Cell TN Liquid Crystal Display

Double cell Twisted Nematic (DTN) liquid crystal display is optimized for transflective liquid crystal displays, using MOUSE-LCD software. Two configurations of such DTN-LCD were simulated using a double and a single cell gap approach. DTN-LCD exhibits a high contrast ratio, wide viewing angles and achromatic (black/white) switching in both the transmissive mode and reflective mode. It also pos...

Transflective display using a polymer-stabilized blue-phase liquid crystal.

A wide view, submillisecond response, and single-cell-gap transflective display using a blue-phase liquid crystal (BPLC) is proposed. To balance the optical phase retardation between transmissive (T) and reflective (R) regions, in-plane protrusion electrodes are formed with different gaps in the two regions. This display exhibits reasonably high optical efficiency and well matched voltage depen...

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 ...
