Abstract
A 2.4-inch reflective liquid crystal television display has been developed using an integrated liquid crystal matrix panel with 57,600 (240 × 240) picture elements. The panel incorporates a 240 × 240 array of active control elements fabricated on a silicon substrate.
The liquid crystal materials developed is the dynamic scattering type, and a nematic mixture of Schiff's bases and aromatic esters conductively doped with redox-type dopants for DC operation. Real time television images with a resolution high enough for a small screen can be clearly displayed on the panel without defects under ordinary ambient lighting.
Small size (118 × 114 × 38 W.H.D. mm), light weight (640 grams), and low power consumption (1.5 watt) are attained by using CMOS circuitry and high density mounting.
