1. Introduction And General Specifications
Liquid crystal Displays (LCDS) have widely used in many applications such as industrial measurements,
office mechanisms, and household electronic–equipment etc. LCM (LCD Module) integrates with LCD and
driving circuit that is easily to be interfaced by user. This LCM contains a standard built-in dot –matrix font
set.
1.1Applications of LCM 1.2 Features of LCM
Telephone Compact, thin and light
Facsimile mechanism Wide view angle
Electronic Typewriter Low power consumption
Word processor High contrast image
Electronic memo pads Wide operating temperature
Remote controller High reliability
