1.0 GENERAL DESCRIPTION

1.1 Introduction

HX121WX1-110 is a color active matrix TFT LCD module using amorphous silicon TFT's

(Thin Film Transistors) as an active switching devices. This module has a 12.1 inch

diagonally measured active area with WXGA resolutions (1280 horizontal by 800 vertical

pixel array). Each pixel is divided into RED, GREEN, BLUE dots which are arranged in

vertical Stripe and this module can display 262,144 colors. The TFT-LCD panel used for this

module is a low reflection and higher color type.
