1.0 GENERAL DESCRIPTION
1.1 Introduction
HB140WX1-300 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 14.0 inch
diagonally measured active area with WXGA resolutions (1366 horizontal by 768 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. Therefore, this module is suitable for
Notebook PC. The LED Driver for back-light driving is built in this model.
All input signals are LVDS interface compatible.
