1.0 GENERAL DESCRIPTION
1.1 Introduction
HT185WX1-300 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 18.5 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 16.7M colors. The TFT-LCD panel used for this
module is adapted for a low reflection and higher color type.

Notes : 1. The supply voltage is measured and specified at the interface connector of LCM.
The current draw and power consumption specified is for VDD=5 0V, Frame rate=75Hz and
VDD 5.0V, rate 75Hz
Clock frequency = 95MHz. Test Pattern of power supply current
a) Typ : Color Bar pattern
b) Max : Skip Sub Pixel Pattern
2. Duration of rush current is about 2 ms and rising time of VDD is 520 s 20 %
3. The lamp frequency should be selected as different as possible from the horizontal
synchronous frequency and its harmonics to avoid interference, which may cause line flow on the display
4. The voltage above this value should be applied to the lamps for more than 1 second to start-up. Otherwise the
lamps may not be turned on.
5. Calculated value for reference (VL IL) 4(channel) excluding driver loss. (LED Light bar: 13S4P)
