1. Application
This specification applies to a color TFT-LCD module, QD12TL0203.
2. Overview
This module is a color active matrix LCD module incorporating amorphous silicon TFT
(Thin Film Transistor). It is composed of a color TFT-LCD panel, driver ICs, control circuit,
power supply circuit and a backlight unit. Graphics and texts can be displayed on a 1280
800 dots panel with 262,144 colors by using LVDS (Low Voltage Differential Signaling) to
interface and supplying +3.3V DC supply voltage for TFT-LCD panel driving and supply
voltage for backlight.
The TFT-LCD panel used for this module has very high aperture ratio. A low-reflection
and higher-color-saturation type color filter is also used for this panel. Therefore, highbrightness and high-contrast image, which is suitable for the multimedia use, can be
obtained by using this module.
www.panelook.com
Optimum viewing direction is 6 o'clock.
[Features]
1) High aperture ratio, high-brightness.
2) Brilliant and high contrast image.
3) Small footprint and thin shape.
4) WXGA resolution (800 vertical by 1280 horizontal pixel array).
5) LVDS interface.
6) Low power consumption.
7) RoHS compliant
