1. Application
This specification applies to a color TFT-LCD module, QD23HL02
QD23HL02 Page 5
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 and power supply circuit
and a backlight unit. Graphics and texts can be displayed on a 1366 3 768 dots panel with 16.7 million
colors by using the LVDS (Low Voltage Differential Signaling) interface, 8-bit driving method and supplying
+12V DC supply voltage for TFT-LCD panel driving.
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, high-brightness and high-contrast image,
which is suitable for the LCD TV,HDTV and multimedia use, can be obtained by using this module.
[Features]
1) High-brightness
2) Brilliant and high contrast image.
3) High speed response
4) WXGA resolution. 16:9
5) LVDS interface.

6-2. Backlight driving
The backlight system is a direct-lighting type with 6 U shape CCFT (Cold Cathode Fluorescent
Tube).

Note1 Lamp current is measured with current meter for high frequency as shown below.

Note3 Lamp frequency may produce interference with horizontal synchronous frequency, and this
may cause beat on the display. Therefore lamp frequency shall be detached as much as
possible from the horizontal synchronous frequency and from the harmonics of horizontal
ޣ ޤ synchronous to avoid interference.
Note4 The voltage above this value should be applied to the lamp for more than 1 second to start-

up. Otherwise the lamp may not be turned on.
Lamp life time is defined as the time when either or occurs in the continuous
operation under the condition of Ta = 25 and IL = 6mArms.
Brightness becomes 50 % of the original value under standard condition.
Kick-off voltage at Ta = 0 exceeds maximum value.
The performance of the backlight, for example life time or brightness, is much influenced
