1. Application
This specification applies to a color TFT-LCD module, QD15XL16
3&:. 2CIG
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 10243768 dots panel with 16.2 million
colors by using the LVDS (Low Voltage Differential Signaling) interface, 6-bit+FRC driving method and
supplying +5V 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]
x A Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Filament Lamp
(CCFL) backlight system.
x TFT as the active element.
x Associated electronics (drivers, control circuits, etc)
x A metal frame

ޣNote1ޤ Lamp current is measured with current meter for high frequency as shown below.
ޣNote2ޤ Calculated Value for reference ( IL V L)
ޣNote3ޤ 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
synchronous to avoid interference.
ޣNote4ޤ 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.
ޣNote5ޤ Lamp life time is defined as the time when either Ԙ or ԙ occurs in the continuous
operation under the condition of Ta = 25͠ and IL =7.0 mArms.
Ԙ Brightness becomes 50 % of the original value under standard condition.
ԙ Kick-off voltage at Ta = 0͠ exceeds maximum value.
