1. Application
This specification applies to a color TFT-LCD module, QD23HL02
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.

[Note]
(1) ADIM is control signal for Inverter's output Power to Back Light Lamp Bulb. Input Signal
should be able to control Amplitude of Inverter Output voltage. From 0V to 3.3V, Inverter
Output Voltage should be able to vary to control Brightness of Lamp from 80% to 120%
Luminescence variation.
(2) PDIM is PWM control input; i.e. for the given ADIM, this PDIM input should be able to
control Width of Voltage Burst of inverter output for Lamp Driving. This input can have two
type of input; Ordinary default setting will be DC level signal using Saw Tooth Wave control
for PWM duty control. The other setting is Duty Signal Input with 3.3V TTL specification.
These two method should be decided by 14th Pin input setting.
(3) 14 Pin is selection pin for PWM control method; if this pin is connected to GND, PDIM input of
13th Pin should have Logic Level Duty Signal for PWM control. If this is set to High or Open,
One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory! www.panelook.com

13th Pin should have DC level signal therefore the Inverter should have Saw Tooth Wave
Generator to generate internal PWM signal. Default setting is "Analog", means when it is "Not
Connected", 13th pin of PWM control should be have DC Level signal for PWM.
4-3-2. Lamp connector
Back Light Lamp Connectors and Pin Assignment are as follows.
Connectors attached to Lamp Lead : BHR-04VS-1(JST)

6-2. Backlight driving
The backlight system is a direct-lighting type with 6 U shape CCFT (Cold Cathode Fluorescent
Tube).
The characteristics of the lamp are shown in the following table.
Parameter Symbol Min. Typ. Max. Unit Remark
Lamp current range IL 4.7 5.2 5.7 mArms Note1
Lamp voltage VL 1780 Vrms
Lamp power consumption PL 9.3 Note2 IL=5.2mA
Lamp frequency FL 57 kHz Note3
Established starting voltage Vs 2350 Vrms Ta=25
2810 Vrms Ta=0 Note4
Lamp life time LL 50000 hour Lum Note5
ratio:100%
40000 hour Lum Note5
ratio:120%
Note1 Lamp current is measured with current meter for high frequency as shown below.
Note2
Note3
Calculated Value for reference ( IL V L)
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.
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.
Note5 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.
Note6 The performance of the backlight, for example life time or brightness, is much influenced
One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory! www.panelook.com

by the characteristics of the DC-AC inverter for the lamp. When you design or order the
inverter, please make sure that a poor lighting caused by the mismatch of the backlight and
the inverter (miss-lighting, flicker, etc.) never occur. When you confirm it, the module
should be operated in the same condition as it is installed in your instrument.

connector length)
