LC320WXE

Product Specification

1. General Description

The LC320WXE is a Color Active Matrix Liquid Crystal Display with an integral External Electrode F luorescent
Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally b lack mode. It has a 31.51 inch diagonally measu red
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in Hor izontal stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray sca le signal for each dot,
thus presenting a palette of more than 16.7M(6bit+AFRC) colors.
It has been designed to apply the 8-bit 1-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

4. The maximum operating temperatures is based on the test condition that the surface temperature

of display area is less than or equal to 68°C with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of

Note

The design of the inverter must have specifications for the lamp in LCD Assembly.
The electrical characteristics of inverter are based on High-High Driving type.
The performance of the lamps in LCM, for ex am pl e life time or bright ne ss, is extremely influe n ce d by th e
characteristics of the DC-AC inverter. So, all the parameters of an inverter should be carefully designed so
as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the
lamp and the inverter (no lighting, flicker, etc) has never been occurred. When you confirm it, the LCD–
Assembly should be operated in the same condition as installed in your instrument.
※ Do not attach a conductive tape to lamp connecting wire.
If you attach conductive tape to the lamp wire, not only luminance level can be lower than typical one but
also inverter operate abnormally on account of leakage current which is generated between lamp wire and
conductive tape.

1. Specified values are defined for a Backlight Assembly.( IBL : 10 lamp, 6.5 mA/Lamp)

2. Operating voltage is measured at 25 ± 2°C(after 2hr.aging).The variance range for operating voltage
is ± 10%.

3. The Striking Voltage (Open Lamp Voltage) [ Vopen ] should be applied to the lamps more than Striking
time (S
Otherwise, the lamps may not be turned on. The used lamp current is typical value.
When the Striking Frequency is higher than the Operating Frequency , the parasitic capacitance
can cause inverter shut down, therefore It is recommended to check it.

4. Lamp frequency may produce interference with horizontal synchronous frequency.As a result this may
cause beat on the display. Therefore, lamp frequency shall be away as much as possible from the
horizontal synchronous frequency and its harmonics range in order to prevent interference.
There is no reliability problem of lamp, if use out of range of operation frequency (61kHz~65kHz) on CAS

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn

6. Maximum level of power consumption is measured at initial turn on.

Typical level of power consumption is measured after 2hrs aging at 25 ± 2°C.

7. The life time is determined as the time at which brightness of the lamp is 50% compared to that of initia

value at the typical lamp current on condition of continuous operating at 25 ± 2°C, based on duty 100%.

8.The output of the inverter must have symmetrical(negative and positive) voltage and current waveform

(Unsymmetrical ratio is less than 10%). Please do not use the inverter which has not only unsymmetric
voltage and current but also spike wave.

※ We recommend not to be much different between PWM duty and Iout duty .

10. The Cable between the backlight connector and its inverter power supply should be connected directly
with a minimized length. The longer cable between the backlight and the inverter may cause the lower
luminance of lamp and may require more higher starting voltage ( Vs ).

4. These pins are used only for LGD (Do not connect)

5. Specific pin No. #30 is used for “No signal detection” of system signal interface.
It should be GND for NSB (No Signal Black) while the system interface signal is not.
