1. General Description

The LC320WXE is a Color Active Matrix Liquid Crystal Display with an integral External Electrode Fluorescent
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 black mode. It has a 31.51 inch diagonally measured
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 vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot,
thus presenting a palette of more than 16.7M(true) 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.

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 example life time or brightness, is extremely influenced by

the 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 : 12 lamp, 7.75mA/Lamp)

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

3. The established starting voltage [

VS ] should be applied to the lamps for more than Striking time (S TIME)

for start-up. Inverter open voltage must be more than established starting voltage. Otherwise, the lamps may
not be turned on. The used lamp current is typical value.

4. Lamp frequency may produce interference with horizontal synchronous frequency. As a result, the 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.

5. The brightness of the lamp after lighted for 5minutes is defined as 100%.

is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.

T

S

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

6. Maximum level of power consumption is measured at initial turn on.
Typical level of power consumption is measured after 2hrs aging at 25 r 2¶C.

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

value at the typical lamp current on condition of continuous operating at 25 r 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 unsymmetrical

voltage and current but also spike wave.
Requirements for a system inverter design, which is intended to achieve better display performance,

power efficiency and more reliable lamp characteristics.
It can help increase the lamp lifetime and reduce leakage current.

a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within √2 ±10%.

* Inverter output waveform had better be more similar to ideal sine wave.

with a minimized length. The longer cable between the backlight and the inverter may cause the lower
