1.OVERVIEW
CLAA201WA04 is 20.1”(51.11cm) color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module composed of LCD panel, LVDS driver ICs, control circuit and backlight(CCFL, 4 tubes). By applying 8 bit digital data (6bits+Hi-FRC), 1680×1050, drived by 5 voltages,16.7M-color images are displayed on the 20.1” diagonal screen. The module structure is fixed by iron frame,without the inverter for the backlight. Interface of data and control signals is typ.General specification are summarized in the following table:

[Note]
*1) The relative temperature and humidity range are as below sketch, 90%RHMax. (Ta 40 ) *2) The maximum wet bulb temperature 39 (Ta 40 ) and without dewing.
*3) If you use the product in a environment which over the definition of temperature and humidity too long to effect the result of eye-atching.
*4) Product life-time related to lamp current, pls operate the production follow statement at page 9 CN2, 4 (BACKLIGHT)
*5) The testing conditions are according to IEC 1000-4-2 specification VESDt By using contact-mode to discharge each pin of the connector. VESDc By using contact-mode to discharge the module.
*6) If you operate the product in normal temperature range, the center surface of panel should be under 60 . 
Humidity 85%RH without condensation. Relative Humidity 90% (Ta 40 )
Wet Bulb Temperature 39 (Ta 40 )
*7) When lamp current over the definition of absolute maximun, product life-time will decay rapidly or operate unusual. If lamp current is under 3.0mA, the lamp could be abnormal-starting.
If for special request testing,then the minimun value 
of current is
2mA.It is not to promise product life-time and lighting in normally situation. 
*8) Delayed discharge time test condition: Starting lamp voltage = 1700 Vrms
Before test TD, lamp should operate at least
1min. , and lamp current should follow typical lamp current specification. To place panel at room temp. (25+/- 2 ) below for 24hr, and then to measure TD with the same starting lamp voltage in dark room.

[Note] Inverter vender : Sumida, model : IV50167/T
If the waveform of light up-driving is asymmetric, the distribution of mercury inside the lamp tube 
will become unequally or will deplete the Ar gas in it. Then it may cause the abnormal
phenomenon of lighting-up. Therefore, designers have to try their best to fulfill the conditions under the inverter designing-stage as below:

*2) a. Frequency in this range can make the characteristics of electric and optics maintain in +/- 10% except color coordinates.
b.Frequency in 50~60kHz can make characteristics of electric and optics better.
c.Frequency in 45~75kHz won’t damage the lifetime and reliability of lamp.
d. Lamp frequency of inverter may produce interference with horizontal(or vertical)
synchronous frequency,and this may cause horizontal beat on the display.Therefore,
please adjust lamp frequency, and keep inverter as far from module as possible or use 
electronic shielding between inverter and module to avoid the interference.
*3) Definition of the lamp life time
a.Luminance (L) under 50% of specification.
b.Starting Lamp Voltage: over130% of the initial value. Ta=25 *4) The condition of Turn-on and Turn-off operation is as below:
a.Lamp current is 7.0mA
b.Frequency is 10 sec.(on)/10 sec.(off)
c.Repeat it for 100 thousand times
