TFT- LCD Operating mechanism
The structure of TFT-LCD is that Liquid Crystal is being filled between C/F Glass & TFT Glass. One Pixel consists of 3 sub-Pixels(R,G,B) and according to the number of the pixels, Display Resolution (SVGA,XGA,etc) is determined. The TFT Matrix consists of Data Line(Carrying display data signal),Gate Line(Carrying signal for turn On/Off the TFT).Each TFT, on each sub-pixel, controls the amount of Applying Voltage between C/F glass electrode & TFT glass electrode for the Liquid Crystal. The Applying Voltage changes the Direction of Liquid Crystal which changes direction of the Light. Transmittance rate of the Polarized Light, polarized by Polarizer, is controlled by Applying Voltage. As a conclusion, Displayed Light is now under-control of Display Data Signal. Light(CCFL lamp) Polarizer is a filter which polarize the light to one direction.

Guidance of handling Color TFT LCD Module
Color TFT LCD Module is very sensitive both electrically and physically.Users, therefore, are requested to follow the "Guidance of handling color TFT LCD Module" on the followings. 1
Be careful not to make scratch on the polarizer.
5
High temperature & high humidity reduce the life-time.
- Surface of polarizer is soft and can be physically damaged easily. - Please do not touch, push or rub polarizer surface with materials over HB hardness. 2
- LCD is not proper to be used at high temperature and high humidity. - Please keep specified temperature and humidity condition. 6
Keep clean the surface.
Keep out of Corrosive Gas.
- Please wear rubber glove when touch the surface of LCD screen. - Please use soft and anti-static material with n-Hexane as cleaner. 3 Keep out of water. - Water on/in the LCD may cause electrical short or corrosion. - Please wipe out or dry water carefully. 4
- Corrosive gas effect the polarizer and the circuit chemically and cause defects accordingly.
7
Electrostatic discharge can make damage
Prevent swift Temperature & Humidity change.
- There are electro-static sensitive components such as CMOS in LCD Module. - Please earth human body when handle the LCD.In addition, please do not touch the interface connector pin with bare hand. Do not operate for a long time under 8
the same pattern.
- Operating LCD for a long time under the same pattern can cause image persistence and can damage it. - Please follow following guidance. 1. Turn the power off when do not use. 2. Change the pattern periodically. 20
- Swift temperature and/or humidity change can make dew or ice which cause nonconformance such as malfunction.
