1. Video Controller Part.

This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to the

digital video signal using a pixel clock.

The pixel clock for each mode is generated by the PLL.

The range of the pixel clock is from 28MHz to 108M in 20EN33T case(28MHz to 108M In 20EN33T CASE).

This part consists of the Scaler, ADC convertor, TMDS receiver and LVDS transmitter.

The Scaler gets the video signal converted analog to digital, interpolates input to 1600 X

900 resolution signal and outputs 8-bit R, G, B signal to transmitter.

2. Power Part.

This part consists of one regulator convert power from 19V to 5V.19V is provided by adapter.

5V is provided for LCD panel

Also, 5V is converted 3.3V by regulator.Converted Power is provided for IC in the main board.

Boost converter of LED block converters 19V to 41V and operates back-light LED strings of module in

20EN33T case.

3. MICOM Part.

This part is include video controller part. And this part consists of Flash IC which stores control data and the Micom.

The Micom distinguishes polarity and frequency of the H/V sync are supplied from signal cable.

The controlled data of each modes is stored in.

Only for training and service purposes
