Description Of Block Diagram - LG FLATRON E2041T Service Manual

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 148MHz in E2041T case(28MHz to 148MHz In W2246S 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 1920 X
1080 resolution signal and outputs 8-bit R, G, B signal to transmitter.
2. Power Part.
This part consists of the one 3.3V, and one 1.2V regulators to convert power which is provided 5V in Power board.
5V is provided for LCD panel and micom in E2041T case .
Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided for IC in the main board.
Boost converter of LED block converters DC20V to DC50V and operates back-light LED strings of module in
E2210 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.
