Description Of Block Diagram - LG Flatron L1511S Service Manual

1. Video Controller Part & Display Data Transmitter Part.(MST9011)
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 25MHz to 80MHz.
This part consists of the Scaler.
The Scaler gets the video signal converted analog to digital, interpolates input to 1024 x 768 resolution signal and
outputs 8-bit R, G, B signal to transmitter.
Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip "MST9011" by MSTAR.
This part transmit digital signal from the Scaler to the receiver of module.
2. Micom Part
This Part consists of EEPROM IC which stores control data, Reset IC 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 EEPROM.
3. Power Part
This part consists of the one 3.3V and one 2.5 regulators to convert power which is provided 5V in LIPS Board.
5V is provided for LCD Panel and Micom part.
Also, 5V is converted 3.3V and 2.5V by regulator. Converted power is provided for IC in the main board.
