DESCRIPTION OF BLOCK DIAGRAM
1. Video Controller Part & Display Data Transmitter Part.(MST9151B) 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 135MHz. This part consists of the Scaler. The Scaler gets the video signal converted analog to digital, interpolates input to 1280 x 1024 resolution signal and outputs 8-bit R, G, B signal to transmitter. Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip"MST9151B" 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. Also, 5V is converted 3.3V and 2.5V by regulator. Converted power is provided for Scaler IC in the main board. 12V is provided for LCD Panel. 4. Inverter The inverter converts from DC12V to AC 700Vrms and operates back-light lamps of module.
