4. Circuit Description 

 

 

A/D converter 

This brick convert is the 110-220AC input voltage to 12V output for inverter use and 5V for panel , 
system and audio use and 3.3V,1.2V for controller use. 
 

 

INVERTER 

In order to drive the CCFLs embedded in the panel module, there is a half bridge inverter to convert by 
the controller.   
The input 12V up to hundreds of AC voltage output. 
The inverter is formed by symmetric in order to drive the separate lamp modules. 
The input stage consists of a PWM controller, half bridge inverter, and switching MOSFET to convert 
DC input into AC output. 
The output stage consists of a tuning capacitor, coupling capacitor, transformer, push-pull MOSFET 
pair to boost AC output up to hundreds of voltage. 
And one resister is serial to lamp for output voltage feedback. 
There are two signal to control the inverter which come from system. 
Logic “high” level which send to I901 is turn on the inverter.

 

BRI signal control brightness by DC level which was integral from PWM signal. 

 

I206 Scaler MSD2232L 

The MSD2232L is a highly integrated SOC for LCD/PDP DTV applications with resolutions up to 
SXGA/WXGA+. 
It is configured with an integrated triple-ADC/PLL,a multi-standard TV video and audio decoder, a 
DTV video and audio decoder, a video de-interlacer, a scaling engine, the MStarACE-3 color engine, a 
graphics engine, an 8-bit MCU and a built-in output panel interface.The built-in DTV decoder 
including transport streamde-multiplexer and MPEG-2 AV decoder are designed to support ATSC 
HD/SDTV program while handling ATSC CC and EPG. For analog TV,the MSD1226L receives 
NTSC/PAL/SECAM CVBS/S-Video and component video signals from various analog graphic & 
video sources.To further reduce system costs, the MSD1226L also integrates intelligent power 
management control capability for green-mode requirements and spread-spectrum support for EMI 
management.
