7. WORKING THEOREM
A. DC-DC CONVERTER
This brick convert is the 110-220AC input voltage to 12V AND 3.3V output for invert use and
panel use and system controller use .
3.3V Out put at L804
VCC 12V In put at L803,F901
B. Scaling controller
The ADC is to convert RGB analog signal to digital signal that scaling chip can acknowledge.
The HSYNC input receives a logic signal and provides the frequency reference for pixel clock
generation.
The scaling IC is to converts the input signal ranging from VGA to SXGA into SXGA resolution
that panel can acknowledge.
GENERAL DESCRIPTION
The TSUM57AK is total solution graphics processing IC for LCD monitors with panel resolutions
up to SXGA.It is configured with a high-speed integrated triple-ADC/PLL, a high quality display
processing engine, and an integrated output display interface that can support RSDS panel
interface format.To further reduce system costs, the TSUM57AK also integrates intelligent power
management control capability for green-mode requirements and spread-spectrum support for EMI
management.
The TSUM57AK incorporates the world’s first coherent oversampled RGB graphics ADC in a
monitor controller system.The oversampling ADC samples the input RGB signals at a frequency
that is much higher than the signal source pixel rate. This can preserve details in the video signal
that ordinarily would be lost due to input signal jitter or bandwidth limitations in non-oversampled
systems. The TSUM57AK also incorporates a new Dynamic Frame Rate (DFR) generator for
the digital output video to the display panel that preserves the advantages of a fixed output clock
rate, while eliminating the output end of frame short-line.

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.
