3. Basic
4. Y sustain B/D
: generates SUSTAIN,RESET waveform, Vsc(SCAN)voltage.
and supplies it Y DRIVER B/D.
* Composed with IPM,DIODE, electrolytic capacitor ,FET.
5. Control Board
: creates signal processing (Contour noise,reduction ISM,..)
and an order of many FET on/off of each DRIVER B/D with
R,G,B each 8bit input.
* Use 3.3V/5V 2 kinds of power .
