3-2-4. Timing Generator (Q903)
This IC generates the timing to operate LCD panel, gamma
process ICs and alternation/sample & hold ICs. The timing
and mode are controlled by three line bus. For the input
signal, V sync, H sync and dot clock (synced with H sync)
signals are used. Figs. 3-2-4 and 3-2-5 are output timing
c h a r t s .
3-2-5. Electronic Variable Resistor 8 bit D/A
This circuit develops a DC voltage controlled by I
and the voltage controls input amplifier, gamma process
IC and alternation/sample & hold IC.
