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.
