2-6. TIMING CONTROL IC (LZ9GG314)
(1) FEATURES
The LZ9GG314 is a timing control IC for TFT-LCD modules.
Applicable model: Modules using QVGA pixel digital driver
(1) Generates, by inputting the clock signal, horizontal synchronous
signal, and vertical synchronous signal, the following signals which
synchronize with them:
1) Source driver drive signals: CLK, SPL, SPR, LP, PS
2) Gate driver drive signals: CLS, SPS
3) Signal for generating common electrode drive signal: REV
4) Base signal generation signal: REVV0
(2) Capable of inverting the display screen upside down and horizon-
tally.
