TIMING SPECIFICATION
<H-Sync/V-Sync+DE Mode>
<DE-Only Mode>
Note 1) If NCLK is fixed to "H" or "L" level for certain period while DE is supplied, the panel may be damaged.
Note 2) Please adjust LCD operating signal timing and FL driving frequency, to optimize the display quality.
Note3 ) Do not make tv, th and tvds fluctuate.
