Notes:
Refer to “Timing Chart” below. If DE is fixed to “H” or “L” level for certain period while NCLK is supplied, the panel displays black w/some flicker.
If NCLK is fixed to “H” or “L” level for certain period while DE is supplied, the panel may be damaged. Please adjust LCD operating signal timing and FL
driving frequency, to optimize the display quality. There is a possibility that flicker is observed by the interference of LCD operating signal timing and
FL driving condition (especially driving frequency), even if the condition satisfies above timing specifications and recommended operating condi-
tions. Do not make tv, tvhd and tvds fluctuate. If tv, tvhd, and tvds are fluctuate, the panel display black. In case of using the long frame period, the
deterioration of display quality, noise, etc. may be occurred. NCLK count of each Horizontal Scanning Time should be always the same. V-Blanking
period should be ‘n’ X “Horizontal Scanning Time”. (n:integer) Frame period should be always the same.
