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