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.
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.
Note3 ) Do not make tv, th and thp fluctuate.
Note4) In case of using the long frame period, the deterioration of display quality, noise etc. may be occurred.
Note5) 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.
