Note 2) If ENAB is fixed to "H" or "L" level for certain period while NCLK is supplied, the panel displays black with some
flicker.
Note 3) If NCLK is fixed to "H" or "L" level for certain period while ENAB is supplied, the panel may be damaged.
Note 4) 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 conditions shown in 3.
Note5 ) Do not make tv, tvdh and tvds fluctuate.
If tv, tvdh, and tvds are fluctuate, the panel displays black.
Note6) In case of using the long frame period, the deterioration of display quality, noise etc. may be occurred.
Note7) 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.
