Note 1) Refer to TIMING CHART at page4 and LVDS specification (DS90CF364) by National Semiconductor Corporation.
Note 2) When ENAB is fixed to “H” level or “L” level after NCLK input, the panel is displayed as black. However, it may
be occurred a flicker on the display.
Note 3) When NCLK is fixed to “H” level or “L” level, the panel becomes white stage after several seconds.
Note 4) Do not change t1 and t3 values in the operation. When t1 or t3 is changed, the panel is displayed as black.
Note 5)
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).
