*1 : As for the power sequence for backlight, it is recommended to apply above mentioned input timing.
If the backlight is lit on and off at a timing other than shown above, displaying image may get disturbed.
This is due to variation of output signal from timing generator when LVDS signal is changed from on to
off or vice versa, but has no harm to the module itself.
[Note] Do not keep the interface signal high-impedance or unusual signal when power is on.
Vcc-dip conditions
1) 2.5 V≦Vcc＜3.0 V
td≦10 ms
Under above condition, the display image should return to
an appropriate figure after Vcc voltage recovers.
2) Vcc＜2.5 V
Vcc-dip conditions should also follow the
On-off conditions for supply voltage
[Note 3] Typical current situation : 16-gray-bar pattern.
Vcc=+3.3V
Maximum current situation : Vcc=+3.6V
