【Note 1】
◎ Please do not supply AVDD before VCC.
◎ It discharges and boost up voltage for TFT module on the basis of a DISP-signal
◎ It is not problem to set up DISP=L , AVDD=GND when VCC voltage is supplied
◎ Please don't set various signals to Hi-Z when VCC-voltage is supplied
◎ Don't change DISP signal into the state of H level When AVDD voltage is in the state of GND.
◎ The ON/OFF timing of LED Back Light is an example.
Dip Conditions for supply voltage
Sequences of supply voltage and signals
It drives Max-10 flames (about 0.2seconds) from change of DISP-signals by reasons that
It takes time for 9 flames while each processing operation.
Therefore, the display start is delayed for 10 flames and Ten or more frames needs to be
voltage maintained at the time of a display end.
Please do not change the DISP-signal level for 10 frames or less after the change.
in reason that those signals are CMOS input.
