【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
in reason that those signals are CMOS input.
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.
