【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.

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.
