LCD Driver IC with Key Input Function

Princeton Technology 

APPLICATION CIRCUIT 3

PT6555

Notes:

1. A capacitor must be added to the power line so that both the power supply voltage (VDD) rise time when power is applied and the power supply

voltage (VDD) fall time when power drops are at least 1ms.

2. DO is an open-drain output and requires a pull-high resistor between 1KΩ to 10KΩ. The pull-up resistor value must be appropriate to the capacitor

of the external writing so that the signal wave forms are not degraded.

3. R1=R2=R3, the resistance value must be decide by the LCD panel size.
