Input Equivalent Circuits of Panel Block
To prevent static charges, protective diodes are provided for each pin except the power supplies. In addition,
protective resistors are added to all pins except the video signal input pins. All pins are connected to VSS with a
high resistance of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (Resistor value: typ.)
