Connected Functions
to
Stabilizing
capacitor
Output from internal positive polarity operational amplifier when
the operational amplifier is ON (SAP2-0 = “001”, “010”, “011”,
“100”, and “101”). Stabilize by connecting to a capacitor.
Stabilizing
capacitor
Output from internal negative polarity operational amplifier when
the operational amplifier is ON (SAP2-0 = “001”, “010”, “011”,
“100”, and “101”). Stabilize by connecting to a capacitor.
GND or
external
resistor
Reference level for grayscale voltage generation circuit.
Connect to an external resistor when source driver is used to
adjust grayscale levels for each panel.
