| Pin / Signal | Description | Voltage (Typical) | | :--- | :--- | :--- | | | Differential pairs for receiving video data from the main SoC. Known signals include LVON and LVOP . | ~1.2 V differential | | VDD | Main digital power supply for the IC. | 3.3 V | | Pin 9 | Believed to be a power input requiring 3.3 V for normal operation. | 3.3 V | | GND | Ground return. | 0 V | | EEPROM Interface (I²C) | Pins (SCL, SDA) for communication with an external 24C32 EEPROM that stores panel timing and configuration data. | 3.3 V | | Output Control Pins | Generate logic signals for gate and source drivers. | Varies | | VCOM / AVCOM | Generates the reference voltage for the LCD panel's common electrode. | ~6 V (Should be approximately half of the analog supply voltage.) |
