The high positive voltage (VGH, up to +30V) and the negative voltage (VGL, down to -7.5V) are generated internally using a (using external flying capacitors). Modern panels require these voltages to control the switching elements of individual pixels. | Pin | Nearby Component | Value |
: Counting progresses counter-clockwise around the perimeter of the package starting from the Pin 1 marker, down the left side, across the bottom, up the right edge, and closing along the upper margin. If VGHcap V sub cap G cap H

If you are currently working on an electronics repair project and need help taking the next step, I can assist you. Let me know:
When viewing the IC from the top, always identify the index mark at pin 1 (top-left) before routing – rotating the pinout 90° is the most common assembly error.
