The board features two independent output ports. This allows it to drive two separate LED strips simultaneously, which is a standard requirement for many 20-inch and 24-inch monitors that use "top and bottom" or "left and right" lighting arrays. Constant Current Output
Unlike simple voltage regulators, the GYD-9E maintains a steady current flow. This is critical for LEDs because: gyd-9e datasheet
Allows the monitor to control the brightness level. GND: Ground connection. The board features two independent output ports
Prevents one side of the screen from being brighter than the other. gyd-9e datasheet
The aluminum-based design (in some variations) and efficient switching help the board stay cool during prolonged use. Wide Voltage Window
