A common community modification to fix this inverted logic involves adding a small signal diode like a 1N4148 to the circuit, converting it to direct control.
Use a digital multimeter on the display's original power supply unit (PSU) board to isolate a stable 12V or 24V supply line ( VINcap V sub cap I cap N end-sub

What is the of the LCD panel you are upgrading?
: This is the switch signal. It must be connected to a 3.3Vā5V signal to turn the backlight on. To achieve the performance listed in the datasheet,
The GYD-9E module typically comes in a 16-pin QFN package. The pinout is as follows:
