parameter

1. The board supports a wide voltage input of 8V~20V; the typical value is 12V (when the power supply of the screen is 12V, the power supply of the board must be 12V)
2. The board has its own LED backlight drive circuit; it supports 9~25V voltage drive for small and medium-sized LED backlights.
3. The board has its own T-CON circuit, which can directly drive small and medium-sized LVDS/TTL LCD without T-CON, and supports PWM duty cycle to adjust the brightness of the backlight.
4. Resolutions of high-definition HDMI and analog RGB (VGA) adapted to PC graphics cards: 480×272, VGA, SVGA, XGA,
