Led panel control methods and systems

A computer-implemented method for converting received Red-Green-Blue, RGB, video data into a Red-Green-Blue and a Fourth colour, RGBF, LED drive signal, the method comprising:

• receiving RGB video data representative of a video comprising a plurality of frames, each frame comprising a plurality of pixels, wherein, for each pixel of each frame of the video, the RGB video data defines a red, a green and a blue brightness for representing a colour and a brightness of the pixel;
• and
• generating a RGBF LED drive signal from the received RGB video data, wherein the RGBF LED drive signal is configured for driving one or more LED modules comprising a plurality of LED units, wherein each LED unit represents a pixel and comprises a Red LED, a Green LED, a Blue LED, and a Fourth-colour LED that is not the same colour as the Red, Green or Blue LEDs;
• wherein the generating further comprises:
• applying a control parameter to adjust a characteristic of the RGBF LED drive signal.
