Display systems and methods with multiple and/or adaptive primary colors

A light-emitting display system comprising:

• a processor;
• and
• a display having a plurality of light-emitting elements (LEEs),
• wherein said LEEs comprise at least three basic primary colors and said display has a first color output at a first drive current,
• wherein said display system is configured to change said first drive current to a second drive current in a vertical sync frame, defined as a frame wherein a new image is shown on the display after receiving a vertical sync signal, such that the first color output can be changed to a second color output, and
• wherein said processor is configured to perform at least one mathematical operation for calculating the second color output dependent on said second drive current, and to perform at least one mathematical operation for adjusting color balance of said LEEs.
