1. An organic light emitting diode (OLED) display, comprising:
- a screen including a matrix of pixels, each pixel being comprised of a plurality of sub-pixels;
wherein the plurality of sub-pixels, include at least a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a night vision sub-pixel, wherein at least one of the four sub-pixels is inactive at any given time, and wherein the red sub-pixel is inactive in a night mode; and
wherein the night-vision sub-pixel is configured to have no significant emission in the infrared range.
