  • Pixel control architecture for micro-LED micro-display with reduced transistor count
    Patent number: 11386835
    Abstract: In a display with subpixel LEDs, each pixel includes two subpixel LEDs controlled via a shared control circuit and switching element. Switching element logic allows one set of brightness control transistors to alternatively control two subpixels. The driving and control elements of a display backplane are organized into pixels units of four driving elements and three control elements. Each pixel may comprise two green subpixels controlled via the switching element. Alternatively, each pixel may comprise a white subpixel that only illuminates when the colored pixels are off; the green and white subpixels are controlled via the switching element.

  • Display element, system, and method
    Patent number: 11100892
    Abstract: A system may include a display element. The display element may include pixel groups. Each of the pixel groups may include: a first sub-pixel configured to output light of a first color; a second sub-pixel configured to output light of a second color; a third sub-pixel configured to output light of a third color; and a fourth sub-pixel configured to output light, wherein the fourth sub-pixel has a maximum brightness that is dimmer than a maximum brightness of each of the first sub-pixel, the second sub-pixel, and the third sub-pixel.
