摘要:
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.
