A display is created using “smart pixels.” A smart pixel is a pixel of a display that integrates the pixel pipeline as part of the pixel, rather than using separate integrated circuits. A smart pixel may be based on an integrated stack that includes light emitting elements, an external data contact for receiving digital data for that pixel, and also the pixel pipeline from the digital data to the light emitting elements.
