Abstract: A pixel structure includes a light-emitting module, multiple sub-pixel circuits, and an internal driving circuit. The light-emitting module includes multiple sub-pixel light-emitting elements, and is disposed on a first plane. The multiple sub-pixel circuits are disposed on a second plane, and each of the multiple sub-pixel circuits is electrically connected with a corresponding one of the multiple sub-pixel light-emitting elements. The internal driving circuit is disposed on the second plane, and is electrically connected with one of the multiple sub-pixel circuits. The first plane is different from the second plane, and the multiple sub-pixel circuits and the internal driving circuit are located in a vertical projection projected by the light-emitting module onto the second plane.

Abstract: A display device has a substrate for disposing a display area having an array of pixels, and control circuits having shift registers and latches to provide image data and timing control signals to the pixels. The control circuits have signal lines electrically connected to a connection cable to receive therefrom data signals indicative of the image data and timing pulses indicative of the timing control signals. The connection cable is also configured to provide reference signals to the shift registers and latches in the control circuits. The data signals are digital signals having an amplitude range greater than the amplitude range of the reference signals. No driver IC is disposed on the substrate to process analog signals. Each of the pixels has three sub-pixels and each of the color sub-pixels has three color sub-areas configured to receive timing control signals from a different scan line.
