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.

Abstract: A pixel circuit includes a driving circuit, a lighting element, and multiple switching circuits. The driving circuit is configured to provide a driving current to a first node. A first terminal of the lighting element is coupled with a second node. A second terminal of the lighting element is configured to receive a system low voltage. The multiple switching circuits are coupled between the first node and the second node in a parallel connection, and configured to correspondingly receive multiple emission control signals and at least one grayscale control signal. During each frame, the multiple emission control signals provide multiple pulses, and the multiple pulses do not mutually overlapping in time sequence, so that the multiple switching circuits selectively couple the first node to the second node according to the multiple pulses and the at least one grayscale control signal.
