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.
