1. A method of manufacturing a display module, comprising the steps of: a) providing a substrate; and b) forming on the substrate using the same manufacturing process i) an image display having an array of addressable display pixels and pixel driver circuitry responsive to control signals and image data for driving the pixels; and ii) a digital signal processing circuit having an input interface over which image data and control signals are received; a frame buffer for storing image data and from which image data is read during a display refresh; a display matrix driver circuit for receiving image data from the frame buffer and supplies control signals to the pixel driver circuitry; a control circuit for coordinating storage, retrieval, and display operations, such that the display module is capable of display refresh independently of external control; and an image processing circuit for improving the visual perception of the displayed image.
