Driver circuit for and method of driving an emissive video matrix display

摘要

In accordance with one aspect of the present invention, what is provided is a method for displaying an image using an active matrix display of picture elements that radiate light in response to the application of electrical power. In this method, a display mode is selected from at least a first and a second mode. The image is presented on the display when the first mode is selected and the image is presented in a modified form when a second mode is selected. The image is modified so that presenting the image in the second mode consumes less power than presenting the image in the first mode. In another aspect what is provided is an image display driver for a matrix display of picture elements that radiate light in response to the application of power. The driver has a signal processor for receiving an image and processing the image for presentation on the display in accordance one of at least a first mode and a second mode. The signal processor modifies the appearance of the image as presented in the second mode so that the presentation of the image in the second mode consumes less power than the presentation of the same image in the first mode. A device controller is provided. The device controller determines display mode for displaying the image and generating a display mode selection signal. The signal processor processes the image in a mode indicated by the display mode selection signal.
