Display driver and method for driving an emissive video display in an image displaying device
First Claim
1. A method for displaying an image using a matrix display of picture elements that radiate light in response to the application of power, the method comprising the steps of:
- selecting a display mode from at least a first and second mode;
presenting the image on the display when the first mode is selected, and, presenting the image in a modified form when a second mode is selected wherein the image is modified so that presenting the image in the second mode consumes less power than presenting the image in the first mode.

Abstract
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.

30. An image display driver for use in an imaging device having a matrix display of light emitting elements, and an image source, the image display driver comprising:
-
a set of element drivers adapted to control the illumination intensity of the elements;
a signal processor adapted to receive an image from the image source and processes the image for presentation on the display in accordance one of at least a first mode and a second mode with the signal processor modifying 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 adapted to determine a display mode condition and to generate a display mode selection signal based upon the display mode condition; and
a signal processor adapted to process the image in a mode selected by the mode selection signal.

34. An image display driver for use in an imaging device having a matrix display of light emitting elements and an image source, the image display driver comprising:
-
a set of element drivers adapted to control illumination intensity of the elements;
a signal processor adapted to receive an image from the image source and process the image for presentation on the display;
a device controller adapted to determine a display mode condition and to generate the display mode selection signal based upon the display mode condition; and
a display controller adapted to control the operation of the element drivers and to modify the operation of the element drivers in response to the display mode selection signal, the display controller being operable to control the element drivers in at least a first mode and a second mode, with the display controller modifying the operation of the set of element drivers in the second mode so that the presentation of an image in the second mode consumes less power in the presentation of the same image in the first mode. - View Dependent Claims (35, 36, 37)
