Abstract
Improvement for extending the service life of a self-emitting panel and for reducing the power consumption thereof. The self-emitting panel is driven based on intensity-reduced data. The intensity-reduced data is obtained by applying intensity reduction processing on each frame of the image frame data to be displayed.
Claims28
A method of creating drive data for a respective frame of image frame data according to a data signal containing the image frame data, and driving a self-emitting panel based on the created drive data to display a two-dimensional image, the self-emitting panel having two crossing electrode groups such that intersecting points of the two electrode groups serve as light emitting points, the method comprising:
- an intensity reduction step of performing intensity reduction processing for said image frame data to lower picture element intensity of at least one frame of the image frame data;
- and
- a creation step of creating said drive data based on the image frame data after the reduction of the intensity.
A method according to any one of the preceding claims, wherein the intensity reduction rate is selected so as not to deteriorate a contour of an image frame resulting from the frame of said image frame data.
An apparatus for driving a self-emitting panel based on a data signal containing image frame data to display a two-dimensional image, the self-emitting panel having two crossing electrode groups such that intersecting points of the two electrode groups serve as light emitting points, the apparatus comprising:
- image frame creation means for extracting said image frame data from said data signal;
- intensity reduction means for adjusting a value of said image frame data to reduce intensity of a respective frame of said image frame data;
- creation means for creating said drive data based on the image frame data of which intensity has been reduced;
- and
- a driver for driving said self-emitting panel based on said drive data.
