SYSTEMS AND METHODS OF REDUCED MEMORY BANDWIDTH COMPENSATION
First Claim
Patent Images
1. A method for compensating an image produced by an emissive display system having pixels, each pixel having a light-emitting device, the method comprising:
- measuring characteristics of a plurality of pixels generating measurement data for use in compensation of the display;
storing the measurement data in a memory;
retrieving partial resolution measurement data from the measurement data stored in the memory;
interpolating the measurement data generating full resolution interpolated measurement data; and
compensating the display with use of the full resolution interpolated measurement data.

Abstract
What is disclosed are systems and methods of compensation of images produced by active matrix light emitting diode device (AMOLED) and other emissive displays. Sub-sampling of pixel measurement data utilized in compensation of the display is utilized to reduce the data bandwidth between memory and a compensation module where the data is locally interpolated.

11. A system for compensating an image produced by an emissive display system having pixels, each pixel having a light-emitting device, the system comprising:
-
a display comprising said pixels; a monitoring system coupled to said pixels of said display and for measuring characteristics of a plurality of said pixels generating measurement data for use in compensation of the display; a memory for storing the measurement data; an interpolation module for retrieving partial resolution measurement data from the measurement data stored in the memory and interpolating the measurement data generating full resolution interpolated measurement data; and a compensation module for compensating the display with use of the full resolution interpolated measurement data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
