Abstract

Drive signals for a display device may be generated using Separable Nonnegative Matrix Series Representation (SNMSR) of source image data and applying a non-negative matrix factorization (NNMF) process to source image data to generate approximation image data (Ii), partial sum image data (Pi) and residue image data (Ji). Iteratively, NNMF may be applied to Ji such that subsequent Ii and Ji may be generated, where each Ii can be associated with a corresponding sub-frame image. At each iteration, the Ii may be sent to the display buffer for selective activation of multiple row and column drivers during a single sub-frame interval. At each iteration, a determination may be made if a predetermined criterion is satisfied. The iterations may be terminated and the series truncated when the predetermined criterion is satisfied. Integration of the sub-frame images displayed over a complete frame interval by human eye effectively corresponds to the source image.

Description

[0001] Cross references to related applications [0002] This application claims the priority of the corresponding patent application with application number 3119 / DEL / 2010 filed in India on December 28, 2010, the entire content of which is incorporated herein by reference. Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application, and the inclusion of these materials in this section is not an admission that these materials are prior art. [0004] Organic light emitting diode (OLED) devices (also called organic electroluminescence (EL) devices) can provide a number of advantages over other flat panel display devices of earlier technology types. High emission brightness, relatively wide viewing angles, reduced device thickness, and reduced electrical power consumption are example characteristics that can be considered as potential advantages of OLED devices compared to, for example, liqui...
