Abstract

Disclosed is a system and method of an adaptive driving compensation for enhancing display uniformity. Multiple input data patterns of the display panel are compared with image data by an image analyzing means or a user and thereby generate display control commands if non-uniformity in the display of image is detected by the image analyzing means or the user. A difference between pixel data associated with a current line and a preceding line is compared with a predefined threshold. A look up table (LUT) is scanned to add a compensation value on the pixel data the current line based upon the display control commands if the difference between the pixel data of the current line and the preceding line is greater than the predefined threshold or otherwise retain the original value of the said pixel data. The input data patterns with compensated pixel data or original pixel data is displayed.

Description

technical field [0001] The applications described herein relate generally to electronic device display panels. In particular, the present application relates to adaptive drive compensation systems and methods for enhancing display uniformity. Background technique [0002] In recent years, technologically advanced display panels have been developed to cater to numerous customer-centric applications. With the vigorous development of display panel technology, the market and customers require high-performance display panels. A display panel with high resolution, high brightness and low power consumption is most preferable. However, it was observed that brightness non-uniformity has become a critical quality issue to be solved in design, especially when the panel loading increases. The characteristics of Vcom (common voltage, common voltage) / source (source) / gate (gate) are different between touch and display of the display panel. Left or right Vcom path resistance is not the ...
