Display Driving Controller White Balance Voltage Adjustment

The patent applies source emphasis selectively to specific pixels based on their white balance status and neighboring pixel states. Instead of uniformly increasing data voltage across all pixels, the controller identifies pixels with white balance outside the set range and applies enhanced voltage only to those pixels and their neighbors, thereby improving charging speed locally without causing widespread color coordinate shifts.

The patent dynamically adjusts the data voltage based on real-time analysis of white balance values and neighboring pixel states. The controller continuously monitors pixel conditions and modifies the charging voltage accordingly, transitioning from a static voltage approach to a dynamic, adaptive voltage adjustment that responds to changing display conditions.

The patent implements localized voltage enhancement by identifying specific pixels that require source emphasis based on white balance analysis. Only pixels with white balance outside the acceptable range and their neighboring pixels receive increased voltage, while other pixels maintain normal voltage levels. This selective approach improves overall charging efficiency without compromising display quality across the entire panel.

The patent changes the voltage parameter dynamically based on white balance conditions. When a pixel's white balance falls outside the set range, the controller increases the data voltage for that pixel and its neighbors; when white balance is within range, normal voltage is applied. This parameter adjustment strategy optimizes charging speed while maintaining color accuracy.
