Display Panel Driving with Interlaced Scanning for Pixel Charging

The patent segments the sub-pixels into multiple groups that are scanned and driven in alternating frames. Instead of scanning all sub-pixels continuously, only certain groups are activated in each frame, allowing other groups to charge without being scanned. This segmentation resolves the contradiction by dividing the pixel array into independent scan groups, enabling high refresh rate display while providing sufficient charging time for non-scanned pixels.

The patent implements periodic scanning where different sub-pixel groups are activated in alternating frames. First sub-pixel groups are scanned in odd frames while second groups charge, then roles reverse in even frames. This periodic action allows the display to maintain high refresh rate while ensuring each pixel group receives adequate charging time during its non-scanned periods.

The patent divides sub-pixels into multiple scan groups and alternates which groups are actively scanned and driven in different frames. Only the currently scanned groups consume significant power, while other groups remain in low-power charging mode. This segmentation reduces overall power consumption while maintaining complete display coverage across alternating frames.

Instead of driving all sub-pixels continuously, the patent applies partial action by only driving the subset of sub-pixels that are currently being scanned. The non-scanned sub-pixel groups are held in charging mode without full driving signals, reducing power consumption while ensuring they will be fully driven in subsequent frames when their group becomes active.

The patent segments adjacent sub-pixels into different scan groups separated by at least one unscanned row. This segmentation ensures that adjacent scanned rows are not directly consecutive, allowing intermediate charging periods that equalize gray scale levels and prevent the large gray scale differences that cause defective images like purple spots.

The patent implements beforehand cushioning by inserting unscanned rows between scanned rows. These unscanned rows act as cushioning elements that provide charging time for the scanned rows above and below them, preventing excessive gray scale differences before they occur. This proactive approach prevents defective images by ensuring gray scale uniformity is maintained through the cushioning effect of alternating scan patterns.
