Solution Overview

Problem

Current OLED displays face issues with low pixel detection speed due to the need to detect and compensate pixels row by row, leading to short display time and affected normal display performance.

Innovation Solution

A display panel and driving method where each first sub-pixel group corresponds to two compensation detection lines, allowing two sub-pixels from adjacent rows to be detected together, with sub-pixels in every three columns forming a group and being coupled with different detection lines, thereby increasing detection speed and extending display time.

VSEngineering Contradiction Analysis

1Speed

If pixels are detected and compensated row by row, then detection can be performed systematically, but detection speed is low and display time is short

Engineering Contradiction:
Improvedetection speedVSAvoiddisplay time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent merges the detection of multiple sub-pixels by coupling them to the same compensation detection line. Specifically, sub-pixels in different columns (first column to first detection line, third column to second detection line, second column to both lines) are combined into groups that share detection resources, allowing parallel detection and significantly improving detection speed while extending display time

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the array of sub-pixels into groups of three columns, where each group is associated with two compensation detection lines. This segmentation allows for organized parallel processing of detection signals while maintaining systematic compensation across the entire display panel

Inventive Principle:
Principle #1Segmentation
