Display Panel Bias Adjustment for Mixed Refresh Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display non-uniformity occurs in current display panels when partition refresh rates are different, affecting the display effect.
Innovation Solution
A display panel with at least two display regions and pixel circuits, where each region receives distinct bias adjustment signals to optimize the bias state of drive transistors, adjusting their working states to match the varying refresh rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If partition refresh rate control is implemented to reduce power consumption, then power consumption is reduced, but display non-uniformity occurs
Solution Approach 1:
The patent applies local quality by providing different bias adjustment signals to different display regions based on their specific refresh rates. Each display region receives a bias adjustment signal customized to its refresh rate condition, ensuring that the bias state of drive transistors is optimized for each region's operational parameters, thereby maintaining display uniformity across regions with different refresh rates while enabling power savings through partitioned refresh control
2Use of energy by stationary object
If different refresh rates are used in different display regions, then power consumption is reduced, but display non-uniformity occurs
Solution Approach 1:
The patent implements dynamics by making the bias adjustment signal adaptive to the refresh rate of each display region. The bias adjustment signal is dynamically configured based on the specific refresh rate conditions of different regions, allowing the system to adapt the transistor bias states to match the varying operational requirements of different display regions, thereby maintaining display consistency despite different refresh rates

AI summary
Provided are a display panel and a display device. The display panel includes at least two display regions and a pixel circuit. The at least two display regions include a first display region and a second display region. The pixel circuit includes at least a first pixel circuit and a second pixel circuit, where the first pixel circuit is disposed in the first display region and the second pixel circuit is disposed in the second display region. The pixel circuit receives a bias adjustment signal including a first bias adjustment signal and a second bias adjustment signal, where when a refresh rate of the first display region is f1, the first pixel circuit receives the first bias adjustment signal, and when a refresh rate of the second display region is f2, the second pixel circuit receives the second bias adjustment signal.
