Display Panel Reset Signal Partitioning for Uniform Multi-Rate Refresh
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 states of drive transistors, adjusting the refresh rates and light emission durations to minimize display non-uniformity.

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 reset signals to different pixel circuits in different display regions. Each region receives reset signals customized to its specific refresh rate, allowing optimal performance for each local area while maintaining overall system efficiency. This resolves the contradiction by enabling low power consumption through partitioned refresh rates while preventing display non-uniformity through localized signal optimization.
2Productivity
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 applies parameter changes by dynamically adjusting reset signal parameters (such as signal strength, duration, or timing) according to the refresh rate of each display region. This allows the system to optimize the reset mechanism for each region's specific operational parameters, maintaining display uniformity while achieving the productivity benefits of differentiated 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 reset signal including a first reset signal and a second reset signal, where when a refresh rate of the first display region is f1, the first pixel circuit receives the first reset signal, and when a refresh rate of the second display region is f2, the second pixel circuit receives the second reset signal.
