Pixel Charging Time Modulation for Display Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel technologies fail to achieve uniform charging times across pixel units, leading to poor display quality due to internal delays and non-linear changes, resulting in better performance at the ends and poorer performance in the middle areas.
Innovation Solution
A method to modulate charging times by obtaining relational data between charging rates and times, calculating an average charging time, and adjusting initial charging times of pixel units to equal the average, ensuring uniformity across the display panel.

Engineering Contradiction Analysis
1Manufacturing precision
If linear charging time modulation is applied to middle pixel units, then near end and far end charging rates are balanced, but middle pixel unit charging rate deteriorates
Solution Approach 1:
The patent applies different charging time modulation strategies to different regions of the display panel. Specifically, it divides pixel units into near end, middle, and far end regions along the data signal transmission direction, and applies non-linear modulation to middle regions while using linear modulation for end regions. This local differentiation resolves the contradiction by optimizing each region's charging characteristics according to its specific needs.
Solution Approach 2:
The patent changes the charging time parameter non-linearly for middle pixel units based on their position and charging characteristics. By introducing a non-linear modulation function that adjusts charging time according to the pixel unit's distance from the data signal output and its specific charging rate characteristics, the system achieves uniform charging across all regions without compromising display quality.
2Manufacturing precision
If charging time is increased for far end pixel units, then charging completeness improves, but overall charging time and response speed increase
Solution Approach 1:
The patent applies extended charging time compensation specifically to far end pixel units that suffer from signal attenuation and charging incompleteness. By identifying which pixel units are located in far end regions and applying targeted non-linear modulation to extend their charging time, the system ensures charging completeness without requiring a blanket increase in charging time for the entire display panel, thus maintaining overall response speed.
Solution Approach 2:
The patent dynamically adjusts charging time based on real-time characteristics of different pixel units. The non-linear modulation function continuously adapts charging time parameters according to each pixel unit's position, charging rate, and completeness metrics, allowing the system to optimize between charging completeness and response speed for each individual region rather than using a static global parameter.

AI summary
A charging time modulating method is disclosed. After obtaining relational data between a charging rate and a charging time of pixel units on each pixel area, an average charging time corresponding to a preset charging rate is calculated based on each relational data. Then, an initial charging time of the pixel units on each of the pixel areas is obtained, and the initial charging time of the pixel units on each of the pixel areas is adjusted according to the average charging time, so that the initial charging time of the pixel units on each of the pixel areas is equal to the average charging time.
