Display Driving Method Position-Based Charging Duration Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display panels increase in size, resolution, and refresh rate, the inconsistent circuit loads at different positions lead to inconsistent potential states among display points, affecting the display effect due to the constant output time of display control signals.
Innovation Solution
A display driving method that determines the first charging duration of each display point based on its position and generates a display control signal, adjusting the second charging duration to ensure consistency, by using a time duration determination module, signal generation module, and control start module to dynamically adjust the charging times.

Engineering Contradiction Analysis
1Manufacturing precision
If the display panel increases in size, resolution, and refresh rate, then the display quality and performance are improved, but the effective interval of the display control signal becomes shorter and the potential states of display points become inconsistent
Solution Approach 1:
The patent applies dynamics by making the charging duration adjustable and position-dependent. Instead of using a fixed charging duration for all display points, the system dynamically adjusts the charging duration based on the distance between each display point and the driver chip, allowing each pixel to be optimized for its specific electrical characteristics while maintaining consistent display performance across the entire panel
Solution Approach 2:
The patent implements local quality by applying different charging durations to different display points based on their positions. Display points closer to the driver chip receive different charging parameters than those farther away, compensating for variations in circuit load and ensuring uniform potential states across the display panel despite position-dependent electrical characteristics

Solution Approach 2:
The patent applies parameter changes by modifying the charging duration parameter based on the spatial position of display points. By changing this temporal parameter according to position, the system compensates for electrical inconsistencies caused by varying circuit loads, maintaining stable and consistent potential states across all display points
