Display Panel Compensation Lines for Uniform Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Specially-shaped display panels experience uneven displaying due to inconsistent loading of signal lines with different lengths, leading to poor user experience, especially in large-sized devices, as existing compensation methods either fail to address resistance differences or result in increased border widths.
Innovation Solution
A display panel design with compensation lines that are electrically connected to signal lines to compensate for size differences, using fewer compensation lines than signal lines, ensuring uniform loading and reducing border width without occupying display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal lines of different lengths are used in specially-shaped display panels, then the display panel can adapt to overall structure and use requirements, but the loading of signal lines becomes inconsistent causing uneven displaying
Solution Approach 1:
The patent applies local quality by making different parts of the signal lines have different properties. Specifically, compensation lines are added only to signal lines that require compensation (those with different lengths), while reference lines remain unchanged. This localized modification allows the display panel to maintain adapting to specially-shaped structures while ensuring uniform loading characteristics for displaying consistency.
2Manufacturing precision
If compensation lines are added to signal lines to compensate for size differences, then displaying uniformity can be improved, but the border width increases
Solution Approach 1:
The patent resolves the border width issue by transitioning to another dimension - placing compensation lines in the vertical direction (along the extension direction of signal lines) rather than expanding horizontally at the border. This dimensional change allows compensation to occur within the existing border area, achieving displaying uniformity without increasing border width.
3Manufacturing precision
If compensation lines are electrically connected to signal lines, then loading differences can be compensated, but the number of compensation lines increases complexity
Solution Approach 1:
The patent applies universality by designing compensation lines that can serve multiple functions. The same compensation line structure can be applied to different signal lines (gate-signal lines and data-signal lines) regardless of their specific length variations. This standardized approach reduces overall complexity by using a universal compensation mechanism rather than custom solutions for each signal line.

AI summary
The application provides a display panel. The display panel includes a display area, and the display area includes: a plurality of kinds of signal lines, wherein a same kind of signal lines include reference lines and lines to be compensated, sizes of the lines to be compensated along extension directions of the lines to be compensated are smaller than sizes of the reference lines along extension directions of the reference lines; and compensation lines, including first compensation lines, wherein the first compensation lines are electrically connected with the lines to be compensated, for compensating differences between the sizes of the lines to be compensated along the extension directions of the lines to be compensated and the sizes of the reference lines along the extension directions of the reference lines, wherein a number of the compensation lines is less than or equal to a number of the signal lines.
