Staggered Display Panel Sub-Pixels Reduce Parasitic Capacitance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face limitations in reducing sub-pixel size for high-resolution displays, leading to light halo phenomena and color deviation when displaying circular zone plate patterns, which deteriorate the display effect.
Innovation Solution
A display panel design with sub-pixels arranged in a staggered pattern on intersecting directions, featuring obliquely disposed data segments that reduce parasitic capacitance without compromising aperture ratio, thereby improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sub-pixel size is reduced to achieve high resolution, then display resolution is improved, but light halo phenomenon and color deviation occur deteriorating display quality
Solution Approach 1:
The patent applies asymmetry by implementing a staggered arrangement where sub-pixels in adjacent rows are shifted relative to each other by a predetermined distance. This breaks the symmetric grid pattern that causes light halo and color deviation, while still achieving high resolution through the staggered configuration
2Ease of manufacture
If data line and scanning line are arranged orthogonally, then routing is simplified, but parasitic capacitance increases affecting display performance
Solution Approach 1:
The patent transitions from a two-dimensional orthogonal routing to a three-dimensional configuration by introducing oblique segments. The second data segments extend in a third direction at an angle between 0 and 90 degrees relative to the scanning line, reducing overlap area and thus parasitic capacitance while maintaining electrical connectivity

AI summary
A display panel includes a plurality of sub-pixels, scanning lines and data lines. The sub-pixels are disposed on a first substrate and include a plurality of rows and columns, and each sub-pixel of a first row of two adjoining rows is shifted by a predetermined distance along a first direction with respect to each sub-pixel of a second row of two adjoining rows. The scanning lines extend in the first direction and corresponding to the sub-pixels of the rows respectively. Each data line includes a plurality of first data segments and second data segments connected alternately. The first data segment extends along a second direction and partially overlaps the scanning line in a vertical direction. Each second data segment is disposed on one side of the scanning line, and at least a portion of the second data segments extends along a third direction different from the first and second directions.
