Display Panel Sub-Pixel Electrode Segmentation for Dark Stripe Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution and high-refresh-rate liquid crystal display panels face issues with dark stripes due to increased data lines occupying excessive width, leading to reduced light-emitting areas.
Innovation Solution
The display panel design includes sub-pixel electrodes with multiple sections and data line groups, where sub-data line groups are arranged on both sides of the electrodes, connected to different rows and columns, reducing the width of data line groups and minimizing shading areas.

Engineering Contradiction Analysis
1Productivity
If the number of data lines is increased several times to achieve high refresh rate and high resolution, then the charging efficiency of liquid crystal display panel is improved, but the total width of data lines occupies more area between adjacent sub-pixel electrodes, causing dark stripes on the display panel
Solution Approach 1:
The patent divides the data line structure into multiple segments: data lines are grouped into data line groups, which are further divided into sub-data line groups. Each sub-pixel electrode is also divided into multiple sub-pixel electrode sections. This segmentation allows the data lines to be distributed more efficiently, reducing the concentrated width occupation and minimizing dark stripe effects while maintaining the necessary charging capacity for high refresh rates.
2Productivity
If the number of data lines is increased several times to charge multiple rows of sub-pixel electrodes simultaneously, then the voltage charging efficiency is improved, but the area blocked by data lines increases, reducing the light-emitting area
Solution Approach 1:
The patent optimizes the spatial arrangement of data lines by organizing them into groups and sub-groups that extend in different directions and positions relative to sub-pixel electrode sections. This multi-dimensional arrangement distributes the data line width occupation more evenly across the display panel, reducing localized blocking and maintaining light-emitting area while preserving simultaneous charging capability for multiple rows.

AI summary
A display panel and a display device are provided. The display panel comprises sub-pixel electrodes and data line groups. The data line group includes at least two sub-data line groups. The sub-pixel electrode includes at least two sub-pixel electrode sections. By dispersing the data lines in the data line group into each sub-data line group and arranging the plurality of the sub-data line groups on two sides of the sub-pixel electrode sections in each of the columns, the shading area of each of the data line groups can be reduced, thereby improving the problem of dark stripes on the display panel.
