Display Panel Data-Line Multi-Angle Shape for Color Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display panels with four sub-pixels arranged in a row, the mixed color of light beams from the two outer sub-pixels is not effectively rendered due to spacing issues, leading to color line defects, especially when sub-pixels are vertically aligned.
Innovation Solution
The display panel configuration includes a data-line with a multi angle-shaped portion having an inclined line and a straight-shaped portion extending in the first direction, which allows the light-emitting regions of adjacent sub-pixels to protrude symmetrically, reducing the space between outer sub-pixels and enhancing color mixing, while maintaining symmetrical arrangements of inner sub-pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If four sub-pixels are arranged in a row with two inner sub-pixels between the two outer sub-pixels, then each unit pixel can include four different colors (red, green, blue, white), but the space between the two outer sub-pixels becomes too large for effective color mixing
Solution Approach 1:
The data line is designed with a multi-angle shape including inclined portions that extend in both horizontal and vertical directions. This dimensional change allows the data line to reach adjacent light-emitting regions of outer sub-pixels without requiring a large horizontal space, thereby enabling effective color mixing while maintaining four different colors in each unit pixel.
Solution Approach 2:
The data line incorporates inclined portions with angled configurations rather than straight horizontal lines. These curved/angled paths allow the data line to connect distant light-emitting regions more efficiently, reducing the effective horizontal spacing between outer sub-pixels and enabling better color mixing.
2Manufacturing precision
If sub-pixels are arranged vertically, then the display panel can achieve high resolution, but color line defects occur where colors are individually rendered as vertical lines instead of mixed colors
Solution Approach 1:
The data line acts as an intermediary element that physically connects adjacent light-emitting regions of outer sub-pixels through its multi-angle configuration. This intermediary structure enables optical interaction and color mixing between sub-pixels that would otherwise be too far apart, preventing the formation of color line defects while maintaining vertical arrangement for high resolution.
3Device complexity
If the data line is arranged in a straight vertical configuration, then the circuit layout is simple, but it cannot effectively connect adjacent light-emitting regions for color mixing
Solution Approach 1:
The data line is segmented into multiple portions with different orientations: vertical portions for connecting to circuit elements and inclined portions for reaching adjacent light-emitting regions. This segmentation allows the data line to perform multiple functions - maintaining circuit simplicity while effectively connecting distant regions for color mixing.

Function Achieved in This Case
This configuration effectively suppresses color line defects by minimizing the space between light-emitting regions of outer sub-pixels, improving color mixing and rendering of mixed colors.

AI summary
The present disclosure provides a display panel. The display panel includes the plurality of unit pixels arranged in a matrix within the display region, wherein each unit pixel includes first, second, third and fourth sub-pixels which are sequentially arranged in a row in a first direction and correspond to different colors. The data-line corresponds to a vertical line including sub-pixels arranged in a line in the second direction orthogonal to the first direction. The data-line includes: a straight-shaped portion disposed along and between adjacent non-light emitting regions and extending in the second direction; and a multi angle-shaped portion disposed along and between adjacent light-emitting regions, wherein the multi angle-shaped portion includes: an inclined line inclined relative to the second direction; and a straight-shaped portion extending in the first direction. Thus, a minimum space between the light-emitting regions of the outer first and fourth sub-pixels defining the outer sub-pixels of the unit pixel may be smaller than a space between the non-light emitting regions thereof. Therefore, color mixing between the light beams as emitted from the outer first and fourth sub-pixels may be easily rendered.
