Display Panel Pixel Column Segmentation for Narrow Non-Display Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing demand for mobile electronic devices with larger display areas and smaller non-display areas, as advancements in mobile electronic apparatuses increase their functionality, but existing technologies struggle to efficiently optimize the layout and signal transmission in these devices.
Innovation Solution
A display panel design that includes a first area with arranged pixels and a second area with higher light transmittance, where the pixels are not arranged, allowing for a signal transmission area through which optical signals can pass, while reducing the non-display area by connecting data lines and scan lines in a way that minimizes the peripheral area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a traditional display panel layout is used, then signal transmission is maintained, but the non-display area is large and the display area is limited
Solution Approach 1:
The display panel is divided into multiple pixel columns (first, second, and third pixel columns) arranged in sequence. The second area acts as a separator that divides the pixel columns into groups, allowing independent data line connections to each group while maintaining overall display functionality. This segmentation enables efficient signal transmission with reduced non-display area.
Solution Approach 2:
Multiple pixel columns are merged into groups that share common data lines. The first data line connects to both the first pixels and third pixels, while the second data line connects to the second pixels. This merging reduces the number of separate data lines needed, thereby reducing the non-display area while maintaining display functionality.
2Reliability
If data lines are extended to connect all pixels, then signal transmission is improved, but the non-display area increases
Solution Approach 1:
The pixel columns are segmented into distinct groups (first pixel column with first and third pixels, second pixel column with second pixels) that can be independently connected to data lines. This segmentation allows data lines to serve multiple pixel columns without requiring continuous extension across the entire display, reducing the non-display area while maintaining reliable signal transmission.
Solution Approach 2:
The data lines are designed with multi-functionality to connect to multiple pixel columns. The first data line serves both the first pixels and third pixels, while the second data line serves the second pixels. This universal connection approach reduces the total length of data lines required, thereby reducing the non-display area while ensuring reliable signal transmission to all pixels.
3Illumination intensity
If the second area is made larger to allow optical signal transmission, then light transmittance is improved, but the display area is reduced
Solution Approach 1:
The second area is strategically positioned between specific pixel columns (first, second, and third pixel columns) rather than spanning the entire display. This localized approach allows optical signal transmission in specific regions where needed, while maintaining display functionality in other regions. The data lines are routed through the peripheral area, allowing the second area to be optimized for light transmittance without significantly reducing the overall display area.

Data Source
AI summary
A display panel includes a first area in which first pixels of a first pixel column, second pixels of a second pixel column, and third pixels of a third pixel column are arranged, a second area which cuts off each of the first pixel column, the second pixel column, and the third pixel column and through which an optical signal travels, and first to third data lines. The first data line is connected to the first pixels and a portion of the third pixels arranged on one side of the second area in a direction in which the pixel columns extend, the second data line is connected to the second pixels, and the third data line is connected to a remaining portion of the third pixels arranged on the other side of the second area in the direction in which the pixel columns extend.
