Display Panel Opening Layout for Emission Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges in efficiently integrating components like cameras and sensors while maintaining optimal display functionality, particularly in terms of signal transmission and emission control around opening areas.
Innovation Solution
The display panel design includes a substrate with an opening area surrounded by a display area, non-display areas, and specific arrangements of data lines, scan lines, and emission control lines that detour around the opening area, with emission control and scan drivers positioned in non-display areas to provide signals to connected lines, ensuring efficient signal transmission and minimizing the number of drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emission control lines are arranged on both sides of the opening area, then signal transmission efficiency is improved, but the number of emission control drivers increases
Solution Approach 1:
The patent merges the functions of multiple emission control drivers by connecting emission control lines from both sides of the opening area to a single emission control driver. This is achieved by arranging first emission control lines on a first side of the opening area and second emission control lines on a second side, with both sets of lines connected to the same driver, thereby reducing the total number of drivers while maintaining efficient signal transmission to all emission control lines.
Solution Approach 2:
The patent utilizes the spatial dimension around the opening area by arranging emission control lines on both the first side and second side of the opening area. This two-sided arrangement allows signals to be distributed more efficiently across the display panel while still being controlled by a single driver through proper routing and connection of the emission control lines.
2Adaptability or versatility
If data lines detour around the opening area, then component integration is enabled, but signal transmission path length increases
Solution Approach 1:
The patent segments the data lines into multiple sections that detour around the opening area. Instead of a single long path, the data lines are divided into segments that navigate around the opening area in an organized manner, allowing components to be integrated in the opening area while managing the signal transmission path length through systematic routing.
Solution Approach 2:
The patent employs curved detour paths for data lines around the opening area rather than sharp angular turns. This curved routing approach allows the data lines to gracefully navigate around the opening area, enabling component integration while minimizing unnecessary path length and maintaining signal transmission efficiency.

AI summary
A display panel may include the following elements: a substrate including an opening area, a display area surrounding the opening area, and a first non-display area between the opening area and the display area; a data line positioned at a first side relative to the opening area; a first scan line; a second scan line; a first pixel connected to the data line and the first scan line; a second pixel connected to the data line and the second scan line; a first emission control line connected to the first pixel; a connecting section positioned on the first non-display area; a second emission control line connected to the second pixel and connected through the connecting section to the first emission control line; and an emission control driver configured to simultaneously provide emission control signals to the first emission control line and the second emission control line.
