Display Panel Multiplexer Layout for Narrow Lower Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reducing the width of the lower frame region in display panels is challenging due to the presence of complex circuits and signal lines, making it difficult to achieve a narrow bezel or bezel-less design.
Innovation Solution
The display panel design incorporates a non-display region with multiplexers and connection lines arranged in a specific configuration, including a first non-display sub-region with multiplexers and connection lines that connect to the display region, reducing the layout difficulty and short-circuiting risk, and allowing for a smaller screen-to-body ratio.

1Area of moving object
If the lower frame region width is reduced to achieve narrow bezel display, then the screen-to-body ratio is improved, but the layout complexity and short-circuiting risk of connection lines increase due to complex circuits and signal lines
Solution Approach 1:
The display panel is divided into a display region and a non-display region, with the non-display region further divided into a first non-display sub-region and a second non-display sub-region. The multiplexers are arranged in the first non-display sub-region while connection lines are arranged in the second non-display sub-region, separating different functional elements to reduce layout complexity and short-circuiting risk.
Solution Approach 2:
The patent utilizes the vertical dimension by arranging multiplexers and connection lines in different non-display sub-regions (first and second sub-regions) rather than horizontally in the same region. This vertical separation allows for reduced horizontal frame region width while maintaining functional integrity and reducing layout complexity.
2Length of stationary object
If multiple multiplexers and connection lines are arranged in a compact non-display region, then the frame region width is reduced, but the risk of short-circuiting between connection lines increases
Solution Approach 1:
The non-display region is segmented into a first non-display sub-region for multiplexers and a second non-display sub-region for connection lines. This spatial segmentation physically separates elements that could potentially short-circuit, reducing the risk while maintaining compact overall dimensions.
Solution Approach 2:
The patent introduces a second non-display sub-region as an intermediary space between the multiplexers (in the first non-display sub-region) and the display region. This intermediary region houses the connection lines, acting as a buffer zone that prevents direct contact between potentially conflicting electrical elements, thereby reducing short-circuiting risk.

AI summary
A display panel includes a non-display region and a display region. A first non-display sub-region of the non-display region includes multiplexers and first connection lines, and the multiplexer is electrically connected to a first end of the first connection line. A display region includes a first display sub-region and a second display sub-region. The first display sub-region and the first non-display sub-region are arranged along a second direction crossing the first direction. The display region includes first signal lines arranged along the first direction and second connection lines. The first connection lines include a first connection sub-line and a second connection sub-line. The first signal line in the first display sub-region is electrically connected to a second end of the first connection sub-line, and the first signal line in the second display sub-region is electrically connected to a second end of the second connection sub-line through the second connection line.
