Display Panel Data-Line Routing for Narrow Camera Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in full-screen technology is the need to accommodate a camera opening in the display area, which often results in larger openings, signal line congestion, and visible black edges, affecting the appearance and display effect.
Innovation Solution
A display panel design with first and second data lines on either side of the opening area, using data selectors and connection leads to bypass the opening, allowing data signals to be provided through data selection data lines and connection leads, reducing the need for additional input terminals and minimizing the peripheral area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening is arranged in the display area to accommodate the under-screen camera, then the camera can be integrated into the full-screen display, but the opening diameter increases and black edges appear, affecting the appearance and display effect
Solution Approach 1:
The data lines are segmented into first data lines and second data lines, with the first data lines passing through the opening area and the second data lines arranged outside the opening area. This segmentation allows the display to maintain a smaller opening diameter while still accommodating the camera, as the pixel circuits can receive data signals through either path.
Solution Approach 2:
The patent introduces a new dimension by adding a second direction (Y-direction) for data line arrangement, in addition to the traditional first direction (X-direction). This allows data lines to be distributed in multiple directions, enabling the opening to be positioned without creating large black edges, as signals can reach pixels through both X and Y direction pathways.
2Reliability
If many signal lines are arranged to bypass the opening area, then all pixels can be connected to data lines, but the number of input terminals and peripheral area increases
Solution Approach 1:
The pixel circuits are designed with universal functionality to accept data signals from multiple sources: they can receive data from first data lines passing through the opening area or from second data lines arranged outside the opening area. This multi-functionality reduces the need for separate input terminals for different signal paths, thereby reducing peripheral area and device complexity.
Solution Approach 2:
The patent merges the function of multiple data line paths into a unified pixel circuit architecture. Both the first data lines (through the opening) and the second data lines (outside the opening) converge to the same pixel circuits, eliminating the need for separate terminal structures and reducing the overall peripheral area required.

AI summary
A display panel includes a display area, a peripheral area and an opening area. The display panel includes: first data lines including first sub-data lines and second sub-data lines; data selectors including first data selectors and second data selectors, where the first data selectors are electrically connected with the first sub-data lines, and the second data selectors are electrically connected with the second sub-data lines; a plurality of data signal input terminals; a plurality of first data selection data lines including first sub-data selection data lines and second sub-data selection data lines, where the first sub-data selection data lines are electrically connected with the first data selectors, and the second sub-data selection data lines are electrically connected with the second data selectors and the data signal input terminal; and a plurality of first connection leads located outside the opening area and extending from the display area to the peripheral area.
