Display Panel Multiplexer Wiring for Narrow Border
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of wiring in display apparatuses due to higher resolution requirements leads to difficulties in arranging wires and results in a wide border area, making it challenging to manage the wiring effectively in the chip bonding area.
Innovation Solution
The implementation of a display panel with a border area that includes a chip bonding area on one side, where multiple data pins and multiplexers are arranged, allowing for efficient electrical connections between data input wires and data pins through the active area, reducing the need for extensive wiring and facilitating a narrow border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If more data wires are arranged to support higher resolution, then display resolution is improved, but wiring complexity in the chip bonding area increases
Solution Approach 1:
Multiple data wires are merged into a single data input wire by using a multiplexer. The multiplexer combines several data signals that would otherwise require separate wires, allowing them to be transmitted through one shared wire to the chip bonding area, thereby reducing wiring complexity while maintaining support for high resolution displays
Solution Approach 2:
The data input wire serves multiple functions by being shared among multiple data channels through the multiplexer. A single wire performs the function of transmitting multiple data signals at different time slots, making the wiring system more universal and reducing the total number of wires needed in the chip bonding area
2Measurement precision
If more data wires are arranged in the chip bonding area, then display resolution is improved, but the border area width increases
Solution Approach 1:
Multiple data wires are merged into one shared data input wire using a multiplexer in the border area. This consolidation reduces the number of individual wire connections needed in the chip bonding area, allowing the border area to be narrowed while still supporting high resolution displays through the multiplexed data transmission
3Measurement precision
If more data wires are arranged to support higher resolution, then display resolution is improved, but wire arrangement difficulty increases
Solution Approach 1:
Multiple data wires are merged into a single data input wire through the multiplexer, significantly reducing the number of wire connections that need to be manually arranged and connected in the chip bonding area. This merging simplifies the manufacturing process and makes wire arrangement much easier while still supporting high resolution displays
Solution Approach 2:
The data input wire becomes a universal connection that serves multiple data channels through time-division multiplexing. This universal approach reduces the number of specialized wire connections needed, simplifying the overall wire arrangement process and making manufacturing easier

AI summary
A display panel and a display apparatus are provided according to the present disclosure. First multiplexers are arranged on a second side of an active area. Less wiring is arranged in a chip bonding area in a border area, and therefore wires can be easily arranged in the chip bonding area in the border area, facilitating a narrow border of the display apparatus.
