Solution Overview
Problem
Existing electronic apparatuses face challenges in providing uniform sensitivity to external inputs across their entire active area, particularly due to the presence of openings that disrupt the sensing electrodes.
Innovation Solution
The electronic apparatus incorporates an electronic panel with multiple sensing groups arranged in a grid pattern, featuring sensing lines that connect these groups. Each sensing group includes a first sensing electrode and multiple second sensing electrodes, with the opening pattern extending along the edge of the opening to receive the same electrical signal as the main pattern, ensuring continuous signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening is provided in the electronic panel to accommodate an electronic module, then the electronic module can be integrated into the device, but the sensing electrode area is reduced and sensitivity becomes non-uniform
Solution Approach 1:
The sensing electrode is divided into a main pattern and an opening pattern. The main pattern is positioned away from the opening while the opening pattern is specifically positioned to extend along the edge of the opening, allowing each segment to serve its specific sensing function and compensate for the area loss caused by the opening.
Solution Approach 2:
The opening pattern is designed with different characteristics from the main pattern - it extends along the edge of the opening and has a different shape configured to receive substantially the same electrical signal. This local modification compensates for the reduced sensing area near the opening while maintaining overall sensitivity uniformity.
2Volume of stationary object
If the sensing electrode area is reduced due to the opening, then the electronic module can be accommodated, but the sensitivity to external inputs decreases
Solution Approach 1:
The opening, which initially causes harm by reducing the sensing electrode area, is converted into a benefit through the opening pattern. The opening pattern is specifically designed to extend along the edge of the opening and receive the same electrical signal, transforming the problematic area into an effective sensing region that compensates for the lost area.
3Manufacturing precision
If the sensing electrode pattern is modified to extend along the opening edge, then sensitivity uniformity is improved, but the device complexity increases
Solution Approach 1:
The opening pattern is electrically connected to the main pattern, merging them into a unified sensing electrode structure. This connection allows the opening pattern to receive the same electrical signal as the main pattern, integrating the modified region into the overall sensing system without requiring separate signal paths or additional complexity.

AI summary
An electronic apparatus includes an electronic panel including a plurality of sensing groups spaced apart from each other, and an electronic module overlapping with the electronic panel in a plan view. Each of the sensing groups includes a first sensing electrode extending in a second direction, and second sensing electrodes spaced apart from each other in the second direction, located on the same layer as the first sensing electrode, and face the first sensing electrode in a first direction. An opening overlapping with the electronic module and penetrating a first sensing group of the sensing groups is defined in the electronic panel, and at least one selected from the first sensing electrode and the second sensing electrodes of the first sensing group extends along an edge of the opening.
