Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure-sensitive modules in electronic devices are stacked perpendicular to the screen, leading to increased thickness and impacting user experience.
Innovation Solution
A display module is designed with a deformable member connected through a via to a metal conducting layer, allowing pressure-sensitive functionality integrated under the display screen, reducing overall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressure-sensitive module is stacked perpendicular to the screen, then the pressure sensing function is achieved, but the device thickness increases
Solution Approach 1:
The pressure-sensitive module is repositioned from a perpendicular stacking arrangement to a planar integration beneath the display screen. The pressure-sensitive electrode is disposed in the display area of the display device, changing the spatial dimension from vertical stacking to horizontal integration, thereby reducing device thickness while maintaining pressure sensing functionality
Solution Approach 2:
The pressure-sensitive module is merged with the display screen structure. The pressure-sensitive electrode is integrated into the display area, combining the display function and pressure sensing function into a unified structure, eliminating the need for separate stacked modules and reducing overall device thickness

AI summary
This application belongs to the technical field of electronic devices, and discloses a display module and an electronic device. The display module includes a display screen, a metal conducting layer, and an insulation protection layer that are superposed sequentially. The insulation protection layer includes at least one via. A side, of the insulation protection layer, facing away from the metal conducting layer is disposed with at least one deformable member, and the deformable member is electrically connected to the metal conducting layer through the via. When pressure is put on the display screen, the deformable member is deformed and outputs an electrical signal to the metal conducting layer.
