Mobile Device Buffer Structure for Display Touch Panel Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile devices with rear-type touch panels, the placement of the touch panel over the display leads to a decrease in image quality and generates false signals due to pressure from display bending caused by gravity.
Innovation Solution
A buffer structure with a gas fluid layer and spacers is introduced between the display and the touch panel, preventing direct contact and thus preventing the transmission of pressure-induced false signals, with the gas fluid layer and spacers positioned between the display and the touch panel to maintain separation and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased, then the display area is improved, but the display bending due to gravity causes false signals
Solution Approach 1:
A buffer structure comprising a gas fluid layer and spacers is introduced as an intermediary between the display and touch panel. This buffer structure prevents direct contact while maintaining separation, thereby eliminating the transmission of pressure-induced false signals from display bending to the touch panel, while still allowing large display areas to be utilized.
2Device complexity
If the touch panel is placed over the display, then the device structure is simplified, but the image quality deteriorates
Solution Approach 1:
The patent inverts the conventional arrangement by placing the touch panel behind the display rather than over it. This rear-type configuration eliminates the interference of the touch panel with light transmission, thereby maintaining high image quality while still achieving a simplified overall device structure through the buffer structure implementation.
3Length of stationary object
If the display and touch panel are attached directly, then the device thickness is reduced, but pressure transmission causes false signals
Solution Approach 1:
The buffer structure with gas fluid layer and spacers serves as a thin intermediary between the display and touch panel. This intermediary maintains the necessary separation to prevent pressure transmission and false signal generation while minimizing the increase in device thickness, achieving a balance between reliability and compactness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively prevents false signals by ensuring the display and touch panel remain non-contact, enhancing image quality and reducing the need for transparent conductive materials.
Implementation Method 1
The buffer structure has a gas fluid layer and is disposed between the display and the touch panel
