Touch Screen Cover Transparent Area Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens covered with protective cases are inconvenient as users cannot directly see the frame, and existing methods fail to detect transparent areas accurately, leading to incomplete or incorrect frame display.
Innovation Solution
The method involves using touch screens with transparent areas made of conductive materials and non-transparent areas made of non-conductive materials, allowing the screen to detect energy variations to determine the cover range and adjust the displayed frame accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is used to protect the touch screen, then the touch screen is protected from scratches, but the user cannot directly see the frame of the touch screen
Solution Approach 1:
The protective cover is designed with transparent areas at specific locations corresponding to the touch screen frame, while other areas remain opaque for protection. This local differentiation allows the frame to be visible through the transparent regions while maintaining overall screen protection.
2Ease of operation
If holes or transparent areas are formed in the protective cover to allow frame visibility, then the frame becomes visible, but the electronic device cannot detect the positions of these transparent areas
Solution Approach 1:
The touch screen detects touch inputs through the protective cover and provides feedback by determining the positions of transparent areas based on detected energy variations. This feedback mechanism allows the system to automatically identify and adapt to the cover's transparent area configuration.
3Loss of information
If the electronic device displays the full frame, then the complete frame is displayed, but power consumption increases and user convenience decreases
Solution Approach 1:
The system extracts and displays only the portions of the frame that correspond to transparent areas of the protective cover, rather than displaying the complete frame. This selective display reduces power consumption while maintaining the visibility of relevant frame elements through the transparent cover areas.
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 approach enables accurate detection of transparent areas on protective covers, allowing for adjustable frame display without user intervention, enhancing user convenience and reducing power consumption.
Implementation Method 1
the at least one transparent area and other areas of the cover have different conductivities
Data Source
AI summary
A method and an electronic apparatus for adjusting display frames by detecting touch of a cover are provided. The electronic apparatus includes a touch screen and a cover, and the cover has at least one transparent area. In the method, a touch of the cover is detected by using the touch screen. At least one cover range of the at least one transparent area of the cover on the touch screen is determined according to a detected energy variation, in which the at least one transparent area and other areas of the cover have different conductivities. The frames displayed by the touch screen are adjusted in response to the at least one cover range of the at least one transparent area on the touch screen.
