Sensing Frame for Non-Touch Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display units without touch panels cannot provide touch control functions, limiting user interaction to non-touch input methods like keyboards and mice.
Innovation Solution
A frame with a sensing function is hanged on a display unit, equipped with a sensor and processing unit that calculates and provides position transformation parameters to enable touch control by sensing touched positions and transforming them into corresponding operations on the display content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display unit is equipped with a touch panel, then touch control function is provided, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent introduces a frame as an intermediary component that houses the sensing function. The frame acts as a mediator between the display unit and the touch control capability, allowing non-touch display units to gain touch functionality without integrating a touch panel directly into the display structure. The frame includes a sensing element that detects touch positions and transmits this information to the processing unit, enabling touch control through an external additive component rather than internal integration.
Solution Approach 2:
The touch control function is segmented into separate modular components: the frame with sensing element, the processing unit, and the display unit. This segmentation allows the touch control capability to be added independently without redesigning the entire display system. The frame can be hung on or attached to existing display units, providing touch functionality as a separate module that can be configured and controlled independently.
2Measurement precision
If position transformation calculation is performed in the processing unit, then accurate touch control is achieved, but use of energy and computational resources increase
Solution Approach 1:
The system performs position transformation calculation only when necessary - specifically when the frame's position relative to the display unit changes or during initial setup. Once the transformation parameters are established, the system uses these pre-calculated values for subsequent touch operations without requiring continuous complex computations. This partial action approach maintains measurement precision while significantly reducing ongoing computational energy consumption.

AI summary
A frame with a sensing function includes a frame structure, a sensor and a processing unit. The processing unit is electrically connected to the sensor. The frame structure is configured for hanging on a display unit. The sensor senses a touched position set of the display unit for position setting. The processing unit includes a parameter calculating module and a parameter providing module. The parameter calculating module calculates a position transformation parameter between the hanged frame structure and the display unit according to the touched position set. The parameter providing module provides the position transformation parameter, such that a display content displayed on the display unit is controlled according to at least one touched position for operation sensed by the sensor and the position transformation parameter.
