Touch Display System for Medical Picture-in-Picture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical and monitor display systems require convenient operation of picture-in-picture functions and signal source switching, which is currently cumbersome and risky due to the need for manual button operation or remote control use, especially with protective plates on LCD screens.
Innovation Solution
A display processing system that includes a touch operation device and an electronic device with a processor, allowing users to perform touch operations to recognize gestures and generate control instructions for switching picture-in-picture positions and signal sources, enhancing user convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button operation or remote control is used to operate picture-in-picture functions and signal source switching, then the display system can be controlled, but the operation becomes cumbersome and operational risks increase especially with protective plates on LCD screens
Solution Approach 1:
The patent replaces manual mechanical button pressing or remote control operation with a touch operation device that directly touches the display screen. The touch operation device detects touch positions and gestures, converting them into control signals for picture-in-picture switching and signal source changes, thereby eliminating the need for physical button pressing through protective plates.
Solution Approach 2:
The touch operation device serves as an intermediary between the user and the display system. It captures touch gestures on the display screen, processes them according to preset rules, and generates corresponding control instructions, thus mediating the interaction between user intent and system response without requiring direct mechanical contact with buttons.
2Strength
If protective plates are added to LCD screens to prevent damage, then screen protection is improved, but the complexity of the system increases and operational difficulty arises
Solution Approach 1:
The display screen serves multiple functions: it displays visual information and simultaneously acts as a touch-sensitive control surface. The touch operation device utilizes the display screen's surface for both visualization and input operations, eliminating the need for separate physical buttons and reducing overall system complexity despite the presence of protective plates.
3Strength
If protective plates are added to LCD screens to prevent damage, then screen protection is improved, but ease of operation deteriorates due to reduced tactile feedback
Solution Approach 1:
The patent replaces mechanical tactile feedback from physical buttons with electronic touch detection. The touch operation device detects touch positions, pressure, and gestures through the display screen and protective plate, converting them into control signals without requiring physical button deformation or tactile resistance.
