Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touchscreen devices fail to recognize the use of a stylus, leading to the inability to automatically execute applications suitable for stylus operations.
Innovation Solution
A display system comprising a touchscreen display with a sensor to detect the presence or absence of a stylus, enabling communication with a terminal device and controlling it based on stylus movements, allowing for the execution of specific applications or modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a stylus is used to command the touchscreen device, then the user can perform writing or drawing operations, but the touchscreen device cannot automatically recognize stylus usage and execute suitable applications
Solution Approach 1:
The system performs preliminary actions by pre-configuring multiple application modes and using sensors to detect stylus presence before user interaction begins. This allows the system to automatically determine when a stylus is being used and switch to the appropriate application without requiring manual user configuration.
Solution Approach 2:
The system employs sensors to continuously monitor whether a stylus is near the touchscreen and provides feedback to the control circuit. Based on this feedback, the system automatically switches between different application modes, enabling automatic recognition of stylus usage without manual intervention.
2Adaptability or versatility
If the touchscreen display continuously monitors stylus presence, then automatic application switching is enabled, but additional sensors and processing are required
Solution Approach 1:
The system uses a multi-functional approach where existing touchscreen components serve dual purposes. The sensors that detect touch interactions are also used to detect stylus presence, and the existing application execution framework is extended to support automatic mode switching, thereby reducing the need for entirely separate monitoring systems.
Solution Approach 2:
The control circuit acts as an intermediary that receives sensor signals and translates them into application switching commands. This intermediary layer simplifies the overall system architecture by centralizing the decision-making logic for application selection based on stylus detection, rather than requiring direct complex interactions between multiple components.

Data Source
AI summary
A display system and a display method are provided. The display system comprises: a stylus, a touchscreen display, and a terminal device. The touchscreen display comprises a frame and a sensor. The sensor detects whether the stylus is near the frame. The terminal device communicatively connects to the touchscreen display. In response to the stylus being moved away from the frame, the touchscreen display transmits an operation signal to the terminal device and controls the terminal device according to the operation signal.
