Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals face challenges in performing various user inputs due to their small display area, making it cumbersome to use stylus pens for precise operations, and often require additional tasks like carrying and storing the stylus, which limits the adoption of pen-based inputs.
Innovation Solution
A pen function system that includes a touch pen with a coil and actuator to generate a magnetic field, allowing for precise gesture recognition and command execution on a pen recognition panel, enabling faster and more convenient operation of electronic device functions without the need for physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stylus pen is provided for precise input operations on a small display, then input precision is improved, but device complexity and ease of operation deteriorate due to the need to carry and store the stylus
Solution Approach 1:
The mobile terminal itself provides the pen function through its display panel, eliminating the need for a separate stylus. The display panel detects pen inputs directly, allowing the device to serve its own input needs without external accessories.
Solution Approach 2:
The display panel is designed to perform multiple functions: it serves as both the visual display and the input detection surface. By integrating pen input detection into the display panel, the device combines display and input functions into a single component.
2Measurement precision
If a stylus pen is used for precise input operations, then input precision is improved, but device complexity increases due to additional components
Solution Approach 1:
The pen input detection function is merged with the display panel, combining two separate functions (display and input detection) into a single integrated component. This eliminates the need for separate stylus hardware and reduces overall system complexity.
Solution Approach 2:
The display panel is designed to perform multiple functions: it serves as both the visual display and the input detection surface. By integrating pen input detection into the display panel, the device combines display and input functions into a single component.
3Ease of operation
If finger touch is used for input operations, then ease of operation is improved, but input precision deteriorates due to larger contact area
Solution Approach 1:
The system dynamically adapts to different input methods by detecting whether the input comes from a finger or a pen. The display panel can recognize the difference between finger touches and pen inputs, allowing it to optimize its response based on the input device being used.

AI summary
An apparatus and method for operation of a pen function in an electronic device. A pen recognition panel recognizes a touch pen according to a set mode. A control unit collects pen status information including at least one of information on an arrangement state between a pen recognition panel and a touch pen and a state information on whether a button of the touch pen is pushed, type information on a currently activated application program, and a gesture recognition information according to a gesture input operation of the touch pen, or collects the pen status information and the gesture recognition information. A storage unit stores a pen function table providing a pen function command corresponding to collected information according to the set mode. display panel displays information according to performing of a function corresponding to the pen function command.
