Solution Overview
Problem
Existing display apparatuses face challenges in providing intuitive and cost-effective input methods, as touch sensors may not recognize insulators and require large circuit board areas for jog switches or tact switches, leading to increased manufacturing costs and complexity.
Innovation Solution
A display apparatus with an input unit that includes a single physical function key or touch panel, utilizing a processor to distinguish between short clicks and long presses based on input time, maintaining execution speed within a preset critical time and accelerating it thereafter, while guiding functions through on-screen displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch sensor is used to perform touch operations, then the display apparatus can recognize conductive inputs, but insulators cannot be recognized and the system becomes less versatile
Solution Approach 1:
The input unit is designed to accept multiple types of input materials (conductive and insulative) by using a single sensor structure that detects both capacitive and resistive touch patterns, making the system universal in handling different input types without requiring separate sensors for each material type
Solution Approach 2:
The system changes detection parameters dynamically based on the detected input type. When an insulator is detected, the sensor switches to resistive touch detection mode; when a conductor is detected, it uses capacitive touch detection mode. This parameter adaptation allows reliable recognition of both insulators and conductors
2Reliability
If jog switches or tact switches are used for control, then reliable input recognition is achieved, but manufacturing costs increase and circuit board area requirements increase
Solution Approach 1:
Multiple input functions (touch, press, slide, rotation) are merged into a single sensor unit, eliminating the need for separate jog switches and tact switches. This consolidation reduces the number of components, simplifies manufacturing, and decreases circuit board area requirements while maintaining reliable input recognition
Solution Approach 2:
The single sensor unit performs multiple input detection functions that traditionally required separate components, providing universal input capability across different interaction types while reducing manufacturing complexity and cost
3Ease of operation
If a single input device is used to operate the display apparatus, then ease of operation and intuitiveness are improved, but the device complexity is reduced which may limit functionality
Solution Approach 1:
The single input device incorporates dynamic detection capabilities that adapt to different user interactions (tap, press duration, sliding motion, rotational motion). The sensor dynamically adjusts its detection parameters and interpretation of input signals based on the detected motion pattern, enabling intuitive operation with a simplified physical structure

AI summary
A display device is provided. The display apparatus includes: a display configured to display a user interface screen; an input interface configured to receive a user operation to select and execute at least one menu item included in the user interface screen; and a processor configured to separately recognize a short click and a long press based on an input time of the user operation, constantly maintain an execution speed of a function corresponding to a selected menu item within a preset critical time in the time for which the input of the long press is continued and accelerate the execution speed of the corresponding function after the preset critical time passes.
