Solution Overview
Problem
Existing display apparatuses and remote control devices face challenges in recognizing touch inputs from insulators and require large circuit board areas for multiple tact switches, leading to increased manufacturing costs and complexity in providing intuitive and easy operation.
Innovation Solution
A display apparatus with an input unit that includes a single physical function key or touch panel, utilizing a processor to differentiate between short clicks and long presses based on input time, maintaining execution speed within a preset critical time and accelerating it thereafter, while providing on-screen guidance for user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch sensor is used to control display apparatus, then ease of operation is improved, but touch input from insulators cannot be recognized
Solution Approach 1:
The patent changes the detection parameter from electrical conductivity (touch sensor) to optical reflection (light sensor). The light sensor detects changes in reflected light when any material object touches the reflective member, regardless of whether the object is conductive or insulating. This parameter change enables universal touch recognition while maintaining ease of operation.
2Reliability
If jog switch or multiple tact switches are used, then reliability of input recognition is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent makes a single tact switch perform multiple functions by combining it with a light sensor. The same tact switch structure serves both as a physical input device and as part of an optical detection system. This universality reduces the number of components needed while maintaining reliable input recognition through the addition of the light sensor that detects touch regardless of material properties.
Solution Approach 2:
The patent introduces a reflective member as an intermediary between the user's touch and the light sensor. This reflective member transfers the mechanical touch action into an optical signal that the light sensor can detect. The intermediary enables the system to recognize touches from any material without requiring direct electrical contact, simplifying the overall input mechanism.
3Ease of operation
If multiple input devices are used, then ease of operation is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the tact switch and light sensor into a integrated input system. The tact switch provides mechanical input while the light sensor detects the touch through the reflective member. This combination creates a unified input mechanism that offers the ease of operation of touch interfaces without the high manufacturing costs of implementing multiple separate input devices.

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.
