Solution Overview
Problem
Conventional display apparatuses lack satisfactory compatibility and association between display panels and haptic devices, which are typically separate and unable to effectively represent multiple senses such as tactile and thermal sensations simultaneously.
Innovation Solution
A haptic panel integrated with a display apparatus, featuring sensing units with semiconductor modules and electrodes, capable of representing tactile and thermal sensations through electrical signals, enhancing compatibility and efficiency by providing both touch determination and sensory representation on a single panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional haptic display apparatus includes an additional haptic device provided independently from the display panel, then the haptic device can provide tactile feedback, but the compatibility between the display panel and the haptic device is not satisfactory
Solution Approach 1:
The patent combines the display panel and haptic device into a single integrated structure where the haptic actuator is positioned behind the display panel. This merging eliminates the need for separate independent components while maintaining both display and haptic functions, thereby improving compatibility without significantly increasing overall device complexity
Solution Approach 2:
The integrated haptic display apparatus serves multiple functions through a unified structure: it provides both visual display through the display panel and tactile feedback through the haptic actuator positioned in close proximity. This multi-functionality allows a single device to replace what would traditionally require separate components
2Adaptability or versatility
If the haptic device is controlled independently from the display panel, then the haptic device can operate autonomously, but the operation of the haptic device is not sufficiently associated with the operation of the display panel
Solution Approach 1:
The integrated structure enables natural feedback association between display and haptic operations. Since the haptic actuator is positioned directly behind the display panel, tactile feedback can be precisely correlated with visual content being displayed, creating an associative control relationship without requiring complex independent control systems
3Adaptability or versatility
If multiple sensing units are integrated in a single haptic panel to represent tactile and thermal senses, then various senses can be provided to a user, but the device structure becomes more complex
Solution Approach 1:
The haptic panel is divided into multiple sensing units, each capable of representing different tactile and thermal senses. This segmentation allows diverse sensory representation while maintaining a modular structure that manages complexity through repeated standardized elements rather than a monolithic complex design
Solution Approach 2:
Each sensing unit in the haptic panel is designed to provide multiple sensory functions (tactile and thermal representation) through a unified structure. This multi-functionality at the unit level reduces overall system complexity compared to having separate dedicated components for each sensory modality
