Display Panel Vibration Generator Touch Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in providing an immersive viewing experience due to separate speakers that direct sound away from the viewer and occupy valuable space, and they often require additional input devices that compromise design and user convenience.
Innovation Solution
A display apparatus incorporating a vibration generator that serves as a touch sensor and sound output mechanism, allowing for touch pressure sensing and sound emission towards the viewer while eliminating the need for separate input devices and speakers, thereby enhancing design aesthetics and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a separate speaker is provided in the display apparatus, then sound output capability is improved, but the sound progresses toward side or upper/lower ends instead of toward the viewer, reducing immersion level
Solution Approach 1:
The patent combines the speaker function with the display panel by making the display panel itself serve as the sound-generating surface. The vibration generator is positioned behind the display panel to vibrate the panel directly, merging the visual display function with audio output function into a single integrated component, thereby directing sound toward the viewer while maintaining immersion.
Solution Approach 2:
The display panel is designed to perform multiple functions simultaneously: it serves as both the visual display surface and the sound-generating surface. By making the display panel universal for both imaging and audio output, the patent eliminates the need for separate speakers and improves sound directionality toward the viewer.
2Power
If a separate speaker is provided in the display apparatus, then sound output capability is improved, but the speaker occupies certain space, causing restriction in design and space arrangement
Solution Approach 1:
The patent merges the speaker function into the display panel structure itself, eliminating the need for a separate speaker component. The vibration generator is integrated behind the display panel, allowing sound output without occupying additional space that would restrict design flexibility.
Solution Approach 2:
The display panel is designed to serve dual purposes: visual display and sound generation. This multi-functionality eliminates the need for separate speaker space, thereby freeing up design space while maintaining sound output capability.
3Adaptability or versatility
If an input device is arranged on the front surface of the display panel, then input functionality is provided, but the display area is reduced
Solution Approach 1:
The patent merges the input device functionality with the display panel by enabling the display panel itself to serve as a touch-sensitive input surface. The vibration generator and its components are utilized to detect touch pressure, combining the display function with input sensing function into the same surface area.
Solution Approach 2:
The display panel is designed to perform multiple functions simultaneously: visual display, sound generation, and input sensing. By making the display panel universal for all these functions, the patent provides input functionality without reducing the display area, as no separate physical input device is needed.
4Area of stationary object
If an input device is arranged on a side or rear surface of the display panel, then display area is preserved, but design restrictions and user inconvenience occur
Solution Approach 1:
The patent combines the input sensing function with the front display surface by utilizing the vibration generator components behind the panel for touch detection. This integration allows the input device to be effectively positioned on the front surface without physically adding components that would reduce display area.
