Display Panel Sound Generation via Object Location Gain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices struggle to provide realistic sound that synchronizes with the location of objects in displayed images, leading to a lack of immersive audio-visual experience.
Innovation Solution
A method and device that calculate gain values based on the location of objects in images, applying these values to sound data to adjust sound output from multiple sound generating devices, creating the illusion that sound is originating from specific objects within the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound is output from fixed位置的 speakers, then device structure is simple, but sound does not match object location in image
Solution Approach 1:
The display panel is divided into multiple regions, with independent sound generating devices disposed in each region. This segmentation allows sound to be produced from multiple locations corresponding to different areas of the displayed image, enabling sound to match object locations while maintaining a relatively simple device structure by using the display panel itself as the sound output medium
Solution Approach 2:
The display panel serves dual functions: displaying images and generating sound. By integrating sound generating devices directly into the display panel structure, the system achieves multi-functionality without adding separate dedicated sound output components, thus improving sound location accuracy while controlling device complexity
2Measurement precision
If gain values are applied to adjust sound output, then sound realism is improved, but processing complexity increases
Solution Approach 1:
Gain values are pre-calculated based on object locations in the displayed image before sound output. This preliminary calculation allows the system to store and retrieve appropriate gain values during sound generation, reducing real-time processing complexity while maintaining accurate sound-image matching
Solution Approach 2:
The system continuously monitors object locations in the displayed image and dynamically adjusts gain values applied to sound data. This feedback mechanism ensures sound remains synchronized with moving objects, improving matching accuracy while using efficient algorithms to minimize processing complexity

AI summary
A method of providing sounds matching an image displayed on a display panel includes: calculating a first object in the image by analyzing digital video data corresponding to the image, and calculating first gain values based on a location of the first object, and applying first gain values to a plurality of sound data; displaying the image on the display panel based on the digital video data; and outputting the plurality of sounds by vibrating the display panel based on the plurality of sound data to which the first gain values applied, using a plurality of sound generating devices.
