Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bendable display technologies face challenges in maintaining a consistent acoustic effect for users regardless of the display's bending degree, and they lack the ability to automatically adjust audio based on content type and display curvature.
Innovation Solution
A method for controlling a bendable display device that involves storing screen size information, outputting video and audio content, receiving curvature data, and adjusting audio output based on both the content type and the display's curvature, ensuring a consistent acoustic experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is made bendable to improve immersion, then the viewing experience is enhanced, but the acoustic effect varies depending on the degree of bending
Solution Approach 1:
The patent applies dynamics by making the audio output adaptable to the display's bending state. The system dynamically adjusts audio parameters based on real-time detection of curvature, transforming the static audio output into a dynamic response that compensates for structural changes. This resolves the contradiction by allowing the display to be bendable while maintaining consistent acoustic effects through active adaptation.
Solution Approach 2:
The patent changes audio output parameters (such as volume, frequency, or spatial distribution) based on the detected curvature of the display. By modifying these parameters in response to bending degree, the system maintains consistent acoustic perception despite structural changes. This directly addresses the contradiction by using parameter adjustment to compensate for the variable acoustic effects caused by bendability.
2Reliability
If manual audio adjustment is implemented to compensate for bending, then acoustic effect consistency can be maintained, but user operation complexity increases
Solution Approach 1:
The patent implements self-service by enabling the display device to automatically detect its own curvature and adjust audio parameters without user intervention. The system monitors its structural state and autonomously compensates for acoustic variations, eliminating the need for manual adjustment while maintaining consistent audio output. This resolves the contradiction by making the system self-regulating rather than requiring complex user operations.
Solution Approach 2:
The patent employs feedback by continuously monitoring the display's bending state and using this information to adjust audio output in real-time. The curvature detection creates a feedback loop that automatically compensates for acoustic changes, maintaining consistency without requiring manual user input. This feedback mechanism resolves the contradiction by automating the adjustment process that would otherwise require complex user operations.
3Reliability
If audio is adjusted based on curvature detection, then acoustic effect consistency is maintained, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical audio adjustment mechanisms with a sensing and control system. Instead of physically adjusting audio components based on bending, the system uses curvature sensors and electronic control to modify audio output parameters. This substitution of mechanical systems with sensing and electronic control reduces overall device complexity while maintaining acoustic consistency.
Solution Approach 2:
The patent integrates multiple functions into a unified control system that handles both display bending detection and audio parameter adjustment. By combining these functions, the system avoids the need for separate complex mechanisms for each function, reducing overall device complexity while achieving acoustic effect consistency through the multi-functional control architecture.

The solution provides a consistent acoustic effect to users regardless of the display's bending degree and automatically adjusts audio to better suit the content type and display curvature, enhancing user experience.
Implementation Method 1
a piezo (piezoelectric) vibration sensor is added. The corresponding sensor has a structure in which, as the sensor repeats expansion and compression when power flows therethrough, vibration is transmitted to an OLED panel in contact with the sensor.

AI summary
The present disclosure relates to a bendable display. For example, the bendable display device stores first information about a size of a screen of the bendable display device in a memory, outputs video data and audio data of content via the screen, receive second information about a curvature of the screen, and output the audio data adjusted based on the first information and the second information via the screen.
