Rollable Display Unrolling for Seamless Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large image display apparatuses face issues with increased power consumption and aesthetic concerns due to their size, necessitating a solution for a variable display size that allows for efficient use and seamless video playback.
Innovation Solution
An image display apparatus featuring a rollable display, a driving unit to change its size, and a controller that receives signals from a remote controller to unroll the display while displaying a video on the remote controller during unrolling, ensuring seamless video playback once fully unrolled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display size is increased to provide high quality image output, then the image quality is improved, but power consumption increases and aesthetic appearance deteriorates when not in use
Solution Approach 1:
The display device transitions from a static large display to a dynamic rollable display that can change its visible area. The display panel is rolled up into a housing when not in use and unrolled when needed, allowing the system to provide large display quality when required while minimizing power consumption and aesthetic impact when not in use.
Solution Approach 2:
The rollable display panel is nested within the housing of the display device. When not in use, the display panel is rolled up and stored inside the housing, making the device compact and aesthetically pleasing. When needed, the display unrolls from the housing to provide a large viewing area for high quality image output.
2Illumination intensity
If the display size is increased to provide high quality image output, then the image quality is improved, but the aesthetic appearance deteriorates when the device is not used
Solution Approach 1:
The display device transforms from a permanently large structure to a dynamic system that adjusts its visible footprint. The rollable display can be compacted into the housing when not in use, presenting a sleek, space-efficient form factor, and expanded when needed to provide a large display area for high quality images.
Solution Approach 2:
The large display panel is nested within the compact housing when not in use, creating a space-efficient and aesthetically pleasing appearance. When needed, the display unrolls from the housing to provide a large viewing area, maintaining the housing's compact aesthetic while enabling large display functionality.
3Illumination intensity
If the rollable display is unrolled to provide video playback, then the viewing experience is improved, but the time required to prepare for playback increases
Solution Approach 1:
The video content is displayed in advance on the remote controller's display while the rollable display is unrolling. This preliminary action allows the user to see what will be played on the large display during the unrolling process, eliminating idle time and making the transition to full playback seamless.
Solution Approach 2:
The remote controller's display serves as an intermediary device during the unrolling process. It temporarily displays the video content that will soon be shown on the large rollable display, bridging the gap during the transition period and ensuring continuous visual engagement without loss of viewing time.
