Flexible Display Control for Two-Sided Image Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to view and recognize images of obverse and reverse sides simultaneously on a single display screen, especially when images overlap, making existing techniques not user-friendly for two-sided printing previews.
Innovation Solution
A terminal device with a flexible display that can change forms between a folded and extended state, where the display control unit shows a first image corresponding to the obverse side in one region and a second image corresponding to the reverse side in another region, allowing them to be displayed at overlapping positions for intuitive preview.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two images (obverse and reverse sides) are superimposed on one display screen, then both images can be displayed simultaneously, but it becomes difficult for users to view and recognize the images, especially where they overlap
Solution Approach 1:
The display is divided into two separate display regions (first display region and second display region) that are physically separated by bending the flexible display. Each region displays one image (obverse or reverse side), allowing users to view both images simultaneously without overlap confusion while maintaining the ability to see both sides at once
2Device complexity
If a single display screen is used to show both obverse and reverse images, then device complexity is reduced, but user experience deteriorates due to difficulty in recognizing overlapping images
Solution Approach 1:
The flexible display can dynamically change its configuration between folded and extended states. When folded, it creates two spatially separated display regions for viewing both images simultaneously; when extended, it provides a larger single display area. This dynamic reconfiguration allows the system to maintain simplicity while improving image recognition based on user needs
3Measurement precision
If images are displayed at overlapping positions to mimic actual print outcome, then preview accuracy is improved, but user ability to recognize both images simultaneously deteriorates
Solution Approach 1:
Instead of displaying both images in the same two-dimensional space where they would overlap, the flexible display is folded to create three-dimensional spatial separation between the first and second display regions. This allows both images to be viewed simultaneously without overlap while maintaining the ability to represent the obverse-reverse relationship, solving the contradiction between preview accuracy and image visibility

AI summary
A terminal device includes: a display unit configured to take a plurality of forms including a folded form in which the display unit is bent between a first display region and a second display region and an extended form in which the display unit is not bent between the first display region and the second display region; and a display control unit that controls display performed by the display unit. The display control unit causes a first image corresponding to an obverse side to be displayed in the first display region and causes a second image corresponding to a reverse side to be displayed in the second display region, when the display unit is in the folded form.
