Multi-Display System for Simultaneous Page Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems struggle to allow viewers to simultaneously view multiple pages of image data, and user-input information is not accurately reflected across display devices when switching between pages.
Innovation Solution
A display system comprising multiple side-by-side display devices, an input detection device, and a control device that manages image data display, reflects user input, and performs page operations, ensuring that user-input information is accurately displayed across all devices even when pages are shifted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pages of image data are switched one by one on a single display device, then the display device can show one page at a time clearly, but the viewer cannot view multiple pages simultaneously
Solution Approach 1:
The patent divides the display system into multiple independent display devices (first display device, second display device, etc.) arranged side by side. Each display device shows a different page of image data, allowing viewers to see multiple pages simultaneously. This segmentation of the display function across multiple devices directly resolves the contradiction by enabling multi-page viewing while maintaining clear individual page display.
2Quantity of substance
If image data is displayed on multiple display devices using screen capturer, then the same image data is shown on all devices, but the viewer still cannot view different pages at once
Solution Approach 1:
The patent assigns different display content to different display devices based on their positions. The first display device displays the first page, the second display device displays the second page, and so on. This local differentiation of display content across multiple devices allows each device to show relevant page information while collectively providing multi-page viewing capability, resolving the contradiction between using multiple devices and displaying varied content.
3Loss of information
If user inputs explanatory notes on image data displayed on one device, then the notes are reflected on that device, but the notes are not reflected when switching to different pages on other devices
Solution Approach 1:
The patent implements a feedback mechanism where the control device receives input information from the input detection device about user annotations on displayed image data. The control device then transmits this input information to the appropriate display devices, ensuring that explanatory notes and user inputs are reflected on the corresponding pages. This feedback loop maintains information consistency across multiple display devices when navigating between pages.
4Quantity of substance
If multiple display devices are used to show different pages, then viewers can see multiple pages, but the system complexity increases
Solution Approach 1:
The control device serves multiple functions: it manages image data transmission to multiple display devices, receives input information from the input detection device, stores user inputs in its storage unit, and transmits relevant input information back to the appropriate display devices. This multi-functionality consolidates the system's complexity into a single control unit, allowing multiple display devices to work together seamlessly without proportionally increasing overall system complexity.

AI summary
A display system displays, on each of a plurality of display devices arranged side by side, among image data of a plurality of pages, each of image data of the number of display devices, and reflects input information, which indicates information input by a user, on image data displayed on a master display device among the plurality of display devices. Moreover, the display system displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of image data which is obtained by shifting the image data of the number of display devices in accordance with an operation on a page operation unit. Thereby, a viewer is able to view image data of several pages at once, and it is possible to reflect information input by a user even when image data of a target page is shifted backward or forward.
