Dual LCD Scroll Control for Seamless Content Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies for mobile terminals with two screens face issues when scrolling, as content may be awkwardly split between screens, leading to poor presentation.
Innovation Solution
A mobile terminal with a control unit that determines display positions for multiple display objects on two screens and receives scroll instructions, displacing objects on one screen while sequentially moving objects from the other screen to maintain seamless scrolling and prevent content splitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional scrolling technology is applied to a mobile terminal with two display screens, then the display screens can show more content, but content may be awkwardly split between screens leading to poor presentation
Solution Approach 1:
The patent divides the display system into two separate display screens (first display screen and second display screen) with distinct scrolling control regions. Each screen can be scrolled independently without affecting the other, preventing content from being awkwardly split across screens while maintaining the ability to display large quantities of content.
2Ease of operation
If scrolling is enabled on both display screens, then user accessibility to content is improved, but content may be displayed incompletely at screen boundaries
Solution Approach 1:
The patent creates separate scrolling control regions for each display screen, allowing independent scrolling operations. This ensures that content remains complete within each screen's display area while maintaining user accessibility to all content through coordinated scrolling of both screens.
3Device complexity
If single-screen scrolling control is used, then the control mechanism is simple, but the user experience is poor when screens are separated
Solution Approach 1:
The patent segments the scrolling control function by providing separate scrolling control regions on each display screen. This maintains relative simplicity in the control mechanism for each screen while significantly improving user experience by allowing independent scrolling without content splitting issues.

AI summary
A mobile terminal 1 is provided with a first LCD 102a, a second LCD 102b, a control unit 109 that determines the display position of each menu image displayed on the first LCD 102a and on the second LCD 102b, and a touch panel 104 that receives a scroll instruction to scroll the display objects displayed on the first LCD 102a and on the second LCD 102b. The control unit 109 displaces the menu images on the first LCD 102a, which is downstream in the direction of scrolling, in accordance with the scroll instruction and then displaces the menu images on the second LCD 102b, which is upstream in the direction of scrolling, sequentially one menu image at a time from the upstream second LCD 102b to the downstream first LCD 102a by displacing a menu image at a position furthest forward in the direction of scrolling.
