Dual-Screen Device Segmented Displays for Viewing and Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices like smartphones and tablets face limitations in viewing digital images from angles opposite the display and in composing documents due to space constraints and the inflexibility of conventional electronic keyboards.
Innovation Solution
The implementation of dual-screen electronic devices with rotatable and detachable displays, allowing for a secondary screen to function as an adjustable keyboard and to demonstrate photo/video output, with customizable button sizes, positions, and shapes, and the ability to be used as a touch-pad for mouse-like functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display is mounted on the device, then the device structure remains simple, but the user cannot view digital images from angles opposite the display
Solution Approach 1:
The display system is segmented into multiple independent display units (first display and second display) that can be positioned at different orientations. The first display is mounted on the first housing and the second display is mounted on the second housing, allowing them to be oriented in opposite directions to enable viewing from multiple angles simultaneously.
Solution Approach 2:
The patent transitions from a single-plane display to a multi-dimensional display arrangement by mounting displays on opposite sides of the device housing. This spatial arrangement in three-dimensional space enables users to view content from angles that would be impossible with a single display, effectively adding a dimensional aspect to the viewing experience.
2Adaptability or versatility
If the display shows a document being composed, then the composition space is limited, but the available space for displaying both document and keyboard is insufficient
Solution Approach 1:
The display area is segmented between two separate displays: the first display shows the document being composed while the second display shows the electronic keyboard. This segmentation allows each display to be optimized for its specific function without space constraints, as each display can be positioned to provide adequate area for its intended purpose.
Solution Approach 2:
The second display serves multiple functions: it displays the electronic keyboard for text input, and can also function as a touch-pad for mouse-like functionality. This multi-functionality maximizes the utility of the display area without requiring additional dedicated space for each function.
3Adaptability or versatility
If a conventional electronic keyboard is used, then the keyboard structure is simple, but the keyboard is not customizable beyond preset views
Solution Approach 1:
The electronic keyboard displayed on the second display is made dynamic and customizable rather than static. Users can adjust the size of keyboard buttons, reposition keys, and change their shapes according to personal preferences or specific tasks. This dynamic reconfigurability transforms the keyboard from a fixed preset to an adaptable interface.
Solution Approach 2:
The keyboard customization capability allows users to change various parameters of the keyboard display including button size, position coordinates, and shape geometry. These parameter modifications enable the same physical display to present different keyboard configurations, providing extensive customization without adding physical hardware complexity.
4Adaptability or versatility
If the device uses a fixed display orientation, then the manufacturing process is simple, but the device cannot demonstrate photo/video output effectively
Solution Approach 1:
The display system is divided into separate mounting locations on different housings, allowing each display to be independently positioned and oriented. This segmentation enables the first display to show photo/video output from one direction while the second display can be oriented to show the same content from the opposite direction, providing comprehensive viewing capability.
Solution Approach 2:
By mounting displays on opposite sides of the device and allowing them to be oriented in different directions, the patent creates a three-dimensional display arrangement. This multi-dimensional configuration enables effective demonstration of photo/video output from multiple viewing angles, transforming a two-dimensional display limitation into a three-dimensional viewing advantage.

AI summary
Systems and methods for dual-screen electronic devices are provided in which, at a dual-screen electronic device having a first housing and a second housing attached by a hinge, a first processor, a first display mounted to the first housing, where the first display includes a first touch-sensitive surface, a second display mounted to the second housing, and a first memory contained within the first housing, a first user interface is displayed on the first display and a second user interface, different from the first user interface, is displayed on the second display. While displaying the first and second user interfaces, a user input is detected on the first display and, in response, a display of the second user interface, displayed on the second display, is changed. Separately is presented a user-adjustable-keyboard software-application.
