Dual Touchscreen Display System for Unobstructed Input Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touchscreen interfaces obstruct the view of the display when users input data, as their hands cover the screen, and existing alternatives like mice, trackballs, or stylus pens are either impractical for portable devices or inadequate for multi-touch gestures.
Innovation Solution
Implementing a dual-touchscreen system where a first touchscreen display is complemented by a second display, allowing information to be shown on both screens simultaneously or separately, enabling a larger input and display area without obstructing the view, and allowing multitasking across applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touchscreen interface is used for input, then the device can be made smaller and less expensive, but the user's hand obstructs the view of the display during input operations
Solution Approach 1:
The display system is segmented into two separate displays: a first touchscreen display for receiving user inputs and a second display for showing detailed information. This segmentation allows the user to interact with the first display while viewing the second display, eliminating the obstruction problem where the user's hand blocks the view during input operations.
2Area of stationary object
If additional input devices like mouse or keyboard are added, then the view obstruction problem is solved, but the device becomes more complex and less portable
Solution Approach 1:
The second display serves multiple functions: it displays detailed information, shows results of touchscreen inputs, and can independently run applications. This multi-functionality eliminates the need for separate external input devices like mice or keyboards, maintaining device portability while providing unobstructed viewing during input operations.
3Area of stationary object
If a larger display area is provided, then more information can be shown, but the device size and cost increase
Solution Approach 1:
Instead of increasing the size of a single display, the system adds a second display in a different spatial dimension, creating a multi-display configuration. This approach provides more total display area and functionality without requiring a single oversized display, maintaining device portability while expanding capabilities.

AI summary
Methods of displaying information on an electronic device have a first touchscreen display and a second touchscreen display are disclosed. As the user enters inputs on the first touchscreen display, the second touchscreen displays the results of the user's inputs on the first touchscreen display. Either touchscreen can be used as an input device. Display information generated by an application can be the same on both displays. Alternatively, the first and second displays comprise a single, larger screen. An single application can address the displays as distinct devices. A touchscreen display can be dedicated to a single application, or a single instance of an application such that the two displays can run different applications, or different instances of the same application. In conjunction with a wireless communications module, the electronic device can be used as a portable teleconferencing device.
