Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies, such as LCDs and PDPs, face issues with high power consumption, narrow viewing angles, and low emission efficiency, while EL displays like OLEDs offer high brightness and wide viewing angles but require complex manufacturing processes. Additionally, existing dual display systems lack efficient methods for managing touch inputs and visual information overlap between multiple displays.
Innovation Solution
A dual display apparatus comprising a first display and a second, double-sided emission type display that can rotate and move, with sensors and a controller to determine relative positions and control both displays based on touch and sound inputs, allowing for adaptive activation and deactivation to optimize visual information output and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual display system is implemented to provide multiple visual outputs and interaction surfaces, then user interaction capabilities and visual information display are enhanced, but power consumption increases and system complexity increases
Solution Approach 1:
The system dynamically adjusts display activation based on real-time sensor data detecting cover state and user interaction. The controller activates only the necessary display (first or second) based on whether the second display covers the first, and switches between touch input sources based on detected user interaction patterns, thereby reducing power consumption while maintaining versatility.
Solution Approach 2:
The second display serves multiple functions: it can display information independently, cover the first display to enable alternate interaction modes, and allow touch inputs to be received from either display surface. This multi-functionality enables the system to provide enhanced user interaction capabilities while managing power consumption through selective activation.
2Adaptability or versatility
If a dual display system is implemented to provide multiple visual outputs and interaction surfaces, then user interaction capabilities and visual information display are enhanced, but device complexity increases
Solution Approach 1:
The system segments the display functionality into two independent but coordinated displays, each capable of independent operation. The controller divides the management of touch inputs and visual information between the two displays based on their cover state, allowing enhanced user interaction capabilities while managing complexity through functional segmentation.
Solution Approach 2:
The system uses sensors to detect the cover state and user interaction patterns, providing feedback to the controller. Based on this feedback, the controller automatically adjusts which display is active and which touch input surface is responsive, managing system complexity through automated feedback-based control rather than complex manual configuration.
3Ease of operation
If the second display is activated to provide additional visual information and touch input surface, then user interaction and visual information are enhanced, but power consumption increases
Solution Approach 1:
The system dynamically switches between activating only the first display or activating both displays based on detected user interaction patterns and cover state. When the second display is activated, the controller determines which display should receive touch inputs based on real-time conditions, providing ease of operation while managing power consumption through selective activation rather than continuous operation of both displays.
4Ease of manufacture
If LCDs are used for display, then manufacturing is simplified and display size flexibility is improved, but power consumption increases and viewing angles are limited
Solution Approach 1:
The system merges LCD technology (first display) with a second display type that provides superior brightness and viewing angles. By combining these two display technologies in a dual display configuration with selective activation, the system maintains the manufacturing simplicity and size flexibility of LCDs while compensating for their limitations in brightness and viewing angle through the complementary second display.

AI summary
A dual display including: a first display for displaying first visual information and receiving a touch input; a second display including a double-sided emission display for displaying second visual information through a first surface or a second surface opposite to the first surface, and receiving a touch input; a sensor for sensing relative locations of the first and second displays; and a controller for determining whether or not the second display is covering the first display according to a signal of the sensor, and for controlling the first and second displays. Here, the controller is configured to receive the touch input from the second display when the second display unit covers the first display, and to receive the touch input from the first display when the second display does not to cover the first display.
