Double-Sided Display Device Rear Camera Selfie Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively control applications on an electronic device with a double-sided display while minimizing battery consumption and reducing the frequency of malfunctions due to unintended inputs, particularly when the device has a front camera that occupies a significant bezel area, impacting the screen size and selfie-taking functionality.
Innovation Solution
The implementation of an electronic device with two touch screen displays allows for efficient application control using both screens, where the rear camera is utilized for various purposes, and the front display area is maximized by removing the front camera and using alternative authentication methods, such as a fingerprint sensor or soft buttons, to reduce bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front camera is disposed on the front surface to provide selfie-taking function, then the camera function is improved, but the bezel area increases and screen area decreases
Solution Approach 1:
The patent merges the selfie-taking function with the rear camera by utilizing the rear camera for both regular photography and selfie functions. The rear camera module serves dual purposes, eliminating the need for a separate front camera and thereby reducing bezel area while maintaining screen size.
Solution Approach 2:
The patent inverts the conventional camera arrangement by using the rear camera for selfie-taking instead of placing a camera on the front surface. Users take selfies by positioning the rear camera to face themselves, which eliminates the front camera requirement and reduces bezel area.
2Area of stationary object
If a double-sided display is implemented to maximize front screen area, then screen area is improved, but battery consumption increases and unintended inputs occur
Solution Approach 1:
The patent implements dynamic control of the rear display, allowing it to be activated or deactivated based on usage context. The rear display can be turned off when not needed for application control, reducing power consumption, while remaining available when needed for dual-sided interaction scenarios.
Solution Approach 2:
The patent segments the display functions by assigning different roles to front and rear displays based on application context. The front display handles primary user interaction while the rear display provides supplementary control when needed, allowing selective activation to optimize power consumption.
3Area of stationary object
If a double-sided display is implemented to maximize front screen area, then screen area is improved, but the frequency of malfunction due to unintended inputs increases
Solution Approach 1:
The patent implements preliminary anti-action by detecting and preventing unintended inputs before they cause malfunctions. The system monitors touch patterns on the rear display and distinguishes between intentional user interactions and unintended touches (such as those from holding the device), blocking only the latter to prevent errors.
Solution Approach 2:
The patent uses feedback mechanisms to distinguish between intentional and unintentional inputs on the rear display. By analyzing touch characteristics, timing, and context, the system provides feedback to determine whether a touch was intentional, allowing selective response to reduce malfunctions from unintended inputs.
4Adaptability or versatility
If conventional application execution method is used on double-sided display, then application compatibility is improved, but battery consumption increases and malfunction frequency increases
Solution Approach 1:
The patent implements dynamic application execution modes that adapt to the usage context. Applications can run in conventional single-sided mode for compatibility while consuming less power, or switch to dual-sided mode when enhanced functionality is needed, optimizing both compatibility and power consumption based on real-time requirements.

AI summary
An electronic device is disclosed. The electronic device may include a front display and a rear display, a touch panel to sense a user input, a camera disposed on a rear surface of the electronic device, and at least one processor. The at least one processor may output an image, which is obtained by the camera in a first shooting mode, to the rear display, output the image, which is obtained by the camera in a second shooting mode, to the front display, and control the camera in response to the user input sensed to the front display. Moreover, various embodiment found through the disclosure are possible.
