Dynamic Viewing Angle Adjustment for Handheld Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting the viewing angle of handheld electronic devices are inconvenient as they require manual adjustments due to fixed viewing angles, limiting user flexibility and increasing the risk of data snooping when used in public.
Innovation Solution
A method and apparatus that dynamically adjust the viewing angle of a screen using sensors to detect the relative position between the user and the device, allowing for automatic adjustment of the viewing range by transforming liquid crystal material to shield light from unwanted angles, ensuring the user can view the screen comfortably without exposing data to others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed viewing angle is provided to prevent data snooping, then data security is improved, but user convenience deteriorates as manual adjustment is required
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed viewing angle to a dynamically adjustable viewing angle. The liquid crystal screen's viewing angle is automatically adjusted based on the user's position detected by sensors, allowing the system to adapt in real-time. This resolves the contradiction by maintaining data security through angle control while eliminating manual adjustment requirements through automated dynamic adaptation.
Solution Approach 2:
The patent implements feedback by using sensors to detect the user's position and feeding this information back to the control unit, which then adjusts the liquid crystal screen's viewing angle accordingly. This closed-loop feedback mechanism ensures that the viewing angle is continuously optimized for both security and user convenience, resolving the contradiction between fixed security and flexible usability.
2Reliability
If the viewing angle is shrunk to prevent snooping, then data security is improved, but viewing flexibility deteriorates
Solution Approach 1:
The patent applies dynamics by making the viewing angle adjustable rather than fixed. The liquid crystal screen can dynamically change its viewing angle range based on detected user position, providing both the security of a limited viewing angle and the flexibility of adaptation to different viewing scenarios. This resolves the contradiction between security and flexibility.
Solution Approach 2:
The patent changes the parameter of viewing angle dynamically based on user position. By adjusting this key parameter in response to sensor input, the system maintains security (through controlled viewing angles) while achieving flexibility (through parameter adaptation). This resolves the contradiction between fixed security parameters and flexible viewing requirements.
3Reliability
If manual adjustment is required to maintain viewing angle, then data security is maintained, but time efficiency deteriorates
Solution Approach 1:
The patent uses feedback from sensors to automatically adjust the viewing angle, eliminating the need for manual intervention. The control unit receives real-time position data and adjusts the liquid crystal screen accordingly, maintaining security while saving the time that would be spent on manual adjustment. This resolves the contradiction between security maintenance and time efficiency.
Solution Approach 2:
The patent implements self-service by enabling the system to automatically adjust its own viewing angle based on sensor input, without requiring user intervention. The device monitors user position and autonomously optimizes the viewing angle, maintaining security while eliminating time loss associated with manual adjustment. This resolves the contradiction between security and time efficiency.

AI summary
A method and an apparatus for dynamically adjusting a viewing angle of a screen are provided. The method is suitable for dynamically adjusting a viewing range of a screen of a handheld electronic device, wherein the viewing angle of the screen is adjustable. The method is as follows. First, a shifting value of a target deviating from the viewing range of the screen is detected by a sensor. Next, the viewing range of the screen is dynamically adjusted according to the shifting value, so as to cover the target within the viewing range of the screen. Accordingly, the snooping for the content of a frame displayed on the screen by others can be prevented and a user can view the frame displayed on the screen more conveniently.
