Solution Overview
Problem
Conventional foldable electronic devices with flexible displays face challenges in maintaining an optimal video orientation suitable for different use scenarios, particularly when the flexible display is bent, as users struggle to operate touch panels effectively.
Innovation Solution
A foldable electronic device featuring a first and second display unit that can rotate about a front-rear axis, equipped with an angle and angular velocity acquisition unit to dynamically adjust the video orientation based on the angle and velocity, ensuring the display direction matches the intended use scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display unit is bent to enable foldable usage, then adaptability to different use scenes is improved, but the ease of operation deteriorates because users struggle to operate touch panels when bent
Solution Approach 1:
The display orientation dynamically changes based on the detected bending state. The control unit adjusts the display orientation according to the angle detected by the sensing unit, making the display adaptive to different folding states rather than fixed, thereby resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The sensing unit continuously detects the bending angle and provides feedback to the control unit, which then adjusts the display orientation accordingly. This closed-loop feedback mechanism ensures the display automatically adapts to the current folding state, maintaining ease of operation across different adaptability scenarios
2Adaptability or versatility
If the display orientation is fixed, then device complexity is reduced, but adaptability to different use scenes deteriorates
Solution Approach 1:
The display unit serves multiple functions by automatically adjusting its orientation based on folding state. A single display structure achieves both fixed simplicity and adaptive multi-functionality by responding to different bending angles, eliminating the need for separate display configurations for different use scenes
Solution Approach 2:
The display orientation parameter changes dynamically based on the bending angle parameter detected by the sensing unit. By changing the display orientation parameter according to the folding state, the system achieves adaptability without adding complex hardware, only modifying the display parameter based on detected conditions

AI summary
An electronic device is provided that includes a first display unit including a first display; a second display unit including a second display disposed on a side of the first display and being rotatable with respect to the first display unit about a rotation axis extending in a front-rear direction such that an angle formed by the first and displays change; an angle and angular velocity acquisition unit that acquires the angle formed by the first and second displays and angular velocity of the angle; and a control unit that, when a user rotates the second display unit with respect to the first display unit, determines whether a horizontal direction of a video to be displayed on the first and second displays is made to match a vertical direction or a left-right direction based on the angle and the angular velocity acquired by the acquisition unit.
