Flexible Display Folded by Rotatable Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronics devices, such as mobile phones, have small rigid displays that are inadequate for various applications, as users prefer larger display sizes for gaming and video applications, but material and technology constraints hinder the adoption of flexible display technology in these devices.
Innovation Solution
A mobile phone design incorporating a flexible display with a rotatable hinge or link hinge mechanism that allows the display to be folded to different angles, providing a compact form factor while enabling larger viewing sizes, with operation modes automatically selected based on the display's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid display is used in a mobile phone, then the display provides stable viewing, but the device size is increased and portability is reduced
Solution Approach 1:
The patent applies flexible display technology that can be bent and folded, replacing traditional rigid displays. This allows the display to maintain stability while enabling compact folding configurations that reduce overall device volume when closed, directly resolving the contradiction between display stability and device size.
2Area of stationary object
If a larger display size is used, then viewing area is improved, but the device becomes less portable and harder to carry
Solution Approach 1:
The patent divides the large display into two separate parts that can be folded together. This segmentation allows the display to provide a large viewing area when unfolded while enabling compact portability when folded, directly resolving the contradiction between display area and portability.
Solution Approach 2:
The patent implements a folding mechanism where one display part is nested within or adjacent to the other part when folded. This nesting approach allows the large display area to be compacted into a smaller form factor for carrying, directly addressing the contradiction between display size and portability.
3Adaptability or versatility
If flexible display technology is adopted, then display flexibility and compactness are improved, but manufacturing complexity and material constraints increase
Solution Approach 1:
The patent divides the flexible display into two separate manageable parts rather than attempting to fold a single large flexible display. This segmentation reduces manufacturing complexity by allowing each part to be produced and tested independently before assembly, while still achieving the desired flexibility and compactness.

AI summary
Embodiments are provided for mobile phones, and similar sized electronics devices, with flexible displays, which allow suitable viewing sizes for different applications. The embodiment devices combine, into one compact package, the benefits of a small carry size with those of a large display. An embodiment mobile phone with a flexible display includes a first part having a first surface and a first edge, and a second part having a second surface and a second edge. A rotatable hinge couples the first edge of the first part is coupled to the second edge of the second part. The flexible display of the mobile phone is a continuous flexible display which has a back surface disposed on the first surface of the first part and on the second surface of the second part. The viewing surface of the flexible display is opposite to the back surface.
