Foldable Display Processing for Browsability and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable data processing devices with large screens face a trade-off between high browsability and portability, as they are prone to damage from accidental drops and are less portable compared to smaller screens.
Innovation Solution
A data processing device with a foldable display portion and a sensor that senses its state, allowing the device to execute different processing based on its folded configuration, enabling it to be both highly browsable and portable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large screen is used to improve browsability, then the display area increases, but the device becomes less portable and more prone to damage
Solution Approach 1:
The display device is divided into multiple panels that can be folded independently. Each panel can be separated or combined, allowing the device to transition between a compact folded state for portability and an extended unfolded state for increased display area and browsability.
Solution Approach 2:
The display device incorporates a foldable structure with movable connections between panels, enabling dynamic reconfiguration. The device can adapt its physical form between folded and unfolded states, providing both portability when folded and expanded display area when unfolded, thus resolving the contradiction between these two requirements.
2Area of stationary object
If a large screen is used to improve browsability, then the display area increases, but the device becomes more susceptible to damage from accidental drops
Solution Approach 1:
By dividing the display into multiple separable panels, the device reduces the risk of catastrophic damage. If one panel is damaged, the other panels may remain functional. The segmented structure also allows the panels to be folded or detached to protect them from impact during accidental drops.
Solution Approach 2:
The foldable structure inherently provides protection by allowing the panels to be folded or positioned in a compact configuration that reduces their exposure to external impacts. This preemptive positioning protects the display area from damage before accidental drops occur.
3Ease of operation
If the device is made portable by reducing size, then ease of carrying improves, but the display area decreases
Solution Approach 1:
The display is segmented into multiple panels that can be folded together to create a compact form factor for enhanced portability. When carrying is needed, the panels are folded into a small package. When browsing or viewing content, the panels can be unfolded to provide a large total display area, thus achieving both portability and large display area at different times.
Solution Approach 2:
The device employs a dynamic foldable structure that allows seamless transition between compact and expanded states. This dynamic capability enables the device to optimize its form factor based on usage context—compact for portability and expanded for browsability—resolving the contradiction between these two opposing requirements.

AI summary
To provide a highly browsable data processing device or a highly portable data processing device, a data processing device including the following is devised: an input/output unit provided with a display portion which can be folded and unfolded and a sensor portion that can sense the folded and unfolded states of the display portion and can supply data on fold, and an arithmetic unit that stores a program for executing different processing depending on the data on fold.
