Split-Screen Laptop Display With Inward-Folding Screen Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split-screen displays for laptop computers expose one screen's display face when folded, risking damage during storage or transportation.
Innovation Solution
A split-screen display device with biaxial hinges connecting screens to a middle plate member, allowing screens to fold with display faces obscured by each other, reducing exposure and protecting the screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the two screens are rotated separately, one forward and one backward when folding, then the split-screen display can be compactly folded, but one screen's display face will be exposed and vulnerable to damage
Solution Approach 1:
The patent applies the inversion principle by changing the folding direction of the screens. Instead of rotating one screen forward and one backward (which exposes a display face), both screens are rotated in the same direction (forward) so that their display faces are tucked inward against the bracket, eliminating exposure and vulnerability to damage during storage or transportation.
2Object-affected harmful factors
If both screens are rotated forward when folding, then the display faces are protected, but the folding mechanism becomes more complex
Solution Approach 1:
The patent applies asymmetry by introducing a limiting component that allows both screens to rotate forward but prevents them from rotating beyond a certain angle. This asymmetric constraint ensures the display faces remain protected while the limiting component guides the folding motion, preventing over-rotation and simplifying the user's folding operation without requiring complex mechanisms.

AI summary
The present application relates to a split-screen display device for a laptop computer. The first screen and the second screen are provided on the left and right sides of the middle plate member, respectively; and the middle plate member forms a hinge connection with the first screen on one side by a first biaxial hinge assembly, and the middle plate member forms a hinge connection with the second screen on the other side by a second biaxial hinge assembly, wherein when the split-screen display device is in a completely folded state, the first screen is folded on a front face of the middle plate member and the second screen is folded on a back face of the first screen. When completely folded, both the first screen and the second screen have their display faces covered and protected, thus reducing the risk that the display faces are damaged.
