Inward-Folding Display Hinge Area for Dual-State Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inward folding electronic devices face challenges in displaying information when in a folded state, necessitating secondary screens that increase material costs and reduce device reliability.
Innovation Solution
Incorporating a semi-transparent and semi-reflective display area at the connecting junction of the device housings, allowing information display on both the front and back based on the device's state, eliminating the need for secondary screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a secondary screen is designed on the non-main screen display area at the back of the inward folding electronic device to display information in the folded state, then information display capability in folded state is improved, but material cost increases and device reliability weakens
Solution Approach 1:
The main screen is designed with semi-transparent and semi-reflective characteristics, enabling it to serve dual functions: displaying information when the device is unfolded and displaying information when the device is folded. This multi-functionality eliminates the need for a separate secondary screen, thereby improving reliability while maintaining adaptability across different device states.
2Adaptability or versatility
If a secondary screen is designed on the non-main screen display area at the back of the inward folding electronic device to display information in the folded state, then information display capability in folded state is improved, but material cost increases
Solution Approach 1:
The main screen is designed with semi-transparent and semi-reflective characteristics, enabling it to serve dual functions: displaying information when the device is unfolded and displaying information when the device is folded. This multi-functionality eliminates the need for a separate secondary screen, thereby reducing material costs while maintaining adaptability across different device states.
Solution Approach 2:
The patent merges the function of the main screen with the secondary screen function by making the main screen semi-transparent and semi-reflective. This combining of functions into a single display component reduces the total quantity of display materials needed and simplifies the overall device structure.
3Adaptability or versatility
If the flexible display module uses a semi-transparent and semi-reflective display area at the connecting area, then information display in both unfolded and folded states is enabled, but display control complexity increases
Solution Approach 1:
The display control system dynamically adjusts the display mode of the semi-transparent and semi-reflective display area based on the device's folding state. When the device is folded, the system activates the semi-transparent mode to display information on the front side; when unfolded, it switches to the semi-reflective mode. This dynamic adaptation enables versatile information display while managing control complexity through state-based logic.

AI summary
An inward folding electronic device includes a first housing, a second housing, and a flexible display module; where a first area of the flexible display module is a semi-transparent and semi-reflective display area, where the first area is corresponding to a connecting area between the first housing and the second housing; and in a case that the electronic device is in an unfolded state, the semi-transparent and semi-reflective display area displays information at a side facing away from the first housing and the second housing; and in a case that the electronic device is in a folded state, the semi-transparent and semi-reflective display area displays information at a side facing towards the first housing and the second housing.
