Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display screens in mobile devices face issues with poor hardness, leading to surface collapse when unsupported, and support structures either restrict bending or lack sufficient structural strength.
Innovation Solution
A display module with a support member comprising a first connection plate made of metal parts with grooves and organic material parts, and buffer members to absorb stress, ensuring flexibility and support without hindering bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If a liquid crystal display is used to achieve a thin and lightweight display device, then the display module becomes more suitable for mobile devices, but the display module requires voltage application to maintain its state, which consumes power
Solution Approach 1:
The display module is segmented into two independent stacks: a first stack containing the liquid crystal display components that can be turned off, and a second stack containing the always-on display components. This segmentation allows the liquid crystal display to be powered down completely when not in use, eliminating its power consumption, while maintaining display functionality through the second stack.
Solution Approach 2:
The liquid crystal display operates in periodic cycles, being activated only when full display functionality is needed and deactivated during always-on display modes. This periodic operation reduces overall power consumption by keeping the power-hungry liquid crystal components inactive during periods when simpler display modes suffice.
2Length of moving object
If a liquid crystal display is used to achieve thin and lightweight design, then portability is improved, but the display cannot maintain its state without continuous voltage application
Solution Approach 1:
The display functionality is segmented into multiple independent stacks that can operate autonomously. The first stack with liquid crystal components can be completely powered off, eliminating the need for continuous voltage application to maintain state, while the second stack provides always-on display capability.
Solution Approach 2:
The patent implements an always-on display stack that creates a simplified copy of the full display functionality. This second stack maintains essential display capabilities without requiring the voltage-dependent liquid crystal components, allowing the display to show information persistently without continuous power application to the main liquid crystal layer.
3Use of energy by stationary object
If the display module is turned off completely to save power, then power consumption is reduced, but the display functionality is lost
Solution Approach 1:
The display system is divided into two functional stacks: a first stack that can be completely powered off to save power, and a second stack that remains active to maintain essential display functionality. This segmentation allows the device to adapt between full power mode and power-saving mode without completely losing display capabilities.
Solution Approach 2:
The display module dynamically switches between different operational states by activating or deactivating different stacks based on power requirements. The system can transition from full liquid crystal display operation to always-on display mode or complete power-off state, providing adaptive versatility across different usage scenarios.

AI summary
This application provides a display module and an electronic device. A display screen of the display module includes a first buffer member, and a first non-bending region, a bending region, and a second non-bending region that are successively connected. A support member is fastened on a non-display side of the display screen. A first metal plate member of the support member faces the first non-bending region. A first connection plate member of the support member faces the bending region. A second metal plate member of the support member faces the second non-bending region. The first connection plate member is capable of being bent. A metal part of the first connection plate member is provided with a plurality of grooves. Openings of the plurality of grooves are located on a first surface of the metal part. Organic material parts of the first connection plate member are located in the plurality of grooves, and are fixedly connected to the metal part. The first buffer member is located between the first metal plate member and the second metal plate member. The first buffer member is stacked on the first surface of the metal part, and is fixedly connected to the organic material parts. When the display module is applied to an electronic device, the electronic device is easily folded and has sufficient support strength.
