Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with slide-out flexible displays face challenges in accommodating a display driving circuit within limited space without interfering with the sliding operation of the flexible display.
Innovation Solution
The electronic device incorporates a flexible display with a first and second curved part, a bendable section, and a display driving circuit positioned in the second section, which is disposed between the sliding plate and the second section, allowing for easy placement without obstructing the sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid substrate is used to ensure structural stability, then manufacturing precision and reliability are improved, but flexibility and formability are worsened
Solution Approach 1:
The substrate is divided into multiple flexible substrates stacked together, where each substrate maintains structural integrity while allowing relative movement between layers. This segmentation enables the overall structure to be both stable (through the stacked configuration) and flexible (through layer movement).
Solution Approach 2:
The patent uses composite material structures combining flexible substrates with transparent conductive films and functional layers. This composite construction provides both the structural stability needed for reliability and the flexibility required for formability, as each material layer contributes specific properties that work together.
2Adaptability or versatility
If the display module is made foldable or rollable to enhance adaptability, then formability and portability are improved, but structural stability and manufacturing precision are worsened
Solution Approach 1:
By segmenting the display into multiple flexible substrates that can move relative to each other, the structure achieves formability through layer movement while maintaining manufacturing precision through the controlled stacking and alignment of these segments. The segmentation allows the display to be manufactured with precise alignment that is maintained during folding or rolling operations.
3Illumination intensity
If transparent conductive films are applied to enhance display quality, then optical properties are improved, but device complexity and manufacturing difficulty are worsened
Solution Approach 1:
The transparent conductive films are merged with the flexible substrate structure, where the films are applied directly to the substrate surfaces as an integral part of the display assembly. This merging approach improves optical properties while reducing manufacturing complexity by eliminating separate, complex assembly steps for the conductive films.
