Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rollable display devices experience static electricity generation due to friction between layers when rolled, leading to potential damage from electrostatic discharge.
Innovation Solution
Incorporating a discharger between the overlapping portions of the rollable display panel to reduce friction and provide a path for static electricity release, thereby minimizing static electricity accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rollable display panel is rolled, then the display device achieves compact storage and portability, but static electricity is generated due to friction between layers
Solution Approach 1:
A discharger component is introduced as an intermediary between the first and second portions of the rollable display panel. This discharger provides a dedicated electrical conduction path that mediates the charge transfer during rolling, allowing static electricity to be safely discharged through the discharger rather than accumulating through friction between panel layers.
Solution Approach 2:
The harmful static electricity generation process is effectively separated from the rolling mechanism by extracting the charge discharge function into a dedicated discharger component. This allows the rolling operation to maintain its portability function while the discharger independently handles the static electricity problem.
2Object-generated harmful factors
If the discharger is positioned between the first portion and the second portion during rolling, then static electricity is reduced, but the device structure becomes more complex
Solution Approach 1:
The discharger is integrated with the rollable display panel structure, merging the static electricity discharge function into the existing panel architecture. This combination approach allows the discharger to be positioned between panel portions during rolling without requiring entirely separate structural components, thereby reducing overall device complexity.
3Object-generated harmful factors
If friction between layers is reduced, then static electricity generation is minimized, but the mechanical bonding between layers may be weakened
Solution Approach 1:
The discharger serves as an intermediary electrical conduction path that addresses static electricity without requiring changes to the mechanical bonding between layers. By providing a dedicated charge transfer route, the discharger allows the layer interfaces to maintain their original mechanical strength while eliminating the need to reduce friction for static electricity prevention.

AI summary
A display device includes a rollable display panel and a discharger. The rollable display panel with a first portion and a second portion includes a displaying side and a non-displaying side opposite to the displaying side. The discharger is disposed on one of the displaying side and the non-displaying side, wherein the discharger is positioned between the first portion and the second portion when the rollable display panel is rolled and the first portion and the second portion move close to each other.
