You don't need to be an environmental scientist to make sustainable choices.
At Good Display, we passionately integrate sustainability into the production of e-paper.

 

 

 

 

 

 

Substitute for Paper Usage

Epaper provide a paper-like touch and reading experience, serving as a sustainable alternative to traditional paper and reducing environmental impact from deforestation and paper manufacturing.

Device Packaging
95% of this device's packaging is crafted from wood fiber-based materials sourced responsibly from managed forests or recycled sources.

Energy Efficiency
Epaper consumes minimal energy compared to conventional displays, reducing electricity bills and easing the demand on power plants, thereby lowering greenhouse gas emissions—a perfect choice for eco-conscious consumers.
