Wide-Temperature E-Paper Display Characteristics
Designed for Extreme Environments, but Content Adaptation is Required |
||
|
This product utilizes wide-temperature e-paper technology, enabling stable operation in indoor environments ranging from -25°C to 50°C（-4°F to 122°F）. However, due to the physical properties of e-paper, high-density dynamic graphics (such as scatter plots and line charts) may not appear as clear as on standard e-paper displays.
|
||
|
Recommended Applications: Best suited for static text, simple icons, data tables, barcodes, and other high-contrast, low-refresh-rate content.

Why Scatter Plot Sucks
E-Ink displays rely on microcapsule charge flipping to render content. With low refresh rates and limited grayscale levels, high-density scatter plots can appear grainy, especially at 30-50°C（86-122°F）. To enhance visibility, consider simplifying the graphics or emphasizing key data points.

Disclaimer：
Due to the characteristics of e-ink technology, complex graphics may have display limitations. Please ensure it meets your specific usage needs before purchasing. For technical support or customized solutions, please contact customer service.
