Industrial operating temperature range
COG (Chip on glass)

Displays with Chip on Glass characterize with smaller thickness of all outer dimensions and thanks to more hermetic construction they are tighter and more shock-resistant. Additionally, they are more price-attractive and have lower power consumption.
Inbuilt voltage generator

Apart from controller’s logic voltage supply, to obtain a suitable contrast the display requires an additional voltage. Thanks to an inbuilt voltage generator, there is no need to supply the display with outer voltage.
