Advanced Electronic Cover Glass: Next-Generation Protection for High-Tech Displays

Today’s premium electronic devices demand advance electronic cover glass that does more than just protect – it enhances performance. Advanced electronic cover glass serves as the crucial interface between users and their devices, combining:

Military-grade protection against drops and scratches

Optical clarity rivaling bare displays

Advanced functionality like anti-microbial properties

From smartphones to automotive displays, the right advanced electronic cover glass solution can mean the difference between a good device and a great one.

In Weiman, we offer fully in house production including cutting, CNC processing(Grinding, Drilling, Slot), Silkscreen print(Low temperature ink and high temperature ink), tempering(chemical strengthening and thermal tempering), coatings(anti reflection, anti glare, anti fingerprint), bonding(3M tape, OCA tape) and lamination(PE film, exposion proof sheet).

Only with this way, we can guarantee uniform quality in each unit and each batch.

For advanced electronic cover glass, chemical strengthened is the most regular way because the glass substrate normally in thin thickness(Less than 3mm), the chemical strengthened can have excellent hardness(especially aluminosilicate glass 7-8H, gorilla glass up to 9H) , flatness and optical performance. So this strengthening method widely used in consumer electronics, medical devices and other indoor applications.

So what’s chemical strengthened? It’s a kind of chemical reaction with ion exchange, below picture can tell more clearly:
