Huddle rooms and public touch displays face high daily wear, scratches, and constant finger friction. The 4.0mm heavy-duty tempered glass shields the costly underlying 4K IPS panel from damage. Simultaneously, its anti-glare treatment diffuses harsh overhead office light patterns, ensuring texts and numbers remain sharp and highly readable.
