Features:
- 800×800 Square Resolution — Equal horizontal and vertical pixel count. Ideal for round-bezel meter displays, instrument panels, and square embedded screens.
- 80/80/80/80° Wide Viewing Angle — Consistent image quality from any position. Clear readability for operators viewing instruments at various angles.
- 7H Hard Coating Surface — Exceptionally scratch-resistant 7H hardness — harder than most smartphone screen protectors. Protects against keys, tools, and sharp objects in industrial meter and instrument environments. Extends panel service life significantly.
- PCAP Capacitive Touch — Projected capacitive touch for smooth, responsive multi-finger interaction. Suitable for gloved operation in industrial environments. No additional touch overlay needed.
