Glass technology guides, application notes and industry knowledge from JZJ Glass engineers
Anti-reflective (AR) coating reduces surface reflections from ~8% to below 0.5% per surface, dramatically improving display visibility in bright environments. This article explains the physics of AR interference coatings, single-layer vs multi-layer approaches, and how to specify AR glass for outdoor displays, marine navigation and industrial HMIs.
Anti-glare (AG) glass uses micro-etched or coated surfaces to scatter reflected light, eliminating mirror-like reflections. This guide covers gloss units (GU), haze percentage, Ra surface roughness, sparkline (anti-sparkle) requirements, and how to balance AG level with display resolution for readable outdoor digital signage.
Chemically strengthened glass achieves up to 8x the strength of annealed glass through K+-Na+ ion exchange. This article explains the ion exchange process, compressive depth (DOL), surface stress (CS), drop ball testing, modulus of rupture, and how chemical tempering compares to thermal tempering for thin display cover glass.
CNC mechanical cutting and laser cutting each offer advantages for display glass fabrication. This comparison covers edge quality (chipping, micro-cracks), cutting speed, thickness range, complex shape capability, cost factors, and how to choose the right cutting method for your optical glass project.
Marine displays face unique challenges: salt spray corrosion, extreme temperature variations, high vibration, direct sunlight, and strict class society requirements. This article covers IEC 60945 and IACS UR E10 compliance, salt fog testing, brightness requirements (1000+ nits), dimming range, and ECDIS/Radar display glass specifications.
Surface quality directly impacts display performance and user perception. This guide explains MIL-PRF-13830B scratch-dig standards (80/50, 60/40, 40/20, 20/10), how scratch-dig is measured visually and by instrument, acceptable defect sizes for display cover glass, and how JZJ Glass controls surface quality through inspection protocols.
