Display Glass Substrates

£1,570.00

Our high-precision Display Glass Substrates deliver exceptional thermal stability, ultralow total pitch variation, and defect-free surfaces engineered for advanced LCD, OLED, and foldable display manufacturing. Produced using fusion-draw technology, these substrates support Gen 8.5+ production lines while meeting stringent semiconductor-grade cleanliness standards for high-resolution mobile, automotive, and large-format panels.

Competitive Advantage Spotlight
Unlike conventional substrates that compromise on warpage or particle control at scale, our non-alkali glass achieves >20% higher strain point and near-zero birefringence, enabling thinner designs without breakage. Backed by just-in-time global logistics and ISO 9001:2024 certified supply chain traceability, we reduce your secondary processing rejects by up to 35% compared to incumbent suppliers.

Description

Product Overview
Display Glass Substrates are high-purity, alkali-free boro-aluminosilicate glass sheets engineered for thin-film transistor (TFT) backplane fabrication. They serve as the foundational layer for LCD, OLED, and micro-LED displays, enabling superior resolution, brightness uniformity, and thermal durability during high-temperature processing. By minimizing warpage and particle defects, they directly increase panel production yields—a critical profitability lever in high-volume fabs. Their strategic importance lies in enabling advanced display form factors (foldable, rollable, 8K+) while reducing material breakage in Gen 10.5+ fabrication lines.

Key Specifications & Technical Characteristics

Chemical composition: Alkali-free boro-aluminosilicate (SiO₂, B₂O₃, Al₂O₃, alkaline earth oxides)
Purity level: ≥99.99% trace metal basis; ≤0.1 ppm mobile ions (Na⁺, K⁺)
Physical characteristics: Sheet form; thickness range 0.2mm – 1.1mm ±0.01mm; Gen 6 to Gen 10.5 mother glass sizes; strain point >650°C; CTE 3.2 ppm/°C (20–300°C)
Packaging options: Epoxy-coated interleaving paper; cleanroom-sealed cassettes (20–50 sheets/cassette); vacuum-sealed custom crates for sea freight
Shelf life: 24 months when stored in controlled environment (20–25°C, <40% RH, original packaging unopened)

Core Industrial Applications

Primary industries: Consumer electronics displays (smartphones, tablets, TVs), automotive instrument clusters, medical diagnostic monitors, aerospace cockpit displays.
Operational use cases: TFT backplane deposition (a-Si, LTPS, IGZO), color filter substrate lamination, foldable cover glass for UTG (ultra-thin glass) lamination.
Performance advantage: Lower thermal shrinkage (<10 ppm vs. standard 30–50 ppm) ensures mask alignment accuracy for 8K/4K photolithography. Higher Young’s modulus (75 GPa) reduces breakage during robotic handling, cutting scrap rates by 18–25% in Gen 10.5 fabs.
Efficiency/cost advantage: Alkali-free composition eliminates ion migration, increasing panel luminance lifespan by 30% and reducing warranty claims.

Competitive Advantages

Quality consistency: <0.5% coefficient of variation in thickness and bow within each master sheet lot; in-line AOI (automated optical inspection) with 2μm defect detection.
Supply reliability: Dual sourcing from two ISO 14001:2021-certified plants; 99.5% on-time delivery record for 24-month frame agreements.
Logistics capability: Anti-static, humidity-controlled packaging; flat-rack or specialized glass-container loading with shock loggers.
Price competitiveness: 12–15% lower total landed cost versus leading Japanese and German alternatives for Gen 8.5+ formats.
Sustainability: 35% post-industrial recycled cullet content; fully recyclable interleaving material; REACH and RoHS compliant.
Technical support: DFM (Design for Manufacturability) review prior to first shipment; on-site commissioning support at customer cleanroom.

Commercial & Supply Information

Minimum order quantity (MOQ): BULK 20MT (approx. 550–700 sheets of Gen 10.5, depending on thickness)
