Information

Cover Glass Design & Integration Service

Advanced solutions for optimizing E Ink display performance in demanding environments

At Good Display, we specialize in engineering premium cover glass solutions that enhance durability, optical clarity, and functionality of E Ink displays across all applications.

Why Cover Glass Matters for E Ink Displays

Optimizing E Ink display performance in challenging environments requires careful consideration of cover glass design and integration. The cover glass serves as a crucial shield against scratches and impacts, while also enhancing optical clarity and enabling touchscreen capabilities.

High-quality cover glass integration can increase display lifespan by up to 300% while maintaining optimal optical performance with >92% light transmission and <1.5% haze levels.

Enhanced Protection

Resists scratches, impacts, and environmental hazards with chemically strengthened glass

Optical Clarity

Maintains >92% light transmission with anti-reflective and anti-glare treatments

Touch Integration

Enables seamless integration of capacitive touch technology

Easy Maintenance

Worn surfaces can be restored with simple top film replacement

Cover Glass Selection Guide

Our comprehensive selection of cover glass substrates is engineered for optimal performance in diverse applications. We help you select the perfect solution based on your specific requirements.

Material Options

Asahi Glass

Known for exceptional stability and impact resistance, Asahi Glass undergoes a proprietary chemical strengthening process that creates deep compression layers (>40μm) for superior durability.

Best for: Automotive applications, industrial equipment, outdoor displays where thermal cycling and impact resistance are critical.

Corning Glass

With higher surface hardness (up to 7H pencil hardness) and exceptional scratch resistance, Corning Glass features advanced ion-exchange technology for superior surface compression.

Best for: High-traffic consumer devices, retail displays, medical equipment requiring frequent cleaning.

PMMA (Polymer Alternative)

An economical alternative with good optical properties and impact resistance. PMMA offers weight reduction (up to 50% lighter than glass) and superior shatter resistance.

Best for: Cost-sensitive applications, lightweight devices, environments where shatter-resistance is paramount.

Value-Added Integration Options

Enhance your E Ink display with advanced integration options that extend functionality and longevity.

Touch Screen Integration

Seamlessly integrate projected capacitive (PCAP) touch technology with optimized cover glass solutions. Our bonding process ensures perfect optical alignment and eliminates Newton rings.

Front-Light Systems

Integrate uniform edge-lit illumination with <2% brightness variance across the display surface. Our optical waveguide technology ensures zero hotspot performance.

Optical Bonding

Our OCA (Optically Clear Adhesive) bonding eliminates air gaps, reducing reflection by up to 75% while enhancing impact resistance and optical clarity.

Easy Replacement System

When normal wear occurs, our unique top film replacement system allows restoration without full assembly replacement. Simply replace the protective top film for like-new performance.

Advanced Bonding Techniques

The cover glass is attached to the E Ink display using either specialized tape or optically clear adhesive (OCA).

OCA Bonding Process

Our OCA bonding process creates a permanent, optically perfect bond between layers:

0.125-0.2mm (0.005"-0.008") adhesive thickness
Applied as a uniform sheet for complete surface coverage
Lamination under controlled vacuum environment
UV or thermal curing for optimal bond strength

Compared to traditional tape bonding, OCA bonding eliminates air gaps, reduces reflection, and enhances impact resistance by up to 40% while maintaining display clarity.

Our proprietary OCA formulation maintains optical clarity with >99% transmission and <0.5% haze even after 1000 thermal cycles from -30°C to 85°C.
