Product Overview
What Is Display Cover Glass Used For?
Display cover glass is commonly selected when a display system requires a balanced combination of scratch resistance, optical transmission, mechanical durability, printing compatibility and long-term environmental stability. Felix Glass manufactures customized cover glass for medical diagnostic equipment, industrial control panels, wearable devices, household appliances, outdoor monitoring terminals and compact automotive display assemblies.
Core substrateHigh-strength aluminosilicate glass for medical and industrial grade cover lenses.
Alternative materialsSoda-lime glass for cost-sensitive designs and borosilicate glass for heat or chemical resistance.
Typical use logicChoose by touch frequency, impact requirement, coating target, shape complexity and assembly tolerance.

Design Guidelines
Engineering Design Points for Custom Display Cover Glass
Stable cover glass projects usually start with drawing review, edge safety, sensor window planning, coating zone definition and assembly tolerance confirmation before prototype production.
Edge and hole designUse suitable chamfer radius, keep hole-to-edge distance stable, and reduce micro-crack risk before strengthening.
Printing and sensor windowsReserve border tolerance, camera windows, IR zones and zero-printing areas according to assembly stack.
Optical bonding readinessControl flatness, cleanliness, bonding border width and visual area transmission consistency.
Curved transition controlFor 2.5D and 3D structures, transition smoothness and coating feasibility should be evaluated together.

FAQ
Frequently Asked Questions About Display Cover Glass
What is the difference between aluminosilicate and soda-lime display glass?
Aluminosilicate glass provides higher hardness, stronger chemical strengthening response and better long-term touch fatigue resistance for industrial and medical usage.
Can display cover glass support optical bonding?
Yes. Flatness, warpage and surface cleanliness can be controlled for full lamination and optical bonding requirements.
Can logos or borders be silk printed?
Yes. Black, white and custom ceramic ink printing can be applied for durable borders, icons, windows and brand marks.
Can the cover glass reach IK impact resistance grades?
IK07 to IK10 targets can be evaluated by adjusting thickness, strengthening depth, edge processing and structure design.
What is the minimum customizable thickness?
Ultra-thin display glass from 0.3 mm can be manufactured for wearable and portable device applications.
Can anti-bacterial coating be applied?
Medical-grade anti-bacterial coating is available for hospital diagnostic, nursing and healthcare display equipment.
Do you support prototype orders?
Prototype production can be arranged for drawing verification, optical testing, assembly trial and later batch production planning.
Which drawing formats are accepted?
DWG, DXF, PDF, STEP and common engineering drawing formats can be reviewed for customization.
