Detail Information
Automotive sapphire display cover glass is a precision-machined, optical-grade single crystal sapphire panel used as the outer protective surface of a vehicle central control touch display. With Mohs 9 hardness, it is selected when hard interior parts, service tools, rings, keys, or repeated cleaning can cause cosmetic damage or functional screen failure on conventional cover materials. Felix Glass supports drawing-based C-plane sapphire covers in 0.6 mm, 0.8 mm, and 1.0 mm standard thickness options, with custom CNC edges, holes, AR anti-reflection coating, and AF anti-fingerprint coating for automotive equipment manufacturers. The material choice is most valuable where long service life, optical stability, and resistance to hard-contact scratches matter more than lowest initial part cost. Optical-grade single crystal material provides a consistent protective window for high-resolution center displays when the crystal orientation, polish, and coating are correctly specified. The specified -40℃ to 120℃ continuous range supports programs that must tolerate vehicle storage, operation, and temperature cycling conditions. AF coating reduces fingerprint adhesion and simplifies routine cleaning; AR coating helps manage surface reflection in bright cabin conditions. These values define the requested product baseline. Final inspection methods, sampling plan, coating targets, and acceptance limits are documented on the approved project specification. Felix Glass reviews 2D and 3D files for outer-profile machining, corner radii, chamfers, steps, slots, through-holes, sensor openings, and non-standard cutouts. Engineering feedback focuses on manufacturability and the risk of concentrated stress around thin edges and internal features. The AR layer is engineered around the display spectrum, viewing angle, and reflection target. The AF top layer is selected for touch interaction, cleanability, and compatibility with the underlying AR stack. Coating performance must be confirmed using project-specific optical and durability criteria rather than a generic transmission claim. Target wavelength band, incident angle, reflectance goal, display stack, and coating side. Contact-angle target, cleaning agent, abrasion method, touch frequency, and acceptance limit. A project test report should identify the sample configuration, coating lot, fixture, temperature profile, dwell time, ramp rate, cycle count, inspection method, and acceptance criteria. The requested -40℃ to 120℃ range is the product baseline; it is not presented as a completed program-specific test result until the agreed test plan has been executed. Thickness selection should be made with the active display area, unsupported span, adhesive geometry, edge protection, touch performance, impact requirement, and assembly load in view. The requested 20-10 scratch & dig grade applies to the defined optical area and must be paired with an agreed inspection method, illumination, viewing distance, cosmetic zones, edge criteria, and coating-defect limits. Separate acceptance zones can be established for the active display area, printed border, adhesive region, holes, and finished edges. Lead time is confirmed after drawing, quantity, raw-material availability, CNC complexity, coating route, inspection documentation, and packaging requirements are reviewed. The project follows a controlled progression so procurement and engineering teams can freeze risks before volume release. Crystal orientation affects material and processing behavior. C-plane optical-grade sapphire is the requested baseline, but final orientation and inspection requirements should remain explicit on the drawing and purchase specification. Yes, subject to DFM review. Hole diameter, edge distance, corner radius, chamfer, thickness, and assembly load influence manufacturability and breakage risk. Yes. The plan should add reflectance or transmission criteria, coating appearance zones, adhesion or abrasion methods, cleanability, and any contact-angle requirement. No. It is the requested continuous working range. Program qualification requires an approved profile, sample configuration, cycle count, inspection criteria, and documented results. Provide the 2D or 3D drawing, annual and order quantities, thickness, coating targets, cosmetic zones, validation requirements, packaging standard, and required delivery location. Drawing-based sample and volume planning are supported. Capacity, yield assumptions, inspection documentation, and schedule are confirmed after the technical review. Automotive optical engineers and equipment procurement managers can send drawings and project requirements to james@felixglass.com. Include the display stack, annual volume, coating target, temperature profile, cosmetic criteria, and assembly method for a focused manufacturability review.
