Custom Tempered Cover Lens for Display Windows
Custom Tempered Cover Lens for Display Windows
A tempered cover lens is the finished glass window installed in front of an electronic display to protect the screen while maintaining clear visual performance and reliable operation.
We manufacture custom tempered cover lenses according to your drawing, display dimensions and assembly requirements. Depending on the application, the glass can be supplied with CNC-cut openings, drilled holes, polished edges, silk-screen graphics and AR, AG or AF surface treatments.
Rather than offering one standard lens size, we process each cover lens around the requirements of the final device. This makes the solution suitable for industrial displays, HMI equipment, control panels, POS terminals, household appliances and other electronic interfaces.
Designed Around Your Display
The tempered cover lens can be customized for:
- Rectangular, square, round and irregular display windows
- Touchscreen and non-touchscreen displays
- Flat, 2.5D and selected 3D edge designs
- Mounting holes, slots and cut-outs
- Black borders and functional silk-screen printing
- Different glass thicknesses and substrate options
- AR, AG and AF surface treatments
- Adhesive bonding or OCA lamination requirements

Production Capabilities
In Weiman, we offer tempered cover lens customization fabrication services including:
Cutting: Rough shapes by diamond unit or laser cutting from big sheet of glass substrate into rough shapes of the final products, but edge is still sharp and big tolerances.
CNC processings:Edge grinding and chamfering, slotting, hole drilling.
Tempering: Chemically strengthening for thickness under 3.0mm and thermally tempering for 3.0mm thickness above.
Silk screen print: For thin thickness cover glass option, we use resin ink for print and for thermal tempering we use 3.0mm thickness above.
AR means anti reflection by electroplating base on different spectral bands, single side increase 3-4% light transittance and double sides up to 99% at most.
AF with 2 kinds of methods including electroplating(costly but more durable) and spray(cheaper but less durable), it can also protect the AR coating from easy peel off.
AG means anti glare, usually under acid etching way to prevent glare under ambient light or sun light to glass.
Bonding: Mainly focus on 3M tapes including adhesive transfer tape, VHB tape and OCA tapes.
Lamination: Foil to protect from dirt and explosion proof sheet for better anti scatter.

Glass Options for Different Applications:

The right substrate depends on the required strength, optical performance, thickness and project budget.
Soda-lime glass
A cost-effective option for applications where standard optical performance and mechanical protection are sufficient.
Aluminosilicate glass
Suitable for applications requiring higher surface strength, better scratch resistance and a thinner cover lens design.
Branded strengthened glass
Gorilla Glass, Panda Glass and other specified substrates can be processed according to project requirements.
Tempering Method
The strengthening process is selected according to the glass thickness, dimensions and performance requirements.
For thin electronic cover lenses, chemical strengthening can improve surface strength while maintaining good dimensional stability and optical flatness.
For thicker glass applications, thermal tempering can be considered when higher mechanical strength and safety characteristics are required.
Our engineering team can recommend the appropriate strengthening route after reviewing the glass specification and application.
Precision Processing Before Delivery
A tempered cover lens is more than a piece of strengthened glass. The finished component may require several secondary processes before it can be assembled into your product.
Available processing includes:
- CNC cutting and profiling
- Hole drilling and slotting
- Edge grinding and polishing
- Chamfering
- Silk-screen printing
- AR coating
- AG treatment
- AF / oleophobic coating
- Adhesive application
- OCA lamination
- Protective film application
- Quality inspection
All dimensions and processing requirements can be produced according to your CAD drawing or technical specification.
Typical Applications
Tempered cover lenses are commonly used as protective display windows in:
- Industrial HMI displays
- Automation control panels
- POS terminals
- Smart home control interfaces
- Household appliances
- Medical and instrumentation displays
- Automotive and transportation interfaces
- Commercial electronic equipment
The final glass specification should be selected according to the display size, touch technology, installation method and operating environment.

Why Specify a Custom Tempered Cover Lens?
For display manufacturers, the cover lens often has to match several components at the same time — the display module, touchscreen, housing and mounting structure.
A small dimensional error, unsuitable edge treatment or incorrect coating can affect final assembly.
That is why we manufacture the lens from the customer’s drawing and application requirements rather than treating it as a standard glass panel.
FAQ
What is a tempered cover lens?
A tempered cover lens is a customized glass component installed over an electronic display. It provides mechanical protection while allowing the display to remain visible and usable.
Can the tempered cover lens be made to my drawing?
Yes. We can manufacture the lens according to CAD drawings, dimensions, hole positions, edge requirements and other technical specifications.
Can you add printing to the cover lens?
Yes. Silk-screen printing can be used for borders, logos, icons, markings and other functional graphics.
Can tempered cover lenses have AR, AG or AF treatment?
Yes. AR, AG and AF treatments can be selected according to the optical and environmental requirements of the application.
What glass should I choose for a tempered cover lens?
It depends on thickness, required strength, optical performance and cost. Soda-lime and aluminosilicate are common choices, while specified branded glass can also be processed for certain projects.
Can you produce samples before mass production?
Yes. Prototype samples can be produced to verify dimensions, appearance, processing and assembly before moving to mass production.
