Cover Lens Manufacturer
Custom Strengthened Glass Cover Lenses
In addition to providing custom LCD, OLED and capacitive touchscreen products, we are a glass cover lens supplier, licensed by Corning Incorporated to process Corning® Gorilla® Glass for cover lens applications. Our fully-equipped glass factories in China can manufacture custom cover lenses to meet the appearance and functionality requirements of your project. Whether you need custom flat or 3D shapes, screen printing, specialized films and coatings, or other value-added services – we can provide a unique solution for your project. And, if you’re in the market for custom display and touch components as well, we can manufacture and integrate those along with your custom cover lens so you don’t have to shop around multiple suppliers. This can mean huge development time and cost savings for your project. Whether you’re looking for a cover lens, display, touch sensor or a combination of all three, our expert sales and technical teams across the globe are ready to support you throughout all design, manufacturing and logistics stages.

Common Treatments for Cover Lenses
This type of treatment involves applying a film or coating of a specific thickness to the surface of a cover lens. The film reduces the reflections on the surface by canceling out a specific wavelength of light as it is reflected back to the consumer. When a specific wavelength of light passes through the AR material, some of it is reflected back to the consumer at the surface of the AR film (R1) and some of it is reflected at the surface of the cover lens (R2). The thickness of the AR film causes the reflected wavelengths (R1, R2) to be reflected exactly out of phase with each other (see diagram 1.1) so that they cancel each other out. Thus the consumer will not see their own reflection. Instead, they will see a brighter and more vivid display.
This type of treatment involves creating a rough surface on the cover lens via an etching process. As light reflects off of the rough surface, it is scattered at different angles (see diagram 1.2) which reduces the clarity of the reflected image. Thus, the consumer will not see the bright glare of any reflected light source.
AF/AS (Anti-Finger Print/Anti-Smudge)
This type of treatment reduces the ability of the cover lens retaining oils from your finger. AF/AS treatment is typically applied by vacuum deposition or by a liquid chemistry process, which creates an oleophobic top coating. Since this layer is a chemical modification of the glass surface, it is very durable compared to aftermarket AF/AS spray-on films and it is very thin with little or no impact on the optical quality of the display.
It has to be noted that AF/AS treatments do not perfectly prevent fingerprints. They only cause finger oils to bead on the surface, which makes them less noticeable and also much easier to clean off the screen.
Another benefit of the AF/AS coating is the “feel” or user perception of the treated surface. Because the surface is smooth, the finger will glide more easily compared to a non-treated surface. A non-treated cover lens surface can cause the user’s finger to stick, skip, feel like it’s being dragged, or even make drawing a singular line on the screen difficult so that it becomes a dotted line.
