Cover Glass: Do you know
Cover glass, also called as cover lens, screen protector, glass lens etc., which used as a guard on outermost layer for touch screen. The cover glass raw material mostly by ultra thin flat glass with brands like Gorilla glass, Dragon Tail, AGC, Panda and other domestic brands. Under cutting, CNC grinding/drilling, strengthening, silk print, coatings, tapes etc. to make your design come true.
Then the cover glass play the role for screen in outermost layer to resist impact, anti scratch, repel oil, anti fingerprint, improve transmittance and other properties.
Cover glass is the keep up appearance of screen when first sight customer see the product, it’s not only the guard for screen but also support different printing design like different colors, patterns and logos to enhance product’s aesthetics. Since touch era arrived and spearheaded by Apple, which established capacitive touch solutions and the industry benchmark for mobile device interaction. The stable performance and premium user experience made them ubiquitous in smartphones, tablets and touchscreen laptops. Irrespective of the underlying touch technology, the cover glass continues to be a vital safeguard.
Compare with alternative materials, cover glass provides pronounced advantages in hardness, impact resistance, anti scratch, thickness and surface advantages to establish themselves as the predominance protective solution in touchscreen industry today. Also the rapid proliferation of 5G networks in recent years imposed increasingly stringent material requirements on electronic devices. Metal casings, which tend to interfere with signal transmission, have become less viable for 5G-compatible devices, prompting many smartphone manufacturers to adopt non-metallic cover materials to mitigate signal attenuation. Moreover, the unique circumstances of 2020 drove a dramatic surge in online education, remote work, and telemedicine, which in turn fueled skyrocketing demand for large-screen tablets. Consequently, the cover glass market experienced robust growth during this period.
What’s the application of cover glass?
The cover glass are keeping increase in apply various industries including automobiles, electronic product, smart watches / wearable devices, appliance, medical device, industrial machine and other outdoor applications like vendor machines.
The advantage for selecting cover glass.
The advantage for selecting cover glass.
1.High optical tranparency:
Delivers exceptional clarity, ensuring the display content remains sharp and vividly visible.
3.Multi surface treatments:
Offers a range of special coatings including anti fingerprint, anti reflective and anti glare treatments to improve user experience.
2.Excellent hardness & scratch resistance:
Significantly harder than most alternative materials, which offer robust protection against everyday scratches and abrasion.
4.Resistance to heat and chemical:
The glass is a guard to resist lots of chemicals and remains stable under high temperatures.
5.No discoloration over time:
Compared to plastics and other materials, glass does not discolor or yellow over long periods of use and exposure to sunlight.
7.Smooth touch:
Glass offers a smoother, more natural touch experience than some plastics and other cover materials.
6.Better sensitive touch sensing:
Specific glass types and coatings can improve the responsiveness and precision touch screens.
8.Upscale and aesthetically pleasing:
Cover glass provides an upscale and modern look in device.
In summary, the cover glass combines high transparency, exceptional durability, superior optical performance, and refined aesthetics makes glass the preferred choice for a broad spectrum of touchscreen and display applications.
Cover Glass Manufacturing Process & Principles
To produce a piece of cover glass raw material, it mainly through 2 methods: Overflow downdraw process and the float glass process. The first one dominates the industry nowaday which offer high yields, superior quality and better overall performance. The second one is valued for its exceptional flatness and optical properties.
Regardless of the initial method, additional downstream process is essential to meet functional demands. The full production cycle from raw material to final coating and packaging, details below:
- Cutting: Base on CAD file, it’s the first step to cut raw glass material to dimensions slightly larger than final product use precision automatic cutting machines.
- CNC:After cutting, the edge is still rough and sharp, the CNC offer nicely and different edge options, polish and 2.5D edge, which form the outline of the glass specification, meanwhile it offers hole drilling service.
- Tempering(Chemically strengthened): The purpose is to increase surface compressive stress to enhance scratch and impact resistance. This process involves immersing the glass in a potassium(KNO₃) solution at approximately 400°C facilitating ion exchange between sodium ions (Na⁺) on the glass surface and potassium ions (K⁺) in this As potassium ions are larger than sodium ions, their replacement creates a compressive stress layer on the glass surface, delivering the desired strengthening effect.
- Silk Screen Printing
Silk Screen printing apply various colors, shapes and patterns to the glass surface. This is accomplished through screen printing and drying techniques to adhere ink to the glass, meeting specific design requirements. - Coating
The purpose of coating is to deposit functional layers at designated locations on the glass surface. This is performed under vacuum conditions using electron beam evaporation or magnetron sputtering to apply film materials. Common coatings include anti-fingerprint (AF) and anti-reflective (AR) films.Meanwhile, anti glare(AG) treatment use acid etching / spray methods. - Cleaning
Cleaning is essential to remove dirt, smudgesand particulate contaminants from the glass surface using ultrasonic cleaning systems. This step ensures optimal results in subsequent tempering, screen printing, and coating processes.
