Cover Glass For Touch Screen

Custom Cover Glass For Touch Screen Applications

We manufacture custom cover glass for touch screen applications used in consumer electronics, industrial HMIs, automotive displays, control panels and other electronic devices. Our touch screen cover glass can be customized according to customer drawings, including glass size, thickness, shape, edge finishing, holes, cutouts and printed borders.

Available processing options include chemical strengthening, thermal tempering, CNC machining, silk screen printing, AR (anti-reflective), AG (anti-glare) and AF (anti-fingerprint) surface treatments. We can also provide bonding and lamination solutions according to the display structure and assembly requirements.

For OEM projects, customers can specify the glass material, dimensions, optical requirements, surface treatment and estimated quantity. Our engineering team can review the drawing and recommend a suitable glass processing solution before production.

Chemical Strengthened Touch Screen Cover Glass

Chemical strengthening is commonly used for thin touch screen cover glass where surface strength, scratch resistance and durability are important. The ion-exchange process creates a compressive stress layer on the glass surface. Strengthening parameters such as compressive stress (CS) and depth of layer (DOL) can be inspected according to project requirements.

Cover Glass for Touch Screen Raw Material

In Weiman, we source famous brands substrates including AGC glass, dragon tail glass, Panda glass, Gorilla glass.

To most of the oversea customers, we fully understand they only know about Gorilla Glass or Dragon Tail.

In this case, some suppliers may shift to other aluminosilicate glass due to cost, but strengthening parameters(CS / DOL) tell difference.

Each shipment, we offer inspection report including these testing data to remove your worries.

CNC Machining for Touch Screen Cover Glass

• Precision cutting
• CNC grinding
• Edge polishing
• Drilling
• Slots
• Notches
• 2D / 2.5D / 3D shapes
• Custom dimensions

Cover Glass for Touch Screen Tempering Process

The glass tempering methods including chemical strengthening & thermally tempered as mentioned above, but do you know differences between them and in house or not? Let me tell you:

✔Chemical strengthening, it uses ion exchange principle larger sodium ions replace by smaller potassium ions in molten salt generating compressive stress layer on surface against cracks and impact.

Why I said different in house or 3rd party? It’s because the cost(time, around 6H) for strengthening process is quite high, some suppliers may shorten the time to save cost but hardness reduced.

In Weiman, we will offer inspection report including CS / DOL to tell you the test result of strengthening result which can’t be seemed by eye.

✔Themerlly tempering, it uses high temperature( around 600 celsius) + strong wind blow to change the glass structure, which makes the glass 5-6 times stronger than normal glass.

If you met problem suppliers, they may use half tempering intead of full tempering due to cheaper, the glass became harder but not the safety glass.

In Weiman, we offer test report of particle test / IK test to verify the glass safety and hardness.

So all process done in house, we could offer you stable tempering result instead of batch differences.

Silk Screen Printing for Touch Screen Cover Glass

• Black border
• White printing
• Logos
• Icons
• Custom patterns
• Printing alignment
• Ink adhesion
• Appearance inspection

Cover Glass for Touch Screen Coatings

In cover glass, there are usually refers to 3 kinds of coating: AR(Anti reflection), AG(Anti glare) and AF(Anti fingerprint), also called 3A in glass processing industry.

Below picture tells the differences.

✔To AR, there are different optical requirements which makes the coating green tone or purple tone.

✔To AG, there are 3 kinds of treatments including AG film, acid etching and printing, different method have different cost.

✔To AF, there are 2 kinds of treatments including plating(higher cost but durable) and spray(cheaper but less durable).

If you don’t know differences in every kinds of coatings, you will pay high prices but poor quality. More importantly, it can destroy whole products.

So every process is quite important, all processes done in house can guarantee the quality / batch stability.

Touch Screen Cover Glass Quality Inspection

Each production batch can be inspected according to the agreed quality requirements. Inspection may include dimensional accuracy, appearance, edge condition, printing quality, coating performance and strengthening parameters where applicable.

Applications of Cover Glass For Touch Screen

Frequently Asked Questions

What is cover glass for a touch screen?

Cover glass for a touch screen is the outer glass layer that protects the display and touch module from scratches, impact and daily wear while maintaining optical clarity and touch functionality.

What materials can be used for touch screen cover glass?

Depending on the application, available materials may include aluminosilicate glass, soda-lime glass and other specialty glass options. Material selection depends on thickness, strength, optical requirements and application conditions.

Can you manufacture custom cover glass for touch screen according to drawings?

Yes. Custom dimensions, shapes, holes, slots, edge finishing, printed borders and other processing requirements can be manufactured according to customer drawings and technical specifications.

Can touch screen cover glass be chemically strengthened?

Yes. Chemical strengthening is commonly used for thin cover glass to improve surface strength and resistance to scratches and impact. Strengthening parameters can be specified and inspected according to project requirements.

Can you add AR, AG and AF coatings to touch screen cover glass?

Yes. AR, AG and AF treatments can be evaluated individually or in selected combinations according to the optical, surface and application requirements of the touchscreen.
