Capacitive touch screen has been increasingly used in various fields with rapid technology development. In order to meet different requirements of worldwide customers, Grahowlet supply all kinds of product structures such as G + G, G + F (G + F + F ),P + G, etc. and various technical support programs such as Cypress , Atmel, EETI, FocalTech, Goodix etc. according to different application environments.
Cover glass surface treatment--AG, AR, AF
Anti Glare (AG) processing could eliminate screen surface mirror problem through converting
direct light to diffuse light on the touch screen.
AF processing is adding on the cover glass a king of coating that could increases surface smoothness,
reduces surface sliding resistance , residual water and fingerprints
on the surface significantly and improves feeling and clarity.
Technical Q & A
Q: Can you tell us about your company's main products, process and size range?
A: Our main products include: special glass cover, capacitive touch screen, LCD screen, capacitive touch screen module, supporting driving board;
Technical process: G+G structure, P+G structure and GFF structure, including flexible touch screen,
Bonding process: Air bonding & Optical bonding.
Size range from 1.3 inch to 65 inch, and there are no projects in batch production with size above 65 inch at the moment.
Q:According to our understanding, the amount of products used in industrial projects is generally not very large, and the project cycle is longer. How do you deal with this?
A: If you can ask such a question, it shows that you still have a certain understanding of the field of industrial capacitive screens, and the actual situation is indeed like this.
In view of the long lead time, we have special personnel to do the project training, and we will take into account the project cycle length and life cycle in the design of the pre-project. the recommended solution are basically industrial, which generally can ensure that the solution can be sustained in 3-5 years of mass production supply. even if one of the material shutdown, we also have alternative schemes for customers, which will not affect the structure of customer’s end products. The most we do is to help customers fine-tune some software without affecting the hardware part.
For the quantity issue, we have a complete system for customers in the industrial field. Generally, after the sample test is passed, we will add another small batch of trial production opportunities, during this time, the quantity is not limited, and just need to meet MOQ requirement after this. Actually we don’t have high MOQ requirements for industrial customers in combination with production and materials investment, the specific MOQ is related to sizes of the screen. Please contact our sales for more details.
