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: What are the precautions for the application of capacitive touch screen made of PMMA cover?
A: As for the cover of capacitive touch screen made by PMMA material, we must consider the material of sensor, the impact of high and low-temperature shock and warpage. As for the specific details, we have some mature application cases. Customers can contact our technicians for detailed solutions and parameters according to the actual needs of specific products.
Q: Many industrial customers used resistive touch screens or untouched ones before, for the upgrade of projects, they may be the first time to deal with capacitive screens and don't have much understanding of the adjustment and functional application of capacitive screens, how did you serve this kind of customers in the early stage?
A: There are some customers who have just get involved in the capacitive screen products. In view of this situation, we usually cooperate in two situations:
First, if the project schedule is rather tense, we usually provide drive-free solutions directly. We can convert the IIC interface of the capacitive screen into the USB interface for direct application, we can also convert the display screen into the various interfaces like VGA or HDMI for direct application so that customers can save early time in early stage of development;
Second, if the project schedule is relatively abundant, we usually provide professional debugging data to the customer technicians, and then the specialized technicians in our company wil assist the customer in technical debugging. We have a professional technical team to do a good job of technical services in this area.
