Product Description
The 7 inch capacitive touch screen panel, support operation with gloves, water , and working well with 10mm thick tempered glass or thick PC on top of the cover glass, mainly used in medical, industrial, security, home appliances and other fields. Deep custom service available.
This 7-inch capacitive touch screen module belongs to the standard module launched by our company. The display resolution is 1024*600, LVDS interface, industrial wide temperature, It has excellent anti-interference performance. It can support some special functions; the display screen is TN panel material. If the customer has actual needs, it can be directly replaced with a display screen of IPS panel material. The capacitive touch screen and the display screen can also be directly optical bonded.

Technical Q&A
Q: Is there any suggestion regarding the capacitive touch screen module solutoin directly used by raspberry pi and orange pi?
A: We have some mature projects cases and the best way is to connect the touch screen directly through USB interface to the Raspberry Pi or the orange Pi, and the display can be directly connected through HDMI interface, this way the whole solution can be implemented through plug and play. Large size touch screen will be designed directly with USB interface, small size is general designed with IIC interface, so we will do is to provide the board which changes the IIC into USB. however, customers need to contact our technicians to check the configuration and software system. For display, we can provide RGB to HDMI, LVDS to HDMI, MPI to HDMI, EDP to HDMI and other driver boards to realize the connection with Raspberry Pi and orange pi;
Q: According to the investigation, you company have done a lot of actual cases of pure industrial applications. Can you give some design suggestions to our customers in the industrial application field?
A: The environment of industrial application will be relatively complex, such as the interference of power grid environment and servo motor, so the anti-jamming performance of touch IC itself must be considered when choosing capacitive touch screen solution in the early stage, otherwise, in the actual batch application, there will be a variety of errors like, touchscreen chaotic jump, or wrong touch. We must pay attention to the design of protection circuit in the process of motherboard design. If possible, the shell, touch screen and the motherboard should finally connect to one GND. Of course, we will also consider the anti-interference design solution in the design process of the touch sensor and FPC. For specific details, you can communicate with our professional technicians according to the actual case.
