TAICENN TPC-PC121A series is a low power-consumption, Fan-less designed, enhanced stability and reliability industrial 12.1-inch Touch Panel PC product. It adapts Intel Apollo lake J3455/J3355 processor. TPC-PC121A series storage can support 2.5'' SATA and mSATA interface, HDD or SSD. The design uses a multi-point (10- points) projective capacitive touch screen (Optional with high-temp. five-wires resistive touch, or no touch), and it can fulfill front panel NEMA/IP65 dust-proof and water-proof standards.
The TPC-PC121A uses full-sealed box construction, and it can prevent dust from entering the device system.
The TAICENN TPC-PC121A is compatible with Win10, Linux OS, and it also has a good compatibility with customized applications and software programs.
There are two types of overlay based touch screens:
● Capacitive Touch Technology – Capacitive touch screens take advantage of the conductivity of the object to detect location of touch. While they are durable and last for a long time, they can malfunction if they get wet. Their performance is also compromised if a non-conductor like a gloved finger presses on the screen. Most smart phones and tablets have capacitive touch screens.
● Resistive Touch Technology – Resistive touch screens have moving parts. There is an air gap between two layers of transparent material. When the user applies pressure to the outer layer, it touches the inner layer at specific locations. An electric circuit is completed and the location can be determined. Though they are cheaper to build compared to capacitive touch screens, they are also less sensitive and can wear out quickly.
