Capacitive Touchscreens

Surprisingly, capacitive touchscreens were the earlier form of touchscreen technology. Capacitive screens are made up of one or more layers of coated material that is shielded from the outside by a protective cover. The coating on the surface of the layers is normally a conductor, typically Indium Tin Oxide. This conductive surface allows another electrical conductor, such as a finger or stylus, to complete the circuit when touching the surface, thus enabling embedded sensors to detect the touch event

1) Aluminum alloy frame, surface sandblasting and anodic oxidation treatment, iron shell back cover, active heat dissipation;
2) 4mm physical tempered anti-riot glass; enhance the visual effect and enhance the touch experience;
3) High-speed 10-point touch writing experience, better smoothness and faster writing speed;
5) Using the OPS slot of the international general standard, the integrated plug-in design is convenient for upgrading and maintenance, and there is no visible external connection line of the computer module, and the body is beautiful;
6) Front expansion port: 1 PC-USB, 1 full-channel-USB, including 1 HDMI input on the lower side of the front, 1 TOUCH USB, 1 TYPE-C (USB2.0 protocol), which is convenient for users to connect external devices use
7) The speaker is placed in front of the sound to prevent the sound effect from deteriorating due to the embedded environment;
8) Child lock function, the button function can be shielded by setting;
9) Support gestures to pull up the menu, the menu can quickly adjust the brightness and sound, and switch the signal source
10) The front button is one-key start, which can turn on and off the screen and the host at the same time, and the operation is simple and convenient
11) Android 8.0 system support, multi-theme system setting switch at any time, startup LOGO setting customization and other functions
12) The system comes with functions such as screen projection, electronic whiteboard, and annotation
13) The screen assembly process adopts zero bonding technology, so that the display screen is naturally clear and transparent
