An open frame touchscreen is a display without a finished consumer bezel, made to be built into a machine or kiosk. The evidenced model on this site, the ZTMC0, offers capacitive or infrared touch across 10 to 32 inch sizes with 1920 by 1080 resolution and a metal case. The touch choice is the first decision for most buyers of this model, because it decides how the operator interacts with the machine.
Capacitive touch works like a phone screen: it responds to a bare finger with a smooth, precise feel, and it suits clean indoor machines where the operator's hands are bare. Infrared touch works by breaking light beams across the screen surface, so it responds to a finger, a gloved hand or a stylus, and it suits industrial posts, outdoor kiosks and situations where gloves are worn.
The trade-offs are durability and feel. A capacitive front glass can be made flush and easy to clean, while an infrared frame tolerates a wider range of inputs but adds a frame around the viewing area. A buyer should describe the operator, the gloves if any, and the cleaning regime in an enquiry so the company can confirm the touch type for the size and enclosure.
