HMI Touch Display
HMI stands for “human-machine interface” and includes a HMI display and usually also a touch panel. The display of an HMI visualizes process parameters or status modules of equipment for the user or the service technician. With the touch panel, entries can also be made directly on the HMI modules.
Even the module of an MP-3 player, together with individual buttons, could already be used as an operating unit or HMI. So there are also small HMI modules, with ELECTRONIC ASSEMBLY from 2 ”screen. These classified ads are completely sufficient for many applications of smaller devices (HMI example EA uniTFTs020 with 2 “incl. PCAP touch panel).
Essential for an easy-to-use HMI is a brilliant, bright display (possibly as an IPS) and fast, highly integrated intelligence. This enables intuitive user interfaces, which users are happy to accept.
