HMIs: Open frame panel PCs for industrial applications
An increasing number of OEMs require ready-to-mount flat-panel display subsystems as the interface in applications such as test instrumentation, medical devices, and machine control. A Panel PC handles

WinSystems’ RoHS compliant panel PC consists of a color TFT flat-panel display, Pentium-class single board computer (SBC), and touchscreen mounted in an open aluminum frame. The open frame chassis provides a variety of mounting options. The back of the panel PC is designed for easy access and connection to I/O and power cables, while the unit supports standard operating systems such as WindowsXPe and Linux, plus x86-based real-time executives, utilities, and drivers.
“The genesis of this product is from multiple requests from our customers to provide an operator interface packaged as a system component,” says Bob Burckle, WinSystems vice president. “A panel PC puts all the pieces together in a compact, rugged form for use as a display subsystem for factory automation or industrial instrumentation.”
WinSystems currently offers three sizes of displays : 6.5, 12, and 15 in. The displays are from Optrex, which provide crisp image quality on a thin flat screen with minimal distortion. Each provides high luminance, a wide viewing angle, and excellent contrast ratio to ensure color fidelity and superior gray scaling. Resolutions vary by screen size from 640 x 480 VGA for a small 6.5 in. unit, to 1024 x 768 XGA for a 15 in. unit. An anti-reflective coating has been applied to reduce surface reflectivity to make them easier to read in high ambient light environments.
