Frequently Asked Questions
An Open Frame Touch Panel PC is a industrial-grade computing device with a touchscreen display designed without an external housing or chassis, allowing it to be integrated directly into custom enclosures, kiosks, or control panels. These systems feature a slim profile with mounting brackets around the edges for easy installation, and are ideal for applications in industrial automation, kiosks, digital signage, and control systems.
Open Frame Panel PCs offer easier integration into custom enclosures, flexible mounting options, space savings with slim profiles, customizable front bezels to match application aesthetics, often lower cost due to simplified construction, and adaptability for specialized environments. They maintain the ruggedness and reliability of industrial Panel PCs while providing more installation versatility.
Open Frame Panel PCs typically offer multiple mounting options including panel/cutout mounting using the brackets around the frame's periphery, VESA mounting patterns (75mm x 75mm or 100mm x 100mm) for attachment to arms or stands, and custom mounting solutions through pre-drilled mounting holes. The open frame design specifically facilitates flush integration into custom enclosures, control panels, and kiosk systems.
Resistive touchscreens detect pressure and can be operated with gloves, styluses, or any object, making them ideal for industrial environments where operators may wear gloves. Capacitive touchscreens offer superior clarity, multi-touch capability, and durability but require a conductive input (like a bare finger). OFT models offer both options to suit different application needs and environmental conditions.
OFT Panel PCs are designed with front bezels that can achieve IP65 protection rating when properly installed in an enclosure, protecting against dust and water splashes from the front. The open frame design allows system integrators to incorporate the panel into custom enclosures that can provide additional environmental protection appropriate for the specific installation environment.
The OFR-21WMX features a 21.5" Full HD (1920x1080) display, projected capacitive multi-touch screen, industrial-grade panel with 350 cd/m² brightness, wide viewing angles (178°/178°), versatile video inputs including HDMI, VGA, and DisplayPort, wide voltage input (12-24V DC), and an open frame design with multiple mounting options for integration into custom enclosures.
Unlike OFT series Panel PCs that include integrated computing systems, the OFR-21WMX is a touchscreen monitor without built-in processing capabilities. It connects to external computing systems via standard video interfaces (HDMI, VGA, DisplayPort), offers the same industrial-grade construction and mounting options, but allows flexibility to pair with any computing platform, upgrade computing hardware independently, and reduce costs when only display functionality is needed.
The OFR-21WMX provides exceptional flexibility through multiple video inputs compatible with various computing devices, standard USB touch interface working with most operating systems, open frame design for custom enclosure integration, VESA mounting compatibility for standard mounting solutions, and a separate power input allowing centralized or distributed power management in complex installations with multiple displays.
Open frame design refers to a display or Panel PC constructed without an external housing or chassis, featuring only a front bezel with mounting brackets. This design offers advantages including flexible integration into custom enclosures, kiosks, or control panels; reduced depth and weight compared to fully enclosed systems; ability to achieve a flush, seamless appearance in the final installation; and customization options for specialized industrial or commercial applications.
Resistive touchscreens detect physical pressure, work with any input device (gloved fingers, styluses), offer good durability against chemicals and harsh environments, but provide less clarity and no multi-touch. Projected capacitive (PCAP) touchscreens detect electrical properties of the human body, offer superior optical clarity, multi-touch capability, and better durability against surface scratches, but typically require a bare finger or conductive stylus.
OFT and OFR series achieve environmental protection through front bezels designed to meet IP65 standards when properly installed in an enclosure. This is accomplished using specialized gaskets and seals around the display perimeter, watertight mounting brackets, sealed touchscreen-to-bezel bonding, and proper installation techniques. While the rear remains open by design, the front protection prevents dust and water ingress from the exposed face of the installation.
Wide voltage input (typically 9-36V DC or 12-24V DC) allows OFT Panel PCs to operate reliably with various power sources and in environments with fluctuating power conditions. This flexibility accommodates different industrial power standards, handles voltage drops in long cable runs, provides tolerance against surges or sags, and eliminates the need for additional power conditioning equipment in challenging industrial settings.
Important mounting considerations include securing all mounting brackets evenly to prevent display distortion or stress, maintaining proper clearance for cooling, ensuring the mounting surface can support the weight, applying the correct torque to mounting hardware, installing appropriate gaskets for environmental protection, planning for cable management, and considering accessibility for maintenance while maintaining the specified IP protection rating at the front surface.
Open frame Panel PCs typically support several mounting methods: panel mount/cutout installation where the device is inserted into a cabinet cutout and secured with mounting brackets; VESA mount using standard 75x75mm or 100x100mm patterns; direct mounting to a flat surface using the pre-drilled holes on the chassis; and custom mounting solutions for specialized applications like kiosks or machine integration, each requiring specific considerations for proper support and environmental protection.
Best practices for cabling include: planning cable routes to prevent stress on connectors, using appropriate cable ties or management systems to secure cables without pinching, implementing strain relief to prevent tension on connections, maintaining minimum bend radius for each cable type, keeping power cables separate from signal cables to prevent interference, using appropriate length cables to avoid excess loops, and ensuring all connections are secure and protected from physical damage or environmental exposure.
Cutout dimensions for panel mounting must follow manufacturer specifications exactly, typically allowing for a 1-2mm tolerance. Important considerations include measuring the active display area plus bezel (not just the screen), accounting for mounting brackets and their clearance needs, ensuring sufficient depth behind the panel for cables and connectors, verifying the panel material is strong enough to support the device weight, and planning for proper sealing to maintain environmental ratings.
To optimize touch functionality: ensure the touch controller cable is properly connected, install correct touch drivers for the operating system, run calibration utilities after installation, avoid mounting near sources of electrical interference, ensure the mounting implementation doesn't put pressure on the display edges which could affect touch accuracy, and test touch functionality across the entire screen before finalizing installation to confirm proper operation throughout.
For touch issues: ensure the touch cable is properly connected internally, check for physical damage to the screen surface, verify touch drivers are properly installed and updated, run the operating system's touch calibration utility, check for sources of electrical interference near the device, ensure no mounting pressure is affecting the display edges, test with another application to isolate software-specific issues, and for persistent problems, contact technical support.
For display issues: verify the power source is within specified voltage range, check all video connections are secure, confirm the input source is working with another display if possible, verify the correct input is selected via OSD controls, adjust brightness settings if the image is very dim, check for physical damage to cables or connectors, and test with different resolution settings as some displays have optimal resolution requirements for proper image reproduction.
For overheating: verify the ambient temperature is within specified operating range, ensure adequate clearance around the unit for passive cooling, check that mounting hasn't restricted heat dissipation from the rear, avoid installation near other heat-generating equipment, consider adding auxiliary cooling for installations in high-temperature environments, check resource-intensive applications that may be causing high CPU usage, and verify the device firmware and drivers are updated to the latest versions.
If the unit won't power on: check power supply connections and verify output voltage is correct, inspect power cables for damage, verify internal power connections are secure if recently serviced, check for LED indicators that might signal power presence, try an alternative power supply meeting the specified requirements, reset the device by disconnecting power for 30 seconds, and if possible, connect a known working display to the same power source to determine if the power supply is functioning correctly.
