Product Description for B&R 5PC720.1706-00 Color TFT Display Assembly

This integrated color display assembly is the original factory visual core exclusively matched to B&R 5PC720.1706-00 zero-PCI-slot 17-inch Panel PC 720 all-in-one control unit. The full assembly consists of industrial 17-inch SXGA color TFT liquid crystal panel, CCFL backlight drive module, four-wire resistive touch digitizer, hardened front protective glass, sealed mounting frame and isolated signal drive circuit boards. Every internal component undergoes strict brightness aging testing, touch coordinate calibration, shock and vibration screening, and conformal coating treatment before final assembly and factory shipment. Designed for round-the-clock heavy industrial continuous operation, the whole unit resists dust, humid air, workshop corrosive vapors, mechanical vibration and strong electromagnetic interference generated by on-site motors, inverters and high-voltage switchgear. Adopting modular split structure, the display subsystem can be independently disassembled, repaired or replaced without removing the entire Panel PC host, greatly simplifying field maintenance workflows. After full installation and frame sealing, the front panel reaches IP65 ingress protection grade to block liquid splashes, grinding dust and particulate contaminants from damaging internal optical and electronic components.

The color display assembly is tailor-sized and electrically calibrated for the 5PC720.1706-00 Panel PC chassis within B&R Panel PC 700 product platform, with no cross-compatibility with other screen size Panel PC models. The core display medium is a 17-inch 4:3 aspect ratio industrial color TFT panel with native SXGA resolution specification, bonded with analog resistive touch layer behind the front tempered protective glass. The backlight system applies stable cold cathode fluorescent lamp drive architecture with independent isolated power regulation circuits separated from the mainboard power rail to avoid voltage fluctuation affecting screen brightness uniformity. All internal signal and power wiring uses locked plug-in connectors for firm electrical connection to the Panel PC motherboard, eliminating loose contact risks under long-term equipment vibration. The complete display subsystem complies with CE industrial safety, EMC and RoHS environmental standards, produced under B&R ISO 9001 full lifecycle quality management system with traceable component batches, pre-set factory brightness, contrast and touch linearity parameters. It serves as a standardized spare replacement assembly for faults such as screen yellowing, backlight burnout, touch coordinate drift and front glass abrasion. The rear drive circuit area holds IP20 protection rating to prevent accidental contact with live terminals during inspection and maintenance operations.

The core functional positioning delivers high-clarity real-time visualization of automation operation data and intuitive touch-based operator interaction for on-site process and machinery control. The SXGA color TFT screen renders rich graphical HMI interfaces including real-time process numerical readings, trend curves, equipment status icons, production recipe editing pages, safety interlock prompt windows and system fault alarm outputs executed by the embedded Windows CE runtime and PLC logic. The integrated resistive touch digitizer converts physical pressing force into precise digital coordinate signals transmitted to the host CPU, enabling direct hands-on operation for parameter adjustment, running mode switching, page navigation and safety confirmation without external mouse or keyboard peripherals. The built-in backlight drive circuit supports software adjustable brightness levels via B&R Automation Studio platform; operators can dim brightness to reduce power consumption or boost luminance for high-brightness workshop environments exposed to strong natural light. Real-time monitoring circuits continuously feed back backlight operating state and touch circuit health data to the mainboard; abnormal conditions like backlight failure, touch open-circuit or short-circuit will trigger system log records and local buzzer fault reminders. The hardened front glass provides scratch resistance and physical impact shielding for the fragile liquid crystal layer, while the sealed frame structure stops dust and moisture infiltration to sustain long-term stable optical display performance. The display assembly maintains steady signal transmission and consistent color output even when the host runs full-load HMI display and communication tasks simultaneously.

The 17-inch color TFT panel features native SXGA resolution of 1280 × 1024 pixels, supporting up to 16.7 million display colors with industrial balanced color gamut and uniform brightness distribution across the full active screen area. The four-wire resistive touch panel supports stable operation with gloved hands, delivering over one million valid mechanical press cycles of service durability before measurable performance decline. Standard touch activation force ranges from 20 grams to 80 grams, with response time lower than 10 milliseconds and linearity error controlled below 1.5 percent for accurate coordinate positioning. The CCFL backlight unit provides a rated brightness of 250 cd/m², with a half-brightness service life of 50,000 continuous operating hours under 25°C ambient temperature. The entire display assembly runs stably within the Panel PC working temperature range of -20°C to +60°C; spare display modules can be safely stored between -40°C and +70°C during transportation and warehouse stocking. Touch signal circuits feature ultra-low coordinate drift under drastic temperature swings and sustained mechanical vibration, with factory calibration data stored in non-volatile memory on the drive printed circuit board. Surge suppression and EMI filter components are integrated onto display driver boards to prevent screen flicker, color distortion or touch misoperation caused by surrounding electromagnetic noise. The front protective glass reaches 3H pencil hardness grade for enhanced anti-abrasion capability. Low-voltage differential signal transmission channels connect the display module to the motherboard to minimize internal signal attenuation inside the sealed chassis. Internal drive circuits include overvoltage, overcurrent and short-circuit protection to shield optical components from power grid surge damage. Horizontal viewing angle reaches 75 degrees left and right, vertical viewing angle 75 degrees upward and 60 degrees downward for multi-operator viewing flexibility.

Compatible original supporting accessories include replacement resistive touch overlay digitizer sheets for worn touch surfaces, spare CCFL backlight tubes and matching inverter drive boards for backlight fault maintenance. Disposable transparent anti-scratch protective films shield the front glass surface from daily abrasion and chemical residue accumulation. Frame sealing gaskets are supplied to restore full IP65 water and dust tightness after disassembly and reassembly during repair procedures. Official B&R Automation Studio software integrates dedicated tools for touch coordinate recalibration, backlight brightness tuning and post-repair display system health status verification. Specialized disassembly fastener tools prevent chassis and frame deformation during screen removal and reinstallation. Spare internal signal and power wiring harness plugs act as wear-part replacements for aged or damaged electrical connectors. Anti-reflection upgrade films can be attached to the front glass for installation sites exposed to intense sunlight or high-brightness workshop lighting. Shock-absorbing foam padding kits stabilize the display assembly inside the Panel PC chassis for ultra-high-vibration working environments such as metal forging and heavy machining production lines. Standard terminal insulation sleeves and cable strain relief fittings stop wiring loosening induced by long-duration equipment vibration.
