Ultra-High Brightness Open Frame Display, 2500 nits Sunlight Readable LCDs with 110℃ High Tni LC, Wide Working Temperature for Outdoor Use, EVSE HMI Solution
Key Features
- 2500cd/m² (up to 3000cd/m²) typical brightness combined with Full HD resolution will capture the attention of the audience in bright environments
- Wide operating temperature range from -20℃ to +70℃
- Direct LED backlighting offers superior brightness, extended runtimes and advanced engineering necessary for digital signage and messaging in high ambient light applications.
- Ultra Resistant to Blackening Defect (up to 110°C). This is crucial for outward-facing window displays, which must contend with exposure to direct sunlight.
- Designed and developed for continuous 24/7 operation
- External Light Sensor automatically adjusts the brightness level
- Embedded Modular design (LCD Panel + LED Driving Board + AD Control Board + Power Board), ideally for embed usage for semi-outdoor and outdoor environment.
- Installation Methods: Chassis integration or rear mount
Open Frame Designs for Effortless Integration, Endless Applications
Designs for Effortless Integration, Endless Applications
The WF-MH series open frame displays are built to stand out in different outdoor environments with 2,500 – 3000 nits of ultra-high brightness. The LED-backlit open frame panels include brightness levels that maximise visibility, along with an energy-saving Light Sensor that make the ultra-high brightness digital signage display ideal for 24/7 outdoor use. An open-frame option boosts adaptability, allowing for easier integration into customized designs. In contrast, wide working temperature feature design coupled with a light sensor keeps temperatures in control, enhancing the WF-MH series display’s aptitude for outdoor use.
Three (3) Product Formats are optional:
- OPT.1: LCD Monitor with HDMI IN, VGA IN, DVI IN
- OPT.2: AIO Android screen, integrated with Android player
- OPT.3: AIO Windows OS screen, integrated with X86 Board with Windows OS

2500 NITS ULTRA-HIGH BRIGHTNESS
WF-MH series High Brightness Open Frame products are available in a variety of sizes and can handle up to 2500 nits brightness, making them ideal for use in bright conditions. These High Brightness Open Frame products are excellent for indoor and outdoor applications such as self-service kiosks, charging stations, smart poles, displays for industrial automation, and more, thanks to their adjustable mounting, orientation, and diverse connectivity features.
24/7 OPERATION UNDER SUNLIGHT
The WF-MH series is made of a Public Information Display (PID) panel for 24/7 operation, in which the liquid crystal cell can resist heat up to 110°C / 230°F, compared to the typical TV panel, around 65-75°C (149-167°F). This unique high-temperature liquid crystal technology prevents the black spots that can develop on competing displays when subject to high heat loads from direct sunlight.
LOW REFLECTION FOR SUPERIOR READABILITY
The WF-MH series displays adopt the Quarter Wave Plate (QWP) polariser with a low reflection solution to enhance the visibility and colour vibrancy of the display for outdoor applications.
AN EASY-TO-MOVE SENSOR BOARD FOR IR & LIGHT
The IR light and ambient light sensor board can be easy-to-move and easy to be fixed to suit different outdoor environments.
LANDSCAPE/PORTRAIT CAPABILITY
The WF-MH series displays are signage-friendly and can perfectly fit either in a landscape or in a portrait mode to experience complete screen orientation flexibility and fullfil the need in different scenarios.
