Description:


Employing a high-strength cabinet, its precise streamlined structure achieves an ultra-thin and flat profile, showcasing a minimalist yet modern industrial aesthetic. The delicate surface treatment gives it a low-key, elegant matte texture, seamlessly integrating into various high-end spaces. The custom-designed cabinet not only protects internal components from dust but also maintains a clean and uncluttered rear view. Featuring seamless display, perfect display quality, long lifespan, fast frame rate, high refresh rate, excellent uniformity, wide viewing angle, high grayscale, and natural color reproduction, it is widely used in command and dispatch, security monitoring, video conferencing, broadcasting, and various indoor conference room displays.



Features:



* Can be used for real-time monitoring of on-site conditions and playback of various promotional advertisements.

* Seamless splicing with no visual black seams.

* Flexible and compact display units, suitable for flat and curved surfaces, allowing for smooth splicing.

* DC low-voltage power supply, natural heat dissipation, fanless operation, zero noise.

* Ultra-low out-of-box failure rate, extremely low maintenance and operating costs, and easy unit board replacement.

* Supports image correction, employing gamma correction technology for point-by-point brightness and color correction.

* Supports intelligent light control, intelligently adjusting brightness to improve viewing comfort and save energy.

* Ultra-wide viewing angle, providing a wider viewing range and clear images from any angle.

* High refresh rate, ensuring smooth and consistent image quality.

* Delicate and realistic images, maintaining excellent grayscale even in low brightness conditions.

* Supports ultra-high-definition display, employing unique image enhancement technology to effectively improve image clarity and deliver smooth, ghosting-free high-speed images.

* The LED display module adopts a plastic-free base shell design. The die-cast aluminum cabinet is in direct contact with the PCB, and the direct contact between the PCB edges and the four sides of the die-cast cabinet improves thermal conductivity. Compared with products with plastic base shells, this better solves the problems of color drift and reduced lifespan caused by heat dissipation.

* The LED display adopts a non-contact magnetic levitation front maintenance design, allowing for front-side disassembly of modules, adapter boards, and other low-voltage components. Multiple hot-swap tests ensure normal operation.

* The LED display's color temperature is continuously adjustable from 1000K to 20000K, with multiple white level adjustments including cool, warm, and standard. At a color temperature of 8500K, the color temperature error for the four white level adjustments (100%, 75%, 50%, and 25%) is ≤100K.

* The LED display screen records the number of times it is turned on and off and its usage duration, with a data retention period of 100 days. It also supports monitoring of on-site temperature and humidity, displaying the data in real-time on the control software, allowing users to easily understand the on-site screen and ambient temperature and humidity data.

* The LED display screen has a FLASH intelligent storage circuit that can store module calibration data. Replacing a module automatically retrieves the calibration data, with a storage capacity of ≥1MB.

* The LED display screen features a low blue light mode, with three adjustable blue light output levels (30%, 40%, and 70%) selectable in the control software, effectively reducing the harmful effects of blue light radiation on the eyes.
