Description:
The all-in-one LED display device adopts the split design of the screen and system, with highly integrated functions; it has the characteristics of long service lifespan, fast frame changing speed, high refresh rate, good uniformity, wide viewing angle, high grayscale, etc. It is widely used in lecture theatre, academic lecture halls, conference rooms in colleges and universities, and various display occasions.
Feature:
* Adopt no “lower forehead” design and ultra-narrow frame, with screen ratio of up to 99%, beautiful and elegant. The aluminum alloy frame adopts anti-collision rounded corner design for safer using.
* With ultra-wide viewing angle, the screen has a large viewing range, and the picture is still clear when viewed from any angle. High refresh rate, good picture continuity and high fluency.
* Using bottomless design, the module is attached to the cabinet, which can evenly conduct the heat generated by the lamp beads, effectively reducing heat radiation, and proving better immersive visual experience. No fan structure, the noise of the whole machine is ≤10dB.
* Built-in dead pixel elimination algorithm, it can automatically identify failed lamp beads, and eliminate all caterpillar phenomenon caused by open circuit.
* The software is developed and customized based on the Android system. It has writing, browsing, sharing, and collaboration four functions. The operation is smooth and the application scenarios are rich. Built-in WPS, clock, welcome interface, calendar and other application software, and third-party APP applications can be added.
* Built-in hidden antenna (WIFI, AP, Bluetooth), can realize Wi-Fi wireless Internet connection and AP wireless hotspot transmission at the same time. Support bluetooth 4.0, can connect Bluetooth remote control, Bluetooth mouse, Bluetooth keyboard, Bluetooth speaker and other peripherals.
* For different conference application scenarios, it provides 4 scene modes: standard, soft, cinema, and video; you can customize and adjust the brightness, saturation, and contrast, so that document presentation, video playback, and remote conferences can all achieve the best display effect.
* Support one key to turn on the eye comfort mode to improve the viewing comfort, reduce the damage of high-energy blue light, and protect the eyes.
* Support ultra-low power consumption mode. After enabled, the machine will enter a deep sleep state, and the power consumption is as low as 0.6W.
* Support wireless screen projection function, the external computer screen can be transmitted to the large screen through screen projection software or screen projection device, and up to four devices can be projected at the same time. Support Windows, Mac OS, iOS, and Android system.
* Support wireless counter control function. Users can reversely control the display screen through Android tablet/mobile phone, and the counter-control device and the display screen are displayed synchronously and interactively, providing more vivid and simple writing interaction of reports, presentation, discussions and other scenes.
* Support wireless speech function, users can speak through Android tablet/mobile phone, and the sound can be transmitted to the professional sound system of the large screen.
* Support infrared remote control and Bluetooth function, and operations such as power on and off, signal source and scene mode switching can be performed remotely through the remote control.
* Support preset high-definition base image. When the network cable is disconnected or there is no video source signal input, the preset image can be displayed to ensure that the screen is seamlessly connected.
* Three optional installation methods: wall mounted, floor stand and hoisting.
