Description:

LED display device with a split screen and system design, with highly integrated functions, supports ultra-fast 10-point touch, and has the characteristics of long service life, fast frame change speed, high refresh rate, good uniformity, wide viewing angle, high grayscale, etc. It is suitable for university tiered classrooms, academic lecture halls, large, medium and small university conference rooms and other places.

Features:

* The whole machine adopts an ultra-narrow frame, and the aluminum alloy frame adopts an anti-collision rounded corner design, with seamless connections at the corners, making the product and people safer.

* The module inside the screen has a bottomless design. The module fits the box, and the lamp beads dissipate heat quickly and evenly, effectively reducing heat radiation. Users will not feel "burned", and the immersive visual experience is better. There is no fan structure, and the noise of the whole machine is ≤10dB.

* The software is developed and customized based on the Android system, with three major functions: browsing, sharing, and collaboration, and rich application scenarios. It has built-in WPS, clock, welcome interface, calendar and other application software, and can add third-party APP applications.

* It has built-in hidden antennas (WIFI, AP, Bluetooth), which can realize Wi-Fi wireless Internet access and AP wireless hotspot transmission at the same time. It has Bluetooth 5.0 and can connect to common peripherals such as Bluetooth remote control, Bluetooth mouse, Bluetooth keyboard, Bluetooth speakers, etc.

* It has a one-button eye protection mode. When it is turned on, it can effectively reduce the damage of harmful high-energy blue light, improve the comfort of viewing, and protect the eyes.

* It has a preset high-definition background map. When the network cable is disconnected or there is no video source signal input, the preset picture can be displayed to ensure that there is no black screen and the picture is seamlessly connected.

* The LED display screen adopts a "jawless" design, with a screen-to-body ratio of 96.8%.

* The LED display unit module and the unit box use an industrial-grade precision floating wireless connector, which has the ability to correct the deviation, and the connection is more stable. The whole screen seam can be finely adjusted in units of modules to avoid the light and dark line effect between modules due to the seam. The signal cable and low-voltage power cable cannot be seen inside the box, and it can be directly plugged in and out with power.

* The LED display switch power supply has a PFC function, a power factor of 0.95, a power efficiency of ≥91%@25℃, and has over-current, short-circuit, over-voltage, and under-voltage protection functions; it eliminates the phenomenon of flashing and black screen caused by unstable power grid.

* The LED display has a 32768*32768-point driver-free touch function, and can support 10-point multi-person barrier-free touch writing at the same time, and can write on any opaque touch object such as fingers/brushes. The touch accuracy is 1mm, the touch recognition size is 2.5mm, the single-point touch response time is ≤9ms, and the light resistance is ≥80000Lux.

* The LED display screen can be adjusted in multiple levels of brightness from 0 to 100% through the remote control or mouse sliding menu.

* The entire LED display screen can be powered by a single power cord, which can be powered by AC power. It has distributed power supply measures and does not require special preparation of other power supply accessories such as power boxes and distribution cabinets.

* The PCB of the LED display module adopts surface immersion gold treatment, with a board thickness of ≥2.0mm, a copper thickness of ≥1 ounce, and a TG of ≥150℃.

* The LED display screen uses Type-C to replace traditional network cables for signal transmission, and uses 5G high-bandwidth and low-latency transmission technology. A single Type-C can carry 2.6 MP data.

* The LED display screen has a one-button low-power mode, which retains the user's current process and enters a deep sleep state. In low-power mode, the power consumption of the entire machine is ≤0.6W.

* The LED display screen has infrared remote control sleep/wake-up and low-power functions, and the effective distance of infrared remote control startup is 5m. At the same time, the remote control has the functions of page turning, signal source selection switching, brightness, and volume control. The menu key has the function of opening the system and application menus, and the direction keys have the functions of operating menus and options up, down, left, and right.

* The LED display screen has 4 scene modes: standard, soft, cinema, and video. At the same time, the brightness, saturation, contrast and other parameters can be customized. Users can choose different modes for different conference application scenarios to ensure that large-screen document presentations, video playback, and remote conferences can all present excellent display effects.

* The LED display screen has Windows, MacOS, iOS, and Android multi-platform terminals that connect to the display screen hotspot for 4-screen wireless projection. The Windows PC terminal needs to use a hardware wireless projection device.

* The LED display screen has 2.4G and 5G dual-band WIFI access. The built-in WIFI6 transmitter module can quickly create 2.4G and 5G dual-band wireless hotspots to connect and interact with third-party devices. When third-party devices are connected and interacted, they will not interfere with the main screen network. The wireless unobstructed effective use distance can reach 8m.

* Optional wall brackets, floor brackets, hanging brackets and other installation methods.
