The QDE QD-E8143062 is an 86-inch interactive display designed to serve as a collaborative hub for professional or educational environments. It features a 4K resolution screen with 3840*2160 pixels and a D-LED backlight that provides 450 nits of brightness, ensuring that content remains clear and visible across a wide 178-degree viewing angle. To make long sessions more comfortable, the surface is protected by anti-glare glass, which reduces reflections from overhead lighting. Under the hood, the system runs on a RK3576 processor with a combination of Cortex-A72 and A53 cores, supported by 8GB of RAM and 128GB of internal storage. This hardware allows for smooth multitasking within the Android operating system. Interaction is handled by an infrared touch frame that supports 40 simultaneous touch points with a precision of ±1mm, allowing multiple people to write or draw on the screen at once with a natural writing height of less than 1.5mm. Connectivity is extensive, with a front panel featuring HDMI and Type-C inputs along with three USB 3.0 ports for quick access to peripherals. The rear offers further expansion through RS232, RJ45, and additional HDMI and USB ports. Audio is delivered through two 20W speakers, and the unit supports modern wireless standards including WiFi 6 and Bluetooth 5.2. The display weighs 58 kg and measures 1953.2 by 1151 mm, coming equipped with a wall mount bracket, two pens, and a remote control.
