Display and Touch Input

The HUAWEI IdeaHub B3 IHB3-75SA features a 75-inch 4K infrared touchscreen with D-LED backlighting. Zero-gap bonding technology eliminates the air gap between the glass and the panel, reducing touch input latency to 16 ms and ensuring sensor activation at distances no greater than 1.5 mm. Image geometric distortion is kept below 2%.

Conference Audio and Video

The device includes six microphones with a 180° pickup angle and a range of up to 10 m, operating in the 100 Hz – 20 kHz frequency range. Four speakers with a total output of 30 W reproduce sound in the same 100 Hz – 20 kHz range. The camera’s horizontal field of view is 80°, and automatic framing and smart tracking ensure proper shot composition without manual adjustments.

Support for BYOM (Bring Your Own Meeting) technology allows users to initiate conferences from their own laptops, using the display’s microphones, speakers, and camera as peripherals. Preinstalled Huawei Cloud Meeting and WeLink apps enable meeting launches directly from the device interface.

Dual Streams and Data Transmission

The HUAWEI IdeaHub B3 IHB3-75SA supports simultaneous dual-stream transmission: 1080p audio/video at 30 fps alongside 1080p data sharing at 15 fps, or a 4K data stream at 3 fps. This allows participants to see speakers and collaborate on content simultaneously without switching modes.

Computing Platform and Operating System

The hardware platform is built on an octa-core processor with 8 GB of RAM and 64 GB of flash storage. The base operating system is HarmonyOS; Windows operation requires an optional OPS module. NFC support enables quick authentication and pairing with mobile devices.

The display is equipped with a Wi-Fi 6 module operating in the 2.4 and 5 GHz bands and a gigabit RJ45 port with speeds of 10/100/1000 Mbps. The front panel features one Type-C port and two USB 3.0 ports for quick peripheral connections. The side panel includes 3.5 mm LINE IN and LINE OUT jacks, two HDMI IN ports, one HDMI OUT port, one USB 3.0 port, an RJ45 port, and a COM port for integration with external equipment.
