Introduction to the 75" 4K Interactive Flat Panel (DS-D5C75RB/B)
Overview
The DS-D5C75RB/B is a 75-inch 4K interactive flat panel built for modern classrooms, meeting rooms and hybrid workspaces. Combining a 3840×2160 UHD VA panel with anti-glare tempered glass, a responsive infrared touch system supporting up to 50 simultaneous touch points, and an integrated Android 13 platform (8 GB RAM / 128 GB storage), this all-in-one display targets educators and corporate teams who need an intuitive, collaboration-ready surface. Onboard video and audio hardware — including a high-resolution 48MP camera and an 8-array omni-directional microphone — make it a strong choice for hybrid teaching and conferencing. The display is competitively positioned with an RRP of approximately US$2,999.

Detailed specifications and the benefits they deliver
The DS-D5C75RB/B uses a 75-inch VA panel at true 4K UHD resolution (3840×2160) running at 60 Hz. A 10-bit colour depth and a 5000:1 static contrast ratio help produce deep blacks and smooth colour transitions, useful for detailed imagery, high-resolution video playback and visual learning materials. Typical brightness is 400 cd/m², sufficient for most classroom and boardroom lighting conditions; the anti-glare zero-lamination tempered glass (9H) reduces reflections and keeps the image legible under bright lights while protecting the panel surface from daily wear. A quoted lifespan of around 50,000 hours means the display is built for long-term deployments.
Infrared multi-touch technology supports up to 50 simultaneous touch points with sub-2 ms response and ±0.5 mm precision. This level of responsiveness benefits collaborative group work, multi-user annotation sessions and interactive lessons where multiple students or participants may interact at once. A high touch resolution (32,767 × 32,767) ensures accurate pen/stylus tracking and fine writing.
The integrated Android 13 environment (Octa-core CPU with Cortex-A76 and A55 cores, Mali-G610 MC4 GPU, 8 GB RAM, 128 GB storage) runs native apps and whiteboarding tools directly on the panel with smooth performance. For organisations needing Windows-based software, the panel supports a Windows OPS module for dual-OS operation. This dual-OS flexibility allows IT teams to standardise on familiar desktop applications while keeping a simple tablet-like experience for day-to-day use.
Hybrid sessions are improved by a built-in 48MP photo camera and an 8MP video sensor (up to 4K video capture) with intelligent source switching. The 8-array omni-directional microphone offers echo reduction, noise cancellation and voice pickup up to about 12 meters, allowing presenters to be heard clearly without lapel mics in medium to large rooms. Built-in speakers (2×20 W + 25 W) provide adequate audio for typical meeting and classroom sizes.
Rich I/O includes multiple HDMI inputs, HDMI output, DP and VGA for backward compatibility, several USB 3.0/2.0 ports and two Type-C ports (the front Type-C supports 65 W charging for connected laptops). Dual 1 GbE LAN, Wi-Fi 6, BLE 5.1 and NFC mirroring cover wired and wireless deployment scenarios and make pairing devices quick and reliable. These connectivity options reduce the need for dongles and simplify hybrid session setups.
The unit accepts 100–240 VAC with average power consumption under 150 W. Its physical footprint (approx. 1713.2 × 1034.5 × 82.5 mm) and VESA 800×400 mounting make it compatible with common wall mounts and lectern installations. The display is EDLA certified per the manufacturer datasheet; integrators should verify regional CE/UKCA and electrical compliance and engage qualified installers for wall-mounted or recessed setups.
Use cases and scenarios where the panel excels
In classrooms the 75" size offers a large canvas for whole-class instruction. Teachers can display detailed diagrams, annotate in real time and invite groups of students to collaborate using multiple touch points. The anti-glare glass and high contrast help visibility from the back of a classroom, and the integrated camera/mic enable remote learners to participate without extra peripherals.
Lecture capture and hybrid seminars are simplified by the integrated 4K camera and multi-array mic. Professors can switch sources intelligently, annotate lecture slides directly on-screen and record or stream sessions. The panel’s resolution and colour depth better support scientific imagery, maps and multimedia content.
For boardrooms and training facilities the DS-D5C75RB/B supports video conferencing, digital whiteboarding and multi-user collaboration. The front Type-C with 65 W charging allows visiting presenters to plug in a single cable for video, audio and power. Dual-OS flexibility means IT can run Windows video conferencing tools via an OPS module while keeping a simple Android environment for quick meetings.
The high touch point count and pen precision make the display well suited for interactive workshops, design reviews and brainstorming sessions. Built-in connectivity and media playback capabilities also allow it to function as a large-format digital canvas for collaborative creation.
Comparisons with similar products in the market
Interactive flat panels from the likes of SMART Technologies (SMART Board), Promethean (ActivPanel), BenQ (Board series) and ViewSonic (ViewBoard) are the most direct competitors. Here are key differentiators and how the DS-D5C75RB/B stacks up.
- Touch point count and responsiveness: Many competing panels support 20–20+ touch points; the DS-D5C75RB/B’s support for up to 50 touch points is higher than average, enabling fuller multi-user scenarios.
- Onboard OS and performance: Android-based panels are common; Android 13 with an octa-core CPU and 8 GB RAM is a modern configuration that supports contemporary apps. Competing high-end models may provide similar RAM or Windows OPS integration, but the DS-D5C75RB/B’s balance of onboard power and optional OPS gives strong flexibility.
- Camera and audio: The integrated 48MP camera is higher resolution than many built-in camera solutions, and an 8-array mic with 12 m pickup provides strong room coverage. Some rivals rely on add-on camera bars or lower-resolution cameras, which can increase total cost.
- Connectivity and convenience: Front-facing Type-C with 65 W charging and Wi-Fi 6 are conveniences that match or exceed many competing panels, reducing the need for docks or adapters.
- Brightness and use environment: With 400 cd/m² typical brightness the panel is well suited for classrooms and meeting rooms but slightly less bright than specialized signage displays designed for high ambient light. For most education and corporate spaces this is sufficient.
- Value: At an RRP around US$2,999 the DS-D5C75RB/B positions itself competitively against flagship interactive panels that sometimes command higher premiums for brand names or proprietary software suites. The feature set delivers notable on-board camera/mic capability and high touch counts that differentiate value.
