ViewSonic LDM136-151C – 136-Inch Modular Direct View LED Display

Product Overview

The ViewSonic LDM136-151C is a 136-inch all-in-one direct view LED display built on Chip-on-Board (COB) LED technology, delivering Full HD 1920x1080 resolution in a bezel-free, commercial-grade form factor. Designed for corporate boardrooms, conference rooms, higher education auditoriums, and lobby installations, this dvLED display combines display, controller, power, and mounting hardware into a single part number, simplifying specification and procurement for AV integrators and facilities managers. The 1.56mm pixel pitch COB panel provides exceptional image quality and physical durability, with IP54 dust and moisture resistance and IK08 impact protection on the front surface. A built-in Android 9.0 media player and dual 30W speakers make this display a self-contained presentation and signage platform.

Product Description

The LDM136-151C addresses a consistent challenge in commercial AV: delivering a large-format, high-impact display that is straightforward to procure, install, and maintain. As a true all-in-one direct view LED solution, it ships with the display panels, integrated control bar, image processing hardware, power systems, wall mount, and accessories — everything an integrator needs is in one box and one line item. The 1.56mm pixel pitch COB technology produces a smooth, high-resolution image that holds up at close viewing distances typical of boardroom and conference room environments, where audiences may be seated as close as 6–8 feet from the screen. COB construction also encapsulates the LED chips in a protective epoxy layer, providing IP54 ingress protection and IK08 impact resistance — meaningful durability advantages over traditional SMD panels in high-traffic spaces. The 600-nit brightness and 10,000:1 contrast ratio deliver vivid, sharp visuals in rooms with overhead lighting or windows, avoiding the washed-out appearance common to projection systems. Four HDMI 2.0 inputs with HDCP 2.2 support laptops, video conferencing codecs, and media players, while RS-232, dual Ethernet LAN ports, and IR connectivity facilitate integration with room control systems. The detachable control bar can be mounted up to 30 feet from the display, allowing clean installations in rooms where the control electronics need to be positioned away from the viewing surface. Front access LED modules simplify maintenance — a vacuum tool is included for servicing panels without full display disassembly. With a 100,000-hour backlight life rating and a 3-year on-site service warranty, the LDM136-151C is built for long-term commercial deployment.

Technical Specifications

Frequently Asked Questions

• What is the advantage of COB LED technology over standard SMD panels? COB (Chip-on-Board) technology encapsulates the LED chips directly on the circuit board in a protective resin, resulting in a smoother surface, better resistance to physical contact (IK08), and improved moisture protection (IP54). This makes COB panels more suitable for high-traffic spaces where accidental contact is possible.
• Is the LDM136-151C an all-in-one solution — do I need to purchase a separate media player or controller? Yes, it is a complete all-in-one system. The display, image processor, power distribution unit, control bar, and wall mount hardware are all included. A built-in Android 9.0 media player handles standalone content playback. No additional controller is required for standard installations.
• What control systems can integrate with this display? The LDM136-151C supports RS-232 serial control and IP-based control via its dual Ethernet LAN ports, enabling integration with Crestron, AMX, Extron, and other third-party control systems. ViewSonic provides command code documentation for system programmers.
• Can the control bar be installed in a separate location from the display? Yes. The control bar is detachable and can be mounted up to 30 feet from the display panel, supporting clean architectural installations where electronics need to be in an AV rack or adjacent equipment room.
• What is the pixel pitch, and what viewing distance does it support? The 1.56mm pixel pitch is appropriate for viewing distances starting at approximately 5–6 feet, making it well-suited for boardrooms and conference rooms where participants are seated close to the display.
• What warranty does the LDM136-151C include? ViewSonic provides a 3-year limited warranty covering parts and labor with on-site service, reducing downtime compared to depot or mail-in repair programs.
• Does the display support HDCP content protection? Yes. All four HDMI 2.0 inputs support HDCP 2.2, enabling playback of protected content from streaming devices, Blu-ray players, and other HDCP-encrypted sources.
• What is the power requirement for this display? The LDM136-151C requires a 100–120V / 20A circuit. Maximum consumption is 1,095W; typical operating power is 400W.
