Product Descriptions
Product Features
Easy Assembly For Any Size Display
The L Series consists of minimal components that are lightweight, rigid and connect easily. Sub frames are either 2’x4′ or 3’x4’and consist of LED modules connected to a common control box via combined data/power cables. Displays can be assembled in shop or on-site from standardized components stored in inventory, ready to be combined into any size display.
Durability Beyond Typical Displays
The L-Series outdoor LED display frame cabinet is engineered to withstand wind load force of up to 150 MPH. All aluminum module design further protects display against warping due to excessive heat common in typical LED displays.
Reinforced Frame Design
All extruded aluminum sub frames are reinforced with corner gussets to ensure lateral stability and overall rigidity.
Easy Service Access
There are only 3 internal components in the L-Series outdoor LED display system – the main controller, the module controllers and the LED modules. All components can be accessed from the rear or with a simple hex tool from the front.
Built in Safety
If the L-Series requires service, technicians will not need to handle loose LED modules. Each LED module is connected to internal safety cables to ensure safety and improve ease and speed of service.
Performs in All Weather
Unlike typical outdoor LED displays, the Envoltage L-Series is IP-67 rated, protecting internal electronics from dust, water or any pollutant. And no fans are required. The all aluminum casing acts as a heat sink and provides superior radiated thermal management.
Common Cathode LED Technology
Common cathode LED technology means individual LEDs are connected via their negative ends and driven by positive ends. In common cathode mode, R, G, B chips are separately powered with voltage and current precisely distributed to red, green, and blue diodes, and the current passes the diodes then to the negative ends of ICs.
Common Cathode VS Common Anode LED Schematic Diagram
What is the difference between the common cathode / common anode LED display?
Power supply direction. With common anode LED displays, the current flows from the PCB board to the led lights, and the RGB led light is uniformly powered, which increases the forward voltage drop of the circuit. With common cathode LED displays, current passes through the led diode to the IC negative pole as positive. The pressure is reduced and the internal conductive resistance is small.
Power supply voltage. Typical common anode LED displays send red, green and blue LED diodes voltages higher than 3.8V (such as 5V unified power supply), so the power loss is high. Common cathode LED displays base transmission on the actual voltage required by the red, green and blue LED diodes (the voltage of the red LED diode is about 2.5V and the voltage of the blue and green LED diodes is about 3.8V). This dramatically lowers the heat generated during operations of the display.
Why does common cathode technology generate less heat?
Based on accurate power control, common cathode technology can reduce the power consumption of the entire system by reducing the red LEDs’ supply voltage. Moreover, there are no extra line-scanning devices needed to achieve this. By using common cathode technology, LED display can reduce excessive heat and power consumption, pixel failure rate, and ghost lines (tailing effect), thus improving LED display’s overall performance.
How does common cathode technology save energy?
Electricity& Operating costs. Precision power supply reduces LED display power loss, saving operating costs.
Equipment investment. Lower heat generated from LEDs negates the need for fans and cooling equipment.
Maintenance and repair costs. Electronics are fully enclosed in a die-cast aluminum bottom shell, which provides superior heat dissipation increasing lifespan to about twice that of conventional led screens.
Assuming that under common anode mode a 5V voltage is used as the unified power, under common cathode mode a 2.8V is used for red LEDs, and all other conditions are the same, if the current of red LEDs accounts for 40% of the total current, then we can quickly calculate the percentage of power saved: 40%*(5-2.8)/5=17.6%. If the LED current accounts for 50% of the total current, then we can save 50%*(5-2.8)/5=22%. Therefore, there is a theoretical 17.6%~22% power savings using common cathode technology over common anode technology.
Outdoor LED Displays – Knowledge Base
What Are Outdoor LED Displays?
Outdoor LED displays are large-format digital screens specifically engineered for use in open-air environments. They use high-brightness light-emitting diodes (LEDs) to deliver clear, vibrant visuals in direct sunlight, low-light conditions, and nighttime settings. These displays are designed to operate reliably in harsh weather, including rain, dust, heat, cold, and wind.
Key Features of Outdoor LED Displays
Outdoor LED display systems incorporate rugged construction and advanced display technology to ensure long-term performance. Common features include weatherproof enclosures (typically rated IP65 or higher), high nit brightness levels for sunlight visibility, wide viewing angles, and durable materials resistant to corrosion and UV exposure.
Modular cabinet designs allow outdoor LED displays to be built in virtually any size or shape, making them suitable for both large-scale video walls and compact information displays. High refresh rates and precise pixel control ensure smooth video playback and sharp image quality, even for fast-moving content.
Common Applications
Outdoor LED displays are widely used across commercial, municipal, and entertainment environments, including:
- Digital billboards and roadside advertising
- Building façades and architectural media
- Sports stadiums and arenas
- Transportation hubs and parking facilities
- Retail centers and outdoor shopping districts
- Public plazas, campuses, and event venues
Benefits of Outdoor LED Display Technology
Outdoor LED displays offer superior visibility compared to traditional signage and LCD-based solutions. They provide long operational lifespans, energy-efficient performance, and lower maintenance requirements over time. Remote content management systems allow operators to update messaging in real time, making outdoor LED displays ideal for advertising, branding, public messaging, and wayfinding.
Durability and Performance
Designed for continuous operation, outdoor LED displays are built to withstand extreme temperatures and environmental exposure. Advanced thermal management, sealed electronics, and robust mounting systems ensure stable performance and reliability in demanding outdoor conditions.
Why Choose Outdoor LED Displays?
Outdoor LED displays provide a scalable, high-impact digital signage solution that combines durability, flexibility, and visual performance. Their ability to deliver dynamic content in any lighting condition makes them a preferred choice for organizations seeking maximum visibility, audience engagement, and long-term value in outdoor digital signage installations.
