Outdoor P3.91 Lightweight LED Transparent Screen Display For Shopping Mall Windows

4. High Brightness

Currently, most outdoor display screens on the market offer a brightness of 5000 cd/m². However, this value does not account for optical attenuation. The international industry standard for outdoor displays is 5000 cd/m². Based on an LED light decay rate of 5% per year, after one year the brightness will drop to only 4750 cd/m², after two years to 4500 cd/m², and after three years to 4250 cd/m². In other words, for ordinary products, after just one year of operation, the display performance will be significantly degraded.

The Lanxi Pro series, however, is available in two models. One model is designed for general stage rental applications, with a brightness of 4000–5500 cd/m², ensuring normal visibility of displayed content under everyday sunlight conditions. The other model delivers a high brightness of 5500–7000 cd/m² for all‑weather outdoor advertising, ensuring that content remains clearly visible even under direct sunlight at summer noon. With its high brightness of 7000 cd/m², the display can still maintain standard brightness levels even after 8 years of attenuation.

5. Drive Modes: 1/2s and 1/4s

To reduce costs, many similar products on the market adopt 1/8, 1/16, or even higher scan modes. However, under harsh outdoor conditions, these higher‑scan designs result in higher failure rates (frequently causing large‑area dead pixels and insufficient brightness). To ensure reliable outdoor operation, the TTO series employs the more costly 1/2s and 1/4s scan modes. This choice provides strong assurance for excellent display quality, reduces brightness loss, and significantly lowers the overall failure rate of the screen.

6. High Refresh Rate

LED screens with low refresh rates are prone to flickering images, which cause visual discomfort and may even harm the eyes. They also produce motion blur and trailing artifacts when displaying fast‑moving content. The Lanxi Pro series features a high refresh rate of 3840 Hz, ensuring stable, flicker‑free, and black‑screen‑free image capture. It effectively eliminates trailing and blurring during rapid motion, enhances image clarity and contrast, and delivers smooth, delicate video performance that remains comfortable for prolonged viewing.

Fanless air conditioning cooling, environmentally friendly and energy-saving.

(Ambient Room Temperature: 28°C)

However, as can be seen from the table of brightness and corresponding temperature test data of the Lanxi Pro series above, the TTO series has good temperature control capabilities, does not require fans or air conditioning for heat dissipation, and consumes only 1/3 of the power of conventional outdoor LED screens, making it more energy-efficient and environmentally friendly.

7.Independent Waterproof and Moisture‑Proof Design – The screen achieves an IP65 protection rating on both front and rear, with excellent cabinet sealing. This is realised through the use of high‑protection‑grade outdoor LED lamps, secondary potting/encapsulation of the lamp surface on the PC‑material module frame, and sealing‑ring gaskets applied to both the connector modules and the power supply modules.

8.Windproof: The hollow box structure design allows for ventilation and strong wind load capacity; at the same time, the modular light panel has a reinforced design, which improves wind and torsional resistance by 2 times without affecting transparency and aesthetics.

9.Highly weather-resistant: The PC material light strip module, combined with the full potting design of the front light panel, provides high UV resistance, corrosion resistance, salt spray resistance, and strong UV resistance. It can be used in ambient temperatures ranging from -20°C to +50°C, making it suitable for use in extreme temperatures and ensuring durability.

10.Lamp panel cover design: The front is equipped with a lamp panel cover design, which not only effectively protects the lamp beads, but also prevents glare and prevents water and dust accumulation on the lamp surface, thus enhancing the product's anti-strong light, dustproof and waterproof performance.

The front panel has been enhanced with a light panel cover design.

11.Enhanced protection stems from meticulous attention to detail. The superior outdoor protection and professionalism of the Lanxi Pro series also come from meticulous attention to detail—high-protection-level aviation connectors; inner and outer arc-shaped housing assembly buttons and quick-lock design.

Application scenarios

Transparent LED Screen – 10 FAQs (English Version)

1. Q: What is a transparent LED screen? What are its main applications?
   A: A transparent LED screen is a high‑transparency display primarily used for stage design, shopping mall window displays, building glass curtain walls, and outdoor storefront advertising, delivering dynamic video content while preserving natural daylighting.

2. Q: What are the key specifications of the outdoor P3.91 transparent screen?
   A: Pixel pitch P3.91×7.81mm, cabinet size 1000×500mm, thickness only 63mm, 45% transparency, weight per unit area 18.4kg/m² – approximately 50% lighter than conventional outdoor screens.

3. Q: What brightness levels are available? Is it visible under sunlight?
   A: Two versions: Standard (4000–5500 cd/m²) for normal sunlight visibility, and High‑brightness (5500–7000 cd/m²) for clear visibility even under direct summer noon sun. The 7000cd/m² version still meets standard brightness after 8 years of attenuation.

4. Q: What is the protection rating? Can it withstand harsh weather?
   A: IP65 on both front and rear. Independent waterproof design, secondary potting of LED lamps, and sealing‑ring gaskets for connectors effectively resist rain, dust, moisture, and strong light interference.

5. Q: What is special about the drive mode?
   A: The TTO series uses high‑cost 1/2s and 1/4s scan modes, significantly reducing failure rates (dead pixels, insufficient brightness) in harsh outdoor environments compared to common 1/8 or 1/16 scan designs.

6. Q: What is the refresh rate? Does it handle fast motion well?
   A: The refresh rate is 3840 Hz, eliminating flicker and motion blur. It delivers smooth, delicate video that is comfortable for prolonged viewing and ensures flicker‑free camera capture.

7. Q: Can it be curved? What installation methods are supported?
   A: Yes, it supports ‑5° to +5° convex/concave curved splicing. Multiple installation methods include stacked (floor), suspended (ceiling), and floor‑stand mounting, suitable for various mid‑to‑high‑end applications.

8. Q: Is maintenance convenient? Is a service aisle required?
   A: The modular design (independent structure/control/display modules) with concealed power supplies and receiving cards supports front‑and‑rear maintenance, eliminating the need for reserved service aisles.

9. Q: How does the cost compare to conventional outdoor LED screens?
   A: Transparent screens have higher initial costs due to hollow‑out aluminium structures, high‑protection lamps, and low‑scan drive modes. However, their low failure rate, long lifespan, and no extra structural reinforcement often result in better total cost of ownership.

10. Q: What about operating temperature and heat dissipation?
    A: At room temperature 28°C and 7000cd/m² brightness, the LED surface center reaches ~80.2°C, rear cover center ~65.3°C, and edges only ~36.9°C. The hollow‑out design and aluminium construction ensure effective heat management for long‑term stability.
