Product Detail
The P3.91 Transparent LED Screen from Leyarled is a factory-direct screen for retail glass facades and similar projects, built to run every day without babysitting. It uses a 3.91mm pixel pitch, 1920-3840 Hz refresh and a sealed cabinet, and it ships with the layout drawing, control configuration and spare modules already matched to your order.
P3.91 Transparent LED Screen: key features
- Front-service magnetic modules – a failed module is swapped in minutes without removing the cabinet from the frame.
- P3.91 transparent LED screen with 1920-3840 Hz refresh – no scan lines on camera and no visible flicker in video playback.
- Sealed cabinet with pressure valve – moisture cannot be pulled in when the screen heats and cools through the day.
- Calibrated at the factory before packing – brightness and colour are matched across cabinets so a 50 sqm wall still reads as one surface.

Panels are tested against IEC 60068 environmental test methods for temperature, humidity and vibration.
Product details
As we all know, ordinary LED display opaque, transparent rate is 0. The LED transparent screen high permeability, permeability rate of more than 60%, and the screen display effect is very cool.
The weight of a conventional LED single box is generally more than 20kg. When the screen area is too large, the screen steel structure and the original building structure are all challenging. The transparent LED display, single panel weight of about 12kg, can be installed independently of the vertical, the load requirements of the steel structure is very low.
The conventional LED display screen requires a large-scale steel frame structure at the time of construction, which takes a lot of time and labor and affects the shape and aesthetics of the building to some extent.When the LED transparent screen is installed, no steel structure is required, and a small amount of construction can be used to easily integrate the wall with the wall body without damage to the wall, and the overall appearance of the LED screen can also be improved.
When the conventional LED display screen is shaped as a product, due to the limitation of the structure of the LED box, excessive stitching is not natural, and there will be joints.The transparent LED display can be customized and spliced into a perfect LED special-shaped screen. The surface transition is natural and beautiful. It can support various shapes such as cylinders, round tables, triangles, and arcs.
The conventional LED large-screen screen has a problem, usually after the maintenance process, or the entire module or box removed for maintenance. The LED transparent screen eliminates the need to replace the entire module and only replaces a group of light bars. Maintenance is done indoors, with high efficiency and low cost. Only need to replace a light bar, the operation is simple and quick, reducing maintenance costs.
Where the P3.91 Transparent LED Screen is used
- Retail glass facades – advertising that keeps the shop interior visible from the street.
- Bank and brand showrooms – product launches behind glass without blocking daylight.
- Airport and metro glazing – wayfinding and advertising on existing window surfaces.
- Stage and event sets – see-through backdrops for camera work.
A note on the P3.91 Transparent LED Screen: on a glass facade the screen has to disappear when it is off, which is why the cabinet is finished in a dark matte coat and the cabling runs behind the mullions.
Installation, delivery and warranty
For the P3.91 Transparent LED Screen, transparent panels clamp onto the existing mullions or hang from a top rail, so no structural rebuild is needed. Cable routing runs along the frame and the sending card sits in a small enclosure behind the glass.
Transparency is roughly 55-75% depending on pitch, so check the sightline requirement before choosing p3.9 versus p7.8. Delivery is 7-12 working days for standard cabinets and 15-20 days for a full project with structure and control. The screen carries a 3-year warranty covering modules, power supplies and receiving cards, with spare parts held in Shenzhen for five years after the order.
Frequently asked questions
What is the lead time for a P3.91 Transparent LED Screen order?
Standard P3.91 cabinets ship 7-12 working days after the deposit clears. Custom cabinet sizes, curved frames or a project-specific power distribution add 3-5 days. We send a production photo set before the goods leave the factory.
Can you build this P3.91 Transparent LED Screen in a custom size?
Yes. Send the wall width, height and viewing distance and our engineer returns a cabinet layout, a resolution map and a power estimate within 24 hours. Non-standard sizes are cut from the same cabinet family, so spares stay interchangeable.
How is the P3.91 Transparent LED Screen shipped and what about spare parts?
Plywood case or flight case, sea or air freight, with a 2-3% spare module and power supply allowance included in the carton. Every order carries a serial list so a spare module can be matched to the cabinet it came from.
