How to Communicate with LED Suppliers as a Beginner
Purchasing an LED display for the first time? Start by asking the right questions.
First, define your application needs. Check whether it is an indoor – fixed – installed LED screen, or an outdoor – fixed – installed LED screen, or an indoor – and – outdoor – universal LED screen.
The following are the differences in their functions, performances, and application scenarios.
Functional differences
Indoor – fixed – installed LED screens:
Usually have clear display functions, capable of presenting delicate images and rich colors, suitable for close – range viewing.
Some products also support the display of high – definition videos, images, and text information, and are often used to play presentation content and promotional videos.
Outdoor – fixed installed LED screens:
In addition to basic display functions, they often have remote control and timed on-off functions, facilitating content display and management at different times.
They can also be integrated with advertising delivery systems to achieve precise advertising delivery and management.
Indoor and outdoor universal LED screens:
They integrate some functions of both indoor and outdoor screens.
They can be used for high – definition display indoors and also meet certain viewing requirements outdoors.
For example, they have multiple signal access functions and can be connected to various devices such as computers, televisions, and cameras.
Performance differences
Brightness:
The brightness of indoor screens is generally between 800 and 2000 nits, and too high brightness will be dazzling; that of outdoor screens is usually above 5000 nits, even up to 8000 nits, to resist direct sunlight; the brightness of indoor – and – outdoor – universal screens can be adjusted, and it can be increased to around 3000 – 6000 nits when used outdoors.
Protection level:
Indoor screens have a relatively low protection level, ge nerally IP43 or IP54, mainly for dust -prevention and splash – proofing; outdoor screens are at least IP65, and even IP68, with water – proof, dust – proof, anti – ultraviolet, and weather – resistant properties; indoor – and – outdoor – universal screens can reach a protection level of about IP65, taking into account the protection requirements of both indoor and outdoor environments.
– Pixel pitch:
Indoor screens are for close range viewing, with a small pixel pitch, mostly below P3, and some can reach P0.9; outdoor screens are for long – distance viewing, with a large pixel pitch, mostly between P4 and P20; the pixel pitch of indoor – and – outdoor – universal screens is moderate, generally between P2 and P8.
– Viewing angle:
Indoor screens generally adopt SMD technology with a large viewing angle of up to 140 degrees; outdoor screens use LAMP technology with a small up – and – down viewing angle of about 60 degrees; indoor – and – outdoor – universal screens have a relatively large viewing angle, with both horizontal and vertical viewing angles exceeding 120 degrees.
Application scenario differences
– Indoor – fixed installed LED screen
Suitable for indoor places such as conference rooms, exhibition halls, theaters, shopping malls, and monitoring centers. For example, in conference rooms, they are used to display meeting materials and presentation content; in exhibition halls, they are used to display exhibit introductions and promotional videos.
– Outdoor – fixed installed LED screen
Commonly used in large outdoor squares, commercial streets, transportation hubs, the outer walls of sports venues, etc. For instance, in commercial squares, they are used to play advertising promotional videos; in transportation hubs, they are used to display flight and train schedule information.
– Indoor – and – outdoor installed LED screen
Suitable for some places that have certain requirements for environmental adaptability but are not in extreme outdoor environments for a long time, such as store windows, semi – open commercial blocks, and temporarily – built display areas at event sites.
Legidatech’s Ehonor Series is an excellent choice due to its ultra-thin 70mm profile and front-magnetic maintenance features.
Finally, highlight any special requirements.
For example, high refresh rates (≥3840Hz) eliminate flicker during photography, lightweight panels (3KG each) simplify installation, and curved configurations enhance creative displays. The Ehonor Series’ modular design supports right-angle and column splicing, making it versatile for unique setups.
Premium vs. Low-Quality LED Screens: Key Differences
Legidatech’s Ehonor Series sets a benchmark for excellence. Its unmatched refresh rate of ≥3840Hz ensures flicker-free visuals, ideal for live broadcasts and churches and other lecture meetings.
The robust build includes a fireproof V-0 ABS casing and a turbo-cooled back cover, which prevents overheating even in high-temperature environments.
The seamless uniformity of the display is achieved through short signal paths, reducing interference and delivering consistent colors (68.7 billion shades) with 160° wide viewing angles.
In contrast, low-quality screens often suffer from diminished brightness. For instance, a screen advertised as 800 nits might drop to 300 nits under testing.
Cheap components, such as non-certified materials, can crack under heat or humidity.
Additionally, ghosting effects caused by low refresh rates (≤1920Hz) result in motion blur, ruining the viewer’s experience.

LED Industry Scams: Tactics and Real-World Cases
A real-world case, a hotel that purchased a “4K LED wall” that malfunctioned within weeks. Third-party testing revealed recycled diodes and a 60Hz refresh rate, far below the promised 3840Hz.
Another issue is fake certifications—suppliers may claim “IP65 waterproof” for screens that are only suitable for indoor use.
Legidatech’s Ehonor Series avoids such pitfalls by using genuine IP31-rated casings, ensuring reliability.
Hidden costs are another trap. Many vendors promote “free installation” but exclude essential components like wiring or brackets, inflating the budget by 30%.
Top 3 LED Suppliers & Brands to Avoid
When selecting a supplier, prioritize trusted manufacturers. Legidatech leads the pack with its Ehonor Series, designed for premium indoor installations.
Other reputable brands include Absen (known for rental and stage displays), Unilumin (specializing in curved setups), Leyard (government and enterprise solutions), and Samsung (high-end commercial screens).
Avoid brands like GlowFake, which falsifies brightness certifications, or PixelGhost, which uses reclaimed components.
BrightScam is another red flag, selling non-fireproof screens falsely labeled as “V-0 certified.” Always verify certifications and demand third-party test reports before purchasing.
LEGIDATECH’s products have passed the certification of ROHS, FC and CC certificates.
