How to Clean an LED Screen: The Commercial Owner’s Playbook
How to clean an LED screen the right way: safe products, a commercial SOP, cleaning frequency by environment, and the mistakes that kill walls.




The 1890*560mm LED Poster display, also known as “digital poster display”, is a highly integrated and portable LED display developed by UnifyLED LED Screen supplier.
Shenzhen UnifyLED Technology Co., Ltd. is a professional LED poster screen manufacturer offering a comprehensive range of high-quality display solutions. The 1890*560mm LED Poster Display is our self-developed private-model digital signage solution, featuring a slim 33mm-thick floor-standing frame measuring 1902×572mm and weighing just 27kg for easy repositioning across retail stores, shopping malls, and exhibition halls.
We designed it with a proprietary 210×280mm module in P1.75, P2.0, and P2.5 pixel pitches — including an outdoor-rated P2.5 variant — delivering 800–1000 nits brightness for crisp visibility in both indoor and semi-outdoor environments. Multiple units can be seamlessly spliced into a larger video wall or operated independently with synchronized or split-screen content, all manageable remotely via mobile phone. With its private-mold construction, slim profile, and plug-and-play setup, the LED Poster Display offers a turnkey digital advertising platform that stands apart from generic public-model alternatives.
This 1890*560mm LED poster screen is designed with a private mold. The pixel pitch has three options: indoor P1.75, P2.0, and P2.5. The outdoor poster screen only has a P2.5 pitch, ensuring that it can be viewed clearly at close range and provides high-definition pixels. Even for indoor poster screens, P2.5 is the most commonly used pitch.
After multiple 1890*560mm LED poster screens are seamlessly spliced, the display modes are diverse. They can display the same content to expand the display area and influence of the advertisement.
They can also display different contents separately to present the diversity of content. This creative form is also one of the ways to attract audiences.
