LED posters: freestanding indoor and outdoor displays

What is an LED poster?

An LED poster is a freestanding LED screen in portrait format, built from 320 × 160 mm LED modules, with a player inside. It replaces a printed poster or a light box with moving, changeable content. You load content from a phone, over a network or from a USB stick, and the poster keeps playing on its own. High refresh rates make video look smooth and reduce flicker when the screen is filmed, and brightness is adjustable, so the same poster works in a bright lobby and a dim exhibition hall. Tall freestanding screens like this are called pylons in some markets, for example in Malaysia and Southeast Asia.

Why resolution matters more than size

Every poster in the range has the same screen size: 640 × 1920 mm, 960 × 1920 mm or 1280 × 1920 mm. What changes with the pixel pitch is how many pixels fill that size. At P2.5 a 640 × 1920 mm poster shows 256 × 768 pixels; at P1.25 the same poster shows 512 × 1536 pixels, four times as many. More pixels give sharper text, cleaner edges and let viewers stand closer. The cabinet decides how you service and move the poster. The pitch decides how the picture looks.

The table gives the pixel resolution of one poster by pitch and size, computed from the module data.

Outdoor posters use the same 640 × 1920 mm screen with coarser pitches for longer viewing distances:

When posters are joined into one screen, the pixel counts add up. The sizes below are for indoor chains:

Pitches never mix in one chain. Choose the pitch from the distance of your nearest viewer, and test your own artwork before you order.

Reading distance: 1, 2 and 3 meters

The minimum viewing distance in meters is roughly the pitch in millimeters. This is a guide, not a promise: it depends on your artwork, so test it at the distance of your nearest viewer.

How the types differ: the cabinet, not the size

The same 320 × 160 mm modules and the same pitches are used in the indoor types. What changes is the cabinet around them: how the poster is serviced (from the front or the back), what protects the LEDs (GOB, an acrylic glass screen or the outdoor build), whether posters can be joined, and whether the poster folds, has two faces or goes outdoors. Cabinet types explained compares them in detail.

Choose your poster type

GOB is included on every indoor type except the acrylic glass screen, where the glass does the protecting. A clear layer over the LEDs helps hold them in place and protects them against knocks, dust and the light moisture of normal cleaning.

Applications

Retail and shopping centers. Entrance, promotion and concourse posters that roll in place and need no wall fixing. P2.5 (256 × 768 px on a 640 poster) suits viewers from 2.5 m; the outdoor 640 suits the storefront.

Restaurants and quick service. Menu and offer boards near the counter; P1.86 or P2 where guests read at 2 m. A built-in speaker is Optional. For touched or wiped areas see the acrylic glass screen.

Hotels. Reception and lobby: events of the day, directions, restaurant and spa notices. The 960 poster gives a wider canvas at P1.86 to P2.5.

Museums and cultural venues. Program and exhibition information in portrait format, with no wall drilling; P1.538 to P1.86 where visitors read closely.

Transport. Indoor concourses and waiting areas. A daisy chain of posters can form a main information screen, for example 8 × P2.5 at 2048 × 768 px with a NovaStar controller.

Events, showrooms and exhibitions. Foldable, tri-fold and double-sided posters move easily; flight cases are Optional.

Education. Entrances, libraries, training centers and campus buildings: schedules, news and announcements.

Daisy chain, cascade, splicing: what the words mean

Buyers use several words for joining posters. Daisy chain or cascade means the video signal runs from one poster to the next, from the HDMI output of one to the input of the next. Splicing means placing posters edge to edge so they read as one wider screen. Showing the same content on separate posters is something else: it is synchronized playback, and it needs no chain. Splitting one picture across several posters is what the chain is for. We use daisy chain as the main term. Which posters can join is stated on each page: double-sided and acrylic posters stand alone, while die-cast and tri-fold posters can be chained.

Control systems

• NovaStar control + Mean Well power supplies: the default set.
• Huidu or Colorlight control: a lower-cost option.

The control system is chosen to your task and does not depend on the cabinet. Receiving cards and controller are matched to one brand, so state your system when you ask for a quote. In a daisy chain a cascade controller replaces the control card in each poster. With a NovaStar controller, up to 8 posters chain at P2.5 and up to 6 at P1.86; with a Huidu controller up to 6 at P1.25 (these figures apply to the 640 die-cast poster). For other pitches and types, including aluminium profile 640 posters with rear door and tri-fold posters, the number of posters in one cascade is set by the total pixel count the controller and its receiving cards can drive, so it depends on the pitch. At the same pitch a 960 poster carries 1.5 times the pixels of a 640 poster and an open tri-fold twice as many, so fewer of them fit on one controller. We calculate it for your layout; tell us the width you need. Pitches never mix in one chain.

How ordering works

Our site is a closed RFQ: tell us the type, pitch, quantity, destination and control system, and we send a quotation. Price, MOQ and lead time are quoted per order. Samples are available. We sell EXW / FOB Shenzhen: we prepare the goods and export documents, and you arrange freight, duties and import compliance. Each poster is a complete unit with the player and power supplies. The warranty is 2 years with repair at the factory; spare parts are sold separately, and the buyer pays freight. Terms are confirmed per order.
