The same picture, the same pixel pitch, the same cabinet size — and yet an outdoor screen costs noticeably more and weighs more. The difference is not the display. It is everything that has to survive outside.
The short answer
Indoor screens are optimised for colour and lightness at 600–800 nits. Outdoor screens are optimised for survival: 5,000+ nits, sealed enclosures, wider temperature range, and heavier frames. Using one in the other’s place fails on brightness (indoor used outdoors) or on cost and weight (outdoor used indoors).
1. Brightness, and why the gap is so large
An indoor screen at 800 nits is comfortable in a lit room. The same 800 nits outdoors at noon is unreadable, because daylight reflected off the screen surface is already brighter than the image. Outdoor cabinets run 4,500–6,000 nits for that reason.
Getting there needs more LEDs driven harder, bigger power supplies and more heat dissipation. That single requirement cascades into almost every other difference on this list. If you want the number for your own site, see how many nits an outdoor screen needs.
2. Sealing and IP rating
Indoor cabinets are usually open at the rear for airflow. Outdoor cabinets are sealed to IP65 on the front face — dust-tight and protected against water jets — with a lower but still protected rating on the rear, typically IP54.
Sealing is not a coating. It means gaskets, sealed connectors, a sealed power box and a front mask that sheds water. It also means the cabinet cannot rely on open-air cooling, which is the next problem.
3. Cooling
A sealed box full of LEDs at 6,000 nits gets hot. Outdoor cabinets use thicker aluminium, larger heat paths and in some cases active fans or air conditioning for high-brightness configurations. Indoor cabinets can often run passively because the enclosure is ventilated.
Temperature also sets the operating range. Outdoor units are specified to work from roughly −20 °C to +60 °C ambient; indoor units are usually specified for a narrow comfort range.
4. Weight and structure
Gaskets, thicker frames, larger power supplies and heavier masks add mass. A 500 × 1000 mm outdoor rental cabinet commonly weighs around 13 kg against 12 kg indoors — not dramatic, but it compounds across a 100 m² wall, and it changes what the truss has to carry.
5. LED packaging and the front mask
Outdoor modules usually use a louvre or shaded mask that cuts sunlight falling directly on the LED package, and black-bodied SMD parts to reduce reflection. Indoor modules can use a flatter mask tuned for wide viewing angle and colour consistency instead.
This is why two cabinets with identical pitch and identical nits can look different outdoors: the mask design decides how much ambient light reaches the LEDs.
6. Power and electrical
Higher brightness means higher current. An outdoor wall can draw two to three times the power per square metre of an indoor wall at the same size. That affects cable sizing, breaker count and generator requirements — see how to calculate LED screen power consumption.
Side-by-side comparison
| Indoor | Outdoor | |
|---|---|---|
| Typical brightness | 600–1,200 nits | 4,500–6,000 nits |
| Front protection | open or lightly sealed | IP65 |
| Rear protection | not rated | typically IP54 |
| Cooling | passive, ventilated | sealed, heat-path or active |
| Operating temperature | comfort range | about −20 to +60 °C |
| Weight, 500 × 1000 cabinet | about 12 kg | about 13 kg |
| Power per m² at full output | lower | 2–3× higher |
| Cost per m² | lower | higher |
Can you use one in place of the other?
Indoor screen outdoors: no. It will be unreadable in daylight and the first rain will find the electronics. Even under a permanent canopy, humidity and temperature swing will shorten its life.
Outdoor screen indoors: technically yes, and people do it for very bright lobbies or atrium walls. But you are paying for sealing and brightness you may never use, and carrying extra weight on the structure. Dim it via the controller or the LEDs will look harsh at close range.
What actually matters when choosing
- Will rain or dust ever reach the front or rear face? If yes, outdoor.
- Is the screen read in daylight, even indirectly? If yes, outdoor.
- Is the wall load-sensitive or the budget tight? Indoor, unless the first two answers are yes.
- Is the screen semi-outdoor — under a canopy, in a mall entrance? This is the grey area where a sealed cabinet with moderate brightness is often the right answer.
Indoor models such as the EA640F2 indoor LED display and the EA600COB3 indoor COB screen cover the interior case; the EA-OFixed outdoor fixed advertising board covers permanent exterior installation.
Frequently asked questions
Is IP65 needed for a screen under a roof?
Not always, but a semi-outdoor position still sees humidity and temperature swing. A sealed cabinet with 2,000–3,000 nits is often the better compromise than a fully open indoor unit.
Can an outdoor screen be used in a window facing the street?
Yes, and it is common. Watch the heat build-up behind the glass and confirm the brightness is dimmable for night.
Why is the outdoor version heavier if the cabinets look identical?
Gaskets, thicker aluminium, bigger power supplies and heavier masks. The visible dimensions stay the same for compatibility.
