Many customers, when buying LED screens, initially think, "I just need a large, clear screen," but they don't understand the differences between indoor and outdoor LED screens. While the two types of screens look similar, their performance and other details are quite different!
Indoor LED Displays:
Usage Environment: Suitable for installation in shopping malls, exhibition halls, conference rooms, churches, hotel lobbies, and other indoor environments not exposed to direct sunlight, wind, or rain.
Brightness Requirements: Indoor screens typically have a brightness of 800-1500 cd/m². This is because most indoor locations (such as conference rooms, exhibition halls, shopping malls, and churches) have light intensity of around 300-500 lux, or even lower. If the LED screen's brightness is too high, for example, above 3000 cd/m², viewers' eyes will be constantly stimulated by the high brightness, easily leading to symptoms such as dry eyes and eye pain.
Protection Rating Requirements: The protection rating requirements are not high; IP30 is usually sufficient.
Pixel Pitch: Indoor screens are viewed from a relatively close distance, approximately 1 to 3 meters. Theoretically, the smaller the pixel pitch, the better, such as P1.5 or P2.5.
Installation Structure: To save indoor space and enhance aesthetics, indoor LED screens generally support hanging or wall-mounted installation.
Outdoor LED Displays:
Usage Environment: Designed for all-weather outdoor environments, such as billboards, building facades, squares, and sports stadiums. They must be rainproof, sunproof, and windproof.
Brightness Requirements: Outdoor screens typically have a brightness of ≥5000 cd/m². Under sunlight, if the brightness is too low, the entire display will become very dark, and the content will not be clear.
Protection Rating Requirements: Generally, an outdoor LED display needs to have a protection rating of IP65 or higher to be considered qualified.
Pixel Pitch: Outdoor screens are viewed from a longer distance, so a pixel pitch of P4, P6, or P10 is sufficient, and the price will be more affordable.
Installation Structure: Outdoor screens require a more robust and stable structure, often using steel frame supports, and are equipped with heat dissipation and lightning protection devices.
