In this fast-paced world, effective communication is critical. Having the right display technology can make a difference in this aspect. It is where indoor LED screens come in.

These dynamic displays offer unparalleled brightness, clarity, and energy efficiency. So it has become a popular choice for a wide range of applications. You can easily find them in advertising, entertainment, and education. In this article, we will introduce indoor LED screens.

What is an indoor LED screen?

An indoor LED screen is an indoor display using LEDs to create bright and dynamic images and videos. LED screens emit light directly from the diodes. It is unlike LCD illuminating with backlight. Therefore, LED displays are more efficient and precise in lighting control. They are ideal for high brightness and contrast indoor applications:

  • Stadiums
  • Retail stores
  • Corporate events
  • Other public spaces.

LED screen working principle is relatively simple. We encapsulate tiny red, green, and blue LEDs on flat panels. We also call them LED modules. When electrical current passes, they emit light at different intensities and colors. There is a processing unit to control the LEDs. This unit receives signals from a video source. And it converts them into commands to control the LEDs’ brightness and color. So we can see smooth and bright videos.

Advantages of indoor LED screens:

Indoor LED screens have several advantages over LCDs and projectors. Here we will discuss this aspect:


One of the most significant advantages of indoor LED screens is their brightness. LED video walls are much brighter than traditional displays. Generally, indoor LED displays’ brightness can reach 600 nits at least. If you need much higher luminance, we can provide solutions to offer you 1,000~5,000 nits. As a result, they are ideal to use in high-brightness environments.

Energy efficiency:

This is another feature of LED screens. Due to their energy-saving, you can save a lot of power over time. You can refer here if you want to know more about their power consumption.

Because they produce less heat, LED screens are also more environmentally friendly.


Indoor LED screens are also very durable. As we know, their life span can reach ten years. Besides, their operating temperature range can be from -40℃ to +70℃. So it makes sure they are no problem operating in extreme weather.

Except for the above, they are also resistant to impact and vibration. Therefore, we can use them in areas with high foot traffic. For instance, we often see them in pubs, discos, etc.

Types of indoor LED screens:

Here we will mainly talk about four types of indoor LED screens. They are according to their unique features and advantages:


It is the most common type of outdoor and indoor LED screen nowadays. We mount each LED chip onto the PCB surface of SMD LED screens. They have a high resolution, a wide viewing angle, and different pixel pitches. Below are some common models of indoor types:

  • P1.25
  • P1.5
  • P1.86
  • P2
  • P2.5
  • P3

The SMD indoor is with a light weight cabinet design and ultra slim depth. For instance, a 640×480 mm cabinet weighs about 7kg. And the thickness is about 6.5cm. So it is easy for you to install.

GOB means glue on board. It is similar to SMD LED screens in construction. However, an additional layer of epoxy resin covers the LEDs for GOB. It provides many advantages:

  • Improved durability.
  • Better moisture resistance.
  • Increased protection against damage from impact or vibration.
  • Reduce light reflection and improve color accuracy.

If you need to move the screen frequently, GOB LED screens are a better choice. It is not easy to damage the LED lamps around the corner. So you don’t need to worry anymore during the operation. Such applications can be mostly in rental or staging events. They are also suitable for areas with high humidity, such as indoor swimming pools or saunas.

Every coin has two sides. Here we will list GOB disadvantages:

  • Hard to repair.
  • The heat dissipation is not as good as the SMD type.
  • The layer may affect the flatness of the display surface.
  • The screen brightness is lower.
  • Higher cost on the manufacturing.

Indoor LED Screen


COB refers to chips on board. It is a newer type of indoor LED screen. We mount multiple LED chips directly onto a circuit board. As a result, we can make higher-density and lower-pixel-pitch screens.

COB LED screens are more reliable and efficient than SMD types. It is because they have fewer soldering points and a better heat dissipation system.

Indoor LED Screen

Mini-LED screens:

They are the latest and most advanced type of indoor LED screens. They consist of a large number of tiny LED chips. These chips are smaller than those for SMD and COB types. Therefore, the mini type allows for a much higher resolution and smaller pixel pitch.

Mini-LED screens offer a higher contrast ratio, deeper blacks, and a wider color gamut. However, they are currently more expensive than other types of LED screens.

Applications of indoor LED screens:

We can use indoor LED screens for different purposes. Here are some of the most common applications:


It is the most popular application for LED screens, particularly in commercial fields. So, we can also call them advertising LED screens.

LED screens can capture the attention of passersby with their eye-catching ads. So you can use them to display promotions or product information.
