There are two kinds of poster display prevailing on the market – LED poster display and LCD poster display. Many customers will choose one of them to advertise their products and transmit information. However, there is a common confusion about these two innovative advertisement screen: what are the differences between LED poster display and LCD poster? When we make the decision, should we choose LED poster screen or LCD poster?

In this article, we will try to figure this out for you by guiding you to understand the conceptions of LED poster screen and LCD poster, and their specialties to help you do the decision based on your specific needs.

So, let’s begin. First of all, we will start by knowing that what is LED poster and LCD poster screen.

LED poster screen or LCD poster

1. What is LCD poster?

LCD stands for liquid crystal display. LCD doesn’t produce light directly, it has a backlight to help to produce images. That means, if you want it to light up, there should be a light behind it cause it emits no light of its own. The light is what we call “backlight”.

Just imagine the structure of LCD display as a sandwich that has different layers: First, you have a polarizing filter on the top layer, then you have a protective layer behind it, followed by the LCD sheet, and then a backlight at the back.

LCD displays are usually used in the indoor environment and the ambient light is often limited and controlled. It owns advantages such as high definition, elegant appearance, lower initial price point if you only want a small screen, etc.

2. What Is LED Poster Screen?

The full name of LED is Light-emitting diode, and it provides its own light, meaning there is no need for backlight. By lighting up or go out the light beads, it can show specific images on the screen.

LED poster screen can be used both indoor or outdoor with high waterproof and dustproof ability. Besides, it has high contrast and high brightness, allowing it to be strong to resist the change of ambient light.

3. LED Poster Screen or LCD Poster?

After we know the conception and working principle of LED poster display and LCD poster, what are the differences between them?

1)Power consumption

The ratio of power consumption of LED poster and LCD poster is about 1:10, which means poster LED display is much more energy-saving than the latter one.

Such difference comes from their structure, and consider the electricity cost as one of your important factors when considering the budget as the cost of display power consumption will be a large part of your operation cost.  

2)Refresh rate

Overall, poster LED screens have a higher refresh rate as LED display screens can convert electrical energy to optical energy.

A high refresh rate can contribute to less latency and less ghosting when displaying videos. Moreover, higher resolution and wider color gamut.


Generally speaking, LED display has higher brightness than LCD display, and this advantage will play a more prominent role for outdoor using scenarios. For example, under direct sunlight, sometimes the brightness should be more than 4600nit to show the contents clearly. And the brightness of LED screens can even up to ten thousand nits, meaning there is no fear of the strong ambient light.

However, the maximum brightness of poster LCD screen is around 3000nit, which makes it be not suitable for outdoor applications.

4)Customized ability

One of the main differences lays between LED poster and LCD poster is the customized ability. Many LED poster manufacturers will accept customized cabinets, while LCD screens often can not meet such requirements. The manufacturers usually only produce LCD cabinets with specific specifications.

5)Viewing angle

LED display has a wider viewing angle which can up to around 180°to ensure people can see the images clearly from different angles, while that of LCD poster is narrower.

6)Working life( durability)

Generally, the life span of LED poster can reach more 80,000 hours while that of LCD screen is shorter, especially when customers place them in outdoor applications.

The LCD displays for outdoor applications sometimes will be overheated thus leading to system halted. Many LCD posters can only keep the normal working condition for several months or a year, then needed to be returned to the producers for service. The whole life span usually will be less than 2-3 years.


The thickness of LED poster screen usually thinner than that of LCD poster as the structure of LCD screen have more layers, as what we have mentioned above.

8)Color gamut

Full-color LED display has a wider color gamut so it has less color distortion and more vivid expressive force.

9)Initial price point

LCD technology has been in widespread use since the early 70s where it is first applied to digital watches. Therefore, the initial price is comparatively low. However, when the screen size is large, then choosing LED display can be more favorable conversely.

10)4K display

Many LCD display can not support 4K display, while LED display can realize true 4K definition. In the market where higher resolution rises more customers’ attention, 4K functions is undoubtedly an outstanding advantage.

To Sum up

In this article, we dicussed the differences between LED poster screen and LCD poster, and their conceptions.

The main difference is the materials – LCD screen needs a backlight to produce images while the LED display can produce by itself. And the development of technologies give them different advantages over each other.

In a word, LCD poster may have a lower initial price when customers only need small screens, however, it is weaker than LED display board, and has lower brightness, so it is only suitable for indoor application in most situation, and the size of the screen should not be too large.

But LED poster screen can be used for both indoor and outdoor and has higher contrast, higher resolution, and wider viewing angle and color gamut, which can really achieve high brightness with low power consumption. It also owns a much longer working life than that of LCD poster. Moreover, it accepts customized cabinets to meet more requirements for applications. The energy-saving capability, longer working life, higher brightness, and customized cabinet all make it take a large market share in the display industry.
