What is a P4 LED Display?

P4 LED displays are an iconic product of LED display, marking their entrance into the world of small pitch LED display. The P4 here refers to pixel pitch, which is 4mm.

P4mm LED display belongs to a range of small pixel pitch LED display screens. Its designed to satisfy the demand for high-quality pictures and videos on the screen.

Through continuous innovation in P4 LED screens, LED displays for many different application scenarios have been developed. They are frequently fixed on the wall to make an LED wall, which is used to display advertisements or other promotional information.

This is your all-in-one guide to understand what exactly are P4 LED displays.

General specifications

Although different manufactureres may offer specialised features in P4 LED displays, these tend to be the usual specs.

For a module size of 320 X 160 mm, the module resolution may be 80 X 40 dots. The brigthness tends to be 800 – 1,200nits (Adjustable) and the refresh rate for P4s is set at 1,920Hz ~ 3,840Hz. You can expect a standard panel of P4 LED display to be made either of

• Steel Iron,
• Magnesium Alloy  
• Bare

A typical power rating for P4 LED displays is 150W/m² with the maximum power rating being set at 450W/m^2.

Features of P4 LED display

To understand exactly how P4 LED displays are different from other types of LEDs, you must know its precise features.

High Definition

The P4 LED display has a high pixel density, capable of presenting detailed and clear images and text. It also has a higher contrast ratio owing to its high-quality SMD2121 LED which ensures the P4 LED sign has a high contrast rate and the video is clearer and showy. The P4 LED displays deliver stunning images with vivid colours and high contrast ratio.

Display Effect

The P4 LED display boasts a good display effect. It uses advanced display technology, it has good colour expression and wide viewing angle characteristics.

It offers a perfect visual effect with 62500 pixels density per square metre and 4mm pixel pitch making the P4mm LED screen image clearer and the layering stronger. The higher the density, the clearer the pixels.

Environmental Protection

The P4 LED display is energy saving because it uses LED as a light source. So, an LED brings the characteristics of low power consumption, long life and no pollution. The P4 LED screen uses high quality LED power supply to save your cost, and more to ensure the LED display continuously works.

Adaptability

The P4 LED panel can be customised according to customer needs, including

•  Size,
•  shape
• and installation method.

Wide viewing angle

The vertical and horizontal angles of view of the P4 LED display screen is very large. With horizontal/160° and Vertical/160° viewing angles, the vivid picture or video showing on the screen will hold your eyes from whichever different angle you view it. This means you can experience the same quality view from either side of the screen.

Light and slim design

P4 LED sign adopts aluminium material to ensure the display’s lightweight and thick nature, making it easy to handle and transport.

Easy installation and maintenance

The P4 LED display module is designed to ensure easy installation and maintenance.

The front or rear service access is available depending on your installation.So you can service the P4 LED displays from either the back or the front conveniently and easily.

Nevertheless, for permanent installations, it is easier to access it from the front.

Low Brightness and High Grayscale

Brightness can be adjustable. We can easily adjust the brightness of the P4 LED Panel screen to blend with the lighting of the surrounding. It can consistently maintain a strong viewing experience under low brightness status, even if reduced to 20% brightness.

Their brightness levels can attain values as high as 1000 cd/m².

The rate at which the P4 LED Screen refreshes is also optimised. This ensures that the displays we receive do not flicker and screen is not distorted

Extended Shelf Life

This type of screen can stay operational for around 12 years or even more if you carry out prompt maintenance. In as much as it is cost-friendly, it can provide you with a holistic and well-rounded complete service

What are the application scenarios of P4 LED Display?

You can see P4 LED displays in action in a variety of places, both indoors and outdoors. P4 LED displays can be divided into many types, mainly including the following:

1. Outdoor P4 LED display:A P4 LED wall is usually used in outdoor billboards, stadiums, performance stages and other scenes.
2. P4 rental LED display: P4 LED screen is mainly used for temporary activities, conferences, exhibitions and other occasions. P4 LED boards are better for large commercialities and businesses. Because it is lightweight, easy to install and easy to disassemble, it is convenient for users to quickly deploy and disassemble in different locations.
3. P4 sports stadium LED display: P4 LED panel is usually used in large sports venues, competition venues and other occasions.
4. P4 transparent LED display: This type of P4 LED display has the characteristics of high transparency, light weight, and space saving. It is usually used in shopping malls, showcases, stages and other places, and can realise various functions such as advertising display and background decoration.

Floor tile LED displays are usually made in large offices. These floor tile P4 LED walls can be configured with interactive sensors.

Life span factors of P4 LED display

The life of the P4 LED wall is affected by many factors. This list includes

• The quality of LED lamp beads,
• Production process,
• Usage environment, etc.

High-quality LED lamp beads and advanced production technology can ensure that the display has a long service life.

In addition, reasonable usage environment and maintenance measures are also primary factors in extending the life of the display.

P4 LED Display Auxiliary Equipment

P4 LED screen usually require some additional equipment to supplement its function, such as:

• Playback equipment: equipment like computers, players, etc.,  are used to transmit display content to the display screen.
• Control system: used to control the display content and effects of the display screen.
• Cooling equipment: such as fans, radiators, etc., are used to reduce the operating temperature of the display.

The bottom line

There are more and more types of P4 LED displays being introduced in recent times. P4 LED displays can better meet the application scenario standards of different LED displays for different customers. In this way, they are highly diversified and versatile in terms of use.

P4 LED displays ultimately seem to be the future of digital advertising.
