Your Guide to Pixel Pitch & LED Walls

In an LED wall, each individual LED is one pixel. The pixel pitch number indicates the distance between LEDs on the wall (in millimeters), which determines a recommendation of a minimum distance that a viewer should be to see the image as intended. The lower the pixel pitch, the closer together the LEDs are on your display, and the closer your acceptable viewing distance can be. The optimal viewing distance is typically 2-3 times the pixel pitch number in meters. For example, narrow pixel pitch of 2 would allow viewing from just 4 meters away, whereas a pixel pitch of 10 would require at least a distance of 20 meters to experience optimal detail. Pixel pitch affects both viewing distance and perceived visual performance of LED displays.

How to Choose Suitable Brightness for LED Screen Display?

Brightness is an important technical parameter to measure LED displays. The manufacturer or supplier of LED screen displays always asks you what maximum brightness will you want for your LED screen. But many people don't know it well, all think that the higher brightness is better.

Actually, the suitable brightness is the best one. Otherwise, if the brightness is too high, the energy consumption will increase, and if the brightness is too low, the contents of the LED screen display cannot be seen in bright sunlight.

To choose the suitable brightness for an LED screen display, you should consider the following factors:

1. Environment:

The brightness of the LED screen should match the ambient light of the environment in which it is placed.

If you are looking for more details, kindly visit Professional Video Conferencing Equipment.

2. Distance:

The brightness of the LED screen should depend on the viewing distance. For example, if the LED screen is placed farther away, a higher brightness level is required.

3. Content:

The brightness also depends on the type of content to be displayed on the LED screen. For example, if it is a video or image with dark colors, a higher brightness level is needed.

4. Duration of Use:

If the LED screen is going to be used for a long time, it is better to choose a lower brightness level to avoid eye strain and improve energy efficiency.

5. Cost of LED Screen:

Higher brightness levels require more energy, which may increase the cost of running the LED screen display.

Overall, it is recommended to choose a brightness level that provides clear visibility and optimal viewing experience in the given environment.

Compared with outdoor LED display, the brightness of indoor LED display can be slightly lower, mainly depending on its actual use scene.

If it is installed by the window for external playback, the brightness needs to be above 2500cd/m2;

If it is installed on the side of the window and plays inward, the brightness needs to be around 2000cd/m2;

The brightness of indoor LED displays installed in general shopping malls needs to be around 1000cd/m2;

The brightness of the LED display in the conference room only needs to be 300cd/m2~600cd/m2.

What are the Types of LED Display Screens?

LED display screens are a popular and versatile solution for a range of applications, from advertising to information display. There are several types of LED display screens available to suit different needs.

Indoor LED Screen vs. Outdoor LED Screen

One commonly used type is the indoor LED display screen, which is primarily designed for use in indoor environments. These screens are typically mounted on walls or suspended from ceilings and are often used for advertising, entertainment, or information display. They are high-resolution and offer excellent image quality even in low-light environments.

Outdoor LED display screens are another popular type, designed for use in outdoor environments. These screens are usually larger than indoor screens and can withstand elements, including rain, snow, and wind. They are commonly used for advertising, sports events, and concerts, and can be seen from long distances due to their brightness.

Indoor LED screens and outdoor LED screens differ in several aspects:

1. Brightness: 

Outdoor LED screens are generally brighter than indoor LED screens to provide better viewing under direct sunlight.

2. Resolution: 

Indoor LED screens have a higher pixel density and a better resolution compared to outdoor LED screens.

3. Size: 

Outdoor LED screens are generally larger in size compared to indoor LED screens.

4. Weather Proofing: 

Outdoor LED screens require weatherproofing to protect them from rain, wind, and other environmental factors. Indoor LED screens, on the other hand, are not exposed to these external factors and do not require weatherproofing.

5. Viewing angle: 

Outdoor LED screens have a wider viewing angle as they are designed to be viewed from a distance, while indoor LED screens have a narrower viewing angle.

6. Power Consumption: 

Outdoor LED screens consume more power compared to indoor LED screens due to the higher brightness and larger size.

7. Cost: 

Outdoor LED screens are typically more expensive compared to indoor LED screens due to their extra features and durability.

Fixed LED Screens vs. Rental LED Screens

The main difference between fixed LED screens and rental LED screens is their installation method.

Fixed LED screens are permanently installed in a designated location.

Rental LED screens are designed to be easily transported and set up for temporary events.

Front Maintain LED Screen vs. Rear Serviceable LED Screen

A front-maintain LED screen refers to an LED display that can be serviced and maintained from the front side, meaning technicians can easily access components, LED modules, LED power supply, and LED cabinets from the front of the LED screen without the need to go behind the LED screen.

On the other hand, a rear-serviceable LED screen means that technicians need to access the LED screen components from the backside of the LED display and open the door of the LED cabinet to carry out maintenance.

The main advantage of front-maintain LED displays is that they require less space for installation and maintenance since there's no need for rear access. This makes them ideal for indoor installations, tight or limited spaces where access is limited.

In addition, front-maintain LED screens have a more streamlined design since they don't require a service passage, making them more aesthetically pleasing.

Rear-serviceable LED screens are ideal for outdoor installations that are placed on high billboards, wall buildings, and top roofs where space is not a constraint. They also come in handy when rear access is preferred or required for maintenance or repair.

Overall, the choice between front-maintain LED screens and rear-serviceable LED screens will depend on the specific needs and space constraints of your installation.

Of course, the cost of Front Maintain LED Screen is more expensive than Rear Serviceable LED Screen.

Synchronous LED Control System vs. Asynchronous LED Control System

When choosing the control system for an LED display, it is essential to analyze the specific application requirements of the project and budget constraints.

There are two main types of control systems: synchronous and asynchronous.

In  short words:

LED Screen Display Synchronous Control System  -  Change the content of  images or videos  on-site with an on-site computer.

LED Screen Display Asynchronous Control System - Change the content of images or videos remotely with an anywhere computer via the internet.

Based on the pixel resolution of the LED Screen Display and the load capacity of the LED Screen Display controller, which LED Screen Display control system is to be used?

Indoor LED Screen Display uses a Synchronous control system while Outdoor LED Screen uses an Asynchronous control system.

LED Screen Displays with Larger pixels resolution use Synchronous systems while LED Screen Displays with Smaller pixels resolution use Asynchronous systems.

Here's a brief comparison between these two types of control systems:

Synchronous LED Control System:

This type of control system requires continuous communication between the display and the controller via ethernet cables or wireless networks. The content that needs to be displayed is processed by the controller and then transmitted to the display in real-time.

Synchronous LED controllers require a video source that is always connected to the LED screen. This could be a media player, a PC, a video camera, or even a computer games console, basically anything with a video source output.  It relies on a continuous connection to a video source that can output through HDMI, DVI, Display Port, or CVBS. In situations where the output image does not match the aspect ratio of the LED screen, video scalers can be used to adjust the image size. Additionally, video scalers can also combine multiple sources to create a larger image or split sources into sections using picture-in-picture (PIP) functionality.

Synchronous systems allow real-time editing and updating of the displayed content. These systems are ideal for live events, advertising, and any application in which the content needs to be updated regularly. A synchronous system requires a constant connection between the display and the controlling device, such as a computer or video processor.

Synchronous systems are suitable for applications where the content needs to be changed frequently and the display is located inside a static environment, such as an indoor shopping mall, stadium, or concert hall.

Asynchronous LED Control System:

This type of control system uses a multimedia player or memory card to pre-store the content and then sends the pre-generated content to the display unit.

Asynchronous systems are self-contained, meaning they do not require a continuous connection to the LED controller and are suitable for applications where the content is static or does not require frequent updates, such as advertisements or public information displays placed on the side of the road.

Asynchronous systems, on the other hand, allow pre-programming of the content to be displayed. These systems are typically used for information displays, such as in transportation hubs, shopping centers, or public venues where the information does not need to be updated frequently.

An asynchronous system does not require a constant connection between the display and the controlling device, it also can be remote to upload the content by connection methods vary but can include WIFI, USB, and ethernet, and some of the latest models even include 4g or 5g network connections. That means the system is more flexible than synchronous systems.

The choice between synchronous and asynchronous systems depends on the specific needs of the application. For applications where speed and accuracy are critical, such as sports events or concerts, a synchronous system may be the best choice. For applications where ease of use and independence are important, such as outdoor advertising or information displays, an asynchronous system may be more suitable.
