Making the screen bigger——LED video wall display

With the gradual growth in demand for seamless LED video walls from many businesses in recent years,according to relevant statistics, the value of the LED splicing video wall market has reached US$640 million in the first half of this year.

LED video wall display refers to a large or giant LED display made up of many display modules stitched together, which can cover the entire wall.

It is easy to see that this is a rapidly developing market. The market demand for huge LED displays is also growing, so we must follow the market orientation. The most popular and most in line with the user experience on the market now is the small-pitch LED display.

What is the fine pixel pitch LED display?

Fine pixel pitch LEDs refers to indoor display screens with LED dot pitches below P2.5.

Technology application:

Fine pixel pitch LEDs uses Point-control technology to control the brightness, colour reproduction and unity of the display pixel unit.

Manufacturing process:

All use automatic reflow soldering process in the production process,no need for manual post welding,which can save a part of human resource cost.

What is the competitiveness of the fine pixel pitch LED display?

1. Completely seamless splicing, small spacing, the good imaging effect

2. Natural and reality colour rendering

3. Point-by-point correction technology is mature, easy to operate and maintain.

4. The resolution per unit area is high, which is what many businesses look for and want to show the best results.


So judging from the technological breakthrough of fine pixel pitch LEDs, LED video wall displays can be spliced arbitrarily, and the size of the screen can be freely determined during the display process, giving the audience a better visual experience.

Any LED video wall display is made up of many LED modules, including naked-eye 3D video walls. For example :

MA640 modules

How to install an LED video wall LED display?

The first step is to choose a place for the LED display. Make sure there is enough space to place the LED display.
It is a simple step, considering where you will site the video wall.
The second step is to choose the right size modules.
There are different sizes of modules for you to choose from. Like in the case of the fine pixel pitch LED display there are the following:

The third step,ensure that the parts in the LED cabinet are complete.

Cabinet internals includes:

(1)Power supply,can be replaced in front
(2)Magnets,also can be replaced in front. If there is a breakage to be replaced in time.
Otherwise, it is easy to have imperfect articulation between the display and the display, affecting the overall look and feel.
(3)Control card,which is the rectangular parallelepiped in the middle.
The information can be saved when the power is turned off, and the stored information can be displayed without connecting to the PC.
(4)Connecting cable,it has a data cable, a transmission cable and a power cable, all of which should be connected at the same time when in use.

LED video wall application technology:

Control system:Novastar

With the maturity and widespread use of LED video wall technology,the system “Novastar” must also be kept up to date.

Novastar is a supplier of LED solutions to customers worldwide from Xi’an, China.

How exactly does Novastar control the video wall display?

First of all,the PC side of the control system “smartLCT”, the LED display controller and the LED display must be connected.

This means that the content of the video wall can be controlled from the computer, which is also more convenient for detection.

Secondly, SmartLCT supports the monitoring of video wall display data, reading back the program and configuration of the receiver card, support for LED display brightness adjustment and batch adjustment of cabinet brightness and chrome.

The LED video wall display can be checked in multiple ways. Then it’s a matter of uploading the content you want to show to the video wall via a data card, a process in which the Novastar control system plays an important role.

2. Indicator for the display to describe the colour - 18bit+.

18bit can express 2 to the 18th power or 262,144 colours, which is often referred to as 260,000 colours. 18bit+ allows for more accurate colour rendering on the display, with more subtle transitions between colours that do not appear abrupt.

3. Point-by-point calibration technique

This is a technology used to improve the brightness uniformity and colour fidelity of LED displays.

LED displays that are not calibrated may have problems such as displaying content that is not ideal and uneven heat distribution within the module.

So what benefits can point-by-point correction technology bring to an LED video wall?

  1. Real-time data updates through raw data collection.
  2. Divided into a holistic collection and sub-regional collection, which can develop solutions to specific problems.
  3. The links interact and work with the control system to achieve accurate data return.
  4. After correction maintenance, so that the screen to screen interface is more natural will not appear obvious dividing line.
