How can we avoid buying unqualified LED display screens?

Introduction

Among the dazzling array of products, how can we avoid those unqualified “pit goods” and choose a truly reliable display screen?

Don’t worry, this article will reveal the key points of purchasing Affichage LED screens for you, so that you can easily become a shopping expert!

1. What kind of LED display screen is unqualified?

1). The luminosité and power consumption are not right

Some LED display screens are not bright enough and cannot meet normal requirements.

For example, the brightness of indoor display screens should be between 800 and 1200cd/㎡m², but some of them are pitifully low in brightness and difficult to see.

Some display screens have uneven brightness, some places are dazzlingly bright, and some places are very dark. Moreover, some display screens are particularly power-consuming.

It doesn’t take long for the power consumption to be amazing; not only is the electricity bill high, but it is also easy to malfunction due to poor heat dissipation.

Some display screens will interfere with other electronic devices, and the surrounding things will “suffer”.

2). Poor display effect

Some LED display screens look very “terrible”.

First of all, the pixels are out of control, that is, some points are not lit or lit randomly, and black spots or bright spots will appear on the screen. The picture looks like a mosquito bite, and it is uncomfortable to watch.

The colour is also very bad. The colours are either not bright or look fake. The red is not red, and the green is not green.

Moreover, when you look at the screen from the side, the colour and brightness change greatly. If you turn the angle slightly, the picture will “change face”.

3). Unstable and unreliable

Some LED display screens “get angry” when they are used, flickering, freezing, or even crashing directly.

This is mostly due to the poor design or quality of the parts inside. Moreover, some display screens fail after a short time of use, and their lifespan is pitifully short. It is troublesome and expensive to repair them.

4). Many safety hazards

Some LED displays have poor fire resistance, and some unreliable manufacturers even use non-fireproof materials, which requires special attention!

Moisture and lightning protection capabilities are also poor. It is easy to break when it rains or the air is humid. It is even more nervous when thundering, and it may be struck by lightning.

5). Appearance and structure are not good

Some LED display screens do not look good, with scratches and deformation on the screen, and the colours do not match.

The structure is not strong; it will loosen with a slight touch, and it is not stable when installed, and it may fall apart during use.

2. What are the channels for purchasing LED display screens?

1). LED display screen supplier

Purchasing directly from professional LED display screen suppliers is the most common way.

These suppliers are usually manufacturers, who can provide the latest and most complete product models, with guaranteed quality, and can customize products according to needs.

However, purchasing directly from suppliers may require a certain purchase volume, which is suitable for enterprises or customers with large needs.

2). LED display screen agent

Agents are an important bridge connecting suppliers and consumers. They usually cooperate with multiple suppliers to provide LED display screens of various brands and models.

Purchasing through agents can enjoy more flexible procurement policies and more convenient after-sales services, and agents can often provide more competitive prices.

For ordinary users or small and medium-sized purchases, this is a very suitable choice.

3). Resale

The resale channel mainly refers to buying LED display screens from the second-hand market or individual sellers.

The advantage of this method is that the price is relatively low, but the disadvantages are also obvious, such as the product quality is difficult to guarantee, and there is no formal after-sales service.

If you choose this method, you must carefully check the quality and performance of the product, and it is best to find a professional to help identify it.

3. How can the quality problems of LED display screens be distinguished?

1). See if the screen is flat

You have to look at the screen carefully. If the screen is not flat, it is definitely not a good product. Touch the screen gently with your hand.

A good screen should feel flat and will not have the feeling of potholes.

If there are obvious bulges or depressions on the surface of the screen, it means that the quality is not up to standard.

When using this kind of screen, the picture may be deformed and look particularly uncomfortable.

2). Try the display effect

The display effect is the key. You have to try whether the screen is bright and the colour is correct.

Look at the screen under natural light and indoor light. If the brightness is not enough or the colour looks particularly dim, it is definitely not good.

You can try playing a colourful video, such as a colourful cartoon, to see if the colours on the screen are as bright as in the video.

If the colors look strange or there is a noticeable color difference, it means that the color reproduction of the screen is not good.

Also, you have to look at the screen from the side. If the colour and brightness change greatly when viewed from the side, it means that the viewing angle is not good, and the screen is very limited for use.

3). Try it out

Practically try it out. This is the most direct way. Play a long video, such as a movie of about an hour, to see if the screen flickers, freezes or freezes.

If these problems occur after using the screen for a while, it is definitely not stable.

In addition, you can also touch the back of the screen with your hand. If it feels very hot, it means that the heat dissipation is not good.

Screens with poor heat dissipation are prone to problems after long-term use, and their lifespan will be shortened.

4). Look at the details

Details can also reveal many problems. Look at the power cord and signal cable. If the cable is very thin and feels hard, it is definitely not good.

Good wires should be thicker and softer, and the surface should be smooth with clear markings. Look at the solder joints again.

Good solder joints should be full and smooth, without cold solder joints or leaks.

If the solder joints look bumpy, it means that the craftsmanship is not good, and this kind of screen is prone to problems after long-term use.

5). Ask after-sales

After-sales service is very important. You have to ask the merchant how long the warranty period is.

Generally, the warranty period of LED display screens of regular brands is 1-3 years. If the warranty period is particularly short, it is definitely not reliable.

You can also ask if there are many after-sales service outlets. If there are few after-sales outlets, it will definitely be troublesome to repair if there is a problem.

It is also important to understand the specific process of after-sales service, such as maintenance response time, maintenance costs, etc., which can help you judge whether the merchant is reliable.

6). Compare prices

Price is also a very important reference factor. If you see a particularly low price, you have to be careful, and maybe there is a problem with the quality.

You can compare several more to see which one has a high cost performance. If the price is significantly lower than the market price, it may be because the screen quality is not up to standard or there are other risks.

Don’t be tempted by low prices and end up buying poor-quality products, which will be a big loss.

With these few tricks, you can basically see the quality of the LED display. Don’t be fooled by the surface!
