LED Display Screens Are “Priced Very Cheaply”, So What Should You Worry About?

Introducción

The price of pantallas led is temptingly low, but is it really cost-effective? Behind the cheapness, there may be a lot of “pitfalls” such as doubled electricity bills.

Frequent repairs, and no after-sales service. Do you still dare to place an order just by looking at the price?

Worry 1: The cost you see may be just the tip of the iceberg

The price is very low at the beginning, but the price may quietly rise in the later stages of installation, debugging, transportation, and accessories.

In order to grab orders, some merchants first lower the price of equipment very low, and then make money back through various additional fees.

Or even use some non-standard accessories, which is particularly troublesome for later maintenance.

The electricity bill is also a pitfall: cheap screens often use inefficient chips and power supplies, and the power consumption is amazingly high.

A normal screen may only cost a few cents for electricity per hour, but a cheap screen may directly double it. Over the years, the electricity bill will cost a lot more money.

There is also a bigger headache: cheap screens have a short life and break down easily. The lamp beads, driver chips, and power supplies used are of poor quality.

There are frequent malfunctions, such as dead lights, color differences, and module damage. Repairs are particularly troublesome, and the money spent may be more expensive than buying a screen.

In addition, the display effect of cheap screens is usually not very good. The brillo is not enough, the color is biased, and the refresh rate is low.

It is tiring to look at the eyes, especially the screens outdoors. The waterproof and dustproof level is not high enough. When it rains, it will short-circuit and be directly scrapped.

The most important thing is that many small manufacturers cannot keep up with the after-sales service.

If there is a problem, you can’t find anyone and can’t buy accessories. In the end, you can only admit that you are unlucky.

Therefore, when buying an LED screen, don’t just look at the cheap price. You must consider the quality, power consumption, maintenance cost, and after-sales service comprehensively. Don’t be greedy for small profits and suffer big losses.

Worry 2: Chips, power supplies, and lamp beads may all be the source of the problem.

Don’t look at the LED display screen. There are many “pitfalls” hidden inside. If there is a problem with key components such as chips, power supplies, and lamp beads, it will be troublesome.

Let’s talk about chips first. Some cheap screens use counterfeit goods or chips that have been eliminated long ago.

This chip has a poor display effect, blurry pictures, distorted colors, and is particularly uncomfortable to watch.

The failure rate is very high, and problems are prone to occur after a short period of use. For example, you may find black spots, color blocks, or flickering pictures on the screen.

These are mostly chip problems. Repairs are expensive and laborious, and may not be repaired.

Let’s look at the fuente de alimentación. If the power supply solution is unstable, it will be even more dangerous. The power supply is the “heart” of the entire screen.

Once it is unstable, the light will die, and the module will not light up. In severe cases, the board will be burned directly, and the entire screen will be useless.

And this kind of problem is often sudden. You may be fine the day before, and find that the screen is black the next day. Not to mention the high cost of repair, it also delays time and affects normal use.

And don’t underestimate these small things. If the brightness of the lamp beads is inconsistent.

The whole picture will look like a “big clown face”, with some places bright and some places dark, which seriously affects the uniformity and beauty of the picture.

And the problem of lamp beads is difficult to find. You may not notice it at the beginning, and only find that the picture is becoming more and more uneven after using the screen for a while.

Once this problem occurs, the lamp beads must be replaced, which is not cheap.

In short, when buying an LED screen, don’t just look at the price. The quality of these key components is the most important.

If you buy a screen with inferior chips, power supplies, and lamp beads, you will really spend money in vain and cause trouble for yourself. Don’t try to be cheap at the moment, or you will regret it in the end.

Worry 3: The control system is "shrinking"

The control system is the brain of the LED display. If it is “shrinking”, it will be troublesome.

The control cards used in some cheap screens have poor compatibility. Once connected to other devices, various problems will arise.

El frecuencia de actualización is low, and the picture looks like it is “climbing”. It is particularly stuck, especially when playing dynamic videos, and it is impossible to watch.

The response speed is also slow. You operate for a long time, and the screen does not respond for a long time, which is very frustrating.

Moreover, the control systems of many low-priced screens do not support remote management.

If the screen is hung high or far away, you have to climb up to operate every time you adjust the settings or update the content, which is extremely inefficient.

If you need to update information quickly in an emergency, you will be at a loss.

The most troublesome thing is that this “shrinking” control system is prone to failure. Stuttering, screen distortion, and black screen are commonplace.

Sometimes the screen is fine, but suddenly it goes black, or the picture is a mess, which is particularly troublesome to repair and may delay important activities.

Therefore, the control system is not a trivial matter. If you buy a “shrinking” one for cheap, you will really cause trouble for yourself. Don’t just look at whether the screen is bright or not; the key is whether the control system is easy to use.

Worry 4: How is the subsequent after-sales guarantee?

When buying an LED display, the after-sales guarantee is really important, otherwise it will be a “pitfall”.

Let’s talk about installation first. Some merchants find installation teams that are not professional at all, and the screen structure is unstable and shaky, which is particularly unsafe.

The wiring is also not standardized, and it is easy to have short circuits and poor contact problems, which will fail in a short time. If the screen is hung high and not installed firmly, it will be too dangerous.

Moreover, if the installation process is not done properly, the screen components may be damaged, and the repair will cost another sum of money.

Let’s look at after-sales maintenance. Some cheap screens have no one to take care of them when there is a problem.

When you call, the other party either shirks responsibility, or the repair cycle is very long, which makes you anxious.

Sometimes the screen is broken, and no one comes to repair it after waiting for more than half a month, which delays things a lot.

Moreover, the technical level of the maintenance personnel is also uneven. Not only may they not be able to repair it well, but they may also make it worse and worse.

The most frustrating thing is that many small manufacturers do not have formal warranty contracts at all.

If there is a problem, you want to hold them responsible, but they either can’t explain it clearly or directly shirk it, leaving you speechless.

Without contractual protection, your rights and interests are not protected at all. If you encounter a “disappeared” manufacturer, you can’t even find the person.

Therefore, when buying an LED display, you must ask clearly about the after-sales guarantee.

Professional installation team, timely maintenance service, formal warranty contract- none of these can be missing.

Otherwise, the screen will become a “decoration” after you buy it and use it. Don’t try to save money for a while, or you’ll regret it in the end.

Worry 5: Is there "cutting corners" in materials?

When buying LED display screens, the quality of materials must not be ignored; otherwise, it is easy to buy “defective products”.

Some screens are made of very thin materials and look light. The anti-corrosion and waterproof levels of such boxes are very low.

If used outdoors, the box will easily rust and deform when it rains or is slightly humid, and the components inside will also suffer.

Moreover, the thin box is also easy to damage during transportation or installation, and it will “lose its life” before it is used for a long time.

Let’s take a look at the PCB board, which is one of the core components of the screen.

The PCB boards of some cheap screens have chaotic routing, like a mess of tangled threads. This design can easily cause signal interference.

Once the signal is interfered with, the screen will flicker, flower screen, color deviation, and other problems, which are particularly uncomfortable to watch.

Moreover, the PCB board with chaotic routing is not good for heat dissipation, and it is easy to burn the board after a short time.

There is also a heat dissipation design, which is a big problem in summer. Some screens have a particularly rough heat dissipation design, too few heat dissipation holes, or poor quality heat sinks.

In summer, the screen will heat up seriously after a short time of use, which may cause freezing or crashes, or even burn the board. If you encounter hot weather, the screen may not be used at all, wasting money.

Therefore, when buying an LED display, you must carefully check the quality of the materials.

The cabinet should be strong, waterproof, and anti-corrosive, and the PCB board should have clear routing and good heat dissipation.

Don’t be fooled by the low price on the surface. The materials are “cut corners” and are troublesome to use. In the end, you still have to spend more money to repair or replace them.
