It seems like most screens look the same. They are flat, have a display resolution of 16:9, Full HD (1080p), black case and many inputs. There is, however, a significant difference between a public display monitor and a regular screen that you can buy in every shop with household appliances.
Public display monitors are built in such a way that they could last many hours of work in tough conditions (temperature, humidity).
No matter if you are an owner of a small neighborhood shop or a supermarket, you would like your monitors to display your offer without pauses and not to engage your employees.
Obviously, you may buy a cheap TV set for your shop, but there is a reason why companies use professional tools and not regular ones that are addressed to individual users. The advertising screen in your shop should not be an exception.
Radio and television license fee
Buying a standard TV set for your shop, you need to remember of paying the radio and television license fee. Every TV set is equipped with a DVB tuner, which allows for the reception of digital terrestrial television broadcast. According to the Radio and Television License Fee Act, the ownership of such a receiver itself is a requirement to pay to license fee. Bearing in mind that an advertising screen should be visible for as many people as possible, there is a huge possibility that it will be controlled, and what follows that, it will require payment.
Durability, work mode
Every shop is open at least 12-14 hours a day. No standard TV set will handle so many working hours. Therefore, how come two screens with matrices manufactured in the same technology (LCD) differ so much from each other?
That is above all due to the quality of materials used as well as different electronics and surrounding components responsible for cooling and burn-out protection.
Below you can find a photo of a regular LCD screen and a public LCD display monitor. The difference is visible even for a layperson.
1. Regular LCD screen
2. Professional LCD screen
In the example above you can notice that a professional LCD screen has fans and three bigger radiators. The regular TV set, on the other hand, is not equipped with fans and efficient cooling systems. It has only two small radiators.
After a few months a regular TV set working 14 hours a day will not fulfill its role. It means that the picture will be pale and barely visible or the screen will totally break down.
Another essential feature of public display monitors is the manufacturer’s warranty, which is 3 to 5 years. In case of a regular TV set, the warranty is 2 years.
What is important, if you use a regular TV set for professional purposes (12-24 working hours a day), the warranty will not be taken into account (even if the TV set is still under warranty).
It is due to a provision set forth in every regular TV user manual. A service point, after receiving a faulty device, sets a special mode, which gives them all information about the device and a history of its usage (how many times it was turned on/off and its working hours).
Or actually, the lack of service. From a device’s point of view, a professional advertising monitor, which was set up once is not going to engage the shop’s employees. A built-in schedule automatically manages the turn on/ turn off hours.
Regular TV sets in most cases have only a sleep timer, which you need to set each time after turning the screen off. A lot of amateur TV-based installations therefore require a manual set up.
In the initial phase of such installation’s functioning, the system is working, but later employees begin to ignore their tasks and a TV set which should show our offer turns into a black rectangle.
Summing up, let the screen work by itself and let the shop’s employees do tasks that require their presence.
Brightness, viewing angles
Is there any difference in the picture quality between a standard TV set and a public display monitor? In theory, there is not.
You might even say that standard TV models will display a given picture in a better quality than professional monitors. Here, however, we have two traps.
One of them is brightness of a screen. In a shop we have a different illumination (300-500 lx) than at home (200 lx). At home, when sunlight strikes your TV set, you cannot see anything.
The same happens in a shop, where bright light surrounding the screen prevents a good content visibility on a regular TV set. The situation is completely different with a professional monitor that generates much greater brightness and, because of that, will not be overshadowed by the shop’s illumination.
Another trap is a viewing angle parameter. We watch a standard TV set, facing it. Due to this fact, in such TV sets VA matrices are installed. They have a better blackness reproduction at the expense of viewing angles.
A monitor in a supermarket should be visible from all angles. Therefore, they use IPS matrices which allow for a lossless visibility even from 178o angle, maintaining blackness parameter at a satisfying level.
Obviously we can find also TV sets with IPS matrices, but they are much more expensive. Thus, it is better to buy a professional monitor with a range of other advantages.
1. Standard monitor
2. Professional advertising monitor
It is up to you
There is no denying that consumer electronics (including TV sets) are cheaper and cheaper, which may encourage a person unacquainted with the situation to buy a regular TV set for advertising purposes. This is somewhat understandable, since if a product A and a product B seem identical, why pay more for one of them?.
After, however, you learn more about their utility values, you will see why professional screens are more expensive. Taking into account their functionality, which results in a better efficiency of an advertising screen, freedom from maintenance and much greater durability, professional monitors prove to be a relatively cheaper solution.
