How to use LCD TV is better?

With the development of science and technology and the continuous updating of smart products, television has also entered the era of LCD. LCD TVs have become an essential entertainment center for every family. The biggest difference from CRT TVs is the use of screens. So how can LCD TVs be used better? What issues need to pay attention to in daily care? Bringing LCD TV tips, detailed analysis of the three major drawbacks of daily care.

What is the difference between LCD TVs and CRT TVs? First, the LCD TV screen is not glass, ordinary LCD TV screen surface is a plastic material polarizer, hard-screen surface is an additional layer of resin Bale, compared to the CRT TV surface glass to be more fragile. And the imaging principle of LCD TVs is also very different from traditional CRT TVs, and there are many differences in use and protection.

Of course, the development speed of TV is very fast now. New standards such as 4K and smart are constantly emerging, and the speed of television replacement will be accelerated. However, the use of a LCD TV for 5 years is certainly not a problem. So how can we effectively protect our smart TVs in the past few years has maintained a clear picture and excellent performance? In fact, we only need to pay attention to correcting the way we can protect LCD TVs. Below, the author will take stock of the errors that we have in the use of LCD TVs.

Misunderstanding 1: Use screensaver when the screen is paused

I believe that all the friends in the use of computer screen protection have been exposed to this feature, in the past when using CRT monitors, Windows often set a screen saver by default. As the name implies, the function of the screen saver is to protect the computer and the TV screen because the imaging principle of the CRT TV is that the electron gun emits an electron beam by the internal electron gun. When the electron beam hits the inside of the screen surface, the luminescent paint inside the screen is hit by the electron beam. Glow produces an image. If the same internal compatibility is displayed for a long time, the screen surface will be overheated, causing the screen to deteriorate and reducing the service life of the television. Therefore, the screen saver prevents the screen from overheating and damage by allowing the screen to display constantly changing images.

And now that the LCD TV is paused when playing local resources, or if the smart operating system stays in a certain interface for a long time, it will enter the screen saver system, but in fact this setting is wrong.

The imaging principle of the liquid crystal television is that light is emitted from the backlight source, which is regularly refracted through the liquid crystal panel and displayed on the screen through the filtering of the second filter layer. In the imaging process, there is no such high heat as the CRT TV electron beam strikes. Generally, no screen damage will occur. And the screen saver makes the constantly changing images displayed on the screen add burden to the LCD TV and accelerate the aging of the TV. Therefore, when we are using LCD TVs, we should turn off the screen saver program for TVs. You can leave them for a short time and you will need to remember to turn off your TV when you leave for a long time.

Misunderstanding 2: Do not clean the TV for a long time

Traditional CRT TVs suffer from electron beam impact on the inside of the screen and carry static electricity, which absorbs a large amount of dust and causes the TV screen to be very dirty. In contrast, the imaging principle of LCD TVs is very different from that of CRT TVs. There is not so much static electricity on the screen. However, this does not mean that the screen of the LCD TV is not dirty. Although there is no obvious static electricity, there will still be some static electricity, and the surface of the LCD TV screen is not smooth, which will cause the screen surface to have a layer of dust attached to it.

The existence of dust will bring many problems. The first is the impact on the quality of the picture. The original high-glossy screen was covered with a layer of dust, which could seriously affect the passage of the screen light, causing the screen to be dark and lacking in brightness. Second, dust on the screen will increase the harm of TV radiation to the human body. Dust is an important carrier of electric radiation. Even if you turn off the TV, dust attached to the TV will retain part of the electromagnetic radiation and cause lasting damage to the human body. Finally, dust adheres to the screen or even inside the TV. This can cause the board, components, and screens to dissipate heat, increase power consumption, and even burn out electronic components.

Therefore, the TV screen needs to be cleared in time to prevent dust from accumulating. Knowing that you sweep away dust not only reduces the burden on the TV, but also sweeps away the radiation inside the dust. In addition, after the TV is used, it should wait for the TV temperature to drop to near room temperature, and then cover with a protective cover. This will not only allow the TV unit to dissipate heat in time, extend its lifespan, but also prevent dust from attacking.

Myth 3: Spray water or use alcohol to wipe the screen

Some people wipe the TV screen and they are used to spraying water or cleaning liquid onto the screen, and then wipe it with glasses cloth or TV cleaning cloth. But in fact this is very dangerous. The borders of the TV screens often cannot achieve the waterproof effect. Water is sprayed on the screen or the body. It is very easy to enter the TV from the edge of the screen and the cooling holes. When you turn on the TV, it will cause the short circuit of the TV and burn it. Bad TV components.

Others are accustomed to wiping screens with disinfectant chemicals such as alcohol, which is even more unacceptable. The screen surface of LCD TVs is made of organic plastic polarizers, and most of them are coated with special coatings. However, alcohol is an organic solvent and can directly damage the coating on the screen surface. The television will suffer from deterioration of the picture quality due to the damage of the coating, and the screen will be unclear.

The correct way to clean TV is to divide it into two parts: screen and body. For the screen, strictly speaking, it is necessary to spray a suitable amount of ion-free water with a special liquid crystal wipe, so that the wipes have a slight dampness, and then wipe it again. But it seems to be less necessary for the average family. In fact, when dealing with a more general TV, wipe it gently with a wet eyeglass cloth or lens cloth to clean the screen with less damage to the TV. For the TV body, there is not so much stress. Just use a soft, slightly moist wipe, being careful not to allow liquid to enter through the vents.

Saying that buying a good TV is like choosing a friend who can communicate. If you don't want to make your friend "sick," then please protect it.
