How to choose an LED TV? What is different about LED LCD TVs

Whether it's an LCD LCD TV, or an LED backlight LCD TV, the panel has always been the core of both.

LCD TV experts revealed: "Look at the panel first, and then compare the backlight."

It seems that you are very rich, and since you have money, you don't have to think too much about finding expensive new ones to buy.

LED backlight LCD TV is best to have RGB three-color backlight Now most of them, In China, the vast majority (into 9) are white backlight + dynamic backlight display, and the previous CCFL LCD picture quality is not very much improved. If it's an RGB backlight, the color will be a little better, anyway, if you have money, you can buy it.

I think Hisense's is good, 42 inches, 12,002 3 can come down.

Now there is no real LED TV, but an LCD TV with LED backlight. LCD TV is still the most important panel,Hard screen is better,Followed by backlight,LEDThe backlight is divided into side light type and direct type,Side light type can make the TV thinner,Direct TV effect is better。

SamsungLED TV has the advantage of brilliant colors, mainly referring to the color gamut coverage of LED light sources. The traditional CCFL backlight emits light by excitation phosphor, and its luminescence spectrum has many residual components and low color purity, resulting in a small color gamut, usually only about 70 color gamut coverage. The LED backlight has a narrow luminous spectrum, good color purity, good color gamut coverage and color reproduction, so it is more gorgeous in color performance.

screen. And it's not good for side lighting.

Or buy a joint venture.

Matrix backlight is good.

But the only drawback is that RM and RMVB formats are not supported.

But buying LED is still important to choose the screen.

Friends, the choice of LED LCD TV should pay attention to 1, the appearance of the atmosphere, 2, the audio-visual effect is good (including color, picture quality), 3, the screen is good, 4, the after-sales service is good, 5, foreign brands (at present, foreign brands are better than domestic brands); It is recommended to buy before the Spring Festival, and the brand is Toshiba's flagship SV650.

The most direct link to the quality of the picture is this panel,I often hear friends around me talk about TVs with such a hard screen panel,Better picture quality,I know a few brands of Hisense、LG's can be。

Now many people think that there is no experience in choosing LED TV,In fact, it is very simple,The quality of LED TV lies in the panel,As long as you can distinguish the panel,Now the best sales should beIPSIlter screen panelLEDTV,Quality is king!

Apple's ipad tablet,It's an IPS hard screen panel,Multi-touch,It's very good,

LED LCD TV is a technology that uses light-emitting diode technology to imaging, and there is a little problem with color reproduction at present, and the new technology is being applied to TV imaging technology.

LCD is an LCD TV, and LED is a breeding of the light source used in LCD TV. It's like the difference between a gasoline engine and a diesel engine inside a car. It's not all right, but it's pretty much the same.

LEDs are more energy-efficient and more durable than older tube light sources. Because if the lamp is broken, it is very troublesome to repair. LCD TVs or monitors rely on light sources (old tubes or new LED LEDs).

To understand simply: you can understand the old-fashioned as using fluorescent lamps as the light source, and the new ones use the LED flashlights used by many flashlights as the light source.

Now there are LED flashlights sold everywhere, have you always seen or had? Herein lies the difference. If the same battery is illuminated with a teacher's bulb, the time is much shorter than with LED lighting.

Therefore, this is the reason used for LCD TVs, and it is easy to break down if the energy consumption of old-fashioned lamps is too large. The use of light-emitting diodes (LEDs) consumes less energy and is not easy to damage).

The most important thing is, will you feel the temperature when you turn on your LED flashlight for a few hours when you touch it? No, it won't. And the general bulb flashlight, fluorescent lamp, after a long time of running, your hands will feel hot to the touch.

The increase in heat also leads to the acceleration of the aging and damage of other parts in the surrounding area.

This heat is the same as the computer, and it makes sense that when you use the computer to see that the temperature of the graphics card runs to nearly 100 degrees Celsius when you play games, you will worry about the graphics card burning out or something.

Electronic components are sensitive to heat, so they need to dissipate heat. For any part, heat can lead to premature aging. Therefore, the CPU of the computer should be equipped with a fan, and if the temperature reaches about 98 degrees, the computer will automatically shut down and cool down, otherwise the CPU will burn out.

The reason is here,LED(light-emitting diode)When it is used as the light source of LED LCD TV, the heat emitted is less than that of the old-fashioned lamp,It directly reduces the heat suitable for the overall TV work, and naturally prolongs the service life。

If you don't understand, you compare an LCD TV with a CRT TV, and an LCD monitor with a CRT (old-fashioned bulky display) monitor. Which one is cooler when used?

LCD TV is LCD, you must use a light source, the old LCD is to use a cathode high-voltage fluorescent lamp as a backlight, and now the LED used by LCD is a backlight source, which is to save electricity. As for LCD TVs and LEDs, there is no difference, it's just that the light source is different.

Refer to someone else's.

LED refers to light emitting diode, and when we say LED, we mean a liquid crystal display that uses a light emitting diode as a light source.

LCD stands for Liquid Crystal Display, which uses CCFL (Cold Cathode Fluorescent Lamp) as the light source. They use different backlights.

Compared with LCD with LED as the backlight source, the biggest advantage of LCD LCD panel using CCFL (cold cathode fluorescent lamp) as the light source is mainly reflected in the following three aspects:

First, the thickness of LCD with LED backlight will be further reduced.

The thickness of the LED screen notebook panel is about 1 2 of the thickness of an ordinary CCFL screen.

Second, it has a longer life, lower power consumption, and is more environmentally friendly.

LEDs have a lifespan of up to 100,000 hours and can be used for 27 years even if they are used continuously for 10 hours a day. After using the LED backlight system, the energy consumption can be greatly reduced, and it saves 48% of electricity compared with the commonly used CCFL LCD screens. Moreover, the LED does not use mercury, an element that is harmful to the environment, which is quite environmentally friendly, while CCFL contains mercury.

3. The color expression of the LED backlight screen is far better than that of CCFL.

The original CCFL backlight did not perform well in terms of color levels due to color purity and other problems, resulting in LCD being inferior to CRT in terms of grayscale and color transition. According to the test, the CCFL backlight can only achieve 78% of the NTSC color area, while the LED backlight can easily obtain 100% of the NTSC color area. LED backlights also have significant advantages when it comes to color expression and gradation transitions.

There are two kinds of LCD TVs, one is LCD and the other is LED. The LED TV picture is relatively clear and bright, the body is thinner, and the LED TV uses a cold light source, and the TV generates less heat, which is more energy-saving and power-saving. LCDThe picture of TV is also good, but the fuselage is a little thicker than LED TV, but it is not a cold light source, and there is no LED TV energy saving.

LCD technology is more mature, the performance is relatively stable, LED TV adopts new technology, and the quality is still good. I recommend buying Hisense's LED, because it is the first manufacturer in China to make LED TVs, and the technology and production process are in a leading position in China. That's just my personal opinion.

LCD liquid crystal display, the structure of the LCD is to place liquid crystals in two parallel glasses, and there are many vertical and horizontal thin wires between the two glasses, which control the direction of the rod-shaped crystal molecules by whether they are energized or not, and the light is refracted to produce a picture.

LED light-emitting diodes.

The so-called LED TVs on the market at present... In fact, it is still LCD, but the backlight uses LED to emit light, and LED has the advantage of low power consumption and low heat.

An LCD TV and an LED TV are the same thing. The so-called LED refers to the backlight of the LCD TV. Except for full-color LED screens.
