Hello, everyone. Lin Fei has come to answer the above questions. Which is better, oled TV or led TV? many people do not know the difference between lcd TV and led TV. Now let's take a look.

The difference between LCD TV and LED TV [picture and text tutorial]

Some friends insist on which is better, LCD TV or LED TV? What's the difference between LED TV and LCD TV? Here is the difference between LED TV and LCD TV. Let's have a look.

Introduction of LCD TV and LED TV

LCD TV, as its name implies, is a TV with LCD screen. Liquid crystal display, or LCD for short. The world's first liquid crystal display device appeared in the early 1970s, it is called TN-LCD (twisted nematic) liquid crystal display. Although it is monochromatic display, it has been widely used in electronic watches, calculators and other fields.

In the 1980s, STN-LCD (super twisted nematic) liquid crystal display (LCD) appeared, and TFT-LCD (thin film transistor) liquid crystal display technology has been developed, but the liquid crystal technology is not mature and difficult to popularize. In the late 1980s and early 1990s, Japan mastered the production technology of STN-LCD and TFT-LCD, and the liquid crystal industry began to develop at a high speed.

Today, LCD TV has been popular all over the world, especially LED LCD TV has shone brilliantly in recent years. Strictly speaking, LED TV refers to the TV set with LED (light emitting diode) as the display device, which is generally used for low-precision display or outdoor large screen.

At present, the strict name of LED LCD TV sold in the home appliance industry on the market is "LED backlight LCD TV". It uses LED light source to replace the traditional fluorescent tube, which has better picture quality, longer theoretical life, more environmentally friendly manufacturing process and thinner LCD panel.

The difference between LED TV and LCD TV

LED TV has five advantages:

First, ultra-wide color gamut, can reach the 105%NTSE color gamut, the color is more bright.

Second, ultra-thin appearance, the thinnest up to 1.99cm, more fashionable.

Third, energy saving and environmental protection, energy consumption is 52% lower than cold cathode backlight, there is no mercury pollution of cold cathode tube.

4. The service life is long, reaching nearly 100000 hours. If you drive 10 hours a day, you can use it for 27 years.

5. It can achieve ultra-high contrast and higher definition of 10000033601.

The above performance advantages determine that LED backlight is technically a substitute for cold cathode backlight. At present, the market price is almost half as expensive as the cold cathode backlight. The backlight itself has no choice. The choice of the whole machine is mainly the technical performance parameters of the LCD panel, such as the maximum physical resolution, dynamic response time, etc., which is the same as the ordinary LCD TV.

Advantages of LCD TV:

1. In appearance, the body of LCD TV is slimmer, especially the latest LED backlit TV, which is even less thick than 1cm.

two。 LCD TV consumes less power and is more power-efficient than plasma TV of the same size.

3. LCD TV has high brightness, and the picture quality will not change much in a bright environment, but it is still gorgeous. For still pictures, LCD TVs are also more clear and delicate.

Disadvantages of LCD:

1. The dynamic definition of LCD TV is not high, mainly because the deflection speed of LCD molecules is limited, so LCD TV will appear the phenomenon of tailing.

two。 LCD TVs have more or less light leakage, especially in an all-black environment. Because of the problem of light leakage, the black of LCD TV is not deep enough, the contrast of plasma TV is not high enough, and the sense of picture hierarchy is not strong enough.

LCD TV is characterized by beautiful appearance, low power consumption, more power saving and high brightness, but it also has some shortcomings such as low dynamic definition, light leakage, lack of black expression, low contrast and so on.

That's the difference between LED TV and LCD TV. You can refer to the above data when choosing.

Understand: LCD TV. Is the hard screen better or the soft screen better?

LG ultra-thin TV release! The thickness of the new ultra-thin TV display panel has been reduced by 75%.
