What are the advantages and disadvantages of LCD TVs?

Advantages: 1. Light, thin and portable, the weight of LCD TV is about 1 3 of traditional TV.

2. Rich colors, with millions of colors, the picture is layered, and the colors are gorgeous and real.

3. The resolution is large, the clarity is high, the gap of the liquid crystal itself is thicker, and the image is like a grid. So the best resolution of the LCD screen can generally reach 1024x768.

4. Low power consumption, long service life, according to industry standards, the use time of annual power consumption of hours per day, with 30-inch LCD TV instead of 32-inch picture tube TV, each unit can save 71 kilowatts of electricity per year. The lifespan of LCD TVs is generally 50,000 hours, which is much longer than the lifespan of ordinary TVs.

Disadvantages: 1. The display reflection is slow, and the response time of LCD is relatively long, so the performance in dynamic image is not ideal.

2. The display quality is poor, and the LCD can theoretically only display 18-bit color (about 262144 colors), but the color depth of CRT is almost infinite.

3. The viewing angle is small, and the viewing angle of LCD is relatively small compared to CRT display.

Advantages of LED LCD TV 1、Strong color gamut performance:The performance of traditional CCDL backlight LCD TV in color has always been criticized by people,But after the emergence of LED TV, this problem is expected to be fundamentally solved。 Unlike the constant illumination of condensing backlights, LED backlights can adjust the brightness of the lighting according to areas or even points, so there is a great improvement in contrast and color gamut.

2. Long service life: In addition to the color gamut, LED TVs also have another major feature, that is, long life. CCFL LCD TV condensing backlight manufacturers claim that it can reach 60,000 hours of life,In fact, most of the backlight groups cannot reach this life,Because a backlight group is composed of multiple lamps,As long as one is damaged,The TV cannot be normal**。

In addition, the attenuation of CCFL lamps is very high, about 7% per year, so even if it is not damaged, the brightness of the lamp will be significantly attenuated after 2-3 years. 3、Slim and fashionable appearance:Traditional CCFLLCD TV transmits white light,So you need to add a filter to achieve the purpose of color filter imaging,And RGB-LED is a three-color light direct irradiation,No filter is required,So the thickness of the TV can be further reduced,It can easily reach half the thickness of the traditional flat screen TV。

Disadvantages of LED LCD TV 1, LED LCD TV also has its own shortcomings. It's not as layered as it could be. In a dark scene,When showing the details of the scene,The layering shown by the LED TV is a little blurry,The depth of the picture is not obvious。

This is also a disadvantage of LCD TVs, which do not perform well in dark details. 2. In another important picture indicator - dynamic clarity. No matter how you change the backlight,LED is a kind of LCD TV after all,Therefore, the disadvantages of ordinary LCD TVs,The same appears on LED LCD TVs。

However, a series of compensation technologies such as 200Hz are constantly being upgraded, which can effectively reduce the delay of the picture. In addition, LED TVs use diode light-emitting technology, so they have a large amount of heat dissipation. LCD TVs are lighter and thinner than the earliest bulky TVs, and LED LCD TVs are also thinner than traditional LCD TVs, so people like thinner TVs, so LED LCD TVs are very popular.

There are two sides to any food, and the same is true for LED LCD TVs, which have advantages and disadvantages, and when people want to buy, they must be measured according to their actual situation.
