Can LED TVs replace LCD TVs?

It will be replaced, it's just a conceptual error, in fact, LED or LCD TV, but the backlight is different, it uses a new LED emitter, which has a longer life than the original cold cathode fluorescent lamp (CCFL), tens of thousands of hours are not too attenuated, the luminous efficiency is very high, it is very power-saving and durable, and the color reproduction is better than that of cold cathode fluorescent lamps (CCFL.

Can't replace **Too expensive LED TV is just an LED backlight LCD or LCD TV It's just that you were fooled by Samsung, which is equivalent to a range hood with a fan inside It means the same.

It's good that someone cares about this. In general, it is better to use LCD for small screens, and LED for large screens.

The LCD principle is to integrate a large number of components on a piece of glass to form a large composite integrated block, the cost is naturally very high, and at the same time, due to too many secondary integrated components, it is easy to fail and cannot be repaired, which is the reason for the bad pixels of LCD; In addition, due to the limitation of glass strength, large-screen LCD has a maximum size limit, which is difficult to increase.

The principle of LED screen is to use LED diodes to emit light, which also requires the integration of a large number of components (the number is much larger than LCD), and the cost is higher, but any damaged LED can be replaced; Since LEDs do not need to be mounted on transparent glass, there is no size limit. The main problem is that the current plastic LEDs that do displays do not have a lifespan.

Long enough, it needs to be improved.

LED LCD is two different concepts of TV that do not have the problem of replacing or not replaceing.

See references for details.

It can't be done in a short period of time, and only a small part of it can be accepted.

The real LED TV will be on the market next year, and the time is not right to buy it now.

is an eternal theme.

The led screen is good.

1、Whether it is LED TV or LCD TV,Their screens themselves are LCD(liquid crystal),Real LED display is difficult to use in the field of home Huihui TV,Because its pixels are too large,It is difficult to miniaturize in the case of high resolution。

2. In the TV industry, LCD TVs are divided into LED TVs (using LED backlight modules to provide light sources for the screen) and traditional LCD TVs (using CCFL cold cathode fluorescent tubes as light sources) due to different backlight systems.

3. In contrast, LED can be easily adjusted in the area (the problem of LCD light leakage can be answered to a certain extent, but it can only be alleviated, and it is almost impossible to reach the contrast of the traditional CRT picture tube TV in theory), and the life is longer (the CCFL tube will appear to decrease in brightness or start difficult after working for a few years, and it needs to be replaced.)

4. Although the cost of CCFL is not high, only about 10 yuan, the maintenance personnel will definitely open a very high price to help you change), the working voltage is lower (LED can work at 2V 4V, and the CCFL tube needs a high voltage of nearly 1200V to start, so it is necessary to use a special inverter circuit to provide high voltage.

TV screen LED is better than LCD.

LED TV is actually LCD TV, that is, a kind of LCD TV, it is different from traditional LCD TV mainly in that it uses different backlights, which brings many differences in performance. The LED light source replaces the traditional fluorescent tube, the picture is better, the theoretical life is longer, the production process is more environmentally friendly, and the LCD panel can be thinner. So does it mean that LCD TVs are going to be eliminated?

It is a display method that controls semiconductor light-emitting diodes, which are roughly like a number of light-emitting diodes, usually red, that display characters by turning lights on and off. The display screen used to display various information such as text, graphics, images, animations, **, video signals, etc., while the LCD TV screen cannot meet this requirement, so the LED is good.

The visual experience of LED Huai Burn is good.

For LEDTV,First of all, it is ultra-thin,After that, it is more low-energy-saving and environmentally friendly,And there are no toxic substances inside,But the file family, but LEDTV's backlight, brightness, color reproduction, are relatively close to reality,Therefore, it can give people a very good visual experience。 <>

"LED LCD TV" is the hottest word in the TV market at present, compared with the CCFL backlight used in ordinary LCD TVs, LED LCD TVs are more energy-saving and environmentally friendly, and have a longer service life. LED LCD TVs are divided into two types: side-emitting and direct-illuminated, of which side-emitting LEDs are light and thin, while direct-emitting LEDs can achieve better color uniformity. Because the side-emitting LED backlight LCD TV has an ultra-light and ultra-thin appearance, it is popular with more and more consumers!

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.

The average life of CCFL backlight is 2-30,000 hours, while the average life of LED can reach 5-60,000 hours, and the life of high-quality LED backlight can even reach 100,000 hours, which is similar to the life of LCD panels, saving the trouble of replacing the backlight. This is also one of the main advantages of LEDs.

Of course, nothing is perfect, and LED LCD TVs have their 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.

Another important image metric is dynamic sharpness. 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 is a liquid crystal panel, and the LED now refers to the liquid crystal panel that uses light-emitting diodes as the backlight. The LED backlight has five advantages over the traditional cold cathode fluorescent tube backlight: First, the ultra-wide color gamut can reach 105% of the NTSE color gamut, so the color is more vivid.

Second, ultra-thin appearance, the thinnest reaches centimeters, which is more fashionable. 3. Energy saving and environmental protection, energy consumption is 52% lower than that of cold cathode backlight, and there is no mercury pollution of cold cathode tube. Fourth, the life is long, reaching nearly 100,000 hours, and it can be used for 27 years if it is driven for 10 hours a day.

Fifth, it can reach 100,000:1 ultra-high contrast ratio, and the clarity is higher. The above performance advantages determine that the LED backlight is technically a substitute for the cold cathode backlight, and the current market is basically 150% of the cold cathode backlight products.

There is no choice for the LED backlight itself,The main choice of the whole machine is the choice of the technical performance parameters of the LCD panel,For example, maximum physical resolution、Dynamic response time, etc.,It is the same as an ordinary LCD TV。

The difference between the two is that it is backlit, the LCD uses a cold cathode fluorescent tube, the LED uses a light-emitting diode, the LED is more power-saving than the LCD, the effect is almost the same, but the LED is thinner and smaller than the LCD.

The backlight is different.

Buy an LED backlight.

Difference:Don't say it,When the weather is cold,When the room temperature is very low(That is, winter),CCFLThe brightness of the TV with backlight is generally not high,It also feels that the TV is very dark,The effect is not good if it doesn't light up。 This problem is not present with LED backlighting.

Others, not to mention, LED cost is low, ** is also cheap, now a little better are LED, the eliminated products don't buy.

To put it simply, LCE (at least 60-80 inches) is the choice of LCE (at least 60-80 inches) for the large screen, and LED (below 60 inches) is selected for the small screen
