Is the credibility of LED LCD TVs high?

You don't have to doubt it. LED has been very mature, and its advanced nature compared to traditional CCFL LCD TV has become a foregone conclusion. More and more people will buy it.

LED is an advanced liquid crystal solution that replaces the traditional liquid crystal backlight module with LED.

Advantages of LED backlight technology:

High brightness, and stable brightness and color performance over the lifetime.

A wider color gamut (more than NTSC and EBU) for more vibrant colors.

The backlit white balance can be adjusted while maintaining the overall contrast. When the user's ** source is switched between the computer and the *** machine, the white balance can be easily adjusted between 9600k and 6500k without sacrificing brightness and contrast.

Real-time color management. Since the three colors of red, green, and blue emit light independently, it is easy to precisely control the current display color characteristics.

It can provide continuous area array light sources for large screens.

Reduce the artificial traces of dynamic scenes without sacrificing brightness and longevity. Because the flickering frequency of traditional CCFL lamps is low, the expression of dynamic scenes may produce a jump. The LED backlight can flexibly adjust the light emission frequency, and the frequency is much higher than that of the CCFL, so it can perfectly present the moving picture.

Wide range of brightness adjustments. It's easy to implement LED power control, unlike CCFL, where there is a threshold for minimum brightness. Therefore, whether it is in bright outdoor or completely dark indoors, it is easy for users to adjust the brightness of the display device to the most pleasing state.

Wide operating temperature range, low voltage, shock resistance. Because of the use of solid-state light-emitting devices, the LED backlight has no squeamish parts, and it is very adaptable to the environment.

Low electromagnetic radiation. The LED light source does not produce any rays, nor does it have toxic substances such as mercury, so it can be described as a green light source.

To sum up two points,LED LCD TV has the advantages of power saving、Environmental protection、More real color,It will definitely become the development direction of LCD TV。

Personally, I feel that I still trust the IPS hard screen, at least it is a high-end product.

And now so many people are saying yes, there will be no mistake. It is said that the LED backlight LCD TV of the IPS hard screen is very good. Hehe, I'm thinking about when I can get one!

The LED backlight TV is much thinner than the LCD one, and the appearance is slightly better, and there is no big difference between the real ** TV shows.

The effect of LED TV or hard screen will be very good...

And the quality and reputation are good.

Whether the credibility is high or not, it is necessary to slowly replace the LCD TV with CCFL backlight.

The IPS LCD screen is used to respond faster, the picture is more coherent and smooth, and the performance is more perfect.

The quality of LCD TV mainly depends on three aspects: one is the LCD panel, and the other is the quality and order of the backlight tube.

Clause. First, you can let the shopping guide play out the LCD menu,**The brightness value in the menu,Because the LCD TV will be darkened after a long time,This will definitely affect the future **effect,And now there are many low-priced LCD manufacturers on the market,The brightness value is at least 70,The brightness of a good LCD panel is generally about 30,Remind consumers to open the menu to see the brightness value when buying LCD。

Clause. Second, to see if the LCD screen has white dead pixels, you can generally observe on the screen with relatively high brightness, once you see the dead pixels, it proves that this LCD screen must be an inferior screen. After reading the quality of the screen, it is recommended that consumers ask the shopping guide,Which manufacturer is used in the backlight tube,Generally, the backlight tubes used in the market are imported Philips backlight tubes,You can't ignore the order of the backlight tubes。 Because the market generally adopts a cylindrical arrangement, but the brightness of this arrangement is uneven, and the utilization rate of light energy is not high; Many foreign brands are arranged in U-shaped tubes, so that the brightness is uniform and the life is longer.

1. High resolution.

2. The hard screen is better than the soft screen.

Now the LED TV,In fact, the LED light-emitting diode is used as the backlight of the LCD screen,It has five advantages over the cold cathode fluorescent tube backlight:First, the ultra-wide color gamut,It can reach 105%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, higher clarity. 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。

There is no difference between the core and essential parts, they are all liquid crystals.

The LCD panel itself does not have brightness, and needs to use the light source behind it. In the past, fluorescent tubes were installed behind LCD panels, but they were not ideal in terms of lifespan, heat generation, light balance, and thickness. The current so-called LED is to replace the fluorescent tube with an LED light-emitting device (which can be understood as a thin, low-consumption, brightness balanced fluorescent lamp) to improve the above defects.
