What is the difference between a plasma TV and an LED TV?

There is no real LED TV on the market now,Only LED backlight LCD TV, it has the advantages of energy saving, high brightness, thinner shape than traditional CCFL backlight LCD TV, but it is much more expensive。 In fact, the LED backlight really wants to achieve uniform brightness to use the direct type, and the most expensive way on the market is basically not, and the thickness is difficult to reduce, now the market is basically low-cost side-mounted LED backlight, in addition to energy saving, thin thickness is theoretically longer service life.

The advantage of LCD TV is energy saving,No flicker at all is conducive to protecting eyesight, but the dynamic response is poor, there is dragging,Now the double-speed circuit can reduce the shadow to a certain extent,If you have flowers in the growing stage,Or buy an LCD TV with 100Hz or 200Hz double speed;

The advantages of plasma TVs are that the dynamic response is fast, the color is good, but when the same image is displayed in the same position for a long time, there will be a permanent slight residual image, and the phenomenon of screen burning has now been greatly reduced. If you are a sports fan, buy a plasma TV,But it should be noted that the parameters marked500Hzor600HzThe frequency is not the screen refresh rate mentioned by the display,It should be subject to the actual effect,So as not to hurt your eyes with long-term use。

Compared with the TFT-LCD liquid crystal with the backlight of ordinary cold cathode fluorescent lamps, the LED backlight has some advantages.

1. The uniformity of the backlight is better, and there will be no uneven black.

2。The contrast ratio is better, and the LED can turn off the backlight under a completely black screen, so as to achieve a better dynamic contrast.

3。The color performance is better, because the tri-color LED backlight can be used, the color temperature can be effectively controlled, so as to get more realistic colors and a wider color gamut.

4。Since the LED is driven by a low voltage, the boost circuit of the cold cathode backlight is omitted, and it can be made thinner.

5。If you use dynamic LED backlight, (the principle is to use 2 image drives, one drives the LCD screen, and the other drives the LED in the way of an outdoor large-screen LED display wall, and the resolution of the drive does not need to be too high), then the 47-inch LED backlight LCD TV can achieve dynamic power consumption, the minimum power consumption can be 10 watts, and the maximum brightness is below 200 watts, and the contrast ratio can exceed 100000:1, the brightness can reach 1000 nits, and the color gamut is 132%ntsc, In turn, PDP is left far behind (except that it is slightly less responsive).

If you only need to watch discs, of course, it is plasma, if you watch TV and discs, it is still good for LCD, low power, and durable. Burners say that the saturation, smearing and black of plasma are much better than liquid crystals, but in fact, when you go to Gome to see for yourself, there is not such a big difference. Unless your eyes are particularly poisonous.

The essential difference is in the backlight.

LED TV is good.

LED TV is actually LCD TV (liquid crystal display), that is, a kind of LCD TV, it is different from the traditional LCD TV mainly in that it uses different backlights, which brings many differences in performance.

LED TV uses light-emitting diode as the backlight, which has more advantages than the traditional LCD TV with CCFL backlight in terms of thickness, picture quality, life, energy saving and environmental protection, and has become the recognized development direction of LCD TV in the industry.

Difference Between LED TV and LCD TV::

1. LED TV is actually a kind of LCD TV, but it is different from the backlight of traditional LCD TV. The backlight of LED TVs is LED, while ordinary LCD TVs use cold cathode fluorescent tubes as backlights.

2、The appearance of LED TV is thinner,The thickness of traditional LCD TV is generally about ten centimeters,And LED TV is thinner,The thinnest is even only two centimeters,More fashionable and trendy。 The clarity of LED TV is also higher than that of traditional LCD TVs, and the color gamut is also wider, which makes the picture quality more excellent.

3. The cold cathode fluorescent lamp used in the traditional LCD TV contains mercury that is harmful to the human body, while the backlight of the LED TV does not contain mercury, which is green and environmentally friendly, healthy and fashionable, and is also very energy-saving and power-saving, and its energy consumption is about 50% lower than that of the cold cathode backlight, and the life is longer.

The imaging principle of LCD TV and plasma TV is different. LCD TV is passively emitted, relying on the luminous tube behind the LCD screen to illuminate the LCD screen in front of it, and the screen itself will not light up. Plasma TV, on the other hand, is actively emitted, and the screen will light up by itself.

LED is to replace the light-emitting tube behind the LCD screen with LED light-emitting diode, because the LED light-emitting component is very thin, which reduces the thickness of the TV, so we see that the LED TV on the market is less than a finger thick.

Because plasma TV is actively emitting light,So it does not have the response time of LCD TV,That is, the picture does not fall off,The moving picture is smoother。 The disadvantage is that the picture is a bit flickering and not as stable as LCD.

Which one to choose,You make your own idea,I recommend plasma TV,The picture is softer,Good for the eyes,Because it is active light, it is more power-saving。

LED!, of course

LCD is an LCD TV with a backlight of a CCFL cold cathode tube, and the most common TV in the market is about to be eliminated.

Plasma TVs are devices that inject a mixture of gas between two ultra-thin glass panels and apply voltage to use phosphor to emit luminescence images, and consumer acceptance and market sales are average.

LED is an LCD TV with an LED backlight. LED light source replaces the traditional fluorescent tube, the picture is higher, the theoretical life is longer, the production process is more environmentally friendly, and the liquid crystal display panel is thinner, compared with LCD and plasma, the appearance is more beautiful, the weight is lighter, the lamp life is longer, and now the mainstream products in the market!

As for what brand to buy, I will also give you advice:

If you consider buying a domestic brand, Hisense, Konka, Skyworth quality is good, and the after-sales service of domestic brands is better than that of joint ventures!

If you decide to buy a joint venture brand, it is recommended to buy Sharp (the originator of LCD TVs) or Sony (recognized as the clearest picture quality)!

LCD, cheap, low threshold, can do, LED, the upgraded version of LCD, optimized display and shape, low standard consumption. Advantages: high brightness, good chromaticity, high sharpness, light and thin, relatively power-saving.

Plasma, cost-effective, good color reproduction, soft color, high contrast, high dynamic definition, each has its own advantages, and none has an overwhelming advantage.

LCD, domestic selection Hisense, joint venture Sony. Samsung.

Plasma, Panasonic.

Now there is no LED screen.

Plasma is suitable for placing in the hall, and the effect is better. It's like a ball game, and it looks enjoyable.

The liquid crystal is placed in the bedroom, and it is better to see the static effect.

LCD TV vs. LED TV:

The imaging is all LCD screen imaging. It's just that the backlight is different. One is that the lamp emits cold light for illumination. One is illuminated with LED tubes.

Plasma TV: Pixels (the elements imaged) are formed by plasma field luminescence. No additional lighting is required.

The liquid crystal effect is good, just look at the computer screen to know As for the drag, now there are 2ms of it, and it will definitely not drag and then the best liquid crystal is Sharp, and Sharp is known as the father of liquid crystal.

LCD, play games. Listen to me, and you can ask me questions.

LEDs are good.

Plasma has many defects.
