What is the difference between plasma and liquid crystal?Is it better to have a hard or soft LCD scr

LCD and plasma have their own advantages and disadvantages,Generally like ** sports programs or action blockbusters,Suitable for buying plasma TV,Plasma TV picture is soft and not dazzling,Good display dynamic picture effect,There will be no tailing phenomenon,Suitable for use in the living room or large room,But its heat generation is larger,Electromagnetic interference is also larger,The life of the plasma screen is generally about 40,000 hours,The life of the traditional CRT picture tube is about 20,000 hours。 The LCD TV shows the best effect of the still picture,But the display dynamic picture is not as good as the plasma,There are also problems such as dead pixels and light leakage,But its weight is lighter,The heat generation is small,Electromagnetic interference is also very small,The life of the LCD screen can reach about 60,000 hours,Suitable for use in the bedroom or small room,The general popular type mostly uses a hard screen,And high-end models mostly use a soft screen。 LCD TVs display the highest definition of still images, but the clarity of dynamic picture plasma is higher.

Plasma and LCD both belong to flat-screen TVs, and now they are all installed with digital TV format to produce 16:9 picture specifications, while traditional TV programs are 4:3 picture format, so flat-screen TV**4:

3 will appear widening and deformation, but I believe that in the near future, with the popularization of digital television, 16:9 TV programs will be popular. It's a good soft screen is a good hard screen,That picture is clearer--- this is the same,Starting from the place of origin,Hard screen (i.e. IPS screen),It is an LCD TV screen jointly produced by Philips and LG,The soft screen is divided into Japanese (Sharp)、Korean (Samsung)、Taiwan (Chimei、 AUO), soft and hard refers to the degree of water ripple, in fact, there is not much difference in the screen itself, mainly in the production process, from contrast, resolution, service life There is not much difference, but as long as it is a hard screen, it is an IPS screen for the time being, which also simplifies the purchase of the screen for the landlord. Oh.

Nowadays, most of the TVs on the market are plasma TVs and LCD TVs,Many people will be very entangled when choosing,I don't know which one to choose,So what is the difference between plasma and LCD?See below.

1. Resolution: Although the plasma screen is large, the resolution is not as high as that of LCDThe LCD screen is small, but the pixels can be made smaller, so the resolution of the liquid crystal is higher.

2. Brightness: Now the LCD panels on the market have generally adopted the technology of multiple lamps, and the brightness has also been greatly improved, so under the premise of the same parameters, the brightness of LCD TV is better than that of plasma TV.

3. Power consumption: Even if the plasma TV uses the method of interlaced luminous display, it reduces the power consumption, but compared with the LCD TV with the same parameters, the power consumption is still greater than that of the LCD TV.

5. Service life: The life of plasma is generally 10,000 hours, while the life of LCD TV is generally higher than 60,000 hours.

The above is that I have introduced to you the difference between plasma and liquid crystal, I believe you have a certain understanding of this, I hope it can help you.

It is difficult to distinguish between LCD TV and plasma TV, but according to similar products in the TV market, LCD TV is the dominant market. LCD TV has a more mature market and product production process in China. And plasma TV,The market share of TV is not high,**It is not acceptable to the public。

And the difference between plasma TV and LCD TV is very insignificant, there are many manufacturers, there is no obvious visual difference between LCD and plasma. However, it is only a simple introduction to the product, and it is difficult for consumers to distinguish the difference between liquid crystal and plasma.

Under the current technical conditions, plasma is still good! There is no limitation of resolution, the color reproduction is real, the brightness is moderate, the damage to the eyes is small, the picture is soft, and the lead-free process is used in screen manufacturing!

LCD TV has a resolution limit (LCD monitor has only one optimal resolution), the number of colors is small, the color is relatively fake, the dynamic picture is not sharp, there is trailing (the larger the screen, the more serious the tailing), the dynamic contrast is high, the eye damage is great (it is easy to cause eye fatigue for a long time), the picture is not well layered, and the black display is not perfect! And due to the current technical limitations, it is inevitable to use harmful substances such as lead in the production process!!

Same resolution, good plasma, no tailing, good color, good contrast. However, the power consumption is high, generally around 70% of the nominal value. The screen is hotter,** higher than the LCD.

Originally, LCD has two major shortcomings that can't catch up with plasma TV,First, the angle is small,You can't even see the color reversal of the image when you look at it from the side。 The second is the slow response (generally 160ms-200ms), which makes the moving scene unclear and the image has tailing. But through technical improvements, both of these issues were satisfactorily resolved in 2005:

The new technology makes the first angle reach 178 degrees, and the response time is shortened to 4 milliseconds, so that the liquid crystal has the advantage of rolling over the plasma (plasma disadvantages: large power consumption, short life, can not be made into small size, station standard burn-in), now, plasma has disappeared, liquid crystal is the world.

Compared with the color plasma screen and the color picture tube, the color LCD screen has many advantages, mainly: energy saving, power consumption is very saving, it is one-half of the plasma screen, one-fifth of the picture tube. Long life:

30 years; The screen is large and small, a quarter of the thickness of a plasma screen and almost one percent of the thickness of a picture tube. No radiation, no damage to the body of the ** person. Compared with CRT, there is also the advantage that the image is not distorted or distorted.

Before 2006, the color LCD screen had two fatal shortcomings that made it unable to comprehensively surpass the plasma screen and picture tube: one is the small angle, only 30 ° 40 °, outside this angle, the color is distorted or even reversed. The second is the slow response, between 150ms and 200ms, and the tail is serious when playing sports programs and games, which makes the person very uncomfortable.

But in 2006, the TFT screen was invented, and the two shortcomings were overcome, and the angle could reach 178 °, that is, as long as it was in front of the screen, the effect of any angle was the same. The response time is increased to 4ms, and no matter how fast the movement is, there will be no tail (the limit of the human eye is 62ms, or one-sixteenth of a second).

TFT screen, also called true color screen, is to add a thin film transistor (actually an insulated gate FET) on each pixel corner to drive the LCD, this trick is really powerful, all of a sudden the color picture tube and color plasma screen out of the historical stage, almost become the color LCD screen domination of the world. Although there are OLED screens that want to compete with them, OLED screens have a fast aging and short lifespan, and they are still not comparable to LCD screens.
