Where is the gap between LCD TVs and plasma TVs?

Plasma TVs that were popular a decade ago, nowadays, plasma TVs have been completely replaced by LCD TVs. However, there are still insiders saying that “outsiders buy LCDs and insiders buy plasmas.” How big is the difference between the two, and where are their characteristics? What is the difference between the two? Today we will talk about this issue~

First of all, take a look at the advantages and disadvantages of LCD TVs and plasma TVs:
LCD TVs can compete with plasma TVs with only 42-inch LCD TVs. Taking the 45-inch LCD TV launched by Sharp in 2006 as an example, the market price is nearly 70,000 yuan, while the price of the plasma TV with the same display area has dropped to less than 20,000 yuan. It will take a short period of time for LCD TV prices to fall within the similar price bands of plasma TVs of the same specifications. The reason for this is mainly due to the lower yield rate in the manufacturing process of the large-screen liquid crystal display panel, resulting in the inability to reduce the cost. The technology of large-screen liquid crystal display panels is still relatively closed, and there is still no competition for mass production in the world, and there are also great differences in quality.

What is a plasma TV?

The full name of plasma TV is Plasma Display Panel. Chinese is called plasma TV. It is a device that injects a mixture of gases between two ultra-thin glass plates and applies a voltage to generate light using phosphors. Compared with CRT tube display, it has the characteristics of high resolution, large screen, ultra-thin, rich colors and vivid colors. Compared with LCD, it has features such as high brightness, high contrast, large viewing angle, bright colors, and rich interfaces.

What is an LCD TV?
Liquid crystal display, referred to as LCD (Liquid Crystal Display). LCD, full name "Liquid Crystal Display", translated as liquid crystal display, referred to as "liquid crystal display."

Now, let's compare the following points: Is LCD TV better or plasma TV better?
1, performance indicators

The nominal brightness and contrast index of plasma TVs are higher than those of LCD TVs. The contrast ratios of plasma TVs are basically 3000:1, 4000:1, and 5000:1. The latest ones have reached 10,000:1, and the brightness is mostly 500cdm2~1000cdm2. ; LCD TV contrast index is basically between 400:1-1200, most of the brightness in the 400-800cmm2, only from the nominal indicators, plasma TV is higher than the LCD TV, I believe this is the performance of plasma TV is better than LCD TV The origin of the argument.

2, the service life plasma TV and LCD TVs are mostly the initial standard of 25,000 to 30,000 hours, while the new generation of plasma screens have reached 60,000 hours of life, with the development of technology, plasma TV life may be further improve. LCD TVs are also exploring new light source technologies such as LEDs to extend their life.

3. From the perspective of watching high-definition movies from technology, LCD TVs make people feel very thin when watching movies and television. The contrast is too high and there is no level and thickness of plasma TV. This is better understood: watching high-definition movies on LCD screens, each frame of the picture is very detailed and refined, but coherent, moving like watching continuous playing PPT or all movies have a sense of color silhouette and animation , It feels very fake and floating, no hierarchy, no sense of reality. The pixel sense of the plasma TV image is stronger, especially the product with a resolution of 852×480, and the LCD TV image is more delicate; in terms of color, the color of the LCD TV is generally saturated and somewhat warm. The color of plasma TVs is more natural and fresh.

4. The power consumption rate of plasma TVs is higher than that of LCD TVs. At present, the nominal power consumption of most plasma TVs in the market is in the range of 300W to 400W, while LCD TVs rarely exceed 200W.
5, due to different perspectives of the perspective of the principle of light, plasma and LCD TVs can reach 170 degrees, but the LCD TV viewing angle in the large angle, the screen will have color cast phenomenon, and plasma is no such problem. Therefore, plasma TV is more suitable when the whole family is watching together or when the living room area is large.

The above five points are a contrast between LCD TVs and plasma TVs. In fact, there is no such thing as who is better. Everything is determined by the market. Now that plasma production is suspended and LCD is prevalent, there must be reasons for it.

Y-strainer is the transmission medium pipeline system indispensable to a filter device, Y-strainer is usually installed in the relief valve, relief valve, water level valve or other equipment imported to remove impurities in the media , To protect the normal use of valves and equipment. Y-strainer with advanced structure, resistance, easy to drain and so on. Y-strainer for medium can be water, oil and gas. General water network is 18 to 30 mesh, ventilation mesh for 10 to 100 mesh, oil network for the 100 ~ 480 mesh. Basket filter mainly by the takeover, charge, filter blue, flange, flange cover and fasteners and other components. As the liquid passes through the main tube into the filter blue, the solid impurity particles are blocked in the filter blue, and the clean fluid through the blue filter, the filter outlet.
