LCD TV vs. plasma, the difference between plasma TV and LCD TV

Large screens (42 inches or more) generally choose plasma, and small and medium-sized screens are very cost-effective because of the plasma screen, so there are few products, only LCD

The advantages of LCD are sharp imaging, high brightness, no radiation (low radiation), and low energy consumption.

The disadvantage of LCD is that the black color is not pure, and the dynamic response is not good (there has been a great improvement, but it is still slightly inferior to plasma, which determines the viewing effect of action movies and ball games).

The advantages of plasma are good color reproduction (strong ability to sink black), soft picture, good dynamic response, the disadvantages of plasma are slightly poor brightness, high energy consumption, radiation, and long-term ** The same fixed picture will produce the phenomenon of "screen burning".

In terms of the comprehensive indicators of the two, plasma has a slight advantage, and LCDs with the same technical indicators as plasma of the same size are not cheaper than plasma.

To sum up, at home, if you mainly watch TV and movies, plasma is preferred above 42 inches, and below 42 inches, there is basically no choice, then there is only LCD.

<>First of all,The biggest difference between the two is the different panels usedPlasma TVs rely on high voltages to activate special gases in the picture unitAnd thenIt produces ultraviolet light to excite phosphorescent substances to emit light. LCDA TV uses an electric current to change the structure of the crystal inside a thin-film transistor on an LCD panel to make it visibleofSecondly, plasma TVs are generally cheaper than LCD TVs, but LCD TVs have advantages over plasma TVs in terms of power-saving performance and display resolution. The contrast ratio of plasma is mostly 3000 at this stage

Plasma TV is a display technology that uses gas discharge and works much like fluorescent lamps. It uses a plasma tube as a light-emitting element, each plasma tube on the screen corresponds to a pixel, the screen uses glass as the substrate, the substrate is spaced at a certain distance, and the surrounding area is sealed by air tightness to form a discharge space. The discharge space is filled with mixed inert gases such as neon and xenon as the working medium.

The inner surface of the two glass substrates is coated with a metal oxide conductive film as an excitation electrode. When a voltage is added to the electrode, the mixed gas in the discharge space is discharged plasma. The gas plasma discharge produces ultraviolet light, which excites the phosphor screen, which emits visible light and displays an image.

Liquid crystal is a substance between solid and liquid states, and it is an organic compound with a regular arrangement of molecules, and if it is heated, it will appear in a transparent liquid state, and when it is cooled, it will appear in a cloudy solid state of crystalline particles. It is precisely because of this property that it is called liquid crystal. The molecular structure of the liquid crystal used for liquid crystal displays is similar to that of a thin matchstick, and it is called Nematic liquid crystal, and liquid crystal displays made of this type of liquid crystal are also called LCDs.

The LCD TV is in the liquid crystal between two glasses, add voltage, through the molecular arrangement changes and zigzag changes to reproduce the picture, the screen through the collision of electrons, create a picture, and form a picture through the perspective reflection of external light.

The comparison of the two screens is mainly due to the different fillers in the middle of the two glass substrates, one is inert gas, and the other is liquid crystal particles. Of course, there is also a big difference between the display effect and the screen volume, the LCD volume is small, and the display effect is also good.

LCD TV has the characteristics of no flicker, light and thin appearance, low radiation, high resolution, higher brightness, etc., and LCD screen has been widely used in the PC field, but LCD technology lags behind plasma in terms of large screen, and the cost of large-screen color TV is high, and it is easy to be affected by the viewing angle.

Plasma TVs have richer colors, large viewing angles, and short response times. The contrast is higher, the image has a stronger sense of hierarchy, the color reproduction characteristics are good, and the display image color is bright and saturated. Moreover, it is relatively easy to make the screen larger, but its disadvantages are large power consumption, limited life, and easy aging.

Plasma TV has high dynamic definition, no residual image tailing, obvious advantages in image quality, and high comfort for a long time, suitable for friends who like to watch action blockbusters or sports programs; LCD TV product line is rich,The appearance is more fashionable,The picture clarity is higher,And the radiation is relatively small,There are more additional functions of TV,For example, Internet function、Changhong's music education function can better meet the needs of the family。

There are two kinds of liquid crystals, LED and LCD, LED color, brightness, frequency response, and life are all higher than LCD. In the future, liquid crystal is the world of LED. The LED screen is a light-emitting diode principle, with three primary color light-emitting tubes forming a light-emitting point.

LCD is more difficult to understand. Upstairs said. Plasma is the principle of gas discharge, and it is also a luminous point composed of three primary colors of luminescence.

It is not easy for LED to be big, and it is not easy for plasma to be small, which determines that the plasma screen is not small, the LCD screen is not large, and the high resolution of the liquid crystal cannot be done by plasma. In terms of color, plasma is dominant, but now LED technology is mature and comparable to plasma. Plasma dominates the shadow aspect, the power consumption liquid crystal will be low, the volume of liquid crystal will be small, the health aspect of LED is an absolute advantage, plasma radiation also exists, liquid crystal development to a certain extent will replace plasma technology, now all kinds of micro electronic products, basically liquid crystal, plasma can not get, power consumption and volume is difficult to built-in.

Plasma is basically made by devils, and the whole world is working on liquid crystals. The common denominator of the two is that there will be individual or local bad pixels, so you should be able to choose when buying, and it is always difficult to feel comfortable when you buy a bad one.
