Working principle of plasma TV)

The principle of plasma TV is composed of countless plasma display units. The structure of plasma display units is similar to that of fluorescent lamps. The difference is that the electrodes Replace the filament to create an electric field, and inert gases replace mercury, the upper and lower two-layer glass substrate replaces the tube wall of the fluorescent lamp.

Plasma display units on plasma screens

The plasma display unit consists of two front and rear glass substrates. The front panel glass has transparent ITO electrodes and bus electrodes that enhance Ito conductivity, and covers transparent dielectric layer and magnesium oxide protective layer on the electrodes, it mainly protects the electrode from the loss caused by discharge impact. There are data electrodes, dielectric layers and strips on the rear panel glass, and red, green, and blue fluorescent materials are printed in each compartment. After vacuating between upper and lower substrates, a thin mixed gas is encapsulated.

When the electrode is powered on, the electrons between the two electrodes escape to form a current, forming an electric field to stimulate the inert gas into a plasma state, the plasma state of the inert gas and the electronic collision to produce ultraviolet rays, red, green, and blue fluorescent powders are stimulated by ultraviolet rays to produce the corresponding colors.

Working principle of PDP TV

Here we can see that the plasma TV and the LCD TV are different in the way of light, the plasma TV uses the active light, each of its small pixels is shining, although each Plasma Display Unit consumes a low power consumption, the consumption of so many plasma display units together is also very large. When the inert gas is activated as a plasma, it needs to absorb energy. In addition, when the inert gas is stimulated by an electronic collision to produce ultraviolet rays, heat is inevitable, the heat is not used in the display process, and is lost in vain, which also increases the power of plasma TV.

the same as an LCD TV, the plasma TV power increases as the screen increases, only the plasma display unit is added instead of the cold cathode fluorescent tube. Plasma TV consumes a lot of power and is known as a high-energy TV. In summer, even like an oven, it has been prevalent. However, with the continuous development and improvement of plasma technology in recent years, it has greatly improved.
