Question 1: What is plasma TV, and what does plasma mean? It uses small pixels filled with inert gas. After energization, the gas attacks the phosphor luminous body. After the energization is completed, it will emit light. This is completed in a very short time. It takes 8 discharges per second. The full name of plasma TV is Pla***a Display Panel, which is called plasma TV in Chinese. It is a device that injects mixed gas between two ultra-thin glass plates and applies voltage to use phosphors to emit images. Compared with CRT picture tube monitors, it has the characteristics of high resolution, large screen, ultra-thin, rich and bright colors. Compared with LCD, it has the characteristics of high brightness, high contrast, large viewing angle, bright colors and rich interfaces. Characteristics of plasma TVs: (1) Thin and light structure. The PDP display module is thin and light, which determines the overall structural characteristics of the display screen. At the same time, the increase in display size does not require a corresponding increase. The thickness of the large screen body. (2) Wide viewing angle: PDP can achieve the same wide viewing angle as CRT, more than 160 degrees up, down, left, and right. The viewing angle of liquid crystal (LCD) is generally about 120 degrees in the horizontal direction, and even less in the vertical direction. (3) Anti-electromagnetic interference Due to differences in display principles, electromagnetic interference from the outside, such as motors, speakers, etc., has almost no impact on the image of the PDP. In contrast, CRT is much more affected by electromagnetic fields. (4) Flat images have no distortion. The RGB grid of PDP is evenly distributed on the plane, while in flat CRT, the inner surface is not flat, which will cause typical pincushion distortion. And when the local brightness of the picture is uneven, CRT often produces corresponding image distortion, while PDP does not have this phenomenon. (5) There are no convergence and focusing problems. Plasma TVs are high-tech and cutting-edge electronic products that are relatively unfamiliar to many customers. Many people are cautious when using them because they do not understand its principles, so they cannot fully enjoy the plasma. The enjoyment brought by TV The inherent defects of plasma TV: (1) The service life of the display panel is short. I hope these answers can
Question 2: What is the plasma in plasma TV? What does it mean? The plasma state refers to the attraction of electrons in the atoms of a substance breaking away from the nucleus at high temperatures, causing the substance to exist in a state of positive and negative charged particles.
In our daily life, we encounter various substances. According to their state, they can be divided into three major categories, namely solid, liquid and gas. For example, steel is a solid, water is a liquid, and oxygen is a gas. Any substance can transform between these three states under certain conditions. Taking water as an example, under a standard atmospheric pressure, when the temperature drops below 0°C, water begins to turn into ice. When the temperature rises to 100°C, water will boil and turn into water vapor.
How will the gas change if the temperature continues to rise? Scientists tell us that at this time, the atoms that make up the molecule split and form independent atoms. For example, a nitrogen molecule will split into two nitrogen atoms. We call this process the dissociation of gas molecules. If the temperature is further raised, the electrons in the atom will be stripped from the atom and become a positively charged nucleus and negatively charged electrons. This process is called ionization of the atom. When this ionization process occurs frequently and the concentration of electrons and ions reaches a certain value, the state of the material changes fundamentally, and its properties become completely different from those of gases. In order to distinguish it from the three states of solid, liquid and gas, we call this state of matter the fourth state of matter, also called the plasma state.
In the vast and boundless space of the universe, the plasma state is a ubiquitous state. Most of the luminous planets in the universe have high internal temperatures and pressures, and the material inside these planets is almost always in a plasma state. Solid, liquid, and gaseous materials can only be found in dim planets and scattered interstellar matter.
Plasma matter is often seen around us. Traces of it can be found in fluorescent lamps and neon lamps, and in the dazzling incandescent arcs.
In addition, wonderful plasma states can also be found in the ionosphere around the Earth, in beautiful aurorae, flash discharges in the atmosphere and the tails of meteors.
Plasma is a new generation display device using plasma flat screen technology that has developed rapidly in recent years. There are two types of products currently on the market, one is a plasma display screen, and the other is a plasma screen. There is not much difference between the two in nature, the only difference is whether there is a built-in TV reception tuner.
Since the initial development of PDP was mainly for commercial display purposes, there are still many PDPs that do not have built-in TV reception tuners, that is to say, they cannot directly receive TV signals. Therefore, if you choose this product, you can only use other equipment such as a satellite decoder or video recorder to double as a TV signal tuning receiver, or you can purchase an additional TV receiver. Nowadays, plasmas have begun to be designed and produced for home users. Some of the plasmas currently produced have built-in TV receivers. These models are pre-equipped with RF radio frequency connection terminals and can directly play TV programs.
Most domestic PDPs have built-in TV receivers, such as many products from Hisense, SVA and TCL. As for foreign manufacturers, some products use external TV receivers, and some products use built-in TV receivers. PDPs with external TV receivers are generally called plasma displays, and PDPs with built-in TV receivers are called plasma TVs. When purchasing, you should ask whether it has a TV reception function.

Question 4: What does plasma mean? Plasma is when the ionization process occurs frequently and the concentration of electrons and ions reaches a certain value, the state of the material changes fundamentally, and its properties become completely different from those of gas. In order to distinguish it from the three states of solid, liquid and gas, we call this state of matter the fourth state of matter, also called the plasma state.
Question 5: What is a plasma TV? The imaging principles of plasma TVs and LCDs are completely different. LCDs illuminate the screen through a large backlight, while plasmas illuminate each screen. The pixels are all glowing. Some people say that the plasma screen is covered with plasma electric guns, and each pixel is a gun that can be lit up. But in fact, each pixel in the plasma screen is composed of three glass air chambers, and so on through a large number of glass air chamber groups to form a flat panel.
Each glass gas chamber contains inert gas. A pixel is composed of three gas chambers, and then the three gas chambers of this pixel are coated with red phosphor, green phosphor and blue respectively. Phosphor. Then each gas chamber is discharged through the electrode wires under the control of the drive circuit. The discharge in the inert gas in the gas chamber causes the ion to emit ultraviolet light, which then excites the phosphor to emit light. This achieves plasma imaging.
The brightness of the plasma is related to the discharge frequency of the wire. Through the control of the drive circuit, the faster the discharge frequency, the greater the brightness. This is the complete imaging method of plasma TV. Because imaging is achieved through high-temperature discharge, each gas chamber pixel must have a certain distance. This is why the resolution of plasma TV cannot be very high. CRT TVs are recognized as the most colorful TVs currently. If colors and species are assigned to LCD TVs and plasma TVs, then LCD is the color and plasma is the species.
Question 6: What does plasma mean? Can anyone give an analogy? Plasma state refers to the attraction of electrons in the atoms of matter breaking away from the nucleus at high temperatures, causing the matter to exist in the state of positively and negatively charged particles.
Question 7: What is a plasma tube? A plasma tube refers to a slender glass tube with a diameter of about 1mm, which is applied by filling a mixed gas penalty between two thin glass plates. The voltage causes it to generate ion gas, and then the plasma gas discharges and reacts with the phosphor in the substrate to produce a color image. This plasma tube is made into three colors of RGB, and then by arranging the three-color plasma tubes, it can be realized Ultra-large, high-definition display.
