In recent years, the majority of consumers who buy TVs have started to love flat-panel TVs. At present, there are mainly two kinds of flat-panel TVs on the consumer electronics market, namely plasma TVs (PDPs) and LCD TVs (LCDs). Look, it is difficult to distinguish between these two kinds of televisions, but in essence, there is a big difference between the two, but where is the difference between plasma TVs and LCD TVs?
Although it is difficult to distinguish between plasma TVs and LCD TVs from the outside, it is even difficult for ordinary consumers to distinguish between LCD TVs and plasma TVs. However, they are almost completely different. The technology and working principle, which also led to the essential difference between plasma TV and LCD TV.
1. The biggest difference between plasma TVs and LCD TVs lies in the fact that they use different panels, which means that their imaging principles are quite different. A plasma television relies on a high voltage to activate a special gas in a developing unit, so that it generates ultraviolet light to excite a phosphorescent substance; and an LCD liquid crystal television uses a current to change the structure of a crystal in a thin film transistor on a liquid crystal panel, making it Imaging.
2. Plasma TVs are better than LCD TVs in processing moving images, but when static images appear on the plasma screen at the same position for a long time, burns may occur. When a plasma TV suffers from burns, when the camera is turned on and off, the long-playing image appears on the screen as if it were printed on the screen.
3. Plasma TVs and LCD TVs use different methods of contrast measurement. Even the measurement methods adopted by each company are different. Plasma TVs are mostly measured in black and white, and the contrast is generally high. Some contrast ratios are as high as 8000:1. If measured in accordance with the American National Standard ANSI, the contrast between plasma TVs and LCD TVs is mostly around 200:1 or 300:1. This measurement method is to compare the black and white of the same image display.
4, LCD TVs in the definition of higher ion TV, almost all LCD TVs can reach 1024 × 768 high resolution, the highest has reached 1920 × 1080. The physical resolution of plasma TVs sold in the market is mostly 852×480, and only a few plasma TVs have a physical resolution of 1024×768.
5, the smaller particles on the LCD screen, finer lines, the image display is more smooth; while the plasma has a distinct sense of the line, the picture appears rough. In terms of dynamic performance, plasma has an inherent advantage. When playing a dynamic movie, the plasma is quite smooth, while the liquid crystal has a slight "smear" phenomenon. In terms of color performance, plasma and liquid crystal have their own advantages, plasma color is slightly brighter, the picture looks brighter, and LCD is better than the color transition, natural and soft.
6, the current plasma and liquid crystal can reach 170 degrees or more, but from the overall analysis, plasma TV is better than the LCD TV in perspective, but for living room, bedroom TV, few people will go in more than 120 degrees watch TV.
7. The response time of LCD TVs is mostly around 12 milliseconds, which is slower than that of plasma TVs. For a fast moving black image or white image, the LCD TV has a slight tailing phenomenon, but this does not mean that for a fast moving white object, the plasma TV will also have a slight tailing phenomenon, only when it is fast moving. When the object is changed to black, there will be no trailing phenomenon.
In summary, the difference between plasma TVs and LCD TVs can be summarized as follows: LCD TVs have a clear picture, but the brightness is high, the response time is too high, and it is easy to form trailing phenomenon and cause visual fatigue. Plasma TV has the characteristics of clear picture, good dynamic image imaging, soft brightness, and good color reproduction, which can reduce the stimulation of the retina on the TV screen and greatly reduce eye fatigue.
