LCD TV also has the characteristics of flicker-free image, thin thickness and light weight, and LCD screen has been widely used in PC field. However, liquid crystal technology lags behind plasma in the aspect of large screen, and large-screen color TV is expensive and easily influenced by viewing angle.
Size/price ratio
LCD TV and plasma TV are not cheap. Relatively speaking, the unit price per square inch of plasma TV is better than that of LCD TV. From the perspective of home appliance stores in 2009, the size of LCD TV is 22-65 inches, and the price is 2000-80000; Mainstream plasma products are large screens, with the size of 40-58+ inches (Panasonic has 580,000 products 103 inches), and the price of mainstream products is within 80,000 to 40,000.
perform
In terms of home theater effect, plasma TV is better than LCD TV. Experts explained that because LCD TVs usually can't display the blackness of plasma TVs. Therefore, it is difficult for LCD TV to display more details, and video players will feel that the "three-dimensional" sense of the image is not very good.
Life/power consumption
In terms of service life, LCD TV has obvious advantages over plasma TV. Although the life span of plasma TV is different, it takes about 20,000 hours for the brightness to drop to half, and it can drop to half after 50,000 hours for LCD. The power consumption of LCD is only 1/3 of that of plasma TV, and the power consumption of some plasma products is as high as 400 watts/hour.
Screen burning and altitude problems
"Screen burning" is a problem of plasma TV. If a still image remains on the screen for a long time, the "ghost" of the image will remain on the screen. If the TV station logo or news scroll bar is displayed up and down for a long time, or TV programs in standard format are often watched on a wide screen, shadows on the image side will appear up and down or on both sides of the screen. Therefore, it is best to pay attention in use, such as not playing still images on the screen for a long time, and setting the contrast below 50%.
In addition, plasma TV may have problems at high altitude, because the pressure difference at different altitudes will make plasma TV emit unpleasant buzz. Of course, Nanjing will not have the problem of high altitude. LCD TV will not have the above two problems.
Very vivid
Most plasma TVs and LCD TVs can display high-definition signals. However, it should be noted that in order to enjoy a truly complete HDTV, the resolution of the display should be at least 1280×720. Only a few 42-inch plasmas can achieve this resolution, and most 50-inch plasma TVs and almost all LCD TVs larger than 26 inches have no problem. Of course, a TV smaller than 42 inches is not much different from a real HDTV unless you sit in front of the screen and watch it carefully. For example, Panasonic's TH-42PA20U 42 inch plasma TV only provides enhanced resolution (EDTV, 852×480), but the effect of receiving HDTV with it is still very good.
Computers and video games
Most plasma TVs and LCD TVs can be used as computer monitors, and many TVs even provide DVI interfaces for better display performance. There is nothing wrong with the TV and the game console. From the performance point of view, it is difficult to make a decision on the two technologies, but considering the possibility of screen burning of plasma TV, LCD TV is a safer choice.
