Now almost everyone makes a choice in favor of flat panel TVs. Volumetric units occupying half rooms, definitely go away in the past. Flat-screen TVs are produced today using two main technologies: plasma and liquid crystal.
Let's try to understand constructively: is plasma or LCD better? We will bring the scientific basis to dispute.
To date, plasma and LCD are approaching each otherto a friend by basic characteristics. If before the difference between them was quite noticeable, now the LCD gets a bigger diagonal, and the plasma increases the service life. So what is the best plasma or LCD? What to choose for purchase?
LCD and plasma difference
TV on the basis of the liquid crystal display
LCD monitors are based on the following principle of operation. Molecules of liquid crystals under the action of electric current move in space. Light passing through a layer of crystals or delaying them, gets into the light filter. As a result, pixels are displayed, consisting of three sub-labels: green, blue and red. This combination of pixels is able to create a picture on the screen in the usual way.
TV based on the plasma panel
Plasma TVs work on the followingprinciple. All the pixels consist of microlamps with gas (neon and xenon). They are also of three colors (red, green, blue). To the cones containing gas, electrodes supplying voltage are supplied. The voltage level determines the brightness of the glow of the lamps. The plasma image is obtained due to the difference in the degree of illumination of the screen, which creates shades perceived by the eye.
Comparative characteristics of the main parameters
Plasma or what is better?
1. Screen sizes.
Plasma screens are not smaller than 32 inches. The minimum size of the LCD monitor can be compared with the screen of a wristwatch. At the same time to date, LCD panels are already produced in very large sizes, which are almost inferior to plasma. Therefore, you need to choose here based on the size of the room in which you plan to install the TV. Perhaps, LCD on this parameter is more universal.
2. Viewing Angle
The plasma view angle is not less than 170degrees. LCD panels on this indicator, of course, inferior. New LCD models are already approaching the plasma by turning the angle, but the larger the angle, the less contrast is the image. Therefore, one must recognize the advantages of plasma.
3. Speed of the pixel response.
Here, by general parameters, the plasma is leading, inwhich gas discharges act almost instantly. The crystals move more slowly. However, in the latest LCD models, the on time was reduced to 1 millisecond, which resulted in an actual disposal of the image blur.
4. Contrast picture.
Plasma screens give more picturescontrast than LCD monitors. Plasma is characterized by direct radiation, which results in a juicy and bright image. The LCD matrix can simulate the light from the lamps, but do not radiate it. Therefore, the LCD screen image is softer. This is a matter of consumer taste.
5. Even illumination of the panel.
Plasma screens are illuminated evenly bythe identity of all screen cells. In LCD, this effect is more difficult to achieve because of the quality of the backlight. In addition, with greater brightness, LCD monitors lose contrast. The advantage is behind the plasma.
6.Energy consumption.
Plasma consumes energy two times more thanLCD TV. This is due to the problem of heat removal, which requires additional fan operation. In this respect LCD is much more profitable for the consumer.
7. Life time.
Plasma on average is designed for 30 thousand hours, LCD is about 60 thousand. Some manufacturers offer models with the capacity to work up to 100 thousand hours.
Results: plasma or what is better
Plasma wins on moreindicators: safe for health, the image does not flicker, brightness and contrast at a high level, a large viewing angle. The obvious disadvantage is the high energy consumption. LCD panels are more economical because they save electricity. In addition, they are designed for a much longer period of operation and are cheaper when replacing parts.
By and large, now Both technologies are so developed that they practically do not yield to each other in quality. Definitely to say: the plasma or LCD is better - it's difficult. The choice depends on the specific needs of the consumer and subjective preferences.
