At present, when thick kinescope-based televisions are a thing of the past, the question often arises for users: what technology to buy a TV device. Basically, the market is dominated by two models of televisions: plasma and liquid crystal. This article will discuss the pros and cons of both technologies.
First, you should describe the basic ways these two technologies work. LCD monitors are based on liquid crystal molecules that move under the influence of current. These particles either transmit light or delay it, which is why three primary colors are formed in the filter - green, red and blue. It is these colors that create a rich palette of colors on the TV screen.
The plasma panel consists of microlamps that are filled with gas (xenon and neon). Three-color microlamps (also blue, green, red) make up pixels. Electrical voltage changes the brightness of these cones, resulting in a combination of three colors, creating shades of any kind.
What is better than LCD or plasma - comparison criteria
In order to reach a verdict in favor of any one technology, devices should be compared according to different criteria. Such as: Screen size, viewing angle, pixel response speed, image contrast, uniformity of lighting, energy consumption, life. By comparing technologies according to these criteria, the user will be able to conclude what exactly suits him the most.
Screen size
Screen size is an important factor when choosing a TV. Plasma-based televisions are not produced less than 30 inches. At the same time, LCD devices can reach very tiny sizes. At the same time, liquid crystal TVs sometimes reach huge sizes. Plasma devices are not inferior to them in size. Therefore, the LCD wins in this comparison criterion, since this technology is the most universal in size.
Viewing angle
For a plasma model, the viewing angle can reach 160 degrees without loss in brightness or color distortion. LCD TVs, in turn, lose by these parameters. The image contrast is lost with increasing angle at which the user looks at the screen.
Pixel Response Speed
Due to the fact that the crystals need some time to change to the desired position, the LCD technology loses to the plasma competitor. And although modern models of liquid crystal TVs are approaching plasma TVs in response speed, the latter is still ahead of them in this parameter.
Picture contrast
LCD TVs, due to their technology, have a softer picture. At the same time, as a plasma panel emitting light, it is directly characterized by the highest brightness and contrast.
Panel illumination uniformity
Here the situation is similar to the previous comparison. Because of their technology, LCD devices are not able to provide the most uniform illumination of all cells on the screen. Plasma, in turn, ensures uniformity of illumination in full.
Power consumption
The plasma panel, due to its technology, consumes much more energy than LCD devices. This is caused by the possibility of overheating of the flasks, in connection with which, in most TVs, there is a cooling system that requires additional voltage. In liquid crystal technology, this is not required, therefore, these devices are considered more energy-efficient.
Lifetime
A screen based on an average price plasma panel will last up to 30 thousand hours. At the same time, the LCD display of the same price category can last up to 60 hours. Some models can last much longer, however, the price range of such devices will be higher.
Conclusion
By most indicators, plasma technology is gaining up, but it has disadvantages that can alienate many users. Of the advantages of plasma TVs, a large viewing angle, good color reproduction, brightness and contrast can be distinguished. And it should also be noted that such devices are less prone to flicker, which makes them safer during prolonged use. Of the minuses, it is worth noting only the fragility and high energy consumption.
LCD displays are more environmentally friendly and designed for longer life. Of the obvious advantages, it is worth highlighting the relative cheapness and variety of sizes, which plasma panels cannot boast of. However, LCD TVs are inferior in brightness and contrast. Also, such screens may flicker, which may not affect the user's health very well.
The universal answer is that there is no better LCD or plasma. Each technology is good for different purposes. Therefore, the choice is always at the discretion of the user.
