What is a flat screen TV? What is the difference between a flat screen TV and an LCD TV

A flat-screen TV, as the name suggests, is a flat-panel TV in appearance. From a technical point of view, flat-screen TVs include plasma TVs (PDP), LCD TV(LCD), OLED TV, SED TV, FED TV, and some people count DLP rear projection TVs with a thickness of less than 18 cm as flat-screen TVs. Although there are many categories of flat-screen TVs, the more mature products are still plasma TVs and LCD TVs.

Therefore, this article will also focus on these two types of mainstream flat-screen TVs.

Ion TV (PDP): The so-called plasma color TV refers to filling a mixture of gas between two thin glass plates, applying a voltage to produce ionic gas, and then discharging the plasma gas to react with the phosphor in the substrate to produce a color image.

Advantages (relative to traditional CRT TVs):

The display is small, lightweight, radiation-free, and flicker-free.

2.Since the structure of each emitter element in the PDP is identical, there is no geometric distortion of the image that is common with CRT.

The brightness of the screen is very uniform, with no bright and dark areas; The brightness of the traditional CRT is that the center of the screen is always brighter than the surrounding brightness.

It will not be affected by magnetic fields and has better environmental adaptability.

There is no problem with the screen focusing. As a result, some areas of the CRT can be solved due to poor focus or defocusing over time, and there will be no color drift of the CRT.

6.Surface flatness radically improves distortion and color purity variation in the corners of large screens.

CRT technology is analog technology, and it is expensive to achieve high resolution of HDTV, and it is impossible to achieve a large size of more than 34 inches. The PDP uses completely digital technology and meets all the requirements of HDTV, especially the large screen that can easily be more than 40 inches and less than 10 cm thick.

Cons: 1The plasma display is a flat design, and the glass on the display is extremely thin, so its surface cannot withstand too much or too little atmospheric pressure, let alone unexpected heavy pressure.

Each pixel of the display screen emits light independently,Compared with the use of an electron gun on a CRT TV,Power consumption naturally increases,Generally42The power consumption of a plasma display will be higher than 300W,That is to say, watching a night for 4 hours of TV will cost at least one kilowatt-hour。

3.Due to the high heat generation, there are multiple sets of fans installed on the backplane of the PDP display for heat dissipation, which will have a certain amount of noise.

The panel is the core of plasma,Occupy more than 50% of the cost of the whole TV,The quality of the panel directly affects the service life and display effect of the product。 So remember to ask which panel the manufacturer is using when you buy. At present, the mainstream should be Samsung, LG and Panasonic.

2.Power consumption:The power consumption of the plasma itself is large,Generally300W or more,So the manufacturer will not take the initiative to provide the parameter of power consumption,Considering the high frequency of use of the TV itself,So it is more necessary to choose an energy-saving PDP with a power consumption of about 250W。

Summary. What is the difference between a flat-screen TV and an LCD TV

Hello dear,Flat-screen TV,As the name suggests,It is a TV that looks like a plate,There are currently two kinds of plasma color TV and LCD color TV。 LCD TV is a type of flat-screen TV Plasma TV (PDP) and Liquid Crystal Television (LCD) are both flat screen TVs, they are like twins, although they are very similar on the surface, but they are very different in nature. The biggest difference between the two is that they use different panels, which means that their imaging principles are very different.

Plasma TVs rely on high voltages to activate a special gas in the imaging unit, causing it to produce ultraviolet light to excite phosphorescent substances to emit light. LCD TVs, on the other hand, use an electric current to change the structure of the crystals in the thin-film transistors on the LCD panel, so that it can be visualized. In addition, plasma TVs and LCD TVs also have their own characteristics, such as plasma TVs are cheaper than LCD TVs in the same size, and LCD TVs have advantages in power-saving performance and display resolution Hope it can help you, consultation record · on 2022-05-12

What is the difference between a flat-screen TV and an LCD TV? 1. Flat-panel TV is a flat TV, which is a kind of TV compared with the huge body of the traditional CRT TV, mainly including liquid crystal display LCD, plasma display PDP, organic electroluminescence display OLED, surface conduction electron emission display SED and other major technical types of TV products. 2. LCD TV, also known as LCD TV, is the principle of using liquid crystals to emit light under the action of voltage.
