Plasma television (PDP) is a device which injects mixed gas between two ultra-thin glass plates and applies voltage to make use of phosphor to make light for imaging.

What's the difference between (PDP) (LCD) and (LED) TVs.

compared with LCD.
it has the characteristics of high brightness, high contrast, large viewing angle, bright color and rich interfaces.
plasma is a self luminous display technology.
it does not need background light, Therefore, there is no problem of view angle and brightness uniformity of LCD display, and higher brightness and contrast are achieved.
the design of three primary colors sharing the same plasma tube also avoids the problems of focusing and convergence.
it can achieve very clear images.
compared with LCD display technology.
the larger the plasma screen is, the higher the color depth and fidelity of the image are.
in addition to brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness, brightness In addition to the advantages of contrast and viewing angle,
plasma technology also avoids the response time problem in LCD technology, and these characteristics are the most important factors in dynamic video display.

LCD is commonly known as liquid crystal display.
TFT LCD panel is mainly used in LCD TV.
its main components include fluorescent tube, fluorescent tube and LCD Light guide plate, polarizing plate, filter plate, glass substrate, alignment film, liquid crystal material, thin mode transistor, etc.
first, LCD must use backlight.
that is, fluorescent tubes project light sources, which will first pass through a polarizing plate and then through the liquid crystal, At this time, the arrangement of liquid crystal molecules changes the angle of light passing through the liquid crystal.
then the light must pass through the front color filter film and another polarizing plate.
.
some comparisons between plasma TV and LCD TV: (1) in the screen size.
the screen size of plasma TV is larger than that of LCD TVPlasma TVs are generally not less than 37 inches in size, because it is difficult to squeeze a large number of plasma pixels into smaller screens.
(2) in terms of resolution, plasma TVs are generally not as good as LCD TVs. Moreover, in order to reduce costs, plasma TV manufacturers, Many so-called ed (enhanced definition) models are provided instead of the real high-resolution models.
even the real high-resolution models are provided.
the resolution of plasma TV is relatively low, but analysts point out that at a certain viewing distance, it is not easy for consumers to identify the difference between the two.
.
(3) plasma TV is better than LCD TV in contrast, The contrast ratio of plasma TV is 3000:1 and that of LCD TV is 800:1.
however, in brighter places.
the contrast ratio of LCD TV will be improved, while plasma TV will be worse.
.
(4) in terms of color.
plasma TV can display a variety of colors, But the gap between them is narrowing.
.
(5) in terms of product life, LCD TV is better than plasma TV, the former only needs to replace the backlight bulb, However, when the image color of plasma TV is greatly fading, it must replace the old with the new.
fortunately, plasma TV has also improved in this aspect.
this problem will be obvious only after about 60000 hours of use.
.
(6) in terms of power consumption.
the power consumption of plasma TV is relatively high.
.
LCD is the full name of liquid crystal display Ufb, TFD, STN and other types of LCD can not locate the program input point on the dynamic link library.
the dynamic link library can not locate the program input point on the dynamic link libraryThe structure of LCD is to place a liquid crystal cell between two parallel glass substrates.
TFT (thin film transistor) is set on the lower glass substrate, and color filter is set on the upper glass substrate. The rotation direction of liquid crystal molecules is controlled by the change of signal and voltage on the TFT, According to the different backlight sources,
LCD can be divided into CCFL and led.
.
CCFL.
.
refers to liquid crystal display (LCD) with CCFL (cold cathode fluorescent lamp) as backlight.
.
.
the advantage of CCFL is good color performance.
the disadvantage is high power consumption.
.
LED.
.
.

It refers to liquid crystal display (LCD) with LED as backlight.
generally speaking, it refers to WLED.
.
.
the advantages of LED are small size and low power consumption.
therefore, LED is used as backlight, It can achieve high brightness while being light.
the main disadvantage is that the color performance is worse than CCFL.
therefore, most professional drawing LCDs still use the traditional CCFL as the backlight.
.
many users think that LCD can be divided into LED and LCD.
this understanding is misled by advertisements to some extent.
.
.
the LED display on the market is not the same It is the real sense of the LED display.
exactly speaking, it is the LED backlight LCD, and the LCD panel is still the traditional LCD screen.
In a sense, this more or less contains the nature of fraud! Samsung of South Korea was once judged by the British advertising association to have violated the country's advertising law, because its "ledtv" liquid is suspected to mislead consumers.
for LCD, the most important key is its LCD panel and backlight type, while TFT panel is generally used in the LCD panel on the market, which is the same, The only difference between LED and LCD is that they have different backlight types: LED backlight and CCFL backlight (i.e. fluorescent lamp).
they are diode and cold cathode lamp respectively.
