Is a LED monitor a liquid crystal display?
in briefLCD is the abbreviation of LCD liquid crystal display, the light itself only by applying the signal effect of reflected or transmitted light, for TV behind it to have a back light, you see the image back light through an LCD screen backlight. Before most of what the fluorescent lamp, the relative costs of electricity and life is short.LED is the abbreviation of two luminous tubes, which direct light, can make the street through the large screen LED array for TV, it can only do the backlight (volume and heat reason), LED TV is usually used LED as the light source of the LCD TV, the relative power and long service life
Among the consumers of many displays, LCD (Liquid, Crystal, Display) refers to liquid crystal displays; LED generally refers to liquid crystal display using LED backlight. So it's not appropriate to compare the LCD and LED's different classes.In the current market, liquid crystal display is mainly divided into two categories, one is the use of traditional CCFL (cold cathode fluorescent tube) LCD, and the other is the use of LED (LED) backlit lcd. Many consumers directly refer to the first type of monitor as LCD, and the second type of monitor is called LED. If the statement is incorrect, it does exist.Because, for many consumers put forward "LCD and LED difference", in fact, the real comparison is "LED backlit LCD display and the traditional CCFL backlight LCD display" the difference between".At present, LED backlight in the civil display market has greatly replaced the traditional CCFL backlight potential, the following author from the point of view of both advantages and disadvantages to introduce two kinds of backlight.
LCD is talking about liquid crystals, and there are two kinds of back light. They are cathode ray CCFL and led LED, and the two are LCD liquid crystalThese two methods do not have any good or bad in specification, and the effect of imaging is not bigWhen the liquid crystal came out, it was basically CCFL backlight, so I didn't mention it. It was called LCD directlySince LED came out later, it gave a more advanced impression, and it made the screen thinner, which CCFL could not do
