Often see someone on the Internet to ask the difference between LCD and LED display, small knitting is here a more comprehensive explanation of LCD and led differences in the end what is it? Manufacturers to promote the LED backlight energy-saving, environmental protection is a gimmick Mody? LED LCD difference is it really that big? Together for you to unlock the difference between the LED and LCD puzzle. Here we will answer with several small points.

One, what is LCD?

LCD is the LCD screen liquid Crystal

Display of the full name, mainly TFT, UFB, TFD, STN, such as several types of LCD display can not locate the program input point on the dynamic link library.

Notebook LCD screen is commonly used in TFT. TFT (Thin Film transistor) refers to the thin film transistor, each liquid crystal pixel is integrated in the pixel behind the thin film transistor to drive, so you can achieve high speed, high brightness, high contrast display screen information, is currently the best LCD color display equipment, is now the mainstream display device on laptops and desktops. Compared with STN, TFT has excellent color saturation, reducing ability and higher contrast, the sun still looks very clear, but the disadvantage is more power consumption, but also higher costs.

Second, what is led?

LED is light-emitting diode light emitting

The English abbreviation of diode. LED applications can be divided into two categories: one is LED display, and the other is led single tube applications, including backlight LED, infrared LED and so on. Now on the LED display, China's design and production technology is basically in sync with the international. LED display is composed by light-emitting diode array of a display device 5000 yuan Computer Configuration list. It adopts low voltage scanning drive, which has the characteristics of less power consumption, long service life, low cost, high brightness, less fault, large angle of view and far distance from visual range.

Three, LCD and led difference

LED display compared with LCD display, led in brightness, power consumption, visual angle and refresh rate, and so on, have more advantages have been canceled to the Web page navigation. Using LED technology, you can create a thinner, brighter, clearer display than the LCD.

1, LED and LCD power consumption than about 1:10,led more energy-efficient.

2, LED has a higher refresh rate, in the video has better performance.

3, led to provide 160° perspective, can display a variety of text, numbers, color images and animation information, you can play TV, video, VCD, DVD and other color video signal.

4, LED display a single element reaction speed is LCD LCD screen 1000 times times, in strong light can also be looked after, and adapt to 零下40度 low temperature.

Simply put, LCD and led are two different display technology, LCD is composed of liquid crystal display, and LED is made up of light-emitting diode display.

Friends, should now understand the difference between LCD and led! So everyone will say that led so good, then I must buy LED display! However, the focus of this article is coming: The current market is not the LED display is the real sense of the LED display, Accurate is the LED backlight LCD display, LCD panel is still the traditional LCD display, in a sense, this number of fraud-containing nature! Samsung, South Korea, has been sentenced by the British Advertising Association as a violation of the country's advertising law, because of its "LEDTV" LCD TV is misleading consumers. For liquid crystal display, the most important key is its LCD panel and backlight type, and the market on the LCD panel is generally used TFT panel, is the same, LED and LCD difference is only their backlight type is different: LED backlight and CCFL backlight (ie fluorescent), Diodes and cold cathode lamps are respectively.

The difference between LED display and LCD display:

LED Backlight: Save electricity (relative to CCFL province electric 30%~50%), high price, bright degree and saturation.

CCFL backlight: Compared to LED backlight power consumption (or a lot more than CRT), cheap.

Screen difference: LED backlight color is more vivid, saturation high (CCFL and led natural light source is not the same).

How to distinguish: LED backlight will be particularly stressed that the LED TV, not the emphasis is CCFL LCD TV

There are still real LED TV (not back light, will be active light-emitting), Sony and Samgsung have, but its panel is currently under 11 inches, and the price is very expensive, like Sony 11-inch AMOLED TV asking about rmB18000, belong to the high-end market, So there are few on the market. Let's take a look at the difference between LCD and led comparison of the actual picture, the following 2 notebook display: The left side for the CCFL backlight LCD, the right for the LED backlight LCD, respectively, red, green, blue contrast under the three colors below figure:

LED display and LCD display color screen contrast

From the picture can be seen, the general naked eye Observation, the LCD screen and LED screen color difference is not very large. If you just pay for the name of the LED is not commensurate with the cost of money, it is not necessary. If you feel that the price is nothing, then this article is completely unnecessary to see, OK this article for everyone to introduce here, I believe that reading this article of the Friends of the LCD display and LED display difference also has a more profound understanding
