LED is light emitting diode
LED is the abbreviation of light emitting diodeLED applications can be divided into two categories: one is led single tube applications.

What's the difference between LCD and LED screen? Which screen is better

including backlight LED, infrared LED, etc; At present, there is still a certain gap between China and the world in the manufacturing of LED basic materials, but as far as LED display is concerned, China's design and production technology level is basically in line with the international level.
in addition, there is a gap between China and the world in the manufacturing of LED basic materialsLED display is a display device composed of LED arrays.
it is driven by low voltage scanning.
it has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long viewing distance, etc.
it has the advantages of low power consumption, long service life, low cost, high brightness, less faults, long viewing distance, etcCompared with LCD, LED display has more advantages in brightness, power consumption, viewing angle and refresh rate.
the power consumption ratio of led to LCD is about 10:1.
and the higher refresh rate makes led have better performance in video, which can provide up to 160 bandwidth ° It can display all kinds of text, numbers, color images and animation information, and also play TV, video, VCD, DVD and other color video signals. Multiple displays can also be broadcast on the Internet.
the single element reaction speed of organic LED display is 1000 times faster than that of LCD screen.
it can be looked after in strong light, And it can adapt to the low temperature of minus 40 ℃.
LED technology can be used to produce thinner, brighter and clearer display than LCD, which has a wide application prospect.
LED technology can be used to produce a thinner, brighter and clearer display than LCDLCD is the full name of LCD: it includes TFT.
ufb,TFD, STN and other types of LCDTFT is commonly used in notebook LCD screen.
TFT screen is thin film transistor.
English full name (thinfilmtransistor), is an active matrix type of LCD, in its back set special light tube, can actively control each independent pixel on the screen, this is also the origin of the so-called active matrix TFT, this can greatly improve the response time, about 80 ms, and STN for 200 ms! Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, and it can still see clearly in the sun, but the disadvantage is that it consumes more power, and the cost is also higher.
compared with STN, TFT has excellent color saturation, reduction ability and higher contrastIn short,
LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light-emitting diodes.
compared with LCD, LED has more advantages in brightness, power consumption, viewing angle and refresh rate.
LCD can't emit light by itself.
it needs other light sources to emit light (including the sun), The LED can emit light.
the LED can emit lightYour mobile phone is LCD.
the train number information of the railway station is led.
the train number information of the railway station is ledToday's LCD TVs are all LCD.
what the business said about LED is that the backlight used for TV is led.
