How long has the LCD TV been out? It has a small LED backlight. It doesn't have to use the LCD screen. There is no way to compare the two!

Is LCD different from LED TV?

there's no way to compare the two<
LCD is the full name of LCD.
it mainly includes TFT, ufb, TFD, STN and other types of LCD.
.
.
TFT is commonly used in notebook LCD.
TFT screen is thin film transistor.
it is an active matrix LCD. Special light tube is set on its back to actively control each independent pixel on the screen, This is also the origin of the so-called active matrix TFT, which can greatly improve the response time, about 80 ms, effectively improve the flicker blur phenomenon of STN (STN response time is 200 ms), and effectively improve the ability of playing dynamic pictures.
compared with STN.
TFT has excellent color saturation, restoration ability and higher contrast, and can still see very clearly in the sun, However, the disadvantages are relatively power consumption and high cost.

.
Second, the classification and main features of LED.
.
LED is the abbreviation of light emitting diode.
LED applications can be divided into two categories: one is led single tube applications.
including backlight LED, infrared line led, etc; The other is led display.
.
.
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.
LED display is a display device composed of light-emitting diodesIt adopts low-voltage scanning drive.
it has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, long viewing distance and so on.
.
.
thirdly, the main differences between LCD and led.
.
compared with LCD, LED displays have the following advantages: brightness, power consumption, viewing angle and refresh rate, The power consumption ratio of LED and 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.
moreover, the reaction speed of single element of LED display is 1000 times faster than that of LCD screen.
it can be looked after in strong light, And adapt to the low temperature of minus 40 degrees.
using LED technology.
can produce thinner, brighter, clearer display than LCD, has a wide range of application prospects.
.
.
in short.
LCD and LED are two different display technologies, LCD is composed of liquid crystal display, However, LED is a display screen composed of light-emitting diodes.
compared with LCD, LED has more advantages in brightness, power consumption, viewing angle, refresh rate, etc.
