In 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.
In short, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystal, while LED is a display screen composed of light-emitting diodes.

Is there any difference between LED and LCD

.
     Their light sources are different.
LCD mainly uses CCFL (cold cathode fluorescent lamp) as backlight.
and led tv backlight is led (light emitting diode), each LED pixel lights up according to the brightness of the image, making LED TV more delicate and realistic in display details.
.
next.
after using LED backlight, the volume of LCD panel will be further reduced; LED is composed of many grid like LED, each "grid" has an LED, so that the LED backlight can realize the real light source planarization. The planarized light source not only has excellent brightness uniformity, but also does not need complex light path design. The LCD TV with LED can be made thinner, and the real light source planarization can be realized.
.
this paper introduces the design of the LED light source planarization      In terms of luminous life.
LED backlight technology can surpass the traditional LCD TV.
the service life of ordinary LCD TV backlight is generally about 30000 hours.
even the top LCD TV backlight has a service life of only 60000 hours.
at present, the service life of white LED backlight is as high as 100000 hours.
if the backlight is turned on for 5 hours a day, the service life of white LED backlight is about 60000 hours, A LCD TV with LED backlight can be used for nearly 55 years.
.
the only difference between LED and LCD is the backlight.
the panels are the same.
.
businesses say that.
it's a bit deceptive.
.
the real LED is like the big billboard we see on the wall.

both of their panels are liquid crystal.
also known as TN panel.
.
type of backlight.
LED and CCFL are diode and cold cathode lamp, respectively. You can understand it when you search Baidu.
.
of course, diode is better than other ones.
energy saving, environmental protection, small place, high brightness, Fashion.
.
but the price is more expensive.
.
if you think the two prices are similar.
or buy led, if the difference is too much, you need LCD.
.
LCD is also good.
I think the lamp is softer, and the adjustable range is higher.
.
I think the lamp is more flexible
