The difference between them is that the LED light can be placed on the whole panel, but the LCD light can't, so the brightness of the LED display is more uniform than that of the LCD display, and it's more realistic and vivid to see, while the LED light is more energy-saving, long service life and more durable than the LCD light. thank you.

What is the difference between LED display and LCD display

thank you.
compared with LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate, Both have more advantages.
the power consumption ratio of led to LCD is about 10:1.
moreover, the higher refresh rate makes led have better performance in video, can provide a 160 ° wide viewing angle, can display various text, digital, color images and animation information, and can also play color video signals such as TV, video, VCD and DVD, 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.
it can be looked after under strong light and adapt to the low temperature of minus 40 degrees.
using LED technology, thinner, brighter and clearer displays can be produced, It has a wide range of application prospects.

from another point of view:
totally different concept.
LED is a kind of light-emitting diode, and LCD is a liquid crystal display. There is too much difference between the two. However, the lattice of LED can also be used to form a display, which is suitable for outdoor large screen display with low resolution. LCD is the abbreviation of liquid crystal display, It is a digital display technology, which can filter the light source through liquid crystal and color filter, and generate images on the flat panel.
compared with the traditional cathode ray tube (CRT).
LCD takes up less space,Low power consumption, low radiation, no flicker, reduce visual fatigue.

in the color LCD panel.
each pixel is composed of three LCD cells, in which the front of each cell is red and green respectively, In this way,
light from different cells can display different colors on the screen.
now,
almost all LCDs used in notebook or desktop systems use thin film transistors (TFTs) to activate the cells in the liquid crystal layer.
TFT LCD technology can display more clear.
bright images.

LED light emitting diode The most prominent feature of LED is its long service life.
high photoelectric conversion efficiency.

LED modules are arranged in matrix or pen segment.
prefabricated into standard size modules.
the commonly used are 8x8 lattice modules (64 in monochrome) × One or two primary colors have 64 × In order to improve the brightness, more than two to dozens of LEDs are integrated and packaged into a cluster tube, As a pixel.
this led cluster tube is mainly used for making outdoor screen.
also known as pixel tube.

LED display screen assembles LED modules or cluster tubes into a matrix according to the actual size.
a LED display screen is composed of special display circuit, DC regulated power supply, software, frame and external decoration.
