LCD is a liquid crystal display
LCD is a liquid crystal displayLEDs are light emitting diodesCompared with LCD display, 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.

How to distinguish led and LCD screen

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 LCDOn the other handThe concept of LED is totally different.
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 form a display, which is suitable for outdoor large screen display with low resolutionLCD is the abbreviation of liquid crystal display, which is a kind of digital display technology. It 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 occupies less space, has low power consumption, low radiation, no flicker, and reduces visual fatigueEach pixel in the color LCD panel is composed of three liquid crystal cells, and each cell has a red, green, or blue filter in front of it.
the color LCD panel is composed of three liquid crystal cellsIn this way.
different colors can be displayed on the screen through the light of different cells.
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.
in this way, the color of the LCD can be displayed through the light of different cellsThe abbreviation of LED light emitting diode (LED).
it is widely used in daily life.
for example, the indicator light of home appliances, automobile rear fog light, etc.
the most significant feature of LED is its long service life.
high photoelectric conversion efficiency.
it has a long service lifeThe LED modules are arranged in matrix or pen segments.
prefabricated into standard size modules.
the commonly used ones are 8x8 dot matrix modules (64 for monochrome) × One or two primary colors have 64 × Two light-emitting diodes).
8-word seven segment digital moduleIn order to improve the brightness.
increase the viewing distance, two or more to dozens of LEDs are integrated and packaged into a bundle tube as a pixel.
this kind of LED bundle tube is mainly used for making outdoor screens.
also known as pixel tube.
this kind of LED bundle tube is mainly used for making outdoor screensThe LED display screen is composed of LED modules or cluster tubes assembled 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
