Compared with LCD display, LED display has more advantages in 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 also play TV, video, VCD, DVD and other color video signals. Multiple displays can also be broadcast online. The single element reaction speed of organic LED display screen is 1000 times of that of LCD screen. It can be taken care of under strong light and adapt to the low temperature of minus 40 degrees/
Compared 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.
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.

What is the difference between LED and LCD?

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 handLED is a kind of light-emitting diode, while LCD is a kind of liquid crystal display. There is too much difference between them. However, the dot matrix of LED can also be used to form a display, which is suitable for outdoor large screen display with low resolution. LCD is a kind of digital display technology, which can filter light source through liquid crystal and color filter, Compared with traditional cathode ray tube (CRT).
LCD takes up less space, low power consumption, low radiation, no flicker, and reduces visual fatigue.
LCD can generate images on flat panelIn the color LCD panel,
each pixel is composed of three liquid crystal cells, and there are red, green, or blue filters in front of each cell.
in this way,
different colors can be displayed on the screen through the light of different cells.
in this way, different colors can be displayed on the screenNow.
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 paper, we introduce a new method of TFT LCD technologyThe 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 decorationIt can be seen that of course, the LCD is bright. The LCD display has a good development prospect.
it is a liquid crystal.
it is a flat panel.
