LED applications can be divided into two categories: one is led single tube applications, including backlight LED, infrared 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. However, as far as LED display is concerned, China's design and production technology level is basically synchronized with the international level.

What is the difference between LED display and LCD screen?

in addition, there is a gap between China and the world in the manufacturing of LED basic materialsThe brightness of LED backlight screen is evenly divided.
the brightness of LCD screen is high, and the LCD screen is traditionally illuminated by the lamp at the bottom of the white backlight board. The brightness of the lamp determines the brightness of the screen. Because the lamp is produced by several different manufacturers, the brightness of the screen is different. This is a normal phenomenon, and the closer it is to the lamp, the brighter it isThe single element reaction speed of organic LED display screen is 1000 times faster than that of LCD screen.
it can be taken care of under strong light, and can adapt to the low temperature of minus 40 ℃The LED screen is generally thin.
the LCD screen should be thicker (not the thickness of the screen frame, but the actual thickness of the middle and upper cover). The LED screen is a display device composed of LED arrays.
it adopts low voltage scanning drive.
it has the following characteristics: low power consumption, long service life, low cost, high brightness, less faults, large viewing angle, long viewing distance, etc.
the LED screen is a kind of display deviceThe 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 on the Internet.

What's the difference between LED display and LCD display: LCD is a display transistor, which is also called liquid crystal display.
LCD display has high resolution. If LED is applied to the display, it is only used as backlight. It can not be used as normal display. LCD display can be very easy and clear. LCD occupies small space, low power consumption, low radiation and no flicker, Reduce visual fatigue.
LED screen is composed of more than n light-emitting diodes.
most of the applications of LED are outdoor advertising display screen (we usually see a large TV like screen on the road). LED lattice can also form a display with low resolution.
in color LCD panel.
each pixel is composed of three liquid crystal cells, Each cell is preceded by red and green, 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 clearer.
bright images.
LED light emitting diode The most prominent feature of LED is its long service life.
high photoelectric conversion efficiencyThe LED modules are arranged into matrix or pen segments.
prefabricated into standard size modules.
the commonly used modules are 8x8 lattice modules (64 for monochrome) × One or two primary colors have 64 × Two light-emitting diodes).
8-word seven segment digital module.
to improve the brightness of the LED cluster tube.
theThis kind of LED tube is mainly used for making outdoor screen.
also known as pixel tube.
LED display panel assembles and arranges LED modules or tubes into a rectangular array according to the actual size.
it is equipped with special display circuit, DC regulated power supply, software, frame and external decoration, That is to say, a LED display screen will be formed.
