The biggest difference between LCD and led lies in the application of two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light-emitting diodes; The main differences are also derived from the above analysis.
in this paper, the main differences are analyzedFirst, brightness.

What is the difference between full-color LED display and LCD display

the single element reaction speed of LED screen is 1000 times that of LCD screen, and its brightness has more advantages than that of LCD screen. LED screen can be taken care of under strong light, and can adapt to the low temperature of minus 40 degreesSecond, power consumption.
power consumption is the most concerned point. Compared with LCD, the power consumption ratio of LED is about 10:1. In this respect, LED has great advantages.
in this paper, the power consumption of LED is analyzedThirdly, viewing angle.
the angle of LCD display is very limited, which is a very lively and headache problem. As long as the deviation angle is a little larger, you can't see the original color, or even nothing; And LED can provide up to 160 ° It has a great advantage.
from the perspective ofFourth, refresh rate.
LED uses electric energy to convert into light energy and adopts injection principle, so it has higher refresh rate and better video processingFifth, contrast.
at present, the known high contrast LCD display is 350:1, but in many cases, it can not meet various needs, but the LED display can achieve higher and more widely used.
in this paper, the design of LED display is introducedSixth, appearance.
LED is based on light-emitting diodes. Compared with LCD, its display can be thinner.
LED is a kind of light-emitting diodesSeventh, the scope of use.
LED displays are more widely used than LCD displays. They can display all kinds of text, numbers, color images and animation information. They can also play TV, video, VCD, DVD and other color video signals,What's more, multiple displays can be used for network broadcasting.
in this paper, we propose a new method for network broadcastingEighth, service life.
generally, LED display can support about 100000 hours. Under normal circumstances, it can be used for decades, but LCD is much lessNinth, color.
the color of LED screen is more realistic than that of LCD screen, because the color gamut of LED TV is much more than that of LCD.

1. LED display screen: also called electronic display screen or floating character screen.
it is composed of LED dot matrix and ledpc panel.
text, picture, animation and video can be displayed by red, blue and green LED lights, The content can be changed at any time, and all components are display devices with modular structure.
traditional LED display screen is usually composed of display module, control system and power supply system.
the display module is composed of dot matrix composed of LED lights.
it is responsible for light-emitting display; The control system can make the screen display text, picture, video and other contents by controlling the lighting of the corresponding area. The monochrome and two-color screen is mainly used to play text, and the full-color screen is mainly used to play animation; The power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen.
the power supply system is responsible for converting the input voltage and current into the voltage and current required by the display screen2. Liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers.
LCD displays use two pieces of polarizing material.
between them is a liquid crystal solution.
electricity flowing through the liquid rearranges the crystals.
so that light cannot pass through them.
therefore.
each crystal is like a shutter, It can not only allow light to pass through but also block the light.
at present, the technology and information products of liquid crystal display (LCD) are developing towards the goal of light, thin, short and small.
the technology and information products of LCD are developing towards the goal of light, thin, short and smallThe display products with a long history around the computer are no exception.
under the premise of being easy to carry and carry.
traditional display methods, such as CRT image tube display and LED display board, are all subject to factors such as large volume or huge power consumption, However, the development of liquid crystal display technology is just in line with the current trend of information products.
whether it is right angle display, low power consumption, small size, or zero radiation, etc.
