LED display and LCD large screen are common video displays in the market.
LCD display is more used for LCD splicing screen, while LED is more used for video display of commercial advertising and background matching of stage performance.
Let's understand the difference between them.

LED display is the abbreviation of Light Emitting Diode. LED display is composed of many small LED module panels,
Each LED module panel, also known as LED display module, is composed of many LED dot pixel matrices, and the distance between each LED dot pixel is called dot spacing.
Generally, the point spacing below P5 (including P5) is used indoors, and the point spacing below P2 is called small pitch LED display,
For example, P2, P1.875, P1.667, and P1.583 are used in places where indoor viewing distance is relatively close;
The pixel spacing above P5 is often used outdoors, and P8, P10, P16 and other pixel spacing are the specifications of LED display screen often used outdoors.

In terms of clarity and brightness, LED display screen has a much higher refresh rate than LCD display screen, and both clarity and brightness are better than LCD display screen.
And the LED display screen can still be clearly displayed under the strong sunlight, and its screen display brightness will be automatically adjusted according to the outdoor environment brightness to achieve excellent video display effect.
As far as the LED light source is concerned, LED display is an energy-saving and environment-friendly product,
Semiconductor light emitting diode (LED) is an extremely energy-saving and widely used light source at the current technical level. The energy saving effect of LED display is 10 times that of LCD display,
In other words, under the same configuration, LCD consumes 10 times more power than LED.

The LED display screen can reach a large viewing angle of 165 °, and the video display is still clear.
Contrast: the contrast of high-quality LED display can reach 3000:1, while the contrast of high-quality LCD display under the same configuration conditions is only about 350:1,
In other words, LED display screen is nearly 10 times stronger than LCD display screen.

For the splicing of display screen, LED display screen can realize seamless splicing of large screen, and can splice display screens of various shapes according to the needs of the project,
Such as LED special-shaped screen, LED magic square screen, arc, circle, column and polygon, etc.
When LCDs are spliced together, there will be an obvious gap between each LCD module. If the viewing distance is too far, you can still feel nothing,
However, if the viewing distance is slightly closer, the gap of the large LCD screen will be more obvious, and the display effect will be greatly reduced,
Moreover, it is difficult to splice LCD displays into video displays of other shapes,
This is also where LED displays have more advantages than LCD displays.

The LED display screen has a wide range of applications. It can be used for advertising video publicity, indoor and outdoor stage performances, on-site video presentations, video lectures for business meetings, video publicity for the stadium, background matching for major parties, and so on.
LCD display screen is generally used to watch advertisements far away.
Compared with LED display, LCD display has the advantages of lower price and cost than LED display,
This is also the main reason why LCD display cannot be completely replaced by LED display.
