LED screen is an advertising medium, an electronic screen that uses semiconductor LEDs as a light source. LED stands for light emitting diode. The first LED screens were published in Japan and North America. These screens, which were initially used in stadiums and sports fields, later took their places on the city streets. The first true LED display (monochrome, for TV) was launched in 1977 by J.P. It is believed to have been developed and demonstrated by Mitchell. In the 21st century, organic light emitting diode (OLED) displays with very small dimensions have become widespread.






LED displays have a wide variety of information display capabilities. It allows display of dynamic advertising, beacon-graphic information, black-and-white and color videos, as well as display temperature, date and current time. The source of the video signal for the LED screen can be a VCR, TV set, computer. The LED screen can usually be controlled by a Windows computer.






Operating System of LED Displays


It includes the LED display operating in conjunction with the control unit, as well as a mounting frame for mounting the LED display modules. The module is a sealed, dustproof and waterproof case with light-emitting matrices mounted on its front surface and has the following; inside are a controller and a power supply, a power connector on the back panel, information connectors, indicators that show service information about the health of the module and its operating mode, as well as handles for moving and installing / removing the module.






Several LEDs form a display cell called pixel which is responsible for color reproduction and brightness in the design of the LED module. It is a basic point consisting of three primary colors (R-red, G-green, B-blue), on which a full color image is written with the help of a pixel. Pixels are combined into modules that make up the LED display. LEDs on large screens match the pixels. Just like on a regular TV. Although every pixel is noticed when looked closely, at long distances these pixelsare not noticed and form a quality whole.






There are many Rental LED Displays, which can be deivided into many types like Indoor Rental LED Display, Outdoor Rental LED Display, Fixed LED Display, Indoor Fixed LED Display, Outdoor Fixed LED Display, Fine Pitch LED Display, HD Fine Pitch LED Display, Ultra Fine Pitch LED Display, Front Service Led Display and so on.






It seems as if modern displays have all kinds of different labels: high definition, 3D, smart, 4K, 4K Ultra, the list goes on. The two most common labels are LCD and LED. What's the difference between the two? Is there a difference? And does this difference make one or the other preferable for certain types of activities like gaming or graphic design?






Are LED and LCD the same thing?


All LED monitors are LCD monitors. But not all LCD monitors are LEDs. Kind of like all eagles are birds, but not all birds are eagles. While the names might be confusing to those wading through specs to find the best monitor, once you break it down it's easier to understand than you think.






We'll explain the tech and the naming conventions, and then highlight some HP monitors that might be the perfect fit for your needs. Let's figure out exactly what LCD and LED monitors are and how to pick the right one for you.






Both types of displays use liquid crystals to help create an image. The difference is in the backlights. While a standard LCD monitor uses fluorescent backlights, an LED monitor uses light-emitting diodes for backlights. LED monitors usually have superior picture quality, but they come in varying backlight configurations. And some backlight configurations create better images than others.
