This is the number to pay attention to if you are going to use your screen for static images such as graphic design or photo editing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the other hand, the dynamic contrast is a convenient measure used by manufacturers and it measures the variation of a pixel from black to white (or between greys) in a period of time. This figure does not depend on hardware, as is the case with real contrast, but on software algorithms and image treatments. The figure is usually much higher than the real contrast (for example 20000: 1, 50000: 1, 100,000: 1 or even higher). The dynamic contrast ratio is a relative measure, but it can be useful to predict how good the contrast can look in moving images.<\/p>\n\n\n\n<div class=\"wp-block-ugb-spacer ugb-spacer ugb-846b7f8 ugb-spacer--v2 ugb-main-block\"><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-spacer--inner\"><\/div><\/div><\/div><\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"670\" height=\"292\" src=\"https:\/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN.jpg\" alt=\"\" class=\"wp-image-66293\" title=\"\" srcset=\"\/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN.jpg 670w, \/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN-300x131.jpg 300w, \/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN-24x10.jpg 24w, \/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN-34x15.jpg 34w, \/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN-48x21.jpg 48w, \/\/visualled.com\/wp-content\/uploads\/2022\/04\/contrast-EN-600x261.jpg 600w\" sizes=\"auto, (max-width: 670px) 100vw, 670px\" \/><\/figure>\n<\/div><\/div><\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"alignfull wp-block-ugb-container ugb-container ugb-4f981e1 ugb-container--v2 ugb-container--design-plain ugb-main-block ugb--has-custom-content-width ugb-main-block--inner-center ugb--has-block-background\"><style>.ugb-4f981e1.ugb-container > .ugb-inner-block{max-width:1440px !important}.ugb-4f981e1{padding:0 !important}@media screen and (min-width:768px){.ugb-4f981e1.ugb-container{padding-top:20px !important;padding-right:0px !important;padding-left:0px !important}}<\/style><div class=\"ugb-inner-block ugb-inner-block--center\"><div class=\"ugb-block-content\"><div class=\"ugb-container__wrapper ugb-4f981e1-wrapper\"><div class=\"ugb-container__side\"><div class=\"ugb-container__content-wrapper ugb-4f981e1-content-wrapper\">\n<h2 class=\"wp-block-heading\">BLACK LED CONTRAST IN LED SCREENS, IS IT BETTER?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><strong><a href=\"https:\/\/visualled.com\/en\/led-screen-indoor\/\">Indoor LED screens<\/a>\u00a0have been designed with SMD LEDs that are commercially called Black LED <\/strong><\/strong>(there are other trade names), where the coating resin has been tinted in a black or a dark tone.\u00a0Due to this, the contrast of darker images is increased.
