According to the optoelectronic characteristics of LEDs, the driving voltage of the red LED light is lower than that of the green LED light and the blue LED light. In order to ensure the balance of IC heat generation and the long-term stable operation of the screen, the driving circuit must be adjusted with a peripheral bias circuit.<\/p><p>For example, if the input voltage is 4V, the red lamp&#8217;s voltage drop is around 1.8V, blue and green lamp&#8217;s voltage drop is around 3V. The constant current IC driver also have around 0.7V voltage drop. Hence the red lamp circuit needs to add a resistor to share the voltage drop of the driver IC, while the blue and green circuit do not need.<\/p><p>After using a resistor in the red lamp circuit, The resistor would also consume energy, which would change into heat. Hence the led screen that uses common anode powering would generate more heat (the design should consider heat dissipation carefully) and also be difficult in circuit layout design.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-09f4196 elementor-widget elementor-widget-image\" data-id=\"09f4196\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"622\" height=\"338\" src=\"https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/common-Anode.jpg\" class=\"attachment-medium_large size-medium_large wp-image-5363\" alt=\"common Anode\" srcset=\"https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/common-Anode.jpg 622w, https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/common-Anode-300x163.jpg 300w\" sizes=\"(max-width: 622px) 100vw, 622px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-52ebd5f elementor-widget elementor-widget-heading\" data-id=\"52ebd5f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">What is Common Cathode LED Screen?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8a0bd7f elementor-widget elementor-widget-text-editor\" data-id=\"8a0bd7f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>For common cathode LED Screen, The red lamp is using a different power supplier from blue and green lamp.
