In the beginning of the led display, it did not have driving IC that designed for led display, and the led lamp used was also in DIP package. Based on the driving IC and the DIP package at that time, common anode is a good solution.<\/p><p><strong><b>SMD led display era:<\/b><\/strong><\/p><p>Before 2011, With the development of the led display industry, special designed IC for led display is coming out, and to make it compatible with the DIP package, the driving IC is designed for common anode use.

And with the bigger quantities of common anode technology used, the price of the common anode led lamp and driving IC decrease very fast which stimulates this market to grow bigger<\/p><p><strong><b>Heat dissipation and power consumption Problem<\/b><\/strong><\/p><p>Before 2018, the led display is not what it is as today, especially for outdoor led display. LED displays generate a lot of heat, and also consume a lot of energy. Normally for a LED display, we would need to install an AC to cool it down, And the led display cabinet would have fan to ventilate. Of course, the design of the LED display do a lot of help, but so does the common Cathode.<\/p><p>As we mentioned above, in order to make the common cathode, you need to customize common cathode RGB led lamp, and also customize common cathode IC. The beginning of the Common cathode technology begins in 2011 when siliconcore designed their own driving IC, and their own common cathode RGB led lamps. This takes a lot of courage, and it also did pay off.<\/p><p>By using Common cathode, it generate less heat, and then use less power.\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-7c78824 elementor-widget elementor-widget-image\" data-id=\"7c78824\" 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=\"768\" height=\"306\" src=\"https:\/\/tepixel.com\/wp-content\/uploads\/2024\/07\/Common-anode-amd-Common-cathode-IC-768x306.webp\" class=\"attachment-medium_large size-medium_large wp-image-11219\" alt=\"Common anode amd Common cathode IC\" srcset=\"https:\/\/tepixel.com\/wp-content\/uploads\/2024\/07\/Common-anode-amd-Common-cathode-IC-768x306.webp 768w, https:\/\/tepixel.com\/wp-content\/uploads\/2024\/07\/Common-anode-amd-Common-cathode-IC-300x120.webp 300w, https:\/\/tepixel.com\/wp-content\/uploads\/2024\/07\/Common-anode-amd-Common-cathode-IC-1024x408.webp 1024w, https:\/\/tepixel.com\/wp-content\/uploads\/2024\/07\/Common-anode-amd-Common-cathode-IC.webp 1334w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\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\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-a6a03b9 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a6a03b9\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-9e2e2a7\" data-id=\"9e2e2a7\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8f48eb6 elementor-widget elementor-widget-heading\" data-id=\"8f48eb6\" 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\">How much energy does common cathode save comparing with Common anode<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5269428 elementor-widget elementor-widget-text-editor\" data-id=\"5269428\" 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>It has R,G,B three lamp in 1 pixel, but the conducting voltage of the Red lamp is around 1.8v, while the conducting voltage of the Green lamp and Blue lamp is around 2.6V. \u00a0And the white balance brightness R:G:B ratio is 3:6:1.

This is because if using common anode, you have a very wide driving IC selection, and as currently the common cathode driving IC\u2019s performance is still not as good as common anode Driving IC. For example, Based on the LED boards\u2019s original design, if it is the common anode design, the default driving IC is ICND1065ap with refresh rate of 3840Hz, if I do not like its performance, then I can change its IC to ICND2165 to reach a better greyscale visual effect, or even upgrade to ICND3065 to reach 7680Hz. But if you are using common cathode, the Driving IC\u2019s selection is very narrow.
