Before the SMD led lamp, led display is using DIP led lamp which means each pixel need 3 led lamp, and this has limited the pixel pitch of the led lamp. The popular pixel pitch at that time was 37.5mm, 50mm, 100mm or even bigger, and as the main application of the led display at that time was outdoor billboard, big concert, as the viewing distance is far, hence the pixel pitch is not a big problem. But when try to use it indoor, due to the shorter viewing distance, it need smaller pixel pitch. And the SMD package at the time made it possible by making pixel pitch 12.5mm, 7.25mm which makes indoor viewing possible. And now SMD led display is still the main stream technology in led display usage.

Leyard made the world\u2019s first pixel pitch 2.5mm led display, and named it <a href=\"https:\/\/tepixel.com\/small-pixel-pitch-led-display-plata-series\/\">small pixel pitch led display<\/a>. And since that time, A new category of led display was born. We call the pixel pitch less than 2.5mm led display a small pixel pitch led display.<\/p><p>At the time, the first small pixel pitch\u2019s price would easily cost 30,000USD\/sqm, And now smaller pixel pitch has dominated the market, and the main steam of the small pixel pitch led display has become pixel pitch 1.25mm. And the price also have dropped like 10times. Which makes the popularity usage of the led display possible.

With the LED lamps\u2019 quantities goes up, and distance between led lamps become short, the consistency of the led lamp becomes a important factor that affect the visual effect of the led display.<\/p><p>Though the led display\u2019s led lamp are all from the same batch, but different led lamp would have slightly difference in color (wavelength) and brightness specs for the Red, Green and Blue lamp. The difference is not that obvious when the distance between the led lamps are big (pixel pitch is big), But the pixel pitch below 2.5mm, the difference would become hard to neglect. Then Calibration technology comes to market.<\/p><p>The theory of the Calibration technology is as below. <br \/>1: It use a camera to capture the brightness of all the led lamps (red, green, blue)<br \/>2: Its software would know the highest brightness a nit, and lowest brightness b nit. then it generate a correction factor for all the led lamp to be able to perform 80% * b nit. ( this correction factor can change current of the led lamp)<br \/>3:Then for all the led lamps (Red, Green, Blue) it would have correction factors, that makes all the led lamp to give brightness 80% *b nit. Then this led screen\u2019s brightness consistency would become good. <br \/>And this is the calibration process. And from above, we would also know that after the calibration, the brightness would the led display would become lower.

Heat dissipation and energy cost is always a big problem for outdoor led display. It is normally that we see the outdoor led display need to use a air condition system to cool it down.<\/p><p>While at 2010, silicon-core has introduce a game changing technology- Common cathode technology that not only reduce the heat, but also reduce the electrical bill. The theory of the Common cathode is as below:<\/p><p>1: Red led lamp\u2019s power voltage is 2.6V, while Green and Blue led lamp\u2019s power voltage is 3.6V. While in common anode technology, all the led lamp are power with the same voltage like 4.8V.<br \/>2: In <a href=\"https:\/\/tepixel.com\/outdoor-led-screen-forta\/\">common cathode technology<\/a>, it would power the red lamp using 2.8V, and power Green and Blue led lamp using 3.8V. This means that for the common cathode technology, it need to have two different voltage input power supplier.<br \/>3:Say the common cathode and common anode is in the same brightness level which means the current that run through the led lamp is same. We would know that the wattage ration between common cathode and common anode is as below:<\/p><p>Common cathode\/common anode = (2.8I + 2*3.8I)\/(4.8*3*I) = 0.722<br \/>Which means that the common cathode can save around 1-0.722=27.8% energy<\/p><p>And less power consumed, also means less heat would generate.<\/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-5c95b6b elementor-widget elementor-widget-image\" data-id=\"5c95b6b\" 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=\"1024\" height=\"519\" src=\"https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode-1024x519.jpg\" class=\"attachment-large size-large wp-image-5350\" alt=\"\" srcset=\"https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode-1024x519.jpg 1024w, https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode-300x152.jpg 300w, https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode-768x389.jpg 768w, https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode-1536x778.jpg 1536w, https:\/\/tepixel.com\/wp-content\/uploads\/2022\/06\/Drawing-of-common-cathode-and-common-anode.jpg 1676w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\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-ea96562 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ea96562\" 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-6c14135\" data-id=\"6c14135\" 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-4acefed elementor-widget elementor-widget-heading\" data-id=\"4acefed\" 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\">8: COB technology come into market at 2019, mini led display and micro led display possible<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0ab75cb elementor-widget-tablet__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"0ab75cb\" 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>Since the debut of the small pixel pitch led display, all manufacturer are all invest in small pixel pitch led display, and the pixel pitch become smaller and smaller. It reached a bottle neck when the pixel pitch near 1.25mm<\/p><p>When the pixel pitch become smaller and smaller, it becomes hard to make SMD package, now the smallest SMD package led lamp is size 1mm, and it is using CHIP structure. And when the package size become smaller, it also means the connecting pad become smaller, which means that the led lamp has less adhesive force on the PCB. Then some factory start to think, why not mount the led chip directly on the PCB, which can avoid the SMD package size and also strong adhesive force for the led lamp.<\/p><p>Many company like Ledman, Cedar, Leyard lunch their COB product at 2019. While for the COB, It do have many problems when it fist come out, as the pixel pitch is small, say pixel pitch 1.25mm. It means that for 1sqm led lamp module, it need to solder 1000\/1.25*1000\/1.25*3=1,920,000 LED chips on the PCB and no mistakes is allowed. This cause a lot of problem into mass production, and this difficult is call mass transfer. And after the mass transfer, it also need to apply a layer on the top of the PCB to protect the LED chip. In the early days, this layer\u2019s consistency is also not good. Hence in the early days of the COB, the visual effect is not good, and also very expensive. While now, as the developments of the technology, COB already have a price advantage and better visual effect comparing with SMD. And the future belongs to COB.<\/p><p>Micro led display is pixel pitch below 1mm, normally made by COB.<\/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-b8c4dea elementor-widget elementor-widget-image\" data-id=\"b8c4dea\" 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=\"1024\" height=\"652\" src=\"https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display-1024x652.webp\" class=\"attachment-large size-large wp-image-13506\" alt=\"COB LED display\" srcset=\"https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display-1024x652.webp 1024w, https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display-300x191.webp 300w, https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display-768x489.webp 768w, https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display-18x12.webp 18w, https:\/\/tepixel.com\/wp-content\/uploads\/2026\/10\/COB-LED-display.webp 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\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-4c57b63 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4c57b63\" 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-3f086cf\" data-id=\"3f086cf\" 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-d33fe67 elementor-widget elementor-widget-heading\" data-id=\"d33fe67\" 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\">9: Flexible led display and creative led display<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-10a1299 elementor-widget-tablet__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"10a1299\" 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><a href=\"_wp_link_placeholder\" data-wplink-edit=\"true\">Creative led display<\/a> is big category, normally as for most creative led display, it need to customized different shape or need a different function.
