OLEDs are used to make OLED Displays, which can either be PMOLED (Passive Matrix OLED) or AMOLED (Active Matrix OLED). Crystalfontz carries a full line of OLED modules.

This fundamental difference is why engineers and designers are increasingly turning to OLEDs to solve complex integration challenges while simultaneously elevating the user experience.<\/p>\n\n\n\n<p>OLED modules have a definite &ldquo;wow factor.&rdquo; While that aesthetic appeal is often reason enough to choose one, there are also deep-seated design and engineering advantages that make them a superior choice for modern electronics. Whether you are navigating tight space constraints or require a display that remains legible in diverse lighting conditions, OLED technology offers a versatile solution.<\/p>\n\n\n\n<p>Working with tight space requirements? Need a highly visible and easy to read display? Consider an OLED module.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">&nbsp;<strong>1) Ultra-Thin Form Factor<\/strong><\/h3>\n\n\n\n<p>Because OLEDs do not require a bulky backlight assembly or diffuser layers, they are incredibly low-profile.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compact Designs: Small displays, such as the <a href=\"https:\/\/www.crystalfontz.com\/product\/cfal12836a0088-128x36-small-oled-display\">CFAL12836A0-088<\/a>, can be less than 1.3mm thick.<\/li>\n\n\n\n<li>Standard Modules: Even larger displays like the <a href=\"https:\/\/www.crystalfontz.com\/product\/cfal12864ky-128x64-small-oled-display\">CFAL12864K-Y<\/a> typically stay under 2.5mm. This allows for sleeker handheld devices and more room for batteries or other internal components.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2) Infinite Contrast Ratios<\/strong><\/h3>\n\n\n\n<p>OLEDs deliver &ldquo;true blacks.&rdquo; In a traditional <a href=\"https:\/\/www.crystalfontz.com\/blog\/glossary\/lcd\/\" target=\"_self\" title=\"LCD stands for Liquid Crystal Display.

OLEDs eliminate this issue. These small but mighty displays offer a viewing angle approaching <strong>180&deg;<\/strong>, ensuring that the data remains legible even when the user isn&rsquo;t looking at the device head-on.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4) Emissive Efficiency<\/strong><\/h3>\n\n\n\n<p>OLEDs are <strong>emissive displays<\/strong>, meaning they generate their own light.
