The polarizer film on the top protects the glass a bit, but it&rsquo;s not up to protecting the display from submersion. Basically, you will need to put the display into some type of enclosure to survive submersion in liquid.<\/p>\n<p>Additionally, the polarizers used on the outside of the <a href=\"https:\/\/www.crystalfontz.com\/blog\/glossary\/lcd\/\" target=\"_self\" title=\"LCD stands for Liquid Crystal Display.

For instance, to&hellip;\" class=\"encyclopedia\">OLED<\/a> are susceptible to absorbing water. For instance, if a drop of water is left on the display, it can turn the polarizer cloudy where the water is absorbed.<\/p>\n<h3>The Key To Safe Waterproofing<\/h3>\n<p>To ensure that the display can be safely submerged in liquid, you need to waterproof <em>all of the electronics<\/em> &mdash; including the display &mdash; inside a case. This is not a simple task, especially if there are keypads or connectors in the design.<\/p>\n<p>For the display, you will want a thin piece of Lexan, or other clear polycarbonite in front of the display that is sealed to the enclosure. Depending on your needs for protection, 0.010 inch to 0.030 inch is the range we suggest.<\/p>\n<h3>It Can Be Done<\/h3>\n<p>Here are examples of mods created by our customers to create water-resistant (metal) and waterproof (plastic) cases for&nbsp;Crystalfontz 633 keypad LCD modules.<\/p>\n<h4>Water-Resistant LCD Housing<\/h4>\n<figure id=\"attachment_453\" aria-describedby=\"caption-attachment-453\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-453 size-large\" src=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-700x284.jpg\" alt=\"Water-Resistant 633 Keypad LCD Housing\" width=\"700\" height=\"284\" srcset=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-700x284.jpg 700w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-250x102.jpg 250w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-768x312.jpg 768w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-120x49.jpg 120w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633.jpg 800w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"><figcaption id=\"caption-attachment-453\" class=\"wp-caption-text\">Water-Resistant 633 Keypad LCD Housing<\/figcaption><\/figure>\n<figure id=\"attachment_454\" aria-describedby=\"caption-attachment-454\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-454 size-large\" src=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2-700x577.jpg\" alt=\"Water-Resistant 633 Keypad LCD Housing\" width=\"700\" height=\"577\" srcset=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2-700x577.jpg 700w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2-250x206.jpg 250w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2-768x633.jpg 768w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2-120x99.jpg 120w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/WaterResistant633-2.jpg 800w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"><figcaption id=\"caption-attachment-454\" class=\"wp-caption-text\">Water-Resistant 633 Keypad LCD Housing &ndash; 2 parts<\/figcaption><\/figure>\n<h4>Waterproof LCD Housing<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"522\" class=\"aligncenter size-large wp-image-455\" src=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept-700x522.jpg\" alt=\"Waterproof 633 Keypad Display Concept Drawing\" srcset=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept-700x522.jpg 700w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept-250x187.jpg 250w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept-768x573.jpg 768w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept-120x90.jpg 120w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633Concept.jpg 800w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"><\/p>\n<figure id=\"attachment_456\" aria-describedby=\"caption-attachment-456\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-456 size-large\" src=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633-700x664.jpg\" alt=\"Waterproof Housing for the Crystalfontz 633 Keypad Module\" width=\"700\" height=\"664\" srcset=\"https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633-700x664.jpg 700w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633-250x237.jpg 250w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633-768x729.jpg 768w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633-120x114.jpg 120w, https:\/\/www.crystalfontz.com\/blog\/wp-content\/uploads\/Waterproof633.jpg 800w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"><figcaption id=\"caption-attachment-456\" class=\"wp-caption-text\">Waterproof Housing for the Crystalfontz 633 Keypad Module<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This is a frequent question for our tech team:\u00a0What displays (if any) are waterproof?
