11/12/2023 0 Comments High technology indoor outdoor screensThe indoor LED display does not tolerate temperature changes, and they do not have enhanced anti-vandal protection. With the advancement in technology, the brightness of the SMD LED has been dramatically improved, and the waterproof treatment can also be treated well. SMD LED is generally used as a large-screen LED light source for interiors. The LED assembly’s appearance can quickly reduce the material’s weight in half. The SMT LED solves problems like brightness, viewing angle, flatness, reliability, and consistency. The surface mount technology (SMT) is a production method of circuit electronics in which the elements are mounted or set directly on the outside of printed circuit boards (PCBs), and an electronic gadget is manufactured called a surface-mount device (SMD). The packaging is mounted on a printed circuit or inserted into a holder. The dual in-line package is an electronic component package with a rectangular housing and two parallel rows of electrical connection pins. The image looks more lively, attractive than on DIP displays. SMD technology allows pixels to be arranged much denser, which increases picture quality. The latest technologies make it possible to create outdoor LED displays using SMD technology achieved through external sealed housings, the application of unique moisture and dirt-protective films, and parts and elements with a wide operating temperature range. The pixel pitch is the horizontal distance between two pixels. In colored screens, a pixel is formed by three (red, green, blue) or more individual LED elements. Two contacts (legs) extend from the component, for which the part is soldered to a conductive substrate. DIP technology uses each LED element placed in a plastic lens. Initially, outdoor display screens were manufactured exclusively using DIP technology. The interval between two adjacent pixels horizontally is called a pixel pitch. Pixels are placed at equal distances from each other. The red, blue, green LEDs (RGB) are housed in a single housing (pixel), soldered directly into a conductive substrate. The indoor LED screens are manufactured using SMD technology. Internal screens (indoors) are attached to walls, placed on special racks, and suspended on cables. External screens (outdoor) are installed using unique structures such as “legs” fixed on buildings or walls. The outdoor LED display is mainly used in large outdoor areas such as shopping malls, advertising information display boards, commercial streets, and stations.
