应用于显示屏的LED发光材料有以下几种形式：
There are several forms of LED light-emitting materials applied to display screen:
① LED发光灯（或称单灯）  一般由单个LED晶片，反光杯，金属阳极，金属阴极构成，外包具有透光聚光能力的环氧树脂外壳。可用一个或多个（不同颜色的）单灯构成一个基本像素，由于亮度高，多用于户外显示屏。
① LED light-emitting lamp (or single lamp) is generally composed of a single LED chip, reflective cup, metal anode and metal cathode, and is wrapped with an epoxy resin shell with light transmitting and concentrating ability. One or more (different color) single lights can be used to form a basic pixel. Because of its high brightness, it is mostly used for outdoor display.
② LED点阵模块  由若干晶片构成发光矩阵，用环氧树脂封装于塑料壳内。适合行列扫描驱动，容易构成高密度的显示屏，多用于户内显示屏。
② LED lattice module is composed of several chips, which are encapsulated in plastic shell with epoxy resin. Suitable for row and column scanning drive, easy to form high-density display screen, mostly used for indoor display screen.
③ 贴片式LED发光灯（或称SMD LED）  就是LED发光灯的贴焊形式的封装，可用于户内全彩色显示屏，可实现单点维护，有效克服马赛克现象。
③ SMD LED (SMD LED) is the packaging of LED light-emitting lamp, which can be used for indoor full-color display screen to achieve single point maintenance and effectively overcome mosaic phenomenon.
