At present, LED displays are widely used in e-cigarettes and are developing in the direction of flexibility, large-screen, and intelligence. At the same time, there are also many challenges, such as cost, screen production yield, etc.
LED 显示屏(Light - Emitting Diode display)是一种通过控制半导体发光二极管的显示方式来呈现各种信息的屏幕,它由一个个微小的 LED 像素点按照一定的规律排列组成,能够显示文字、图形、图像、动画、视频等内容。
值得注意的是,随着带屏电子烟越来越火,数码管的应用也在逐步升级,比如从普通数码管升级为更薄的贴片数码管。
数码管简单来说是由PIN针(引脚)、塑料壳(PC、PPO)、PCB、发光二极管(LED灯珠)、显示面板、固晶胶、高温胶带、封装胶水等组成。原材料购买后由品质进行检验,对各类物料性能和外观检测,合格后入仓上生产线,开启数码管生产之旅。
数码管的常见制造流程是 :穿PIN(insert PIN),固晶(die bonding),焊线(wire bonding),前测/半成品测试(semi-finished testing),灌胶(glue filling),贴标签和盖膜(film pasting),成品检测(finished products testing),包装(wrap)。
2.LED点阵屏与柔性显示
数码管显示较为简单,而要想实现更复杂的显示效果,就需要采用其他LED屏,比如LED点阵屏。
LED 点阵屏中的 LED 是按行列形式排列的。每一行和每一列都分别有对应的导线连接,这些行线和列线用于传输控制信号。通过控制行线和列线的电平高低,可以决定相应位置的 LED 是否发光。
行业中较为热门的星空屏,就是采用LED点阵方案,结合柔性基底,从而实现了柔性显示、酷炫星光等效果。
LED点阵屏的应用实现了电子烟大屏化、柔性显示的功能,但据从业者透露,电子烟LED柔性显示模组的良率有待提高。
