Description

集成封装显示模组
技术领域
本发明涉及LED显示技术领域,特别是指一种集成封装显示模组。
背景技术
LED显示屏的屏体由多个显示模组拼接而成。集成封装技术是将LED芯片直接封装在LED驱动板上,省去了SMD封装回流环节,采用一次整体封装的技术,实现集成化的一种产品。其具有结构简单、易于实现高密度、高可靠性、低封装成本的技术特点。
如图1所示,传统的集成封装显示模组包括有基板1、驱动IC 2、LED芯片3以及掺杂有黑色素的半透明层4,驱动IC 2贴装于基板1底面,LED芯片3贴装于基板1顶面,半透明层4设置于基板1顶面并包覆LED芯片3。传统的半透明层的材料为环氧树脂、硅树脂、硅胶。
这些材料虽然具有一定的耐热性、疏水性以及绝缘性,但由于LED芯片发光时会产生大量的热量,LED芯片的温度很高,LED显示屏长时间使用后,半透明层会容易老化,疏水性和绝缘性变差,LED芯片容易受潮、沾染灰尘以及受到静电破坏,集成封装显示模组的使用寿命低。
发明内容
本发明要解决的技术问题是根据上述现有技术的不足,提出一种集成封装显示模组,解决了半透明层容易老化、集成封装显示模组使用寿命低的问题。
本发明的技术方案是这样实现的:
集成封装显示模组,包括有基板、驱动IC以及LED芯片,多个所述驱动IC贴装于所述基板底面,多个所述LED芯片贴装于所述基板顶面,还包括有透明层和半透明层,所述透明层设置于所述基板顶面并包覆所述LED芯片,所述半透明层设置于所述透明层顶面,所述半透明层的材料为含氟有机物。
进一步地,所述半透明层通过喷镀工艺得到。
进一步地,所述半透明层的厚度为1-50um。
进一步地,所述半透明层呈哑光效果。
进一步地,所述透明层厚度高于所述LED芯片高度。
进一步地,所述透明层的材料为环氧树脂、硅树脂或硅胶。
采用上述技术方案,本发明的有益效果在于:(1)半透明层的材料为含氟有机物且位于最外层,含氟有机物具有更加优秀的耐热性、疏水性以及绝缘性,能够使集成封装显示模组实现防潮、防尘、防静电功能,避免集成封装显示模组受到破坏,提高集成封装显示模组的使用寿命;(2)半透明层通过喷镀工艺得到,半透明层成型后不产生应力和变形,且良品率高,并且使得半透明层厚度容易控制;(3)半透明层具有一定的透光率,能够遮蔽基板的颜色,使得成封装显示模组表面的颜色一致,解决了封装显示模组表面墨色不一致的问题,同时也降低了亮度,增加了对比度;哑光效果使得灯光成漫反射状态输出,加大了混光性能和增加了观看视角。
