Abstract
本实用新型公开了一种LED电子显示屏用3528RGB三合一LED封装结构的改良,采用两颗9mil红光晶片并联的方式取代了传统采用一颗12mil红光晶片,即两颗9mil红光晶片与一颗蓝光晶片及一颗绿光晶片四者并联固晶封装,两颗9mil红光晶片分别通过底部的银胶导电并通过上层的金线与正极连接,从本实用新型封装成品测试结果来看,本实用新型封装成品红、绿、蓝的亮度比接近于3∶6∶1,因此本实用新型有效克服了红光亮度不足的问题;因为12mil红光晶片的价格一般在150元/k左右,而9mil红光晶片的价格一般在20元/k左右,因此用两颗9mil红光晶片替代一颗12mil红光晶片可以使成本大大降低,可节约成本约1/2。
Description
技术领域
本实用新型涉及一种LED电子显示屏用3528RGB三合一LED的封装结构。
背景技术
目前习用的LED电子显示屏用3528RGB三合一LED(3528RGB是行业术语,3528指封装形式,R、G、B分别指红、绿、蓝)的封装结构如图5所示,采用三晶PLCC支架,分别将红光(辐射波段620~627nm)晶片、绿光(辐射波段520~525nm)晶片和蓝光(辐射波段465~470nm)晶片这三个晶片贴装于三晶PLCC支架的相应固晶位上,通过电流控制实现三原色混光,产生65536×65536×65536种颜色,应用于全彩显示。
由于目前正极性晶片发展的限制与成本应用的考量,目前3528RGB三合一LED混白光呈现红光亮度不足的情形,一般RGB混白光亮度要求比为3∶6∶1,而实际上封装成品亮度比约1.8∶6∶1,红光亮度明显不足,故造成需同时降低蓝、绿光光亮度以达到白平衡。
发明内容
为了克服上述缺陷,本实用新型提供了一种LED电子显示屏用3528RGB三合一LED封装结构的改良,此结构可以有效克服红光亮度不足的问题,同时还可以节约成本约1/2,且结构简单、易于实施。
本实用新型为了解决其技术问题所采用的技术方案是:
一种LED电子显示屏用3528RGB三合一LED封装结构的改良,蓝光晶片固晶位上贴装有一颗蓝光晶片,绿光晶片固晶位上贴装有一颗绿光晶片,所述蓝光晶片与绿光晶片并联且皆与正极电性连接,红光晶片固晶位上贴装有两颗9mil红光晶片,两颗9mil红光晶片并联且皆与正极电性连接,两颗9mil红光晶片与所述蓝光晶片和所述绿光晶片并联。(mil即密耳,指千分之一英寸。)
该LED电子显示屏用3528RGB三合一LED封装结构的改良采用两颗9mil红光晶片并联的方式取代了传统的一颗12mil红光晶片,即两颗9mil红光晶片与一颗蓝光晶片及一颗绿光晶片四者并联固晶封装,两颗9mil红光晶片分别通过底部的银胶导电并通过上层的金线与正极连接。
本实用新型的有益效果是:该LED电子显示屏用3528RGB三合一LED封装结构的改良采用两颗9mil红光晶片并联的方式取代了传统采用一颗12mil红光晶片,即两颗9mil红光晶片与一颗蓝光晶片及一颗绿光晶片四者并联固晶封装,两颗9mil红光晶片分别通过底部的银胶导电并通过上层的金线与正极连接,从本实用新型封装成品测试结果来看,本实用新型封装成品红、绿、蓝的亮度比接近于3∶6∶1,因此本实用新型有效克服了红光亮度不足的问题;因为12mil红光晶片的价格一般在150元/k左右,而9mil红光晶片的价格一般在20元/k左右,因此用两颗9mil红光晶片替代一颗12mil红光晶片可以使成本大大降低,可节约成本约1/2。
