Abstract

本发明公开了一种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，从本发明封装成品测试结果来看，本发明封装成品红、绿、蓝的亮度比接近于3∶6∶1，因此本发明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

LED电子显示屏用3528RGB三合一LED封装结构的改良
技术领域
本发明涉及一种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，本发明提供了一种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。
本发明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。
本发明的有益效果是：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，从本发明封装成品测试结果来看，本发明封装成品红、绿、蓝的亮度比接近于3∶6∶1，因此本发明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。
附图说明
图1为本发明结构示意图；
图2为本发明封装成品测试的蓝光光强变化曲线；
图3为本发明封装成品测试的绿光光强变化曲线；
图4为本发明封装成品测试的红光光强变化曲线；
图5为习用的LED电子显示屏用3528RGB三合一LED封装结构。
具体实施方式
实施例：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3，绿光晶片固晶位上贴装有一颗绿光晶片2，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1，两颗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4导电并通过上层的金线5与正极连接。从本发明封装成品测试结果来看(如图2、3、4所示)，本发明封装成品红、绿、蓝的亮度比接近于3∶6∶1，因此本发明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。
