Description
技术领域
本发明涉及对数视力表的技术领域,尤其涉及一种低亮高灰高显示的LED制造工艺。
背景技术
光二极管(Light Emitting Diode,LED)是一种能发光的半导体电子元件,可以将电能转化为光能输出。由于其亮度、光照度较强,且功耗小的缘故,被广泛应用于照明、显示等领域。但是目前的所使用的LED显示屏的出光面为点出光且为光表面,容易产生眩光和反光现象,且显示对比度不高。
发明内容
针对上述技术中存在的不足之处,本发明提供一种制造简单方便的低亮高灰高显示的LED制造工艺。
为了达到上述目的,本发明提供的一种低亮高灰高显示的LED制造工艺,包括步骤:
S1、制作基板时加入黑色原料,使基板成为黑色的基体载体;
S2、将晶片和晶线安装在黑色的基板上,分别进行固晶和焊接;
S3、制作黑色的胶体,并将黑色胶体封装至LED上;
S4、对LED进行烘烤、分光;
S5、对封装完成后的LED进行包装封口。
其中,所述黑色胶体的制作包括步骤:
S1、将环氧主剂的A和硬化剂及催化剂等组成的B按一定比例混合均匀并制作成粉剂;
S2、将制成的粉剂中按一定比例加入纳米等的黑色粉末,再混合均匀制作成黑色的粉剂;
S3、将黑色粉剂按一定的重量称取或分配,放入特定的模具型腔内压铸成圆柱状的胶饼并冷藏保存;
S4、将黑色的圆柱形胶饼解冻至常温经molding工艺封装至LED产品上。
其中,所述基板包括基体、玻璃纤维和环氧胶,环氧胶将玻璃纤维粘接在基体上。
其中,所述晶线全部进行黑色化处理。
与现有技术相比,本发明提供的低亮高灰高显示的LED制造工艺,通过全黑的制造设计,LED发光的正面是全黑的颜色,LED的光源是从一个较黑色的背景后发出光,从而实现LED应用于显示屏时使显示屏的画面具有更鲜明的对比效果和更柔和的视觉效果并且能有很高的对比度。
附图说明
图1为本发明LED的制造流程图;
图2为本发明黑色胶体的制造流程图。
具体实施方式
为了更清楚地表述本发明,下面结合附图对本发明作进一步地描述。
参阅图1,本发明提供的一种低亮高灰高显示的LED制造工艺,包括步骤:
S1、制作基板时加入黑色原料,使基板成为黑色的基体载体;
S2、将晶片和晶线安装在黑色的基板上,分别进行固晶和焊接;
S3、制作黑色的胶体,并将黑色胶体封装至LED上;
S4、对LED进行烘烤、分光;
S5、对封装完成后的LED进行包装封口。
与现有技术相比,本发明提供的低亮高灰高显示的LED制造工艺,通过全黑的制造设计,LED发光的正面是全黑的颜色,LED的光源是从一个较黑色的背景后发出光,从而实现LED应用于显示屏时使显示屏的画面具有更鲜明的对比效果和更柔和的视觉效果并且能有很高的对比度。
参阅图2,在本发明中,所述黑色胶体的制作包括步骤:
S1、将环氧主剂的A和硬化剂及催化剂等组成的B按一定比例混合均匀并制作成粉剂;
S2、将制成的粉剂中按一定比例加入纳米等的黑色粉末,再混合均匀制作成黑色的粉剂;
S3、将黑色粉剂按一定的重量称取或分配,放入特定的模具型腔内压铸成圆柱状的胶饼并冷藏保存;
S4、将黑色的圆柱形胶饼解冻至常温经molding工艺封装至LED产品上。
在本发明中,所述基板包括基体、玻璃纤维和环氧胶,环氧胶将玻璃纤维粘接在基体上,所述玻璃纤维主要是起到承载基体的作用,而环氧胶的功能是将多层玻璃纤维粘接结合在一起,起到增加基板强度的作用。
在本发明中,所述晶线全部进行黑色化处理,增加基板的黑色面积。
以上公开的仅为本发明的几个具体实施例,但是本发明并非局限于此,任何本领域的技术人员能思之的变化都应落入本发明的保护范围。
