Micro-LED一般为单色的,目前没有彩色的Micro-LED显示模组,如果要实现Micro-LED显示模组发彩色的光,则需要将不同颜色的Micro-LED批量、多次转运到电路基板上。然而,上述转运技术难度非常大,且精度上面更难以控制,产品良率非常差,无法量产。
【发明内容】
基于此,本发明提供一种制作彩色Micro-LED的方法、显示模组及终端,能够在不需要实施转运技术的情况下实现Micro-LED彩色发光。
为解决上述技术问题,本发明采用的一个技术方案是:一种制作彩色Micro-LED的方法,该方法包括以下步骤:
提供基板,所述基板一侧具有多个蓝光Micro-LED的阵列;
使所述蓝光Micro-LED的阵列与第一颜色光敏溶液接触;
点亮所述蓝光Micro-LED的阵列中的第一预设蓝光Micro-LED,使得所述第一预设蓝光Micro-LED上反应聚成透镜;
使所述蓝光Micro-LED的阵列与第二颜色光敏溶液接触;
点亮所述蓝光Micro-LED的阵列中第二预设蓝光Micro-LED,使得所述第二预设蓝光Micro-LED上反应聚成透镜。
本发明通过将Micro-LED的阵列中蓝光Micro-LED先后与不同的颜色的光敏溶液接触,在接触第一颜色光敏溶液后,点亮第一预设蓝光Micro-LED,此时被点亮的第一预设蓝光Micro-LED200发蓝光,使其与第一颜色光敏溶液发生作用,反应聚成透镜,进而使得第一预设蓝光Micro-LED能够发出第一颜色的光。在接触第二颜色光敏溶液后,点亮第二预设蓝光Micro-LED,此时被点亮的第二预设蓝光Micro-LED发蓝光,使其与第二颜色光敏溶液发生作用,也使其反应聚成透镜,使得第二预设蓝光Micro-LED能够发出第二颜色的光。在此基础上,再与剩下的没有点亮,且没有与第一颜色或第二颜色溶液反应聚成透镜的蓝光Micro-LED,即发蓝光的部分蓝光Micro-LED构成三种颜色,进而实现Micro-LED发彩色的效果。
本发明还提供一种显示模组,其包括以上方法所制得的Micro-LED阵列。
本发明还提供一种终端,其包括以上所述的显示模组。
本发明中的具有Micro-LED的阵列可以根据显示模组和终端的大小设置不同的规格,设置相应匹配数量的Micro-LED,实现发彩光的同时巧妙地避免了现有技术实现Micro-LED发彩色光需要批量转运的工序,进而大大提高产品的良率,保证产品的性能。

【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
请参阅图1,为本发明制作彩色Micro-LED的方法的一实施例方式的流程示意图。该方法包括:
S101:提供基板10,基板10一侧具有多个蓝光Micro-LED400的阵列20。
以上基板10可以是以蓝宝石,或者矽,或者碳化矽三种材料的一种或者多种制成。结合图2,该基板10上分布有多个可发蓝光的Micro-LED400形成阵列20,基板上的蓝光Micro-LED400分类三类,分别为第一预设蓝光Micro-LED100、第二预设蓝光Micro-LED200,以及蓝光Micro-LED300。
S102:使蓝光Micro-LED400的阵列20与第一颜色光敏溶液接触。
使蓝光Micro-LED400的阵列20与第一颜色光敏溶液接触,具体的接触方式可以是蓝光Micro-LED400的阵列20浸入溶液,或者将溶液喷涂在蓝光Micro-LED400的阵列20上,或者是其他能使光敏溶液与蓝光Micro-LED400的阵列20接触的方式。
S103:点亮蓝光Micro-LED400的阵列20中的第一预设蓝光Micro-LED100,使得第一预设蓝光Micro-LED100上反应聚成透镜。
结合图3,使蓝光Micro-LED的阵列20中的第一预设蓝光Micro-LED100发亮,进而使第一预设蓝光Micro-LED100上反应聚成透镜。经过该步骤处理形成的第一预设蓝光Micro-LED100能够发第一颜色的光。具体的,在聚成透镜后,透镜上形成第一颜色的色素。更具体的,透镜形成过程为:当Micro-LED100发亮时,触发光敏溶液中的树脂成分发生聚合,在Micro-LED100表面形成光敏树脂核,然后随着基板10缓慢上升,光敏树脂核表面还会形成光敏树脂滴液,待光敏树脂核和光敏树脂滴液固化即形成透镜。
S104:使蓝光Micro-LED400的阵列20与第二颜色光敏溶液接触。
具体的该步骤中二者接触的方式与S102步骤中列举的一样,此不赘述。
S105:点亮蓝光Micro-LED400的阵列20中第二预设蓝光Micro-LED200,使得第二预设蓝光Micro-LED200上反应聚成透镜。
结合图4,使蓝光Micro-LED400的阵列20中的第二预设蓝光Micro-LED200发亮,进而使第二预设蓝光Micro-LED200上反应聚成透镜。经过该步骤处理形成的第二预设蓝光Micro-LED200能够发第二颜色的光。具体的,在聚成透镜后,透镜上形成第二颜色的色素。
以上实施方式中Micro-LED的阵列20中蓝光Micro-LED400先后与不同的颜色的光敏溶液接触,在接触第一颜色光敏溶液后,点亮第一预设蓝光Micro-LED100,此时被点亮的第一预设蓝光Micro-LED100发蓝光,使其与第一颜色光敏溶液发生作用,反应聚成透镜,进而使得第一预设蓝光Micro-LED100能够发出第一颜色的光,同时第一预设蓝光Micro-LED100之外的其他Micro-LED不会与第一颜色光敏溶液反应。在接触第二颜色光敏溶液后,点亮第二预设蓝光Micro-LED200,此时被点亮的第二预设蓝光Micro-LED200发蓝光,使其与第二颜色光敏溶液发生作用,也使其反应聚成透镜,同时第二预设蓝光Micro-LED200之外的其他Micro-LED不会与第一颜色光敏溶液反应,使得第二预设蓝光Micro-LED200能够发出第二颜色的光。在此基础上,再与剩下的没有点亮,且没有与第一颜色或第二颜色溶液反应聚成透镜的蓝光Micro-LED300,即发蓝光的部分蓝光Micro-LED300构成三种颜色,进而实现Micro-LED发彩色的效果。
可选地,第一颜色、第二颜色分别是红色、绿色,第一预设蓝光Micro-LED100上反应聚成透镜后,形成红色像素,第二预设蓝光Micro-LED200上反应聚成透镜后,形成绿色像素。此时三种颜色构成彩色的三原色,通过控制以上红、绿、蓝三种颜色的深浅即可制成各种彩色的Micro-LED。
可以理解的,在其他实施例中,第一颜色也可以为绿色,第二颜色为红色,即第一预设蓝光Micro-LED100上反应聚成透镜后,形成绿色像素,第二预设蓝光Micro-LED200上反应聚成透镜后,形成红色像素。
可选地,每一第一预设蓝光Micro-LED100周围均设有第二预设蓝光Micro-LED200及蓝光Micro-LED300。采用这样的分布,经过步骤S102、S103、S104和S105之后第一预设蓝光Micro-LED100可发红光(或绿光),第二预设蓝光Micro-LED200可发绿光(或红光),再结合发蓝光的蓝光Micro-LED300,即可定义一个红绿蓝三原色构成的像素。基板一侧具有多个以上所述的像素,进而实现整个基板的Micro-LED发彩色的效果。
请参阅图5,为本发明制作彩色Micro-LED的方法的另一实施例方式的流程示意图。该方法包括:
S201:提供基板10,基板10一侧具有多个蓝光Micro-LED400的阵列20。
S202:将蓝光Micro-LED400的阵列20发光面朝下浸入第一颜色光敏树脂溶液中。
蓝光Micro-LED400的阵列20发光面朝下浸入以基板10具有Micro-LED的一侧平齐即可,这样可以保护基板10另一侧的电路。可选地,蓝光Micro-LED400的阵列20发光面朝下浸入一部分也可以,只要能与光敏树脂溶液反应形成透镜即可。可以理解的,在其他实施例中,在电路密封性良好的情况下也可以是蓝光Micro-LED400的阵列20发光面朝上,将整个基板10浸入第一颜色光敏树脂溶液中。
S203:通过一控制电路通入电流使第一预设蓝光Micro-LED100发光,使第一颜色的像素进行光反应在第一预设蓝色Micro-LED100上聚成透镜。
该步骤中,只有第一预设蓝光Micro-LED100通电发光,第二预设蓝色Micro-LED200和其他剩余的蓝色Micro-LED300均没有通电。可以理解的,在其他实施例中,也可以通过其他方式点亮第一预设蓝光Micro-LED100,比如蓄电池或者太阳能等。可选地,该步骤中的电流小于30mA。
S204:将蓝光Micro-LED400的阵列发光面朝下浸入第二颜色光敏树脂溶液中。此步骤的做法与步骤S202类似,此不赘述。

可以理解的,控制电路包括第一控制电路和第二控制电路,第一控制电路连接第一预设蓝色Micro-LED100,第二控制电路连接第二预设蓝色Micro-LED200。第一控制电路连接基板10一侧上的所有第一预设蓝色Micro-LED100,第二控制电路连接基板10一侧上的所有第二预设蓝色Micro-LED200。
可选地,第一颜色光敏树脂溶液和第二颜色光敏树脂溶液均包括光敏树脂,还包括荧光粉和/或量子点颜料。进一步,光敏树脂包括光敏引发剂,还包括树脂单体、预聚物、助剂及用于树脂改性的纳米颗粒中的任意一种或几种的组合。
优选地,由于量子点颜料具有很好的光稳定性,因此量子点颜料的荧光强度比其他荧光粉的发光强度均高,例如其比最常用的有机荧光材料“罗丹明6G”高20倍,它的稳定性是“罗丹明6G”的100倍以上。因此,较荧光粉而言采用量子点颜料制作的显示模组发光效率高,色彩饱和度更好。
其次,由于量子点颜料具有宽的激发谱和窄的发射谱。使用同一激发光源可以激发几个电子,因此大大提高蓝光的转化效率。
可选地,光敏引发剂重量含量小于等于5%。
可选地,荧光粉和/或量子点颜料的含量为1%-1.5%。
可选地,在其他实施例中,在步骤S203和/或S205之后还可以包括:通过控制电路通入电流使第一预设蓝光Micro-LED100和/或第二预设蓝光Micro-LED200再次发光,使得其上的光敏树脂核及光敏树脂滴液进一步固化形成透镜。具体的,步骤中的电流大于30mA。
参见图6,本发明还提供一种显示模组30,其包括如以上任一实施方式中的方法所制得的具有Micro-LED400的阵列20。
参见图7,本发明还提供一种终端40,其包括以上所描述的Micro-LED阵列的显示模组30。本发明提供的显示模组30和终端40中的Micro-LED发彩色光,大大提高了产品的优越性,丰富产品的性能,提高用户的体验感。而且,本发明中的具有Micro-LED400的阵列20可以根据显示模组30和终端40的大小设置不同的规格,设置相应匹配数量的Micro-LED,从而巧妙地避免了现有技术实现Micro-LED发彩色光需要批量转运的工序,进而大大提高产品的良率,保证产品的性能。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
