本申请中的术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
12:在第一安装孔内进行第一次喷胶以形成第一遮光胶部;
共同参阅2及图5,图5是图1的步骤12中显示模组一实施例的结构示意图,在该一实施例中,当第一安装孔110仅贯穿下偏光片102时,在面板组件101靠近下偏光片102的一侧及下偏光片102靠近第一安装孔110的端部形成的交界处进行第一次喷胶以形成第一遮光胶部120,从而防止在该交界处向第一安装孔110内发生漏光现象,在具体实施例的过程中,可通过旋转喷胶的方法,在上述的位置形成胶圈以作为第一遮光胶部120。
共同参阅图3及图6,图6是图1的步骤12中显示模组另一实施例的结构示意图,在另一实施例中,当第一安装孔110贯穿面板组件101及下偏光片102时,在面板组件101朝向第一安装孔110的端部进行第一次喷胶以形成第一遮光胶部120。
可选的,在该又一实施例中,还可以同时在面板组件101及上偏光 片103靠近第一安装孔110的端部进行第一次喷胶以形成第一遮光胶部120,又可以同时在面板组件101、下偏光片103及上偏光片102靠近第一安装孔110的端部进行第一次喷胶以形成第一遮光胶部120。
可选的,在该又一实施例中,当面板组件101靠近第一安装孔110的端部在朝向第一安装孔110的方向上凸出于上偏光片103靠近第一安装孔110的端部时,可在面板组件101靠近第一安装孔110的端部及面板组件101凸出于上偏光片103的部分上进行第一次喷胶以形成第一遮光胶部120,在遮光的同时,可提高第一遮光胶部120与面板组件101的粘接面积,防止第一遮光胶部120从面板组件120脱落。
可选的,第一遮光胶部120可选用热熔胶或紫外光固化胶,热熔胶是一种可塑性的粘合剂,在一定温度范围内其物理状态随温度改变而改变,而化学特性不变。相比于一般胶水而言,热熔胶的黏合强度更大,固化效果更佳;且更容易控制胶水的粗细,更能满足电子设备窄边框的设计要求;另外,热熔胶属于热塑性聚氨酯,使用热熔胶粘接的产品更易于拆卸或返修。例如,所述热熔胶可以为PUR热熔胶,即为湿气固化反应型聚氨酯热熔胶,主要成分是端异氰酸酯聚氨酯预聚体,PUR热熔胶的粘接性和韧性(弹性)可调节,并有着优异的粘接强度、耐温性、耐化学腐蚀性和耐老化性;紫外光固化胶是一种通过紫外光照射固化的一类胶粘剂,它可以作为粘接剂使用,例如,第一遮光胶部120选用黑色紫外光固化胶,该黑色紫外光固化胶可以满足挡光遮光的要求,且具有粘接力强,固化快,点胶薄等特点,通过采用黑色紫外光固化胶,在遮光的同时,还能够防止液体、水汽进入所述显示模组10的内部。
13:将背光模组与显示模组贴合,且使得第一安装孔与第二安装孔连通以形成一安装空间。
共同参阅图7及图8,图7是本申请提供的电子设备30一实施例的结构示意图,图8是本申请提供的电子设备30另一实施例的结构示意图,其中,将背光模组20中的光学组件202远离底壁2011的一侧与显示模组10中的下偏光片102贴合,以使得第一安装孔110与第二安装孔210形成安装空间310。
14:在第二安装孔内进行第二次喷胶,以形成连接第一遮光胶部及背光模组的第二遮光胶部。
具体的,在第一遮光胶部120及周侧壁2012上进行第二次喷胶,以形成连接第一遮光胶部120及周侧壁2012的第二遮光胶部220,从而通过第一遮光胶部120及第二遮光胶部220共同在安装空间310内进行遮光,以防止出现背光模组20向安装空间310内漏光的现象,且两次喷胶相比于一次喷胶的方法,能够避免一次喷胶出现喷胶宽度不足而导致不能有效遮光的情况,且若只进行一次喷胶,为了能够达到更好的遮光效果,必然会增加喷胶区域,从而导致在喷胶过程中,容易出现溅射到其他区域的情况。
可选的,本实施例中的装配方法还可以包括:
15:在安装空间内安装功能性器件。
可选的,该功能性器件320可以为摄像头模组。
进一步参阅图7及图8,本申请还提供了一种电子设备30,该电子设备30通过上述实施例中的方法装配而成,具体可参阅上述实施例中的相关描述,在此不再赘述。
本申请实施例提供的电子设备的装配方法,通过在显示模组的第一安装孔内进行第一次喷胶以形成第一遮光胶部,将背光模组与显示模组贴合以形成安装空间后在第二安装孔内进行第二次喷胶,以形成连接第一遮光胶部及背光模组的第二遮光胶部,从而通过第一遮光胶部及第二遮光胶部共同在安装空间内进行遮光,以防止出现背光模组向安装空间内漏光的现象,且两次喷胶相比于一次喷胶的方法,能够避免一次喷胶出现喷胶宽度不足而导致不能有效遮光的情况。
以上所述仅为本申请的部分实施例,并非因此限制本申请的保护范围,凡是利用本申请说明书及附图内容所作的等效装置或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
