如图1和图2所示，在一实施例中，提供一种电子装置10，所述电子装置10为手机，所述电子装置10包括屏幕100，所述屏幕100可以为OLED显示屏。
目前手机全面屏需求全面爆发，全面屏成为未来的趋势。全面屏的屏幕可以被划分成VA区域(Visual Area，可视区域)、AA区域(Active Area，有效区域)和BM区域(Black Matrix)。其中，VA区域即屏幕面板上所有可见的部分，AA区域则是可以编程控制显示的部分，VA区域大于AA区域。而BM区域位于VA的最外围，也就是屏幕黑边部分。由于屏幕的结构原因，BM区域的宽度也就是黑边宽度还是较宽，OLED显示屏的BM区域目前最窄为1.6mm左右，是实现全面屏技术的障碍。本申请通过在屏幕的黑边区域的OCA胶层打孔，使黑边区域的OCA胶层具有导光膜或散光片的效果，使 其将屏幕上的光线或者中框边上内置OLED灯等光源传导点亮BM区域。其中原有BM区域的油墨改为半透材质，使得光线能够透过。在屏幕被点亮时，其BM区域也会被点亮，在视觉上减少黑边宽度或消除黑边，实现最大化的全面屏视觉效果。
如图2至图4所示，在一实施例中，所述屏幕100为方形结构，包括盖板110、触控显示元件120、OCA胶层130和油墨层140。所述盖板110与所述触控显示元件120叠合设置，所述盖板110的面积大于所述触控显示元件120的面积，使得盖板110四周的边缘凸出于触控显示元件120四周的边缘。所述触控显示元件120包括触控层和显示层，使得屏幕100具有触控功能和显示功能。所述油墨层140位于盖板110的下表面，所述油墨层140由盖板110的边缘向内延伸，形成环状结构，且所述油墨层140的至少部分结构位于所述触控显示元件120在盖板110上的投影内。可以理解为，所述油墨层140为方形的环状结构，位于盖板110的下表面的边缘，且油墨层140的内环位于盖板110和触控显示元件120之间，使得油墨层140的部分结构与触控显示元件120的边缘重叠。所述盖板110的下表面可以理解为盖板110的朝向触控显示元件120的一侧的表面。油墨层140所围设的触控显示元件120的部分为屏幕100的有效区域，如图3所示，油墨层140所围设的结构即为屏幕100的AA区域。
如图4所示，在一实施例中，所述OCA胶层130粘接于所述盖板110和所述触控显示元件120之间。所述OCA胶层130的面积小于或等于盖板110的面积，且所述OCA胶层130的面积大于所述触控显示元件120的面积，所述OCA胶层130的边缘凸出于油墨层140的边缘。所述OCA胶层130的端部与油墨层140叠合，所述OCA胶层130的厚度大于油墨层140的厚度。
如图4所示，在一实施例中，所述OCA胶层130的与油墨层140贴合的端部上开设孔131，所述油墨层140可以透过光线，使得屏幕100工作时BM区域可以被点亮。所述OCA胶层130的与油墨层140贴合的端部上开设孔131，屏幕100内的光线可以透过孔131，使OCA胶层的端部具有导光膜或 散光片的效果。所述油墨层140由黑色的透明油墨制成，使得油墨层140具有一定的透光率，可以使屏幕100发出的至少部分光线穿过，表现为BM区域被点亮。
所述透明油墨的最大特点在于其油墨是遮盖力低，有良好的透明度，主要采用着色剂或大部分采用燃料制成的油墨。透明油墨的透明度由染料(颜料)和连结料(包含助剂)两部分决定，而且前者起主要作用，后者的影响很小。透明度的大小可以用透射系数表示。设进入油墨的光线强度为I0，透过油墨的光线强度为I，当油墨的厚度为一厘米时，则I/I0的比值Q称为矿物的透射系数。可以看出，吸收愈强愈不透明，即透射系数越小。油墨层140的透光率由其所采用的透明油墨的透明度确定，本申请所采用的透明油墨的透明度大于50％，使得油墨层140的透光率大于50％，便于屏幕100内的光线穿过油墨层140而点亮油墨层140。
如图4和图5所示，在一实施例中，所述中框160上设置光源161，光线通过孔131传导至油墨层140，并穿透油墨层140，点亮屏幕100的BM区域。具体的，在电子装置10中，所述屏幕100由中框160固定，所述中框160的朝向触控显示元件120的一侧设有光源161。所述光源161的光线穿过孔131点亮油墨层140，表现为屏幕100的BM区域被点亮，在视觉上减小屏幕100的黑边的宽度，实现最大化的全面屏视觉效果。在一实施例中，所述光源161为OLED灯。
一种屏幕100的制造方法，包括：
步骤a，在盖板110的下表面设置由边缘向内部延伸的环状油墨层140，所述油墨层140由透明油墨制成；
步骤b，将盖板110的下表面与触控显示元件120通过OCA胶层130粘接，所述OCA胶层130的端部与油墨层140叠合；
步骤c，在所述OCA胶层130的与油墨层140叠合的端部上开设孔131，使得所述屏幕100内的光线能够穿过孔131照亮油墨层140。
在一实施例中，步骤a包括，在盖板110的下表面上印刷透明油墨，形 成油墨层140。所述油墨层140为方形的环状结构，位于盖板110的下表面的边缘上，油墨层140的外环和内环之间具有一定的宽度，且外环和内环之间的宽度均匀。
在一实施例中，步骤b包括，将盖板110的下表面与触控显示元件120通过OCA胶层130粘接在一起。所述盖板110的面积大于所述触控显示元件120的面积，盖板110四周的边缘凸出于触控显示元件120四周的边缘。油墨层140一部分区域与触控显示元件120存在重叠。另一部分区域位于触控显示元件120的在盖板110上的投影之外。所述OCA胶层130的面积小于或等于盖板110的面积，且大于所述触控显示元件120的面积，使得OCA胶层的端部与油墨层140的叠合且凸出于触控显示元件120四周的边缘。
在一实施例中，步骤c包括，将OCA胶层130的与油墨层140叠合的端部上开设孔131，使得所述屏幕100内的光线能够穿过孔131照亮油墨层140。具体的，通过激光打孔的方式在OCA胶层130的与油墨层140叠合的端部上开设孔131，使得孔131均匀位于OCA胶层130的与油墨层140叠合的端部，且穿透OCA胶层130。触控显示元件120发出的光线可以穿过孔131传导至油墨层140上，且至少部分光线穿过油墨层140，使得油墨层140被点亮。
在一实施例中，电子装置10的屏幕100通过中框160固定，所述中框160的朝向触控显示元件120的一侧设有光源161。所述光源161的光线穿过孔131点亮油墨层140，表现为屏幕100的BM区域被点亮，在视觉上减小屏幕100的黑边的宽度，实现最大化的全面屏视觉效果。在一实施例中，所述光源161为OLED灯。
通过在OCA胶层130的与油墨层140叠合的端部上开设孔131，使其将触控显示元件120上的光线或者中框160上的光源161的光线传导点亮BM区域。其中原有BM区域的油墨层140改为透明油墨，使得光线能够透过。在屏幕100被点亮时，其BM区域也会被点亮，在视觉上减少黑边宽度或消除黑边，实现最大化的全面屏视觉效果。
在一实施例中，电子装置10可以包括多个可拆卸的屏幕100，实现多人 同时共享视频。所述屏幕100可以为柔性屏或者硬屏。电子装置10的USB接口可以置于电子装置10的中框160上，也可以置于屏幕100的侧边。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
