显示屏及电子装置 技术领域
本发明涉及电子设备技术领域，具体涉及一种电子装置及其发声控制方法。
背景技术
目前，由于全面屏电子装置具有高屏占比，可在不需要额外增加整机尺寸的情况下，显著的增加显示屏的显示区域的尺寸，因此，全面屏电子装置越来越成为了目前的主流。现在的全面屏电子装置在实现高屏占比时，需要面临的问题是如何同时维持前置摄像头和位于前屏的传感器的正常功能。
目前的全屏式电子装置通常有两种方式，第一种方式为通过刘海屏或水滴屏，在显示屏上预留一个非显示区域来安置前置摄像头和传感器等元件，第二种方式为通过将前置摄像头和传感器等元件设置于弹出式/旋转式结构中，在需要使用时，将弹出式/旋转式结构从装置本体弹出/转出，而可使得前置摄像头和传感器等元件可露出而实现相应的功能。然而，对于第一种方式，由于需要预留非显示区域，从而对进一步提高屏占比造成了一定的限制，对于第二种方式，弹出式/旋转式结构在弹出后容易遇到磕碰而导致损坏。
因此，有必要提出一种更好的全面屏解决方案。
发明内容

另一方面，提供一种电子装置，所述电子装置包括显示屏，所述显示屏包括金属阳极层、半透明阴极层以及像素单元层。所述金属阳极层包括多个间隔设置的金属阳极；所述半透明阴极层包括多个半透明阴极；所述像素单元层设置于所述金属阳极层和半透明阴极层之间，所述像素电极层包括多个间隔设置的像素单元，每一像素单元位于一对应的金属阳极以及对应的半透明阴极之间；其中，在显示屏的预设区域中，所述半透明阴极层还包括设置于多个半透明阴极之间或之上的遮光部，以及被所述遮光部包围的透光区域。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，为本申请一实施例中的显示屏100的部分位置的横截面示意图。所述显示屏100包括金属阳极层1、半透明阴极层2以及像素单元层3。所述金属阳极层1包括多个间隔设置的金属阳极11。所述半透明阴极层2包括多个半透明阴极21。所述像素单元层3设置于所述金属阳极层1和半透明阴极层2之间，所述像素电极层3包括多个间隔设置的像素单元31，每一像素单元31位于一对应的金属阳极11以及对应的半透明阴极21之间。其中，在显示屏100的预设区域中，所述半透明阴极层2还包括设置于多个半透明阴极21之间或之上的遮光部22，以及被所述遮光部22包围的透光区域23。
从而，本申请中，在显示屏100的预设区域中，通过在半透明阴极层2设置透光区域23，而使得光线可通过显示屏100，当显示屏100应用于电子装置时，而可供电子装置中的位于显示屏100内侧的有感光等需求的元器件可正常工作，而无需预留非显示区域进行开孔，极大地提高了显示屏的屏占比。
其中，所述遮光部22用于对像素单位31周围的走线进行遮蔽，用于减少走线产生的衍射，并通过配合所述透光区域23，可保证通光量。
本申请中，所述遮光部22设置于半透明阴极21之上指的是：所述遮光部22承载或附设于所述半透明阴极21上，并不是或并非仅限于方位位置位于半透明阴极21的上方。
其中，所述显示屏100用于显示输出，例如，显示相应的显示内容以供用 户观看，所述半透明阴极层2靠近显示屏100的供用户观看的观看面。
其中，所述透光区域23为镂空区域或者由全透明材料形成的区域。
即，在一些实施例中，所述透光区域23为完全贯穿所述半透明阴极层2的一个或多个通孔构成的镂空区域，或者，所述透光区域23可以为在贯穿所述半透明阴极层2的一个或多个通孔中进一步填充全透明材料形成的区域。其中，所述全透明材料可为全透明的玻璃、树脂等材料。
请一并参阅图2，为所述显示屏100的预设区域的俯视示意图。如图2所示，在所述预设区域中，相邻的半透明阴极21之间或之上均设置有遮光部22，相邻的半透明阴极21之间或之上设置的遮光部22共同包围有透光区域23，因此，所述半透明阴极层2在所述预设区域中包括多个透光区域23。
从而，在所述透光区域23和夹设在半透明阴极21以及金属阳极11之间的像素单元31为交错排列，从而，不影响预设区域的显示，且能够透过光线，而可供需感光等的元器件实现对应的功能。
其中，半透明阴极21、金属阳极11以及像素单元31为沿着与显示屏100平面垂直的方向上层叠在一起，从而，在图2所示的俯视视角下，半透明阴极21、金属阳极11以及像素单元31位于同一区域中。
其中，所述需感光的元器件可为亮度/光传感器、摄像头镜头模组等等。
其中，如图1所示，相邻的半透明阴极21之间或之上的遮光部22用于对所述半透明阴极21对应的像素单元31周围的金属走线L1进行遮蔽，所述遮光部22根据需要遮蔽的金属走线L1的排布位置进行延伸。
在一些实施例中，所述遮光部22延伸遮蔽对应的像素单元周围的金属走线L1区域后还进一步延伸形成特定形状的边界线，而包围形成具有特定形状的透光区域23，例如，所述透光区域23为圆形、椭圆形或矩形。即，在一些实施例中，金属走线区域在遮光部22上的投影区域位于遮光部22之内，所述遮光部22延伸遮蔽对应的像素单元周围的金属走线L1区域后还进一步延伸，而确保能够完整遮蔽金属走线。
在另一些实施例中，所述遮光部22延伸至正好遮蔽对应的像素单元周围的金属走线L1区域的位置，从而，所述透光区域23为以金属走线L1区域的边沿的作为边界线围绕形成的区域。即，在另一实施例中，金属走线L1区域 在遮光部22上的投影区域与遮光部22大致重合，所述遮光部22围绕的透光区域23的边界线与金属走线的边沿大致相同，而使得所述透光区域23为以金属走线L1区域的边沿的作为边界线围绕形成的区域。此时，透光区域23的面积可最大化，从而有效提升预设区域内的光线透过率。
其中，如图1和2所示，所述像素单元31可包括红色像素单元311、绿色像素单元312以及蓝色像素单元313。所述红色像素单元311、绿色像素单元312以及蓝色像素单元313构成一个像素点，所述显示屏100包括多个呈矩阵式排列的像素点。
如图1和图2所示，所述透光区域23设置于相邻的像素单元31之间，在相邻的红色像素单元311与绿色像素单元312之间、相邻的绿色像素单元312与蓝色像素单元313之间，以及相邻的蓝色像素单元313与红色像素单元311之间均设置有透光区域23。
如图2所示，所述透光区域23与像素单元31设置于同一行。
请参阅图3，为另一实施例中的显示屏100的预设区域的俯视示意图。在另一实施例中，所述透光区域23还可以设置于以相邻两行的相邻的四个像素单元31为顶点的矩形区域中。其中，在图3所示的实施例中，能够使得相邻的像素单元31的间距减小，而提高分辨率，且所述透光区域23设置于四个像素单元之间，可以尽可能设置得更大，而整体上并不会对透光效果造成更大影响。
请参阅图4，为再一实施例中的显示屏100的预设区域的俯视示意图。在再一施例中，相邻的像素单元31之间以及相邻两行的相邻的四个像素单元31为顶点的矩形区域中，均可以设置透光区域23。即，如图4所示，相邻的像素单元31之间设置有透光区域23，同时相邻两行的相邻的四个像素单元31为顶点的矩形区域，也可以设置透光区域23。
从而，通过在相邻的像素单元31之间以及相邻两行的相邻的四个像素单元31为顶点的矩形区域中，均设置透光区域23，有效地提升了透光效果。
请返回参考图1，在一些实施例中，每一半透明阴极21与每一像素单元31的尺寸相同，所述遮光部22包括设置于多个半透明阴极21之间而与多个半透明阴极21共面的不透明阴极221，所述透光区域23为被不透明阴极221 包围的镂空区域或者在镂空区域中填充全透明材料形成的区域。
即，在一些实施例中，如图1所示，所述遮光部22为设置于多个半透明阴极21之间的不透明阴极221，所述不透明阴极221包围所述透光区域23，所述不透明阴极221对金属走线L1进行遮蔽。
进一步的，在一些实施例中，可先在每个像素单元31上图形化形成半透明阴极21；然后，在半透明阴极21分布的同一层中，再图形化形成不透明阴极221，不透明阴极221与半透明阴极21相连接，而形成一整层完整的半透明阴极层2；然后再在不透明阴极221中的未对应金属走线L1的区域(例如，相邻的像素单元31之间的区域以及相邻两行的相邻的四个像素单元31为顶点的矩形区域)开设一个或多个贯穿通孔而形成为镂空区域的透光区域23，或者进一步在镂空区域中填充全透明材料而形成所述透光区域23，而剩余的包围透光区域23的不透明阴极221则用来作为遮光部22对金属走线L1进行遮蔽。
其中，半透明阴极21以及不透明阴极221均可通过蒸镀图形化方式形成。
请参阅图5，为另一实施例中的显示屏100的部分位置的横截面示意图。如图5所示，每一半透明阴极21的尺寸大于对应的像素单元31的尺寸，且每一像素单元31在对应的半透明阴极21上的投影位于所述半透明阴极21中。所述遮光部22层叠设置于半透明阴极21的边缘区域211的表面上，所述边缘区域211为像素单元31在半透明阴极21上的投影区域之外的区域，所述边缘区域211根据需要遮蔽的金属走线L1的排布位置进行延伸。如图5所示，所述透光区域23由层叠设置的遮光部22以及半透明阴极21共同包围形成。
即，在另一实施例中，遮光部22为层叠设置于半透明阴极21上的。
上述的每一像素单元31在对应的半透明阴极21上的投影位于所述半透明阴极21中可为：每一像素单元31在对应的半透明阴极21上的投影的边界各处与所述半透明阴极21均具有一定距离，从而，像素单元31对应的半透明阴极21上的投影完全位于对应的半透明阴极21内，且半透明阴极21的边缘区域211为环绕半透明阴极21的边沿的区域。
其中，所述遮光部22可设置于半透明阴极21的边缘区域的靠近所述像素单元31的表面，或者设置于半透明阴极21的边缘区域的远离所述像素单元 31的表面。
其中，可先在每个像素单元31上图形化形成尺寸大于所述像素单元31的半透明阴极21；然后，在半透明阴极21的边缘区域211的表面图形化形成遮光部22。
其中，半透明阴极21以及遮光部22均可通过蒸镀图形化方式形成。
例如，如图5所示，所述遮光部22为设置于半透明阴极21的边缘区域的远离/背向所述像素单元31的表面。
请参阅图6，为再一实施例中的显示屏100的部分位置的横截面示意图。在再一实施例中，所述遮光部22为设置于半透明阴极21的边缘区域的靠近/朝向所述像素单元31的表面。
请参阅图7，为其他实施例中的显示屏100的部分位置的横截面示意图。在其他实施例中，所述遮光部22可同时设置于半透明阴极21的边缘区域211的靠近所述像素单元31的表面以及半透明阴极21的边缘区域的远离所述像素单元31的表面，且设置于半透明阴极21的边缘区域211的靠近所述像素单元31的表面以及半透明阴极21的边缘区域211的远离所述像素单元31的表面的遮光部22可相互对称。
即，在其他实施例中，每一半透明阴极21的边缘区域211的靠近所述像素单元31的表面以及远离所述像素单元31的表面均设置有遮光部22，且两个表面的遮光部22对称设置。
显然，在一些实施例中，还可以部分半透明阴极21的边缘区域211的靠近所述像素单元31的表面设置遮光部22，部分半透明阴极21的边缘区域的远离所述像素单元31的表面设置遮光部22，另外部分的半透明阴极21的边缘区域的靠近所述像素单元31的表面以及远离所述像素单元31的表面均设置有遮光部22。
即，所述半透明阴极的边缘区域211的两个相对表面上均设置有遮光部。
其中，所述遮光部22为设置于半透明阴极21的边缘区域211的表面时，可为通过蒸镀方式形成于半透明阴极21的边缘区域211的表面上。
其中，如图5-7所示的，当所述遮光部22为设置于半透明阴极21的边缘区域211的表面时，所述遮光部为不透明材料或为半透明材料制成。
例如，所述遮光部22同样可为半透明阴极21，所述遮光部22层叠于半透明阴极21上后，使得所述半透明阴极21在边缘区域211进行了加厚，而通过加厚的半透明阴极21实现不透明效果，进而对下方的金属走线L1进行遮蔽。
又例如，所述遮光部22也可为不透明阴极，通过层叠在半透明阴极21上，实现对下方的金属走线L1的遮蔽。
其中，所述半透明阴极21可为半透明的氧化铟锡材料或者半透明的金属材料制成，所述半透明阴极21的透光率为百分之五十。所述不透明阴极可为不透明的金属等材料制成。
其中，本申请的显示屏可为OLED(organic light-emitting diode，有机发光二极管)显示屏，如图1、5-7等图所示，每个像素单元31夹设于一半透明阴极21和一金属阳极11之间，所有的半透明阴极21可作为公共电极而与接地点连接而处于0V电压。每一金属阳极11作为像素电极，而与驱动电路(图中未示)连接，驱动电路根据待显示内容的数据控制施加相应的驱动电压至对应的金属阳极11，而使得金属阳极11驱动像素单元31相应发光而呈现相应的颜色，进一步使得显示屏100显示对应的内容。
其中，金属阳极层1中的金属阳极11可为不透明金属材料。
如图1、5-7等图所示，相邻的金属阳极11之间具有空隙，相邻的像素单元31之间也具有空隙，每一透光区域23与对应的相邻的金属阳极11之间的空隙以及相邻的像素单元31之间的空隙连通。且像素单元31之间的空隙沿着从半透明阴极层2到金属阳极层1方向上的投影与金属阳极11之间的空隙重合或者部分重合。透光区域23在沿着从半透明阴极层2到金属阳极层1方向上的投影落在所述金属阳极11之间的空隙以及像素单元31之间的空隙中。
从而，所述透光区域23、像素单元31之间的空隙以及所述金属阳极11之间的空隙形成了光路通道。当在显示屏100的内侧，即显示屏100的非观看面设置需要感光的元器件时，光线可依次通过透光区域23、像素单元31之间的空隙以及所述金属阳极11之间的空隙进入所述元器件，而实现所述元器件的相应功能。
其中，图1、5-7中仅示意出了两行共六个像素单元31及六个对应的金属阳极11及半透明阴极21，显然，预设区域中可为包括多个像素单元31及多 个对应的金属阳极11及半透明阴极21的区域。且如图1、5-7所示，位于最两侧的半透明阴极21，没有相邻的半透明阴极21的一端则未设置有遮挡部22，也无需设置遮挡部22。
请参阅图8，为显示屏100的整体俯视示意图。如图8所示，显示屏100上具有预设区域Z1，所述显示屏100可大致为矩形形状，包括两个相对的长边和两个相对的短边。所述预设区域Z1可位于显示屏100的靠近一处短边的位置处。
其中，所述预设区域Z1的像素分辨率低于显示屏100的其他区域。从而，通过将预设区域Z1的像素分辨率设置地较低，从而，在该预设区域Z1中的像素单元31的数量将较少，从而，可以留出区域来设置透光区域23，而可供光线透过。
其中，所述预设区域Z1与显示屏100的其他区域的像素分辨率的差异位于人的肉眼较难分辨出来的差异范围之内。例如，显示屏100在预设区域Z1之外的区域的像素分辨率为1920*1080比例，在该预设区域Z1则采用的为1280*720比例的分辨率，能够留出较多区域来设置透光区域23，且人肉眼无法感觉到分辨率的差异，而不会影响用户的视觉效果。
其中，如图8所示，所述显示屏100上仅包括一个预设区域Z1，且靠近显示屏100的一个短边的位置设置，且所述预设区域Z1与显示屏100的各个边都间隔有一定距离。
请参阅图9，为另一实施例中的，显示屏100的整体俯视示意图，在另一实施例中，显示屏100可包括两个预设区域Z1，例如，如图9所示，两个预设区域Z1分别靠近两个相对的短边设置。每一个预设区域Z1中均具有前述的金属阳极层1、半透明阴极层2以及像素单元层3，以及透光区域23等结构。
通过在显示屏100的两个相对的短边均设置有预设区域Z1，当显示屏100应用于电子装置时，可以在电子装置对应两个预设区域Z1的位置都设置需感光的元器件，例如设置摄像组件的摄像头镜头，而可实现广角摄像。
其中，本申请中，透光区域23仅设置于预设区域Z1中，显示屏100的其他区域则不设置透光区域23，且其他区域可与正常的OLED显示屏的结构相同。
在一些实施例中，所述遮光部22可形成于显示屏100的所有区域，而对显示屏100的所有像素单元31周围的金属走线L1进行遮蔽。在其他实施例中，所述遮光部22也可仅设置于所述预设区域Z1中，在显示屏100的位于预设区域Z1之外的其他区域，则可以通过黑矩阵等方式对金属走线L1进行遮蔽，即，与正常的OLED显示屏的结构相同。
其中，所述显示屏100还可以包括盖板，所述盖板盖设于所述半透明阴极层2上，即盖设于所述半透明阴极层2的远离像素单元层3的一侧，而对所述显示屏100进行保护。所述盖板可为全透明的玻璃盖板、树脂盖板等等。
请一并参阅图10及图11，图10为本申请一实施例中的电子装置200的结构框图。图11为电子装置200的示意出部分元器件的横截面示意图。所述电子装置200包括了如前任一实施例所述的显示屏100，所述电子装置200并还包括感光器件201。
其中，如图11所示，所述感光器件300设置于所述电子装置200内，且对应所述显示屏100的预设区域Z1设置。
具体的，如前所述，相邻的金属阳极11之间具有空隙，相邻的像素单元31之间也具有空隙，在预设区域Z1中的每一透光区域23与对应的金属阳极11之间的空隙以及像素单元31之间的空隙连通。且像素单元31之间的空隙沿着从半透明阴极层2到金属阳极层1方向上的投影与金属阳极11之间的空隙重合或者部分重合。透光区域23在沿着从半透明阴极层2到金属阳极层1方向上的投影落在所述金属阳极11之间的空隙以及像素单元31之间的空隙中。
从而，所述透光区域23、像素单元31之间的空隙以及所述金属阳极11之间的空隙形成了光路通道，光线可依次通过透光区域23、像素单元31之间的空隙以及所述金属阳极11之间的空隙而传输至所述感光器件201，使得所述感光器件300进行感光而产生相应的光感应信号，以实现相应的功能。
其中，感光器件201的感光面的大小可与预设区域Z1的大小大致相同，预设区域Z1的所有透光区域23传送过来的光线均可被感光器件201接收，
在一些实施例中，所述感光器件201包括光传感器、摄像头镜头模组中的至少一种。
其中，所述摄像头镜头模组可包括摄像头镜头和图像传感器。
如图10所示，所述电子装置200还包括处理器202，所述处理器202与感光器件201连接，用于根据感光器件201产生的光感应信号而执行对应的功能。
其中，当感光器件201为光传感器时，在接收到外部光线时，而产生相应的光感应信号，处理器202接收该光感应信号而确定外部环境的亮度，而可控制自动调节显示屏100的显示亮度。
当感光器件201为摄像头镜头模组时，感光器件201接收外部光线而产生相应的图像光感应信号，处理器202接收该图像光感应信号而进行成像处理。
在一些实施例中，当预设区域Z1为两个时，例如，如前所述，预设区域Z1分别设置于靠近显示屏100的两个相对的短边的位置，本申请的电子装置200为全面屏显示屏，因此，显示屏100的尺寸与电子装置200在显示屏100平面上的尺寸大致相同。两个预设区域Z1也相当于分别设置于电子装置200的两个相对的短边的位置。相应的，感光器件300的数量也为至少两个，且分别对应两个预设区域Z1设置。
当感光器件201为光传感器时，通过在电子装置200的两个相对的短边的位置分别进行感光而产生相应的光感应信号，从而，可以实现对周围环境亮度的更准确的侦测，所述处理器202可结合至少两个感光器件300产生的光感应信号确定最终的周围环境亮度，并根据最终确定的周围环境亮度控制调节显示屏100的显示亮度，而实现更精准的调节。
当感光器件201为摄像头镜头模组时，通过在电子装置200的两个相对的短边的位置分别进行采光而产生相应的图像光感应信号，可以实现广角摄像或者深度摄像。具体的，所述处理器202可结合至少两个感光器件300产生的图像光感应信号来获取广角图像或深度图像，而获取更多类型的图像，满足用户更多的需求。
其中，所述处理器202可为整合图像处理器等在内的处理器，且具体可为中央处理器、数字信号处理器、单片机等。
所述电子装置200可为手机、平板电脑、数码相机等具有显示屏和感光器件的电子装置。
从而，本申请中，在显示屏100的预设区域中，通过在半透明阴极层2设置透光区域23，而使得光线可通过显示屏100，当显示屏100应用于电子装置200时，而可供电子装置200中的位于显示屏100内侧的有感光等需求的感光器件201可正常工作，而无需预留非显示区域进行开孔，极大地提高了显示屏100的屏占比。
