Abstract

本申请涉及一种终端及显示屏，其中终端包括显示区域；所述显示区域包括至少两个显示区；所述至少两个显示区包括第一显示区和第二显示区；所述第一显示区的像素密度小于所述第二显示区的像素密度，且所述第一显示区的像素密度小于或等于所述第一显示区在未被点亮状态下呈现透明状态时对应的最大像素密度。当终端采用上述显示屏时，可以将前置设备如前置摄像头等设置在第一显示区的下方。当需要使用前置摄像头时，只需要控制第一显示区处于未被点亮状态即可。然而，在前置摄像头不工作时，由于前置设备上方区域也属于显示区域，显示屏的各显示区均可以正常显示，能够真正实现终端的全面屏显示。

Description

终端及显示屏 技术领域
本申请涉及显示技术领域，特别是涉及一种终端及显示屏。
背景技术
在显示领域中，全面屏显示技术已经逐渐成为主流，这种技术对于提高手机的屏占比(手机显示屏幕和手机前面板面积的相对比值)非常有帮助。在实现全面屏显示过程中，前置摄像头等前置设备的设置是最困难的。传统的终端需要在终端顶部设置非显示区，前置摄像头则处于该非显示区内，显然这种方案并不能实现终端的全面屏显示。
申请内容
基于此，有必要提供一种能够实现全面屏显示的终端及显示屏。
根据本申请的一个方面，提供了一种显示屏，包括显示区域；所述显示区域包括至少两个显示区；所述至少两个显示区包括第一显示区和第二显示区；所述第一显示区的像素密度小于所述第二显示区的像素密度。
在其中一个实施例中，根据权利要求1所述的显示屏，其中，所述第一显示区的像素密度小于或等于所述第一显示区在未被点亮状态下呈现透明状态时对应的最大像素密度。
在其中一个实施例中，所述第一显示区的像素密度小于或等于150PPI。
在其中一个实施例中，所述第二显示区的像素密度与所述第一显示区的像素密度之间的差值至少为300PPI。
在其中一个实施例中，所述显示屏包括相对设置的第一端和第二端；所述第一显示区设置于所述显示屏的第一端；所述第二显示区设置于所述显示屏的第二端。
在其中一个实施例中，所述第一显示区与所述第二显示区沿所述显示屏的长度方向进行设置。
在其中一个实施例中，所述第一显示区与所述第二显示区沿所述显示屏的宽度方向进行设置。
在其中一个实施例中，所述第一显示区被所述第二显示区包围。
在其中一个实施例中，所述第一显示区的面积小于所述第二显示区的面积。
在其中一个实施例中，所述第一显示区采用的像素电路中的晶体管的数量，小于所述第二显示区采用的像素电路中的晶体管的数量。
在其中一个实施例中，所述第一显示区的像素电路为2T1C像素电路，所述第二显示区的像素电路为7T1C像素电路。
在其中一个实施例中，所述第一显示区中的各像素和所述第二显示区中的各像素均包含三个子像素；所述第一显示区中的各像素所包含的各子像素并列排布；所述第二显示区中的各像素所包含的其中两个子像素并列排布于该像素所包含的另一子像素的一侧。
在其中一个实施例中，所述第一显示区多于一个。
根据本申请的另一方面，提供了一种终端，包括本体和设置于所述本体上的显示屏；所述本体用于实现所述终端的目标功能；
所述显示屏包括显示区域；所述显示区域包括至少两个显示区；所述至少两个显示区包括第一显示区和第二显示区；所述第一显示区的像素密度小于所述第二显示区的像素密度，且所述第一显示区的像素密度小于或等于所述第一显示区在未被点亮状态下呈现透明状态时对应的最大像素密度；
所述本体包括前置设备；所述前置设备设置于所述显示屏的第一显示区的下方。
所述终端进一步包括控制器，当监测到前置设备工作时，控制第一显示区处于未被点亮状态，当前置设备不工作时，控制器对第一显示区和第二显示区进行控制，从而使得第一显示区和第二显示区按需进行显示，实现全面屏显示。
在其中一个实施例中，所述前置设备包括前置摄像头、感光器和产品标识中的至少一种。
上述终端及显示屏，显示屏至少包括第一显示区和第二显示区，第一显示区的像素密度小于第二显示区的像素密度，且第一显示区的像素密度小于或等 于第一显示区在未被点亮状态下呈现透明状态时对应的最大像素密度，从而使得第一显示区在未被点亮状态下时呈现透明状态。因此，当终端采用上述显示屏时，可以将前置设备如前置摄像头等设置在第一显示区的下方。当需要使用前置摄像头时，只需要控制第一显示区不被点亮即可，而在前置摄像头不工作时，由于前置设备上方区域也属于显示区域，显示屏的各显示区均可以正常显示，真正实现终端的全面屏显示。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请各实施例中的显示屏，其可以适用于各终端中，以满足用于对终端全面屏显示的需求。终端可以为手机、平板、掌上电脑以及计算机等设备。
图1为一实施例中的显示屏的屏体结构示意图。如图1所示，在本实施例中，显示屏包括显示区域，该显示区域至少包括两个显示区，该至少两个显示区包括第一显示区110和第二显示区120。具体地，第一显示区110和第二显示区120形成的整个显示区域也即为显示屏的屏体区域，从而使得使用该显示屏的终端能够真正实现全面屏显示。
其中，第一显示区110的像素密度小于第二显示区120的像素密度，且第一显示区110的像素密度小于或等于第一显示区110在未被点亮状态下呈现透 明状态时对应的最大像素密度。也即，第一显示区110的像素密度应该使得第一显示区110在未被点亮时呈现透明状态。其中，第一显示区110呈现透明状态，是指第一显示区110处于未被点亮状态时，设置于该第一显示区110下方的其他设备(如前置摄像头等)能够被用户看见，且其工作不会受到第一显示区110的影响。
当终端采用上述显示屏时，可以将前置设备(如前置摄像头等)设置在第一显示区110的下方，当需要使用前置摄像头时，只需要控制第一显示区110处于未被点亮状态即可。然而，在前置摄像头不工作时，由于前置设备上方的区域也属于显示区域，显示屏的各显示区均可以正常显示，能够真正实现终端的全面屏显示。
在一个实施例中，显示屏包括相对设置的第一端和第二端。其中，第一显示区110设置在显示屏的第一端，第二显示区120设置在显示屏的第二端。
在一个实施例中，第一显示区110和第二显示区120沿终端的长度方向设置。第一显示区110的面积小于第二显示区120的面积。其中，第一显示区110的大小可以根据需要放置在该第一显示区的下方的前置设备(如前置摄像头)的大小来确定。一个具体示例中，可以将第一显示区110的宽度设置为6mm，也即第一显示区110中远离第二显示区120的边框，与第二显示区120中靠近第一显示区110的边框之间的距离为6mm。
前置设备是指需要安装在终端的显示屏所在侧的设备，也即传统的终端上与显示屏位于同一侧的设备。具体地，前置设备可以为前置摄像头，也可以为感光器件或者按照实际需求进行显示的产品标识等。
在一个实施例中，第一显示区110和第二显示区120也可以沿终端的宽度方向设置。在一个实施例中，第一显示区110还可以被第二显示区120包围。
此外，第一显示区110在显示屏上的位置，可以根据终端中的前置设备的位置来确定。具体地，当多个前置设备集中设置在一个区域内时，第一显示区110可以仅为一个；当多个前置设备分散设置在多个区域时，如图2所示，可相应设置多个第一显示区110，使得每一个第一显示区110均对应一个或者多个前置设备。
在一个实施例中，第一显示区110的像素密度小于或等于150PPI，从而使得第一显示区110的透光率在60％以上，以此保证前置设备(如前置摄像头)的正常工作。
在一个实施例中，第二显示区120的像素密度大于第一显示区110的像素密度至少300PPI，即第二显示区120的像素密度与第一显示区110的像素密度之间的差值至少为300PPI，从而使得第二显示区120在未被点亮状态下，呈现非透明状态。
在一个实施例中，第一显示区110采用的像素电路中的晶体管的数量，小于第二显示区120采用的像素电路中的晶体管的数量。由于具有较少晶体管的像素电路所占用的电路遮光面积较小，因而可以进一步提高第一显示区110的透光率。
在一个实施例中，第一显示区110的像素电路为2T1C像素电路，其中T表示晶体管，C表示电容，各字母前面的数字则表示对应的个数，由此，如图3所示，第一显示区110的像素电路包括2个晶体管和1个电容。此外，下文出现的电路结构中亦表示相同的含义。如图4所示。第二显示区120的像素电路为7T1C像素电路。本申请文件中描述的7T1C像素电路和2T1C像素电路，对本领域技术人员而言均是清楚的，故本申请文件中不再对各像素电路的具体电路结构作详细描述。
在一个实施例中，第一显示区中的各像素和第二显示区中的各像素均包含三个子像素，具体地，各像素均包括红色子像素R、绿色子像素G和蓝色子像素B。并且，如图5所示，第一显示区110中的每个像素所包含的各子像素并列排布，也即第一显示区110中的像素采用条状排布结构进行排布。此外，如图6所示，第二显示区120中的每个像素所包含的其中两个子像素并列排布于该像素所包含的另一子像素的一侧，也即第二显示区120中的像素所包含的各子像素呈“V”型排布，在一个具体示例中，可将红色子像素R和绿色子像素G并列排布在蓝色子像素B的一侧。在其他的实施例中，也可以将各子像素的位置进行互换，而并不限于图6中展示的排布情况。
需要说明的是，本申请各实施例提供的显示屏不局限于用于具备前置设备 的终端中，也可以用于其它不具备前置设备的终端中，即该显示屏可以适用于任意一种终端中。
本申请还提供一种终端，该终端包括本体以及设置在本体上的显示屏。其中，本体用于实现终端的目标或者预期功能。显示屏则可以采用前述任一实施例中的显示屏。本体包括控制器和前置设备。在一个实施例中，前置设备可以是前置摄像头。
以下以前置设备为前置摄像头为例，对终端的工作原理进行说明。前置摄像头设置在第一显示区110的下方。控制器用于对前置摄像头的工作状态进行监测，从而在监测到前置摄像头工作时，控制第一显示区110处于未被点亮状态。第一显示区110处于未被点亮状态时会呈现出透明状态，外部光线可以穿过第一显示区110进入前置摄像头，从而不会影响前置摄像头的正常工作。此外，显示屏的其他区域由控制器独立进行控制，不受前置摄像头工作状态的影响。也即，终端在前置摄像头不工作时，控制器对第一显示区110和第二显示区120进行控制，从而使得第一显示区110和第二显示区120按需进行显示，实现全面屏显示。在前置摄像头工作时，控制器控制第一显示区110不被点亮，也即该显示区域不显示，从而使得前置摄像头可见，不会影响前置摄像头的正常工作，而其他显示区域由控制器进行独立控制，其显示过程不会受到影响。上述终端，当终端处于休眠、待机或者关机状态下，也即显示屏均未被点亮时，前置摄像头处于可见状态。
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申请专利范围的限制。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。
