具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。 以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本发明各个实施例提供的内容显示方法，可以由具有显示屏的电子设备来实现。该电子设备可以是智能手机、智能电视、平板电脑、电子书阅读器、MP3播放器(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面4)播放器和膝上型便携计算机(相机、摄像机)等等。该显示屏可以采用LCD(Liquid Crystal Display，液晶显示器)、LED(Light Emitting Diode，发光二极管)或OLED(Organic Light-Emitting Diode，有机发光二极管)等通过像素进行显示的显示屏。
如图1所示，其示出了本发明各个实施例提供的内容显示方法所涉及的实施环境的示意图，该实施环境即为具有显示屏的电子设备的内部环境，该实施环境包括处理器120、传输总线140、显示屏160以及显示屏160对应的驱动IC180。
处理器120可以为CPU(Central Processing Unit，中央处理器)或GPU(Graphics Processing Unit，图形处理器)，用于在生成显示内容对应的显示数据，并通过传输总线140将显示数据传输至驱动IC180。
处理器120和驱动IC180分别与传输总线140电性相连，并通过传输总线140进行显示数据的传输。
驱动IC180用于通过传输总线140接收处理器120发送的显示数据，并根据该显示数据控制显示屏160中相应像素单位进行显示内容的更新，其中，驱动IC180与显示屏160之间电性相连。
为了简化描述，下文中仅以内容显示方法由终端执行来举例说明，但对此不构成限定。
图2是根据一示例性实施例示出的一种内容显示方法的流程图，如图2所示，该内容显示方法包括以下步骤：
在步骤201中，检测显示屏中的显示内容是否发生变化。
在步骤202中，若显示内容未发生变化，则控制显示屏交替更新每行显示单位中的第一部分显示单位和第二部分显示单位对应的显示数据，该显示单位是按行划分的m行像素组合；或者，控制显示屏交替更新每列显示单位中的第三部分显示单位和第四部分显示单位对应的显示数据，该显示单位是按列划分的n列像素组合，m和n为正整数。
综上所述，本公开提供的内容显示方法，通过检测显示屏中的显示内容是否发生变化；在显示内容未发生变化时，控制显示屏交替更新每行显示单位中的第一部分显示单位和第二部分显示单位对应的显示数据；或者，控制显示屏交替更新每列显示单位中的第三部分显示单位和第四部分显示单位对应的显示数据，可以在保持原有刷新频率的同时，减少显示屏每次更新的像素数量，解决了降低显示屏的刷新频率导致显示屏产生闪屏现象的问题；达到了在保持显示屏原有刷新频率的同时，避免了显示屏的闪屏现象，降低显示屏功耗的效果。
图3A是根据一示例性实施例示出的一种内容显示方法的流程图，如图3A所示，该内容显示方法包括以下步骤：
在步骤301中，检测显示屏中的显示内容是否符合预定条件。
终端中的显示屏在显示内容时，需要由处理器按照预定频率向显示屏对应的驱动IC发送生成的显示数据，由驱动IC根据该显示数据控制显示屏对显示内容进行显示，其中，该处理器可以为CPU或GPU，该预定频率通常为60Hz。但是在某些特定的情况下，显示屏的显示内容可能在短时间内保持不变，对于配置有RAM(Random-Access Memory，随机存储存储器)的显示屏来说，当显示内容不变时，驱动IC可以从RAM中读取历史显示数据，从而避免了处理器在显示内容不变时生成相同显示数据所造成的资源浪费；但是对于未配置RAM的显示屏来说，即使在显示内容不变时，处理器仍旧需要不断生成相同的显示数据，造成处理器计算资源的浪费。
为了避免生成相同显示数据造成的处理器处理资源的浪费，终端可以实时检测显示内容是否符合预定条件，当检测到显示内容符合预定条件时，执行步骤302。其中，该预定条件包括显示内容属于预设应用或显示内容对显示帧数的要求小于预设帧数阈值中的至少一种。
该预设应用可以为电子书、图片浏览器一类的应用，此类应用对应的显示内容通常为静止画面，且在一段时间内保持不变。
另外，该预设帧数阈值可以为显示屏默认的刷新频率，即当显示内容为动态画面且帧数小于显示屏刷新频率时，该显示内容也符合预定条件，比如，当显示内容为视频，且视频的显示帧数为24帧/秒，显示屏的刷新频率为60Hz(即60帧/秒)时，该显示内容即符合预定条件。
在步骤302中，当检测到显示内容符合预定条件时，检测显示屏中的显示内容是否发生变化。
当检测到显示内容符合预定条件时，终端即检测待显示内容是否发生变化，当显示内容发生变化时，生成该显示内容对应的完整的显示数据；当显示内容未发生变化时，执行步骤303。
作为一种可能的实施方式，当显示内容属于预设应用，且终端接收到用户触发的显示内容变更信号时，终端即确定显示内容发生变化，该显示内容变更信号可以是用户触摸显示屏触发的信号。
作为另一种可能的实施方式，当显示内容对显示帧数的要求小于预设帧数阈值时，终端根据显示内容对显示帧数的要求以及显示屏的刷新频率，确定该显示内容的变化周期，并根据该变化周期检测显示内容是否发生变化。比如，当前显示内容对显示帧数的要求为15帧/秒，显示屏的刷新频率为60Hz(即60帧/秒)时，该显示内容的变化周期为4帧，即显示屏每刷新4帧变化一次显示内容。
在步骤303中，若显示内容未发生变化，则控制显示屏交替更新每行显示单位中的第一部分显示单位和第二部分显示单位对应的显示数据，该显示单位是按行划分的m行像素组合；或者，控制显示屏交替更新每列显示单位中的第三部分显示单位和第四部分显示单位对应的显示数据，该显示单位是按列划分的n列像素组合，m和n为正整数。
当检测到显示内容未发生变化时，终端控制显示屏交替更新每行显示单位中的第一部分显示单位和第二部分显示单位对应的显示数据。由于显示屏具有一定的图像保持能力(比如LCD中的液晶)，当更新第一部分显示单位对应的显示数据时，第二部分显示单位的显示内容不会消失，只是轻微减淡，对显示内容整体的显示效果影响极小，不会影响用户体验。同理，更新第三部分显示 单位和第四部分显示单位对应的显示数据时，对显示内容整体的显示效果影响也极小。
在第一种可能的实施方式中，当显示单位是按行划分的m行像素组合时，第一部分显示单位包含i个第一单元，第二部分显示单位包含j个第二单元，第一单元和第二单元相间，i和j为正整数，其中，该第一单元包含连续的p个像素，该第二单元包含连续的q个像素，p和q为正整数。
当显示单位是m行像素组合时，可以将一行显示单位的显示数据的更新分为a次，交替更新1/a个像素对应的显示数据。例如，当a为2时，分两次更新显示单位对应的显示数据，即，第一次更新第一部分显示单位对应的显示数据，第二次更新第二部分显示单位对应的显示数据，第三次更新第一部分显示单位对应的显示数据，第四次更新第二部分显示单位对应的显示数据，依次类推。当a为3时，分三次更新显示单位对应的显示数据，即，第一次更新第一部分显示单位对应的显示数据，第二次更新第二部分显示单位对应的显示数据，第三次更新第三部分显示单位对应的显示数据，依次类推。
需要说明的是，在保持原有的刷新频率不变的前提下，a的数值越大，显示频出现的闪频现象越严重。例如，原有的刷新频率为60Hz，当a为2时，每部分显示数据的刷新频率均为30Hz；当a为3时，每部分显示数据的刷新频率均为20Hz。其中，刷新频率越低，闪频现象越严重。
为了避免闪频现象，在一种可能的场景中，保持原有的刷新频率不变且将a的数值设置得较小，例如将a设置为2，此时每部分的显示数据的刷新频率为30Hz；在另一种可能的场景中，提高原有的刷新频率且将a的数值设置得较大，例如，将原有的刷新频率由60Hz提高为90Hz且将a设置为3，此时每部分的显示数据的刷新频率也为30Hz。
在将一行显示单位划分成第一部分显示单位和第二部分显示单位时，可以从一行显示单位中选取任意数量的像素作为第一部分显示单位，将剩余的像素作为第二部分显示单位，第一部分显示单位包括的像素数量与第二部分显示单位包括的像素数量可以相同，也可以不同。例如，当一行显示单位为一行像素组合且一行像素组合包括1920个像素时，将其中的960个像素作为第一部分显示单位，将剩余的960个像素作为第二部分显示单元。
在选取第一部分显示单位时，可以选取连续的多个像素。例如，将一行1920 个像素中的前960个像素组成第一部分显示单位，将后960个像素组成第二部分显示单位；或者，将一行1920个像素中的中间960个像素组成第一部分显示单位，将剩余的960个像素组成第二部分显示单位。或者，
在选取第一部分显示单位时，也可以选取不连续的多个像素。例如，第一部分显示单位包含i个第一单元，第二部分显示单位包含j个第二单元，且第一单元和第二单元相间，其中，该第一单元包含连续的p个像素，该第二单元包含连续的q个像素，请参考图3B和图3C，其中p和q均为b*b的像素阵列，阴影部分为第一部分显示单位，空白部分为第二部分显示单位。当然，p和q也可以不同，本实施例不作限定。
当p和q均为2时，请参考图3D和3E；当p和q均为1时，请参考图3F和图3G，其中阴影部分为第一部分显示单位，空白部分为第二部分显示单位。
本实施例中，相邻两行显示单位中，第一行显示单位中的所有第一单元和第二行显示单位中的所有第一单元在列方向上相互错开；且相邻两行显示单位中，第一行显示单位中的所有第二单元和第二行显示单位中的所有第二单元在列方向上相互错开。上述附图3B-3G中，相邻两行的阴影部分在列方向上相互错开。
需要补充说明的是，当显示单位是1行像素组合时，p个像素在该行中连续；当显示单位是2行或多行像素组合时，连续的p个像素为一个b*b的像素阵列，该像素矩阵中每行的b个像素是连续的，每列的b个像素不连续。即，连续的p个像素包括第1行的1-b个像素，第3行的1-b个像素、第5行的1-b个像素…依次类推，请参考图3B和3C。
当检测到显示内容未发生变化时，终端可以控制显示屏在奇数次更新时，仅更新各个第一单元对应的显示数据；在偶数次更新时，仅更新各个第二单元对应的显示数据。即，在奇数次更新时，更新图3B、3D和3F中的阴影部分；在偶数次更新时，更新图3C、3E和3G中的阴影部分。
在第二种可能的实施方式中，当显示单位是按列划分的n列像素组合时，第三部分显示单位包含k个第三单元，第四部分显示单位包含l个第四单元，第三单元和第四单元相间，k和l为正整数，其中，该第三单元包含连续的r个像素，该第四单元包含连续的s个像素，r和s为正整数。
本实施例中，相邻两列显示单位中，第一列显示单位中的所有第三单元和 第二列显示单位中的所有第三单元在行方向上相互错开；且相邻两列显示单位中，第一列显示单位中的所有第四单元和第二列显示单位中的所有第四单元在行方向上相互错开。
其中，第二种实施方式与第一种实施方式类似，详见第一种实施方式中的描述。
另外，请参考图3H和图3I，其中，r和s均为c*c的像素阵列，阴影部分为第一部分显示单位，空白部分为第二部分显示单位。当然，r和s也可以不同，本实施例不作限定。
当r和s均为2时，请参考图3J和3K；当r和s均为1时，与第一种实施方式中当p和q均为1时的情况相同，请参考图3F和图3G，其中阴影部分为第一部分显示单位，空白部分为第二部分显示单位。
当检测到显示内容未发生变化时，终端可以控制显示屏在奇数次更新时，仅更新各个第三单元对应的显示数据；在偶数次更新时，仅更新各个第四单元对应的显示数据。即，在奇数次更新时，更新图3H、3J和3F中的阴影部分；在偶数次更新时，更新图3I、3K和3G中的阴影部分。
显而易见的，采用上述方法控制显示屏显示内容，当显示内容保持不变时，显示屏每次刷新时不再需要更新完整的显示数据，每次刷新时只需要更新部分显示数据，比如，当按照显示单元的第一显示部分和第二显示部分交替更新，或者当按照显示单元的第三显示部分和第四显示部分交替更新时，每次刷新时更新的显示数据为原先的1/2，能够显著降低显示屏的功耗。
终端在控制显示屏更新显示内容时，包括如下三种可能的实施方式。
在第一种可能的实施方式，如图3L所示，上述步骤303可以包括如下步骤。
在步骤303A中，当检测到显示内容未发生变化时，通过处理器生成显示内容中所有显示单位对应的显示数据。
终端中处理器检测到显示内容未发生变化时，即根据显示屏的分辨率，通过处理器生成显示内容中所有显示单位对应的显示数据，其中，该处理器可以为CPU或GPU。比如，当显示屏的分辨率为1080*1920时，处理器生成的显示内容对应显示数据的数据量即为1080*1920＝2073600像素。
在步骤303B中，当显示单位是m行像素组合时，通过处理器控制传输总 线，向显示屏的驱动IC交替传输第一部分显示单位和第二部分显示单位对应的显示数据；或者，当显示单位是n列像素组合时，通过处理器控制传输总线，向显示屏的驱动IC交替传输第三部分显示单位和第四部分显示单位对应的显示数据，驱动IC用于根据接收到的显示数据控制显示屏进行更新。
为了减少显示内容不变时显示屏更新的显示数据的数据量，处理器在检测到显示内容未发生变化时，若显示单位是m行像素组合，则控制传输总线向显示屏的驱动IC交替传输第一部分显示单位和第二部分显示单位对应的显示数据，或者，若显示单位是n列像素组合，则控制传输总线向显示屏的驱动IC交替传输第三部分显示单位和第四部分显示单位对应的显示数据。
驱动IC通过传输总线接收到该显示数据后，根据该显示数据控制显示屏中相应的像素进行更新。由于传输总线交替传输第一部分显示单位和第二部分显示单位对应的显示数据，因此，显示屏每次更新显示内容时，仅更新第一部分显示单位和第二部分显示单位对应的显示数据。或者，传输总线交替传输第三部分显示单位和第四部分显示单位对应的显示数据，因此，显示屏每次更新显示内容时，仅更新第三部分显示单位和第四部分显示单位对应的显示数据。交替传输部分显示单位对应的显示数据，相较于传统的更新方式，更新的数据量显著降低，且不会影响用户观感。另外，由于传输总线上传输的数据量显著降低，数据传输造成的电磁干扰也相应减弱，保证了终端中其它组件的正常运行。
需要说明的是，当检测到显示内容发生变化时，处理器即通过传输总线将完整的显示数据发送至驱动IC，由驱动IC控制显示屏更新显示内容中所有显示单位对应的显示数据。
本实施例中，当显示内容未发生变化时，若显示单位是m行像素组合，通过处理器控制传输总线，向显示屏的驱动IC交替传输第一部分显示单位和第二部分显示单位对应的显示数据；或者，若显示单位是n列像素组合，通过处理器控制传输总线，向显示屏的驱动IC交替传输第三部分显示单位和第四部分显示单位对应的显示数据，驱动IC用于根据接收到的显示数据控制显示屏进行更新，降低了传输总线的功耗，且能够减小显示数据在传输总线上传输时产生的电磁干扰。
在第二种可能的实施方式，如图3M所示，上述步骤303可以包括如下步骤。
在步骤303C中，当检测到显示内容未发生变化时，通过处理器生成显示内容中所有显示单位对应的显示数据。
本步骤的实现方式与上述步骤303A相似，在此不再赘述。
在步骤303D中，通过处理器向显示屏的驱动IC传输该显示数据，该显示数据通过传输总线传输。
与上述步骤303B不同的是，处理器通过传输总线，将完整的显示数据传输至驱动IC。
在步骤303E中，当显示单位是m行像素组合时，通过处理器向驱动IC发送第一交替更新指令，驱动IC用于根据第一交替更新指令控制显示屏对第一部分显示单位和第二部分显示单位对应的显示数据进行交替更新；或者，当显示单位是n列像素组合时，通过处理器向驱动IC发送第二交替更新指令，驱动IC用于根据第二交替更新指令控制显示屏对第三部分显示单位和第四部分显示单位对应的显示数据进行交替更新。
处理器向传输总线传输完整的显示数据的同时，向驱动IC发送交替更新指令，当所述显示单位是m行像素组合时，指示驱动IC控制显示屏对显示数据中第一部分显示单位和第二部分显示单位的显示数据进行交替更新，或者，当所述显示单位是n列像素组合时，指示驱动IC控制显示屏对显示数据中第三部分显示单位和第四部分显示单位的显示数据进行交替更新，从而达到显示屏交替更新显示数据，降低显示屏在显示内容不变时的功耗的效果。
需要说明的是，当显示内容发生变化时，处理器仅通过传输总线，将完整的显示数据传输至驱动IC，而不再发送该交替更新指令，相应的，驱动IC控制显示屏对显示数据中所有显示单位的显示数据进行更新。
本实施例中，当显示内容未发生变化时，处理器向显示屏的驱动IC发送所有显示单位对应的显示数据的同时，还向驱动IC发送交替更新指令，指示驱动IC控制显示屏对显示数据中第一部分显示单位和第二部分显示单位的显示数据进行交替更新，或者指示驱动IC控制显示屏对显示数据中第三部分显示单位和第四部分显示单位的显示数据进行交替更新，从而减少显示内容不变时显示屏的显示数据更新量，降低显示屏的功耗。
在第三种可能的实施方式，如图3N所示，上述步骤303可以包括如下步骤。
在步骤303F中，当检测到显示内容未发生变化时，若显示单位是m行像素组合，则通过处理器交替生成显示内容中第一部分显示单位和第二部分显示单位对应的显示数据；或者，当检测到显示内容未发生变化时，若显示单位是n列像素组合，则通过处理器交替生成显示内容中第三部分显示单位和第四部分显示单位对应的显示数据。
与上述步骤303A和步骤303C不同的是，在检测到显示内容未发生变化时，处理器在显示数据生成阶段，交替生成第一部分显示单位和第二部分显示单位对应的显示数据，或者，交替生成显示内容中第三部分显示单位和第四部分显示单位对应的显示数据，相较于生成完整的显示数据，由于仅生成部分显示数据，处理器在生成显示数据时耗费的处理资源显著降低，从而降低了处理器的功耗。
在步骤303G中，通过处理器向显示屏的驱动IC传输生成的显示数据，驱动IC用于根据接收到的显示数据控制显示屏进行更新，该显示数据通过传输总线传输。
处理器交替生成第一部分显示单位和第二部分显示单位对应的显示数据，或者交替生成第三部分显示单位和第四部分显示单位对应的显示数据，通过传输总线将生成的显示数据传输至驱动IC，由驱动IC根据该显示数据控制显示屏进行相应的更新，不仅减少了显示内容不变时显示屏更新的数据量，还能够减少传输总线上传输的数据量，减小显示数据在传输总线上传输时产生的电磁干扰。
本实施例中，当显示内容未发生变化时，处理器交替生成显示内容中第一部分显示单位和第二部分显示单位对应的显示数据，或者，交替生成显示内容中第三部分显示单位和第四部分显示单位对应的显示数据，并通过传输总线发送至显示屏的驱动IC，由驱动IC根据该显示数据控制显示屏进行交替更新，不仅能够减少处理器生成的显示数据量，降低处理器的功耗，而且能够降低传输总线的功耗，减小显示数据在传输总线上传输时产生的电磁干扰。
在驱动IC通过上述三种方式得到显示数据后，可以控制显示屏进行显示数据的更新。在实现时，步骤303还可以包括：若显示单位是按行划分的m行像素组合，在奇数次更新时，通过驱动IC控制各个第一单元中的所有像素的开关 处于第一状态，且控制各个第二单元中的所有像素的开关处于第二状态；在偶数次更新时，通过驱动IC控制各个第一单元中的所有像素的开关处于第二状态，且控制各个第二单元中的所有像素的开关处于第一状态；若显示单位是按列划分的n列像素组合，在奇数次更新时，通过驱动IC控制各个第三单元中的所有像素的开关处于第一状态，且控制各个第四单元中的所有像素的开关处于第二状态；在偶数次更新时，通过驱动IC控制各个第三单元中的所有像素的开关处于第二状态，且控制各个第四单元中的所有像素的开关处于第一状态。
在电路实现时，可以将每个像素通过对应的使能线电性连接至驱动IC，且每个像素通过开关与数据线电性相连。其中，驱动IC可以通过使能线控制像素对应的开关的状态。其中，第一状态为闭合状态，第二状态为断开状态；或者，第一状态为断开状态，第二状态为闭合状态。
例如，当驱动IC通过使能线控制像素的开关处于闭合状态时，数据线上传输显示数据来更新该像素的显示数据；当驱动IC通过使能线控制像素的开关处于断开状态时，该像素的显示数据保持不变。
本实施例中，可以对每个像素设置一条数据线，也可以对多个像素设置一条数据线，本实施例不作限定。请参考图O，其中，以对一列像素组合设置一条数据线为例进行说明，假设第一单元和第二单元分别包含连续的2个像素，则在扫描第一行像素组合，即，更新第一行显示单位对应的显示数据时，控制通过使能线1控制开关1和2闭合，通过使能线2控制开关3和4断开，…，依次类推，通过使能线b/2控制开关b-1和b闭合；在扫描第二行像素组合时，通过使能线1控制开关1和2断开，通过使能线2控制开关3和4闭合，…，依次类推，通过使能线b/2控制开关b-1和b断开。
综上所述，本实施例提供的显示方法，通过检测显示内容是否发生变化，并在检测到显示内容未发生变化时控制显示屏交替更新显示内容中第一部分显示单位和第二部分显示单位对应的显示数据，或者，交替更新显示内容中第三部分显示单位和第四部分显示单位对应的显示数据；可以在保持原有刷新频率的同时，减少显示屏每次更新的像素数量，解决了降低显示屏的刷新频率导致显示屏产生闪屏现象的问题；达到了在保持显示屏原有刷新频率的同时，避免了显示屏的闪屏现象，降低显示屏功耗的效果。
此外，通过三种终端在控制显示屏更新内容时的实施方式，降低了传输总 线的功耗，达到了减小显示数据在传输总线上传输时产生的电磁干扰的效果。
