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。
图1是本公开各个实施例所涉及的终端的示意图，该终端包括：处理器120、显示芯片140和液晶面板160。该终端可以是智能手机、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。
处理器120可以是应用处理器或图形处理器。
显示芯片140可以包括DDIC(Display Driver Integrated Circuit，显示驱动集成电路)，显示芯片140能够实现对液晶面板160中显示内容的控制。
液晶面板160可以根据显示芯片140的控制进行显示，液晶面板160中包含m*n个液晶单元，液晶单元的排列方式示意性地如图2所示，一个液晶单元220表示一个像素点。通常，显示芯片140按照预定的刷新率对液晶面板160进行刷新，比如60Hz。
图3是根据本公开一示例性实施例示出的液晶显示方法的流程图，本实施例以该液晶显示方法应用于图1所示的终端中来举例说明。该方法可以包括如下步骤。
在步骤301中，获取液晶面板的第一显示内容中的各个像素点的灰阶数值；
第一显示内容是液晶面板160中的m*n个液晶单元上显示出的帧内容，第一显示内容包括m*n个像素点，每个像素点都具有各自的灰阶数值。可选地，灰阶数值的取值范围为0～255，灰阶数值为0时代表黑色，灰阶数值为255时代表白色。
可选的，第一显示内容可以是图像帧、视频帧、用户界面等。
可选的，本步骤由处理器或显示芯片来执行。
在步骤302中，响应于第一显示内容中的各个像素点的灰阶数值均小于预定数值，将液晶面板的刷新率由第一刷新率调整为第二刷新率，第二刷新率小于第一刷新率。
由于在灰阶数值很低时，像素点的显示颜色为黑色或近似黑色，此时降低刷新率也不会影响像素点的显示；所以，当第一显示内容的所有像素点的灰阶数值均小于预定数值时，也即第一显示内容的整体显示画面为黑色或近似黑色时，将液晶面板的刷新率由第一刷新率降低为第二刷新率。
可选地，第一刷新率是默认的刷新率，比如50Hz或60Hz或144Hz；第二刷新率是一个较低的刷新率，比如1Hz或2Hz或5Hz等。
综上所述，本公开实施例提供的液晶显示方法，通过获取液晶面板的第一显示内容中的各个像素点的灰阶数值，响应于当前显示内容中的各个像素点的灰阶数值均小于预定数值，将液晶面板的刷新率由第一刷新率调整为第二刷新率，第二刷新率小于第一刷新率；解决了相关技术中只靠降低背光光源的功耗来降低终端的功耗，能够降低的功耗有限的问题；达到了降低终端中液晶面板和显示芯片的功耗，从而更进一步地降低了终端的功耗的效果。
在上述实施例中，步骤301和步骤302可以由处理器来执行，对应于图4示出的实施例；步骤301和步骤302还可以由显示芯片来执行，对应于图5示出的实施例。
图4是根据本公开另一示例性实施例示出的液晶显示方法的流程图，本实施例以该液晶显示方法应用于图1所示的终端中来举例说明。该方法包括：
在步骤401中，获取液晶面板的第一显示内容中的各个像素点的灰阶数值；
可选地，液晶面板的第一显示内容包含m*n个像素点，每一个像素点包含红、绿、蓝三个子像素。m和n均为正整数。
以液晶面板是8位面板为例，则每一个子像素都存在256个亮度层次，即灰阶数值，每一个像素的颜色都是通过红、绿、蓝这三个子像素的灰阶数值的变化，再相加混合产生的，像素点的灰阶数值越小，像素点的颜色越接近黑色。
可选的，液晶面板还可以是10位面板或其他位数的面板，则此时像素点的每一个子像素包含更多的亮度层次。
处理器获取液晶面板的第一显示内容的每个像素点的灰阶数值，每个像素点的灰阶数值包括红、绿、蓝三个分量的灰阶数值。可选地，对于每个像素点，处理器选取这三个分量的灰阶数值中的最大值Q作为该像素点的灰阶数值。
处理器检测第一显示内容中的每个像素点的灰阶数值是否小于预定数值。该预定数值是黑色或近似黑色所对应的灰阶数值，比如：预定数值为0，或，预定数值为5等。预定数值可以是由终端预设的一个合理阈值，也可以是由用户自定义设定的阈值，本公开实施例对此不作限定。
响应于第一显示内容中的各个像素点的灰阶数值均小于预定数值，处理器将液晶面板的刷新率由第一刷新率调整为第二刷新率，第二刷新率小于第一刷新率，包括如下步骤402和步骤403：
在步骤402中，通过处理器响应于第一显示内容中的各个像素点的灰阶数值均小于预定数值，向显示芯片发送刷新率调整指令；
处理器将各个像素点的灰阶数值与预定数值进行比较，当处理器判断出每个像素点的灰阶数值都小于预定数值时，处理器向显示芯片发送刷新率调整指令。
在步骤403中，通过显示芯片响应于刷新率调整指令，将液晶面板的刷新率由第一刷新率调整为第二刷新率；
液晶面板的默认刷新率或初始刷新率为第一刷新率，即显示芯片将生成的显示内容发送至液晶面板的频率为第一刷新率，可选的，第一刷新率为60Hz。
显示芯片接收处理器发送的刷新调整指令，将液晶面板的刷新率调整为第二刷新率，即显示芯片按第二刷新率向液晶面板发送显示内容，第二刷新率低于第一刷新率，可选的，第二刷新率为1Hz。
可选的，当处理器判断出第一显示内容中存在至少一个像素点的灰阶数值不小于预定数值时，则液晶面板的刷新率保持第一刷新率不变。
需要说明的是，当显示芯片生成显示内容的帧率小于液晶面板的刷新率时，若当前帧和上一帧相比，显示内容相同时，保持当前刷新率不变。且不需要再重复获取此时显示内容中各个像素点的灰阶数值进行再次判断。
在步骤404中，获取液晶面板的第二显示内容中的各个像素点的灰阶数值，第二显示内 容是在第一显示内容之后显示的显示内容；
第二显示内容也是液晶面板160中的m*n个液晶单元上显示出的帧内容，第二显示内容包括m*n个像素点。
处理器获取第二显示内容的各个像素点的灰阶数值的方法与步骤401中获取第一显示内容的各个像素点的灰阶数值的方法相同，本实施例对此不再赘述。
响应于第二显示内容中存在至少一个像素点的灰阶数值不小于预定数值，处理器将液晶面板的刷新率由第二刷新率调整为第一刷新率，包括如下步骤405和步骤406：
在步骤405中，通过处理器响应于第二显示内容中存在至少一个像素点的灰阶数值不小于预定数值，向显示芯片发送刷新率调整指令；
处理器将第二显示内容中各个像素点的灰阶数值与预定数值进行比较，当处理器判断出存在至少一个像素点的灰阶数值不小于预定数值时，处理器向显示芯片发送刷新率调整指令。

综上所述，本公开实施例提供的方法，只有当显示内容的各个像素点的灰阶数值都小于预定数值时，即显示内容的亮度很低时，才降低液晶面板的刷新率，当显示内容的亮度较高时，仍然保持较高的刷新率，达到了在降低终端的功耗的基础上，仍然保证了显示内容正常显示的效果，基本对显示效果无影响的效果。
图5是根据本公开另一示例性实施例示出的液晶显示方法的流程图，本实施例以该液晶显示方法应用于图1所示的终端中来举例说明。该方法包括：
在步骤501中，获取液晶面板的第一显示内容中的各个像素点的灰阶数值；
可选地，液晶面板的第一显示内容包含m*n个像素点，每一个像素点包含红、绿、蓝三个子像素。m和n均为正整数。
以液晶面板是8位面板为例，则每一个子像素都存在256个亮度层次，即灰阶数值，每 一个像素的颜色都是通过红、绿、蓝这三个子像素的灰阶数值的变化，再相加混合产生的，像素点的灰阶数值越小，像素点的颜色越接近黑色。
可选的，液晶面板还可以是10位面板或其他位数的面板，则此时像素点的每一个子像素包含更多的亮度层次。
显示芯片获取液晶面板的第一显示内容的每个像素点的灰阶数值，每个像素点的灰阶数值包括红、绿、蓝三个分量的灰阶数值。可选地，对于每个像素点，显示芯片选取这三个分量的灰阶数值中的最大值G作为该像素点的灰阶数值。
显示芯片检测第一显示内容中的每个像素点的灰阶数值是否小于预定数值。该预定数值是黑色或近似黑色所对应的灰阶数值，比如：预定数值为0，或，预定数值为5等。预定数值可以是由终端预设的一个合理阈值，也可以是由用户自定义设定的阈值，本公开实施例对此不作限定。
在步骤502中，通过显示芯片响应于第一显示内容中的各个像素点的灰阶数值均小于预定数值，显示芯片将液晶面板的刷新率由第一刷新率调整为第二刷新率，第二刷新率小于第一刷新率；
液晶面板的默认刷新率或初始刷新率为第一刷新率，即显示芯片将生成的显示内容发送至液晶面板的频率为第一刷新率，可选的，第一刷新率为60Hz。
显示芯片将获取到的各个像素点的灰阶数值与预定数值进行比较，当显示芯片判断每个像素点的灰阶数值都小于预定数值时，显示芯片将液晶面板的刷新率调整为第二刷新率，即显示芯片按第二刷新率向液晶面板发送显示内容，第二刷新率低于第一刷新率，可选的，第二刷新率为1Hz。
可选的，当显示芯片判断出第一显示内容中存在至少一个像素点的灰阶数值不小于预定数值时，则液晶面板的刷新率保持第一刷新率不变。
需要说明的是，当显示芯片生成显示内容的帧率小于液晶面板的刷新率时，若当前帧和上一帧相比，显示内容相同时，则保持当前刷新率不变。且不需要再重复获取此时显示内容中各个像素点的灰阶数值进行再次判断。
在步骤503中，获取液晶面板的第二显示内容中的各个像素点的灰阶数值，第二显示内容是在第一显示内容之后显示的显示内容；
第二显示内容也是液晶面板160中的m*n个液晶单元上显示出的帧内容，第二显示内容包括m*n个像素点。
显示芯片获取第二显示内容的各个像素点的灰阶数值的方法与步骤501中获取第一显示内容的各个像素点的灰阶数值的方法相同，本实施例对此不再赘述。
在步骤504中，通过显示芯片响应于第二显示内容中存在至少一个像素点的灰阶数值不小于预定数值，显示芯片将液晶面板的刷新率由第二刷新率调整为第一刷新率。
显示芯片将第二显示内容中各个像素点的灰阶数值与预定数值进行比较，当显示芯片判断出存在至少一个像素点的灰阶数值不小于预定数值时，显示芯片将液晶面板的刷新率由第 二刷新率调整为第一刷新率。
可选的，当显示芯片判断出第二显示内容的各个像素点的灰阶数值都小于预定数值时，保持液晶面板的刷新率为第二刷新率。
需要说明的是，上述“第一”和“第二”没有特指的含义，可以指代液晶面板上显示的任意两帧相邻的帧内容。
综上所述，本公开实施例提供的液晶显示方法，通过获取液晶面板的第一显示内容中的各个像素点的灰阶数值，响应于当前显示内容中的各个像素点的灰阶数值均小于预定数值，将液晶面板的刷新率由第一刷新率调整为第二刷新率，第二刷新率小于第一刷新率；解决了相关技术中只靠降低背光光源的功耗来降低终端的功耗，所能降低的功耗有限的问题；达到了降低终端中液晶面板和显示芯片的功耗，从而更进一步地大大降低了终端的功耗的效果。
综上所述，本公开实施例提供的方法，只有当显示内容的各个像素点的灰阶数值都小于预定数值时，即显示内容的亮度很低时，才降低液晶面板的刷新率，当显示内容的亮度较高时，仍然保持较高的刷新率，达到了在降低终端的功耗的基础上，仍然保证了显示内容正常显示的效果，基本对显示效果无影响的效果。
综上所述，本公开实施例提供的方法，通过显示芯片获取像素点的灰阶数值并判断是否小于预定数值，从而调整刷新率，达到了降低处理器负荷的效果。
在基于图4和图5所示实施例的其他可选实施例中，步骤401和步骤501之前还包括其他步骤，如图6所示，还包括步骤601和步骤602：
在步骤601中，获取当前显示模式，当前显示模式包括静态显示模式和动态显示模式，静态显示模式是显示内容在预定时长内不发生改变的显示模式，动态显示模式是显示内容在预定时长内会发生改变的显示模式；
当前显示模式为当前显示内容所对应的显示模式，获取当前显示模式有多种实现方式：
在一种可能的实施方法中，处理器可以通过判断当前的显示场景来获取当前的显示模式，在静态显示场景中，显示内容的变化频率很小，处理器判断当前的显示模式为静态显示模式；在动态显示场景中，显示内容变化的很频繁，处理器判断当前的显示模式为动态显示模式。比如，视频是动态显示场景，则当处理器检测到当前在播放视频时，判断此时为动态显示模式；桌面锁屏是静态显示场景，则当处理器检测到当前处在锁屏环境时，判断此时为静态显示模式。
可选的，用户可以预先对不同的显示场景进行分类，设置它们分别属于静态显示场景还是动态显示场景。
在另一种可能的实施方式中，处理器获取显示缓冲区中的当前帧内容及其相邻的帧内容，检测当前帧内容与相邻帧内容的图像数据是否相同，当两帧图像数据相同时，判断为静态显示模式，当两帧图像数据不同时，判断为动态显示模式。
处理器还可以通过其他方法获取当前显示模式，预定时长的设定可以是终端预设的一个 合理值，也可以由用户自定义设定，本公开对预定时长的设定及获取当前显示模式的方法不作限定。
可选的，处理器每隔时间周期T对当前显示模式进行判断，本公开实施例对时间周期T的取值不作限定。
在步骤602中，响应于当前显示模式是静态显示模式，执行获取液晶面板的第一显示内容中的各个像素点的灰阶数值的步骤。
当处理器判断当前显示模式为静态显示模式时，认为当前显示的第一显示内容在预定时间内不会发生变化，则执行获取第一显示内容中各个像素点的灰阶数值的步骤。
可选的，当处理器判断当前显示模式为动态显示模式时，则不对液晶面板的刷新率进行调整。
在一个示例性的例子中，终端显示的是一个电子相册，第一显示内容为图像帧，每5秒会更新一帧新的图像帧，且液晶面板的第一刷新率为60Hz，以帧1、帧2……表示不同帧内容的图像帧，第一显示内容为帧1。
处理器获取到当前显示模式为静态显示模式，则获取第一显示内容的每个像素点的灰阶值，假设预定数值为5，第一显示内容的每个像素点的灰阶数值都为0，均小于预定数值5，即此时第一显示内容为黑色图像，则调整液晶面板的刷新率为第二刷新率1Hz，显示芯片每1s将图像帧刷新至液晶面板进行显示。
液晶面板第一次刷新后，显示内容仍为帧1，则认为此时的显示内容还是第一显示内容，保持刷新率为第二刷新率。
直到液晶显示屏第5次刷新后，显示内容更换为帧2，与第一显示内容的帧内容不同，即为第二显示内容，获取第二显示内容中每一个像素点的灰阶数值，假设存在有一个像素点的灰阶数值为10，大于预定数值，则调整液晶显示面板的刷新率为第一刷新率。
