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示出了背景技术提供的一种液晶驱动电路的结构示意图。如图1所示，该液晶驱动电路包括m*n个液晶单元1、扫描驱动芯片2、m条扫描线21、数据驱动芯片3和n条数据线31。
液晶单元1按照m行n列阵列排布。每个液晶单元1包括：液晶像素电极11和TFT(Thin Film Transistor，薄膜晶体管)开关元件。TFT开关元件包括源极12、栅极13和漏极14。液晶像素电极11与TFT开关元件中的源极12相连。液晶像素电极11可以是红色液晶像素电极R、绿色液晶像素电极G或蓝色像素电极B。
扫描驱动芯片2包括m个扫描引脚，每个扫描引脚与一条扫描线21相连。每行液晶单元1对应一条扫描线21，扫描线21与对应一行液晶单元1中的栅极13相连。
数据驱动芯片3包括n个数据引脚，每个数据引脚与一条数据线31相连。每列液晶单元1对应一条数据线31，数据线31与对应一列液晶单元1中的漏极14相连。
在液晶驱动电路工作时，对于一帧画面，扫描驱动芯片2逐行向扫描线21发送扫描信号，从而让接收到扫描信号的扫描线21将对应一行的液晶单元置为工作状态。同时，数据驱动芯片3将该行液晶单元所对应的像素点的灰阶电压通过数据线31传输到对应的漏极13，从而数据驱动芯片3将对应的灰阶电压存入到液晶像素电极11上，使每个液晶像素电极11显示相应等级的灰阶，从而实现一帧图像的显示。
在图1描述的液晶驱动电路中，在开窗显示模式下，开窗区域中会显示目标内容，非开窗区域中会显示黑色。开窗区域是指将液晶显示屏中需要显示目标内容的部分区域，开窗区域小于液晶显示屏的全部显示区域，开窗区域通常为矩形。目标内容可以是系统时间、短信通知等。
但是对于液晶驱动电路而言，在开窗显示模式下，所有数据线2和扫描线3均处于正常的工作状态，只是将非开窗区域显示为黑色而已，使得液晶显示装置的功耗仍然较大。
图2A和图2B是根据一示例性实施例示出的一种液晶驱动电路的结构示意图。如图2A所示，该液晶驱动电路包括：m*n个按照行和列分布的液晶单元1、扫描驱动芯片2、m条按行分布的扫描线21、数据驱动芯片3、n条按列分布的数据线31、以及至少一个数据线开关4。
液晶单元1按照m行n列阵列排布。每个液晶单元1包括：液晶像素电机11和TFT开关元件。TFT开关元件包括源极12、栅极13和漏极14。液晶像素电极11与TFT开关元件中的源极12相连。液晶像素电极11可以是红色液晶像素电极R、绿色液晶像素电极 G或蓝色像素电极B。
扫描驱动芯片2包括m个扫描引脚，扫描引脚与一条扫描线21一一对应连接。每行液晶单元1对应一条扫描线21，每条扫描线21与对应行的液晶单元1的栅极13相连。
数据驱动芯片3包括n个数据引脚，数据引脚与数据线31一一对应连接。每列液晶单元1对应一条数据线31，每条数据线31与对应列的液晶单元1的漏极14相连。
存在至少一条数据线31与对应的数据引脚之间设置有数据线开关4。
在图2A实施例中，数据线开关4为n个，每条数据线31与数据驱动芯片3的数据引脚之间都设置有数据线开关4。数据线开关4还包括有控制端(图中未示出)。可选地，每个数据线开关4根据接收到的控制信号进行导通或截止。当数据线开关4导通时，对应的数据线31处于工作状态，能够接收到数据驱动芯片3的灰阶电压；当数据线开关4截止时，对应的数据线31处于不工作状态，无法接收到数据驱动芯片3的灰阶电压。
在图2B实施例中，只有符合第一条件的数据线31和对应的数据引脚之间设置有数据线开关4，其中，第一条件是数据线31的列与开窗区域不存在交集。
以n＝5为例，假设开窗区域(图中未示出)与中间3条数据线存在交集。也即，开窗区域与从左往右的第2条数据线、第3条数据线和第4条数据线存在交集，则第1条数据线和数据驱动芯片3的数据引脚之间都设置有数据线开关4、第5条数据线和数据驱动芯片3的数据引脚之间都设置有数据线开关4。
图3是根据本公开一示例性实施例示出的终端的结构示意图。该终端包括：DDIC(Display Driver Integrated Circuit，显示驱动集成电路)320和液晶驱动电路340。
该液晶驱动电路340是图2A或图2B所示出的液晶驱动电路。
该DDIC320与液晶驱动电路340中的扫描驱动芯片、数据驱动芯片和数据线开关分别电性相连。
图4是根据本公开一示例性实施例示出的显示方法的流程图。本实施例以该显示方法应用于包括有图3所示的液晶驱动电路的终端中来举例说明。该方法包括：
在步骤401中，在开窗显示模式下，通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压。
在开窗显示模式下，DDIC通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压。开窗区域是指将液晶显示屏中需要显示目标内容的部分区域，开窗区域小于液晶显示屏的全部显示区域，开窗区域通常为矩形。目标内容可以是系统时间、短信通知等。
在步骤402中，将与开窗区域不存在交集的数据线所对应的数据线开关设置为断开状态。
由于与开窗区域不存在交集的数据线不需要工作，DDIC还将与开窗区域不存在交集的数据线所对应的数据线开关设置为断开状态。
在步骤403中，通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压。
在一条扫描线处于被扫描状态时，对于该行扫描线所对应的一行液晶单元，DDIC还同时根据待显示内容生成每个数据线上对应的灰阶电压，并通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压，以便显示出这一行显示内容。
DDIC将每一行扫描线扫描一次，即可显示出一帧显示内容。
需要说明的是，本实施例不限定步骤402与步骤401、403之间的执行先后关系。
综上所述，本实施例提供的显示方法，在开窗显示模式下，通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压；将与开窗区域不存在交集的数据线所对应的数据线开关设置为断开状态；通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压；解决了在开窗显示模式下，非开窗区域的扫描线和数据线仍处于工作状态导致的功耗浪费问题；达到了在开窗显示模式下，只有与开窗区域有交集的扫描线和数据线处于工作状态，降低了功耗的效果。
图5是根据本公开一示例性实施例示出的显示方法的流程图。本实施例以该显示方法应用于包括有图3所示的液晶驱动电路的终端中来举例说明。该方法包括：
在步骤501中，在开窗显示模式下，生成与开窗区域的大小所对应的显示内容。
在开窗显示模式下，DDIC仅需要生成与开窗区域的大小所对应的显示内容即可。比如，开窗区域的大小为320像素*240像素，则仅需要生成320像素*240像素的显示内容即可。
在步骤502中，通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压。
在开窗显示模式下，DDIC读取开窗区域的位置，根据开窗区域的位置，检测与开窗区域存在交集的扫描线，通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压。
比如：假定扫描驱动芯片中从上往下存在10条扫描线，而开窗区域的位置位于从第2行至第5行，则通过扫描驱动芯片向第2条至第5条扫描线发送扫描电压即可。
可选地，DDIC通过扫描驱动芯片控制扫描电压的开始输出位置和输出次数。
其中，开始输出位置是按照从上往下的顺序与开窗区域存在交集的第一条扫描线所对应的扫描引脚；输出次数等于与开窗区域存在交集的扫描线的条数。
开始输出位置是指开窗区域最顶端所在的扫描线；输出次数是指开窗区域共占用的扫描线的条数。
比如：假定扫描驱动芯片中从上往下存在10条扫描线，而开窗区域的位置是从第2行至第5行，则开始输出位置是指第2条扫描线，而输出次数是3次。
在步骤503中，将与开窗区域不存在交集的数据线所对应的数据线开关设置为断开状态。
与开窗区域不存在交集的数据线是指开窗区域列方向上未占用的数据线；设置为断开 状态是将数据线处于断路的状态。
比如：假定数据驱动芯片中从左往右存在10条数据线，而开窗区域从左往右从第3列至第6列，则与开窗区域不存在交集的数据线为从左往右第1条、第2条、第7-10条，即将该数据线上对应的数据线开关设置为断开状态。
在步骤504中，通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压。
在一条扫描线处于被扫描状态时，对于该行扫描线所对应的一行液晶单元，DDIC还同时根据待显示内容生成每个数据线上对应的灰阶电压，并通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压，以便显示出这一行显示内容。
DDIC将每一行扫描线扫描一次，即可显示出一帧显示内容。
需要说明的是，本实施例不限定步骤503与步骤502、504之间的执行先后关系。
综上所述，本实施例提供的显示方法，在开窗显示模式下，通过扫描驱动芯片向与开窗区域存在交集的扫描线发送扫描电压；将与开窗区域不存在交集的数据线所对应的数据线开关设置为断开状态；通过数据驱动芯片向与开窗区域存在交集的数据线发送灰阶电压；解决了在开窗显示模式下，非开窗区域的扫描线和数据线仍处于工作状态导致的功耗浪费问题；达到了在开窗显示模式下，只有与开窗区域有交集的扫描线和数据线处于工作状态，降低了功耗的效果。
本实施例还通过仅生成与开窗区域相同大小的显示内容，不需要生成整个屏幕的显示内容，有效减少了计算量，从而也降低了功耗的效果。
