【具体实施方式】
本发明公开一种显示装置，优选地，该显示装置优选为OLED显示装置。当然，本发明并不限定该显示装置为OLED显示装置，在其他实施例中，该显示装置还可以是其他类型的显示装置。
如图2所示，图2是本发明显示装置的结构示意图。显示装置包括格式转换器11、扫描驱动器12、数据驱动器13以及显示面板14。
格式转换器11用于获取每一帧原数据帧，并对原数据帧进行格式转换，以转换成不同格式的转换数据帧。在本实施例中，格式转换器11设置在TCON（时序控制器）中，在时序控制器为显示面板14中的扫描驱动器12和数据驱动器13提供必要的时序控制信号时，格式转换器11对原数据帧进行格式转换。应理解，格式转换器11也可以独立设置在显示装置内。
如图3所示，格式转换器11包括获取模块111、控制模块112和转换模块113。获取模块111用于获取每一帧原数据帧。转换模块113预先设置有至少2个转换单元，具体地，转换模块113可以包括第一转换单元1131、第二转换单元1132、第三转换单元或者更多的转换单元。转换模块113用于通过至少2个转换单元对原数据帧进行格式转换，以转换成不同格式的转换数据帧。控制模块112用于控制转换模块113选择至少2个转换单元中的一者对原数据进行格式转换。
在本实施例中，控制模块112控制转换模块113按顺序选择至少2个转换单元中的一者对原数据进行格式转换，具体而言，获取模块111获取第一帧原数据帧时，控制模块112控制转换模块113选择第一转换单元1131对原数据进行格式转换；获取模块111获取第二帧原数据帧时，控制模块112控制转换模块113选择第二转换单元1132对原数据进行格式转换；获取模块111获取第三帧原数据帧时，控制模块112控制转换模块113选择第三转换单元对原数据进行格式转换，依次类推。当然，在其他实施例中，控制模块112可以控制转换模块113不按顺序选择至少2个转换单元中的一者对原数据进行格式转换，具体而言，获取模块111获取第一帧原数据帧时，控制模块112控制转换模块113选择第二转换单元1132对原数据进行格式转换；获取模块111获取第二帧原数据帧时，控制模块112控制转换模块113选择第一转换单元1131对原数据进行格式转换；获取模块111获取第三帧原数据帧时，控制模块112控制转换模块113选择第三转换单元对原数据进行格式转换，依次类推。
控制模块112根据标记变量flag来控制转换模块113选择转换单元对原数据进行格式转换。具体如，当标记变量flag为第一值时，控制模块112控制转换模块113选择第一转换单元1131对原数据进行格式转换；当标记变量flag为第二值时，控制模块112控制转换模块113选择第二转换单元1132对原数据进行格式转换，当标记变量flag为第三值时，控制模块112控制转换模块113选择第三转换单元对原数据进行格式转换。
扫描驱动器12与显示面板14连接，用于对显示面板14进行信号扫描。
数据驱动器13分别与格式转换器11和显示面板14连接，用于从格式转换器11获取转换数据帧后，驱动显示面板14的像素单元发光。
显示面板14用于在获取每一帧经过格式转换器11转换的转换数据帧时，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光。应理解，像素单元包括3个子像素单元。
为了更好说明本发明，本实施例以转换模块113包括第一转换单元1131和第二转换单元1132为例进行说明，显示面板14在获取第一帧经过第一转换单元1131转换的转换数据帧时，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光；显示面板14在获取第二帧经过第二转换单元1132转换的转换数据帧时，显示面板14的一部分像素单元不发光，显示面板14的另一部分像素单元发光。也就是说，本实施例的显示面板14需要获取二帧转换数据帧，显示面板14的像素单元才能全部都发光。
在本实施例中，为了不影响显示面板14的发光效果，显示面板14在获取每一帧经过格式转换器11转换的转换数据帧时，显示面板14的一半像素单元发光，显示面板14的另一半像素单元不发光。优选地，为了显示面板14的像素单元的发光均匀，显示面板14在获取每一帧经过格式转换器11转换的转换数据帧时，在显示面板14的一半像素单元发光，显示面板14的另一半像素单元不发光情况下，同时，显示面板14的每一个发光的像素单元与显示面板14的每一个不发光的像素单元相邻设置。具体以图4和图5的第一像素单元141、第二像素单元142、第三像素单元143和第四像素单元144为例，如显示面板14在获取第一帧经过第一转换单元1131转换的转换数据帧时，显示面板14的第一像素单元141和第三像素单元143不发光，显示面板14的第二像素单元142和第四像素单元144发光（如图4所示）；而显示面板14在获取第二帧经过第二转换单元1132转换的转换数据帧时，显示面板14的第一像素单元141和第三像素单元143发光，显示面板14的第二像素单元142和第四像素单元144不发光（如图5所示）。
应理解，在其他实施例中，为了进一步减缓显示面板14的老化速度，转换模块113可以包括第一转换单元1131、第二转换单元1132和第三转换单元。显示面板14在获取每一帧经过格式转换器转换的转换数据帧时，显示面板14的三分之一像素单元发光，显示面板14剩下的三分之二像素单元不发光。也就是说，显示面板14需要获取三帧转换数据帧，显示面板14的像素单元才能全部都发光。具体而言，显示面板14获取第一帧经过第一转换单元1131转换的转换数据帧时，显示面板14的三分之一像素单元发光；显示面板14获取第二帧经过第二转换单元1132转换的转换数据帧时，显示面板14的剩下三分之二中的一半像素单元发光；显示面板14获取第三帧经过第三转换单元转换的转换数据帧时，显示面板14的剩下三分之一像素单元发光，从而能够实现降低显示面板14的像素单元发光时间。
也就是说，显示面板14的像素单元全部都发光所要获取的转换数据帧的帧数与转换模块113包括的转换单元的个数相同。即转换模块113包括多少个转换单元，显示面板14就需要获取与转换单元相同数量的转换数据帧，显示面板14的像素单元才能全部都发光，如转换模块113包括4、5、6、7个转换单元，显示面板14就需要获取4、5、6、7个转换数据帧，显示面板14的像素单元才能全部都发光。
可替换的，本发明并不限定显示面板14需要获取与转换单元的数量相同的转换数据帧，显示面板14的像素单元才能全部都发光，可以根据实际需要选择更多帧转换数据帧实现显示面板14的像素单元全部都发光。具体如，在转换模块113只包括第一转换单元1131和第二转换单元1132的情况下，格式转换器11获取第一帧原数据帧时，格式转换器11利用第一转换单元1131对原数据帧进行转换，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光；格式转换器11获取第二帧原数据帧时，格式转换器11利用第一转换单元1131对原数据帧进行转换，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光；格式转换器11获取第三帧原数据帧时，格式转换器11利用第二转换单元1132对原数据帧进行转换，显示面板14的一部分像素单元不发光，显示面板14的另一部分像素单元发光。
本发明在不改变像素单元的结构的前提下，对每一帧原数据帧进行处理，以将原数据帧对应的原始画面数据经过转换后再送入显示面板14显示，且每一帧只有部分像素单元发光，所有像素单元交替显示，从而在显示面板14工作时间相同的前提下，使每一个显示面板14的使用时间都缩短。
进一步地，如图5所示，图5是本发明显示装置的驱动方法的流程示意图。图5的方法对应图2的显示装置，该方法包括以下步骤：
步骤S101：格式转换器11获取每一帧原数据帧，并对原数据帧进行格式转换，以转换成不同格式的转换数据帧。
如图6所示，图6是图5中步骤S101的子步骤流程示意图，该子步骤包括：
步骤S1011：格式转换器11获取每一帧原数据帧。
步骤S1012：格式转换器11选择至少2个转换单元中的一者。
在步骤S1012中，格式转换器11可以按顺序选择至少2个转换单元中的一者，也可以不按顺序选择至少2个转换单元中的一者。
步骤S1013：格式转换器11通过至少2个转换单元中的一者对原数据帧进行格式转换，以转换成不同格式的转换数据帧。
步骤S102：显示面板14在获取每一帧经过格式转换器11转换的转换数据帧时，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光。
在本实施例中，显示面板14的像素单元全部都发光所要获取的转换数据帧的帧数与转换模块113包括的转换单元的个数相同。即转换模块113包括多少个转换单元，显示面板14就需要获取与转换单元相同数量的转换数据帧，显示面板14的像素单元才能全部都发光。如转换模块113包括2、3、4、5、6、7个转换单元，显示面板14就需要获取2、3、4、5、6、7个转换数据帧，显示面板14的像素单元才能全部都发光。
以转换模块113包括第一转换单元1131和第二转换单元1132为例，显示面板14需要获取二帧转换数据帧，显示面板14的像素单元才能全部都发光。具体如，显示面板14在获取第一帧经过第一转换单元1131转换的转换数据帧时，显示面板14的一部分像素单元发光，显示面板14的另一部分像素单元不发光；显示面板14在获取第二帧经过第二转换单元1132转换的转换数据帧时，显示面板14的一部分像素单元不发光，显示面板14的另一部分像素单元发光。在步骤S102中，为了不影响显示面板14的发光效果，显示面板14在获取每一帧经过格式转换器11转换的转换数据帧时，显示面板14的一半像素单元发光，显示面板14的另一半像素单元不发光。进一步地，为了显示面板14的像素单元的发光均匀，显示面板14在获取每一帧经过格式转换器11转换的转换数据帧时，在显示面板14的一半像素单元发光，显示面板14的另一半像素单元不发光情况下，同时，显示面板14的每一个发光的像素单元与显示面板14的每一个不发光的像素单元相邻设置。
应理解，在其他实施例中，为了进一步减缓显示面板14的老化速度，显示面板14在获取每一帧经过格式转换器转换的转换数据帧时，显示面板14的三分之一像素单元发光，显示面板14剩下的三分之二像素单元不发光。也就是说，显示面板14需要获取三帧转换数据帧，显示面板14的像素单元才能全部都发光。
可替换的，本发明并不限定显示面板14需要获取与转换单元的数量相同的转换数据帧，显示面板14的像素单元才能全部都发光，可以根据实际需要选择更多帧转换数据帧实现显示面板14的像素单元全部都发光，如显示面板14的像素单元全部都发光所要获取的转换数据帧的帧数与转换模块113包括的转换单元的个数不相同。
综上所述，本发明的显示装置包括格式转换器和显示面板，格式转换器用于获取每一帧原数据帧，并对原数据帧进行格式转换，以转换成不同格式的转换数据帧；显示面板用于在获取每一帧经过格式转换器转换的转换数据帧时，显示面板的一部分像素单元发光，显示面板的另一部分像素单元不发光。通过上述方式，本发明通过对原数据帧进行格式转换以控制显示面板在获取每一帧转换数据帧时，显示面板的一部分像素单元发光，显示面板的另一部分像素单元不发光，能够减少显示面板的像素单元的发光时间，有效减缓显示面板的老化速度。
以上仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
