背景技术
目前，液晶显示装置均是采用逐行扫描进行画面显示的，即是显示装置的栅极线根据扫描信息依次开启，通过数据线给每行像素电容充电。充电的电压不同，像素所呈现的灰阶便不同，给当前行的像素单元充电时，其他行的像素单元通过存储电容保持已经充好的电位，所有行充完就显示出一帧完整的图像。其中，数据线充放电会产生功耗，其中功耗P=1/2CFV2（C为电容容量，F为电压切换频率，V为电压），尤其是当显示装置显示画面为重载画面时，电压切换频率F的值较大，使得显示装置具有较大的功耗，严重时可能会因温度过高损坏驱动芯片。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，图 1是本申请实施例提供的一种显示方法的示意流程图。该显示方法应用于显示装置，使用该显示方法可以降低显示装置的功耗，同时还不会增加显示装置的成本。该显示方法具体运行在显示装置的屏驱动板（TCON）中，通过TCON运行该显示方法以驱动显示装置的显示屏显示画面。如图1所示，该显示方法包括步骤S101~S104。
S101、接收待显示画面的图像数据。
在本申请的实施例中，所述接收待显示画面的图像数据，具体为显示装置的TCON接收前端发送的待显示画面的图像数据，因为显示装置显示画面是一帧一帧的显示，因此TCON接收前端数据也是一帧一帧地接收图像数据，将其中1~2帧图像数据存储在TCON的存储器中，方便TCON的控制IC对该1~2帧图像数据进行分析处理，以便后续继续执行以下步骤。
需要说明的是，由于TCON在做超频驱动（over driver）时，一般也需要存储1~2帧待显示画面的图像数据，因此该方法不需要增加存储器容量，因此不会增加显示装置的硬件成本。
S102、获取所述图像数据中行图像数据对应的灰阶电压。
在本申请的实施例中，所述图像数据由多个像素点数据组成，在同一行中像素点的数据称为行图像数据，在同一列中像素点的数据称为列图像数据。获取所述图像数据中行图像数据对应的灰阶电压，是指以行单位的图像数据的灰阶电压，该灰阶电压其实不是真正的电压，而是二进制数据，但是该二进制数据的大小和实际灰阶电压的大小是成线性关系，可以根据高低为01数据统计判断其对应灰阶电压的高低，因此可以用该图像数据的二进制数据表示灰阶电压，使得获取所述图像数据中行图像数据对应的灰阶电压得以实现。
需要说明的是，所述灰阶电压可以为每一行图像数据中所有像素点的灰阶电压的平均值，也可以为其他表现形式，比如平方根或均方差形式等，在此不做限定。
S103、根据所述灰阶电压对所述行图像数据进行排序并生成排序标号。
在本申请的实施例中，根据所述灰阶电压对所述行图像数据进行排序并生成排序标号，具体可以采用根据所述行图像数据的灰阶电压的平均值大小对所述行图像数据进行排序。具体可以采用从大到小进行排序，也可以采用从小到大进行排序，或者其他的排序方式，在此不做限定。
假如采用从大到小进行排序，例如TCON的控制IC分析出来多个行图像数据中最高灰阶电压为aV，该最高灰阶电压对应的行图像数据在原图像数据中为第n行，则将第n行标记为1；多个行图像数据的第二高灰阶电压为bV，该第二高灰阶电压对应的行图像数据在原图像数据中为第m行，则将第m行标记为2，依次到所有行图像数据都标记完成，其中，a、b为具体数值，n、m为正整数，V表示电压伏特。则被新标记的1、2、3等号码即为所述排序标号。
S104、根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面。
现有的显示装置的扫描显示方式是依次从上至下对显示装置的栅极线逐行扫描的。如图2所示，图2为本申请提供的显示装置的阵列电路示意图，该阵列电路图包括由栅极线Sn（也称扫描线）和数据线Dm限定的多个像素单元，每个像素单元均包括TFT晶体管及由像素电极和公共电极形成LC电容，TFT根据栅极线扫描信号执行导通或关断以实现通过数据线给所述LC电容进行充电。从上而下逐行扫描，即是先扫描S1，打开与栅极线S1连接的TFT管，通过数据线Dm（Dm指所有的数据线）向S1行的LC电容充电，接着扫描S2，直至扫描至最后一条栅极线，完成一帧画面的显示。逐行扫描的缺点是会造成显示装置的数据线充放电时产生较大的功耗，其中该功耗表达式为：P=1/2CFV2（C为电容容量，F为电压切换频率，V为电压），由该表达式可见功耗和电压切换频率有关，电压切换频率越大，功耗就越大。当显示正常画面时，产生的功耗还不是很高；但当显示重载画面时，由于重载画面的电压切换频率F的值较大，就会使得显示装置产生较大的功耗，严重时可能会因温度过高而损坏驱动芯片。
在本申请的实施例中，根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面，由于根据灰阶电压对行图像数据进行了重新排序，避免了电压切换频率的值过于较大的问题，因此有效地降低了显示装置的功耗问题，即使是显示装置画面时，也不会产生过大的功耗。因此，该显示方法不进可以降低显示装置的功耗问题，还可以保护驱动芯片不会被烧坏。
上述本申请的实施例通过接收待显示画面的图像数据，分析并获取所述图像数据中行图像数据对应的灰阶电压，根据所述灰阶电压对所述行图像数据进行排序并生成排序标号，按照该排序标号依次扫描打开所述显示装置的栅极线以显示所述待显示画面。该显示方法改变了传统的至上而下逐行扫描的显示方式，而采用根据电压高低排序后按照新的排序标号进行扫描，由此降低了电压切换频率，进而降低了显示装置的功耗。
请参阅图3，图 3是本申请实施例提供的一种显示方法的另一示意流程图。该显示方法应用于显示装置，该显示装置可以为计算机的显示器，但不限于计算机的显示器。为了便于更好地理解本申请，在本实施例中，将使用计算机的显示器为例进行详细介绍。如图3所示，该显示方法包括步骤S201~S205。
S201、接收待显示画面的图像数据。
在本申请的实施例中，所述接收待显示画面的图像数据，可以理解为显示器接收计算机发送的待显示画面的图像数据。具体为显示器的屏驱动板接收计算机的主机发送的待显示画面的图像数据。该图像数据为二进制数据。显示器的屏驱动板接收计算机的主机发送的待显示画面的图像数据后，将所述图像数据存储在屏驱动板的存储器内，一般存储1~2帧数据，因此不会需要增加屏驱动板的存储器的容量。
S202、判断所述待显示画面的图像数据是否为重载画面的图像数据。
在本申请的实施例中，由于显示装置产生的功耗，主要是由待显示画面的图像性质造成，比如显示重载画面时会造成显示装置产生较大的功耗。因此该显示方法可以用于显示一些类似重载画面的特殊画面，对于正常画面还可以使用显示方法。将该显示方法和现有的显示方法相结合使用，可以获得更好的效果。因此在使用该显示方法时，需要先判断所述待显示画面的图像数据是否为重载画面的图像数据，并生成判断结果；若所述判断结果为重载画面，则执行步骤S203；若所述判断结果不是重载画面，则执行逐行扫描显示方式以显示所述待显示画面。
其中，判断是否为重载画面图像数据的方法，如图4所示，即步骤S202包括子步骤S202a和S202b。
S202a、判断待显示画面中重载子像素数目占子像素总数目的比例是否超过预设比例，其中，所述重载子像素为每列子像素中相邻且灰阶值之差超过预设阈值的子像素。
具体地，所述预设比例和所述预设阈值具体根据显示装置产生功耗实际大小进行设定，不同类别的显示装置不仅相同。比如，用图5作为重载画面的一个实例进行详细说明，图5为重载画面的其中一种形式。在图5中，第N-1行像素点表示亮像素点，第N行像素点表示暗像素点，第N+1行像素点表示亮像素点，第N+2行像素点表示暗像素点，整个显示器的画面全是亮暗行像素点交替形成，由于在列像素上时亮暗交替，显示画面中重载子像素数目占子像素总数目的比例将会达到100%。
S202b、若所述比例超过所述预设比例，则判定所述待显示画面的图像数据为重载画面的图像数据。
其中，图5中为显示屏显示的图像数据即满足待显示画面中重载子像素数目占子像素总数目的比例超过预设比例的条件，因此图5显示的画面即为重载画面。
此外，为了更详细地说明重载画面会使得显示装置产生较大的功耗，请参阅图6，图 6是现有的一种重载画面的数据线驱动信号的示意图。如图6所示，由于重载画面以栅极线自上而下亮暗交替显示画面，其对应数据线的驱动信号10将会采用类似高低电平驱动信号，采用这样的高低电平式驱动信号逐行扫描导致电压切换频率较大，因此会产生较大功耗。
S203、获取所述图像数据中行图像数据对应的灰阶电压。
在本申请的实施例中，若所述待显示画面的图像数据为重载画面的图像数据，则获取所述图像数据中行图像数据对应的灰阶电压。具体地，获取所述图像数据中行图像数据对应的灰阶电压，是指以行单位的图像数据的灰阶电压，该灰阶电压其实不是真正的电压，而是二进制数据，但是该二进制数据的大小和实际灰阶电压的大小是成线性关系，可以根据高低为01数据统计判断其对应灰阶电压的高低，因此可以用该图像数据的二进制数据表示灰阶电压，使得获取所述图像数据中行图像数据对应的灰阶电压得以实现。
需要说明的是，所述灰阶电压可以为每一行图像数据中所有像素点的灰阶电压的平均值，也可以为其他表现形式，比如平方根或均方差形式等，在此不做限定。
S204、根据所述灰阶电压的值由大到小对所述行图像数据进行排序并生成排序标号。
在本申请的实施中，根据所述灰阶电压从大到小进行排序。比如，TCON的控制IC分析出来多个行图像数据中最高灰阶电压为aV，该最高灰阶电压对应的行图像数据在原图像数据中为第n行，则将第n行标记为1；多个行图像数据的第二高灰阶电压为bV，该第二高灰阶电压对应的行图像数据在原图像数据中为第m行，则将第m行标记为2，依次到所有行图像数据都标记完成，其中，a、b为具体数值，n、m为正整数，V表示电压伏特。则被新标记的1、2、3等号码即为所述排序标号。
此外，可能出现不同的行图像数据的灰阶电压彼此相同的情况，如图7所示，步骤S204，即所述根据所述灰阶电压的值由大到小对所述行图像数据进行排序，具体包括子步骤S204a和S204b。其中，S204a、判断所述图像数据中的多个所述行图像数据是否有灰阶电压相同的行图像数据；S204b、若所述图像数据中的多个所述行图像数据有灰阶电压相同的行图像数据，则将所述灰阶电压相同的行图像数据按照原图像行号的顺序进行排序，其中所述原图像行号为所述行图像数据在所述图像数据中的行号。比如，比如第n行，n+3行，n+8行三个行图像数据是最高电压，那就按照此三行在原图像中的顺序进行排序标号，既是第n行标记为1，n+3标记为2，n+8标记为3。因此可以解决所述图像数据中出现灰阶电压相同的行图像数据的如何排序标号的问题。
S205、根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面。
在本申请的实施例中，根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面，由于根据灰阶电压对行图像数据进行了重新排序，避免了电压切换频率的值过于较大的问题，因此有效地降低了显示装置的功耗问题，即使是显示装置画面时，也不会产生过大的功耗。因此，该显示方法不进可以降低显示装置的功耗问题，还可以保护驱动芯片不会被烧坏。
具体地，如图8所示，图 8是本申请实施例提供的使用显示方法后重载画面的数据线驱动信号的示意图。由于根据灰阶电压对行图像数据进行了重新排序，使得数据线的驱动信号不采用图6中类似高低电平的驱动信息10，而是采用驱动信号20，假如有1080条栅极线（扫描线），采用本申请的显示方法显示重载画面时，540个高电平连续输出和540个低电平连续输出，这样就大大减小了电压切换频率的值，进而有效地降低了显示装置的功耗问题。
上述本申请的实施例通过接收待显示画面的图像数据，判断所述图像数据是否为重载画面的图像数据；若是，分析并获取所述图像数据中行图像数据对应的灰阶电压，根据所述灰阶电压对所述行图像数据进行排序并生成排序标号，按照该排序标号依次扫描打开所述显示装置的栅极线以显示所述待显示画面。该显示方法改变了传统的至上而下逐行扫描的显示方式，而采用根据电压高低排序后按照新的排序标号进行扫描，由此降低了重载画面导致电压切换频率较大的问题，进而降低了显示装置的功耗。
请参阅图9，图 9是本申请实施例提供的一种显示装置的示意性框图。该显示装置运行上述实施例中的显示方法，已达到更好的显示效果，比如针对重载图像，可以降低功耗问题。如图9所示，该显示装置包括：接收模块301、获取模块302、排序生成模块303和扫描显示模块304。
接收模块301，用于接收待显示画面的图像数据。具体为接收前端发送的待显示画面的1~2帧图像数据，因为显示装置显示画面是一帧一帧的显示，因此接收前端数据也是一帧一帧地接收图像数据。同时还可包括存储模块，用于将其中1~2帧图像数据存储在TCON的存储器中，方便TCON的控制IC对该1~2帧图像数据进行分析处理，由于TCON在做超频驱动（over driver）时，一般也需要存储1~2帧待显示画面的图像数据，现有的显示装置的TCON上的存储器可以满足容量需求，因此不会增加显示装置的硬件成本，存储1~2帧图像数据方便后续处理分析。
获取模块302，用于获取所述图像数据中行图像数据对应的灰阶电压。具体地，获取所述图像数据中行图像数据对应的灰阶电压，是指以行单位的图像数据的灰阶电压，该灰阶电压其实不是真正的电压，而是二进制数据，但是该二进制数据的大小和实际灰阶电压的大小是成线性关系，可以根据高低为01数据统计判断其对应灰阶电压的高低，因此可以用该图像数据的二进制数据表示灰阶电压，使得获取所述图像数据中行图像数据对应的灰阶电压得以实现。需要说明的是，所述灰阶电压可以为每一行图像数据中所有像素点的灰阶电压的平均值，也可以为其他表现形式，比如平方根或均方差形式等，在此不做限定。
排序生成模块303，用于根据所述灰阶电压对所述行图像数据进行排序并生成排序标号。其中，根据所述灰阶电压对所述行图像数据进行排序并生成排序标号，具体可以采用根据所述行图像数据的灰阶电压的平均值大小对所述行图像数据进行排序。具体可以采用从大到小进行排序，也可以采用从小到大进行排序，或者其他的排序方式，在此不做限定。假如采用从大到小进行排序，例如TCON的控制IC分析出来多个行图像数据中最高灰阶电压为aV，该最高灰阶电压对应的行图像数据在原图像数据中为第n行，则将第n行标记为1；多个行图像数据的第二高灰阶电压为bV，该第二高灰阶电压对应的行图像数据在原图像数据中为第m行，则将第m行标记为2，依次到所有行图像数据都标记完成，其中，a、b为具体数值，n、m为正整数，V表示电压伏特。则被新标记的1、2、3等号码即为所述排序标号。
扫描显示模块304，用于根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面。其中，根据所述排序标号依次扫描所述显示装置的栅极线以显示所述待显示画面，由于根据灰阶电压对行图像数据进行了重新排序，避免了电压切换频率的值过于较大的问题，因此有效地降低了显示装置的功耗问题，即使是显示装置画面时，也不会产生过大的功耗。因此，该显示方法不进可以降低显示装置的功耗问题，还可以保护驱动芯片不会被烧坏。
请参阅图10，图10是本申请实施例提供的一种显示装置的另一示意性框图。该显示装置运行上述实施例中的显示方法，已达到更好的显示效果，比如针对重载图像，可以降低功耗问题。如图10所示，显示装置400包括接收模块401、判断模块402、获取模块403、排序生成模块404、扫描显示模块405和显示模块406。
接收模块401，用于接收待显示画面的图像数据。其中，具体可以为接收计算机的主机发送的待显示画面的图像数据后，将所述图像数据存储在显示装置的屏驱动板的存储器内，一般存储1~2帧数据，因此不会需要增加屏驱动板的存储器的容量
判断模块402，用于判断所述待显示画面的图像数据是否为重载画面的图像数据。其中，当显示画面为重载画面时，由于重载画面的电压切换频率F的值较大，就会使得显示装置产生较大的功耗，严重时可能会因温度过高而损坏驱动芯片。因此有必要先判断所述待显示画面的图像数据是否为重载画面的图像数据。基于此，判断模块402包括：判断子模块4021和判定子模块4022。
具体地，判断子模块4021，用于判断待显示画面中重载子像素数目占子像素总数目的比例是否超过预设比例，其中，所述重载子像素为每列子像素中相邻且灰阶值之差超过预设阈值的子像素；判定子模块4022，用于若所述比例超过所述预设比例，则判定所述待显示画面的图像数据为重载画面的图像数据。
其中，判断模块402用于判断所述待显示画面的图像数据是否为重载画面的图像数据，生成判断结果。若所述判断结果为重载画面，则调用获取模块403；若所述判断结果不是重载画面，则调用显示模块406。
获取模块403，用于若所述待显示画面的图像数据为重载画面的图像数据，则获取所述图像数据中行图像数据对应的灰阶电压。具体地，若所述待显示画面的图像数据为重载画面的图像数据，则获取所述图像数据中行图像数据对应的灰阶电压。具体地，获取所述图像数据中行图像数据对应的灰阶电压，是指以行单位的图像数据的灰阶电压，该灰阶电压其实不是真正的电压，而是二进制数据，但是该二进制数据的大小和实际灰阶电压的大小是成线性关系，可以根据高低为01数据统计判断其对应灰阶电压的高低，因此可以用该图像数据的二进制数据表示灰阶电压，使得获取所述图像数据中行图像数据对应的灰阶电压得以实现。

此外，可能出现不同的行图像数据的灰阶电压彼此相同的情况，基于此，排序生成模块404包括电压判断子模块4041和排序子模块4042。
具体地，电压判断子模块4041，用于判断所述图像数据中的多个所述行图像数据是否有灰阶电压相同的行图像数据；排序子模块4042，用于若所述图像数据中的多个所述行图像数据有灰阶电压相同的行图像数据，则将所述灰阶电压相同的行图像数据按照原图像行号的顺序进行排序，其中所述原图像行号为所述行图像数据在所述图像数据中的行号。
