具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点,下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明,但是,本发明还可以采用其他不同于在此描述的方式来实施,因此,本发明的保护范围并不受下面公开的具体实施例的限制。
如图2所示,根据本发明一个实施例的显示基板10包括M条数据线(例如S1、S2、S3、...、SM)和N条栅线(例如G1、G2、G3、...、GN),M条数据线和N条栅线交叉界定多个像素。如图1所示,显示基板10还包括:
分辨率调整模块11,该分辨率调整模块11包括:
分辨率确定单元111,配置为确定目标分辨率,例如可以根据接收到的指令确定目标分辨率;
信号输入调整单元112,配置为根据所述目标分辨率和M确定参数a以及根据所述目标分辨率和N确定参数b,并且向M条数据线中沿栅线延伸方向每隔a条数据线的数据线输入数据信号,以及向N条栅线中沿数据线延伸方向每b条栅线输入相同的扫描信号,其中,M、N均大于1,a大于等于0,b大于等于1。
根据本发明的另一实施例,信号输入调整单元112还配置为向M条数据线中的每条数据线输入数据信号,以及向N条栅线中的每两条 相邻的栅线输入不同的扫描信号。
例如,如图3所示,向栅线G1和G2输入不同的扫描信号,向栅线G1输入的扫描信号比向栅线G2输入的扫描信号提前一个行同步信号(即Hsync)。向栅线G1输入的扫描信号包括STVL、CKL1、CKL2、Gdummy-1、G11等信号,向栅线G2输入的扫描信号包括STVR、CKR1、CKR2、Gdummy0、G22等信号,其中STVL与STVR不同,CKL1与CKR1不同、CKL2与CKR2不同、Gdummy-1与Gdummy0不同、G11与G22不同。

根据本发明的另一实施例,目标分辨率为A*B,
在M条数据线中的每2条数据线对应2列像素时,a=M/A-1;
在N条栅线中的每2条栅线对应2行像素时,b=N/B;
在M条数据线中的每1条数据线对应2列像素时,a=M/A-2;
在N条栅线中的每1条栅线对应2行像素时,b=N/B-1,
其中,A和B均大于1。
在不需要将显示画面以最大分辨率显示的情况下,可以通过本实施例中的分辨率调整模块11来调节分辨率。例如,在每2条数据线对应2列像素且每2条栅线对应2行像素的情况下,如果M=2160,N=1440,目标分辨率为A*B=1080*720,那么可以向2160条数据线中沿栅线延伸方向每隔2160/1080-1=1条数据线的数据线输入数据信号,以及向1440条栅线中沿数据线延伸方向每1440/720=2条栅线输入相同的扫描信号。需要说明的是,在N不能整除B时,例如N/B=3/2,可以通过硬件来调整栅线的开关。例如,在每3行栅线中关闭1行栅线。
例如,向S1、S3、S5等奇数列数据线输入数据信号,向栅线G1和G2输入第一扫描信号,向栅线G3和G4输入第二扫描信号,...。需要说明的是,在这种情况下,S2、S4、S6等偶数列数据线仍需输入高电压,以保持其对应像素处于点亮状态。在所输入的扫描信号不同的两条相邻的栅线中,扫描信号相差一个行同步信号。
信号输入调整单元112可以包括一个或多个集成电路。例如,信号输入调整单元112可以包括一个用于调整扫描信号输入方式的集成 电路和一个用于调整数据信号输入方式的集成电路。信号输入调整单元112也可以仅包括一个用于调整扫描信号输入方式的集成电路,而数据信号输入方式的调整则由显示基板的驱动集成电路实现。
通过上述方式对扫描信号和数据信号的输入进行调整,可以使得显示基板的横向分辨率变为原来的1/2,纵向分辨率也变为原来的1/2,最终使得分辨率由2160*1440变为1080*720。
例如,向栅线G1和G2输入的第一扫描信号可以如图4所示。向栅线G1输入的扫描信号包括STVL、CKL1、CKL2、Gdummy-1、G11等信号,向栅线G2输入的扫描信号包括STVR、CKR1、CKR2、Gdummy0、G22等信号。其中STVL与STVR相同,CKL1与CKR1相同、CKL2与CKR2相同、Gdummy-1与Gdummy0相同、G11与G22相同。
通过比较图3和图4可知,图4中的信号输入方式明显比图3中的信号输入方式简单。因此,根据本实施例的技术方案,可以通过简化信号输入方式来调整分辨率,从而减少了与信号相对应的电压的配置和调节过程,进而降低了功耗。
在通过一条数据线向两列像素传输数据信号且通过一条栅线向两行像素传输扫描信号的像素结构中,即,在每1条数据线对应2列像素且每1条栅线对应2行像素的情况下,如果M=2160,N=1440,目标分辨率为A*B=1080*720,那么可以向2160条数据线中沿栅线延伸方向每隔2160/1080-2=2-2=0条数据线输入数据信号,即,向每条数据线都输入数据信号,以及向1440条栅线中沿数据线延伸方向每1440/720-1=2-1=1条栅线输入相同的扫描信号,即,向每条栅线都输入扫描信号。需要说明的是,在这种情况下,还需要调整数据线传输数据信号的目标,以及调整栅线传输扫描信号的目标。例如,一条数据线向与其对应的两列像素中的一列像素传输数据信号,一条栅线向与其对应的两行像素中的一行像素传输扫描信号。
根据本发明的另一实施例,相邻栅线的扫描信号的输入端位于显示基板的不同侧。由此,能够简化显示基板中的布线。
根据本发明的另一实施例,信号输入调整单元112还配置为通过子像素渲染法向与输入数据信号的数据线相邻的数据线输入像素借用信号。
通过子像素渲染法驱动与传输数据信号的数据线所对应的像素的相邻列中的子像素,可以实现视觉上的分辨率大于物理分辨率,从而在降低功耗的同时,提升显示效果。
根据本发明的另一实施例,显示基板10还包括:
识别模块12,配置为识别显示内容的类型;
提示模块13,配置为在显示内容的类型为静态图像时生成降低分辨率的提示信息。
由此,可以在识别出显示内容的类型为静态图像时,自动提示用户是否降低分辨率以降低功耗。提示信息可以传输到显示基板10中的其它模块或单元。提示信息也可以以文字或图像的方式进行显示,或者以声音或灯光的方式进行提示。
根据本发明的另一实施例,分辨率调整模块11还包括:
模拟调整单元113,配置为在接收到降低分辨率的提示信息时,根据比当前显示内容的分辨率小的多个预设分辨率来模拟调整当前显示内容的分辨率;
比较单元114,配置为比较模拟调整后的显示内容与当前显示内容的相似度,获取与当前显示内容的相似度大于预设值的模拟调整后的显示内容所对应的预设分辨率中的最小分辨率。
信号输入调整单元112可以将当前显示内容的分辨率调整为最小分辨率。
例如,当前显示内容的分辨率为2160*1440,比当前显示内容的分辨率小的多个预设分辨率分别为1440*720和720*360。在将当前显示内容的分辨率模拟调整至1440*720和720*360后,如果模拟调整后的显示内容与当前显示内容的相似度均大于预设值,那么则获取其中的最小分辨率,即720*360。信号输入调整单元112可以将当前显示内容的分辨率调整为720*360。其中,模拟调整并不会对当前显示内容的分辨率进行实际调整,而是通过计算得到将当前显示内容的分辨率调整至相应分辨率后的显示内容。
根据本实施例,一方面可以保证调整分辨率之后的显示内容与当前显示内容的相似度较高,从而不会对用户的观看效果造成影响;另一方面可以在满足相似度的分辨率中自动选择最小分辨率进行调整,而显示内容的分辨率越小,相应的功耗也就越低,从而在保证用户观 看效果的同时,使得功耗最小化。
根据本发明的另一实施例,显示基板10还包括:计算模块14,配置为计算当前显示内容的第一功耗和分辨率为最小分辨率的显示内容的第二功耗,
其中,提示模块13还配置为生成第一功耗和第二功耗的提示信息。
由此,便于用户直观地了解降低分辨率所对应的功耗降低收益。例如,在显示基板设置在移动终端中的情况下,提示信息可以包括当前分辨率下的剩余电量以及调整至最小分辨率后的剩余电量。
本发明实施例还提出了一种显示装置,包括上述显示基板。
需要说明的是,本实施例中的显示装置可以为:电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明实施例还提出了一种显示基板分辨率调整方法,显示基板包括M条数据线和N条栅线,所述M条数据线和所述N条栅线交叉界定多个像素,所述方法包括:
确定目标分辨率;以及

根据本发明的另一实施例,目标分辨率为A*B,
在M条数据线中的每2条数据线对应2列像素时,a=M/A-1;
在N条栅线中的每2条栅线对应2行像素时,b=N/B;
在M条数据线中的每1条数据线对应2列像素时,a=M/A-2;
在N条栅线中的每1条栅线对应2行像素时,b=N/B-1,
其中,A和B大于1。
根据本发明的另一实施例,显示基板分辨率调整方法还包括:
向M条数据线中的每条数据线输入数据信号,以及向N条栅线中每两条相邻的栅线输入不同的扫描信号。
根据本发明的另一实施例,显示基板分辨率调整方法还包括:通过子像素渲染法向与输入数据信号的数据线相邻的数据线输入像素借 用信号。
如图5所示,根据本发明的另一实施例,上述显示基板分辨率调整方法还包括:
S1,识别显示内容的类型;
S2,在显示内容的类型为静态图像时,生成降低分辨率的提示信息。
根据本发明的另一实施例,显示基板分辨率调整方法还包括:
S3,在生成降低分辨率的提示信息时,根据比当前显示内容的分辨率小的多个预设分辨率来模拟调整当前显示内容的分辨率;
S4,比较模拟调整后的显示内容与当前显示内容的相似度,获取与当前显示内容的相似度大于预设值的模拟调整后的显示内容所对应的预设分辨率中的最小分辨率,将当前显示内容的分辨率调整为最小分辨率。
根据本发明的另一实施例,上述显示基板分辨率调整方法还包括:
计算当前显示内容的第一功耗和分辨率为最小分辨率的显示内容的第二功耗;以及
生成第一功耗和第二功耗的提示信息。
以上结合附图详细说明了本发明的技术方案。根据本发明的技术方案,可以通过调整数据信号和扫描信号的输入方式来降低分辨率,从而简化数据信号电压和扫描信号电压的配置方式和输入方式,降低相应功耗。
