Description

一种显示面板及其驱动方法、驱动装置 技术领域
本公开公开涉及一种显示面板及其驱动方法、驱动装置。
背景技术
随着显示技术的不断发展,对显示面板的显示分辨率的要求也越来越高。根据显示分辨率,显示面板可以分为超高清显示面板(Ultra High Definition,UHD)、全高清显示面板(Full High Definition,FHD)和高清显示面板(High Definition,FHD)。但是,发明人已知的模组产品(module product)中,大部分采用不变的像素结构,即分辨率不可变。例如,如果显示面板为超高清显示面板,且需要显示的图像的分辨率比较低,但仍属于高清显示的分辨率范围内,则在将该图像显示在该超高清显示面板上时,需要通过计算将该图像的分辨率提高到与显示面板分辨率相同的值,再进行显示。
所以,发明人已知的模组产品中,显示面板的分辨率不会变化,只能进行超高清显示,或者全高清显示,或者高清显示。因此,在某些情况下,例如在显示视频时,显示面板一直处于超高清的显示状态,而不会灵活地改变显示分辨率,从而增加显示面板的显示功耗。
综上所述,发明人已知的显示面板不能选择性地降低显示面板的显示分辨率,且增加了显示面板的显示功耗。

具体实施方式
为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开作进一步地详细描述。显然,所描述的实施例仅仅是本公开的一部分实施例,而不是全部的实施例。基于本公开的实施例,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它实施例,都属于本公开保护的范围。
实施例1
图1示出根据本公开的实施例的显示面板,该显示面板包括交叉设置的栅线11和数据线12。该显示面板还包括连接于不同栅线11之间的至少一个开关单元13(图1中仅画出了几个,但不限于该图中的连接方式),开关单元13用于控制至少两行栅线11是否导通。图1中由数据线与栅线交叉设置的区域中包括的方块代表亚像素单元。该显示面板还包括分别与开关单元的控制端和数据线的输入端相连的驱动控制模块14。驱动控制模块14包括与开关单元的控制端一一连接的第一输出端141,其中,驱动控制模块14通过第一输出端141输出用于控制对应的开关单元13是否导通的控制信号;并且,驱动控制模块14还包括与数据线的输入端一一连接的第二输出端142,其中,驱动控制模块14根据开关单元13的开关状态,决定是否通过第二输出端142将图像信号输出给相应的数据线。
需要说明的是,在本公开的实施例中,在不同栅线之间设置至少一个开关单元意味着可以在显示面板中的一对相邻的两行栅线之间设置一个开关单元,也可以在显示面板中的若干对相邻的两行栅线之间分别设置一个开关单元,或者也可以在显示面板中的每对相邻的两行栅线之间均设置一个开关单元;然而,设置几个开关单元,本公开不做限定。另外,开关单元用于控制该开关单元连接的两行栅线导通,使得该两行栅线同时进行扫描,因此开关 单元可以只设置在相邻的两行栅线之间。
当一个开关单元导通时,该开关单元连接的两行栅线导通,使得该两行栅线同时扫描该两行栅线对应的子像素单元。根据该开光单元的导通状态,当向数据线输入图像信号时,只需要向该两行栅线对应的一个数据线进行输入。向该两行栅线对应的一个数据线进行输入可以是如果前两行栅线导通,则将图像信号输入给前两个数据线中的一个。
根据本公开的实施例的显示面板,在不同栅线之间设置至少一个开关单元,用以控制至少两行栅线是否导通。开关单元与驱动控制模块的第一输出端一一连接,从而接收由驱动控制模块输出的用于控制该开关单元是否导通的控制信号;并且显示面板中的数据线与驱动控制模块的第二输出端一一连接,以接收由驱动控制模块输出的图像信号。当开关单元接收到由驱动控制模块通过第一输出端输出的用于控制该开关单元导通的控制信号时,该开关单元导通,使得该开关单元连接的两行栅线同时扫描;根据该开关单元的导通状态,驱动控制模块将图像信号输出给该两行栅线对应的数据线,从而降低显示面板的显示分辨率,并降低显示面板的显示功耗。
参见图2,在每对相邻的两行栅线11之间均设置有开关单元13。
通过在每两行栅线之间均设置开关单元,并且通过开关单元的导通,更大地降低了显示面板的显示分辨率,从而降低显示面板的显示功耗。
参见图3,开关单元13为薄膜晶体管(TFT)。对于每一薄膜晶体管,该薄膜晶体管的源极(S)和漏极(D)分别连接与该薄膜晶体管相邻的两行栅线11,该薄膜晶体管的栅极(G)连接驱动控制模块14的第一输出端。
需要说明的是,开关单元用于使相邻的两行栅线进行导通,所以本公开中的开关单元不仅限于为薄膜晶体管,使得能够通过控制信号来导通该开关单元连接的两行栅线的器件都属于本公开的保护范围。
驱动控制模块14用于:
根据信号源发送的待显示图像的分辨率,确定该待显示图像的分辨率所对应的显示模式;
根据显示模式,确定需要导通和关断的开关单元,并通过第一输出端输出用于控制对应的开关单元是否导通的控制信号,以及根据开关单元的开关状态,通过第二输出端将图像信号输出给相应的数据线。
需要说明的是,本公开实施例中的驱动控制模块为驱动IC(DIC)或者用于驱动栅极的Gate IC。当然,本公开实施例中“根据信号源发送的待显示图像的分辨率,确定该待显示图像的分辨率所对应的显示模式”可以由驱动IC或Gate IC或者应用处理器(AP)来执行,本公开不做限定。
本公开实施例中的待显示图像是指需要由面板显示但还没有显示的图像,图像信号是指待显示图像的需要在显示面板显示的图像内容。
通过驱动控制模块对开关单元的控制以及对数据线的控制,降低显示面板的显示分辨率,并降低显示面板的显示功耗。驱动控制模块根据从信号源发送的待显示图像的分辨率,确定该待显示图像的分辨率所对应的显示模式,然后根据该显示模式,确定需要导通和关断的开关单元,并发送控制信号给每一开关单元,以及根据开关单元的导通状态,将待显示图像的图像信号发送给相应地数据线。
驱动控制模块14还用于:
接收从信号源发送的待显示图像的电压信号;
根据相邻两帧的待显示图像的电压信号,确定当前的图像显示模式,其中图像显示模式为静态显示模式或动态显示模式;
当图像显示模式为静态显示模式时,根据该待显示图像的分辨率,确定需要关断的开关单元,并通过第一输出端输出用于控制相应的开关单元导通或关断的控制信号,以及根据开关单元的开关状态,通过第二输出端将图像信号输出给相应的数据线。
在本公开的实施例中,静态显示模式可以是显示静态的图片或者文字等静态的信息的模式,动态显示模式可以是显示动态的图片或者视频等信息的模式。
本公开实施例中的驱动控制模块还用于:接受从信号源发送的待显示图像的电压信号;根据该电压信号,判断该待显示图像的图像显示模式;当确定待显示图像的图像显示模式为静态显示模式时,根据该图像的分辨率,确定需要关断的开关单元,并将控制开关单元的关断的控制信号发送给相应的开关单元,并且根据该开关状态,将图像信号发送给相应的数据线。由此,使得当待显示图像的图像显示模式为静态显示模式时,通过开关单元的关断,使显示面板中的显示分辨率从低变为高,从而提高待显示图像静态显示时的 分辨率,提高用户的体验感。
驱动控制模块14还用于:
当图像显示模式为动态显示模式时,提高传输图像的帧频。
当驱动控制模块确定待显示图像的图像显示模式为动态显示模式时,提高传输待显示图像的帧频,以提高显示面板在显示视频等动态图像时的流畅度,从而提高用户的体验感。
综上所述,在本公开实施例提供的显示面板中,在不同栅线之间设置至少一个开关单元,用以控制两行栅线是否导通;每一开关单元与驱动控制模块的第一输出端一一连接,从而接收从驱动控制模块输出的用于控制该开关单元是否导通的控制信号;以及,显示面板中的每一数据线与驱动控制模块的第二输出端一一连接,以接收从驱动控制模块输出的图像信号。当开关单元接收到由驱动控制模块通过第一输出端输出的用于控制该开关单元导通的控制信号时,该开关单元导通,使得该开关单元连接的两行栅线同时进行扫描,同时,根据该开关单元的导通状态,驱动控制模块将图像信号输出给该两行栅线对应的数据线,从而降低显示面板的显示分辨率,并降低显示面板的显示功耗。另外,驱动控制模块还接受从信号源发送的待显示图像的电压信号,并根据该电压信号,判断该待显示图像的图像显示模式;当确定待显示图像的图像显示模式为静态显示模式时,根据该图像的分辨率,确定需要关断的开关单元,并将控制开关单元的关断的控制信号发送给相应的开关单元,并且根据该开关状态,发送图像信号给相应的数据线;当确定待显示图像的图像显示模式为动态显示模式时,提供传输该图像的帧频。由此,当待显示图像的图像显示模式为静态显示模式时,通过开关单元的关断,使显示面板中的显示分辨率从低变为高,从而提高待显示图像静态显示时的分辨率,提高用户的体验感;当确定待显示图像的图像显示模式为动态显示模式时,提高传输待显示图像的帧频,以提高显示面板在显示视频等动态图像时的流畅度。因此,该显示面板可以自动判断待显示图像的图像显示模式,自动降低待显示图像的分辨率,或者自动提高传输图像的帧频,从而实现根据待显示图像的图像显示模式,提高静态显示模式下的图像的分辨率,或者提高动态显示模式下的图像的流畅度,从而提高用户的体验感。
图4为根据本公开的实施例的显示面板的驱动方法,该方法包括:
S401、确定从信号源发送的待显示图像的分辨率;
S402、确定待显示图像的分辨率所对应的显示模式;以及
S403、根据显示模式,确定需要导通和关断的开关单元,并控制每一开关单元导通或关断,以及控制每一数据线是否输出图像信号。
在步骤S401中,可以根据接收到的从信号源发送的待显示图像的图像信息,计算出该图像的分辨率,从而确定从信号源发送的待显示图像的分辨率。
在步骤S402中,显示模式可以为超高清显示模式、全高清显示模式或高清显示模式。
在本公开实施例中,超高清显示模式所对应的分辨率可以为2160*3840,其中,3840为行像素个数,2160为列像素个数;全高清显示模式所对应的分辨率可以为1080*1920,其中,1920为行像素个数,1080为列像素个数;高清显示模式所对应的分辨率可以为720*1280,其中,1280为行像素格式,720为列像素个数。
另外,在步骤S402中,
当待显示图像的分辨率大于或等于显示面板的最大分辨率时,确定该待显示图像的分辨率所对应的显示模式为超高清显示模式;
当待显示图像的分辨率小于显示面板的最大分辨率,且大于或等于显示面板的最大分辨率的一半时,确定该待显示图像的分辨率所对应的显示模式为全高清显示模式;
当待显示图像的分辨率小于显示面板的最大分辨率的一半,且大于或等于显示面板的最大分辨率的三分之一时,确定该待显示图像的分辨率所对应的显示模式为高清显示模式。
在本公开实施例中,显示面板可以为超高清的显示面板。例如,该显示面板的分辨率可以为2160*3840,其中,3840为行像素个数,2160为列像素个数。在这样的情况下,显示面板的最大分辨率为2160*3840;最大分辨率的一半的分辨率为1080*1920,其中,1920为行像素个数,1080为列像素个数;最大分辨率的三分之一的分辨率为720*1280,其中,1280为行像素个数,720为列像素个数。
当然,针对例如显示面板的最大分辨率为1080*1920的全高清显示面板, 本公开实施例中的显示面板的结构和驱动方法也同样适用。本公开实施例中的显示面板可以为超高清显示面板,也可以为全高清显示面板,本公开不做限定。
在确定该待显示图像的分辨率所对应的显示模式为超高清显示模式之后,该方法还包括:
当接收到用于更换显示模式为全高清显示模式的用户指示消息时,确定该待显示图像的分辨率所对应的显示模式为全高清显示模式;
当接收到用于更换显示模式为高清显示模式的用户指示消息时,确定该待显示图像的分辨率所对应的显示模式为高清显示模式。
在确定该待显示图像的分辨率所对应的显示模式为全高清显示模式之后,该方法还包括:
当接收到用于更换显示模式为高清显示模式的用户指示消息时,确定该待显示图像的分辨率所对应的显示模式为高清显示模式。
用于更换显示模式为全高清显示模式的用户指示消息可以通过在显示面板中的弹出界面的形式提供给用户以便进行选择,且该指示消息可以在显示过程中由用户选择,也可以在显示面板显示待显示图像之前由用户选择。本公开对提示消息的形式以及时间不做限定。
可以根据实际需要,在显示时降低待显示图像的分辨率。例如,当待显示图像为动态视频时,可以适当降低待显示图像的分辨率,从而降低显示面板的显示功耗。若待显示图像的分辨率为2160*3840,则可以通过驱动IC或者应用处理器,按照算法将该分辨率降低到1080*1920,或者720*1280,然后通过驱动IC发送的控制信号或者通过Gate IC发送的用于控制开关单元导通或者关断的控制信号,降低显示面板的显示分辨率,并降低显示该动态视频的显示功耗。
步骤S403可以包括:
当显示模式为超高清显示模式时,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线;
当显示模式为全高清显示模式时,控制奇数行的开关单元导通,并控制偶数行的开关单元关断,以及将待显示图像的图像信号发送给奇数行的数据线;或者,控制奇数行的开关单元关断,并控制偶数行的开关单元导通,以 及将待显示图像的图像信号发送给偶数行的数据线;
当显示模式为高清显示模式时,控制每组开关单元中第一个和第二个开关单元导通,并控制每组开关单元中的第三个开关单元关断,以及将待显示图像的图像信号发送给每组数据线中的第一根、第五根和第九根的数据线,其中,每组开关单元包括每列相邻的三个开关单元,不同组包括的开关单元可以不同,每组数据线包括每相邻的九根数据线,且不同组包括的数据线可以不同。
其中,当开关单元为N型薄膜晶体管时,控制开关单元导通的信号为高电平,控制开关单元关断的信号为低电平;
当开关单元为P型薄膜晶体管时,控制开关单元导通的信号为低电平,控制开关单元关断的信号为高电平。
下面结合图5和图6更加详细地说明该方法。
图6示出根据本公开的实施例的显示面板的结构。在图6中,K代表开关单元,S代表数据线。例如,K1代表显示面板从上向下排列的第一个开关单元,S1代表显示面板从左到右排列的数据线的第一个数据线。该显示面板以超高清显示面板为例,其中,行像素个数为3840个,列像素格式为6480个。在图6中,由数据线与栅线交叉设置的区域中包括的方块代表亚像素单元。

在步骤S502中,确定该待显示图像的分辨率所对应的显示模式。
在步骤S503中,当显示模式为超高清显示模式时,判断是否接收到用户发送的更换显示模式为全高清显示模式的用户指示消息;若是,则执行步骤S504,否则执行步骤S505。
在步骤S504中,控制奇数行的开关单元导通,并控制偶数行的开关单元关断,以及将待显示图像的图像信号发送给奇数行的数据线;或者,控制奇数行的开关单元关断,并控制偶数行的开关单元导通,以及将待显示图像的图像信号发送给偶数行的数据线。
其中,参见图6所示,通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均导通的控制信号,并输出控制K2、 K4、K6…K3836、K3838、K3840均关断的控制信号,同时将待显示图像的图像信号发送给栅线S1、S3、S5…S6475、S6477、S6479;或者,通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均关断的控制信号,并输出控制K2、K4、K6…K3836、K3838、K3840均导通的控制信号,同时将待显示图像的图像信号发送给栅线S2、S4、S6…S6476、S6478、S6480。
在步骤S505中,判断是否接收到用户发送的更换显示模式为高清显示模式的用户指示消息;若是,则执行步骤S506,否则执行步骤S507。
在步骤S506中,控制每组开关单元中的第一个和第二个开关单元导通,并控制每组开关单元中的第三个开关单元关断,以及将待显示图像的图像信号发送给每组数据线中的第一根、第五根和第九根的数据线;
其中,每组开关单元包括每列相邻的三个开关单元,不同组包括的开关单元可以不同,每组数据线包括每相邻的九根数据线,且不同组包括的数据线可以不同。
需要说明的是,将相邻九根数据线构成一组数据线,是为了最终保留的数据线为完整的RGB结构,以及输出信号端与满足超高清显示模式(UHD)、全高清显示模式(FHD)、高清显示模式(HD)三种分辨率的横纵分辨率之比。
参见图6所示,通过控制驱动控制模块的第一输出端来输出控制K1、K2、K4、K5…K3835、K3836、K3839、K3840均导通的控制信号,并输出控制K3、K6、K9…K3831、K3834、K3837均关断的控制信号,同时将待显示图像的图像信号发送给栅线S1、S5、S9…S6472、S6476、S6480。
在步骤S507中,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线。
参见图6所示,通过控制驱动控制模块的第一输出端来输出控制K1、K2、K3、K4…K3837、K3838、K3839、K3840均关断的控制信号,同时将待显示图像的图像信号发送给每一栅线。
在步骤S508中,当显示模式为全高清显示模式时,判断是否接收到用户发送的更换显示模式为高清显示模式的用户指示消息;若是,则执行步骤S506,否则执行步骤S504。
在步骤S509中,当显示模式为高清显示模式时,控制每组开关单元中的第一个和第二个开关单元导通,并控制每组开关单元中的第三个开关单元关断,以及将待显示图像的图像信号发送给每组数据线中的第一根、第五根和第九根的数据线;
其中,导通的情况与步骤S506相同。
综上,当待显示图像的显示模式为超高清显示模式时,可以根据需要将该图像的显示模式降低为全高清显示模式或者高清显示模式,并通过开关单元的导通来实现降低显示面板的显示分辨率,从而降低待显示图像在显示面板中的显示分辨率,同时降低显示面板的显示功耗;当待显示图像的显示模式为全高清显示模式时,可以根据需要将该图像的显示模式降低为高清显示模式,并通过开关单元的导通来降低显示面板的显示分辨率,从而降低待显示图像在显示面板中的显示分辨率,同时降低显示面板的显示功耗。
参见图7,该显示面板的驱动方法还包括:
S701、接收信号源发送的待显示图像的电压信号;
S702、根据相邻两帧的待显示图像的电压信号,确定当前的图像显示模式,其中图像显示模式为静态显示模式或动态显示模式;
S703、当图像显示模式为静态显示模式时,根据该待显示图像的分辨率,确定需要关断的开关单元,并控制每一开关单元导通或关断,以及根据开关单元的开关状态,输出图像信号给相应的数据线;以及
S704、当图像显示模式为动态显示模式时,提高传输图像的帧频。
在该实施例中,相邻两帧可以是准备传输待显示图像的电压信号时的这一帧和该帧的前一帧。
根据相邻两帧的待显示图像的电压信号,确定当前的图像显示模式,可以包括:
当待显示图像的电压信号与前一帧已显示图像的电压信号相同时,确定当前的图像显示模式为静态显示模式;
当待显示图像的电压信号与前一帧已显示图像的电压信号不同时,确定当前的图像显示模式为动态显示模式。
需要说明的是,在判断图像显示模式的时候,也可以根据待显示图像的电压信号与前一帧或前两帧或前多个帧的已显示图像的电压信号进行比较。 也就是说,本公开不限于只与前一帧传输的电压信号进行比较。
另外,步骤S703可以包括:
当图像显示模式为静态显示模式,并且待显示图像的分辨率小于显示面板的最大分辨率,且大于或等于显示面板的最大分辨率的一半时,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线;
当图像显示模式为静态显示模式,并且待显示图像的分辨率小于显示面板的最大分辨率的一半,且大于或等于显示面板的最大分辨率的三分之一时,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线;或者,控制奇数行的开关单元导通,并控制偶数行的开关单元关断,以及将待显示图像的图像信号发送给奇数行的数据线;或者,控制奇数行的开关单元关断,并控制偶数行的开关单元导通,以及将待显示图像的图像信号发送给偶数行的数据线。
例如,当确定待显示图像的显示显示模式为静态显示模式时,为了提高用户的体验感,可以将待显示图像的分辨率升高到全高清显示模式对应的分辨率,或者升高到超高清显示模式对应的分辨率。例如,若待显示图像的分辨率为720*1280,则可以通过算法将该待显示图像的分辨率升高到1080*1920或者2160*3840。
参见图6所示的显示面板,通过控制开关单元的导通或关断,来提高待显示图像的分辨率。例如,当待显示图像的分辨率为720*1280时,为了将待显示图像的分辨率升高到1080*1920,可以通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均导通的控制信号,并输出控制K2、K4、K6…K3836、K3838、K3840均关断的控制信号,同时,将待显示图像的图像信号发送给栅线S1、S3、S5…S6475、S6477、S6479;或者,通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均关断的控制信号,并输出控制K2、K4、K6…K3836、K3838、K3840均导通的控制信号,同时,将待显示图像的图像信号发送给栅线S2、S4、S6…S6476、S6478、S6480。
又例如,为了将待显示图像的分辨率升高到2160*3840,可以通过控制驱动控制模块的第一输出端来输出控制K1、K2、K3、K4…K3837、K3838、K3839、K3840均关断的控制信号,同时,将待显示图像的图像信号发送给 每一栅线。
通过该驱动方法,根据待显示图像的电压信号,判断该待显示图像的图像显示模式。从而,当确定待显示图像的图像显示模式为静态显示模式时,根据该图像的分辨率,确定需要关断的开关单元,并发送控制开关单元的关断的控制信号给相应的开关单元,同时根据该开关状态,发送图像信号给相应的数据线,使得当待显示图像的图像显示模式为静态显示模式时,通过开关单元的关断,使显示面板中的显示分辨率从低变为高,由此提高待显示图像静态显示时的分辨率,提高用户的体验感。该驱动方法还包括,当确定待显示图像的图像显示模式为动态显示模式时,提高传输待显示图像的帧频,从而提高显示面板在显示视频等动态图像时的流畅度。因此,通过自动判断待显示图像的图像显示模式,自动降低待显示图像的分辨率,或者自动提高传输图像的帧频,从而实现根据待显示图像的图像显示模式,提高静态显示模式下的图像的分辨率,或者提高动态显示模式下的图像的流畅度,由此提高用户的体验感。

S803、当图像显示模式为静态显示模式时,根据该待显示图像的分辨率,确定需要关断的开关单元,并控制每一开关单元导通或关断,以及根据开关单元的开关状态,输出图像信号给相应的数据线。
在该实施例中,相邻两帧可以是准备传输待显示图像的电压信号时的这一帧和该帧的前一帧。
根据相邻两帧的待显示图像的电压信号,确定当前的图像显示模式,可以包括:
当待显示图像的电压信号与前一帧已显示图像的电压信号相同时,确定当前的图像显示模式为静态显示模式;
当待显示图像的电压信号与前一帧已显示图像的电压信号不同时,确定当前的图像显示模式为动态显示模式。
需要说明的是,在判断图像显示模式的时候,也可以根据待显示图像的电压信号与前一帧或前两帧或前多个帧的已显示图像的电压信号进行比较。也就是说,本公开不限于只与前一帧传输的电压信号进行比较。
在本公开的实施例中,静态显示模式可以是显示屏处于阅读或者静态图片等不会变化的情况下的图像,动态显示模式可以是显示屏处于动态图片或者视频等一直变化的情况下的图像。
另外,步骤S803可以包括:
当图像显示模式为静态显示模式,并且待显示图像的分辨率小于显示面板的最大分辨率,且大于或等于显示面板的最大分辨率的一半时,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线;
当图像显示模式为静态显示模式,并且待显示图像的分辨率小于显示面板的最大分辨率的一半,且大于或等于显示面板的最大分辨率的三分之一时,控制每一开关单元关断,以及将待显示图像的图像信号发送给每一数据线;或者,控制奇数行的开关单元导通,并控制偶数行的开关单元关断,以及将待显示图像的图像信号发送给奇数行的数据线;或者,控制奇数行的开关单元关断,并控制偶数行的开关单元导通,以及将待显示图像的图像信号发送给偶数行的数据线。
例如,当确定待显示图像的显示显示模式为静态显示模式时,为了提高用户的体验感,可以将待显示图像的分辨率升高到全高清显示模式对应的分辨率,或者升高到超高清显示模式对应的分辨率。例如,若待显示图像的分辨率为720*1280,则可以通过算法将该待显示图像的分辨率升高到1080*1920或者2160*3840。
参见图6所示的显示面板,通过控制开关单元的导通或关断,来提高待显示图像的分辨率。例如,当待显示图像的分辨率为720*1280时,为了将待显示图像的分辨率升高到1080*1920,可以通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均导通的控制信号,并输出控制K2、K4、K6…K3836、K3838、K3840均关断的控制信号,同时,将待显示图像的图像信号发送给栅线S1、S3、S5…S6475、S6477、S6479;或者,通过控制驱动控制模块的第一输出端来输出控制K1、K3、K5…K3835、K3837、K3839均关断的控制信号,并输出控制K2、K4、K6…K3836、K3838、 K3840均导通的控制信号,同时,将待显示图像的图像信号发送给栅线S2、S4、S6…S6476、S6478、S6480。
又例如,为了将待显示图像的分辨率升高到2160*3840,可以通过控制驱动控制模块的第一输出端来输出控制K1、K2、K3、K4…K3837、K3838、K3839、K3840均关断的控制信号,同时,将待显示图像的图像信号发送给每一栅线。
该方法还可以包括,当图像显示模式为动态显示模式时,提高传输图像的帧频。
通过该驱动方法,根据待显示图像的电压信号,判断该待显示图像的图像显示模式。从而,当确定待显示图像的图像显示模式为静态显示模式时,根据该图像的分辨率,确定需要关断的开关单元,并发送控制开关单元的关断的控制信号给相应的开关单元,同时根据该开关状态,发送图像信号给相应的数据线,使得当待显示图像的图像显示模式为静态显示模式时,通过开关单元的关断,使显示面板中的显示分辨率从低变为高,由此提高待显示图像静态显示时的分辨率,提高用户的体验感。该驱动方法还包括,当确定待显示图像的图像显示模式为动态显示模式时,提高传输待显示图像的帧频,从而提高显示面板在显示视频等动态图像时的流畅度。因此,通过自动判断待显示图像的图像显示模式,自动降低待显示图像的分辨率,或者自动提高传输图像的帧频,从而实现根据待显示图像的图像显示模式,提高静态显示模式下的图像的分辨率,或者提高动态显示模式下的图像的流畅度,由此提高用户的体验感。

S902、DIC将收到的显示图像的电压信号存储在DIC中的RAM区,并向手机显示屏发送该显示图像信息;
S903、手机显示屏显示该图像;
S904、手机平台再次发送待显示图像给DIC;
S905、DIC将接收到的待显示图像的电压信号与DIC中的RAM区存储的电压信号进行比较;若相同,则执行步骤S906;否则,执行步骤S907;
S906、确定该待显示图像的图像显示模式为静态显示模式,根据该图像的分辨率,确定需要关断的开关单元,并控制每一开关单元导通或关断,以及根据开关单元的开关状态,输出图像信号给相应的数据线;
其中,当确定待显示图像的图像显示模式为静态显示模式时,手机平台将不用再向DIC发送图像,因为DIC中的RAM已经存储了该图像的信息,从而节省静态显示模式下的显示功耗;
S907、确定该待显示图像的图像显示模式为动态显示模式,并提高传输图像的帧频;
其中,当确定待显示图像的图像显示模式为动态显示模式时,手机平台将继续将待显示图像发送给DIC,通过提高传输图像的帧频,提高动态显示图像的流畅度,并提高用户的体验感。
