在实际应用中,In-cell触控显示屏的图像显示效果与In-cell触控显示面屏的报点率相关,若报点率较低,当用户在In-cell触控显示面屏上快速划动时,会出现拖尾、断线等问题。然而,In-cell触控显示屏的报点率是固定的,跟随刷新率,其中,刷新率是指In-cell触控显示屏对其所显示图像进行刷新的频率。因此,只能通过调整刷新率来调整报点率,来提升In-cell触控显示屏的图像显示效果。然而,要实现刷新率的调整,需要In-cell触控显示屏支持变频功能,成本较高。
本申请实施例提供的显示设备、图像处理方法及装置,旨在解决相关技术的如上技术问题。

在一些实施例中,触控芯片702根据该刷新率,确定目标报点率,并将触控显示屏的当前报点率更新为该报点率,并按照该报点率上报触控操作对应的触控数据。
具体的,当用户在触控显示屏201上进行触控操作时,触控芯片702会获取触控操作对应的触控点坐标,并基于当前报点率上报触控点坐标给处理器254,相应的,处理器254在接收到触控点的坐标后,根据触控点坐标,确定触控显示屏201的目标刷新率,并将目标刷新率发送给时序控制器704。
相应的,时序控制器704根据目标刷新率,确定目标报点率,并将触控显示屏201的当前报点率更新为目标报点率,在后续的触控操作中,触控显示屏201按照目标报点率上报触控数据。
下面结合具体的实施例进行说明:
图8为本申请一实施例提供的一种图像处理方法的流程示意图。如图8所示,显示设备200中的各器件被配置为执行以下步骤:
在S801中,触控芯片响应于用户作用在触控显示屏上的触控操作,获取触控操作对应的触控信号,并发送给主控芯片;
在实际应用中,触控芯片702位于触控显示屏201上,当用户在触控显示屏201上进行触控操作时,触控芯片702会获取用户的触控操作对应的触控点坐标。
具体的,触控芯片702感应触控信号,将触控信号由模拟信号转换为数字信号,从而获得触控点坐标。
需要说明的是,对于需要获取坐标的触控点数量以及触控点位置,本申请实施例也不做具体限定,示例性的,可以获取触控操作中前两个触控点的坐标,也可以获取触控操作中所有触控点的坐标。
在S802中,主控芯片获取触控信号中携带的触控点坐标,以及,基于当前报点率上报触控点坐标给处理器。
在S803中,处理器根据触控点坐标,确定触控显示屏的目标刷新率,将目标刷新率发送给时序控制器和触控芯片。
可以理解的是,触控显示屏的报点率与刷新率相关,若报点率较低,当用户在触控显示屏201上快速划动时,会出现拖尾、断线等问题。本实施方式中,可以根据触控点的坐标确定触控显示屏201当前的报点率是否满足要求,示例性的,可以根据触控点的坐标确定各触控点之间的距离,确定报点率的大小,例如,触控点间的距离越大,则报点率越低,触控点间的距离越大,则报点率越高,至于根据触控点的坐标确定目标刷新率的实施方式,在后续实施例中示出。
在S804中,时序控制器被配置为根据目标刷新率,控制触控显示屏对显示的内容进行刷新。
在S805中,根据目标刷新率,确定目标报点率,并将触控显示屏的当前报点率更新为目标报点率。
本申请实施例提供的显示设备,触控芯片响应于用户作用在触控显示屏上的触控操作,获取触控操作对应的触控点坐标,处理器根据触控点坐标,确定触控显示屏的目标刷新率;时序控制器根据目标刷新率,控制触控显示屏对显示的内容进行刷新;触控芯片根据目标刷新率,确定目标报点率,并将触控显示屏的当前报点率更新为目标报点率。本实施方式中,通过用户的触控操作中,触控点之间的坐标关系来调整刷新率,不需要In-cell触控显示屏支持变频功能,即可调整显示屏的报点率,可低成本实现对In-cell触控显示屏的图像显示效果的提升,提升触控体验。
图9为本申请另一实施例提供的一种图像处理方法的流程示意图。如图9所示,显示设备200中的处理器254具体被配置为执行以下步骤:
在S901中,接收主控芯片发送的触控信号中携带的触控点坐标。
至于触控芯片获取触控操作对应的触控信号的实施方式,请参考上述图8中所示的实施例,此处不再赘述。
在S902中,根据触控点坐标,确定相邻触控点之间的距离。
在S903中,若距离大于触控显示屏的当前刷新率对应的预设距离,则根据距离、预设距离和当前刷新率,确定触控显示屏的目标刷新率。
应理解,对于根据触控点坐标,确定相邻触控点之间的距离的实施方式可以参考现有技术,此处不再赘述。
需要说明的是,本申请实施例对于相邻触控点的数量也不做具体限定,示例性的,可以包括如下两种方式:
方式一、对于同一触控操作,若该触控操作的速度较快,为了避免该触控操作出现拖尾、断线的问题,可以只获取该触控操作的前几个触控点,从而根据前几个触控点之间的距离,来进行后续的目标刷新率确定,从而调整该触控操作中后续的触控点的报点率,从而提升该触控操作对应的显示效果。
方式二、可以确定触控点中所有相邻触控点间的距离,确定该触控操作中多个相邻触控点距离的平均值为上述相邻触控点之间的距离。
需要说明的是,上述两个方式的区别在于:
方式一是根据当前触控操作的前几个触控点调整后续触控点对应的刷新率,可以实时的对当前的触控操作进行调整。示例性的,以获取当前触控操作的前两个触控点为例,根据该两个触控点的距离,确定触控显示屏的目标刷新率,再通过该目标刷新率,处理该触控操作中后续的触控点。
方式二是根据当前的触控操作的所有点来调节触控显示屏的刷新率,也即调整后的刷新率用于对后续的其他触控操作进行处理,而对当前的触控操作无影响。示例性的,当用户在触控显示屏上进行第一次触控操作后,根据第一次触控操作中触控点的距离,来调整触控显示屏的刷新率,当用户进行第二次触控操作时,根据调整后的刷新率对第二次触控操作进行处理。
通过上述两种方式,均可以实时的调整当前的触控操作,从而实时的提升触控显示屏的图像显示效果。
为了方便理解,下面以方式一为例,对本实施例中的步骤S903进行具体说明,其中,在S903中,具体包括如下步骤S9031~S9033:
在S9031中,获取触控显示屏的帧刷新率。
具体的,可以根据触控显示屏的刷新行数的最小值、预设距离以及最大帧间距离,确定触控显示屏的帧刷新率。其中,预设距离为触控显示屏当前的刷新率对应的距离最小值,最大帧间距离为该触控显示屏的最大触控点距离。
在实际应用中,当前刷新行数为触摸显示屏的显示区域的刷新行数与blank区域的刷新行数之和,以触控显示屏的显示区域的刷新行数为2160行,blank区域的刷新行数为106~4639行为例,该触控显示屏的刷新行数的范围为:2266~6799行,该触控显示屏对应的刷新率的范围为:40HZ~120HZ,该触控显示屏的刷新行数最小值为2266。
一种可行的实施例中,由于blank区域对应的刷新行数是可变值,而刷新行数与刷新率相关,因此,可以通过调整blank区域对应的刷新行数来调整刷新率,具体的,可以先根据如下公式1确定帧刷新率:
V=D min/[(L max-L min)/L min] (公式1)
其中,V为帧刷新率,D min为最小刷新率对应的刷新行数,L max为该触控显示屏的最大触控点距离,L min为该触控显示屏当前刷新率对应的预设距离。
进一步的,根据触控显示屏当前的刷新率和帧刷新率确定目标刷新率,具体请参见步骤S9032:
在S9032中,根据距离、预设距离、当前刷新行数和帧刷新率,确定触控显示屏的目标刷新行数。
在实际应用中,不同刷新率对应的预设距离不同,可以根据实际需求设置预设距离,示例性的,以预设距离为240mm,最大触控点距离为720mm,触控显示屏的刷新行数的最小值为2266为例,根据如上公式可以得出,该触控显示屏的帧刷新率为1133。
需要说明的是,其他刷新率对应的帧刷新率的计算方法可参考上述,此处不再赘述。
具体的,可以根据如下公式2确定触控显示屏的目标刷新行数:
Figure PCTCN2022081763-appb-000001
其中,D 目标为触控显示屏的目标刷新行数,D 当前为触控显示屏当前的刷新行数,L 当前为触控点距离,L min为当前刷新率对应的预设距离,V为帧刷新率。
示例性的,以触控显示屏的刷新率为60HZ为例,根据现有技术可知,其对应的刷新行数为4533行,则根据上述公式2可以得出如下公式3:
Figure PCTCN2022081763-appb-000002
在S9033中,根据目标刷新行数,确定触控显示屏的目标刷新率。
具体的,可以根据目标刷新行数、触控显示屏的时钟周期及触控显示屏的刷新列数,确定触控显示屏的目标刷新率。
示例性的,可以根据如下公式4确定触控显示屏的目标刷新率:
Figure PCTCN2022081763-appb-000003
其中,F 目标为触控显示屏的目标刷新率,Fclk为触控显示屏的时钟周期,H t为触控显示屏的刷新列数。
图10为本申请一实施例提供的图像处理装置的结构示意图。该图像处理装置应用于显示设备,该显示设备包括触控显示屏。如图10所示,本实施例提供的图像处理装置1000可以包括:
第一获取模块1001,用于响应于用户作用在触控显示屏上的触控操作,获取触控操作对应的触控点坐标;
第一确定模块1002,用于根据触控点坐标,确定触控显示屏的目标刷新率;
第一处理模块1003,用于根据目标刷新率,控制触控显示屏对显示的内容进行刷新,根据目标刷新率,确定目标报点率,并将触控显示屏的当前报点率更新为目标报点率。
在一些实施例中,第一确定模块1002具体用于:根据触控点坐标,确定相邻触控点之间的距离;
若距离大于触控显示屏的当前刷新率对应的预设距离,则根据距离、预设距离和当前刷新率,确定触控显示屏的目标刷新率。
在一些实施例中,第一获取模块1001具体用于:获取触控显示屏的帧刷新率;
第一确定模块1002具体用于:根据距离、预设距离、当前刷新行数和帧刷新率,确定触控显示屏的目标刷新行数;
根据目标刷新行数,确定触控显示屏的目标刷新率。
在一些实施例中,第一获取模块1001具体用于:根据触控显示屏的刷新行数的最小值、预设距离以及最大帧间距离,确定触控显示屏的帧刷新率。
在一些实施例中,第一确定模块1002具体用于:根据目标刷新行数、触控显示屏的时钟周期及触控显示屏的刷新列数,确定触控显示屏的目标刷新率。
需要说明的是,本实施例提供的装置可用于执行上述的图像处理方法,其实现方式和技术效果类似,本实施例此处不再赘述。
为了保障触控体验的同时,降低显示设备的功耗,本申请实施例还提供了一种报点率确定方法。下面将采用详细的实施例,对本申请实施例提供的报点率确定方法进行说明。
首先对本申请涉及的应用场景进行解释说明:
图11为本申请一实施例提供的报点率确定方法中对显示设备进行触控操作的场景示意图。如图11所示,该场景包括显示设备200,其中,显示设备200包括触控显示屏201、触控芯片702以及处理器254。
一些实施例中,本申请实施例对于触控显示屏201的类型也不做具体限定,例如,其可以是液晶显示屏、OLED显示屏等。
在实际应用中,用户可以通过手指或者触控笔在触控显示屏201上进行触控操作,由触控芯片702采集触控操作对应的触控信号,再按照该显示设备200当前的报点率,将触控信号对应的报点信息上报给处理器254,从而在触控显示屏201上显示相应画面。
发明人在使用显示设备的过程中发现:目前的触控显示屏大多采用固定报点率,且为了保障触控体验,其设置的报点率相对较高,但较高的报点率会导致触控显示屏的功耗较高,进而导致显示设备的功耗较高。然而,当触控显示屏仅实现显示功能未进行触控操作时,若仍以高报点率运行会带来极大的功耗浪费,但若以低报点率运行,在用户进行触控操作时又无法保证触控体验。
有鉴于此,本申请实施例提供一种显示设备、报点率确定方法及装置,旨在解决相关技术的如上技术问题,本申请主要构思为:在触控显示屏仅显示且未进行触控操作时,采用较低的报点率运行,当用户对触控显示屏进行触控操作时,根据用户的触控操作实时的调整显示设备的报点率,从而实现在保障触控体验的同时,降低触控显示屏的功耗。
下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
图12为本申请一实施例提供的报点率确定方法的流程示意图。其中,该报点率确定方法应用于如上任一实施例提供的显示设备200,如图12所示,在本申请实施例中,显示设备200中的上述各器件被配置为执行以下步骤:
在S1201中,触控芯片响应于用户作用在触控显示屏上的触控操作,获取触控操作对应的报点信息。
在实际应用中,触控芯片702位于触控显示屏201上,用于实时检测用户在触控显示屏201上的触控操作,当检测到用户在触控显示屏201上进行触控操作时,触控芯片702会实时采集触控操作对应的报点信息。
具体的,触控芯片702检测触控信号后,将触控信号由模拟信号转换为数字信号,从而获得报点信息。
在S1202中,触控芯片按照当前报点率将报点信息上报至处理器。
需要说明的是,对于当前报点率的大小本申请实施例不做具体限定,例如,在显示设备200启动时,当仅用于显示功能(用户未对其进行触控操作时),当前报点率可以为该显示设备200的最低报点率,当用户对显示设备进行触控操作时,当前报点率可以为大于最低报点率的任意值。
在S1203中,根据触控芯片的连续报点次数,确定目标报点率。
需要说明的是,在同一报点率的场景下,每个触控操作对应的报点信息是连续的,且每个触控操作对应的连续报点次数与触控操作的类型相关,示例性的,触控操作的作用时间越长,其对应的连续报点次数越多,因此,可以根据触控操作对应的连续报点次数确定目标报点率。
一些实施例中,触控操作的连续报点次数与目标报点率可以为一一对应关系(每个连续报点次数对应一个报点率)或者也可以为一对多的对应关系(多个连续报点次数对应于一个报点率),具体的,可以预先设定连续报点次数与目标报点率的对应关系,再根据连续报点次数与目标报点率的关系,确定该连续报点次数对应的目标报点率。
另一些实施例中,可以预先设定次数阈值和至少两个大小不同的报点率,当确定当前触控操作对应的连续报点次数大于次数阈值时,以较高的报点率进行上报,当确定当前触 控操作对应的连续报点次数小于次数阈值时,以较低的报点率进行上报,至于具体的目标报点率的确定方法,在后续实施例中详细说明,此处不再赘述。
本实施方式中,根据触控操作对应的连续报点次数确定不同的触控操作对应的报点率,可以更精细化调节触控显示屏的报点率,提升障触控体验。
在S1204中,将当前报点率替换为目标报点率。
具体的,在确定目标报点率之后,发送控制信号至触控芯片702,以将其当前的报点率替换为目标报点率。
本申请提供的报点率确定方法,触控芯片702响应于用户作用在触控显示屏201上的触控操作,获取触控操作对应的报点信息,并按照当前报点率将报点信息上报至处理器254;处理器根据触控芯片702的连续报点次数,确定目标报点率,并将当前报点率替换为目标报点率。通过本申请提供的实施方式,可以根据用户的触控操作对应的连续报点次数,实时的调整显示设备的报点率,从而在保障触控体验的同时,降低显示设备的功耗。
图13为本申请另一实施例提供的一种报点率确定方法的流程示意图。在图12所示实施例的基础上,本实施例对上述处理器254执行的步骤进行更详细的描述,如图13所示,显示设备200中的处理器254具体被配置为执行以下步骤:
在S1301中,接收报点信息。
在S1302中,根据报点信息确定连续报点次数。
其中,连续报点次数用于表示连续接收到报点信息的次数。应理解,步骤S1301~S1302与图12所示实施例中的步骤S1203类似,此处不再赘述。
在S1303中,判断连续报点次数是否大于报点次数阈值。
在S1304中,若连续报点次数大于报点次数阈值,则确定目标报点率为大于或等于当前报点率的第一报点率。
在S1305中,若连续报点次数小于或等于报点次数阈值,则确定目标报点率为小于或等于当前报点率的第二报点率。
一些实施例中,若连续报点次数大于报点次数阈值时,说明用户对触控显示屏201进行了触控操作,且需要以较大的报点率上报后续的触控操作对应的报点信息。
具体的,一方面,若在此次触控操作前已经有其他触控操作,并已经将触控显示屏201的报点率替换为了第一报点率,即当前报点率等于第一报点率,此时不需要对当前的报点率进行调整,也即确定目标报点率为当前报点率;另一方面,若当前触控显示屏201仅最为显示功能,即当前报点率小于第一报点率,此时需要将当前报点率调节为较大的第一报点率,即确定目标报点率为第一报点率。
另一些实施例中,若连续报点次数小于或等于报点次数阈值时,则以较小的报点率运行即可满足当前触控操作的触控体验,因此,需要以较低的报点率上报后续触控操作对应的报点信息。
具体的,一方面,若在此次触控操作前已经将触控显示屏的报点率替换为了第二报点率,即当前报点率为第二报点率,此时不需要对当前的报点率进行调整,即确定目标报点率为当前报点率;另一方面,若当前报点率大于第二报点率,此时需要将当前报点率调节为更小的第二报点率。
需要说明的是,对于第一报点率和第二报点率的大小,本申请实施例不做具体限定,示例性的,第一报点率的值大于第二报点率。
本实施方式中,通过对连续报点次数与阈值之间的大小判断来确定目标报点率,可以在用户进行触控操作时,及时调整触控显示屏的报点率,从而在保障触控体验的同时,降低显示设备的功耗。
需要说明的是,在步骤S1303、判断连续报点次数是否大于报点次数阈值之前,还需要确定报点次数阈值的大小。
对于报点次数阈值的大小,本申请实施例不做具体限定,一些实施例中,每个显示设 备200的报点次数阈值可以为一固定值。具体的,包括:若当前的触控操作对应的连续报点次数大于报点次数阈值,则以较高的报点率(第一报点率)上报触控操作对应的报点信息,若当前的触控操作对应的连续报点次数小于或等于报点次数阈值,则以较低的报点率(第二报点率)上报触控操作对应的报点信息,从而实现根据报点次数实时调节触控显示屏的报点率,以降低功耗。
在另一些实施例中,由于不同触控类型的触控操作对应的连续报点次数不同,其需要的报点率也不同,其中,触控类型可以包括:点击操作、滑动操作、长按操作等,例如点击操作,其对应的报点次数较少,滑动操作和长按操作对应的连续报点次数相对较多。
因此,本步骤中,还可以根据触控操作的类型,确定触控操作对应的报点率,下面结合如下两个步骤进行说明:
(1)确定连续报点次数所属的范围。
(2)根据连续报点次数所属的范围,确定与连续报点次数进行比较的报点次数阈值。
在实际应用中,不同的触控类型所需要的报点率不同,可以预先设定不同触控类型对应的连续报点次数范围,再根据续报点次数所属的范围,确定该触控操作对应的触控类型。
进一步的,根据触控类型与报点次数阈值之间的对应关系,确定该次触控操作对应的报点次数阈值。
本实施方式中,通过设置不同触控类型对应的连续报点次数所属的范围和报点次数阈值,从而可以根据不同触控类型确定当前触控操作对应的报点率,可以精细化的调整触控显示屏的报点率,进一步提升触控体验,降低显示设备的功耗。
在S1306中,将当前报点率替换为目标报点率。
需要说明的是,在将当前报点率替换为目标报点率之后,继续按照当前报点率运行,然而,在运行过程中,用户随时会停止触控操作,若一直按照该报点率运行,当用户长时间不进行触控操作时,仍会导致显示设备的功耗较高。
有鉴于此,本申请实施例中,可以根据未接收到报点信息的持续时长重新调整触控显示屏201的报点率,下面结合步骤S1307~S1310对后续的报点率调节过程进行说明:
在S1307中,确定未接收到报点信息的持续时长。
本步骤中,可以实时记录当前收到报点信息的时刻并计时,从而确定未接收到报点信息的持续时长,此处不再赘述。
在S1308中,根据触控显示屏当前的运行模式,确定运行模式对应的时长阈值。
在实际应用中,触控显示屏201的不同运行模式运行时,用户对触控显示屏201的触控操作也会不同,其中,运行模式可以包括以下至少一种或多种:书写模式、游戏模式、视频播放模式和通话模式等。示例性的,若触控显示屏201当前处于书写模式或者游戏模式,则用户对触控显示屏201的触控操作会相对频繁,也即每两个触控操作之间的时间间隔较短,此时,可以设置较小的时长阈值,以对触控显示屏201的报点率进行更精细的调节。
另外,若触控显示屏201当前处于视频播放模式,则用户对触控显示屏201的触控操作相对较少,也即每两个触控操作之间的时间间隔较长,此时,可以设置较大的时长阈值,以降低处理器254的处理压力。
一些实施例中,可以预先设置运行模式与时长阈值之间的对应关系,再根据对应关系,确定该模式对应的时长阈值,对于运行模式与时长阈值的具体大小,此处不做具体限定。
在S1309中,若持续时长大于时长阈值,则确定目标报点率为小于当前报点率的第三报点率。
需要说明的是,第三报点率的值小于或者等于第二报点率,对于第三报点率的具体大小,本申请实施例不做具体限定。
本步骤中,当持续时长大于时长阈值时,说明用户在时长阈值内未进行触控操作,此时需要将降低当前报点率,以降低触控显示屏的功耗。相应的,若持续时长小于时长阈值 时,说明用户在该运行模式下,持续的对触控显示屏进行触控操作,此时仍以当前的报点率运行,以保障触控体验。
在S1310中,若检测到触控显示屏的运行模式改变,则将时长阈值替换为改变后的运行模式对应的时长阈值。
一些实施例中,需要实时检测触控显示屏201当前的运行模式,并根据当前的运行模式实时的确定其对应的时长阈值,从而进一步提升报点率调节的准确性。
图14为本申请一实施例提供的报点率确定装置的结构示意图。该报点率确定装置应用于显示设备,该显示设备包括触控显示屏。如图14所示,本实施例提供的报点率确定装置1400可以包括:
第二获取模块1401,用于响应于用户作用在触控显示屏上的触控操作,获取触控操作对应的报点信息;
第二确定模块1402,用于根据连续报点信息的报点次数,确定目标报点率;
第二处理模块1403,用于将触控显示屏的当前报点率替换为目标报点率。
在一些实施例中,第二确定模块1402具体用于:接收报点信息;获取包含报点信息的触控芯片的连续报点次数;若连续报点次数大于报点次数阈值,则确定目标报点率为大于或等于当前报点率的第一报点率。
在一些实施例中,第二确定模块1402具体用于:接收报点信息;获取包含报点信息的触控芯片的连续报点次数;若连续报点次数小于或等于报点次数阈值,则确定目标报点率为小于或等于当前报点率的第二报点率。
在一些实施例中,第二确定模块1402还用于:在获取连续报点次数之后,确定连续报点次数所属的范围;根据连续报点次数所属的范围,确定与连续报点次数进行比较的报点次数阈值;其中,不同范围对应的报点次数阈值不同。
在一些实施例中,第二确定模块1402还用于:确定未接收到报点信息的持续时长;若持续时长大于时长阈值,则确定目标报点率为小于当前报点率的第三报点率。
在一些实施例中,第二处理模块1403还用于:若检测到触控显示屏的运行模式改变,则将时长阈值替换为改变后的运行模式对应的时长阈值。
需要说明的是,本实施例提供的报点率确定装置可用于执行上述的报点率确定方法,其实现方式和技术效果类似,本实施例此处不再赘述。
为了在不改变显示面板的硬件设计以及背光驱动方式的前提下,有效改善显示面板亮度不均匀的问题,提高显示效果,本申请实施例还提供了一种显示驱动方法。
图15为本申请实施例中液晶显示器的示意图,如图15所示,液晶显示器包含控制模块1501、显示面板1502、扫描驱动器1503、脉宽调制产生器1504、数据驱动器1505、时序控制器1506及背光模组1507。显示面板1502包括数据线D1至Dn、与数据线D1至Dn交叉的扫描线G1至Gm、以及以矩阵的形式排列在数据线D1至Dn和扫描线G1至Gm的交叉处的多个像素1521,其中,m和n均为正整数。像素1521形成在显示面板1502的下玻璃基板上,每个像素1521包括薄膜晶体管TFT、液晶电容Clc以及存储电容Cst。
时序控制器1506对显示面板1502接收到的包含在输入画面中的数字视频数据RGB重新布置,并且将重新布置的数据视频数据RGB提供给数据驱动器1505。时序控制器1506接收时序信号,例如垂直同步信号Vsycn、水平同步信号Hsync、数据使能信号DE和时钟CLK,并利用时序信号生成用于控制数据驱动器13和栅极驱动器14的操作时序的控制信号。
扫描驱动器1503通过扫描线向像素1521输出扫描驱动信号,以使得每一行的像素中的TFT依序开启,同时,数据驱动器1505通过数据线向像素1521输出对应的数据驱动信号,以使像素1521充电到各自所需的电压,以显示不同的灰阶。当同一行像素充电完毕后,扫描驱动器1503将该行的扫描驱动信号关闭,并向下一行的像素输出扫描驱动信号,再由数据驱动器1505对下一行的像素进行充电。以此类推,直到显示面板1502的所有像 素1521都充电完成,再从第一行开始充电。
数据驱动器1505在时序控制器1506的控制下锁存数字视频数据并将锁存的数字视频数据进行转换,由此,生成正数据电压和负数据电压,然后数据驱动器1505向数据线D1至Dn提供正数据电压和负数据电压。扫描驱动器1503在时序控制器1506的控制下顺序地向扫描线G1至Gm提供具有约一个水平周期(约一帧时间)的宽度扫描脉冲。
脉宽调制产生器1504用于向背光模组1507输出PWM信号,背光模组1507根据PWM信号进行发光。根据PWM信号,背光模组出射的光(即,入射到液晶显示面板的光)以一定频率明暗交替变化,即,在PWM信号中存在高电平和低电平,当PWM信号处于低电平时,背光模组处于暗态,此时,背光模组不发光;当PWM信号处于高电平时,背光模组处于亮态,此时,背光模组发光以向显示面板提供背光。
目前液晶显示屏幕的背光调整通常采用数字调光的方式实现,即采用调整PWM占空比的方式调整,其中,PWM占空比是指一个脉冲周期内高电平的所整个周期占的比例。通过调节PWM占空比来调整液晶显示屏幕中LED背光灯的打开时间,从而达到调整屏幕亮度的效果。
液晶显示面板中的像素包括薄膜晶体管TFT,而TFT包括有源层。当背光模组发射的光照射到有源层时,会影响有源层中载流子的特性,导致有源层的阻抗增大,TFT的漏电流增大,从而导致像素的充电率降低,即存储电容Cst中存储的电荷量降低,致使液晶层中的液晶偏转角度不足,最终导致像素的显示亮度降低。
图16为本申请实施例中像素充电的示意图,如图16所示,像素预设的充电时间为T。在无光照情况下,像素的驱动电压上升至预设值时所需要的时间为t1,像素的充电时间为Ta=T-t1;在有光照情况下,由于有源层的阻抗相对于无光照时增大,TFT的漏电流增大,从而导致驱动电压上升速度变慢,此时,像素的驱动电压上升至预设值时所需要的时间为t2,t2>t1,像素的充电时间为Tb=T-t2。在充电时间T相同的情况下,由于t2>t1,导致在有光照时像素的充电时间Tb小于无光照时的充电时间Ta,即Tb<Ta,从而导致像素充电率降低。
图17为本申请实施例中PWM信号与漏电流的关系示意图,其中Ids表示漏电流,如图17所示,当PWM信号为高电平时,此时背光模组发光,相应的,漏电流Ids也增大,从而影响像素的充电率。
本申请提供的显示装置及其显示驱动方法,旨在解决现有技术的如上技术问题。
本申请的主要构思为:当背光模组在PWM信号的控制下发光时,光照对TFT的影响主要是对显示面板中像素的充电率的影响,因此,本申请基于软件补偿的实现方式,根据PWM信号对显示面板中不同显示区域各自对应的像素的驱动信号进行调整,从而对像素中存储电容的充电率进行调整。在TFT由于光照而导致不同像素的充电率存在差异时,本申请可以通过软件调整的方式来对像素的充电率进行补偿,从而,在不改变显示面板的硬件设计以及背光驱动方式的前提下,可以有效改善显示面板亮度不均匀的问题,提高显示效果。
下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
可以理解,本申请中显示驱动方法的处理步骤可以由显示装置内的控制芯片实现,例如,由时序控制器实现等。
在一些实施例中,提供一种显示装置的显示驱动方法,其中,显示装置包括显示面板和被配置为向显示面板提供背光的背光模组。图18为本申请实施例提供的显示驱动方法的示意图,如图18所示,该方法主要包括以下步骤:
S1801、获取背光模组向显示面板提供背光时的脉冲宽度调制PWM信号;
S1802、根据PWM信号对显示面板中不同显示区域对应像素的驱动信号进行调整,以调整不同显示区域对应像素的存储电容的充电率;其中,不同显示区域包括至少两个亮度 不同的显示区域。
以方法应用于控制芯片为例进行解释说明,当背光模组在PWM信号的控制下发光时,控制芯片获取背光模组向显示面板提供背光时的脉冲宽度调制PWM信号,从而,控制芯片可以根据PWM信号的高低电平信号波形,来对显示面板中不同显示区域内像素的驱动信号进行相应的调整,从而起到调整像素中存储电容的充电率的问题。
例如,对于显示面板上的显示区域,具体可以包括高亮显示区域,对于该区域而言,在受到光照时,会导致该区域像素的充电率降低,从而导致该区域的实际显示亮度低于预设亮度,因此,可以对该区域像素的充电率进行补偿,以保证显示区域亮度的均匀性。
本实施例提供一种显示装置的显示驱动方法,当背光模组在PWM信号的控制下发光时,根据PWM信号对显示面板中不同显示区域各自对应的像素的驱动信号进行调整,从而对像素中存储电容的充电率进行调整。在TFT由于光照而导致不同像素的充电率存在差异时,本实施例可以通过软件调整的方式来对像素的充电率进行补偿,从而,在不改变显示面板的硬件设计以及背光驱动方式的前提下,可以有效改善显示面板亮度不均匀的问题,提高显示效果。
在一些实施例中,不同显示区域包括第一显示区域以及第二显示区域,第一显示区域的亮度高于第二显示区域的亮度。具体的,第一显示区域例如可以是高亮显示区域,第二显示区域例如可以是低亮显示区域。
本实施例中,根据PWM信号对显示面板中不同显示区域对应像素的驱动信号进行调整,以调整不同显示区域对应像素的存储电容的充电率,包括:S18021、根据PWM信号的高低电平信号特征,对显示面板中第一显示区域对应像素的驱动信号进行调整,以增加第一显示区域对应像素的存储电容的充电率。
具体的,对于显示亮度较高的第一显示区域,在受到光照时,会导致该第一显示区域的像素的充电率降低,从而导致该第一显示区域的实际显示亮度低于预设亮度,因此,可以对该区域像素的充电率进行补偿,具体为对该第一显示区域对应像素的驱动信号进行调整以增加第一显示区域对应像素的存储电容的充电率,在充电率增加后,该第一显示区域的显示亮度相应增加,从而保证显示区域亮度的均匀性,提高显示效果。
在一些实施例中,像素的驱动信号包括经由数据线发送至像素的数据驱动信号;
对应的,根据PWM信号的高低电平信号特征,对显示面板中第一显示区域对应像素的驱动信号进行调整,以增加第一显示区域对应像素的存储电容的充电率,包括:S18022、在PWM信号为高电平信号时,增加第一显示区域对应像素的数据驱动信号中高电平信号的持续时长至第一时长。
具体的,在PWM信号为高电平信号时,此时背光模组处于发光状态,对于显示亮度较高的第一显示区域,在受到光照时,会导致该第一显示区域的像素的充电率降低,从而导致该第一显示区域的实际显示亮度低于预设亮度,因此,可以对该区域像素的充电率进行补偿,具体为增加第一显示区域对应像素的数据驱动信号中高电平信号的持续时长至第一时长,其中第一时长大于数据驱动信号中高电平信号的正常持续时长,该第一时长具体可以根据背光模组的背光亮度以及PWM信号的占空比确定。
从而,随着高电平的持续时长增加,充电率也相应增加,在充电率增加后,该第一显示区域的显示亮度相应增加,从而保证显示区域亮度的均匀性,提高显示效果。
在一些实施例中,根据PWM信号对显示面板中不同显示区域对应像素的驱动信号进行调整,以调整不同显示区域对应像素的存储电容的充电率,包括:S18023、根据PWM信号的高低电平信号特征,对显示面板中第二显示区域对应像素的驱动信号进行调整,以减小第二显示区域对应像素的存储电容的充电率。
具体的,对于显示亮度较低的第二显示区域,对该第二显示区域像素的充电率进行补偿,具体为对显示面板中第二显示区域对应像素的驱动信号进行调整,以减小第二显示区域对应像素的存储电容的充电率,在充电率减小后,该第一显示区域的显示亮度相应降低, 从而保证显示区域亮度的均匀性,提高显示效果。
在一些实施例中,根据PWM信号的高低电平信号特征,对显示面板中第二显示区域对应像素的驱动信号进行调整,以减小第二显示区域对应像素的存储电容的充电率,包括:S221、在PWM信号为低电平信号时,减少第二显示区域对应像素的数据驱动信号中高电平信号的持续时长至第二时长,第二时长小于第一时长。
具体的,在PWM信号为低电平信号时,此时背光模组未发光,对于显示亮度较低的第二显示区域,对该第二显示区域像素的充电率进行补偿,具体为减少第二显示区域对应像素的数据驱动信号中高电平信号的持续时长至第二时长,其中,第二时长小于第一时长,且小于数据驱动信号中高电平信号的正常持续时长,该第二时长具体可以根据背光模组的背光亮度以及PWM信号的占空比确定。
从而,在充电率减小后,该第一显示区域的显示亮度相应降低,从而保证显示区域亮度的均匀性,提高显示效果。
在一些实施例中,根据PWM信号对显示面板中不同显示区域对应像素的驱动信号进行调整,以调整不同显示区域对应像素的存储电容的充电率,包括:
S18021、根据PWM信号的高低电平信号特征,对显示面板中第一显示区域对应像素的驱动信号进行调整,以增加第一显示区域对应像素的存储电容的充电率;以及,
S18023、根据PWM信号的高低电平信号特征,对显示面板中第二显示区域对应像素的驱动信号进行调整,以减小第二显示区域对应像素的存储电容的充电率。
具体的,在根据PWM信号对显示面板中不同显示区域对应像素的驱动信号进行调整,以调整不同显示区域对应像素的存储电容的充电率时,也可以是同时增加第一显示区域对应像素的存储电容的充电率,以及减小第二显示区域对应像素的存储电容的充电率,即,在PWM信号为高电平信号时,增加第一显示区域对应像素的数据驱动信号中高电平信号的持续时长至第一时长;在PWM信号为低电平信号时,减少第二显示区域对应像素的数据驱动信号中高电平信号的持续时长至第二时长,第二时长小于第一时长。
从而,通过同时对第一显示区域以及第二显示区域内像素的充电率进行调整,以保证显示区域亮度的均匀性,提高显示效果。
图19为本申请实施例中对像素的数据驱动信号进行调整的示意图,如图19所示,其中,CK表示扫描驱动器对应的扫描驱动信号,TP表示数据驱动器对应的数据驱动信号。
参考图19,对于显示亮度较高的第一显示区域,在PWM信号为高电平信号时,在CK信号的高电平期间,TP信号中高电平信号的正常持续时长为Tc,因此,可以通过增加第一显示区域对应像素的数据驱动信号中高电平信号的持续时长至第一时长Td,以增加第一显示区域对应像素的存储电容的充电率。
另外,对于显示亮度较低的第二显示区域,在PWM信号为低电平信号时,在CK信号的高电平期间,TP信号中高电平信号的正常持续时长为Tc,因此,可以通过减少第二显示区域对应像素的数据驱动信号中高电平信号的持续时长至第二时长Te,以减小第二显示区域对应像素的存储电容的充电率。
