技术领域
本公开文本涉及显示技术领域,尤其涉及一种显示装置、电子设备和驱动方法。
背景技术
随着技术的发展,触摸屏已经逐步取代了传统的按键成为新一代的输入设备。根据不同的实现原理,触摸屏可以分为电阻式、电容式、表面声波式、红外式等等。目前被广泛使用的是电阻式和电容式触摸屏技术。
由于内嵌式触摸屏,可以将触摸屏与液晶显示器(LCD)集成到一起,从而可降低成本和模组厚度,提高透过率。因此,内嵌式触摸屏已成为应用最为广泛的触摸屏类型。
目前,广泛采用的内嵌式触摸屏的驱动方式是分时驱动方式(V-Blank方式),即将一显示周期(例如一帧显示时间)中的部分时间用作触控侦测阶段,另一部分时间作为显示阶段。通过分时驱动的方式分别实现显示与触控侦测的功能,且做到互不影响。
但是随着触摸显示屏的尺寸不断增大,分辨率不断增高,在确保显示的同时,能够压缩出留给触控侦测的时间变得很短,而随着触控侦测时间的减少甚至不能保证,因此对于触摸显示屏的触控侦测的影响是非常严重的。

具体实施方式
下面结合附图和实施例,对本公开文本的具体实施方式做进一步描述。以下实施例仅用于说明本公开文本,但不用来限制本公开文本的范围。
为使本公开文本实施例的目的、技术方案和优点更加清楚,下面将结合本公开文本实施例的附图,对本公开文本实施例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公开文本的一部分实施例,而不是全部的实施例。基于所描述的本公开文本的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开文本保护的范围。

为使本公开文本的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开文本进行详细描述。
以下提供的各个实施例都是以内嵌式触控显示装置为例进行说明,但是本领域技术人员能够理解的是,本公开文件所提供的技术方案同样可以应用于其他类型的显示装置中,而不以此为限。
本公开文本实施例提供了一种内嵌式触控显示装置,该内嵌式触控显示装置具体可以包括一触控显示区域4。
如图1所示,该内嵌式触控显示装置具体可还可以包括:
显示驱动模块1,用于向触控显示区域中的第一子区域加载显示驱动信号,以使第一子区域处于显示状态,该第一子区域是触控显示区域中预先划分的至少两个子区域中的一个;
触发信号生成模块2,用于当显示驱动模块1向触控显示区域中的第一子区域加载显示驱动信号时,生成一触发信号,所述触发信号包括所述第一 子区域的信息;以及
触控驱动信号生成模块3,用于根据接收的触发信号,向触控显示区域中除第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号,以使当第一子区域处于显示状态时,触控显示区域内的其他子区域处于触控侦测状态。
本公开文本实施例中,可预先将内嵌式触控显示装置中所包括的触控显示区域4划分为若干子区域,例如图2所示的子区域的41、42,或者其他实施例中的更多子区域。
那么,本公开文本实施例中,当触控显示区域4中一子区域,例如子区域41,在显示驱动模块1所发送的显示驱动信号的驱动下,显示相应的图像画面,即处于显示状态时,触控显示区域4中的其他子区域,例如子区域42,可在触控驱动信号生成模块3所发送的触控驱动信号控制下,对该子区域是否发生触摸操作进行侦测,即处于触控侦测状态,而不显示相应的图像画面。从而可使触控显示区域4内的不同区域,在同一时刻内,分别处于显示状态和触控侦测状态,以在触控显示区域4内,分区域同步实现画面显示和触控侦测。
由于本公开文本实施例所提供的内嵌式触控显示装置,可实现画面显示和触控侦测的分区域同步实现,因此可克服触摸显示屏尺寸对于触控侦测时间的影响,解决了大尺寸触摸显示屏触控侦测时间不足的问题,确保触控显示装置在正常画面显示的同时,实现触控侦测,实现画面显示和触控侦测的完美结合。
而且,由于本公开文本实施例中采用了显示驱动和触控侦测同步实现的驱动方式,从而相较于现有技术中分时驱动方式,增加了触控侦测的时间。不但可以确保内嵌式触控显示装置可以实现触控侦测功能,还可以降低触控侦测信号的发送频率,降低触控显示装置的内部噪声,提高触控显示装置的画面显示质量。
在一具体实施例中,若当处于触控侦测状态的子区域存在多个时,本公开文本实施例所涉及的触控驱动信号生成装置3可同步向多个处于触控侦测状态的子区域所在位置处的触控侦测电极7加载触控侦测信号,以使多个处 于触控侦测状态的子区域同步实现触控侦测。由于每一子区域需要进行触控侦测的面积小于触控显示区域整体的面积,因此在需要触控侦测的触控显示区域1面积减少的情况下,可有效延长一子区域的触控侦测时间,确保触控侦测功能的实现。此外,还可进一步降低触控侦测信号(例如触控感应信号、触控驱动信号等)的发送频率,降低触控显示装置的内部噪声,提高显示质量。
本公开文本实施例中,显示驱动模块1具体可用于在一帧扫描时间内向触控显示区域4中的第一子区域加载显示驱动信号,以使第一子区域处于显示状态。
而本公开文本实施例所涉及的触控驱动信号生成模块3,可用于在一帧扫描时间内根据接收的触发信号,向触控显示区域4中除第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号,以使当第一子区域处于显示状态时,其他子区域处于触控侦测状态。
以图2为例对本公开文本实施例所提供的内嵌式触控显示装置分区域同步实现显示驱动和触控侦测进行简要说明。
图2中,在一帧扫描时间内的第一时段内,若当前子区域41需要显示相应的画面即需要处于显示状态,则子区域42可进行触控侦测即处于触控侦测状态。那么,本公开文本实施例中,显示驱动模块1可向子区域41加载显示驱动信号,以使子区域41处于显示状态。当显示驱动模块1向子区域41发送显示驱动信号时,触发信号生成模块2生成一触发信号,以使触控信号生成装置3向其他子区域例如子区域42加载触控驱动信号,该触发信号包括当前处于显示状态的子区域例如子区域41的信息,并将该触发信号发送至触控驱动信号生成装置3。触控驱动信号生成装置3在接收到该触发信号后,获知当前处于显示状态的子区域信息,例如子区域41当前为显示状态,则触控驱动信号生成装置3向触控显示区域4中的其他子区域,例如子区域42所在位置处的触控驱动电极7加载触控侦测信号,以使例如子区域42等其他子区域处于触控侦测状态。从而在第一时段内,使触控显示区域4中的不同子区域,例如子区域41和子区域42同步处于显示状态和触控侦测状态。
由于栅线是逐行扫描的,即图2所示的触控显示区域4中,当子区域41 结束显示状态时,子区域42会处于显示状态。那么,在所述一帧扫描时间内的第二时段内,显示驱动模块1可向子区域42加载显示驱动信号,以使子区域42处于显示状态。当显示驱动模块1向子区域42发送显示驱动信号时,触发信号生成模块2生成一触发信号,该触发信号包括当前处于显示状态的子区域例如子区域42的信息,并将该触发信号发送至触控驱动信号生成装置3。触控驱动信号生成装置3在接收到该触发信号后,获知当前处于显示状态的子区域信息,例如子区域42当前为显示状态,则触控驱动信号生成装置3向触控显示区域4中的其他子区域,例如子区域41所在位置处的触控驱动电极7加载触控侦测信号,以使例如子区域41等其他子区域处于触控侦测状态。从而在第二时段内,使触控显示区域4中的不同子区域,例如子区域41和子区域42同步处于显示状态和触控侦测状态。
本公开文本实施例所提供的内嵌式触控显示装置内,在触控显示区域4内,可包括多根栅线、像素电极、公共电极等与显示驱动有关的器件(附图未示出)。那么,为了驱动上述显示器件,如图3所示,本公开文本实施例所涉及的显示驱动模块1内具体可以以下器件中的至少一种:
栅极驱动信号生成单元11,用于生成栅极驱动信号并将生成的栅极驱动信号加载至对应的栅线,栅极驱动信号生成单元11与栅线对应连接。
像素电极驱动信号生成单元12,用于生成像素电极驱动信号并将生成的像素电极驱动信号加载至对应的像素电极,像素电极驱动信号生成单元12与像素电极连接。
公共电极信号生成单元13,用于生成公共电极信号并将生成的公共电极光信号加载至公共电极,公共电极信号生成单元13与公共电极连接。
若本公开文本实施例所涉及的内嵌式触控显示装置中还包括其他与显示驱动有关的器件,则本公开文本实施例中还可以对应包括其他用于生成相应显示驱动信号的功能单元。
本公开文本实施例所提供的内嵌式触控显示装置,如图4所示,具体可以包括成盒设置的第一基板5和第二基板6。
其中,第一基板5上可设置有用于通过与触控驱动电极7相互作用实现触控侦测的触控感应电极8。
而本公开文本实施例所涉及的触控驱动电极7具体可设置于第二基板6中,且与触控感应电极8绝缘相交设置。
本公开文本实施例所涉及的触控驱动电极7,如图2所示,具体可以包括多个沿纵向平行设置的电极,每个电极由多个电连接的块状电极而成。
本公开文本实施例所涉及的触控感应电极8,如图2所示,具体可以包括多个沿横向平行设置的条状电极。
另外,上述本公开文本实施例所涉及的栅线、像素电极以及公共电极等显示驱动器件,具体可以设置于第二基板6上。
本公开文本实施例所涉及的第一基板5,具体可为彩膜基板。另外,本公开文本实施例所涉及的第二基板6,具体可为阵列基板。
由于本公开文本实施例所提供的内嵌式触控显示装置,可同步实现显示驱动和触控侦测,因此可能会导致触控驱动电极7加载触控驱动信号,与第二基板6中的数据线(source)9加载数据信号同时出现的情况下。这种情况下,可能会对第二基板6中设置的数据线9所传输的数据信号产生一定的影响。那么,为了避免触控驱动信号与数据信号之间相互影响的情况,在本公开文本一实施例中,如图5所示,第二基板6在触控驱动电极7与数据线9之间设置有屏蔽层10,以实现对触控驱动信号与数据信号之间信号串扰的屏蔽,从而可进一步降低了内嵌式触控显示装置的内部噪声,提高了触控显示装置的显示质量。
本公开文本实施例中,可在第二基板6中屏蔽层10所在的层上,涂覆整层的相应材质以作为屏蔽层10,从而可以更好的实现屏蔽的作用。
另外,为了节省材质,以及为了避免屏蔽触控侦测信号,如图5所示,本公开文本实施例中所涉及的屏蔽层10也可以可由多个与数据线9设置位置相对应的条状图案组成,且一条数据线9对应至少一个屏蔽层10的条状图案。
在一具体实施例中,如图5所示,数据线9与屏蔽层10的条状图案可为一一对应的关系。那么,一数据线9在第二基板6上的投影区域,可完全存在于该数据线9对应的一屏蔽层10条状图案在第二基板6上的投影区域之内。即一条屏蔽层10的条状图案,完全覆盖其对应的一条数据线9,从而避免触控驱动信号与数据信号之间相互影响。
为了避免对触控显示装置正常显示产生影响,本公开文本实施例所涉及的屏蔽层10的材质具体可由透明导电材质,例如氧化铟锡(ITO)等。
本公开文本实施例中,如图6所示,不同子区域所在位置处的触控驱动电极7可连接同一触控驱动信号生成装置3。这样,可由同一触控驱动信号生成装置3,向处于触控侦测状态的不同子区域所在位置处的触控驱动电极7,同步或按预设时间间隔加载触控感应信号。
而在另一具体实施例中,如图7所示,不同子区域所在位置处的触控驱动电极7也可分别连接不同的触控驱动信号生成装置3(如标识31、32所示)。例如,一子区域所在位置处的触控驱动电极3可单独连接一触控驱动信号生成装置3,即一对一的关系。这样,一触控驱动信号生成装置3,可单独向其对应的子区域(处于触控侦测状态)所在位置处的触控感应电极7加载触控驱动信号。并且,多个触控驱动信号生成装置3可同步或按预设时间间隔,向各自对应的、处于触控侦测状态的子区域所在位置处的触控感应电极7加载触控感应信号。
在本公开文本的其他实施例中,一触控驱动信号生成装置3也可以与两个或以上子区域所在位置处的触控驱动电极7对应连接。
本公开文本实施例还提供了一种内嵌式触控显示装置驱动方法,如图8所示,该方法具体可以包括:
向触控显示区域4中的第一子区域加载显示驱动信号,以使第一子区域处于显示状态,该第一子区域是触控显示区域4中预先划分的至少两个子区域中的一个;
当向触控显示区域中的第一子区域加载显示驱动信号时,生成一触发信号,该触发信号中包括第一子区域信息;
根据该触发信号,向触控显示区域4中除所述第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号,以使当所述第一子区域处于显示状态时,所述其他子区域处于触控侦测状态。
在一具体实施例中,上述根据所述触发信号,向所述触控显示区域4中除所述第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号包括:
当所述其他子区域存在多个时,同步向多个其他子区域所在位置处的触控驱动电极7加载触控驱动信号。
在一具体实施例中,上述向触控显示区域4中的第一子区域加载显示驱动信号,以使第一子区域处于显示状态,第一子区域为触控显示区域4中预先划分的至少两个子区域中的一个的过程具体可以包括:
在一帧扫描时间内向触控显示区域4中的第一子区域加载显示驱动信号,以使第一子区域处于显示状态;
上述根据该触发信号,向触控显示区域4中除第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号,以使当第一子区域处于显示状态时,其他子区域处于触控侦测状态的过程具体可以包括:
在一帧扫描时间内根据接收的触发信号,向触控显示区域4中除第一子区域之外的其他子区域所在位置处的触控驱动电极7加载触控驱动信号,以使当第一子区域处于显示状态时,其他子区域处于触控侦测状态。
在一具体实施例中,在一帧扫描时间的第一时段,本公开文本实施例所提供的内嵌式触控显示装置驱动方法具体可以包括:
向第一子区域加载第一显示驱动信号,以使第一子区域在第一时段处于显示状态;
