Description
技术领域
本发明总体说来涉及液晶显示技术领域,更具体地讲,尤其涉及一种全嵌入式触摸屏以及包括所述全嵌入式触摸屏的移动装置。
背景技术
随着液晶显示技术的飞速发展,触摸屏(TouchScreenPanel)已经逐渐遍及人们的生活,其中,嵌入式(in-cell)触摸屏由于其能使得整个面板变得更加轻薄的优点得到了很多终端设备厂商的青睐并成为了未来的发展趋势。
嵌入式触摸屏是将触摸电路嵌入到显示面板中以实现触摸面板和显示面板的一体化,目前,对于全嵌入式(full-in-cell)触摸屏的架构,一般将触摸传感器设置在薄膜晶体管(TFT)的一侧(如图1所示)。这里,嵌入式触摸屏可以分为互电容和自电容触摸屏,其中,自电容触摸屏利用自电容的原理实现检测手指触摸位置,具体为:在触摸屏中设置多个同层设置且相互绝缘的触摸传感器,当人体未触碰屏幕时,各触摸传感器所承受的电容为一固定值,当人体触碰屏幕时,触碰位置对应的触摸传感器所承受的电容为固定值叠加人体电容,触控侦测芯片在触控时间段通过检测各触摸传感器的电容值变化可以判断出触控位置。其中,为了同时实现显示和触控功能,对于嵌入式触摸屏,需要对用于实现触摸功能的触摸电路和用于实现显示的显示电路进行驱动,以分别实现触摸屏的触摸功能和显示功能。现有的驱动方法中,通常是分时对触摸电路和显示电路进行扫描,即在驱动触摸屏显示的同时,停止侦测触摸屏上的触摸操作。
通常,在将嵌入式显示屏应用于手机领域时,手机厂商推出了很多新的触摸功能,例如,在手机待机模式下,通过一个特定手势(例如,双击手势)唤醒手机使其进入特定的应用程序,在这种情况下,需要不断对触摸电路进行扫描,以侦测是否进行手势唤醒,因此,对于自电容内嵌式触摸屏,触控侦测芯片在触控时间段内需要不断进行检测,由于触摸传感器也可作为公共电极(Vcom),则会通过储能电容而耦合到TFT的S极(源极),无论是方波或弦波,都会造成耦合到TFT的S极的电荷为同一极性的电荷(如图2所示),如果手机长时间处于黑屏的待机模式下(即,液晶分子长时间被施加同一电荷)时则会使液晶被极化,造成画面显示异常。
因此,现有的嵌入式触摸屏无法使终端的液晶显示屏长时间处于待机模式时不被极化。
发明内容
有鉴于此,本发明目的是提供一种全嵌入式触摸屏以及包括所述全嵌入式触摸屏的移动装置,通过改进全嵌入式触摸屏的架构,以克服现有的液晶显示屏长时间处于待机模式时被极化的问题。
根据本发明示例性实施例的一方面,提供一种全嵌入式触摸屏,包括以矩阵方式排列的多个传感器垫、沿所述矩阵的列方向布置的多条数据线以及连接到所述多条数据线的数据驱动器,其特征在于,所述全嵌入式触摸屏还包括设置在所述多条数据线上的多个晶体管,其中,每条数据线上设置有所述多个晶体管中的一个晶体管,每个晶体管的漏极连接到相应的数据线,每个晶体管的源极连接到一个传感器垫,并且所述多个晶体管的栅极共同连接到数据驱动器的特定使能端。
可选地,每个晶体管的源极连接到与相应的数据线相邻的一列传感器垫中的最下端的传感器垫。
可选地,每个晶体管的源极连接到任意一个传感器垫。
可选地,所述多个传感器垫与公共电极以分时复用方式工作,其中,在液晶面板正常显示时间段期间,所述多个传感器垫作为公共电极工作,在触摸扫描时间段期间,所述多个传感器垫执行触摸扫描。
可选地,所述全嵌入式触摸屏还包括与所述全嵌入式触摸屏一体化的液晶面板、驱动液晶面板的栅极驱动器以及将栅极驱动信号传输到液晶面板的多条栅极线,其中,所述多条数据线连接到液晶面板,以将数据驱动器的数据信号传输到液晶面板。
可选地,液晶面板待机时间段包括多个帧,每个帧都具有预定的触摸扫描时间段,所述多个传感器垫在每个帧的预定的触摸扫描时间段中执行触摸扫描,其中,在第M帧至第N帧期间,数据驱动器的所述特定使能端输出低电平信号,栅极驱动器不输出栅极驱动信号,在第N+1帧期间,在触摸扫描时间段之后的清屏时间段中,数据驱动器的所述特定使能端输出高电平信号,栅极驱动器向所述多条栅极线逐条发送栅极驱动信号,所述多个传感器垫作为公共电极工作,其中,M和N为大于1的自然数且N大于M。
可选地,在清屏时间段中,所述公共电极的电压电平为地电平。
根据本发明示例性实施例的另一方面,提供一种移动装置,包括如上述任一种所述全嵌入式触摸屏。
根据本发明示例性实施例提供的全嵌入式触摸屏以及包括所述全嵌入式触摸屏的移动装置,可通过在全嵌入式触摸屏中增加多个晶体管的方式得到一种新型的全嵌入式触摸屏,通过这种改进能够有效地释放掉在触摸扫描期间耦合到液晶端的电荷,从而避免了由于液晶被极化而导致的画面显示异常情况的发生。
附图说明
通过下面结合附图进行的详细描述,本发明示例性实施例的上述和其它目的、特点和优点将会变得更加清楚,其中:
图1示出现有技术的全嵌入式触摸屏的剖面示意图;
图2示出现有技术的全嵌入式触摸屏中的显示电路的示意图;
图3示出根据本发明示例性实施例的全嵌入式触摸屏的结构示意图;
图4示出根据本发明示例性实施例的全嵌入式触摸屏在正常显示时的时序图;
图5示出根据本发明示例性实施例的全嵌入式触摸屏在待机时的时序图。
具体实施方式
现将详细参照本发明的示例性实施例,所述实施例的示例在附图中示出,其中,相同的标号始终指的是相同的部件。以下将通过参照附图来说明所述实施例,以便解释本发明。
图3示出根据本发明示例性实施例的全嵌入式触摸屏的结构示意图。
如图3所示,根据本发明示例性实施例的全嵌入式触摸屏包括:以矩阵方式排列的多个传感器垫TPpq(p和q为不小于1的整数)、沿所述矩阵的列方向布置的多条数据线St(t为不小于1的整数)、连接到所述多条数据线St的数据驱动器(图3中未示出)以及设置在所述多条数据线上的多个晶体管Ta(a为不小于1的整数),其中,每条数据线上设置有所述多个晶体管中的一个晶体管,每个晶体管的漏极连接到相应的数据线,每个晶体管的源极连接到一个传感器垫,并且所述多个晶体管的栅极共同连接到数据驱动器的特定使能端CLEAR_EN。这里,作为示例,所述晶体管可以是场效应晶体管(例如,NMOS管等)。应注意,以下将以NMOS管为例来说明各个示例性实施例。
这里,由于全嵌入式触摸屏的所有传感器垫可同时进行收发信号,并且在触摸扫描阶段后都会接至地准位,因此,可有多种方式将每个晶体管的源极连接至各个传感器垫。例如,所述每个晶体管的源极可连接到与相应的数据线相邻的一列传感器垫中的最下端的传感器垫。譬如说,参照图3,S1至S10条数据线所对应的晶体管T1至T10的源极可共同和与其相邻的第一列传感器垫中的最下端的传感器垫TP1q相连。通过这种方式,可使全嵌入式触摸屏的内部走线更加规范,从而节省了制备成本。此外,作为另一示例,所述每个晶体管的源极还可连接到任意一个传感器垫。
此外,由于全嵌入式触摸屏是将触摸电路嵌入到显示面板中以实现触摸面板和显示面板的一体化,因此,通常,设置于终端中的显示面板可以是集中触摸和显示功能的显示面板。
这里,作为附件部件,所述全嵌入式触摸屏可还包括与所述全嵌入式触摸屏一体化的液晶面板、驱动液晶面板的栅极驱动器以及将栅极驱动信号传输到液晶面板的多条栅极线(在图1中未示出),其中,所述多条数据线连接到液晶面板,以将数据驱动器的数据信号传输到液晶面板。
作为示例,为了实现全嵌入式触摸屏可同时实现触摸检测功能和显示功能,全嵌入式触摸屏可采用传感器垫与公共电极分时复用的工作方式,例如,在与所述全嵌入式触摸屏一体化的液晶面板正常显示时间段期间,所述多个传感器垫作为公共电极工作,在触摸扫描时间段期间,所述多个传感器垫执行触摸扫描。
图4示出根据本发明示例性实施例的全嵌入式触摸屏在正常显示时的时序图。如图4所示,在液晶面板正常显示期间可包括多个帧,每个帧都具有预定的触摸扫描时间段和正常显示时间段,由图4可知,当液晶面板处于正常显示时间段期间,所述多个传感器垫可作为公共电极工作,在触摸扫描时间段期间,可对所述多个传感器垫进行触摸驱动。
此外,除了可在全嵌入式触摸屏正常显示的情况下进行触摸扫描之外,当液晶面板处于黑屏待机期间,同样需要进行触摸扫描,以检测用户是否对全嵌入式触摸屏执行了触摸操作。
下面结合图5来详细描述根据本发明示例性实施例的全嵌入式触摸屏待机时的示例。具体说来,如图5所示,液晶面板待机时间段可包括多个帧,每个帧都具有预定的触摸扫描时间段,所述多个传感器垫在每个帧的预定的触摸扫描时间段中执行触摸扫描(如图5所示,在执行出没扫描时,传感器垫可由于用户触摸而产生脉冲信号)。更具体地讲,在第M帧至第N帧期间,数据驱动器的特定使能端CLEAR_EN输出低电平信号,栅极驱动器不输出栅极驱动信号。此时,数据线可处于高阻态。此外,在第M帧至第N帧中的每个帧的触摸扫描时间段期间,多个传感器垫执行触摸扫描,在第M帧至第N帧中的每个帧的黑屏待机时间段内,多个传感器垫作为公共电极工作,且公共电极的电压电平为地电平。其后,在第N+1帧期间,在执行触摸扫描的触摸扫描时间段之后的清屏时间段中,数据驱动器的特定使能端CLEAR_EN输出高电平信号,栅极驱动器向所述多条栅极线逐条发送栅极驱动信号,所述多个传感器垫作为公共电极工作。此时,设置在每条数据线上的晶体管导通,从而每条数据线可通过导通的晶体管连接到公共电极。这里,作为示例,在清屏时间段中,所述公共电极的电压电平为地电平。
也就是说,由于在清屏时间段中,数据驱动器的所述特定使能端输出高电平信号,因此,以NMOS管为例,每个NMOS管可响应于其栅极接收到的高电平信号导通,使得所述多条数据线与所述多个传感器垫相连,并且,由于所述多个传感器垫在清屏时间段作为公共电极工作,因此,可清除在触摸扫描阶段耦合到液晶上的电荷,从而防止液晶被极化,同时,也降低了数据驱动器的功耗。
此外,基于同一发明构思,本发明示例性实施例还提供一种包括上述全嵌入式触摸屏的移动装置。作为示例,所述移动装置可以是手机、平板电脑、电视机、显示器、笔记本电脑、导航仪等任何具有显示功能的产品或部件。
综上所述,在根据本发明示例性实施例的全嵌入式触摸屏以及包括所述全嵌入式触摸屏的移动装置中,可通过在全嵌入式触摸屏中增加多个晶体管的方式得到一种新型的全嵌入式触摸屏,通过这种改进能够有效地释放掉在触摸扫描期间耦合到液晶端的电荷,从而避免了由于液晶被极化而导致的画面显示异常情况的发生。
显然,本发明的保护范围并不局限于上诉的具体实施方式,本领域的技术人员可以对发明进行各种改动和变型而不脱离本发明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
