Description

液晶显示面板及其3D显示时的像素插黑方法 技术领域
本发明涉及液晶显示技术领域,具体地讲,涉及一种液晶显示面板及其3D显示时的像素插黑方法。
背景技术
三维(Three Dimensions,简称3D)立体电视的3D立体技术主要有偏光式(即主动式)和快门式(即被动式)两种,其中,快门式3D立体技术利用眼镜的左右开关以及电视图像的左右帧同步交替,使眼睛看到快速切换的不同图像画面,从而在大脑中产生立体影像。
在快门式3D立体技术中,当左右眼图像画面交替显示时,容易产生串扰(Crosstalk)问题。该串扰问题指的是:左眼接收的左眼图像中包含有右眼图像的内容,而右眼接收的右眼图像中包含有左眼图像的内容,即左右眼图像相互干扰,从而导致形成的3D图像发生错误。
为了消除这种串扰问题,目前在快门式3D立体技术中采用插入黑画面的方式解决,例如可以采用左眼画面→黑画面→右眼画面→黑画面(LBRB),使得左眼同时接收到左眼画面以及黑画面,右眼同时接收到右眼画面以及黑画面,由于黑画面为背景画面,不会与正常画面发生串扰。插黑技术(Black Insertion,BI)普遍使用在平面显示设备中,以改善显示面板的动态影像的显示质量。插黑技术是利用在连续的动态影像与影像之间,插入黑画面,以消除人眼对影像的积分效应(Integration Effect),进一步改善显示面板在动态影像中常有的动画拖影现象(Moving Picture Response Timing,MPRT),提升显示画面的质量。
然而,这种插黑技术需要更高的刷新频率,以左右眼分别要实现60Hz的刷新频率为例,需要平面显示设备的驱动电路具有240Hz的刷新频率,功耗增加的同时提高了成本,并且这种驱动方式还会带来显示画面的亮度较低,液晶 电容充电时间较短等缺点。
发明内容
为了解决上述现有技术存在的问题,本发明的目的在于提供一种液晶显示面板,包括:若干条数据线、若干条扫描线、若干个像素,其中,每个像素连接其对应的一条数据线和一条扫描线,其中,所述液晶显示面板还包括若干个控制晶体管,其中,每个控制晶体管的栅极均连接同一条扫描线,每个控制晶体管的源极连接其对应的一条数据线,每个控制晶体管的漏极均连接在一起。
进一步地,所述像素包括像素晶体管、存储电容及液晶电容,其中,所述像素晶体管的栅极连接其对应的一条扫描线,所述像素晶体管的源极连接其对应的一条数据线,所述存储电容与所述液晶电容的一端均连接所述像素晶体管的漏极,所述存储电容与所述液晶电容的另一端均连接公共电极。
进一步地,每个控制晶体管的漏极均连接公共电极。
进一步地,在第2n帧画面的空白时域将若干控制晶体管与若干像素的像素晶体管均导通,其中,n为正整数。
进一步地,第2n-1帧画面的扫描顺序与第2n帧画面的扫描顺序相反。
进一步地,在第n帧画面的空白时域将若干控制晶体管与若干像素的像素晶体管均导通,其中,n为正整数。
进一步地,第n帧画面的扫描顺序与第n+1帧画面的扫描顺序相同,且第n+2帧画面的扫描顺序与第n+3帧画面的扫描顺序相同,且第n+1帧画面的扫描顺序与第n+2帧画面的扫描顺序相反。
本发明的另一目的还在于提供一种上述的液晶显示面板3D显示时的像素插黑方法,其包括:在第2n帧画面的空白时域将若干控制晶体管与若干像素的像素晶体管均导通,其中,n为正整数。
进一步地,第2n-1帧画面的扫描顺序与第2n帧画面的扫描顺序相反。
本发明的又一目的又在于提供一种上述的液晶显示面板3D显示时的像素插黑方法,其包括:在第n帧画面的空白时域将若干控制晶体管与若干像素的 像素晶体管均导通,其中,n为正整数。
进一步地,第n帧画面的扫描顺序与第n+1帧画面的扫描顺序相同,且第n+2帧画面的扫描顺序与第n+3帧画面的扫描顺序相同,且第n+1帧画面的扫描顺序与第n+2帧画面的扫描顺序相反。
本发明在两帧画面的时间内显示一副完整的三维立体画面,可使液晶显示面板的驱动电路具有比现有技术的刷新频率低一半的刷新频率,降低功耗的同时降低了成本,并且本发明在一帧画面的空白时域插入黑画面,可使显示画面的亮度提升,液晶电容充电时间增加。

以下将对根据本发明的第一实施例的液晶显示面板进行三维(Three Dimensions,简称3D)显示时的像素插黑方法进行详细描述。应当理解的是,根据本发明的第一实施例的液晶显示面板也可进行二维(Two Dimensions,简称2D)显示。
表1示出了根据本发明的第一实施例的液晶显示面板进行3D显示时的一种像素插黑方法。在表1中,n为正整数,符号“↑”表示液晶显示面板的扫描方向(即扫描顺序)是从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,符号“↓”表示液晶显示面板的扫描方向(即扫描顺序)是从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120。

从表1中可知,从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,以实现第2n-1帧画面的显示;接着从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120,以实现第2n帧画面的显示;而后在第2n帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示,这样可使左眼单独观看一副完整的三维立体画面。
从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,以实现第2n+1帧画面的显示;接着从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120,以实现第2n+2帧画面的显示;而后在第2n+2帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示,这样可使右眼单独观看一副完整的三维立体画面。
表2示出了根据本发明的第一实施例的液晶显示面板进行3D显示时的另一种像素插黑方法。在表2中,m为正整数,符号“↑”表示液晶显示面板的扫描方向(即扫描顺序)是从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,符号“↓”表示液晶显示面板的扫描方向(即扫描顺序)是从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120。
[表2]
Figure PCTCN2014090739-appb-000002
从表2中可知,从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,以实现第m帧画面的显示;接着在第m帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示。然后,从液晶显示面板的最后一条扫描线120顺序扫描至第二条扫描线120,以实现第m+1帧画面的显示;接着在第m+1帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示。这样可使左右眼单独观看一帧画面,从而在大脑中产生由左右眼单独观看到的一帧画面合成的三维立体画面。
接着,从液晶显示面板的从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120,以实现第m+2帧画面的显示;在第m+2帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示。然后,从液晶显示面板的第二条扫描线120顺序扫描至最后一条扫描线120,以实现第m+3帧画面的显示;接着在第m+3帧画面的空白时域通过控制将液晶显示面板的所有薄膜晶体管(即所有的像素晶体管141和控制晶体管150)导通,从而将液晶显示面板的所有数据线110连至公共电极130。此时,液晶显示面板上的正极性的像素140的像素电压降低,而负极性的像素140的像素电压升高,最终达到相同的电压,即最终的电压非常接近于公共电极130的电压,从而使液晶显示面板实现黑画面的显示。这样可使左右眼单独观看一帧画面,从而在大脑中产生由左右眼单独观看到的一帧画面合成的三维立体画面。
综上,左右眼在两帧画面的时间内观看到一副完整的三维立体画面,可使液晶显示面板的驱动电路具有比现有技术的刷新频率低一半的刷新频率,降低功耗的同时降低了成本。并且上述两种像素插黑方法还会带来显示画面的亮度提升,液晶电容充电时间增加等优点。
图2是根据本发明的第二实施例的液晶显示面板的结构示意图。
第二实施例与第一实施例在此不再赘述,只描述与第一实施例的不同之处。参照图2,第二实施例与第一实施例的不同之处在于:每个控制晶体管150的漏极均连接在一起且均与公共电极130连接。
此外,根据本发明的第二实施例的液晶显示面板进行3D显示时的像素插黑方法可采用上述表1或上述表2所描述的像素插黑方法,在此也不再赘述。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
