Description

液晶显示器 技术领域
本申请属于显示技术领域，具体地讲，涉及一种液晶显示器。
背景技术
随着光电与半导体技术的演进，也带动了平板显示器(Flat Panel Display)的蓬勃发展，而在诸多平板显示器中，液晶显示器(Liquid Crystal Display，LCD)因具有高空间利用效率、低消耗功率、无辐射以及低电磁干扰等诸多优越特性，已被应用于生产生活的各个方面。
在液晶显示器中，通常包括液晶面板、背光模块以及驱动液晶面板和背光模块的驱动模块，其中液晶面板包括对盒设置的彩色滤光片基板(即CF基板)和阵列基板(即Array基板)以及夹设于二者之间的液晶。在范例性的大尺寸液晶面板中，较多采用负型VA(Vertically Aligned)液晶，然而负型VA液晶存在较多的缺陷，尤其是需要呈现较大的视角时，采用负型VA型液晶的液晶面板在被大视角观看时会出现色偏现象。
为了解决上述缺陷，在采用负型VA型液晶的液晶面板中往往将各子像素再分为Main/Sub次像素，并向Main/Sub次像素提供不同的像素电压。但是，这样的像素设计往往需要再增加金属走线和薄膜晶体管(TFT)来驱动Main/Sub次像素，从而造成开口率的牺牲，使液晶面板的透光率下降，为了维持原有的透光率，就需要提升背光模块出射的光线亮度，从而直接提升背光模块的成本。

通过结合附图进行的以下描述，本申请的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本申请的实施例的液晶显示器的结构示意图；

具体实施方式
以下，将参照附图来详细描述本申请的实施例。然而，可以以许多不同的 形式来实施本申请，并且本申请不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本申请的原理及其实际应用，从而使本领域的其他技术人员能够理解本申请的各种实施例和适合于特定预期应用的各种修改。
图1是根据本申请的实施例的液晶显示器的结构示意图。
参照图1，根据本申请的实施例的液晶显示器包括：液晶面板10、驱动模块20、背光模块30。
液晶面板10可以包括对盒设置的彩色滤光片基板(即CF基板)和阵列基板(即Array基板)以及夹设于二者之间的负型VA液晶。也就是说，液晶面板10为一具有VA显示模式的液晶面板。此外，彩色滤光片基板和阵列基板的具体结构以及如何由彩色滤光片基板、阵列基板和负型VA液晶构成液晶面板10在此不再赘述。
在组装形成液晶显示器的过程中，将液晶面板10和背光模块30面对设置，再借由外框等固定结构将二者结合固定。驱动模块20驱动背光模块30出射光线，以提供给液晶面板10所用。在图1中，为了便于实施例的描述，未示出液晶面板10和背光模块30的组装状态。
液晶面板10包括A×B个液晶像素(即子像素)P 11、P 12、……、P AB。液晶像素P ab(其中1≤a≤A，1≤b≤B，且a和b均为整数)可以是红色液晶像素、绿色液晶像素或蓝色液晶像素，但本申请并不限制于此。而且这些液晶像素P 11、P 12、……、P AB中必须包括至少一个红色液晶像素、至少一个绿色液晶像素和至少一个蓝色液晶像素。作为一种优选方案，在列方向上均为同一颜色的液晶像素，在行方向上以红色液晶像素、绿色液晶像素和蓝色液晶像素为组顺序排列。
在本实施例的液晶面板10中，不再将各个液晶像素再分为Main/Sub次像素。为了使大视角观看液晶面板10时不会出现色偏现象，本实施例采取的技术方案为：将液晶面板10设置为在相邻两帧中显示同一画面；驱动模块20在相邻两帧中分别向每个液晶像素提供高低不同的同极性像素电压，以使每个液晶像素的液晶分子偏转；其中在相邻两帧的每一帧中，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同。
也就是说，液晶面板10的帧刷新频率被提高了一倍，例如液晶面板10的帧刷新频率为120HZ，具体的帧刷新频率的提高方法可参照现有技术的相关内容，在此不再赘述。
接下来对上述的本实施例采取的技术方案进行进一步阐述。
继续参照图1，在相邻两帧的前一帧中，驱动模块20向液晶像素P ab提供高像素电压(或低像素电压)，以使液晶像素P ab的液晶分子偏转，而驱动模块20向液晶像素P (a-1)b、液晶像素P a(b-1)、液晶像素P a(b+1)以及液晶像素P (a+1)b均提供了低像素电压(或高像素电压)。
在相邻两帧的后一帧中，驱动模块20向液晶像素P ab提供低像素电压(或高像素电压)，以使液晶像素P ab的液晶分子偏转，而驱动模块20向液晶像素P (a-1)b、液晶像素P a(b-1)、液晶像素P a(b+1)以及液晶像素P (a+1)b均提供了高像素电压(或低像素电压)。
也就是说，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同。并且每个液晶像素在相邻的前后两帧中被提供的像素电压的高低不同。需要说明的是，所述高像素电压和所述低像素电压的极性相同，这样液晶面板10在相邻的前后两帧中能够显示同一画面。
此外，所述高像素电压和所述低像素电压为事先已经根据输入的RGB信号 且按照需要补偿的视角效果所决定，一般是以查找表(LUT)的方式记录在驱动模块10中。例如，以8bit的驱动信号为例，输入的RGB信号中的每一对应256对高低像素电压，这样共有3*256个高像素电压和3*256个低像素电压。
进一步地，再参考图2、图3所示，本实施例进一步提供这种液晶面板10的控制电路结构。液晶面板10还包括显示区60和围设于所述显示区60四周的非显示区70。
所述显示区60设置有像素阵列，每个像素单元晶体管阵列基板(图中未显示)；所述非显示区70设置有：所述驱动模块20以及源极控制芯片71和栅极控制芯片72，所述驱动模块20和所述源极控制芯片71和所述栅极控制芯片72位于所述显示区60的同一侧。
其中，所述源极控制芯片71通过数据线与所述晶体管阵列基板中的晶体管的源极(图中未显示)电性连接；所述栅极控制芯片72通过扫描线(图中未显示)与所述晶体管的栅极(图中未显示)电性连接。
具体地，栅极控制芯片72为栅极控制芯片G1。源极控制芯片71包括源极控制芯片S1、源极控制芯片S2、源极控制芯片S3和源极控制芯片S4。栅极控制芯片G1通过扫描线与显示区60内的薄膜晶体管的栅极(图中未显示)连接。源极控制芯片S1、源极控制芯片S2、源极控制芯片S3和源极控制芯片S4分别通过覆晶薄膜封装方式(Chip On Film，COF)固定在柔性电路板80上，并由柔性电路板80与印刷电路板(Printed Circuit Board Assembly，PCBA)90连接。源极控制芯片S1、源极控制芯片S2、源极控制芯片S3和源极控制芯片S4还通过数据线与显示区60内的薄膜晶体管的源极连接，从而由源极控制芯片S1、源极控制芯片S2、源极控制芯片S3和源极控制芯片S4和栅极控制芯片G1对薄膜晶体管阵列进行控制，进而实现显示区的画面显示。
本实施例中的源极控制芯片和栅极控制芯片的数量仅仅为示例，在其他的实施例中，还可以根据液晶显示屏的大小以及控制芯片的结构进行确定。
综上，通过在相邻两帧中分别向每个液晶像素提供高低不同的同极性像素电压，且在相邻两帧的每一帧中，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同，从而使液晶面板10在相邻两帧中显示同一画面的同时，实现低色偏视角补偿效果，即在大视角方向观看液晶面板10时，不会出现色偏现象。
为了克服相邻两帧中液晶面板10的各液晶像素显示的亮度不平均而造成的闪烁不适现象，进一步地，对背光模块30进行亮度区域的划分，通过动态调节各亮度区域的亮度，来使液晶面板10的各液晶像素显示亮度均匀，从而消除闪烁现象，具体请参照图4所示的液晶显示器。图4是根据本申请的另一实施例的液晶显示器的结构示意图。以下仅对图4所示的实施例与图1所示的实施例的不同之处进行说明。
参照图4，与图1所示的实施例不同的是，将液晶面板10划分为M×N个矩形面板分区10 11、10 12、……、10 MN，且将背光模块30划分为M×N个矩形背光分区30 11、30 12、……、30 MN，其中矩形面板分区10 ij与矩形背光分区30 ij相对对应，1≤i≤M，1≤j≤N，且i和j均为整数。这里，需要说明的是，矩形面板分区10 ij中包括的液晶像素的数量相同，但作为其他实施方式，也可以不同。
这样，矩形面板分区10 ij中所有液晶像素的像素电压之和与矩形背光分区30 ij的亮度满足下面的式子1。
[式子1]  L ij_1*V ij_1＝L ij_2*V ij_2
其中，L ij_1表示相邻两帧的前一帧中矩形面板分区10 ij的亮度，V ij_1表示相邻两帧的前一帧中矩形面板分区10 ij中所有液晶像素的像素电压之和；L ij_2表示 相邻两帧的后一帧中矩形背光分区30 ij的亮度，V ij_2表示相邻两帧的后一帧中矩形背光分区30 ij中所有液晶像素的像素电压之和。
这里，由于液晶像素的像素电压与液晶像素的光线穿透率成正比，液晶像素的光线穿透率与背光亮度的乘积即为液晶像素的显示亮度，也就是说液晶像素的像素电压与背光亮度的乘积能够表示液晶像素的显示亮度。当相邻的前后两帧中矩形背光分区30 ij的亮度与矩形面板分区10 ij中所有液晶像素的像素电压之和的乘积相等时，矩形面板分区10 ij在相邻前后两帧中的显示亮度就相同，从而能够消除闪烁现象。
在液晶面板10和背光模块30均被划分区域后，关于背光模块30向液晶面板10提供显示光线的方式可以包括以下两种方式，当然，以下描述的两种方式仅为示例，本申请还可以包括其他合适的方式。
背光模块30向液晶面板10提供显示光线的第一种方式为：在相邻两帧的每一帧中，在所有的矩形面板分区10 11、10 12、……、10 MN中的所有液晶像素的液晶分子偏转之后，驱动模块20驱动所有的矩形背光分区30 11、30 12、……、30 MN同时出射光线。当然，应当理解的是，各个矩形背光分区的亮度可以不同，也可以相同，其各自由驱动模块20负责调控。
背光模块30向液晶面板10提供显示光线的第二种方式为：在相邻两帧的每一帧中，在矩形面板分区10 ij中的所有液晶像素的液晶分子偏转之后，驱动模块20驱动矩形背光分区30 ij出射光线，直至驱动所有的矩形背光分区30 11、30 12、……、30 MN出射光线。也就是说，驱动模块20分时驱动各个矩形背光分区。当然，也应当理解的是，各个矩形背光分区的亮度可以不同，也可以相同，其各自由驱动模块20负责调控。
为了使液晶面板10显示的画面的亮度与未做低色偏视角补偿效果的液晶面 板显示的画面的亮度相同，进一步地，使液晶面板10的各矩形面板分区在相邻两帧中显示的同一画面的亮度之和为未做低色偏视角补偿效果的液晶面板在一帧中显示所述画面的亮度的两倍。具体技术方案如下。
矩形面板分区10 ij中所有液晶像素的像素电压之和与矩形背光分区30 ij的亮度满足下面的式子2。
[式子2]  L ij_1*V ij_1+L ij_2*V ij_2＝2*L ij*V ij
其中，L ij表示当未做低色偏视角补偿的液晶面板被设置为仅在一帧中显示所述画面时相应矩形背光分区的亮度，V ij表示当未做低色偏视角补偿的液晶面板被设置为仅在一帧中显示所述画面时相应矩形面板分区中所有液晶像素的像素电压之和。需要说明的是，未做低色偏视角补偿的液晶面板在不同帧中显示的画面不相同。
以下对液晶显示器的驱动方法进行说明。图5是图1所示的液晶显示器的驱动方法的流程图。
参照图1和图5，根据本申请的实施例的液晶显示器的驱动方法包括：
S310：在相邻两帧的前一帧中，驱动模块20向液晶面板10的每个液晶像素提供像素电压，以使每个液晶像素的所有液晶分子偏转；

其中，在前一帧和后一帧中，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同，且同一个液晶像素的像素电压极性相同且高低不同。

其中，在前一帧和后一帧中，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同，且同一个液晶像素的像素电压极性相同且高低不同。

S530：在相邻两帧的后一帧中，驱动模块20向液晶面板10的每个液晶像素提供像素电压，以使每个液晶像素的所有液晶分子偏转；
S540：在相邻两帧的后一帧中，在液晶面板10的矩形面板分区10 ij中的所 有液晶像素的液晶分子偏转之后，驱动模块20驱动矩形背光分区30 ij出射光线，,直至驱动所有的矩形背光分区30 11、30 12、……、30 MN出射光线；
其中，在前一帧和后一帧中，每个液晶像素的像素电压的高低都与其上下左右相邻的液晶像素的像素电压的高低不同，且同一个液晶像素的像素电压极性相同且高低不同。
此外，进一步地，在图6和图7所示的驱动方法中，矩形面板分区10 ij中所有液晶像素的像素电压之和与矩形背光分区30 ij的亮度满足上面的式子1和/或式子2。
