Description

液晶显示装置及其驱动方法 技术领域
本发明涉及液晶显示技术领域,尤其涉及一种液晶显示装置及其驱动方法。
背景技术
液晶显示器，或称LCD(Liquid Crystal Display)，为平面超薄的显示设备，它由一定数量的彩色或黑白像素组成，放置于光源或者反射板前方。液晶显示器功耗很低，并且具有高画质、体积小、重量轻的特点，因此倍受大家青睐，成为显示器的主流。随着社会的发展，中小尺寸的智能手机及PAD越来越普遍地出现在人们的生活中，同时也推进LCD技术的飞速发展，LCD的分辨率从480P到720P，再到目前广泛应用的FHD(全高清，Full High Definition；分辨率为1080*1920)。另外，在中小尺寸的应用中，LCD的刷新率一直维持在60Hz，一直没有得到提高，随着消费者需求的提高，120Hz刷新率的LCD也会成为未来的发展趋势。
液晶显示器通常要包括液晶显示面板和源极驱动模块以及栅极驱动模块。液晶显示面板包括阵列设置的子像素单元，栅极驱动模块逐行开启所述子像素单元，在一行子像素单元被开启时，所述源极驱动模块向该行子像素单元提供数据信号电压。源极驱动模块主要是将数字视频数据转换成模拟视频数据信号电压提供给子像素单元，源极驱动模块的输出通道与每一行的子像素单元的数量是一一对应的，由此使得在一行子像素单元被开启时，所述源极驱动模块可以同时向该行子像素单元提供数据信号电压。但是，源极驱动模块的成本相对较高，因此，业内一直通常以1:3的比例配置源极驱动模块的输出通道与子像素单元的数量，以减少源极驱动模块的输出通道的数量，降低成本。
具体地，如图1所示，以每一行包括6个子像素单元R1、G1、B1、R2、G2、B2为例(实际的液晶面板中应当包括更多数量的子像素单元)，源极驱动模块配置有2个输出通道S1和S2。其中，输出通道S1和S2通过一组第一开关Q1分别连接到子像素单元R1和R2，通过一组第二开关Q2分别连接到子像素单元G1和G2，通过一组第三开关Q3分别连接到子像素单元B1和B2。如图2所示的时序 图，在一行子像素单元被开启的时间内，利用第一开关Q1、第二开关Q2和第三开关Q3的依次切换操作，将输出通道S1和S2输出的数据信号电压分时地提供给对应的子像素单元R1、G1、B1、R2、G2、B2进行充电。图2中，Gate1、Gate2是指行扫描信号，Q1、Q2、Q3分别是指第一开关Q1、第二开关Q2和第三开关Q3的控制信号；其中，H表示一行子像素单元被开启的时间，T1表示行与行扫描之间的间隔时间，T2表示第一开关Q1、第二开关Q2和第三开关Q3进行切换操作的间隔时间，T3表示第一开关Q1、第二开关Q2和第三开关Q3分别开启的时间(即每一子像素的充电时间)。通常地，T1设定为0.9μs，T2至少需要0.3μs，为了提高安全性，T2通常设定为0.6μs。
对于中小尺寸中应用的FHD，分辨率为1080*1920，其显示区域中包括1920的像素，通常地，在垂直方向上通常还包括一些空白的扫描周期VBP(Vsync Back Porch，垂直同步后肩)和VFP(Vsync Front Porch，垂直同步前肩)，VBP+VFP约为60行，因此，在垂直方向上扫描的行数的总数为1980行。按照如上的充电架构，当LCD的刷新率为60Hz时，参阅图2，每行子像素单元被开启的时间H＝1÷60÷1980＝8.4μs，T2以0.6μs计算，则每一子像素的充电时间T3＝1.7μs。对于液晶面板中的子像素，一般需要1μs以上即可完成充电，因此T3通常设定为1.5μs。
但是，按照如上的充电架构，当将LCD的刷新率提升到120Hz时，参阅图2，每行子像素单元被开启的时间H＝1÷120÷1980＝4.2μs，T2以最小的0.3μs计算，T1也减小到0.6μs计算，则每一子像素的充电时间T3＝0.8μs，充电时间小于1μs，将出现充电不足的问题。
发明内容
有鉴于此，本发明提供了一种液晶显示装置及其驱动方法，以解决分辨率为1080*1920(FHD)以上的液晶显示面板在刷新率为120Hz时充电时间不足的问题。
为了实现上述目的，本发明采用了如下的技术方案：
一种液晶显示装置，其中，包括：液晶显示面板，包括M行×N列子像素单元；源极驱动模块，用于产生数据信号电压；所述源极驱动模块包括

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明的具体实施方式进行详细说明。这些优选实施方式的示例在附图中进行了例示。附图中所示和根据附图描述的本发明的实施方式仅仅是示例性的，并且本发明并不限于这些实施方式。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
本实施例首先提供了一种液晶显示装置，如图3所示，所述液晶显示装置包括液晶显示面板10、源极驱动模块20、数据控制模块30、开关驱动模块40以及栅极驱动模块50。
其中，所述液晶显示面板10中设置有M行×N列子像素单元101，所述子像素单元101包括红色子像素R、绿色子像素G和蓝色子像素B。图1中仅示例性的示出了其中的3个子像素单元101，每一行的子像素单元101，红色子像素R、绿色子像素G和蓝色子像素B依次排列且按此周期性地重复排列；其中，M、N均为正整数，通常地，M和N的取值都比较大。
其中，所述源极驱动模块20主要是将数字视频数据转换成模拟视频数据信号电压提供给子像素单元101。栅极驱动模块50主要是向每一行的子像素单元101提供扫描信号，以逐行开启所述子像素单元101，在栅极驱动模块50向一行的子像素单元101提供扫描信号之后，由源极驱动模块20向子像素单元101提供数据信号电压。
其中，所述数据控制模块30是控制源极驱动模块20向子像素单元101充电(提供数据信号电压)的过程，而开关驱动模块40则是用于驱动数据控制模块30的工作状态。
其中，参阅图3和图4，本实施例中，以1:2的比例配置源极驱动模块20的输出通道与每行子像素单元101的数量。即，对于M行×N列子像素单元101，每一行子像素单元101的数量为N个，则所述源极驱动模块20配置有

具体地，在本实施例中，将所述
Figure PCTCN2016083073-appb-000015
个输出通道按顺序依次标示为：S6x+1、S6x+2、S6x+3、S6x+4、S6x+5、S6x+6，其中，x＝0、1、2、…、

将每一行子像素单元101按顺序依次标示为：R4x+1、G4x+1、B4x+1、R4x+2、G4x+2、B4x+2、R4x+3、G4x+3、B4x+3、R4x+4、G4x+4、B4x+4，其中，x＝0、1、2、…、
Figure PCTCN2016083073-appb-000017
其中，所述输出 通道S6x+1通过所述第一开关31连接所述子像素R4x+1，通过所述第二开关32连接所述子像素B4x+1；所述输出通道S6x+2通过所述第一开关31连接所述子像素G4x+1，通过所述第二开关32连接所述子像素R4x+2；所述输出通道S6x+3通过所述第一开关31连接所述子像素G4x+2，通过所述第二开关32连接所述子像素R4x+3；所述输出通道S6x+4通过所述第一开关31连接所述子像素B4x+2，通过所述第二开关32连接所述子像素G4x+3；所述输出通道S6x+5通过所述第一开关31连接所述子像素B4x+3，通过所述第二开关32连接所述子像素G4x+4；所述输出通道S6x+6通过所述第一开关31连接所述子像素R4x+4，通过所述第二开关32连接所述子像素B4x+4。
图4中示出的结构是以x＝0为例进行说明的。如图4中，源极驱动模块20包括输出通道：S1、S2、S3、S4、S5、S6，对应的子像素单元为：R1、G1、B1、R2、G2、B2、R3、G3、B3、R4、G4、B4，数据控制模块30则包括6个第一开关31和6个第二开关32。其中，所述输出通道S1通过一个第一开关31连接所述子像素R1，通过一个第二开关32连接所述子像素B1；所述输出通道S2通过一个第一开关31连接所述子像素G1，通过一个第二开关32连接所述子像素R2；所述输出通道S3通过一个第一开关31连接所述子像素G2，通过一个第二开关32连接所述子像素R3；所述输出通道S4通过一个第一开关31连接所述子像素B2，通过一个第二开关32连接所述子像素G3；所述输出通道S5通过一个第一开关31连接所述子像素B3，通过一个第二开关32连接所述子像素G4；所述输出通道S6通过一个第一开关31连接所述子像素R4，通过一个第二开关32连接所述子像素B4。其中，第一开关31的控制信号M1和第二开关32的控制信号M2是由开关驱动模块40提供的。易于想到的是，在液晶面板的行方向上，周期性地重复着如图4中示出的结构，即重复着x＝1、x＝2、x＝3、…，直至
Figure PCTCN2016083073-appb-000018
时所对应的结构。
如上提供的液晶显示装置的驱动方法具体包括：
由所述栅极驱动模块50逐行向每一行的子像素单元101提供扫描信号，以开启对应行子像素单元101；
由所述源极驱动模块20产生数据信号电压并通过所述
Figure PCTCN2016083073-appb-000019
个输出通道输出；
在一行子像素单元101开启的时间内，由所述开关驱动模块40控制所述数 据控制模块30中的第一开关31和第二开关32进行切换操作，以将所述
Figure PCTCN2016083073-appb-000020
个输出通道输出的数据信号电压分时地提供给对应的子像素单元101。
还是以图4示出的结构为例，栅极驱动模块50向子像素单元为R1、G1、B1、R2、G2、B2、R3、G3、B3、R4、G4、B4提供扫描信号之后，开关驱动模块40控制所述数据控制模块30中的第一开关31导通(此时第二开关32断开)，源极驱动模块20的输出通道S1～S6分别将数据信号电压输入到子像素单元R1、G1、G2、B2、B3、R4，然后开关驱动模块40再将数据控制模块30中的第二开关32导通(此时第一开关31断开)，源极驱动模块20的输出通道S1～S6分别将数据信号电压输入到该行其余的子像素单元B1、R2、R3、G3、G4、B4，最终完成一整行的子像素的充电。
参阅图4以及如图5所示的时序图，在一行子像素单元被开启的时间内，利用第一开关31和第二开关32的依次切换操作，将输出通道输出的数据信号电压分时地提供给对应的子像素单元进行充电。图5中，Gate1、Gate2是指行扫描信号，M1、M2分别是指第一开关31和第二开关32的控制信号；其中，H表示一行子像素单元被开启的时间，T1表示行与行扫描之间的间隔时间，T2表示第一开关31、和第二开关32进行切换操作的间隔时间，T3表示第一开关31和第二开关32分别开启的时间(即每一子像素的充电时间)。通常地，T1设定为0.6～0.9μs，T2至少需要0.3μs。其中，所述开关控制模块40控制所述第一开关31和第二开关32按照等时长的关系进行切换操作，即第一开关31和第二开关32开启的时间是一样的。
进一步地，如上提供的液晶显示装置及其驱动方法，主要是保证分辨率为1080×1920以上，刷新率为120Hz的液晶显示面板具有足够的充电时间。
以分辨率为1080*1920，刷新率为120Hz为例，参阅图5，每行子像素单元被开启的时间H＝1÷120÷1980＝4.2μs，T1设定为0.6μs，T2设定为0.3μs，则每一子像素的充电时间T3＝1.35μs，充电时间大于1μs，满足充电时间的要求。
进一步地，在本实施例中，源极驱动模块20中相邻两个输出通道输出的数据信号电压的极性相反，并且，每传输完成一帧画面的数据，所述输出通道输出的数据信号电压的极性反转一次。具体地，还是以图4示出的结构为例，若在第i帧画面中，设定输出通道S1、S3、S5输出的数据信号电压为正极性，则输出通道S2、S4、S6输出的数据信号电压为负极性，对应地像素单元R1、B1、G2、 R3、B3、G4为正极性充电，像素单元G1、R2、B2、G3、R4、B4为负极性充电；并且，在第i+1帧画面中，输出通道S1、S3、S5输出的数据信号电压应当反转为负极性，输出通道S2、S4、S6输出的数据信号电压应当反转为正极性，对应地像素单元R1、B1、G2、R3、B3、G4为负极性充电，像素单元G1、R2、B2、G3、R4、B4为正极性充电。由此，在一帧画面的显示中，同一行像素单元相邻两个子像素单元的充电电压极性相反，在相邻两帧画面的显示中，同一子像素单元的充电电压极性相反。由此可以提供液晶显示面板的显示品质，延长液晶寿命。
需要说明的是，以上所述的输出通道输出的数据信号电压为正极性或负极性，是指输出通道输出的数据信号电压与液晶显示面板的公共电压相比较而言的，若输出通道输出的数据信号电压大于公共电压则为正极性，若输出通道输出的数据信号电压小于公共电压则为负极性。
综上所述，本发明实施例提供的液晶显示装置及其驱动方法，以1:2的比例配置源极驱动模块的输出通道与每行子像素单元的数量，在尽可能减少源极驱动模块的输出通道的数量的同时，解决了分辨率为1080*1920(FHD)以上的LCD在刷新率为120Hz时充电时间不足的问题。
