Description

液晶面板像素的驱动控制方法及液晶显示面板 【技术领域】
本发明涉及显示技术领域，特别是涉及一种液晶面板像素的驱动控制方法及液晶显示面板。
【背景技术】
随着液晶显示器(LCD)的发展，人们对LCD清晰度要求也越来越高，相同尺寸下显示器的分辨率要求也越来越高，对面板尺寸的需求也越来越大。
现有的液晶显示面板的结构通常包括：对盒而置的阵列基板和彩膜基板；其中，阵列基板包括由沿第一方向延伸的一组数据线和沿第二方向延伸的一组栅线界定的呈阵列分布的多个像素单元，每一个像素单元内包括一个TFT(Thin Film Transistor，薄膜场效应晶体管，简称TFT)，彩膜基板包括彩色滤光片。液晶显示面板是利用栅极驱动电路驱动液晶显示面板上的TFT来控制数据线充电时间，结合数据线上电压以满足对像素进行充放电，以实现正常的影像显示。目前的液晶面板像素充电的驱动方法包括以下步骤，其时序图如图1所示：
S1，当栅极驱动电路GATE_(N)为高电平周期(即GATE(N)在一帧的开启时间T)时，TFT开启，液晶面板像素通过SOURCE_(N)电压进行充电。
S2，第一阶段(即画面切换的第一帧)，当栅极驱动电路GATE_(N)为高电平时，TFT开启时，SOURCE_(N)提供-V1电压对液晶面板像素电容(包括CLC电容和CST电容)进行充电，经过一个时间周期T(即一帧的时间)后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压-V1。
S3，第N阶段，当栅极驱动电路GATE_(N)为高电平时，TFT开启时，SOURCE_(N)提供+VN电压对液晶面板像素电容(包括CLC电容和CST电容)进行充电，经过一个时间周期T后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压+VN。
S4，第N+1阶段，当栅极驱动电路GATE_(N)为高电平时，TFT开启时， SOURCE_(N)提供-V(N+1)电压对液晶面板像素电容(包括CLC电容和CST电容)进行充电，经过一个时间周期T后，液晶面板像素电容完成充电，使液晶面板像素电压到达SOURCE_(N)充电电压-V(N+1)。
S5，重复S1～S4步骤，完成画面的刷新。
为了满足不断提高的液晶显示面板的分辨率要求，一方面分辨率的增加需要增加大量的数据线(SOURCE)与栅线(GATE)，使得单个像素充电时间越来越短；另一方面，面板尺寸的增加，直接使得数据线与栅极线长度不断的增加，数据线与栅极驱动电路的负载较大，数据线与栅极驱动电路的电压信号衰减严重；导致电压不足以使每个像素电压达到饱和状态，进而使得液晶显示面板的显示质量降低。
【发明内容】

【具体实施方式】
下面结合附图和具体实施方式对本发明进行详细说明。
一种液晶面板像素的驱动控制方法，该方法中液晶面板画面切换一帧所需的时间为一个充电周期，至少一个充电周期包括高压充电阶段和电压修正阶段。 高压充电阶段的电压幅值大于预设电压幅值，以使液晶像素在较短的时间内快速积累电量。电压修正阶段的电压等于预设电压，以使电压准确定位在预设电压值。
区别于现有技术，本发明通过将一个充电周期分为高压充电阶段和电压修正阶段，由于将预设电压放大，因而可以补偿线路损耗造成的压降，从而能使液晶像素在较短时间内快速积累电量，然后再以预设电压值对电压进行修正，使得电压准确定位在预设电压值。避免了因时间短，负载损耗大而造成的液晶像素充电不足的问题，从而能使液晶像素短时间内能达到预设电压值，提高了液晶显示面板的显示质量。
参阅图3，是本发明液晶面板像素的驱动控制方法的第一实施例的流程示意图。图4是图3的驱动控制方法的驱动时序图。
本实施例中，有多个充电周期包括高压充电阶段和电压修正阶段时，每个高压充电阶段的电压幅值相对于预设电压幅值的放大倍数相同。且每个高压充电阶段的充电时间相同。
举例而言，本实施例的液晶面板切换N+1帧画面中经过了N+1个充电阶段，即经过N+1个充电周期。本实施例中，该N+1个充电周期均包括高压充电阶段和电压修正阶段。其中，一个充电周期为T，画面切换第1帧时的预设电压值为V1，画面切换第N帧时的预设电压值为VN，画面切换第N+1帧时的预设电压值为V(N+1)。
具体而言，本实施例的液晶面板像素的驱动控制方法包括以下步骤：
S100，当栅极驱动电路GATE_(N)为高电平周期(即GATE(N)在一帧的开启时间T)时，TFT开启，液晶面板像素通过SOURCE_(N)电压进行充电。
S101，第一阶段，即画面切换第一帧，当栅极驱动电路GATE_(N)为高电平时，将SOURCE_(N)提供的-V1电压放大到n*(-V1)(其中：n＞1)，以n*(-V1)的电压对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为 T/m个周期(其中：m＞1且m为整数)，随后充电电压恢复到电压-V1，以对像素的预定充电电压进行修正，充电时间长度为T*(1-1/m)个周期，至此，完成一个时间总长度为周期T(即一帧的时间)后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压-V1。
S102，第N阶段，画面切换第N帧，将SOURCE_(N)提供的+VN电压放大到n*(+VN)(其中：n＞1)，对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为T/m个周期(其中：m＞1且m为整数)，随后充电电压恢复到电压+VN，以对像素的预定充电电压进行修正，充电时间长度为T*(1-1/m)个周期，至此，完成一个时间总长度为周期T(即一帧的时间)后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压+VN。
S103，第N+1阶段，画面切换第N+1帧，将SOURCE_(N)提供为-V(N+1)电压放大到n*(-V(N+1))(其中：n＞1)，对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为T/m个周期(其中：m＞1且m为整数)，随后充电电压恢复到电压-V(N+1)，以对像素的预定充电电压进行修正，充电时间长度为T*(1-1/m)个周期。至此，完成一个时间总长度为周期T(即一帧的时间)后，液晶面板像素电容完成充电，使液晶面板像素电压到达SOURCE_(N)充电电压-V(N+1)。
S104，重复步骤S100～S103来完成画面的刷新。
本实施例中，各个阶段中的n值和m值都相等，即每个阶段的高压充电阶段的电压幅值相对于预设电压值放大的倍数都相等，且每个阶段中的高压充电阶段的时间都相等。
参阅图5，是本发明液晶面板像素的驱动控制方法的第二实施例的流程示意图。
本实施例中，有多个充电周期包括高压充电阶段和电压修正阶段时，其中至少两个充电周期中的高压充电阶段的电压幅值相对于预设电压幅值的放大倍 数不同。至少两个高压充电阶段的充电时间不同。
举例而言，本实施例的液晶面板切换N+1帧画面中经过了N+1个充电阶段，即经过N+1个充电周期。本实施例中，该N+1个充电周期均包括高压充电阶段和电压修正阶段。其中，一个充电周期为T，画面切换第1帧时的预设电压值为V1，画面切换第N帧时的预设电压值为VN，画面切换第N+1帧时的预设电压值为V(N+1)。
具体而言，本实施例的液晶面板像素的驱动控制方法包括以下步骤：
S200，当栅极驱动电路GATE_(N)为高电平周期(即GATE(N)在一帧的开启时间T)时，TFT开启，液晶面板像素通过SOURCE_(N)电压进行充电。
S201，第一阶段，即画面切换第一帧，将SOURCE_(N)提供的-V1电压放大到n1*(-V1)(其中：n1＞1)，以n1*(-V1)的电压对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为T/m1个周期(其中：m1＞1，且m1为整数)，随后充电电压恢复到电压-V1，以对像素的预定充电电压进行修正，充电时间长度为T*(1-1/m1)个周期，至此，完成一个时间总长度为周期T(即一帧的时间)后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压-V1。
S202，第N阶段，画面切换第N帧，将SOURCE_(N)提供为+VN电压放大到nN*(+VN)(其中：nN＞1)，对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为T/mN个周期(其中：mN＞1，且mN为整数)，随后充电电压恢复到电压+VN，以对像素电预定充电电压进行修正，充电时间长度为T*(1-1/mN)个周期，至此，完成一个时间总长度为周期T(即一帧的时间)后，液晶面板像素电容完成充电，液晶面板像素电压到达SOURCE_(N)充电电压+VN。
S203，第N+1阶段，画面切换第N+1帧，将SOURCE_(N)提供为-V(N+1)电压放大到n(N+1)*(-V(N+1))(其中n(N+1)＞1)，对液晶面板像素电容(包括CLC电容和CST电容)进行充电，充电时间为T/m(N+1)个周期(其中：m(N+1)＞1，且m(N+1)为整数)，随后充电电压恢复到电压-V(N+1)，以对像素电预定充电电压进行修正，充电时间长度为T*(1-1/m(N+1)个周期，至此，完成一个时间总长度为周期T(即 一帧的时间)后，液晶面板像素电容完成充电，使液晶面板像素电压到达SOURCE_(N)充电电压-V(N+1)。
S204，重复步骤S200～S203完成画面的刷新。
本实施例中，n1、nN、......以及n(N+1)均不相等，即针对不同的帧，n可以进行变化调整。同样，针对不同的帧，m也可以进行调整，所以m1、mN、......以及m(N+1)也可以都不相等。
当然，除了本实施例的情况外，还可以是n1、nN、......以及n(N+1)中至少两个不相等，而m1、mN、......以及m(N+1)都相等。或者，n1、nN、......以及n(N+1)都相等，而m1、mN、......以及m(N+1)中至少两个不相等。
参阅图6，是本发明液晶面板像素的驱动控制方法的第三实施例中高压充电阶段的流程示意图。
本实施例中，高压充电阶段包括多个高压充电次级阶段，至少两个高压充电次级阶段的电压幅值不相等。多个高压充电次级阶段的电压幅值呈递减趋势。
例如，在第一阶段中，包括以下步骤：
S3010，将SOURCE_(N)提供的-V1电压放大到nY*(-V1)(其中：nY＞1)，充电时间为t1。
S3011，再将电压调整为n(Y-1)*(-V1)，充电时间为t2。
S3012，再将电压调整为n(Y-2)*(-V1)，充电时间为t3。
......
S(Y-1)，将电压调整为n2*(-V1)，充电时间为t(Y-1)。
SY，再将电压调整为n1*(-V1)，充电时间为tY。
本实施例是将第一阶段中的高压充电阶段分为Y个高压充电次级阶段，每个高压充电次级阶段的电压幅值不相等，并呈递减趋势，即nY＞n(Y-1)＞n(Y-2)＞......＞n2＞n1，每个高压充电次级阶段的充电时间之和为高压充电阶段的时间，即t1+t2+t3+......+t(Y-1)+tY＝T/m。
电压从高到低，最后的电压值是最接近预设电压值的，因而能防止电压从高压阶段放大的电压变到预设电压时跳变过大引起闪烁等问题。
此外，nY、n(Y-1)、n(Y-2)、......、n2、n1之间还可以满足以下关系：nY＜n(Y-1)＜n(Y-2)＜......＜n(x+1)＜nx＞n(x-1)＞......＞n3＞n2＞n1。即，多个高压充电次级阶段的电压幅值还可以呈先递增再递减的趋势。
当然，高压充电阶段分为多个高压充电次级阶段不仅适用于第一阶段中，也适用于其他阶段，可以只有一个充电周期的高压充电阶段分成多个高压充电次级阶段，也可以有多个充电周期的高压充电阶段分成多个高压充电次级阶段。并且，每个高压充电阶段的次级阶段的段数以及电压幅值的趋势可以相同也可以不同。
请参阅图7和图8，图7是本发明的液晶显示面板的结构示意图。图8是图7中阵列基板的电路结构示意图。
本发明进一步提高了一种液晶显示面板，包括液晶盒1、阵列基板2和彩膜基板3，阵列基板1和彩膜基板3分别位于液晶盒1的两侧。阵列基板2包括沿第一方向延伸的一组数据线21和沿第二方向延伸的一组栅线22界定的呈阵列分布的多个像素单元23，每一个像素单元23内包括一薄膜场效应晶体管。彩膜基板3包括彩色滤光片。数据线21用于对像素进行充电，数据线21的充电电压包括第一充电电压和第二充电电压，第一充电电压的电压幅值大于像素的预设电压值，第二充电电压的电压幅值等于像素的预设电压值。
本发明在高压充电阶段将预设电压放大，将补偿线路损耗造成的压降，从而能使液晶像素在较短时间内快速积累电量，在电压修正阶段以预设电压值对电压进行修正，使得电压准确定位在预设电压值。避免了因时间短，负载损耗大而造成的液晶像素充电不足的问题，从而能使液晶像素短时间内能达到预设电压值，提高了液晶显示面板的显示质量。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
