Description

列翻转模式的液晶显示面板及其驱动方法 技术领域
本发明涉及显示技术领域,尤其涉及一种列翻转模式的液晶显示面板及其驱动方法。
背景技术
液晶显示器(Liquid Crystal Display,LCD)具有机身薄、省电、无辐射等众多优点,得到了广泛的应用,如:液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等,在平板显示领域中占主导地位。
现有市场上的液晶显示器大部分为背光型液晶显示器,其包括液晶显示面板及背光模组(backlight module)。液晶显示面板的工作原理是在薄膜晶体管基板(Thin Film Transistor Array Substrate,TFT Array Substrate)与彩色滤光片基板(Color Filter,CF)之间灌入液晶分子,并在两片基板上施加驱动电压来控制液晶分子的旋转方向,以将背光模组的光线折射出来产生画面。
液晶显示面板包括多个呈阵列式排布的像素,每个像素电性连接一个薄膜晶体管(TFT),该TFT的栅极(Gate)连接至水平扫描线,漏极(Drain)连接至竖直方向的数据线,源极(Source)则连接至像素电极。在水平扫描线上施加足够的电压,会使得电性连接至该条扫描线上的所有TFT打开,从而数据线上的信号电压能够写入像素,控制液晶的透光度,实现显示效果。
液晶分子具有一种特性,如果长时间给液晶分子施加同向电压,会使液晶分子极化,即使将电压取消,液晶分子亦会因为特性的破坏而无法再因电场的变化而转动,因此液晶显示面板必须是通过交流驱动,在显示画面的时候以一定的频率去翻转液晶分子,防止液晶分子固定偏向同一个方向而失去活性。目前,液晶显示面板支持多种翻转模式,比如点翻转模式、行翻转模式、列翻转模式等,实现翻转的途径主要是通过不断交替TFT源极电压的正、负极性(即信号电压的正、负极性),或不断交替公共电极的正、负极性,以达到交流驱动的目的。而液晶显示面板在正常工作时,由于TFT正、负极性的源极电压(即信号电压)与栅极电压形成的电压差不 同,在相同的时间内,TFT源极对像素的充电效果会表现出不同,进一步造成显示画面内各个像素的亮暗不一,最终导致画面显示效果不均匀。
图1所示为一种现有的列翻转模式的液晶显示面板的电路图,图2为对应于图1所示电路的时序图。请参阅图1,现有的列翻转模式的液晶显示面板包括多条相互平行并依次排列的竖直的数据线、多条相互平行并依次排列的水平的扫描线、及呈阵列式排布的多个像素,每个像素内均设置像素驱动电路,同一行像素内的多个像素驱动电路均电性连接于对应该行像素的扫描线,同一列像素内的多个像素驱动电路均电性连接于对应该列像素的数据线。所述像素驱动电路包括:驱动薄膜晶体管T1,所述驱动薄膜晶体管T1的栅极电性连接于对应该像素所在行的扫描线,源极电性连接于对应该像素所在列的数据线,漏极电性连接于存储电容CST1的一端及液晶电容CLC1的一端;存储电容CST1,所述存储电容CST1的另一端电性连接于公共电极VCOM;液晶电容CLC1,所述液晶电容CLC1的另一端电性连接于公共电极VCOM。由于图1所示的液晶显示面板采用列翻转模式驱动,请参阅图3、图4,每相邻两列像素的驱动薄膜晶体管T1的源极电压的极性相反,每相邻两帧之间同一像素的驱动薄膜晶体管T1的源极电压的极性相反。具体地,结合图1、图2,该现有的列翻转模式的液晶显示面板显示一帧画面的驱动过程为:多条扫描线依次逐行进行扫描,设N、M为正整数,当扫描到第N条扫描线时,第N条扫描线向该第N行像素的驱动薄膜晶体管T1的栅极提供扫描信号GATE(N),第N行像素的所有驱动薄膜晶体管T1均开启,对于相邻的第M列、第M+1列像素,第M列数据线S(M)向第N行第M列像素的驱动薄膜晶体管T1的源极写入正极性电压,写入时间长度为t;与第M列数据线S(M)相邻的第M+1列数据线S(M+1)向第N行第M+1列像素的驱动薄膜晶体管T1的源极写入负极性电压,写入时间长度也为t;由于第N行第M列像素的驱动薄膜晶体管T1的源极电压的极性为正,而第N行第M+1列像素的驱动薄膜晶体管T1的源极电压的极性为负,且第N行第M列像素与第N行第M+1列像素的驱动薄膜晶体管T1的栅极电压相同,则第M列、第M+1列像素的驱动薄膜晶体管的源极电压与栅极电压形成的电压差不同,在第M列像素与第M+1列像素充电时间相同(均为t1)的情况下,两列像素的充电效果会表现出不同,造成第M列像素与第M+1列像素的显示亮暗不一,最终导致画面显示效果不均匀。

请同时参阅图5至图7,本发明首先一种列翻转模式的液晶显示面板,包括多条相互平行并依次排列的竖直的数据线、多条相互平行并依次排列的水平的扫描线、及呈阵列式排布的多个像素,每个像素内均设置像素驱动电路;同一行像素内的多个像素驱动电路均电性连接于对应该行像素的扫描线;分别位于每条数据线左、右两侧的一奇数列像素与一偶数列像素内的多个像素驱动电路均电性连接于该条数据线。
所述像素驱动电路包括:驱动薄膜晶体管T1、充电控制薄膜晶体管、存储电容CST1、及液晶电容CLC1。
所述驱动薄膜晶体管T1的栅极电性连接于像素所在行对应的扫描线,源极电性连接于充电控制薄膜晶体管的漏极,漏极电性连接于存储电容CST1的一端及液晶电容CLC1的一端;所述充电控制薄膜晶体管的栅极电性连接于时钟信号CK,源极电性连接于像素所在列对应的数据线;所述存储电容CST1的另一端及液晶电容CLC1的另一端均电性连接于公共电极VCOM。
偶数列像素内的充电控制薄膜晶体管T2与奇数列像素内的充电薄膜晶 体管T2’的其中之一受高电位的控制而打开,另一个受低电位的控制而打开。进一步地,所述奇数列像素内的充电控制薄膜晶体管T2’为P型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为N型薄膜晶体管;或所述奇数列像素内的充电控制薄膜晶体管T2’为N型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为P型薄膜晶体管。
所述时钟信号CK交替提供高、低电位,控制偶数列像素内的充电控制薄膜晶体管T2’与奇数列像素内的充电薄膜晶体管T2交替打开。
以所述奇数列像素内的充电控制薄膜晶体管T2’为P型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为N型薄膜晶体管为例,所述列翻转模式的液晶显示面板显示相邻两帧画面时:前一帧画面内,所述扫描线逐行提供时长为第一时长t1的扫描信号,所述时钟信号CK先提供时长为第二时长t2的高电位控制偶数列像素内的充电控制薄膜晶体管T2打开,于此同时,数据线提供正极性电压,使得偶数列像素内的驱动薄膜晶体管T1的源极电压为正极性,对偶数列像素进行充电;之后,所述时钟信号CK再提供时长为第三时长t3的低电位控制奇数列像素内的充电控制薄膜晶体管T2打开,于此同时,数据线提供负极性电压,使得奇数列像素内的驱动薄膜晶体管T1的源极电压为负极性,对奇数列像素进行充电;
后一帧画面内,所述扫描线逐行提供时长为第一时长t1的扫描信号,所述时钟信号CK先提供时长为第三时长t3的高电位控制偶数列像素内的充电控制薄膜晶体管T2打开,于此同时,数据线提供负极性电压,使得偶数列像素内的驱动薄膜晶体管T1的源极电压为负极性,对偶数列像素进行充电;之后,所述时钟信号CK再提供时长为第二时长t2的低电位控制奇数列像素内的充电控制薄膜晶体管T2打开,于此同时,数据线提供正极性电压,使得奇数列像素内的驱动薄膜晶体管T1的源极电压为正极性,对奇数列像素进行充电。
所述第一时长t1为第二时长t2与第三时长t3的加和。
具体地,所述第三时长t3不等于第二时长t2,所述第三时长t3大于第二时长t2,即负极性电压的充电时长不等于正极性电压的充电时长,且负极性电压的充电时长大于正极性电压的充电时长。通过对所述时钟信号CK进行脉宽调制来调整所述第二、第三时长t2、t3的长短,进而调整负极性电压与正极性电压的充电时长。所述驱动薄膜晶体管T1、充电控制薄膜晶体管T2均为低温多晶硅薄膜晶体管、氧化物半导体薄膜晶体管、或非晶硅薄膜晶体管。

本发明所提供的列翻转模式的液晶显示面板,通过在像素驱动电路中增加充电控制薄膜晶体管T2,并依据数据线提供的电压的正、负极性不同,调整提供给充电控制薄膜晶体管T2栅极的时钟信号CK的电位高低及脉冲宽度,控制正、负极性电压分别对相邻两列像素进行充电的时间,能够平衡正、负极性电压对相邻两列像素的充电效果,补偿正、负极性电压对相邻两列像素造成的充电差异,使得画面显示效果均匀。
请参阅图8,本发明还提供一种列翻转模式的液晶显示面板的驱动方法,包括如下步骤:
步骤1、提供列翻转模式的一液晶显示面板。
如图5所示,所述列翻转模式的液晶显示面板包括多条相互平行并依次排列的竖直的数据线、多条相互平行并依次排列的水平的扫描线、及呈阵列式排布的多个像素,每个像素内均设置像素驱动电路;同一行像素内的多个像素驱动电路均电性连接于对应该行像素的扫描线;分别位于每条数据线左、右两侧的一奇数列像素与一偶数列像素内的多个像素驱动电路均电性连接于该条数据线。
所述像素驱动电路包括:驱动薄膜晶体管T1、充电控制薄膜晶体管、存储电容CST1、及液晶电容CLC1。
所述驱动薄膜晶体管T1的栅极电性连接于像素所在行对应的扫描线,源极电性连接于充电控制薄膜晶体管的漏极,漏极电性连接于存储电容CST1的一端及液晶电容CLC1的一端;所述充电控制薄膜晶体管的栅极电性连接于时钟信号CK,源极电性连接于像素所在列对应的数据线;所述存储电容CST1的另一端及液晶电容CLC1的另一端均电性均连接于公共电极VCOM。
偶数列像素内的充电控制薄膜晶体管T2与奇数列像素内的充电薄膜晶体管T2’的其中之一受高电位的控制而打开,另一个受低电位的控制而打开。进一步地,所述奇数列像素内的充电控制薄膜晶体管T2为P型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为N型薄膜晶体管;或所述奇数列像素内的充电控制薄膜晶体管T2’为N型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为P型薄膜晶体管。
具体地,所述驱动薄膜晶体管T1、充电控制薄膜晶体管T2均为低温多晶硅薄膜晶体管、氧化物半导体薄膜晶体管、或非晶硅薄膜晶体管。
步骤2、驱动所述列翻转模式的液晶显示面板进行一帧画面的显示。
请结合图5与图6,以所述奇数列像素内的充电控制薄膜晶体管T2’为P型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为N型薄膜晶体管为例,设N、M为正整数,对于第N行像素,第N条扫描线向第N行像素的驱动薄膜晶体管T1的栅极提供时长为第一时长t1的扫描信号GATE(N),所述时钟信号CK先提供时长为第二时长t2的高电位控制第N行偶数列像素内的充电控制薄膜晶体管T2打开,于此同时,对应的数据线S(M)提供正极性电压,使得第N行偶数列像素内的驱动薄膜晶体管T1的源极电压为正极性,对第N行偶数列像素进行充电;之后,所述时钟信号CK再提供时长为第三时长t3的低电位控制第N行奇数列像素内的充电控制薄膜晶体管T2打开,于此同时,对应的数据线S(M)提供负极性电压,使得第N行奇数列像素内的驱动薄膜晶体管T1的源极电压为负极性,对第N行奇数列像素进行充电;所述第一时长t1为第二时长t2与第三时长t3的加和。
按同样方式依次逐行扫描,直至完成对一帧画面的驱动。
具体地,所述第三时长t3不等于第二时长t2,且所述第三时长t3大于第二时长t2,即负极性电压的充电时长不等于正极性电压的充电时长,且负极性电压的充电时长大于正极性电压的充电时长,以平衡正、负极性电压对相邻两列像素的充电效果,补偿正、负极性电压对相邻两列像素造成的充电差异,使得画面显示效果均匀。
步骤3、驱动所述列翻转模式的液晶显示面板进行下一帧画面的显示。
请结合图5与图7,仍以所述奇数列像素内的充电控制薄膜晶体管T2’为P型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为N型薄膜晶体管为例,对于第N行像素,第N条扫描线向第N行像素的驱动薄膜晶体管T1的栅极提供时长为第一时长t1的扫描信号GATE(N),所述时钟信号CK先提供时长为第三时长t3的高电位控制第N行偶数列像素内的充电控制薄膜晶体管T2打开,于此同时,相应的数据线S(M)提供负极性电压,使得第N行偶数列像素内的驱动薄膜晶体管T1的源极电压为负极性,对第N行偶数列像素进行充电;之后,所述时钟信号CK再提供时长为第二时长t2的低电位控制第N行奇数列像素内的充电控制薄膜晶体管T2打开,于此同时,相应的数据线S(M)提供正极性电压,使得第N行奇数列像素内的驱动薄膜晶体管T1的源极电压为正极性,对第N行奇数列像素进行充电。
按同样方式依次逐行扫描,直至完成对所述下一帧画面的驱动。
进一步地,如图3、图4所示,列翻转模式的液晶显示面板中,每相邻两列像素的极性相反,每相邻两帧之间同一像素的极性相反,因此在该步骤3中需要设置时钟信号CK的高电位的时长为第三时长t3,低电位时长为第二时长t2,以保证负极性电压的充电时长始终为第四时长t3,正极性电压的充电时长始终为第二时长t2。依据数据线提供的电压的正、负极性不同,通过调整提供给充电控制薄膜晶体管T2栅极的时钟信号CK的电位高低及脉冲宽度,控制正、负极性电压分别对相邻两列像素进行充电的时间,能够平衡正、负极性电压对相邻两列像素的充电效果,补偿正、负极性电压对相邻两列像素造成的充电差异,使得画面显示效果均匀。
步骤4、步骤2、3交替循环,驱动所述列翻转模式的液晶显示面板连续进行画面显示。
值得一提的是,当所述奇数列像素内的充电控制薄膜晶体管T2’为N型薄膜晶体管,所述偶数列像素内的充电控制薄膜晶体管T2为P型薄膜晶体管时,所述步骤2与步骤3相应的先对奇数列像素进行充电,再对偶数列像素进行充电,其余过程相同,此处不再赘述。
上述方法能够完成对列翻转模式的液晶显示面板的驱动,且不会因正负、极性电压不同影响像素的充电效果,保证画面显示均匀。
综上所述,本发明的列翻转模式的液晶显示面板及其驱动方法,通过在像素驱动电路中增加充电控制薄膜晶体管,并依据数据线提供的电压的正、负极性不同,调整提供给充电控制薄膜晶体管栅极的时钟信号的电位高低及脉冲宽度,控制正、负极性电压分别对相邻两列像素进行充电的时间,能够平衡正、负极性电压对相邻两列像素的充电效果,补偿正、负极性电压对相邻两列像素造成的充电差异,使得画面显示效果均匀。
以上所述,对于本领域的普通技术人员来说,可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形,而所有这些改变和变形都应属于本发明权利要求的保护范围。
