Description

显示装置的驱动方法 技术领域
本发明涉及显示装置技术领域，特别涉及一种显示装置的驱动方法。
 背景技术
请参阅图1，其为现有的显示装置10，显示装置10包括若干条扫描线100(又称为闸极线)、若干条数据线102(又称为源极线)以及若干个画素104，每个画素104由一条对应的扫描线100控制导通或不导通并由一条对应的数据线102提供数据。
传统显示装置10的驱动方法是从上往下依序导通一条扫描线100，再由数据线102将数据写入导通的扫描线100所控制的画素104，也就是说，传统的驱动方法是一次导通一条扫描线100，最后一条扫描线100导通之后，再从第一条扫描线100依序驱动。
为了加快显示装置10显示画面的速度，目前有一种驱动方法同时导通两条扫描线100，再由数据线102将数据写入导通的扫描线100所控制的画素104，更明确地说，首先同时导通第一条扫描线100与最后一条扫描线100，第一条扫描线100控制的画素104与最后一条扫描线100控制的画素104由两个不同的源极驱动电路(未图示)提供数据，然后使第一条扫描线100与最后一条扫描线100不导通，接着同时导通第二条扫描线100与倒数第二条扫描线100，第二条扫描线100控制的画素104与倒数第二条扫描线100控制的画素104由上述两个不同的源极驱动电路(未图示)提供数据，依此类推。简而言之，上述驱动方法是同时从显示装置10上下的扫描线100往中间导通，由于上半区域的画素104与下半区域的画素104是由不同的源极驱动电路(未图标)提供数据，而不同的源极驱动电路所输出的电压会有压差，因此如图2所示，上半区域与下半区域的交界处会产生交界线110，更明确地说，上半区域与下半区域的亮度不同，亦即发生亮度不均匀的现象(mura)，导致显示装置10的显示品质不佳。
因此，需要对上述不同的源极驱动电路提供数据而导致上半区域与下半区域的亮度不同的问题提出解决方法。

图4为根据本发明较佳实施例的显示装置的驱动方法流程图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。
请参阅图3，其为根据本发明较佳实施例的显示装置的驱动方法的示意图。
显示装置30包括若干条扫描线G1-G8、若干条与扫描线G1-G8绝缘相交的数据线S1-S6、若干个由扫描线G1-G8与数据线S1-S6定义的画素304、第一源极驱动电路310以及第二源极驱动电路320，每个画素304由扫描线G1-G8的其中一条控制导通或不导通，并由数据线S1-S6的其中一条提供数据。
扫描线G1-G8从上至下依序位于一第一区域A1、一中间区域M以及一第二区域A2，于本实施例中，扫描线G1-G2位于第一区域A1，扫描线G3-G6位于中间区域M，扫描线G7-G8位于第二区域A2。中间区域M是现有技术中容易产生交界线的区域。
要说明的是，为了便于说明，本实施例的第一区域A1与第二区域A2各包括两条扫描线，而中间区域M包括四条扫描线，实际情况中，第一区域A1与第二区域A2所包括的扫描线数量是远大于中间区域M所包括的扫描线数量。
各数据线S1-S6被分成两条电性断接的线段，较佳而言，各数据线S1-S6在第一区域A1与中间区域M交界处的位置、中间区域M与第一区域A2交界处的位置、或是在中间区域M其中两条扫描线之间的位置被分成两条电性断接的线段，且数据线S1-S6的至少一条被分成两条电性断接的线段的位置与其它不同。
于本实施例中，相邻数据线被分成两条电性断接的线段的位置不同。数据线S1是在扫描线G3与扫描线G4之间的位置(中间区域M其中两条扫描线之间的位置)被分成两条电性断接的线段，数据线S2是在扫描线G5与扫描线G6之间的位置(中间区域M其中两条扫描线之间的位置)被分成两条电性断接的线段，数据线S3是在扫描线G2与扫描线G3之间的位置(第一区域A1与中间区域M交界处的位置)被分成两条电性断接的线段，数据线S4是在扫描线G5与扫描线G6之间的位置(中间区域M其中两条扫描线之间的位置)被分成两条电性断接的线段，数据线S5是在扫描线G3与扫描线G4之间的位置(中间区域M其中两条扫描线之间的位置)被分成两条电性断接的线段，数据线S6是在扫描线G5与扫描线G6之间的位置(中间区域M其中两条扫描线之间的位置)被分成两条电性断接的线段。
首先，于一第一期间，同时导通第一区域A1沿着一第一方向D1的第一条扫描线G1与第二区域沿着一第二方向D2(与第一方向D1相反)的第一条扫描线G8，第一源极驱动电路310沿着第一方向D1经由数据线S1-S6上方线段提供数据给电性连接至扫描线G1的画素304，第二源极驱动电路320沿着第二方向D2经由数据线S1-S6下方线段提供数据给电性连接至扫描线G8的画素304。然后，使第一区域A1的扫描线G1与第二区域的扫描线G8不导通。
于一第二期间，同时导通第一区域A1的扫描线G2与第二区域的扫描线G7，第一源极驱动电路310经由数据线S1-S6上方线段提供数据给电性连接至扫描线G2的画素304，第二源极驱动电路320经由数据线S1-S6下方线段提供数据给电性连接至扫描线G7的画素304。然后，使第一区域A1的扫描线G2与第二区域的扫描线G7不导通。
于一第三期间，扫描中间区域M时，只导通一条扫描线，亦即扫描线G3，由于数据线S3是在扫描线G2与G3之间被分成两条电性断接的线段，所以第二源极驱动电路320经由数据线S3下方线段提供数据给电性连接至扫描线G3的画素304，第一源极驱动电路310经由数据线S1、S2、S4、S5、S6上方线段提供数据给电性连接至扫描线G3的画素304。然后，使中间区域M的扫描线G3不导通。
于一第四期间，只导通中间区域M的扫描线G4，第一源极驱动电路310经由数据线S2、S4、S6上方线段提供数据给电性连接至扫描线G4的画素304，第二源极驱动电路320经由数据线S1、S3、S5下方线段提供数据给电性连接至扫描线G4的画素304。然后，使中间区域M的扫描线G4不导通。
于一第五期间，只导通中间区域M的扫描线G5，第一源极驱动电路310经由数据线S2、S4、S6上方线段提供数据给电性连接至扫描线G5的画素304，第二源极驱动电路320经由数据线S1、S3、S5下方线段提供数据给电性连接至扫描线G5的画素304。然后，使中间区域M的扫描线G5不导通。
于一第六期间，只导通中间区域M的扫描线G6，由于数据线S1-S6都在扫描线G6上方被分成两条电性断接的线段，第一源极驱动电路310无法经由数据线S1-S6上方线段提供数据给电性连接至扫描线G6的画素304，因此由第二源极驱动电路320经由数据线S1-S6下方线段提供数据给电性连接至扫描线G6的画素304。然后，使中间区域M的扫描线G6不导通。
从图3的实施例可知，本发明之显示装置的驱动方法在扫描第一区域A1与第二区域A2时，与现有技术同样一次同时导通两条扫描线，包括第一区域A1与第二区域A2各一条，且第一区域A1的画素304由第一源极驱动电路310提供数据，第二区域A2的画素304由第二源极驱动电路320提供数据，在扫描中间区域M时，则一次只导通一条扫描线，且在中间区域M中各数据线S1-S6根据被分成两条电性断接的线段的位置由第一源极驱动电路310或第二源极驱动电路320提供数据。
要说明的是，图3的实施例中第一区域A1与第二区域A2是从两相反方向D1、D2开始扫描，于另一实施例中，可以不用根据两相反方向D1、D2而选择第一区域A1的任意一条扫描线与第二区域A2的任意一条扫描线同时导通即可(如图4的流程图所述)。
请参阅图4，其为根据本发明较佳实施例的显示装置的驱动方法流程图。所述显示装置包括若干条扫描线、若干条与扫描线相交的数据线、若干个由扫描线与数据线定义的画素、一第一源极驱动电路以及一第二源极驱动电路，这些扫描线依序位于一第一区域、一中间区域以及一第二区域，各数据线被分成两条电性断接的线段。
于一实施例中，各数据线在第一区域与中间区域交界处的位置、中间区域与第一区域交界处的位置、或是在中间区域其中两条扫描线之间的位置被分成两条电性断接的线段。
较佳而言，这些数据线的至少一条被分成两条电性断接的线段的位置与其它数据线被分成两条电性断接的线段的位置不同。更佳而言，相邻数据线被分成两条电性断接的线段的位置不同。
步骤S400中，同时导通第一区域的一条扫描线与第二区域的一条扫描线。
步骤S410中，第一源极驱动电路经由这些数据线的其中一线段提供数据给电性连接至第一区域被导通的扫描线的画素，第二源极驱动电路经由这些数据线的其中另一线段提供数据给电性连接至第二区域被导通的扫描线的画素。
步骤S420中，扫描完第一区域与第二区域所有的扫描线之后，导通中间区域的一条扫描线。
步骤S430中，根据各数据线被分成两条电性断接的线段的位置由第一源极驱动电路或第二源极驱动电路提供数据。
本发明之显示装置的驱动方法在显示装置的上下区域(即第一区域与第二区域)一次导通两条扫描线，在中间区域只导通一条扫描线，由于上下区域的扫描线数量远大于中间区域的扫描线数量，因此驱动时大部分的时间仍是同时导通两条扫描线，因此能保留现有技术加快显示装置显示画面的速度，中间区域只导通一条扫描线，降低中间区域的亮度差异而使人眼无法察觉，因此能改善现有技术产生交界线的问题，亦即能避免亮度不均匀的现象(mura)发生。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
