下面结合附图,对本公开实施例提供的阵列基板及液晶显示面板进行具体说明。
本公开实施例提供的一种阵列基板,如图1所示,阵列基板包括矩阵排列的多个像素电极01以及与个像素电极01连接的像素晶体管02,多条扫描线G1以及多条数据线D1;其中,像素晶体管02的栅极023与扫描线G1连接,像素晶体管02的第一电极021与像素电极01连接,像素晶体管02的第二电极022与数据线D1连接;
如图2至图5所示,像素晶体管02还包括:与扫描线G1连接的补偿栅极024以及与第一电极021连接的补偿电极025;
补偿电极025与第一电极021沿扫描线G1的延伸方向并排设置;
补偿栅极024与栅极023沿扫描线G1的延伸方向并排且间隔设置;
补偿栅极024与补偿电极025位于栅极023同一侧。
本公开实施例提供的阵列基板,由于像素晶体管中还包括与扫描线G1连接的补偿栅极024以及与第一电极021连接的补偿电极025;补偿电极025与第一电极021沿扫描线G1的延伸方向并排设置;补偿栅极024与栅极023沿扫描线G1的延伸方向并排且间隔设置;补偿栅极024与补偿电极025位于栅极023同一侧。在制备阵列基板时,如图3所示,当栅极023在沿扫描线G1方向发生对位误差时,虽然栅极023与第一电极021和第二电极022的重叠面积变小,但是由于对位偏移使补偿栅极024与补偿电极025重叠,从而利用补偿栅极024与补偿电极025的重叠面积来补偿因对位偏移而导致的栅极 023与第一电极021和第二电极022的重叠面积的变小,避免因为栅极023与第一电极021和第二电极022重叠面板发生变化而引起的Cgs、Ioff等性能的变动,从而稳定像素晶体管的性能。
在具体实施时,本公开实施例提供的阵列基板中,像素晶体管可以是薄膜晶体管(TFT,Thin Film Transistor),也可以是金属氧化物半导体场效应管(MOS,Metal Oxide Semiconductor),在此不做限定。
在本公开实施例中,像素晶体管的第一电极可以为源极,第二电极可以为漏极,或者,像素晶体管的第一电极可以为漏极,第二电极可以为源极,在此不作具体区分。
可选地,在本公开实施例提供的阵列基板中,如图2和图4所示,补偿电极025与第一电极021为一体结构,这样可以不用增加新的构工艺,从而避免增加生产成本。
可选地,在本公开实施例提供的阵列基板中,如图2和图5所示,补偿栅极024与栅极023同层设置,这样可以不用增加新的构工艺,从而避免增加生产成本。
可选地,在本公开实施例提供的阵列基板中,如图4和图5所示,补偿栅极024与栅极023沿扫描线G1方向的距离s2小于补偿电极025沿扫描线G1方向的宽度s1。
可选地,在本公开实施例提供的阵列基板中,如图2所示,补偿栅极024与补偿电极025在阵列基板的正投影至少部分重叠。具体地,如图2所示,当栅极023与第一电极021和第二电极022对位无偏差时,补偿栅极024和补偿电极025的重叠面积较小从而不影响像素晶体管的性能。如图3所示,当栅极023在沿扫描线G1方向发生对位误差时,虽然栅极023与第一电极021和第二电极022的重叠面积变小,但是补偿栅极024与补偿电极025的交叠面积变大,从而可以保证避免因为栅极023与第一电极重叠面板发生变化而引起的Cgs、Ioff等性能的变动,从而稳定像素晶体管的性能。
可选地,在本公开实施例提供的阵列基板中,补偿栅极与补偿电极在阵 列基板的正投影的重叠面积为第一面积,栅极与第一电极在阵列基板的正投影的重叠面积为第二面积;
第一面积与第二面积之和大于第一电极的面积且小于或等于第一电极的面积的1.3倍。
即保证当栅极与第一电极沿扫描线方向的对位偏移在一定范围内时,第一面积与第二面积之和始终在一定范围内,避免第一面积与第二面积之和发生太大波动。
在具体实施时,例如第一电极的面积为A1,第一面积和第二面积之和可以为1.05A1,1.1A1、1.15A1、1.2A1、1.25A1或1.3A1等。
可选地,在本公开实施例提供的阵列基板中,如图2和图4所示,补偿电极025包括沿扫描线G1延伸方向延伸的条形部0251;
第一电极021通过条形部0251与像素电极01电连接。
即利用第一电极021与像素电极01之间的间隙设置补偿电极025,尽可能的减小对像素开口率的影响。
可选地,在本公开实施例提供的阵列基板中,如图6至图8所示,补偿电极025还包括位于条形部0251靠近像素电极01一侧且沿数据线D1延伸方向突出的突出部0252;
如图5和图8所示,条形部0251沿数据线D1延伸方向的宽度w1小于补偿栅极024沿数据线D1延伸方向的宽度w0;
突出部0252和条形部0251沿数据线D1延伸方向的宽度w2大于或等于补偿栅极024沿数据线D1延伸方向的宽度w0。
在具体实施时,当栅极023与第一电极021和第二电极022对位无偏差时,补偿电极025的突出部0252位于栅极023与补偿栅极024之间。即利用突出部0252增加补偿电极025的面积可以保证当栅极023与第一电极021对位发生偏移时,增大补偿电极025与补偿栅极024的重叠面积。而当栅极023与第一电极021和第二电极022对位无偏差时,补偿电极025的突出部0252位于栅极023与补偿栅极024之间,可以保证当栅极023与第一电极021和 第二电极022对位无偏差时,补偿栅极024与突出部0252不重叠。
可选地,在本公开实施例提供的阵列基板中,如图2、图5和图6所示,补偿栅极024的面积小于栅极023的面积,从而避免补偿栅极024面积太大影响阵列基板的整体开口率。
在具体实施时,在本公开实施例提供的阵列基板中,如图1所示,每行像素电极01分别对应一条扫描线G1,每一列像素电极01分别对应一条数据线D1。
可选地,在本公开实施例提供的阵列基板中,如图9所示,每行像素电极01的两侧分别设置有一条扫描线G1,且相邻两行像素电极01之间设置有两条扫描线G1;
位于同一行相邻的两个像素电极01共用同一数据线D1。即阵列基板为双栅结构,这样可以减少一半数据线D1,从而有利于提高显示面板的分辨率。
进一步地,在本公开实施例提供的阵列基板中,如图10所示,数据线D1沿列方向呈“弓”字型曲折延伸。
基于同一发明构思,本公开实施例还提供了一种液晶显示面板,包括相对设置的阵列基板和对向基板,以及位于阵列基板和对向基板之间的液晶层;其中,该阵列基板为本发明实施例提供的上述任一种阵列基板。由于该液晶显示面板解决问题的原理与前述一种阵列基板相似,因此该液晶显示面板的实施可以参见前述阵列基板的实施,重复之处不再赘述。
本公开实施例提供的一种阵列基板及液晶显示面板,由于像素晶体管中还包括与扫描线连接的补偿栅极以及与第一电极连接的补偿电极;补偿电极与第一电极沿扫描线的延伸方向并排设置;补偿栅极与栅极沿扫描线的延伸方向并排且间隔设置;补偿栅极与补偿电极位于栅极同一侧。在制备阵列基板时,当栅极在沿扫描线方向发生对位误差时,虽然栅极与第一电极和第二电极的重叠面积变小,但是由于对位偏移使补偿栅极与补偿电极重叠,从而利用补偿栅极与补偿电极的重叠面积来补偿因对位偏移而导致的栅极与第一电极和第二电极的重叠面积的变小,避免因为栅极与第一电极和第二电极重 叠面板发生变化而引起的Cgs、Ioff等性能的变动,从而稳定像素晶体管的性能。
显然,本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样,倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内,则本公开也意图包含这些改动和变型在内。
