Description

薄膜晶体管矩阵结构及液晶显示面板 技术领域
本专利申请涉及一种晶体管矩阵结构及其显示面板,且特别是涉及一种薄膜晶体管矩阵结构及液晶显示面板。
背景技术
薄膜晶体管矩阵结构(Thin-Film Transistor Array, TFT Array)是液晶显示器(Liquid Crystal Display, LCD)不可或缺的重要显示组件,图1是现有技术的薄膜晶体管矩阵结构100的结构示意图。其中薄膜晶体管矩阵结构100主要是由若干个像素单元(pixel unit)102、若干条扫描线(scan line)104以及若干条数据线(data line)106所组成。
这些像素单元102电性连接这些扫描线104与数据线106,每一像素单元102具有一晶体管108、液晶电容(liquid-crystal capacitor, CLC)110以及储存电容(storage capacitor, CS) 112,其中每一晶体管108具有一闸极(gate)G、一源极(source)S以及一汲极(drain)D,而闸极G连接扫描线104,源极S连接数据线106,且汲极D共同连接液晶电容(CLC)110以及储存电容(CS)112,所述液晶电容(CLC)110以及储存电容(CS)112接地(如图1所示)或是共同连接至共享线(common line)(未图示)。
当第一扫描线(SL1)上施加足够大的正电压时,连接所述第一扫描线(SL1)上的薄膜晶体管108会被开启(switch on),使这些液晶电容的像素电极与垂直方向的资料线106电性导通,而经由垂直数据线送入对应的视频信号,以将这些液晶电容充电至适当的电压水平;换言之,对这些像素单元所对应的液晶电容进行充电,以驱动液晶层内的液晶分子,使液晶显示器显示影像;同时,对连接所述数据线的这些储存电容112进行充电,所述储存电容112在于使液晶电容110两端的电压维持在一定值下,亦即在未进行数据更新之前,液晶电容110的两端电压藉由储存电容112维持住。接着,施加足够大的负电压,关闭(switch off)薄膜晶体管108,直到下次再重新写入视频信号,其间使得电荷保存在液晶电容110上,此时再启动次一条水平扫描线(SL2)104,而经由垂直数据线106送入其对应的视频信号。
然而,必须在目前扫描线(SL1)上的薄膜晶体管108关闭之后,才能对次扫描线(SL2)的像素单元(P2)的液晶电容110以及储存电容充电,耗费较长的充电时间。因此需要发展一种新式的薄膜晶体管矩阵结构,以解决上述充电时间过长的问题。

参考图2,其为根据本专利申请实施例中薄膜晶体管矩阵结构200的示意图。所述薄膜晶体管矩阵结构200包括若干扫描线202、若干第一数据线204a、若干第二数据线204b、若干像素单元206以及若干控制模块208。若干扫描线202分别与若干第一数据线204a及若干第二数据线204b互相交错排列设置。此处是以两条扫描线SL(n-1)、SLn 202与一条第一资料线DL1 204a、一条第二资料线DL2 204b交错排列设置,两个像素单元P(n-1)、Pn 206,以及两个控制模块CT(n-1)、CTn 208为例作说明,但是其数量不限于此。
每一像素单元P(n-1)、Pn 206分别耦接于一扫描线202、一第一数据线204a以及控制模块208之间,所述若干像素单元P(n-1)、Pn 206分别设置于两条扫描线SL(n-1)、SLn 202与一条第一资料线DL1 204a及一条第二资料线DL2 204b交错位置附近。
若干控制模块208a、208b设置于像素单元P(n-1)、Pn 206之间。其中一控制模块208a耦接于一扫描线SL(n-1) 202、一第二数据线204b以及一像素单元P(n-1) 206之间;另一控制模块208b耦接于另一扫描线SLn 202、一第二数据线204b以及另一像素单元Pn 206之间。当开启一扫描线SL(n-1) 202以使第一资料线DL1 204a对所述像素单元P(n-1) 206充电时,通过所述第二数据线DL2 204b以对下级控制模块208b作充电,当关闭所述扫描线SL(n-1) 202且开启另一扫描线SLn 202以使所述第一资料线DL1 204a对另一像素单元Pn 206作充电时,所述充电的下级控制模块208b对所述另一像素单元Pn 206作充电。
所述下级控制模块208b还包括第一控制晶体管210a、第二控制晶体管210b以及电容器212。第一控制晶体管210a耦接于所述扫描线SL(n-1) 202、所述第二资料线DL2 204b、所述像素单元P(n-1) 206、以及一上级控制模块208a。第二控制晶体管210b耦接所述另一扫描线SLn 202以及所述另一像素单元Pn 206。电容器212耦接所述下级控制模块208b的所述第一控制晶体管210a以及第二控制晶体管210b。当开启一扫描线SL(n-1) 202以使所述第一资料线DL1 204a对所述像素单元P(n-1) 206充电时,通过所述第二数据线DL2 204b与所述下级控制模块208b的第一控制晶体管210a,以对下级控制模块208b的电容器212作充电,当关闭所述扫描线SL(n-1) 202并且开启另一扫描线SLn 202以使所述第一资料线DL1 204a对另一像素单元Pn 206充电时,所述充电的下级控制模块208b的电容器212对所述另一像素单元Pn 206充电。

根据上述,本专利申请之薄膜晶体管矩阵结构200运作时,在两个像素单元206之间利用两条数据线204a、204b,其中一条资料线204a用于对两个像素单元进行充电(亦即传送视频讯号),另一条数据线204b用于对电容器212预先充电。具体来说,施加一电压(例如正电压)至所述扫描线SL(n-1) 202,藉由开启像素单元P(n-1) 206的切换晶体管214,以对像素单元P(n-1) 206作充电,并且开启控制模块208a的第一控制晶体管210b,以使第二数据线DL 2 204b 传送视频信号,以通过下级控制模块208b的第一控制晶体管210a而对下级控制模块208b的电容器212预先进行充电。
接着,施加另一电压(例如负电压)至所述扫描线SL(n-1) 202,以关闭像素单元P(n-1) 206的切换晶体管214、上级控制模块208a的第二控制晶体管210b、以及下级控制模块208b的第一控制晶体管210a,亦即关闭与扫描线SL(n-1) 202连接的晶体管。然后,施加电压至所述另一扫描线SLn 202,藉由开启像素单元Pn 206的切换晶体管214,以对像素单元Pn 206作充电,同时通过下级控制模块208b的已充电电容器212对像素单元Pn 206作充电,如此可以节省像素单元Pn 206的充电时间,进行像素的快速充电。换言之,当切换晶体管214开启时,除了第一数据线DL1 204对像素单元Pn 206充电之外,可以进一步利用下级控制模块208b的已充电电容器212对像素单元Pn 206作充电,以达到快速充电的目的,有效缩短像素的充电时间。

所述薄膜晶体管矩阵结构200包括若干扫描线202、若干第一数据线204a、若干第二数据线204b、若干像素单元206以及若干控制模块208。若干扫描线202分别与若干第一数据线204a及若干第二数据线204b互相交错排列设置。此处是以两条扫描线SL(n-1)、SLn 202与一条第一资料线DL1 204a、一条第二资料线DL2 204b交错排列设置,两个像素单元P(n-1)、Pn 206,以及两个控制模块CT(n-1)、CTn 208为例作说明,但是其数量不限于此。
每一像素单元P(n-1)、Pn 206分别耦接于一扫描线202、一第一数据线204a以及控制模块208之间,所述若干像素单元P(n-1)、Pn 206分别设置于两条扫描线SL(n-1)、SLn 202与一条第一资料线DL1 204a及一条第二资料线DL2 204b交错位置附近。
