Description

三维液晶显示器以及其相关驱动方式 技术领域
本发明涉及液晶显示器与其相关驱动方式，尤其涉及一种三维液晶显示器以及其相关驱动方式。
 背景技术
液晶显示器具有轻、薄、低耗电等优点，被广泛应用于计算机、移动电话及个人数字助理等现代化信息设备。一般液晶显示器主要由一液晶显示面板与一背光模块组装而成，而液晶显示面板主要包括阵列基板、彩膜基板及夹于两基板之间的液晶层。其中，阵列基板包括由像素阵列组成的像素区。
由于人们对于影像显示的要求日益增加，因此，能够显示三维立体影像的三维(3D)液晶显示器渐渐成为液晶显示器的一个主流。其中，快门式眼镜三维液晶显示器(shutter glasses 3D display)显示三维影像的基本原理，是利用液晶显示器在1/60秒内显示左眼画面与右眼画面，再搭配快门式眼镜进行开关，使得左眼仅能看到左眼画面，右眼仅能看到右眼画面，藉由视觉暂留以及双眼视差的原理，使影像在用户脑中合成出一个三维的立体影像。
一般来说，三维显示器可分为扫描频率120Hz的显示器，保持式240Hz的显示器，以及插黑式240Hz的显示器。请参阅图1，图1绘示了现有三种三维显示器的基本驱动方式。如图1所示，扫描频率120Hz的显示器的左眼画面与右眼画面皆以120Hz的频率交错显示。扫描频率240Hz的保持式显示器的左眼画面与右眼画面以240Hz的频率显示，且左眼画面与右眼画面皆重复显示一次。扫描频率240Hz的插黑式显示器的左眼画面与右眼画面亦以240Hz的频率显示，且左眼画面与右眼画面中间插入一个黑画面。
如业界所习知，业界一般利用“窜扰”(crosstalk)指数，来评估三维显示器画面三维效果，其“窜扰”的定义由下列方程式(1)表示：
crosstalk = [L(WB)-L(BB)]/[L(BW)-L(BB)] (1)
方程式(1)所代表的意义为，透过右眼镜片，量测显示器画面(左眼画面为白画面，右眼画面为黑画面时)的亮度L(WB)，减去左右眼画面都是黑画面时的亮度L(BB)，除以量测显示器画面(左眼画面为黑画面，右眼画面为白画面时)的亮度L(BW)，减去左右眼画面都是黑画面时的亮度L(BB)。
其中，窜扰值越小，代表越不容易透过右眼镜片，看到属于左眼镜片的影像，这样的三维效果较佳。
因此，业界皆致力于开发出窜扰较小，三维效果较佳的三维显示器技术。
 技术问题
本发明所要解决的技术问题在于，提供一种三维液晶显示器与其驱动方式，可以有效地降低窜扰，进而提升三维显示器的三维显示效果。
 技术解决方案
本发明提供了一种三维液晶显示器的驱动方式，用来驱动一三维液晶显示器，所述三维液晶显示器包括相互交叉排列的N条数据线和2M条扫描线，所述驱动方式包含：于一第一扫描时间中，以每次开启所述2M条扫描线的两相邻扫描线的方式，循序扫描所述2M条扫描线，并同时将对应一第一画面的数据输出至所述N条数据线；以及于一第二扫描时间中，循序开启所述2M条扫描线的偶数条扫描线，并同时将对应一第二画面的数据输出至所述N条数据线；其中，所述第一画面用来给使用者的一眼观看，而所述第二画面用来给使用者的另一眼观看。
其中，所述第一扫描时间等于所述第二扫描时间。
或者，所述第一扫描时间等于1/240秒。
或者，所述第二扫描时间等于1/240秒。
进一步地，所述第一扫描时间与所述第二扫描时间相邻。
本发明还提供了一种三维液晶显示器，所述三维液晶显示器包括相互交叉排列的N条数据线和2M条扫描线，所述三维液晶显示器另包含：一栅极驱动模块，于一第一扫描时间中，以每次开启所述2M条扫描线的两相邻扫描线的方式，循序扫描所述2M条扫描线，以及于一第二扫描时间中，循序开启所述2M条扫描线的偶数条扫描线；以及一源极驱动模块，耦接至所述N条数据线，用来于所述第一扫描时间将对应一第一画面的数据输出至所述N条数据线，以及用来于所述第二扫描时间，将对应一第二画面的数据输出至所述N条数据线；其中，所述第一画面用来给使用者的一眼观看，而所述第二画面用来给使用者的另一眼观看。
其中，所述第一扫描时间等于所述第二扫描时间。
或者，所述第一扫描时间等于1/240秒。
或者，所述第二扫描时间等于1/240秒。
进一步地，所述第一扫描时间与所述第二扫描时间相邻。
 有益效果
由于本发明对于两个扫描线仅进行一次扫描，因此等效上仅须一半的时间便能完成整个画面的扫描，所以，当本发明采用120Hz的扫描频率驱动时，完成一个画面的时间仅有1/240秒，降低了扫描时间，因此，本发明的三维显示器可以降低窜扰，提升三维画面的显示质量。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在此请先参阅图2，图2绘示了一液晶显示面板200。液晶显示面板200用120Hz扫描频率进行扫描，其中区域210、区域220、区域230分别代表液晶显示面板200的上、中、下各区域。图中的箭头方向代表液晶显示面板200的扫描方向，一般来说，液晶显示面板200是由上向下进行扫描。
在此请参阅图3，图3绘示了液晶显示面板200以120Hz的扫描频率进行扫描时，各区域210、区域220、区域230的液晶穿透率与时间的关系，其中，线段211代表区域210的透光率，线段221代表区域220的透光率，而线段231代表区域230的透光率。如图3所示，当液晶显示面板200以120Hz的扫描频率进行扫描时，由于扫描线从上到下的扫描时间较长，因此在同一时间，液晶显示面板200上、中、下各区域210、220、230的液晶穿透率相差较大。在白画面时，以两区的背光为例，当上半部背光打开时，液晶显示面板200上半部(区域210)的穿透率较高，而下半部(区域230)穿透率较低，因此上半部(区域210)较亮而下半部(区域230)较暗；反之亦然，当下半部背光打开时，液晶显示面板200的下半部(区域230)穿透率较高，而上半部(区域210)穿透率较低，因此下半部(区域230)较亮而上半部(区域210)较暗。另一方面，在黑画面时，当上半部背光打开时，液晶显示面板200的上半部(区域210)穿透率较低，而下半部(区域230)穿透率较高，因此下半部(区域230)较亮而上半部(区域210)较暗；反之亦然。
因此，在此请参阅图4，图4为液晶显示面板200垂直方向的窜扰曲线图。如图4所示，在液晶显示面板200垂直方向的窜扰分布，位于面板中间(对应区域220)的窜扰最低，而上下两侧(对应区域210与区域230)的窜扰相对较高。
另一方面，在此请参阅图5，图5绘示另一液晶显示面板500。液晶显示面板500用240Hz扫描频率进行扫描，其中区域510、区域520、区域530亦分别代表液晶显示面板500的上、中、下各区域，图中的箭头方向代表液晶显示面板500的扫描方向，一般来说，液晶显示面板500是由上向下进行扫描。
在此请参阅图6，图6绘示了液晶显示面板500以240Hz的扫描频率进行扫描时，各区域510、区域520、区域530的液晶穿透率与时间的关系，其中，线段511代表区域510的透光率，线段521代表区域520的透光率，而线段531代表区域530的透光率。在此请注意，当液晶显示面板500采用240Hz的扫描频率进行驱动时，由于扫描线从上到下的时间较短，因此在同一时间，液晶显示面板500上、中、下各区域510、520、530相差较小。在白画面时，以两区的背光为例，当上半部背光打开时，液晶显示面板500上半部(区域510)的穿透率较高，而下半部(区域530)穿透率虽然亦较低，但相对于120Hz的面板200，与上半部(区域510)的差距较小，因此上半部(区域510)与下半部(区域530)的亮度相差不大；反之亦然，当下半部背光打开时，上下半部的亮度差异不大。
另一方面，在黑画面时，当上半部背光打开时，液晶显示面板500的上半部(区域510)与下半部(区域530)穿透率皆低，彼此间的亮度相差不大；反之亦然，当下半部背光打开时，上半部(区域510)与下半部(区域530)穿透率皆低，彼此间的亮度相差不大。
在此请参阅图7，图7为液晶显示面板500垂直方向的窜扰曲线图。如图7所示，在液晶显示面板500垂直方向的窜扰分布与液晶显示面板200类似，位于面板中间(对应区域520)的窜扰最低，而上下两侧(对应区域510与区域530)的窜扰相对较高；但是，在此请注意，比较图4与图7，可以得知液晶显示面板500的窜扰相较于液晶显示面板200，其窜扰相对较低，且面板500上下两侧与中间的窜扰差距也相对较小。
本发明便是利用这种性质，来降低液晶显示面板的窜扰。
在此请参阅图8，图8为本发明三维液晶显示器800一实施例的示意图。如图8所示，三维液晶显示器800包含有栅极驱动模块810、数据驱动模块820以及液晶显示面板830。液晶显示面板830包含有相互交叉排列的N条数据线(D1~DN)和2M条扫描线(G1~G2M)，栅极驱动模块810耦接至扫描线G1~GM，用来驱动液晶显示面板830的扫描线，而数据驱动模块820则耦接至数据线D1~DN，用来将欲显示的数据输出至数据线D1~DN。
在此请继续参阅图9，图9为三维液晶显示器800的驱动示意图。如图9所示，本发明的扫描分为两个扫描时间：第一扫描时间T1与第二扫描时间T2。在此请注意，于本实施例中，第一扫描时间T1与第二扫描时间T2彼此相邻，对应1/240秒。
由于三维液晶显示器800必须交错的显示左眼画面与右眼画面，本发明便是利用第一扫描时间T1来显示其中的一个画面(譬如前述的左眼画面)，而利用第二扫描时间T2来显示另外一个画面(譬如前述的右眼画面)。
本发明的操作如下：
在第一扫描时间T1时，栅极驱动模块810以一次扫描两条相邻扫描线的方式，对液晶显示面板830进行扫描，而此时数据驱动模块820则将对应一个画面(譬如前述的左眼画面)的数据输出至数据线D1~DN。于本实施例中，栅极驱动模块810的驱动方式可如图9所示，第一次驱动扫描线G1与G2，第二次则驱动扫描线G3与G4，如此以两条邻近扫描线为单位来进行扫描的方式，依序对所有扫描线G1~G2M进行扫描， 而在此同时，数据驱动模块820则将对应一个画面(譬如前述的左眼画面)的数据，输出至数据线D1~DN，以将整个画面(譬如前述的左眼画面)的数据显示于液晶显示面板830上。
之后，在第二扫描时间T1时，栅极驱动模块810仅扫描偶数条扫描线(G2、G4、G6……G2M)，以一次扫描一条扫描线的方式，对液晶显示面板830进行扫描；而此时数据驱动模块820则将对应另一画面(譬如前述的右眼画面)的数据输出至数据线D1~DN。于本实施例中，栅极驱动模块810的驱动方式可如图9所示，第一次驱动扫描线G2，第二次则驱动扫描线G4，以此类推，以仅扫描偶数条扫描线的方式来进行扫描，依序对所有偶数扫描线G2、G4、G6……G2M进行扫描， 而在此同时，数据驱动模块820则将对应另一画面(譬如前述的右眼画面)的数据，输出至数据线D1~DN，以将整个画面(譬如前述的右眼画面)的数据显示于液晶显示面板830上。
在此请注意，由于本发明三维液晶显示器800在进行扫描时，其扫描方式是一次扫描两条扫描线，或仅扫描全部扫描线的一半扫描线，因此，三维液晶显示器800进行扫描的时间仅须本来的一半。于本实施例中，三维液晶显示器800扫描第一个画面(左眼画面)或第二个画面(右眼画面)仅须1/240秒，这样的作动方式类似于前述的240Hz驱动方式，因此，液晶显示面板830各区域的穿透率较相近，其窜扰数与均匀性都比120Hz的面板来得好。
在此请注意，虽然于前述的实施例中，液晶显示器800是先输出左眼画面，之后输出右眼画面，然而，这样的顺序仅为一实施例，而非本发明的限制；在实作上，亦可先输出右眼画面，在输出左眼画面，如此的相对应变化，亦不违背本发明的精神。
相较于现有技术，本发明液晶显示器800可具有较小的窜扰，并具有较佳的均匀性，进而提升了三维画面的输出质量。
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。
