液晶显示装置及其驱动方法 技术领域
本发明是有关于一种液晶显示装置及其驱动方法，且特别是有关于一种能改变扫描顺序的液晶显示装置及其驱动方法。
 背景技术
液晶显示器(Liquid Crystal Display, LCD)因具有低辐射性以及轻薄短小的优点，所以在使用上日渐广泛，成为目前在市场上的主流显示器。
对于液晶分子的特性来说，由于液晶分子具有极性，如果液晶分子一直被固定在某一个极性电压下，液晶分子中的电荷可能被固定，而形成偶极矩（Dipole），当正负电荷固定在液晶分子两端时，将造成液晶的反应速度迟钝。因此，若要使液晶动作，必需以交流电方式驱动。液晶显示器的交流驱动方法通常可以分为四种：帧反转（Frame Inversion）、行反转（Row/Gate/Line Inversion）、列反转（Column/Data/Source Inversion）与点反转（Dot Inversion）。
在点反转的驱动模式中，为了减少成本以及提高制作液晶显示器的良率，目前提出采用一条数据线控制两列像素的控制方式。请参考图1，图1是现有技术的单条数据线控制两列像素的液晶显示面板线路示意图。其包括多条水平排列的扫描线G(n)、G(n+1)…，以及多条垂直排列的数据线D(n)、D(n+1)…，以及多个阵列排列的像素单元110。每一行所述的像素单元110交替的电性连接于两条扫描线G(n)及G(n+1)，每一条所述的数据线D(n)、D(n+1)…电性连接于左右两列像素单元110，且多个阵列排列的像素单元110的极性是呈点反转式分布。
虽然运用单条数据线控制两列像素虽有效减少了数据线的成本，但是在驱动过程中，所述扫描线G(n)、G(n+1) …依序被驱动，造成每一条数据线D(n)、D(n+1)…需频繁的提供不同极性的图像信号，例如由正到负、或由负到正如此交替。因此，提供数据线图像信号的数据芯片将消耗大量功率。
 技术问题
有鉴于此，本发明的目的在于提供一种通过开关控制扫描线驱动顺序的液晶显示装置。
本发明的另一目的在于提供一种驱动液晶显示装置的方法，其可利用一个较省电的扫描顺序去驱动扫描线，以降低数据芯片功率的消耗。
 技术解决方案
为达上述的目的，本发明提供了一种液晶显示装置，其包括若干个阵列排列的像素单元、若干条资料线、若干条第一扫描线及若干条第二扫描线，以及若干个开关单元。其中，每一行所述的像素单元中分为若干个第一像素单元及若干个第二像素单元。每一所述的资料线电性连接于每一行所述第一像素单元及所述第二像素单元，用于传输一图像信号；所述若干条第一扫描线与所述若干条第二扫描线互相平行排列设置，其中每一行所述的像素单元分别设置于所述第一扫描线及所述第二扫描线之间，并且所述若干个第一像素单元及所述若干个第二像素单元分别电性连接于所述第一扫描线及所述第二扫描线；所述若干个开关单元分别电性连接于所述若干条第一扫描线及所述若干条第二扫描线的一端，用于控制所述若干条第一扫描线及所述若干条第二扫描线的导通状态，以控制所述若干个第一像素单元及第二像素单元更新所述图像信号的顺序。
优选地，上述顺序为先更新所述若干个第一像素单元与所述若干个第二像素单元中的灰阶值变化总和的较小者。
所述液晶显示装置还包括一第一开关信号线及一第二开关信号线。所述第一开关信号线，通过所述若干个开关元件电性连接于每一所述的第一扫描线，其用于同时导通或断开所述若干条第一扫描线；所述第二开关信号线，通过所述若干个开关元件电性连接于每一所述的第二扫描线，其用于同时导通或断开所述若干条第二扫描线。
在本发明较佳实施例中，所述若干个开关元件是若干个薄膜晶体管，并且电性连接于所述第一开关信号线的若干个薄膜晶体管(Thin Film Transistor, TFT)是通过该若干个薄膜晶体管的栅极(Gate)端电性连接在一起；电性连接于所述第二开关信号线的若干个薄膜晶体管是通过该若干个薄膜晶体管的栅极端电性连接在一起。此外，所述液晶显示装置还包括一控制单元，所述控制单元电性连接于所述第一开关信号线及所述第二开关信号线的一端，用以输出一第一控制信号到所述第一开关信号线，以及输出一第二控制信号到所述第二开关信号线。所述第一控制信号及所述第二控制信号是用于控制对应的所述若干个开关元件的导通顺序，进而控制在每一行所述的像素单元中，先更新所述若干个第一像素单元或是先更新所述若干个第二像素单元。
为达上述的另一目的，本发明另提供一种驱动液晶显示装置的方法。该液晶显示装置包括若干个阵列排列的像素单元、若干条资料线、若干条第一扫描线及若干条第二扫描线，每一行所述的像素单元中分为若干个第一像素单元及若干个第二像素单元，每一所述的资料线电性连接于每一行所述第一像素单元及所述第二像素单元；若干条第一扫描线及若干条第二扫描线，所述若干个第一像素单元及所述若干个第二像素单元分别电性连接于所述第一扫描线及所述第二扫描线。所述方法包含：
(1)提供若干个开关单元分别电性连接于所述若干条第一扫描线及所述若干条第二扫描线的一端，以切换所述若干条第一扫描线及所述若干条第二扫描线的导通。
(2)计算所述若干条资料线先更新所述若干个第一像素单元的若干个灰阶值变化的总和，及计算先更新所述若干个第二像素单元的若干个灰阶值变化的总和。
(3) 根据两者总和的大小，选择每行像素单元的所述若干个第一像素单元及所述若干个第二像素单元更新的顺序并进行更新。
在本发明较佳实施例中，当先更新所述若干个第一像素单元的所述若干个灰阶值变化的总和大于先更新所述若干个第二像素单元的所述若干个灰阶值变化的总和时，所述若干个开关单元先导通第二扫描线以先更新所述若干个第二像素单元，而后导通第一扫描线以更新所述若干个第一像素单元。同样的，当先更新所述若干个第二像素单元的所述若干个灰阶值变化的总和大于先更新所述若干个第一像素单元的所述若干个灰阶值变化的总和时，所述若干个开关单元先导通第一扫描线以先更新所述若干个第一像素单元，而后导通第二扫描线以更新所述若干个第二像素单元。
根据本发明的液晶显示装置及其驱动方法，其在扫描线与一扫描芯片之间设置了开关元件，并通过控制所述若干个开关元件的导通，使得数据线更新所述若干个第一像素单元及所述若干个第二像素单元的顺序可被调整。此外，这些扫描线根据这些灰阶值变化的总和较小的顺序驱动这些扫描线，使得数据芯片的消耗功率可下降。
 有益效果
本发明的驱动液晶显示装置的方法可根据不同的画面（即图像信号）分析资料线跳变的灰阶变化较小的驱动路径而改变扫描线更新的顺序。由此可知，由灰阶变化较小的路径可以理解资料线跳变的电压差值也较少，因而可以降低数据芯片功率的消耗。

 本发明的最佳实施方式
请参照图2，图2是本发明较佳实施例的液晶显示装置的等效电路示意图。本较佳实施例的液晶显示装置200包含若干个阵列(Array)排列的像素单元110、若干条资料线220、若干条第一扫描线230及若干条第二扫描线240、若干个开关单元260及一控制单元300。其中每一行像素单元110中分为若干个第一像素单元1101及若干个第二像素单元1102。若干条资料线220中特以两条资料线220a及220b说明。
每一所述的资料线220电性连接于每一行所述的一第一像素单元1101及一第二像素单元1102。其中像素单元110的极性分别用“+”，“-”表示。每一资料线220所连接的第一像素单元1101及第二像素单元1102的极性皆为相同，且每一资料线220所连接的第一像素单元1101及第二像素单元1102之间设有一极性相反的像素单元110，以形成点反转的分布。其中每一条资料线220是通过两个薄膜晶体管(Thin Film Transistor, TFT)分别与第一像素单元1101及第二像素单元1102连接，为便于图示和说明，所述薄膜晶体管并未绘示于图中。在第N行的像素单元110中，第一像素单元1101设置于所连接的资料线220的左边，第二像素单元1102设置于所连接的资料线220的右边。需注意的是，在第N+1行的像素单元110中，第一像素单元1101设置于所连接的资料线220的右边，第二像素单元1102设置于所连接的资料线220的左边。所述第N+2行像素单元的排列和所述第N行像素单元的排列相同，同理第N+3行像素单元(未图示)的排列和所述第N+1行像素单元的排列相同，依次规律类推。每一条资料线220一端电性连接于一数据芯片（未图示），用于传输一图像信号以更新所述像素单元110。
所述若干条第一扫描线230与所述若干条第二扫描线240互相平行排列并间隔设置，其中每一行像素单元110分别设置于第一扫描线230及第二扫描线240之间，并且若干个第一像素单元1101及若干个第二像素单元1102分别电性连接于第一扫描线230及第二扫描线240。更具体的说，连接在每一条资料线220的第一像素单元1101和第二像素单元1102的栅极(Gate) (图未示)分别连接在所述第一扫描线230和所述第二扫描线240上，即，每一行像素单元110是通过两条扫描线（即第一扫描线230与第二扫描线240）所驱动。
对第N行的像素单元110而言，当第一扫描线230（特以第一扫描线2301表示）提供一个驱动信号（未图示）时，电性连接于资料线220a的第一像素单元1101、电性连接于资料线220b的第一像素单元1101等的薄膜晶体管的栅极（未图示）被导通，使得这些资料线220更新每一上述第一像素单元1101的图像信号。这些第一像素单元1101更新之后，接着第二扫描线240（特以第二扫描线2401表示）提供一个驱动信号，电性连接于资料线220a的第二像素单元1102、电性连接于资料线220b的第二像素单元1102等的薄膜晶体管的栅极被导通，使得这些资料线220更新每一第二像素单元1102的图像信号。承上所述，第N行的像素单元110被更新完成，随后更新第N+1行的像素单元110。
请再参照图2，所述若干个开关单元260分别电性连接于所述若干条第一扫描线230及所述若干条第二扫描线240的一端，用于控制所述若干条第一扫描线230及所述若干条第二扫描线240的导通状态。具体而言，所述液晶显示装置200还包括一第一开关信号线270及一第二开关信号线280。所述第一开关信号线270通过所述若干个开关元件260电性连接于每一所述的第一扫描线230，其用于同时导通及断开所述若干条第一扫描线230。同样的，所述第二开关信号线280通过所述若干个开关元件260电性连接于每一所述的第二扫描线240，其用于同时导通或断开所述若干条第二扫描线240。
举例来说，所述若干个开关元件260是若干个薄膜晶体管，并且电性连接于第一开关信号线270的所述若干个薄膜晶体管是通过若干个栅极端（未图示）电性连接在一起。同样的，电性连接于第二开关信号线280的所述若干个薄膜晶体管是通过若干个栅极端（未图示）电性连接在一起。
请参照图2及图3，图3是开关信号波形对应扫描信号以及第一及第二扫描线实际接收的波形图。所述控制单元300电性连接于第一开关信号线270及第二开关信号线280的一端，用以输出一第一控制信号20到第一开关信号线270，以及输出一第二控制信号40到第二开关信号线280，其中水平轴为时间。所述第一控制信号20及第二控制信号40是用于控制对应的所述若干个开关元件260的导通顺序，进而控制在每一行的像素单元110中，是先更新所述若干个第一像素单元1101或是先更新所述若干个第二像素单元1102。
举第N行及第N+1行像素单元110为例，首先，一扫描芯片（未图示）同时提供两个相同波形的扫描信号Gs(n)、Gs(n+1)给第一扫描线2301及第二扫描线2401，然后再同时提供两个相同波形的扫描信号Gs(n+2)、Gs(n+3) 给第一扫描线2302及第二扫描线2402，依此类推。这些扫描信号Gs(n)、Gs(n+1)、Gs(n+2)及Gs(n+3)需通过所述若干个开关元件260的控制而传输到第N行及第N+1行的第一像素单元1101及第二像素单元1102。具体的说，当第一控制信号20及第二控制信号40为高电压(High)时，对应第一开关信号线270及第二开关信号线280的所述若干个开关元件260导通，使得这些扫描信号Gs(n)、Gs(n+1)、Gs(n+2)及Gs(n+3)可以开启对应的第一像素单元1101及第二像素单元1102的薄膜晶体管的栅极(Gate) ，对应低电压时，对应的开关元件断开。以图3为例，第一扫描线2301、第二扫描线2401、第一扫描线2302及第二扫描线2402实际接收到的扫描信号Gs`(n)、Gs`(n+1)、Gs`(n+2)及Gs`(n+3)如图所示。由此可知，第N行像素单元110是先更新第一像素单元1101的图像信号，然后再更新第二像素单元1102，然后第N+1行像素单元110是先更新第二像素单元1102的图像信号，然后再更新第一像素单元1101。
综上所述，控制单元300可控制每一行像素单元110中第一像素单元1101及第二像素单元1102更新图像信号的顺序。因此，本发明的液晶显示装置通过开关控制扫描线的驱动顺序，进而可各别调整每一行像素单元中，先更新资料线左边的像素单元或者是右边的像素单元。
以下将详细说明一种驱动液晶显示装置的方法，本方法是利用上述较佳实施例的液晶显示装置200来实施。请再参照第2图，该液晶显示装置200包括若干个阵列排列的像素单元110、若干条资料线220、若干条第一扫描线230及若干条第二扫描线240，每一行所述的像素单元110中分为若干个第一像素单元1101及若干个第二像素单元1102，每一所述的资料线220电性连接于每一行所述的一第一像素单元1101及一第二像素单元1102，所述若干个第一像素单元1101及所述若干个第二像素单元1102分别电性连接于所述第一扫描线230及所述第二扫描线240。其中上述元件的说明可参考上述，在此不再予以赘述。
请参照图4，图4是本发明较佳实施例的驱动方法的流程图。所述方法开始于步骤S10。
在步骤S10中，提供若干个开关单元260分别电性连接于所述若干条第一扫描线230及所述若干条第二扫描线240的一端（如图3所示），以控制所述若干条第一扫描线230及所述若干条第二扫描线240的导通状态。
同样的，所述液晶显示装置200还包括一第一开关信号线270及一第二开关信号线280。所述第一开关信号线270通过所述若干个开关元件260电性连接于每一所述的第一扫描线230，其用于同时导通及断开所述若干条第一扫描线230。同样的，所述第二开关信号线280通过所述若干个开关元件260电性连接于每一所述的第二扫描线240，其用于同时导通或断开所述若干条第二扫描线240。
具体而言，所述若干个开关单元260较佳为若干个薄膜晶体管，并且电性连接于所述第一开关信号线270的所述若干个薄膜晶体管是通过若干个栅极端（未图示）电性连接在一起。同样的，电性连接于所述第二开关信号线280的所述若干个薄膜晶体管是通过若干个栅极端（未图示）电性连接在一起。
在步骤S20中，计算所述若干条资料线220先更新所述若干个第一像素单元1101的若干个灰阶值变化的总和，及计算所述若干条资料线220先更新所述若干个第二像素单元1102的若干个灰阶值变化的总和。具体而言，请一并参照图5，图5是图2中数个像素单元的灰阶值示意图。当更新第N+1行的像素单元110之前，假设仅根据虚线框中的像素单元110来判断资料线220a及220b传输所述图像信号的顺序（同理可以扩展到整个面板）。需注意的是，每一像素单元110有各自的图像信号，每一图像信号具有一灰阶值，其值为整数0至255。假设第N行的像素单元110中，资料线220a及220b最后更新的像素单元110为灰阶值为a1及b1的第二像素单元1102。
其中计算所述若干条资料线220先更新第一像素单元1101的若干个灰阶值变化的总和，即为计算资料线220a及220b先更新第N+1行像素单元110的灰阶值为a2及b2的第一像素单元1101的灰阶值变化。而灰阶值变化的总和△Q1以数学式表示为△Q1=|a1-a2|+|b1-b2|。同样的，其中计算所述若干条资料线220先更新第二像素单元1102的若干个灰阶值变化的总和，即为计算先更新第N+1行像素单元110的灰阶值为a3及b3的第二像素单元1102的灰阶值变化。而灰阶值变化的总和△Q2以数学式表示为△Q2=|a1-a3|+|b1-b3|。
在步骤S30中，根据两者总和△Q1及△Q2的大小，选择每行像素单元110的所述若干个第一像素单元1101及所述若干个第二像素单元1102更新的顺序并进行更新，该顺序可以为先更新若干个第一像素单元1101与若干个第二像素单元1102中的灰阶值变化总和的较小者。
举例而言，所述控制单元300是用于执行步骤S20及步骤S30，控制单元300电性连接于第一开关信号线270及第二开关信号线280的一端，用以输出一第一控制信号20到第一开关信号线270，以及输出一第二控制信号40到第二开关信号线280。通过第一控制信号20及第二控制信号40控制对应的所述若干个开关元件260的导通顺序，进而控制在每一行的像素单元110中，是先更新第一像素单元1101或是先更新第二像素单元1102。
当先更新第一像素单元1101的所述若干个灰阶值变化的总和△Q1大于先更新第二像素单元1102的所述若干个灰阶值变化的总和△Q2时，所述若干个开关单元260（对应第二开关信号线280）导通，继而所述第二扫描线240被施加高电压信号以先更新第二像素单元1102，而后导通第一扫描线230以更新第一像素单元1101。简言之，当△Q1 > △Q2，则控制第一控制信号20及第二控制信号40，使得第二扫描线2402先传，第一扫描线2302后传。
同样的，当先更新第二像素单元1102的所述若干个灰阶值变化的总和△Q2大于先更新第一像素单元1101的所述若干个灰阶值变化的总和△Q1时，所述若干个开关单元260（对应第一开关信号线270）导通，继而所述第一扫描线230被施加高电压信号以先更新第一像素单元1101，而后导通第二扫描线240以更新第二像素单元1102。简言之，当△Q1 < △Q2，则控制第一控制信号20及第二控制信号40，使得第一扫描线2302先传，第二扫描线2402后传。
综上所述，本发明的驱动液晶显示装置的方法可根据不同的画面（即图像信号）分析资料线跳变的灰阶变化较小的驱动路径而改变扫描线更新的顺序。由此可知，由灰阶变化较小的路径可以理解资料线跳变的电压差值也较少，因而可以降低数据芯片功率的消耗。
虽然本发明已用较佳实施例揭露如上，然其并非用以限定本发明，本发明所属技术领域中具有通常知识者，在不脱离本发明的精神和范围内，当可作各种的更动与润饰，因此本发明的保护范围当视后附的申请专利范围所界定者为准。
