Description

显示器和其驱动方法 技术领域
本发明是有关于一种显示器，尤指一种可减少源极驱动器信道数量的显示器和其驱动方法。
 背景技术
现有的显示面板（LCD panel）的显示设备中，均是以红色（R）子像素、绿色（G）子像素和蓝色（B）子像素组成一个像素单元，通过控制每个子像素的的灰阶值，混合出所需要显示的色彩以显示彩色图像。随着信息技术的发展，对于显示面板的各种需求也在增加，高透过率、低功耗、较佳的成像质量也成为人们对显示面板的需求。现有RGB三原色显示面板的穿透率以及混合效率都比较低，因此导致显示面板的功耗大。
因此现有技术另外提供由红色（R）子像素、绿色（G）子像素、蓝色（B）子像素和白色（W）子像素组成一个像素单元。相较于RGB显示器，由RGBW四个子像素做为像素单元的显示器，其像素的分辨率较大、穿透率较高且色彩变化较多，因此有较佳的显示质量。
对于分辨率为1080×1920的RGB显示器来说，每一行具有3240(1080×3)个子像素，因此源极驱动器需要3240个信道来传输数据信号至3240个子像素。虽然RGBW显示器可以利用子像素共享技术可以将源极驱动器需要的信道数量减少至2160个，但是若能进一步减少源极驱动器的信道数量，将使显示器的设计布局更具弹性。
因此如何制造一种减少源极驱动器的信道数量的显示器是业界努力的目标。

 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之特定实施例。本发明所提到的方向用语，例如“上”、“下”、“前”、“后”、“左”、“右”、“顶”、“底”、“水平”、“垂直”等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参阅图1，图1是本发明显示器100一较佳实施方式的示意图。显示器100可为液晶显示器或是有机发光二极管显示器，可做为个人计算机的屏幕或是笔记本电脑的屏幕。显示器100包含时序控制器104、源极驱动器106、栅极驱动器108以及显示面板110。显示面板110包含多条扫描线G1-Gk、多条数据线D1-D4m和多个像素单元130。多个像素单元130呈矩阵排列，每一像素单元130至少包括红、绿、蓝、白四个子像素单元120。所述子像素单元120设置于多条扫描线G1-Gk与多条数据线D1-D4m交错的区域之间。时序控制器104产生的垂直同步信号传送至栅极驱动器108时，栅极驱动器108会依序产生扫描脉冲经由扫描线G1-Gk传送至显示面板110，在此同时，时序控制器104则会发出水平同步信号至源极驱动器106，而源极驱动器106就会经由数据线D1-D4m并行输出灰阶电压信号至显示面板110的子像素单元120。每一子像素单元120包含像素电极124和薄膜晶体管122，薄膜晶体管122的栅极、源极和漏极分别电性连接相应子像素单元120中的扫描线、数据线和像素电极124。栅极驱动器108用来通过扫描线G1-Gk传输扫描脉冲，源极驱动器106用来通过数据线D1-D4m传输数据电压信号。
请参阅图2，图2是本发明显示面板110的示意图。每一像素单元130由沿着行方向排列的红色子像素120R、绿色子像素120G、蓝色子像素120B和白色子像素120W组成。为了便于说明本实施例，在此将同一行上的相邻两像素单元130分为第一像素单元130a和第二像素单元130b。第一像素单元130a与第二像素单元130b是交替排列。当第一像素单元130a接收第一帧影像时，源极驱动器106通过数据线提供显示第一极性的数据信号至像素单元130a。当第二像素单元130b接收第一帧影像时，源极驱动器106通过数据线提供显示第二极性的数据信号至像素单元130b。当第一像素单元130a接收第二帧(亦即第一帧的下一帧)影像时，源极驱动器106通过数据线提供显示第二极性的数据信号至像素单元130a。当第二像素单元130b接收第二帧影像时，源极驱动器106通过数据线提供显示第一极性的数据信号至像素单元130b。该第一极性相反于该第二极性。具体来说，第一极性是正极性时，第二极性是负极性。当源极驱动器106提供正极性的数据信号至像素单元130时，数据信号与公共电极的电压的差值是正值；当源极驱动器106提供负极性的数据信号至像素单元130时，数据信号与公共电极的电压的差值是负值。第一像素单元130a与第二像素单元130b随着每一帧画面的切换交替轮流根据第一极性和第二极性的数据信号显示影像。
请参阅图3，图3是本发明源极驱动器、各个开关单元和像素单元的示意图。第一开关单元SW1电性连接源极驱动器106及第一像素单元130a的红色子像素120R1。第二开关单元SW2电性连接源极驱动器106及第二像素单元130b的绿色子像素120G2。第三开关单元SW3电性连接源极驱动器106及第二像素单元130b的蓝色子像素120B2。第四开关单元SW4电性连接源极驱动器106及第一像素单元130a的白色子像素120W1。第五开关单元SW5电性连接源极驱动器102及第二像素单元130b的红色子像素120R2。第六开关单元SW6电性连接源极驱动器106及第一像素单元130a的绿色子像素102G1。第七开关单元SW7电性连接源极驱动器106及第一像素单元130a的蓝色子像素120B1。第八开关单元SW8电性连接源极驱动器106及第二像素单元130b的白色子像素120W2。
请参阅图3、图4和图5。图4是本发明驱动显示器的方法流程图，图5是本发明驱动时各开启信号和扫描信号的时序图。本发明的驱动显示器的方法包含：
步骤402：当接收第一开启信号MUXR时，第一开关单元SW1导通由源极驱动器106的第一信道CH1送出的第一极性的数据信号R(2n)至第一像素单元130a的红色子像素120R1，第五开关单元SW5导通由源极驱动器106的第二信道CH2送出的第二极性的数据信号R(2n+1)至第二像素单元130b的红色子像素120R2。
步骤404：当接收第二开启信号MUXG时，第二开关单元SW2导通由第一信道CH1送出的第一极性的数据信号G(2n+1)至第二像素单元130b的绿色子像素120G2，第六开关单元SW6导通第二信道CH2送出的第二极性的数据信号G(2n)至第一像素单元130a的绿色子像素120G1。
步骤406：当接收第三开启信号MUXB时，第三开关单元SW3导通由第一信道CH1送出的第一极性的数据信号B(2n+1)至第二像素单元130b的蓝色子像素120B2，第七开关单元SW7导通由第二信道CH2送出的第二极性的数据信号B(2n)至第一像素单元130a的蓝色子像素120B1。
步骤408：当接收第四开启信号MUXW时，第四开关单元SW4导通由第一信道CH1送出的第一极性的数据信号W(2n)至第一像素单元130a的白色子像素120W1，第八开关单元SW8导通由第二信道CH2送出的第二极性的数据信号W(2n+1)至第二像素单元130b的白色子像素120W2。
请注意，在本实施例中，第一像素单元130a的红色和白色子像素120R1、120W1的数据信号是由第一信道CH2所传输，第二像素单元130b的红色和白色子像素120R2、120W2的数据信号是由第二信道CH2所传输。第一像素单元130a的绿色和蓝色子像素120G1、120B1的数据信号是由第二信道CH2所传输，第二像素单元130b的绿色和蓝色子像素120G2、120B2的数据信号是由第一信道CH1所传输。
由于源极驱动器106的每一信道连接到一个1:4复用器(multiplexer)，因此每一像素单元(包含四个RGBW子像素单元)只连接到源极驱动器106的一个信道。因此可以大幅度地减少源极驱动器所需的信道数量。
本发明的显示器以及其驱动方法使用的源极驱动器的信道只有RGB显示器的一半，因此可以减少源极驱动器的信道数量，也能减小源极驱动器芯片内输出端的缓冲运算放大器(buffer operation amplifier)数量，从而降低源极驱动器芯片的功耗和体积大小，达到降低源极驱动器芯片功耗和成本的有益效果。
综上所述，虽然本发明已以较佳实施例揭露如上，但该较佳实施例并非用以限制本发明，该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。
