Description

液晶显示器的驱动方法以及液晶显示器
【技术领域】
本发明涉及液晶显示领域，特别是涉及一种液晶显示器的驱动方法以及液晶显示器。
【背景技术】
伴随着科技的发展，不同类型的具有液晶显示器的智能设备以及电子产品成为人们生活不可或缺的一部分，但是不管是大尺寸还是小尺寸的液晶显示器，都需要背光光源，现有的液晶显示器的背光光源一般都采用面光源背光模组。
面光源为一种平面发光源，按照形态分，主要包括小型荧光灯、冷光片、发光二极管，其中，因发光二极管具有低工作电压、低功耗和使用寿命长等优点广泛地用作为液晶显示设备的背光模组的背光源。
以LED背光源为例来说明，背光模组主要包括扩散片、棱镜片、导光板、反射层和LED 背光源，其中，反射层位于导光板的下方，棱镜片位于导光板的上方，扩散片位于棱镜片的上方，LED 背光源设置于导光板的一侧。LED 产生的光，经导光板的侧面射入，再经导光板表面的均光处理以及反射层的光反射，最后透过棱镜片和扩散片产生平面光源。
然而由于LED背光源一般都采用多个LED间隔设置在印刷电路板上，当LED 数量较少且位于导光板的一侧时，由于LED 光源的发散角受到限制，在导光板靠近LED 光源的区域出现暗区，而在其他一些地方，又出现相邻LED光的叠加，出现亮区，降低了导光板出光的均匀性，且由于发光二极管产生的光线为立体广角而并非平行角度，致使射入导光板的光线也不均匀，最终导致液晶显示器的显示画面的显示效果不均匀。
【发明内容】

【具体实施方式】
参阅图1，图1是本发明液晶显示器的驱动方法一实施方式的流程示意图。如图1所示，本实施方式的驱动方法包括如下步骤：
101：获取液晶显示器的至少两个显示区域分别对应的Gamma值，其中所述至少两个显示区域分别对应的Gamma值不相同，且所述至少两个显示区域的背光情况不同。
其中，该液晶显示器包括智能手机、平板电脑、PC机，液晶电视等液晶显示设备中的至少一种。
由于每个像素所处区域的背光情况不同，对应到液晶显示器时，如果采用相同的驱动电压，液晶显示器会出现明暗不均匀的画面，为了克服上述问题，即为了保证液晶显示器显示的画面整体亮度均匀，液晶显示装置首先根据其背光情况将其像素区域划分成至少两个不同显示区域，例如三个、四个或者更多个显示区域，在此不做限定。
每个不同的显示区域对应不同的Gamma值，其中，液晶显示装置将该不同的Gamma值存储在寄存器中，如液晶显示器的驱动IC的存储器中。
其中，不同显示区域对应的的Gamma值可以存储在相同的寄存器中，也可以存储在不同的寄存器中。
在一个具体的实施中，液晶显示器将根据背光情况将液晶像素区域划分成三个显示区域，第一显示区域、第二显示区域以及第三显示区域，其中第一显示区域、第二显示区域以及第三显示区域的背光亮度以此递减，如图2所示，图2为本发明显示区域划分一实施方式的结构示意图。当该液晶显示器的背光光源选择为LED光源时，根据LED光源的LED灯所提供的背光的亮度的不同，将该液晶显示器的显示区域划分为亮度依次递减的S1区域、S2区域以及S3区域。其中，S1区域对应第一显示区域，S2区域对应第二显示区域，S3区域对应第三显示区域。
其中，第一显示区域对应第一第一Gamma值，第二显示区域对应的第二Gamma值，第三显示区域对应的第三Gamma值，因为Gamma值越大，与该Gamma值一一对应的Gamma曲线越靠近灰阶值X轴，即显示的整体亮度就越低，因此，第一Gamma值、第二Gamma值、第三Gamma值依序减小。在一般的实施方式中，为了使整体显示亮度正常、均匀化，位于中间大小的第二Gamma值一般选择为标准值，如2.2另外的第一Gamma值和第三Gamma值分别设定为大于标注值的数值和小于标准值的数值。在本实施方式中，第一Gamma值为3，第二Gamma值为2.2，第三Gamma值为1，具体的三个Gamma值对应的Gamma曲线对照图如图3所示。如图3所示，横轴表示显示图像的灰阶值，纵轴表示显示图像的亮度，靠近横轴从下到上的三条曲线Gamma曲线分别对应第一Gamma值、第二Gamma值以及第三Gamma值。
需要说明的是，上述三个Gamma值只是举例说明，而非对划分为三个不同显示区域时Gamma值的限定，在其他实施方式中，也可以根据实际情况设定其他的Gamma值，在此不做限定。
液晶显示器在显示图像时，首先从其寄存器中获取其预先划分的至少两个显示区域分别对应的Gamma值。
102：根据所述至少两个显示区域分别对应的Gamma值以及待显示图像在所述至少两个显示区域的灰阶值，确定所述至少两个显示区域中像素的驱动电压。
液晶显示器在确定至少两个显示区域分别对应的Gamma值后，由于Gamma值与Gamma曲线为一一对应的关系，只要确定Gamma曲线横轴对应的待显示图像在所述至少两个显示区域的灰阶值，就能够确定待显示图像在所述至少两个显示区域的显示亮度值。又由于该显示亮度值是通过该至少两个显示区域中像素的驱动电压来确定，因此，液晶显示器在确定该至少两个显示区域分别对应的Gamma值后，根据待显示图像在所述至少两个显示区域的灰阶值，即可确定所述至少两个显示区域中像素的驱动电压。
在另一个实施方式中，如图4所示，本实施方式的液晶显示器的驱动方法在确定所述至少两个显示区域中像素的驱动电压的步骤之后，还包括步骤403：通过所述驱动电压驱动所述至少两个显示区域中像素点亮。
通过不同大小的驱动电压驱动至少两个显示区域中像素点亮，驱动电压产生的亮度差能够很好的平衡掉由于背光情况不同而产生的亮度差，使液晶显示器整个画面的亮度均匀化。
例如，再次结合图2以及图3，第一显示区域的亮度大于第三显示区域的亮度，而由于第一显示区域对应的Gamma值大于第三显示区域对应的Gamma值，即在相同的灰阶值，第一显示区域对应的显示亮度低于第三显示区域的亮度，通过Gamma值不同带来的亮度差平衡了由于背光情况不同带来的亮度差值，使液晶显示器整个画面的亮度均匀化。
区别于现有技术，本实施方式的液晶显示器在显示图像时，获取的至少两个背光情况不同的显示区域分别对应的不同的Gamma值，并根据该不同的Gamma值以及待显示图像在所述至少两个显示区域的灰阶值，确定所述至少两个显示区域中像素的驱动电压。通过上述不同背光选择不同Gamma值的驱动方式，能够有效平衡掉由于背光情况不同而导致的显示画面亮暗不均匀的情况，且，无需改变液晶显示器的内部结构，操作方便。
参阅图5，图5是本发明液晶显示器一实施方式的结构示意图。如图5所示，本实施方式的液晶显示器包括智能手机、平板电脑、PC机，液晶电视等液晶显示设备中的至少一种。具体包括Gamma值获取模块501以及驱动电压确定模块502。
Gamma值获取模块501用于获取液晶显示器的至少两个显示区域分别对应的Gamma值，其中所述至少两个显示区域分别对应的Gamma值不相同，且所述至少两个显示区域的背光情况不同。
电压确定模块502用于根据所述至少两个显示区域分别对应的Gamma值以及待显示图像在所述至少两个显示区域的灰阶值，确定所述至少两个显示区域中像素的驱动电压。
具体地，为了清楚说明液晶显示器的工作过程，进一步参与图6，图6是本发明液晶显示器另一实施方式的结构示意图，为了保证液晶显示器显示的画面整体亮度均匀，该液晶显示器还包括显示区域划分模块603，区域划分模块603根据其背光情况将其像素区域划分成至少两个不同显示区域，例如三个、四个或者更多个显示区域，在此不做限定。
每个不同的显示区域对应不同的Gamma值，其中，液晶显示装置将该不同的Gamma值存储在寄存器中，如液晶显示器的驱动IC的存储器中。
其中，不同显示区域对应的的Gamma值可以存储在相同的寄存器中，也可以存储在不同的寄存器中。
在一个具体的实施中，区域划分模块603将根据背光情况将液晶像素区域划分成三个显示区域，第一显示区域、第二显示区域以及第三显示区域，其中第一显示区域、第二显示区域以及第三显示区域的背光亮度以此递减。
其中，第一显示区域对应第一第一Gamma值，第二显示区域对应的第二Gamma值，第三显示区域对应的第三Gamma值，因为Gamma值越大，与该Gamma值一一对应的Gamma曲线越靠近灰阶值X轴，即显示的整体亮度就越低，因此，第一Gamma值、第二Gamma值、第三Gamma值依序减小。在一般的实施方式中，为了使整体显示亮度正常、均匀化，位于中间大小的第二Gamma值一般选择为标准值，如2.2另外的第一Gamma值和第三Gamma值分别设定为大于标注值的数值和小于标准值的数值。在本实施方式中，第一Gamma值为3，第二Gamma值为2.2，第三Gamma值为1。
需要说明的是，上述三个Gamma值只是举例说明，而非对划分为三个不同显示区域时Gamma值的限定，在其他实施方式中，也可以根据实际情况设定其他的Gamma值，在此不做限定。
Gamma值获取模块601在液晶显示器在显示图像时，首先从其寄存器中获取其预先划分的至少两个显示区域分别对应的Gamma值。
由于Gamma值与Gamma曲线为一一对应的关系，只要确定Gamma曲线横轴对应的待显示图像在所述至少两个显示区域的灰阶值，就能够确定待显示图像在所述至少两个显示区域的显示亮度值。又由于该显示亮度值是通过该至少两个显示区域中像素的驱动电压来确定，因此，驱动电压确定模块602在Gamma值获取模块601确定该至少两个显示区域分别对应的Gamma值后，根据待显示图像在所述至少两个显示区域的灰阶值，即可确定所述至少两个显示区域中像素的驱动电压。
进一步的参阅图7，液晶显示装置还包括显示模块704，显示模块704用于通过所述驱动电压驱动所述至少两个显示区域中像素点亮。
通过不同大小的驱动电压驱动至少两个显示区域中像素点亮，驱动电压产生的亮度差能够很好的平衡掉由于背光情况不同而产生的亮度差，使液晶显示器整个画面的亮度均匀化。
例如，第一显示区域的亮度大于第三显示区域的亮度，而由于第一显示区域对应的Gamma值大于第三显示区域对应的Gamma值，即在相同的灰阶值，第一显示区域对应的显示亮度低于第三显示区域的亮度，通过Gamma值不同带来的亮度差平衡了由于背光情况不同带来的亮度差值，使液晶显示器整个画面的亮度均匀化。
区别于现有技术，本实施方式的Gamma值获取模块在液晶显示器在显示图像时，获取的至少两个背光情况不同的显示区域分别对应的不同的Gamma值，驱动电压确定模块根据该不同的Gamma值以及待显示图像在所述至少两个显示区域的灰阶值，确定所述至少两个显示区域中像素的驱动电压。通过上述不同背光选择不同Gamma值的驱动方式，能够有效平衡掉由于背光情况不同而导致的显示画面亮暗不均匀的情况，且，无需改变液晶显示器的内部结构，操作方便。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
