Description

液晶显示器及成像控制的方法
技术领域
本发明涉及显示器技术领域 ，具体涉及一种液晶显示器及成像控制的方法。
　　　背景技术
随着液晶技术的发展，市场对液晶显示器的解析度、能耗等级等性能要求越来越高。为了降低功耗，现有技术中，在通常的2D显示模式下，通过将W（白色）整合进像素的三原色R（红色）、G（绿色）、B（蓝色）之中，来增加液晶显示器整体穿透率，由于W（白色）子像素没有彩色滤光层，减少了W（白色）色子像素的滤光层对光的吸收，所以背板发光组件可以较低的发光强度来满足显示器的成像需求，从而降低了液晶显示器的功耗。
然而，目前大部分显示器均需要附带3D显示功能，显示器一般运用FPR（Film-type Patterned Retarder，图形化相位延迟膜）技术实现3D效果，在实现3D效果的过程中需要比较宽的挡光区域来防止左右眼串扰，现有技术一般采用牺牲像素显示区域作为黑色挡光区域来防止左右眼串扰，但是，这样就使得显示器的透光区域降低，从而背板发光组件需要以较大功率工作来发射亮度较大的光线，以满足显示器的成像需求，增大了液晶显示器的功耗，也提高了生产成本，降低了产品竞争力。
　　　上述内容仅用于辅助理解本发明的技术方案，并不代表承认上述内容是现有技术。
　　　发明内容
本发明的主要目的在于提供一种液晶显示器及防图像串扰的控制方法，旨在解决RGBW显示模式下3D液晶显示器功耗大、生产成本高的问题。
为实现上述目的，本发明提供一种液晶显示器，包括显示单元，所述显示单元包括第一显示模式和第二显示模式，所述显示单元的各个像素由红色、绿色、蓝色和白色子像素组成，其中：
在第一显示模式下，所述显示单元驱动红色、绿色、蓝色和白色子像素；
在第二显示模式下，所述显示单元驱动红色、绿色和蓝色，停止驱动白色子像素。
优选地，所述第一显示模式为2D显示模式，所述第二显示模式为3D显示模式。
优选地，所述红色、绿色和蓝色子像素相互平行设置，所述白色子像素与所述红色、绿色和蓝色子像素垂直且不相交。
优选地，所述红色、绿色、蓝色和白色子像素相互平行设置。
优选地，所述白色子像素竖直或者水平设置。
本发明同时提出一种上述液晶显示器进行成像控制的方法，包括如下步骤：
当所述液晶显示器处于第一显示模式下，控制所述显示单元驱动红色、绿色、蓝色和白色子像素发光；
当所述液晶显示器处于第二显示模式下，控制所述显示单元驱动红色、绿色和蓝色子像素发光，停止驱动白色子像素。
本发明通过设置显示单元，所述显示单元包括第一显示模式和第二显示模式，所述显示单元的各个像素由红色、绿色、蓝色和白色子像素组成，所述液晶显示器在第一显示模式（例如，2D显示模式）时，控制所述显示单元驱动红色、绿色、蓝色和白色子像素发光，提高了显示单元的透光率，减小了对液晶显示器背板发光强度的要求，从而降低了液晶显示器的功耗；所述液晶显示器在第二显示模式（例如，3D显示模式）下，控制所述显示单元驱动红色、绿色和蓝色子像素发光，停止驱动白色子像素使其不发光，从而白色子像素形成黑态不透光区域，并作为液晶显示器运用FPR技术实现3D效果时的挡光区域，防止左右眼图像串扰，这样就不需要停止驱动红色、绿色和蓝色像素显示区域作为黑色挡光区域，避免使液晶显示器的透光区域过大而导致显示单元的透光率过低，从而减小了对液晶显示器背板发光强度的要求，降低了液晶显示器的功耗；这样，液晶显示器无论是在第一显示模式（例如，2D显示模式）下或者第二显示模式（例如，3D显示模式）下，其功耗更低、更具有市场竞争力。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
　　　具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
　　　本发明提供一种液晶显示器，包括显示单元，所述显示单元包括第一显示模式和第二显示模式，所述显示单元的各个像素由红色、绿色、蓝色和白色子像素组成，其中：在第一显示模式下，所述显示单元驱动红色、绿色、蓝色和白色子像素；在第二显示模式下，所述显示单元驱动红色、绿色和蓝色，停止驱动白色子像素。
在本实施例中，本发明包括显示单元，所述显示单元包括第一显示模式和第二显示模式，所述显示单元的各个像素由红色、绿色、蓝色和白色子像素组成，所述液晶显示器在第一显示模式（例如，2D显示模式）时，控制所述显示单元驱动红色、绿色、蓝色和白色子像素发光，提高了显示单元的透光率，减小了对液晶显示器背板发光强度的要求，从而降低了液晶显示器的功耗；所述液晶显示器在第二显示模式（例如，3D显示模式）下，控制所述显示单元驱动红色、绿色和蓝色子像素发光，停止驱动白色子像素使其不发光，从而白色子像素形成黑态不透光区域，并作为液晶显示器运用FPR技术实现3D效果时的挡光区域，防止左右眼图像串扰，这样就不需要停止驱动红色、绿色和蓝色像素显示区域作为黑色挡光区域，避免使液晶显示器的透光区域过大而导致显示单元的透光率过低，从而减小了对液晶显示器背板发光强度的要求，降低了液晶显示器的功耗；这样，液晶显示器无论是在第一显示模式（例如，2D显示模式）下或者第二显示模式（例如，3D显示模式）下，其功耗更低、更具有市场竞争力。
进一步地，参见图1和图3，所述红色、绿色和蓝色子像素相互平行设置，所述白色子像素与所述红色、绿色和蓝色子像素垂直且不相交，所述白色子像素竖直或者水平设置。在本实施例中，W为白色子像素，R为红色子像素，G为绿色子像素，B为蓝色子像素。图1和图3的左侧所示为液晶显示第一显示模式（例如，2D显示模式）的像素显示状态，所述显示单元驱动红色、绿色、蓝色和白色子像素发光。图1和图3的右侧为第二显示模式（3D显示模式）的像素显示状态，所述显示单元驱动红色、绿色和蓝色子像素发光，停止驱动白色子像素发光呈黑色，白色子像素为黑态充当阻挡左右眼显示串扰的挡光区域，这样就不需额外增加挡光区域，从而避免造成发光单元透光率下降，即降低了对所述液晶显示器背板发光强度的要求和液晶显示器的功耗。
同样的，参见图2和图4，所述红色、绿色、蓝色和白色子像素相互平行设置，所述白色子像素竖直或者水平设置。
本发明还提供一种对上述的液晶显示器进行成像控制的方法，包括如下步骤：
当所述液晶显示器处于第一显示模式下，控制所述显示单元驱动红色、绿色、蓝色和白色子像素发光；
当所述液晶显示器处于第二显示模式下，控制所述显示单元驱动红色、绿色和蓝色子像素发光，停止驱动白色子像素。
　　　应当理解，以上仅为本发明的优选实施例，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。
