实施例8：
如图4-5所示，通过调节将W子像素所对应的子像素电极处的沟道区的宽度D设置为大于RGB子像素所对应的子像素电极处的沟道区的宽度D，使载流子会更慢的通过沟道区，具有更低的充电效率，因此降低了W子像素的亮度，即W子像素的亮度相对于常规的W子像素的亮度更低；本实施例适用于第二使用场景。
实施例9：

实施例12：
如图5-3所示，通过减小W子像素的面积，即使W子像素的面积小于RGB子像素的面积，从而实现对W子像素处的开口率进行调整，具体地，将W子像素101区域的黑色矩阵300的线宽设置为小于RGB子像素(101、102、103)区域的黑色矩阵300的线宽实现，使W子像素开口率减小，光效率降低，W子像素具有更低的透过率，降低了W子像素的亮度，即W子像素的亮度相对于常规的W子像素的亮度更低；本实施例适用于第二使用场景。
本还可采用将实施例1-12中的两种或以上进行结合，从而进一步地满足W子像素亮度的要求，在此不做具体赘述。
在上述实施例1-12中，液晶显示器为FFS(Fringe Field Switching,边缘场开关技术)模式液晶显示器，在其他模式的液晶显示器中也可以通过实施例1-12的方式来实现W子像素相比常规设计中W子像素更亮或更暗的设计。例如还可以在VA(Vertical Alignment，垂直配向型)模式的液晶显示器中W子像素所对应的子像素电极具有更小面积。本提案对液晶显示器的显示模式不做 限定。
