Description
技术领域
本发明属于显示技术领域,具体地讲,涉及一种三色数据到四色数据的转换系统及转换方法。
背景技术
目前,在具有例如液晶显示面板或有机发光二极管(OLED)显示面板的显示装置中,大多数是以红色(R)子像素单元、绿色(G)子像素单元和蓝色(B)子像素单元组成一个像素单元。通过控制红色子像素单元的R数据、绿色子像素单元的G数据以及蓝色子像素单元的B数据,混合出显示面板所需要显示的色彩来显示彩色图像。
随着信息技术的发展,对于显示面板的各种需求也在增加,高穿透率、低功耗、成像质量佳成为人们对显示面板的需求。现有的RGB三原色混光显示方式的穿透率以及混合效率都比较低,导致显示面板的功耗大,制约了显示面板的优化。基于此,出现了具有由红色(R)子像素单元、绿色(G)子像素单元、蓝色(B)子像素单元和第四子像素单元(例如白色(W)子像素单元)组成的一个四像素单元的显示面板,由于W子像素单元的穿透率非常高,可以极大的提高显示面板的穿透率,从而可以相对降低背光的亮度,以实现节能的效果。
通常,图像或视频是由RGB三通道存储信息的,但是四像素单元的显示面板需要利用WRGB四个子像素单元进行显示,这就需要将输入的RGB数据转换成WRGB数据输出。然而,现有的三色(即,RGB)数据到四色(即,WRGB)数据的转换方法无法针对不同的输入的RGB值获得最佳的输出的W值,即无法最大程度的提高显示面板的穿透率。

在步骤430中,将亮度提升的RGB值中的最小值Min(R1,G1,B1)作为输出的W值。这里,如果输出的W值大于255,则白色确定部件43将其输出的W值保持为255。
在步骤440中,基于亮度提升的RGB值及输出的W值计算出输出的RGB值。进一步地,在步骤440中,可利用上面的式子4计算出输出的RGB值。
综上所述,根据本发明的实施例的三色数据到四色数据的转换系统及转换方法,能够针对不同的输入的RGB值获得最佳的输出的W值,最大程度的提高显示装置的穿透率,使得显示装置在提升穿透率的同时提高显示画面的饱和度。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
