Description

一种显示面板的驱动数据的转换方法及转换系统 技术领域
本发明属于显示技术领域，具体地讲，涉及一种显示面板的驱动数据的转换方法及转换系统。
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)组成一个像素单元的显示面板，从而改善了基于三子像素的显示面板的显示质量。
在现有技术的基于四子像素的显示面板中，将输入的RGB数据的最小值作为输出的W值。在这种情况下，白色子像素单元的加入使得基于四子像素的显示面板的亮度得到了极大的提升，同时也降低了显示装置的功耗。但是，由于亮度的提升，使得基于四子像素的显示面板相较于基于三子像素的显示面板，其显示的色域范围变小，色彩饱和度降低。

如果所述饱和度值小于所述预定饱和度值，则第二赋值单元47令M＝M+1。
判断单元48判断M是否小于10。
如果M不小于10，则输出单元46将所述中间的RGBW数据作为所述输出的RGBW数据。
如果M小于0，则第一附值单元42进一步被构造为令A(m,n)＝1-q×M，其中，q大于0且小于1。
图4是根据本发明的实施例的显示面板的驱动数据的转换方法的流程图。
参照图4，在操作410中，用于将输入的RGB数据转换为输出的RGBW 数据的显示面板的驱动数据的转换系统初始化M＝0。
在操作420中，令A(m,n)＝1-q×M，其中，q大于0且小于1，(m,n)表示所述显示区的位置坐标，A(m,n)表示所述显示区对应的调整参数。
在操作430中，根据所述调整参数将输入的RGB数据转换为所述显示区对应的中间的RGBW数据。进一步地，根据所述调整参数利用上面的式子1将输入的RGB数据转换为中间的RGBW数据。
在操作440中，根据所述中间的RGBW数据计算出HSV颜色空间的饱和度值。进一步地，根据所述中间的RGBW数据利用上述的式子2计算出HSV颜色空间的饱和度值。
在操作450中，判断所述饱和度值是否不小于所述显示区对应的预定饱和度值。
如果所述饱和度值不小于所述预定饱和度值，则执行操作460。在操作460中，将所述中间的RGBW数据作为所述输出的RGBW数据。
如果所述饱和度值小于所述预定饱和度值，则执行操作470。在操作470中，令M＝M+1。
在操作480中，判断M是否小于10。如果M小于10，则返回操作420中。
如果M不小于10，则执行操作460。
综上所述，根据本发明的实施例的显示面板的驱动数据的转换系统及转换方法，能够提高显示装置显示的画面的色彩饱和度，从而提高显示装置的显示质量。
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。
