Description

三色和四色像素显示面板驱动系统和方法 技术领域
本申请涉及一种显示面板,特别是涉及一种在显示面板设计维持不变更的前提下,仅改变面板的驱动电路配置即可实现的三色和四色像素显示面板驱动系统和方法。
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,大多数是以红色子像素(R)、绿色子像素(G)和蓝色子像素(B)组成一个像素单元。通过控制红色子像素的R数据、绿色子像素的G数据以及蓝色子像素的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,出现了具有由红色子像素(R)、绿色子像素(G)和蓝色子像素(B)和白色子像素(W)组成的一个四像素单元的显示面板,从而改善了基于三像素的显示面板的显示质量。
然而,随着人们节能减排的意识逐步增强,RGBW技术的节能优势日益突出和显现,在RGBW技术给消费者带来白画面下高亮度,高对比度,背光节能30%~50%等等好的体验的同时,也给LCD面板制造商带来巨大的资金投入。现有的四色像素显示面板相比于RGB面板还需引进白色像素点,所以相应的制造设备也要做相应的改动,光罩也和RGB面板不能共享,材料开发投入,人力投入以及产能投入等。

三色像素显示面板与四色像素显示面板之间的差异仅在于四色像素显示面板还包括白色子画素W,因此本领域技术人员应理解的是,除此差异之外的上述四色像素显示面板的结构和驱动方式等可以选择性地应用至三色像素显示面板,反之亦然。
需要说明的是,在所述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详细描述的部分,可以参见其他实施例的相关描述。
