Definitions

  • the present invention belongs to the field of display technologies, and in particular, to a conversion system and a conversion method for three-color data to four-color data.
  • OLED display technology is a self-luminous display technology using an organic thin film as an illuminant. Its working principle is: under the driving of external voltage, the electrons and holes injected by the electrode are organic. The composite material emits energy and transmits the energy to the molecules of the organic luminescent material. The molecules of the organic luminescent material are excited to transition from the ground state to the excited state. When the excited molecule returns from the excited state to the ground state, the radiation transition produces a luminescence phenomenon.
  • Different luminescent materials correspond to different colors of light.

Description

一种三色数据到四色数据的转换方法及转换*** 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***及转换方法。
背景技术
有机发光二极管(Organic Light-Emitting Diode，OLED)显示技术是一种以有机薄膜作为发光体的自发光显示技术，其工作原理是：在外界电压驱动下，由电极注入的电子和空穴在有机材料中复合放出能量，并将能量传递给有机发光物质的分子，有机发光物质的分子受到激发，从基态跃迁到激发态，当受激分子从激发态回到基态时辐射跃迁产生了发光现象。
不同的发光物质对应着不同颜色的光，通常使用的OLED有三种：第一种是只发白光的OLED，其只具有一种有机物，且其在OLED显示器中发出的白光需经过彩色滤光片(Color Filter)来形成红绿蓝(RGB)三色)；第二种是分别发出RGB三种颜色光的彩色OLED，其具有三种有机物，并且其发出的RGB三色光合成白色光；第三种是分别发出RGBW四种颜色光的OLED，其具有四种有机物，其中，白色光可由单独的W子像素产生。其中，RGBW-OLED显示器除了具有普通OLED的轻薄、广视角、高对比度等优点外，还包括了W子像素，使得其不仅可以在不使用彩色滤光片的条件下便可实现所有颜色的显示，而且单独的W子像素也会对显示亮度有很大的提高，节省功耗。
然而，RGBW-OLED显示器虽然具有以上的优点，但是其各个子像素的寿命不同，例如，蓝色子像素寿命＜红色子像素寿命＜绿色子像素寿命。RGBW-OLED显示器的寿命由寿命最短的蓝色子像素决定，随着使用时间的增加，蓝色子像素老化得最快，其亮度逐渐降低，从而使RGBW-OLED显示器显示的画面出现色偏。另外，白色(W)子像素的引入也会导致RGBW-OLED显示器显示的画面的色彩饱和度下降，影响画面显示的效果。

这里，需要说明的是，如果饱和度对比单元42判断该实际饱和度值不小于该预定饱和度值，则第一饱和度微调参数、第二饱和度微调参数及第三饱和度微调参数均为0。
如果饱和度对比单元42判断该实际饱和度值小于该预定饱和度值，则饱和度对比单元42减小第一预定饱和度参数和第三预定饱和度参数，并增大第二预定饱和度参数，直至该实际饱和度值不小于该预定饱和度值，而后利用第一预定饱和度参数和第三预定饱和度参数的减小量分别对应作为第一饱和度微调参数和第三饱和度微调参数，并利用第二预定饱和度参数的增大量作为第二饱和度微调参数。应当理解的是，这时，Δβ1和Δβ3为负值，Δβ2为正值。
