LCD液晶显示器的颜色特性研究

Analysis on color characterization and calibration of LCD

定量描述了液晶显示器的颜色特性以及对显示彩色图像的影响。在实验测量的基础上,得到了LCD液晶显示器的颜色特性数据。以3D LUT方法建立了设备颜色空间RGB与标准颜色空间L a b 之间的近似转换模型。通过分析比较它们的色域边界特性,了解了与CRT显示器颜色色域的差异以及影响显示彩色图像时颜色失真的特点。

The characterization and calibration of color LCD are important in cross-media color image reproduction. Based on practical measurements, the color character of a LCD is analyzed, and an approximate transform model between RGB space and L* a* b* space of the LCD is established. Starting from this model, an RGB->L*a*b* look up table, a predictive searching- method for L* a* b* to RGB conversion are proposed. The gamut difference between LCD and CRT is also discussed.
