Abstract:
The principles of the color display and the color temperature adjusting for the single panel DLP optical engine were discussed,combined with the fundamental theory of the colourometry and the character of the DLP optical engine. The formula to calculate the colorimetric characters for the single-panel DLP optical engine was given. By using the formula on the optical engine of the AMOITM DL52HWT rear- projection TV the chromaticicity coordinates of the primary colors,the white balance,the color temperature of the white balance and the color recurrent errors were calculated. Finally, the formula was proved with the analysis of the calculation results.[著者文摘]
