  • Patent number: 6799851
    Abstract: Disclosed is an optical projection system having a simple structure by scrolling a light of each wavelength efficiently on a panel by preventing a color shift by adjusting a width of a color band on a color drum surface properly. The present invention includes the color drum outputting an incident light through a predetermined number of color bands on a drum plane to display wherein a light outputted from an end of a light projecting plane outputting the incident light has an incident angle equal to or smaller than 30° on the color band. Therefore, the present invention minimizes the influence of the color shift, provides an incident light in the scroll optical system effectively using the simple and inexpensive color drum, and prevents the degradation of image.
