A COLOR WHEEL FOR MD PROJECTION DISPLAY

摘要

The invention provides a color wheel for Micro-Device (MD) projection display. The color wheel of the invention includes a color filter with different colors divided on the circumference thereof, a driving motor rotating a rotor with the color filter assembled thereinto, and a filter adhesion layer fixing the color filter to the carrier by an adhesive applied on the overlapping region of the carrier and the color filter. The color wheel also includes a holder having a fixing part to maintain compressive stress offsetting tensile stress generated at the filter adhesion layer. The invention minimizes tensile stress at the adhesion part for fixing the color filter, increasing the adhesive force between the adherent and the adhesive, thereby allowing firm fixing of the color filter to the driving motor without using an adhesive.
