In this technology, digital micromirror wafers are used to replace the liquid crystal panels in traditional LCD projectors that are responsible for presenting images. Many tiny movable lenses on digital micromirror wafers use driving electrodes to control the tilt angle and deflection time of the movable lenses, and then switch the reflection direction of the light to project images from the lens. As shown in FIG. 1, a color wheel for generating colors is provided in the DLP type projector. The color wheel 1 mainly includes a motor u, a cover sheet 12, and a color filter and a light sheet 13. The cover 12 and the color filter 13 are fixed to the motor η. Here, the motor 1H is mainly composed of a shaft cover and a motor body 112. In addition, the color wheel 丨 may further include a certain bit 14 ′ and a row of wires 15. The positioning member 14 is used to fix the color wheel i to 1242102, and the donkey 1❿ cable 15 is connected to a driver.

The color dowel sheet 13 used in the industry is fixed to the motor 11 ± by using several pieces of different colors with adhesive glue. Because the rotation speed of general 2 is higher than the side rotation, when the rotation center deviates from the rotation field, the heat-resistant temperature of the adhesive is about 15 ° t: to C '. In ordinary image projection systems, the temperature generated by fine heating is 0 C. Up to 200 C, so the adhesive is prone to occur at this temperature, which may cause the adhesive force between the color filter 13 and the motor η
