VI. Description of the invention: [Technical field of the invention] [0001] The present invention relates to a color wheel, and more particularly to a color wheel which can optimize the color performance effect. [Prior Art] [0002] At present, projectors are mainly divided into LCD type and DLP type (Digital Light Processing), which make DLP projector adopt DMD (Digital Micromirror Device) microlens reflection technology and adopt color wheel (Color Wheel) to complete the separation and processing of colors. [0003] In the DMD projection system, the white light emitted by the light source is focused on the color wheel by a focusing lens, and the color wheel is mainly composed of a combination of color filters such as red, green, and blue, and the color filter is driven by a high speed motor. Turn and move to separate the white light, and then emit a specific color beam onto the DMD surface. The DMD surface consists of small mirrors corresponding to the number of pixels. These small mirrors rotate according to the control of the video signal. When the small mirror rotates to its reflected beam through the lens of the projector, it indicates that the pixel is turned on when small reflection When the mirror is rotated until its reflected beam is off the lens of the projector, it indicates that the pixel is off, and the time of opening and closing is greater than the brightness of the pixel. When red light hits the surface of the DMD, the lens on the DMD rotates the small mirrors on or off according to the red video signal, so that the reflected beam that needs to be displayed is projected onto the large screen through the lens of the projector, green and blue light and video. The signal is also working like this, and the red, green and blue images that are collectively projected by the human visual system see a full-color image. Please refer to FIG. 1 , which is a color wheel 100 of the prior art.

The filter group 10 is fixed on the support member 20, and the motor 26 drives the support member 20 to rotate, thereby driving the tri-color filter group 10 to rotate. The time scale 24 is used to help the projector system recognize the current three. The position of the red filter 12, the green filter 14 and the blue phosphor film 16 in the color filter group 10. [〇〇〇5] The time stamp 24 is disposed on the side wall 23 of the support member 20 and correspondingly filtered. When the slice group 1 is a red filter 12 segment, the sensor wafer 34 of the sensor 30 uninterruptedly emits the light beam 17 onto the sidewall 23 of the support member 20, and when the light beam 17 is just incident on the time stamp 24, The beam 17 is sucked by the time stamper, and the beam 17 is not reflected to the sensor crystal 3 peak if of the sensor 30, and the solid detector 30 knows · : -V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Since the position between the color filters of the filter group 1 of the color wheel 1 is distributed beforehand, the processor 25 knows the position of a monochromatic filter to infer the entire filter. The rotational position of the light film group 'so that the processor 25 can accurately switch the timing of each color. It can be seen that in the high-speed rotating filter group 1 ' 'the recognition of the current color of the color wheel 1 投影 by the projector directly affects the imaging Color quality. [0006] Only the projector is a high-brightness product that produces a lot of stray light beams 18 inside the casing. The prior art sensor 3 is used to emit the light beam 17 and sense the reflected light beam. The sensor wafer 34 is directly exposed to the outside world.

The through hole 82 of the light blocking member 80 is sized to shield the signal processing device from the light emitting device 37 of the sensor wafer 64 to the side wall 9.3 of the support member 90 and the light beam 37 can be reflected to the sensor wafer 64 without being shielded. It is appropriate. The material of the light blocking member 80 may be an opaque plastic. Preferably, the color of the light blocking member 80 may be black or the surface is black to absorb stray light. In a practical application, the light blocking member 80 may be fixed to the first side 62 of the casing 63 in a screwing manner, or the light blocking member 80 may be integrally formed with the casing 63. Of course, the light blocking member 80 can also be four light blocking sheets. The width of the four light blocking sheets is wider than the width of the housing 63 of the sensor 60. 096137482 Form No. A0101 Page 10 / Total 17 Page 0993457635-0 1339311 ι___ On December 23, 099, the replacement page is equal. The four light blocking sheets are respectively disposed at corresponding positions of the side frames of the housing 63 of the sensor 60. When the housing 63 of the sensor 60 has a circular structure, the light blocking member 80 is correspondingly formed into a circular shape, and the shape of the light blocking member 80 changes correspondingly according to the structural shape of the sensor 60, and It is not limited to this embodiment. [0020] The working principle of the present invention will be described in detail below in conjunction with the above structure: when the motor 70 rotates, the support member 90 and the filter set 50 disposed on the second surface 92 of the support member 90 are synchronously rotated, and at the same time, The transmitting device of the sensor chip 64 of the sensor 60 continuously emits the light beam 37, and the signal processing module of the sensor chip 64 receives the reflected beam 37, and when the position of the support member 90 is turned to the time mark When the alignment beam 37 is positioned, the time stamp 94 absorbs the reflected beam 37, so that the sensor crystal, the signal processing device of the chip 64. does not sense the reflected light signal. In this embodiment, the position of the time stamp 94 corresponds to the position of the red filter 52 segment. Therefore, the signal processing device of the sensor chip knows the rotational position of the multicolor filter. The position between the color filters of the filter set 50 is previously distributed, and the processor 55 knows the position of a monochromatic filter to infer the rotational position of the entire filter set 50. The light blocking component 80 is disposed on the housing 63 of the sensor 60 to shield the stray light from the sensor wafer 64, so that the sensitivity of the signal processing device of the sensor chip 64 is improved, and the multi-color is more accurately The rotational position of the filter set 50 is communicated to the processor 55 and serves as a basis for controlling the multi-color filter set 50 to be synchronized with the DMD (not shown) and to modulate the light to achieve accurate color light synthesis. [0021] The housing of the sensor of the color wheel is provided with a light blocking element for blocking stray light from hitting the sensor chip of the sensor, and the 096137482 form number A0101 is improved. 11 pages / total 17 pages 0993457635-0 1339311
