Description of the invention: [Technical field to which the invention belongs] The present invention relates to-a kind of monolithic * valve projection split, and in particular to-it can be taken into account in the narrative style, taking into account image pairs _ Monolithic light valve projection device. [Previous technology] In recent years, the volume is large and the "heavy Cathode Ray Tube (CRT) projection device has gradually been used by liquid crystal projection devices and digital light processing (DLP) projection devices. Was replaced. These products are thin, light, and highly portable, and can be directly linked to digital products to project and display images. In the case of various manufacturers constantly launching cheap and competitive products and increasing their additional functions, these products have been gradually expanded to ordinary homes for movie appreciation, in addition to occasional presentations in companies, schools and other public places. The use of presentations requires high brightness. The use of movies requires high saturation, so 'to make the projector can be used for high brightness and high saturation at the same time' is a future trend. FIG. 1 is a schematic structural diagram of a conventional single-chip light valve projection device. Please refer to FIG. 1. The conventional single-chip light valve projection apparatus 100 includes a light source 110, a projection lens 12G, an imaging unit ^ 13G, and a control unit / element iso. Among them, the light source 11G is adapted to provide a light beam 112. In addition, the projection unit 120 is disposed behind the light source 110 and is located in the single-chip light valve projection apparatus 100 described above in the transmission path of the light beam 112. The imaging unit 130 is configured between 1243275 13944twf.doc between the silk 110 and the projection lens 12 and is located in the beam m's transmission path = up. The known imaging unit 130 includes a color wheel 132 and a digital micromirror device 134. The digital micromirror device 134 is disposed behind the color wheel 132 and located on the transmission path of the light beam 112, and the control unit 150 is used for synchronous control. The color wheel 132 and the digital micromirror device 134. The control unit 150 includes a color wheel driver 156 and a digital micromirror device driver 1 ^. The digital micromirror device driver 152 is electrically connected to the digital micromirror device 134, and the color wheel driver 156 is electrically connected to the color wheel 132. In addition, the digital micromirror device driver 152 and the color wheel driver 156 in the control unit 150 are used to control the digital micromirror device 134 and the color wheel 132 simultaneously. As described above, the light beam 112 provided by the light source 110 is transmitted to the color wheel 132 of the imaging unit 130. Next, the color wheel driver 156 in the control unit 150 controls the color wheel 132 electrically connected to the color wheel driver 156 to sequentially divide the light beam 112 into light beams 112 of different colors. Next, these light beams 212 are sequentially incident on a digital micromirror device 134 having a plurality of pixel units, and these pixel units are controlled by a digital micromirror device driver 152 electrically connected to the digital micromirror device driver 152 so that they are in an ON state or respectively. FF status. The pixel unit in the ON state causes the light beam 112 to be reflected to the projection lens 120, and the pixel unit in the 0FF state causes the light beam 112 to deviate from the projection lens 120. After that, the projection lens 120 projects these light beams 112 (= images) processed by the digital micromirror device 134 onto the screen S. As mentioned above, the conventional single-chip reflective projection device 100 will use a red light filter block (R), a green light filter block (G), and a blue light filter block (B '). The color wheel 132, however, due to the boundary between the filter blocks on the color wheel 132, 1243275 13944twf.doc ίΓΓΓΓ light, the color saturation b of the projected image is poor. In addition, since there is still stray light on the dark day surface (the pixel units of the digital micromirror device are all OFF), the contrast of the projected image becomes low. Daylight brightness Dark daylight brightness contrast High brightness mode 1000 (Lux) 1 (Lux) 1000 High saturation mode 500 (Lux) 1 (Lux) 500 In order to increase the brightness of the image, the single-chip reflective projection device 100 can Various modes with high brightness and high saturation. In the conventional technology, a color wheel with a red filter block, a green filter, a light block, a blue light block, and a white filter block (W) is used. 132, to increase the brightness of the image, but this will reduce the color saturation; therefore, when the high saturation mode is to be used, the digital micromirror device driver 152 will not process part or all of the light beams that pass through the white filter block, or Does not process part or all of the light beams that pass between the filter blocks to increase the saturation; in the above manner, in the high-brightness mode, the daylight surface brightness is the beam brightness of R, G, B, and W, and the dark daylight surface brightness It is the stray light brightness generated by the R, G, B, and W beams; while in the high saturation mode, the daylight brightness is R, G, and B, and the dark daylight brightness is still generated by the R, G, B, and W beams. Stray light brightness; therefore, in high saturation mode Day surface luminance decreases, there remains a stray light W generated during its dark screen, without changing the surface luminance dark day, will therefore in comparison to reduce high saturation mode. The following provides a data to more clearly show the differences in slope ratios. Therefore, the above-mentioned projection devices cannot be used in various modes, such as: 1243275 13944twf.doc ^ degrees or high saturation 'all provide better contrast.

The beam blocking member 244 may be disposed between the light source 21 〇12 1243275 13944twf.doc and the imaging unit 230, as shown in FIG. 4A. It is arranged between the light source 210 and the color generating element 232. In addition, as shown in FIG. 4B, the light beam interrupting member 244 may be disposed between the imaging unit 230 and the projection lens 220, for example, as shown in FIG. 4B between the light valve 234 and the projection lens 220. In addition, the light valve interrupter 244 may be disposed in the projection lens 220 as shown in FIG. 4C or between the projection lens 220 and the screen S as shown in FIG. 4D. Please refer to FIG. 2 again. For example, the single-chip light valve projection device 2000 of this embodiment further includes a control unit 250 for synchronously controlling the color generating element 232, the light valve 234, and the beam blocking module 24. The control unit 25 is, for example, a circuit board, which includes, for example, a light valve driver 252, a braking element driver, 254, and a color generating element driver 256. The light valve driver 252 is electrically connected to the light valve 242. In addition, the brake element driver 4 is t-connected to the brake element 246 to control the beam interrupter 244. In addition, the color generating element driver n 256 is connected to the color generating element 232, in which the light valve driver 252, the braking element driver 254, and the element driving H 256 are controlled by a step-by-step control and color generating element 232.

In addition, the configuration is: 2: the light sensor 242 next to the generating unit 232 * senses the color generation _ W-shaped evil ′ and transmits a synchronization signal representing the state of the color generating unit 232 to the control material 25. Next, these light beams will be transmitted in sequence. = Blockage %%. At this time, the control unit 250 will control the braking element 246 by the braking element driver 254 according to the synchronization of the light sensor. The light valve blocking member 244 is controlled to block the light beam 212 passing through a certain time. In this embodiment, for example, the white light tear light block W and the light beam 212 may be blocked, or for example, the stray light caused by the boundary of each light block may be blocked to increase the color saturation of the image. In this embodiment, for example, the light beam 212 passing through the white light filter block w and the stray light caused by the junction E of each filter block can be blocked to simultaneously perform color saturation and contrast. Then, these are not interrupted by a light valve 234. The light valve 234 includes, for example, a liquid crystal display (①), a digital micromirror device (DMD), or a reflective single crystal silicon liquid crystal display (LCOS). The light valve 232 of this embodiment is described by taking a digital micromirror device having many pixel units as an example. The light valve 232 is controlled by the light valve driver 252 which is electrically connected to the pixel units, so that the pixel units are in an ON state or an OFF state, respectively. The pixel unit in the ON state causes the light beam 212 to be reflected to the projection lens 220, and the pixel unit in the OFF state causes the light beam 212 to deviate from the projection lens 220. After that, the projection lens 22 will project these light beams 212 (images) processed by the light valve 232 on the glory screen s. 14 1243275 13944twf.doc When the beam interruption module 240 cuts out the transmission path of the beam, the image is displayed on the screen. Please refer to the figure. The beam 1 provided by the light source ⑽ will be transmitted to the color wheel 132, then The color wheel driving unit 156 in the control unit 15 will control the color wheel 132 electrically connected to the color wheel 132 to sequentially divide the light beam 112 into light beams 112 of different colors. Next, these light beams 212 will be incident sequentially. The digital micromirror device 13 of the plurality of pixel units and the digital micromirror device shaft 152 electrically connected to the digital micromirror device 13 control the pixel units, and they are in a QN state or a clear state. In the ⑽ state, the prime unit will cause the light beam 112 to be reflected to the projection lens 120, and the pixel unit which presents 0FF will cause the light beam 112 to deviate from the projection lens. After that, the projection lens 12G projects the light beam U2 (image) processed by the digital micromirrors on the screen s. f. The embodiment uses the beam interruption module 24o to make the single-chip light valve projection device and various scene modes, such as high-brightness mode (presentation mode) and ancient mode (film mode) mode, all have high contrast. When a higher image is required, such as a presentation, the beam mode of this single-chip light valve projection device 200 can be used. In this mode, the light valve blocking module 240 will cut out the beam 2U ^, so that red, green, and blue And white light, ^ = ^ makes the projected image (not shown) have high brightness. Electricity-Japan = 2 When you want to read the same color and degree of contrast, for example, see W T, you can switch this single-chip light valve projection device 200 to the ancient model mouth bribe group 24.
