Description

M244480 五、創作說明α) 【新型所屬之技術領域】 ^ 本創作係有關投影顯示裝置,尤其關於投影機中不 同色彩模式選擇驅動裝置。 【先前技術】 隨著科技的蓬勃發展,投影機已運用到各種領域, 例如業務簡報或家庭劇院使用,業務簡報型的需求是以 高亮度為主,而家庭劇院型為符合播放影片則以高色彩 飽和度為主。M244480 V. Creation Instructions α) [Technical Field to which the New Type belongs] ^ This creation is about a projection display device, especially a different color mode selection drive device in a projector. [Previous technology] With the rapid development of technology, projectors have been used in various fields, such as business briefings or home theaters. The needs of business briefings are mainly high brightness, while home theaters are high in order to meet the needs of playing movies. Color saturation is dominant.

如圖1所示,習知投影顯示裝置1 0係由光源1 1產生一 照明光束,光束經由反射罩(r e f 1 e c t 〇 r ) 1 2 ,聚集反射至 一色輪1 3 ( c ο 1 o r w h e e 1 ),色輪1 3設有系列各色濾光片 ,當光束通過色輪13時,即轉換成有色光束,再通過光 學積分柱1 4,將有色光束均勻化後,藉由照明透鏡組1 5 照射至光閥16(Light valve),然後由光閥16形成影像光 束選擇性投射入成像鏡頭1 7,最後投影至螢幕1 8上。 其中色輪13為紅(Red, R )、綠(Green, G)、藍 (Blue, B)及白(W,white)色等濾光片 131 、132、133、 % 1 3 4 ( S e g m e n t )所構成一圓環形,並藉由馬達1 3 5帶動濾光 片1 3 1 、1 3 2、1 3 3、1 3 4高速旋轉,當光束依序通過濾光 片1 3 1 、1 3 2、1 3 3、1 3 4後,快速產生紅、綠、藍、白之 不同原色光,並照射至光閥1 6 ,由光閥1 6於短時間内精 確選擇投射各色光比例,以決定色彩對比。 由於習知投影顯示裝置1 0為單一色輪1 3,當預定作 為業務簡報時,係增大白濾光片面積,增加白光照射時 M244480 五、創作說明(2) 對減少R、G、B色濾光片之 盤.造成色彩飽和度不佳。 用時,則增大R、G、B各色 光片犧牲部分亮度,減少 像色彩飽和度。因此單一 種相反需求之架構,只能 一,或介於中間設計或將 度,以達成一機兩用。但 膠粘的光學玻璃材質濾光 又在高速旋轉與間歇性移 穩定旋轉,更易破裂,同 亦不足於振動或撞擊後獲 閥選擇投射各色光比例之As shown in FIG. 1, the conventional projection display device 10 generates an illumination light beam from the light source 11, and the light beam is collected and reflected to a color wheel 1 3 (c ο 1 orwhee 1) through a reflection cover (ref 1 ect οr) 1 2. ), The color wheel 1 3 is provided with a series of color filters. When the light beam passes through the color wheel 13, it is converted into a colored beam, and then passes through the optical integration column 1 4 to uniformize the colored beam, and then the illumination lens group 15 is used. The light is irradiated onto the light valve 16, and then the image beam formed by the light valve 16 is selectively projected into the imaging lens 17 and finally projected onto the screen 18. Among them, the color wheel 13 is red (Red, R), green (Green, G), blue (Blue, B) and white (W, white) color filters 131, 132, 133,% 1 3 4 (S egment ) Constitutes a circular ring, and the filter 1 3 1, 1 3 2, 1 3 3, 1 3 4 is rotated at a high speed by a motor 1 3 5 when the light beam sequentially passes through the filters 1 3 1, 1 After 3 2, 1 3 3, 1 3 4, the different primary colors of red, green, blue, and white are quickly generated and irradiated to the light valve 16. The light valve 16 accurately selects the proportion of light in each color to be projected in a short time. To determine color contrast. Because the conventional projection display device 10 is a single color wheel 13, when it is scheduled as a business briefing, the area of the white filter is increased, and the white light is illuminated. M244480 V. Creation instructions (2) To reduce the R, G, and B colors Filter disk. Poor color saturation. When in use, increase the R, G, and B color film sacrifices part of the brightness, reducing the image color saturation. Therefore, a single structure with opposite requirements can only be designed in one, or in the middle, or to achieve a dual purpose. However, the glued optical glass filter also rotates stably at high speeds and intermittent movements, and is more susceptible to cracking. It is also not enough to obtain the proportion of light colors that the valve chooses to project after vibration or impact.

間以提升亮度,但此種方式相 照射時間,導致三色彩較不鮮 反之,當預定作為家庭劇院應 渡光片,並刪除或縮小白光渡 白光相對照射時間,以提升影 色輪之投影顯示裝置,對此兩 在高亮度與高色彩飽和度中擇 色輪間歇性移離光路徑增加亮 在高功率光源照射下,色輪上 片,本身受熱高溫已易脆化, 動慣性甩動下,不僅無法獲得 時為使色輪易於移動,其結構 得穩固精確定位,進而影響光 精嫁性。 【新型内容】 本創作之目的在提供一種色彩選擇驅動裝置,藉穩 固移動之結構,確保色輪在移動慣性、振動或撞擊後不 移位,且避免破裂。In order to increase the brightness, but the time of irradiation in this way, the three colors are less vivid. When it is scheduled to be used as a home theater light, and delete or reduce the relative exposure time of white light and white light, to improve the projection display of the shadow color wheel This device is used for high brightness and high color saturation. The color selection wheel is intermittently moved away from the light path to increase brightness. Under the illumination of a high-power light source, the color wheel is placed on the film. , Not only in order to make the color wheel easy to move when it is not available, its structure must be stable and accurate positioning, and then affect the photon fineness. [New content] The purpose of this creation is to provide a color-selection driving device that, with a stable moving structure, ensures that the color wheel does not shift after moving inertia, vibration, or impact, and avoids rupture.

本創作之另一目的在提供一種色彩選擇驅動裝置, 精確驅動色輪定位,以獲得最佳色彩對比。 本創作之再一目的在提供一種色彩選擇驅動裝置, 可切換不同色彩飽和模式之色輪,以擴大適用範圍。 為達成上述之目的,本創作係於色彩選擇驅動裝置Another purpose of this creation is to provide a color selection driving device that precisely drives the color wheel positioning to obtain the best color contrast. Another purpose of this creation is to provide a color selection driving device that can switch the color wheels of different color saturation modes to expand the scope of application. To achieve the above purpose, this creation is based on a color selection drive

模式,以選擇色輪2 6為例(即色彩飽和模式),藉由馬達 2 2 (例如步進馬達等)驅動螺桿2 3定點旋轉,使嚙合之齒 桿2 5 2沿著螺桿2 3以均緩速度移動,進而使齒桿2 5 2帶動 滑座2 5跟著移動,由於滑座2 5受限於支撐之上下滑桿 2 1 5、2 1 6,使滑座2 5在上下穩固支樓下進行均緩速度移 動,避免滑座2 5上色輪2 6、2 7破裂.,且配合感應器2 4與 感應塊2 5 4偵測定位,將色輪2 6精確切入光路徑定位,達 成播放色彩飽和模式之選擇。然後啟動播放模式之轉動 馬達2 6 1旋轉色輪2 6 ,並藉由相位偵測單元2 8彳貞測轉動馬 達2 6 1之轉動角度,確認何種色濾光片正切入光路徑,使 光閥精確處理各色光比例,以提供最佳色彩對比。反 之,如選擇色輪2 7 (即高亮度模式),僅係馬達2 2反向旋 轉,其餘作動方式與選擇色彩飽和模式相同,以提供高 亮度畫面。 本創作之實施例雖以兩色輪2 6、2 7為例作說明,但 同理亦可由此推知,滑座2 5上可設置複數個以上色輪, 以獲得更多色彩模式之選擇;此外,本創作雖以並排平 移色輪方式,切換不同彩色模式之色輪,同理色輪亦可 以弧狀或環狀排列方式切入光路徑。Mode, taking the selection of the color wheel 26 as an example (ie, the color saturation mode), the motor 2 2 (such as a stepper motor, etc.) drives the screw 23 to rotate at a fixed point, so that the meshing tooth bar 2 5 2 follows the screw 23 Both are moving at a slow speed, so that the rack 2 5 2 drives the slide 2 5 to follow. Since the slide 2 5 is limited by the support, the slide bar 2 1 5 and 2 1 6 make the slide 2 5 stable up and down. Downstairs are moving at a slow speed to avoid the slide 2 5 and the color wheel 2 6 and 2 7 from breaking, and cooperate with the sensor 2 4 and the sensor block 2 5 4 to detect and position, and accurately position the color wheel 2 6 into the light path. , To achieve the choice of playback color saturation mode. Then start the rotation motor 2 6 1 in the playback mode to rotate the color wheel 2 6, and measure the rotation angle of the rotation motor 2 6 1 with the phase detection unit 2 8 to determine which color filter is tangent to the light path, so that The light valve precisely processes the light ratio of each color to provide the best color contrast. Conversely, if the color wheel 2 7 is selected (that is, the high-brightness mode), only the motor 2 2 is rotated in the reverse direction, and the remaining operation methods are the same as those of the color saturation mode to provide a high-brightness picture. Although the embodiment of this creation uses two color wheels 26, 27 as examples for illustration, it can be inferred from the same reason that more than one color wheel can be set on the slider 25 to obtain more color mode options; In addition, although this creation uses the side-by-side panning color wheel method to switch the color wheels of different color modes, the color wheel can also cut into the light path in an arc or ring arrangement.
