M293456 八、新型說明： 【新型所屬之技術領域】 丰創作係關於 =投影，並具"平板電 【先前技術】 一般利用投影設備使呈現出投影影像之方式主要可 分為背投影與外投料财式。背投料係將投影設備裝 置於投影螢幕之後方，使觀賞者由投影螢幕前方觀察所投 影之影像，而外投影則係將投影設備裝置於投影螢幕之前 方’使觀賞者亦由投影螢幕前方觀察所投影之影像。背投 影方式由於具有空間設置上的限制，因此在放大比例上較 無法滿足大螢幕之需求，且其在投影屏幕之特性上有較高 之要求，故在市場上較不普遍。相較之下，外投影方式僅 需有一可反射之牆面或布面，即可進行放映，無論是屏幕 之要求或是投影裝置所需之設置空間皆較具彈性，因此成 本較低，裝設上相當方便，故較為普及。 然而，由於外投影方式之投影影像，係透過投影屏幕 之反射作用而呈現，故若欲觀賞到亮麗清晰之畫面，除投 影裝置亮度、色彩與解析度等規格之要求外，最重要的就 是投影屏幕所呈現之投影品質與投影效果。一般而言，增 益、觀察視角與擴散方式係判定投影屏幕品質好壞相當重 ⑧ M293456 要的幾個技術指標。增益係指投影屏幕反射投射光之能 力，倘其指數愈高表示其反射能力愈好，則愈能表現出高 亮度的晝面。觀察視角則指由屏幕中心向外侧偏移之觀察 角度，當觀察亮度降至50%時’該角度即為視角，視角愈 大，則可較不受觀察角度之限制，而較能觀察到足夠亮度 之晝面。此外，擴散方式是指投射光反射後之光徑擴散方 式，若擴散度小則投射光反射性佳，畫面較亮也較清晰； 相反的，擴散度大則投射光反射範圍大，雖晝面較為柔和 φ 且較能避免其他光線之干擾，但亮度、清晰度則較差。目 前市面上，最常使用且成本較低之投影屏幕主要為白塑布 材質，其他則有玻璃珠投影幕、銀色珍珠投影幕等。白塑 亦投影屏幕其增益值一般接近0.9,故在亮度的呈現上並不 理想，且其光擴散度較高，在晝面清晰度上並不盡人意， 故無論在增益或擴散方式上仍有相當大的改善空間，因 此，如何將屏幕所呈現之亮度、清晰度調整最適當，即係 其材質與結構設計上最重要之考量要素。 # 此外，目前利用於投影之投影屏幕，皆係將投影幕捲 收於一捲收盒中，若欲使用時再以人工或電動的方式，將 該投影幕垂放伸展。故一般投影幕使用時係藉其本身重量 而呈現自然垂放之狀態，因此，若有風吹或空調系統之吹 拂’不受固定之投影幕將產生晝面晃動之狀況。雖然其^史 有能夠維持投影幕平整、穩定之荷重桿，但屏幕仍舊^法 避免地存有不夠平整之處，對於晝面呈現之品質亦會產生 相當私度的破壞。 M293456 【新型内容】 為改善習知投影屏幕增益性與光擴散度，使能相配合 而呈現出最佳之顯不晝面，並同時避免習知投影幕自然垂 放下所產生畫面平整性與穩定料足之缺失，本創作將提 供一種在習知基層材上’塗佈有反射層或光擴散層之投影 幕，使投影幕增加其反射效果而提升其亮度的呈現，並透 過光擴散層之光線均勻化作用，一方面兼顧畫面的清晰度 與柔和度，另一方面則可避免外在光線之干擾，而能以最 逼真的方式完整呈現投影裝置所投射出之優質影像。同 時，本創作中，係將投影幕穩固地裝設於一類似目前平板 電視之邊框中，因此投影幕能夠平整、穩定的呈現投影書 面，而配合邊框構型之設置，更使觀賞者相當於收看平板 電視之畫面顯示，故藉由本創作可使整體之投影畫面在顯 示品質與顯示效果上都有相當優異之表現。 本創作之外投影式薄膜電視，包括··一屏幕，該屏幕 包括有一四邊形邊框，該邊框内則裝設有一投影幕；以及 一投影裝置’該投影裝置係設置於該屏幕前方一預定位置 處，該投影裝置投影時，該屏幕可將所投射之影像經由反 射作用，讓使用者於設置有該投影裝置之同侧觀賞到投影 影像。其中，4邊框可進一步接設有至少一腳架、壁掛架 或吊掛架，而依需求设置於適當的處所。此外，該投影幕 則包括有一基材層，該基材層表面並塗佈有一反射層，該 反射層係面向該投影裝置。該反射層可為一鎂碳酸化合物 層，或是於一透明樹脂層中分佈有反射薄片，藉以增加原 M293456 讓使 亦可將 使進一步改善M293456 VIII, new description: [New technology field] Feng creation department about = projection, and " tablet power [previous technology] Generally use projection equipment to make the projected image is mainly divided into back projection and external feeding Financial style. The back-feeding device places the projection device behind the projection screen, so that the viewer observes the projected image from the front of the projection screen, and the external projection connects the projection device to the front of the projection screen to make the viewer also front of the projection screen. Observe the projected image. Due to the limitation of space setting, the rear projection mode is less able to meet the needs of large screens in terms of magnification ratio, and it has higher requirements on the characteristics of projection screens, so it is less common in the market. In contrast, the external projection method only needs to have a reflective wall or cloth surface for screening, whether the requirements of the screen or the installation space required by the projection device are relatively flexible, so the cost is low. It is quite convenient to set up, so it is more popular. However, since the projected image of the external projection mode is presented through the reflection of the projection screen, if the image is to be bright and clear, in addition to the specifications of the brightness, color and resolution of the projection device, the most important is the projection. The projection quality and projection effect presented by the screen. In general, the gains, viewing angles, and diffusion methods are important for determining the quality of the projection screen. 8 M293456 Several technical indicators. Gain refers to the ability of the projection screen to reflect the projected light. If the index is higher, the better its reflection ability, the better the high brightness surface. The viewing angle refers to the angle of observation from the center of the screen to the outside. When the brightness is reduced to 50%, the angle is the angle of view. The larger the angle of view, the less the viewing angle is, and the more observable. The face of brightness. In addition, the diffusion method refers to a method of diffusing the light path after the reflected light is reflected. If the degree of diffusion is small, the reflectivity of the projected light is good, and the picture is brighter and clearer. Conversely, if the degree of diffusion is large, the range of reflection of the projected light is large, although the diffuse surface is large. It is softer φ and can avoid interference from other light, but the brightness and sharpness are poor. Currently, the most commonly used and low-cost projection screens are mainly white plastic cloth materials, while others have glass bead projection screens and silver pearl projection screens. The projection value of the white plastic projection screen is generally close to 0.9, so it is not ideal in the display of brightness, and its light diffusivity is high, which is not satisfactory in the definition of the surface, so it is still in the gain or diffusion mode. There is considerable room for improvement. Therefore, how to adjust the brightness and sharpness of the screen is the most important factor in the material and structure design. # In addition, the projection screen currently used for projection is to roll the projection screen into a roll-up box, and if it is to be used, the projection screen is vertically extended by manual or electric means. Therefore, when the projection screen is used, it is naturally suspended by its own weight. Therefore, if there is a blowing of the wind or the air conditioning system, the projection screen will not be shaken by the fixed projection screen. Although the history has a load-bearing rod that can maintain the flat and stable projection screen, the screen still avoids the lack of flatness, and the quality of the surface is also quite private. M293456 [New Content] In order to improve the gain and light diffusivity of the conventional projection screen, it is possible to match and display the best display, and at the same time avoid the flatness and stability of the screen produced by the conventional projection screen. In the absence of material, the present invention will provide a projection screen coated with a reflective layer or a light diffusing layer on a conventional base material, so that the projection screen increases its reflection effect and enhances its brightness, and transmits through the light diffusion layer. The uniformity of light, on the one hand, the clarity and softness of the picture, on the other hand, avoids the interference of external light, and can fully display the high-quality image projected by the projection device in the most realistic way. At the same time, in this creation, the projection screen is firmly installed in a frame similar to the current flat-panel TV, so the projection screen can be flat and stable to present the projection, and the frame configuration is more suitable for the viewer. By watching the screen display of the flat-panel TV, the overall projection screen can be performed with excellent performance in both display quality and display effect. A projection type thin film television other than the present invention, comprising: a screen comprising a quadrangular frame, the frame is provided with a projection screen; and a projection device is disposed at a predetermined position in front of the screen When the projection device is projected, the screen can reflect the projected image through reflection, so that the user can view the projected image on the same side of the projection device. Wherein, the 4 frame can be further connected with at least one stand, a wall mount or a hanging frame, and is disposed in an appropriate place according to requirements. In addition, the projection screen includes a substrate layer, and the substrate layer is coated with a reflective layer facing the projection device. The reflective layer may be a magnesium carbonate layer or a reflective sheet distributed in a transparent resin layer, so that the original M293456 can be further improved.
