New description: [New technical field] This creation is about a projection board, and in particular, it relates to a crystal projection board with a bright projected image and a bright color palette. [Prior Art] With the advent of projectors, teaching or presentation work can be performed more quickly and easily. Thanks to advances in technology, it is possible to connect a personal computer or a pen-type computer to receive digital image data stored in the computer, and a color projector that projects the image onto the projection board has emerged. Recently, with the development of electronic technology, the quality of digital images such as color and resolution has also progressed considerably. Therefore, how to realistically display the image projected on the projection board is a major issue in the technology of projectors and projection panels. [New content] In view of this, the purpose of the present invention is to provide a projection panel that can realistically display an image projected on a projection screen. Another object of the present invention is to provide a projection panel whose projected image is bright and colorful. To achieve the above and other objects, the present invention provides a projection panel that is adapted to display an image projected by a projector. The projection panel comprises: a transparent substrate and a layer of metal particles, wherein the 'transparent substrate is flat and has a first plane and a second plane opposite the first plane. The metal particle layer is uniformly attached to the first plane of the transparent substrate for reflecting and visualizing the image projected by the projector. 5 M317591 ^ In one embodiment, in order to enhance the visual effect of the projection panel, a glass, a plastic, a film or an acrylic is used as a transparent substrate to which a metal particle layer is attached, thereby achieving a crystal-like appearance. Visual effects. In one embodiment, silver powder or powder is used as a layer of metal particles to achieve the purpose of reflecting and visualizing the image projected by the projector. Here, the metal particle layer is adhered to the first plane of the transparent substrate by a binder such as a resin. In another embodiment, the metal particle layer is applied by a plastic film to adhere to the first plane of the transparent substrate. > In an embodiment, the transparent substrate further comprises an atomization treatment layer uniformly attached to the second plane, and the atomization treatment layer may have a light transmittance of between 40% and 90%. Between five. The thickness can range from 1 micron to 4 microns. The above and other objects, features, and advantages of the present invention will become more apparent and understood. 4 is a schematic view of a projection and shadow plate according to a preferred embodiment of the present invention. The projection panels 10, 20, and 30 can provide a projection (not shown) projection, and the images are clearly and brightly displayed on the projection panel 10, 20 or 30, and the displayed images are vivid and bright. According to the actual use efficiency of the projection panel 10, 20 or 30 of the present invention, the image projected by the projector can be clearly and clearly displayed even in an environment where the indoor lighting is not turned off. The projection panel 10, 20 or 30 is basically constituted by a transparent substrate 11 such as glass, plastic, film or acrylic. The purpose of using the transparent substrate 11 is to enhance the visual effect of the projection panel to achieve a crystal-like projection panel effect. As shown, the transparent substrate 11 has a flat shape and has a first plane 111 and a second plane H2 opposite to the first plane 111 of the M317591. A metal particle layer 12 (not shown in Fig. 4) such as silver powder or aluminum powder is uniformly attached to the first plane 111. The metal particle layer 12 preferably has a light blocking rate of one hundred percent, so that when the image projected by the projector reaches the projection panel 10, 20 or 30, it can be clearly and brightly displayed by the reflection of the metal particle layer 12. come out. t The method of attaching the metal particle layer 12, in Fig. 2, first, metal particles such as silver powder or powder powder are mixed into a cement such as a resin, and the glue mixed with the metal particles is sprayed or printed on the transparent On the substrate 11, the glue φ mixed with the metal particles is sprayed or printed on the plastic film, and then the film is transferred onto the transparent substrate 11. Further, in Fig. 3, a binder mixed with metal particles is sprayed or printed on a plastic film 13 made of, for example, a polycarbonate, a polyvinyl chloride (PVC) or a saturated polyester (ΡΠ). Then, the plastic film 13 to which the metal particle layer 12 is attached is attached to the transparent substrate 11 directly or by applying a backing. In order to improve the durability of the projection panel 10, 20 or 30, it is also possible to mix the metal particles such as silver powder or aluminum powder into a binder such as a resin, while mixing the wear-resistant powder to make the metal particle layer 12 The hardness can reach more than 1H, achieving the effect of scratch resistance and rubbing. In Fig. 4, the first plane 1H of the transparent substrate 11 has a metal particle layer 12 (not shown) which is uniformly adhered, for example, of silver powder or aluminum powder, as shown in Fig. 2 or 3. The second flat surface 112 of the material 11 also has a uniformly attached atomization treatment layer 31. The atomization treatment layer 31 may be a glass bead powder, mica powder, quartz powder or the like which is glued or bonded with a plastic film. a thin layer having a light transmittance of, for example, between 40% and 95%, and a thickness of, for example, between 1 and 4 microns, preferably atomized Layer 31 has a thickness of 2 microns. Therefore, the projection board 30 of FIG. 4 can project the image on the first plane 111 of the transparent substrate 11 in addition to the projection board 1 of FIG. 2 or the M317591 ... projection board 20 of FIG. 3, The image is projected onto the second plane 112 of the transparent substrate 11. Due to the atomization treatment layer 31 attached to the second plane 112 of the transparent substrate 11, the concentrated intense light projected onto the projection plate 30 can be scattered without forming a glare image, and therefore, projected on the transparent bottom according to the measured result. The image on the second plane 112 of the material 11 has a better display effect than the image projected on the first plane 111 of the transparent bottom material 11. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention. Any of the various changes and refinements made by those skilled in the art without departing from the spirit and scope of the present invention are also The scope of creation. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
