Description of the Invention (1) [Field of the Invention] The present invention relates to a method for manufacturing a Fresnel lens, in particular, a method for manufacturing a Fresnel lens using a local glue method to apply light-solidifying glue. [Knowledge The higher the quality, the higher the quality of the display. The Fresnel light is within the angle, the Fresnel chart is hot-pressed, and a large size of Fresnel is acrylized. The technology of HDTV and DVD Player Pulai has been valued by the market. Under consideration of price, it is one of the development directions. Generally speaking, the rear projection screen is the screen that enters the viewer's eyes, and it is thin and light. Therefore, the main function of increasing the contrast of the image and solving the lens is to gather the light to make the original divergent to increase the brightness of the image. The structure of the eye lens is mainly composed of case resin. Its manufacturing method is' but the product size is generally continuous. The products with limited production processes can only be batch-molded. Ester, polypropylene resin or scale mold method is used in the acrylic large-screen and large-sized display image large-sized display. As the projection television is made into the image projection of the projector in the optoelectronic industry, it is worn on the market. The large size and high design need to take into account the image variation of the viewing angle. Among them, the light emitted by the projector with a large divergence angle can be focused on the viewer's view. An acrylic sheet and a phenanthrene method have injection molding, casting molds, and small products that are limited by production equipment to less than 20 inches, and casting is produced. The conventional polyurethane and polyfluorene are copolymers that are hardened into a Fresnel lens pattern at room temperature.
