Embodiment Construction

[0011] A physical gain black rear-projection hard screen, which evenly spreads a layer of medical Vaseline (2) on a transparent acrylic board (1), spreads light black transparent brown paper (3) on the medical Vaseline (2), and then Apply a layer of medical Vaseline (2) on the light black transparent brown paper (3), and finally stick the gray rear projection screen (4) on the medical Vaseline (2). When laying the back light black transparent brown paper (3) and the gray projection screen (4), the air bubbles generated in the middle should be scraped out with a scraper. Otherwise, bubbles will be generated when the projector projects the picture and affect the integrity of the picture. Finally use the metal frame (4) to connect the whole picture frame and then fix the screw bolt (5).
