    Products Description
    The backboard of the laser projection screen is made of aluminum honeycomb panel. Due to the special hexagonal structure of aluminum honeycomb panel is composed of many dense hexagonal cells and these cells are similar to many I shapes, which averagely take the pressure from the panel surface. This property assures the high compression strength and super flatness over a large area.
