• 3). Carve out concave lines or print convex lines and strike out concave spots or print convex spots on the back of the first transparent acryl board, and then adhere a first reflective membrane to the back of the first transparent acryl board. Carve out at least one first stencil area according to the position and shape of the picture or text area on the surface layer, and then install the first LED light source along the edge of one side of the first transparent acryl board to form the first light guide board;
• 4). Select acryl board material to make at least one second transparent acryl board according to the picture or text area on the surface layer as need by the advertising screen. The shape of this second transparent acryl board also matches the shape of the first stencil area. Carve out concave lines or print convex lines and hit concave spots or print convex spots on the back of the second transparent acryl board, and then adhere a second reflective membrane to the back of the second transparent acryl board. Finally install the second LED light source along the edge of the second transparent acryl board to make the second light guide board;
• 5). Adhere the advertising picture film to the front surface of the first light guide board, and then adhere the front surface of at least one second light guide board to the first stencil area on the back of the first light guide board. During adhering, the positions and shapes of the stencil area on the first reflective membrane and of the second light guide board should correspond and match the position and shape of the picture or text area on the advertising screen to form the entire light-emitting advertising board;
• 6). Fabricate the program controller, and compile the driving program according to the light-emitting and flashing requirements or the position and shape of the picture or text area on the advertising screen and according to the light-emitting sequence of the first light guide board and several second light guide boards. Then write the compiled driving program into the control module of the program controller;
