Problems solved by technology

For the current mechanical billboards, for the billboards that need to quickly and completely switch the advertising screen, the billboard of the rotating triangular prism is generally used. Through the rotation of the triangular prism, three kinds of screens can be switched; however, its outstanding The disadvantage is that it is very difficult to make the picture. It is necessary to cut each picture into a large number of vertical strips, and paste each vertical strip on one side of a triangular prism, and the production cost is huge; The triangular prism is transmitted at the same time, and its transmission structure is complex, easy to damage, and difficult to maintain

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0018] like figure 1 As shown, the four-picture billboard includes a frame 1; a picture 2 is laid in the frame; the picture is divided into MN square comprehensive pixel blocks of an M×N array; each of the comprehensive pixel blocks is divided into 2×2 4 square independent pixel blocks of the array; such as figure 2 As shown, two adjacent pixels of an advertisement picture are printed on the independent pixel block at the same position on the adjacent comprehensive pixel blocks 21, 21', 21 "; the independent pixel at the same position block, ie figure 2 Independent pixel blocks with the same serial number in each integrated pixel block; for example, for three adjacent pixels in an advertisement picture, printed on figure 2 The position with the serial number 1, or the position with the serial number 2, or the position with the serial number 3, or the positio...

Abstract

The invention provides a four-screen advertising board. The four-screen advertising board comprises a frame; a screen is laid inside the frame and divided into M*N square comprehensive pixel blocks in M*N arrays; every pixel block is divided into four square independent pixel blocks in 2*2 arrays; the independent pixels blocks in the same positions of the neighboring comprehensive pixel blocks are printed with the neighboring two pixels of one advertising image. The four-screen advertising board also comprises a shade board, the shade board is driven by a stepping motor and can move vertically and horizontally along the screen, and the shade board exposes only one of the independent pixel blocks in the same position of every comprehensive pixel block when in any position. The four-screen advertising board is convenient to manufacture, simple in structure and less prone to damage.
