As a further aspect of the present invention, the first screen point and the second screen point are both in the equidistant gradual amplification type setting.

As a further aspect of the present invention, the base block is shaped like an equilateral right triangle, and the central line of the base block and the central line of the light guide plate are on the same horizontal line.

As a further proposal of the utility model, an adhesive is arranged between the refraction paper and the base block.

As a further proposal of the utility model, the three surfaces of the extending edge except the light-entering surface are frosted surfaces.

Compared with the prior art, the utility model discloses following beneficial effect has: in the utility model, the traditional mesh points with uniform size are set as mesh points with gradually enlarged equidistance by setting the first mesh point and the second mesh point with gradually enlarged equidistance, and the diameter of the mesh point which is farther away from the light source is larger, so that the larger mesh point has better refraction effect when the light is irradiated, the light guide of the light guide plate is more uniform, and when the advertisement box is used, the advertisement display effect is better, and the practicability is higher;

through setting up base block cooperation refraction paper, shine and receive the refraction of refraction paper to prolong the light of limit edge, even from first astigmatic face and the refraction of second astigmatic face, replace the black photomask of traditional light guide plate with base block cooperation refraction paper, can make light shine by even refraction, compare traditional black photomask and can make light shine more sufficient, the practicality is higher.
