The embodiments of the disclosure provide a light guide plate, a backlight module, a display device, a dotting machine and a control method thereof, related to the field of display technology, which can improve the brightness uniformity of the backlight module. The light guide plate includes a light exit surface, a bottom surface opposite to the light exit surface, and a light entrance surface intersecting with the light exit surface and the bottom surface. A plurality of dots are arranged at an outer side of the bottom surface; a shape of a cross section of each dot is an ellipse or a polygon, and the cross section is parallel to the bottom surface.

Light guide plate, backlight module, display device, dotting machine and control method thereof

A light guide plate (LGP) and a display device are disclosed. The LGP comprises at least one mesh point; each mesh point is provided with a plurality of microstructures; and all the microstructures on each mesh point are arranged on the same curved surface. The LGP can solve the problem that incident light is subjected to total reflection in the LGP so that the luminous uniformity of the LGP can be improved.
