  • Light guide plate and display device
    Patent number: 9977172
    Abstract: 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.
