  • Patent number: 11740400
    Abstract: A light guide plate has a top side and a bottom side that are opposite to each other, and has a light-incident surface, a light-emitting surface, multiple light guide structures, and an inclined surface structure. The light-incident surface is located at an end of the light guide plate. The light-emitting surface is located on the top side of the light guide plate and is connected to the light-incident surface. The light guide structures are disposed on the light-emitting surface, and each one of the light guide structures has a light-facing surface and an opposite light-facing surface connected to a side of the light-facing surface away from the light-incident surface. The inclined surface structure is connected to the light-incident surface and the bottom side of the light guide plate. A front light module having the light guide plate and a display device having the front light module are also provided.

  • Patent number: 10685596
    Abstract: The present disclosure provides a display apparatus and an operating method thereof. The display apparatus includes a control unit and a display module. The control unit outputs a first signal. The display module is coupled to the control unit, and the display module continuously displays a first image in a first period based on the first signal, in which the first image has a first pattern, and a first ratio of an area of the first pattern to an area of the first image ranges from 5% to 30%. The first pattern has a first brightness at a first time point in the first period, and the first pattern has a second brightness at a second time point in the first period. The second time point is later than the first time point, and the second brightness is less than the first brightness.

  • Patent number: 10657924
    Abstract: The present disclosure provides a display apparatus and an operating method thereof. The display apparatus includes a control unit outputting a first signal and a display module coupled to the control unit. The display module continuously displays a first image in a first frame time based on the first signal, the first image has a first pattern, and a first ratio of an area of the first pattern to an area of the first image ranges from 5% to 30%. The first pattern at a first time point in the first frame time has a color located at a first coordinate position in a CIE 1931 chromaticity diagram, the first pattern at a second time point in the first frame time has another color located at a second coordinate position in the CIE 1931 chromaticity diagram, and the first coordinate position is different from the second coordinate position.
