  • Publication number: 20230170378
    Abstract: A display device is provided. The display device includes a substrate, a first optical unit, a first light-emitting unit, a second optical unit, a second light-emitting unit, and a light-blocking unit. The first optical unit is disposed on the substrate and includes a first coating layer and a first light guide layer. A light-emitting region of the first light-emitting unit corresponds in position to a first light incident surface of the first light guide layer. The second optical unit is disposed on the first optical unit and includes a second coating layer and a second light guide layer. A light-emitting region of the second light-emitting unit corresponds in position to a second light incident surface of the second light guide layer. The light-blocking unit separates the first light incident surface and the second light incident surface.

  • Patent number: 8405317
    Abstract: The present invention primarily relates to a method for initiating and controlling a lighting equipment by detecting and determining through an algorithm whether a flicker of light may occur during the period of initiating or dimming the lighting equipment. The method further calculates to obtain a current compensation ratio that the current level need be elevated to prevent the occurrence of flicker and performs a real-time compensation for the electrical current, when necessary. The method according to the invention will initiate the lighting equipment at an electrical current level used during a previous stable operation of the lighting equipment, so as to further prevent the occurrence of flicker of light during the initiation of the lighting equipment and achieve the energy saving purpose.
