  • Publication number: 20220026949
    Abstract: An example support structure for a laptop computer is disclosed. The support structure is extendable and connected to the rear surface of the laptop. The support structure has conduits, a foot assembly, and pairs of magnets. The foot assembly includes a foot section and a connection member. The pair of magnet holds the connection member in a way that the foot remains at a closed or retracted position, and the second pair magnet holds the connection member in a way that the foot remains in an open or extended position. The support structure also has a heat dissipation section under the foot which enhances the heat dissipation property of the laptop when the foot is in the open or extended position.

  • Publication number: 20120104963
    Abstract: A light source apparatus and a light source adjusting module are provided. The light source apparatus includes a power supply, a phase modulator, an electrical transformer, a light source adjusting module and a light-emitting device. The power supply provides a first AC voltage signal. The phase modulator receives the first AC voltage signal and adjusts a conducting phase of the first AC voltage signal to generate a modulated AC voltage signal. The electrical transformer transforms the modulated AC voltage signal to generate a second AC voltage signal. The light adjusting module generates a luminance adjusting signal according to a state of the second AC voltage signal. The light-emitting device receives the luminance adjusting signal to generate a corresponding light source.

  • Publication number: 20100045585
    Abstract: A method for eliminating deficient image on a liquid crystal display (LCD) is provided. The method is used for eliminating the deficient image generated during the shutdown period in a normally white LCD. The method comprises the following steps. First, when a power indication signal changes from a first state to a second state, a black frame is displayed in a first period of time. At the end of the first period, a white frame is displayed in a second period of time. At the end of the second period, the supply of a negative scan voltage is stopped and a white frame is displayed in a third period of time. At the end of the third period, the power is turned off.
