  • Power management device and display device including the same
    Patent number: 11676520
    Abstract: The present disclosure relates to a technology for a power management device applied to a display device, in which driving voltages having different levels are supplied to driving devices having different sizes of load in different times, and this allows all of the driving devices to stably receive voltages within a limited range even though the number of driving devices increases according to the enlargement of a display panel.
    Type: Grant
    Filed: August 20, 2021

  • LIGHTING APPARATUS
    Publication number: 20170202072
    Abstract: Disclosed is a lighting apparatus using an LED as a light source. The lighting apparatus may include: a first driver configured to control a flow of a first current through a low-power switching element by comparing a reference voltage and a sensing voltage, in response to light emission of an LED group; and a second driver configured to form a flow of a second current through a high-power switching element in connection with the flow of the first current of the first driver, in response to light emission of the LED group. The lighting apparatus stably provides a current path for a current corresponding to high power.
