  • Publication number: 20140333516
    Abstract: A display device and a driving method thereof are disclosed. In one aspect, the display device includes: a memory which receives an input image data at a first frame frequency and a frame rate controlling unit which converts the input image data to an output image data output at a second frame frequency higher than the first frame frequency by duplicating the input image data to a plurality of frames. The display device also includes a release frame inserting unit which periodically designates release frames in the output image data for resolving a DC bias of one or more continuous frames and a data compensating unit which compensates for a value of the output image data or determines the value of the output image data.

  • Patent number: 8511708
    Abstract: A passenger airbag module includes a housing, an inflator generating gas pressure according to a control signal of an electronic control unit, and an airbag cushion folded in the housing such that the airbag cushion is expanded in the form of a dual chamber. The airbag cushion is provided therein with a tether having a rectangular shape corresponding to a sectional shape of the airbag cushion. The tether is installed in the transverse direction to divide the airbag cushion into an upper chamber and a lower chamber. Transfer holes are formed at edges of the tether. In the passenger airbag module, the upper chamber is primarily expanded by concentrating gas flow into the upper chamber to instantly deploy the airbag cushion in the proper position, thereby safely protecting the occupants.
