  • Patent number: 11941637
    Abstract: Disclosed is a method of processing item sales information by an electronic apparatus including acquiring a purchase request including item information related to an item selected by a user and information related to a payment means, providing a purchase response including approval information corresponding to the purchase request before proceeding with payment through the payment means in response to the purchase request when the information related to the payment means satisfies a first condition, transmitting a release request for the item to a first server; and requesting payment for at least some of an amount corresponding to one or more purchase requests related to the payment means according to an arrival of settlement timing corresponding to the payment means.

  • Publication number: 20090244111
    Abstract: A data processor receives sets of input image data having respective input grays and outputs sets of output image data having respective output grays. Each set of output image data corresponds to one of the plurality of sets of input image data and have more image data than each set of the input image data. A data driver supplies the pixels with data voltages corresponding to the output image data supplied from the data processor. A set of output grays corresponding to a set of input grays are selected from sets of grays, each set of grays giving an average front transmittance substantially equal to an average front transmittance of the set of input grays. The sets of output grays generate the closest average lateral gamma curve generated by the sets of grays relative to an average front gamma curve generated by the input grays.

  • Publication number: 20070091043
    Abstract: A liquid crystal display includes an array pixel including a plurality of pixels arranged in a matrix. The plurality of pixels include a set of pixels including a pair of center pixels adjacent to each other, and a pair of first-color pixels and a pair of second-color pixels obliquely facing each other across the center pixels. Each pixel includes a pixel electrode and a thin film transistor. The liquid crystal display further includes a plurality of gate lines extending in a row direction for transmitting a gate signal to the pixels, and a plurality of data lines extending in a column direction for transmitting data signals to the pixels. The pixels are subject to polarity inversion.

  • Publication number: 20070052984
    Abstract: An apparatus of converting three color image signals into four color image signals having a white signal is provided, which includes: a lookup table storing a plurality of white scaling factors and a signal converter selecting a corresponding white scaling factor of the white scaling factors stored in the lookup table based on a white scaling signal from an external, converting the three color image signals into the four color image signals based on the selected white scaling factor. Like this, by converting into the four color image signals using the selected white scaling factor based on the white scaling signal from the external, the white scaling factor may be varied without change of a device in which conversion algorithm is stored, thereby manufacturing cost decreases.

  • Patent number: 7187354
    Abstract: The present invention relates to an organic electroluminescent display and a driving method thereof, which divides one frame into a plurality of subframes. Since the present invention divides one frame into several subframes, and drives an organic EL device with the subframes assigned to the upper bits and with the corrected gray data for representing the detailed grays between the basic grays during the subframes assigned to the lower bits, it is possible to represent sufficient number of grays regardless of the unstable luminescence characteristics of an organic EL device.
