摘要： 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. In addition, without usage of a white scaling factor fixed into a value, the three color image signals are converted into the four color image signals by using a white scaling factor suitable for characteristics of an LCD, thereby the operation accuracy of the LCD is improved.

摘要： 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.

摘要： 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.
