摘要： The method of driving a display apparatus, in which the gradation scale is represented, by the subfield method, with less flicker even when driven at a frequency of 50 Hz has been disclosed. In this method, the two most weighted subfields (subfields of Bn brightness and Bn−1 brightness when it is assumed that the frame is composed of n subfields and the brightness of n subfields is Bi (i =1−n; B1≦B2 . . . Bn−1≦Bn)) are arranged at the interval of about half the length of the frame. Because of this, there exist two peaks of the light emission intensity in a frame, the interval being about half the length of the frame, and if the display apparatus is driven at a frequency of 50 Hz and the length of the frame is 20 ms, the variation period of the light emission intensity is 10 ms and the light emission intensity varies at 100 Hz, therefore, flicker is not detected.

摘要： In a PDP unit, a display frame for one screen comprises a plurality of sub-frames, the luminance of each of which is determined by a sustaining pulse number. A length of one frame is calculated from the length of one cycle of a vertical synchronization signal and a sub-frame condition determination circuit determines, from the length of one frame, the number of sub-frames, the luminance of each sub-frame and a total sustaining pulse number. A load factor is calculated from an external input signal. A further circuit determines a maximum display luminance from consumed power and calculates a luminance factor, and yet a further circuit corrects the luminance drop due to a load from the total sustaining pulse number, the luminance ratio and the load factor for the respective sub-frame and calculates sustaining pulse numbers for the respective sub-frames. Thereby, the sustaining pulse numbers of the respective sub-frames are determined through calculations using the total sustaining pulse number, the luminance ratio, the load factor and the consumed power rather than using a luminance table, simplifying construction of the PDP unit while performing more accurate calculations and thereby improving display quality and providing a stable display without flickering.

摘要： In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation “MCBCMAX−PSUM×MCBCMAX/PSUM,MAX” is set as the MCBC.

摘要： In the PDP device, for example, two types of SF lighting patterns (A and B modes) are equally divided and arranged in spatially different regions in a field. For example, the patterns are arranged in a zigzag manner in units of pixels. At all lighting steps, existence of an absence of light-on SF which becomes a cause of false contour is permitted only in one mode. Accordingly, a generation rate of absence of light-on SF per field when the modes are combined is low, and the level of false contour can be reduced. Further, the spatial arrangement of each mode is optionally changed among the fields.

摘要： The present invention relates to a display device including an interface device, which can prevent from reducing a resolving power of gray scales for a dark picture signal is provided. The interface device according to the present invention is provided to prevent from decreasing a resolving power of luminance gray scales by setting a dynamic range of an analog digital converter according to a peak value of an analog picture signal. Further, a luminance control signal for determining a luminous level of the picture to be displayed is set according to the peak value of the analog picture signal. As the result, the interface device according to the present invention can generate a display signal displaying a picture having a sufficient resolving power of gray scales with a luminance (brightness) required for the darkness, even if a dark picture, of which analog picture signal is comparatively small, is generated.
