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 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： The plasma display device has a plasma display panel and a driving part for driving the plasma display panel in a subframe mode. The driving part has a circuit for calculating the length of one frame based on one period of a vertical synchronizing signal introduced along with an image signal from an external device, a circuit for calculating the total number of sustaining pulses contained in one frame based on a brightness information contained in the image signal, and a circuit for calculating the length of one driving period required for displaying one frame. The length of one frame and the length of one driving period thus obtained are then compared in a comparing circuit. If the one frame length is found to be shorter than the one driving length, the total number of sustaining pulses or the number of scan lines will be reduced so that the one frame length becomes shorter than the length of one driving period, thus avoiding an extraordinary display.

摘要： An intraframe time-division multiplexing type display device prevents prominent image defects, such as flicker, and affords a high-quality image display. A single frame of an image is displayed while changing a gray-scale level thereof by means of a number of sub-frames, each sub-frame comprising at least an address period and a sustained discharge period; further, the sub-frames have respective, mutually different sustained discharge periods. A gray-scale level adjustment unit arbitrarily sets the selection sequence of each of the number of sub-frames within an individual frame that is to be in a sustained discharge state.

摘要： According to the present invention, a plasma display apparatus, which represents the luminance of one frame in accordance with a combination of plural sub-frames having luminance levels corresponding to a plurality of weighted values, additionally includes a sub-frame having a luminance level lower than the minimum gray scale level of luminance which can be represented by the number of bits in the input video data. Such plasma display apparatus turns on a desired combination of the sub-frames so as to increase the resolution of the luminance without increasing the conventional number of gray scale levels included in the input video data. In a preferred embodiment, especially when the added smaller luminance sub-frame is included in a combination of sub-frames for a low luminance area, the resolution of the gray scale of the low luminance area can be increased, and the representation of gray scale can be enhanced in a low luminance area to which the sight of a person is more sensitive.

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.
