Patent number: 7466292Abstract: 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.Type: GrantFiled: November 14, 2005Date of Patent: December 16, 2008Assignee: Fujitsu Hitachi Plasma Display LimitedInventors: Ayahito Kojima, Hiroyuki Wakayama, Hirohito Kuriyama, Akira Yamamoto

Patent number: 6724356Abstract: 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.Type: GrantFiled: March 30, 2000Date of Patent: April 20, 2004Assignee: Fujitsu LimitedInventors: Ayahito Kojima, Hiroyuki Wakayama, Hirohito Kuriyama, Katsuhiro Ishida, Akira Yamamoto

Patent number: 6278421Abstract: 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.Type: GrantFiled: September 8, 1997Date of Patent: August 21, 2001Assignee: Fujitsu LimitedInventors: Katsuhiro Ishida, Hiroyuki Wakayama, Hirohito Kuriyama, Akira Yamamoto, Ayahito Kojima, Masaya Tajima, Kyoji Kariya
