Patent number: 8405577Abstract: A display method of a plasma display apparatus to which primary color video signals are inputted and which carries out color display by letting phosphors for primary colors emit light is provided. The display method displays the primary color video signals by changing a gray level of an output primary color video signal in accordance with a gray level of an input primary color video signal. When each gray level of the inputted primary color video signals changes from a first value to a second value which is larger than the first value, a gray level of a primary color video signal for a phosphor having the largest influence of luminance saturation properties among the phosphors is increased relative to a gray level of the other primary color video signal.Type: GrantFiled: September 2, 2011Date of Patent: March 26, 2013Assignee: Hitachi, Ltd.Inventors: Ken Kumakura, Hideaki Ohki, Yuichiro Kimura, Yasuji Noguchi, Takayuki Ooe

Patent number: 7903050Abstract: In a conventional image display apparatus, since display load ratios for respective lines are different, voltage drop amounts are also different and a difference in brightness occurs in spite of giving the same inputted luminance signal, so that image quality of display image is degraded. In the case where signals at the same luminance level are inputted and displayed, for a pixel on a display panel, an ON pattern of a subfield in one field is changed when a line load ratio of a line including the pixel is changed. That is, an image display apparatus using a display panel having a plurality of pixels is configured so as to include, for each of the plurality of pixels connected to one driving electrode, a load calculating means that calculates the load ratio and a luminance correcting means that calculates a drop amount in luminance level of an inputted video signal for correction.Type: GrantFiled: December 2, 2005Date of Patent: March 8, 2011Assignee: Fujitsu Hitachi Plasma Display LimitedInventors: Yuichiro Kimura, Shunji Ohta, Yoshinori Miyazaki

Publication number: 20090153442Abstract: According to the invention, by forming at least every two frames having video contents corresponding to each frame of a video signal, for example, a frame rate of movie contents whose frame rate is equal to 24 Hz is converted into 48 Hz. A plurality of subfields (SFs) corresponding to each frame of the conversion signal are divided into first and second division SF groups. Each division SF group is further classified into an upper SF group on the large weight side and a lower SF group on the small weight side. The weights of the upper SF groups are made symmetrical between the first and second division SF groups. The weight of each SF belonging to the lower SF group in the first division SF is set to be larger than that in the second division SF.Type: ApplicationFiled: October 2, 2008Publication date: June 18, 2009Applicant: Hitachi, Ltd.Inventors: Katsunobu KIMURA, Takaaki Nishiseto, Yuichiro Kimura, Kiyoshi Takata, Hideaki Ohki

Publication number: 20090040146Abstract: A disclosed plasma display apparatus and a plasma display panel driving method provide improved luminance while preventing decrease in resolution. In the plasma display apparatus, which is adapted to the display of an interlace signal, the maximum number of sustain pulses associated with the emission of light that can be made in one field is calculated, based on the vertical synchronization signal frequency of the input signal. A display load factor of the input signal in the one field is calculated and, based on the calculated display load factor, a target number of sustain pulses in the one field is determined. Based on a relationship between the target number of sustain pulses and the maximum number of sustain pulses, an emission luminance ratio of a sub-display line to a main-display line in the one field is determined.Type: ApplicationFiled: February 27, 2008Publication date: February 12, 2009Inventors: Masanori TAKEUCHI, Yasunobu Hashimoto, Hideaki Ohki, Yuichiro Kimura, Naoki Itokawa, Yasuji Noguchi

Publication number: 20080278416Abstract: In a PDP apparatus (multiple grayscale display apparatus), an technique for reducing the unevenness of the electric charge states between cells and the background emission by the reset discharge, and also reducing the false outline, therefore, the image quality can be improved, and the drive can be stabilized is provided. In a multiple grayscale display method by sub field method, a structure in which as a sub field lighting pattern, in only specified sub fields (example: SF3, SF9), light-off sub fields in halfway of continuous light-on sub fields are permitted, is employed. Thereby, the unevenness of the electric charge states between cells is reduced and omission of reset discharge becomes easy, since the number of light-off in halfway is small, the false outlines is reduced.Type: ApplicationFiled: June 15, 2007Publication date: November 13, 2008Inventors: Shunji Ohta, Shinsuke Tanaka, Yuichiro Kimura
