Abstract:
In a plasma display apparatus capable of displaying an image for stereoscopic view, the image display quality is enhanced. For this purpose, the plasma display apparatus includes a driver circuit and a timing generation circuit. The driver circuit drives the plasma display panel in a manner such that a field for the right eye and a field for the left eye are alternately repeated, each field is formed of an all-cell initializing subfield and a selective initializing subfield, and the top subfield of each field is the all-cell initializing subfield. The timing generation circuit generates shutter opening/closing timing signals. The timing generation circuit generates the shutter opening/closing timing signals such that both timing signal for opening/closing the right eye shutter and timing signal for opening/closing the left eye shutter are set to OFF in the all-cell initializing period of the fields for the right eye and for the left eye.
Abstract:
A plasma display apparatus usable as a 3D image display apparatus can reduce the crosstalk for a user who views a 3D image displayed on a plasma display panel through shutter glasses. For this purpose, the plasma display apparatus displays the 3D image on the plasma display panel having a plurality of pixels each of which is formed of a plurality of discharge cells by alternately repeating a right-eye field and a left-eye field. The plasma display apparatus adds a predetermined gradation value to an image signal to be displayed in a certain field when the number of pixels where the gradation equal to or higher than a high gradation threshold is displayed in the field immediately before a certain field and the gradation equal to or lower than a low gradation threshold is displayed in the certain field is equal to or larger than a number-of-pixels threshold.
Abstract:
A drive method for a plasma display panel having a plurality of priming electrodes, wherein the pulse width of a scanning pulse to be applied to a scanning electrodes, out of a plurality of scanning electrodes, for generating a priming discharge and carrying out writing as a result of self scanning is made larger than the pulse width of a scanning pulse to be applied to a scanning electrodes for not generating a priming discharge but carrying out writing as a result of self scanning.
Abstract:
A high-quality stereoscopic image is displayed by suppressing crosstalk between an image for the right eye and an image for the left eye and stabilizing an address discharge. For this purpose, in the method for driving the plasma display apparatus, an image for the right eye and an image for the left eye are alternately displayed on the plasma display panel by alternately repeating a field for the right eye and a field for the left eye. In each of the field for the right eye and the field for the left eye, the subfield having the smallest luminance weight is placed first, the subfield having the largest luminance weight is placed next, and the other subfields are placed thereafter so as to have luminance weights sequentially decreasing.
Abstract:
One field is formed of a plurality of sub-fields, and each one of the sub-fields includes an initializing period, addressing period, and sustained period. The sub-field is one of an entire-cell initialization sub-field or a selective-cell initialization sub-field. When the entire initialization sub-field is switched to the selective one or vice versa, an initializing voltage which generates initializing discharge in the entire initialization sub-field is controlled. This control allows varying the number of the entire initializations and stabilizing address discharge in a plasma display panel, and at the same time, making the black luminance inconspicuous for improving the picture quality.
Abstract:
A method for driving a plasma display panel in which discharge cells are provided at the non-connected intersections of scan electrodes and data electrodes and of the sustain electrodes and data electrodes. One field period is composed of sub-fields each comprising an initializing period, a write period, and a sustain period. The sustain period of at least on sub-field is composed of a first sustain period in which the transition period of the sustain pulse applied to the scan electrode does not temporally overlap with the transition period of the sustain pulse applied to the sustain electrode and a second sustain period in which the transition period of the sustain pulse applied to the scan electrode temporally overlaps with the transition period of the sustain pulse applied to the sustain electrode. The second sustain period includes at least the end part of the sustain period.
Abstract:
A subfield lighting rate measuring unit detects a lighting rate for each subfield, and a subfield processor controls a scan driver and a sustain driver so that a recovery time of each sustain pulse, a resonance time of LC resonance and a sustain period become longer as the detected lighting rate for each subfield becomes smaller.
