Abstract: A display apparatus, that can prevent thermal destruction and burning with a simple structure, has been disclosed. In the apparatus it is judged that there is possibility of a pattern, whose area with high brightness is small, being displayed frequently, when a state in which the total light emission pulse number remains large occurs with high frequency, and if such a state is detected, the total light emission pulse number (sustain frequency) is reduced to prevent the thermal destruction and burning.

Abstract: Provided is a technique of a PDP device capable of preventing error display arising from changes in discharge characteristics in a reset period particularly due to a long-period operation. In the PDP device, a slope of a slope waveform in the reset period is changed corresponding to operation time of the PDP device. And, the slope waveform is made to have a configuration having a stepwise plurality of slopes in a predetermined reset period. For example, when the operation time becomes long, rising and falling slope waveforms of a reset waveform are configured by two steps, and a first slope thereof is made steeper than a slope before the change, and a second slope is made gentle than the slope before the change. When the operation become longer, the first slope is made further steeper and the subsequent second slope is made further gentler.

Abstract: This invention is directed to a technique capable of achieving image quality improvement by the control of reset thinning drive (second drive) in a PDP drive control and of restricting or reducing the generation of hunting in ON/OFF control of the second drive and flickering of background luminance particularly in the case of low-luminance display. In this PDP apparatus, in addition to the control of the second drive using the SF load ratio, the APL value (k) and APL variation value (q) of the field are used, and when the APL variation value (q) is less than a predetermined threshold value, even when the SF load ratio is changed from zero to a value other than zero between SFs, the execution of the first drive is not started, and the execution of the second drive is continued.

Abstract: 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.

Abstract: White noise images and white noise-like pattern images are discerned by making use of the fact that the address current is increased when such an image is entered and detecting the address current by an address current detection circuit. When the detected address current exceeds a given value ? and persists for a given period of time, a CPU controls a contrast control circuit to lower the contrast of the video signal, thus reducing the power consumption of an address driver circuit.

Abstract: 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.
