Abstract
A plasma display device is provided which includes: drive circuits which supply, to display electrodes, progressive scan pulses for performing display on display lines of a plasma display panel based on respective display data, or simultaneous scan pulses for performing display based on the same display data with one even-numbered display line and one odd-numbered display line vertically adjacent to each other of the plasma display panel taken as a set, in each sub-frame of a plurality of weighted sub-frames in one frame; a motion detection circuit which detects a motion of an image based on an image signal; and a sub-frame number decision circuit which decides the number of sub-frames in which the simultaneous scan pulses are supplied in the one frame, according to the motion of the image.
Claims17
A plasma display device comprising:
- a plasma display panel in which one display line is composed of a display electrode pair composed of two display electrodes, and the display electrode pairs of even-numbered display lines and the display electrode pairs of odd-numbered display lines are alternately arranged;
- drive circuits which supply, to the display electrodes, progressive scan pulses for performing display on the display lines of said plasma display panel based on respective display data, or simultaneous scan pulses for performing display based on the same display data with one even-numbered display line and one odd-numbered display line vertically adjacent to each other of said plasma display panel taken as a set, in each sub-frame of a plurality of weighted sub-frames in one frame;
- a motion detection circuit which detects a motion of an image based on an image signal;
- and
- a sub-frame number decision circuit which decides the number of sub-frames in which the simultaneous scan pulses are supplied in the one frame, according to the motion of the image,
- wherein said drive circuits supply the progressive scan pulses or the simultaneous scan pulses to the display electrodes in each of the sub-frames according to the number of sub-frames, decided by said sub-frame number decision circuit, in which the simultaneous scan pulses are supplied.
