Abstract
A plasma display device is provided with a plasma display panel and a luminance controller. The luminance controller lowers a luminance on the plasma display panel when there is no change in an input signal for a predetermined position in the plasma display panel within a predetermined time than a luminance when there is a change in the input signal within the predetermined time.
Claims9
A plasma display device, comprising:
- a plasma display panel;
- and
- a luminance controller which lowers the luminance on said plasma display panel when there is no change in an input signal for a predetermined position in said plasma display panel within a predetermined time below a luminance when there is a change in said input signal within said predetermined time,
- wherein said luminance controller includes:
- a detection circuit which detects whether said input signal changes within said predetermined time;
- and
- a control circuit which switches a luminance on said plasma display panel by selecting one of a plurality of tables, each showing a predetermined relation of load versus luminance, based on a result of detection by said detection circuit.
