Abstract:
1. A plasma display device comprising: a display panel for displaying an image according to a driving signal converted from an external image signal; a logic controller for measuring a temperature of the display panel for comparison with a temperature section information having at least two temperature sections, generating a driving control signal for changing the driving signal after the temperature of the display panel changes to a temperature of a different temperature section, and calculating a changing condition included in the driving control signal for determining a changing time of the driving signal; and a driver for supplying the driving signal that is changed according to the temperature section at the changing time determined by the changing condition of the driving control signal, wherein the changing time is a time after the temperature of the display panel changes to a temperature of a different temperature section, and is the time when one of an optical axis calculated by an optical histogram analysis for the image signal is within a reference range of the optical axis, and the time when an amount of light emitted according to the image signal is below a reference amount of light.
