A display controller is disclosed which, when controlling the luminance of an image to be displayed, by controlling the number of sustain pulses forming each of display signals used for a preset display period, stores in a characteristic information storage section a plurality of different characteristic information each for changing the number of sustain pulses in function of the average brightness level of each of video signals corresponding to the image to be displayed, selects one of the stored characteristic information using a selection section, detects the average brightness level of each of the video signals Sin externally supplied for displaying the image, using an APL detection section, sets the number of sustain pulses to be used to display the image by referring to the selected one of the characteristic information based on the detected average brightness level, and applies the set numbers of sustain pulses to a PDP to display the image.

Display controller and display apparatus

A display device is designed to ensure that image processing parameters are transferred in response to switching between input video signals. The display panel is forceably stopped from being driven for a predetermined period when a video signal of an input target is switched over to another video signal.

Display device

A method of and a system for controlling a brightness of a picture displayed on a plasma display panel are provided which are capable of determining whether a video signal to be fed to the plasma display panel is a signal indicating a stationary picture, reducing the brightness of a picture displayed on the plasma display panel if it is determined that a video signal to be fed to the plasma display panel is a signal indicating a stationary picture.

Method of and system for controlling brightness of plasma display panel

A driving apparatus of a plasma display panel which is capable of reducing the scale of the driver itself while limiting power consumed by the plasma display panel. The value of power consumed during a non-light emitting period in one field (frame) period is added to an average luminance level of an input video signal to derive average power consumption, and the power consumed by the plasma display panel is controlled on the basis of the average power consumption.
