Display system and method for managing display

A display system comprising:

• a display;
• and
• a driving voltage-adjusting section for adjusting a driving voltage supplied to said display to compensate decrease in luminance.

A display system comprising:

• a display comprising an optical guide plate for introducing light from a light source thereinto, and a driving section provided opposingly to a first plate surface of said optical guide plate and arranged with actuator elements of a number corresponding to a large number of picture elements, wherein a screen image corresponding to an image signal is displayed on said optical guide plate by controlling a displacement action of said actuator element in a direction to make contact or separation with respect to said optical guide plate in accordance with an attribute of said image signal to be inputted so that leakage light is controlled at a predetermined portion of said optical guide plate, and wherein said actuator element makes said displacement action in a first direction when a voltage of positive polarization or negative polarization with respect to a reference electric potential is applied;
• and
• a switching means for making changeover to said voltage of positive polarization or said voltage of negative polarization at an arbitrary timing.

A method for managing a display wherein:

• said display is constructed by arranging a large number of display components;
• and
• a display area of said display is separated into a moving picture display area and a still picture display area on the basis of address data to indicate said display component supplied from a central facility connected to a network.

A method for managing a display comprising:

• monitoring a power source current of said display;
• and
• transmitting status information obtained by said monitoring to a central facility via a network.

A method for managing a display comprising adjusting a driving voltage supplied to said display to compensate decrease in luminance on the basis of collective centralized control by a central facility connected to a network or by schedule management by the aid of a timer.

A method for managing a display comprising rewriting luminance correction data in order to correct a luminance distribution of said display on the basis of collective centralized control by a central facility connected to a network or by schedule management by the aid of a timer.

A method for managing a display comprising:

• using a display comprising an optical guide plate for introducing light from a light source thereinto, and a driving section provided opposingly to a first plate surface of said optical guide plate and arranged with actuator elements of a number corresponding to a large number of picture elements, wherein a screen image corresponding to an image signal is displayed on said optical guide plate by controlling a displacement action of said actuator element in a direction to make contact or separation with respect to said optical guide plate in accordance with an attribute of said image signal to be inputted so that leakage light is controlled at a predetermined portion of said optical guide plate, and wherein said actuator element makes said displacement action in a first direction when a voltage of positive polarization or negative polarization with respect to a reference electric potential is applied;
• and
• making changeover to said voltage of positive polarization or said voltage of negative polarization at an arbitrary timing on the basis of collective centralized control by a central facility connected to a network or by schedule management by the aid of a timer.
