Display device

A display device in which a plurality of pixels are arranged in the inside of a display area, and the respective pixels include first electrodes to which signals are independently inputted, a common second electrode to which a signal which becomes the reference with respect to the signals is inputted and a third electrode which controls an electric current which flows between the first electrodes and the second electrode, wherein the display device further comprising:

• means which divides the display area into at least a first area and a second area by electrically separating the common second electrode and obtains first information for specifying average brightness of the first area in response to the electric current from the second electrode in the first area, generates a referential voltage being emphasized peak corresponding to a value of the first information for specifying average brightness, and applies the referential voltage to the second electrode,
• means which obtains second information for specifying average brightness of the second area in response to an electric current from the second electrode in the second area and compares the second information for specifying average brightness and the first information for specifying average brightness,
• means which, based on the comparison, selects the referential voltage being emphasized peak when the value of the second information for specifying average brightness is smaller than the value of the first information for specifying average brightness, and selects an auxiliary referential voltage which is larger than the referential voltage being emphasized peak when the value of the second information for specifying average brightness is larger than the value of the first information for specifying average brightness, and
• means which adds the referential voltage being emphasized peak generated in response to the value of the first information for specifying average brightness to the voltage which is applied to the first electrodes or the third electrode in driving the respective pixels of the first area, and adds either one of the referential voltage being emphasized peak and the auxiliary referential voltage which is selected by the selection to the voltage applied to the first electrodes or the third electrode in driving the respective pixels of the second area.

A display device comprising a display area which is constituted of a plurality of light emitting elements, wherein one cathode electrode faces a plurality of anode electrodes in an opposed manner, the display device further comprising:

• a first display area and a second display area which are constituted of different cathodes;
• and
• means for obtaining information for specifying average brightness of the respective display areas in response to a signal which flows in the cathode electrode;
• wherein
• when the brightness of the first display area has the larger brightness than the second display area, a signal applied to the cathode electrodes of the first display area is controlled so as to lower the brightness of the first display area.
