Organic electro luminescense display apparatus and application thereof

Abstract

A technology for reducing the so-called “phosphor burn-in” phenomenon where the variation of luminance arises by reducing display luminance of a certain pixel caused by deterioration in a display apparatus constituted by an organic electro luminescence element is provided. In the display apparatus, when displaying an image acquired by an image acquiring unit, luminance substantially same as average luminance of the acquired image is set to a non-display area where the image is not displayed.

         57 . A display apparatus comprising:
 an acquiring unit which acquires a first image to be displayed;   
       a first setting unit which sets a first area in which the first image is displayed and places image on the first area; and
 a second setting unit which sets, when the first area is smaller than an area which can be displayed, a second image to be displayed on a second area in which the first image is not displayed; 
 wherein said second setting unit sets luminance data of the second image as a luminance value of more than 20% and less than 40% of the maximum luminance. 
 
     
     
         58 . The display apparatus according to  claim 57 , wherein said second setting unit sets luminance data of the second image as a luminance value of more than 30% and less than 35% of the maximum luminance. 
     
     
         59 . The display apparatus according to  claim 57 , wherein the second image is an image in which all pixels have substantially same luminance data. 
     
     
         60 . The display apparatus according to  claim 57 , wherein the second image is covered with the luminance value of more than 20% and less than 40% of the maximum luminance or an image with pattern which is prepared in a memory unit beforehand. 
     
     
         61 . A display method of a display apparatus in which display elements that constitute pixels respectively have different degradation characteristics:
 wherein when displaying an image on a display area narrower than an area which can be displayed, luminance data of a non-display area which does not display the image among the area which can be displayed is set as a luminance value of more than 20% and less than 40% of the maximum luminance.   
     
     
         62 . The display method according to  claim 61 , wherein luminance data of a non-di splay area which does not display the image among the area which can be displayed is set as a luminance value of more than 30% and less than 35% of the maximum luminance. 
     
     
         63 . The display method according to  claim 61 , wherein the image is covered with the luminance value of more than 20% and less than 40% of the maximum luminance or an image with pattern which is prepared in a memory unit beforehand. 
     
     
         64 . A display apparatus comprising:
 an acquiring unit which acquires a first image to be displayed;   
       a first setting unit which sets a first area in which the first image is displayed and places the first image on the first area; and
 a second setting unit which sets, when the first area is smaller than an area which can be displayed, a second image to be displayed on a second area in which the first image is not displayed; 
 wherein said second setting unit sets the second image in a manner where brightness of the first image is substantially same as brightness of the second image.
