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 method of displaying a picture at a predefined position on a color organic EL display, the method comprising increasing or decreasing the number of parts thereof being lighted according to a situation, wherein
 all parts constituting the picture are lighted when the situation is at best,   the number of parts being lighted is decreased as the situation grows worse, and   the higher the probability of lighting of a part, the lower the luminance of the part set beforehand.   
     
     
         58 . The method of displaying a picture according to  claim 57 , wherein
 the display is a unit for receiving electric waves,   the situation is an intensity of received electric waves, and   the picture is an antenna picture showing the intensity of electric waves that a communication unit should receive.   
     
     
         59 . The method of displaying a picture according to  claim 57 , wherein
 the display is a battery-driven unit,   the situation is residual quantity of a battery, and   the picture is a battery residual quantity picture showing the residual quantity of the battery driving the unit.   
     
     
         60 . The method of displaying a picture according to  claim 57 , wherein
 the picture is an antenna picture including a plurality of bars or a battery residual quantity picture including a plurality of bars, and   the luminance of a bar more likely to be lighted is set to be lower than the luminance of a bar less likely to be lighted.   
     
     
         61 . The method of displaying a picture according to  claim 60 , wherein
 all of the plurality of bars differ in length, and   a longer bar is designed to be displayed with less probability and with higher luminance than a shorter bar.   
     
     
         62 . The method of displaying a picture according to  claim 57 , wherein different parts of a picture are displayed with different luminance levels, and parts constituting a character are displayed with identical luminance regardless of the probability of display. 
     
     
         63 . The method of displaying a picture according to  claim 57 , wherein a position of the picture is fixed, and a position of a character is movable. 
     
     
         64 . A method of displaying a plurality of pictures on a color organic EL display, wherein
 the picture is a symbol switched and displayed according to a situation of a device in which the display is installed such that the higher the probability of a picture being displayed, the lower the luminance of the picture set beforehand, and symbols showing the same situation are displayed with the same luminance, and   the plurality of pictures is at least one of a picture showing a state during a telephone call, a battery residual quantity picture, a picture showing a state where a key is locked, a picture showing that a manner mode is entered, a picture showing a reception of a mail, a picture showing that a Web search is being conducted, an antenna picture, and a picture showing that a character input mode is entered.   
     
     
         65 . A self-luminous display unit having self-luminous elements, wherein
 the display unit is configured to display, at a predefined position on the display unit, a picture constituted of a plurality of parts and showing a situation of the display unit according to increase or decrease in the number of parts lighted,   all parts constituting the picture are lighted when the situation is at best, and the number of parts being lighted is decreased as the situation grows worse, and   the higher the probability of lighting of a part, the lower the luminance of the part set beforehand.   
     
     
         66 . The display unit according to  claim 65 , wherein
 the display unit is a unit for receiving electric waves,   the situation is an intensity of received electric waves, and   the picture is an antenna picture showing the intensity of electric waves that a communication unit should receive.   
     
     
         67 . The display unit according to  claim 65 , wherein
 the display unit is a battery-driven unit,   the situation is residual quantity of a battery, and   the picture is a battery residual quantity picture showing the residual quantity of the battery driving the unit.   
     
     
         68 . The display unit according to  claim 65 , wherein
 the picture is an antenna picture including a plurality of bars or a battery residual quantity picture including a plurality of bars, and   the luminance of a bar more likely to be lighted is set to be lower than the luminance of a bar less likely to be lighted.   
     
     
         69 . The display unit according to  claim 68 , wherein
 all of the plurality of bars differ in length, and   a longer bar is designed to be displayed with less probability and with higher luminance than a shorter bar.   
     
     
         70 . The display unit according to  claim 65 , wherein different parts of a picture are displayed with different luminance levels, and parts constituting a character are displayed with identical luminance regardless of the probability of display. 
     
     
         71 . The display unit according to  claim 65 , wherein a position of the picture is fixed, and a position of a character is movable.
