Abstract

A display device includes pixels having different arrangements of subpixels and reducing a color edge. The display device includes a display unit where a plurality of first pixels including subpixels of three colors and second pixels including subpixels of the three colors are alternately arrayed in row and column directions, an arrangement of the subpixels in the first pixel and an arrangement of the subpixels in the second pixel differing from each other, and a luminance allocation unit allocating luminance of a subpixel of a first color among the three colors in the first pixel to a subpixel of the first color in the second pixel adjacent to the first pixel with a predetermined ratio and allocating luminance of the subpixel of the first color in the second pixel to the subpixel of the first color in the first pixel adjacent to the second pixel with a predetermined ratio.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A display device comprising:
 a display unit where a plurality of first pixels including subpixels of three colors and a plurality of second pixels including subpixels of the three colors are alternately arrayed in row and column directions, an arrangement of the subpixels in the first pixel and an arrangement of the subpixels in the second pixel being different from each other; and   a luminance allocation unit configured to allocate luminance of a subpixel of a first color among the three colors in the first pixel to a subpixel of the first color in the second pixel adjacent to the first pixel with a predetermined ratio and allocates luminance of the subpixel of the first color in the second pixel to the subpixel of the first color in the first pixel adjacent to the second pixel with a predetermined ratio.   
     
     
         2 . The display device according to  claim 1 ,
 wherein a subpixel of a second color and a subpixel of a third color among the three colors in the first pixel are arranged along a first side of the first pixel, and the subpixel of the first color in the first pixel is arranged along a second side of the first pixel, the second side facing the first side,   wherein a subpixel of the second color and a subpixel of the third color among the three colors in the second pixel are arranged along a first side of the second pixel, and the subpixel of the first color in the second pixel is arranged along a second side of the second pixel, the second side facing the first side, and   wherein the luminance allocation unit allocates luminance of the subpixel of the first color in the first pixel to the subpixel of the first color in the second pixel adjacent to the first pixel in an arrangement direction of the pixels and the subpixel of the first color in a different first pixel close to the first pixel in a diagonal direction.   
     
     
         3 . The display device according to  claim 2 , wherein the luminance allocation unit allocates all of the luminance of the subpixel of the first color of the first pixel to the second pixel and the different first pixel. 
     
     
         4 . The display device according to  claim 2 , wherein the luminance allocation unit do not allocate the luminance of the subpixel of the first color in the first pixel to the different first pixel. 
     
     
         5 . The display device according to  claim 1 , wherein the luminance allocation unit further allocates luminance of a subpixel of a second color among the three colors in the first pixel to a subpixel of the second color in the second pixel adjacent to the first pixel with a predetermined ratio. 
     
     
         6 . The display device according to  claim 5 , wherein the luminance allocation unit further allocates luminance of a subpixel of a third color among the three colors in the first pixel to a subpixel of the third color in the second pixel adjacent to the first pixel with a predetermined ratio. 
     
     
         7 . The display device according to  claim 2 ,
 wherein, in the first pixels and the second pixels, an arrangement direction of the subpixels of the second color is parallel to an arrangement direction of the subpixels of the third color,   wherein the subpixel of the first color in the first pixel is located on a side of the second color in an arrangement direction of the subpixels of the second color and the subpixels of the third color, and   wherein the subpixel of the first color in the second pixel is located on a side of the third color in an arrangement direction of the subpixels of the second color and the subpixels of the third color.   
     
     
         8 . The display device according to of  claim 1 , wherein the luminance allocation unit allocate luminance of the subpixel in the first pixel in a case where the first pixel is located at an odd point of an image. 
     
     
         9 . The display device according to  claim 1 ,
 wherein a sum of the first pixels and the second pixels is equal to the number of pixels included in the image signal input to the display device.   
     
     
         10 . The display device according to  claim 1 ,
 wherein each of the subpixels comprises a pixel circuit, an organic light emitting element which includes an anode electrode, a cathode electrode and an organic light emitting layer disposed between the anode electrode and the cathode electrode,   wherein the pixel circuit applies a voltage equal to or less than a voltage of the cathode electrode to the anode electrode before the organic light emitting element emits light.   
     
     
         11 . The display device according to  claim 10 , wherein the pixel circuit comprises:
 a driving transistor that controls a current flowing to the organic light emitting element; and
 a switch that controls electrical connection between the driving transistor and the organic light emitting element. 
   
     
     
         12 . A computer readable media including program instructions which when executed by a processor cause the processor to perform the following:
 acquiring an image signal which is to be output to a display unit where a plurality of first pixels including subpixels of three colors and a plurality of second pixels including subpixels of the three colors in an arrangement different from the arrangement of the first pixels are alternately arrayed in row and column directions; and   allocating luminance indicated by the image signal with respect to a subpixel of a first color among the three colors in the first pixel to a subpixel of the first color in the second pixel adjacent to the first pixel with a predetermined ratio and allocating luminance indicated by the image signal with respect to the pixel of the first color in the second pixel to the subpixel of the first color in the first pixel adjacent to the second pixel with a predetermined ratio.
