Each display device includes a front surface that is viewed by user. Each front surface defines a display area and a border area. Each image compensating element is on the front surface. Each image compensating element includes a light-incident surface on the display area, a light-emitting surface coupling to the light-incident surface, and a connecting surface coupling between the light-incident surface and the light-emitting surface. Each image compensating element includes a plurality of light guiding channels. Light guiding paths of the light guiding channels curvedly extend along a direction from the light-incident surface toward the light-emitting surface. ## Claims ### Claim 1 A display assembly, comprising: at least two display devices arranged side by side, each of the at least two display devices comprising a front surface adapted for displaying image, the front surface defining a display area and a border area outside the display area; and two image compensating elements at a juxtaposition of every adjacent two of the display devices, each of the two image compensating elements being on the front surface of a corresponding one of the adjacent two display devices; each of the image compensating elements comprising a light-incident surface on the display area, a light-emitting surface coupling to the light-incident surface, and a connecting surface coupling between the light-incident surface and the light-emitting surface; wherein each of the image compensating elements comprises a plurality of light guiding channels; light guiding paths of the plurality of light guiding channels are independent from each other and curvedly extend along a direction from the light-incident surface toward the light-emitting surface; optical axis direction of each of the plurality of light guiding channels on the light-emitting surface intersects with the light-emitting surface at an angle in a range of 75 degrees to 105 degrees. ### Claim 2 (depends on 1) The display assembly of claim 1, wherein the optical axis direction of each of the plurality of light guiding channels on the light-emitting surface is perpendicular to the light-emitting surface. ### Claim 3 (depends on 1) The display assembly of claim 1, wherein the light-emitting surfaces of the two image compensating elements at the juxtaposition of the adjacent two display devices are coupled together. ### Claim 4 (depends on 3) The display assembly of claim 3, wherein the two light-emitting surfaces of the two image compensating elements at the juxtaposition of the adjacent two display devices are coupled into one plane. ### Claim 5 (depends on 1) The display assembly of claim 1, wherein each of the image compensating elements defines an acute angle formed by the light-emitting surface intersects with the light-incident surface. ### Claim 6 (depends on 1) The display assembly of claim 1, wherein the connecting surface is a curved surface. ### Claim 7 (depends on 1) The display assembly of claim 1, wherein an area size of the light-incident surface is smaller than an area size of the light-emitting surface. ### Claim 8 (depends on 1) The display assembly of claim 1, wherein each of the plurality of light guiding channels is a light guiding fiber. ### Claim 9 (depends on 1) The display assembly of claim 1, wherein two front surfaces of every adjacent two of the display devices intersects with each other at an angle of less than 180 degrees. ### Claim 10 (depends on 1) The display assembly of claim 1, wherein the at least two display devices are arranged in one plane.
