Referring to Claim 1, Tang teaches in Fig. 5-7 for example, a display substrate, comprising: a base substrate; a plurality of pixels, located on the base substrate; each pixel comprising a plurality of sub-pixels (1-3); the plurality of sub-pixels (1-3; par. 64) comprising a first color sub-pixel (1; blue), a second color sub-pixel (2; green), and a third color sub-pixel (3; red), wherein a light-emitting region of one pixel is located in one dummy pattern, light-emitting regions of different pixels are located in different dummy patterns, adjacent dummy patterns where light-emitting regions of adjacent pixels are located do not overlap with each other, the dummy pattern comprises a circle (par. 64); and in each pixel among the at least one pixel, a light-emitting region of the second color sub-pixel (2) surrounds at least a portion of a light-emitting region of the first color sub-pixel (1). Referring to Claim 3, Tang further teaches the display substrate, wherein at least one dummy pattern comprises a first region (whole area inclusive of 3) and a second region (partial area inclusive of 1 and 2), a light-emitting region of the third color sub-pixel (3) is located in the first region, at least a portion of the light-emitting region of the second color sub-pixel (2) and the light-emitting region of the first color sub-pixel (1) are located in the second region, and the light-emitting region of the second color sub-pixel (2) surrounds an edge of the light-emitting region of the first color sub-pixel (1) away from the light-emitting region of the third color sub-pixel (3). Referring to Claim 14, Tang further teaches wherein the plurality of dummy patterns corresponding to the plurality of pixels each comprise the first region (inclusive of 3) and the second region (inclusive of 1 and 2), and directions pointing from centers of the first regions (inclusive of 3) to centers of the second regions (inclusive of 1 and 2) all are the same. Referring to Claim 17, Tang further teaches wherein the plurality of dummy patterns comprises a plurality of dummy pattern rows; the plurality of dummy pattern rows comprises a plurality of first dummy pattern rows located in odd-numbered rows and a plurality of second dummy pattern rows located in even-numbered rows; dummy patterns in the plurality of first dummy pattern rows are arranged in an array along a row direction and a column direction, dummy patterns in the plurality of second dummy pattern rows are arranged in an array along the row direction and the column direction; and a first dummy pattern row and a second dummy pattern row adjacent to each other are shifted in the row direction (see Fig. 5). Referring to Claim 6, Tang further teaches wherein, in each pixel among the at least one pixel, the counts of first color sub-pixels (1) and third color sub-pixels (3) are both one, and the count of second color sub-pixels (2) is at least one. Referring to Claim 7, Tang further teaches wherein the first color sub-pixel (1) comprises a first light-emitting region, the second color sub-pixel (2) comprises a second light-emitting region, and the third color sub-pixel (3) comprises a third light-emitting region; in each pixel among the at least one pixel, an area of the first light-emitting region (of 1) and an area of the third light-emitting region (of 3) are both larger than an area of the second light-emitting region (of 2), and a distance between edges of the second light-emitting region (of 2) and the first light-emitting region (of 1) that are close to each other is less than a distance between edges of the first light-emitting region (of 1) and the third light-emitting region (of 3) that are close to each other. Referring to Claim 22, Tang further teaches a display device, comprising the display substrate according to claim 1 . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 2, 4, 5, 8-12, 15, 16, 18, 19 and 20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. 13-03-01 AIA The following is a statement of reasons for the indication of allowable subject matter: Regarding Claim 2, the prior art of record alone or in combination neither teaches nor makes obvious the invention of the display substrate, wherein a center of the circle or the ellipse is located between the light-emitting region of the first color sub-pixel and a light-emitting region of the third color sub-pixel; or, a center of the circle or the ellipse is located on an edge of the light-emitting region of the first color sub-pixel, and the edge is an edge close to a light-emitting region of the third color sub-pixel; or, a center of the circle or the ellipse is located on an edge of a light-emitting region of the third color sub-pixel, and the edge is an edge close to the light-emitting region of the first color sub-pixel in combination with all of the limitations of Claims 1 and 2. Regarding Claim 4, the prior art of record alone or in combination neither teaches nor makes obvious the invention of the display substrate wherein, in each pixel among the at least one pixel, edges of the light-emitting region of the first color sub-pixel and a light-emitting region of the third color sub-pixel that are close to each other are both straight edges, at least one of edges of the light-emitting region of the first color sub-pixel and the light-emitting region of the third color sub-pixel that are away from each other comprises a fold edge or a curved edge, and the fold edge or the curved edge is bent towards the straight edges in combination with all of the limitations of Claim 1 and 4. Claim 5 includes the limitations of claim 4. Regarding Claim 8, the prior art of record alone or in combination neither teaches nor makes obvious the invention of the display substrate wherein an area of the first region is equal to an area of the second region in combination with all of the limitations of Claim 1, 3 and 8.
