Preferably, the third direction a and the fourth direction b may each form an angle of 45 ° with the first direction x.

Embodiment one:

the sub-pixels 1 may include a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13;
each sub-pixel 1 constitutes a plurality of first rectangular repeating units 01 arrayed along the first direction x and the second direction y, the first rectangular repeating units 01 including diagonal lines 01a and 01b extending along the third direction a and the fourth direction b; generally, the shape of the first rectangular repeating unit 01 approximates a square;
each vertex angle position of each first rectangular repeating unit 01 is provided with a first color sub-pixel 11, and a second color sub-pixel 12 and a third color sub-pixel 13 are sequentially arranged between two adjacent first color sub-pixels 11 in the direction of a diagonal line 01a extending along a third direction a of the first rectangular repeating unit 01.
Specifically, in the first embodiment, the sub-pixel 1 and the line segment of the grid are simultaneously rotated by the same angle, for example, 45 ° with respect to the extending direction of the lead 31, so that the sub-pixel 1 is arranged to be a real pixel arrangement in line with viewing in a small size on the display substrate. The adjacent first color sub-pixels 11, second color sub-pixels 12 and third color sub-pixels 13 constitute a 45 ° directional pint + pint arrangement.
Optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 3 and 5, one grid surrounds one sub-pixel 1, and the first distance L of the grid is greater than the second distance W.
Specifically, according to the arrangement mode of the sub-pixels 1, the grids of the touch electrode 2 also form 45-degree-direction product type + inverse product type arrangement, and the arrangement mode can ensure that grids arranged around each sub-pixel 1 have similar wiring aspect ratios, so that the wiring resistances of the grids are similar, and the sensitivity and reliability of touch control are improved.
Optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 3 and 5, the area of the first color sub-pixel 11 may be larger than the area of the second color sub-pixel 12, and the area of the second color sub-pixel 12 may be larger than the area of the third color sub-pixel 13;
as shown in fig. 3 and 4, the grids surrounding the sub-pixels have the same first distance L;
as shown in fig. 4, the grid surrounding the first color sub-pixel 11 has a second distance W1 that is larger than the second distance W2 that the grid surrounding the second color sub-pixel 12 has, and the grid surrounding the second color sub-pixel 12 has a second distance W2 that is larger than the second distance W3 that the grid surrounding the third color sub-pixel 13 has.
Specifically, the second distance W of the surrounding grid may be adjusted according to the areas of the sub-pixels 1 of different colors, the larger the second distance W of the grid disposed around the sub-pixels having the larger area. The grids surrounding each sub-pixel have the same first distance L, so that L/W <2 in each grid can be ensured, and the wiring resistance of the grid is reduced, so that the touch sensitivity is improved. Also, the first line segment 21 and the second line segment 22 of different grids may be set to have the same width to equalize the wiring resistance.
Optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 5, in the first rectangular repeating unit 01, spacers 4 may be disposed between the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 that are arranged in a delta shape, that is, the spacers 4 are disposed in the middle of the pixel defining layers of the three sub-pixels 1 that are arranged in a delta shape; the spacer 4 is generally disposed on the pixel defining layer, and the spacer 4 serves to prevent the vapor deposition mask plate from contacting the display substrate when vapor deposition of the light-emitting layer in the sub-pixel 1 is performed.
The grids surrounding the first color sub-pixels 11 simultaneously surround the spacers 4, namely one grid simultaneously surrounds the first color sub-pixels 11 and the spacers 4, the line segments of the grids avoid the spacers 4 to perform winding design, and the line segments of the grids and the spacers 4 are not overlapped with each other.
Specifically, for the line segment avoiding the spacer 4 in the grid, a design manner as shown in fig. 6 may be adopted, that is, the line segment is set as a fold line, or other manners may be adopted without limitation.
Embodiment two:
optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 7 and 9, each sub-pixel 1 is generally rectangular, two sides of the rectangle extend along the first direction x, and the other two sides extend along the second direction y; i.e. sub-pixel 1 does not rotate relative to pin 31;
the sub-pixels 1 may include a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13;
each sub-pixel 1 constitutes a plurality of second rectangular repeating units 02 arrayed along the first direction x and the second direction y; generally, the shape of the first rectangular repeating unit 02 approximates a square;
each second rectangular repeating unit 02 includes second color sub-pixels 12 and third color sub-pixels 13 arranged x along the first direction, and first color sub-pixels 11 arranged in the second direction y with the second color sub-pixels 12 and third color sub-pixels 13.
Specifically, the sub-pixels 1 are arranged in pi shape according to the prior art in the second embodiment, so as to ensure that the sub-pixels 1 are arranged in real pixel arrangement which accords with the viewing on the display substrate with a small size.
Alternatively, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 7 and 9, the grids may be divided into a first type of grid M surrounding the second color sub-pixels 12 and the third color sub-pixels 13 in the adjacent two second rectangular repeating units 02 and a second type of grid N surrounding the first color sub-pixels 11 of the adjacent two second rectangular repeating units 02.
Specifically, the second embodiment is a case where one grid surrounds a plurality of sub-pixels 1, in which a first type grid M surrounds four sub-pixels 1 (i.e., two second color sub-pixels 12 and two third color sub-pixels 13 arranged along the first direction x), and a second type grid N surrounds two sub-pixels 1 (i.e., two first color sub-pixels 11 arranged along the first direction x). In this way, the extending directions of the line segments in the first type mesh M and the second type mesh N are adjusted to be rotated by an angle, for example, 45 ° with respect to the extending direction of the leads 31. The arrangement mode can ensure that the first type grids M and the second type grids N which are arranged around the plurality of sub-pixels 1 have similar wiring length-width ratios, so that the wiring resistances of the grids are similar, and the sensitivity and the reliability of touch control are improved.
Optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 8, the first type mesh M may include eight first line segments 21 and eight second line segments 22, and may further include two third line segments 23 extending along the second direction y; the length of the first line segment 21 is equal to the length of the second line segment 22, and the length of the third line segment 23 is smaller than the length of the first line segment 21;
the second class of grids N may comprise six first line segments 21 and six second line segments 22, the first distance L within the second class of grids N being equal to the second distance W.
Specifically, the length of the first line segment 21 in the first type of grid M is equal to the length of the second line segment 22, so that L/W is close to 1:1, and L/W in the second type of grid N is also close to 1:1, that is, the first type of grid M and the second type of grid N have similar aspect ratios of routing lines, so that the routing resistances of the grids are similar, and the sensitivity and reliability of touch control are improved.
Further, assuming that the line widths of the grids are uniform, that is, the line widths of the first line segment 21, the second line segment 22, and the third line segment 23 are uniform, the same metal material is selected and the film thicknesses are uniform, RS of the grids are identical, and according to the formula r=r 0 S is equal to L/W, R is proportional to the length L of the line segment, and the equivalent grid length is L according to the current flowing direction Total (S) . When the subpixels 1 are arranged in pi-shape, L is calculated when the conventional grid design method of the touch electrode is adopted Total 1 And L when the grid design mode shown in FIG. 8 of the present invention is adopted Total 2 。
As shown in fig. 10, l1=l2=1/2×pitch=1/2×78=39 μm for a pi-shaped arrangement in which the pitch of the pixels is 78 μm; then L is Total 1 ＝8*L1+5*L2＝8*39+5*39＝507μm。
As shown in the figure 11 of the drawings, let L3++L3++2 =l1≡2, l3=27.58 μm, l4=1/3×l2, l4=13 μm.
L Total 2 ＝16*L3+2*L4＝16*27.58+2*13＝467.28μm。
L Total 1 ＞L Total 2 Therefore, the grid wiring mode can reduce the resistance.
Optionally, in the touch display substrate provided by the embodiment of the present invention, as shown in fig. 9, a grid width d1 of a grid routing area shared by the first type of grid M and the second type of grid N may be greater than a grid width d2 of other areas.
Specifically, since the first type grid M and the second type grid N are far from the sub-pixel 1 by more than or equal to 10 μm at the junction of the first line segment 21 and the second line segment 22, i.e., at the sharp corner, there may be a space for widening the routing, where increasing the grid width may reduce the routing resistance of the entire grid. The distance d3 from the sub-pixel 1 at the increased rear sharp angle is distributed between 1-10 μm.
Optionally, in the touch display substrate provided in the embodiment of the present invention, the first color sub-pixel 11 may be a blue sub-pixel, the second color sub-pixel 12 may be a green sub-pixel, and the third color sub-pixel 13 may be a red sub-pixel.
