In addition, when the source and drain conductive structures are of the same-layer structure, the electrical connection between the light-emitting unit and the sub-pixel circuit can be realized by adjusting the structure of the source and drain conductive patterns without changing the film layer structure of the first electrode in the light-emitting unit.

In addition, the source drain conductive structure comprises a first source drain conductive structure and a second source drain conductive structure, and the first source drain conductive structure and the second source drain conductive structure are arranged along a direction away from the substrate.

In fig. 9, the first four sub-pixels sp (RGBG) in the x-th row may constitute one pixel.

Note that, in fig. 8 and 9, the red sub-pixel R, the blue sub-pixel B, and the green sub-pixel G are denoted by the light emitting unit e of the sub-pixel, and specifically, the red sub-pixel R, the blue sub-pixel B, and the green sub-pixel G are denoted by the first electrode j1 in the light emitting unit e of the sub-pixel, that is, the position where the sub-pixel is located is denoted by the first electrode j1 in the light emitting unit e in fig. 8 and 9, but the embodiment of the present utility model is not limited thereto.

In an exemplary embodiment, n is 2, and in this structure, the parity of the rows of the driving ends corresponding to the sub-pixel groups including the sub-pixels of the same color in different sub-pixel clusters is the same, that is, the rows of the driving ends electrically connected to the sub-pixel groups including the sub-pixels of the same color in the plurality of sub-pixel clusters are all odd rows or all even rows. For example, referring to fig. 7 and 9, a first sub-pixel group q111 of the 2 sub-pixel groups q11 includes a red sub-pixel R and a blue sub-pixel B, a second sub-pixel group q112 of the 2 sub-pixel groups q11 includes a green sub-pixel G, and the red sub-pixel R and the blue sub-pixel B are electrically connected to a first driving end s11 of the 2 row driving ends s1, and the green sub-pixel G is electrically connected to a second driving end s12 of the 2 row driving ends s 1.

In addition, since in the embodiment of the utility model, one row of sub-pixel circuits is electrically connected with the light emitting unit in one sub-pixel group, and then the red sub-pixel R and the blue sub-pixel B are electrically connected with the first driving end s11 all the time, and under the condition that the driving ends of the driving unit are respectively in one-to-one correspondence with the plurality of rows of sub-pixel circuits in the sub-pixel clusters, in different sub-pixel clusters, the red sub-pixel R and the blue sub-pixel B are electrically connected with the sub-pixel circuits in the same row in the sub-pixel clusters all the time, and the green sub-pixel G is also electrically connected with the sub-pixel circuits in the same row in the sub-pixel clusters all the time.

For example, when the first driving end s11 is electrically connected to the first row of the sub-pixel circuits in the sub-pixel cluster, the second driving end s11 is electrically connected to the second row of the sub-pixel circuits in the sub-pixel cluster, the red sub-pixel R and the blue sub-pixel B are always electrically connected to the first row of the sub-pixel circuits in the sub-pixel cluster, the green sub-pixel G is also always electrically connected to the second row of the sub-pixel circuits in the sub-pixel cluster, the red sub-pixel R and the blue sub-pixel B are always electrically connected to the odd row of the sub-pixel circuits, and the green sub-pixel G is always electrically connected to the even row of the sub-pixel circuits. Similarly, the red and blue sub-pixels R and B may be electrically connected to the even-row sub-pixel circuits at all times, and the green sub-pixel G may be electrically connected to the odd-row sub-pixel circuits at all times. The structure can reduce or avoid the brightness difference problem caused by the compensation time difference of the driving transistor shown in fig. 4.
