Background

In the manufacturing process of the AMOLED display, due to the manufacturing process, although the overlapped portions of the metal lines in the pixels are isolated by the insulating layer, the overlapped portions of the metal lines in the array substrate have a risk of short circuit, such as the data signal lines 11 and the scanning signal lines 12; in order to ensure the yield of the panel, a reserved repair line 13 needs to be designed during pixel design, the reserved repair line 13 is electrically connected with the scanning signal line 12 through an electric connecting line 14, and when a lead is short-circuited, a short-circuit point can be repaired through laser cutting, namely, the short-circuited lead is cut off. To ensure that the panel still works properly after cutting, as shown in fig. 1, it is common to use a double-crossover mode for the electrical connection line 14 at the place where the wires are overlapped.

However, the dual-span structure occupies a large space and is difficult to be implemented in a display panel with high pixel density.

The invention aims at the technical problems that the existing array substrate adopts a double-span structure, so that a large amount of space is occupied, and the realization in a display panel with high pixel density is difficult. The present invention can solve the above problems.

An array substrate, as shown in fig. 2, includes a substrate 20, and a plurality of row pixel groups 30 and a plurality of column pixel groups 40 disposed on the substrate 20.

Specifically, each row of pixel group 30 includes a row of pixel units 50, at least one scanning line 31 corresponding to a row of pixel units 50, and at least one repair line 32 parallel to the scanning line 31 and spaced apart from the scanning line 31, where the repair line 32 is electrically connected to the scanning line 31 through a connection line 60.

Specifically, the column pixel group 40 includes a column of pixel units 50 and at least one data line 41 disposed corresponding to a column of the pixel units 50.

As shown in fig. 3, an orthogonal projection of the connection line 60 on the substrate board 20 does not coincide with an orthogonal projection of the data line 41 on the substrate board 20.

By arranging at least one repair line 32 parallel to the scanning line 31, when the scanning line 31 and the data line 41 are short-circuited, a short-circuit point can be cut off, and the repair line 32 and the connecting line 60 are used as a signal transmission channel, so that the pixel unit 50 can normally work, the repair function realized by a double-span structure can be realized by arranging less connecting lines 60, the layout space is saved, and the display panel with high pixel density is easy to realize.

It should be noted that, referring to fig. 3, the overlapping point of the data line 41 and the scan line 31 and the repair line 32 is a node, wherein when a short circuit occurs at the node E or the node F, the gate lines on both sides of the short-circuited node are cut by using laser, and at this time, the connecting line 60 and the repair line 32 are used as a signal transmission path, and even if some pixel units 50 cannot be turned on, the operation of the entire array substrate is not substantially affected.

Further, in each row of pixel groups 30, the repair line 32 and the scan line 31 are electrically connected to the pixel unit 50.

The repair line 32 and the scan line 31 may both directly transmit signals to the pixel unit 50, and when one of the repair line 32 or the scan line 31 has a problem, the other may serve as a signal transmission channel, so that the pixel unit 50 may normally operate, and when a single node, such as the node a, the node B, the node C, the node D, the node E, or the node F, is short-circuited, both sides of the node where the short-circuit occurs may be cut off.

Specifically, in each of the row pixel groups 30, the number of the connection lines 60 is less than or equal to the number of the pixel units 50.

In one embodiment, as shown in fig. 4, in each of the row pixel groups 30, the connection lines 60 correspond to the pixel units 50 one to one, so that when a single node short circuit occurs at any position, effective repair can be performed and as few pixel units 50 as possible cannot be lit.

Specifically, the array substrate further includes an active layer 70 disposed on the substrate 20 and located at a different layer from the scanning line 31, and an orthographic projection of the repair line 32 on the substrate 20 is not overlapped with an orthographic projection of the active layer 70 on the substrate 20, so as to prevent the repair line 32 and the active layer 70 from overlapping to form a capacitor, which affects normal operation of the array substrate.

Further, an orthographic projection of the connecting line 60 on the substrate base plate 20 is not coincident with an orthographic projection of the active layer 70 on the substrate base plate 20.

Specifically, the repair lines 32 correspond to the scan lines 31 one to one. When the short circuit of the node is ensured, the number of the repairing lines 32 is reduced, and the space occupied by the repairing lines 32 is reduced.

Further, the repair line 32 is disposed in the same layer as the connection line 60 and the scan line 31.

In practical implementation, the repair line 32 may be located at a different level from the scan line 31, and the repair line 32 and the scan line 31 are electrically connected through a via.

In one embodiment, the repair line 32, the connection line 60 and the scan line 31 are formed in the same process, so that the number of process steps can be reduced, and the production cost can be saved.

Based on the array substrate, the invention further provides an OLED display panel, which includes the array substrate in any of the above embodiments and light emitting units disposed on the array substrate, where the light emitting units correspond to the pixel units 50 of the array substrate one to one.

The array substrate includes a substrate 20, and a plurality of row pixel groups 30 and a plurality of column pixel groups 40 disposed on the substrate 20.

Specifically, each row of pixel group 30 includes a row of pixel units 50, at least one scanning line 31 corresponding to a row of pixel units 50, and at least one repair line 32 parallel to the scanning line 31 and spaced apart from the scanning line 31, where the repair line 32 is electrically connected to the scanning line 31 through a connection line 60.

Specifically, the column pixel group 40 includes a column of pixel units 50 and at least one data line 41 corresponding to a column of the pixel units 50, and an orthogonal projection of the connection line 60 on the substrate 20 is not overlapped with an orthogonal projection of the data line 41 on the substrate 20.

By arranging the repair line 32 parallel to the scan line 31, when the scan line 31 and the data line 41 are short-circuited, a short-circuit point can be cut off, and the repair line 32 and the connecting line 60 are used as a signal transmission channel, so that the pixel unit 50 can normally work, the repair function realized by a double-span structure can be realized by arranging less connecting lines 60, the layout space is saved, and the display panel with high pixel density is easy to realize.

The invention has the beneficial effects that: by arranging the repair line 32 parallel to the scan line 31, when the scan line 31 and the data line 41 are short-circuited, a short-circuit point can be cut off, and the repair line 32 and the connecting line 60 are used as a signal transmission channel, so that the pixel unit 50 can normally work, the repair function realized by a double-span structure can be realized by arranging less connecting lines 60, the layout space is saved, and the display panel with high pixel density can be easily realized.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
