The fan-out area 300 includes a single scan line layer and a single data line layer, which are stacked and arranged. However, in the case where the resolution of the display area 100 is increased, the number of sub-pixels is increased, and thus the number of scan lines of the scan line layer and the number of data lines of the data line layer are correspondingly increased. If the plurality of scan lines are all disposed on the same scan line layer and the plurality of data lines are all disposed on the same data line layer in the related art, the area of the scan line layer or the data line layer needs to be increased, which leads to an increase in the area of the fan-out area 300, and is not beneficial to the development trend of the narrow frame of the electronic device.

Based on this, this disclosure provides a display panel, and this display panel is provided with three-layer metal and walks the line layer, and this three-layer metal walks the line layer and includes multilayer data line layer and/or multilayer scanning line layer to this is walked the line through increasing the metal of the line layer of walking the number of sharing the fan-out lead district, is favorable to reducing the area occupied of fan-out lead district, is favorable to the narrow frame development of electronic equipment.

As shown in fig. 2, the present disclosure provides a display panel including a substrate 1, a first metal wiring layer 2, a second metal wiring layer 3, a third metal wiring layer 4, an insulating layer 5A, an insulating layer 5B, and an insulating layer 5C. The substrate 1 includes a display area 11 and a non-display area 12 outside the display area 11, the display area 11 may be provided with a plurality of sub-pixels and a pixel driving circuit for controlling the sub-pixels, the non-display area 12 is connected to the display area 11, the non-display area 12 includes a fan-out lead area 121, and a driving chip and the sub-pixels for driving the display panel may be turned on through a data line and a scan line disposed above the fan-out lead area 121 to realize control of the sub-pixels.

The first metal wiring layer 2, the second metal wiring layer 3, the third metal wiring layer 4, the insulating layer 5A, the insulating layer 5B and the insulating layer 5C are vertically arranged above the substrate 1 along the direction vertical to the substrate 1, the fan-out lead area 121 of the substrate 1 is arranged on the first metal wiring layer 2, the insulating layer 5A is arranged between the first metal wiring layer 2 and the second metal wiring layer 3, the insulating layer 5B is arranged between the second metal wiring layer 3 and the third metal wiring layer 4, and the insulating layer 5C is further arranged on one side, away from the insulating layer 5B, of the third metal wiring layer 4, so that the insulating arrangement of the first metal wiring layer 2, the second metal wiring layer 3 and the third metal wiring layer 4 is realized.

The first metal routing layer 2 may be a data routing layer, the second metal routing layer 3 and the third metal routing layer 4 are scanning routing layers, and based on the scanning routing layers, a plurality of scanning wires can be arranged through the double-layer scanning routing layers, so that the area requirement of the scanning wire arrangement on the fan-out lead area 121 is reduced, the area of the fan-out lead area 121 is reduced, and the development trend of a narrow frame of the electronic device is facilitated.

Note that, the insulating layers 5A, 5B, and 5C may be disposed at least in the fan-out lead region 121, and the insulating layers 5A, 5B, and 5C may be extended to other regions than the display region 12 and to a partial region of the display region 11, if necessary. The insulating layers 5A, 5B and 5C located in the display region 11 and the non-display region 12, respectively, may be formed by one process. Similarly, to facilitate simultaneous processing of the display area and the non-display area of the display panel, the first metal routing layer 2, the second metal routing layer 3, and the third metal routing layer 4 may be completed with the same layer metal of the display area 11 through a single reticle process.

In the above embodiment, the display panel includes the first metal wiring layer 2, the second metal wiring layer 3 and the third metal wiring layer 4, and in other embodiments, the display panel may include four or more metal wiring layers, where the four or more metal wiring layers and the insulating layer are stacked along the direction perpendicular to the substrate, at least one insulating layer is disposed between two adjacent metal wiring layers, any metal wiring layer is connected to the substrate, and the four or more metal wiring layers may include a plurality of data line layers and a single scan line layer, or a plurality of data line layers and a plurality of scan line layers, or a plurality of scan line layers and a single data line layer.

Of course, when the display panel includes the first metal wiring layer 2, the second metal wiring layer 3 and the third metal wiring layer 4, the display panel may include two scan line layers and a single data line layer, or may include a double data line layer and a single scan line layer, and the stacking direction of the specific data line layer and the scan line layer in the direction perpendicular to the substrate 1 may be designed according to requirements. When the display panel includes the first metal routing layer 2, the second metal routing layer 3 and the third metal routing layer 4, as shown in fig. 2, a single-layer insulating layer may be disposed between two adjacent metal routing layers, and optionally, multiple layers of insulating layers may also be disposed between two adjacent metal routing layers, which may be specifically designed according to needs, which is not limited in this disclosure.

In the above embodiments, since the resolution of the display panel increases, the number of data lines and scan lines increases, which may result in an increase in the load of metal traces disposed on the data line layer and the scan line layer, affecting the display performance and touch performance of the display panel. Thus, as shown in fig. 3-5, each metal trace layer includes a plurality of metal traces, two metal traces located in different metal trace layers and transmitting the same type of signals are connected in parallel through conductive vias 6 provided in the insulating layer, and form a group of metal traces, and one or more groups of metal traces may be formed between the two metal trace layers. Therefore, by connecting the metal wires for transmitting the same type of signals in parallel, the resistance is reduced, the load can be reduced, and the influence of the resistance load on the display performance and the touch performance of the display panel is reduced.

Alternatively, one set of metal wires may be used for transmitting data signals, for example, one or more sets of metal wires may be disposed between two data wire layers, and each set of metal wires is connected in parallel through a conductive hole 6 disposed in an insulating layer. Alternatively, one set of metal wires may be used to transmit the scan signal, for example, one or more sets of metal wires may be disposed between two scan line layers, and each set of metal wires is connected in parallel through a conductive hole 6 disposed in the insulating layer. The load on the scanning line is relatively large, so that at least one group of metal wires in a display panel is formed by two scanning line layers, thereby efficiently reducing the load.

For convenience of explanation, the following embodiments will take a multi-layer scan line layer as an example. For example, as shown in fig. 3 to 5, the first metal routing layer 2 and the third metal routing layer 4 are taken as scan line layers, and assuming that the first metal routing layer 2 is a first scan line layer, the first scan line layer includes a plurality of first scan wires, the third metal routing layer 4 is a second scan line layer, the second scan line layer includes a plurality of second scan wires, and the plurality of first scan wires and the plurality of second scan wires may be connected in parallel through the conductive holes 6 in a one-to-one correspondence manner. For example, in the illustration, the first scanning line layer includes three scanning lines, the second scanning line layer includes three scanning lines, and the three scanning lines of the first scanning line layer and the three scanning lines of the second scanning line layer are connected in parallel through the conductive holes 6 in a one-to-one correspondence.

In the embodiment shown in fig. 3, the display panel includes two scan line layers, and in other embodiments, the display panel may include three or more scan line layers, where at least one group of scan lines connected in parallel through the conductive holes 65 may be disposed between any two scan line layers, or assuming that two scan line layers including at least one group of scan lines connected in parallel through the conductive holes 6 are one group, one or more groups of scan line groups may be disposed between the three or more scan line layers, and the same scan line layer may be respectively grouped with multiple other scan line layers into one group of scan line groups, so as to form multiple scan line groups, or the same scan line layer may be grouped with only the corresponding other scan line layers into one group of scan line groups.

In the following embodiments, taking the first scan line layer and the second scan line layer as examples, a scheme of parallel connection of scan lines of different layers through the conductive vias 6 is specifically described, and a scheme of parallel connection of scan lines of other layers through the conductive vias 6 can refer to the first scan line layer and the second scan line layer, which will not be described in detail later.

Alternatively, as shown in fig. 3, a plurality of first scan lines and a plurality of second scan lines may be disposed side by side in the same direction, for example, all disposed along the horizontal direction in fig. 3, in the direction perpendicular to the substrate 1, that is, in the vertical direction in fig. 3, the orthographic projection of each first scan line and the orthographic projection of one of the second scan lines at least partially overlap, and the first scan line and the second scan line, at least partially overlapped in orthographic projection, are connected in parallel through the conductive via 6. Based on this scheme, as shown in fig. 3, setting vertical conduction on the insulating layer 5B can realize that each first scanning wire is connected in parallel with the corresponding second scanning wire, and the difficulty in processing the conductive holes 6 can be reduced. Of course, in other embodiments, a set of first scan guide and second scan guide wires may naturally be connected in parallel using a curved, or bent, or slanted conductive aperture 6.

Alternatively, the plurality of first scan lines and the plurality of second scan lines may be disposed side by side in the same direction, and in the direction perpendicular to the substrate 1, orthographic projections of the plurality of first scan lines and the plurality of second scan lines may be disposed side by side, in which case a group of first scan lines and second scan lines may be conducted through the bent conductive vias 6, or a bent or inclined conductive via 6 may be employed, which is not limited in this disclosure.

In the embodiment shown in fig. 3, a data line layer and an insulating layer are disposed between the first scan line layer and the second scan line layer; the first scanning line layer and the second scanning line layer can be provided with one or more data line layers and one or more insulating layers, and the first scanning line layer and the second scanning line layer can be designed according to requirements. In other embodiments, as shown in fig. 4 and fig. 5, only the insulating layer may be spaced between the first scan line layer and the second scan line layer, as shown in fig. 4, the first scan line and the second scan line may be connected in parallel through vertical conductive holes, or as shown in fig. 5, the first scan line and the second scan line may be connected in parallel through bent conductive holes, optionally, may be connected in parallel through bent, inclined conductive holes 6, and may be specifically designed as needed. The orthographic projections of the first scanning wire and the second scanning wire on the substrate 1 may be separated or may be partially overlapped.

Taking fig. 6 as an example, taking the first metal wiring layer 2 as a first scanning line layer, the second metal wiring layer 3 as a data line layer, and the third metal wiring layer 4 as a second scanning line layer, where the data line layer is disposed between the first scanning line layer and the second scanning line layer, so that in the process of forming the display panel, the first scanning line layer can be formed along with the metal gate of the display area 11 by using the same mask patterning process, and the data line layer can be formed along with the metal source/drain of the display area 11 by using the same mask patterning process, and only one mask needs to be added for forming the third metal wiring layer 4, which is beneficial to simplifying the forming process of the display panel in the disclosure by multiplexing the conventional process.

In the above embodiments, as shown in fig. 4 to 6, each group of parallel metal traces is connected in parallel through a plurality of conductive vias 6, and the plurality of conductive vias 6 are uniformly arranged, for example, a group of parallel scan wires is connected in parallel through a plurality of conductive vias 6 that are uniformly arranged, or a group of parallel data wires is connected in parallel through a plurality of conductive vias 6 that are uniformly arranged. In this way, a uniform reduction of the resistance on the scan lines can be achieved. Alternatively, the uniform arrangement among the plurality of conductive holes 6 can be realized by designing a fixed interval distance between the adjacent conductive holes 6, and in order to avoid the data line layer arranged between the scanning line layers, the uniform arrangement can be realized by arranging the special-shaped conductive hole 6 structure. Alternatively, since the metal traces of each metal trace layer are regularly arranged, the uniform arrangement among the conductive vias 6 can be achieved by controlling the number of the metal traces spaced between the adjacent conductive vias 6.

In the above embodiments, in order to make the arrangement of the conductive vias 6 avoid other metal trace layers, the metal traces disposed on each metal trace layer are used to transmit the same type of signals, and assuming that a group of metal traces connected in parallel in the above embodiments transmit signals of the first type, at least one metal trace layer of the above at least three metal trace layers transmits signals of the second type. In the direction perpendicular to the substrate 1, the orthographic projection of the conductive vias 6 between any group of metal tracks transmitting signals of the first type is separated from the orthographic projection of the metal tracks of the metal track layer transmitting signals of the second type.

Still referring to fig. 4, assume that the first type of signal is a scanning signal, the second type of signal is a data signal, the first metal trace layer 2 is a first scan line layer, the first scan line layer includes a plurality of first scan wires, and the third metal trace layer 4 is a second scan line layer. Then, the projection of the conductive holes of the first scanning wire and the second scanning wire which are connected in parallel is separated from the orthographic projection of the data wiring on the data wire layer; in other embodiments, the orthographic projection of the conductive holes connected in parallel with a group of data wires is separated from the orthographic projection of the scanning wires, so that the display panel fault caused by the connection of the metal wires transmitting different types of signals through the conductive holes 6 can be avoided.

Wherein, a plurality of conductive holes 6 between any group of metal wires for transmitting the first type of signals are connected in parallel, and the parallel direction of a plurality of metal wires of a metal wire layer for transmitting the second type of signals is the same as the parallel direction of the conductive holes 6; in the direction perpendicular to the substrate 1, at least one metal track for transmitting signals of the second type is located between the orthographic projections of two adjacent conductive vias.

Still regard first kind signal as scanning signal, second kind signal is the data signal, and first metal wiring layer 2 is first scanning line layer, and first scanning line layer includes many first scanning wires, and third metal wiring layer 4 is the second scanning line layer for the example, and the parallel conductive hole of multirow has been arranged in the horizontal direction in fig. 6, and each row conductive hole can connect in parallel a set of metal wiring of transmission scanning signal, can be provided with three metal wirings of transmission data signal between adjacent conductive hole. In other embodiments, each row of conductive vias may be connected in parallel with a set of metal traces that transmit data signals, and three metal traces that transmit scan signals may be provided between adjacent conductive vias. Based on this, on the one hand, the positions of the conductive holes 6 can be guaranteed to avoid other metal wires, and on the other hand, the uniform arrangement of the conductive holes 6 can be realized.

It should be noted that, the foregoing description is exemplified by a parallel connection manner between the first scan line layer and the second scan line layer of the first scan line layer, and in other embodiments, parallel connection may be implemented between the data lines of the multi-layer data line layer, and the specific implementation manner may refer to the embodiment of the scan line layer, which is not described herein again.

Based on the technical scheme of the disclosure, a display device is further provided, and the display device comprises a driving chip, a circuit board and the display panel in any implementation. The driving chip is respectively communicated with each metal wiring layer so as to send scanning signals to the scanning line layers and data signals to the data line layers through the driving chip. The circuit board is communicated with the driving chip, and the circuit board can be connected to a main board of the electronic equipment, so that a control signal is sent to the driving chip through the main board, and the driving chip is further controlled to send scanning signals and data signals.
