Referring to fig. 3, fig. 3 is a schematic structural diagram of a display panel according to an embodiment of the invention.
As shown in fig. 3, the display panel 100 of the present embodiment includes a plurality of scan lines 21, a plurality of data lines 22, and a plurality of light emitting units 301; the light emitting unit 301 includes a light emitting device D1 and a driving chip 30;
each row of light emitting units 301 corresponds to the scanning line 21, and each column of light emitting units 301 corresponds to the data line 22, the first power line 23 and the second power line 24 respectively;
the driving chip 30 is respectively connected to the scanning line 21, the data line 22, and the second power line 24 corresponding to the light emitting unit 301, and the second end of the light emitting device in the light emitting unit 301, and the first end of the light emitting device D1 is connected to the corresponding first power line 23. In an embodiment, the driving chip 30 may be an integrated module of a first transistor and a second transistor, and a specific connection manner of the first transistor and the second transistor may be shown in fig. 1. Of course, the specific structure of the driving chip 30 is not limited thereto. In one embodiment, the driving chip 30 is fixed to the display panel 100 by means of a patch, but the specific arrangement of the driving chip 30 is not limited.
In one embodiment, in order to reduce the number of overlapping between the traces, the driving chip 30 includes: a scan signal input terminal P1, a data signal input terminal P2, a power control terminal P3, a second power input terminal P4, a scan cascade terminal P5 and a data cascade terminal P6.

For example, the horizontally adjacent light emitting unit of the light emitting unit 301 on the left side of the first row is the light emitting unit on the right side of the first row. Wherein the vertically adjacent light emitting unit 301 is a light emitting unit adjacent to the light emitting unit 301 in a second direction. The second direction is parallel to the data line 22. For example, the vertically adjacent light emitting unit of the light emitting unit 301 above the first column is the light emitting unit below the first column. Wherein the first terminal of the light emitting device D1 may be an anode and the second terminal may be a cathode. The light emitting device D1 includes, but is not limited to, a micro organic light emitting diode, an organic light emitting diode.
In one embodiment, in order to reduce the length of the connection line and the transmission efficiency of the signal, the scan signal input terminal P1 may be opposite to the scan cascade terminal P5, i.e., the scan signal input terminal P1 may be symmetrically disposed with respect to the scan cascade terminal P5. The data signal input terminal P2 may be opposite to the data cascade terminal P6. The scanning cascade end is used for transmitting scanning signals, and the data cascade end is used for transmitting data signals, that is, the scanning cascade end and the data cascade end respectively transmit the scanning signals and the data signals downwards, so that the number of signal lines in a panel is reduced. The first power line is used for accessing a first power voltage and the second power line is used for accessing a second power voltage.
As shown in fig. 4, taking a single light emitting unit as an example, when the connection method is adopted, the number of overlapping between the wirings (shown by a dashed line frame in the figure) can be reduced, so that the register capacitance is reduced, and the power consumption is reduced. It will be understood, of course, that fig. 3 is given by way of example only and is not intended to limit the present invention. Although fig. 3 illustrates a display panel including two rows and two columns of light emitting units, the present invention is not limited thereto.
The embodiment encapsulates the first transistor, the second transistor, the capacitor and other required devices on the same chip, and the switch of the light-emitting device can be controlled by connecting the scanning signal, the data signal, the first power voltage and the second power voltage into the driving chip, so that the overlapping quantity between wires (shown by a dotted line frame in the figure) can be reduced, the capacitor is reduced, and the display effect is improved.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a display panel according to another embodiment of the present invention.
On the basis of the previous embodiment, in an implementation manner, as shown in fig. 5, the driving chip 30 further includes: the second power cascade terminal P9 and the second power cascade terminal P9 are connected to the second power access terminal P4 of the driving chip 30 corresponding to the vertically adjacent light emitting cells 301, so that the number of overlapping traces (as shown by the dashed oval frame in the figure) can be further reduced, and the storage capacitance can be further reduced. Wherein the second power input terminal P9 may be opposite to the second power cascade terminal P4 in order to reduce the length of the connection line and the transmission efficiency of signals, which is just an example and is not a limitation to the present invention. The second power cascade terminal P9 is used for transmitting the second power supply voltage VSS.
In another embodiment, as shown in fig. 6, the driving chip 30 further includes: a first power inlet terminal P7 and a first power cascade terminal P8. The first power supply inlet P7 is connected to the first power supply line 23 corresponding to the light emitting unit 301; the first power cascade terminal P8 is connected to the first power access terminal P7 of the driving chip 30 corresponding to the vertically adjacent light-emitting unit 301, so that no overlapping exists between the wires, and the storage capacitance is effectively reduced. Wherein the first power input terminal P7 may be opposite to the first power cascade terminal P8 in order to reduce the length of the connection line and the transmission efficiency of signals, which is just an example and is not a limitation to the present invention. The first power cascade terminal P8 is used for transmitting a first power voltage VDD, wherein the first power voltage VDD is greater than a second power voltage VSS.
Wherein, in order to improve the uniformity of the luminance and reduce the impedance of the connection line, the first terminal of the light emitting device D1 in the light emitting cell 301 is connected to the first power cascade input terminal P8; the first power cascade terminal P8 and the power control terminal P3 are disposed adjacent to each other.
In another embodiment, in order to improve the uniformity of the luminance and reduce the impedance of the connection line, the first power input terminal P7 and the power control terminal P3 may be adjacently disposed.
In an embodiment, the scan lines 21, the data lines 22, the first power lines 23, and the second power lines 34 are disposed on the same layer, and the materials are the same, and since all the wires are not crossed in the display panel, the wires can be prepared from the same metal layer, thereby reducing the thickness of the display panel, simplifying the manufacturing process, and reducing the production cost.
In one embodiment, as shown in fig. 7, the display panel 100 of the present embodiment may include a substrate 41, a first metal layer 42, a first insulating layer 43, an anode 44, and further include an organic light emitting layer and a cathode. The first metal layer 41 includes a scan line, a data line, a first power line, and a second power line, and the material of the first metal layer 41 may include, but is not limited to, at least one of molybdenum, titanium, and copper, and the specific material is not limited. The first metal layer 41 may be a single layer film or a multilayer film.
Because the pins of the second power line or the pins of the first power line are also arranged on the driving chip 30, the number of overlapping between the wires (shown by a dotted line frame in the figure) can be further reduced, thereby reducing the storage capacitance and improving the display effect.
As shown in fig. 8, the present embodiment further provides a display screen 200, which includes any one of the display panels 100, and the display screen may further include a touch layer 120. In one embodiment, the touch layer 120 may be disposed above the flexible display panel, but the disposing manner of the touch layer 120 is not limited thereto.
