The embodiment of the application provides an OLED display panel and a display device, and the OLED display panel is described in detail below.
Referring to fig. 1, fig. 1 is a schematic view of a first partial structure of an OLED display panel 10 according to an embodiment of the present disclosure. The OLED display panel 10 includes a plurality of scan line groups 101, a plurality of data lines 102, a plurality of scan line groups 101, and a plurality of light emitting cells 103 defined by the plurality of data lines 102 crossing each other. The plurality of scanning line groups 101 are arranged in a column direction, which is a direction extending along the y-axis in the figure. Each Scan line group 101 includes a first Scan line 1011, a second Scan line 1012 and a third Scan line 1013, and the nth row is illustrated as an example, the first Scan line 1011 receives the Scan signal Scan (n-1) in the previous row, the second Scan line 1012 receives the Scan signal Scan (n) in the current row, and the third Scan line 1013 receives the Scan signal Scan (n +1) in the next row. The plurality of data lines 102 are arranged in a row direction, which is a direction extending along the x-axis in the figure. The plurality of light emitting units 103 are arranged in an array. At least one data line 102 is connected to two columns of light emitting units 103. In the two columns of light emitting units 103, the light emitting units 103 located in the same row include a first light emitting unit 1031 and a second light emitting unit 1032, the first light emitting unit 1031 is connected to the first scanning line 1011 and the second scanning line 1012, and the second light emitting unit 1032 is connected to the second scanning line 1012 and the third scanning line 1013.
In fig. 1, the row direction (i.e., the direction extending along the x-axis) and the column direction (i.e., the direction extending along the y-axis) are illustrated as being perpendicular to each other, but the row direction and the intersection angle are not limited in the present application.
According to the OLED display panel 10 provided in the embodiment of the present application, by designing the connection manner between the scan lines 102 and the light emitting units 103, the light emitting units 103 in the same row do not start to operate at the same time, that is, do not receive signals from the data lines 102 at the same time. Thus, the two columns of light emitting units 103 share the data lines 102, and the number of the data lines 102 on the OLED display panel 10 can be reduced. Due to the fact that the number of the data lines 102 is reduced, the distance between the data lines 102 is increased, the precision requirement of a binding process is lowered, and the short-circuit risk of the data lines 102 can be reduced.
When the light emitting units 103 are in even rows, each data line 102 is connected to two rows of light emitting units 103. When the light emitting units 103 are in odd rows, one data line 102 is connected to one row of light emitting units 103, and the other data lines 102 are connected to two rows of light emitting units 103. Therefore, the scheme provided by the application can meet the requirements of different display panels, and the effects of reducing the data lines 102 and reducing the binding process precision of the panel can be achieved on the display panels of the light-emitting units with different specifications.
In a row of light emitting units 103 connected to one data line 102, the light emitting units 103 are connected to the first scanning line 1011 and the second scanning line 1012, or the light emitting units 103 are connected to the second scanning line 1012 and the third scanning line 1013.

The first scan line 1011, the second scan line 1012, and the third scan line 1013 are all disposed on the same layer as the capacitor substrate layer 105. The first scan line 1011, the second scan line 1012 and the third scan line 1013 are all connected to the gate layer 106 through the via 108. The data line 102 and the source and drain layers 107 are arranged on the same layer, and are connected to the gate layer 106 through the via hole 108 by the source and drain layers 107, the via hole 108 is completed synchronously during other via hole processes, and the whole array process does not need to be changed. The first scan line 1011, the second scan line 1012 and the third scan line 1013 are disposed on the capacitor substrate layer 105, so that the signal line distribution on the gate layer 106 can be reduced, the requirement for the precision of the binding process can be reduced, the production difficulty can be reduced, and the quality of the display panel can be improved. The film layer structure provided in the examples of the present application is only used as an example to illustrate one embodiment of the present application, and is not used as a limitation to the present application.
Referring to fig. 3, fig. 3 is a schematic diagram of a second partial structure of the OLED display panel 10 according to the embodiment of the present disclosure. The OLED display panel 10 includes a plurality of scan lines 101, a plurality of data lines 102, a plurality of scan lines 101, and a plurality of light emitting cells 103 defined by the data lines 102 crossing each other. The plurality of scanning lines 101 are arranged in a column direction, and the plurality of data lines 102 are arranged in a row direction, the column direction being a direction extending along the y-axis in the figure, and the row direction being a direction extending along the x-axis in the figure. The plurality of light emitting units 103 are arranged in an array. At least one data line 102 is connected to two columns of light emitting units 103. In the two columns of light emitting units 103, the light emitting units 103 in the same row include a first light emitting unit 1031 and a second light emitting unit 1032, the first light emitting unit 1031 is connected to the scanning line 1012 in the current row and the scanning line 1011 in the previous row, and the second light emitting unit 1032 is connected to the scanning line 1012 in the current row and the scanning line 1013 in the next row. Connection explanation is made in fig. 3 taking the second row of light emitting cells 103 as an example, and connection of the first row of light emitting cells 103 to the scan line data line is not shown.
In fig. 3, the row direction (i.e., the direction extending along the x-axis) and the column direction (i.e., the direction extending along the y-axis) are illustrated as being perpendicular to each other, but the row direction and the intersection angle are not limited in the present application.
The OLED display panel 10 includes an organic layer, a capacitor substrate layer, a gate layer, a source drain layer, and a via hole, which are sequentially stacked, and the scan line 101 and the gate layer are disposed on the same layer. Since the scan lines of the OLED display panel 10 provided in this embodiment have a wider line pitch and a smaller risk of short circuit, the process can be simplified by disposing the scan lines and the gate layer in the same layer. The scan line 101 may also be disposed on the same layer as the capacitor substrate layer 105, and the specific arrangement of the scan line 101 may be determined according to different OLED display panel requirements and production process flows, which is not limited in this application.
The structure of the OLED display panel 10 provided in this embodiment does not change the arrangement of the scan lines 101, and does not need to change the scan line setting process. In this embodiment, the effect of reducing the number of the data lines 102 can be achieved by only changing the connection manner of the scan lines 101 and the light emitting units 103, and the manufacturing process is convenient.

An output terminal of the second transistor T2 is connected to an input terminal of the first transistor T1 through a sixth node N6.
The gate of the third transistor T3 is connected to the second scan line 1012 and receives the present row scan signal scan (n). An input terminal of the third transistor T3 is connected to an output terminal of the fourth transistor T4 through a third node N3. An output terminal of the third transistor T3 is connected to an output terminal of the first transistor T1 through a fifth node N5.
The gate of the fourth transistor T4 is connected to the first Scan line 1011 and receives the Scan signal Scan (n-1) of the previous line. An input terminal of the fourth transistor T4 is connected to the third voltage VI and an input terminal of the seventh transistor T7 through the second node N2. An output terminal of the fourth transistor T4 is connected to an input terminal of the third transistor T3 through a third node N3.

The light emitting units in the OLED display panel 10 have the same structure, and are not described herein again. However, the scan lines connected to the light emitting units in the same row connected to the same data line are different, and the scan signals received are different. Specifically, the second transistor T2, the third transistor T3 and the seventh transistor T7 of the first light emitting unit are connected to the present row Scan signal Scan (n), and the fourth transistor T4 of the first light emitting unit is connected to the previous row Scan signal Scan (n-1).

Referring to fig. 5, fig. 5 is a signal waveform diagram of the light emitting unit 103 according to the embodiment of the present disclosure. In the first period t1, Scan (n-1) is a low level signal, and the first light emitting unit performs circuit reset. In the second stage t2, scan (n) is a low level signal, the first light emitting unit performs circuit compensation, and the second light emitting unit performs circuit reset. In the third stage t3, Scan (n +1) is a low level signal, the first light emitting unit performs anode reset, and the second light emitting unit performs circuit compensation. The first light-emitting unit and the second light-emitting unit have a front-back difference of a clock signal, so that data line signals can be written in successively. The emission control signal em (n) is at a high level at the time of the circuit reset, the circuit compensation, and the anode reset of the pixel compensation circuit operation, and turns off the fifth transistor T5 and the sixth transistor T6. The embodiment of the present application has been described by taking the P-type transistor as an example, and thus the fifth transistor T5 and the sixth transistor T6 are turned off when the emission control signal em (n) is at a high level, but not by way of limitation.
The timing signal adopted by the light-emitting unit provided by the embodiment of the application does not start to work at the same timing for the light-emitting units in the same row, namely, does not receive the data line signal at the same time. The light-emitting units sharing the data line in the same row have a difference of one clock signal, so that the sharing of the data line can be realized, and the data line is halved.
The present embodiment provides a display device 100, and fig. 6 is a schematic structural diagram of the display device 100 in the present embodiment. The display device 100 includes the OLED display panel 10 and the encapsulation structure 20, and the display device 100 may further include other devices. The package 20 and other devices and their assembly in the embodiments of the present application are well known to those skilled in the art and will not be described in detail herein.
The display device 100 provided by the embodiment of the application comprises an OLED display panel and an encapsulation structure. According to the OLED display panel, the connection mode of the scanning lines and the light-emitting units is designed, so that the light-emitting units in the same row do not start to work at the same time sequence any more, namely, do not receive data line signals at the same time. Therefore, the two columns of light-emitting units share the data lines, and the number of the data lines on the OLED display panel can be reduced. Because the number of the data lines is reduced, the distance between the data lines is increased, the requirement on the binding process precision is lowered, and the risk of short circuit of the data lines can be reduced.
