For example, when a green display screen is displayed), the brightness of each light-emitting unit row is uniform, which improves the situation that if light-emitting devices of the same light-emitting color in the same drive circuit row are all electrically connected to the same data line, and different drive circuit rows are connected to different data lines (for example, the first drive row is electrically connected to the first data line, and the second drive row is electrically connected to the second data line), the parasitic capacitance generated when different drive circuits are connected to different data lines will be different, and the electrical signals supplied to the light-emitting devices will be different, resulting in different light-emitting brightness of the light-emitting device rows, and thus causing the undesirable problem of alternating bright horizontal lines and dark horizontal lines when displaying a monochrome screen; and the second drive circuit in the second drive group is electrically connected to a different data line than the second drive circuit in the first drive group, so that in each column of light-emitting devices of the same light-emitting color, when the display panel displays a monochrome screen, the brightness of each light-emitting unit column can also be made uniform, thereby improving the undesirable problem of alternating bright vertical lines and dark vertical lines when the display panel displays a monochrome screen.

An embodiment of the present invention provides a display panel, comprising: a base substrate, and a plurality of light-emitting units located on one side of the base substrate, wherein each light-emitting unit includes a driving circuit T and a light-emitting device F electrically connected to the pixel driver; specifically, in each light-emitting unit, the light-emitting device can be located on the side of the driving circuit away from the base substrate; combined with Figure 1 and Figure 2 As shown, Figure 1 Each driving circuit T in a row is electrically connected to Figure 2 The light emitting devices F strung together by a horizontal dotted line are specifically, for example, Figure 1 The first driver circuit T from the left in the first row is Figure 2 The first light emitting device F from the left on the first horizontal dotted line is electrically connected to the second driving circuit T from the left in the first row. Figure 2 The second light emitting device F from the left on the first horizontal dotted line is electrically connected to the third driving circuit T from the left on the first row.

Figure 2 The fourth light emitting device F from the left on the first horizontal dotted line corresponds to the electrical connection ...; similarly, for Figure 1 The first driver circuit T from the left in the second row is Figure 2 The first light emitting device F on the second horizontal dotted line from the left corresponds to the electrical connection. Figure 1 The second drive circuit T from the left in the second row is Figure 2 The second light emitting device F from the left on the second horizontal dotted line corresponds to the electrical connection. Figure 1 The third drive circuit T from the left in the second row is Figure 2 The third light emitting device F from the left on the second horizontal dotted line corresponds to the electrical connection. Figure 1 The fourth drive circuit T from the left in the second row is Figure 2 The fourth light emitting device F from the left on the second horizontal dotted line is electrically connected to ...;

[0041] The plurality of driving circuits include: a first driving row S1 and a second driving row S2 arranged along a first direction C1, the first driving row S1 including a plurality of first driving groups S11 periodically arranged along a second direction C2, the second driving row S2 including a plurality of second driving groups S21 periodically arranged along the second direction C2, wherein the first driving group S11 and the second driving group S21 each include four driving circuits T, and a first data line D1 and a second data line D2 are provided in an area where each driving circuit T is located;

[0042] In the first driving group S11, the light emitting devices F electrically connected to the second and fourth driving circuits T parallel to the second direction C2 have the same light emitting color, and one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2; specifically, for example, in combination Figure 1 and Figure 2 As shown, Figure 1 The second and fourth drive circuits T from the left in the first row correspond to the electrical connections Figure 2 The second and fourth light-emitting devices F from the left on the first horizontal dotted line have the same luminous color, for example, both are green light-emitting devices G1 / G2 emitting green light, then Figure 1 One of the second and fourth driving circuits T from the left in the first row is connected to the first data line D1, and the other is electrically connected to the second data line D2. Specifically, for example, Figure 1 In the first driving group S11, the second driving circuit T is electrically connected to the first data line D1, and the fourth driving circuit T is electrically connected to the second data line D2. Alternatively, for example, Figure 3 In the embodiment, the second driving circuit T in the first driving group S11 is electrically connected to the second data line D2, and the fourth driving circuit T is electrically connected to the first data line D1. Specifically, for ease of understanding, the light-emitting unit where the driving circuit T connected to the first data line D1 is located can be regarded as a type A light-emitting unit, and the light-emitting unit where the driving circuit T connected to the second data line D2 is located can be regarded as a type B light-emitting unit.

[0043] In the second driving group S21, the light emitting devices F electrically connected to the second and fourth driving circuits T parallel to the second direction C2 emit the same color as the light emitting devices F electrically connected to the second driving circuit T in the first driving group S11; in the second driving group S21, one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2, and the second driving circuit T in the second driving group S21 is electrically connected to a different data line than the second driving circuit T in the first driving group S11. Specifically, in combination Figure 1 As shown, the second and fourth drive circuits T in the second row are electrically connected to each other. Figure 2The second and fourth light-emitting devices F from the left on the second horizontal dotted line have the same luminous color as the second and fourth light-emitting devices F from the left on the first horizontal dotted line. Specifically, for example, the four light-emitting devices F are all green light-emitting devices G1 / G2 that emit green light. Then, in the second driving group S21, one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. Specifically, for example, Figure 1 In the second driving group S21, the second driving circuit T is electrically connected to the second data line D2, and the fourth driving circuit T is electrically connected to the first data line D1; or, for example, Figure 3 In the second driving group S21, the second driving circuit T is electrically connected to the first data line D1, and the fourth driving circuit T is electrically connected to the second data line D2.

[0044] In the embodiment of the present invention, in the first driving group S11, the light emitting devices F electrically connected to the second and fourth driving circuits T have the same light emitting color, and one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. This allows the driving circuits T corresponding to the light emitting devices F of the same light emitting color in the first driving row S1 to be alternately connected to the first data line D1 and the second data line D2, that is, the A-type light emitting units and the B-type light emitting units are alternately distributed, as shown in FIG. Figure 2 As shown by the first horizontal solid line in the figure; in the second driving group S21, the light emitting colors of the light emitting devices F electrically connected to the second and fourth driving circuits T parallel to the second direction C2 are the same as the light emitting colors of the light emitting devices F electrically connected to the second driving circuit T in the first driving group S11. In the second driving group S21, one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. This allows the driving circuits T corresponding to the light emitting devices F of the same light emitting color in the second driving row S2 to be alternately electrically connected to the first data line D1 and the second data line S2, that is, the A-type light emitting units and the B-type light emitting units are alternately distributed, as shown in FIG. Figure 2As shown by the second horizontal solid line in the figure, when the display panel displays a monochrome image (for example, a green display image), the brightness of each light-emitting unit row is uniform. If the light-emitting devices of the same light-emitting color in the same drive circuit row are all electrically connected to the same data line, and different drive circuit rows are connected to different data lines (for example, the first drive row is electrically connected to the first data line, and the second drive row is electrically connected to the second data line), the parasitic capacitance generated when different drive circuits are connected to different data lines will be different, and the electrical signals supplied to the light-emitting devices will be different, resulting in different luminous brightness of the light-emitting device rows, and thus when displaying a monochrome image, there will be an undesirable problem of alternating distribution of bright horizontal lines and dark horizontal lines; and the second drive circuit T in the second drive group S21 is electrically connected to a different data line than the second drive circuit T in the first drive group S11. In each column of light-emitting devices of the same light-emitting color, the A-type light-emitting units and the B-type light-emitting units are alternately arranged, as shown in FIG. Figure 2 As shown by the vertical solid line, when the display panel displays a monochrome image, the brightness of each light-emitting unit column can be made uniform, thereby improving the problem of alternating distribution of bright vertical lines and dark vertical lines when the display panel displays a monochrome image.

[0045] It should be noted that Figure 1 The purpose is to schematically illustrate the arrangement of the driving circuit, and further the driving circuit T is represented by a block area. The present invention is not limited thereto. In a specific implementation, the driving circuit T may include a structure including multiple thin film transistors and capacitors for driving the light emitting device to emit light. Similarly, Figure 2 Only the pattern of the main film layer (for example, the anode) in the light-emitting device is used to schematically indicate the location of the light-emitting device. The light-emitting device in the embodiment of the present invention is not limited to this. The light-emitting device may also include multiple other film layers, for example, an anode layer, a hole injection layer, a hole transport layer, an electron blocking layer, a light-emitting layer, a hole blocking layer, an electron transport layer, an electron injection layer, and a cathode.

[0046] In one possible embodiment, combining Figures 1-8 As shown, Figure 6 for Figure 5 The corresponding light emitting device arrangement diagram, Figure 8 For Figure 7 The corresponding light-emitting device arrangement diagram shows that in the first driving group S21, the light-emitting devices electrically connected to the first and third driving circuits T parallel to the second direction C2 have different luminous colors. Specifically, for example, in the first driving group S21, the light-emitting device electrically connected to the first driving circuit T is a blue light-emitting device B that emits blue light, and the light-emitting device electrically connected to the third driving circuit T is a red light-emitting device R that emits red light; one of the first and third driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. Specifically, for example, Figure 1 and Figure 3As shown, the first driving circuit T is electrically connected to the first data line D1, and the third driving circuit T is electrically connected to the second data line D2, or, for example, as shown Figure 5 and Figure 7 As shown, the first driving circuit T is electrically connected to the second data line D2, and the third driving circuit T is electrically connected to the first data line D1.

[0047] In one possible embodiment, combining Figures 1-8 As shown, in the second driving group S21, the light emitting devices F electrically connected to the first and third driving circuits T parallel to the second direction C2 have different luminous colors. Specifically, for example, in the second driving group S21, the light emitting device F electrically connected to the first driving circuit T is a light emitting device R that emits red light, and the light emitting device F electrically connected to the third driving circuit is a light emitting device B that emits blue light. One of the first and third driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. The first driving circuit T in the second driving group S21 is electrically connected to a different data line than the first driving circuit T in the first driving group S11. Specifically, for example, in the second driving group S21, for example, Figure 1 and Figure 3 As shown, the first driving circuit T is electrically connected to the second data line D3, and the third driving circuit T is electrically connected to the first data line D1, or, for example, as shown Figure 5 and Figure 7 As shown, in the second driving group S21, the first driving circuit T is electrically connected to the first data line D1, and the third driving circuit T is electrically connected to the second data line D2.

[0048] In one possible embodiment, combining Figures 1-8 As shown, in the second driving group S21, the light-emitting color of the light-emitting device electrically connected to the first driving circuit T parallel to the second direction C2 is the same as the light-emitting color of the light-emitting device electrically connected to the third driving circuit T in the first driving group S11, for example, both are red light-emitting devices R that emit red light; in the second driving group S21, the light-emitting color of the light-emitting device F electrically connected to the third driving circuit T parallel to the second direction C2 is the same as the light-emitting color of the light-emitting device F electrically connected to the first driving circuit T in the first driving group S11, for example, both are blue light-emitting devices B that emit blue light.

[0049] In one possible implementation, Figure 1 or Figure 5 As shown, in the first driving group S11, the second driving circuit T is electrically connected to the first data line D1, and the fourth driving circuit T is electrically connected to the second data line D2; in the second driving group S21, the second driving circuit T is electrically connected to the second data line D2, and the fourth driving circuit T is electrically connected to the first data line D1.

[0050] In one possible implementation, Figure 3 or Figure 7 As shown, in the first driving group S11, the second driving circuit T is electrically connected to the second data line D2, and the fourth driving circuit T is electrically connected to the first data line D1; in the second driving group S21, the second driving circuit T is electrically connected to the first data line D1, and the fourth driving circuit T is electrically connected to the second data line D2.

[0051] In one possible implementation, Figure 1 or Figure 3 As shown, in the first driving group S11, the first driving circuit T is electrically connected to the first data line D1, and the third driving circuit T is electrically connected to the second data line D2; in the second driving group S21, the first driving circuit T is electrically connected to the second data line D2, and the third driving circuit T is electrically connected to the first data line D1.

[0052] In one possible implementation, Figures 1-8 As shown, the first driving rows S1 and the second driving rows S2 are alternately arranged in sequence along the first direction C1.

[0053] In one possible implementation, the first data line D1 and the second data line D2 may be located on either side of the drive circuit T, respectively. Specifically, the orthographic projection of the first data line D1 on the substrate may overlap with the orthographic projection of the drive circuit T to which it is electrically connected, and the orthographic projection of the second data line D2 on the substrate may overlap with the orthographic projection of the drive circuit T to which it is electrically connected. Specifically, the first data line D1 and the second data line D2 may extend along the second direction C2 and be arranged sequentially along the first direction C1, with the maximum spacing between the first data line D1 and the second data line D2 in the first direction C1 being less than the maximum width of the area in which the electrically connected drive circuit T is distributed in the first direction C1.

[0054] In one possible implementation, the first data line D1 is electrically connected to a first node (not shown) of the driving circuit T, and the second data line D2 is electrically connected to a second node (not shown) of the driving circuit T. The first node and the second node are different locations of the driving circuit T. It is understandable that the structures of the driving circuits T can be the same, and each driving circuit T can have a first node and a second node. However, for each specific driving circuit T, it is electrically connected to a corresponding data line through a specific node.

[0055] In one possible embodiment, combining Figures 1-8As shown, in the first driving group S11, the light-emitting devices F electrically connected to the second and fourth driving circuits T emit green light (i.e., the green light-emitting devices G1 / G2 emitting green light), the light-emitting device F electrically connected to the first driving circuit T emits blue light (i.e., the blue light-emitting device B emitting blue light), and the light-emitting device F electrically connected to the third driving circuit T emits red light (i.e., the red light-emitting device R emitting red light); in the second driving group S21, the light-emitting devices F electrically connected to the second and fourth driving circuits T emit green light (i.e., the green light-emitting devices G1 / G2 emitting green light), the light-emitting device F electrically connected to the first driving circuit T emits red light (i.e., the red light-emitting device R emitting red light), and the light-emitting device F electrically connected to the third driving circuit T emits blue light (i.e., the blue light-emitting device B emitting blue light).

[0056] In one possible embodiment, combining Figure 2 As shown, a line connecting the anode center O12 of the light emitting device F electrically connected to the second driving circuit T in the first driving group S11 and the anode center O22 of the light emitting device F electrically connected to the second driving circuit T in the second driving group S21 is parallel to the first direction C1.

[0057] In one possible embodiment, combining Figure 2 As shown, a straight line k2 passing through the center O11 of the anode of the light-emitting device electrically connected to the first drive circuit T in the first drive group S11 and parallel to the first direction C1 is located between the anode M21 of the light-emitting device electrically connected to the first drive circuit T and the anode M22 of the light-emitting device electrically connected to the second drive circuit T in the second drive group S21; a straight line k3 passing through the center of the anode O13 of the light-emitting device electrically connected to the third drive circuit T in the first drive group S11 and parallel to the first direction C1 is located between the anode M22 of the light-emitting device electrically connected to the second drive circuit T and the anode M23 of the light-emitting device electrically connected to the third drive circuit T in the second drive group S21.

[0058] In one possible embodiment, combining Figure 1 As shown, the first driving circuit T of the first driving group S11 and the first driving circuit T of the second driving group S21 are located in the same column, the second driving circuit T of the first driving group S11 and the second driving circuit T of the second driving group S21 are located in the same column, the third driving circuit T of the first driving group S11 and the third driving circuit T of the second driving group S21 are located in the same column, and the fourth driving circuit T of the first driving group S11 and the fourth driving circuit T of the second driving group S21 are located in the same column.

[0059] Based on the same inventive concept, an embodiment of the present invention further provides a display device, including the display panel provided by the embodiment of the present invention.

[0060] In the embodiment of the present invention, in the first driving group S11, the light emitting devices F electrically connected to the second and fourth driving circuits T have the same light emitting color, and one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. This allows the driving circuits T corresponding to the light emitting devices F of the same light emitting color in the first driving row S1 to be alternately connected to the first data line D1 and the second data line D2, that is, the A-type light emitting units and the B-type light emitting units are alternately distributed, as shown in FIG. Figure 2 As shown by the first horizontal solid line in the figure; in the second driving group S21, the light emitting colors of the light emitting devices F electrically connected to the second and fourth driving circuits T parallel to the second direction C2 are the same as the light emitting colors of the light emitting devices F electrically connected to the second driving circuit T in the first driving group S11. In the second driving group S21, one of the second and fourth driving circuits T is electrically connected to the first data line D1, and the other is electrically connected to the second data line D2. This allows the driving circuits T corresponding to the light emitting devices F of the same light emitting color in the second driving row S2 to be alternately electrically connected to the first data line D1 and the second data line S2, that is, the A-type light emitting units and the B-type light emitting units are alternately distributed, as shown in FIG. Figure 2 As shown by the second horizontal solid line in the figure, when the display panel displays a monochrome image (for example, a green display image), the brightness of each light-emitting unit row is uniform. If the light-emitting devices of the same light-emitting color in the same drive circuit row are all electrically connected to the same data line, and different drive circuit rows are connected to different data lines (for example, the first drive row is electrically connected to the first data line, and the second drive row is electrically connected to the second data line), the parasitic capacitance generated when different drive circuits are connected to different data lines will be different, and the electrical signals supplied to the light-emitting devices will be different, resulting in different luminous brightness of the light-emitting device rows, and thus when displaying a monochrome image, there will be an undesirable problem of alternating distribution of bright horizontal lines and dark horizontal lines; and the second drive circuit T in the second drive group S21 is electrically connected to a different data line than the second drive circuit T in the first drive group S11. In each column of light-emitting devices of the same light-emitting color, the A-type light-emitting units and the B-type light-emitting units are alternately arranged, as shown in FIG. Figure 2 As shown by the vertical solid line, when the display panel displays a monochrome image, the brightness of each light-emitting unit column can be made uniform, thereby improving the problem of alternating distribution of bright vertical lines and dark vertical lines when the display panel displays a monochrome image.
