[0110] The transistors used in the present application can be triodes, thin film transistors or field effect transistors or other devices with the same characteristics. In the embodiments of the present application, in order to distinguish the two electrodes of the transistor except the control electrode, one of the electrodes is called the first electrode and the other is called the second electrode.

[0113] In an exemplary embodiment, reference Figure 1 and Figure 2 As shown, Figure 1 This is the overall picture of the display panel. Figure 2 for Figure 1 An example diagram at C in the figure. In the design of narrow-border display panels, such as display panels on wearable products, multiplexing circuits 100 are often used to reduce the number of data lines 600 on the border, thereby achieving the purpose of reducing the border. The data lines 600 extend from the display area A to the multiplexing circuit 100 in the non-display area B. After passing through the multiplexing circuit 100, the number of the originally large number of data lines 600 is reduced, thereby achieving a smaller border. The data lines 600 are used to transmit data signals. The line segments of the data lines 600 located in the non-display area B after passing through the multiplexing circuit 100 can also be called data transmission lines (such as data transmission lines 112), which are used to transmit data signals. Reference Figure 2 As shown, the multiplexing circuit 100 generally includes a plurality of multiplexing subunits 110, each of the multiplexing subunits 110 is connected to a plurality of the data lines 600, and is used to control the pixel units located in the display area A, and the plurality of data transmission lines connected to the plurality of the multiplexing subunits 110 are interconnected via a first type power supply line 200.
[0114] The multiplexing subunit 110 includes multiple multiplexing control lines 111, a data transmission line 112 and multiple control units (for example, a first control unit 113, a second control unit 114 and a third control unit 115). The multiple data lines 600, the multiple multiplexing control lines 111 and the data transmission line 112 are electrically connected to a multiplexing subunit 110 respectively. The multiple control units and the multiple multiplexing control lines 111 in a multiplexing subunit 110 are arranged between the gate drive output line 310 and the display area A, and the multiple control units are located on the side of the multiple multiplexing control lines 111 close to the display area A and are located in the non-display area B. The data transmission line 112 is electrically connected to the first type power supply line 200 across the multiple multiplexing control lines 111, and one first type power supply line 200 is connected to the multiple data transmission lines 112.
[0115] like Figure 2 As shown, the multiplexing subunit 110 has a plurality of multiplexing control lines 111, wherein the first type of power supply line 200 connects the data transmission lines 112 corresponding to at least two adjacent multiplexing subunits 110. However, since the multiplexing control line 111 is a jump signal line, the first type of power supply line 200 passing over the multiplexing control line 111 may be affected by the jump signal, so it is necessary to minimize the overlap of the first type of power supply line 200 with the multiplexing control line 111. Furthermore, the first type of power supply line 200 is overlapped with the gate drive output line 310 and / or with the first power line 510, thereby preventing the first type of power supply line 200 from being affected by the jump signal.
[0116] The present application provides a display panel, including: a base substrate 10, multiple sub-pixels S, multiple data lines 600, multiple data transmission lines 112, multiple multiplexing circuits 100, multiple gate lines 1010, a gate driving circuit 1000, a gate driving output line 310, multiple first-class power supply lines 200 and a first power supply line 510.

[0118] Based on the above description, the first projection area overlaps with the second projection area, for example, the first projection area is located within the second projection area. Since the gate drive output line 310 and the first power line 510 are both stable signals, the first type of power supply line 200 will not be affected by the jump signal, thereby ensuring the uniformity of the display quality.
[0119] Optional, reference Figure 4 As shown, the extension direction of the first type power supply line 200 coincides with the extension direction of some line segments in the gate drive output line 310, and in the direction perpendicular to the extension direction of the first type power supply line 200, the orthographic projection of the first type power supply line 200 on the base substrate 10 and the orthographic projection of some line segments in the gate drive output line 310 on the base substrate 10 at least partially overlap. It should be noted that the extension direction is Figure 3 or Figure 4 The direction of the gate drive output line 310 and the first type of power supply line 200, that is, the tracks of the two are substantially the same, and the two are substantially parallel. Based on the above description, since the orthographic projection of the first type of power supply line 200 on the base substrate 10 and the orthographic projection of some line segments in the gate drive output line 310 on the base substrate 10 at least partially overlap, when performing layout design, the first type of power supply line 200 can be arranged close to the gate drive output line 310, thereby reserving more space for other routing lines arranged on the first power line 510.
[0120] For further reference, Figure 6 As shown, the orthographic projection of the first type power supply line 200 on the base substrate 10 is located within the orthographic projection of the gate drive output line 310. The above statement means that along the direction perpendicular to the extension direction of the first type power supply line 200, the ratio of the width of the first type power supply line 200 to the width of the partial line segment of the gate drive output line 310 is less than or equal to 1.
[0121] Based on the above settings, the orthographic projection of the first type of power supply line 200 on the base substrate 10 is completely located within the orthographic projection of the gate drive output line 310. Since the gate drive output line 310 is a stable signal, the first type of power supply line 200 will not be affected by the jump signal, thereby ensuring the uniformity of the display quality.
[0122] Continue to refer Figure 6As shown, along the direction perpendicular to the extension direction of the first type power supply line 200, the two opposite sides of the partial line segments in the gate drive output line 310 exceed the two opposite sides of the corresponding first type power supply line 200. In this way, the orthographic projection of the first type power supply line 200 on the base substrate 10 is completely located within the orthographic projection of the partial line segments in the gate drive output line 310 on the base substrate 10, which can prevent interference from the jump signal to the greatest extent.
[0123] refer to Figure 5 As shown, the orthographic projection of the first type power supply line 200 on the base substrate 10 coincides with the orthographic projection of a portion of the gate driving output line 310 on the base substrate 10 .
[0124] That is, the first type power supply line 200 is arranged above the gate driving output line 310 along the thickness direction. Such arrangement can free up more areas of the base substrate 10 for wiring.
[0125] refer to Figure 7 As shown, the orthographic projection of the first type power supply line 200 on the base substrate 10 at least partially overlaps with the orthographic projection of some line segments in the first power supply line 510 on the base substrate 10. Since the orthographic projection of the first type power supply line 200 on the base substrate 10 at least partially overlaps with the orthographic projection of some line segments in the first power supply line 510 on the base substrate 10, during layout design, the first type power supply line 200 can be arranged close to the first power supply line 510, thereby reserving more space for setting other routing lines.
[0126] refer to Figure 8 As shown, the orthographic projection of the first type power supply line 200 on the base substrate 10 is located within the orthographic projection of the first power line 510. That is, the first type power supply line 200 is arranged above the first power line 510 in the thickness direction, and such an arrangement can free up more areas of the base substrate 10 for wiring.
[0127] In one embodiment, reference Figure 3-Figure 7 As shown, the multiple data transmission lines 112 include multiple first data transmission lines 112a and multiple second data transmission lines 112b, and the multiple first data transmission lines 112a and the multiple second data transmission lines 112b are respectively located on both sides of the multiple first-type power supply lines 200, and each second data transmission line 112b is connected to at least two first data transmission lines 112a through one first-type power supply line 200, for example, one first-type power supply line 200 is connected to 2 or 3 first data transmission lines 112a.
[0128] Based on the above configuration, one second data transmission line 112b corresponds to multiple first data transmission lines 112a, and the first data transmission line 112a is connected to multiple data lines 600 through a multiplexing subunit 110. In this way, multiple data lines 600 can correspond to one first data transmission line 112a, and multiple first data transmission lines 112a correspond to one second data transmission line 112b, and thus the routing of the transmission data signal in the non-display area B can be reduced through this structure, that is, multiple data lines 600 are connected to one multiplexing subunit 110, one multiplexing subunit 110 is connected to one first data transmission line 112a, and the number of one first data transmission line 112a is reduced relative to the number of multiple data lines 600, thereby achieving a narrow frame. Multiple first data transmission lines 112a are connected to one first-type power supply line 200, and one first-type power supply line 200 is connected to one second data transmission line 112b, and the number of one second data transmission line 112b is reduced relative to the number of multiple first data transmission lines 112a, thereby achieving a narrow frame.
[0129] The ratio of the number of the first data transmission lines 112a corresponding to each multiplexing subunit 110 to the number of the plurality of data lines 600 may be 1 / n, where n is an integer greater than or equal to 2, for example, n may be 2, 3, 6, etc. The ratio of the number of the second data transmission lines 112b corresponding to each multiplexing subunit 110 to the number of the plurality of first data transmission lines 112a may be 1 / m, where m is an integer greater than or equal to 2, for example, m may be 2, 3, 4, 5, etc.
[0130] In one embodiment, reference Figure 5 and Fig. 9As shown, the multiplexing circuit 100 at least includes a first multiplexing circuit 410 and a second multiplexing circuit 420, and the first multiplexing circuit 410 and the second multiplexing circuit 420 both include a plurality of the multiplexing subunits 110 of the same number; the plurality of the multiplexing subunits 110 in the first multiplexing circuit 410 are connected through the first type of power supply line 200, and the first type of power supply line 200 connected to the plurality of the multiplexing subunits 110 in the first multiplexing circuit 410 is used as the first line 210; the plurality of the multiplexing subunits 110 in the second multiplexing circuit 420 are connected through the first type of power supply line 200, and the first type of power supply line 200 connected to the plurality of the multiplexing subunits 110 in the second multiplexing circuit 420 is used as the second line 220. The length L1 of the first line is greater than the length L2 of the second line. Furthermore, the resistance of the first line and the resistance of the second line are taken as a first ratio M1, the ratio of the length L1 of the first line and the length L2 of the second line are taken as a second ratio M2, and the ratio of the length L2 of the second line and the length L1 of the first line are taken as a third ratio M3. The first ratio M1 is greater than the third ratio M3, and the first ratio M1 is less than the second ratio M2.
[0131] It should be noted that the reference Figure 5 and Fig. 9As shown, when the first wire 210 and the second wire 220 are made of the same material and the cross-sectional area S of the first wire 210 and the second wire 220 are the same, the cross-sectional area S here is the cross-sectional area along the width direction H. The first ratio M1 should be equal to the second ratio M2. In this embodiment, the first ratio M1 is set to be greater than the third ratio M3, and the first ratio M1 is set to be less than the second ratio M2, which means that the values of the first wire resistance R1 and the second wire resistance R2 become closer. For example: the length L1 of the first wire is set to 2, and the length L2 of the second wire is set to 1, so the corresponding value of the second ratio M2 is 2. The length L1 of the first wire and the length L2 of the second wire can be um or mm, which is not limited here. Under normal circumstances, the first ratio M1 is equal to the second ratio M2, so the value of the first ratio M1 is equal to 2, and the value of the third ratio M3 is equal to 1 / 2. Since the first ratio M1 is set to be less than the second ratio M2 in this embodiment, the value of the second ratio M2 in this embodiment should be less than 2. There are two ways to reduce the value of the second ratio M2: the first is to increase the value of the second line resistor R2; the second is to reduce the value of the first line resistor R1. Both of the above methods can reduce the gap between the first line resistor R1 and the second line resistor R2. However, if the value of the second line resistor R2 is increased too much, or the value of the first line resistor R1 is reduced too little, the gap between the first line resistor R1 and the second line resistor R2 may be larger, for example: the value of the original first line resistor R1 is set to 2, and the value of the original second line resistor R2 is set to 1. If the value of the second line resistor R2 is increased to 5, or the value of the first line resistor R1 is reduced to 0.1, although the first ratio M1 is smaller than the second ratio M2, the gap between the first line resistor R1 and the second line resistor R2 becomes larger. Therefore, the first ratio M1 is set to be greater than the third ratio M3, and the value of the second line resistor R2 increase and the value of the first line resistor R1 reduction can only be within the range of the reduction of the ratio of the two. For example: the value of the original first line resistor R1 is set to 2, and the value of the original second line resistor R2 is set to 1. Increasing the value of the second line resistance R2 to 2, or reducing the value of the first line resistance R1 to 1, can reduce the difference between the first line resistance R1 and the second line resistance R2. Since the difference between the first line resistance R1 and the second line resistance R2 is reduced, the inconsistency in transmission and loading speed between the two lines caused by the difference between the length L1 of the first line and the length L2 of the second line can be compensated, thereby improving the uniformity of image quality.
[0132] The inventor has found through a large number of experiments that when the first ratio M1 is too small or too large, the transmission and loading speeds between the first line 210 and the second line 220 differ greatly, resulting in inconsistent image quality, which in turn leads to a poor user experience. In this embodiment, the first ratio M1 is set to be greater than or equal to 0.8 and less than or equal to 1.2. Within this range, the transmission and loading speeds between the first line 210 and the second line 220 are basically the same, and the image quality is almost the same in visual experience, thereby improving the user experience.
[0133] It should be noted that the formula of resistance is R=ρL / S, where R is resistance, S is cross-sectional area, L is length, and ρ is resistivity. Under the premise that the length L1 of the first line is greater than the length L2 of the second line, in order to make the value of the first ratio M1 greater than or equal to 0.8 and less than or equal to 1.2, on the one hand, the resistivity of the first line 210 can be set to be smaller than the resistivity of the second line 220. On the other hand, the cross-sectional area of the first line 210 can be set to be larger than the cross-sectional area of the second line 220. According to the above formula, it can be known that under the premise that other conditions remain unchanged, setting the resistivity of the first line 210 to be smaller than the resistivity of the second line 220 can increase the resistance of the first line 210, thereby making the value of the first ratio M1 closer to 1, and thus making the transmission and loading speeds between the first line 210 and the second line 220 close. Similarly, according to the above formula, under the premise that other conditions remain unchanged, setting the cross-sectional area of the first line 210 to be larger than the cross-sectional area of the second line 220 can reduce the resistance of the first line 210, thereby making the value of the first ratio M1 closer to 1, and thus making the transmission and loading speeds between the first line 210 and the second line 220 close.
[0134] In order to achieve the above goals, refer to Figure 6 As shown, the orthographic projection of the second line 220 on the base substrate 10 can be set to fall within the orthographic projection of the gate drive output line 310 on the base substrate 10, referring to Fig. 9 As shown, the orthographic projection area of the first line 210 on the base substrate 10 is set to be larger than the orthographic projection area of a partial line segment of the gate driving output line 310 on the base substrate 10 .
[0135] Through the above settings, when the thickness of the first line 210 and the second line 220 are the same, it can be known that the cross-sectional area of the first line 210 is larger than the cross-sectional area of the second line 220. According to the formula R=ρL / S, the resistance R2 of the second line becomes larger than the resistance of the first line 210, so that the value of the first ratio M1 is closer to 1, and the transmission and loading speeds between the first line 210 and the second line 220 are close.
[0136] refer to Figure 1 and Fig. 9 As shown, the gate driving circuit 1000 includes a plurality of gate driving sub-circuits. Since the length L1 of the first line is greater than the length L2 of the second line, the display panel gate driving sub-circuit can be arranged between two adjacent multiplexing sub-units 110 in the first multiplexing circuit 410. Such an arrangement can make full use of the space between the multiplexing sub-units 110, thereby making the non-display area B of the display panel more compact, thereby making the display panel frame smaller and providing more functions for the display panel.
[0137] In one embodiment, reference Fig.10 , Fig.11 as well as Fig.12 As shown, the second line 220 includes a first portion 221 and a second portion 222; the length of the first line 210 is greater than the length of the second line 220, and the compensation line 700 is arranged between the first portion 221 and the second portion 222, and is connected to the first portion 221 and the second portion 222. Based on this, the transmission and loading speed of the connection between the multiplexing subunits 110 of the first multiplexing circuit 410 is slow, and the transmission and loading speed of the connection between the multiplexing subunits 110 of the second multiplexing circuit 420 is fast. Since the compensation line 700 has a certain resistance, the compensation line 700 can be arranged to slow down the transmission and loading speed of the connection between the multiplexing subunits 110 of the second multiplexing circuit 420, so that the transmission and loading speed of the connection between the multiplexing subunits 110 of the second multiplexing circuit 420 is close. Such a setting can change the transmission and loading speed of the connection between the multiplexing subunits 110 while basically not changing the original design of other parts.
[0138] In addition, refer to Fig.12 As shown, a virtual line 800 may be provided between the first line 210 and the second line 220, and the virtual line 800 is not connected to the first line 210 and the second line 220. The virtual line 800 may avoid the difference in reflectivity caused by the different densities between the first multiplexing circuit 410 and the second multiplexing circuit 420.
[0139] In this embodiment, when the ratio of the total length of the compensation line 700 and the second line 220 to the length of the first line 210 is too small or too large, the transmission and loading speeds between the first line 210 and the second line 220 differ greatly, resulting in inconsistent image quality, which in turn leads to a poor user experience. In this embodiment, the ratio of the total length of the compensation line 700 and the second line 220 to the length of the first line 210 is used as the fourth ratio M4, and the fourth ratio M4 is set to be greater than or equal to 0.8 and less than or equal to 1.2. When other conditions remain unchanged, within this range, the transmission and loading speeds between the first line 210 and the second line 220 are basically the same, and the image quality appears almost the same in visual experience, thereby improving the user experience.
[0140] In one embodiment, reference Figure 1 and Fig.14 As shown, the display panel further includes a plurality of light-emitting control lines 1100, a light-emitting control circuit 1200, a light-emitting control output line 320, a plurality of second-type power supply lines 900, and a second power supply line 520. The plurality of light-emitting control lines 1100 are located in the display area A and are electrically connected to the plurality of sub-pixels S, and the plurality of light-emitting control lines 1100 are configured to transmit light-emitting control signals to the plurality of sub-pixels S; the light-emitting control circuit 1200 is located in the non-display area B and is electrically connected to the plurality of light-emitting control lines 1100; the light-emitting control output line 320 is located in the non-display area B and is connected to the light-emitting control circuit 1200, and the light-emitting control output line 320 is configured to transmit light-emitting control signals to be detected during the display panel preparation stage; the plurality of second-type power supply lines 900 are located in the non-display area B , and a second type power supply line 900 is connected to one end of each of the at least two data transmission lines 112 away from the multiplexing circuit 100; the second power supply line 520 is located on the side of the light emitting control output line 320 away from the display area A; wherein the orthographic projection of the second type power supply line 900 on the base substrate 10 is the third projection area, and the orthographic projection of the light emitting control output line 320, the second power supply line 520 and the areas between the two on the base substrate 10 is the fourth projection area; the third projection area is located within the fourth projection area. It should be noted that, with reference to Figure 1 As shown, the first power line 510 and the second power line 520 are an integrated structure, and the signals of the first power line 510 and the second power line 520 are both negative power signal lines (ie, VSS signal lines).
[0141] refer to Fig.14As shown, the third projection area is the area from the side of the second type of power supply line 900 close to the display area A to the side of the second type of power supply line 900 away from the display area A, and the fourth projection area is the area from one end of the light-emitting control output line 320 close to the display area A to the second power line 520 away from the display area A.
[0142] Based on the above description, the third projection area overlaps with the fourth projection area, for example, the third projection area is located within the fourth projection area. Since the light-emitting control output line 320 and the second power line 520 are both stable signals, the second power line 520 will not be affected by the jump signal, thereby ensuring the uniformity of the display quality.
[0143] refer to Fig.14 and Fig.15 As shown, the extension direction of the second type power supply line 900 coincides with the extension direction of some line segments in the light-emitting control output line 320, and in the direction perpendicular to the extension direction of the second type power supply line 900, the orthographic projection of the second type power supply line 900 on the base substrate 10 and the orthographic projection of some line segments in the light-emitting control output line 320 on the base substrate 10 at least partially overlap. It should be noted that the extension directions coincide, that is, the trajectories of the second type power supply line 900 and the light-emitting control output line 320 are substantially the same, and the two are substantially parallel.
[0144] Based on the above description, since the orthographic projection of the second-type power supply line 900 on the base substrate 10 at least partially overlaps with the orthographic projection of some line segments in the light-emitting control output line 320 on the base substrate 10, when performing layout design, the second-type power supply line 900 can be arranged close to the light-emitting control output line 320, thereby reserving more space for other routing lines arranged on the second power supply line 520.
[0145] refer to Fig.17 As shown, the orthographic projection of the second type power supply line 900 on the base substrate 10 is located within the orthographic projection of the partial line segment of the light emitting control output line 320 on the base substrate 10. The above statement means that along the direction perpendicular to the extension direction of the second type power supply line 900, the ratio of the width of the second type power supply line 900 to the width of the partial line segment of the light emitting control output line 320 is less than or equal to 1.
[0146] Based on the above settings, the orthographic projection of the second type of power supply line 900 on the base substrate 10 is completely located within the orthographic projection of the light-emitting control output line 320. Since the light-emitting control output line 320 is a stable signal, the second type of power supply line 900 will not be affected by the jump signal, thereby ensuring the uniformity of the display quality.
[0147] refer to Fig.17 As shown, along the direction perpendicular to the extension direction of the second type power supply line 900, the two opposite sides of the partial line segments in the light-emitting control output line 320 exceed the two opposite sides of the corresponding second type power supply line 900. In this way, the orthographic projection of the second type power supply line 900 on the base substrate 10 is completely located within the orthographic projection of the partial line segments in the light-emitting control output line 320 on the base substrate 10, which can prevent interference from the jump signal to the greatest extent.
[0148] refer to Fig.16 As shown, the orthographic projection of the second-type power supply line 900 on the base substrate 10 coincides with the orthographic projection of a portion of the line segments in the light-emitting control output line 320 on the base substrate 10 .
[0149] That is, the second type power supply line 900 is arranged above the light emitting control output line 320 along the thickness direction. Such arrangement can free up more areas of the base substrate 10 for wiring.
[0150] refer to Fig.18 As shown, the orthographic projection of the second type power supply line 900 on the base substrate 10 at least partially overlaps with the orthographic projection of some line segments in the second power supply line 520 on the base substrate 10. Since the orthographic projection of the second type power supply line 900 on the base substrate 10 at least partially overlaps with the orthographic projection of some line segments in the second power supply line 520 on the base substrate 10, during layout design, the second type power supply line 900 can be arranged close to the second power supply line 520, thereby reserving more space for other routing lines.
[0151] refer to Fig.19 As shown, the orthographic projection of the second type power supply line 900 on the base substrate 10 is located inside the orthographic projection of the second power supply line 520. That is, the second type power supply line 900 is arranged above the second power supply line 520 along the thickness direction, and such an arrangement can free up more areas of the base substrate for wiring.
[0152] refer to Figure 2-Figure 18 As shown, the multiplexing circuit 100 includes a first control unit 113 and a second control unit 114, the first control unit 113 and the second control unit 114 are respectively connected to one of the data lines 600, and the first control unit 113 and the second control unit 114 share one of the first data transmission lines 112a. It should be noted that the first control unit 113 and the second control unit 114 here can be semiconductor circuits. Under the above setting, one of the first data transmission lines 112a corresponds to two data lines 600, which can reduce the number of the first data transmission lines 112a to half of the number of the data lines 600.
[0153] Furthermore, the multiplexing circuit 100 further includes a third control unit 115, the first control unit 113, the second control unit 114, and the third control unit 115 are respectively connected to one data line 600, and the first control unit 113, the second control unit 114, and the third control unit 115 share one first data transmission line 112a. In this case, one first data transmission line 112a corresponds to three data lines 600, so that the number of first data transmission lines 112a can be reduced to one third of the number of data lines 600.
[0154] The above three data lines 600 can be respectively connected to at least three columns of sub-pixels in the display area A. For example, among the three data lines 600, the first data line 600 is connected to a column of red sub-pixels and blue sub-pixels, and the red sub-pixels and the blue sub-pixels can be arranged alternately in the column direction, the second data line 600 is connected to a column of green sub-pixels, and the third data line 600 is connected to a column of red sub-pixels and blue sub-pixels, and the red sub-pixels and the blue sub-pixels can be arranged alternately in the column direction.
[0155] It should be noted that the sub-pixels here can be white sub-pixels, red sub-pixels, blue sub-pixels, and green sub-pixels, and the multiplexing sub-unit 110 is connected to four data lines 600, and the four data lines 600 are connected to the red sub-pixels, blue sub-pixels, green sub-pixels, and white sub-pixels to control the red sub-pixels, blue sub-pixels, green sub-pixels, and white sub-pixels. In addition, the sub-pixels can also include any one or more of the red sub-pixels, blue sub-pixels, and green sub-pixels, and the multiplexing sub-unit 110 is connected to the data lines 600 that match them, so that one multiplexing sub-unit 110 controls one data line. The arrangement of this embodiment can be more convenient for corresponding connections, and more convenient for adjusting data and control.
[0156] In one embodiment, reference Fig.16 and Fig. 20As shown, the multiplexing circuit 100 at least includes a third multiplexing circuit 430 and a fourth multiplexing circuit 440, and the third multiplexing circuit 430 and the fourth multiplexing circuit 440 both include a plurality of the multiplexing subunits 110 of the same number; the plurality of the multiplexing subunits 110 in the third multiplexing circuit 430 are connected through the second type of power supply line 900, and the second type of power supply line 900 connected to the plurality of the multiplexing subunits 110 in the third multiplexing circuit 430 is used as a third line 910; the plurality of the multiplexing subunits 110 in the fourth multiplexing circuit 440 are connected through the second type of power supply line 900, and the second type of power supply line 900 connected to the plurality of the multiplexing subunits 110 in the fourth multiplexing circuit 430 is used as a fourth line 920. The length L3 of the third line is greater than the length L4 of the fourth line. Furthermore, the ratio of the third line resistance R3 to the fourth line resistance R4 is used as a fifth ratio M5, the ratio of the length L3 of the third line to the length L4 of the fourth line is used as a sixth ratio M6, and the ratio of the length L4 of the fourth line to the length L3 of the third line is used as a seventh ratio M7. The fifth ratio M5 is greater than the seventh ratio M7, and the fifth ratio M5 is less than the sixth ratio M6.
[0157] It should be noted that, when the third line 910 and the fourth line 920 are made of the same material and the cross-sectional area S of the third line 910 and the fourth line 920 are the same, the fifth ratio M5 should be equal to the sixth ratio M6. In this embodiment, the fifth ratio M5 is set to be greater than the seventh ratio M7, and the fifth ratio M5 is set to be less than the sixth ratio M6, which means that the value between the third line resistance R3 and the fourth line resistance R4 becomes closer. For example, the length L3 of the third line is set to 2, and the length L4 of the fourth line is set to 1, so the corresponding value of the sixth ratio M6 is 2. Under normal circumstances, the fifth ratio M5 is equal to the sixth ratio M6, so the value of the fifth ratio M5 is equal to 2, and the value of the seventh ratio M7 is equal to 1 / 2. Since the fifth ratio M5 is set to be less than the sixth ratio M6 in this embodiment, the value of the sixth ratio M6 should be less than 2 in this embodiment. There are two ways to reduce the value of the fifth ratio M5: the first is to increase the value of the fourth line resistor R4; the second is to reduce the value of the third line resistor R3. Both of the above methods can reduce the gap between the third line resistor R3 and the fourth line resistor R4. However, if the value of the fourth line resistor R4 is increased too much, or the value of the third line resistor R3 is reduced too little, the gap between the third line resistor R3 and the fourth line resistor R4 may be larger, for example: the value of the original third line resistor R3 is set to 2, and the value of the original fourth line resistor R4 is set to 1. If the value of the fourth line resistor R4 is increased to 5, or the value of the third line resistor R3 is reduced to 0.1, although the fifth ratio M5 is smaller than the sixth ratio M6, the gap between the third line resistor R3 and the fourth line resistor R4 becomes larger. Therefore, the fifth ratio M5 is set to be greater than the seventh ratio M7, and the value of the fourth line resistor R4 increased and the value of the third line resistor R3 reduced can only be within the range of the reduced ratio of the two. For example: the value of the original third line resistor R3 is set to 2, and the value of the original fourth line resistor R4 is set to 1. Increasing the value of the third line resistor R3 to 2, or reducing the value of the third line resistor R3 to 1, can reduce the difference between the third line resistor R3 and the fourth line resistor R4. Since the difference between the third line resistor R3 and the fourth line resistor R4 is reduced, the inconsistency in transmission and loading speed between the two lines caused by the difference between the length L3 of the third line and the length L4 of the fourth line can be compensated, thereby improving the uniformity of image quality.
[0158] The inventor has found through a large number of experiments that when the fifth ratio M5 is too small or too large, the transmission and loading speeds between the third line 910 and the fourth line 920 differ greatly, resulting in inconsistent image quality, which in turn leads to a poor user experience. In this embodiment, the fifth ratio M5 is set to be greater than or equal to 0.8 and less than or equal to 1.2. Within this range, the transmission and loading speeds between the third line 910 and the fourth line 920 are basically the same, and the image quality is almost the same in visual experience, thereby improving the user experience.
[0159] It should be noted that the formula of resistance is R=ρL / S, where R is resistance, S is cross-sectional area, L is length, and ρ is resistivity. Under the premise that the length L3 of the third line is greater than the length L4 of the fourth line, in order to make the value of the fifth ratio M5 greater than or equal to 0.8 and less than or equal to 1.2, on the one hand, the resistivity of the third line 910 can be set to be smaller than the resistivity of the fourth line 920. On the other hand, the cross-sectional area of the third line 910 can be set to be larger than the cross-sectional area of the fourth line 920. According to the above formula, it can be known that under the premise that other conditions remain unchanged, setting the resistivity of the third line 910 to be smaller than the resistivity of the fourth line 920 can increase the resistance of the third line 910, thereby making the value of the fifth ratio M5 closer to 1, and thus making the transmission and loading speeds between the third line 910 and the fourth line 920 close. Similarly, according to the above formula, under the premise that other conditions remain unchanged, setting the cross-sectional area of the third line 910 to be larger than the cross-sectional area of the fourth line 920 can reduce the resistance of the third line 910, thereby making the value of the fifth ratio M5 closer to 1, thereby making the transmission and loading speeds between the third line 910 and the fourth line 920 close.
[0160] In order to achieve the above goals, refer to Fig.17 As shown, the orthographic projection of the fourth line 920 on the base substrate 10 can be set to fall within the orthographic projection of the light emitting control output line 320 on the base substrate 10, referring to Fig. 20 As shown, the orthographic projection area of the third line 910 on the base substrate 10 is set to be larger than the orthographic projection area of a partial line segment of the light emitting control output line 320 on the base substrate 10 .
[0161] Through the above settings, when the third line 910 and the fourth line 920 have the same thickness, it can be known that the cross-sectional area of the third line 910 is larger than the cross-sectional area of the fourth line 920. According to the formula R=ρL / S, the resistance R4 of the fourth line is larger than the resistance of the third line 910, so that the value of the fifth ratio M5 is closer to 1, thereby making the transmission and loading speeds between the third line 910 and the fourth line 920 close.
[0162] refer to Figure 1 and Fig. 20As shown, the light control circuit 1200 includes a plurality of light control sub-circuits. Since the length L3 of the third line is greater than the length L4 of the fourth line, the light control sub-circuit can be arranged between two adjacent multiplexing sub-units 110 in the third multiplexing circuit 430. Such an arrangement can make full use of the space between the multiplexing sub-units 110, thereby making the non-display area B of the display panel more compact, thereby making the overall frame of the display panel smaller and providing more functions for the display panel.
[0163] In one embodiment, reference Fig.21 , Fig. 22 , Fig.23 as well as Fig.24 As shown, the fourth line 920 includes a third part 921 and a fourth part 922 and is connected to the third part 921 and the fourth part 922; the length of the third line 910 is greater than the length of the fourth line 920, and the compensation line 700 is arranged between the third part 921 and the fourth part 922. Based on this, the transmission and loading speed of the connection between the multiplexing subunits 110 of the third multiplexing circuit 430 is slow, and the transmission and loading speed of the connection between the multiplexing subunits 110 of the fourth multiplexing circuit 440 is fast. Since the compensation line 700 has a certain resistance, the compensation line 700 can be arranged to slow down the transmission and loading speed of the connection between the multiplexing subunits 110 of the fourth multiplexing circuit 440, so that the transmission and loading speed of the connection between the multiplexing subunits 110 of the fourth multiplexing circuit 440 is close. Such a setting can change the transmission and loading speed of the connection between the multiplexing subunits 110 while basically not changing the original design of other parts.
[0164] In addition, reference Fig.23 As shown, a virtual line 800 may be provided between the third line 910 and the fourth line 920, and the virtual line 800 is not connected to the third line 910 and the fourth line 920. The virtual line 800 may avoid the difference in reflectivity caused by the different densities between the third multiplexing circuit 430 and the fourth multiplexing circuit 440.
[0165] In this embodiment, when the ratio of the total length of the compensation line 700 and the fourth line 920 to the length of the third line 910 is too small or too large, the transmission and loading speeds between the third line 910 and the fourth line 920 differ greatly, resulting in inconsistent image quality, which in turn leads to a poor user experience. In this embodiment, the ratio of the total length of the compensation line 700 and the fourth line 920 to the length of the third line 910 is used as the eighth ratio M8, and the eighth ratio M8 is set to be greater than or equal to 0.8, and less than or equal to 1.2. When other conditions remain unchanged, within this range, the transmission and loading speeds between the third line 910 and the fourth line 920 are basically consistent, and the image quality appears almost consistent in visual experience, thereby improving the user experience.

For example, a red light-emitting element includes a red light-emitting layer, a green light-emitting element includes a green light-emitting layer, and a blue light-emitting element includes a blue light-emitting layer. In order to reduce the process difficulty and improve the yield, the hole injection layer and the hole transport layer on one side of the light-emitting layer may use a common layer, and the electron injection layer and the electron transport layer on the other side of the light-emitting layer may use a common layer. In some examples, any one or more layers of the hole injection layer, the hole transport layer, the electron injection layer, and the electron transport layer can be made by a single process (a single evaporation process or a single inkjet printing process), and isolation is achieved by means of a surface step difference of the formed film layer or by surface treatment. For example, any one or more layers of the hole injection layer, the hole transport layer, the electron injection layer, and the electron transport layer corresponding to adjacent sub-pixels may be isolated. In some examples, the organic light-emitting layer can be formed by evaporation using a fine metal mask (FMM, Fine Metal Mask) or an open mask (Open Mask), or by inkjet technology.
