OLED display devices are driven by pixel driving circuits, but in the use of OLED display devices, it is found that the impedance of some signal lines is large, which easily leads to large signal delays, which in turn leads to problems such as insufficient pixel charging or mischarging, resulting in poor display. In order to reduce the impedance of the signal line, some signal lines will adopt a double-layer design, that is, two parts of the signal line are formed by two film layers to reduce the impedance of the signal line. However, in actual use, it is found that since the edge of the signal line is relatively thin, after static electricity accumulates on the signal line, it is easy to cause tip discharge between the edge of the signal line and the active layer, and then turn on the active layer and the signal line, so that the transistor cannot be turned off, and bright spots appear on the display panel, resulting in abnormal display.

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0032] In order to illustrate the principle of the technical problem of the embodiment of the present application, the embodiment of the present application provides a comparative display device. It can be understood that the comparative display device cannot be used as the prior art of the embodiment of the present application. Specifically, the comparative display device includes a plurality of sub-pixel units, each sub-pixel unit includes a pixel driving circuit and a light-emitting device, the pixel driving circuit includes a light-emitting control line and a reset control line, the light-emitting control line is connected to the light-emitting control transistor, and the reset control line is connected to the reset transistor. In order to reduce the impedance of the light-emitting control line and the reset control line, the light-emitting control line and the reset control line are double-layered.
[0033] like Figure 1 As shown, the comparative display device includes a substrate 111, a semiconductor film layer 112, a first insulating film layer 113, a first gate film layer 114, a second insulating film layer 115 and a first source-drain film layer 116. The light-emitting control line includes a first light-emitting control line arranged in the first gate film layer 114 and a second light-emitting control line located in the first source-drain film layer 116, and the reset control line includes a first reset control line arranged in the first gate film layer 114 and a second reset control line located in the first source-drain film layer 116. Since the light-emitting control line is a double-layer line, the first light-emitting control line and the second light-emitting control line are both long lines, static electricity 117 is easy to accumulate on the light-emitting control line, and the second light-emitting control line is staggered with the first light-emitting control line, the capacitance between the second light-emitting control line and the semiconductor film layer 112 will be relatively large, further increasing the capacitance between the light-emitting control line and the semiconductor film layer 112. The first light-emitting control line is relatively close to the semiconductor film layer 112, and the edge of the first light-emitting control line is relatively thin. The first light-emitting control line is prone to tip discharge with the semiconductor film layer 112, resulting in electrostatic damage, causing the light-emitting control line to be turned on with the active pattern of the light-emitting transistor. The light-emitting control line controls the light-emitting transistor, which causes the light-emitting transistor to be turned on all the time, so that the sub-pixel unit is always lit, resulting in bright spots, resulting in poor display. Similarly, the first reset control line and the second reset control line are long lines, and static electricity is easily accumulated in the reset control line. The first reset control line is relatively close to the semiconductor film layer 112, and the edge of the first reset control line is relatively thin. The first reset control line is prone to tip discharge with the semiconductor film layer 112, resulting in electrostatic damage, causing the reset control line to be turned on with the active pattern of the reset transistor. The reset control line controls the reset transistor, which causes the reset transistor to be turned on all the time, and also causes abnormal display of the sub-pixel unit. Therefore, the existing display device has a technical problem of tip discharge between the edge of the signal line and the active layer, resulting in abnormal display.
[0034] In view of the above technical problems, the embodiments of the present application provide a display panel and a display device to solve the above technical problems.

[0039] Specifically, the light-emitting control line EM and the light-emitting adapter line SL4 are arranged at different layers; the reset adapter line SL3 and the reset control line Reset-A are arranged at different layers.
[0040] In some embodiments, Figures 2 to 17 As shown, the display panel 2 includes a plurality of pixel units 240, each of which includes a plurality of sub-pixel units (e.g., a first sub-pixel unit 240a, a second sub-pixel unit 240b, and a third sub-pixel unit 240c), and the light-emitting adapter line SL4 includes a plurality of light-emitting connecting lines EM-L, and the break 311 is provided between two adjacent light-emitting connecting lines EM-L, and each of the light-emitting connecting lines EM-L is provided corresponding to a sub-pixel unit. By providing each light-emitting connecting line corresponding to a sub-pixel unit, each light-emitting connecting line can drive each transistor, so that each sub-pixel unit works normally.

[0041] In some embodiments, Figures 2 to 17As shown, the display panel 2 includes a plurality of pixel units 240, each of the pixel units 240 includes a plurality of sub-pixel units (e.g., a first sub-pixel unit 240a, a second sub-pixel unit 240b, and a third sub-pixel unit 240c), and the reset adapter line SL4 includes a plurality of reset connection lines RL, and there is a break between two adjacent reset connection lines RL, and each reset connection line RL is set corresponding to one of the sub-pixel units.

[0042] The above embodiment is described by taking the example of a break being set between two sub-pixel units, but the embodiments of the present application are not limited to this. The break can be set within a sub-pixel unit so that the break avoids the active pattern of each transistor, that is, the break does not overlap with the projection of the active pattern of each transistor on the substrate.
[0043] In some embodiments, Figures 2 to 17 As shown, the display panel 2 includes a plurality of pixel units 240, each of which includes a plurality of sub-pixel units (e.g., a first sub-pixel unit 240a, a second sub-pixel unit 240b, and a third sub-pixel unit 240c), the light-emitting adapter SL4 includes a plurality of light-emitting connecting lines EM-L, a break 311 is provided between two adjacent light-emitting connecting lines EM-L, and each light-emitting connecting line EM-L is provided corresponding to one sub-pixel unit; the reset adapter SL4 includes a plurality of reset connecting lines RL, a break is provided between two adjacent reset connecting lines RL, and each reset connecting line RL is provided corresponding to one sub-pixel unit.

At the same time, the light-emitting adapter is divided into a plurality of light-emitting connecting lines, and the reset adapter is divided into a plurality of reset connecting lines, so as to further disperse static electricity, avoid static electricity accumulation, reduce the risk of static electricity explosion caused by tip discharge, and improve the yield of the display panel. Specifically, each light-emitting connection line is connected to a light-emitting control line, and each reset connection line is connected to a reset control line.
[0044] In some embodiments, Figures 2 to 17As shown, the driving circuit layer 22 includes a first gate layer 224 and a first source-drain layer 228, the first gate layer 224 is arranged between the substrate 21 and the first source-drain layer 228, the first gate layer 224 includes the light-emitting connection line EM-L and the reset connection line RL, and the first source-drain layer 228 includes the light-emitting control line EM and the reset control line Reset-A. By arranging the light-emitting connection line and the reset connection line in the first gate layer, the light-emitting control line and the reset control line in the first source-drain layer, and the light-emitting connection line is connected to the light-emitting control line, and the reset connection line is connected to the reset control line, the impedance of the light-emitting control line and the reset control line can be reduced, and multiple light-emitting connection lines connected to the same light-emitting control line are disconnected, and multiple reset connection lines connected to the same reset control line are disconnected, which can avoid static electricity accumulation, reduce the risk of static electricity explosion caused by tip discharge, and improve the yield of the display panel.
[0045] like Figures 2 to 17 As shown, an embodiment of the present application provides a display panel, the display panel 2 includes a plurality of pixel units 240, each of the pixel units 240 includes a plurality of sub-pixel units (for example, a first sub-pixel unit 240a, a second sub-pixel unit 240b and a third sub-pixel unit 240c), the display panel 2 includes a substrate 21 and a driving circuit layer 22, the driving circuit layer 22 is arranged on one side of the substrate 21, the driving circuit layer 22 includes a first gate layer 224 and a first source-drain layer 228, the first gate layer 224 is arranged between the substrate 21 and the first source-drain layer 228, the first gate layer 224 includes a plurality of light-emitting connection lines EM-L and a plurality of reset connection lines RL, the first source-drain layer 228 includes a light-emitting control line EM and a reset control line Reset-A, the light-emitting connection line EM-L is connected to the light-emitting control line EM, and the reset connection line RL is connected to the reset control line Reset-A;
[0046] In two adjacent sub-pixel units (eg, the first sub-pixel unit 240a and the second sub-pixel unit 240b), two adjacent light-emitting connection lines EM-L are disconnected, and / or two adjacent reset connection lines RL are disconnected.
[0047] An embodiment of the present application provides a display panel, which includes a first gate layer 224 including a plurality of light-emitting connection lines EM-L and a plurality of reset connection lines RL, and a first source-drain layer 228 including a light-emitting control line EM and a reset control line Reset-A. The light-emitting connection line EM-L is connected to the light-emitting control line EM, and the reset connection line RL is connected to the reset control line Reset-A. In two adjacent sub-pixel units, two adjacent light-emitting connection lines EM-L are disconnected, and / or two adjacent reset connection lines RL are disconnected, so that the impedance of the light-emitting control line and the reset control line is small, and static electricity is dispersed on the plurality of light-emitting connection lines; and / or static electricity is dispersed on the plurality of reset connection lines, so as to avoid static electricity accumulation, reduce the risk of static electricity injury caused by tip discharge, and improve the yield of the display panel.
[0048] Specifically, there is a slope at the edges of the light-emitting connection line and the reset connection line.
[0049] Specifically, in the first direction, in two adjacent sub-pixel units, two adjacent light-emitting connection lines are disconnected, and / or two adjacent reset connection lines are disconnected.
[0050] Specifically, it can be understood that in the pixel driving circuit, each transistor has a gate, a first electrode, and a second electrode. However, in the actual preparation process, in order to reduce the space occupied by the transistor, some transistor electrodes are not separately set, but the electrodes and signal lines of each transistor are directly connected. For example, in the pixel driving circuit, the first electrode of the driving transistor T1 and the second electrode of the switching transistor T2 are connected to the first node A. When preparing the driving transistor and the switching transistor, there is no need to separately set the first electrode of the driving transistor and the second electrode of the switching transistor. The active pattern of the driving transistor is directly connected to the active pattern of the switching transistor. The connection between the active pattern of the driving transistor and the active pattern of the switching transistor can be regarded as the first node A, thereby reducing the electrodes of the transistor and reducing the space occupied by the transistor. In another example, the first electrode of the compensation transistor is connected to the second electrode of the initialization transistor, but in actual design, there is no need to separately set the first electrode of the compensation transistor and the second electrode of the initialization transistor. The active pattern of the compensation transistor and the active pattern of the initialization transistor are directly connected together. The connection between the active pattern of the compensation transistor and the active pattern of the initialization transistor can be regarded as a point connected to the Q point, or as the Q point, thereby reducing the electrodes of the transistor and reducing the occupied space of the transistor. Similarly, other structures not marked in the film layer diagram also adopt the above design, which can be referred to the above description and will not be repeated in the following embodiments.
[0051] Specifically, in the actual preparation process, in order to reduce the space occupied by the transistor, another way is to make the electrodes of multiple transistors share, or the electrodes of the transistors and the signal lines share the same structure, for example, the gate of the driving transistor is connected to one plate of the storage capacitor, and there is no need to separately set the gate of the driving transistor and one plate of the storage capacitor, and one structure can be used as the gate of the driving transistor and one plate of the storage capacitor. Similarly, for other cases where the same structure is used as the electrodes and / or signal lines of multiple transistors, please refer to the above description, and no further description will be given in the following embodiments.
[0052] Specifically, the display panel includes a plurality of repeating units, and one repeating unit may include a pixel unit, such as the attached pixel unit in the embodiment of the present application. Figure 6 The pixel unit shown is, or a pixel unit in which the reset connection line is electrically connected to the first electrode of the initialization transistor. A repeating unit may also include two pixel units, the difference between the two pixel units is that the reset connection line in one pixel unit is electrically connected to the first electrode of the initialization transistor, and the first electrode of the initialization transistor is connected to the initialization signal line, thereby reducing the voltage drop of the initialization signal line, and the reset connection line in the other pixel unit is electrically connected to the reset signal line, thereby reducing the voltage drop of the reset signal line, and for other parts, the two pixel units may be the same. The following embodiment is described by taking a repeating unit including a pixel unit as an example.
[0053] Specifically, the display panel may include multiple pixel units 240, each pixel unit 240 may include multiple sub-pixel units, the multiple sub-pixel units may include a first sub-pixel unit 240a, a second sub-pixel unit 240b and a third sub-pixel unit 240c, the first sub-pixel unit 240a, the second sub-pixel unit 240b and the third sub-pixel unit 240c all include a pixel driving circuit 220 and a light-emitting device LED, the design of the light-emitting devices of the first sub-pixel unit 240a, the second sub-pixel unit 240b and the third sub-pixel unit 240c may be different, specifically, the light-emitting colors of the light-emitting devices of the first sub-pixel unit 240a, the second sub-pixel unit 240b and the third sub-pixel unit 240c may be different, and / or the areas of the light-emitting devices may be different, and / or the thicknesses of the light-emitting devices may be different.
[0054] Specifically, the light-emitting colors of the first sub-pixel unit, the second sub-pixel unit, and the third sub-pixel unit may be red, green, and blue, respectively, but the embodiments of the present application are not limited thereto. For example, the light-emitting colors of the first sub-pixel unit, the second sub-pixel unit, and the third sub-pixel unit may be red, blue, and green, respectively, or the light-emitting colors of the first sub-pixel unit, the second sub-pixel unit, and the third sub-pixel unit may be blue, green, and red, respectively.
[0055] Specifically, in the embodiments of the present application, it should be noted that, except for the differences explicitly described, the design of all pixel units can refer to the design of the pixel unit provided in the embodiments of the present application. Similarly, the design of all pixel driving circuits can refer to the design of the pixel driving circuit in the embodiments of the present application. For example, the difference between two pixel driving circuits is that the high potential power line of one pixel driving circuit is different from the high potential power line in the other pixel driving circuit, while the other designs of the two pixel driving circuits are the same. In describing the design of the pixel driving circuit, it can be considered that except for the difference in the high potential power line, the other designs of the two pixel driving circuits are the same. Similarly, the differences and the same designs of the pixel units can be determined, and they will not be repeated in the following embodiments.

[0062] Specifically, the light emitting functional layer 24 includes a light emitting device LED, and the pixel electrode layer 241 in the light emitting functional layer 24 includes an anode ANO of the light emitting device LED.
[0063] Specifically, since the embodiments of the present application describe the display panel from the perspective of the circuit, film layer structure, and design of each film layer of the display panel, some structures may belong to both one structure and another structure.

[0065] Specifically, compared to the comparative display device, the first light-emitting control line is a long line, and static electricity will accumulate on the first light-emitting control line. In addition, since there is a slope at the edge of the first light-emitting control line and the thickness of the edge is relatively small, it is easy for the slope of the first light-emitting control line to have tip discharge with the semiconductor film layer.

Static electricity will accumulate on the first light-emitting control line and the first reset control line. Moreover, since there will be a slope at the edges of the first light-emitting control line and the first reset control line, and the thickness of the edge is relatively small, it is easy for the first light-emitting control line and the first reset control line to have a tip discharge with the semiconductor film layer at the slope. In the embodiment of the present application, by disconnecting two adjacent light-emitting connecting lines and two adjacent reset connecting lines, the static electricity can be dispersed to multiple light-emitting connecting lines and multiple reset connecting lines for release, thereby avoiding the problem of static electricity accumulation causing static electricity breakdown between the light-emitting connecting line and the active pattern, and avoiding the problem of static electricity accumulation causing static electricity breakdown between the reset connecting line and the active pattern, thereby reducing the risk of tip discharge between the light-emitting connecting line and the reset connecting line and the active layer, and improving the yield of the display panel.

By making the projection of the light-emitting connecting line EM-L on the substrate 21 overlap with the projection of the light-emitting control line EM on the substrate 21, the width of the light-emitting connecting line EM-L in the second direction Y is greater than or equal to the width of the light-emitting control line EM in the second direction Y. In the overlapping area between the two, the projection of the light-emitting control line EM on the substrate is located within the projection of the light-emitting connecting line EM-L on the substrate, so that the light-emitting connecting line EM-L can block the light-emitting control line, avoiding the formation of capacitance between the light-emitting control line EM-L and the active pattern, reducing the capacitance between the light-emitting control line and the active pattern, reducing the risk of tip discharge between the light-emitting connecting line and the active layer, and improving the yield of the display panel.

By making the projection of the reset connection line RL on the substrate 21 overlap with the projection of the reset control line Reset-Q on the substrate 21, the width of the reset connection line RL in the second direction Y is greater than or equal to the width of the reset control line Reset-Q in the second direction Y. In the overlapping area between the two, the projection of the reset control line Reset-Q on the substrate 21 is located within the projection of the reset connection line RL on the substrate 21, so that the reset connection line RL can block the reset control line Reset-Q, avoiding the formation of capacitance between the reset control line Reset-Q and the active pattern, reducing the capacitance between the light-emitting control line and the active pattern, reducing the risk of tip discharge between the light-emitting connection line and the active layer, and improving the yield of the display panel.
[0074] Specifically, compared with the first reset control line and the second reset control line in the comparative display device, the first reset control line and the second reset control line will form coupling capacitance with the active pattern respectively, which makes it easy for the first reset control line to have tip discharge with the active pattern, resulting in electrostatic damage. In the embodiment of the present application, by making the width of the reset connection line in the second direction greater than or equal to the width of the reset control line in the second direction, in the overlapping area of the two, the projection of the reset control line Reset-Q on the substrate 21 is located within the projection of the reset connection line RL on the substrate 21, and the reset connection line can cover the reset control line, thereby reducing or even eliminating the coupling capacitance between the reset control line and the active pattern, thereby reducing the risk of tip discharge between the reset connection line and the active pattern, and improving the yield of the display panel.
[0075] Specifically, in the arrangement area corresponding to the active pattern, the projection of the reset control line on the substrate is located within the projection of the reset connection line on the substrate.
[0076] Specifically, Figure 1 , Fig.17 As shown, it can be seen that the embodiment of the present application reduces or even eliminates the coupling capacitance between the light emitting control line and the active pattern by making the light emitting connecting line cover the light emitting control line in the overlapping area between the light emitting connecting line and the light emitting control line, and by making the reset connecting line cover the reset control line in the overlapping area between the reset connecting line and the reset control line, thereby reducing or even eliminating the coupling capacitance between the reset control line and the active pattern.

By making the light emitting control line pass through the first via hole to be connected to the light emitting connection line, and the light emitting control line is symmetrically arranged with respect to the first via hole, the light emitting connection line can have a better shielding effect on the light emitting control line, avoid the light emitting control line and the active pattern being directly arranged opposite to each other to form a coupling capacitor, reduce the coupling capacitor between the light emitting control line and the active pattern, reduce the risk of tip discharge between the light emitting connection line and the active pattern, and improve the yield of the display panel.
[0078] Specifically, the light-emitting connecting wires are symmetrically arranged about the first via hole.
[0079] Specifically, compared to the comparative display device in which the connection between the first light-emitting control line and the second light-emitting control line is arranged near the lower side of the first light-emitting control line, the embodiment of the present application arranges the light-emitting control line symmetrically about the first via hole, which can reduce the risk of tip discharge between the light-emitting connecting line and the active pattern and improve the yield of the display panel.
[0080] Specifically, the first via hole 301 penetrates the interlayer insulating layer 227 and the second gate insulating layer 225 .

By arranging the reset signal line in the first source-drain layer, and the second via hole is arranged corresponding to the active pattern of the reset transistor and the reset signal line, the part of the reset signal line located in the active layer can be removed, so as to avoid occupying the space of the active layer and improve the aperture ratio.
[0083] Specifically, compared to the comparative display device, which uses a semiconductor film layer and a first source-drain film layer to form two parts of the reset signal line respectively, the embodiment of the present application takes into account that the semiconductor film layer has little effect on the impedance of the reset signal line, and removes the part of the reset signal line located in the active layer, so that the reset signal line adopts a single-layer design, avoids occupying the space of the active layer, and avoids the reduction of yield due to complex process. By setting the second via hole corresponding to the active pattern of the reset transistor and the reset signal line, the reset signal line can be directly connected to the active pattern of the reset transistor through the second via hole, without adding a transfer line, reducing process steps and reducing occupied space.
[0084] Specifically, the second via hole 302 penetrates the interlayer insulating layer 227 , the second gate insulating layer 225 , and the first gate insulating layer 223 .

By setting the third via hole corresponding to the active pattern of the initialization transistor and the initialization signal line, the initialization signal line can be directly connected to the active pattern of the initialization transistor through the third via hole, without adding a transfer line, reducing the process steps and reducing the occupied space.
[0088] Specifically, the third via hole 303 penetrates the interlayer insulating layer 227 , the second gate insulating layer 225 and the first gate insulating layer 223 .

By making the projection of the light-emitting connection line EM-L on the substrate 21 and the projection of at least part of the data line Data on the substrate 21 have a distance, each light-emitting connection line EM-L can be disconnected, the coupling capacitance between each light-emitting control line EM and the data line Data is small, and the total capacitance of at least part of the data line is reduced, which can prevent crosstalk caused by insufficient pixel charging time or even charging error, improve display uniformity, and improve display effect.
[0091] Specifically, compared to the comparative display device, in which the first light-emitting control wiring and the second light-emitting control wiring both overlap with the data lines, the embodiment of the present application disconnects a plurality of light-emitting connecting lines, retains portions of the light-emitting connecting lines that serve as gates of the first light-emitting control transistor and the second light-emitting control transistor, and the projections of the light-emitting connecting lines on the substrate do not overlap with at least portions of the data lines, thereby reducing the coupling capacitance between the light-emitting control lines and at least portions of the data lines.

By making a distance exist between the projection of the reset connection line RL on the substrate 21 and the projection of the data line Data on the substrate 21, each reset connection line RL can be disconnected, and the coupling capacitance between each reset control line Reset-A and the data line Data is small, thereby reducing the total capacitance of the data line, preventing crosstalk caused by insufficient pixel charging time or even wrong charging, improving display uniformity, and improving display effect.
[0093] Specifically, compared to the comparative display device, in which both the first reset control line and the second reset control line overlap with the data line, the embodiment of the present application disconnects a plurality of reset connection lines, retains a portion of the reset connection line that serves as the gate of the reset transistor, and a projection of the reset connection line on the substrate does not overlap with the data line, thereby reducing the coupling capacitance between the reset control line and at least the data line.

By making the projection of one end of the first connection portion on the substrate and the projection of one end of the high potential power line on the substrate have a gap, the coupling capacitance between the high potential power line and the initialization control line can be reduced, the display uniformity can be improved, and the display effect can be improved.
[0096] Specifically, it can be seen that the initialization control line is connected to one end of the first connection portion SL2a through the via hole, and there is a gap between the projection of the other end of the first connection portion SL2a on the substrate and the projection of one end of the high potential power line VDD on the substrate.

By making the lower end of the fourth via hole and the lower end of the second high potential power connection line located on the same straight line, the fourth via hole can be far away from the active pattern of the driving transistor, so as to avoid the fourth via hole affecting the electrical properties of the active pattern of the driving transistor, thereby affecting the electrical properties of the driving transistor, and improving the electrical stability of the driving transistor.

[0107] Specifically, it is understandable that since each via hole is filled with a structure and each film layer is stacked, the position of each via hole cannot be seen. It is understandable that the position of each via hole can be determined according to the position of each structure.

Since the luminous efficiency of different light-emitting devices is different, by making the areas of the anode of the first light-emitting device, the anode of the second light-emitting device and the anode of the third light-emitting device different from each other, the volume of the light-emitting device can be set according to the luminous efficiency of each light-emitting device, so that the luminous brightness of each light-emitting device can be consistent, thereby improving the display effect.
[0109] Specifically, it can be understood that the light emitting device LED includes a first light emitting device, a second light emitting device and a third light emitting device, and the anodes of the light emitting devices include an anode of the first light emitting device, an anode of the second light emitting device and an anode of the third light emitting device.

[0118] Specifically, Figure 8 As shown, it can be seen that some structures are marked with multiple marks. This is because the electrode and the signal line share this structure, and the signals transmitted on the structure are the same (without considering the voltage drop problem). For example, the gate T5G of the first light-emitting control transistor T5 and the light-emitting connecting line EM-L identify the same structure. This is because the portion of the light-emitting connecting line EM-L corresponding to the active pattern of the first light-emitting control transistor T5 serves as the gate T5G of the first light-emitting control transistor T5. Similarly, the meaning of other structures marked with multiple marks can be determined.

By setting the repair line in the pixel unit, when an abnormality occurs in the sub-pixel unit or the pixel unit, the connection between the anode of the light-emitting device corresponding to the sub-pixel unit and the pixel driving circuit can be disconnected, and the repair line is directly connected to the anode of the sub-pixel unit to directly drive the sub-pixel unit to avoid dark spots. When the sub-pixel unit or the pixel unit does not have an abnormality, the repair line can be left suspended.
