AI Technical Summary
The area of the light-transmitting region in the under-panel imaging area of a conventional OLED display panel is reduced due to signal lines horizontally connecting to pixel circuits, leading to inadequate infrared transmittance.
The design includes a first display area with light-transmitting parts between pixel circuits and a second display area with signal lines connected to multiple pixel circuits, where at least two signal lines share the same control signal, avoiding direct crossing over the light-transmitting area and reducing the area occupied by signal lines.
This configuration increases the light-transmitting area in the first display area, maintaining resolution by reducing the number of pixel circuits and enhancing the light-emitting elements, enabling applications like under-screen fingerprint recognition and camera functionality.

Abstract
Description
Technical Field
[0001] This application relates to the display field, and particularly to a display panel and a display device.
Background Art
[0002] In the Camera Under Panel (CUP) technology of an Organic Light-Emitting Diode (OLED) display panel, since the distribution density of pixel driving circuits in the under-panel imaging area is usually smaller than that in the display area, a part of the signal lines for transmitting control signals in the display area located on both sides of the under-panel imaging area is directly connected horizontally. Without avoiding the under-panel imaging area, this horizontally connected signal line occupies the area of a part of the light-transmitting area in the under-panel imaging area. As a result, there is a technical problem that the area of the light-transmitting area in the under-panel imaging area is reduced, and the infrared transmittance of the under-panel imaging area fails to reach the reference value.

Therefore, the features limited to "first" and "second" can include one or more features, either explicitly or implicitly. In the description of the present application, unless explicitly and specifically limited, "plurality" means two or more, and "at least one" means one, two, or more.
[0011] Referring to FIG. 1, the present application provides a display panel 100, which includes a first display area 300, a second display area 400 located around the first display area 300, and a non-display area 200 located on one side of the second display area 400.
[0012] In some embodiments of the present application, a plurality of signal lines connected to pixel circuits are provided in both the second display area 400 and the first display area 300. However, since a light-transmitting portion 300b is provided in the first display area 300, some signal lines may cross the light-transmitting portion 300b in the first display area 300 and occupy the area of the light-transmitting portion 300b. As a result, the effective light-transmitting area in the light-transmitting portion 300b is reduced, for example, the configuration shown in FIG. 2.
[0013] Referring to FIG. 3, a plurality of first pixel circuits 310 and a plurality of light-transmitting portions 300b located between the plurality of first pixel circuits 310 are provided in the first display area 300, and a plurality of second pixel circuits 410 are provided in the second display area 400. Each of the signal lines is connected to one row of the second pixel circuits 410, and at least two of the signal lines transmitting the same control signal are connected to a plurality of the same first pixel circuits 310.
[0014] By electrically connecting at least two signal lines that transmit the same control signal to a plurality of identical first pixel circuits 310, it is possible to avoid the signal lines directly crossing the first display area 300, reduce the area of the light-transmitting region occupied by the signal lines in the first display area 300, and thus increase the area of the light-transmitting region in the first display area 300.
[0015] Referring to FIG. 3, a plurality of functional sub-parts 300a and a plurality of light-transmitting parts 300b located between the plurality of functional sub-parts 300a may be provided in the first display area 300. Each functional sub-part 300a includes a plurality of first pixel circuits 310 and one sub-signal line group 320. One sub-signal line group 320 is connected to the corresponding plurality of first pixel circuits 310, and each sub-signal line group 320 includes at least one sub-signal line.
[0016] Referring to FIG. 3, a plurality of first main parts 400a may be provided in the second display area 400. Each first main part 400a includes a plurality of second pixel circuits 410 arranged along at least two rows in the first direction X and at least two main signal line groups 420. One main signal line group 420 is connected to the corresponding row of second pixel circuits 410, and each main signal line group 420 includes at least one main signal line. And one functional sub-part 300a corresponds to one first main part 400a.
[0017] For example, in the functional sub-part 300a and the first main part 400a corresponding to the functional sub-part 300a, at least two main signal lines that transmit the same control signal in the first main part 400a are electrically connected to a parallel connection node with one sub-signal line that transmits the same control signal in the functional sub-part 300a. Thereby, it is possible to avoid the main signal lines that transmit the same control signal in the first main part 400a from crossing the functional sub-part 300a, which is equivalent to increasing the area of the light-transmitting region in the functional sub-part 300a.
[0018] Furthermore, since there are multiple main signal lines that transmit different control signals in the signal lines that cross the first display area 300, the present invention can avoid the light-transmitting portion 300b in the first display area 300 by electrically connecting the corresponding main signal line that transmits at least one type of control signal to the corresponding sub-signal line.
[0019] The display panel 100 may include multiple first display areas 300, and the shape of each first display area 300 in plan view is not limited to a circle, rectangle, or rounded rectangle. For example, in the configuration of Figure 1, the display panel 100 may include one first display area 300.
[0020] In the configuration shown in Figure 3, the first display area 300 is provided with multiple first main sections 400a on both sides in the first direction X.
[0021] Furthermore, one first main unit 400a corresponds to one functional sub-unit 300a, and one first main unit 400a has at least two rows of second pixel circuits 410, while one functional sub-unit 300a has only one row of first pixel circuits 310. Therefore, in order to increase the light transmittance of the first display area 300, the present invention reduces the number of rows of first pixel circuits 310 in the first display area 300. For example, in the configuration shown in Figure 3, one first main unit 400a has two rows of second pixel circuits 410, and one functional sub-unit 300a has one row of first pixel circuits 310, meaning that one row of first pixel circuits 310 corresponds to two rows of second pixel circuits 410.
[0022] Furthermore, since the number of rows in the first pixel circuit 310 in the first display area 300 is reduced, the number of light-emitting elements connected to the first pixel circuit 310 is reduced, and consequently the resolution of the first display area 300 is no longer lower than the resolution of the second display area 400. For this reason, the present invention may increase the number of light-emitting elements connected to the first pixel circuit 310 in order to improve the difference in resolution between the first display area 300 and the second display area 400.
[0023] For example, the first display area 300 may include a plurality of first light-emitting elements 330, and the second display area 400 further includes a plurality of second light-emitting elements 430, and one second pixel circuit 410 is electrically connected to one second light-emitting element 430, and one first pixel circuit 310 is electrically connected to two first light-emitting elements 330. In the first display area 300, the resolution of the first display area 300 is increased by electrically connecting one first pixel circuit 310 to two first light-emitting elements 330.
[0024] Furthermore, since one first pixel circuit 310 is electrically connected to two first light-emitting elements 330, the light-emitting elements do not occupy a relatively large area of the light-transmitting portion 300b, and therefore the area of the first light-emitting element 330 in this application is smaller than the area of the second light-emitting element 430.
[0025] Furthermore, in order that the arrangement of the first pixel circuits 310 in the first display area 300 does not occupy a relatively large area of the light-transmitting portion 300b, the multiple first pixel circuits 310 in this application are arranged in the form of pixel cells 340, with two adjacent pixel cells 340 spaced apart, and each first pixel circuit 310 has the same configuration. For example, in the configurations of Figures 11 to 13, one pixel cell 340 may include three clustered first pixel circuits 310, and the six first light-emitting elements 330 connected to each pixel cell 340 may be light-emitting elements with two red emission colors, two green emission colors, and two blue emission colors.
[0026] The plurality of pixel cells 340 in this application may have two arrangement methods. In the first arrangement method, the plurality of pixel cells 340 are arranged in an array along a first direction X and a second direction Y, that is, the plurality of pixel cells 340 are arranged to form rows and columns in the first direction X and the second direction Y, that is, each sub-control line may be connected to one row of first pixel circuits 310. Alternatively, the plurality of pixel cells 340 in this application are arranged along the first direction X to form a plurality of pixel cell rows, and two adjacent rows of pixel cells 340 are offset from each other, that is, each sub-control line may be connected to two offset rows of first pixel circuits 310.
[0027] Furthermore, in order to increase the area of the light-transmitting portion 300b, the area of each first pixel circuit 310 is smaller than the area of each second pixel circuit 410, which corresponds to a further reduction in the area occupied by the first pixel circuit 310 in the first display area 300.
[0028] Referring to Figures 11 to 13, the second display area 400 is provided with a plurality of second pixel circuits 410, and in the first main part 400a, two adjacent second pixel circuits 410 arranged along the first direction X are provided symmetrically with respect to the center line of the two adjacent second pixel circuits 410 as the axis. That is, the present invention provides two adjacent second pixel circuits 410 symmetrically, and ensures that the configuration of the second pixel circuits 410 in the same row is the same, so as not to limit the invention to a compact type.
[0029] Referring to Figures 11 to 13, since one row of first pixel circuits 310 corresponds to two rows of second pixel circuits 410, the present invention may provide the first pixel circuit 310 of this row in a corresponding row between the two rows of second pixel circuits 410. For example, the extension of the boundary line of two adjacent rows of second pixel circuits 410 coincides with the median line parallel to the first direction X in the corresponding first pixel circuit 310, or the value of the difference between this extension and its center is within a predetermined range.
[0030] Although the number of first pixel circuits 310 in the first display area 300 of this application has been reduced, the area occupied by the first pixel circuits 310 has been reduced, so the sum of the second pixel circuits 410 and the first pixel circuits 310 in one row of pixel circuits in this application has not been reduced. For example, in a second display area 400 where no first pixel circuits 310 are provided, the number of second pixel circuits 410 in one row is a0, and in a sub-pixel row where the first pixel circuits 310 are provided, the number of second pixel circuits 410 in this sub-pixel row is a1 and the number of first pixel circuits 310 is a2, then the sum of a1 and a2 in this application is equal to a0.
[0031] Similarly, since two first light-emitting elements 330 can be connected to one first pixel circuit 310 of the present invention, the area of the light-emitting region in the first display region 300 of the present invention is reduced, but the number of light-emitting units per unit area in the first display region 300 is equal to the number of light-emitting units per unit area in the second display region 400.
[0032] The first display area 300 may also correspond to a sensor. The sensor receives light incident from the light-transmitting portion 300b in the first display area 300 and forms a corresponding voltage or current signal, etc. For example, the sensor may include a fingerprint recognition sensor, a camera, a structural light sensor, a time-of-flight sensor, a distance sensor, a light sensor, etc. The sensor collects signals through the light-transmitting portion 300b and enables the display panel 100 to implement solutions such as under-screen fingerprint recognition, under-screen camera, under-screen face recognition, and under-screen distance detection.
[0033] The first light-emitting element 330 and the second light-emitting element 430 of this application may both be organic light-emitting diodes, mini LEDs, micro LEDs, conventional-sized LEDs, or other light sources.
[0034] Furthermore, the angle between the first direction X and the second direction Y in this application is greater than 0 and 90° or less. For example, the first direction X in this application may be the horizontal direction from the non-display area 200 toward the display area, the second direction Y may be the vertical direction, and the angle between the first direction X and the second direction Y may be 90°.
[0035] The technical proposal of this application will be explained below, along with specific examples.
[0036] Referring to Figures 1 and 3, a bonding pad 500 is provided below the second display area 400. The bonding pad 500 may be connected to an external circuit, and the bonding pad 500 transmits signals input from the external circuit to the data wiring, driving the display panel 100 to display the screen. For example, the bonding pad 500 may be bonded to a chip or flip-chip thin film, etc., in order to provide power and drive signals to the display panel 100.
[0037] In this embodiment, both the second pixel circuit 410 and the first pixel circuit 310 may be pixel circuits such as 7T1C, 7T2C, 8T2C, 8T3C, or 8T4C. In the following embodiment, an 8T2C pixel circuit will be described as an example.
[0038] Referring to Figure 4, both the second pixel circuit 410 and the first pixel circuit 310 may include a switching transistor T2, a drive transistor T1, a compensation transistor T3, a first reset transistor T4, a second reset transistor T7, a third reset transistor T8, a first light-emitting transistor T5, a second light-emitting transistor T6, a boost capacitor Cboost, and a storage capacitor Cst. The storage capacitor Cst includes a first pole plate Cst1 and a second pole plate Cst2, and the boost capacitor Cboost includes a third pole plate and a fourth pole plate.
[0039] Referring to Figure 4, the first electrode of switching transistor T2 is connected to the data signal line Data, the second electrode of switching transistor T2 is connected to the first node A1, and the gate of switching transistor T2 receives the switching control signal Pscan1. The first electrode of driving transistor T1 is connected to the first node A1, the second electrode of driving transistor T1 is connected to the second node B1, and the gate of driving transistor T1 is connected to the third node Q1. The first electrode of compensating transistor T3 is connected to the third node Q1, the second electrode of compensating transistor T3 is connected to the second node B1, and the gate of compensating transistor T3 receives the compensation control signal Nscan1. The first electrode of the first reset transistor T4 receives the first reset signal Vi1, the second electrode of the first reset transistor T4 is connected to the third node Q1, and the gate of the first reset transistor T4 receives the first reset control signal Nscan2. The first electrode of the second reset transistor T7 is connected to the second reset signal Vi2, and the second electrode of the second reset transistor T7 is connected to the fourth node, i.e., the anode of the light-emitting element, and the gate of the second reset transistor T7 receives the second reset control signal Pscan2. The first electrode of the third reset transistor T8 receives the third reset signal Vi3, and the second electrode of the third reset transistor T8 is connected to the first node A1, and the gate of the third reset transistor T8 receives the third reset control signal. The first electrode of the first light-emitting transistor T5 is connected to the high-potential line VDD, and the second electrode of the first light-emitting transistor T5 is connected to the first node A1, and the gate of the first light-emitting transistor T5 receives the light-emitting control signal EM. The first electrode of the second light-emitting transistor T6 is connected to the second node B1, and the second electrode of the second light-emitting transistor T6 is connected to the fourth node D1, and the gate of the second light-emitting transistor T6 receives the light-emitting control signal EM. The third electrode plate of the boost capacitor Cboost is connected to the third node Q1, and the fourth electrode plate of the boost capacitor Cboost is connected to the gate of the switching transistor T2. The first electrode plate of the storage capacitor Cst is connected to the third node Q1, and the second electrode plate of the storage capacitor Cst is connected to the high-potential line VDD. The cathode of the light-emitting element is connected to the low-potential line VSS.
[0040] In this embodiment, the high-potential line VDD is used to provide a high-level constant voltage to the second pixel circuit 410 or the first pixel circuit 310, and the low-potential line VSS is used to provide a low-level constant voltage to the second pixel circuit 410 or the first pixel circuit 310.
[0041] In this embodiment, the switching transistor T2, the driving transistor T1, the second reset transistor T7, the third reset transistor T8, the first light-emitting transistor T5, and the second light-emitting transistor T6 may be either P-type or N-type transistors. The compensation transistor T3 and the first reset transistor T4 may be the other of P-type or N-type transistors. This application describes the case where the switching transistor T2, the driving transistor T1, the second reset transistor T7, the third reset transistor T8, the first light-emitting transistor T5, and the second light-emitting transistor T6 are P-type transistors, and the compensation transistor T3 and the first reset transistor T4 are N-type transistors as an example.
[0042] In this embodiment, the capacitance value of the boost capacitor Cboost is smaller than that of the storage capacitor Cst. In this embodiment, the storage capacitor Cst is mainly used to maintain stability regarding the potential of the third node Q1, so the capacitance value of the storage capacitor Cst is relatively large. For example, the capacitance value range of the storage capacitor Cst may be 45fF to 55fF, and the capacitance value range of the boost capacitor Cboost may be 5fF to 15fF.
[0043] In this embodiment, the first electrode may be either the source or the drain, and the second electrode may be the other of the source or the drain.
[0044] Referring to Figures 1 and 3, the non-display area 200 may include two non-display sub-sections 210 located on either side of the second display area 400. Each of the two non-display sub-sections 210 is provided with a gate drive circuit, and the output terminal of the gate drive circuit is connected to at least one of the signal lines.
[0045] In this embodiment, the gate drive circuit may include gate circuits that output different control signals. The type of gate circuit in the non-display area 200 relates to the second pixel circuit 410 or the first pixel circuit 310. For example, the second pixel circuit 410 or the first pixel circuit 310 requires a compensation control signal Nscan1, a first reset control signal Nscan2, a second reset control signal Pscan2, a light emission control signal EM, and a switching control signal Pscan1. Therefore, in the non-display area 200 of this application, it is necessary to install five types of gate circuits that output the above-mentioned control signals.

[0116] Referring to Figures 9 and 10, the first source-drain layer 133 is primarily used to form the source and drain of at least some of the transistors in the second pixel circuit 410 and the first pixel circuit 310.
[0117] Referring to Figures 9 and 10, the second source-drain layer 135 includes a data signal line Data, a high-level line VDD, and a fan-out wiring FIAA. In the configuration of Figure 9, the data signal line Data is provided between two second pixel circuits 410, and the fan-out wiring is provided between two data signal lines Data. In the configuration of Figure 10, the data signal line Data is provided on one side of each first pixel circuit 310, and the high-level line VDD is provided between two adjacent data signal lines Data.
[0118] Referring to Figures 1 and 3, the second display area 400 further includes a second main section 400b. The second main section 400b is provided with a plurality of second pixel circuits 410 arranged along a first direction X in multiple rows, and since the plurality of rows of second pixel circuits 410 in the second main section 400b do not traverse the first display area 300, the five main signal lines in the second main section 400b can extend along the first direction X from one non-display sub-section 210 to the other non-display sub-section 210 of the display panel 100. On the other hand, with respect to the multi-row second pixel circuit 410 in the first main unit 400a, if the main signal lines in the two main signal line groups 420 of the first main unit 400a are arranged in the same way as the five main signal lines in the second main unit 400b in order to install the light-transmitting section 300b in the first display area 300, then there will be one main signal line group 420 in the first main unit 400a that overlaps with the light-transmitting section 300b in the first display area 300. As a result, the area of the light-transmitting section 300b will be reduced, and the proportion of the area of the light-transmitting section 300b in the first display area 300 will decrease.
[0119] Accordingly, the present invention reduces the number of main signal lines crossing the light-transmitting section 300b and, consequently, increases the area ratio of the light-transmitting section 300b in the first display area 300 by having at least one main signal line from one main signal line group 420 of the first main section 400a connected to a main signal line in another main signal line group 420 that transmits the same control signal, and also electrically connected to a sub-signal line in the functional sub-section 300a that transmits the same control signal.
[0120] For example, in a functional sub-unit 300a and a first main unit 400a corresponding to the functional sub-unit 300a, at least two main compensation control lines 421 in the first main unit 400a are electrically connected to one sub-compensation control line 321 in the functional sub-unit 300a at the first parallel connection node M1. And / or, at least two first main reset control lines 422 in the first main unit 400a are electrically connected to one first sub-reset control line 322 in the functional sub-unit 300a at the second parallel connection node M2. And / or, at least two second main reset control lines 423 in the first main unit 400a are electrically connected to one second sub-reset control line 323 in the functional sub-unit 300a at the third parallel connection node M3. And / or, at least two main light emission control lines 424 in the first main section 400a are electrically connected to one sub-light emission control line 324 in the functional sub-section 300a at the fourth parallel connection node M4.
[0121] That is, in the configurations of Figures 3 and 12, one main compensation control line 421 in the first main unit 400a is directly connected to the sub-compensation control line 321 in the corresponding functional sub-unit 300a, and another main compensation control line 421 in the first main unit 400a is connected to the sub-compensation control line 321 of the functional sub-unit 300a at the first parallel connection node M1. And / or, one first main reset control line 422 in the first main unit 400a is directly connected to the first sub-reset control line 322 in the corresponding functional sub-unit 300a, and another first main reset control line 422 in the first main unit 400a is connected to the first sub-reset control line 322 of the functional sub-unit 300a at the second parallel connection node M2. And / or, this corresponds to one second main reset control line 423 in the first main unit 400a being directly connected to the second sub-reset control line 323 in the corresponding functional sub-unit 300a, and another second main reset control line 423 in the first main unit 400a being connected to the second sub-reset control line 323 of the functional sub-unit 300a at the third parallel connection node M3. And / or, this corresponds to one main light emission control line 424 in the first main unit 400a being directly connected to the sub-light emission control line 324 in the corresponding functional sub-unit 300a, and another main light emission control line 424 in the first main unit 400a being connected to the sub-light emission control line 324 of the functional sub-unit 300a at the fourth parallel connection node M4.
[0122] Referring to Figures 3 and 11 to 13, in order to increase the area ratio of the light-transmitting portion 300b in the first display area 300, the two main compensation control lines 421 in the first main section 400a of the present invention are both electrically connected to the sub-compensation control line 321 in the corresponding functional sub-section 300a, the two first main reset control lines 422 in the first main section 400a are both electrically connected to the first sub-reset control line 322 in the corresponding functional sub-section 300a, the two second main reset control lines 423 in the first main section 400a are both electrically connected to the second sub-reset control line 323 in the corresponding functional sub-section 300a, and the two main light emission control lines 424 in the first main section 400a are both electrically connected to the sub-light emission control line 324 in the corresponding functional sub-section 300a.
[0123] Note that the number of stacked film layers in Figures 11 and 13 is the same, and both include the first gate layer 125, the second gate layer 127, and the third gate layer 131. The difference between Figure 11 and Figure 13 is that the enlarged areas shown are different. Figure 12 includes all the metallic conductive layers of the display panel 100 array drive layer.
[0124] Referring to Figures 11 to 13, the plurality of pixel cells 340 include a first pixel cell 340a and a second pixel cell 340b, the first pixel cell 340a is installed adjacent to the first main unit 400a, and the second pixel cell 340b is installed adjacent to the first pixel cell 340a, and both the first pixel cell 340a and the second pixel cell 340b include a plurality of first pixel circuits 310.
[0125] In this embodiment, since the proportion of the unit area of the first light-emitting element 330 in the second display area 400 is larger than the proportion of the unit area of the second light-emitting element 430 in the first display area 300, in order to minimize the display difference in the transition area between the second display area 400 and the first display area 300, the present invention makes the distance between the first main part 400a and the first pixel cell 340a smaller than the distance between the first pixel cell 340a and the second pixel cell 340b.
[0126] In addition, the distance between the first main unit 400a and the first pixel cell 340a is smaller than the distance between the first pixel cell 340a and the second pixel cell 340b, while the connection between the two main signal lines and the one sub-signal line needs to occupy a certain amount of space. Therefore, the first parallel connection node M1 of this application may be located between the first main unit 400a and the first pixel cell 340a, or between the first pixel cell 340a and the second pixel cell 340b, and the second parallel connection node M2 is The third parallel connection node M3 may be located between the first main unit 400a and the first pixel cell 340a, or between the first pixel cell 340a and the second pixel cell 340b, and the fourth parallel connection node M4 may be located between the first main unit 400a and the first pixel cell 340a, or between the first pixel cell 340a and the second pixel cell 340b.
[0127] Referring to Figures 11 to 13, the first parallel connection node M1, the third parallel connection node M3, and the fourth parallel connection node M4 are all located between the first pixel cell 340a and the second pixel cell 340b, while the second parallel connection node M2 is located between the first main unit 400a and the first pixel cell 340a.
[0128] Furthermore, since the first parallel connection node M1, the second parallel connection node M2, the third parallel connection node M3, and the fourth parallel connection node M4 are all located in the first display area 300, multiple extension lines need to be installed in the first display area 300 in order to electrically connect the main signal line to the sub-signal line.
[0129] Referring to Figures 11 to 13, the functional sub-section 300a further includes a first extending segment 351, a second extending segment 352, a third extending segment 353, and a fourth extending segment 354, all located around the first pixel cell 340a. The second extending segment 352 is located between the first main section 400a and the first pixel cell 340a, while the first extending segment 351, the third extending segment 353, and the fourth extending segment 354 extend toward the side away from the first main section 400a.
[0130] In this embodiment, one end of the first extended segment 351 is electrically connected to a main compensation control line 421 in the first main section 400a, and the other end of the first extended segment 351 is electrically connected to a sub-compensation control line 321 in the region where the first parallel connection node M1 is located. One end of the second extended segment 352 is electrically connected to a first main reset control line 422 in the first main section 400a, and the other end of the second extended segment 352 is electrically connected to a first sub-reset control line 322 in the region where the second parallel connection node M2 is located. One end of the third extended segment 353 is electrically connected to a second main reset control line 423 in the first main section 400a, and the other end of the third extended segment 353 is electrically connected to a second sub-reset control line 323 in the region where the third parallel connection node M3 is located. One end of the fourth extended segment 354 is electrically connected to a main light emission control line 424 in the first main section 400a, and the other end of the fourth extended segment 354 is electrically connected to a sub-light emission control line 324 in the region where the fourth parallel connection node M4 is located.
[0131] In this embodiment, both the first extending segment 351 and the main compensation control line 421 of the present application are located in the same metal layer, while the main compensation control line 421 has a first portion located in the second gate layer 127 and a second portion located in the third gate layer 131. Similarly, the present application has a first extending segment 351 located in the second gate layer 127 and a first extending segment 351 located in the third gate layer 131. Furthermore, the two first extending segments 351 in different layers both extend toward the side away from the first main part 400a and at least partially overlap, and together the two first parallel connection nodes M1 are both located between the first pixel cell 340a and the second pixel cell 340b.
[0132] Similarly, the present invention has a second extending segment 352 located in the second gate layer 127 and a second extending segment 352 located in the third gate layer 131. Furthermore, the second extending segment 352 located in the second gate layer 127 is located between the first main section 400a and the first pixel cell 340a, while the second extending segment 352 located in the third gate layer 131 extends toward the side away from the first main section 400a and is located around the first pixel cell 340a, that is, the two second parallel connection nodes M2 are one located between the first main section 400a and the first pixel cell 340a and the other located between the first pixel cell 340a and the second pixel cell 340b.
[0133] In this embodiment, both the third extended segment 353 and the second main reset control line 423 are located in the first gate layer 125, and both the fourth extended segment 354 and the main light emission control line 424 are located in the first gate layer 125.
[0134] Referring to Figures 11 to 13, the two first extended segments 351 in different layers are both located in close proximity to the first pixel cell 340a, the fourth extended segment 354 is located on the side of the first extended segment 351 away from the first pixel cell 340a, the third extended segment 353 is located on the side of the fourth extended segment 354 away from the first pixel cell 340a, and the second extended segment 352 located in the third gate layer 131 is located between the first extended segment 351 and the first pixel cell 340a, which are located in two different layers, respectively.
[0135] Since multiple sub-signal lines are provided between the first pixel cell 340a and the second pixel cell 340b, when the first extended segment 351, the second extended segment 352, the third extended segment 353, and the fourth extended segment 354 are electrically connected to their corresponding sub-signal lines, a technical problem arises in which control lines transmitting different control signals are short-circuited.
[0136] Referring to Figure 12, the functional sub-section 300a further includes a first vertical segment 361 extending along the second direction Y, a second vertical segment 362, a third vertical segment 363, a fourth vertical segment 364, a fifth vertical segment 365, and a sixth vertical segment 366. The first vertical segment 361, the third vertical segment 363, the fourth vertical segment 364, the fifth vertical segment 365, and the sixth vertical segment 366 are provided between the first pixel cell 340a and the second pixel cell 340b, and the second vertical segment 362 is provided between the first pixel cell 340a and the first main section 400a.
[0137] Referring to Figure 12, the first extended segment 351 located in the second gate layer 127 is electrically connected to the sub-compensation control line 321 located in the second gate layer 127 by the first longitudinal segment 361, the second extended segment 352 located in the second gate layer 127 is electrically connected to the first sub-reset control line 322 located in the second gate layer 127 by the second longitudinal segment 362, and the third extended segment 353 is electrically connected to the second sub-reset control line 323 by the third longitudinal segment 363. The fourth extending segment 354 is electrically connected to the sub-light emission control line 324 by the fourth longitudinal segment 364, the first extending segment 351 located in the third gate layer 131 is electrically connected to the sub-compensation control line 321 located in the third gate layer 131 by the fifth longitudinal segment 365, and the second extending segment 352 located in the third gate layer 131 is electrically connected to the first sub-reset control line 322 located in the third gate layer 131 by the sixth longitudinal segment 366.
[0138] In this embodiment, the first vertical segment 361 and the sixth vertical segment 366 partially overlap. Therefore, in this application, the sixth vertical segment 366 is provided on the second source-drain layer 135, while the first vertical segment 361, the second vertical segment 362, the third vertical segment 363, the fourth vertical segment 364, and the fifth vertical segment 365 are all located on the first source-drain layer 133.
[0139] Note that Figure 12 is merely one embodiment of the present invention, and if the distance between the first pixel cell 340a and the second pixel cell 340b is insufficient to install the five vertical segments, the five vertical segments may be installed on the side of the second pixel cell 340b that is away from the first pixel cell 340a.
[0140] Referring to Figures 3 and 12, each sub-signal line group 320 of the present invention further includes a sub-switching control line 325, and each main signal line group 420 further includes a main switching control line 425. The sub-switching control lines 325 and the main switching control line 425 are used to transmit a switching control signal Pscan1, that is, the sub-switching control lines 325 and the main switching control line 425 are mainly used to turn on a switching transistor that transmits a data signal.
[0141] In this embodiment, in the functional sub-unit 300a and the first main unit 400a corresponding to the functional sub-unit 300a, a single main switching control line 425 in the first main unit 400a is electrically connected to a single sub-switching control line 325 in the functional sub-unit 300a.
[0142] For example, in the configuration shown in Figure 3, one main switching control line 425 in one first main section 400a of the present invention is electrically connected to a corresponding sub-switching control line 325. Another main switching control line 425 in the first main section 400a is installed in isolation from the sub-switching control line 325 in the corresponding functional sub-section 300a and is directly electrically connected to the main switching control line 425 in the corresponding first main section 400a on the other side of the first display area 300.
[0143] Furthermore, since the main switching control line 425 is located in the first main section 400a, this invention requires that a connection segment connecting the two main switching control lines 425 located in the same row be installed in the first display area 300.
[0144] Referring to Figure 12, the functional sub-section 300a further includes at least one electrical connection segment 371 provided around a plurality of first pixel circuits 310 in the same row. The electrical connection segment 371 is installed in isolation from the sub-switching control line 325, and one end of the electrical connection segment 371 is electrically connected to a single main switching control line 425 installed in isolation from the five sub-signal lines in the first main section 400a.
[0145] In this embodiment, the electrical connection segment 371 is provided on the outermost edge of a plurality of pixel cells 340. At the same time, since the electrical connection segment 371 needs to be connected to the main switching control line 425 in the first main section 400a located in the first gate layer 125, and the first main reset line 426 located in the first gate layer 125 needs to be electrically connected to the first sub-reset line 326 provided between the electrical connection segment 371 and the pixel cell 340, a bridge metal structure is required to electrically connect the electrical connection segment 371 and the main switching control line 425. Similarly, since the first pixel circuit 310 corresponds to the region between two rows of second pixel circuits 410, that is, in the first main section 400a, the main switching control line 425 electrically connected to the sub-switching control line 325 is not located on the same straight line, the sub-switching control line 325 and the main switching control line 425 similarly require a bridge metal structure to electrically connect the two.
[0146] Referring to Figure 12, the functional sub-section 300a includes a first bridge segment 372 and a second bridge segment 373. The first bridge segment 372 electrically connects a single main switching control line 425, which is installed insulated from the sub-switching control line 325, to an electrical connection segment 371. The second bridge segment 373 electrically connects a single main switching control line 425 to the sub-switching control line 325. The first bridge segment 372 extends along a first direction, a portion of the second bridge segment 373 extends along a second direction Y, the second bridge segment 373 is located between the second longitudinal segment 362 and the first pixel cell 340a, and both the first bridge segment 372 and the second bridge segment 373 are located in the first source-drain layer 133.

[0149] Referring to Figure 12, the plurality of signal lines further include a first sub-reset line 326, a second sub-reset line 327, and a third sub-reset line 328 located within the first display area, wherein the first sub-reset line 326 is connected to a first reset transistor T4 of a row of first pixel circuits 310 arranged along a first direction X, the second sub-reset line 327 is connected to a second reset transistor T7 of a row of first pixel circuits 310 arranged along a first direction X, and the third sub-reset line 328 is connected to a third reset transistor T8 of a row of first pixel circuits 310 arranged along a first direction X.

[0151] In this embodiment, since two main reset lines need to be electrically connected to corresponding sub-reset lines that transmit the same reset signal, the functional sub-section 300a of the present invention further includes a fifth extending segment 355, a sixth extending segment 356, and a seventh extending segment 357, wherein the fifth extending segment 355 and the seventh extending segment 357 are provided around the first pixel cell 340a, and the sixth extending segment 356 is provided between the first pixel cell 340a and the first main section 400a.
[0152] In this embodiment, one end of the fifth extending segment 355 is electrically connected to a first main reset line 426 in the first main section 400a, and the other end of the fifth extending segment 355 is electrically connected to a first sub-reset line 326 in the area where the fifth parallel connection node M5 is located.

[0153] Referring to Figure 12, the first main reset line 426 and the first sub-reset line 326 are located in the first gate layer 125, the second main reset line 427 and the second sub-reset line 327 are located in the third gate layer 131, and the third main reset line 428 and the third sub-reset line 328 are located in the second gate layer 127. On the other hand, when connecting a main reset line to a corresponding sub-reset line, a metal layer traversing the same layer is required. Therefore, the fifth extended segment 355, the sixth extended segment 356, and the seventh extended segment 357 of this application are all manufactured using the metal of the first source-drain layer 133.
[0154] In this embodiment, the fifth extending segment 355 may be installed between the first main portion 400a and the second vertical segment 362, and both the sixth extending segment 356 and the seventh extending segment 357 are provided around the first pixel cell 340a.
[0155] Since the first reset signal Vi1, the second reset signal Vi2, and the third reset signal Vi3 are all constant voltage signals, this invention forms a mesh structure by connecting reset lines that transmit the same reset signal in parallel.
[0156] Referring to Figures 14 to 16, the second display area 400 further includes a plurality of first connection segments 441, a plurality of second connection segments 442, and a plurality of third connection segments 443.

Each second connection segment 442 is electrically connected to a plurality of second main reset lines 427, and the plurality of second connection segments 442 and the plurality of second main reset lines 427 form a mesh structure. Each third connection segment 443 is electrically connected to a plurality of third main reset lines 428, and the plurality of third connection segments 443 and the plurality of third main reset lines 428 form a mesh structure.
[0158] The second main section 400b is similarly provided with multiple first main reset lines 426, multiple second main reset lines 427, and multiple third main reset lines 428. The main reset lines that transmit the same reset signal in the first main section 400a and the second main section 400b are all electrically connected to connection segments that extend in the vertical direction, forming a corresponding mesh structure. This reduces the impedance of the reset lines and improves the technical problem of the reset line voltage signal being attenuated by the effects of resistance and capacitors.
[0159] Referring to Figures 14 to 16, the multiple first connection segments 441, multiple second connection segments 442, and multiple third connection segments 443 are spaced apart along the first direction X, and the number of first connection segments 441 is less than the number of second connection segments 442, and the number of third connection segments 443 is less than the number of second connection segments 442. For example, there is a spacing of the width of eight second pixel circuits 410 between two adjacent first connection segments 441, a spacing of the width of four second pixel circuits 410 between two adjacent second connection segments 442, and a spacing of the width of eight second pixel circuits 410 between two adjacent third connection segments 443.
[0160] In this embodiment, the second reset signal Vi2 is used to reset the potential of the anode in the light-emitting element. However, if the potential of the anode in the light-emitting element is not accurate, there is a technical problem that brightness unevenness is likely to occur at low gradation levels. In this application, by installing a relatively large number of second connection segments 442, the mesh structure formed by multiple second connection segments 442 and multiple second main reset lines 427 becomes denser, further reducing the impedance of the multiple second main reset lines 427 and reducing the influence of resistors and capacitors on the voltage signal transmitted to the second main reset lines 427.
[0161] In Figures 14 to 16, each bright line in the horizontal and vertical directions represents only one wiring, and the two horizontal lines in the drawings are the boundary lines in the width direction of the corresponding wiring.

[0163] As can be seen from the table above, if the design is not based on this proposed technology, the transmittance of the first display area 300 is 17.5%.

[0167] In Comparative Example 4, when two compensation control lines transmitting the compensation control signal Nscan1, two light emission control lines transmitting the light emission control signal EM, two first reset control lines transmitting the first reset control signal Nscan2, two second reset control lines transmitting the second reset control signal Pscan2, two first reset lines transmitting the first reset signal Vi1, two second reset lines transmitting the second reset signal Vi2, and two third reset lines transmitting the third reset signal Vi3 were connected in parallel to the first display area 300, the transmittance in the first display area 300 increased from 20.5% to 24.5%.
