Description

Technical Field

[0001] This disclosure relates to a transparent display device. Background Technology

[0002] With the development of the information society, the demand for display devices for displaying images has increased in various forms. Recently, various display devices such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, organic light-emitting diode (OLED) devices, and quantum dot light-emitting diode (QLED) devices have been widely used.

[0003] Recently, research has been actively conducted on transparent display devices that allow users to view objects or images arranged on the opposite side of the display device.

[0004] A transparent display device includes a display area and a non-display area on which an image is displayed, wherein the display area may include a transmissive area and a non-transmissive area that can transmit external light. The transparent display device can have high light transmittance in the display area through the transmissive area.

[0005] When defective subpixels are present, Weighted Data for Redundancy (WDR) technology, used to restore defective subpixels to normal operation via repair lines, can be applied to transparent display devices. However, in transparent display devices using WDR technology, the size of the transmissive area may be reduced due to the repair lines, thereby potentially decreasing light transmittance. Summary of the Invention

Unless otherwise stated, singular terms may include plural forms.

[0013] When interpreting a component, although there is no explicit description, the component is interpreted as including a range of error.

[0014] When describing positional relationships, for example, when the positional relationship is described as "~above", "~above", "~below" and "adjacent to ~", one or more components may be arranged between two other components unless "exactly" or "directly" is used.

[0015] It is understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0016] In describing the elements of this disclosure, the terms “first,” “second,” etc., may be used. These terms are intended to identify the corresponding element from other elements, and the basis, order, or number of the corresponding elements is not limited by these terms. The expression that an element is “connected” or “linked” to another element should be understood to mean that the element can be directly connected or linked to the other element, but unless specifically mentioned otherwise, it can be directly connected or linked to the other element, or a third element can be inserted between the corresponding elements.

[0017] Features of the various embodiments of this disclosure may be connected or combined with each other, either partially or entirely, and may interoperate and be technically driven with each other in a variety of ways, as will be fully understood by those skilled in the art. Embodiments of this disclosure may be performed independently of each other or may be performed together in an interdependent relationship.

[0018] In the following, examples of transparent display devices according to this disclosure will be described in detail with reference to the accompanying drawings. Where possible, the same reference numerals will be used throughout the drawings to refer to the same or similar parts.

[0019] Figure 1 This is a perspective view illustrating a transparent display device according to one embodiment of the present disclosure.

[0020] In the following text, the X-axis indicates a line parallel to the scan line, the Y-axis indicates a line parallel to the data line, and the Z-axis indicates the height direction of the transparent display device 100.

[0021] Although the description has been based on the case where the transparent display device 100 according to one embodiment of the present disclosure is implemented as an organic light-emitting display device, the transparent display device 100 may be implemented as a liquid crystal display device, a plasma display panel (PDP), a quantum dot light-emitting display (QLED) or an electrophoretic display device.

[0022] Reference Figure 1 According to one embodiment of the present disclosure, a transparent display device 100 includes a transparent display panel 110, a source driver integrated circuit (IC) 210, a flexible film 220, a circuit board 230, and a timing controller 240.

[0023] The transparent display panel 110 includes a first substrate 111 and a second substrate 112 facing each other. The second substrate 112 may be an encapsulation substrate. The first substrate 111 may be a plastic film, a glass substrate, or a silicon wafer substrate formed using semiconductor processes. The second substrate 112 may be a plastic film, a glass substrate, or an encapsulation film. The first substrate 111 and the second substrate 112 may be made of transparent materials.

[0024] The scan driver can be positioned on one side of the display area of ​​the transparent display panel 110 or in the non-display areas of the two peripheral sides of the transparent display panel 110 using the in-panel gated driver (GIP) method. Alternatively, the scan driver can be fabricated in a driver chip, mounted on a flexible film, and attached to one or both peripheral sides of the display area of ​​the transparent display panel 110 using the tape auto-bonding (TAB) method.

[0025] If the source driver IC 210 is manufactured in the driver chip, the source driver IC 210 can be mounted on the flexible film 220 by the chip-on-film (COF) method or the chip-on-plastic (COP) method.

[0026] Pads such as power pads and data pads can be provided in the pad area PA of the transparent display panel 110. Lines connecting the pads to the source driver IC 210 and lines connecting the pads to the circuit board 230 can be provided in the flexible film 220. The flexible film 220 can be attached to the pads using an anisotropic conductive film, thereby allowing the pads to be connected to the lines of the flexible film 220.

[0027] Figure 2 This is a plan view illustrating a transparent display panel according to one embodiment of the present disclosure, and Figure 3 This is an example Figure 2 A magnified view of region A. Figure 4 This is an example Figure 3 A magnified view of region B. Figure 5 yes Figure 4 The cross-sectional view taken along line I-I', and Figure 6 This is a cross-sectional view illustrating the repair process of connecting defective sub-pixels with sub-pixels that are set to be adjacent to them.

[0028] Reference Figure 2 and Figure 6 The first substrate 111 may include a display area DA with pixels P for displaying images and a non-display area NDA for not displaying images.

[0029] The non-display area NDA can be configured with a pad area PA in which pads PAD are set and at least one scan driver 205.

[0030] Scan driver 205 is connected to scan line SL and provides scan signals to scan line SL. Scan driver 205 can be configured in the non-display areas NDA on one side of the display area DA of the transparent display panel 110 or on the two peripheral sides of the transparent display panel 110 using an in-panel gated driver (GIP) method. For example, as... Figure 2 As shown, the scan driver 205 can be disposed on both sides of the display area DA of the transparent display panel 110, but these scan drivers are not limited to this. The scan driver 205 can be disposed on only one side of the display area DA of the transparent display panel 110.

[0031] like Figure 3As shown, the display area DA includes a transmissive area TA and a non-transmissive area NTA. The transmissive area TA is the area through which most of the external incident light passes, and the non-transmissive area NTA is the area through which most of the external incident light cannot pass. For example, the transmissive area TA can be an area with a transmittance greater than α% (e.g., about 90%), and the non-transmissive area NTA can be an area with a transmittance less than β% (e.g., about 50%). In this case, α is greater than β. Due to the transmittance of the transmissive area TA, the user can see objects or backgrounds arranged on the rear surface of the transparent display panel 110.

[0032] The non-transmissive region NTA may include multiple pixels P, multiple first signal lines SL1, and multiple second signal lines SL2 to provide signals to each of the multiple pixels P.

[0033] Multiple first signal lines SL1 may extend from the non-transmissive region NTA in a first direction (e.g., the X-axis direction). Each of the multiple first signal lines SL1 may include multiple signal lines, and may include, for example, at least one scan line.

[0034] Multiple second signal lines SL2 may extend from the non-transmissive region NTA in a second direction (e.g., the Y-axis direction). The multiple second signal lines SL2 may intersect with multiple first signal lines SL1. Each of the multiple second signal lines SL2 may include multiple signal lines, and may include, for example, at least one of a first data line, a reference line, a pixel power line, a common power line, or a second data line. For simplification purposes, the first signal lines SL1 and the second signal lines SL2 have been shown as signal lines grouped as blocks. Figure 9 A specific illustration of multiple second signal lines SL2 is shown as an example.

[0035] The transmission region TA can be positioned between adjacent first signal lines SL1. Additionally, the transmission region TA can be positioned between adjacent second signal lines SL2. That is, the transmission region TA can be surrounded by two first signal lines SL1 and two second signal lines SL2.

[0036] Pixel P can be configured to overlap with at least one of the first signal line SL1 and the second signal line SL2, thereby emitting predetermined light to display an image. The emitting region EA can correspond to the emitting region in pixel P.

[0037] Each pixel P may include at least one of a first sub-pixel P1, a second sub-pixel P2, a third sub-pixel P3, and a fourth sub-pixel P4. The first sub-pixel P1 may include a first emitting region EA1 that emits white light. The second sub-pixel P2 may include a second emitting region EA2 that emits green light. The third sub-pixel P3 may include a third emitting region EA3 that emits blue light. The fourth sub-pixel P4 may include a fourth emitting region EA4 that emits red light. However, the emitting regions are not limited to this example. Each pixel P may also include sub-pixels that emit light of colors other than red, green, blue, and white. Furthermore, the arrangement order of sub-pixels P1, P2, P3, and P4 can be changed in various ways.

[0038] Furthermore, the light-emitting regions EA1, EA2, EA3, and EA4 respectively disposed in the multiple sub-pixels P1, P2, P3, and P4 may include light-emitting regions divided into multiple regions. Specifically, the first light-emitting region EA1 disposed in the first sub-pixel P1 may include two divided regions (i.e., a first divided light-emitting region EA11 and a second divided light-emitting region EA12). The second light-emitting region EA2 disposed in the second sub-pixel P2 may include two divided regions (i.e., a first divided light-emitting region EA21 and a second divided light-emitting region EA22). The third light-emitting region EA3 disposed in the third sub-pixel P3 may include two divided regions (i.e., a first divided light-emitting region EA31 and a second divided light-emitting region EA32). The fourth light-emitting region EA4 disposed in the fourth sub-pixel P4 may include two divided regions (i.e., a first divided light-emitting region EA41 and a second divided light-emitting region EA42). In some embodiments, the divided light-emitting regions are spaced apart from each other. For example, the first divided light-emitting region EA11 and the second divided light-emitting region EA12 of the first sub-pixel P1 are divided and spaced apart from each other.

[0039] In the following text, for ease of description, we will use the following as a model: the first sub-pixel P1 is a white sub-pixel that emits white light, the second sub-pixel P2 is a green sub-pixel that emits green light, the third sub-pixel P3 is a blue sub-pixel that emits blue light, and the fourth sub-pixel P4 is a red sub-pixel that emits red light.

[0040] The second sub-pixel P2 and the fourth sub-pixel P4 can be configured to overlap with at least a portion of the first signal line SL1, and can be configured alternately along the first signal line SL1.

[0041] The first sub-pixel P1 and the third sub-pixel P3 can be configured to overlap with at least a portion of the second signal line SL2, and can be configured alternately along the second signal line SL2.

[0042] like Figure 3As shown, the second sub-pixel P2 and the fourth sub-pixel P4 can be set in the area where the first signal line SL1 and the second signal line SL2 intersect each other, but are not limited thereto.

[0043] In another embodiment, the first sub-pixel P1 and the third sub-pixel P3 can be located in the area where the first signal line SL1 and the second signal line SL2 intersect each other. In this case, the second sub-pixel P2 and the fourth sub-pixel P4 can be spaced apart from each other, and the first sub-pixel P1 and the third sub-pixel P3 interposed therebetween are located in the area where the first signal line SL1 and the second signal line SL2 intersect each other.

[0044] Each of the first sub-pixel P1, the second sub-pixel P2, the third sub-pixel P3, and the fourth sub-pixel P4 may include circuit elements such as capacitors and thin-film transistors, as well as light-emitting elements. Thin-film transistors may include switching transistors, sensing transistors, and driving transistors TR.

[0045] The switching transistor switches on and off according to the scan signal provided to the scan line, so as to provide the data voltage from the data line to the driving transistor TR.

[0046] The sensing transistor is used to sense the threshold voltage deviation of the drive transistor TR, which can cause image quality degradation.

[0047] The driving transistor switches according to the data voltage supplied from the switching thin-film transistor to generate a data current from the power supply provided by the pixel power line, thereby providing the generated data current to the anode electrode of the sub-pixel. The driving transistor includes an active layer ACT, a gate GE, a source SE, and a drain DE.

[0048] The capacitor Cst is used to maintain the data voltage supplied to the driving transistor TR for one frame. The capacitor Cst may include two capacitor electrodes, but is not limited to this. In one embodiment, the capacitor Cst may include three capacitor electrodes.

[0049] Specifically, the active layer ACT can be disposed on the first substrate 111. The active layer ACT can be formed of a silicon-based semiconductor material or an oxide-based semiconductor material.

[0050] A light-shielding layer LS can be disposed between the active layer ACT and the first substrate 111. The light-shielding layer LS can serve as a light-shielding layer for shielding external light entering the active layer ACT. The light-shielding layer LS can be made of a conductive material. For example, the light-shielding layer LS can be formed as a single layer or multiple layers made of any one of Mo, Al, Cr, Au, Ti, Ni, Nd, and Cu or alloys thereof. In this case, a buffer film BF can be disposed between the light-shielding layer LS and the active layer ACT.

[0051] The gate insulating layer GI can be disposed on the active layer ACT. The gate insulating layer GI can be formed of an inorganic film (e.g., a silicon oxide film (SiOx), a silicon nitride film (SiNx), or a multilayer film of SiOx and SiNx).

[0052] The gate GE can be disposed on the gate insulating layer GI. The gate GE can be formed as a single layer or multiple layers made of any one of Mo, Al, Cr, Au, Ti, Ni, Nd and Cu or alloys thereof.

[0053] The interlayer dielectric layer (ILD) can be disposed on the gate electrode (GE). The interlayer dielectric layer (ILD) can be made of inorganic films (e.g., silicon oxide films (SiOx), silicon nitride films (SiNx), or multilayer films of SiOx and SiNx).

[0054] The source (SE) and drain (DE) electrodes can be disposed on the interlayer dielectric layer (ILD). The source (SE) and drain (DE) electrodes can be connected to the active layer (ACT) through contact holes passing through the gate insulating layer (GI) and the interlayer dielectric layer (ILD).

[0055] The source electrode (SE) and drain electrode (DE) can be made of any one of Mo, Al, Cr, Au, Ti, Ni, Nd and Cu or their alloys, in single or multiple layers.

[0056] A passivation layer PAS for protecting the drive transistor TR can be disposed on the source SE and drain DE. A planarization layer PLN for planarizing the step difference caused by the drive transistor TR can be disposed on the passivation layer PAS. The planarization layer PLN can be formed from an organic film such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0057] A light-emitting diode including an anode electrode 120, an organic light-emitting layer 130 and a cathode electrode 140, and a dam 125 are disposed on a planarization layer PLN.

[0058] The anode electrode 120 can be disposed on the planarization layer PLN and connected to the driving transistor TR. The anode electrode 120 can be disposed for each of the sub-pixels P1, P2, P3, and P4. One anode electrode 120 can be disposed in the first sub-pixel P1, another anode electrode 120 can be disposed in the second sub-pixel P2, yet another anode electrode 120 can be disposed in the third sub-pixel P3, and yet another anode electrode 120 can be disposed in the fourth sub-pixel P4. The anode electrode 120 is not disposed in the transmission region TA.

[0059] The anode electrode 120 can be formed of a highly reflective metallic material such as an aluminum and titanium deposition structure (Ti / Al / Ti), an aluminum and ITO deposition structure (ITO / Al / ITO), an Ag alloy with an Ag alloy and ITO deposition structure (ITO / Ag alloy / ITO), or a MoTi alloy with a MoTi alloy and ITO deposition structure (ITO / MoTi alloy / ITO). The Ag alloy can be an alloy of silver (Ag), palladium (Pb), and copper (Cu). The MoTi alloy can be an alloy of molybdenum (Mo) and titanium (Ti).

[0060] The anode electrode 120 included in each of the plurality of sub-pixels P1, P2, P3 and P4 may include a plurality of anode electrodes. For example, the anode electrode 120 included in each of the plurality of sub-pixels P1, P2, P3 and P4 may include a first anode electrode 121 and a second anode electrode 122.

[0061] The first anode electrode 121 can be disposed in the first divided light-emitting regions EA11, EA21, EA31 and EA41, and the second anode electrode 122 can be disposed in the second divided light-emitting regions EA12, EA22, EA32 and EA42. The first anode electrode 121 and the second anode electrode 122 can be disposed on the same layer and spaced apart from each other.

[0062] According to one embodiment of this disclosure, the transparent display panel 110 may further include an anode connection electrode ACE for connecting the first anode electrode 121 and the second anode electrode 122. For example... Figure 4 As shown, the anode connection electrode ACE may include a first anode connection portion ACE1, a second anode connection portion ACE2, a third anode connection portion ACE3, and a fourth anode connection portion ACE4. In some embodiments, the first anode connection portion ACE1, the second anode connection portion ACE2, the third anode connection portion ACE3, and the fourth anode connection portion ACE4 at least partially overlap with the transmission region TA (e.g., with...). Figure 4 The first transmission region TA1 overlaps in the middle.

[0063] The first anode connection portion ACE1 can extend from the first anode electrode 121 toward the transmission region TA by a predetermined length. The second anode connection portion ACE2 can extend from the second anode electrode 122 toward the transmission region TA by a predetermined length.

[0064] The third anode connection portion ACE3 can connect one end of the first anode connection portion ACE1 to one end of the second anode connection portion ACE2. Therefore, the first anode electrode 121 can be electrically connected to the second anode electrode 122 through the anode connection electrode ACE.

[0065] The fourth anode connection portion ACE4 may extend from the third anode connection portion ACE3 and be configured to overlap at least a portion of the repair wire RL. The fourth anode connection portion ACE4 may be connected to the repair wire RL, or may be electrically disconnected from the repair wire RL by means of at least one insulating layer inserted therebetween.

[0066] Specifically, the fourth anode connection portions ACE4 of some sub-pixels P1, P2, P3, and P4 can be connected to the repair line RL via the first repair contact portion RCNT1. The fourth anode connection portions ACE4 of other sub-pixels P1, P2, P3, and P4 can be electrically disconnected from the repair line RL using at least one insulating layer (e.g., a planarization layer PLN and a passivation layer PAS) inserted therebetween. When a defective sub-pixel occurs, the electrically disconnected fourth anode connection portions ACE4 and the repair line RL can be electrically connected to each other through a repair process. The repair line RL and the repair process will be described later.

[0067] The first anode connection portion ACE1, the second anode connection portion ACE2, the third anode connection portion ACE3, and the fourth anode connection portion ACE4 can be integrally formed on the same layer as the first anode electrode 121 and the second anode electrode 122. The regions forming the first anode connection portion ACE1, the second anode connection portion ACE2, the third anode connection portion ACE3, and the fourth anode connection portion ACE4 can be non-transmissive regions (NTA), but are not limited thereto. In another embodiment, the first anode connection portion ACE1, the second anode connection portion ACE2, the third anode connection portion ACE3, and the fourth anode connection portion ACE4 can be made of a transparent conductive material. In this case, the regions forming the first anode connection portion ACE1, the second anode connection portion ACE2, the third anode connection portion ACE3, and the fourth anode connection portion ACE4 can be transmissive regions (TA).

[0068] The anode electrode 120 can be electrically connected to the drive transistor TR through the anode connection electrode ACE and the transistor connection electrode TCE.

[0069] The transistor connection electrode TCE can be disposed between the first anode connection portion ACE1 and the second anode connection portion ACE2. The transistor connection electrode TCE can extend a predetermined length from the source SE or drain DE of the driving transistor TR toward the transmission region TA. At least a portion of the transistor connection electrode TCE can overlap with the third anode connection portion ACE3 and can be electrically connected to the third anode connection portion ACE3 through a first contact hole CH1 in the region overlapping with the third anode connection portion ACE3.

[0070] The region forming the transistor connection electrode TCE can be a non-transmissive region NTA, but is not limited thereto. A transmissive region TA can be disposed between the transistor connection electrode TCE and the first anode connection portion ACE1, and between the transistor connection electrode TCE and the second anode connection portion ACE2. In another embodiment, the transistor connection electrode TCE can be made of a transparent conductive material. In this case, the region forming the transistor connection electrode TCE can be the transmissive region TA. In a transparent display panel 110 according to one embodiment of the present disclosure, particles may enter either the first anode electrode 121 or the second anode electrode 122 during any process including the manufacturing process, potentially resulting in black spots. In this case, the transparent display panel 110 according to one embodiment of the present disclosure can be repaired by cutting at least one of the first anode connection portion ACE1 or the second anode connection portion ACE2 of the anode connection electrode ACE.

[0071] For example, in a transparent display panel 110 according to one embodiment of the present disclosure, when a short circuit occurs between the first anode electrode 121 and the cathode electrode 140 due to particles in the region where the first anode electrode 121 is disposed, the first anode connection portion ACE1 can be repaired by cutting along the first cutting line C1.

[0072] For example, in a transparent display panel 110 according to one embodiment of the present disclosure, when a short circuit occurs between the second anode electrode 122 and the cathode electrode 140 due to particles in the region where the second anode electrode 122 is disposed, the second anode connection portion ACE2 can be repaired by cutting along the third cutting line C3.

[0073] In a transparent display panel 110 according to one embodiment of the present disclosure, even if black spots appear in the display panel due to foreign matter or external particles, one of the anode electrodes of the plurality of anode electrodes 121 and 122 can be opened by cutting (e.g., laser cutting or any suitable cutting method). That is, by short-circuiting any one of the anode electrodes 121 and 122 associated with the black spot problem, the occurrence of black spots can be reduced, and the light loss rate caused by dark spots can be reduced.

[0074] Furthermore, in the transparent display panel 110 according to one embodiment of the present disclosure, a defect may occur in the driving transistor TR. When the transparent display panel 110 according to one embodiment of the present disclosure malfunctions due to the driving transistor TR, the transistor connection electrode TCE can be cut along the second cutting line C2 to electrically disconnect the driving transistor TR of the corresponding sub-pixel from the anode electrode 120. Therefore, the signal applied from the driving transistor TR is prevented from being applied to the sub-pixel with the defect in the driving transistor TR, thereby preventing the sub-pixel from emitting light.

[0075] According to one embodiment of the present disclosure, a transparent display panel 110 can apply the signal of another adjacent sub-pixel to the defective sub-pixel via a repair line RL.

[0076] Specifically, a transparent display panel 110 according to one embodiment of the present disclosure may include a repair line RL on at least one side of the transmissive region TA. The repair line RL may include at least two of the following: a first repair line RL1 disposed between two adjacent first sub-pixels P1, a second repair line RL2 disposed between two adjacent second sub-pixels P2, a third repair line RL3 disposed between two adjacent third sub-pixels P3, and a fourth repair line RL4 disposed between two adjacent fourth sub-pixels P4.

[0077] The transmission region TA can be divided into a first transmission region TA1 and a second transmission region TA2 based on the location where the repair line RL is set. In the first transmission region TA1, the repair line RL can be set on one side parallel to the first direction and can extend in the first direction.

[0078] For example, such as Figure 3 As shown, a first repair line RL1 can be provided at a first side S1 parallel to the first direction in the first transmission region TA1. The first repair line RL1 can extend along the first side S1 of the first transmission region TA1 in the first direction. At this time, the first repair line RL1 can be provided between two first sub-pixels P1 that are adjacent to each other along the first direction.

[0079] Additionally, the first transmission region TA1 may include, but is not limited to, a first repair line RL1. The first transmission region TA1 may also include a third repair line RL3 facing the first repair line RL1.

[0080] For example, such as Figure 3As shown, a third repair line RL3 can be provided on the third side S3 of the first transmission region TA1, which is parallel to the first direction and faces the first side S1. The third repair line RL3 can extend along the third side S3 of the first transmission region TA1 in the first direction. At this time, the third repair line RL3 can face the first repair line RL1 and can be provided between two third sub-pixels P3 that are adjacent to each other along the first direction.

[0081] The second transmission region TA2 can be located on the opposite side of the first transmission region TA1, with the non-transmission region NTA interposed therebetween. Unlike the first transmission region TA1, in the second transmission region TA2, the repair line RL can be set to be parallel to the second direction and can extend in the second direction.

[0082] For example, such as Figure 3 As shown, a second repair line RL2 can be provided at a second side S2 parallel to the second direction in the second transmission region TA2. The second repair line RL2 can extend along the second side S2 of the second transmission region TA2 in the second direction. In this case, the second repair line RL2 can be provided between two second sub-pixels P2 that are adjacent to each other along the second direction.

[0083] The second transmission region TA2 may include, but is not limited to, a second repair line RL2. The second transmission region TA2 may also include a fourth repair line RL4 facing the second repair line RL2.

[0084] For example, such as Figure 3 As shown, a fourth repair line RL4 can be provided on the fourth side S4 facing the second side S2, parallel to the second direction, in the second transmission region TA2. The fourth repair line RL4 can extend along the fourth side S4 of the second transmission region TA2 in the second direction. At this time, the fourth repair line RL4 faces the second repair line RL2 and can be positioned between two fourth sub-pixels P4 that are adjacent to each other along the second direction.

[0085] Each of the first repair line RL1, second repair line RL2, third repair line RL3, and fourth repair line RL4, as described above, can be electrically connected at one end to an anode connection electrode ACE of two adjacent sub-pixels via the first repair contact portion RCNT1. Each of the first repair line RL1, second repair line RL2, third repair line RL3, and fourth repair line RL4 can be electrically disconnected at the other end from another anode connection electrode ACE of the two adjacent sub-pixels using at least one insulating layer (e.g., planarization layer PLN and passivation layer PAS) interposed therebetween.

[0086] Specifically, first sub-pixels P1 can be arranged to be adjacent to each other in a first direction, with a first transmissive region TA1 interposed therebetween. An anode connecting electrode ACE extending from the anode electrode 120 of the first sub-pixel P1 can be disposed at a second side S2 or a fourth side S4 located between the first side S1 and the third side S3 of the first transmissive region TA1. An anode connecting electrode ACE extending from the anode electrode 120 of one first sub-pixel P1 can be disposed at the second side S2 of the first transmissive region TA1, and an anode connecting electrode ACE extending from the anode electrode 120 of another first sub-pixel P1 can be disposed at the fourth side S4 of the first transmissive region TA1. As a result, the anode connecting electrode ACE of one first sub-pixel P1 and the anode connecting electrode ACE of another first sub-pixel P1 adjacent to one sub-pixel P1 can be arranged to face each other, with the first transmissive region TA1 interposed therebetween.

[0087] The first repair line RL1 can be electrically connected to the fourth anode connection portion ACE4 of the anode connection electrode ACE of a first sub-pixel Pl through the first repair contact portion RCNT1, which passes through the planarization layer PLN and the passivation layer PAS at one end.

[0088] At least a portion of the first repair line RL1 can overlap at its other end with the fourth anode connection portion ACE4 of the anode connection electrode ACE of another first sub-pixel P1 to form a solder joint WP. In this case, the first repair line RL1 can be electrically disconnected from the fourth anode connection portion ACE4, and the planarization layer PLN and the passivation layer PAS can be interposed therebetween. The fourth anode connection portion ACE4 can be formed planarly on the planarization layer PLN, but as... Figure 5 As shown, a step difference can be formed at the weld point WP along the hole provided in the planarization layer PLN. Specifically, since the planarization layer PLN is relatively thick, the planarization layer PLN can be partially removed from the position corresponding to the weld point WP to form the hole. Therefore, the fourth anode connection portion ACE4 can be spaced apart from the first repair line RL1 in the weld point WP, and only the passivation layer PAS is inserted therebetween.

[0089] Therefore, before performing the repair process, a signal applied to a first sub-pixel P1 cannot be applied to another first sub-pixel P1 that is adjacent to a first sub-pixel P1.

[0090] However, when a defect occurs in the driving transistor TR of either one of the first sub-pixels P1 and the other first sub-pixels P1, a repair process can be performed to connect the defective first sub-pixel P1 with the normal first sub-pixel P1.

[0091] The repair process may include a testing process, a cutting process, and a welding process. The testing process can detect defects in multiple sub-pixels P1, P2, P3, and P4. The cutting process can cut the transistor connection electrode TCE to prevent signals applied from the driving transistor TR from being applied to the first sub-pixel P1 determined to be defective. That is, the cutting process included in the repair process involves electrically disconnecting one component from another. On the other hand, the welding process included in the repair process involves electrically connecting one component to another. Details of the welding process will be described in detail below with reference to the accompanying drawings.

[0092] The welding process can electrically connect the normal first sub-pixel P1 to the defective first sub-pixel P1 to apply the signal of the normal first sub-pixel P1 adjacent to the defective first sub-pixel P1 to the defective first sub-pixel P1. Specifically, as... Figure 6 As shown, the welding process can electrically connect the other end of the first repair line RL1 and the fourth anode connection portion ACE4 of the anode connection electrode ACE by irradiating the welding point WP where the first repair line RL1 and the fourth anode connection portion ACE4 of the anode connection electrode ACE overlap. In this case, the welding process can irradiate the lower portion of the first repair line RL1 or the upper portion of the fourth anode connection portion ACE4. The welding process can be performed before depositing the light-emitting layer 130 or the cathode electrode 140, and in this case, the other end of the first repair line RL1 and the fourth anode connection portion ACE4 of the anode connection electrode ACE can be electrically connected by irradiating the upper portion of the fourth anode connection portion ACE4. Alternatively, the welding process can be performed after depositing the light-emitting layer 130 or the cathode electrode 140, and in this case, the other end of the first repair line RL1 and the fourth anode connection portion ACE4 of the anode connection electrode ACE can be electrically connected by irradiating the lower portion of the first repair line RL1.

[0093] In a transparent display panel 110 according to one embodiment of the present disclosure, the other end of the first repair line RL1 and the fourth anode connection portion ACE4 of the anode connection electrode ACE can be connected to each other through a repair process, thereby applying the signal of the first sub-pixel P1 in a normal state to the first sub-pixel P1 with defects.

[0094] Furthermore, the second sub-pixels P2 can be positioned adjacent to each other in the second direction, with the second transmission region TA2 interposed therebetween. An anode connecting electrode ACE extending from the anode electrode 120 of the second sub-pixel P2 can be positioned at a first side S1 or a third side S3 located between the second side S2 and the fourth side S4 of the second transmission region TA2. An anode connecting electrode ACE extending from the anode electrode 120 of one second sub-pixel P2 can be positioned at the first side S1 of the second transmission region TA2, and an anode connecting electrode ACE extending from the anode electrode 120 of another second sub-pixel P2 adjacent to one second sub-pixel P2 can be positioned at the third side S3 of the second transmission region TA2. As a result, the anode connecting electrode ACE of one second sub-pixel P2 and the anode connecting electrode ACE of another second sub-pixel P2 adjacent to one second sub-pixel P2 can be positioned facing each other, with the second transmission region TA2 interposed therebetween.

[0095] The second repair line RL2 can be electrically connected to the fourth anode connection portion ACE4 of the anode connection electrode ACE of a second sub-pixel P2 through the first repair contact portion RCNT1, which passes through the planarization layer PLN and the passivation layer PAS at one end.

[0096] At least a portion of the second repair line RL2 can overlap at its other end with the fourth anode connection portion ACE4 of the anode connection electrode ACE of another second sub-pixel P2 to form a solder joint WP. At this time, the second repair line RL2 can be electrically disconnected from the fourth anode connection portion ACE4 at the solder joint WP, and the planarization layer PLN and the passivation layer PAS can be inserted therebetween.

[0097] Therefore, a signal applied to one second sub-pixel P2 cannot be applied to another second sub-pixel P2 adjacent to one second sub-pixel P2 until the repair process is performed.

[0098] However, when a defect occurs in the driving transistor TR of either one of the second sub-pixels P2 or the other second sub-pixel P2, a repair process can be performed that connects the defective second sub-pixel P2 to the normal second sub-pixel P2.

[0099] The repair process can be achieved by cutting the transistor connection electrode TCE to prevent the signal applied from the driving transistor TR from being applied to the second sub-pixel P2, which is determined to be defective.

[0100] The repair process can electrically connect the normal second sub-pixel P2 with the defective second sub-pixel P2 to apply the signal of the normal second sub-pixel P2 to the defective second sub-pixel P2. Specifically, the welding process can electrically connect the other end of the electrically disconnected second repair line RL2 and the fourth anode connection portion ACE4 of the anode connection electrode ACE to each other by irradiating the welding point WP where the second repair line RL2 and the fourth anode connection portion ACE4 of the anode connection electrode ACE overlap with each other using a laser.

[0101] In a transparent display panel 110 according to one embodiment of the present disclosure, the other end of the second repair line RL2 and the fourth anode connection portion ACE4 of the anode connection electrode ACE of the second sub-pixel P2 can be connected to each other through the repair process, so that the signal of the normal state of the second sub-pixel P2 can be applied to the defective second sub-pixel P2.

[0102] Furthermore, since the third repair line RL3 is arranged parallel to the first repair line RL1, and the first transmission region TA1 is interposed between them, the sub-pixels connected to the third repair line RL3 are different from those connected to the first repair line RL1, but the essentially the same connection structure or repair process is applied to these repair lines. Therefore, a detailed description of the connection structure and repair process of the third repair line RL3 will be omitted.

[0103] Furthermore, since the fourth repair line RL4 is arranged parallel to the second repair line RL2, and the second transmission region TA2 is interposed between them, the sub-pixels connected to the fourth repair line RL4 are different from those connected to the second repair line RL2, but the essentially the same connection structure or repair process is applied to these repair lines. Therefore, a detailed description of the connection structure and repair process of the fourth repair line RL4 will be omitted.

[0104] Repair lines RL1, RL2, RL3, and RL4 can be disposed on one of the layers other than the layer on which the anode electrode 120 is disposed. Repair lines RL1, RL2, RL3, and RL4 can be disposed on the same layer as any one of the light-shielding layer LS, the active layer ACT, the gate GE, the source SE, and the drain DE.

[0105] For example, when the light-shielding layer LS is formed of a conductive material, the repair lines RL1, RL2, RL3 and RL4 can be formed on the same layer as the light-shielding layer LS.

[0106] For another example, repair lines RL1, RL2, RL3, and RL4 can be disposed on the same layer as the source SE or drain DE. When repair lines RL1, RL2, RL3, and RL4 are disposed on the same layer as the source SE or drain DE, the number of contact portions can be reduced and the size of the contact portions can be reduced compared to the case where repair lines RL1, RL2, RL3, and RL4 are disposed on the same layer as the light-shielding layer LS.

[0107] When the repair lines RL1, RL2, RL3, and RL4 are disposed on the same layer as the light-shielding layer LS, the second repair contact portion RCNT2, passing through the buffer layer BF, gate insulating layer GI, interlayer dielectric layer ILD, passivation layer PAS, and planarization layer PLN, may advantageously connect to the fourth anode connection portion ACE4 of the anode connection electrode ACE. In this case, the second repair contact portion RCNT2 may not be easily formed in a single pass through the buffer layer BF, gate insulating layer GI, interlayer dielectric layer ILD, passivation layer PAS, and planarization layer PLN, and may be formed multiple times. For example, the second repair contact portion RCNT2 may include a first contact portion passing through the buffer layer BF, gate insulating layer GI, and interlayer dielectric layer ILD, and a second contact portion passing through the passivation layer PAS and planarization layer PLN.

[0108] Thus, when the repair lines RL1, RL2, RL3 and RL4 are placed on the same layer as the light-shielding layer LS, the size of the contact portions needs to be increased to form overlapping contact portions since multiple contact portions need to be formed.

[0109] On the other hand, when the repair lines RL1, RL2, RL3, and RL4 are disposed on the same layer as the source SE or drain DE, the second repair contact portion RCNT2 passing through the passivation layer PAS and the planarization layer PLN may be advantageous. In this case, since the second repair contact portion RCNT2 only needs to pass through the passivation layer PAS and the planarization layer PLN, only one contact portion is formed. Therefore, when the repair lines RL1, RL2, RL3, and RL4 are disposed on the same layer as the source SE or drain DE, the size of the contact portion disposed in the transmission region TA can be reduced or minimized, and the light loss rate caused by the application of the repair structure can be reduced or minimized.

[0110] A dam 125 can be disposed on the planarization layer PLN. Additionally, the dam 125 can be disposed between the anode electrodes 120. The dam 125 can be formed to cover or at least partially cover the edge of each anode electrode 120 and expose a portion of each anode electrode 120. Therefore, the dam 125 can prevent the luminous efficiency from deteriorating due to current concentrated at each end of the anode electrode 120.

[0111] The dam 125 can define the light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41, and EA42 for each of the sub-pixels P1, P2, P3, and P4. The light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41, and EA42 for each of the sub-pixels P1, P2, P3, and P4 refer to the regions where the anode electrode 120, the organic light-emitting layer 130, and the cathode electrode 140 are sequentially deposited such that holes from the anode electrode 120 and electrons from the cathode electrode 140 combine with each other in the organic light-emitting layer 130 to emit light. In this case, since the region forming the dam 125 does not emit light, this region can be a non-light-emitting region, and the regions where the dam 125 is not formed and the anode electrode 120 is exposed can be the light-emitting regions EA11, EA12, EA21, EA22, EA31, EA32, EA41, and EA42.

[0112] Alternatively, the embankment 125 may be provided on the repair lines RL1, RL2, RL3 and RL4 formed on at least one side of the transmission region TA, and the anode connecting electrode ACE is formed to protrude from the light-emitting region to the transmission region TA.

[0113] The embankment 125 may be formed of an organic layer (e.g., acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, etc.).

[0114] An organic light-emitting layer 130 may be disposed on the anode electrode 120. The organic light-emitting layer 130 may include a hole transport layer, a light-emitting layer, and an electron transport layer. In this case, if a voltage is applied to the first anode electrode 120 and the cathode electrode 140, holes and electrons move to the light-emitting layer through the hole transport layer and the electron transport layer, respectively, and combine with each other in the light-emitting layer to emit light.

[0115] In one embodiment, the organic light-emitting layer 130 may be a common layer shared by sub-pixels P1, P2, P3, and P4. For example, the organic light-emitting layer 130 may be a white light-emitting layer that emits white light.

[0116] In another embodiment, the organic light-emitting layer 130 may include light-emitting layers disposed in sub-pixels P1, P2, P3, and P4. For example, a white light-emitting layer emitting white light may be disposed in the first sub-pixel P1, a green light-emitting layer emitting green light may be disposed in the second sub-pixel P2, a blue light-emitting layer emitting blue light may be disposed in the third sub-pixel P3, and a red light-emitting layer emitting red light may be disposed in the fourth sub-pixel P4. In this case, the light-emitting layers of the organic light-emitting layer 130 are not disposed in the transmissive region TA.

[0117] The cathode electrode 140 can be disposed on the organic light-emitting layer 130 and the embankment 125. The cathode electrode 140 can be disposed in the transmissive region TA and the non-transmissive region NTA including the light-emitting region EA, but is not limited thereto. The cathode electrode 140 can be disposed only in the non-transmissive region NTA including the light-emitting region EA, but can be disposed outside the transmissive region TA to improve transmittance.

[0118] The cathode electrode 140 may be a common layer disposed in sub-pixels P1, P2, P3, and P4 to apply the same voltage. The cathode electrode 140 may be formed of a light-transmitting conductive material. For example, the cathode electrode 140 may be formed of a low-resistance metallic material (e.g., Ag or an alloy of Mg and Ag).

[0119] An encapsulation layer 150 can be disposed on the light-emitting diode. The encapsulation layer 150 can be disposed on the cathode electrode 140 to cover the cathode electrode 140. The encapsulation layer 150 is used to prevent oxygen or water from penetrating into the organic light-emitting layer 130 and the cathode electrode 140. For this purpose, the encapsulation layer 150 may include at least one inorganic layer and at least one organic layer.

[0120] Furthermore, despite Figure 5 and Figure 6 It is not shown in the figure, but an outer coating layer may be provided between the cathode electrode 140 and the encapsulation layer 150.

[0121] A color filter CF can be disposed on the encapsulation layer 150. The color filter CF can also be disposed on a surface of the second substrate 112 facing the first substrate 111. In this case, the first substrate 111 with the encapsulation layer 150 and the second substrate 112 with the color filter CF can be bonded to each other via an adhesive layer 160. Here, the adhesive layer 160 can be an optically clear resin (OCR) layer or an optically clear adhesive (OCA) film.

[0122] The color filter CF can be patterned for each of the sub-pixels P1, P2, P3, and P4. Specifically, the color filter CF can include a first color filter CF1, a second color filter CF2, and a third color filter CF3. A transparent color filter made of transparent organic material can be provided in the first sub-pixel P1, or no separate color filter may be provided. The first color filter CF1 can be set to correspond to the light-emitting area EA2 of the second sub-pixel P2, and can be a green color filter that transmits green light. The second color filter CF2 can be set to correspond to the light-emitting area EA3 of the third sub-pixel P3, and can be a blue color filter that transmits blue light. The third color filter CF3 can be set to correspond to the light-emitting area EA4 of the fourth sub-pixel P4, and can be a red color filter that transmits red light.

[0123] In a transparent display panel 110 according to one embodiment of the present disclosure, no polarizer is used, and a color filter CF is formed in a second substrate 112. When a polarizer is attached to the transparent display panel 110, the polarizer reduces the transmittance of the transparent display panel 110. When the polarizer is not attached to the transparent display panel 110, there is a problem of external incident light being reflected in the electrodes.

[0124] A transparent display panel 110 according to one embodiment of the present disclosure can prevent a reduction in transmittance because a polarizer is not attached thereto. Furthermore, in the transparent display panel 110 according to one embodiment of the present disclosure, a color filter CF can be formed in the second substrate 112 to partially absorb external incident light, thereby preventing the incident light from being reflected in the electrodes. In other words, the transparent display panel 110 according to one embodiment of the present disclosure can reduce external light reflectivity without reducing transmittance.

[0125] Furthermore, a black matrix BM can be placed between color filters CF and between color filters CF and the transmission region TA. The black matrix BM can be placed between sub-pixels P1, P2, and P3 to prevent color mixing between adjacent sub-pixels P1, P2, and P3. The black matrix BM can be placed between sub-pixels P1, P2, P3, and P4 and the transmission region TA so that light emitted from sub-pixels P1, P2, P3, and P4 does not shift to one side (e.g., the transmission region TA).

[0126] Black matrix (BM) can include light-absorbing materials, such as black dyes that completely absorb the wavelength range of visible light.

[0127] A transparent display panel 110 according to one embodiment of the present disclosure is characterized in that the position and extension direction of the repair line RL are different between the first transmission region TA1 and the second transmission region TA2.

[0128] Specifically, in a transparent display panel 110 according to one embodiment of the present disclosure, the repair line RL can extend from the first transmissive region TA1 along a first side S1 or a third side S3 of the first transmissive region TA1 in a first direction. Additionally, in a transparent display panel 110 according to one embodiment of the present disclosure, the repair line RL can extend from the second transmissive region TA2 along a second side S2 or a fourth side S4 of the second transmissive region TA2 in a second direction.

[0129] In a transparent display panel 110 according to one embodiment of the present disclosure, the repair lines RL can be spaced apart from each other without overlapping. In this case, the spacing between the repair lines RL can be greater than the width of the non-transmissive region NTA.

[0130] When a repair line RL is positioned to partially overlap or adjoin another repair line RL, its length increases because the repair line RL extends by bypassing the repair contact portion of the other repair line RL. In the transparent display panel 110, the repair line RL can be located within the transmissive region TA. In this case, as the area of ​​the repair line RL increases, the size of the transmissive region TA decreases, potentially leading to a deterioration in light transmittance.

[0131] On the other hand, in the transparent display panel 110 according to one embodiment of the present disclosure, since each of the repair lines RL is not configured to overlap or be adjacent to another repair line RL, the repair lines do not need to bypass the repair contact portion. In the transparent display panel 110 according to one embodiment of the present disclosure, since the repair lines RL can be formed as straight lines, their length can be reduced. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can prevent the size of the transmissive region TA from decreasing due to the repair lines RL. That is, in the transparent display panel 110 according to one embodiment of the present disclosure, the degradation of light transmittance caused by the repair lines RL can be reduced.

[0132] Furthermore, in a transparent display panel 110 according to one embodiment of the present disclosure, based on the above-described features, the repair line RL may not overlap with the first signal line SL1 and the second signal line SL2.

[0133] When subpixels of different colors are positioned between subpixels of the same color, the repair line RL can partially overlap with either the first signal line SL1 or the second signal line SL2 to connect the subpixels of the same color to each other. In this case, the parasitic capacitance between the repair line RL and multiple signal lines may increase.

[0134] In a transparent display panel 110 according to one embodiment of the present disclosure, since the repair lines RL face each other and the sub-pixels of the same color interposed between the first transmissive region TA1 or the second transmissive region TA2 are connected to each other, the repair lines RL can be spaced sufficiently from the first signal line SL1 or the second signal line SL2 without overlapping with them. Therefore, the transparent display panel 110 according to one embodiment of the present disclosure can reduce or minimize the parasitic capacitance between the repair lines RL and the multiple signal lines.

[0135] although Figures 3 to 6 The repair line RL is shown to be set in the transmission region TA, but the repair line RL is not limited to this.

[0136] In another embodiment, the repair line RL can be disposed in the non-transmissive region NTA. Referring below... Figures 7 to 10A detailed description of an implementation method in which the repair line RL is set in the non-transmissive region NTA.

[0137] Figure 7 This is an example Figure 3 A magnified view of the modified example in region B. Figure 8 It is along Figure 7 A cross-sectional view taken from line II-II'. Figure 9 yes Figure 3 An enlarged view of the modified example in region C, and Figure 10 It is along Figure 9 The cross-sectional view taken from line III-III'.

[0138] Figures 7 to 9 The transparent display panel 110 shown is Figures 3 to 6 The difference in the transparent display panel 110 shown is that the repair line RL is set in the non-transmissive area NTA. Repeated descriptions will be omitted below, and the following description will be based on… Figures 3 to 6 The differences.

[0139] Reference Figure 7 and Figure 8 First sub-pixels P1 can be arranged to be adjacent to each other in a first direction, with a first transmissive region TA1 interposed therebetween. An anode connecting electrode ACE extending from the anode electrode 120 of one first sub-pixel P1 can be disposed at the second side S2 of the first transmissive region TA1, and an anode connecting electrode ACE extending from the anode electrode 120 of another first sub-pixel P1 can be disposed at the fourth side S4 of the first transmissive region TA1. As a result, the anode connecting electrode ACE of one first sub-pixel P1 and the anode connecting electrode ACE of another first sub-pixel P1 adjacent to one first sub-pixel P1 can be arranged to face each other, with the first transmissive region TA1 interposed therebetween.

[0140] The first repair line RL1 can be disposed between two first sub-pixels P1 that are adjacent to each other in the first direction, and can extend along the first side S1 of the first transmissive region TA1 in the first direction. At this time, the first repair line RL1 is not disposed in the first transmissive region TA1, and at least a portion of the first repair line RL1 can overlap with the non-transmissive region NTA.

[0141] Specifically, the non-transmissive region NTA may include an external emitting region EA in which light emitted from each of the sub-pixels P1, P2, P3, and P4 is emitted to the outside. A black matrix BM may be disposed between the first transmissive region TA1 and the emitting region EA to prevent light emitted from each of the plurality of sub-pixels P1, P2, P3, and P4 from moving to the first transmissive region TA1.

[0142] like Figure 7 and Figure 8 As shown, at least a portion of the first repair line RL1 may overlap with the black matrix BM. In one embodiment, the boundary between the first repair line RL1 and the first transmission region TA1 may be aligned with or matched with the boundary line BML between the black matrix BM and the first transmission region TA1.

[0143] However, one end of the first repair line RL1 may protrude toward the first transmission region TA1 to reach the first repair contact portion RCNT1, so as to be electrically connected to the fourth anode connection portion ACE4 of the anode connection electrode ACE of a first sub-pixel P1.

[0144] In addition, the other end of the first repair line RL1 can protrude toward the first transmission area TA1 to reach the welding point WP, so as to overlap with the fourth anode connection portion ACE4 of the anode connection electrode ACE of another first sub-pixel P1.

[0145] In a transparent display panel 110 according to another embodiment of the present disclosure, even if the first repair contact portion RCNT1 and the solder point WP are formed in the first transmissive region TA1, a large portion of the first repair line RL1 can be disposed in the non-transmissive region NTA. Therefore, in the transparent display panel 110 according to another embodiment of the present disclosure, the reduction in the size of the first transmissive region TA caused by the first repair line RL1 can be reduced or minimized. That is, in the transparent display panel 110 according to one embodiment of the present disclosure, the degradation of light transmittance caused by the first repair line RL1 can be reduced or minimized.

[0146] The third repair line RL3 was not in Figure 7 and Figure 8 The details are shown below. However, the third repair line RL3 is arranged parallel to the first repair line RL1, with the first transmission region TA1 interposed therebetween. The sub-pixels connected to the third repair line RL3 are different from those connected to the first repair line RL1, but essentially the same connection structure or repair process is applied to these repair lines. Therefore, a detailed description of the arrangement of the third repair line RL3 will be omitted.

[0147] Reference Figure 9 and Figure 10The second sub-pixels P2 can be arranged to be adjacent to each other in the second direction, with the second transmission region TA2 interposed therebetween. An anode connecting electrode ACE extending from the anode electrode 120 of one second sub-pixel P2 can be disposed at the first side S1 of the second transmission region TA2, and an anode connecting electrode ACE extending from the anode electrode 120 of another second sub-pixel P2 can be disposed at the third side S3 of the second transmission region TA2. As a result, the anode connecting electrode ACE of one second sub-pixel P2 and the anode connecting electrode ACE of another second sub-pixel P2 adjacent to one second sub-pixel P2 can be arranged to face each other, with the second transmission region TA2 interposed therebetween.

[0148] The second repair line RL2 can be set between two second sub-pixels P2 that are adjacent to each other in the second direction, and can extend along the second side S2 of the second transmission region TA2 in the second direction. At this time, as... Figure 9 and Figure 10 As shown, the second repair line RL2 can be set parallel to the second signal line SL2.

[0149] The second signal line SL2 may include a pixel power line VDDL, a first data line DL1, a reference line REFL, a second data line DL2, and a common power line VSSL.

[0150] The reference line REFL can be set in the non-transmissive region NTA and extend in a second direction (e.g., the Y-axis direction). The reference line REFL can provide a reference voltage (or initialization voltage or sensing voltage) to the driving transistor TR of each of the sub-pixels P1, P2, P3 and P4.

[0151] A first data line DL1 can be disposed in the non-transmissive region NTA, located on the first side of the reference line REFL, and extending in a second direction (e.g., the Y-axis direction). The first data line DL1 can provide data voltage to at least a portion of sub-pixels P1, P2, P3, and P4. A second data line DL2 can be disposed in the non-transmissive region NTA, located on the second side of the reference line REFL, and extending in a second direction (e.g., the Y-axis direction). In this case, the second side of the reference line REFL can be the side facing the first side. The second data line DL2 can provide data voltage to the sub-pixels of P1, P2, P3, and P4 other than those connected to the first data line DL1.

[0152] The pixel power line VDDL can be disposed in the non-transmissive region NTA and extend in a second direction (e.g., the Y-axis direction). The pixel power line VDDL can provide a first power supply to the anode electrode 120 of each of the sub-pixels P1, P2, P3 and P4.

[0153] A common power line VSSL can be disposed in the non-transmissive region NTA and extend in a second direction (e.g., the Y-axis direction). The common power line VSSL can provide a second power supply to the cathode electrode 140 of each of the sub-pixels P1, P2, P3, and P4.

[0154] The second repair line RL2 is not set in the second transmission region TA2 and at least a portion of it may overlap with the non-transmission region NTA.

[0155] Specifically, the non-transmissive region NTA may include the light-emitting region EA through which light emitted from each of the sub-pixels P1, P2, P3, and P4 passes to the outside. The black matrix BM may be positioned between the second transmissive region TA2 and the light-emitting region EA to prevent light emitted from each of the multiple sub-pixels P1, P2, P3, and P4 from moving to the second transmissive region TA2.

[0156] like Figure 9 and Figure 10 As shown, at least a portion of the second repair line RL2 may overlap with the black matrix BM. In one embodiment, the boundary between the second repair line RL2 and the second transmission region TA2 may be aligned with or matched with the boundary line BML between the black matrix BM and the second transmission region TA2.

[0157] However, one end of the second repair line RL2 may protrude toward the second transmission region TA2 to reach the first repair contact portion RCNT1, so as to be electrically connected to the fourth anode connection portion ACE4 of the anode connection electrode ACE of a second sub-pixel P2.

[0158] Additionally, the other end of the second repair line RL2 can protrude toward the second transmission region TA2 to reach the welding point WP, so as to overlap with the fourth anode connection portion ACE4 of the anode connection electrode ACE of another second sub-pixel P2.

[0159] In a transparent display panel 110 according to another embodiment of the present disclosure, even if the first repair contact portion RCNT1 and the solder point WP are formed in the second transmissive region TA2, a large portion of the second repair line RL2 can be disposed in the non-transmissive region NTA. Therefore, in the transparent display panel 110 according to another embodiment of the present disclosure, the reduction in the size of the second transmissive region TA2 caused by the second repair line RL2 can be reduced or minimized. That is, in the transparent display panel 110 according to one embodiment of the present disclosure, the degradation of light transmittance caused by the second repair line RL2 can be reduced or minimized.

[0160] The fourth repair line RL4 was not in Figure 9 and Figure 10The details are shown below. However, the fourth repair line RL4 is arranged parallel to the second repair line RL2, with the second transmission region TA2 interposed therebetween. The sub-pixels connected to the fourth repair line RL4 are different from those connected to the second repair line RL2, but essentially the same connection structure or repair process is applied to these repair lines. Therefore, a detailed description of the arrangement of the fourth repair line RL4 will be omitted.

[0161] Figure 11 This is a diagram illustrating an algorithm for applying a signal to a defective subpixel after the repair process.

[0162] Reference Figure 3 and Figure 11 The first repair line RL1 can be positioned between a first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2, and another first sub-pixel P1 connected to the Nth first signal line SL1 and the (M-1)th second signal line SL2. The first repair line RL1 can be positioned in a first-side direction (e.g., to the left of the first sub-pixel P1) connected to the Nth first signal line SL1 and the Mth second signal line SL2. Alternatively, the first repair line RL1 can be positioned in a second-side direction (e.g., to the right of the first sub-pixel P1) connected to the Nth first signal line SL1 and the (M-1)th second signal line SL2.

[0163] N can be an even or odd number greater than zero (0). M can be an even or odd number greater than zero (0). The first signal line SL1 can be a scan line. The second signal line SL2 can be a first data line or a second data line.

[0164] For example, the first repair line RL1 can be set between the first sub-pixel P1 connected to the second line in the first signal line SL1 and the first sub-pixel P1 connected to the second line in the second signal line SL2 and the first line in the second signal line SL2.

[0165] When a defect occurs in the driving transistor, the signal of the first sub-pixel P1 connected to the Nth first signal line SL1 and the (M-1)th second signal line SL2 can be applied to the first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2 through the repair process.

[0166] For example, the repair algorithm can allow signals of Row(n) and Col(m-1) to be applied to the first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2. In this case, n can correspond to the row position of the corresponding sub-pixel, and m can correspond to the column (Col) position of the corresponding sub-pixel.

[0167] The first repair line RL1 can be set in the same direction as the direction in the first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2. In this case, as Figure 11 As shown, the repair algorithm for the first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can be the same as the repair algorithm for the first sub-pixel P1 connected to the (N+1)th first signal line SL1 and the (M+1)th second signal line SL2.

[0168] On the other hand, the first repair line RL1 can be set in a direction different from the direction in the first sub-pixel P1 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the first sub-pixel P1 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2. In this case, as Figure 11 As shown, the first sub-pixel P1 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have a different repair algorithm than the repair algorithm of the first sub-pixel P1 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the first sub-pixel P1 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2.

[0169] The second repair line RL2 can be disposed between the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 and the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2. The second repair line RL2 can also be disposed in the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 in a third-side direction (e.g., a lower direction). Alternatively, the second repair line RL2 can be disposed in the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2 in a fourth-side direction (e.g., an upper direction).

[0170] For example, the second repair line RL2 can be set between the second sub-pixel P2 connected to the second line in the first signal line SL1 and the second line in the second signal line SL2, and the second sub-pixel P2 connected to the third line in the first signal line SL1 and the second line in the second signal line SL2.

[0171] When a defect occurs in the driving transistor, the signal of the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2 is applied to the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 through the repair process.

[0172] For example, the repair algorithm can allow the signals of Row(n+1) and Col(m) to be applied to the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2.

[0173] Furthermore, when a defect occurs in the driving transistor, the signal of the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can be applied to the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2 through the repair process.

[0174] For example, the repair algorithm can allow the signals of Row(n-1) and Col(m) to be applied to the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2.

[0175] Furthermore, the second repair line RL2 can be positioned in the same direction as the direction in the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2. In this case, as... Figure 11 As shown, the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have the same repair algorithm as the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the (M+1)th second signal line SL2.

[0176] On the other hand, the second repair line RL2 can be set in the second sub-pixel P2 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 in a direction different from the direction in the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2. In this case, as Figure 11 As shown, the second sub-pixel P2 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have a different repair algorithm than the repair algorithm of the second sub-pixel P2 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the second sub-pixel P2 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2.

[0177] The third repair line RL3 can be disposed between the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2, and the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2. The third repair line RL3 can also be disposed in the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2 in a second lateral direction (e.g., the right lateral direction). Alternatively, the third repair line RL3 can be disposed in the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 in a first lateral direction (e.g., the left lateral direction).

[0178] For example, the third repair line RL3 can be positioned between the third sub-pixel P3 connected to the second line in the first signal line SL1 and the second line in the second signal line SL2, and the third sub-pixel P3 connected to the second line in the first signal line SL1 and the third line in the second signal line SL2.

[0179] When a defect occurs in the driving transistor, the signal of the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 can be applied to the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2 through the repair process.

[0180] As an example, the repair algorithm can allow the signals of Row(n) and Col(m+1) to be applied to the third sub-pixel P3, which is connected to the Nth first signal line SL1 and the Mth second signal line SL2.

[0181] Furthermore, when a defect occurs in the driving transistor, the signal of the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can be applied to the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 through the repair process.

[0182] As an example, the repair algorithm can allow signals from Row(n) and Col(m-1) to be applied to the third sub-pixel P3, which is connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2.

[0183] Furthermore, the third repair line RL3 can be positioned in the same direction as the direction in the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2. In this case, as... Figure 11As shown, the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have the same repair algorithm as the third sub-pixel P3 connected to the (N+1)th first signal line SL1 and the (M+1)th second signal line SL2.

[0184] On the other hand, the first repair line RL1 can be set in the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 in a different direction than the direction in the third sub-pixel P3 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2. In this case, the third sub-pixel P3 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have a repair algorithm different from the repair algorithm of the third sub-pixel P3 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the third sub-pixel P3 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2.

[0185] The fourth repair line RL4 can be disposed between the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the Mth second signal line SL2, and the fourth sub-pixel P4 connected to the (N-1)th first signal line SL1 and the Mth second signal line SL2. The fourth repair line RL4 can also be disposed in the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the Mth second signal line SL2 in a fourth-side direction (e.g., an upper direction). Alternatively, the fourth repair line RL4 can be disposed in the fourth sub-pixel P4 connected to the (N-1)th first signal line SL1 and the Mth second signal line SL2 in a third-side direction (e.g., a lower direction).

[0186] For example, the fourth repair line RL4 can be positioned between the fourth sub-pixel P4 connected to the second line in the first signal line SL1 and the second line in the second signal line SL2, and the fourth sub-pixel P4 connected to the first line in the first signal line SL1 and the second line in the second signal line SL2.

[0187] When a defect occurs in the driving transistor, the signal of the fourth sub-pixel P4 connected to the (N-1)th first signal line SL1 and the Mth second signal line SL2 can be applied to the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the Mth second signal line SL2 through the repair process.

[0188] For example, the repair algorithm can allow the signals of Row(n-1) and Col(m) to be applied to the fourth sub-pixel P4, which is connected to the Nth first signal line SL1 and the Mth second signal line SL2.

[0189] Furthermore, the fourth repair line RL4 can be positioned in the same direction as the fourth sub-pixel P4 connected to the (N+1)th first signal line SL1 and the (M+1)th second signal line SL2. In this case, as... Figure 11 As shown, the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have the same repair algorithm as the repair algorithm for the fourth sub-pixel P4 connected to the (N+1)th first signal line SL1 and the (M+1)th second signal line SL2.

[0190] On the other hand, the fourth repair line RL4 can be set in a different direction than the direction in the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the fourth sub-pixel P4 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2. In this case, the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the Mth second signal line SL2 can have a repair algorithm different from the repair algorithm of the fourth sub-pixel P4 connected to the Nth first signal line SL1 and the (M+1)th second signal line SL2 and the fourth sub-pixel P4 connected to the (N+1)th first signal line SL1 and the Mth second signal line SL2.

[0191] The following beneficial effects can be obtained from this disclosure.

[0192] In this disclosure, the repair lines are spaced sufficiently apart without overlapping, thereby allowing the repair lines to be formed as straight lines without bypassing the repair contact area. Therefore, this disclosure can reduce or minimize the length of the repair lines and reduce the degradation of light transmittance caused by the repair lines.

[0193] Furthermore, in this disclosure, the repair line is positioned in the non-transmissive region, thereby reducing or minimizing the reduction in the transmissive region caused by the repair line. As a result, this disclosure can minimize the degradation of light transmittance caused by the repair line.

[0194] It will be apparent to those skilled in the art that the present disclosure described above is not limited to the above embodiments and drawings, and various substitutions, modifications, and variations can be made to the present disclosure without departing from the spirit or scope thereof.
