[0003] The present disclosure relates to a transparent display device. Background art

[0004] With the development of the information society, the demand for display devices for displaying images has increased in various forms. In recent years, display devices such as liquid crystal displays (LCDs), organic light - emitting displays (OLEDs), micro - light - emitting diodes (micro - LED displays), and quantum dot displays (QDs) have been utilized.

[0005] Recently, active research has been conducted on transparent displays that not only display images to users but also allow light to pass through to view objects or images located behind the display. The transparent display device includes a display area for displaying an image and a non - display area, and the display area may include a transmissive area that can transmit external light and a non - transmissive area. The transparent display device can have a high light transmittance in the display area through the transmissive area.

[0040] Throughout the drawings and the detailed description, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and / or convenience, the dimensions, lengths, and thicknesses of layers, regions, and elements, and their depictions may be exaggerated. DETAILED DESCRIPTION

[0041] The advantages and features of the present disclosure and the methods for achieving them are elucidated by the embodiments described with reference to the drawings. However, the present disclosure may be implemented in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are examples and are provided so that the present disclosure may be thorough and complete, to assist those skilled in the art in understanding the inventive concept of the present disclosure without limiting the scope of protection of the present disclosure.

[0042] The shapes (e.g., dimensions, lengths, widths, heights, thicknesses, positions, radii, diameters, and areas), dimensions, ratios, angles, quantities, etc. (including those shown in the drawings) disclosed herein are merely examples, and thus, the present disclosure is not limited to the details shown. Any embodiment described herein as an "example" is not necessarily to be construed as preferred or advantageous over other embodiments. However, it should be noted that the relative dimensions of the components shown in the drawings are part of the present disclosure.

[0043] When terms such as "comprising", "having", "including", "containing", "constituting", "made of", "formed by", etc. are used with respect to one or more elements, one or more additional elements may be added unless terms such as "only" are used. The terms used in the present disclosure are only for describing example embodiments and are not intended to limit the scope of the present disclosure. Unless the context clearly indicates otherwise, terms in the singular form may include the plural form.

[0044] When interpreting an element, the element is interpreted as including an error region even though it is not explicitly described.

[0045] When describing positional relationships, for example, when the positional order is described as "on", "above", "below", "beneath", and "next to", cases where there is no contact between them may be included unless "exactly" or "directly" is used.

[0046] If it is mentioned that the first element is positioned "on" the second element, this does not mean that the first element is substantially positioned above the second element in the figure. The upper and lower parts of the object involved may change according to the orientation of the object. Therefore, in the figure or in the actual configuration, the case where the first element is positioned "on" the second element includes the case where the first element is positioned "below" the second element and the case where the first element is positioned "above" the second element.

[0047] When describing temporal relationships, for example, when the temporal order is described as "after", "subsequently", "next", and "before", discontinuous cases may be included unless "exactly" or "directly" is used.

[0048] It should be understood that although terms such as "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element.

[0049] When describing the elements of the present disclosure, terms such as "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended to identify the corresponding elements from other elements, and these terms are not used to define the essence, basis, order, or quantity of the elements.

[0050] For the expressions of an element "connected", "coupled", "attached", "adhered", etc. to another element, the element can not only be directly connected, coupled, attached, adhered, etc. to another element, but also be indirectly connected, coupled, attached, adhered, etc. to another element, with one or more intermediate elements being provided or inserted between the elements, unless otherwise specified.

[0051] For expressions such as an element “contacting” or “overlapping” another element, the element can not only directly contact or overlap another element, but also indirectly contact or overlap another element (with one or more intermediate elements disposed or inserted between the elements), unless otherwise specified.

[0052] The term “at least one” should be understood to include any and all combinations of one or more of the associated listed items. For example, “at least one of the first element, the second element, and the third element” can include two or more elements selected from the first element, the second element, and the third element, as well as all combinations of each of the first element, the second element, and the third element.

[0053] The features of various embodiments of the present disclosure can be partially or fully coupled or combined with each other, can be technically related to each other, and can be operatively interconnected, linked, or driven in various ways. The embodiments of the present disclosure can be implemented or executed independently of each other, or can be implemented or executed together in a mutually dependent or related relationship. In one or more aspects, the components of each device according to various embodiments of the present disclosure are operatively coupled and configured.

[0054] In the following description, various exemplary embodiments of the present disclosure are described in detail with reference to the accompanying drawings. Regarding the reference numerals of the elements of each drawing, the same elements may be shown in other drawings, and unless otherwise specified, the same reference numerals may refer to the same elements. The same or similar elements may be represented by the same reference numerals even if they are shown in different drawings. Additionally, for ease of description, the proportions, dimensions, sizes, and thicknesses of each element shown in the drawings may be different from the actual proportions, dimensions, sizes, and thicknesses. Therefore, the embodiments of the present disclosure are not limited to the proportions, dimensions, sizes, and thicknesses shown in the drawings.

[0055] Figure 1 A transparent display device according to an embodiment of the present disclosure is shown. Figure 2 A circuit diagram of a sub-pixel of a transparent display device according to an embodiment of the present disclosure is shown.

[0056] Hereinafter, the X-axis refers to the direction parallel to the scan line, the Y-axis refers to the direction parallel to the data line, and the Z-axis refers to the height direction of the transparent display device.

[0057] Although a transparent display device according to an embodiment of the present disclosure is described with reference to an organic light-emitting display (OLED), it can also be implemented as a liquid crystal display (LCD), a micro light-emitting diode (micro-LED), a quantum dot (QD) display, etc.

[0058] Refer to Figure 1 andFigure 2 According to an embodiment of the present disclosure, a transparent display device may include a transparent display panel 110, which includes a display area DA having pixels for displaying an image and a non-display area NDA that does not display an image.

[0059] The display area DA of the transparent display panel 110 may include a first signal line SL1, a second signal line SL2, and pixels, and the non-display area NDA may include a pad area PA on which pads are provided and at least one gate driver 205.

[0060] The first signal line SL1 may extend in a first direction (or the Y-axis direction) and may intersect the second signal line SL2 in the display area DA. The second signal line SL2 may extend in a second direction (or the X-axis direction). The pixels may be disposed in an area where the first signal line SL1 and the second signal line SL2 intersect and may emit predetermined light to display an image.

[0061] The gate driver 205 may be connected to scan lines to provide scan signals. The gate driver 205 may be implemented as a gate driver in panel (GIP), or may be implemented as tape automated bonding (TAB) outside one or both sides of the display area DA of the transparent display panel 110.

[0062] The pad area PA of the transparent display panel 110 may be electrically connected to a source driver integrated circuit, a circuit board, a timing controller, etc. connected via a flexible circuit film.

[0063] Reference Figure 2 Each of the pixels may include a plurality of sub-pixels constituting a unit pixel, and each of the plurality of sub-pixels may be equipped with a light-emitting element ED and a circuit element having a 3T1C (3 transistors and 1 capacitor) structure, which includes a first switching transistor TR1, a second switching transistor TR2, a driving transistor DTR, and a capacitor Cst, but is not necessarily limited thereto. Each sub-pixel may further include a compensation circuit and may have various circuit elements, such as 4T2C, 5T2C, 6T1C, 6T2C, 7T1C, 7T2C, etc.

[0064] Each of the transistors (DTR, TR1, TR2) of each sub-pixel may include a gate electrode, a source electrode, and a drain electrode. The source electrode and the drain electrode are not fixed and may change according to the direction of the voltage and current applied to the gate electrode. Thus, one of the source electrode and the drain electrode may be represented as the first electrode, and the other as the second electrode. The transistors DTR, TR1, and TR2 of each sub-pixel may utilize at least one of polysilicon semiconductors, amorphous silicon semiconductors, and oxide semiconductors. The transistors DTR, TR1, and TR2 may be P-type or N-type, or a mixture of P-type and N-type.

[0065] The first switching transistor TR1 may be used to supply the data voltage Vdata provided from the data line DL to the driving transistor DTR. For example, the first switching transistor TR1 may charge the capacitor Cst with the data voltage Vdata provided from the data line DL. For this purpose, the gate electrode of the first switching transistor TR1 may be connected to the scan line SCANL (or gate line), and the first electrode of the first switching transistor TR1 may be connected to the data line DL. In addition, the second electrode of the first switching transistor TR1 may be connected to one terminal of the capacitor Cst and the gate electrode of the driving transistor DTR.

[0066] The first switching transistor TR1 may be turned on in response to the scan signal Scan applied via the scan line SCANL (or gate line). When the first switching transistor TR1 is turned on, the data voltage Vdata applied via the data line DL may be transferred to one terminal of the capacitor Cst.

[0067] The second switching transistor TR2 may be used to supply the reference voltage Vref provided from the reference line REFL to the driving transistor DTR. For example, the gate electrode of the second switching transistor TR may be connected to the scan line SCANL (or gate line), and the first electrode of the second switching transistor TR may be connected to the reference line REFL. In addition, the second electrode of the second switching transistor TR2 may be connected to the first electrode of the driving transistor DTR and the other terminal of the capacitor Cst.

[0068] The second switching transistor TR2 may be turned on in response to the scan signal Scan applied via the scan line SCANL (or gate line). When the second switching transistor TR2 is turned on, the reference voltage Vref applied via the reference line REFL may be transferred to the other terminal of the capacitor Cst. In addition, the reference voltage Vref may also be applied to the source electrode of the driving transistor DTR.

[0069] The capacitor Cst can be used to hold the data voltage Vdata supplied to the driving transistor DTR for one frame. For example, the first electrode of the capacitor Cst can be connected to the gate electrode of the driving transistor DTR, and the second electrode of the capacitor Cst can be connected to the source electrode of the driving transistor DTR. The capacitor Cst can store a voltage corresponding to the data voltage Vdata transmitted via the first switching transistor TR1, and can turn on the driving transistor DTR using the stored voltage.

[0070] The driving transistor DTR can be used to generate a data current from the first power source EVDD supplied from the pixel power supply line VDDL (or the first power supply line) and supply it to the anode electrode of the light-emitting element ED. For example, the gate electrode of the driving transistor DTR can be connected to one terminal of the capacitor Cst, and the first electrode of the driving transistor DTR can be connected to the pixel power supply line VDDL. In addition, the second electrode of the driving transistor DTR can be connected to the anode electrode of the light-emitting element ED.

[0071] The light-emitting element ED can include an anode connected to the driving transistor (DTR), a cathode supplied with a second power source EVSS from the common power supply line VSSL (or the second power supply line), and a light-emitting layer between the anode and the cathode. The anode can be an independent electrode for each light-emitting element, and the cathode can be a common electrode shared by all the light-emitting elements. When a driving current is supplied from the driving transistor DTR, electrons from the cathode are injected into the light-emitting layer, holes from the anode are injected into the light-emitting layer, and the recombination of electrons and holes in the light-emitting layer causes the fluorescent or phosphorescent material to emit light with a brightness proportional to the current value of the driving current.

[0072] The light-emitting element ED can have an anode connected to the second electrode of the driving transistor DTR and a cathode connected to the common power supply line VSSL. The light-emitting element ED can emit light in response to the driving current generated by the driving transistor DTR.

[0073] Figure 3 Illustrated is according to an embodiment of the present disclosure Figure 1 the area A shown in Figure 4 Illustrated is according to an embodiment of the present disclosure Figure 3 the area B shown in

[0074] Refer to Figures 3 to 4 and Figure 1 and Figure 2, the transparent display panel 110 according to an embodiment of the present disclosure may include a display area DA and a non-display area NDA. The display area DA may include a transmissive area TA and a non-transmissive area NTA. The transmissive area TA may be an area that allows most of the light incident from the outside to pass through, and the non-transmissive area NTA may be an area that does not allow most of the light incident from the outside to pass through. For example, the transmissive area TA may be an area having a light transmittance greater than α%, and the non-transmissive area NTA may be an area having a light transmittance less than β%. In this case, α may be a value greater than β. Due to the transmissive area TA, the transparent display panel 110 may allow a user to see an object or a background located behind the transparent display panel 110.

[0075] The non-transmissive area NTA may include a first non-transmissive area NTA1, a second non-transmissive area NTA2, and a pixel P.

[0076] The first non-transmissive area NTA1 extends from the display area DA in a first direction (or the Y-axis direction) and may be arranged to at least partially overlap with the light-emitting areas EA1, EA2, EA3, EA4. The first non-transmissive area NTA1 may include a plurality of first non-transmissive areas. The plurality of first non-transmissive areas NTA1 may extend in the first direction (or the Y-axis direction) and may be spaced apart from each other in a second direction (or the X-axis direction). Two adjacent first non-transmissive areas NTA1 may be spaced apart from each other with a transmissive area TA therebetween. For example, the transmissive area TA may be provided between two adjacent first non-transmissive areas NTA1. The first non-transmissive area NTA1 may be provided with a first signal line SL1 extending in the first direction (or the Y-axis direction). For example, the first signal line SL1 may overlap with the first non-transmissive area NTA1.

[0077] The first signal line SL1 may include at least one of a pixel power supply line VDDL (or a first power supply line), a common power supply line VSSL (or a second power supply line), a reference line REFL, and data lines DL1, DL2, DL3, DL4. For example, the first signal line SL1 may further include a touch sensor line, but embodiments of the present disclosure are not limited thereto.

[0078] The pixel power supply line VDDL (or the first power supply line) may supply a first power source EVDD to a driving transistor DTR of each of the sub-pixels SP1, SP2, SP3, SP4 provided in the display area DA.

[0079] The common power supply line VSSL (or the second power supply line) can supply the second power supply EVSS to the cathodes of the sub-pixels SP1, SP2, SP3, and SP4 provided in the display area DA. In this case, the second power supply EVSS can be a common power supply shared by the sub-pixels SP1, SP2, SP3, and SP4.

[0080] The reference line REFL can supply an initialization voltage (or a reference voltage) to the driving transistors DTR of each of the sub-pixels SP1, SP2, SP3, and SP4 provided in the display area DA. For example, the reference line REFL can be provided between the plurality of data lines DL1, DL2, DL3, and DL4. For example, the reference line REFL can be provided at the center between the plurality of data lines DL1, DL2, DL3, and DL4.

[0081] Each of the data lines DL1, DL2, DL3, and DL4 can supply a data voltage Vdata to the sub-pixels SP1, SP2, SP3, and SP4. For example, the first data line DL1 can supply a first data voltage to the first driving transistor of the first sub-pixel SP1, and the second data line DL2 can supply a second data voltage to the second driving transistor of the second sub-pixel SP2, the third data line DL3 can supply a third data voltage to the third driving transistor of the third sub-pixel SP3, and the fourth data line DL4 can supply a fourth data voltage to the fourth driving transistor of the fourth sub-pixel SP4.

[0082] The second non-transmissive region NTA2 can extend from the display area DA in the second direction (or the X-axis direction), and can be arranged to at least partially overlap with the light-emitting regions EA1, EA2, EA3, and EA4. For example, the second non-transmissive region NTA2 can extend in the second direction (or the X-axis direction) between two adjacent first non-transmissive regions NTA1. The second non-transmissive region NTA2 can include a plurality of second non-transmissive regions. The plurality of second non-transmissive regions NTA2 can extend in the second direction (or the X-axis direction), and can be spaced apart from each other in the first direction (or the Y-axis direction). Two adjacent second non-transmissive regions NTA2 can be spaced apart from each other with a transmissive region TA therebetween. For example, the transmissive region TA can be provided between two adjacent second non-transmissive regions NTA2. The second non-transmissive region NTA2 can be provided with a second signal line SL2 extending in the second direction (or the X-axis direction). For example, the second signal line SL2 can overlap with the second non-transmissive region NTA2.

[0083] The second signal line SL2 extends in the second direction (or the X-axis direction), and can include a scan line SCANL (or a gate line). The scan line SCANL can supply a scan signal to the sub-pixels SP1, SP2, SP3, and SP4 of the pixel P.

[0084] The pixel P can be disposed at each intersection of the first non-transmissive region NTA1 and the second non-transmissive region NTA2, and can emit light to display an image. Each pixel P is disposed between adjacent transmissive regions TA, and the pixel P can include light-emitting regions EA1, EA2, EA3, EA4, and light-emitting elements are disposed in the light-emitting regions EA1, EA2, EA3, EA4 to emit light. The light-emitting regions EA1, EA2, EA3, EA4 can correspond to the regions where light is emitted from the pixel P. Since the transparent display panel 110 has non-transmissive regions NTA with small areas, circuit elements can be arranged to overlap with the light-emitting regions EA1, EA2, EA3, EA4. For example, the light-emitting regions EA1, EA2, EA3, EA4 can at least partially overlap with circuit regions CA1, CA2, CA3, CA4 in which circuit elements are disposed. For example, the circuit regions CA1, CA2, CA3, CA4 can include a first circuit region CA1 in which circuit elements associated with the first sub-pixel SP1 are disposed, a second circuit region CA2 in which circuit elements associated with the second sub-pixel SP2 are disposed, a third circuit region CA3 in which circuit elements associated with the third sub-pixel SP3 are disposed, and a fourth circuit region CA4 in which circuit elements associated with the fourth sub-pixel SP4 are disposed.

[0085] Each pixel P is disposed in the first non-transmissive region NTA1 and can emit light to display an image. Each pixel P can include a first sub-pixel SP1, a second sub-pixel SP2, a third sub-pixel SP3, and a fourth sub-pixel SP4. The first sub-pixel SP1 can include a first light-emitting region EA1 that emits first-color light, the second sub-pixel SP2 can include a second light-emitting region EA2 that emits second-color light, the third sub-pixel SP3 can include a third light-emitting region EA3 that emits third-color light, and the fourth sub-pixel SP4 can include a fourth light-emitting region EA4 that emits fourth-color light. The first to fourth sub-pixels SP1, SP2, SP3, SP4 can be arranged in a matrix in a quadrilateral form along a first direction (or Y-axis direction) and a second direction (or X-axis direction). For example, the first sub-pixel SP1 and the second sub-pixel SP2 can be disposed adjacent to a pixel power line VDDL (or a first power line), and the third sub-pixel SP3 and the fourth sub-pixel SP4 can be disposed adjacent to a common power line VSSL (or a second power line).

[0086] The scan line SCANL can be associated with each of the pixels P corresponding to adjacent horizontal lines. For example, the horizontal lines can indicate that a plurality of pixels P are disposed parallel to each other in the second direction (or X-axis direction). For example, the scan line SCANL can be connected to the pixel P corresponding to the upper horizontal line among two adjacent horizontal lines. For example, the upper horizontal line can be relative toFigure 4 The horizontal line corresponding to the pixel P positioned upward with respect to the pixel P shown. For example, the scan line SCANL (or gate line) may be set to be adjacent to the first sub-pixel SP1 and the third sub-pixel SP3. In addition, the scan line SCANL may be connected to the pixel P corresponding to the lower horizontal line among two adjacent horizontal lines. For example, the lower horizontal line may be the horizontal line corresponding to the pixel P positioned below the pixel P shown in Figure 4 the figure. For example, the scan line SCANL (or gate line) may be set to be adjacent to the second sub-pixel SP2 and the fourth sub-pixel SP4, but embodiments of the present disclosure are not limited thereto. For example, the scan line SCANL may supply different scan signals to the pixel P corresponding to one horizontal line. For example, different scan signals may be supplied to the pixel P corresponding to the horizontal line that Figure 4 corresponds to the pixel P shown in the figure.

[0087] The first to fourth light-emitting regions EA1, EA2, EA3, EA4 may all emit light of different colors. For example, the first light-emitting region EA1 may emit green light, the second light-emitting region EA2 may emit blue light, the third light-emitting region EA3 may emit white light, and the fourth light-emitting region EA4 may emit red light, but embodiments of the present disclosure are not limited thereto. For example, the arrangement order or arrangement form of each of the sub-pixels SP1, SP2, SP3, SP4 may be changed.

[0088] The transparent display panel 110 according to an embodiment of the present disclosure may include a plurality of light-emitting regions EA1, EA2, EA3, EA4 included in each of a plurality of sub-pixels SP1, SP2, SP3, SP4. For example, each of the plurality of sub-pixels SP1, SP2, SP3, SP4 may have a first electrode 120 (or an anode electrode) of a light-emitting element, and the first electrode 120 includes a first separated electrode 121 and a second separated electrode 122 spaced apart from each other. Each of the first separated electrode 121 and the second separated electrode 122 may correspond to a separate light-emitting region. For example, the first light-emitting region EA1 provided in the first sub-pixel SP1 may include a first divided light-emitting region EA11 corresponding to the first separated electrode 121 and a second divided light-emitting region EA12 corresponding to the second separated electrode 122. The second light-emitting region EA2 provided in the second sub-pixel SP2 may include a first divided light-emitting region EA21 corresponding to the first separated electrode 121 and a second divided light-emitting region EA22 corresponding to the second separated electrode 122. The third light-emitting region EA3 provided in the third sub-pixel SP3 may include a first divided light-emitting region EA31 corresponding to the first separated electrode 121 and a second divided light-emitting region EA32 corresponding to the second separated electrode 122. The fourth light-emitting region EA4 provided in the fourth sub-pixel SP4 may include a first divided light-emitting region EA41 corresponding to the first separated electrode 121 and a second divided light-emitting region EA42 corresponding to the second separated electrode 122.

[0089] The first separated electrode 121 and the second separated electrode 122 may be electrically coupled to each other via a repair pattern RP. The repair pattern RP may be used to repair the darkening of either the first separated electrode 121 or the second separated electrode 122. For example, the repair pattern RP may electrically connect the first separated electrode 121 and the second separated electrode 122 to the circuit regions CA1, CA2, CA3, CA4 of each sub-pixel SP1, SP2, SP3, SP4. For example, the repair pattern RP may be organized in a "T" shape. One end of the repair pattern RP may bifurcate and be electrically connected to each of the first separated electrode 121 and the second separated electrode 122, and the other end of the repair pattern RP may be electrically connected to the circuit regions CA1, CA2, CA3, CA4 of each of the sub-pixels SP1, SP2, SP3, SP4. When a foreign object is disposed on either the first separated electrode 121 or the second separated electrode 122, the repair pattern RP may be used to disconnect the electrical connection between the separated electrode having the foreign object thereon and the circuit region, so that only the separated electrode having the foreign object thereon is darkened and the remaining separated electrodes are repaired to normal operation.

[0092] The at least one trench line TCL may be used to cut off the light-emitting layer (or organic light-emitting layer) formed in the transmissive region TA. The at least one trench line TCL may include a part of at least one protective layer (e.g., a planarization layer and a passivation layer). For example, the at least one trench line TCL may be formed by removing at least a part of the at least one protective layer (e.g., the planarization layer and the passivation layer). Below the at least one trench line TCL, a scan line SCANL (or gate line) spanning the transmissive region TA may be provided. The intersection of the at least one trench line TCL and the scan line SCANL may further include a block pattern BP. For example, the block pattern BP may prevent damage to the scan line SCANL intersecting the at least one trench line TCL below the at least one trench line TCL during the process of forming the at least one trench line TCL.

[0093] The at least one trench line TCL may be arranged adjacent to the common power supply line VSSL in the transmissive region TA. For example, the at least one trench line TCL may cut off the light-emitting layer (or organic light-emitting layer) corresponding to the common power supply line VSSL extending from the pixel P. For example, the at least one trench line TCL may be formed by removing at least a part of the at least one protective layer (e.g., the planarization layer and the passivation layer). For example, the at least one protective layer may include an organic insulating layer, and the at least one trench line TCL may be formed by removing at least a part of the organic insulating layer so as to cut off or disconnect the organic insulating layer. Thus, moisture can be prevented from penetrating from the outside of the at least one trench line TCL toward the pixel (P). Therefore, a specific region including the transmissive region TA located outside the at least one trench line TCL may be cut by a cutting device such as a laser or a wheel, and moisture can be prevented from penetrating from the outside of the at least one trench line TCL.

[0094] The transparent display panel 110 according to an embodiment of the present disclosure may further include an auxiliary power contact portion AXC disposed in the transmissive region TA and in contact with the second electrode (or cathode, common electrode) of the light-emitting element ED.

In addition, at least one of the data line DL of the first signal line, the pixel power supply line VDDL, the common power supply line VSSL, and the reference line REFL can be disposed on the buffer layer BF, but embodiments of the present disclosure are not limited thereto. Further, on the buffer layer BF, the scan line SCANL (or gate line) as the second signal line can be disposed in the non-transmission region NTA and the transmission region TA. For example, at least a part of the scan line SCANL can be disposed to extend in the second direction (or X-axis direction) to straddle the transmission region TA.

[0103] The auxiliary power supply contact portion AXC can be formed of the same material in the same layer as the auxiliary power supply line AXL. For example, the auxiliary power supply contact portion AXC can be integrally formed with the auxiliary power supply line AXL. For example, the auxiliary power supply contact portion AXC can be formed by extending the region of the auxiliary power supply line AXL overlapping at least one trench line TCL. The auxiliary power supply contact portion AXC can be formed of a different material in a layer different from the auxiliary power supply line AXL. For example, at least one insulating layer can be disposed between the auxiliary power supply contact portion AXC and the auxiliary power supply line AXL, and the auxiliary power supply contact portion AXC and the auxiliary power supply line AXL can be electrically connected to each other through a contact hole penetrating at least one insulating layer, but embodiments of the present disclosure are not limited thereto.

[0104] The interlayer dielectric layer ILD can be disposed on the substrate 111 on which the auxiliary power supply line AXL and the auxiliary power supply contact portion AXC are disposed.

The ILD can include a single layer or multiple layers including an inorganic insulating material such as silicon oxide (SiOx), silicon nitride (SiNx), or aluminum oxide (Al2O3).

At least one of the data line DL, the pixel power supply line VDDL, the common power supply line VSSL, and the reference line REFL of the first signal line may be disposed on the first passivation layer PAS1, but the embodiments herein are not limited thereto.

[0106] The planarization layer PLN may be disposed on the second passivation layer PAS2 to planarize the steps caused by the thin film transistors and the plurality of signal lines. The planarization layer PLN may be formed of an organic material such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, etc.

[0107] The light-emitting element ED including the first electrode 120, the organic light-emitting layer 130, and the second electrode 140 and the bank layer BA may be disposed on the planarization layer PLN.

[0108] The first electrode 120 is disposed at each sub-pixel SP1, SP2, SP3, SP4 and may be disposed in the non-transmissive region NTA.

[0110] The organic light-emitting layer 130 may be disposed on the first electrode 120. The organic light-emitting layer 130 may include a hole transport layer, a light-emitting material layer, and an electron transport layer. For example, when a voltage is applied to the first electrode 120 and the second electrode 140, holes and electrons migrate to the organic light-emitting layer 130 through the hole transport layer and the electron transport layer, respectively, and may combine with each other in the light-emitting material layer to emit light. The organic light-emitting layer 130 may be separated or disconnected by a plurality of trench lines TCL and undercut lines UCL.

[0111] The second electrode 140 may be a common layer shared by sub-pixels SP1, SP2, SP3, and SP4 to which the same voltage is applied. The second electrode 140 may be formed of a transparent conductive material (TCO), such as ITO or IZO, which can transmit light, or formed of a semi-transmissive conductive material, such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). If the second electrode 140 is formed of a semi-transmissive conductive material, the light-emitting efficiency may be improved by a microcavity. The second electrode 140 may be the cathode of the light-emitting element ED.

[0112] The encapsulation layer EPAS may be disposed on the light-emitting element ED. The encapsulation layer EPAS may be configured to cover the second electrode 140 above the second electrode 140. The encapsulation layer EPAS may be used to prevent oxygen or moisture from penetrating the organic light-emitting layer 130 and the second electrode 140. For example, the encapsulation layer EPAS may include at least one inorganic film and may also include at least one organic film, but the embodiments herein are not limited thereto.

[0113] The transparent display device 110 according to an embodiment of the present disclosure may include a plurality of trench lines TCL1, TCL2 and undercut lines UCL using a planarization layer PLN and at least one insulating layer (e.g., an interlayer dielectric layer ILD, a first passivation layer PAS1, a second passivation layer PAS2). For example, a plurality of trench lines TCL1, TCL2 may be formed by removing at least a part of at least one insulating layer.

[0114] The plurality of trench lines TCL1, TCL2 may be disposed parallel to each other in a first direction (or Y-axis direction) and spaced apart from each other in a second direction (or X-axis direction). A plurality of trench lines TCL1, TCL2 may be formed by removing at least one insulating layer on the buffer layer BF. A plurality of trench lines TCL1, TCL2 may be formed by removing the interlayer dielectric layer ILD, the first passivation layer PAS1, and the second passivation layer PAS2.

[0115] The bottom tangent UCL can be set between multiple trench lines TCL1 and TCL2. The bottom tangent UCL can be formed by removing at least a portion of the planarization layer PLN and at least one insulating layer. The bottom tangent UCL can include a support line UCL1 and an eaves line UCL2. The support line UCL1 includes at least one insulating layer. The eaves line UCL2 is located on the support line UCL1 and protrudes from the support line UCL1, and includes the planarization layer PLN. The bottom tangent UCL can include a bottom cut area UCA having multiple trench lines TCL1 and TCL2. For example, the bottom tangent UCL can have a bottom cut area UCA including the lower edge of the eaves line UCL2 and one side of the support line UCL1. For example, the bottom cut area UCA can be included in the multiple trench lines TCL. The bottom tangent UCL and the multiple trench lines TCL can be set adjacent to the common power supply line VSSL. In addition, the bottom tangent UCL and the multiple trench lines TCL can be set not to overlap with the repair pattern RP.

[0116] The bottom tangent UCL and the multiple trench lines TCL can be set above a portion of the auxiliary power contact AXC, as Figure 7 shown. The bottom tangent UCL and the multiple trench lines TCL can be configured to expose a portion of the auxiliary power contact AXC. For example, a portion of the auxiliary power contact AXC can be exposed by at least one trench line TCL. The exposed portion of the auxiliary power contact AXC can be in direct contact with and electrically connected to the second electrode (or cathode) of the light-emitting element ED.

[0117] Below the bottom tangent UCL and the multiple trench lines TCL, a scan line SCANL (or gate line) spanning the transmission area TA can be arranged. At the intersection of the bottom tangent UCL / multiple trench lines TCL and the scan line SCANL, a block pattern BP can be provided. For example, the block pattern BP can be formed at the intersection of the bottom tangent UCL / multiple trench lines TCL and the scan line SCANL.

[0118] The block pattern BP is intended to prevent damage to the scan line SCANL by the etchant used when forming the bottom tangent UCL and the multiple trench lines TCL. For example, the block pattern BP can be formed between the bottom tangent UCL and the scan line SCANL. The block pattern BP can be formed on the first passivation layer PAS1. For example, the block pattern BP can be formed of the same material as other signal lines formed on the first passivation layer PAS1. For example, the block pattern BP can be formed of the same material in the same layer as at least one of the data line DL, pixel power supply line VDDL, common power supply line VSSL, and reference line REFL of the first signal line. Alternatively, the block pattern BP can be formed of the same material in the same layer as at least one of the auxiliary power supply line AXL and the auxiliary power contact AXC, but the embodiments of the present disclosure are not limited thereto.

[0119] The bottom cut line UCL and multiple trench lines TCL can be arranged adjacent to the common power supply line VSSL, and can cut off the light-emitting layer (or organic light-emitting layer) extending from the pixels (P) corresponding to the adjacent common power supply line VSSL. In addition, by removing at least a part of the planarization layer PLN which is an organic material, the organic insulating layer can be cut to form the bottom cut line UCL. Thus, the bottom cut line UCL and multiple trench lines TCL can cut off the organic light-emitting layer and the organic insulating layer of the transparent display panel 11 in the first direction (or Y-axis direction), and prevent moisture from entering the transmissive area TA or the border. Therefore, even if a certain area including the transmissive area TA outside the bottom cut line UCL and multiple trench lines TCL is cut by a cutting device such as a laser or a wheel, moisture penetration from the outside can be prevented by the bottom cut line UCL and multiple trench lines TCL.

[0120] By configuring the transparent display panel 110 according to an embodiment of the present disclosure with the bottom cut line UCL and multiple trench lines TCL extending in the first direction (or Y-axis direction) within the transmissive area TA and overlapping with the auxiliary power supply contact portion AXC, the space of the transmissive area TA can be shared with the auxiliary power supply contact structure, thereby further ensuring the edge of the transmissive area TA and improving the light transmittance of the transparent display panel 110. In addition, the transparent display panel 110 according to an embodiment of the present disclosure can prevent moisture from penetrating from the transmissive area TA or the border through the bottom cut line UCL and multiple trench lines TCL. Thus, the outside of the boundary line of the bottom cut line UCL and multiple trench lines TCL can be a cuttable area, and even if it is cut (or separated), this cuttable area can prevent moisture from penetrating towards the pixels (P). Therefore, by providing a cuttable area in the transmissive area TA by the bottom cut line UCL and multiple trench lines TCL, the transparent display panel 110 according to the embodiment of the present disclosure can implement or realize a cuttable transparent display panel, which can be divided into various sizes according to the fields and uses to which the transparent display panel 110 is applied.

In the following description, the same reference numerals are given to the same configurations except for the modified configuration, and redundant descriptions are omitted or abbreviated. Figures 1 to 8

[0122] Reference Figures 9 to 13 , the transparent display panel 110 according to other embodiments of the present disclosure may include trench lines TCL extending in a first direction (or Y-axis direction) in a transmissive region TA and auxiliary power contact portions AXC overlapping at least a part of the trench lines TCL.

[0123] A common power supply line VSSL in the first signal lines may be provided on the substrate 111. For example, at least one of a data line DL, a pixel power supply line VDDL, a common power supply line VSSL, and a reference line REFL formed of the same material in the same layer as the light-shielding layer may be provided on the substrate 111, but embodiments of the present disclosure are not limited thereto.

[0124] At least one insulating layer may be sequentially provided on the substrate 111. For example, the at least one insulating layer may include a buffer layer BF, an interlayer dielectric layer ILD, a first passivation layer PAS1, and a second passivation layer PAS2.

[0125] A planarization layer PLN may be provided on the second passivation layer PAS2 to planarize steps caused by thin film transistors and multiple signal lines. On the planarization layer PLN, a light-emitting element (ED) including a first electrode 120, an organic light-emitting layer 130, and a second electrode 140 and a bank layer BA may be provided.

[0126] The organic light-emitting layer 130 and the second electrode 140 of the light-emitting element (ED) extending into the transmissive region TA may be arranged in the transparent display panel 110 according to other embodiments of the present disclosure. The organic light-emitting layer 130 provided in the transmissive region TA may be cut or disconnected by at least one trench line TCL.

[0127] At least one trench line TCL may be formed by removing at least a part of the organic light-emitting layer 130 provided in the transmissive region TA. For example, at least one trench line TCL may be configured by irradiating the transmissive region TA on the substrate 111 with a laser along the first direction (or Y-axis direction) after the formation of the organic light-emitting layer 130 is completed during the manufacturing process of the transparent display panel 110, and linearly cutting or disconnecting the organic light-emitting layer 130 by laser irradiation. For example, the organic light-emitting layer 130 may not exist in at least one trench line TCL. For example, at least one trench line may be formed by a laser drilling process, but embodiments herein are not limited thereto.

[0128] At least one trench line TCL can be configured to pass through the auxiliary power contact AXC. For example, the auxiliary power contact AXC can be disposed in the transmissive region TA. The auxiliary power contact AXC can include a plurality of auxiliary power contacts AXC, and the plurality of auxiliary power contacts AXC can be disposed parallel to each other in the first direction (or Y-axis direction). At least one trench line TCL can be configured by removing the organic light-emitting layer 130 along the first direction (or Y-axis direction) to overlap with the plurality of auxiliary power contacts AXC disposed parallel to each other. At least one trench line TCL can expose a part of the auxiliary power contact AXC to the outside by removing the organic light-emitting layer 130 on the auxiliary power contact AXC.

[0129] During the manufacturing process of the transparent display panel 110, after the formation of at least one trench line TCL is completed, the second electrode 140 can be formed, and the second electrode 140 can be in direct contact with the auxiliary power contact AXC exposed by at least one trench line TCL.

[0130] The auxiliary power contact AXC can be disposed on the first passivation layer PAS1, as Figure 11 shown. The auxiliary power contact AXC can be connected to the common power supply line VSSL, connected to the auxiliary power supply line AXL extending in the second direction (or X-axis direction), or can be formed of the same material in the same layer as the auxiliary power supply line AXL. For example, the auxiliary power contact AXC can be integrally formed with the auxiliary power supply line AXL. The auxiliary power contact AXC can be integrated with or connected to the auxiliary power supply line AXL to apply the second power supply (or common voltage or low potential voltage) provided from the common power supply line EVSS to the second electrode 140. The auxiliary power contact AXC can have a portion exposed to at least one trench line TCL and in direct contact with the second electrode 140 to reduce the resistance of the second electrode 140.

[0131] The auxiliary power contact AXC can be disposed in the second passivation layer PAS2, as Figure 12As shown. The auxiliary power contact portion AXC can be formed of a different material in a layer different from the auxiliary power supply line AXL. For example, the auxiliary power contact portion AXC can be formed of the same material as the first electrode 120. The auxiliary power contact portion AXC can be electrically connected to the auxiliary power supply line AXL through a contact hole that penetrates and inserts into the second passivation layer PAS2 between the auxiliary power supply line AXL and the auxiliary power contact portion AXC. The auxiliary power contact portion AXC can be integrated with or connected to the auxiliary power supply line AXL, and can be used to apply a second power supply (or common voltage or low potential voltage) provided from the common power supply line EVSS to the second electrode 140. The auxiliary power contact portion AXC can have a portion exposed to at least one trench line TCL and in direct contact with the second electrode 140 to reduce the resistance of the second electrode 140.

[0132] The block pattern BP can be provided at the intersection of at least one trench line TCL and the scan line SCANL. For example, as Figure 13 shown, the block pattern BP can be provided on the first passivation layer PAS1. The block pattern BP is designed to prevent the scan line SCANL from being damaged by laser when forming at least one trench line TCL. For example, the block pattern BP can be provided between the trench line TCL and the scan line SCANL. For example, the block pattern BP can be composed of the same material in the same layer as at least one of the auxiliary power supply line AXL and the auxiliary power contact portion AXC formed on the first passivation layer PAS1. For example, the block pattern BP can be formed of the same material in the same layer as at least one of the data line DL, pixel power supply line VDDL, common power supply line VSSL, and reference line REFL of the first signal line, but the embodiments of the present disclosure are not limited thereto.

[0133] According to other embodiments of the present disclosure, the block pattern BP can be omitted. A plurality of insulating layers can be provided between at least one trench line TCL and the scan line SCANL. For example, the interlayer dielectric layer ILD, the first passivation layer PAS1, and the second passivation layer PAS2 can be provided between at least one trench line TCL and the scan line SCAN1. Thus, during the process of forming at least one trench line TCL by laser irradiation, the scan line SCANL will not be damaged, so the block pattern BP can be omitted.

[0134] According to other embodiments of the present disclosure, at least one trench line TCL may be formed by removing at least a portion of the organic light emitting layer 130 and the second electrode 140 disposed in the transmissive region TA. For example, during the manufacturing process of the transparent display panel 110, after the formation of the organic light emitting layer 130 and the second electrode 140 is completed, the transmissive region TA on the substrate 111 may be irradiated with a laser along the first direction (or Y-axis direction), and at least one trench line TCL may be configured by linearly cutting or disconnecting the organic light emitting layer 130 and the second electrode 140 through the laser irradiation. For example, the organic light emitting layer 130 and the second electrode 140 may not exist in at least one trench line TCL. For example, at least one trench line (TCL) may be formed by a laser drilling process, but embodiments of the present disclosure are not limited thereto.

[0135] According to other embodiments of the present disclosure, at least one trench line TCL may include a plurality of trench lines TCL that are parallel to each other in the first direction (or Y-axis direction) and spaced apart from each other in the second direction (or X-axis direction) in the transmissive region TA. The plurality of trench lines TCL may be provided in multiple numbers in the transmissive region TA to further prevent external moisture from penetrating.

[0136] By configuring the transparent display panel 110 according to other embodiments of the present disclosure with a trench line TCL that extends in the first direction (or Y-axis direction) within the transmissive region TA and overlaps with the auxiliary power contact portion AXC, the space of the transmissive region TA may be shared with the auxiliary power contact structure while minimizing the removal region of the organic light emitting layer 130, thereby further securing the edge of the transmissive region TA and improving the light transmittance of the transparent display panel 110. In addition, the transparent display panel 110 according to other embodiments of the present disclosure may prevent moisture from penetrating from the transmissive region TA or the border through at least one trench line TCL.
