[0025] Throughout the accompanying drawings and detailed description, unless otherwise stated, the same reference numerals shall be construed as referring to the same elements, features, and structures. For clarity, illustration, and convenience, the relative sizes and depictions of these elements may be exaggerated. Detailed Implementation

[0026] Reference will now be made in detail to exemplary embodiments of this disclosure, examples or aspects of which may be illustrated in the accompanying drawings. In the following description, unless otherwise stated, the structures, implementations, methods, and operations described herein are not limited to the specific examples, aspects, and embodiments set forth herein, and may be modified as is known in the art. Unless otherwise stated, the same reference numerals always denote the same elements. The names of the elements used in the following description are chosen solely for ease of writing and may therefore differ from those used in actual products. The advantages and features of this disclosure and its implementation methods will be illustrated by the following exemplary embodiments described with reference to the accompanying drawings. However, this disclosure may be implemented in different forms and should not be construed as limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided, in contrast, to make this disclosure sufficiently thorough and complete to assist those skilled in the art in fully understanding its scope. Furthermore, the scope of protection of this disclosure is defined by the claims and their equivalents. In the following description, detailed descriptions of relevant known functions or configurations may be omitted where such detailed descriptions may unnecessarily obscure aspects of this disclosure. The shapes, sizes, ratios, angles, quantities, etc., illustrated in the drawings to describe various exemplary embodiments of this disclosure are given by way of example only. Therefore, this disclosure is not limited to the illustrations in the figures. Unless used with the term “only,” the terms “comprising,” “having,” “including,” “constituting,” “made of,” and “formed from” as used herein are generally intended to allow for the addition of other components. As used herein, the singular forms are intended to include the plural forms unless the context clearly indicates otherwise.

[0027] Although the terms “first,” “second,” A, B, (a), (b), etc., may be used herein to describe various elements, these elements should not be construed as being limited by these terms, as they are not used to define a particular order or priority. 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.

[0028] When it is mentioned that the first element is "connected or linked to" the second element, "in contact" with the second element, or "overlaps" with the second element, it should be understood that not only can the first element be "directly connected or linked to" the second element, "directly in contact" with the second element, or "directly overlap" with the second element, but also that the third element can be "inserted" between the first and second elements, or that the first and second elements can be "connected or linked to," "in contact," or "overlap" with each other via a fourth element. Here, the second element can be included in at least one of two or more elements that are "connected or linked," "in contact," or "overlap" with each other.

[0029] When describing positional relationships, such as when using terms like "above," "over," "below," "on top," "beside," or "adjacent" to describe the positional relationship between two components, one or more other components may be located between the two components unless more restrictive terms such as "immediately," "directly," or "nearly" are used. For example, if an element or layer is positioned "above" another element or layer, a third element or layer may be inserted therebetween. Furthermore, the terms "left," "right," "above," "below," "downward," "upward," "upper part," "lower part," etc., refer to any frame of reference.

[0030] Furthermore, when referring to any size, relative size, etc., even without a specified description, it should be assumed that the numerical values ​​or corresponding information of the component or feature (e.g., level, range, etc.) include the tolerances or error ranges that may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). Moreover, the term "may" fully encompasses all the meanings of the term "may".

[0031] In the following description, various exemplary aspects of this disclosure are described in detail with reference to the accompanying drawings. Unless otherwise stated, the same reference numerals may be used to indicate the same elements in other drawings, and the same reference numerals may refer to the same elements. Even when depicted in different drawings, the same or similar elements may be represented by the same reference numerals. Furthermore, for ease of description, the scale, dimensions, size, and thickness of each element shown in the drawings may differ from the actual scale, dimensions, size, and thickness, and therefore, aspects of this disclosure are not limited to the scale, dimensions, size, and thickness shown in the drawings.

[0032] The expressions "first element," "second element," and " / or" "third element" should be understood as one of the first element, the second element, and the third element, or any or all combinations of the first element, the second element, and the third element. For example, A, B, and / or C can refer to only A; only B; only C; any or some combinations of A, B, and C; or all of A, B, and C.

[0033] The term “at least one” should be understood to include any and all combinations of one or more associated listed items. For example, “at least one of the first element, the second element, and the third element” means a combination of all three listed elements, a combination of any two of the three elements, and each individual element (the first element, the second element, or the third element).

[0034] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments pertain. It should also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with, for example, their meaning in the context of the relevant field, and should not be interpreted in an idealized or overly formal sense unless explicitly defined herein. For example, as one of ordinary skill in the art will understand, the terms “component” or “unit” can be applied to, for example, a single circuit or structure, an integrated circuit, a computational block of a circuit device, or any structure configured to perform the described functions.

[0035] Figure 1 This is an example of the system configuration of a touch display device 100 according to aspects of this disclosure.

[0036] Reference Figure 1 The touch display device 100 may include a display panel 110, which defines a display area AA that allows multiple sub-pixels SP to be set and a non-display area NA located outside the display area AA.

[0037] The touch display device 100 may include a gating drive circuit 120, a data drive circuit 130, and a controller 140 for driving multiple signal lines disposed in the display panel 110.

[0038] Multiple gate lines GL and multiple data lines DL can be set in the display panel 110, and the corresponding sub-pixels SP can be set in each area where the gate lines GL and data lines DL intersect.

[0039] The gating drive circuit 120 can be controlled by the controller 140, and the driving time of multiple sub-pixels SP can be controlled by sequentially outputting gating signals to multiple gating lines GL set in the display panel 110.

[0040] For example, the gating drive circuit 120 can output at least one of the first scan gating signal, the second scan gating signal, and the light emission control gating signal to each of the plurality of sub-pixels SP.

[0041] The gating drive circuit 120 may include one or more gating driver integrated circuits (GDICs). Depending on design requirements, the gating drive circuit 120 may be located on one or both or more sides of the display panel 110.

[0042] Each gate driver integrated circuit (GDIC) can be connected to a pad of the display panel 110 via tape-on-board (TAB) or chip-on-glass (COG) technology, or it can be disposed within the display panel 110 via gate-in-panel (GIP) technology. In one or more embodiments, each gate driver integrated circuit (GDIC) can be configured such that it is integrated into the display panel 110. In one or more aspects, each gate driver integrated circuit (GDIC) can be mounted on a film connected to the display panel 110 via chip-on-film (COF) technology.

[0043] In one or more embodiments, the gating drive circuit 120 may include a plurality of stages corresponding to a plurality of gating lines GL, and each of the plurality of stages may include at least one scan driver and at least one light emission control driver.

[0044] For example, the gating drive circuit 120 may include at least one first scan driver configured to provide a first scan gating signal, at least one second scan driver configured to provide a second scan gating signal, and at least one light emission control driver configured to provide a light emission control gating signal.

[0045] The data driving circuit 130 can receive image data DATA from the controller 140 and convert the image data DATA into analog data voltage. The data driving circuit 130 can output a corresponding data voltage to each data line DL according to the time when the scan signal is applied through the gate line GL, thereby causing the corresponding sub-pixel SP to emit light according to the brightness of the image data DATA.

[0046] The data drive circuit 130 may include one or more source driver integrated circuits (SDICs).

[0047] Each source driver integrated circuit (SDIC) may include a shift register, latch circuit, digital-to-analog converter, output buffer, etc.

[0048] Each source driver integrated circuit (SDIC) can be connected to the bonding pads of the display panel 110 via tape-on-board (TAB) or chip-on-glass (COG) technology, or it can be placed directly on the display panel 110. In one or more aspects, each source driver integrated circuit (SDIC) can be configured to be integrated into the display panel 110. In one or more aspects, each source driver integrated circuit (SDIC) can be implemented using chip-on-film (COF) technology. In this implementation, each source driver integrated circuit (SDIC) can be mounted on a film connected to the display panel 110 and connected to the display panel 110 via wires on the film.

[0049] The controller 140 can provide several control signals to the gating drive circuit 120 and the data drive circuit (130), and can control the operation of the gating drive circuit 120 and the data drive circuit 130.

[0050] The controller 140 can be mounted on a printed circuit board or flexible printed circuit and is electrically connected to the gating drive circuit 120 and the data drive circuit 130 via the printed circuit board or flexible printed circuit.

[0051] The controller 140 can cause the gating drive circuit 120 to output a gating signal based on the establishment time in each frame. The controller 140 can convert image data received from external devices or systems into a data signal form that can be read by the data drive circuit 130, and output the resulting image data to the data drive circuit 130.

[0052] In addition to image data, the controller 140 can also receive several types of timing signals from external devices or systems (e.g., host systems), including vertical synchronization signal Vsync, horizontal synchronization signal Hsync, input data enable (DE) signal, clock signal CLK, etc.

[0053] The controller 140 can use timing signals received from external devices or systems (e.g., host systems) to generate several control signals (DCS, GCS) and output the generated control signals (DCS, GCS) to the gating drive circuit 120 and the data drive circuit 130.

[0054] For example, in order to control the gating drive circuit 120, the controller 140 can output multiple gating control signals GCS to the gating drive circuit 120, including gating start pulse (GSP), gating shift clock (GSC), gating output enable signal (GOE), etc.

[0055] For example, in order to control the data drive circuit 130, the controller 140 can output several data control signals DCS to the data drive circuit 130, including the source start pulse (SSP), the source sampling clock (SSC), the source output enable signal (SOE), etc.

[0056] The touch display device 100 may include a power management integrated circuit for providing various voltages or currents to the display panel 110, the gating drive circuit 120 and the data drive circuit 130, or for controlling the various voltages or currents to be provided.

[0057] In one or more embodiments, liquid crystal or light-emitting elements may be disposed in each sub-pixel SP, depending on the type of display panel 110. In one or more embodiments, electrodes for which data voltage is applied and electrodes for which a common voltage is applied may be disposed in each or one or more sub-pixels SP in the display panel 110.

[0058] In one or more embodiments, the touch display device 100 may include a touch sensor, wiring, and at least one driving circuit for sensing a user's touch on the display panel 110.

[0059] For example, the touch display device 100 may include a plurality of touch electrodes TE located in the display area AA, a touch driving circuit 150 for driving the touch electrodes TE, and a plurality of touch lines TL for connecting the touch electrodes TE and the touch driving circuit 150. In one or more embodiments, the touch display device 100 may include a touch controller 160 for controlling the touch driving circuit 150 and detecting touch based on signals or data detected by the touch driving circuit 150.

[0060] The touch electrode TE can be set on the display panel 110 or embedded in the display panel 110.

[0061] In the example where the touch electrode TE is embedded in the display panel 110, the structure of the touch electrode TE in the display panel 110 can vary depending on the type of touch display device 100.

[0062] In one or more embodiments, in an example where the touch display device 100 has a top light-emitting structure, the touch electrode TE may be disposed on an encapsulation component configured to protect one or more light-emitting elements of the display panel 110.

[0063] In one or more embodiments, in an example where the touch display device 100 has a bottom emitting structure, the touch electrode TE may be disposed between a layer in which one or more light-emitting elements are disposed and a substrate.

[0064] In one or more embodiments, the touch electrode TE can be formed by using a portion of at least one electrode layer included in one or more light-emitting elements in the display panel 110.

[0065] In this implementation, at least one electrode layer included in one or more light-emitting elements can provide the functions of electrodes for display driving and electrodes for touch sensing. In one or more aspects, the electrode layer for display driving and the electrode layer for touch sensing can be located in the same layer while being arranged spaced apart from each other.

[0066] For example, the touch electrode TE can be a transparent electrode or an opaque electrode in which one or more of its portions are open.

[0067] For example, a touch electrode TE formed with an opening portion can be a touch electrode TE configured to include a grid with one or more openings. The opening portion of the touch electrode TE can overlap with the light-emitting areas respectively disposed in the sub-pixel SP.

[0068] In one or more embodiments, depending on the structure in which the touch electrodes TE are disposed and the method of touch sensing therein, the touch line TL can be configured such that a corresponding touch line TL can be connected to each touch electrode TE, or a touch line TL can be connected to multiple touch electrodes TE.

[0069] For example, such as Figure 1 As shown, multiple touch electrodes TE can be arranged separately from each other, and corresponding touch lines TL can be electrically connected to each touch electrode TE.

[0070] In this example, multiple touch electrodes TE can be disposed in the same layer. In one or more embodiments, multiple touch lines TL can be disposed in a different layer than the layer where the touch electrodes TE are disposed. Each of the multiple touch lines TL can be electrically connected to a corresponding one of the multiple touch electrodes TE. A portion of the touch line TL can overlap with a touch electrode TE that is not electrically connected to the touch line TL.

[0071] For example, a touch drive signal can be provided to the touch electrode TE via the touch line TL, and a touch can be sensed by detecting a change in self-capacitance detected via the touch line TL.

[0072] In another example, the plurality of touch electrodes TE may include a plurality of touch electrodes TE connected in a first direction and a plurality of touch electrodes TE connected in a second direction. A touch line TL may be configured such that a touch line TL is electrically connected to a touch electrode TE connected in the first direction, and another touch line TL is electrically connected to a touch electrode TE connected in the second direction.

[0073] In this implementation, multiple touch electrodes TE can be arranged in the same layer, or, according to design requirements, some of the touch electrodes TE can be connected by at least one connecting line arranged in the same layer as the touch electrodes TE, and the remaining touch electrodes TE can be connected by at least one connecting line arranged in a different layer from the touch electrodes TE.

[0074] For example, the first direction can be a column direction (i.e., the Y-axis direction), and the second direction can be a row direction (i.e., the X-axis direction), but this disclosure is not limited thereto. For example, the first direction can be a row direction, and the second direction can be a column direction.

[0075] When performing touch sensing, a touch drive signal is applied to a plurality of touch electrodes TE connected in a first direction or a second direction, and a touch detection signal is detected from at least one or more of the plurality of touch electrodes TE connected in the second direction or the first direction. When different signals are applied to the touch electrodes TE connected in the first direction and the touch electrodes TE connected in the second direction, a touch can be detected by detecting a change in the mutual capacitance between the touch electrodes TE caused by the touch.

[0076] The touch driving circuit 150 can output a touch driving signal to the touch electrode TE via the touch line TL, and can detect touch detection signals from at least one or more of the touch electrodes TE.

[0077] In one or more embodiments, the touch driving circuit 150 may include, for example, an operational amplifier connected to the touch line TL for providing touch driving signals and receiving touch detection signals, and a feedback capacitor for accumulating charge corresponding to the signals received by the operational amplifier. The touch driving circuit 150 may include an integrator, sample-and-hold circuitry, analog-to-digital converter, etc., for processing one or more output signals from the operational amplifier.

[0078] The touch driving circuit 150 can convert touch detection signals detected by one or more touch electrodes TE into digital touch detection data and provide the resulting touch detection data to the touch controller 160. The touch controller 160 can detect the presence or absence of a touch, touch coordinates, etc., based on the touch detection data received from the touch driving circuit 150.

[0079] Depending on the design requirements, the touch driving circuit 150 can be located in a circuit separate from the display panel 110, or it can be implemented in an integrated circuit together with the data driving circuit 130 or other circuits (or drivers).

[0080] According to the aforementioned configuration, even when touch sensing functionality can be provided using touch electrodes TE disposed on or in the display panel 110, touch sensing or display driving may be affected due to parasitic capacitance between the touch electrodes TE and the electrodes or signal lines used for display driving.

[0081] To address this issue, in one or more embodiments, the touch driving circuit 150 may include at least one dummy touch terminal connected to a dummy touch line that overlaps with a plurality of touch lines TL.

[0082] For example, a dummy touch line may be a loop extending in a second direction intersecting the first direction to overlap with multiple touch lines TL extending in the first direction, and connected to at least one dummy touch terminal.

[0083] Figure 2 An example subpixel SP configuration included in a touch display device 100 according to aspects of this disclosure is illustrated.

[0084] Reference Figure 2 Subpixel SP may include light-emitting element ED and driving transistor DRT configured to drive light-emitting element ED.

[0085] The light-emitting element ED may include a pixel electrode PE and a common electrode CE, and also includes a light-emitting layer EL located between the pixel electrode PE and the common electrode CE.

[0086] The pixel electrode PE of the light-emitting element ED can be an electrode set for each sub-pixel SP, and the common electrode CE can be an electrode set for all sub-pixels SP or one or more sub-pixels SP.

[0087] For example, the pixel electrode PE can be an anode electrode, and the common electrode CE can be a cathode electrode. In another example, the pixel electrode PE can be a cathode electrode, and the common electrode CE can be an anode electrode.

[0088] The pixel electrode PE of the light-emitting element ED can be connected to the fourth node N4, and the common electrode CE can be connected to the low-voltage line VSSL for transmitting the low voltage VSS.

[0089] For example, the light-emitting element ED can be at least one of organic light-emitting diode (OLED), light-emitting diode (LED), or quantum dot light-emitting element.

[0090] Subpixels (SPs) may also include one or more transistors in addition to the driving transistor (DRT). For example, see reference... Figure 2 Subpixel SP may include the first transistor to the fifth transistor (T1 to T5).

[0091] Reference Figure 2 The driving transistor DRT may include a first driving transistor DRT1 and a second driving transistor DRT2.

[0092] The driving transistor DRT may include a first node N1, a second node N2, and a third node N3. For example, the first node N1 may be the corresponding gate node of the first driving transistor DRT1 and the second driving transistor DRT2, the second node N2 may be the source or drain node of the first driving transistor DRT1, and the third node N3 may be the drain or source node of the second driving transistor DRT2.

[0093] The drain or source node of the first driving transistor DRT1 can be connected to the source or drain node of the second driving transistor DRT2, and the first driving transistor DRT1 can be connected to the high voltage line VDDL for passing the high voltage VDD through the second node N2.

[0094] The first transistor T1 can receive the first scan gating signal SCAN1 of the conduction voltage level from the gating drive circuit 120, and control the connection between the data line DL used to transmit the data voltage VDATA and the fifth node N5.

[0095] The first scan strobe signal SCAN1 of the conduction voltage level can be a high voltage level signal when the first transistor T1 is an n-type transistor, or a low voltage level signal when the first transistor T1 is a p-type transistor.

[0096] The second transistor T2 can receive a second scan gating signal SCAN2 with a conduction voltage level from the gating drive circuit 120 to control the connection between the first node N1 and the third node N3.

[0097] The fifth transistor T5 can receive a second scan gating signal SCAN2 with a conduction voltage level from the gating drive circuit 120 to control the connection between the fourth node N4 and the sixth node N6.

[0098] The fifth transistor T5 can be connected to the reference voltage line REFL, which is used to pass the reference voltage VREF, through the sixth node N6, and can provide the reference voltage VREF to the fourth node N4 during the turn-on operation.

[0099] When the second transistor T2 and the fifth transistor T5 are n-type transistors, the second scan strobe signal SCAN2, which is the conduction voltage level, can be a high-voltage signal, or when the second transistor T2 and the fifth transistor T5 are p-type transistors, it can be a low-voltage signal.

[0100] The third transistor T3 can receive the light emission control gating signal EM of the conduction voltage level from the gating drive circuit 120 and control the connection between the fifth node N5 and the sixth node N6.

[0101] The fourth transistor T4 can receive a light-emitting control gating signal EM of the conduction voltage level from the gating drive circuit 120 to control the connection between the third node N3 and the fourth node N4.

[0102] When the third transistor T3 and the fourth transistor T4 are n-type transistors, the light emission control gating signal EM at the conduction voltage level can be a high-voltage signal, or when the third transistor T3 and the fourth transistor T4 are p-type transistors, it can be a low-voltage signal.

[0103] The sub-pixel SP may also include a storage capacitor Cstg, which is disposed between the first node N1 and the fifth node N5 and maintains a constant voltage during a frame.

[0104] Reference Figure 2 The first driving transistor DRT1, the second driving transistor DRT2, and the first to fifth transistors (T1 to T5) can be p-type transistors. However, this disclosure is not limited thereto. For example, at least one of the first driving transistor DRT1, the second driving transistor DRT2, and the first to fifth transistors (T1 to T5) can be designed as an n-type transistor.

[0105] The first driving transistor DRT1, the second driving transistor DRT2, and the first to fifth transistors (T1 to T5) can be low-temperature polycrystalline silicon (LTPS) transistors. However, this disclosure is not limited thereto. For example, at least one of the first driving transistor DRT1, the second driving transistor DRT2, and the first to fifth transistors (T1 to T5) can be designed as an oxide transistor.

For example, a corresponding portion of the at least one dummy touch line may extend in a second direction (e.g., row direction) to overlap with multiple touch lines TL extending in a first direction (e.g., column direction).

[0108] In one or more embodiments, reference is made to Figure 3The touch driving circuit 150 may include a touch transmitting circuit 150-1 and a touch receiving circuit 150-2, and at least one dummy touch line may include a first dummy touch line DTL1 and a second dummy touch line DTL2, each connected to the touch transmitting circuit 150-1. The first dummy touch line DTL1 and the second dummy touch line DTL2 are initially not connected to any touch electrode TE.

[0109] For example, the touch transmitting circuit 150-1 can be connected to multiple touch transmitting lines (TTL1 to TTLn, where n is a positive integer) among multiple touch lines TL, and connected to a first dummy touch line DTL1 that overlaps with the multiple touch transmitting lines (TTL1 to TTLn) through at least one dummy touch transmitting terminal.

[0110] The touch receiving circuit 150-2 can be connected to multiple touch receiving lines (TRL1 to TRLm, where m is a positive integer) among multiple touch lines TL, and is connected to a second dummy touch line DTL2 that overlaps with the multiple touch receiving lines (TRL1 to TRLm) through at least one dummy touch receiving terminal.

[0111] Reference Figure 3 The first dummy touch line DTL1 may overlap with all of the multiple touch transmitting lines (TTL1 to TTLn), and the second dummy touch line DTL2 may overlap with all of the multiple touch receiving lines (TRL1 to TRLm). However, the embodiments of this disclosure are not limited thereto. For example, the first dummy touch line DTL1 may overlap with a portion of the multiple touch transmitting lines (TTL1 to TTLn), and the second dummy touch line DTL2 may overlap with a portion of the multiple touch receiving lines (TRL1 to TRLm).

[0112] In one or more embodiments, when the touch driving circuit 150 includes a first dummy touch terminal and a second dummy touch terminal, the first dummy touch terminal may be disposed on a first side (e.g., the left side) of the plurality of touch driving terminals, and the second dummy touch terminal may be disposed on a second side (e.g., the right side) of the plurality of touch driving terminals opposite to the first side. However, embodiments of this disclosure are not limited thereto.

[0113] For example, the touch transmitting circuit 150-1 may include a first touch transmitting terminal to an nth touch transmitting terminal respectively connected to a plurality of touch transmitting lines (TTL1 to TTLn). In this configuration, a first dummy touch transmitting terminal may be located adjacent to (e.g., immediately next to) the first touch transmitting terminal, and a second dummy touch transmitting terminal may be located adjacent to (e.g., immediately next to) the nth touch transmitting terminal.

[0114] For example, the touch receiving circuit 150-2 may include a first touch receiving terminal to a m-th touch receiving terminal respectively connected to multiple touch receiving lines (TRL1 to TRLm). In this configuration, a first dummy touch receiving terminal may be located adjacent to the first touch receiving terminal, and a second dummy touch receiving terminal may be located adjacent to the m-th touch receiving terminal.

[0115] For example, the two ends or two edges of a dummy touch line can be connected to the same dummy touch terminal.

[0116] In one or more embodiments, one end or one edge of the dummy touch line may be connected to a first dummy touch terminal, and the other end or another edge of the dummy touch line may be connected to a second dummy touch terminal.

[0117] For example, each of the first end DTL1-1 and the second end DTL1-2 of the first dummy touch line DTL1 can be connected to either the first dummy touch transmitting terminal or the second dummy touch transmitting terminal. For example, the first end DTL1-1 of the first dummy touch line DTL1 can be connected to the first dummy touch transmitting terminal, and the second end DTL1-2 of the first dummy touch line DTL1 can be connected to the second dummy touch transmitting terminal. Therefore, the first end of the first dummy touch line DTL1 is connected to the first dummy touch terminal, and the second end of the first dummy touch line DTL1 is connected to the second dummy touch terminal.

[0118] For example, either the first end DTL2-1 or the second end DTL2-2 of the second dummy touch line DTL2 can be connected to either the first dummy touch receiving terminal or the second dummy touch receiving terminal. For example, the first end DTL2-1 of the second dummy touch line DTL2 can be connected to the first dummy touch receiving terminal, and the second end DTL2-2 of the second dummy touch line DTL2 can be connected to the second dummy touch receiving terminal.

[0119] A dummy touch line can be electrically connected to any one of the multiple touch lines TL in the area where it overlaps with multiple touch lines TL.

[0120] In one or more embodiments, reference is made to Figure 3Because the third touch transmission line TTL3 is defective, the first dummy touch line DTL1 can be electrically connected to the third touch transmission line TTL3. In this implementation, the third touch transmission line TTL3 may be a line that needs to be repaired due to a line defect (such as being cut off, forming a short circuit, etc.) at at least one point within the portion of the third touch transmission line TTL3 from point P1 where the third touch transmission line TTL3 connects to the first dummy touch line DTL1 to the third touch transmission terminal of the touch transmission circuit 150-1. Therefore, the defective touch line includes a cut located between the position where the defective touch line connects to the dummy touch line and the position where the defective touch line connects to the touch driving terminal in the touch driving circuit.

[0121] When the first dummy touch line DTL1 is connected to the third touch transmission line TTL3, any point within a portion of the third touch transmission line TTL3 can be cut.

[0122] In this case, at least one of the multiple touch electrodes TE connected to the third touch transmission line TTL3 can receive a touch drive signal provided by the first terminal DTL1-1 or the second terminal DTL1-2 of the first dummy touch line DTL1 and transmitted through the first dummy touch line DTL1 connected to the third touch transmission line TTL3 at the connection point P1.

[0123] In one or more embodiments, a dummy touch line can be electrically connected to one and another of the multiple touch lines TL in an area where they overlap.

[0124] Reference Figure 3 The second dummy touch line DTL2 can be electrically connected to the defective third touch receiving line TRL3 and the defective (m-1)th touch receiving line TRLm-1. In this implementation, the third touch receiving line TRL3 may be a line that needs to be repaired due to a line defect at least at a point within the portion of the third touch receiving line TRL3 from point P2 where the third touch receiving line TRL3 connects to the second dummy touch line DTL2 to the third touch receiving terminal of the touch receiving circuit 150-2. Similarly, the (m-1)th touch receiving line TRLm-1 may also be a line that needs to be repaired due to a line defect at least at a point within the portion of the (m-1)th touch receiving line TRLm-1 from point P3 where the (m-1)th touch receiving line TRLm-1 connects to the second dummy touch line DTL2 to the (m-1)th touch receiving terminal of the touch receiving circuit 150-2.

[0125] When the second dummy touch line DTL2 is connected to the third touch receiving line TRL3 and the (m-1)th touch receiving line TRLm-1, any point within the portion of the third touch receiving line TRL3 and any point within the portion of the (m-1)th touch receiving line TRLm-1 can be cut.

[0126] Furthermore, the second dummy touch line DTL2 can be cut at any point within the portion of the second dummy touch line DTL2 from point P2, which connects to the third touch receiving line TRL3, to point P3, which connects to the (m-1)th touch receiving line TRLm-1. Therefore, the second dummy touch line DTL2 is cut at a position between point P2, where it connects to the third touch receiving line TRL3, and point P3, where it connects to the (m-1)th touch receiving line TRLm-1.

[0127] In this case, at least one of the multiple touch electrodes TE connected to the third touch receiving line TRL3 can send a touch detection signal to the touch receiving circuit 150-2 through the first terminal DTL2-1 of the second dummy touch line DTL2, and at least one of the multiple touch electrodes TE connected to the (m-1)th receiving line TRLm-1 can send a touch detection signal to the touch receiving circuit 150-2 through the second terminal DTL2-2 of the second dummy touch line DTL2.

[0128] Figure 4 and Figure 5 An example configuration of a touch driving circuit 150 according to an embodiment of this specification is illustrated, in which touch driving signals are provided via a dummy touch line DTL.

[0129] Reference Figure 4 and Figure 5 The touch sending circuit 150-1 of the touch driving circuit 150 can be connected to the first touch sending line to the nth touch sending line (TTL1 to TTLn) through the first touch sending terminal to the nth touch sending terminal (Tx(1) to Tx(n)) respectively, and can provide touch driving signals to the first touch sending line to the nth touch sending line (TTL1 to TTLn) in sequence.

[0130] For example, the touch sending circuit 150-1 can determine the touch scanning sequence in advance and control the transmission time of the touch driving signal to the first touch sending terminal to the nth touch sending terminal (Tx(1) to Tx(n)) based on the determined touch scanning sequence.

[0131] The touch receiving circuit 150-2 of the touch driving circuit 150 can be connected to the first touch receiving line to the m-th touch receiving line (TRL1 to TRLm) through the first touch receiving terminal to the m-th touch receiving terminal respectively, and can sequentially receive touch detection signals from the first touch receiving line to the m-th touch receiving line (TRL1 to TRLm).

[0132] For example, the touch receiving circuit 150-2 can determine the touch scanning sequence in advance and control the reception time of touch detection signals from the first touch receiving terminal to the m-th touch receiving terminal based on the determined touch scanning sequence.

[0133] Reference Figure 4 The third touch transmission line TTL3 among the first touch transmission lines to the nth touch transmission lines (TTL1 to TTLn) can be electrically connected to the first dummy touch line DTL1 connected to the first dummy touch transmission terminal Tx (d1) and can be repaired.

[0134] In this case, when the touch transmitting circuit 150-1 provides a touch driving signal through the third touch transmitting terminal Tx (3), it can provide the touch driving signal through the first dummy touch transmitting terminal Tx (d1) instead of the third touch transmitting terminal Tx (3), thereby providing the touch driving signal to at least one touch electrode connected to the third touch transmitting line TTL3. Therefore, the touch transmitting circuit 150-1 is configured to apply the touch driving signal to the first dummy touch line DTL1 through the dummy touch terminal at a time corresponding to the time when the touch driving signal should be provided to the defective touch line.

[0135] Reference Figure 5 Among the first touch receiving line to the nth touch receiving line (TRL1 to TRLn), the third touch receiving line TRL3 and the (n-1)th touch receiving line TRLn-1 can be electrically connected to the first dummy touch transmitting terminal Tx (d1) and the second dummy touch transmitting terminal Tx (d2) respectively, and can be repaired.

[0136] In this configuration, the touch receiving circuit 150-2 can receive the touch detection signal via the first dummy touch receiving terminal Tr (d1) instead of the third touch receiving terminal Tr (3) when the touch driving signal is provided via the third touch transmitting terminal Tx (3), and receive the touch detection signal via the second dummy touch receiving terminal Tr (d2) instead of the (n-1) touch receiving terminal Tr (n-1) when the touch driving signal is provided via the (n-1)th touch transmitting terminal Tx (n-1). Thus, the touch receiving circuit 150-2 can receive the touch detection signal via at least one touch electrode connected to the third touch transmitting line TTL3 and the (n-1)th touch transmitting line TTLn-1, respectively.

[0137] Figure 6 and Figure 7 An example structure for configuring touch electrodes TE in a touch display device 100 according to aspects of the present disclosure is illustrated.

[0138] Figure 6 and Figure 7 It can be Figure 3 An enlarged view of region 110-1 shown. Figure 6 A first example embodiment of a touch electrode TE according to embodiments of the present disclosure is illustrated, and Figure 7 A second exemplary embodiment of the touch electrode TE according to aspects of this disclosure is illustrated.

[0139] Reference Figure 6 In one or more example embodiments, the plurality of touch electrodes TE disposed in the display panel 110 may include a plurality of touch transmitting electrodes TE1 and a plurality of touch receiving electrodes TE2.

[0140] Multiple touch transmitting electrodes TE1 may extend in a second direction (e.g., row direction), and each of the touch transmitting electrodes TE1 may be connected to at least one adjacent touch transmitting electrode via at least one bridging pattern BD. The bridging pattern BD may also be described as a bridging metal.

[0141] Multiple touch receiving electrodes TE2 may extend in a first direction (e.g., column direction) and may have a strip shape.

[0142] Reference Figure 6 Each of the first touch receiving line to the m-th touch receiving line (TRL1 to TRLm) can be electrically connected to a corresponding one of the plurality of touch receiving electrodes TE2, and each of the plurality of touch receiving electrodes TE2 can overlap with at least one bridging pattern BD that connects the plurality of touch transmitting electrodes TE1.

[0143] Reference Figure 6 The touch transmitting electrodes TE1 arranged in the same row can be connected by at least one bridging pattern BD, and thus can receive touch driving signals transmitted through the same touch transmitting line.

[0144] For example, among a plurality of touch transmitting electrodes TE1, touch transmitting electrodes that receive touch driving signals via the nth touch transmitting line TTLn can be connected to each other via at least one bridging pattern BD.

[0145] In one or more embodiments, multiple touch transmitting electrodes TE1 and multiple touch receiving electrodes TE2 may be disposed in different layers, and multiple touch transmitting electrodes TE1 and multiple bridging patterns BD may be disposed in the same layer.

[0146] In one or more embodiments, a plurality of touch transmitting electrodes TE1 and a plurality of touch receiving electrodes TE2 may be disposed in the same layer, and a plurality of bridging patterns BD may be disposed in a different layer from the plurality of touch transmitting electrodes TE1 and the plurality of touch receiving electrodes TE2, and adjacent touch transmitting electrodes TE1 among the plurality of touch transmitting electrodes TE1 may be interconnected.

[0147] Reference Figure 6 The multiple touch transmitting electrodes TE1 can be designed to have a square shape, but the embodiments disclosed herein are not limited to this. For example, the multiple touch transmitting electrodes TE1 can be designed to have various shapes, including rhombuses.

[0148] Reference Figure 7 Multiple touch transmitting electrodes TE1 may extend in a second direction, and each of the multiple touch transmitting electrodes TE1 may be connected to at least one adjacent touch transmitting electrode through at least one first bridging pattern BD1.

[0149] Multiple touch receiving electrodes TE2 may extend in a first direction, and each of the multiple touch receiving electrodes TE2 may be connected to at least one adjacent touch receiving electrode via at least one second bridging pattern BD2. Each of the first bridging pattern BD1 and the second bridging pattern BD2 may be referred to as a bridging metal layer.

[0150] Reference Figure 7 The touch transmitting electrodes TE1 arranged in the same row can be connected through at least one of the multiple first bridging patterns BD1, thereby receiving touch drive signals from the same touch transmitting line. Furthermore, the touch receiving electrodes TE2 arranged in the same column can be connected through at least one of the multiple second bridging patterns BD2, thereby sending touch detection signals to the same touch receiving line.

[0151] For example, the touch transmitting electrode among the plurality of touch transmitting electrodes TE1 that receives the touch driving signal through the nth touch transmitting line TTLn can be connected to each other through at least one of the plurality of first bridging patterns BD1, and the touch receiving electrode among the plurality of touch receiving electrodes TE2 that sends the touch detection signal to the mth touch receiving line TRLm can be connected to each other through at least one of the plurality of second bridging patterns BD2.

[0152] In one or more embodiments, a plurality of touch transmitting electrodes TE1 and a plurality of touch receiving electrodes TE2 may be disposed in the same layer, and a plurality of first bridging patterns BD1 and a plurality of second bridging patterns BD2 may be disposed in different layers.

[0153] For example, multiple first bridging patterns BD1 can be disposed in the same layer as multiple touch transmitting electrodes TE1 and multiple touch receiving electrodes TE2, and multiple second bridging patterns BD2 can be disposed in different layers from multiple touch transmitting electrodes TE1 and multiple touch receiving electrodes TE2.

[0154] In another example, a plurality of first bridging patterns BD1 may be disposed in a different layer than the plurality of touch transmitting electrodes TE1 and the plurality of touch receiving electrodes TE2, and a plurality of second bridging patterns BD2 may be disposed in the same layer as the plurality of touch transmitting electrodes TE1 and the plurality of touch receiving electrodes TE2.

[0155] Reference Figure 7 The multiple touch transmitting electrodes TE1 and the multiple touch receiving electrodes TE2 may have a rhomboid shape, but this disclosure is not limited thereto. For example, the multiple touch transmitting electrodes TE1 may have various shapes, including square shapes.

[0156] Figure 8 An example configuration of a dummy touch line (DTL) included in a touch display device 100 according to various aspects of this disclosure is illustrated.

[0157] Reference Figure 8 A dummy touch line (DTL) can be set in a different layer than multiple touch lines (TL1 to TLk, where k is a positive integer).

[0158] For example, when the dummy touch line DTL is the first dummy touch line DTL1, the multiple touch lines (TL1 to TLk) can be touch transmitting lines (TTL1 to TTLn). Furthermore, when the dummy touch line DTL is the second dummy touch line DTL2, the multiple touch lines (TL1 to TLk) can also be touch receiving lines (TRL1 to TRLm).

[0159] Reference Figure 8 In one or more embodiments, the display panel 110 may include a touch sensor layer 800, wherein the touch sensor layer 800 may include at least one metal layer and two or more insulating layers for forming a plurality of touch electrodes TE and a plurality of touch lines TL.

[0160] The two or more insulating layers included in the touch sensor layer 800 may include a touch buffer layer 810, a first touch insulating layer 820, a second touch insulating layer 830, a touch planarization layer 840, etc.

[0161] For example, the touch buffer layer 810 can be an inorganic or organic insulating layer. Each of the first touch insulating layer 820 and the second touch insulating layer 830 can be an inorganic or organic insulating layer. The first touch insulating layer 820 and the second touch insulating layer 830 can also be referred to as a first interlayer insulating layer and a second interlayer insulating layer. The touch planarization layer 840 can be an organic or inorganic insulating layer and can also be referred to as a touch protective layer.

[0162] At least one metal layer included in the touch sensor layer 800 may include at least one of a first metal layer disposed between the touch buffer layer 810 and the first touch insulating layer 820, a second metal layer disposed between the first touch insulating layer 820 and the second touch insulating layer 830, and a third metal layer disposed between the second touch insulating layer 830 and the touch planarization layer 840.

[0163] Multiple touch electrodes TE can be disposed in at least one of the first to third metal layers. Multiple touch lines TL can be disposed in at least one of the first to third metal layers.

[0164] For example, each of the plurality of touch electrodes TE may include sensor metal serving as a touch sensor and bridging metal connecting the sensor metal. The sensor metal may be disposed within a sensor metal layer, and the bridging metal may be disposed within a bridging metal layer. The sensor metal layer may be one of a first to a third metal layer (e.g., a second or third metal layer), and the bridging metal layer may be another of the first to third metal layers (e.g., a first or second metal layer).

[0165] A dummy touch line (DTL) can be set on multiple touch lines (TL1 to TLk). For example, a dummy touch line (DTL) can be set in a different metal layer than the multiple touch lines (TL). For example, a dummy touch line (DTL) can be set in the same metal layer as the multiple touch electrodes (TE). In another example, a dummy touch line (DTL) can be set in a different metal layer than the multiple touch electrodes (TE).

[0166] In one or more aspects, the dummy touch line DTL can be located in a metal layer at a higher position than the multiple touch lines (TL1 to TLk).

[0167] In one or more embodiments, the dummy touch line (DTL) can be set in the non-display area NA instead of the display area AA.

[0168] For example, such as Figure 8As shown, the second touch insulation layer 830 can be disposed between the dummy touch line DTL and multiple touch lines (TL1 to TLk). At least a portion of the dummy touch line DTL can overlap with at least a portion of the multiple touch lines (TL1 to TLk) or at least one or more of the multiple touch lines (TL1 to TLk).

[0169] In one or more aspects, a dummy touch line (DTL) can be electrically connected to the (k-1)th touch line (TLk-1) among multiple touch lines (TL1 to TLK). For example, during a repair process in panel manufacturing, the dummy touch line (DTL) can be electrically connected to the (k-1)th touch line (TLk-1) via a laser melting-based welding process.

[0170] Figure 9 An example stacked structure of a display panel 110 according to aspects of this disclosure is illustrated.

[0171] Reference Figure 8 and Figure 9 In one or more exemplary embodiments, the display panel 110 may include a substrate SUB, on which a display area AA and a non-display area NA are defined, a plurality of insulating layers disposed on the substrate SUB, and a light-emitting element layer 950 disposed on the plurality of insulating layers.

[0172] For example, the multiple insulating layers may include a buffer layer 901, a first insulating layer 902, a second insulating layer 903, a third insulating layer 904, and a planarization layer 905.

[0173] At least one transistor 910 and a light-emitting element layer 950, including the sub-pixel SP, can be disposed in the display area AA of the substrate SUB, and a touch sensor layer 800 can be disposed on the light-emitting element layer 950. An encapsulation layer 960 can be disposed between the light-emitting element layer 950 and the touch sensor layer 800.

[0174] Multiple signal lines SL used to apply signals for display driving or to provide voltage can be set in the non-display area NA of the substrate SUB.

[0175] For example, the signal line SL can be a line included in the gating drive circuit 120, and the signal line SL can transmit signals provided from the pad components to the scan driver or light emission control driver in the gating drive circuit 120. For example, the signal line SL can be a clock line.

[0176] The touch sensor layer 800 may include multiple touch electrodes TE, multiple touch lines TL connected to the multiple touch electrodes TE, and dummy touch lines DTL overlapping with the multiple touch lines TL in the non-display area NA.

[0177] In one or more aspects, at least one blocking pattern may be provided between the signal line SL and the touch line.

[0178] The signal line SL can be configured not to overlap with the touch line TL to prevent or reduce noise that may occur when detecting touch detection signals through the touch line TL. The signal line SL may include at least one first signal line SL1 and at least one second signal line SL2 arranged in different layers.

[0179] The blocking pattern may be configured to surround the display area AA, and in one or more aspects, at least a portion of the blocking pattern may extend beyond the boundary of the display area AA and be disposed inside the display area AA. In one or more aspects, the blocking pattern may be disposed outside the display area AA and spaced apart from the boundary of the display area AA.

[0180] The blocking pattern may include a first blocking pattern BP1 and a second blocking pattern BP2.

[0181] The blocking pattern can be a blocking layer including a first blocking pattern BP1 and multiple blocking pattern holes BH. Multiple blocking pattern holes BH can be provided to prevent or reduce the degradation of the light-emitting element layer 950 due to outgassing in the planarization layer 905.

[0182] The second blocking pattern BP2 can be a portion of the first blocking pattern BP1 extending in the vertical direction. Since the second blocking pattern BP2 is disposed between at least one signal line SL and at least one touch line, the impact of noise caused by the signal line SL on the touch line can be reduced.

[0183] In one or more aspects, the dummy touch pattern TD may also be disposed in a portion of the non-display area NA of the substrate SUB. The dummy touch pattern TD may be disposed between the touch line TL and the outer edge (or end) of the substrate SUB.

[0184] In one or more aspects, the dummy touch pattern TD can be insulated from multiple touch lines TL and multiple touch electrodes TE. For example, a constant voltage can be applied to the dummy touch pattern TD. The dummy touch pattern TD can disperse noise caused by parasitic capacitance formed by the signal lines SL of the gating driver, thereby reducing noise caused by the signal lines SL.

[0185] In the following text, refer to Figure 9 The cross-sectional structure of the display panel 110 will be discussed in more detail, but the features of the display panel 110 according to aspects of this disclosure are not limited to those described herein. Figure 9 of examples.

[0187] For example, the substrate SUB may include at least one of polyimide (PI), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyethersulfone, and polycarbonate, but aspects of this disclosure are not limited thereto.

[0188] When the substrate SUB comprises polyimide, the substrate SUB can be in the form of two polyimides. For example, an inorganic film can also be disposed between two polyimides.

[0189] Buffer layer 901 may be disposed on substrate SUB. Buffer layer 901 may comprise an insulating inorganic material such as silicon nitride (SiNx) or silicon oxide (SiOx), or may comprise an insulating organic material. However, the aspects of this disclosure are not limited thereto.

[0190] The buffer layer 901 can be a single layer or multiple layers of silicon nitride (SiNx) or silicon oxide (SiOx). In an example where the buffer layer 901 includes multiple layers, silicon oxide (SiOx) and silicon nitride (SiNx) can be formed alternately.

[0191] Depending on the type and material of the substrate SUB, the structure and type of the transistor, etc., the buffer layer 901 can be omitted.

[0192] At least one transistor 910 may be disposed on the buffer layer 901. At least one transistor 910 may include a semiconductor pattern 911, a gate electrode 912, a first electrode 913, and a second electrode 914. For example, the first electrode 913 may be a source electrode or a drain electrode, and the second electrode 914 may be a drain electrode or a source electrode.

For example, semiconductor pattern 911 may include one of indium gallium zinc oxide (IGZO), indium zinc oxide (IZO), indium gallium tin oxide (GTO), and indium gallium oxide (IGO), but aspects of this disclosure are not limited thereto. In the example where semiconductor pattern 911 includes an oxide semiconductor, the effect of blocking leakage current can be excellent, and thereby minimize or reduce the brightness change of sub-pixels during low-speed driving.

The third insulating layer 904 can be disposed between the gate electrode 912 and the first electrode and the second electrode (913 and 914), thereby insulating the gate electrode 912 from the first electrode and the second electrode (913 and 914) from each other.

[0213] In one or more embodiments, a first signal line SL1 of the signal lines SL may be disposed on a third insulating layer 904 in the non-display area NA. The first signal line SL1 may be a single signal line or may include at least two or more signal lines. When the first signal line SL1 includes at least two or more signal lines, these signal lines may be spaced apart from each other.

[0214] In one or more embodiments, a high-voltage line VDDL and a low-voltage line VSSL may be disposed on a third insulating layer 904. The high-voltage line VDDL can carry a high voltage. The low-voltage line VSSL can carry a low voltage.

[0215] The planarization layer 905 can be disposed on the first electrode 913, the second electrode 914 and the first signal line SL1.

[0216] The planarization layer 905 can protect at least one transistor 910 disposed beneath the planarization layer 905, and can reduce steps or flatten step differences by various patterns.

[0217] Considering the configuration of the electrodes, the planarization layer 905 can be a single layer or include two or more layers.

[0218] As high-resolution display devices become increasingly common, the number of signal lines disposed in display device 100 can be increased, and considering the difficulty of distributing all lines in a single layer while maintaining minimal spacing between them, the signal lines can be designed to be disposed in two or more layers. Such additional layers can provide space for line arrangement, thus display device 100 can offer the advantage of easier or more efficient arrangement of lines and electrodes. In an example where a multi-layered planarization layer 905 comprises a dielectric material, the planarization layer 905 can be used to form capacitors between metal layers.

[0219] When the planarization layer 905 includes two layers, the planarization layer 905 may include a first planarization layer 905-1 and a second planarization layer 905-2.

[0220] In one or more aspects, a second signal line SL2 among signal lines SL can be disposed between the first planarization layer 905-1 and the second planarization layer 905-2 in the non-display area NA.

[0225] The dam 940 can define multiple sub-pixels SP to minimize or reduce light leakage and prevent or reduce color mixing that may occur under various viewing angles.

[0226] The dam 940 can define (or distinguish) a light-emitting region EA that can emit light and a non-light-emitting region NEA that cannot emit light, and the dam 940 can be disposed in the non-light-emitting region NEA.

[0227] The dam 940 can be transparent, or configured to be black or one or more other colors. The dam 940 can be configured to cover one or more ends of the pixel electrode 951.

[0228] At least one spacer 954 may be disposed on the embankment 940. The spacer 954 can prevent or reduce damage to the light-emitting element layer 950, and minimize or reduce damage to the display device 100 from external impacts. The spacer 954 may comprise the same material as the embankment 940. The spacer 954 may be formed simultaneously with the embankment 940 or in a separate process. The height of the spacer 954 may be greater than the height of the embankment 940.

[0230] The light-emitting element layer 950 may further include a hole injection layer, a hole transport layer, an electron transport layer, and an electron transport layer, which are disposed above or below the light-emitting layer 952. However, the present disclosure is not limited thereto.

[0232] Multiple light-emitting layers 952 can be set for each sub-pixel SP. In this implementation, the charge generation layer can be set between two or more light-emitting layers 952.

[0233] A common electrode 953 can be disposed on the light-emitting layer 952. The common electrode 953 can be configured to extend from the display area AA to the non-display area NA.

[0234] The common electrode 953 can provide electrons to the light-emitting element layer 950 and can include a conductive material with a low work function.

[0235] Reference Figure 9 The area where the pixel electrode 951, the light-emitting layer 952, and the common electrode 953 overlap can be the light-emitting area EA.

[0236] An encapsulation layer 960 may be disposed on the common electrode 953. The encapsulation layer 960 can protect the light-emitting element layer 950 from external moisture, oxygen, or unwanted substances. For example, the encapsulation layer 960 can prevent or reduce the penetration of oxygen and moisture from the outside into the materials of the light-emitting layer 952, as well as the materials of the pixel electrode 951 and the common electrode 953, and prevent or reduce the oxidation of these materials.

[0240] Each of the first encapsulation layer 961 and the third encapsulation layer 963 may be in the form of at least two or more layers. For example, the first encapsulation layer 961 may include a three-layer structure of silicon oxide (SiOx), silicon nitride (SiNx), and silicon oxide (SiOx), but this disclosure is not limited thereto. For example, the first encapsulation layer 961 may include a four-layer structure of silicon oxide (SiOx), silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxide (SiOx), but this disclosure is not limited thereto.

[0241] The second encapsulation layer 962 may cover unwanted substances or particles that may appear during the manufacturing process. In one or more aspects, the second encapsulation layer 962 may planarize the surface of the first encapsulation layer 961. For example, the second encapsulation layer 962 may be a particle covering layer, but this disclosure is not limited thereto.

[0242] The second encapsulation layer 962 may be an organic material (e.g., a polymer such as silicon oxide carbon (SiOCz) epoxy resin, polyimide, polyethylene, or acrylate), but this disclosure is not limited thereto.

[0243] The second encapsulation layer 962 may include a thermosetting material or a photocurable material that can be cured by heating or light.

The touch buffer layer 810 may prevent chemical solutions (developers, etchants, etc.) used in the manufacturing process of the touch sensor layer 800 or moisture from the outside from penetrating into the light-emitting element layer 950, which includes organic materials.

[0246] In addition, the touch buffer layer 810 can prevent or reduce the short circuit of multiple touch sensor metals disposed on the touch buffer layer 810 due to external impact, and block interference signals that may occur when the touch sensor layer is driven.

[0247] A first touch insulating layer 820 may be disposed on a touch buffer layer 810, and a second touch insulating layer 830 may be disposed on a first touch insulating layer 820. In one or more aspects, at least one of a plurality of touch lines TL disposed on the first touch insulating layer 820 may be electrically connected to a dummy touch line DTL disposed on the second touch insulating layer 830.

[0248] The touch planarization layer 840 can be disposed on the second touch insulating layer 830.
