Description

[0001] This application claims priority and benefit to Korean Patent Application No. 10-2020-0044861, filed on April 13, 2020, which is incorporated herein by reference for all purposes, as fully set forth herein. Technical Field

[0003] Electronic devices such as smartphones, tablets, laptops, and smart TVs are being developed. These devices include display devices for providing information.

[0004] Recently, in addition to displaying images via a display panel, display devices can include input sensors capable of interacting with the user. When a user touches or approaches the screen with their finger, a sensor pen, or similar object, the input sensor determines whether the object is touching the screen and its touch coordinates. The display device can then receive image signals based on these touch coordinates.

[0005] The information disclosed in this background section is only for understanding the background of the inventive concept, and therefore may contain information that does not constitute prior art. Summary of the Invention

[0006] The applicant recognizes that the electric field between the input device (e.g., a pen) and the sensing wiring in the input sensor can distort the signal transmitted through the sensing wiring.

[0007] A display device constructed according to the principles and exemplary embodiments of the invention can improve the sensing reliability of an input sensor on a display panel by providing a blocking member on the sensing wiring to prevent the generation of an electric field between the input device and the sensing wiring. Furthermore, the blocking member can also prevent signal transmission through the sensing wiring from being distorted by the input device.

[0046] In the following description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of various embodiments or implementations of the invention. As used herein, “embodiment” and “implementation” are interchangeable terms and are non-limiting examples of apparatus or methods employing one or more of the inventive concepts disclosed herein. However, it will be apparent that various embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and apparatuses are shown in block diagram form to avoid unnecessarily obscuring the various embodiments. Furthermore, the various embodiments may be different, but are not necessarily exclusive. For example, a particular shape, configuration, and characteristic of one embodiment may be used or implemented in another embodiment without departing from the inventive concept.

[0047] Unless otherwise stated, the embodiments shown are to be understood as exemplary features providing details of variations in some manner in which the inventive concept can be implemented in practice. Therefore, unless otherwise stated, features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter individually or collectively referred to as “elements”) of various embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0048] Crosshairs and / or shading are typically used in accompanying drawings to clearly define the boundaries between adjacent elements. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, scale, commonalities between the elements shown, or any other characteristics, properties, etc., of the elements. Furthermore, in the drawings, the dimensions and relative dimensions of elements may be exaggerated for clarity and / or descriptive purposes. When embodiments can be implemented differently, the specific process sequence may be performed differently than the described sequence. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Moreover, the same reference numerals denote the same elements.

[0049] When a component (such as a layer) is referred to as being "on," "connected to," or "bonded to" another component or layer, the component may be directly on, directly connected to, or bonded to the other component or layer, or there may be intermediate components or intermediate layers. However, when a component or layer is referred to as being "directly on," "directly connected to," or "directly bonded to" another component or layer, there are no intermediate components or intermediate layers. Therefore, the term "connection" can refer to a physical, electrical (electrical), and / or fluid connection with or without intermediate components. Furthermore, the D1, D2, and D3 axes are not limited to the three axes of a Cartesian coordinate system, such as the x-axis, y-axis, and z-axis, and can be interpreted in a broader sense. For example, the D1, D2, and D3 axes can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be understood as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0050] Although the terms “first,” “second,” etc., may be used here to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Therefore, without departing from the publicly stated teachings, the first element discussed below may be referred to as the second element.

[0051] For descriptive purposes, spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” “side” (e.g., as in “sidewall”), etc., may be used herein to describe the relationship of one element to another (other) element as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, spatial relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture. For example, if the device in the drawings is flipped, an element described as “below” or “under” other elements or features would subsequently be positioned “above” other elements or features. Thus, the exemplary term “below” can encompass both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), and thus, the spatial relative descriptive terms used herein shall be interpreted accordingly.

[0052] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are also intended to include the plural forms. Furthermore, when the terms “comprising,” “including,” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, elements, components, and / or groups thereof, but does not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than terms of degree, and thus to explain the inherent biases in measurements, calculated values, and / or provided values ​​that will be recognized by those skilled in the art.

[0053] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure is a part. Terms such as those defined in common dictionaries shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0055] Reference Figure 1 and Figure 2The display device EA can be a device activated by an electrical signal. The display device EA can be applied to or take various forms of embodiments. For example, the display device EA can be used not only for large-size display devices such as televisions, monitors, or outdoor billboards, but also for small-to-medium-sized display devices such as personal computers, laptops, personal digital terminals, car navigation units, game consoles, portable electronic devices, smartphones, and cameras. Furthermore, these examples are presented only as embodiments and can therefore be used for other display devices without departing from the inventive concept. In the illustrated embodiment, the display device EA is exemplarily shown as a tablet computer.

[0056] The display device EA can display an image IM on a display surface FS that is parallel to the first direction DR1 and the second direction DR2, respectively, facing a third direction DR3. The image IM can include still images and moving images. Figure 1 A watch window and icon are shown as an example of an image IM. The display surface FS on which the image IM is displayed can correspond to the front surface of the display device EA, and can correspond to the front surface of the window WP.

[0057] In the illustrated embodiment, a front (or upper) surface and a rear (or lower) surface of each component are defined relative to the direction along which the displayed image IM is oriented. The front and rear surfaces may be opposite each other on a third direction DR3, and the normal direction of each of the front and rear surfaces may be parallel to the third direction DR3. In the specification, the surface defined by the first direction DR1 and the second direction DR2 is defined as a plane, and "viewing on a plane" may be defined as viewing from the third direction DR3.

[0058] The third direction DR3 can be a direction that intersects with the first direction DR1 and the second direction DR2. The first direction DR1, the second direction DR2, and the third direction DR3 can be orthogonal to each other.

[0059] The display device EA may include a window WP, a display module DM, and a housing HU. In the illustrated embodiment, the window WP and the housing HU may be combined to form the exterior of the display device EA.

The display surface FS can include a transmissive region TA and a bezel region BZA. The transmissive region TA can be an optically transparent region. For example, the transmissive region TA can be a region with a visible light transmittance of about 90% or more.

[0062] The border area BZA can have a predetermined color. The border area BZA can cover the outer area of ​​the display module DM to prevent the outer area from being seen from the outside. However, this is only shown as an example; in a window WP, the border area BZA can be omitted.

[0063] The display module DM can display an image IM and sense external input. The display module DM may include a display panel DP and an input sensor IS.

[0064] The display panel (DP) can be a light-emitting display panel and is not specifically limited to any particular type.

The emitting layer of an organic light-emitting display panel can include organic light-emitting materials. The emitting layer of a quantum dot light-emitting display panel can include quantum dots, quantum rods, etc.

[0065] An input sensor IS can be mounted on the display panel DP. The input sensor IS can have a multi-layered structure. The input sensor IS can sense external input applied from the outside. External input can be user input. User input can include various forms of external input, such as a part of the user's body, light, heat, a pen, or pressure.

[0066] The housing HU can be combined with the window WP. The housing HU can be combined with the window WP to provide a predetermined internal space. The display module DM can be accommodated in the internal space.

[0067] The housing HU may include materials with relatively high rigidity. For example, the housing HU may include multiple frames and / or panels formed of glass, plastic, or metal, or combinations thereof. The housing HU can stably protect the components of the display device EA housed within the internal space from external impacts.

[0068] According to an embodiment, the display device EA can sense touch coordinates based on the movement of a sensing pen PN. The sensing pen PN may include a body component BD and a sensing component DT connected to one end of the body component BD. The body component BD may include a power unit that can supply power to the sensing component DT. The sensing component DT may correspond to a common pen tip. The sensing component DT may include a conductive material. The sensing component DT can generate an electric field between surrounding conductive objects in response to the power supplied from the power unit. The sensing pen PN may include an active electrostatic pen (AES pen).

The display circuit layer DP-CL may include a semiconductor layer, multiple insulating layers, and multiple conductive layers. The multiple conductive layers of the display circuit layer DP-CL can form signal lines or control circuits for pixels.

[0074] The image implementation layer DP-OLED can be disposed on the display circuit layer DP-CL. The image implementation layer DP-OLED may include organic light-emitting diodes. However, this is just an example; the image implementation layer DP-OLED may also include inorganic light-emitting diodes, organic-inorganic light-emitting diodes, or a liquid crystal layer.

[0075] The input sensor IS can be mounted on the display panel DP. The input sensor IS may include a second substrate layer BS2 and a sensing circuit layer ML-T.

[0076] The second substrate layer BS2 can be disposed on the image implementation layer DP-OLED. A predetermined space can be defined between the second substrate layer BS2 and the image implementation layer DP-OLED. The space can be filled with air or an inert gas. Alternatively, the space can be filled with a filler, such as a silicone polymer, epoxy resin, or acrylic resin.

[0077] The sensing circuit layer ML-T can be disposed on the second substrate layer BS2. The sensing circuit layer ML-T may include multiple insulating layers and multiple conductive layers. The multiple conductive layers may include multiple sensing electrodes for sensing external inputs and multiple lines in the form of sensing wiring electrically connected to the multiple sensing electrodes respectively. This will be described later.

[0078] The bonding component SLM can be disposed between the first substrate layer BS1 and the second substrate layer BS2. The bonding component SLM can combine the first substrate layer BS1 and the second substrate layer BS2. The bonding component SLM can include organic materials such as photocurable resins or photoplastic resins, or inorganic materials such as glass sealants, and is not limited to any particular configuration.

[0079] Figure 3B yes Figure 2 A cross-sectional view of another embodiment of the display module is shown in the description. Figure 3B At the same time, the same reference numerals are applied to... Figure 3A The same components described in the previous section will be used, and repeated descriptions will be omitted to avoid redundancy.

[0080] Reference Figure 3B The display module DM-1 may include a display panel DP-1 and an input sensor IS-1. The input sensor IS-1 may be referred to as the input sensor layer.

[0081] The display panel DP-1 may include a first substrate layer BS1, a display circuit layer DP-CL, an image realization layer DP-OLED, and a thin film encapsulation layer TFE.

[0082] A thin-film encapsulation layer (TFE) can be disposed on the image realization layer (DP-OLED) to cover the DP-OLED. The TFE may include a first inorganic layer, an organic layer, and a second inorganic layer stacked sequentially along the third direction DR3. However, this is an example, and the TFE is not limited thereto. For example, the TFE may also include multiple inorganic layers and multiple organic layers.

[0083] The first inorganic layer can prevent external moisture or oxygen from penetrating the image realization layer of the DP-OLED. For example, the first inorganic layer may include silicon nitride, silicon oxide, or a combination thereof.

[0084] An organic layer may be disposed on the first inorganic layer to provide a flat surface. The organic layer may cover curvature formed on the upper surface of the first inorganic layer or particles present on the first inorganic layer. For example, the organic layer may include an acrylic organic layer, but is not limited thereto.

[0085] The second inorganic layer can be disposed on top of the organic layer to cover it. The second inorganic layer can seal off moisture and other substances emanating from the organic layer to prevent them from leaking to the outside. The second inorganic layer may include silicon nitride, silicon oxide, or a combination thereof.

[0086] The input sensor IS-1 can be formed on the display panel DP-1 through a continuous process. In this case, the input sensor IS-1 can be indicated as being directly mounted on the display panel DP-1. Direct mounting indicates that no third component is provided between the input sensor IS-1 and the display panel DP-1. That is, no separate adhesive component is required between the input sensor IS-1 and the display panel DP-1.

[0087] The input sensor IS-1 may include a substrate insulating layer IS-IL0 and a sensing circuit layer ML-T.

[0088] The substrate insulating layer IS-IL0 can be disposed on the thin-film encapsulation layer TFE. The substrate insulating layer IS-IL0 can include inorganic materials, organic materials, or composite materials. The substrate insulating layer IS-IL0 can be directly disposed on the display panel DP-1. For example, the substrate insulating layer IS-IL0 can be in direct contact with the thin-film encapsulation layer TFE. The substrate insulating layer IS-IL0 can have a single-layer or multi-layer structure. Optionally, the substrate insulating layer IS-IL0 can be omitted.

[0089] The sensing circuit layer ML-T can be disposed on the substrate insulating layer IS-IL0.

[0090] Figure 4 yes Figure 2 A plan view of an embodiment of the display panel shown in the figure.

[0091] Reference Figure 4 The display panel DP may include a first substrate layer BS1, multiple pixels PX, multiple signal lines GL, DL, PL and ECL, and multiple display pads (or "soldering pads") PDD.

[0092] The effective area AA and the adjacent peripheral area NAA can be defined within the display panel DP. The effective area AA can be the displayed image IM (see...). Figure 1 The effective area AA can be a region containing driving circuitry or driving lines. Multiple pixels PX can be set within the effective area AA. The effective area AA can be combined with the transmission area TA (see...). Figure 1 The outer region NAA can correspond to the border region BZA (see...). Figure 1 )correspond.

[0093] Multiple signal lines GL, DL, PL, and ECL can be disposed on the first substrate layer BS1. These signal lines GL, DL, PL, and ECL can be connected to multiple pixels PX to transmit electrical signals to the multiple pixels PX. Exemplary examples of the signal lines included in the display panel DP include multiple scan lines GL (hereinafter referred to as scan lines), multiple data lines DL (hereinafter referred to as data lines), multiple power lines PL (hereinafter referred to as power lines), and multiple emission control lines ECL (hereinafter referred to as emission control lines). However, this is an example; the multiple signal lines GL, DL, PL, and ECL may also include initialization voltage lines and are not limited to any particular configuration. The multiple signal lines GL, DL, PL, and ECL can constitute the display circuit layer DP-CL (see [link to display circuit layer]). Figure 3A ).

[0094] The power pattern VDD can be set in the peripheral area NAA. The power pattern VDD can be connected to the power line PL. The display panel DP can include the power pattern VDD to provide the same power signal to multiple pixels PX.

[0095] The display pad (PDD) may include a first pad (D1) and a second pad (D2). Multiple first pads (D1) may be configured. Multiple first pads (D1) may be connected to data lines (DL) respectively. The second pad (D2) may be connected to the power pattern (VDD) to electrically connect to the power line (PL). The display panel (DP) can provide externally supplied electrical signals to multiple pixels (PX) via the display pad (PDD). In addition to the first pads (D1) and the second pads (D2), the display pad (PDD) may also include pads for receiving other electrical signals, and is not limited to any particular configuration.

[0096] The driver chip IC can be installed in the peripheral area NAA. The driver chip IC can be a chip-type timing control circuit. Data lines DL can be electrically connected to multiple first pads D1 via the driver chip IC. However, as an example, the driver chip IC can be installed on a film separate from the display panel DP. In this case, the driver chip IC can be electrically connected to the display pad PDD via the film.

[0097] Figure 5 yes Figure 2 The diagram shows a plan view of a first embodiment of the input sensor.

[0098] Reference Figure 1 , Figure 4 and Figure 5 The input sensor IS may include a second substrate layer BS2, multiple sensing electrodes TE1 and TE2, multiple lines in the form of sensing wiring TL1, TL2 and TL3, multiple sensing pads PDT, and a blocking component BK. The blocking component BK may be in the form of a shielding layer or any other structure or component that blocks electrical or electrostatic interference from reaching the sensing wiring.

[0099] The effective area AA-I and the adjacent peripheral area NAA-I can be defined within the input sensor IS. The effective area AA-I can be the area sensing external input, and the peripheral area NAA-I can be the area with wiring, etc. Multiple sensing electrodes TE1 and TE2 can be disposed within the effective area AA-I. The effective area AA-I can correspond to the effective area AA of the transmission area TA and the display panel DP. The peripheral area NAA-I can correspond to the bezel area BZA and the peripheral area NAA of the display panel DP.

[0100] The display device EA may also include a controller CT that controls the input sensor IS. The controller CT can control the input sensor IS to operate in a first mode or a second mode.

[0101] The first mode could be a touch mode that recognizes input via a part of the user's body.

[0102] In the first mode, multiple first sensing electrodes TE1 can output sensing signals, and multiple second sensing electrodes TE2 can receive driving signals. In this case, the display device EA can apply driving signals to the multiple second sensing electrodes TE2 to scan the effective area AA-I, and can sense the area of ​​the applied touch by the sensing signals output from the multiple first sensing electrodes TE1. For example, the input sensor IS can be driven in the first mode in a capacitive (e.g., mutual capacitance) type.

[0103] This configuration is illustrated by way of example, in which multiple first sensing electrodes TE1 can receive drive signals and multiple second sensing electrodes TE2 can output sensing signals, and additionally receive or output other electrical signals.

[0104] The second mode can be a mode following the first mode. The second mode can be a pen mode that identifies the sensing pen PN.

[0105] In the second mode, the same sensing signal can be provided to multiple first sensing electrodes TE1 and multiple second sensing electrodes TE2. The sensing signal can be a substantially constant voltage. The substantially constant voltage can have a different voltage than the voltage provided to the sensing element DT. For example, the substantially constant voltage can have a value of about 1V to about 2V. However, this is an example, and the value of the substantially constant voltage is not limited to this. For example, the substantially constant voltage can have a ground voltage.

[0106] Additionally, the input sensor IS can sense changes in the amount of voltage / current supplied to the multiple first sensing electrodes TE1 and multiple second sensing electrodes TE2. The input sensor IS can identify touch coordinates based on these changes in voltage / current. For example, the input sensor IS can be driven by sensing electrostatic signals input from an external source (e.g., an active electrostatic pen (AES pen)) in a second mode.

[0107] The multiple sensing electrodes TE1 and TE2 may include multiple first sensing electrodes TE1 and multiple second sensing electrodes TE2. The multiple first sensing electrodes TE1 and multiple second sensing electrodes TE2 may be disposed in the effective region AA-I.

[0108] According to an embodiment, when the sensing pen PN touches or approaches the input sensor IS in the second mode, the input sensor IS can sense the touch coordinates. When the sensing element DT of the sensing pen PN touches or approaches the input sensor IS, an electric field can be generated between the sensing element DT and the plurality of sensing electrodes TE1 and TE2.

[0109] In this scenario, the voltage intensity supplied to the sensing component DT and the voltage intensity supplied to the multiple sensing electrodes TE1 and TE2 can differ from each other. When the voltage intensity supplied to the sensing component DT differs from the voltage intensity supplied to the multiple sensing electrodes TE1 and TE2, a potential difference can be generated. Due to this potential difference, an electric field can be generated between the sensing component DT and the multiple sensing electrodes TE1 and TE2.

However, according to an embodiment, the blocking component BK-2 may block the sensor pen PN from passing through the boundary between the effective area AA-I and the peripheral area NAA-I (see...).

These modes can operate sequentially based on time t. They can also operate for the same time period. However, this is just an example; the operating times of MD1, MD2, and MD3 are not limited to this. For instance, their operating times can differ from each other.

A sensing signal identical to the sensing signals of the multiple first sensing electrodes TE1 and the multiple second sensing electrodes TE2 can be provided to the multiple sensing wires TL1, TL2, and TL3. A compensation voltage V1 can be provided to the blocking component BK. The sensing signal and the compensation voltage V1 can have substantially the same value. Therefore, no parasitic capacitance can be generated between the blocking component BK and the multiple sensing wires TL1, TL2, and TL3. When sensing the sensing pen PN (see...) in the effective area AA-I... Figure 1 When this is done, signal distortion caused by parasitic capacitance can be prevented.
