[0035] In this specification, it will also be understood that when a component (or region, layer, portion) is referred to as being "on" another component, "connected to" or "attached to" another component, the component may be located directly on, directly connected to or directly attached to the other component, or there may be an intermediate third component.

[0036] The same reference numerals always denote the same elements. Furthermore, in the figures, the thickness, scale, and dimensions of the components are exaggerated for clarity.

[0037] The term “and / or” includes any and all combinations of one or more of the relevant listed items.

[0038] It will be understood that while terms such as “first” and “second” are used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one component from another. For example, a first element referred to as a first element in one embodiment may be referred to as a second element in another embodiment without departing from the scope of the appended claims. Unless otherwise stated, singular terms may include plural forms.

[0039] Furthermore, terms such as "below," "under," "above," and "above" are used to explain the relationships between the components shown in the accompanying drawings. These terms can be relative concepts and are described based on the directions indicated in the drawings.

[0040] 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. Terms (such as those defined in a general dictionary) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field, and terms shall not be interpreted in an idealized or over-interpreted manner as having a formalized meaning, unless expressly defined in the description.

[0041] The meaning of "includes" or "contains" refers to a property, a fixed quantity, a step, an operation, a component, a part, or a combination thereof, but does not exclude other properties, fixed quantities, steps, operations, components, parts, or combinations thereof.

[0042] In the following description, some exemplary embodiments of the inventive concept will be described in more detail with reference to the accompanying drawings.

[0043] Figure 1A These are combined perspective views of electronic devices based on some exemplary embodiments of the inventive concept. Figure 1B This is an exploded perspective view of an electronic device based on some example embodiments of the inventive concept. Figure 1C It is along Figure 1B A cross-sectional view of the electronic device taken along line I-I'. Figure 1D These are cross-sectional views of electronic devices based on some exemplary embodiments of the inventive concept.

[0044] Reference Figures 1A to 1C The electronic device ED can be activated by an electrical signal. The electronic device ED can include various embodiments. For example, the electronic device ED can be applied to electronic devices such as smartwatches, tablet computers, laptop computers, personal computers, and smart TVs.

[0045] The electronic device ED can display an image IM on a display surface IS parallel to each of the first direction DR1 and the second direction DR2, facing a third direction DR3. The display surface IS on which the image IM is displayed can correspond to the front surface of the electronic device ED. The image IM can include still images and videos.

[0046] According to some example embodiments, the front (or top) surface and rear (or bottom) surface of each component are defined based on the direction along its displayed image IM. 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.

[0047] The spacing between the front and rear surfaces in the third direction DR3 can correspond to the thickness of the electronic device ED in the third direction DR3. Here, as a relative concept, the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 can be converted relative to each other.

[0048] An electronic device ED can sense external input applied from the outside. External input can include various types of input provided from the outside of the electronic device ED. According to some example embodiments of the inventive concept, the electronic device ED can sense a first input TC1 applied from the outside by a user US. The first input TC1 of the user US can be one of various types of external input, such as a part of the user's body, light, heat, pressure, or a combination thereof. Although the first input TC1 of the user US is described as a tactile input applied to the front surface caused by the user US's hand, embodiments according to the inventive concept are not limited thereto. For example, the first input TC1 of the user US can include various types. Furthermore, the electronic device ED can sense the first input TC1 of the user US applied to the side or rear surface of the electronic device ED, depending on the structure of the electronic device ED. However, embodiments according to the inventive concept are not limited thereto.

[0049] Furthermore, according to some example embodiments of the inventive concept, the electronic device ED can sense a second input TC2 applied from the outside. The second input TC2 may include input caused by an input device AP other than the user's hand (e.g., a stylus, active pen, touch pen, e-pen, etc.). Hereinafter, the second input TC2 will be described as an example input caused by an active pen.

[0050] The front surface of an electronic device ED can be divided into a transmissive region TA and a border region BZA. The transmissive region TA can be the area in which an image IM is displayed. The user can identify the image IM through the transmissive region TA. According to some example embodiments, the transmissive region TA has a rectangular shape with rounded vertices. However, this is merely illustrative. The transmissive region TA can have various shapes, and embodiments of the inventive concept are not limited to the shape of the transmissive region TA.

[0051] The border region BZA is positioned adjacent to the transmission region TA (e.g., around the periphery of the transmission region TA or outside the area occupied by the transmission region TA). The border region BZA may have a color (e.g., a set color or a predetermined color). The border region BZA defines the shape of the transmission region TA. Therefore, the transmission region TA may have a shape substantially defined by the border region BZA. The border region BZA may be positioned adjacent only to one side of the transmission region TA. However, according to some example embodiments, the border region BZA may be omitted. The electronic device ED according to some example embodiments of the inventive concept may include various embodiments and may not be limited to any one of them.

[0052] like Figure 1B As shown, the electronic device ED may include a display module DM and a window WM located on the display module DM. The display module DM may include a display panel DP and an input sensor ISP.

[0053] While the display panel DP according to some exemplary embodiments of the inventive concept may be a light-emitting display panel, the embodiments of the inventive concept are not specifically limited thereto. For example, the display panel DP may be an organic light-emitting display panel or a quantum dot light-emitting display panel. An organic light-emitting display panel may include a light-emitting layer comprising organic light-emitting materials. A quantum dot light-emitting display panel may include a light-emitting layer comprising quantum dots and quantum rods. Hereinafter, the display panel DP will be described as an organic light-emitting display panel.

[0054] Reference Figure 1C The input sensor ISP can be directly located on the display panel DP. According to some exemplary embodiments of the inventive concept, the input sensor ISP can be disposed on the display panel DP via a continuous process. That is, when the input sensor ISP is directly located on the display panel DP, the adhesive film may not be located between the input sensor ISP and the display panel DP. However, as... Figure 1D As shown, the inner adhesive film I_AF can be located between the input sensor ISP and the display panel DP. In this case, the input sensor ISP can be manufactured using a process separate from the display panel DP, and then fixed to the top surface of the display panel DP using the inner adhesive film I_AF, instead of being manufactured using a process continuous with the display panel DP.

[0055] The display panel (DP) generates an image, and the input sensor (ISP) acquires the coordinate information of external inputs (e.g., first input and second input).

[0056] The window WM can be made of a transparent material capable of transmitting images. For example, the window can be made of glass, sapphire, and plastic. Although the window WM is shown as a single layer in the drawings, embodiments according to the inventive concept are not limited thereto. For example, the window WM may include multiple layers. According to some example embodiments, the aforementioned border region BZA of the electronic device ED can be obtained by printing a material with a color (e.g., a set color or a predetermined color) onto a portion of the window WM. According to some example embodiments of the inventive concept, the window WM may include a light-shielding pattern WBM for defining the border region BZA. The light-shielding pattern WBM can be a colored organic layer and is applied by, for example, any suitable coating method.

[0057] The window WM can be bonded to the display module DM via an adhesive film AF. According to some exemplary embodiments of the inventive concept, the adhesive film AF may include an optically clear adhesive film (OCA). However, embodiments of the inventive concept are not limited to the adhesive film AF. For example, the adhesive film AF may include typical adhesives or adhesives. For example, the adhesive film AF may include an optically clear resin (OCR) or a pressure-sensitive adhesive film (PSA).

[0058] An anti-reflective layer can also be positioned between the window WM and the display module DM. The anti-reflective layer reduces the reflectivity of external light incident from above the window WM. According to some example embodiments of the inventive concept, the anti-reflective layer may include a retarder and a polarizer. The retarder may be a film-type or liquid crystal-coated type, and may include a λ / 2 retarder and / or a λ / 4 retarder. The polarizer may also be a film-type or liquid crystal-coated type. The film-type may include a flexible synthetic resin film, and the liquid crystal coating type may include liquid crystal (e.g., arranged in a set or predetermined arrangement). The retarder and polarizer may be implemented by a single polarizing film.

[0059] The display module DM can display images and transmit and receive information about external inputs based on electrical signals. The display module DM can be defined by an active area AA and a peripheral area NAA. The active area AA can be defined as the area that transmits images provided by the display module DM.

[0060] The peripheral region NAA is positioned adjacent to the effective region AA. For example, the peripheral region NAA may surround the effective region AA. The peripheral region NAA may have various shapes and is not limited to any shape according to embodiments of the inventive concept. According to some example embodiments, the effective region AA of the display module DM may correspond to at least a portion of the transmissive region TA.

[0061] The display module DM may further include a main circuit board (MCB), a flexible circuit film (FCB), and a driver chip (DIC). The main circuit board (MCB) can be connected to the flexible circuit film (FCB) and electrically connected to the display panel (DP). The main circuit board (MCB) may include multiple driving elements. The multiple driving elements may include circuit units for driving the display panel (DP). The flexible circuit film (FCB) can be connected to the display panel (DP) to electrically connect the display panel (DP) to the main circuit board (MCB). The driver chip (DIC) can be mounted on the flexible circuit film (FCB).

[0062] The driver chip (DIC) may include driving elements, such as data driving circuitry, for driving the pixels of the display panel (DP). While a flexible circuit film (FCB) is shown as an example embodiment according to some inventive concepts, embodiments according to the inventive concepts are not limited thereto. For example, multiple flexible circuit film FCBs may be configured and connected to the display panel (DP). Figure 1B The diagram illustrates the structure of a driver chip DIC mounted on a flexible circuit film FCB, but embodiments according to the inventive concept are not limited thereto. For example, according to some exemplary embodiments, the driver chip DIC can be directly mounted on the display panel DP. In this case, the portion of the display panel DP on which the driver chip DIC is mounted can be bent to position it on the rear surface of the display module DM.

[0063] The input sensor ISP can be electrically connected to the main circuit board MCB via a flexible circuit film FCB. However, embodiments according to the inventive concept are not limited to this. That is, the display module DM may additionally include a separate flexible circuit film for electrically connecting the input sensor ISP to the main circuit board MCB.

[0064] The electronic device ED may also include an outer housing EDC that houses the display module DM. The housing EDC may be combined with a window WM to define the appearance of the electronic device ED. The housing EDC absorbs impacts applied from the outside and prevents foreign objects / moisture from penetrating into the display module DM, thus protecting the components housed within the housing EDC. According to some exemplary embodiments of the inventive concept, the housing EDC can be configured by combining multiple housing members.

[0065] According to some example embodiments, the electronic device ED may also include an electronic module, a power module, and a bracket. The electronic module includes various functional modules for operating the display module DM. The power module supplies the power required for the overall operation of the electronic device ED. The bracket is combined with the display module DM and / or the housing EDC to divide the internal space of the electronic device ED.

[0066] Figure 2A This is a block diagram used to explain the operation of an electronic device according to some exemplary embodiments of the inventive concept. Figure 2B yes Figure 2A A block diagram of the input device in the diagram. Figure 3 This is a block diagram illustrating the construction of an input sensor and a sensor controller according to some exemplary embodiments of the inventive concept.

[0067] Reference Figure 2A , Figure 2B and Figure 3 Electronic devices ED (refer to some exemplary embodiments of the inventive concept) Figure 1B The system also includes a main controller 200 for controlling the drive of the display module DM and a sensor controller 100 connected to the input sensor ISP. The main controller 200 can be connected to the sensor controller 100 and control the drive of the sensor controller 100. According to some exemplary embodiments of the inventive concept, the main controller 200 and the sensor controller 100 can be mounted on the main circuit board MCB (see reference). Figure 1B Alternatively, according to some example embodiments, the sensor controller 100 may embed a driver chip DIC (see [reference]). Figure 1B )middle.

[0068] The input sensor ISP includes a first sensing electrode SE1 and a second sensing electrode SE2 electrically insulated from the first sensing electrode SE1. The first sensing electrode SE1 may both extend along a second direction DR2 and be arranged along a first direction DR1 intersecting the second direction DR2. The second sensing electrode SE2 may both extend along the first direction DR1 and be arranged along the second direction DR2. The first sensing electrode SE1 and the second sensing electrode SE2 may intersect each other and be capacitively coupled through the intersection portion.

[0069] Although each of the first sensing electrode SE1 and the second sensing electrode SE2 is in Figure 3 The image is shown as having a strip shape, but embodiments according to the inventive concept are not limited thereto. For example, each of the first sensing electrode SE1 and the second sensing electrode SE2 may include multiple grid lines.

[0070] The sensor controller 100 includes a first driver 120 connected to a first sensing electrode SE1 of the input sensor ISP and a second driver 130 connected to a second sensing electrode SE2 of the input sensor ISP. The sensor controller 100 may also include a control unit 110 for controlling the driving of the first driver 120 and the second driver 130.

[0071] The sensor controller 100 can operate the input sensor ISP to sense the first input TC1 of the user US, and communicate with the input device AP through the input sensor ISP to sense the second input TC2.

[0072] The input device AP may include a housing 11, a conductive pen tip 12, and a communication module 13. The housing 11 may have a pen shape including an internal receiving space. The conductive pen tip 12 may protrude to the outside from an open side of the housing 11. The conductive pen tip 12 may be the part of the input device AP that directly contacts the input sensor ISP.

[0073] The communication module 13 may include a transmission circuit 13a and a receiving circuit 13b. The transmission circuit 13a may transmit downlink signals to the sensor controller 100. The downlink signals may include the position of the input device AP, the tilt angle of the input device AP, status information, etc. When the input device AP contacts the input sensor ISP, the sensor controller 100 can receive the downlink signals through the input sensor ISP.

[0074] The receiving circuit 13b can receive uplink signals from the sensor controller 100. The uplink signals may include information such as panel information and protocol version. The sensor controller 100 can provide the uplink signals to the input sensor ISP, and the input device AP can receive the uplink signals by contacting the input sensor ISP.

[0075] The input device AP also includes an input controller 14 that controls the drive of the input device AP. The input controller 14 can operate according to a regulated program. The transmission circuit 13a receives signals supplied from the input controller 14 to modulate the received signals into signals that can be sensed by the input sensor ISP, and the receiving circuit 13b modulates the signals received by the input sensor ISP into signals that can be processed by the input controller 14.

[0076] The input device AP may also include a power module 15 for supplying power to the input device AP.

[0077] Figure 4A This is a conceptual diagram used to explain the operation at the first input sensing frame according to some exemplary embodiments of the inventive concept. Figure 4B This is a conceptual diagram used to explain the operation at the second input sensing frame according to some example embodiments of the inventive concept.

[0078] Reference Figures 2A to 4B The electronic device ED displays the image IM via a display panel DP. The display panel DP can display the image IM in units of one display frame DF. When the display panel DP has an operating frequency of approximately 120Hz, the time corresponding to one display frame DF can be approximately 8.33ms.

[0079] While the electronic device ED displays an image via the display panel DP, the electronic device ED senses a first input TC1 and a second input TC2. Depending on the presence of the input device AP, the electronic device ED can operate in a first input sensing mode that senses the first input TC1 or a second input sensing mode that senses the second input TC2. For example, when the input device AP is not sensed, the electronic device ED can operate in the first input sensing mode, while when the input device AP is sensed, the electronic device ED can operate in the second input sensing mode.

[0080] According to some exemplary embodiments of the inventive concept, the operating frequency of the input sensor ISP in the first input sensing mode and the second input sensing mode can be equal to or greater than the operating frequency of the display panel DP. For example, when the display panel DP has an operating frequency of approximately 120 Hz, the input sensor ISP can have an operating frequency of approximately 240 Hz. When the input sensor ISP operates in the first input sensing mode, it can sense the first input TC1 in units of a first input sensing frame IF1, while when the input sensor ISP operates in the second input sensing mode, it can sense the second input TC2 in units of a second input sensing frame IF2. Here, the time corresponding to each of the first input sensing frame IF1 and the second input sensing frame IF2 can be approximately 4.16 ms.

[0081] According to some exemplary embodiments of the inventive concept, when the input sensor ISP operates in a first input sensing mode, the input sensor ISP can sense the first input TC1 in both a first mode and a second mode. Here, the first mode can be defined as a self-capacitance operating mode of sensing the first input TC1 using either the first sensing electrode SE1 or the second sensing electrode SE2 of the input sensor ISP. The second mode can be defined as a mutual capacitance operating mode of sensing the first input TC1 when the first sensing electrode SE1 and the second sensing electrode SE2 of the input sensor ISP are capacitively coupled to each other.

[0082] During the first input sensing frame IF1, the input sensor ISP operates in a first input sensing mode. The first input sensing frame IF1 may include a first operating period OP1 and a second operating period OP2. The input sensor ISP may sense a first input TC1 in the first mode during the first operating period OP1 and sense the first input TC1 in the second mode during the second operating period OP2. According to some exemplary embodiments of the inventive concept, the second operating period OP2 may be located after the first operating period OP1 in the first input sensing frame IF1. Furthermore, the second operating period OP2 may have a longer time width than the first operating period OP1.

[0083] When the input sensor ISP operates in the first input sensing mode, the sensor controller 100 may transmit an integrated transmission signal TTS to the input sensor ISP during a first operation period OP1. The integrated transmission signal TTS may include an identification signal for identifying the input device AP, and a first mode sensing signal for sensing the first input TC1 in the first mode. That is, the first operation period OP1 may be defined as a first identification period for identifying the input device AP, and may be defined as a period for sensing the first input TC1 in the first mode.

[0084] The first input sensing frame IF1 also includes a first response period RP1 located between the first operation period OP1 and the second operation period OP2, for receiving an integrated reception signal TRS from the input sensor ISP. The integrated reception signal TRS may include identification information about the presence of the input device AP and sensing information for the first input TC1 sensed in the first mode.

[0085] The first delay period DE1 can be located between the first operation period OP1 and the first response period RP1. That is, the first response period RP1 can be separated from the first operation period OP1 by the first delay period DE1 in time.

[0086] When the input sensor ISP operates in the first input sensing mode, the sensor controller 100 can transmit a second mode sensing signal MS2 to the first sensing electrode SE1 of the input sensor ISP and receive a sensing reception signal MR2 from the second sensing electrode SE2 during the second operation period OP2. Therefore, the sensor controller 100 can enable the input sensor ISP to operate in the second mode during the second operation period OP2.

[0087] The first input sensing frame IF1 may also include a second delay period DE2 located after or following the second operation period OP2. That is, the second operation period OP2 can be completed, the second delay period DE2 can be delayed, and then the next first input sensing frame IF1 can begin.

[0088] According to some exemplary embodiments of the inventive concept, the processing frame PF may also be located temporally between two adjacent first input sensing frames IF1. The processing frame PF can process the signals sensed by the first input sensing frames IF1 to generate coordinate information. The processing frame PF may have the same time width as the first input sensing frames IF1. Furthermore, the processing frame PF may include a processing period PP and a third delay period DE3.

[0089] During the second input sensing frame IF2, the input sensor ISP operates in the second input sensing mode. The second input sensing frame IF2 may include a third operation period OP3 and a fourth operation period OP4.

[0090] The sensor controller 100 may transmit an identification signal RS for identifying the input device AP to the input sensor ISP during the third operation period OP3. That is, the third operation period OP3 in the second input sensing frame IF2 may be defined as a second identification period for identifying the input device AP. The signal transmitted to the input sensor ISP during the third operation period OP3 of the second input sensing frame IF2 may differ from the signal transmitted to the input sensor ISP during the first operation period OP1 of the first input sensing frame IF1. The signal transmitted to the input sensor ISP during the first operation period OP1 may be an integrated sensing signal TTS in which the identification signal and the first mode sensing signal are integrated, while the signal transmitted to the input sensor ISP during the third operation period OP3 may only include the identification signal.

[0091] Sensor controller 100 can transmit an uplink signal ULS to the input sensor ISP and receive a downlink signal DLS from the input sensor ISP during the fourth operating period OP4 to sense the second input TC2 input through the input device AP. That is, the fourth operating period OP4 in the second input sensing frame IF2 can be defined as the period for sensing the second input TC2 from the input device AP.

[0092] The second input sensing frame IF2 may also include a second response period RP2 located between the third operation period OP3 and the fourth operation period OP4, and receiving a response signal AS from the input device AP. The response signal AS may include identification information regarding the presence of the input device AP.

[0093] The fourth delay period DE4 can be located between the third operation period OP3 and the second response period RP2. That is, the second response period RP2 can be separated from the third operation period OP3 in time from the fourth delay period DE4.

[0094] The second input sensing frame IF2 may also include a fifth delay period DE5 following the fourth operation period OP4. That is, the fourth operation period OP4 can be completed, the fifth delay period DE5 can be delayed, and then the next second input sensing frame IF2 can begin.

[0095] As described above, when the input sensor ISP operates in the first input sensing mode, the identification operation of the input device AP and the first input sensing operation in the first mode can be performed simultaneously during the first operation period OP1 using the integrated transmission signal TTS. Therefore, the input sensor ISP can prevent the time allotted for sensing the first input TC1 from being reduced due to the time allocated for identifying the input device AP in the high-speed drive electronics ED. In other words, since the time allocated for identifying the input device AP can be used to sense the first input TC1, the input sensing performance of the input sensor ISP can be prevented from deteriorating during high-speed driving.

Figure 6 This is a block diagram illustrating the connection relationship between the first driver and the second driver and the control unit during a first operating period of the first input sensing frame, according to some example embodiments of the inventive concept. Figure 7A It means Figure 6 Waveforms of the identification signal, sensing signal, and integrated transmission signal in the image. Figure 7B It is a waveform diagram representing the integrated transmission signal accumulated during multiple first input sensing frames.

[0097] Reference Figure 3 and Figure 5 The input sensor ISP includes a first sensing electrode SE1 and a second sensing electrode SE2. The first sensing electrode SE1 and the second sensing electrode SE2 are electrically insulated from each other. According to some exemplary embodiments of the inventive concept, the first sensing electrode SE1 includes n first sensing electrodes SE1_1 to SE1_n, and the second sensing electrode SE2 includes m second sensing electrodes SE2_1 to SE2_m. Here, n and m are natural numbers equal to or greater than 1. Although n can be larger than m, the embodiments of the inventive concept are not limited thereto. That is, n can be equal to or less than m. In the following, for ease of description, n first sensing electrodes SE1_1 to SE1_n are referred to as first sensing electrodes SE1_1 to SE1_n, and m second sensing electrodes SE2_1 to SE2_m are referred to as second sensing electrodes SE2_1 to SE2_m.

[0098] First sensing electrodes SE1_1 to SE1_n are connected to a first driver 120, and second sensing electrodes SE2_1 to SE2_m are connected to a second driver 130. According to some exemplary embodiments of the inventive concept, the first driver 120 includes a first transmission unit 121, a first receiving unit 122, and a first switching unit 123. The second driver 130 includes a second transmission unit 131, a second receiving unit 132, and a second switching unit 133.

[0099] The first transmission unit 121 is connected to the control unit 110 and transmits signals received from the control unit 110 to the first sensing electrodes SE1_1 to SE1_n. The first receiving unit 122 receives signals from the first sensing electrodes SE1_1 to SE1_n and provides the received signals to the control unit 110. The first switching unit 123 selectively connects the first sensing electrodes SE1_1 to SE1_n to the first transmission unit 121 or the first receiving unit 122 in response to the first selection signal SS1 in a first state. For example, the first switching unit 123 may connect the first sensing electrodes SE1_1 to SE1_n to the first transmission terminals TT1_1 to TT1_n in response to the first selection signal SS1 in a first state, and connect the first sensing electrodes SE1_1 to SE1_n to the first receiving terminals RT1_1 to RT1_n in response to the first selection signal SS1 in a second state. The first transmission terminals TT1_1 to TT1_n may be terminals connected to the first transmission unit 121, and the first receiving terminals RT1_1 to RT1_n may be terminals connected to the first receiving unit 122.

[0100] The second transmission unit 131 is connected to the control unit 110 and transmits signals received from the control unit 110 to the second sensing electrodes SE2_1 to SE2_m. The second receiving unit 132 receives signals from the second sensing electrodes SE2_1 to SE2_m and provides the received signals to the control unit 110. The second switching unit 133, in response to the second selection signal SS2, selectively connects the second sensing electrodes SE2_1 to SE2_m to the second transmission unit 131 or the second receiving unit 132. For example, the second switching unit 133 may, in response to the second selection signal SS2 in the first state, connect the second sensing electrodes SE2_1 to SE2_m to the second transmission terminals TT2_1 to TT2_m, and in response to the second selection signal SS2 in the second state, connect the second sensing electrodes SE2_1 to SE2_m to the second receiving terminals RT2_1 to RT2_m. The second transmission terminals TT2_1 to TT2_m may be terminals connected to the second transmission unit 131, and the second receiving terminals RT2_1 to RT2_m may be terminals connected to the second receiving unit 132.

[0101] Reference Figure 2A , Figure 4A , Figure 5 and Figure 6 The control unit 110 includes an identification unit 111, a first input sensing unit 112, and an integrated signal generation unit 113.

[0102] The identification unit 111 outputs an identification signal RS for identifying the input device AP. During the first input sensing frame IF1, the identification signal RS output from the identification unit 111 can be provided to the integrated signal generation unit 113.

[0103] The first input sensing unit 112 may output a signal for sensing the first input TC1 during the first input sensing frame IF1. For example, the first input sensing unit 112 may output a first mode sensing signal MS1 for sensing the first input TC1 during the first operation period OP1 of the first input sensing frame IF1 in a first mode. The first mode sensing signal MS1 output from the first input sensing unit 112 during the first input sensing frame IF1 may be provided to the integrated signal generation unit 113.

[0104] The integrated signal generation unit 113 can generate an integrated transmission signal TTS by integrating the identification signal RS and the first mode sensing signal MS1, and provide the generated integrated transmission signal TTS to the first driver 120 and the second driver 130. For example, the integrated transmission signal TTS can be provided to the first transmission unit 121 of the first driver 120 and the second transmission unit 131 of the second driver 130. The integrated transmission signal TTS can be transmitted to the first sensing electrodes SE1_1 to SE1_n through the first transmission unit 121, and to the second sensing electrodes SE2_1 to SE2_m through the second transmission unit 131.

[0105] like Figure 7A As shown, the identification signal RS can be a digital signal represented by logic 0 and logic 1, and the first mode sensing signal MS1 can be an analog signal. According to some example embodiments of the inventive concept, the first mode sensing signal MS1 can be a voltage signal oscillating between approximately 0V and approximately 6V. The integrated signal generation unit 113 can generate an integrated transmission signal TTS oscillating between approximately 0V and approximately 6V based on the identification signal RS. However, embodiments of the inventive concept are not limited to the method of integrating the identification signal RS and the first mode sensing signal MS1. For example, different methods of integrating the identification signal RS and the first mode sensing signal MS1 can be provided. Furthermore, embodiments of the inventive concept are not limited to the amplitude of the voltage of the integrated transmission signal TTS. For example, the amplitude of the voltage of the integrated transmission signal TTS can be set differently.

[0106] The integrated transmission signal TTS can be transmitted to the input device AP via the input sensor ISP. The input device AP can receive the integrated transmission signal TTS and transmit an integrated reception signal TRS in response to the received integrated transmission signal TTS. The identification unit 111 can receive the integrated reception signal TRS from the input device AP via the input sensor ISP and determine whether the input device AP exists based on the received integrated reception signal TRS. When the identification unit 111 determines that the input device does not exist, the control unit 110 senses the first input TC1 via the first input sensing unit 112. However, when the identification unit 111 determines that the input device AP exists, the control unit 110 can sense the first input TC1 via the second input sensing unit 114 (see reference). Figure 9 )Sense the second input TC2.

[0107] The first input sensing unit 112 receives an integrated received signal TRS via an input sensor ISP, and senses the first input TC1 in a first mode based on the received integrated received signal TRS. According to some exemplary embodiments of the inventive concept, such as... Figure 7BAs shown, the first input sensing unit 112 can sense the first input TC1 by accumulating and integrating the integrated received signals TRS1 to TRSr received during a preset number (e.g., r, where r is a natural number greater than 1) of first input sensing frames IF1. The amplitude of the voltage of a portion of the integrated received signals TRS1 to TRSr can change due to the capacitance provided by the first input TC1 when sensing the first input TC1. The first input sensing unit 112 can sense the first input TC1 by reflecting the amplitude change ΔV (e.g., the amplitude change Δ1 of the integrated received signal TRS1 to TRSr) during several frames.

[0108] Figure 8 This is a block diagram illustrating the connection relationship between the first driver, the second driver, and the control unit during a second operating period of the first input sensing frame, according to some example embodiments of the inventive concept.

[0109] Reference Figure 2A , Figure 4A , Figure 5 and Figure 8 The first input sensing unit 112 can output a second mode sensing signal MS2 for sensing the first input TC1 in the second mode during the second operation period OP2 of the first input sensing frame IF1. The second mode sensing signal MS2 output from the first input sensing unit 112 during the first input sensing frame IF1 can be provided to the first transmission unit 121 of the first driver 120. During the second operation period OP2, the first input sensing unit 112 is not connected to the second transmission unit 131. Therefore, during the second operation period OP2, the second mode sensing signal MS2 can be provided to the first sensing electrodes SE1_1 to SE1_n of the input sensor ISP through the first transmission unit 121.

[0110] Furthermore, the first input sensing unit 112 receives the sensing reception signal MR2 transmitted from the input sensor ISP during the second operation period OP2. The first input sensing unit 112 receives the sensing reception signal MR2 via the second receiving unit 132 of the second driver 130. That is, the first input sensing unit 112 can be connected to the second receiving unit 132 and receives the sensing reception signal MR2 from the second sensing electrodes SE2_1 to SE2_m of the input sensor ISP during the second operation period OP2. During the second operation period OP2, the first input sensing unit 112 is not connected to the first transmission unit 121.

[0111] The first input sensing unit 112 can generate coordinate information about the first input TC1 based on the sensing and receiving signal MR2, and provide the generated coordinate information to the main controller 200.

[0112] Figure 9 This is a block diagram illustrating the connection relationship between the first driver, the second driver, and the control unit during a second input sensing frame, according to some example embodiments of the inventive concept.

[0113] Reference Figure 2A , Figure 4B , Figure 5 and Figure 9 When an input device AP exists based on the determination result of the identification unit 111, the control unit 110 can sense the second input TC2 through the second input sensing unit 114.

[0114] When the input sensor ISP operates in the second input sensing mode, the identification unit 111 outputs an identification signal RS for identifying the input device AP. During the third operation period OP3 of the second input sensing frame IF2, the identification signal RS output from the identification unit 111 can be transmitted to the first sensing electrodes SE1_1 to SE1_n of the input sensor ISP via the first transmission unit 121, and to the second sensing electrodes SE2_1 to SE2_m of the input sensor ISP via the second transmission unit 131.

[0115] The identification unit 111 can receive a response signal AS from the input device AP via the input sensor ISP, and determine whether the input device AP exists based on the received response signal AS. When the identification unit 111 determines that an input device exists, the control unit 110 senses the second input TC2 via the second input sensing unit 114. However, when the identification unit 111 determines that an input device does not exist, the control unit 110 can sense the second input TC2 via the first input sensing unit 112 (see reference 114). Figure 6 )Sense the first input TC1.

[0116] The second input sensing unit 114 performs data communication for sensing the second input TC2 during the fourth operation period OP4 of the second input sensing frame IF2. During the fourth operation period OP4, the second input sensing unit 114 outputs an uplink signal ULS, which is transmitted to the input sensor ISP via the first transmission unit 121 and the second transmission unit 131. When the input device AP is connected to the input sensor ISP, the uplink signal ULS is transmitted to the input device AP via the first sensing electrodes SE1_1 to SE1_n and the second sensing electrodes SE2_1 to SE2_m of the input sensor ISP. When the input device AP contacts the input sensor ISP to output a downlink signal DLS, the output downlink signal DLS is provided to the first receiving unit 122 and the second receiving unit 132 via the first sensing electrodes SE1_1 to SE1_n and the second sensing electrodes SE2_1 to SE2_m of the input sensor ISP. The second input sensing unit 114 receives the downlink signal DLS from the first receiving unit 122 and the second receiving unit 132, and senses the second input TC2 based on the downlink signal DLS.

[0117] The second input sensing unit 114 can generate coordinate information about the second input TC2 based on the downlink signal DLS or all types of functional information, and provide the generated information to the main controller 200.

Figure 11 This is a block diagram illustrating the construction of an input sensor and a sensor controller according to some exemplary embodiments of the inventive concept. Figure 12 It is shown Figure 11 Internal block diagram of the frequency adjustment unit.

[0119] Reference Figure 9 and Figure 10 Electronic devices ED (refer to) Figure 1B ) via display panel DP (refer to) Figure 1B Display image IM. The display panel DP can display image IM in units of display frames DF.

[0120] When the electronic device ED displays an image via the display panel DP, the electronic device ED can sense the first input TC1 (refer to...). Figure 2A ) and second input TC2 (refer to Figure 2A According to the input device AP (refer to...) Figure 2AWhether the input device AP is present or not, the electronic device ED can operate in a first input sensing mode that senses the first input TC1 or in a second input sensing mode that senses the second input TC2. Here, the state in which the second input TC2 of the input device AP is not sensed, even though it is present, can be referred to as a standby state. According to some example embodiments of the inventive concept, the electronic device ED can operate in a standby state in the above-mentioned standby state.

[0121] According to some exemplary embodiments of the inventive concept, the operating frequency of the input sensor ISP in the first input sensing mode and the second input sensing mode can be equal to or greater than the operating frequency of the display panel DP. For example, when the display panel DP has an operating frequency of approximately 120 Hz, the input sensor ISP can have an operating frequency of approximately 240 Hz. However, in standby mode, the input sensor ISP can have an operating frequency lower than that of the display panel DP.

[0122] Here, a detailed description of the operation of the input sensor ISP in the first and second input sensing modes will be omitted to avoid confusion with... Figure 4A and Figure 4B The situations in the text overlap.

[0123] When the input sensor ISP operates in standby mode, it can sense the first input TC1 or the second input TC2 in units of a hold frame HF. According to some example embodiments of the inventive concept, the input sensor ISP in standby mode can operate at an operating frequency of approximately 60 Hz, in which case the time corresponding to the hold frame HF can be approximately 16.7 ms.

[0124] The hold frame HF may include a fifth operation period OP5. During the fifth operation period OP5, the identification unit 111 outputs an identification signal RS for identifying the input device AP. During the fifth operation period OP5 of the hold frame HF, the identification signal RS can be transmitted via the first transmission unit 121 to the first sensing electrodes SE1_1 to SE1_n of the input sensor ISP and via the second transmission unit 131 to the second sensing electrodes SE2_1 to SE2_m of the input sensor ISP. The identification unit 111 receives a response signal AS from the input device AP via the input sensor ISP and determines whether the input device AP exists based on the received response signal AS.

[0125] Here, while the feature of determining the presence of an input device AP by transmitting an identification signal RS during a hold frame HF is shown as an example, embodiments of the inventive concept are not limited thereto. For example, according to some example embodiments, the presence of an input device AP can be determined by transmitting an integrated transmission signal TTS during a hold frame HF.

[0126] Reference Figure 11 and Figure 12 According to some example embodiments of the inventive concept, the sensor controller 100 may further include a frequency adjustment unit 140. The operating frequency of the input sensor ISP for each operating mode can be adjusted by the frequency adjustment unit 140.

[0127] The frequency adjustment unit 140 includes a determination unit 141 that determines whether the input device AP is in a standby state and a frequency setting unit 142 that outputs an adjustment signal HS for adjusting the operating frequency of the input sensor ISP based on the determination result. Although the frequency adjustment unit 140 and the control unit 110 are in... Figure 11 The components are shown as separate functional blocks, but embodiments of the inventive concept are not limited thereto. For example, the frequency adjustment unit 140 may be included in the control unit 110.

[0128] The frequency adjustment unit 140 can set the operating frequency of the input sensor ISP to a frequency lower than the reference frequency when the input device AP is in standby mode, and set the operating frequency of the input sensor ISP to the reference frequency when the input device AP is not in standby mode. When the input device AP is not in standby mode, the input sensor ISP can have an operating frequency set to the reference frequency and operate in a first input sensing mode and a second input sensing mode.

[0130] Reference Figure 13 and Figure 14 The display panel DP may include a drive circuit GDC, multiple signal lines SGL, and multiple pixels PX. The display panel DP may also include pad (or "solder pad") portions PLD located in the peripheral area NAA. The pad portions PLD include pixel pads D-PD, each connected to a corresponding signal line in one of the multiple signal lines SGL.

[0131] Pixel PX is located within the effective area AA. Each pixel PX includes an organic light-emitting diode (OLED) and a pixel driving circuit connected to the OLED.

[0132] The driving circuit GDC may include a gate driving circuit. The gate driving circuit generates multiple gate signals and sequentially outputs these gate signals to multiple gate lines GL, which will be described later. The gate driving circuit may also output another control signal to the pixel driving circuit.

[0133] The signal line SGL includes gate line GL, data line DL, power line PL, and control signal line CSL. One gate line in the gate line GL is connected to the corresponding pixel PX in the pixel PX, and one data line in the data line DL is connected to the corresponding pixel PX in the pixel PX. The power line PL is connected to pixel PX. The control signal line CSL provides control signals to the drive circuit GDC.

Pixel pads D-PD are connected to their respective pixels PX via signal lines SGL. Furthermore, one pixel pad in the pixel pads D-PD may be connected to the drive circuit GDC.

[0135] Reference Figure 14 The input sensor ISP according to some example embodiments of the inventive concept includes first sensing electrodes SE1_1 to SE1_5 and second sensing electrodes SE2_1 to SE2_4. The input sensor ISP may also include first traces SL1_1 to SL1_5 connected to one side of the first sensing electrodes SE1_1 to SE1_5 and second traces SL2_1 to SL2_4 connected to one side of the second sensing electrodes SE2_1 to SE2_4.

[0136] The first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4 intersect each other. A capacitor is disposed between the first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4. The capacitance between the first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4 can vary due to an external input (i.e., the first input TC1).

[0137] Each of the first sensing electrodes SE1_1 to SE1_5 includes a first sensor portion SP1 and a first connection portion CP1 located in the effective region AA. Each of the second sensing electrodes SE2_1 to SE2_4 includes a second sensor portion SP2 and a second connection portion CP2 located in the effective region AA.

[0138] Although Figure 14 The illustration shows a first sensor portion SP1 and a second sensor portion SP2, both having a rhomboid shape, but embodiments of the inventive concept are not limited thereto. For example, each of the first sensor portion SP1 and the second sensor portion SP2 may have a different polygonal shape.

[0139] A first sensor portion SP1 is arranged in a first sensing electrode on a second direction DR2, and a second sensor portion SP2 is arranged in a second sensing electrode on a first direction DR1. Each of the first connecting portions CP1 connects adjacent first sensor portions SP1 to each other, and each of the second connecting portions CP2 connects adjacent second sensor portions SP2 to each other.

[0140] The first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4 can have a grid shape. Because the first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4 have a grid shape, the contact between the first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4 and the display panel DP (refer to...) can be reduced. Figure 13 The parasitic capacitance generated by the electrodes.

[0141] The first sensing electrodes SE1_1 to SE1_5 and the second sensing electrodes SE2_1 to SE2_4, which have a grid shape, may include materials such as silver, aluminum, copper, chromium, nickel, and titanium, which can be processed in low-temperature processes. However, embodiments of the inventive concept are not limited thereto. Even if the input sensor ISP is provided through a continuous process, the organic light-emitting diode will not be damaged.

[0142] First traces SL1_1 to SL1_5 are respectively connected to one end of the first sensing electrodes SE1_1 to SE1_5. According to some exemplary embodiments of the inventive concept, the input sensor ISP may further include traces respectively connected to the other ends of the first sensing electrodes SE1_1 to SE1_5. Second traces SL2_1 to SL2_4 are respectively connected to one end of the second sensing electrodes SE2_1 to SE2_4. According to some exemplary embodiments of the inventive concept, the input sensor ISP may further include traces respectively connected to the other ends of the second sensing electrodes SE2_1 to SE2_4.

[0143] The first traces SL1_1 to SL1_5 and the second traces SL2_1 to SL2_4 may be located in the peripheral region NAA. The input sensor ISP may include input pads I-PDs extending from one end of the first traces SL1_1 to SL1_5 and the second traces SL2_1 to SL2_4 and located in the peripheral region NAA. The input pads I-PDs include a first input pad IPD1 connected to the first traces SL1_1 to SL1_5 and a second input pad IPD2 connected to the second traces SL2_1 to SL2_4.

[0144] When the input sensor senses the first input and the second input, the electronic device according to some example embodiments of the inventive concept can perform the two operations simultaneously by using an integrated signal obtained by integrating an identification signal for identifying the input device with a sensing signal for sensing the first input during a portion of a first input sensing frame that senses the first input.

[0145] Therefore, since the input sensor can sense the first input during the time period allocated for identifying the input device in the high-speed driving electronic device, the degradation of the input sensing performance of the input sensor during high-speed driving can be prevented or reduced.

[0146] While exemplary embodiments of the invention have been described, it is understood that the invention should not be limited to these exemplary embodiments, but rather that various changes and modifications can be made by those skilled in the art within the spirit and scope of the invention claimed below.
