In this case, the sensor layer (200) may be described as being placed directly on the display layer (100). Being placed directly means that no third component is placed between the sensor layer (200) and the display layer (100). That is, a separate adhesive member may not be placed between the sensor layer (200) and the display layer (100). Alternatively, the sensor layer (200) may be bonded to the display layer (100) through an adhesive member. The adhesive member may include a conventional adhesive or a pressure-sensitive adhesive.

[0097] The display layer (100) may be defined as a display area (DA) and a non-display area (NDA). The display area (DA) may be defined as an area where an image (IM, see FIG. 1a) is displayed (i.e., an area where the image is displayed). The non-display area (NDA) is adjacent to the display area (DA). The non-display area (NDA) may be an area where the image (IM, see FIG. 1a) is not substantially displayed. For example, the non-display area (NDA) may surround the display area (DA). However, this is illustrated as an example, and the non-display area (NDA) may be defined in various shapes and is not limited to any one embodiment.

For example, the data driving circuit (100C3) may be formed by the same process as the circuit layer (120, see FIG. 3b) within the display layer (100).

[0105] FIG. 5 is a block diagram of a sensor layer and a sensor driving unit according to an embodiment of the present invention.

[0106] Referring to FIG. 5, the sensor layer (200) may include a touch sensor (200C4) and a pressure sensor (200C5). The touch sensor (200C4) and the pressure sensor (200C5) may be activated according to an electrical signal. For example, the touch sensor (200C4) may detect a touch input (TC, see FIG. 2), and the pressure sensor (200C5) may detect pressure. The touch sensor (200C4) may be placed in a first sensing area (SA1), and the pressure sensor (200C5) may be placed in a second sensing area (SA2). In one example of the present invention, the first sensing area (SA1) may overlap with the display area (DA, see FIG. 1a) of the electronic device (1000, see FIG. 1a), and the second sensing area (SA2) may overlap with the non-display area (NDA, see FIG. 1a) of the electronic device (1000). The second sensing area (SA2) can surround the first sensing area (SA1).

[0107] The sensor layer (200) may include a sensing electrode (SE). The sensing electrode (SE) may include a touch sensing electrode (TSE) and a pressure sensing electrode (PSE). The touch sensing electrode (TSE) may be included in the touch sensor (200C4) and may be placed in the first sensing area (SA1). The touch sensing electrode (TSE) may be provided in plurality, and the plurality of touch sensing electrodes (TSE) may include a plurality of first touch sensing electrodes (210) and a plurality of second touch sensing electrodes (220). Each of the plurality of first touch sensing electrodes (210) extends along a first direction (DR1), and the plurality of first touch sensing electrodes (210) may be spaced apart from each other in a second direction (DR2). Each of the plurality of second touch sensing electrodes (220) extends along a second direction (DR2), and the plurality of second touch sensing electrodes (220) may be spaced apart from each other in a first direction (DR1). A plurality of second touch sensing electrodes (220) can be insulated and crossed with each of a plurality of first touch sensing electrodes (210).

[0108] A pressure sensing electrode (PSE) may be included in a pressure sensor (200C5) and may be placed in a second sensing area (SA2). A plurality of pressure sensing electrodes (PSE) may be provided, and the plurality of pressure sensing electrodes (PSE) may include a plurality of first pressure sensing electrodes (230) and a plurality of second pressure sensing electrodes (240). Each of the plurality of first pressure sensing electrodes (230) may extend along a first direction (DR1), and each of the plurality of second pressure sensing electrodes (240) may extend along a second direction (DR2). As an example of the present invention, FIG. 5 illustrates a pressure sensing electrode (PSE) comprising two first pressure sensing electrodes (230) and two second pressure sensing electrodes (240). In this case, the first pressure sensing electrodes (230) may be spaced apart from each other in a second direction (DR2) with the touch sensing electrode (TSE) in between, and the second pressure sensing electrodes (240) may be spaced apart from each other in a first direction (DR1) with the touch sensing electrode (TSE) in between. However, the present invention is not limited thereto, and the pressure sensing electrode (PSE) may include one first pressure sensing electrode (230) and one second pressure sensing electrode (240).

[0109] The sensor driving unit (200C) can control the driving of the sensor layer (200). The sensor driving unit (200C) receives a sensor control signal (I-CS) from a processor (1000C, see FIG. 2) and can provide a coordinate signal (I-SS) to the processor (1000C).

[0110] The sensor driving unit (200C) may include a sensor control circuit (200C1), a signal generation circuit (200C2), and an input detection circuit (200C3). The sensor control circuit (200C1), the signal generation circuit (200C2), and the input detection circuit (200C3) may be implemented within a single chip, or some of the sensor control circuit (200C1), the signal generation circuit (200C2), and the input detection circuit (200C3) and others may be implemented within different chips.

[0111] The sensor control circuit (200C1) controls the operation of the signal generation circuit (200C2) and can calculate the coordinates of the external input and the pressure of the external input from the detection signal received from the input detection circuit (200C3), or analyze information transmitted from an external device from the modulation signal received from the input detection circuit (200C3).

[0112] The signal generation circuit (200C2) can provide a driving signal (TX) (or output signal) to the sensor layer (200). The signal generation circuit (200C2) can output a driving signal (TX) corresponding to a sensing frame to the sensor layer (200).

[0113] The input detection circuit (200C3) can receive a detection signal (RX) (or a received signal) from the sensor layer (200). The detection signal (RX) may be an analog signal. The input detection circuit (200C3) can amplify the received analog signal and then filter it. The input detection circuit (200C3) can then convert the filtered signal into a digital signal. For example, the input detection circuit (200C3) can convert the detection signal (RX) into sensing data (SD) and output it to the sensor control circuit (200C1).

[0114] FIG. 6 is a block diagram of a sensor control circuit according to one embodiment of the present invention.

[0115] Referring to FIGS. 2 and FIGS. 6, the sensor control circuit (200C1) may include a receiving unit (IU), a pressure determining unit (PU), and a transmitting unit (OU).

[0116] The receiver (IU) can receive sensing data (SD) from an input detection circuit (200C3, see FIG. 5). In one example of the present invention, the sensing data (SD) may include a touch sensing value (TS) and a pressure sensing value (PRS). The touch sensing value (TS) may include information regarding the coordinates of the input, and the pressure sensing value (PRS) may include information regarding the pressure of the input. The receiver (IU) can determine whether the touch sensing value (TS) included in the sensing data (SD) is greater than or equal to a preset touch threshold. The touch threshold may be a reference value for determining whether an input has occurred. If the receiver (IU) determines that the touch sensing value (TS) is greater than or equal to the touch threshold, the receiver (IU) may determine that an input exists in the sensor layer (200). In this case, the receiver (IU) may output the pressure sensing value (PRS) included in the sensing data (SD) to the pressure determination unit (PU). If the receiver (IU) determines that the touch sensing value (TS) is less than the touch threshold, the receiver (IU) may determine that there is no input. In this case, the receiver (IU) may not output the pressure sensing value (PRS) to the pressure determination unit (PU).

[0117] The pressure determination unit (PU) can receive a pressure sensing value (PRS) from the receiving unit (IU). The pressure determination unit (PU) can determine whether the pressure sensing value (PRS) is greater than or equal to a preset pressure threshold. The pressure threshold may be a reference value for determining whether an input has occurred. In this embodiment, if the pressure determination unit (PU) determines that the pressure sensing value (PRS) is greater than or equal to the pressure threshold, the input may be determined to be a touch input (TC) by the user's body (2000). In this case, the pressure determination unit (PU) can immediately output a start signal (INT) to the transmitting unit (OU). If the pressure determination unit (PU) determines that the pressure sensing value (PRS) is less than the pressure threshold, the input may be determined to be a noise input (NC) caused by spike noise (2100). In this case, the pressure determination unit (PU) can output a start signal (INT) to the transmitting unit (OU) after a preset delay time.

[0118] The transmitting unit (OU) can receive sensing data (SD) from the receiving unit (IU). Alternatively, as an example of the present invention, it can receive a touch sensing value (TS). Additionally, the transmitting unit (OU) may receive a start signal (INT) immediately or after a preset delay time, depending on the judgment result of the pressure judgment unit (PU). When the transmitting unit (OU) receives the start signal (INT), the transmitting unit (OU) is activated and can generate a coordinate signal (I-SS) based on the sensing data (SD, or touch sensing value (TS)) received at the time of activation. The coordinate signal (I-SS) may further include the start signal (INT). The transmitting unit (OU) can output the coordinate signal (I-SS) to the processor (1000C).

[0119] FIG. 7a is a block diagram of a sensor layer and a sensor driving unit according to an embodiment of the present invention. FIG. 7b is a timing diagram for explaining the operation of an electronic device according to an embodiment of the present invention.

[0120] Referring to FIGS. 2, FIGS. 7a, and FIGS. 7b, the touch sensor (200C4) detects a touch input (TC) by the user's body (2000), and the pressure sensor (200C5) can detect pressure. FIG. 7a illustrates the touch input (TC) being input to the sensor layer (200) at the start of the first sensing frame (SF1).

[0121] The sensor driving unit (200C) can drive the sensor layer (200) in units of sensing frames (SF0, SF1, SF2) to detect a touch input (TC). The sensing frames (SF0 to SF2) may have a driving frequency of 120 Hz (Hertz). That is, the sensing frames (SF0 to SF2) may be generated at a period of 8.3 ms (millisecond). However, this is exemplary, and the driving frequency of the sensing frames (SF) according to one embodiment of the present invention is not limited thereto. In this embodiment, three sensing frames (the zeroth sensing frame (SF0), the first sensing frame (SF1), and the second sensing frame (SF2)) are illustrated as examples.

[0122] Each of the sensing frames (SF0 to SF2) may include a scanning section (SS0, SS1, SS2) and a processing section (PS0, PS1, PS2). During the scanning section (SS0 to SS2), the sensor layer (200) may receive a driving signal (TX) from the sensor driving unit (200C), and the sensor driving unit (200C) may receive a detection signal (RX) from the sensor layer (200). In one example of the present invention, the driving signal (TX) may include a touch driving signal (TTX) and a pressure driving signal (PTX), and the detection signal (RX) may include a touch detection signal (TRX) and a pressure detection signal (PRX). The touch detection electrode (TSE) may receive the touch driving signal (TTX) from the sensor driving unit (200C) and output the touch detection signal (TRX) to the sensor driving unit (200C). The pressure sensing electrode (PSE) receives a pressure driving signal (PTX) from the sensor driving unit (200C), and the pressure sensing electrode (PSE) can output a pressure sensing signal (PRX) to the sensor driving unit (200C).

[0123] Sensing data (SD) can be generated during the processing interval (PS0 to PS2). The sensing data (SD) may include a touch sensing value (TS) and a pressure sensing value (PRS). During the processing interval (PS0 to PS2), the sensor driving unit (200C) can generate a touch sensing value (TS) based on a touch detection signal (TRX) and generate a pressure sensing value (PRS) based on a pressure detection signal (PRX). During the processing interval (PS0 to PS2), the receiving unit (IU, see FIG. 6) can compare the touch sensing value (TS) with a touch threshold value, and the pressure determination unit (PU, see FIG. 6) can compare the pressure sensing value (PRS) with a pressure threshold value. Depending on the comparison result, it may be determined whether to transmit a coordinate signal (I-SS) to the processor (1000C).

[0124] A touch input (TC) may occur at an input time point (IP). The input time point (IP) may be an intermediate time point of the 0th sensing frame (SF0). In this case, the sensor driver (200C) may not detect the touch input (TC) during the 0th scanning interval (SS0), and the sensor driver (200C) may not process information regarding the touch input (TC) during the 0th processing interval (PS0). If the input time point (IP) corresponds to an intermediate time point of the 0th sensing frame (SF0), the sensor driver (200C) may proceed with the detection and processing of the touch input (TC) starting from the sensing time point (SP). In one embodiment of the present invention, the 0th sensing frame (SF0) may be omitted.

[0125] The sensing time (SP) may be the start time of the first sensing frame (SF1). During the first scan interval (SS1), the sensor layer (200) receives a driving signal (TX) from the sensor driving unit (200C), and the sensor driving unit (200C) may receive a detection signal (RX) from the sensor layer (200). During the first processing interval (PS1), the sensor driving unit (200C) may generate sensing data (SD) based on the detection signal (RX). Additionally, during the first processing interval (PS1), the sensor driving unit (200C) may determine whether the input is a normal input by the user's body (2000) based on the sensing data (SD). As in the embodiment illustrated in FIG. 7a and FIG. 7b, when the input input to the sensor layer (200) does not include noise input (NC) caused by spike noise (2100) and includes only touch input (TC) caused by the user's body (2000), the first sensing frame (SF1) may be an active frame (AF).

[0126] After the active frame (AF) is terminated, a second sensing frame (SF2) may be initiated. During the second sensing frame (SF2), an initiation signal (INT) is activated, and the sensor driver (200C) may output a coordinate signal (I-SS) to the processor (1000C). The coordinate signal (I-SS) may include the initiation signal (INT) and sensing data (SD) generated during the active frame (AF). The processor (1000C) may receive the sensing data (SD) from the sensor driver (200C) in response to the activated initiation signal (INT).

[0127] The first delay time (DT1) can be defined as the time required for the sensor driver (200C) to detect the touch input (TC) after the touch input (TC) occurs and to output a coordinate signal (I-SS) to the processor (1000C). In this embodiment, one sensing frame (SF1) may be included during the first delay time (DT1).

[0128] According to the present invention, as in the embodiment illustrated in FIG. 7a and FIG. 7b, when the pressure determination unit (PU) determines that the pressure sensing value (PRS) is greater than the pressure threshold value, the input input to the sensor layer (200) may be determined to include only the touch input (TC) by the user's body (2000) and not the noise input (NC) caused by the spike noise (2100). In this embodiment, in this case, a coordinate signal (I-SS) containing the sensing data (SD) generated during the first sensing frame (SF1) may be output to the processor (1000C) without setting a separate holding frame. Accordingly, an electronic device with improved response speed may be provided.

[0129] FIGS. 8A and 8B are block diagrams of a sensor layer and a sensor driving unit according to an embodiment of the present invention. FIG. 8C is a timing diagram for explaining the operation of an electronic device according to an embodiment of the present invention.

[0130] Referring to FIGS. 2, FIGS. 8a, FIGS. 8b, and FIGS. 8c, a touch sensor (200C4) detects a touch input (TC) by the user's body (2000) and a noise input (NC) by spike noise (2100), and a pressure sensor (200C5) can detect pressure. FIG. 8a illustrates the detection of a touch input (TC) by the user's body (2000) and a noise input (NC) by spike noise (2100) at the start of the first sensing frame (SF1), and FIG. 8b illustrates the detection of a touch input (TC) by the user's body (2000) at the start of the n+1 sensing frame (SFn+1). In one example of the present invention, the noise input (NC) may be an input caused by a single-shot noise that occurs rapidly for a very short period of time due to the touch input (TC). The embodiments illustrated in FIGS. 8a, 8b, and 8c include the same configuration as the embodiments illustrated in FIGS. 7a and 7b, except that noise input (NC) is generated by touch input (TC). Therefore, the same reference numerals are used for identical configurations, and redundant descriptions are omitted.

[0131] The sensor driving unit (200C) can drive the sensor layer (200) in units of sensing frames (SF0, SF1-SFn, SFn+1, SFn+2) to detect input. In this embodiment, n+3 sensing frames (SF0-SFn+2) are illustrated as an example.

[0132] As illustrated in FIG. 8a, the input time point (IP) may be an intermediate time point of the 0th sensing frame (SF0), and the sensing time point (SP) may be the start time point of the 1st sensing frame (SF1). At the input time point (IP), a touch input (TC) is input to the sensor layer (200), and from the sensing time point (SP), detection and processing of the touch input (TC) and the noise input (NC) caused by spike noise (2100) may be performed. During the first scan interval (SS1), the sensor layer (200) receives a driving signal (TX) from the sensor driving unit (200C), and the sensor driving unit (200C) may receive a detection signal (RX) from the sensor layer (200). During the first processing interval (PS1), the sensor driving unit (200C) may generate sensing data (SD) based on the detection signal (RX). Additionally, the sensor driving unit (200C) can determine whether the touch input (TC) and the noise input (NC) are normal inputs by the user's body (2000) based on the sensing data (SD) during the first processing interval (PS1). As in the embodiment illustrated in FIGS. 8a and 8b, if the input includes a noise input (NC) caused by spike noise (2100), the first to nth sensing frames (SF1-SFn) may be holding frames (HF). Since spike noise (2100) is noise that persists for a short period of time, the noise input (NC) can be removed after n holding frames (HF) have elapsed.

[0133] After n holding frames (HF) are terminated, the n+1 sensing frame (SFn+1) may be initiated. The n+1 sensing frame (SFn+1) may be an active frame (AF). As illustrated in FIG. 8b, during the n+1 sensing frame (SFn+1), only touch input (TC) by the user's body (2000) is input to the sensor layer (200), and spike noise (2100) is removed so that noise input (NC) caused by spike noise (2100) is not input. During the active frame (AF), sensing data (SD) may be generated based on the touch input (TC) by the user's body (2000). That is, the sensing data (SD) generated during the active frame (AF) may not include information regarding noise input (NC).

[0134] After the active frame (AF) is terminated, the n+2 sensing frame (SFn+2) may be initiated. During the n+2 sensing frame (SFn+2), an initiation signal (INT) is activated, and the sensor driver (200C) may output a coordinate signal (I-SS) to the processor (1000C). The coordinate signal (I-SS) may include the initiation signal (INT) and sensing data (SD) generated during the active frame (AF). The processor (1000C) may receive the sensing data (SD) from the sensor driver (200C) in response to the activated initiation signal (INT).

[0135] The second delay time (DT2) can be defined as the time required from when a touch input (TC) occurs until the sensor driver (200C) detects the touch input (TC) and outputs a coordinate signal (I-SS) to the processor (1000C). Since the second delay time (DT2) includes a holding frame (HF), the second delay time (DT2) may be longer than the first delay time (DT1, FIG. 7b).

[0136] In this embodiment, n+1 sensing frames (SF1-SFn+1) may be included during the second delay time (DT2). Here, n sensing frames (SF1-SFn) may be holding frames (HF), and the n+1th sensing frame (SFn+1) may be an active frame (AF). The holding frames (HF) may precede the active frames (AF). After the holding frames (HF) end, the coordinate signal (I-SS) may not be output to the processor (1000C). After the active frames (AF) end, the coordinate signal (I-SS) may be output to the processor (1000C). That is, the sensing data (SD) generated during the holding frames (HF) is not output to the processor (1000C), and the sensing data (SD) generated during the active frames (AF) may be output to the processor (1000C).

[0137] According to the present invention, as in the embodiment illustrated in FIGS. 8a, 8b, and 8c, when the pressure determination unit (PU) determines that the pressure sensing value (PRS) is smaller than the pressure threshold value, the input input to the sensor layer (200) may be determined to include a noise input (NC) caused by spike noise (2100). In this case, n holding frames (HF) may be set to delay time until a coordinate signal (I-SS) is output to the processor (1000C) after the touch input (TC). Accordingly, a coordinate signal (I-SS) containing information regarding the input from which noise has been removed may be output to the processor (1000C).

[0138] FIG. 9 is a flowchart illustrating an electronic device driving method according to one embodiment of the present invention.

[0139] Referring to FIGS. 6, FIGS. 7b, FIGS. 8c and FIGS. 9, a receiver (IU) can receive sensing data (SD) generated during a first sensing frame (SF1) (S100). The sensing data (SD) may include a touch sensing value (TS) and a pressure sensing value (PRS). The receiver (IU) can determine whether the touch sensing value (TS) included in the sensing data (SD) is greater than a preset touch threshold (S200). If the receiver (IU) determines that the touch sensing value (TS) is smaller than the touch threshold, it can determine that no input has been detected. If the receiver (IU) determines that the touch sensing value (TS) is greater than the touch threshold, it can determine that an input has been detected. In this case, the receiver (IU) can output the sensing data (SD) to a pressure determination unit (PU). The pressure determination unit (PU) can determine whether the pressure sensing value (PRS) included in the sensing data (SD) is greater than a preset pressure threshold (S300). If the pressure determination unit (PU) determines that the pressure sensing value (PRS) is greater than the pressure threshold, it can transmit a coordinate signal (I-SS) to a processor (1000C, see FIG. 2) (S400). In this case, the first sensing frame (SF1) may be an active frame (AF), and the coordinate signal (I-SS) may include the sensing data (SD) received during step S100.

[0140] If the pressure determination unit (PU) determines that the pressure sensing value (PRS) is less than the pressure threshold value, it may set n holding frames (HF) after the touch input (S500). After n holding frames (HF), an active frame (AF) may be initiated (S600). Subsequently, a coordinate signal (I-SS) may be transmitted to the processor (1000C) (S400). In this case, the coordinate signal (I-SS) may include sensing data (SD) generated during step S600.
