Description

Electronic device including a touch fingerprint integrated sensor, method of operating the same, and recording medium

[0001] Embodiments of the present disclosure relate to an electronic device including a touch fingerprint integrated sensor, a method of operating the same, and a recording medium.

[0002] An electronic device may refer to a device that performs a specified function according to a program installed in, for example, a home appliance, an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC (personal computer), a video / audio device, a desktop / laptop computer, or a vehicle navigation system.

[0003] An electronic device may include a touch sensor (e.g., a touch screen) for detecting a user's touch (e.g., a finger touch). The electronic device may include a fingerprint sensor (e.g., an optical fingerprint sensor) for detecting a user's fingerprint. The electronic device may be capable of operating each of the touch sensor (e.g., the touch screen) and the fingerprint sensor (e.g., the optical fingerprint sensor).

[0004] The information described above is provided solely as background information (related art) to aid in understanding the embodiments of the present disclosure. No determination has been made, and no claim has been made, as to whether any of the above information constitutes prior art in connection with the present disclosure.

[0005] A typical electronic device may include a touch sensor for touch detection and a fingerprint sensor (e.g., an optical fingerprint sensor) for fingerprint detection. Touch sensing operations using the touch sensor and fingerprint sensing operations using the fingerprint sensor may be performed separately. The fingerprint authentication function of an electronic device may be frequently performed when an application is running, and may be essential for the security and user authentication of the electronic device. Recently, flexible electronic devices including flexible displays (e.g., rollable displays) whose screen size can be expanded (or reduced) have been developed.

[0006] As the screen of a flexible display (e.g., a rollable display) expands (or contracts), there may be limitations in the placement of a fingerprint sensor on the flexible electronic device.

[0007] A fingerprint sensor may be fixedly positioned at the bottom of a flexible display (e.g., a rollable display). In this case, for the convenience of fingerprint authentication, the fingerprint must be sensed at a fixed location. However, as the screen of the flexible display (e.g., a rollable display) expands (or contracts), the location of the fingerprint sensor may also change. As the screen of the flexible display (e.g., a rollable display) expands (or contracts), the location of the fingerprint sensing may change, which may cause inconvenience to the user. In addition, the fingerprint must be sensed over the entire screen area of ​​the flexible display (e.g., a rollable display). However, if the fingerprint sensor is fixedly positioned at the bottom of the flexible display (e.g., a rollable display), there is a limitation that the fingerprint can only be sensed at a specific part of the screen.

[0008] The present disclosure addresses at least the problems and / or disadvantages mentioned above and provides at least the advantages described below. Embodiments of the present disclosure may provide an electronic device including a touch fingerprint integrated sensor capable of performing touch sensing and fingerprint sensing simultaneously by embedding a sensor (e.g., a touch fingerprint integrated sensor) that integrates touch sensing and fingerprint sensing functions into a display (e.g., an in-cell touch method), and a method of operating the same.

[0009] An embodiment of the present disclosure may provide an electronic device including a touch fingerprint integrated sensor capable of displaying a user interface for fingerprint authentication at a preset location regardless of screen expansion or reduction of a flexible display (e.g., a rollable display) and sensing a touch and fingerprint at the preset location, and a method of operating the same.

[0010] Another embodiment of the present disclosure may provide an electronic device including a touch fingerprint integrated sensor capable of sensing a fingerprint on the entire screen (e.g., the entire area of ​​the display) of a flexible display (e.g., a rollable display) and a method of operating the same.

[0011] Additional aspects will be partly explained in the following description, and partly will be apparent from the description or may be learned by practicing the examples provided.

The memory may store one or more computer programs. The one or more computer programs may include computer-executable instructions. When the instructions are executed by the one or more processors during a touch sensing operation, the electronic device may group the Tx lines in units of a certain number to configure a plurality of Tx touch channels, and supply a first Tx signal to the plurality of Tx touch channels. When the above instructions are executed by the above processor, the electronic device can, during a touch sensing operation, group the Rx lines in units of a certain number to configure a plurality of Rx channels, and receive a first Rx signal of each of the plurality of Rx channels. When the above instructions are executed by the one or more processors, the electronic device can, during a touch sensing operation, detect a touch position based on the first Rx signal of each of the plurality of Rx channels.

[0013] An electronic device according to an embodiment of the present disclosure may include a display having a plurality of pixels arranged thereon, a display driver IC (integrated circuit) for controlling an operation of the display, a touch fingerprint sensor arranged inside the display and including Tx lines and Rx lines formed of a metal mesh, a touch sensor IC for controlling an operation of the touch fingerprint sensor, and one or more processors for controlling the operations of the display driver IC and the touch fingerprint sensor IC. The display may include a light-blocking layer defining an area of ​​the plurality of pixels, and circuit wirings for driving the plurality of pixels. The plurality of pixels and the touch fingerprint sensor may be arranged so as not to overlap in the vertical direction. The touch fingerprint sensor and the light-blocking layer may be arranged so as to overlap in the vertical direction.

[0014] In an operating method of an electronic device including a touch fingerprint sensor according to an embodiment of the present disclosure, during a touch sensing operation, Tx lines may be grouped in units of a certain number to configure a plurality of Tx touch channels, and a first Tx signal may be supplied to the plurality of Tx touch channels. In the operating method, during a touch sensing operation, Rx lines may be grouped in units of a certain number to configure a plurality of Rx channels, and a first Rx signal of each of the plurality of Rx channels may be received. In the operating method, during a touch sensing operation, a touch position may be detected based on the first Rx signal of each of the plurality of Rx channels.

[0015] One or more non-transitory computer-readable recording media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device, cause the electronic device to perform an operation, wherein, during a touch sensing operation, Tx lines arranged on a display of the electronic device are grouped in units of a predetermined number to form a plurality of Tx touch channels, and a first Tx signal is supplied to the plurality of Tx touch channels. During the touch sensing operation, Rx lines arranged on the display are grouped in units of a predetermined number to form a plurality of Rx channels, and a first Rx signal of each of the plurality of Rx channels is received. During the touch sensing operation, a touch position can be detected based on the first Rx signal of each of the plurality of Rx channels. During a fingerprint sensing operation, a second Tx signal can be supplied to each of local Tx lines corresponding to the touch position among all of the Tx lines. During a fingerprint sensing operation, a second Rx signal of each of the local Rx lines corresponding to the touch location among all of the Rx lines can be received. During a fingerprint sensing operation, a fingerprint image can be generated based on the second Rx signal of each of the local Rx lines.

[0016] An electronic device including a touch fingerprint integrated sensor according to various embodiments of the present disclosure and an operating method thereof can perform touch sensing and fingerprint sensing together by embedding a sensor (e.g., a touch fingerprint integrated sensor) having an integrated touch sensing function and a fingerprint sensing function in a flexible display (e.g., a rollable display) (e.g., an in-cell touch method).

[0017] An electronic device including a touch fingerprint integrated sensor according to various embodiments of the present disclosure and a method of operating the same can display a user interface for fingerprint authentication at a preset location and sense a fingerprint at the preset location regardless of screen expansion or reduction of a flexible display (e.g., a rollable display).

The digitizer (460) may transmit the digital coordinate data to a processor (e.g., the processor (120) of FIG. 1) and / or a DDI (430).

[0203] According to one embodiment, the processor (120, 1250) may obtain (e.g., receive) digital coordinate data input from the digitizer (460). The processor (120, 1250) may detect an input (e.g., a touch input or a hovering input) through an electronic pen (e.g., a stylus pen) based on the digital coordinate data. For example, the digitizer (460) may include a plurality of x-axis channels and a plurality of y-axis channels.

For example, a digitizer (460) may have a plurality of x-axis channels and a plurality of y-axis channels sequentially arranged, and a processor (120, 1250) may sense the position of an electronic pen (e.g., a stylus pen) using sensing signals received from a plurality of consecutive channels (e.g., three adjacent channels).

[0204] In one embodiment, the digitizer (460) may be hidden from the outside by the display (410), electronic components, and mechanisms.

[0205] For example, the digitizer (460) may be disposed integrally with the flat display (410) or disposed adjacent to the flat display (410). For example, when the digitizer (460) is applied to the flat display (410), the digitizer (460) may include one EMR (electro magnetic resonance) sheet (or EMR film). A plurality of x-axis channels and a plurality of y-axis channels for detecting the position of the electronic pen may be disposed on one EMR sheet.

[0211] For example, the first metal mesh lines (622) may be formed as a metal pattern in a mesh shape (e.g., a metal mesh pattern (941) of FIG. 10 (e.g., a metal line in a mesh shape).

[0212] For example, the second metal mesh line (624) may be formed as a metal pattern in a mesh shape (e.g., a metal mesh pattern (941) of FIG. 10 (e.g., a metal line in a mesh shape).

[0213] For example, the width of each of the first metal mesh lines (622) and the second metal mesh lines (624) may be formed to be several micrometers.

[0217] For example, a certain number (e.g., two or more) of first metal mesh lines (622) can be grouped (e.g., electrically tied) to form respective first channels (712) (e.g., y channels) (e.g., Tx channels).

[0218] For example, each of the second metal mesh lines (624) can be configured to form second channels (714) (e.g., x channels) (e.g., Rx channels). That is, one second channel (714) (e.g., x channel) (e.g., Rx channel) can be configured with one second metal mesh line (624).

[0219] For example, a certain number (e.g., two or more) of second metal mesh lines (624) can be grouped (e.g., electrically tied) to form respective second channels (714) (e.g., x channels) (e.g., Rx channels).

[0220] For example, when a user's finger (720) comes into proximity of (or touches) a display (610) (e.g., a rollable display, a flexible display), a capacitance formed between a first channel (712) (e.g., a y channel) (e.g., a Tx channel) and a second channel (714) (e.g., an x ​​channel) (e.g., an Rx channel) may change. A touch sensor IC (e.g., a touch fingerprint sensor IC (453) of FIG. 4) may be used to detect a change in the capacitance formed between the first channel (712) (e.g., a y channel) (e.g., a Tx channel) and the second channel (714) (e.g., an x ​​channel) (e.g., an Rx channel).

[0221] For example, a touch sensor IC (e.g., a touch fingerprint sensor IC (453) of FIG. 4) can generate a touch value based on a capacitance between a first channel (712) (e.g., a y channel) (e.g., a Tx channel) and a second channel (714) (e.g., an x ​​channel) (e.g., an Rx channel). The touch sensor IC (e.g., a touch fingerprint sensor IC (453) of FIG. 4) can provide the touch value to a processor (e.g., a processor (120) of FIG. 1, a processor (1250) of FIG. 12). The processor (120, 1250) can detect a touch location (a location on a screen of a display where a touch was made) based on the acquired touch value.

[0223] FIG. 8b is a drawing showing a display in which sub-pixels are arranged in a diamond type according to one embodiment of the present disclosure.

[0224] FIG. 8c is a drawing showing a display in which sub-pixels are arranged in a round diamond type according to one embodiment of the present disclosure.

[0225] Referring to FIG. 8A, a display (810) (e.g., display (610) of FIGS. 6 and 7, display (900) of FIGS. 9 and 10) (e.g., rollable display, flexible display) may include a plurality of pixels (814) and a light-blocking layer (816) (e.g., light-absorbing layer) (e.g., black matrix).

[0226] According to one embodiment, the plurality of pixels (814) may be arranged in a stripe type. For example, each of the plurality of pixels (814) may be composed of sub-pixels (812) of three colors (e.g., red, green, and blue). However, the present invention is not limited thereto, and each of the plurality of pixels (814) may be composed of sub-pixels (812) of four or five colors. For example, the sub-pixels (812) may be separated (e.g., distinguished) by a light-blocking layer (816) (e.g., a light-absorbing layer) (e.g., a black matrix) to prevent color mixing.

[0227] Referring to FIG. 8b, a display (820) (e.g., display (610) of FIGS. 6 and 7, display (900) of FIGS. 9 and 10) (e.g., rollable display, flexible display) may include a plurality of pixels (824) and a light-blocking layer (826) (e.g., light-absorbing layer) (e.g., black matrix).

[0228] According to one embodiment, the plurality of pixels (824) may be arranged in a diamond type. For example, each of the plurality of pixels (824) may be composed of sub-pixels (822) of three colors (e.g., red, green, and blue). The diamond type may be such that the plurality of pixels (824) are arranged in a diamond shape (or a shape similar to a diamond), and the sizes of the sub-pixels (822) of the three colors (e.g., red, green, and blue) may be different. The present invention is not limited thereto, and each of the plurality of pixels (824) may be composed of sub-pixels (822) of four or five colors. For example, the sub-pixels (822) may be separated (e.g., distinguished) by a light-blocking layer (826) (e.g., a light-absorbing layer) (e.g., a black matrix) to prevent color mixing.

[0229] Referring to FIG. 8c, a display (830) (e.g., display (610) of FIGS. 6 and 7, display (900) of FIGS. 9 and 10) (e.g., rollable display, flexible display) may include a plurality of pixels (834) and a light-blocking layer (836) (e.g., light-absorbing layer) (e.g., black matrix).

[0230] For example, the plurality of pixels (834) may be arranged in a round diamond type. For example, each of the plurality of pixels (834) may be composed of sub-pixels (832) of three colors (e.g., red, green, and blue). The round diamond type may include a plurality of pixels (834) having a round shape arranged in a diamond shape (or a shape similar to a diamond), and the sizes of the sub-pixels (832) of the three colors (e.g., red, green, and blue) may be different. The present invention is not limited thereto, and each of the plurality of pixels (834) may be composed of sub-pixels (832) of four or five colors. For example, the sub-pixels (832) may be separated (e.g., distinguished) by a light-blocking layer (836) (e.g., a light-absorbing layer) (e.g., a black matrix) to prevent color mixing.

[0231] According to one embodiment, a display (840) (e.g., display (610) of FIGS. 6 and 7, display (900) of FIGS. 9 and 10) (e.g., rollable display, flexible display) may include a plurality of pixels (844) and a light-blocking layer (846) (e.g., light-absorbing layer) (e.g., black matrix).

[0232] For example, the plurality of pixels (844) may be arranged in a round diamond type. For example, each of the plurality of pixels (844) may be composed of sub-pixels (842) of three colors (e.g., red, green, and blue). The round diamond type may include a plurality of pixels (844) having a circular (or oval) shape arranged in a diamond shape (or a shape similar to a diamond), and the sizes of the sub-pixels (842) of the three colors (e.g., red, green, and blue) may be different. The present invention is not limited thereto, and each of the plurality of pixels (844) may be composed of sub-pixels (842) of four or five colors. For example, the sub-pixels (842) may be separated (e.g., distinguished) by a light-blocking layer (846) (e.g., a light-absorbing layer) (e.g., a black matrix) to prevent color mixing.

[0233] FIG. 9 is a cross-sectional view illustrating a display including a touch fingerprint integrated sensor according to an embodiment of the present disclosure. FIG. 10 is a diagram illustrating the arrangement of a touch fingerprint sensor and subpixels in an electronic device (e.g., the electronic device (200) of FIG. 2A) according to an embodiment of the present disclosure.

[0234] Referring to FIGS. 9 and 10, a display (900) (e.g., a rollable display, a flexible display) including a touch fingerprint integrated sensor according to an embodiment of the present disclosure may include a substrate (910), a plurality of sub-pixels (920) (e.g., the sub-pixels (920) of FIG. 11) disposed on the substrate (910), circuits and wires (930) for driving the pixels (920), a touch fingerprint sensor (940) (e.g., the touch fingerprint sensor (451) of FIG. 4) for sensing a touch and a fingerprint (e.g., a touch fingerprint integrated sensor), and a light-blocking layer (950) (e.g., a light-absorbing layer) (e.g., a black matrix).

[0235] According to one embodiment, the sub-pixels (920) may include organic light emitting diodes (OLEDs) or micro LEDs.

[0236] According to one embodiment, the plurality of sub-pixels (920) and the touch fingerprint sensor (940) may be arranged separately (e.g., not overlapping) on ​​a plane.

[0237] For example, the plurality of sub-pixels (920) and the touch fingerprint sensor (940) are arranged so as not to interfere with each other, so that the touch fingerprint sensor (940) does not affect the light emission of the plurality of sub-pixels (920).

[0238] For example, a plurality of sub-pixels (920) and a touch fingerprint sensor (940) are arranged so as not to interfere with each other, so that the plurality of sub-pixels (920) do not affect the operation of the touch fingerprint sensor (940).

[0239] According to one embodiment, the touch fingerprint sensor (940) and the light-blocking layer (950) (e.g., the light-absorbing layer) (e.g., the black matrix) may be arranged to overlap on a plane. For example, the touch fingerprint sensor (940) and the light-blocking layer (950) (e.g., the light-absorbing layer) (e.g., the black matrix) may be arranged to overlap in the z-axis (e.g., the z-axis of FIG. 2A, the z-axis of FIG. 3A). For example, the light-blocking layer (950) (e.g., the light-absorbing layer) (e.g., the black matrix) may be arranged to overlap on the upper part (e.g., above) of the touch fingerprint sensor (940) based on the direction in which the screen is displayed (e.g., the z-axis direction). For example, the light-blocking layer (950) (e.g., the light-absorbing layer) (e.g., the black matrix) may be arranged to cover at least the entirety of the touch fingerprint sensor (940) (e.g., to overlap at least the entirety of the touch fingerprint sensor).

[0240] For example, since the touch fingerprint sensor (940) is built into the interior of the display (900) (e.g., a rollable display, a flexible display) (or is placed on the top of the display (900)), it may not affect the transmittance of the display (900).

[0241] For example, since the touch fingerprint sensor (940) is positioned to overlap with a light-blocking layer (950) (e.g., a light-absorbing layer) (e.g., a black matrix), the moire phenomenon caused by the metal mesh pattern (941) of the touch fingerprint sensor (940) can be prevented from occurring.

[0242] According to one embodiment, the touch fingerprint sensor (940) may include first metal mesh lines (942) (e.g., the first metal mesh lines (622) of FIG. 6) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) formed of a metal mesh pattern (941) (e.g., a mesh-shaped metal pattern) (e.g., a mesh-shaped metal line) and second metal mesh lines (944) (e.g., the second metal mesh lines (624) of FIG. 6) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern).

[0243] For example, the display (900) (e.g., rollable display, flexible display) may be formed with a thickness of several tens of μm, so that a sensing distance for touch sensing and fingerprint sensing (e.g., obtaining a fingerprint image) can be secured.

[0244] According to one embodiment, the touch fingerprint sensor (940) is a sensor that integrates a touch sensing function and a fingerprint sensing function (e.g., a touch fingerprint integrated sensor) and can be built into a display (900) (e.g., a rollable display, a flexible display) (e.g., an in-cell touch method).

[0245] For example, when manufacturing a display (900) (e.g., a rollable display, a flexible display), a touch fingerprint sensor (940) may be formed while forming a plurality of sub-pixels (920) and / or circuits and wires (930), thereby embedding the touch fingerprint sensor (940) inside the display (900) (e.g., a rollable display, a flexible display) (e.g., an in-cell touch method).

[0246] For example, a touch fingerprint sensor (940) may be placed on the top (or surface) of a display (900) (e.g., a rollable display, a flexible display) in an on cell manner.

[0247] For example, in an electronic device according to an embodiment of the present disclosure, a touch fingerprint sensor (940) may be disposed on an upper portion (e.g., above the sub-pixels (920)) of a display (900) (e.g., a rollable display, a flexible display). The touch fingerprint sensor (940) may be disposed on an upper portion (e.g., above the sub-pixels (920)) of a display (900) (e.g., a rollable display, a flexible display), thereby increasing the sensitivity of touch sensing and fingerprint sensing.

[0248] Without being limited thereto, an electronic device according to an embodiment of the present disclosure may have a touch fingerprint sensor (940) positioned at the same height (or a similar height) as the sub-pixels (920).

[0249] According to one embodiment, the metal mesh pattern (941) (e.g., a mesh-shaped metal line) forming the touch fingerprint sensor (940) may be formed of a metal having low electrical resistance and high electric conductivity (e.g., silver (Ag), copper (Cu), gold (Au), aluminum (Al), magnesium (Mg), zinc (Zn), nickel (Ni), lead (Pb), antimony (Sb)). For example, the metal mesh pattern (941) (e.g., a mesh-shaped metal line) forming the touch fingerprint sensor (940) may be formed of an alloy including at least two of silver (Ag), copper (Cu), gold (Au), aluminum (Al), magnesium (Mg), zinc (Zn), nickel (Ni), lead (Pb), and antimony (Sb).

[0250] FIG. 11 is a drawing showing a first metal mesh line (e.g., a Tx metal mesh line) and a second metal mesh line (e.g., an Rx metal mesh line) arranged in a display according to one embodiment of the present disclosure.

[0251] Referring to FIGS. 10 and 11, a display (900) (e.g., a rollable display, a flexible display) according to an embodiment of the present disclosure may include a plurality of sub-pixels (920) and a touch fingerprint sensor (940) (e.g., the touch fingerprint sensor (451) of FIG. 4).

[0252] According to one embodiment, the touch fingerprint sensor (940) may include first metal mesh lines (942) (e.g., the first metal mesh lines (622) of FIG. 6) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) formed of a mesh-shaped metal pattern (e.g., the metal mesh pattern (941) of FIG. 10) (e.g., a mesh-shaped metal line), and second metal mesh lines (944) (e.g., the second metal mesh lines (624) of FIG. 6) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., an Rx metal mesh pattern).

[0253] For example, the first metal mesh lines (942) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) can be used as Tx lines for touch sensing and fingerprint sensing (e.g., Tx touch fingerprint sensing lines).

[0254] For example, the second metal mesh lines (944) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern) can be used as Rx lines for touch sensing and fingerprint sensing (e.g., Rx touch fingerprint sensing lines).

[0255] For example, the first metal mesh lines (942) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) may be arranged in a line shape (e.g., metal mesh line shape) having a length in a first direction (e.g., y-axis direction). Without being limited thereto, the first metal mesh lines (942) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) may be arranged in a line shape (e.g., metal mesh line shape) having a length in a second direction (e.g., x-axis direction).

[0256] For example, the second metal mesh lines (944) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern) may be arranged in a line shape (e.g., metal mesh line shape) having a length in a second direction (e.g., x-axis direction) orthogonal to the first direction (e.g., y-axis direction). Without being limited thereto, the second metal mesh lines (944) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern) may be arranged in a line shape (e.g., metal mesh line shape) having a length in the first direction (e.g., y-axis direction).

[0257] For example, first metal mesh lines (942) (e.g., Tx metal mesh lines) can be formed by electrically connecting first metal mesh patterns (942a).

[0258] For example, the first metal mesh patterns (942a) can be electrically connected by first connection wires (960) (e.g., first metal mesh connection wires) (e.g., first metal mesh connection pattern).

[0259] For example, second metal mesh lines (944) (e.g., Rx metal mesh lines) can be formed by electrically connecting second metal mesh patterns (944a).

[0260] For example, the second metal mesh patterns (944a) can be electrically connected by second connecting wires (970) (e.g., second metal mesh connecting wires) (e.g., second metal mesh connecting pattern).

[0261] According to one embodiment, the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the second metal mesh lines (944) (e.g., Rx metal mesh lines) may be arranged on different planes. For example, the first metal mesh lines (942) (e.g., Tx metal mesh lines) may be arranged in a first layer, and the second metal mesh lines (944) (e.g., Rx metal mesh lines) may be arranged in a second layer. An insulating layer may be arranged between the first layer and the second layer.

[0262] According to one embodiment, the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the second metal mesh lines (944) (e.g., Rx metal mesh lines) may be arranged in the same plane (e.g., substantially in the same plane).

[0263] For example, when first metal mesh lines (942) (e.g., Tx metal mesh lines) and second metal mesh lines (944) (e.g., Rx metal mesh lines) are arranged on the same plane (e.g., substantially the same plane), a bridge pattern (980) may be arranged at a portion where the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the second metal mesh lines (944) (e.g., Rx metal mesh lines) intersect.

[0264] For example, the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the second metal mesh lines (944) (e.g., Rx metal mesh lines) can be electrically disconnected (e.g., disconnected) from each other (e.g., insulated) through the bridge pattern (980).

[0265] For example, the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the bridge pattern (980) may be electrically connected so that the first metal mesh lines (942) (e.g., Tx metal mesh lines) and the second metal mesh lines (944) (e.g., Rx metal mesh lines) are not electrically connected (e.g., separated) (e.g., insulated).

[0266] Without being limited thereto, the second metal mesh lines (944) (e.g., Rx metal mesh lines) and the bridge pattern (980) may be electrically connected so that the two metal mesh lines (944) (e.g., Rx metal mesh lines) and the first metal mesh lines (942) (e.g., Tx metal mesh lines) are not electrically connected (e.g., separated) (e.g., insulated).

[0267] FIG. 12 is a diagram illustrating an electronic device including a touch fingerprint integrated sensor according to an embodiment of the present disclosure. FIG. 13 is a diagram (1300) illustrating first switching waveforms of a first multiplexer (e.g., a Tx multiplexer) and second switching waveforms of a second multiplexer (e.g., an Rx multiplexer) for touch recognition according to an embodiment of the present disclosure.

[0268] Referring to FIGS. 12 and 13, an electronic device (1200) according to an embodiment of the present disclosure may include a display (900) having a plurality of pixels arranged thereon (e.g., a rollable display, a flexible display), a display driver IC (e.g., a display driver IC (430) of FIG. 4), a first multiplexer (1220) (e.g., a Tx multiplexer), a second multiplexer (1230) (e.g., an Rx multiplexer), a touch fingerprint sensor IC (1240) (e.g., a touch fingerprint sensor IC (453) of FIG. 4), a processor (1250) (e.g., the processor (120) of FIG. 1), and a memory (130) (e.g., the memory (130) of FIG. 1).

[0269] According to one embodiment, the processor (1250) and the memory (130) may be operatively connected. The memory (130) may include instructions for executing the processor (1250), the display driver IC (430), and the touch fingerprint sensor IC (1240).

[0270] According to one embodiment, the processor (1250) may be operatively connected to a display driver IC (430) and a touch fingerprint sensor IC (1240). For example, the processor (1250) may control the operation of the display driver IC (430). For example, the processor (1250) may control the operation of the touch fingerprint sensor IC (1240).

[0271] For example, the processor (1250) can control the operation of a first multiplexer (1220) (e.g., a Tx multiplexer) and a second multiplexer (1230) (e.g., an Rx multiplexer).

[0272] According to one embodiment, the display driver IC (430) can operate the display (900) (e.g., rollable display, flexible display) based on the control of the processor (1250).

[0273] According to one embodiment, the display (900) may include a touch fingerprint sensor (1210) (e.g., a touch fingerprint sensor (940) of FIGS. 9 to 11) (e.g., a touch fingerprint integrated sensor) arranged to perform touch sensing and fingerprint sensing together. An electronic device (1200) according to one embodiment of the present disclosure may perform touch sensing and fingerprint sensing together by using a touch fingerprint sensor (1210, 940) (e.g., a touch fingerprint integrated sensor).

[0274] According to one embodiment, the touch fingerprint sensor IC (1240) can operate the touch fingerprint sensor (1210, 940) based on the control of the processor (1250).

[0275] For example, the touch fingerprint sensor (1210, 940) may include first metal mesh lines (e.g., first metal mesh lines (942) of FIGS. 10 and 11) formed of a mesh-shaped metal pattern (e.g., metal mesh pattern (941) of FIG. 10 (e.g., metal lines in a mesh shape)) and second metal mesh lines (e.g., second metal mesh lines (944) of FIGS. 10 and 11).

[0276] For example, the first metal mesh lines (942) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) can be used as Tx lines (e.g., Tx touch fingerprint sensing lines) for touch sensing and fingerprint sensing. For example, the first metal mesh lines (942) (e.g., first conductive mesh lines) (e.g., first mesh touch lines) (e.g., Tx metal mesh lines) (e.g., Tx metal mesh pattern) can be driven individually.

[0277] For example, the second metal mesh lines (944) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern) can be used as Rx lines (e.g., Rx touch fingerprint sensing lines) for touch sensing and fingerprint sensing. For example, the second metal mesh lines (944) (e.g., second conductive mesh lines) (e.g., second mesh touch lines) (e.g., Rx metal mesh lines) (e.g., Rx metal mesh pattern) can be driven individually.

[0278] According to one embodiment, an electronic device (1200) according to one embodiment of the present disclosure can perform touch sensing and fingerprint sensing together by using first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) and second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) disposed (e.g., built into) a display (900) (e.g., a rollable display, a flexible display).

[0279] An electronic device (1200) according to an embodiment of the present disclosure can perform touch sensing operations and fingerprint sensing operations separately. For example, the electronic device (1200) can perform touch sensing operations and fingerprint sensing operations simultaneously (e.g., substantially simultaneously). For example, the electronic device (1200) can perform the touch sensing operation first and then the fingerprint sensing operation. For example, the electronic device (1200) can start the fingerprint sensing operation before the touch sensing operation is completed. For example, the electronic device (1200) can start the fingerprint sensing operation after the touch sensing operation is completed.

[0280] An electronic device (1200) according to an embodiment of the present disclosure may configure a plurality of Tx touch channels (1212) by grouping a certain number of first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) during a touch sensing operation. For example, a processor (1250) may control the operation of a first multiplexer (1220) (e.g., Tx multiplexer). The first multiplexer (1220) (e.g., Tx multiplexer) may electrically connect or insulate a touch fingerprint sensor IC (1240) and the first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines).

[0281] For example, the first multiplexer (1220) (e.g., a Tx multiplexer) may include a plurality of first switches (e.g., a plurality of Tx selection switches). For example, the first multiplexer (1220) (e.g., a Tx multiplexer) may group the plurality of first switches (e.g., a plurality of Tx selection switches) in units of a certain number so that the first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) are grouped in units of a certain number and supply the first switch signals (1310).

[0282] For example, a plurality of first switches (e.g., a plurality of Tx selection switches) of a first multiplexer (1220) (e.g., a Tx multiplexer) may be selectively turned on or off by the first switch signals (1310). The plurality of first switches (e.g., a plurality of Tx selection switches) may be selectively turned on or off to electrically connect or electrically insulate each of the first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) from the touch fingerprint sensor IC (1240).

[0283] For example, a first multiplexer (1220) (e.g., a Tx multiplexer) may group (e.g., electrically connect) a certain number of first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) to form a plurality of Tx touch channels (1212) (e.g., TXG1, TXG2, …, TXGn).

[0284] For example, the touch fingerprint sensor IC (1240) can supply a first Tx signal (e.g., a first Tx signal for touch sensing) to a first multiplexer (1220) (e.g., a Tx multiplexer).

[0285] For example, a first multiplexer (1220) (e.g., a Tx multiplexer) may supply a first Tx signal (e.g., a first Tx signal for touch sensing) to a plurality of Tx touch channels (1212) (e.g., TXG1, TXG2, …, TXGn) in which first metal mesh lines (942) (e.g., Tx lines) (e.g., Tx touch fingerprint sensing lines) are grouped (e.g., electrically connected) in units of a certain number. For example, the same first Tx signal (e.g., a first Tx signal for touch sensing) may be supplied to each of the plurality of Tx touch channels (1212) (e.g., TXG1, TXG2, …, TXGn).

[0286] According to an embodiment of the present disclosure, the electronic device (1200) may group a certain number of second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) to configure a plurality of Rx touch channels (1214) during a touch sensing operation. For example, the processor (1250) may control the operation of the second multiplexer (1230) (e.g., Rx multiplexer). The second multiplexer (1230) (e.g., Rx multiplexer) may electrically connect or insulate the touch fingerprint sensor IC (1240) and the second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines).

[0287] For example, the second multiplexer (1230) (e.g., Rx multiplexer) may include a plurality of second switches (e.g., a plurality of Rx selection switches). For example, the second multiplexer (1230) (e.g., Rx multiplexer) may group a plurality of second switches (e.g., a plurality of Rx selection switches) in a predetermined number of units so that the second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) are grouped in a predetermined number of units and supply the second switch signals (1320).

[0288] For example, a plurality of second switches (e.g., a plurality of Rx selection switches) of a second multiplexer (1230) (e.g., an Rx multiplexer) may be selectively turned on or off by the second switch signals (1320). The plurality of second switches (e.g., a plurality of Rx selection switches) may be selectively turned on or off to electrically connect or electrically insulate each of the second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) from or to the touch fingerprint sensor IC (1240).

[0289] For example, the second multiplexer (1230) (e.g., Rx multiplexer) can group (e.g., electrically connect) the second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) in units of a certain number to form each of a plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn). For example, the second multiplexer (1230) (e.g., Rx multiplexer) can receive a first Rx signal (e.g., a first Rx signal for touch sensing) from a plurality of Rx touch channels (1214) (e.g., RXG1, rXG2, …, RXGn) in which the second metal mesh lines (944) (e.g., Rx lines) (e.g., Rx touch fingerprint sensing lines) are grouped (e.g., electrically connected) in units of a certain number. A second multiplexer (1230) (e.g., an Rx multiplexer) can transfer (e.g., provide, transmit) a first Rx signal (e.g., a first Rx signal for touch sensing) received from a plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn) to a touch fingerprint sensor IC (1240).

[0290] For example, while one Tx touch channel (1212) is driven (e.g., while one Tx touch channel (1212) is supplied with a first Tx signal (e.g., a first Tx signal for touch sensing)), a first Rx signal (e.g., a first Rx signal for touch sensing) can be detected for all Rx touch channels (1214). The waveform scale of the Tx touch channel (1212) and the waveform scale of the Rx touch channels (1214) may be different.

[0291] According to one embodiment, the touch fingerprint sensor IC (1240) may include a touch controller (1242) and an analog-to-digital converter (1244).

[0292] An analog-to-digital converter (1244) can convert a first Rx signal (e.g., a first Rx signal for touch sensing) received from a plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn) into digital first touch values.

[0293] For example, the touch controller (1242) can determine a touch location (1260) (e.g., a location where a touch was made) based on the touch values ​​of each of the plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn).

[0294] For example, the touch controller (1242) can provide (e.g., transmit, transfer) the touch values ​​of each of the plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn) to the processor (1250). The processor (1250) can determine the touch location (1260) (e.g., the location where the touch was made) based on the touch values ​​of each of the plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn).

[0295] According to one embodiment of the present disclosure, the display (900) (e.g., a rollable display, a flexible display) of an electronic device (1200) can be slid in a first direction (e.g., direction ① of FIG. 2A) to expand the screen (e.g., a pull-out state of the rollable display).

[0296] According to one embodiment of the present disclosure, the display (900) (e.g., a rollable display, a flexible display) of the electronic device (1200) can be slid in a second direction (e.g., direction ② of FIG. 2A) so that the screen can be reduced (e.g., a retracted state of the rollable display).

[0297] An electronic device (1200) according to an embodiment of the present disclosure can determine, when a touch sensing operation is performed, whether the display (900) (e.g., a rollable display, a flexible display) is in an expanded screen state (e.g., an extended screen state of the rollable display) or a contracted screen state (e.g., an in-short screen state of the rollable display). For example, the processor (1250) can determine, using a sensor module (e.g., a sensor module (176) of FIG. 1), whether the display (900) (e.g., a rollable display, a flexible display) is in an expanded screen state (e.g., an extended screen state of the rollable display) or a contracted screen state (e.g., an in-short screen state of the rollable display).

[0298] An electronic device (1200) according to an embodiment of the present disclosure may configure a plurality of Tx touch channels (1212) (e.g., TXG1, TXG2, …, TXGn) according to the expanded state (e.g., the pulled-out state) of the display (900) (e.g., the rollable display, the flexible display) when the display (900) (e.g., the rollable display, the flexible display) is in an expanded state (e.g., the pulled-out state of the rollable display).

[0299] An electronic device (1200) according to an embodiment of the present disclosure may configure a plurality of Rx touch channels (1214) (e.g., RXG1, RXG2, …, RXGn) according to the expanded state (e.g., the pulled-out state) of the display (900) (e.g., the rollable display, the flexible display) when the display (900) (e.g., the rollable display, the flexible display) is in an expanded state (e.g., the pulled-out state of the rollable display).

[0300] An electronic device (1200) according to an embodiment of the present disclosure can sense a fingerprint (1262) by using first metal mesh lines (942) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made) during a fingerprint sensing operation.

[0301] An electronic device (1200) according to an embodiment of the present disclosure can sense a fingerprint (1262) by using second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made) during a fingerprint sensing operation.

[0302] According to one embodiment, the processor (1250) can control the operation of the first multiplexer (1220) (e.g., Tx multiplexer). The first multiplexer (1220) (e.g., Tx multiplexer) can individually turn on or off the first metal mesh lines (942) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) arranged at the touch location (1260) (e.g., the location where the touch is made).

[0303] For example, the touch fingerprint sensor IC (1240) can supply a second Tx signal (e.g., a second Tx signal for fingerprint sensing) to the first multiplexer (1220) (e.g., a Tx multiplexer).

[0304] For example, a first multiplexer (1220) (e.g., a Tx multiplexer) can supply a second Tx signal (e.g., a second Tx signal for fingerprint sensing) to first metal mesh lines (942) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made).

[0305] In an electronic device (1200) according to an embodiment of the present disclosure, when a fingerprint sensing operation is performed, a processor (1250) can control the operation of a second multiplexer (1230) (e.g., an Rx multiplexer). The second multiplexer (1230) (e.g., an Rx multiplexer) can individually turn on or off second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made).

[0306] For example, a node (e.g., a touch node) for detecting a touch position can be formed at a point where a Tx line (or Tx lines) and an Rx line (or Rx lines) intersect.

[0307] For example, one node (e.g., a touch node) may be formed by one first metal mesh line (942) (e.g., local Tx lines) and one second metal mesh line (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines).

[0308] For example, a single node (e.g., a touch node) may be formed by a plurality of first metal mesh lines (942) (e.g., local Tx lines) and a plurality of second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines).

[0309] For example, a plurality of second switches (e.g., a plurality of Rx selection switches) may be selectively turned on or off to electrically connect or electrically insulate each of the second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made) from or to the touch fingerprint sensor IC (1240).

[0310] For example, the second Rx signal (e.g., the second Rx signal for fingerprint sensing) may be received from the second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at the touch location (1260) (e.g., the location where the touch is made). The second multiplexer (1230) (e.g., Rx multiplexer) may transfer (e.g., provide, transmit) the second Rx signal (e.g., the second Rx signal for fingerprint sensing) received from the second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at the touch location (1260) (e.g., the location where the touch is made) to the touch fingerprint sensor IC (1240).

[0311] According to one embodiment, the analog-to-digital converter (1244) of the touch fingerprint sensor IC (1240) may convert a second Rx signal (e.g., a second Rx signal for fingerprint sensing) received from second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made) into digital second touch values ​​(e.g., a touch value for fingerprint image generation).

[0312] For example, the touch controller (1242) of the touch fingerprint sensor IC (1240) can generate a fingerprint image based on second touch values ​​(e.g., touch values ​​for fingerprint image generation) of second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made).

[0313] For example, the touch controller (1242) of the touch fingerprint sensor IC (1240) can provide (e.g., transmit, transfer) second touch values ​​(e.g., touch values ​​for generating a fingerprint image) of second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at a touch location (1260) (e.g., a location where a touch is made) to the processor (1250). The processor (1250) can generate a fingerprint image based on the second touch values ​​(e.g., touch values ​​for generating a fingerprint image) of second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at a touch location (1260) (e.g., a location where a touch is made).

[0314] For example, while a second Tx signal (e.g., a second Tx signal for fingerprint sensing) is supplied to one first metal mesh line (942) (e.g., a local Tx line) (e.g., a local Tx touch fingerprint sensing line) disposed at a touch location (1260) (e.g., a location where a touch is made), a second Rx signal (e.g., a second Rx signal for fingerprint sensing) can be detected for all second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at the touch location (1260) (e.g., a location where a touch is made). The waveform scales of the first metal mesh lines (942) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) and the waveform scales of the second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) may be different.

[0315] An electronic device according to an embodiment of the present disclosure (e.g., the electronic device (1200) of FIG. 12) can perform fingerprint sensing using all first metal mesh lines (942) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) and all second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch is made). Through this, a fingerprint image can be generated with a resolution of about 500 dpi. When a fingerprint image is generated with a resolution of about 500 dpi, even the ridges of the fingerprint and the sweat pores on the surface of the finger can be imaged, thereby further enhancing security.

[0316] According to one embodiment of the present disclosure, the display (900) (e.g., a rollable display, a flexible display) of an electronic device (1200) can be slid in a first direction (e.g., direction ① of FIG. 2A) to expand the screen (e.g., a pull-out state of the rollable display).

[0317] According to one embodiment of the present disclosure, the display (900) (e.g., a rollable display, a flexible display) of the electronic device (1200) can be slid in a second direction (e.g., direction ② of FIG. 2A) so that the screen can be reduced (e.g., a retracted state of the rollable display).

[0318] An electronic device (1200) according to an embodiment of the present disclosure can determine, when a fingerprint sensing operation is performed, whether the display (900) (e.g., a rollable display, a flexible display) is in an expanded screen state (e.g., an extended screen state of the rollable display) or a contracted screen state (e.g., an extended screen state of the rollable display). For example, the processor (1250) can determine, using a sensor module (e.g., a sensor module (176) of FIG. 1), whether the display (900) (e.g., a rollable display, a flexible display) is in an expanded screen state (e.g., an extended screen state of the rollable display) or a contracted screen state (e.g., an extended screen state of the rollable display).

[0319] An electronic device (1200) according to an embodiment of the present disclosure can adjust a position at which a user interface for fingerprint sensing (e.g., a user interface for inducing fingerprint sensing) is displayed according to the expanded state (e.g., the pulled-out state) of the display (900) (e.g., a rollable display, a flexible display) when the display (900) (e.g., a rollable display, a flexible display) is in an expanded state (e.g., a pulled-out state of the rollable display).

[0320] FIG. 14 is a flowchart illustrating a method of operating an electronic device including a touch fingerprint integrated sensor according to an embodiment of the present disclosure.

[0321] Referring to FIG. 14, in operation 1410, an electronic device (e.g., electronic device (1200) of FIG. 12) can detect a touch event (e.g., whether a touch has occurred on a display (e.g., whether a touch has occurred on a display (900) of FIG. 12). For example, a processor (e.g., processor (1250) of FIG. 12) can detect a touch event (e.g., whether a touch has occurred on a display (900)).

[0322] In operation 1420, the electronic device (1200) can determine a touch location (e.g., a touch location (1260) of FIG. 12) (e.g., a location where a touch was made) based on touch values ​​of each of a plurality of Rx touch channels (e.g., a plurality of Rx touch channels (1214) of FIG. 12).

[0323] For example, the processor (1250) can determine a touch location (e.g., a touch location (1260) of FIG. 12) (e.g., a location where a touch was made) based on touch values ​​of each of a plurality of Rx touch channels (e.g., a plurality of Rx touch channels (1214) of FIG. 12).

[0324] For example, a touch fingerprint sensor IC (e.g., a touch fingerprint sensor IC (1240) of FIG. 12) can determine a touch location (e.g., a touch location (1260) of FIG. 12) (e.g., a location where a touch was made) based on touch values ​​of each of a plurality of Rx touch channels (e.g., a plurality of Rx touch channels (1214) of FIG. 12).

[0325] At operation 1430, the electronic device (1200) may determine whether fingerprint authentication is required. For example, the electronic device (1200) may determine whether fingerprint authentication is required based on the execution of an application requiring fingerprint authentication. For example, the processor (1250) may determine whether fingerprint authentication is required. For example, the processor (1250) may determine whether fingerprint authentication is required based on the execution of an application requiring fingerprint authentication.

[0326] If fingerprint authentication is not required as a result of the judgment of action 1430, the action can be terminated.

[0327] If fingerprint authentication is required as a result of the judgment of operation 1430, operation 1440 can be performed.

[0328] In operation 1440, the electronic device (1200) may supply a second Tx signal (e.g., a second Tx signal for fingerprint sensing) to first metal mesh lines (e.g., the first metal mesh lines (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected).

[0329] For example, the processor (1250) may operate the touch fingerprint sensor IC (1240) and the first multiplexer (1220) (e.g., a Tx multiplexer) to supply a second Tx signal (e.g., a second Tx signal for fingerprint sensing) to individual first metal mesh lines (e.g., the first metal mesh lines (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) arranged at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected). For example, a second Tx signal (e.g., a second Tx signal for fingerprint sensing) may be supplied to an individual first metal mesh line disposed at a touch location (1260) (e.g., a location where a touch occurred), and second Rx signals (e.g., a second Rx signal for fingerprint sensing) of all second metal mesh lines disposed at the touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected) may be detected. For example, the second Tx signal (e.g., a second Tx signal for fingerprint sensing) may be supplied sequentially to the last first metal mesh lines (e.g., the first metal mesh line (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines) disposed at the touch location (1260) (e.g., a location where a touch occurred). For example, whenever a second Tx signal (e.g., a second Tx signal for fingerprint sensing) is supplied to one first metal mesh line disposed at a touch location (1260) (e.g., a location where a touch occurred), the electronic device (1200) can detect an Rx signal (e.g., a background Rx signal) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines) disposed at the touch location (1260) (e.g., a location where a touch occurred).In operation 1450, the electronic device (1200) can detect a second Rx signal (e.g., a second Rx signal for fingerprint sensing) of second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected). For example, an Rx sensing value for fingerprint recognition can be obtained for the second metal mesh lines (944)) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) disposed at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected).

[0330] For example, the processor (1250) may operate the touch fingerprint sensor IC (1240) and the second multiplexer (1230) (e.g., Rx multiplexer) to obtain Rx sensing values ​​for fingerprint recognition for the second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) arranged at the touch location (1260) (e.g., the location where the touch occurred) (e.g., the location where the touch was detected).

[0331] In operation 1460, the electronic device (1200) may generate a fingerprint image based on second Rx sensing values ​​(e.g., Rx sensing values ​​for fingerprint recognition) detected from second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) positioned at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected).

[0332] For example, the processor (1250) may generate a fingerprint image based on second Rx sensing values ​​(e.g., Rx sensing values ​​for fingerprint recognition) detected from second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) positioned at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected).

[0333] For example, the touch fingerprint sensor IC (1240) can generate a fingerprint image based on a second Rx sensing value (e.g., an Rx sensing value for fingerprint recognition) detected from second metal mesh lines (944) (e.g., local Rx lines) (e.g., local Rx touch fingerprint sensing lines) positioned at a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected).

[0334] In operation 1470, the electronic device (1200) may perform fingerprint authentication by comparing the generated fingerprint image with a reference fingerprint image (e.g., a sample fingerprint image, a fingerprint image template) stored in a memory (e.g., the memory (130) of FIG. 1, the memory (130) of FIG. 12). For example, the reference fingerprint image (e.g., a sample fingerprint image, a fingerprint image template) may be stored in a separate secure memory. For example, the secure memory may be an area logically separated from the general memory, or may be a physically separated memory.

[0335] For example, the processor (1250) may perform fingerprint authentication by comparing the generated fingerprint image with a reference fingerprint image (e.g., a sample fingerprint image, a fingerprint image template) stored in a memory (e.g., the memory (130) of FIG. 1, the memory (130) of FIG. 12, the secure memory). For example, the operation of performing fingerprint authentication by comparing the currently generated fingerprint image with a reference fingerprint image stored in a secure memo may be performed by a separate security processor. For example, the fingerprint authentication operation may be performed in a secure environment. The secure environment in which fingerprint authentication is performed may be logically separated from the general execution environment, or may be physically separated. For example, the security processor is an example of a physically separated environment, and may include a logically separated example (TrustZone) and a physically separated example (eSE, Secure Processor). For example, the security processor may operate as a physically separate processor, and may perform the fingerprint authentication operation solely by the security processor. For example, the fingerprint authentication operation may be distributed and performed by the processor (1250) and the security processor.

[0336] An electronic device (1200) according to an embodiment of the present disclosure may perform a touch sensing operation and perform a fingerprint sensing operation on a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected) based on the touch sensing result. By performing fingerprint sensing on a touch location (1260) (e.g., a location where a touch occurred) (e.g., a location where a touch was detected), latency for fingerprint authentication may be reduced and power consumption may be reduced.

[0337] An electronic device (1200) according to one embodiment of the present disclosure can perform both touch sensing and fingerprint sensing, thereby performing fingerprint authentication by sensing a fingerprint directly at the location where a touch is made. Regardless of where a user touches the screen of the electronic device (1200), fingerprint authentication can be performed by sensing a fingerprint directly at the location where the touch is made.

[0338] An electronic device (1200) according to an embodiment of the present disclosure can perform touch sensing and fingerprint authentication simultaneously (e.g., substantially simultaneously) or in parallel, thereby enabling application login using fingerprint authentication. An electronic device (1200) according to an embodiment of the present disclosure can eliminate the inconvenience of having to perform a separate login when executing an application requiring fingerprint authentication.

[0339] According to one embodiment, the operations illustrated in FIG. 14 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIG. 2A, the electronic device (300) of FIG. 3A, and the electronic device (1200) of FIG. 12) loading instructions stored in a memory (e.g., the memory (130) of FIG. 1, and the memory (130) of FIG. 12). The operations illustrated in FIG. 14 may be performed by a processor (e.g., the processor (120) of FIG. 1, and the processor (1250) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 14 may be performed by a touch fingerprint sensor IC (e.g., the touch fingerprint sensor IC (453) of FIG. 4, and the touch fingerprint sensor IC (1240) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 14 may be performed by a display driver IC (e.g., a display driver IC (430) of FIG. 4) loading instructions stored in a memory (130). For example, the operations illustrated in FIG. 14 may be performed sequentially, or at least some of the operations may be performed in parallel.

[0340] FIG. 15 is a drawing showing a change in a fingerprint recognition driving position according to expansion (or contraction) of a rollable display according to one embodiment of the present disclosure.

[0341] FIG. 16 is a flowchart illustrating a fingerprint authentication method according to expansion (or reduction) of a rollable display according to one embodiment of the present disclosure.

[0342] Referring to FIG. 15, an electronic device according to an embodiment of the present disclosure (e.g., electronic device (1200) of FIG. 12) can determine, when performing a fingerprint sensing operation, whether a display (1500) (e.g., display (900) of FIGS. 10 and 11) (e.g., rollable display, flexible display) is in an expanded screen state (e.g., a pulled-out state of a rollable display) or a reduced screen state (e.g., a pulled-in state of a rollable display).

[0343] An electronic device (1200) according to an embodiment of the present disclosure can adjust a position at which a user interface for fingerprint sensing (e.g., a user interface for inducing fingerprint sensing) is displayed according to the expanded state (e.g., the pulled-out state) of the display (900, 1500) (e.g., a rollable display, a flexible display) when the display (900, 1500) (e.g., a rollable display, a flexible display) is in an expanded state (e.g., a pulled-out state of the rollable display).

[0344] According to one embodiment, when fingerprint authentication is required during use of an electronic device (1200), it may be convenient to sense the user's fingerprint at a fixed location (e.g., the bottom of the display (900, 1500)) regardless of screen expansion or reduction, and perform fingerprint authentication by generating a fingerprint image.

[0345] When the electronic device (1200) includes a flexible display (e.g., a rollable display), a user interface for fingerprint authentication may be displayed (1510) at a first location (①) in a reduced screen state. When the screen of the flexible display (e.g., a rollable display) is enlarged, the user interface (1510) moves to a second location (②) where it is displayed.

[0346] An electronic device (1200) according to one embodiment of the present disclosure can change the location where a user interface (1510) is displayed from a second location (②) to a first location (①) (1520) (e.g., move to the lower part (e.g., bottom) of the display) when the screen of a flexible display (e.g., rollable display) is enlarged.

[0347] For example, in the case of fingerprint recognition at the first position (①), the Tx lines (TX(x)) must be driven by the display expansion (Δy) so that they remain the same, but the Rx lines (RX(y)) must drive the Rx lines (RX(y-Δy)) at the position (y-Δy) moved downwards as much as the flexible display (e.g., rollable display) is expanded. The electronic device (1200) can change the Rx lines (RX(y)) driven according to the expansion of the flexible display (e.g., rollable display). Through this, fingerprint recognition can be consistently performed at the first position (①) from the user's perspective. The electronic device (1200) can change the Rx lines (RX(y)) driven as much as the flexible display (e.g., rollable display) is expanded, and can also change the position of an icon (e.g., a GUI (graphical user interface) icon) indicating the fingerprint recognition position. This allows the user to perform fingerprint authentication at a location that feels consistent.

[0348] Referring to FIG. 16, in operation 1610, the electronic device (1200) may receive a fingerprint authentication request. For example, a processor (e.g., processor (1250) of FIG. 12) may receive a fingerprint authentication request from an application when executing the application.

[0349] In operation 1620, the electronic device (1200) can check the state (e.g., expanded or collapsed) of the display (e.g., rollable display).

[0350] For example, the processor (1250) can use a sensor module (e.g., sensor module (176) of FIG. 1) to determine whether the display (900, 1500) (e.g., rollable display, flexible display) is in an expanded state (e.g., a pulled-out state of a rollable display) or a reduced state (e.g., a pulled-in state of a rollable display).

[0351] For example, when a display (e.g., a rollable display) expands (or contracts) in the y-axis direction (e.g., vertical direction), the processor (1250) can determine the state (e.g., expansion or contraction) of the display (e.g., rollable display) based on the change value (Δy value) of the y-axis of the display (900, 1500) (e.g., rollable display, flexible display).

[0352] For example, when a display (e.g., a rollable display) expands (or contracts) in the x-axis direction (e.g., horizontal direction), the processor (1250) can determine the state (e.g., expansion or contraction) of the display (e.g., rollable display) based on the change value (Δx value) of the x-axis of the display (900, 1500) (e.g., rollable display, flexible display).

[0353] In operation 1630, the processor (1250) may display a fingerprint user interface (e.g., a user interface for fingerprint recognition) at a position where a change value (Δy value) in the y-axis (or a change value (Δx value) in the x-axis) is subtracted from a basic position value of the display (900, 1500) (e.g., a rollable display, a flexible display).

[0354] In operation 1640, the processor (1250) can individually drive the Tx lines (e.g., the first metal mesh lines (942)) and the Rx lines (e.g., the second metal mesh lines (944)) of the display (900, 1500) (e.g., the rollable display, the flexible display) at a position where the change value (Δy value) in the y-axis (or the change value (Δx value) in the x-axis) is subtracted from the basic position value.

[0355] In operation 1650, Rx sensing values ​​for fingerprint recognition can be obtained from Rx lines (e.g., second metal mesh lines (944)). The processor (1250) can generate a fingerprint image based on the obtained Rx sensing values ​​for fingerprint recognition. The processor (1250) can perform fingerprint authentication by comparing the generated fingerprint image with a reference fingerprint image (e.g., a sample fingerprint image, a fingerprint image template) stored in a memory (e.g., the memory (130) of FIG. 1, the memory (130) of FIG. 12).

[0356] According to one embodiment, the operations illustrated in FIG. 16 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIG. 2A, the electronic device (300) of FIG. 3A, and the electronic device (1200) of FIG. 12) loading instructions stored in a memory (e.g., the memory (130) of FIG. 1, and the memory (130) of FIG. 12). The operations illustrated in FIG. 16 may be performed by a processor (e.g., the processor (120) of FIG. 1, and the processor (1250) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 16 may be performed by a touch fingerprint sensor IC (e.g., the touch fingerprint sensor IC (453) of FIG. 4, and the touch fingerprint sensor IC (1240) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 16 may be performed by a display driver IC (e.g., a display driver IC (430) of FIG. 4) loading instructions stored in a memory (130). For example, the operations illustrated in FIG. 16 may be performed sequentially, or at least some of the operations may be performed in parallel.

[0357] FIG. 17 is a flowchart illustrating a method for storing and updating a background noise value of a touch fingerprint integrated sensor according to one embodiment of the present disclosure.

[0358] Referring to FIG. 17, in operation 1710, an electronic device (e.g., the electronic device (1200) of FIG. 12) may receive an update trigger of a background noise from a touch fingerprint sensor (e.g., the touch fingerprint sensor (940) of FIGS. 10 and 11) (e.g., a touch fingerprint integrated sensor). For example, a timer may be operated to determine whether a touch event occurs during a preset time or not. If a touch event does not occur during the preset time, an update trigger of the background noise may be generated. For example, a processor (e.g., the processor (1250) of FIG. 12) may receive an update trigger of the background noise.

[0359] In operation 1720, the electronic device (1200) may determine whether a touch event has occurred (e.g., a touch has occurred on the display (e.g., the display (900) of FIG. 12). For example, the processor (120) may determine whether a touch has occurred on the display (900).

[0360] In operation 1730, if no touch event occurs, the electronic device (1200) may supply a Tx signal (e.g., a background Tx signal) to all of the first metal mesh lines (e.g., the first metal mesh lines (942) of FIGS. 10 and 11) (e.g., Tx lines).

[0361] For example, when no touch event occurs, the processor (1250) may operate the first multiplexer (e.g., the first multiplexer (1220) of FIG. 12) (e.g., the Tx multiplexer) and the touch fingerprint sensor IC (e.g., the touch fingerprint sensor IC (1240) of FIG. 12) to supply a Tx signal (e.g., a background Tx signal) to all of the individual first metal mesh lines (e.g., the first metal mesh lines (942) of FIGS. 10 and 11) (e.g., the Tx lines).

[0362] For example, the electronic device (1200) can supply a Tx signal (e.g., a background Tx signal) to individual first metal mesh lines (e.g., the first metal mesh line (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines). The electronic device (1200) can detect an Rx signal (e.g., a background Rx signal) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines). At operation 1740, the electronic device (1200) can supply a Tx signal (e.g., a background Tx signal) to the last first metal mesh lines (e.g., the first metal mesh line (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines). The electronic device (1200) can detect an Rx signal (e.g., a background Tx signal) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines) whenever a Tx signal (e.g., a background Tx signal) is supplied to one of the first metal mesh lines (e.g., the first metal mesh line (942) of FIGS. 10 and 11) (e.g., local Tx lines) (e.g., local Tx touch fingerprint sensing lines).

[0363] For example, the processor (1250) may operate a second multiplexer (e.g., the second multiplexer (1230) of FIG. 12) (e.g., an Rx multiplexer) and a touch fingerprint sensor IC (e.g., the touch fingerprint sensor IC (1240) of FIG. 12) to detect (e.g., acquire, receive) an Rx signal (e.g., a background Rx signal) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines).

[0364] In operation 1750, the electronic device (1200) can generate a background noise value of the entire (e.g., the entire screen) of the flexible display (e.g., the rollable display) based on an Rx signal (e.g., a background Rx signal) detected (e.g., acquired, received) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines).

[0365] For example, the processor (1250) can generate a background noise value of the entire flexible display (e.g., the entire screen) based on an Rx signal (e.g., a background Rx signal) detected (e.g., acquired, received) from all of the second metal mesh lines (e.g., the second metal mesh lines (944) of FIGS. 10 and 11) (e.g., Rx lines).

[0366] In operation 1760, the electronic device (1200) can store the background noise value of the entire (e.g., the entire screen) of the generated flexible display (e.g., the rollable display) in a memory (e.g., the memory (130) of FIG. 1, the memory (130) of FIG. 12) and update the background noise value.

[0367] According to one embodiment, the operations illustrated in FIG. 17 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (200) of FIG. 2A, the electronic device (300) of FIG. 3A, and the electronic device (1200) of FIG. 12) loading instructions stored in a memory (e.g., the memory (130) of FIG. 1, and the memory (130) of FIG. 12). The operations illustrated in FIG. 17 may be performed by a processor (e.g., the processor (120) of FIG. 1, and the processor (1250) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 17 may be performed by a touch fingerprint sensor IC (e.g., the touch fingerprint sensor IC (453) of FIG. 4, and the touch fingerprint sensor IC (1240) of FIG. 12) loading instructions stored in the memory (130). The operations illustrated in FIG. 17 may be performed by a display driver IC (e.g., a display driver IC (430) of FIG. 4) loading instructions stored in a memory (130). For example, the operations illustrated in FIG. 17 may be performed sequentially, or at least some of the operations may be performed in parallel.

[0372] For example, the processor (1250) can obtain a fingerprint image value (e.g., fingerprint image data) of a touch location (1260) (e.g., a location where a touch is detected).

[0373] In operation 1830, the electronic device (1200) can obtain a background noise value (e.g., a local background noise value) of a touch location (1260) (e.g., a location where a touch is detected) from among background noise values ​​of an entire area (e.g., an entire screen) of a flexible display (e.g., a rollable display).

[0374] For example, the processor (1250) can obtain a background noise value (e.g., a local background noise value) of a touch location (1260) (e.g., a location where a touch is detected) from among background noise values ​​of the entire area (e.g., the entire screen) of a flexible display (e.g., a rollable display).

[0375] In operation 1840, the electronic device (1200) may subtract a background noise value (e.g., a local background noise value) of a touch location (1260) (e.g., a location where a touch is detected) from an acquired fingerprint image value (e.g., fingerprint image data).
