Description

Scanning method for touch sensing of displays in electronic devices and electronic devices

[0001] Various embodiments of the present disclosure relate to scanning for touch sensing of a display in an electronic device.

[0002] Recently, input devices such as touch input devices (e.g., touchscreens) or pen input devices (e.g., digitizers) have been widely used for user interfaces in electronic devices.

[0003] A touchscreen can provide touch input signals by detecting touch. Touch detection methods include resistive, capacitive, infrared, ultrasonic, and / or camera methods. Capacitive methods can be widely applied to portable electronic devices such as smartphones and tablet PCs.

[0004] The digitizer can provide pen input signals by an electronic pen or stylus pen, and the pen recognition methods include pressure-sensitive, capacitive, passive, active, and electromagnetic resonance or induction (EMR) methods.

[0005] In an electronic device, touch input actions and pen input actions can be performed independently. The electronic device can scan the entire area of ​​the touchscreen to detect touch, and when the scan detects a touch (e.g., a touch by a palm), the electronic device can perform a pen input recognition action using the pen input device.

[0006] When an electronic device simultaneously performs touch input based on touch detection and pen input based on pen recognition, some touch inputs may be unnecessary inputs detected as incidental to pen input. For example, when an electronic device places a palm on a touchscreen and writes or draws with a pen, the electronic device may scan the entire touchscreen even though some areas that are not related to pen input do not require scanning, resulting in unnecessary power consumption.

[0007] According to one embodiment, when writing or drawing with a pen while placing a palm on an electronic device, a partial scan is performed by identifying a scan area and a scan exclusion area among the entire area of ​​a touchscreen and performing a scan only on the scan area, instead of a full scan, thereby reducing power consumption, and a scanning method for touch sensing of a display in the electronic device can be provided.

[0008] According to an embodiment, an electronic device may include a display including a touch sensor circuit and a pen input circuit, a memory storing instructions, and a processor. The instructions according to an embodiment, when executed by the processor, may cause the electronic device to identify a first palm position on the display through the touch sensor circuit and to identify a hover-in state by a pen device through the pen input circuit. The instructions according to an embodiment, when executed by the processor, may cause the electronic device to identify a first position of the pen device, first tilt information of the pen device, and a first screen state of the display based on the identification of the first palm position and the hover-in state. In one embodiment, the instructions, when executed by the processor, may cause the electronic device to identify a first scan area in which scanning is to be performed by the touch sensor circuit and a first scan exclusion area in which scanning is not to be performed by the touch sensor circuit based on the first palm position, the first position of the pen device, the first tilt information, and the first screen state. In one embodiment, the instructions, when executed by the processor, may cause the electronic device to control the touch sensor circuit to perform a first partial scan such that scanning is performed on the first scan area and not scanning the first scan exclusion area.

[0009] In one embodiment, a scanning method for touch sensing of a display in an electronic device may include an operation of identifying a first palm position on the display through a touch sensor circuit and identifying a hover-in state by a pen device through the pen input circuit. In one embodiment, the method may include an operation of identifying a first position of the pen device, first tilt information of the pen device, and a first screen state of the display based on the identification of the first palm position and the hover-in state. In one embodiment, the method may include an operation of identifying a first scan area and a first scan exclusion area among scan areas by the touch sensor circuit based on the first palm position, the first position of the pen device, the first tilt information, and the first screen state. In one embodiment, the method may include an operation of performing a scan on the first scan area through the touch sensor circuit and performing a first partial scan that does not perform a scan on the first scan exclusion area.

[0010] According to one embodiment, a non-transitory storage medium storing commands is provided, wherein the commands, when executed by an electronic device, are configured to cause the electronic device to perform at least one operation, wherein the at least one operation may include an operation of identifying a first palm position on the display through a touch sensor circuit and identifying a hover-in state by a pen device through a pen input circuit. According to one embodiment, the at least one operation may include an operation of identifying a first position of the pen device, first tilt information of the pen device, and a first screen state of the display based on the identification of the first palm position and the hover-in state. According to one embodiment, the at least one operation may include an operation of identifying a first scan area and a first scan exclusion area among scan areas by the touch sensor circuit based on the first palm position, the first position of the pen device, the first tilt information, and the first screen state. In one embodiment, the at least one operation may include performing a scan on the first scan area through the touch sensor circuit and performing a first partial scan that does not perform a scan on the first scan exclusion area.

[0011] According to embodiments of the present disclosure, when writing or drawing with a pen while placing a palm on an electronic device, power consumption can be reduced by performing a partial scan that identifies a scan area and a scan exclusion area among the entire area of ​​the touchscreen and performs a scan only on the scan area instead of a full scan.
