According to one embodiment, when the processor 490 detects an approach to one side of the protective cover 403 by the sensor 450, the processor 490 uses the display driving IC 420 to reduce the frequency of the driving signal supplied to the display panel 410. ) can be controlled.

Since the driving signal supplied to the display panel 410 is supplied to the top of the display panel 410, relatively large noise may be generated at the top and bottom of the display panel 410. For example, the processor 490 may control the touch IC 440 to detect a touch only in the central portion of the touch panel 430, which is an area where noise is relatively low. For example, when the vertical coordinates of the touch panel 430 are 0 to 2560, the processor 490 may control the touch IC 440 so that touches are not detected at coordinates 0 to 800 and 2080 to 2560.

In Figure 5, it is shown that there is no temporal gap between the start time and end time of the section P1 and section P2 and the scan signals 515 and 525, but this is limited.

In operation 660, the electronic device may reduce the area where the touch input of the touch panel is detected. For example, an electronic device can only detect a touch input in the central area of the touch panel, which is an area where the amount of noise is relatively small. For another example, the electronic device may only detect a touch input in an area (e.g., 811 in FIG. 8) that corresponds to an area in which touch input is possible (e.g., area 830 in FIG. 8) of one side of the flip cover. there is.

The size of noise is smaller the closer the value is to 0. When setting the capacitance of the touch panel, the capacitance is set based on the central part of the touch panel, so the size of noise detected at the top and bottom of the touch panel may be relatively larger than the central part of the touch panel.

According to one embodiment, when the driving frequency is 60 Hz, noise of up to 50 or more can be detected in the touch panel. In this case, ghost touches may occur at the top and bottom of the touch panel.

According to one embodiment, when specified conditions are met (e.g., when a protective cover covers the front of the electronic device, when a high sensitivity mode is entered, or when the electronic device is charging, etc.), the electronic device adjusts the driving frequency to 60Hz. You can change it to 40Hz.

According to one embodiment, when the driving frequency is 40Hz, noise of up to 23 or less can be detected in the touch panel.
