Electronic device with a backlight and capacitive touch panel and method for controlling electronic device so as to suppress error detection of a touch operation
Abstract:
Provided an electronic device capable of suppressing the effects of noise caused by driving of a backlight, and preventing an erroneous detection of an operation on a touch panel. The electronic device includes a display, a touch panel, which is arranged on a display surface side of the display and is capable of detecting a touch operation, a backlight of the display, a backlight control unit configured to drive and control a current of the backlight based on pulse width modulation, and a CPU. The CPU is configured to cause the backlight control unit to drive and control the backlight at a current drive frequency different from a sub-scanning frequency of the touch panel.
