摘要： An example electronic device includes a display panel configured to display a screen, a display driver IC (DDI) configured to supply a data voltage for displaying the screen to the display panel, and a processor configured to transmit image data for setting the data voltage to the DDI. The DDI is configured to generate a synchronization signal for controlling a time point at which the data voltage is supplied to the display panel, and to deliver the synchronization signal to the processor. The processor is configured to select a time point, at which the image data starts to be transmitted, within a waiting period of the synchronization signal.

摘要： On an electronic device which includes a display device comprising a display driving circuit, a processor, and a memory a method for changing a refresh rate of the display device includes: changing at least one of a first parameter, a second parameter, or a third parameter in response to identifying the occurrence of at least one of a scan rate change request or a change in scan rate change restriction, and applying the changed parameter among the first parameter, the second parameter, and the third parameter. The first parameter is the frequency of a first synchronization signal generated in the display driving circuit, the second parameter is the increase or decrease in a blank area to substitute for a portion of active video area in frame information, and the third parameter is the frequency of a second synchronization signal for rendering.

摘要： An electronic device configured to configure brightness of a display by using an illuminance sensor is provided. The electronic device includes acquiring a second front-surface sensing value smaller than a first front-surface sensing value through a first illuminance sensor while the brightness is a first brightness, comparing the second front-surface sensing value with a first rear-surface sensing value detected through a second illuminance sensor, determining, when the second front-surface sensing value is greater than the first rear-surface sensing value, whether a touch input is detected through a designated region of the display, maintaining the brightness at the first brightness when the touch input is detected, and when the touch input is not detected, adjusting the brightness of the display to a value lower than that of the first brightness, based on a first LUT stored in a memory, or maintaining the brightness of the display at the first brightness.
