Various embodiments of the present disclosure relate to an electronic device for changing attributes of a display, and an operation method in an electronic device. The electronic device may be configured to: acquire user information; set user period information for changing attributes of the display based on the acquired user information; acquire information associated with content being displayed on the display or has been determined to be displayed on the display; change an attribute setting value of the display based on set user period information and the information associated with the content; and control the display to display content based on the changed attribute setting value.

Electronic device for changing attributes of display and operation method in electronic device

An electronic device is provided. The electronic device includes a display including an output area divided into a plurality of blocks, a display driving integrated (DDI) circuit configured to drive the display. and a processor electrically connected to the DDI circuit, wherein the processor is configured to obtain information about a content area of the output area, the content area displaying the at least one piece of content, based on the obtained information, classify the plurality of blocks into first group blocks, second group blocks, and third group blocks, and in order to display the at least one piece of content on the display, control the DDI circuit.

Method for driving display at multiple driving frequencies and electronic device performing same

An instruction of an electronic device is provided. The instruction of the electronic device, when executed by a processor, causes a display panel to be operated using one of a first gamma set corresponding to a first operating frequency and a second gamma set corresponding to a second operating frequency, each of the first gamma set and the second gamma set comprises gamma voltage values for each luminance and gradation, the first gamma set and the second gamma set include the same gamma voltage value in a first gradation range of a first luminance so as to have the substantially same optical characteristic when the operating frequency changes, the first gamma set and the second gamma set include the same gamma voltage value in a second gradation range of a second luminance, and the first gradation range and the second gradation range are different from each other.

Display screen control method and electronic device supporting same

An electronic device that quickly updates a screen when receiving an input from a peripheral device is provided. The electronic device includes a display driver integrated circuit (DDIC) configured to output a tearing effect (TE) signal having a designated frequency, and a processor configured to control the peripheral device, a display, and the DDIC and to transmit image data to the DDIC in response to the TE signal, wherein the DDIC is configured to output the TE signal at a first frequency, receive an interrupt signal from the peripheral device while the TE signal is output at the first frequency, output the TE signal at a second frequency in response to the interrupt signal, the second frequency being greater than the first frequency, receive image data updated by the processor based on the TE signal output at the second frequency, and drive the display to display the received image data.

Electronic device configured to quickly update screen upon receiving input from peripheral device

Certain embodiments relate to an electronic device and a method for changing gamma values and may include determining a target gamma curve related to first image data to be displayed by a display panel, receiving a request for switching a scan rate of the display panel from a first frequency to a second frequency, determining a gamma offset and an offset margin in response to reception of the request, determining a limit gamma curve generated by applying the gamma offset and the offset margin to the first gamma curve, generating second image data by correcting the first image data, based on a difference value between the limit gamma curve and the target gamma curve to map the first image data to the target gamma curve, and driving the display panel, based on the second image data and the limit gamma curve. This document may further include various other embodiments.

Electronic device and method for changing gamma according to refresh rate

An electronic device is provided. The electronic device includes a display panel and a display driver integrated circuit configured to drive the display panel. The display driver integrated circuit is configured to determine a luminance value of the display panel if a request for a change from a current driving frequency of the display panel to a target driving frequency is received, and determine at least one intermediate driving frequency between the current driving frequency and the target driving frequency depending on the luminance value of the display panel.
