    Abstract: An electronic device according to one embodiment of the present invention can comprise a display panel, a display controller, a memory, and a processor electrically connected to the display panel, the display controller, and the memory. The memory can store instructions, when executed, which allow the process to: draw an image in response to a periodic synchronization signal; compose the drawl image in response to the synchronization signal after the drawing of the image; transmit the composed image to the display controller in response to synchronization signal after the composing of the image; measure, after the transmitting of the composed image, a first standby time until the next synchronization signal is generated; perform control such that the display panel displays an image in response to the generation of the next synchronization signal; determine a first offset value on the basis of the first standby time; and determine an image composition time point by applying the first offset value to the periodic synchronization Additionally, various examples are possible.

    Abstract: An example electronic device may include a display including a main display area and at least one expansion display area expandable from the main display area; and a processor operatively coupled to the display. The processor is configured to, while the electronic device is in a slide-in state, display, on the main display area, a first screen corresponding to an application executed in the slide-in state; based on a portion of the expansion display area being slid out, generate a second screen to be displayed on the main display area and a portion of the slid-out expansion display area; generate a slide effect screen and display the same on at least a portion of the slid-out expansion display area, at least at the same time as the generation of the second screen; and based on the generation of the second screen being completed, remove the display of the slide effect screen and display the second screen on the main display area and the slid-out expansion display area.

    Abstract: A sub-sampling phase locked loop includes a slope generating and sampling circuit, first and second transconductance circuits, a constant transconductance bias circuit, a loop filter and a voltage controlled oscillator. The slope generating and sampling circuit generates a sampling voltage based on a reference clock signal and an output clock signal. The first and second transconductance circuits generate first and second output control voltages based on the sampling voltage, a reference voltage and a control current. The constant transconductance bias circuit includes a switched capacitor resistor. The constant transconductance bias circuit is configured to generate the control current. The loop filter is connected to output terminals of the first and second transconductance circuits. The voltage controlled oscillator generates the output clock signal based on the first and second output control voltages.

    Abstract: An electronic device includes a display including a plurality of regions, a display driver integrated circuit configured to drive a first region of the display at a first driving frequency and drive a second region of the display at a second driving frequency according to a configuration of the display, and a processor configured to provide display data to the display driver integrated circuit. The processor identifies a driving frequency of a first screen to be output on the display in response to reception of a first input; and controls the display to output at least a portion of the first screen on a region, of the plurality of regions, driven at a driving frequency corresponding to the driving frequency of the first screen. The display optimizes driving frequency, thus reducing heating problems and resource waste in the electronic device.
