description An electronic device according to various embodiments of the present disclosure, which can improve the image quality of a display by preventing color changes according to gradation, comprises: a display comprising a plurality of pixels including light emitting elements, and a pixel driving circuit for light emission of the light emitting elements; a display driver integrated circuit (DDI) driving the display; a processor operatively coupled to the DDI; and a memory operatively coupled to the processor. Each of the plurality of pixels comprises: a first pixel driver circuit block generating a pulse width modulation (PWM) signal for controlling a driving timing of the light emitting element; and a second pixel driver circuit block regulating the intensity of a current supplied to the light emitting element, wherein the first pixel driver circuit block comprises a plurality of transistors and a first capacitor, and the second pixel driver circuit block comprises a plurality of transistors and a second capacitor. 본 개시의 다양한 실시 예에 따른 전자 장치는, 발광 소자를 포함하는 복수의 픽셀들 및 상기 발광 소자의 발광을 위한 픽셀 구동 회로를 포함하는 디스플레이; 상기 디스플레이를 구동하는 DDI(display driver integrated circuit); 및 상기 DDI와 작동적으로 연결된 프로세서; 상기 프로세서와 작동적으로 연결된 메모리;를 포함하고, 상기 복수의 픽셀들 각각은, 상기 발광 소자의 구동 타이밍을 제어하기 위한 PWM(pulse width modulation) 신호를 생성하는 제1 픽셀 구동 회로 블록 및 상기 발광 소자에 공급되는 전류의 세기를 조절하는 제2 픽셀 구동 회로 블록을 포함하고, 상기 제1 픽셀 구동 회로 블록은 복수의 트랜지스터들 및 제1 커패시터를 포함하고, 상기 제2 픽셀 구동 회로 블록은 복수의 트랜지스터들 및 제2 커패시터를 포함할 수 있다.
