More Information
Summary:A display device includes a first area and a second area adjacent to the first area. A light emitting element may be disposed on the first area, and a pixel circuit connected to the light emitting element may be disposed on the second area. The first area includes a low transmittance area overlapping a cathode of a first pixel and a cathode of a second pixel and a high transmittance area which does not overlap the cathode of the first pixel and the cathode of the second pixel. Each of the cathode of the first pixel and the cathode of the second pixel receives a power voltage having a constant level during a first period and receives a driving signal during a second period. The present invention provides the display device having improved transmittance of a sensing area. 표시장치는 제1 영역 및 상기 제1 영역에 인접한 제2 영역을 포함한다. 제1 영역에 발광소자가 배치되고, 제2 영역에 발광소자에 연결된 화소 회로가 배치될 수 있다. 제1 영역은 제1 화소의 캐소드와 제2 화소의 캐소드에 중첩하는 저투과율 영역 및 제1 화소의 캐소드와 제2 화소의 캐소드에 비-중첩하는 고투과율 영역을 포함한다. 제1 화소의 캐소드와 제2 화소의 캐소드는 제1 구간 동안에 일정한 레벨의 전원전압을 수신하고, 제2 구간 동안에 구동신호를 수신한다.
