Abstract: Provided is an electronic device measuring user's biometric information. The electronic device includes a display module including a display panel, in which a signal transmission region, a peripheral display region adjacent to the signal transmission region, and a main display region spaced apart from the signal transmission region are provided, and a camera module overlapped with the signal transmission region. The display panel includes a plurality of first pixels, which are disposed in a unit region of the main display region, and a plurality of second pixels, which are disposed in a unit region of the peripheral display region. An emission area of green light in the unit region of the first pixels is different from an emission area of green light in the unit region of the second pixels.

Abstract: A display device includes a substrate, a driving layer which is disposed on the substrate, and includes first driving circuit groups each including N first pixel driving circuits and photo pixels each including a photo driving circuit and a photo sensor electrically connected to the photo driving circuit. A display element layer is on the driving layer, and includes first display element groups each including N first display elements electrically connected to the respective N first pixel driving circuits. Minimum distances between first color display elements included in the first display elements in a first predetermined direction in a plan view, are substantially the same. A distance between two first pixel driving circuits adjacent to each other in a second predetermined direction with the photo pixel therebetween in the plan view is different from a distance between two first pixel driving circuits continuously disposed in the second predetermined direction.

Abstract: A display device includes a screen having a plurality of pixels displaying an image. A projector includes a light source emitting a first light and a light converter configured to change an intensity of the first light with respect to each of the plurality of pixels so that the projector emits a conversion light. Each of the plurality of pixels of the screen includes a light receiving element configured to receive the conversion light and to generate a current proportional to an intensity of the conversion light. A light emitting element is configured to display the image based on the generated current.
