US 2022/0037418 A1 · DISPLAY DEVICE AND MOBILE TERMINAL DEVICE INCLUDING THE SAME

Abstract

A display device and a mobile terminal device including the same are provided, wherein the display device includes a display panel including a display area in which a plurality of display pixels are disposed, and a sensing area in which a plurality of display pixels and a plurality of sensor pixels are disposed. The display pixels of the display area and the display pixels of the first sensing area emit light by receiving a data voltage of an input image in a display mode. The sensor pixels in the first sensing area generate an electric currents according to light reflected from a fingerprint in a fingerprint recognition mode. A resolution of the display pixel is lower than a resolution of the sensor pixel in the first sensing area.
