Patent ID: 11592931

Abstract:
A display panel includes common electrodes in an active area and a first driving circuit on one side of the active area and a second driving circuit on the other side of the active area. First read-out lines are electrically connected to the common electrodes, respectively, and to the first driving circuit. Second read-out lines are electrically connected to the second driving circuit, and to the first read-out lines, respectively. An output signal of phototransistors may be detected using read-out lines connected to a common electrode serving as a touch sensor, such that touch sensing and photosensing can be performed using the shared read-out line. No disconnection areas are provided between the read-out lines driven by the different driving circuits, or the disconnection areas are distributed. Abnormalities in image quality due to the disconnection areas are prevented, and a sensing function using the shared read-out lines is provided.
