Abstract: Disclosed is a single flexible member that electrically connects a display panel and a touch panel to an external circuit. The flexible member comprises: a first connecting portion located at a first surface of the flexible member, having a display pad connecting unit configured to connect with a displaying element in the display panel, and a touch pad connecting unit configured to connect with a touch sensing element in the touch panel; a second connecting portion located at a second surface of the flexible member opposite to the first connecting portion, having a single connector configured to connect with the external circuit to control at least one of the displaying element and the touch sensing element; and a touch integrated circuit on the second surface of the flexible member, wherein the touch integrated circuit transmit a driving signal to the touch sensing element.

Abstract: A display device comprises a display panel configured to display an image. A fingerprint sensor is under the display panel and is configured to sense a fingerprint. An impact mitigating layer partially surrounds the fingerprint sensor and is configured to absorb impacts or pressure to the display device. A shielding layer is between the display panel and the fingerprint sensor and the impact mitigating layer. The shielding layer blocks at least one of heat, electromagnetic interference, or light.

Abstract: Provided is a display device that includes a display panel defined with an active area displaying an image and an inactive area outside the active area, the display panel including a substrate having a first surface and a second surface opposite the first surface; a plurality of pixels on the first surface of the substrate in the active area, each pixel including a pixel drive circuit; a transparent conductive layer on the second surface of the substrate covering the active area and a part of the inactive area; and a metal pattern on the second surface of the substrate in the inactive area, the metal pattern electrically connected to the transparent conductive layer, receiving an electrical signal and having a lower resistance than the transparent conductive layer, wherein the metal pattern serves as a conductive path to reduce a potential difference with respect to the electrical signal in an entire area of the transparent conductive layer compared to a display device without the metal pattern.
