Abstract: A display device may include a first touch sensing member on a top surface of a display panel, a second touch sensing member on a bottom surface of the display panel, a main FPCB coupled to the display panel and including first and second connecting portions, a first touch FPCB connected to the first touch sensing member and the first connecting portion, a second touch FPCB connected to the second touch sensing member and the second connecting portion, a first touch driving circuit on the first touch FPCB, and a second touch driving circuit on the second touch FPCB. The first touch driving circuit and the first connecting portion may be positioned opposite to each other with respect to the main FPCB. The second touch driving circuit and the second connecting portion may be positioned opposite to each other with respect to the main FPCB.

Abstract: A display device includes a display panel configured to receive a first-frame image signal for displaying a first-frame image in a first frame. The display panel is further configured to receive a second-frame image signal for displaying a second-frame image in a second frame that immediately follows the first frame such that the display panel appears to display a transition region associated with a boundary between a portion of the first-frame image and a portion of the second-frame image and moving in a moving direction. The display device further includes an optical effect layer and electrode sets. The electrode sets respectively overlap different portions of the optical effect layer and are configured for sequentially starting affecting the different portions of the optical effect layer such that the optical effect layer appears to display a light-blocking section that moves in the moving direction and overlaps the transition region.
