Abstract: The present application provides a conductive laminated structure and a method for manufacturing the same, and a touch-control display device, wherein, an opening is formed in a conductive layer after the conductive layer is formed on a substrate, so that more of the metal nanowires in a metal nanowire conductive layer can be exposed out of the surface of an adhesion enhancement layer and get in contact with a signal connection layer; furthermore, at least part of the signal connection layer is embedded into the opening along the thickness extending direction, thus ensuring the adhesiveness while enlarging the lap-jointed area of the signal connection layer with the metal nanowire conductive layer, which in turn reduces impedance and increases conductivity, and thereby further reduces response time; thus ensuring the conductivity while reducing the overall area percentage of the bezel area, so as to meet the design requirement for a narrow bezel.

Abstract: A display device, a display panel thereof, and an OLED array substrate. The OLED array substrate includes a display area, and the display area includes a non-transparent display area and a transparent display area. The non-transparent display area is provided with first OLED sub-pixels arranged in an array, and the transparent display area is provided with second OLED sub-pixels in one row and several columns. When the columns of second OLED sub-pixels are driven, the transparent display area performs a display function; when the columns of second OLED sub-pixels are not driven, the transparent display area performs a light transmitting function.
