Touch control display device and a preparation method thereof

Abstract

There is provided a touch control display device, wherein, second electrodes in the organic light-emitting diodes are connected in series in the same layer in a first direction so as to form a plurality of first conductive units (); the touch control layer comprises a plurality of second conductive units () arranged in parallel in a second direction, the first conductive units () and the second conductive units () are configured to be insulated from each other and to form a cross network. A touch control structure is formed by the cooperation of the first conductive units () consisting of the second electrodes and the second conductive units () in the touch control layer, thereby reducing the thickness of the touch control display device. Only the first encapsulation layer (), the touch control layer and the second encapsulation layer () are configured on the light-exiting surface of the organic light-emitting diodes, which not only has a compact structure but also effectively increases the light-emitting efficiency of the touch control display device. There is also provided a preparation method of the touch control display device, wherein, during the preparation process of the second electrodes, the second electrodes are formed into first conductive units () that cooperate with the second conductive units () in the touch control layer to constitute a touch control structure, which is a simple preparation method with low process cost.
