Abstract
As in a touch control display device of the present invention, when second electrodes are formed, the second electrodes are connected in series respectively in the horizontal row direction and in the vertical column direction, so as to form a cross network with rows and columns insulated from one another, namely to form a touch control sensing layer. By integrating a touch control function into organic light-emitting diodes, a compact structure of the device is achieved, there is no need to set up a separate touch control component, the light emitting efficiency is high, and the respond speed is fast. As in a preparation method of the touch control display device of the present invention, second electrodes are formed into such a structure that the second electrodes are connected in series respectively in the horizontal row direction and in the vertical column direction, therefore, when organic light-emitting diodes are prepared, a touch control function can be integrated therein at the same time by means of technically mature photo-etching and etching techniques, which is a simple preparation method with low process cost.
