Abstract
A touch control device is provided and includes a base substrate and a metal pattern on the base substrate. The metal pattern includes a first metal pattern and a second metal pattern. The first metal pattern and the second metal pattern are in different layers. The first metal pattern includes a first touch control electrode and a first virtual graphic that is insulated from the first touch control electrode. The second metal pattern includes a second touch control electrode and a second virtual graphic that is insulated from the second touch control electrode. An orthographic projection of the metal pattern to the base substrate is a regular grid.
