Abstract
An embedded touch control display device is disclosed. The embedded touch control display device includes a first substrate and a second substrate which are set oppositely; an in-plane switching (IPS) or fringe field switching (FFS) display mode display structure and a capacitance touch structure which are set between the first substrate and the second substrate, and the IPS or FFS display mode display structure is located on the first substrate and comprises a pixel electrode layer, a first medium layer, a public electrode layer and a crystal layer, and the capacitance touch structure is located on the second substrate and comprises touch electrode and a second medium layer; an planarization layer which is located between the second medium layer and the crystal layer; the distance between the touch electrode and the crystal layer is 4 micrometers to 7 micrometers.
