The invention relates to a capacitance-type touch screen assembly. The capacitance-type touch screen assembly comprises a touch screen body, a control module, a connecting module, a cover plate which is used for fixing the touch screen body and an external module which is arranged above the touch screen body, wherein one end of the control module is electrically connected with the touch screen body, the other end is electrically connected with the connecting module, the connecting module is also electrically connected with a display device, the touch screen body comprises a panel layer, an adhesion layer and a film layer, which are sequentially laminated together, the film layer is provided with a metal grid which is formed by distributing metal conductive materials, and the capacitance-type touch screen assembly is externally arranged on a display screen panel in an adhesion manner or in a mechanical clamping manner. Compared with the prior art, the capacitance-type touch screen is externally arranged on the display screen, so that the capacitance-type touch screen assembly is firm, stable, simple in structure, plug-and-play through in a wire connection manner or a wireless connection manner, convenient and rapid, and the low-cost ordinary display device can be upgraded to the touch functional display screen.
