Abstract
The invention belongs to the technical field of surface decoration and particularly relates to a backlight plastic panel with a capacitive touch drive. The backlight plastic panel comprises a key panel casing. The panel is characterized in that a light-transmission key indication area of the capacitive touch drive is arranged on the surface of the key panel casing and located on the surface of a thin film printed with transparent conductive ink and connected with a conductive circuit. The backlight plastic panel has the advantage that the panel is a plastic panel product adopting the capacitive touch drive and has the backlight function. In the area requiring backlight design, the transparent conductive ink is matched with a conductive circuit structure, the plastic and the thin film are integrally molded into the panel in an in-mould injection molding mode, micro current is transferred through the key indication area on the surface of the touch plastic panel to drive the electronic function to light a light source under the panel in driving mode, so that the panel has the backlight function. Conductive contacts are arranged in a plastic layer to prevent the plastic layer from reducing sensitivity of the capacitive touch drive.
