Title:
CONDUCTIVE MIDDLE FRAME AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/138367
Kind Code:
A1
Abstract:
Embodiments of the present application provide a conductive middle frame and a preparation method therefor, and a display device. The conductive middle frame comprises a plastic base body and a conductive material distributed in the plastic base body; the conductive material comprises a carbon fiber and a carbon nanotube; the mass of the carbon fiber accounts for 2%-12% of the mass of the plastic base body; the mass of the carbon nanotube accounts for 2%-8% of the mass of the plastic base body. The conductive middle frame has good conductivity, and can enable a display device to meet high-specification ESD and RE performance requirements; moreover, the conductive middle frame has good appearance characteristics, is not prone to fiber exposure, and has excellent mechanical properties such as high toughness.
