The embodiments of the present disclosure provide a GOA circuit of an array substrate and a display apparatus, which are used in the field of display technology, and enable reducing short-cut of a GOA unit due to ESD, and improving the yield of the GOA circuit. Such an arrangement may reduce a number of components and simplify the fabrication process. The core functionality provided by the application may be preserved between the client and the server wherein improved network performance may provided along with improved offline service capabilities. The clip includes a positioning portion abutting against the heat sink, and two retaining arms extending from opposite ends of the positioning portion.
