This application is a national stage application under 35 U.S.C. § 371 of International Application No. PCT/CN2020/122868, filed Oct. 22, 2020, the contents of which are incorporated by reference in the entirety.
The present invention relates to display technology, more particularly, to a display panel and a display apparatus.
In a chip-on-glass type and chip-on-film type display apparatuses, a flexible printed circuit is directly mounted on an edge of a display panel of the display apparatus. In addition, the connections between the flexible printed circuit and the display apparatus may be completely hidden inside the display apparatus, and isolated from the external environment. Typically, the flexible printed circuit in the display apparatus is mounted to the display substrate using an anisotropic conductive film. In the chip-on-glass type display apparatus, an integrated circuit is fabricated on a substrate of the display panel. In the chip-on-film type display apparatus, an integrated circuit is fabricated on the flexible printed circuit.
