Abstract
This application provides a film-like heat dissipation member, a bendable display apparatus, and a terminal device. The film-like heat dissipation member includes a heat dissipation layer. Composition and a structure of the heat dissipation layer are designed, so that a cutting-plane length of the heat dissipation layer changes in a surface bending process, can be bent repeatedly, and can implement uniform temperatures on two sides of the bendable display apparatus and the terminal device, thereby improving heat dissipation capabilities of the bendable display apparatus and the terminal device.
