A naked-eye three-dimensional display method constructed on two half-screens, a naked-eye three-dimensional display device, and a terminal equipment are provided in embodiments of the disclosure, the two half-screens being configured to display respectively images corresponding to a left eye and a right eye of an observer respectively, the method comprising: detecting in a real-time manner distances between both ends of each row of pixels on each of the half-screens and a corresponding eye of the observer through which said each of the half-screens is viewed; calculating light-exiting angles formed from displayed pixels on said each of the half-screens to the corresponding eye through which said each of the half-screens is viewed, as a function of a length of each of the half-screens and the distances between both ends of each row of pixels on each of the half-screens and the corresponding eye through which said each of the half-screens is viewed; and controlling light rays outputted from the displayed pixels to the corresponding eye through which said each of the half-screens is viewed, with a collimated light adjusting device, according to the light-exiting angles formed from the displayed pixels on said each of the half-screens to the corresponding eye through which said each of the half-screens is viewed, so as to focus displayed contents on said each of the half-screens onto the corresponding eye through which said each of the half-screens is viewed.
