Abstract
A display apparatus and a display method for a multi-layer superimposition are provided. When a display presents a user interface, a touch trajectory from a user can be detected via a touch component, and a touch trajectory pattern is present in a first layer; upon obtaining the touch trajectory pattern, an interpolation operation can also be performed on the touch trajectory pattern in the first layer according to a background pattern in a second layer; finally, a converted pattern obtained after the interpolation operation and the background pattern are superimposed and presented on the display.
