Abstract: A vertical synchronization signal-based control method. The method includes the electronic device draws a first layer of a first application in response to a first vertical synchronization signal, and buffers the first layer to a first buffer queue. The electronic device performs, in response to a second vertical synchronization signal, layer composition on the layer buffered in the first buffer queue, to obtain an image frame. The electronic device adjusts a signal period of the first vertical synchronization signal to first duration if a quantity of layers buffered in the first buffer queue is less than a first preset threshold, where the first duration is less than a signal period of the second vertical synchronization signal.

Abstract: Embodiments of this application provide a page drawing control method, apparatus, and device. The method includes: obtaining a drawing instruction for a first page, where the drawing instruction is used to instruct to draw the first page, the first page includes a first control, and the first control includes at least one child control; and if it is determined that an image corresponding to the first control exists and the first control and the child control in the first control are not updated, drawing the first control based on the image corresponding to the first control, or if it is determined that an image corresponding to the first control does not exist or the first control or the child control in the first control is updated, generating the image corresponding to the first control and drawing the first control. In this way, page drawing efficiency is improved.
