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: An electronic device includes a host controller. The host controller splits a to-be-displayed image into at least two sub images, where each sub image and an adjacent sub image thereof include at least one column of overlapping image pixels. The host controller sends the at least two sub images to at least two display drive circuits, so that the at least two display drive circuits can jointly drive a display screen to display the to-be-displayed image in a sub pixel rendering (SPR) manner.

Abstract: This application provides an electronic device, to reduce a probability that a screen stalling phenomenon. A timing control unit sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an Nth frame of display data within a preset time. The processing unit receives the Nth frame of display data in the (N+1)th frame, and controls, based on the Nth frame of display data, the display to display an Nth frame of image.

Abstract: A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.

Abstract: An ambient sound processing method provided includes determining a time-frequency spectrum of an ambient sound in preset duration. A matching scenario is determined from at least one preset scenario according to the time-frequency spectrum of the ambient sound in the preset duration, where a time-frequency spectrum of the matching scenario matches the time-frequency spectrum of the ambient sound in the preset duration. Operation information corresponding to the matching scenario is determined as the operation information to be executed, and an operation is performed according to the operation information to be executed and a subsequently received ambient sound, and an operated signal is determined. The operated signal is mixed to obtain a mixed signal, and the mixed signal is transmitted to a headset, where the mixed signal includes at least an audio signal played by user equipment of a user.
