Description

Display method and electronic equipment Technical Field The embodiment of the application relates to the technical field of display, in particular to a display method and electronic equipment. Background With continuous iteration of the electronic device, the requirement of the user on the human-computer interaction efficiency of the electronic device is higher. The fluency of the picture is one of important indexes for evaluating the man-machine interaction efficiency of the electronic equipment by a user. The smoothness of the picture of the electronic equipment is greatly influenced by the handedness of the electronic equipment. It will be appreciated that the chirality of an electronic device may be embodied as the length of delay time from "user input of an interactive operation to the electronic device" to "display of a graphical interface corresponding to the interactive operation by the electronic device". The longer the length of the delay time, the worse the chirality. Disclosure of Invention The embodiment of the application provides a display method and electronic equipment, which are used for improving the heel chirality of the electronic equipment when detecting the interactive operation made by a user. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a display method. The method is applied to the electronic equipment. The electronic device includes a buffer queue that may store rendering data for synthesizing image frames. The rendering data may be, for example, rendered frames drawn by an application running in the foreground in the electronic device. It will be appreciated that during the running of the application program foreground, an interactive operation of the user, such as the first operation, is detected, and the faster the image frame corresponding to the first operation is displayed, the better the following chirality of the electronic device is indicated. In some embodiments, the electronic device may generate the first discard information immediately after detecting the first operation. After the first discard information is generated, a determination may be triggered as to whether a number of frames of rendering data in the buffer queue is greater than or equal to a first number, the first number being a positive integer greater than 1. If the number of frames of the rendering data in the buffer queue is greater than or equal to the first number, determining that the buffer queue has a problem of frame stacking. Accordingly, at least two frames of rendering data are reduced in the buffer queue in response to the first vertical synchronization signal. The reduced at least two frames of rendering data include the first rendering data. The electronic device may synthesize a first image frame corresponding to the first rendering data, and display the first image frame. In addition, the application program running in the foreground can draw and render second rendering data corresponding to the first operation, and the second rendering data is stored in the cache queue. In this way, after the second vertical synchronization signal is generated, the second rendering data is fetched from the buffer queue, and the second image frame corresponding to the second rendering data is synthesized. The second vertical synchronization signal and the first vertical synchronization signal are both synchronization signals triggering processing of rendering data, and the second vertical synchronization signal is the next synchronization signal generated after the first vertical synchronization signal. Therefore, when the first vertical synchronization signal is received, the time length of waiting to be processed in the buffer queue of the second rendering data corresponding to the first operation is reduced by consuming at least two frames of rendering data at the same time, and further, the time length between receiving the first operation and displaying the second image frame is shortened. Therefore, in the scene of frame accumulation rendering, the decline of chirality is avoided, and the man-machine interaction efficiency of the electronic equipment is improved. In some embodiments, the fetched at least two frames of rendering data further comprise third rendering data. After fetching at least two frames of rendering data from the buffer queue, the third rendering data may be discarded in addition to the first image frame synthesizing the first rendering data. Optionally, the third rendering data is stored in the buffer queue earlier than the first rendering data. Optionally, the frame number of the third rendering data is arranged before the frame number of the first rendering data. It can be understood that each frame of rendering data corresponds to a frame number, and the arrangement sequence between the frame numbers can indicate the original display s
