Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] An embodiment of the present invention provides a screen method, including:

[0033] Unified refresh method, such as figure 1 As shown, the above unified refresh method includes:

[0034] Step 101: Store the first drawing information generated by the timer-based drawing in the screen buffer, and store the second drawing information generated by at least one event-based drawing in the above-mentioned in the screen buffer;

[0035] Since the timer-based drawing is a periodic drawing process, the screen w...

Abstract

The invention discloses a method and device for refreshing a screen, and relates to the technical field of screen displaying. The work efficiency in the screen refreshing process can be improved. The method for refreshing the screen includes a uniform refreshing method. The uniform refreshing method includes the steps that first drawing information generated through drawing based on a timer is stored in a buffering area of the screen, and before drawing based on the timer is completed, second drawing information generated through at least one time of drawing based on an event is stored in the buffering area of the screen; after drawing based on the timer is completed, the screen is refreshed based on the first drawing information and the second drawing information in the buffering area of the screen. The method and device are mainly applied to the refreshing process of images on the screen.

Description

technical field [0001] The invention relates to the technical field of screen display, in particular to a screen refreshing method and device thereof. Background technique [0002] During the process of displaying images on the screens of devices such as computers and tablet PCs, it is necessary to draw on the screens. Usually the display engine supports two different drawing methods: one is event-based drawing; the other is timer-based drawing. Event-based drawing refers to drawing triggered in response to events, such as drawing in response to user operations to create a new window, and timer-based drawing refers to periodic drawing in response to timers, such as video images during video playback of drawing. Event-based drawing is an invalid area redraw mechanism. When an application or system needs to redraw an area on the screen, it needs to set this area as an invalid area. The system generates a redraw event for the invalid area, and the application responds to this...
