Embodiment Construction

[0029] Such as figure 1 As shown, a method for updating content displayed on a screen includes the following steps:

[0030] Step S10, when an event of updating the displayed content on the screen is detected, the displayed content before updating and the displayed content after updating are acquired. The event to update the content displayed on the screen can be generated by the user moving the page by pressing keys, touching the screen or scrolling the mouse wheel. Move one or more lines down, or switch the entire page; the event of updating the screen display content can also be the change of the selected object, the selected object refers to the highlighted content in the screen content, such as the highlighted content selected by the user in the web page For pictures or texts, etc., such as selected highlighted files in the resource manager, the user can switch the selected object by pressing a button or touching the screen, thereby generating an event to update the cont...

Abstract

The invention discloses a method for updating screen display contents. The method comprises the following steps of: acquiring non-updated display contents and updated display contents when a screen display content updating event is detected; and judging whether same parts exist between the updated display contents and the non-updated display contents, if so, copying the non-updated display contents, drawing changed display contents, combining the copied non-updated display contents and the drawn changed display contents and display, otherwise, drawing the updated display contents and displaying. Moreover, the invention further relates to a system for updating screen display contents. In the method for updating screen display contents, the presence of same parts is judged by comparing the updated display contents with the non-updated display contents, if so, the same parts are copied, the changed contents are drawn, and the same parts are not required to be drawn, so that the updating drawing efficiency of the screen display contents is increased greatly.

Description

【Technical field】 [0001] The invention relates to electronic information technology, in particular to a method and system for updating screen display content. 【Background technique】 [0002] Usually, on some software running platforms, such as the J2me platform for mobile phone software, when updating the content displayed on the screen, it only needs to call a function to redraw on the screen to realize the content updating. However, when there are many objects to be drawn, or when it is more complicated, the drawing of the previous screen has not been finished, and the next drawing is called again, causing the screen to flicker, and in severe cases, the screen will tear, that is The upper half of the screen and the lower half of the screen do not display the same content. The traditional double-buffering technology is used. When drawing, the object is first drawn to the buffer A, which is a picture with the same size as the screen, and then the picture is pasted on the sc...
