Problems solved by technology

In an environment with limited embedded hardware devices, when a browser parses a webpage, it draws pictures in the video memory, which is generally not large, so if there are many pictures in the webpage, especially if the network situation is not When it is very good, each picture is displayed after it is drawn, and it is very easy to display flickering phenomenon. When browsing your favorite EPG (Electronic Program Guide) webpage content, the frequent flickering will make people visually unacceptable, and if the display terminal size of the user's own home is relatively large, the display flickering problem will be even more serious

Embodiment

[0017] This example provides a method to reduce the display flicker of the embedded browser. First, the memory is used as the virtual video memory. After all the pictures to be displayed are drawn and filled in the memory, the memory is used as a "big" bit The picture can be drawn and displayed by the underlying drawing API. Because sometimes the network environment is relatively poor, it is not possible to wait until all the pictures are downloaded and filled into the memory before displaying. Therefore, combined with the original architecture of the browser display module, add The concept of the threshold value, most of the pictures that can be downloaded to the local within the threshold value are first filled and displayed in the memory, and the rest are handed over to the I / O module and the display module to continue downloading in the background, and then directly handed over to the graphics library The underlying API displays a separate video memory, and its system flow ...

Abstract

The invention relates to the computer technique, which solves the weakness of display flicker of embedded browsers and provides a method for reducing display flicker of embedded browsers. The technical scheme comprises that the method for reducing flicker display of embedded browsers is characterized by including the following steps: a, pre-defining a display region in the memory according to thesize of a display terminal, b, designing and drawing the memory drawing function at the memory region via combining interface parameters of API of the bottom layer of graphic library of a browser, and corresponding to the drawing API function of the bottom layer to draw a picture part in the memory region, c, completing drawing the picture part, converting the picture in the memory region from internal memory to video memory by the drawing API of the graphic library and then displaying, d, displaying a word part, and performing output display directly via the interface function of the graphiclibrary. The method has the advantages of high displaying efficiency with sound effect and little flicker, which is adaptable to embedded browsers.

Description

technical field [0001] The present invention relates to computer technology, in particular to embedded browser technology. Background technique [0002] As we all know, in the embedded device environment, limited by hardware conditions, the browser dominates almost everything and becomes the only application software interacting with the user, while the embedded browser and the general desktop browser have no special functions. The most important difference is nothing more than the organization and establishment of the DOM (Document Object Model) tree, the typesetting engine and the display engine. Among them, the most direct and profound user experience should be the part of the display engine. Display efficiency will be directly related to the quality evaluation of the entire browser. In an environment with limited embedded hardware devices, when a browser parses a webpage, it draws pictures in the video memory, which is generally not large, so if there are many pictures ...
