Embodiment Construction

[0024] figure 1 It is an embodiment of the E-ink electronic paper screen display method of the present invention, and the specific implementation method is as follows:

[0025] First of all, it is necessary to determine whether there is new content that needs to be displayed on the E-ink electronic paper screen. This can be done by periodically scanning the memory that caches the content to be displayed, so as to know that there is new content to be displayed; or the result that there is new content to be displayed can be obtained when the user turns pages and other commands are issued. If there is no new content to be displayed, no processing is necessary. If it is judged that there is new content to be displayed, the next step is processed.

[0026] The second step is to judge whether any pixel has changed. This step is performed after it is determined that there is new content to be displayed. The main purpose of this step is to judge whether the gray scale of pixels ch...

Abstract

In order to solve the problem of frequent flashing when an E-ink electronic paper screen is used in the prior art, the invention provides a display method of the E-ink electronic paper screen, which comprises the steps of: when new content needs to be displayed in the E-ink electronic paper screen, comparing the content displayed in the current E-ink electronic paper screen with the new content; if the change of pixels occurs, computing a minimum rectangle containing all changed pixels in the E-ink electronic paper screen; if the number of the changed pixels is greater than the number of the preset pixels and the area of the minimum rectangle is greater than the area of the preset rectangle, carrying out the globally refreshing process in the range of the E-ink electronic paper screen; and otherwise, carrying out the locally refreshing process. The invention can effectively solve the problem of flashing of the E-ink electronic paper screen.

Description

technical field [0001] The invention relates to a method for displaying an electronic screen, in particular to a method for refreshing the screen when the content displayed on the electronic screen changes. Background technique [0002] Electronic paper is a new type of electronic display that has emerged in recent years. It has almost the same visual perception as paper documents, and it will not cause visual fatigue for a long time. At the same time, it has the usual advantages of electronic displays, that is, continuous conversion and refresh display The content, together with the auxiliary storage device, can carry a large amount of text content in a small volume, which is convenient for readers to carry with them. [0003] As a popular name, electronic paper actually includes a variety of implementation technologies, mainly including electronic ink, cholesteric liquid crystal display technology, electrophoretic display technology (EPD) and electrowetting display technol...
