Fig. 4 shows an example of a method of the present invention for switching a document page displayed on an electronic reader, and is also an example of the workflow of the electronic reader of the present invention. As shown in FIG. 4, under the control of the main controller, the standby document in the storage module is indexed, and the obtained index is stored in the standby library in the storage module; the standby library includes an index table, and the index table records the The corresponding index value of the alternate document.

The alternate document is a document that is specified after the user switches the target document. When the user needs to read the document for some reason, for example, the user does not want others to see the content that he or she reads, the target document can be switched and displayed. Alternate document.

The alternate library contains an index table and a book table. In this embodiment, the index table includes three attributes: ID, index value, and path.

When the user selects a document in the storage module of the e-reader as an alternate document as needed, the document is selected in a directory of the storage module, such as an SD card, and the document is used as an alternate document and established by a shortcut menu. Index, add the corresponding record in the index table after the index is completed. In the corresponding record, the index value is the index value of the selected alternate document, and the path is the corresponding storage path of the document on the storage module.

In this embodiment, the e-reader is a Linux platform, and the index table is as shown in FIG. 5:

For example, select "Pride and Prejudice" in the "Foreign Masters" directory as the alternate document, and use the document as the alternate document and index it by the shortcut menu. The index value is the generated four-digit random number. The path is The document is in the corresponding storage path on the storage module, and the record is inserted into the index table.

The names of all the alternate documents in the alternate library can be displayed on the bistable display by querying the index table in the alternate library. These alternate documents are documents that the user thinks should be read at a particular moment and are defined by the user. When the user selects an alternate document by using a stylus or a button, the index value corresponding to the backup document in the index table is queried, so that the index corresponding to the standby document in the index table is selected. After the query is performed in the index table, the path of the file in the storage module is obtained, and after the standby document is parsed according to the path, the page is loaded to the display module according to the page number when the standby document was last opened, if the standby document is first time Open and load the first page of the alternate document to the display module. If the page content of the alternate document contains a picture, the display module constructs and renders the picture through the display chip, and stores the constructed and rendered content in the cache of the display module.

After the backup document is loaded, the user selects the storage module of the e-reader through the stylus or the button. The target document that the user is interested in. The target document is opened, the e-reader parses the target document, and the parsed content is loaded into the memory of the e-reader and displayed on the bi-stable display. As the user continually flips through the contents of the target document, the content parsed by the target document is continuously loaded from memory and displayed on the bistable display. When the user does not want others to see what they are reading for some reason, clicking or sliding the capacitive touch panel, the capacitive touch panel generates a first trigger signal. The interrupt mechanism is used to respond to the first trigger signal, and after receiving the first trigger signal, the control display module loads the alternate document page onto the bi-stable display for display, and displays the target document displayed on the Han steady display. The page displayed when the first trigger signal is triggered is loaded to the display module. If the page content of the target document contains a picture, the display module constructs and renders the picture through the display chip therein, and stores the constructed and rendered content in the display module. Display module.

In this embodiment, in the list of the alternate documents displayed on the bi-stable display, the user selects by the stylus

In the column of "Pride and Prejudice", query the index value of the alternate document 7864, and after querying, get the path of the alternate document ". \doc\foreign masterpiece \ arrogance and prejudice. pdf" , load the backup from the path The document is parsed by the PDF parser and loaded into the corresponding page of the display module according to the page number when the standby document was last opened. In this embodiment, the document is last opened as page 12. The user selects "Ming dynasty. pdf" as the target document of interest to the user through the capacitive touch panel. The document is parsed by the PDF parser, and the parsed content is loaded into the e-reader's memory and displayed on the bistable display. When someone next to the user passes, do not want others to see what they are reading, and click the capacitive touchpad to generate the first trigger signal. At this time, the target document "Those things in the Ming Dynasty" can be displayed on the e-reader. On page 230, call page 12 of Pride and Prejudice from the display module and display it on the bistable display. At the same time, the page content on page 230 of "Things of the Ming Dynasty" is loaded into the display module.

After the page content of the alternate document is displayed on the bistable display, when the user continuously flips the page to read the contents of the alternate document, the content parsed by the alternate document is continuously loaded from the storage module and displayed on the bistable display. When the user feels that others will not see the content they are reading, and can continue to read the target document, the user clicks or slides the capacitive touch panel to generate a second trigger signal, and the second trigger signal is sent to the main controller to respond with an interrupt mechanism. a second trigger signal, after the main controller receives the second trigger signal from the capacitive touch panel, the main controller controls the display module to load the stored target document page to display on the bi-stable display, and The alternate document page displayed on the steady-state display is loaded into the display module, and the loaded content is buffered by the display module's cache, which can greatly speed up the switching display and ensure fast switching to the desired document page. After the display is switched, the speed at which the document continues to be turned over is not too fast, and the parsed document can be read directly from the storage module. In this embodiment, when the user repeatedly reads the contents of "Pride and Prejudice", the content parsed by "Pride and Prejudice" is continuously loaded from the memory and displayed on the bistable display. When the user feels that others will not see what they are reading, they can continue to read the "Things of the Ming Dynasty", and generate a second trigger signal through the capacitive touch panel. At this time, the alternate document "Pride and Prejudice" is in the e-reader. Displayed on page 20. Call the contents of page 230 of the Ming Dynasty from the cache of the display module and display the content on the silent display. At the same time, load the page content on page 20 of Pride and Prejudice to the display module. When the user keeps flipping through the pages of the "Ming Dynasty Things", the bistable display constantly loads the contents of the "Ming Dynasty" from the memory for display. After the page content of the target document is displayed on the bistable display, when the user continuously flips the page to read the contents of the target document, the content parsed by the target document is continuously loaded from the memory and displayed on the bistable display, thus completing A round of switching display. When the user does not want others to see the content that he or she reads for some reason, the first trigger signal is generated by clicking on the capacitive touch panel to start the switching display of the next round until the reading process ends.
