Drawings
Fig. 1 is a flowchart of an e-book display method according to an embodiment of the present invention.
Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, fig. 1 shows a method for quickly displaying an electronic paper book screen based on Android, where the electronic paper book screen is driven by an Android architecture, any commercially available liquid crystal electronic paper book is selected from the electronic paper book screen, and due to a large screen refresh interval of the electronic paper book, in order to increase a screen display speed, the method includes the following steps, S100 obtains a book opening instruction of a user, S101 selects a text file in a storage module according to the book opening instruction of the user, and S102 also reads contents to be displayed other than display contents corresponding to a current page in the text file in advance when displaying the display contents corresponding to the current page;
s103, acquiring current display configuration information, calculating and configuring the read content to be displayed into a page to be displayed according to the current display configuration information, and synthesizing the page to be displayed, wherein the synthesis mainly refers to data format conversion and conversion into a data format required by an eink display interface. And S105, transmitting the page to be displayed to a screen for display through an eink interface. The configuration information includes page pixel size, font size, page margin, etc., and configures the content to be displayed into a page to be displayed according to the configuration information. The display contents of three pages before the current page, three pages after the current page and the tenth page before and after the current page can be configured in advance. And when the system needs to call different pages, sending the rendered page to be displayed to the eink interface for displaying.
Further, the method also comprises the step that S104 receives a user page changing instruction, and the corresponding page to be displayed is transmitted to a screen for display through an eink interface according to the user page changing instruction S105. The user page changing instruction can be collected through the touch screen module, and the user page changing instruction can be 'previous page', 'next page', 'previous 10 pages', 'next 10 pages', and the like. When the system receives a 'previous page' instruction, sending the previous page in the rendered pages to be displayed to a screen through an eink interface for displaying; and when a next page command is received, sending the next page in the rendered pages to be displayed to a screen through an eink interface for displaying, when a previous 10 pages command is received, sending the previous 10 th page in the rendered pages to be displayed to the screen through the eink interface for displaying, and when a next 10 pages command is received, sending the next 10 th page in the rendered pages to be displayed to the screen through the eink interface for displaying. The design scheme can also make the response more rapid after receiving the user instruction.
In other specific embodiments, the synthesizing of the page to be displayed includes synthesizing the content to be displayed into the page to be displayed through a surfefinger function. Or the page to be displayed is firstly converted through the Surfacefinger format, then is converted through the HWC data format, and then is transmitted to the screen for display through the eink interface. HWC (hwcomposer) is a HAL Layer module for window (Layer) synthesis and display in Android, used for color to black and white color window conversion in e-book, which may have no HWC data format conversion step when the default color matching of e-book does not need to be black and white.
The scheme also introduces an Android-based electronic paper book screen fast display storage medium, which stores a computer program, wherein the electronic paper book screen is driven by an Android architecture, and the computer program is executed when being operated, and comprises the following steps of obtaining a book opening instruction of a user, selecting a text file in a storage module according to the book opening instruction of the user, and reading contents to be displayed except for display contents corresponding to a current page in the text file in advance when displaying the display contents corresponding to the current page;
and acquiring current display configuration information, calculating and configuring the read content to be displayed into a page to be displayed according to the current display configuration information, synthesizing the page to be displayed, and transmitting the page to be displayed to a screen for display through an eink interface.
In a further embodiment, the computer program further executes the following steps when executed, and the steps include receiving a user page changing instruction, and transmitting a corresponding page to be displayed to a screen for display through an eink interface according to the user page changing instruction.
In other specific embodiments, the synthesizing of the page to be displayed includes synthesizing the content to be displayed into the page to be displayed through a surfefinger function.
In some further embodiments, the computer program when executed further performs the steps of converting the HWC data format of the page to be displayed and transmitting the converted page to the screen for display via the eink interface. It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
