Embodiment Construction

[0040] The inventor has done in-depth research on the electronic paper book reader in the prior art, and found that its inherent display mechanism is the main reason for the flickering phenomenon of the screen, so a targeted display method for the Eink screen is proposed, It can be widely used in Eink screen-based devices.

[0041] For ease of understanding, the following firstly introduces the display mechanism of a typical Eink screen in the prior art and analyzes the cause of the screen flickering problem. figure 1 A flow chart showing the display mechanism of a typical electronic paper book reader in the prior art when turning pages, the display mechanism includes the following steps:

[0042] Step 101: Open the book in View mode.

[0043] Step 102: The screen receives a user's instruction to trigger page turning.

[0044] Step 103: The operating system reads the text content of the next page.

[0045] Step 104: call the system function invalidate () to start the automa...

Abstract

The invention provides a display method used for an electronic ink screen. A page is displayed by using a view of a GLSurfaceView type. The display method comprises the following steps of 1) identifying an operation instruction of triggering change of the page, and obtaining contents of a next page to be displayed; 2) obtaining a control right of the current view; 3) drawing a white color on a drawing board of the current view and then projecting the current view to the screen; 4) drawing the contents of the next page to be displayed into a page image data file corresponding to the current view; 5) filling the drawing board of the current view with the page image data file obtained in the step 4); and 6) rendering the current view onto the screen. According to the method, handwritings displayed on the Eink screen are clear without residual images; the flicker phenomenon of the Eink screen is avoided, so that the user experience is improved; and the response speed of the Eink screen is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular, the invention relates to a display method for an electronic paper ink screen. Background technique [0002] Electronic paper ink (Eink, also known as electronic ink) is a new material technology that combines chemistry, physics and electronics. At present, Eink technology has been widely used in electronic paper book readers, display cards, dual Screen mobile phones and other fields. Eink screens are usually referred to as electronic paper in the industry. The reflectivity of electronic paper is higher than that of commonly used reflective LCDs and closer to the level of newspapers, so it has an eye-protecting effect compared to traditional LCD displays. At the same time, e-paper has the ability to save data, and only consumes power when the screen is updated, and the information can still be retained on the monitor after the power is turned off, so e-paper also has the advantage...
