Example Embodiment

The screen of the electronic book reader of the present invention adopts electrophoretic display technology for display. The screen (electronic paper) using this display technology does not need to be refreshed when the displayed content is not changed. Therefore, the so-called "refresh" refers to changing the content displayed on the screen of the e-book reader.

In traditional e-book readers, all areas of the screen need to be changed for each refresh, so the CPU of the e-book reader needs to calculate the potential distribution of the entire electrode layer of the screen and control the entire electrode layer of the screen Therefore, the display content of the screen is consistent with the potential distribution of the electrode layer.

In the present invention, only part of the screen area needs to be changed for each refresh, so that the CPU of the e-book reader only needs to calculate the potential of the electrode layer corresponding to the refresh area of ​​the screen, s...

Abstract

The invention discloses a method for refreshing an e-book reader, wherein the screen of the e-book reader is provided with an electrophoresis display technology, the operation of refreshing refers to the change of the content on the screen; the method provided by the invention is characterized in that the content on the screen is just partially refreshed at every refreshing time, the interval time between two refreshing operations is Delta t=d*a*Delta S/S; in the formula, d represents C1, or C2, or C3, or the c of the current books work, or the c of any books works; a represents the number of the words on the current page of the books work displayed by the e-book reader; Delta S represents the area of the screen of the e-book reader at every refreshing time, and the unit thereof is pixel; and S represents the total area of the screen of the e-book reader, and the unit thereof is pixel. The method for refreshing an e-book reader provided by the invention changes the fixed way of thinking of full screen refreshing of a conventional e-book reader, revolutionarily uses partial refreshing, or called as split screen refreshing, so that the refreshing time required in each time is shortened, and a continuous reading experience is provided for the users.

Description

technical field The invention relates to an electronic book reader, in particular to an electronic book reader using electrophoretic display technology (EPD). Background technique Electro-Phoretic Display (EPD) is a kind of electronic paper technology. Because its visual effect is closest to paper printing, it has become the mainstream of electronic paper technology at this stage. In 2009, more than 90% of the world's electronic paper uses electrophoretic display. technology. Microcapsule (Microcapsule) electrophoresis is a kind of electrophoretic display technology, represented by the American E-ink company. The microcapsule electrophoretic display technology particles are introduced below. The screen of an e-book reader using electrophoretic display technology consists of a substrate and a coating, where the substrate is usually glass, or metal or plastic; the coating includes a capsule layer and an electrode layer. The capsule layer is built with millions of microcaps...
