Problems solved by technology

The advantage of global refresh is that it can make the background color of the refreshed page more pure, but the problem is that every time the page is turned, the screen will be black, causing an impact on the user's vision
In this dual mode, afterimages are reduced, but cannot be completely eliminated, and the most serious moment of afterimages is when the page is turned for the 19th time; in addition, compared with a single global refresh mode, the appearance of a black screen is also It has been greatly reduced, but every 20 times when the page is turned, there is still a black screen due to a global refresh
In other words, this dual mode of global refresh and partial refresh still cannot effectively eliminate afterimages and black screens

Embodiment Construction

[0023] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] In order to effectively eliminate the phenomenon of black screen and afterimage and improve the reading quality, the embodiment of the present invention adopts the method of dividing the electronic ink panel into several pixel sets for sequential refreshing, so that the process of turning pages is displayed in the form of animation, eliminating flash black and residual image. film.

[0025] figure 1 It is an effect display diagram of the electronic paper refreshing method in the embodiment of the present invention. As shown in the figure, when the electronic ink panel receives a new image of the next page, the electronic ink panel is divided into N pixel sets, respectively P 1 ,P 2 ,...,P n ,...,P N , where, n=0, 1, 2, ..., N, N≥2; P n All pixels that need to be refreshed in will be refreshed synchronously...

Abstract

The invention relates to page turning refreshing method and device for electronic paper. The method comprises the steps of receiving an image of a next page; dividing the page into N pixel sets which are P1, P2...Pn...PN respectively according to a page turning mode, wherein n=0, 1, 2...N, and N>=2; refreshing all pixels in the Pn synchronously; setting page turning starting moments and voltage sequences required by page turning of the pixels in the pixel sets for each pixel set, wherein the voltage sequences comprise a reset voltage sequence and a voltage sequence for refreshing the image of the next page; integrating the voltage sequences of the pixels in the pixel sets according to the starting moments of the pixel sets; and performing drive display according to the voltage sequences of the integrated pixels.

Description

technical field [0001] The invention relates to electronic paper, in particular to a method and device for flipping and refreshing electronic paper pages. Background technique [0002] E-paper display is a brand-new display, which has the advantages of ultra-thin, portable, rewritable, comfortable reading, low power consumption, and can maintain display even when power is off. As a new display technology, e-paper displays have spawned many innovative mobile applications, such as e-books, e-newspapers, and electronic display boards. [0003] Currently, unlike LCD screens and most other digital screens, e-paper screens don't require backlighting, making them closer to traditional forms of paper-and-ink reading. The current most popular electronic paper uses E-Ink's electrophoretic technology, which forms images through the movement of charged black and white particles suspended in a transparent liquid. The most important thing in the design and operation of e-books is the pa...
