Description

Electronic ink screen ghost sweep-out method, display methods and corresponding electronic equipment

Technical field

The present invention relates to electronic ink screen more particularly to electronic ink screen ghost sweep-out methods, display methods and phase The electronic equipment answered.

Background technique

Electronic ink technologies (Electronic Paper Display, English abbreviation EPD) are shown by environment light New technology.The charged particle of black, white dichromatism is packaged in microcapsule structure by EPD display technology system, not by extra electric field control With the lifting moving of charge black and white particle (ink droplet), to show the display effect of monochrome, under the action of electric field, black and white Two different ink droplets are kept moving, and when the ink droplet of white rises to upper surface, all ambient lightings are mapped to upper surface quilt Fully reflective, material is thus formed the states of white, that is, the state of paper.After exchanging electrode, the ink droplet meeting of two kinds of colors Position is exchanged, white ink droplet in this way can be gone to following, and the ink droplet of black is arrived above, and light is whole by the ink droplet of black It absorbs, as a result results in black, be also formed white and black displays.In addition, can also have the state of mixing in upper surface, two kinds are not The proportional mixing of same ink droplet, can form black and white in this way and have the different colours of gray-level.

Since EPD technology can show the white and black displays effect of high reflectance, high comparison, while there is memory effect, works as handle After extra electric field is cancelled, the currently presented display of instant playback, such as the content as shown in same printed paper.Due to tool There is bistability, after power electrical field cancellation, image is retained into some months or several years still on EPD display screen.The skill Art by environment light because can realize reflective display, the typographical display effect of similar plain paper.

The displaying principle feature of EPD technology itself determines that it is easy to leave ghost (before i.e. when image refreshing updates The trace of one frame or number frame picture).Current EPD product is basically used for e-book class product, they are main when handling ghost Wanting method is: completely refreshing mode (such as GC16 refresh mode of industry) using primary more grayscale, drives in each pixel Corresponding all ink droplets carry out primary complete movement, and then the removing of the trace of a upper picture is clean.Fig. 1 schematically shows Go out primary more grayscale and completely refreshes mode.

As shown in Figure 1, in each pixel, a large amount of ink droplets (ink droplet 20 is only shown in Fig. 1, for example, black ink droplet, As example) completely refresh mode according to primary more grayscale and moves.That is, under electric field action, ink droplet 20 is first from being currently located Position 13 moves to the top 11 of microcapsules, then the bottom 12 of microcapsules is moved to from the top of microcapsules 11, later Primary more grayscale, which are moved to, from the bottom of microcapsules 12 again completely refreshes the final position 14 when completing.It is complete in primary more grayscale In whole refreshing mode, all ink droplets require to reset again once, then move to corresponding position, and refresh time is longer, is shielding The time of about 700ms is needed under the 65Hz refreshing frequency of curtain.Primary more grayscale, which completely refresh, can effectively eliminate electric ink Screen ghost, but the refreshing mode bring the disadvantage is that, refresh time is too long, thus caused by flickering it is serious, even In e-book product, denouncing for a large number of users is still received.

Other than primary more grayscale completely refreshing mode, the refreshing mode of the removing ghost of the prior art further includes ashless Rank completely refreshes mode: the premise of such refreshing mode is that ink droplet is all in the reset position (the top of microcapsules or most Lower section, screen show completely black or complete white), ink droplet is all moved toward another reset position under the driving of voltage later, this Refreshing, which takes around 260ms, to be completed.Fig. 2 schematically shows no grayscale completely to refresh mode.

As shown in Fig. 2, in each pixel, a large amount of ink droplets (ink droplet 20 is only shown in Fig. 2, for example, black ink droplet, As example) completely refresh mode according to no grayscale and moves.That is, under electric field action, ink droplet 20 resets position from being currently located It sets (the tops 11 of microcapsules) and moves to another reset position (bottoms 12 of microcapsules).Although the complete side of refreshing of no grayscale The ghost elimination effect of formula is preferable, still, needs first all to reset ink droplet due to implementing the refreshing mode, implement not It is very convenient.Moreover, the refresh rate of 260ms is still not fast enough, human eye, which easily experiences screen, flickering.

In order to further improve refresh rate, on the basis of the prior art is without grayscale completely refreshing mode, propose The no imperfect refreshing mode of grayscale (namely so-called A2 refresh mode): such refreshing mode is in a kind of upper base of refreshing mode On plinth, for speed-optimization.The time refreshed by artificial limitation, it is limited in about 80ms or so.At this point, ink droplet is in black and white Under state, incomplete movement is carried out, that is, ink droplet is not fully moved to extreme position (reset position).This refreshing mode Sub-screen shows that speed is very fast, shows that a frame picture only needs such as 80ms, i.e. one second electronic ink screen can refresh 12.5 frames.Fig. 3 schematically shows the imperfect refreshing mode of no grayscale.

As shown in figure 3, in each pixel, a large amount of ink droplets (ink droplet 20 is only shown in Fig. 3, for example, black ink droplet, As example) moved according to the imperfect refreshing mode of no grayscale.That is, under electric field action, within the time of 80ms or so, ink Drop 20 moves to the position below microcapsules from the present position being located above microcapsules.In addition, when due to refreshing Between only 80ms or so, ink droplet 20 will not move to extreme position (reset position).

Although without the imperfect refreshing mode of grayscale on refresh rate quickly, in visual effect, using no grayscale Picture contrast after imperfect refreshing mode refreshes is not so good as completely to be refreshed mode using primary more grayscale and completely brushed without grayscale Picture contrast after new paragon refreshing.

Above several method for refreshing, can effectively eliminate ghost, but can all generate certain flickering.

Therefore the refreshing opportunity of electronic ink screen is just particularly important, and the refreshing mode of Current electronic book is by opportunity classification There are two types of: screen-refresh all removes ghost using complete refresh each time, or specified by carrying out again after page turning several times manually Refresh.
