Description
Technical field
The present invention relates to electronic ink screen, particularly relate to electronic ink screen ghost sweep-out method, display packing and corresponding electronic equipment.
Background technology
Electronic ink technologies (ElectronicPaperDisplay, English abbreviation EPD) is made by the new technique that environment light shows. The charged particle of dichromatism black, white is packaged in microcapsule structure by EPD Display Technique system, the lifting moving of different electric charge black and white granule (ink droplet) is controlled by extra electric field, to present the display effect of monochrome, under the effect of electric field, the ink droplet that black and white is two kinds different is not stopped transport dynamic, and when the ink droplet of white rises to upper surface, all of ambient lighting is mapped to upper surface and is completely reflected, material is thus formed the state of white, the namely state of paper. When, after exchange electrode, the ink droplet meeting switch of two kinds of colors, so the ink droplet of white just can go to following, and the ink droplet of black is arrived above, and light is all absorbed by the ink droplet of black, and result results in black, is also the formation of white and black displays. It addition, can also there be the state of mixing at upper surface, the mixing that ink droplet two kinds different is proportional, so can form black and white and have the different colours of gray-level.
Owing to EPD technology can present the white and black displays effect of high reflectance, high contrast, having memory effect, after extra electric field is cancelled, the display that instant playback is currently presented, such as the content as shown in same printed paper simultaneously. Owing to having bistability, after power electrical field is cancelled, remain in and image is retained some months or several years by EPD display screen. This technology because reflective display can be realized by environment light, the typographical display effect of similar plain paper.
The displaying principle feature of EPD technology itself determine its easily stay when image refreshing updates ghost (former frame or number frame picture vestige). Current EPD product is basically used for e-book series products, they are when processing ghost, main method is: adopt once many GTGs completely to refresh mode (the GC16 refresh mode of such as industry), drive all ink droplets corresponding in each pixel to carry out once complete motion, and then the vestige of a upper picture is removed clean. Fig. 1 schematically shows once many GTGs and completely refreshes mode.
As it is shown in figure 1, in each pixel, a large amount of ink droplets (Fig. 1 only illustrates an ink droplet 20, for instance, black ink droplet, exemplarily) all completely refresh mode according to once many GTGs and move. Namely, under electric field action, the first the top 11 moving to microcapsule from present position 13 of ink droplet 20, then the bottom 12 of microcapsule is moved to from the top 11 of microcapsule, move to once the final position 14 when many GTGs have completely refreshed from the bottom 12 of microcapsule more afterwards. In once many GTG completely refreshing modes, all ink droplets are required for again resetting once, then move to the position of correspondence, and refresh time is longer, needs the time of about 700ms under the 65Hz refreshing frequency of screen. Once many GTGs completely refresh and can effectively eliminate electronic ink screen ghost, but the shortcoming that this refreshing mode is brought is that refresh time is long, and the flickering thus caused is serious, even in e-book product, still receives denouncing of a large number of users.
Except once many GTG completely refreshing modes, the refreshing mode removing ghost of prior art also includes completely refreshing mode without GTG: it is that ink droplet is all in reset position (the top of microcapsule or bottom that this kind refreshes the premise of mode, screen shows completely black or entirely white), ink droplet is under the driving of voltage afterwards, all moving toward another reset position, this refreshing takes around 260ms and can complete. Fig. 2 schematically shows the mode that completely refreshes without GTG.
As in figure 2 it is shown, in each pixel, a large amount of ink droplets (Fig. 2 only illustrates an ink droplet 20, for instance, black ink droplet, exemplarily) all move according to completely refreshing mode without GTG. That is, under electric field action, ink droplet 20 moves to another reset position (bottom 12 of microcapsule) from being currently located reset position (the top 11 of microcapsule). Although the ghost elimination effect completely refreshing mode without GTG is better, but, need first all to be resetted by ink droplet owing to implementing this refreshing mode, it is achieved get up not very convenient. And, the refresh rate of 260ms is still fast not, and human eye easily experiences screen flickering.
In order to further improve refresh rate, completely refresh on mode basis in prior art without GTG, propose without GTG imperfect refreshing mode (namely so-called A2 refresh mode): this kind of refreshing mode is on upper a kind of basis refreshing mode, for speed-optimization. By the time that artificial limitation refreshes, it is limited in about about 80ms. Now, ink droplet, under black and white state, carries out incomplete motion, i.e. ink droplet is not fully moved to extreme position (reset position). This refreshing mode sub-screen display speed is very fast, it is shown that a frame picture only needs such as 80ms, and namely one second electronic ink screen can refresh 12.5 frames. Fig. 3 schematically shows without the imperfect refreshing mode of GTG.
As it is shown on figure 3, in each pixel, a large amount of ink droplets (Fig. 3 only illustrates an ink droplet 20, for instance, black ink droplet, exemplarily) all move according to without the imperfect refreshing mode of GTG. That is, under electric field action, within the time of about 80ms, ink droplet 20 moves to the position being positioned at below microcapsule from the present position being positioned at above microcapsule. Further, since refresh time only has about 80ms, ink droplet 20 will not move to extreme position (reset position).
Although without the imperfect refreshing mode of GTG on refresh rate quickly, but, in visual effect, the picture contrast after refreshing without GTG imperfect refreshing mode is adopted completely to refresh mode not as employing once many GTGs and completely refresh the picture contrast after mode refreshes without GTG.
In existing EPD technology, after the refresh rate of electronic ink screen, ghost elimination effect, refreshing, the aspect such as distortion degree and screen flicker sense is difficult to coordinate.
