Description
Technical field
The present invention relates to a kind of E-book reader, particularly relate to the E-book reader of a kind of employing electrophoretic display technology (EPD).
Background technology
Electrophoretic display technology (Electro-Phoretic Display, EPD) be a kind of of electronic paper technology, because its visual effect near paper printing, therefore becomes the main flow of present stage electronic paper technology, the whole world 90% above Electronic Paper all adopted electrophoretic display technology in 2009.Microcapsules (Microcapsule) electrophoresis is a kind of of electrophoretic display technology, is representative with U.S. E-ink company.
Be introduced with microcapsules electrophoretic display technology particulate below.Adopt the screen of the E-book reader of electrophoretic display technology to be made up of substrate and plated film, wherein substrate is generally glass, also can be metal or plastics; Wherein plated film comprises capsule layer and electrode layer again.The capsule layer is a built-in microencapsulation up to a million in the silica gel sheet, is full of transparent lubricating fluid in each microencapsulation, wherein is suspended with countless nano level black and white particulates again.Black particle is electronegative, the white particles positively charged.Be subjected to the control of electrode layer current potential, float to the microencapsulation surface on black particle or the white particles.Display white during the white particles come-up shows black during the black particle come-up.The screen resolution of E-book reader is that size, the distribution density by the numerous microelectrode of electrode layer determined.Usually the volume of microencapsulation is greater than the volume of microelectrode, therefore may a part in microencapsulation be shown as white, a part is shown as black.The change in voltage of each microelectrode, black, white particulate come-up or sinking in the microencapsulation of driving correspondence.When black, white graininess need not change, without any need for voltage.Therefore, even the outage of the screen of E-book reader still can keep shown image, thereby also can avoid simultaneously refreshing at a high speed reaches purpose of saving.Black, a white particulate reflected light in the microencapsulation, not luminous, so the screen of E-book reader is reflective viewing screen, but not the such luminescent screen of CRT, LCD.
When the screen of above-mentioned E-book reader need refresh, promptly need from a kind of literal of demonstration or pattern transition during for another kind of literal that shows or pattern, be current potential by each microelectrode in the electrode layer of the CPU of E-book reader control screen, thus the light and shade of each pixel in the control screen.It all is full frame refreshing that present E-book reader refreshes at every turn, according to the processing speed of CPU, after needing usually to wait for for 1～5 second, could show new literal or pattern on the screen of E-book reader.In refresh process, the screen of E-book reader also can blackening once, thereby this is that full frame brush is black once owing to be to cause ghost because black, the white particulate in the microencapsulation may have faint dissipation when making alive not, promptly force to reset the primary particle state, can eliminate ghost.Obviously, the refresh time that E-book reader is very long, and the experience of screen blackening can cause the interruption of reading for the user, be easy to produce sense of fatigue.
Summary of the invention
Technical matters to be solved by this invention provides the method that a kind of E-book reader refreshes, and can improve the shortcoming that the full frame refresh time of existing E-book reader is long, user's reading experience is not good.
For solving the problems of the technologies described above, the method that E-book reader of the present invention refreshes, the screen of described E-book reader adopts electrophoretic display technology, describedly refresh that displaying contents changes on the screen that refers to E-book reader, it is characterized in that, only refresh at every turn subregion in the described screen is refreshed, be Δ t=d * a * Δ S/S the interval time between per refresh for twice;
Described d is that a plurality of users' of the current demonstration books of E-book reader works average per second is read number of words C1, or a plurality of users' of the books works of secondary classification average per second is read number of words C2 under the current demonstration books of the E-book reader works, or a plurality of users' of the books works of one-level classification average per second is read number of words C3 under the current demonstration books of the E-book reader works, or the active user's of the current demonstration books of E-book reader works average per second is read number of words c, or the active user's of books works average per second is read number of words c arbitrarily;
Described a is the current page number of words of the current demonstration books of E-book reader works;
The area that the screen that described Δ S is an E-book reader refreshes at every turn is in pixel;
Described S is the total area of the screen of E-book reader, in pixel.
The present invention has changed the full frame thinking set that refreshes of traditional E-book reader, adopts partial refresh breakthroughly, or claims split screen to refresh, and has so not only shortened and has refreshed the required time at every turn, and provide continuous reading experience for the user.
Embodiment
E-book reader of the present invention, its screen adopt electrophoretic display technology to show.The screen (Electronic Paper) that adopts this display technique does not need to refresh when not changing displayed content.Therefore so-called " refreshing " be meant shown content on the screen that changes E-book reader.
Traditional E-book reader, refresh the Zone Full that all needs to change described screen at every turn, the CPU of E-book reader need calculate the Potential distribution situation of the entire electrode layer of described screen like this, and control the current potential of the entire electrode layer of described screen, thereby make that the displaying contents of described screen is consistent with the Potential distribution of described electrode layer.
Among the present invention, refresh the subregion that only needs to change described screen at every turn, the CPU of E-book reader only need calculate the current potential that refreshes the area relative electrode layer of described screen like this, thereby makes that the displaying contents that refreshes the zone of described screen is consistent with the Potential distribution of described electrode layer.Obviously because the dwindling of the screen area that refreshes, the calculated amount of the CPU of E-book reader, the also corresponding minimizing of control electrode layer institute spended time, thus accelerated to refresh the required time.
For example, the screen of E-book reader evenly can be divided into n horizontal stripe from top to bottom, be called from top to bottom the 1st horizontal stripe, the 2nd horizontal stripe ..., the n horizontal stripe.Once refresh the 1st horizontal stripe, refresh next time the 2nd horizontal stripe ..., refresh the n horizontal stripe the n time, circulate with this.Under the preferred situation, n=2.Under opposite extreme situations, n=screen overall height (in pixel)/current line height (in pixel), promptly refresh line by line this moment.
And for example, the pattern that E-book reader may adopt left and right two hurdle subfields to browse when reading electronic works, the screen of E-book reader from left to right evenly can be divided into m vertical bar, from left to right be called the 1st vertical bar, the 2nd vertical bar ..., the m vertical bar.Once refresh the 1st vertical bar, refresh next time the 2nd vertical bar ..., refresh the m vertical bar the m time, circulate with this.Under the preferred situation, m=2.Under opposite extreme situations, m=screen overall width (in pixel)/current col width (in pixel), promptly refresh by row this moment.Another kind of opposite extreme situations is E-book reader to be revolved to turn 90 degrees read, this moment m=screen overall width (in pixel)/the revolve current line height (in pixel) that turn 90 degrees when using.
For another example, E-book reader can be divided into the screen of E-book reader the grid that n is capable, m is listed as equably when works such as reading caricature, once refresh lattice or many lattice, refresh ensuing lattice or many lattice next time, circulates with this.
Above-mentioned various refresh sequence can be from left to right, from top to bottom, also can be other orders that the user defines in E-book reader.
The total area (in pixel) of the screen of E-book reader is called S, and the area (in pixel) that the screen of E-book reader refreshes at every turn is called Δ s, need to refresh the S/ Δ so and just can make for s time whole screen obtain complete refreshing.
Among the present invention, the user is when reading each books works, the browser script of E-book reader all can be added up number of words a, the time b that the user reads current page of the current page of current shown books works, and calculates the per second that the user reads current page with this and read number of words c=a/b." one page " refers to shown all the elements on the whole screen of E-book reader.With the user to the per second of each page of these books works read number of words c (the 1st page), c (the 2nd page) ..., c (k page or leaf) arithmetic mean in addition, just obtain the user the average per second of these books works read number of words
Consider every E-book reader when showing every books works, shown font type, size possibility difference, the deviation in the time of word counting can being brought thus.The number of words that current page can show when for this reason, the browser script of E-book reader was with default font type, size shows number of words a as standard page.Calculate with standard page like this, the user read these books works average every page reading time d=c * a.
When the user uses E-book reader first, the software of E-book reader can guide the one page or the multipage of one one of user's academic probation or multi-section works, thereby the per second that calculates the user is read number of words c, and read the initial value of number of words c as user's average per second, calculate the user based on this to every page of standard page average reading time of d.Increase along with the user uses the time of E-book reader, the statistics of above-mentioned each numerical value, the calculating of each mean value are also brought in constant renewal in thereupon.
When E-book reader was connected to network, E-book reader was read number of words c with this machine user for the average per second of each books works and is sent to data server on the network.Data server is at each books works, the user of many E-book readers of statistics (is at least 200～300, be preferably more than 1000, the minimum statistics amount of following calculating mean value is herewith) per second that sent read number of words c (user 1), c (user 2) ..., c (user k) and carry out arithmetic mean, thereby the average per second that obtains a plurality of users of these books works is read number of words
Data server carries out secondary classification with each books works, and one-level is categorized as some big classifications for example " swordsman ", " describing love affairs " etc.; Secondary classification is the little classification in the big classification, for example is divided into " passing through ", " fantasy " etc. again in " swordsman " big class.Each books works belongs to an one-level classification at least, can belong to a plurality of one-level classification.Each books works belongs to a secondary classification at least, also can belong to a plurality of secondary classifications.
Data server is at each secondary classification, the per second that receives under this secondary classification that many E-book readers sent one one or multi-section books works read number of words c (books 1), c (books 2) ..., c (books k), read number of words thereby obtain under this secondary classification the average per second of a plurality of users of books works
Data server is at each one-level classification, the per second that receives under this one-level classification that many E-book readers sent one one or multi-section books works read number of words c (books 1), c (books 2) ..., c (books k), thereby obtain the classification of this one-level down the average per second of a plurality of users of books works read number of words
Perhaps, after the average per second that data server calculates a plurality of users of each books works is read number of words C1, the C1 of the multi-section books works identical secondary classification is under got after the arithmetic mean as the average per second reading of a plurality of users of these secondary classification pectus works number of words
And/or the C1 of identical one-level classification multi-section books works down got after the arithmetic mean the average per second reading of a plurality of users number of words as these one-level classification pectus works
When E-book reader is connected to network, the average per second of a plurality of users that the average per second of a plurality of users that data server is also read a plurality of users' of each books works average per second number of words C1 (if any), each secondary classification pectus works is read number of words C2 (if any), each one-level classification pectus works is read number of words C3 (if any) and is sent to each E-book reader, perhaps only sends to the E-book reader with corresponding books works.
Traditional E-book reader refreshes or by (for example user's page turning) of user's manual refreshing at every turn, or the user selects (for example the user is provided with every 5 seconds and refreshes once) of periodic refreshing in E-book reader.
The present invention has increased intelligent refresh mode on the basis of manual refreshing, periodic refreshing, the time Δ t=d * a * Δ S/S under this pattern between per twice screen-refresh.The c of d first these books works of being preferably on the E-book reader to be added up wherein.If the user has just begun to read this books works, E-book reader does not also count the c of these books works, and d second is preferably C1 so.If data server does not also count C1, perhaps data server does not also send to E-book reader with C1, the 3rd of d the is preferably C2 so.If data server does not also count C2, perhaps data server does not also send to E-book reader with C2, and d the 4th is preferably C3 so.If data server does not also count C3, perhaps data server does not also send to E-book reader with C3, the c of d the 5th any books works of being preferably on the E-book reader to be added up so, perhaps built-in acquiescence numerical value in the software of E-book reader.
In other words, the present invention is when the interval time (being the interval time between per twice page turning) of calculating between per refresh for twice, be as the criterion at the reading rate of these books works earlier with this machine user, if not again with a large number of users at these books works or under it average reading rate of secondary classification or one-level classification under it be as the criterion.When books works belong to a plurality of secondary classifications and/or a plurality of one-level is divided time-like, to come top secondary classification and/or first classification is as the criterion, because this ordinary representation goes out the classification of related maximum with these books works; Perhaps, send to E-book reader again with a plurality of C2 of a plurality of secondary classifications under it and/or first classification or after a plurality of C3 carries out arithmetic mean again.
In sum, the method that E-book reader of the present invention refreshes is for provided detailed technical scheme the interval time between the zone of refreshing, per refresh for twice at every turn.The present invention has reduced user's stand-by period in the refresh process, and has made the user sight line can be rested on updated zone, thereby optimized user's reading experience owing to adopted partial refresh.When intelligent page turning (refreshing), the present invention has provided the account form of page turning time according to being worth as reference the average reading time of books works, secondary classification or one-level classification, can bring best reading experience for the user like this.
