Then table 1 is referred to.The conventional refresh mode of electric paper display in the display known technology of table 1.
Table 1
In the case where driver 230 gives fixed voltage, the refresh mode of electric paper display mainly divides
It is refresh all and Local hydrodynamic unit both of which.Refresh all may include INIT (Initialize) pattern again
And GC (Grayscale clear) pattern.INIT patterns refer to complete cls, and its shortcoming is that elapsed time is long (about
It it is 2000 milliseconds).GC patterns refer to and all refreshed all pixels or removed, although and GC pattern phases
It is time-consuming compared with INIT patterns shorter, but its shortcoming is more serious to flash.However, INIT patterns and
It is few that the advantage of GC patterns is all produced ghost.Additionally, Local hydrodynamic unit may include GU (Grayscale
Update) pattern.GU patterns refer to will need the pixel for changing directly to refresh to specified grey decision-making, and its is excellent
Point is for flicker is less, time-consuming shorter, but its shortcoming is that the ghost for producing is more.
Refer to Fig. 3 A~3C.Fig. 3 A~3C shows that the Electronic Paper according to one embodiment of the invention shows
Show the schematic diagram that the ghost of device is produced.Fig. 3 A represent electric paper display current picture shown at present.

And, in order to provide user preferably experience, when processor 220 is selected in the way of Local hydrodynamic unit
When showing next picture, then ghost phenomenon as shown in Figure 3 C is likely to occur.
Part on sideline 331 and sideline 332, because driver 230 only can refreshing pixels value hair
The raw region for changing, therefore the pixel information of all pixels according to next picture 320, processor 220 is only
It is white that black region 311 is refreshed, and it is black that the white portion 312 of part is refreshed, and by
Still it is white in next picture 320 in white portion 313, therefore driver 230 can't refresh the area
Pixel corresponding to domain.However, being powered in the electrode corresponding to black region 311 and corresponding to white area
In the case that the electrode in domain 313 is not powered, by after multiple refreshing, positioned at black region 311 with
Microcapsules between white portion 313 can then produce the effect of transverse electric field so that black grain in microcapsules
Son and white particles skewness, and then cause the generation in sideline 331 and sideline 332.
Above-mentioned in order to solve the problems, such as, according to one embodiment of the invention, processor 220 is for refreshing block
The adjacent pixel of marginal position processed to eliminate transverse electric field.For example, Fig. 4 displays basis
The schematic diagram that the synchronous adjacent pixel to marginal position described in one embodiment of the invention is updated.Such as Fig. 4
Shown, black region represents the region that next picture can be refreshed, and hatched example areas represent to go out
The pixel of existing transverse electric field.In this embodiment, although the pixel value of hatched example areas does not change,
But driver 230 gives appropriate voltage still according to the pixel value corresponding to hatched example areas, make its microcapsules
Middle black particles can correctly maintain the configuration of script with white particles, to avoid being subject to the shadow of transverse electric field
Ring.
Fig. 5 A, Fig. 5 B show the synchronous adjacent picture to marginal position according to another embodiment of the present invention
The schematic diagram that element is updated.According to another embodiment of the present invention, when processor 220 only refreshes certain every time
During one particular block, the hatched example areas being made up of tetra- points of A, B, C, D as shown in Figure 5 A,
Because driver 230 only can give voltage to refresh to electrode corresponding in hatched example areas, therefore
After refreshing several times, the marginal position part of hatched example areas can engender the situation of transverse electric field.And
It is above-mentioned in order to solve the problems, such as, in the refresh picture of driver 230 up to a predetermined number of times (such as 2~3 times) it
Afterwards, in the case of the display content for not influenceing hatched example areas, processor 220 changes given zone a littlely
The marginal position of block, for example, change into A ', B ', C ', D ' by the coordinate of tetra- points of A, B, C, D,
The microcapsules corresponding to the adjacent pixel of built-in edge position should be so effectively prevented from and produce laterally electricity
The situation of field.
Additionally, on darker regions (such as region 333) color not enough depth and light areas (such as region
334) not shallow enough the problem of color, due in order to reach power saving and provide user preferably experience
Purpose, therefore driver 230 in refresh block 333 and region 334 when, it is possible that giving electricity
The situation that the undertension or refresh time of pole fall short of so that the pixel value corresponding to the region occurs

Display screen, thus processor 220 can command-driven device 230 to extend refresh time in the way of avoid ghost
The appearance of shadow.Or, when user continually operates electric paper display, processor 220 can be ordered
Driver 230 is above-mentioned to solve the problems, such as to put forward high-tension mode.
According to one embodiment of the invention, the mode for extending refresh time can be to come by using different patterns
Strengthen the renewal of pixel value.For example, under GC patterns, when pixel value is intended to from the first pixel value more
When newly to the second pixel value, its mode for updating is：First pixel value → white (black) → black picture of (white) → second
Element value.But when pixel value is updated to complete white (black) from the first pixel value, then can using INT patterns come
It is updated, although the time of renewal is slightly long, the first pixel value can be efficiently reduced and be updated to complete white (black)
Produced ghost, to obtain preferably image quality.Additionally, when pixel value from white (black) → black (white),
Also may be selected to be refreshed using INT patterns, with more completely by the ghost produced by the first pixel value
Eliminate so that last image quality closer to completely use INT patterns image quality.
According to another embodiment of the present invention, in the case where refresh time is not extended, processor 220 also may be used
The distribution situation of black particles and white particles in microcapsules is adjusted by putting forward high-tension mode.Citing
For, in the case where voltage is V, driver 230 must be spent in the way of foregoing extension refresh time
The time for taking (T+T ') correctly can be just adjusted to correct value pixel value.However, not extending refreshing
In the case of time, processor 220 can command-driven device 230 raise voltage to (V+V ') volt with plus
The movement of black particles and white particles in fast microcapsules, and then reach the effect of adjustment pixel value.It is worth
It is noted that as previously described, because the display efficiency of electric ink can be because manufacturing process be different
Difference, therefore processor 220 is when the relation of voltage and time is calculated, the mode that can also be tabled look-up is determined
The magnitude of voltage of raising.
