Abstract
The invention discloses a refreshing method of an electronic ink screen. A monitor is added to a drawing device of the electronic ink screen for monitoring the frame drawing updating frequency of all the electronic ink screen; when the updating frequency is higher than a threshold, the monitor emits a global notification to enable a refreshing manger to refresh the electronic ink screen by use of a refresh mode; and when the updating frequency is lower than a threshold, the monitor emits the global notification to enable the refreshing manager to refresh the electronic ink screen by use of a second refresh mode. Whether two preset refresh modes need to be converted is flexibly determined according to the frame drawing updating frequency of the electronic ink screen in the application process of a user. When a static image is watched for long time, a system determines that replacement of a refreshing mode is unnecessary and an original refreshing mode is always maintained. In case of animations or other images with quite high local refreshing frequencies, the system automatically converts the original refreshing mode into the first refreshing mode, high-frequency refreshing is automatically started, and the influence exerted by a ghost image on reading of the user is reduced.
Description
Technical field
The present invention relates to a kind of method for refreshing of screen, particularly relate to a kind of method for refreshing of electronic ink screen.
Background technology
Electronic ink screen is made up of many electric inks, and these electric inks can regard the appearance of capsule one by one as.Liquid charge is had, wherein positive charge dye white, negative charge dye black inside each capsule.When we give generating positive and negative voltage in side, the liquid with electric charge will be attracted and is repelled respectively, and like this, each pixel just can display white or black.
Refreshing due to electric ink is discontinuous, has refreshed each time and just can keep present figure, also still preserves even if pull out battery.Change displaying contents, will carry out taking turns refreshing to screen, to show new content, under screen not brush news, content can show lastingly and not need additional electrical energy, so the flying power of electric paper book all calculates with refreshing frequency.
The refreshing mode of early stage electric paper book is all the mode adopting full frame refreshing, the shortcoming of this mode be exactly refresh rate comparatively slowly, page turning situation slowly can be found during use, turn over the time that one page often needs 2-3 second even longer.And the overall situation refreshes, each pixel can experience one complete black in entirely white color change process, the sensation that people's screen one dodges can be given.
In order to solve the problem, some electronic ink screens have employed the mode of Local hydrodynamic unit, and only internally hold vicissitudinous place when refreshing and refresh, the unconverted region of content is not then refreshed, and can improve refresh rate like this.When employing this kind of Local hydrodynamic unit mode, after page turning, some ghosts of browsing pages before screen also can stop, after repeatedly Local hydrodynamic unit, the ghost of picture is more, thus impact is read.
In order to overcome this problem, some electronic ink screens adopt Local hydrodynamic unit to refresh with the overall situation mode combined, after Local hydrodynamic unit number of times is more, re-use full frame refreshing, ghost on screen is removed, thus page turning time length can be avoided and dodge the problem of shielding, the problem that ghost too much affects reading can be overcome again.
But above-mentioned refreshing mode still has problems.When needs display animation, due to picture change frequency quickly, its Local hydrodynamic unit number of times is frequent, and ghost is serious, display effect extreme difference.The switching of dynamic fast scene, is refreshed by the interspersed slow-footed overall situation and eliminates ghost, will greatly affect the continuous display of animation, produce card and pause, therefore adopt this mode also cannot solve the display problem of animation.In addition, for the consideration of display effect, for making electronic ink screen have preferably display effect, have certain requirement to its grey exponent number, electric paper book product ash exponent number is on the market based on 8 grades and 16 grades at present.The Local hydrodynamic unit of electronic ink screen is also for there being the Local hydrodynamic unit of corresponding GTG transition, when the animation that electronic ink screen needs display variation frequency fast, its not only picture display data processing amount large, also the problem that refresh rate is slow can be caused, more enter the display effect that have impact on animation of, make animation be difficult to normal display.
Summary of the invention
In order to solve the problems of the technologies described above, automatically adapt to the electronic ink screen method for refreshing of the fast cartoon picture display of refreshing frequency and normal pictures while that the object of the invention being to provide a kind of, to take into account display effect and the display speed of electronic ink screen.
The method for refreshing of a kind of electronic ink screen of the present invention, is characterized in that, comprise the steps:
In the renderer of electronic ink screen, add audiomonitor, the frame monitoring whole electric ink draws renewal frequency; When renewal frequency is higher than threshold value, audiomonitor sends overall situation notice makes refresh manager use the first local refresh mode to refresh electronic ink screen; When renewal frequency is lower than threshold value, audiomonitor sends overall situation notice makes refresh manager use the second local refresh mode to refresh electronic ink screen; Electronic ink screen also arranges overall refresh switch, and when overall refresh switch triggers, refresh manager uses overall refresh mode to carry out overall situation refreshing to electronic ink screen;
The first described local refresh mode is: do not have GTG transition, only have the Local hydrodynamic unit of black and white second order;
The second described local refresh mode is: the Local hydrodynamic unit having GTG transition.
The method for refreshing of electronic ink screen of the present invention, when display frame draws renewal frequency lower normal pictures, the frame that audiomonitor in renderer can monitor electric ink draws renewal frequency, time lower for frame drafting renewal frequency (lower than threshold value), there to be the Local hydrodynamic unit mode redraw of GTG transition, can realize the switching of display frame fast, picture switch speed is fast, and picture is clear, display effect is good.After repeatedly image switching (as page turn over operation etc.), when screen exists more ghost, by starting overall refresh switch, the overall situation can be started and refresh, ensure display effect to eliminate ghost.When the animation that display frame drafting renewal frequency is higher, the frame that the audiomonitor in renderer can monitor electric ink draws renewal frequency higher than threshold value, and now electronic ink screen can automatically switch to does not have GTG transition, only has the Local hydrodynamic unit mode of black and white second order.It significantly reduces the data volume of each picture in animation by the Local hydrodynamic unit mode of black and white second order, than the refreshing having the refreshing of GTG transition to realize each picture faster, thus the display demand of Rapid Variable Design picture can be adapted to, animation can be adapted to, and the display of dynamic page needs, and there will not be the flicker of picture.
Visible, the method for refreshing of electronic ink screen of the present invention, frame according to the electric ink in the use procedure of user draws renewal frequency, automatically the Local hydrodynamic unit pattern adopted can be controlled flexibly, by the switching of the first refresh mode and the second refresh mode, automatically can adapt to the display of normal pictures and dynamic menu very well, and display effect and the display speed of normal pictures and dynamic menu can be taken into account.
Embodiment
The method for refreshing of a kind of electronic ink screen of the present invention, comprises the steps:
In the renderer of electronic ink screen, add audiomonitor, the frame monitoring whole electric ink draws renewal frequency; When renewal frequency is higher than threshold value, audiomonitor sends overall situation notice makes refresh manager use the first local refresh mode to refresh electronic ink screen; When renewal frequency is lower than threshold value, audiomonitor sends overall situation notice makes refresh manager use the second local refresh mode to refresh electronic ink screen.It is even higher that threshold value for judging whether to change refresh mode can be set to 10fps-20fps.Thoroughly eliminate ghost impact in order to satisfied, electronic ink screen also arranges overall refresh switch, and when overall refresh switch triggers, refresh manager uses overall refresh mode to carry out overall situation refreshing to electronic ink screen.
In order to reduce unnecessary frequent transitions refresh mode, when renewal frequency is lower than threshold value, if when renderer free time is greater than setting-up time, audiomonitor does not send overall situation notice.
Suppose, set the threshold to 15fps, the frame number namely not having draw second is 15 frames; Setting-up time is 1 minute, i.e. the correlative value of free time; The current using forestland of user is the second refresh mode.The program used as user needs the frequency refreshed to reach 15.5fps, and audiomonitor detects that refresh rate has exceeded threshold value.Audiomonitor sends overall situation notice, and refresh mode is converted to the first refresh mode from the second refresh mode after receiving overall situation notice by refresh manager.
Under the first refresh mode duty, if the software refreshing rate that user uses there occurs change, such as refreshing frequency drops to 14.5fps, but rises to again the frequency of 15fps or higher in 1 minute.Such audiomonitor judges not exceed setting-up time lower than the free time of threshold value, can not send overall situation notice.Refresh manager does not receive overall situation notice, so can maintain the first refresh mode work always.
If the software refreshing rate that user uses drops to below 15fps, and does not all exceed threshold value in 1 minute, then audiomonitor judges to have exceeded setting-up time lower than the free time of threshold value, thus sends overall situation notice.Refresh mode is converted to the second refresh mode from the first refresh mode after receiving overall situation notice by refresh manager.
First refresh mode and the second refresh mode are all the refresh modes of Local hydrodynamic unit, difference is that the first refresh mode does not have GTG transition, only has the Local hydrodynamic unit of black and white second order, such as electric ink is controlled 0 or F two GTG redirects, this pattern is applicable to changing fast screen drawing, such as animation and the advertisement of jumping screen etc.Second refresh mode adopts the Local hydrodynamic unit having GTG transition, such as electronic ink screen is controlled 0,4,8, redirect between the quadravalence gray scale of F or six higher rank/eight rank gray scales, this pattern is applicable to the screen drawing changing slow no change even always, such as, when seeing novel, be all generally within 3 minutes, just need to refresh once.The image transition adopting the second refresh mode to demonstrate can be more comfortable, adopt the first refresh mode to draw ghost more less, audiomonitor controls the conversion of two kinds of patterns in real time based on the presently used situation of user.
Local hydrodynamic unit will inevitably produce the problem of ghost, in order to thoroughly solve ghost, the present invention also arranges overall refresh switch at electronic ink screen, described overall refresh switch can be trigger manually, or notifies that refresh manager triggers automatically when audiomonitor reaches setting value according to the number of times of Local hydrodynamic unit.
When needs display third party software, first system is set up packet to third party software and is stored the database of packet; Record this third party software in packet and draw whether adopt the first refresh module.Generally packet includes following data:
Bag name: major key, for identifying corresponding software;
Version number: the software of different editions number may alter a great deal by interface element, therefore record version number as adaptation optimize according to necessary;
Assembly name: can be refined in assemblies different in software and carry out different flushing policy;
Whether enable animation;
Whether use automatic first refresh mode.
In order to user can use identical personal settings by striding equipment, database is connected with cloud server, and database can carry out backing up and recovering to cloud server.User sets the refresh parameter being applicable to individual in device A, such as setting threshold value is 17fps, 18fps or 19fps; The setting-up time of contrast free time is personal preference's parameters such as 2 minutes, 3 minutes or 10 minutes.Device A backs up personal set by cloud server, and user is when use equipment B, and from cloud server, the personal set backed up before can be returned to equipment B as required, such device A and equipment B just can use same group of setup parameter.Exempt user more exchange device time all to set personal preference at every turn and lose time.
