Specific implementation mode

Technical scheme of the present invention is further elaborated below in conjunction with Figure of description and specific embodiment.

As shown in Figure 1, the present embodiment provides a kind of synchronous display methods, including：

Step S110：First generation time of the first interrupt signal of the first screen within the current refresh cycle is recorded, and Record second generation time of the second interrupt signal of the second screen within the current refresh cycle；

Step S120：Based on first generation time and second generation time, first interrupt signal is predicted It is poor with generation time of second interrupt signal within next refresh cycle；

Step S130：If the generation time difference is not less than time difference threshold value, first screen and/or described second are shielded Picture refreshing of the screen in next refresh cycle.

The synchronous display method provided in the present embodiment can be applied in the electronic equipment with multiple display screens, alternatively, It is connected in the electronic equipment of multiple display screens.For example, there are two show screen for a mobile phone tool.When multiple screen synch are shown When, pass through the synchronous synchronization for realizing multiple screens two-by-two.For example, when carrying out the simultaneous display of 4 screens, Fig. 1 institutes may be used Show that method realizes the simultaneous display of 4 screens by synchronizing two-by-two.It is a kind of dual-screen electronic device includes screen that Fig. 8, which is shown, S1 and screen S 2.

In the present embodiment, electronic equipment can record the production of the interrupt signal of two screens in the current refresh cycle first The raw time.Herein, the interrupt signal of the first screen is referred to as the first interrupt signal, and the generation time of the first interrupt signal is referred to as First generation time.The interrupt signal of second screen is referred to as the second interrupt signal, and the generation time of the second interrupt signal is referred to as For the second generation time.Interrupt signal is the signal for triggering screen and carrying out picture refreshing, and first interrupt signal is for triggering First screen carries out picture refreshing, and second interrupt signal carries out picture refreshing for triggering the second screen.When in receiving After break signal, display data can be read from the caching of corresponding screen, refresh the picture of screen, to show switching.For example, The display brightness and/or color for refreshing each pixel according to display data, to realize picture refreshing.In the present embodiment, The time that screen receives interrupt signal twice is equal to a refresh cycle.

In the present embodiment, the first screen and the second screen are the screens for needing simultaneous display.First screen and It should be the same that the refresh cycle of two screens is predetermined.For example, the refresh cycle of the first screen is equal to the refreshing week of the second screen Phase., may be inconsistent due to the time precision for the crystal oscillator that the first screen and the second screen connect but in actual control, or Person, time precision is consistent but error is inconsistent etc., cause the duration of the refresh cycle of the first screen and the second screen equal but It is the deviation there is the refresh cycle, for example, the duration of some refresh cycle is shorter or longer than the standard duration of refresh cycle. In another example two screens are used to trigger the time deviation of the crystal oscillator of the generation of interrupt signal, so as to cause the refreshing of two screens The unjustified problem at the refreshing moment in period.Fig. 2 show the actual refresh cycle of one of screen.For example, one A length of T when the standard of refresh cycle, then actually since the timing offset of crystal oscillator can lead to practical duration such as Fig. 2 of refresh cycle It is shown, there is T, T-t1, T+t1 and T+t2 etc..

The first generation time and the second generation time can be recorded in step S110 in the present embodiment.First generation time And second deviation between generation time, it may be determined that go out the difference when the refreshing moment of the first two screen, due to predetermined two screens The refresh cycle of curtain is the same, and this time difference can influence two screens in the time difference of next refresh cycle, for example, meeting It postpones to next refresh cycle；Therefore it can be based on the next refreshing of prediction of poor at the first time and the second time difference in the present embodiment The time difference that the interrupt signal of two screens generates in period.If the generation time difference mistake in next refresh cycle of prediction Greatly, the asynchronous of display switching can be perceived when such as the time difference reaches time difference threshold value by the eyes of user, if then the One screen and the second screen are refreshed also according to the interrupt signal being respectively received, then may be such that user sees two The asynchronous problem of the picture refreshing of screen.In view of this, in the present embodiment, in order to avoid user sees this screen-refresh Nonsynchronous problem, then in next refresh cycle, the picture of at least one screen does not refresh, then next refreshing week Phase, only there are one screen-refresh picture, alternatively, two screens do not refresh, so as to avoid the refreshing moment of two screens Refresh caused by the time difference is excessive asynchronous.

At the same time, since the screen switching of two screens (refresh) was carried out based on the refresh cycle, and screen brush The new refresh cycle be also according to human eye can perceive less than.Similarly, if human eye can perceive the refreshing of two screens not Synchronous, then the time difference of the first interrupt signal and the second interrupt signal that show two screens is sufficiently large, and is presented below as feature：

Interruption of the interrupt signal of the current refresh cycle of one screen with another screen in next refresh cycle is believed Number time difference, can be less than the two screens the interrupt signal of current refresh cycle time difference.

In figure 3, the generation time of the first interrupt signal and the second interrupt signal that vertical line indicates on a timeline.With reference to Fig. 3 is it is found that the first interrupt signal and the second interrupt signal are very close in the generation time of each refresh cycle originally, still With the increase of screen-refresh number, the first interrupt signal and the second interrupt signal are poor in the generation time of the same refresh cycle It is increasing.It is such as obvious very in the generation time of the second interrupt signal of refresh cycle M-1 and the first interrupt signal difference in figure 3 Greatly, the generation time of the second interrupt signal of the first interrupt signal generation time and refresh cycle M-1 of opposite refresh cycle M is more It is close.If at this point, masking the first screen in the refreshing of refresh cycle M-1 and maintaining the second screen in the brush of refresh cycle M-1 Refreshing of new and the first screen in refresh cycle M, it is clear that the first screen can be made in the refresh time and the second screen of refresh cycle M Curtain refresh cycle M-1 refresh time very close to, it is clear that be achieved that synchronous refresh.A secondary screen is being shielded in this mode Digital display after, need adjust simultaneous display refresh cycle counting, so that it may to ensure that subsequent synchronisation is shown.In short, working as Preceding first screen is in refresh cycle M-1 not refresh pictures, and the second screen is in refresh cycle M-1 refresh picture, the first screen and Two screens refresh in refresh cycle M, then can make the generation time difference more adjunction of the interrupt signal of two screen-refresh pictures Closely.For example, the first screen should show that xth frame picture, the second screen are shown in refresh cycle M in refresh cycle M originally Y frame pictures, but since the time difference is excessive, the first screen does not refresh in refresh cycle M-1, i.e., does not show that xth frame is drawn Face；In the generation time refresh picture of the interrupt signal of refresh cycle M, xth frame picture is shown, and at this point, the brush of the second screen The interrupt signal in new period M-1 also produces, the second screen display y frame pictures.Obviously at this point, not only avoiding the first screen At the same time picture tearing caused by asynchronous refreshing and flower screen problem with the second screen pass through the refreshing week of the first screen The shielding of phase M-1 refreshes, and to be more nearly with correspondence xth frame picture and y frame picture display times, to real Simultaneous display is showed.

If therefore the generation time difference of two interrupt signals in next refresh cycle in the present embodiment is more than time difference threshold Value, shields the refreshing of at least one screen, can not only solve the problems, such as that two screen-refresh that next period generates are nonsynchronous, Simultaneously can also not refreshing by least one screen so that two screen displays correspond to the interrupt signal of picture when It is closer on countershaft.

In some embodiments, the step S120 may include：Calculate the first interrupt signal and of current refresh cycle The generation time of two interrupt signals is poor, which can be directly as the first interrupt signal of next refresh cycle and The generation time of two interrupt signals is poor.

In further embodiments, the step S120 may include：

Calculate the first interrupt signal of current refresh cycle and the time difference tx of the second interrupt signal；

The variation tendency of the first interrupt signal and the second interrupt signal generation time difference is counted, then tx+ty is under prediction The time difference of one refresh cycle, ty is offset identical with the variation tendency, if the variation tendency is to increase, institute It is positive value to state ty, if the variation tendency is to reduce, the ty is negative value.

In some embodiments, the ty can be preset value, and in further embodiments, the ty can be what dynamic calculated Value, for example, ty=tx/N；Wherein, the N is the number for the refresh cycle being had been subjected in current statistic window.

In further embodiments, as described in Figure 4, the step S120 may include：

Step S121：Based on first generation time and second generation time, determined for first time difference；

Step S122：First based on first interrupt signal practical generates the of period and second interrupt signal In two practical generation periods, determined for second time difference；

Step S123：Based on first time difference and second time difference, predict that the generation time of next refresh cycle is poor.

In the present embodiment, the predetermined generation period of first interrupt signal and second interrupt signal should be equal to Refresh cycle, but due to crystal oscillator of the first interrupt signal of triggering and the second interrupt signal etc. and its time deviation, can make The practical cycle phase that generates deviates the predetermined generation period.

Here first it is practical generate the practical generation period that the period is the first interrupt signal, second practical generate the period and is The practical generation period of second interrupt signal.The practical deviation for generating the period and making a reservation for the generation period is the essence due to hardware itself The problems such as delay of degree and inherent limitation and software, is caused.For example, the first interrupt signal and the second interrupt signal is predetermined It is 16.7ms to generate the period, but the first practical generation period may swing in 16.5ms between 16.7ms；And second is real The border generation period may swing between 16.7ms to 17ms.And in next refresh cycle, first interrupt signal and The practical generation period of two interrupt signals is also uncertain, then at this time can according to historical record, count the first interrupt signal and In the second interrupt signal respective practical generation period, it is based on the practical generation period, calculated for second time difference.

When in step S123 by the generation of next refresh cycle is gone out according to first time difference and the second time difference unified budget Between it is poor；For example, absolute value of the difference and the sum of absolute value of the difference when second when solving first, when obtaining the generation of next refresh cycle Between it is poor.In the present embodiment, it is clear that the time difference that the first interrupt signal and the second interrupt signal have generated is not only allowed for, and And also according to the practical generation period of two interrupt signals, it is contemplated that go out the time difference that can be increased newly within next refresh cycle (i.e. Second time difference) so that the generation time of prediction is poor, and the time difference more adjunction is actually generated within next refresh cycle Closely, so that prediction result is more accurate.If prediction result is more accurate, two screen-refresh on the one hand can be avoided in advance Asynchronous problem, on the other hand, it is possible to reduce unnecessary refreshings caused by prediction result is inaccurate shields.

Optionally, the step S122 may include：

Based on the described first practical extreme value for generating the period and the second practical extreme value for generating the period, described the is determined Two time differences.

The reality generates period extreme value：It is practical to generate period maximum and practical generation period minimum.For example, The practical generation period of first interrupt signal may swing in 16.5ms between 16.7ms, then 16.5ms is the practical generation period Minimum；16.7ms is practical generation period maximum.

The step S122 may include：

The time difference of the described first practical maximum for generating the period and the described second practical maximum for generating the period is calculated, Obtain period 1 deviation；

The time difference of the described first practical minimum for generating the period and the described second practical maximum for generating the period is calculated, Obtain second round deviation；

The time difference of the described first practical maximum for generating the period and the described second practical minimum for generating the period is calculated, Determine period 3 deviation；

The time difference of the described first practical minimum for generating the period and the described second practical minimum for generating the period is calculated, Determine period 4 deviation；

It is inclined from the period 1 deviation, the second round deviation, the period 3 deviation and the period 4 Select maximum value as second time difference in difference.

Assuming that the predetermined generation period of the first interrupt signal and the second interrupt signal is 16.7ms, but the first practical production The raw period may swing in 16.5ms between 16.7ms；And the second practical generation period may put between 16.7ms to 17ms It is dynamic；Then period 1 deviation is 17-16.7=0.3ms；Second round deviation is 17-16.5=0.5ms, and period 3 deviation is 16.7-16.7=0ms；Period 4 deviation is 16.7-16.5=0.2ms.By comparing it is found that second round deviation is maximum Value, then second time difference was equal to second round deviation at this time, and was equal to 0.5ms.

After calculating period 1 deviation to period 4 deviation, maximum value can be selected from this 4 periodic deviations As second time difference, to participate in the calculating of the generation time difference of two interrupt signals of next refresh cycle.Using this Mode, the maximum generation time that can calculate two interrupt signals of next refresh cycle is poor, if maximum generation time difference is all small In time difference threshold value, it may be considered that user perceives the nonsynchronous problem of refreshing when next refresh cycle is not in refreshing. If maximum generation time difference is not less than time difference threshold value, it is nonsynchronous to may be such that user leads to the problem of refreshing, then It can be by shielding the refreshing of at least one screen, to refresh nonsynchronous ask to greatest extent to avoid user from perceiving Topic, promotes the reliability of simultaneous display.

Optionally, the step S122 may include：

Determine the first calculated value, wherein if the probability of occurrence of the described first practical maximum for generating the period is not less than institute The probability of occurrence of the first practical minimum for generating the period is stated, then first calculated value is the very big of the first practical generation period Otherwise value is the described first practical minimum for generating the period；

Determine the second calculated value, wherein if the probability of occurrence of the described second practical maximum for generating the period is not less than institute The probability of occurrence of the second practical minimum for generating the period is stated, then second calculated value is the very big of the second practical generation period Otherwise value is the described second practical minimum for generating the period；

Based on the period 1 value and the second week time value, second time difference is calculated.

It in the present embodiment, can be according to the probability of occurrence of the first actual cycle and the extreme value of the second actual cycle, selection ginseng In this case on the one hand the first calculated value and the second calculated value calculated with second time difference has considered and has currently generated First time difference, second time difference was on the other hand calculated based on the probability of occurrence of statistics so that result of calculation is wanted with actual capabilities The duration of generation is more nearly, so that the prediction result of next refresh cycle is more accurate.

Optionally, the step S122 further includes：Determine that the described first practical mean value for generating the period is third calculated value； Determine that the described second practical mean value for generating the period is the 4th calculated value；Alternatively, determining in the described first practical generation period Value is third calculated value；Determine that the described second practical intermediate value for generating the period is the 4th calculated value；Based on the third calculated value And the 4th calculated value, calculate second time difference.It is calculated in the present embodiment in order to simplify, directly selects practical generation week Calculating of the mean value or intermediate value of phase as second time difference, has the characteristics of easy operation.

Optionally, the step S130 may include it is following it is several in any one realization method：

Mode one：

The step S130 may include：

If the generation time difference is not less than the time difference threshold value, when second generation time is generated earlier than described first Between, shield the picture refreshing of the second screen described in next refresh cycle.If current first generation time is generated earlier than second Between, then show that the first interrupt signal is earlier than the second interrupt signal within the current refresh cycle, in the production of next cycle interruption signal The raw time can also continue this rule, if shielding interrupt signal generates screen-refresh earlier, directly shield the first screen Refresh.

Mode two：

The step S130 may include：

If the generation time difference be not less than the time difference threshold value, and the first generation time be later than it is described second generate when Between, picture refreshing of shielding first screen in next refresh cycle.In this programme shielded in the current refresh cycle The refreshing of the later screen of interior interrupt signal.

Mode three：

The step S130 may include：

If the generation time difference is not less than the time difference threshold value, and second generation time is generated earlier than described first Time, picture refreshing of shielding second screen in next refresh cycle.

Mode four：

The step S130 may include：

If the generation time difference is not less than the time difference threshold value, while shielding first screen and second screen In the picture refreshing of next refresh cycle.

Optionally, the step S130 may include：

If the generation time difference is not less than the time difference threshold value, in the first display caching area for shielding first screen Update of first display data in next refresh cycle, and/or, in the second display caching area for shielding second screen Update of second display data in next refresh cycle；Wherein, first display in first display caching area Data are used for the picture refreshing for first screen, and second display data in second display caching area is for supplying The picture refreshing of second screen.

In the present embodiment by shielding not brushing for display data in the first display caching area and/or the second display caching area Newly, what display screen was read from caching is identical display data with the current refresh cycle, to reach the work that shielding refreshes With.

It can refresh as usual in also some embodiments aobvious in first display caching area and the second display caching area Registration evidence is only that the first screen of shielding and/or the second screen read display data from caching and carry out picture refreshing.

In other embodiments, shielding refreshes and can also be：Both the update without display data in caching, simultaneously Screen does not also read data from the caching and is refreshed.

Optionally, the step S130 may include following operation：

Picture refreshing of first screen in next refresh cycle is shielded, and shields first screen next The picture refreshing of refresh cycle includes：The first display data is shielded in the first display caching area of first screen under described The update of one refresh cycle, first display data in first display caching area are used for the picture for first screen Face is refreshed；

Picture refreshing of second screen in next refresh cycle is shielded, and shields second screen described The picture refreshing of next refresh cycle includes：The second display data is shielded in the second display caching area of second screen in institute The update of next refresh cycle is stated, second display data in second display caching area is used to supply second screen Picture refreshing.

Optionally, the step S110 may include：

The first generation time of n-th of first interrupt signal is recorded in current record time window, and described in record The second generation time that n-th of second interrupt signal of the second screen generates；Wherein, it interrupts for described n-th described first Signal is the interrupt signal of the current refresh cycle of first screen；N-th of second interrupt signal is described the The interrupt signal of the current refresh cycle of one screen；N is positive integer；In embodiments of the present invention, it can interrupt and believe by first Number and the second interrupt signal the serial number in time window is recorded at one to determine the interrupt signal for belonging to the same refresh cycle.Institute Step S120 is stated to may include：The first generation time based on described n-th first interrupt signal and n-th described described Second generation time of two interrupt signals, first interrupt signal and described second for predicting next refresh cycle are interrupted The generation time of signal is poor.The record time window includes at least one refresh cycle, usually the integral multiple brush The new period.

In some embodiments, the step S110 further includes：

If the generation time difference is not less than time difference threshold value, described first is recorded in next record time window and interrupts letter Number the first generation time, and when recording in the next record time window the second of second interrupt signal and generating Between.

If the generation time difference for recording the first interrupt signal and the second interrupt signal in time window at one has equalized to Or be more than time difference threshold value, then next record time window is entered, the weight to the first interrupt signal and the second interrupt signal is started New record renumbers.It, can be to avoid by recording the statistics of the first interrupt signal and the second interrupt signal in time window It is not the calculating of the generation time difference of the interrupt signal of the same refresh cycle, the calculating for improving generation time difference again is accurate Degree.

As shown in figure 5, the method further includes in the present embodiment：

Step S140：In next refresh cycle, it is aligned the generation of first interrupt signal and the second interrupt signal Time.For example, the step S140 is executed after the step S130, if being not less than time difference threshold in the generation time difference Value shields first screen and/or second screen after the picture refreshing of next refresh cycle, the method Also wrap the step S140.

If the generation time difference predicted in next refresh cycle between the first interrupt signal and the second interrupt signal is excessive, While shielding the first screen and at least one of refreshing of the second screen, when at least adjusting the generation of an interrupt signal Between.For example, in some embodiments, adjusting the generation in the interrupt signal of the screen of next refresh cycle inner shield refreshing Time so that the first interrupt signal and the second interrupt signal after adjustment can be aligned on a timeline after the adjustment so that The first interrupt signal of next refresh cycle and the second interrupt signal have better time synchronization effect under.For example, current brush The new period is x-th of refresh cycle, and next refresh cycle is the (x+1)th refresh cycle, under the next refresh cycle be xth+2 Refresh cycle.The alignment of the first interrupt signal and the second interrupt signal on a timeline is carried out in the (x+1)th refresh cycle, can be made It obtains and so that the first interrupt signal is more synchronous with the generation time of the second interrupt signal in+2 refresh cycles of xth.For example, passing through An adjust instruction is sent to the generation circuit of the first interrupt signal and/or the second interrupt signal, which makes first Shifting to an earlier date or postponing at least one of interrupt signal and the second interrupt signal interrupt signal generates, the first interrupt signal and second The adjustment amount of the generation time of interrupt signal can be determined based on aforementioned first time difference.For example, the of the current refresh cycle Between one interrupt signal and the second interrupt signal first when a length of 15ms, and it is predetermined to generate the period be 16.7ms, first, under The adjustment of one refresh cycle generates the generation time of the first interrupt signal earlier, can be by by the first of the lower lower refresh cycle Interrupt signal postpones 1.7ms backward so that the first interrupt signal generation time of next refresh cycle under is interrupted with second to be believed Number generation time it is consistent, with reduce two interrupt signals generation time difference be more than time difference threshold value probability.Assuming that in this reality The refreshing for applying shielding corresponding second screen of the second later interrupt signal of generation time within the current refresh cycle in example, then may be used To adjust the generation time of the second interrupt signal in the (x+1)th refresh cycle, such as when the generation of second interrupt signal in advance Between so that do sth. in advance 1.7ms etc. forward in the generation time of the second interrupt signal of+2 refresh cycle of xth.In the present embodiment individually It adjusts an interrupt signal and can be equal in the adjustment time amount of the generation time of+2 refresh cycle of xth and predetermined generate the period and the The difference of one time difference.When can also adjust the generation of the first interrupt signal and the second interrupt signal simultaneously in some embodiments Between.For example, when shielding the refreshing of the first screen and the second screen simultaneously in step s 130, the first interruption letter can be adjusted simultaneously Number and the second interrupt signal generation time so that realize two interrupt signals pair on a timeline in+2 refresh cycle of xth Together.

As shown in fig. 6, the present embodiment provides a kind of synchronous display apparatus, including：
