Detailed description of the invention
Refer to the schematic diagram that Fig. 1, Fig. 1 are the embodiment of the present invention one display system 10.As it is shown in figure 1, display system 10
Include a transmission ends 100, one drive circuit 102 and a display floater 104.Transmission ends 100 can be the central authorities of mobile device
Processor or the device of other offer video data, and be applicable to come according to the command mode of mobile processor interface standard criterion
Output data, say, that only when video data DIN has renewal just output display data DIN to drive circuit 102.Drive
After galvanic electricity road 102 receives the video data DIN that transmission ends 100 is exported, the frame updating frequency of display floater 104 will be determined,
And change data with output driving signal DRV to driving display floater 104 to show.Wherein, display floater 104 is to be
Such as Organic Light Emitting Diode (OLED) panel or thin film transistor (TFT) (TFT) panel etc., and it is not limited in this.
Specifically, drive circuit 102 include detecting unit 110, internal storage location 112, output unit 114,
One presets adjusted value 116, control unit 118 and a seamless switching unit 120.In order to be illustrated more clearly that drive circuit
The function mode of 102 internal datas, please also refer to the signal of the example that Fig. 2, Fig. 2 are related data in drive circuit 102
Figure.As in figure 2 it is shown, video data DIN system is formed by picture data IMG0, IMG1, IMG2, IMG3, because of transmission ends 100 only
Just export to drive circuit 102 when video data DIN has renewal, so drive circuit 102 meeting sequentially DIYU time point t0,
Picture data IMG0, IMG1, IMG2, IMG3 are write the picture represented to solid box in internal storage location 112(i.e. figure by t1, t4, t6
Data IMG0, IMG1, IMG2, IMG3), wherein internal storage location 112 be can be static random access memory (SRAM) or dynamically with
The storing media of machine access memory (DRAM) etc..It addition, picture data does not update (empty in figure when time point t2, t3, t5
Picture data IMG1, IMG2 of wire frame representation), in order to represent that transmission ends 100 does not outputs data to drive when showing static data
Galvanic electricity road 102, drive circuit 102 need to persistently export to display floater by the data that internal storage location 112 stores in advance and show.
Meanwhile, when time point t0, t1, t4, t6, detecting unit 110 because of detect picture data IMG0, IMG1, IMG2,
IMG3 writes to internal storage location, therefore produces a control signal CTL notice and have renewal to control unit 118 video data, so control
It is higher renewal frequency f_hi(such as 60Hz that unit 118 processed can export target adjustment frequency FC), to show relatively Gao Gengxin frequency
Dynamic data.When time point t2, t3, t5, control unit 118 learns video data the most more by controlling signal CTL
Newly, further according to default adjusted value 116, to export target adjustment frequency FC be relatively low renewal frequency f_lo(such as 50Hz), from
And reduce renewal frequency to show the static data of low renewal frequency.It is interesting to note that presetting adjusted value 116 is record display surface
The minimum frame updating frequency of institute of plate manufacturer specification, be primarily due to display floater because of processing procedure different from characteristic, it shows electricity
The charged pressure retainable time is the most different, therefore need to utilize storing media such as read only memory (ROM), flash memory (Flash ROM) etc.
Store the minimum frame updating frequency of record display floater, thereby, when control unit 118 exports target adjustment frequency FC, permissible
Preset the foundation that adjusted value 116 is minimum renewal frequency.
Then, target adjustment frequency FC is output as frame updating frequency FR by seamless switching unit 120, and works as target adjustment
Frequency FC is adjusted by Gao Gengxin frequency f_hi when switching to low renewal frequency f_lo, understands because of reducing frame updating frequency rapidly
Make human eye discover film flicker or response speed reduces, therefore produce in the way of gradually reducing and export frame updating frequency
FR.Therefore, frame updating frequency FR will can be expected from renewal frequency f_hi by seamless switching unit 120 in time point t2, t3
(such as 60Hz) switches to renewal frequency f_lo(such as 50Hz) time, first progressively switch to f_mid(such as 55Hz) after switch to f_lo again
(such as 50Hz).Finally, output unit 114 exports the picture data stored by internal storage location 112 according to frame updating frequency FR, and
Produce and drive signal DRV to drive display floater 104 to show.
Consequently, it is possible to whether drive circuit 102 has write to internal storage location 112 by detecting video data DIN, obtain
The renewal frequency of the video data DIN that transmission ends 100 is exported, and then can dynamically adjust reduction frame updating frequency FR, mat
This can reduce the power consumption of display system 10 and reach power saving.
