It is to be worn on limbs or be embedded in the wearable device in medicated clothing, jewelry, accessory, it is also possible to be
Other have the intelligent electronic device of display function.
Referring to shown in Fig. 1, the display drive method of the present embodiment includes:
S11: processor produces and output video image data；
S12: judge whether vedio data is tableaux data；
So-called vedio data is that tableaux data refer to vedio data at interval in advance
The image of the corresponding display of fixed cycle (following a period of time) is tableaux, its process include but not
It is limited to: obtain the first picture that vedio data shows in current time correspondence, according to predetermined week
The picture that vedio data correspondence is shown by the phase carries out sectional drawing to obtain second picture, compares first
Picture is the most identical with second picture, if identical, then judges that vedio data is as tableaux
Data；If it is not the same, then judge that vedio data is as moving picture data.
If it is determined that vedio data is moving picture data, then perform step S13 and S14；If
Judge that vedio data as tableaux data, then performs step S15 and S16.
S13: processor is to driving chip output video image data；
The moving picture data received is exported by S14: driving chip according to clock signal period
Carry out brush screen to display floater to show；
S15: processor stops to driving chip output video image data；
Processor is after driving chip output video image data, and driving chip can will receive
Vedio data caches, in order to perform S16.
S16: driving chip by the last frame data of previously received vedio data according to
Clock signal period exports and carries out brush screen to display floater and show.
It follows that the embodiment of the present invention is replicated by driving chip and periodically exports tableaux
Data, it is not necessary to processor is continual to driving chip output video image data, again by driving core
Sheet drives display floater, i.e. processor to need not continue through coffret and performs to export static picture
This digital signal action of face data, therefore, it is possible to reduce numeral power consumption stream such that it is able to reduce number
The word power consumption stream power consumption to display drive apparatus, reaches the purpose of power saving.
Referring again to Fig. 2, driving chip 22 includes crystal oscillator unit 221 and logic control element 222,
Crystal oscillator unit 221 is used for producing preceding clock signal, and logic control element 222 is according to clock signal
Periodically vedio data is exported to display floater, and control display floater 23 and brush
Screen display.In view of crystal oscillator unit 221 can produce clock signal according to predetermined crystal oscillator frequency automatically, because of
This is when vedio data is tableaux data, and the embodiment of the present invention can be considered by driving chip
22 automatically generate tableaux data to drive display floater 23 to carry out brush screen and show.Wherein, brilliant
The unit 221 that shakes can be quartz crystal oscillator or pottery crystal oscillator, is certainly not limited to this.
Fig. 3 is the structural representation of another embodiment of display drive method of the present invention.Such as Fig. 3 institute
Showing, the display drive method of the present embodiment includes following:
S31: processor produces and output video image data；
S32: judge whether vedio data is tableaux data；
If it is determined that vedio data is moving picture data, then perform S33 and S34；If it is determined that
Vedio data is tableaux data, then perform S35～37.
S33: processor is to driving chip output video image data；
The moving picture data received is exported by S34: driving chip according to clock signal period
Carry out brush screen to display floater to show；
S35: processor stops to driving chip output video image data；
S36: driving chip by the last frame data of previously received vedio data according to
Clock signal period exports and carries out brush screen to display floater and show；
S37: detecting whether to perform the scheduled operation to display floater, described scheduled operation includes making
Obtain processor to produce and the operation of output video image data, such as unlocked by fingerprint, touch display surface
Application icon, renewal on plate show the interrupt operations such as content；
If scheduled operation being detected, representing and needing display dynamically at this predetermined period display drive apparatus
Picture, then perform S33 and S34；If being not detected by scheduled operation, representing and showing at this predetermined period
Show that driving means still shows tableaux, then continue executing with S35 and S36.
Being with the difference of embodiment illustrated in fig. 1, the present embodiment is applicable to display drive apparatus
When having new image update, driving chip receives the data after updating so that display floater shows more
Image after Xin.
