Specific implementation mode
The embodiment of the present application provides a kind of method for displaying image, as shown in Figure 1, this method includes：
S101, the line n pixel data of the line n pixel data of current frame image and the previous frame image of caching is carried out
Compare, determines whether the row pixel data changes；N is the integer more than 0 and less than or equal to N, and N is total number of lines of pixels；
If so, thening follow the steps S102；If it is not, thening follow the steps S103；

Method for displaying image provided by the embodiments of the present application passes through the pixel data and former frame figure to current frame image
The pixel data of picture is compared, and determines whether the pixel data of the line n pixel of current frame image changes, when the row pixel
Pixel data change and the number of current record be not less than preset times when, update is scanned to the row pixel, when
When the pixel data of the row pixel is less than preset times without the number of variation and current record, which is not scanned
Update；That is for each frame image, method for displaying image provided by the embodiments of the present application only needs to send out pixel data
The pixel column for changing or pixel column scanning of the number not less than preset times for working as secondary record update, and do not send out pixel data
Changing and when time record number be less than preset times pixel column without scanning update, i.e., when display picture need to update
When, it is scanned update without all pixels to entire picture, to reduce the power consumption for showing product when display frame updating.
It should be noted that for some display pictures in practical application, even if picture needs to update, nor per a line
The pixel data of pixel all changes, for example, showing that product, display frame updating only have the picture of numerical portion for meters
Prime number is according to needing to update；Product is shown for e-book class, when showing frame updating, only need to may update the specific of each chapters and sections
Word content, and illustration or title division are without update.Even if needing to refresh for picture, nor the pixel per one-row pixels
Data all change situation, using method for displaying image provided by the embodiments of the present application, can realize to needing to show picture
Face pixel data needs newer pixel column to be scanned update, and pixel data does not need newer pixel column without scanning
Update.When showing that product shows picture, it usually needs setting certain frequency refreshes display picture, such as when to display
Picture carries out 1 second 30 times refreshings, and the frequency of picture refreshing is 30Hz, when using image display side provided by the embodiments of the present application
The display picture of method is after repeatedly refreshing, and the frequency that different zones refresh in viewing area is different, and pixel data does not change
Region refreshing frequency be less than the changed region of pixel data refreshing frequency, i.e., do not change for pixel data
Its refreshing frequency of region be less than 30Hz, to can be reduced during show image update show product power consumption.
Even if it should be noted that the pixel data of certain one-row pixels present frame compared with the pixel data of former frame always
It remains unchanged, it is also desirable to it charges to the pixel after to the row pixel without a period of time of scanning, i.e. current record
Number need to be scanned update to the row pixel when being greater than or equal to preset times, to charge to the row pixel.
Pixel is not scanned, pixel is kept, different zones correspond to signal sequence such as Fig. 2 institutes of different refreshing frequencys
Show, 1 second f1 times refreshing is carried out to display picture, the refreshing frequency in the changed region of pixel data is f1, pixel data
It is f2 not have the refreshing frequency in changed region, wherein f1>F2, the t1 period charge to pixel, and the t2 periods protect
It holds, in 1/f2 seconds, the changed pixel column of pixel data has carried out multiple refresh and carried out multiple charging, and pixel number
