Specific embodiment
Embodiments of the present invention are illustrated below by way of specific instantiation, those skilled in the art can be by this specification
Disclosed content understands other advantages of the invention and effect easily.The present invention can also be by specific realities different in addition
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints with application, without departing from
Various modifications or alterations are carried out under spirit of the invention.It should be noted that, in the case where not conflicting, the embodiment in the application
And the feature in embodiment can be mutually combined.
Reference picture 1, Fig. 1 depicts the schematic flow sheet of the method for refreshing of the display screen of one embodiment of the present invention.
First, in step s 110, central processing unit sends real time data to displaying screen controller.
Then, in the step s 120, displaying screen controller receiving real-time data.
Afterwards, in step s 130, displaying screen controller storage real time data, here, real time data is stored in display
In the buffer area of screen controller.
Then, in step S140, displaying screen controller compares real time data with pre-stored data to produce comparison result, this
In, pre-stored data is stored in advance in the buffer area of displaying screen controller, after real time data is also stored into buffer area, then
Both can be compared, and then produce a comparison result.
Then, in step S150, displaying screen controller determines whether to update according to comparison result, is tied by comparing
Really, it is to be understood that whether variant between real time data and pre-stored data, so as to can determine whether renewal, when real time data with prestore
When variant between data, then understand there is renewal, then into step S160, conversely, not updating then, be back to step S120, no
Display screen is refreshed.
In step S160, when there is renewal, displaying screen controller calculates minimum refresh region.
In one embodiment, minimum refresh region, can be the minimum enclosed rectangle region for updating content, here " interior
Hold ", refer to the arbitrary content that display screen can show, such as image, symbol, correspondingly, " more new content " can refer to any
The display content of renewal, carefully states on minimum enclosed rectangle region, can refer to following.
Reference picture 2, Fig. 2 depicts the schematic diagram of the minimum refresh region of the more new content of a specific embodiment.
As shown in Fig. 2 more new content is polygon A, its corresponding minimum refresh region is the minimum external square of polygon A
Shape region, i.e. the frame S of periphery, specifically, minimum enclosed rectangle refers to some two-dimensional shapes (examples represented with two-dimensional coordinate
Such as point, straight line, polygon) maximum magnitude, i.e., with maximum abscissa, the minimum horizontal seat in each summit of two-dimensional shapes for giving
Mark, maximum ordinate, minimum ordinate fix the rectangle on border.
Afterwards, in step S170, displaying screen controller refreshes to the minimum refresh region of display screen, so, shows
Display screen controller only need to be by the corresponding data is activation in minimum refresh region to display screen, to refresh the minimum flush zone of display screen
Domain.
In the present embodiment, due to need to only be refreshed the minimum refresh region corresponding to more new content, so that can
To improve efficiency, can be with power saving.
Fig. 3 is referred again to, Fig. 3 depicts the structural representation of the updating system of the display screen of another embodiment of the present invention
Figure.
As shown in figure 3, the updating system 300 of display screen includes central processing unit 310, displaying screen controller 320 and display
Screen 330.
As shown in figure 3, displaying screen controller 320 includes receiver module 321, memory module 322, comparing module 323, judgement
Module 324, computing module 325 and refresh module 326.
Receiver module 321, is used to receive the real time data of the transmission of central processing unit 310.
Memory module 322, is used to store real time data and storage pre-stored data, here, real time data and the pre- poke of storage
According to the buffer area that can be all stored in memory module 322.
Comparing module 323, is used to compare real time data with pre-stored data to produce comparison result.
Judge module 324, to be determined whether to update according to comparison result, according to comparison result, it is known that real time data
It is whether variant with pre-stored data, if variant, then it represents that there is renewal, otherwise, it means that not updating.
Computing module 325, when there is renewal, then computing module 325 calculates minimum refresh region, here, minimum flush zone
Domain can be the minimum enclosed rectangle region for updating content, and the calculation on minimum refresh region can refer to foregoing.
Refresh module 326, is used to refresh the minimum refresh region of display screen, i.e. only need to be by minimum refresh region
Corresponding data is activation to display screen 330, to refresh the minimum refresh region of display screen 330.
To sum up, the method for refreshing of display screen proposed by the invention, system and displaying screen controller, due to will need to only update
Minimum refresh region corresponding to content is refreshed, such that it is able to improve efficiency, can be with power saving.
Above, specific embodiment of the invention is described with reference to the accompanying drawings.But, those skilled in the art
It is understood that without departing from the spirit and scope of the present invention, can also make each to specific embodiment of the invention
Plant change and replace.These changes and replacement all fall in claims of the present invention limited range.
