Abstract
The invention discloses a method for realizing refreshing of different refresh rates by dividing display interfaces into regions, which comprises the following steps: calculating a control to be refreshed; calculating an area to be refreshed of a display interface; calculating the area affected by the refreshing; determining a final refresh area; refreshing the designated area; pasting the content of the refreshing area to the background area; and displaying the interface after partial refreshing on a screen. The display interface is composed of a plurality of display elements to achieve a display effect, and the display elements comprise a background area, display elements and a display area. When neither the display element nor the display area is displayed, the background area is completely displayed; when at least one of the display element and the display area is displayed, a part of the background area is occluded. The method can improve the refresh rate of the specific area of the display page, and simultaneously reduce the requirements on the calculation and the bandwidth of the image processing unit during interface refreshing; the method realizes better display effect and reduces the performance requirement on the image processing unit.
Description
Technical Field
The invention relates to the field of a display interface regional refreshing method, in particular to a method for realizing refreshing of different refreshing rates of a display interface regional.
Background
Human-Machine Interface (HMI) is a medium for transmission and interaction between users and machines, and virtual meters implemented based on liquid crystal screens tend to replace traditional mechanical meters.
The virtual instrument on the vehicle is used for displaying vehicle information such as vehicle number, mileage, alarm and the like and auxiliary driving information such as navigation and the like.
When the virtual instrument displays information, areas on the display interface continuously change when the information is displayed, such as vehicle speed, flashing alarm lamps and the like; and some areas are rarely changed when displaying information, such as mileage, oil amount, electric quantity and the like. When the number of pixels of the display interface is small (e.g., 480 × 272), the overhead such as calculation, bandwidth and the like of the image processing unit is relatively small during the whole screen refreshing, and when the number of pixels of the display interface is large (e.g., 1280 × 480), the overhead such as calculation, bandwidth and the like of the image processing unit is large during the whole screen refreshing.
Therefore, a method for realizing refreshing of different refresh rates in different regions of the display interface is proposed to solve the above problems.
Disclosure of Invention
The present invention provides a method for implementing refresh of different refresh rates in different regions of a display interface, so as to solve the problems proposed in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: a method for realizing refreshing of different refresh rates in display interface subareas comprises the following steps:
s1: calculating a control to be refreshed;
s2: calculating an area to be refreshed of a display interface;
s3: calculating the area affected by the refreshing;
s4: determining a final refresh area;
s5: refreshing the designated area;
s6: pasting the content of the refreshing area to the background area;
s7: and displaying the interface after partial refreshing on a screen.
Preferably, the display interface is composed of a plurality of display elements to realize a display effect, and the display elements include a background area, a display element, and a display area.
Preferably, when neither the display element nor the display area is displayed, the background area is fully displayed; when at least one of the display element and the display area is displayed, a part of the background area is occluded.
Preferably, the display element is a control, and displays information and data.
Preferably, the display area is a collection of a plurality of controls.
Compared with the prior art, the invention has the beneficial effects that: the method can improve the refresh rate of the specific area of the display page, and simultaneously reduce the requirements on the calculation and the bandwidth of the image processing unit during interface refreshing; the method realizes better display effect and reduces the performance requirement on the image processing unit.
Drawings
FIG. 1 is a schematic view of a partitioned refresh process according to the present invention;
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a method for realizing refreshing of different refresh rates in display interface subareas comprises the following steps:
s1: calculating a control to be refreshed;
s2: calculating an area to be refreshed of a display interface;
s3: calculating the area affected by the refreshing;
s4: determining a final refresh area;
s5: refreshing the designated area;
s6: pasting the content of the refreshing area to the background area;
s7: and displaying the interface after partial refreshing on a screen.
The display interface is composed of a plurality of display elements to achieve a display effect, and the display elements comprise a background area, display elements and a display area. When neither the display element nor the display area is displayed, the background area is completely displayed; when at least one of the display element and the display area is displayed, a part of the background area is occluded. The display element is a control used for displaying information or data in a specified form. The display area is a set of a plurality of controls, the display area is a control set of the same display area, and the update frequency of the displayed data of different display areas is different, so that the requirements on the refresh frequency of the controls are different, and the refresh rate of each display area may be different.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
