Abstract
The invention discloses a screen refreshing device and a method based on a syncretic communication terminal, belonging to the technical field of the structure of the screen refreshing device and the screen refreshing method which are based on the syncretic communication terminal and can improve the procedure response speed in the information or communication technology. The screen refreshing device comprises a GUI (graphic user interface) module, an LCD (liquid crystal display) screen refreshing module and an LCD drive module; through increasing the LCD screen refreshing module, the screen area needing to be refreshed is cut into a plurality of small rectangular areas, and the dot matrix data of the small areas are written into the LCD one by one through the LCD drive module at regular time. Since the screen area needing to be refreshed is cut into a plurality of small rectangular areas, the time for refreshing the small areas cannot influence the processing on other service modules, thus promoting the procedure response speed.
Description
Technical field
The present invention relates to a kind of brush screen device and method based on converged communication terminal; The technical field that belongs to the apparatus and method of the information or the communication technology belongs in the information or the communication technology structure and the technical field of brush screen method that can improve the brush screen device of program response speed based on converged communication terminal specifically.
Background technology
Along with the arrival in converged communication epoch, the transmission that enterprise can carry out information through converged communication terminal with exchange.Converged communication terminal will be responsible for handling communication protocol, voice and graphical interfaces and show.Wherein graphical interfaces shows and to be handled by special GUI module that (GUI is the abbreviation of Graphical User Interface-graphic user interface, claims that again graphical user interface is meant the computer operation user interface that adopts graphics mode to show.Compare with the Command Line Interface that early stage computing machine uses, graphical interfaces visually is easier to accept for the user; ), GUI module invokes shape library generates the graphical interfaces of rectangle, and the dot array data of graphical interfaces, writes LCD through the LCD driver, realizes the demonstration of graphical interfaces.But; When the dot array data that will write LCD is bigger; The GUI module can take CPU (central processing unit) for a long time; And other business module will can not get timely processing at this moment, the business module (such as speech processing module) that has real-time to require produced influence, thereby directly influence the response speed of whole procedure.
In order to address the above problem, common way is to change more high performance CPU to improve brush screen speed, need change hardware designs like this, causes hardware cost to increase, and the construction cycle prolongs greatly.
Summary of the invention
The invention provides a kind of brush screen device and method,, need not to change more high performance CPU, can guarantee the purpose of program response speed for will write bigger LCD dot array data the time to be implemented in during graphical interfaces shows based on converged communication terminal.
For reaching described purpose technical scheme of the present invention be:
A kind of brush screen device based on converged communication terminal is based upon on the basis of existing converged communication terminal, comprising: a GUI module, a LCD brush panel module and a LCD driver module;
Described GUI module as the request of a brush screen, is issued LCD brush panel module to the dot array data in graphical interfaces brush screen zone;
Described LCD brush panel module; With receiving that the inner brush of brush screen request adding to LCD brush panel module from the GUI module shields in the request queue; And after the trigger pip of receiving from operating system; Press first-in first-out and from the request queue of brush screen, take out the screen request of brushing, periodically in proper order dot array data is write successively the display buffer of LCD according to system clock singly by this brush screen request;
Described LCD driver module is called by this LCD brush panel module, writes the dot array data of LCD display buffer in the video memory;
This LCD brush panel module comprises interpolation module, Region Segmentation module and writes panel module;
Described interpolation module is in brush screen request adding to the brush screen request queue of receiving from the regional dot array data of the graphical interfaces brush screen of GUI module;
Described Region Segmentation module; After the trigger pip of receiving from operating system; Press first-in first-out and from the request queue of brush screen, take out the request of brush screen; Evenly cut apart lcd screen and become at least one rectangular area, the described rectangular area of contrast, the brush that will refresh screen zone is divided at least one rectangle zonule, and refreshes a required time of rectangular area and do not influence the processing of other business module;
The described panel module of writing, the display buffer of periodically asking to write the dot array data of these rectangle zonules successively in proper order singly LCD according to system clock by the brush screen.
This brush screen zone is less than the lcd screen zone; This rectangular area is less than described brush screen zone.
A kind of brush screen method based on converged communication terminal comprises the steps:
(300), the GUI module as the request of a brush screen, is issued LCD brush panel module to the dot array data in graphical interfaces brush screen zone;
(301), LCD brush panel module is with receiving that brush screen request adding to the LCD from the GUI module brushes in the inner brush screen request queue of panel module;
(302), LCD brush panel module is after the trigger pip of receiving from operating system; Press first-in first-out and from the request queue of brush screen, take out the request of brush screen; Evenly cut apart lcd screen and become at least one rectangular area; The described rectangular area of contrast, the brush that will refresh screen zone is divided at least one rectangle zonule, and refreshes a required time of rectangular area and do not influence the processing of other business module;
(303), LCD brush panel module periodically writes the LCD display buffer to the dot array data of these rectangle zonules through the LCD driver module singly in proper order according to system clock.
The described lcd screen of this step 302 zone is 160 * 96 lcd screen zone, and described lcd screen zone leveling is divided into the rectangular area of 6 54 * 48 sizes.
A described rectangular area of the said system clock periodic refreshing of this step 303 required time is less than 10ms.
The said brush of this step 300 shields the rectangular shape that is shaped as of regional structure.
Adopt brush screen device provided by the invention and method,, replace GUI resume module brush screen through increasing a LCD brush panel module; The GUI module as the request of a brush screen, is issued LCD brush panel module to the dot array data of graphical interfaces; LCD brush panel module is with receiving that brush screen request adding to the LCD from the GUI module brushes in the inner brush screen request queue of panel module; LCD brush panel module is after the trigger pip of receiving from operating system; Press first-in first-out and from the request queue of brush screen, take out the request of brush screen; And be divided into a plurality of rectangles zonule to the screen area that will refresh (brush screen zone), regularly write LCD to the dot array data of these zonules through the LCD driver module singly.
Because the screen area that will refresh (brush screen zone) is divided into a plurality of (rectangle) zonule; Can not influence the processing of other business module and refresh the required time of zonule; And be regularly to carry out,, can not influence other business module so whole brush screen process can not take CPU for a long time; The processing of the business module of real-time requirement is particularly arranged, thereby improved the response speed of program.
