(2), rgb interface mode: display data be not written into DDRAM, Direct Screen Writing, speed is fast, be usually used in show video or
Animation is used.
Because of the characteristics of rgb interface screen, if to maintain to show, the rgb interface of main control chip must constantly export aobvious
For registration according to display driver chip is given, display screen could maintain picture to show；In the case where UI picture does not change, also to maintain to connect
Confession electricity and I/O operation, can compare power consumption, research and develop the present invention is based on this power consumption problem.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of method of rgb interface LCD display province power consumption and is
System.
To achieve the above object, the specific technical solution of the present invention is as follows:
A kind of method that rgb interface LCD display saves power consumption, comprising steps of
S1: it is unchanged to detect UI picture within a preset time, and when no touch event, display driver chip is switched to
MCU interface modes show last picture using driving chip video memory；
S2: closing the display controller of main control chip, closes the rgb interface of main control chip, stops display Refresh Data.
Further include upon step s 2 step S3 as one optimal technical scheme of the present invention:
Continue to test whether UI picture changes, if changing, or UI picture is unchanged and has touch event to be walked
The inverse operation of rapid S2.
As an optimal technical scheme of the invention, the unconverted method of UI picture is detected within a preset time in step S1
Are as follows:
It counts, whether picture changes within the scope of count threshold.
The present invention also provides the system that a kind of rgb interface LCD display saves power consumption, which includes: main control chip, display
Driving chip, LCD display, the main control chip 101 include UI picture detection unit and touch control detection unit；
The main control chip obtains the UI image information of UI picture detection unit feedback, obtains touch control detection unit feedback
Touch event；
Detection UI picture is unchanged within a preset time, and when no touch event, main control chip cuts display driver chip
MCU interface modes are shifted to, last picture is shown using display driver chip video memory；Close the display control of main control chip
Device closes the rgb interface of main control chip, stops display Refresh Data.
As an optimal technical scheme of the invention, the main control chip continues to test whether UI picture changes, if there is change
Change or UI picture is unchanged and has touch event then to carry out opening the display controller of main control chip, opens the RGB of main control chip
Interface opens display Refresh Data.
Using technical solution of the present invention, have the advantages that
The present invention closes the rgb interface of main control chip, and display chip is switched to when detecting the no update of UI picture
MCU mode shows tableaux by the video memory content in display driver chip；When detecting that touch operation or UI update
When, the rgb interface of reactivation main control chip, refresh picture, has achieved the effect that save power consumption again.
Detailed description of the invention

Fig. 2 is the working principle of the invention figure；
Fig. 3 is the functional block diagram of present system.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to figs. 1 to shown in Fig. 2, the present invention provides a kind of method that rgb interface LCD display saves power consumption, comprising steps of
S1: it is unchanged to detect UI picture within a preset time, and when no touch event, display driver chip is switched to
MCU interface modes show last picture using driving chip video memory.
Specifically comprising following steps:
S101: whether detection UI picture changes, if so, returning to beginning state；If it is not, then entering step S102；
S102: whether detection touch screen has operation, if so, returning to beginning state；If it is not, then entering step S103；
S103: counting, and whether picture changes within the scope of count threshold, if so, returning to beginning state；If it is not, then into
Enter step S104；
S104: display driver chip is switched to MCU mode；
S105: final picture is shown using display driver chip video memory.
S2: closing the display controller of main control chip, closes the rgb interface of main control chip, stops display Refresh Data.
S3: continuing to test whether UI picture changes, if changing, or UI picture is unchanged and has touch event to carry out
The inverse operation of step S2.
Specifically comprising following steps:
S301: whether detection UI picture changes, if so, entering step S303；If it is not, then entering step S302；
S302: whether detection touch screen has operation, if so, entering step S303；If it is not, then entering step the subsequent of S2
Continuous step S301；
S303: opening the display controller of main control chip, opens the rgb interface of main control chip, opens display Refresh Data.
In S303 step and then step S101 is returned to, continues cycling through detection.
The present invention also provides a kind of rgb interface LCD display save power consumption system, the system include: main control chip 101,
Display driver chip 102, LCD display 103, the main control chip 101 include UI picture detection unit 1011 and touch control detection
