The embodiment of the present invention is illustrated so that a driving chip drives multigroup LED string simultaneously as an example, the driving chip
Plurality of display modes (being flashing mode) is built-in with, is filled in using embedded storage, code, the mode such as circuit editor, also may be used
So that with the integrated EEPROM of technique, (Electrically Erasable Programmable Read-Only Memory, electricity can
EPROM) etc. nonvolatile storage as medium, various flashing modes are burnt in driving chip, flash
Subjective effect mainly have but be not limited to gradually bright, gradually secretly, Chang Liang turns off the light, quick-fried to dodge etc., and every kind of flashing mode all corresponds to one
Persistent period, the corresponding one or more groups of LED strings of every kind of flashing mode.
The driving chip is self-defined to select to show mould according to plurality of display modes (being the control signal of flashing mode)
Formula so that the flashing mode of every group of LED string is all different.Every group of LED string all includes multiple LEDs, according to the display mould
Formula controls being switched on or off for the multiple switch pipe being connected with multiple LEDs, so that per group of LED string is shown
Show.
Used as one embodiment of the invention, in display sequence setup module 20, display sequence referred to provide according to the time
Display pattern and the corresponding logic switch combined sequence of its duration that sequencing expresses out so that circuit is suitable by this
Sequence completes particular task.Every group of LED string is according to display sequence so that every group of LED string is each according to sequencing in difference
Time in carry out action.Filled in using embedded storage, code, the mode such as circuit editor, it is also possible to it is integrated with technique
(Electrically Erasable Programmable Read-Only Memory, electric erazable programmable is read-only to be deposited EEPROM
Reservoir) etc. nonvolatile storage as medium, various flashing modes are burnt in driving chip (in fact, the later stage needs to change
What is become is display sequence, because display sequence really can realize the styles such as flowing water sudden strain of a muscle with very strange and general all very long
It is the difference and chip order in systems by display sequence).
As one embodiment of the invention, in drive module 30, by arranging display sequence to driving chip so that per group

Frequency is consistent.Identical frequency of oscillation is provided to every group of LED string so that every group of LED string realized with the effect of frequency homophase, can
Efficiently control the flicker of every group of LED string.
Below according to the flashing controlling method and system of LED string, to realizing the operation principle that multigroup LED crossfire water dodges
It is illustrated：
There are five driving chips connected with juxtaposition, mould is arranged by display pattern memory module 10 and display sequence
Block 20 coordinates, and makes expression to sudden strain of a muscle method sequence following a, b, c, d, the e of drive module 30, the LED string being processed into according to a, b, c,
The order arrangement of d, e is (it is assumed here that every driving chip controls three LEDs, respectively red, green, blue；“；" between the face write
Color is bright light color, and the color do not write is to turn off the light；" going out " printed words go out for three lamps etc. entirely)：
A) the built-in flashing mode of first driving chip is：It is red；Go out；Go out；Go out；Go out；Persistent period is 1 second；
B) the built-in flashing mode of second driving chip is：Go out；It is red；Go out；Go out；Go out；Persistent period is 1 second；
C) the built-in flashing mode of the 3rd driving chip is：Go out；Go out；It is red；Go out；Go out；Persistent period is 1 second；
D) the built-in flashing mode of the 4th driving chip is：Go out；Go out；Go out；It is red；Go out；Persistent period is 1 second；
E) the built-in flashing mode of the 5th driving chip is：Go out；Go out；Go out；Go out；It is red；Persistent period is 1 second.
When LED start of string works, when first second, first LED of first group of LED string is red light, remaining LED
String is turned off the light；
When second second, second LED of second group of LED string is red light, and remaining LED string is turned off the light；
When the 3rd second, the 3rd LED of the 3rd group of LED string is red light, and remaining LED string is turned off the light；
When the 4th second, the 4th LED of the 4th group of LED string is red light, and remaining LED string is turned off the light；
When the 5th second, the 5th LED of the 5th group of LED string is red light, and remaining LED string is turned off the light；
So as to form propulsion over time, every one second, red light was moved back by with the position of LED string and LED
Make a movement, realize the effect that multigroup LED crossfire water dodges.
In sum, the flashing controlling method and system of a kind of LED string are embodiments provided, including it is multigroup
LED string and at least one driving chip, multigroup LED string is connected with driving chip, and the flashing controlling method includes following step
Suddenly：Prestore plurality of display modes；Display sequence is arranged to driving chip；With reference to display sequence, every group of LED string is sequentially made
Shown according to the display pattern corresponding to it.Display sequence is combined from there through every group of LED string, and sequentially according to display
Pattern enters line flicker, realizes multigroup LED crossfire water sudden strain of a muscle, mobile sudden strain of a muscle or random sudden strain of a muscle and other effects, and its control method is simple
It is easy, thus solve the flicker control technology of existing LED string exist cannot allow multigroup LED string realize flowing water dodge,
The problem of the asynchronous styles such as mobile sudden strain of a muscle.
One of ordinary skill in the art will appreciate that：The step of realizing said method embodiment or part steps can pass through
Completing, aforesaid program can be stored in computer read/write memory medium the related hardware of programmed instruction, and the program exists
During execution, the step of including said method embodiment is performed, and aforesaid storage medium includes：ROM, RAM, magnetic disc or CD
Etc. it is various can be with the medium of store program codes.
