And when the latch signal u# is transmitted, the clock money GIC data temporary storage 24 must be suspended. The data buffer 24 includes 243, 245, 245 and 247, respectively connected to the corresponding displacement register 22 223, The output terminals of 225 and 227 and the signal lock wheel 211 are latched, and the data temporarily stored in the corresponding register registers 22, 225, 225 and 227 are latched according to the trigger of the latch signal LA#. In the normal display mode, when the LED driver module 28 is enabled, Lu will drive the corresponding LEDs 201, 203, 205 and 207 according to the data flashed by the data registers 241, 243, 245 and 247. . The control temporary storage module 26 includes a plurality of control registers 2 61, 263, 265 and 267 respectively connected to the outputs of the corresponding data registers 241, 243, 245 and 247 and the output of the signal detector 25. And outputting the data latched by the data buffers 241, 243, 245 and 247 corresponding to the trigger of the control trigger signal by the signal detector 25, and transmitting 6 M368163 to the LED driver module 28 respectively, according to The latched data adjusts the operation mode, function surface or characteristics of the LED driver module 28. The signal detector 25 is also coupled to the clock input 215 and receives the clock signal Clock as a reference for its output control trigger signal. When the system needs to adjust the LED driving module 28, a specific form of signal can be input to the latching signal input terminal 211, such as this creation to use two consecutive (or more than two) when the clock signal is stopped. Latch - Signals 32, 34 allow the signal detector to detect. . When the signal detector 25 detects the signal of the specific form, the control trigger signal is generated, so that the control registers 261, 263, 265 and 267 latch the corresponding data register 24 243, 245 and The information in 247 is also used as a control signal and transmitted to the LED driver module 28 for adjustment of the working mode, functional surface or characteristic. Among them, you can choose to adjust the LED's working mode, drive current, average brightness, white balance, etc., or after long-term use, depending on the aging state of each color LED. The control circuit 20 of the present invention can be used in series. In order to avoid signal attenuation, a buffer 295, 293 can be respectively disposed at the clock output terminal 216, the data control output terminal 214 and the latch lock signal output terminal 212. And 291. In this embodiment, the control circuit of four LEDs is taken as an example. When the number of LEDs of the module is changed, it is only necessary to increase or decrease the corresponding displacement register, data register and control register. Please refer to FIG. 4 and FIG. 5, which are circuit schematic diagrams and signal timing diagrams of another embodiment of the present invention. As shown in the figure, the configuration of the control circuit 7 of the present embodiment is substantially the same as that of the embodiment shown in FIG. 2. However, the control circuit 40 of the present embodiment includes only the data control input terminal 413 and the data control level output terminal 414. The data control signal Data/Control is received and transmitted; the time pulse input terminal 415 and the clock output terminal 416 are configured to receive and transmit the clock signal Clock. A latch signal generator 42 is provided in the control circuit 40 to connect to the clock input terminal 415. When the latch signal generator detects that the clock signal Clock stops and maintains a high level or a low level for a set time 58, a latch signal LA# is generated, thereby triggering each data register 241, 243, 245. The 247 latches the data corresponding to the displacement registers 221, 223, 225, and 227, and drives the corresponding LEDs 201, 203, 205, and 207 according to the latched data when the LED driver module 28 is enabled. The signal detector 25 is connected to the output of the latch signal generator 42. When the signal detector 25 detects a specific type of signal, for example, two or more latch signals 52, 54 generated by the clock signal Clock generate a control trigger signal, thereby triggering each control. The registers 261, 263, 265 and 267 latch the data in the corresponding data registers 241, 243, 245 and 247 and transmit them to the LED driver module 28 for adjustment. The above is only the embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications of the shapes, structures, features and spirits described in the scope of the patent application. It should be included in the scope of the patent application for this creation. [Simple description of the diagram] M368163 2 1 Figure · is a schematic diagram of a series of LED display modules.
