Description of the Invention: [Technical Field] The present invention relates to a driving device for a light emitting diode, and more particularly to a function of a driving device and a state of light emitting device Drive unit and its data transfer unit. [Prior Art] Light Emitting Diode (LED) is small, power-saving and durable, and as the process matures, the price drops. Recently, products using a light-emitting body as a light source have become more and more popular. In addition, the hairpin _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, light-emitting diodes are widely used in various terminal devices, ranging from automotive headlights, traffic lights, text displays, billboards and large-screen video displays, to general and architectural lighting and LCD backlights. Nowadays, in addition to the basic functions of driving the LED, in order to simplify the maintenance work of the overall system, the driving device of the LED is more suitable for detecting the state of the side drive device, and the system is returned to the system. Control circuit. ® 1 is the circuit architecture of the crane device of the traditional light-emitting diode. Please refer to the figure, the drive device coffee includes a shift register register 110, the image data register plus 匕reglSter) l2〇, the drive enable circuit u〇, the drive circuit _, the drive device detection circuit 150' extension The memory 16G, the _ current setting circuit 17 〇 201105171 iU81tWt.d 〇 c / n and the mode conversion circuit 180. A shift register 110 receives the timing signal CKI and the data input signal DIN, wherein the data input signal can be image data or a drive state. The shift register 11 cooperates with the timing signal CKI to retrieve the data input signal DIN, and outputs the extracted data input signal DIN to the image data register 12A. The shift register no output data output signal DO is used to transmit the image data or drive device status it receives to the next drive or external device. The image data register 120 determines whether to store the data from the shift register 110 based on the latch signal LAT. The drive enable circuit 13 receives the output enable signal EN' and controls whether the data stored in the image data buffer 120 is transmitted to the drive circuit 14A according to the output enable signal EN. The driving circuit H0 outputs a plurality of driving currents to the corresponding light-emitting diodes (not (4)) according to the data stored in the image data temporary storage H 12 , to drive the light-emitting diodes to emit light (not shown). The drive current setting circuit 17 is lightly connected to the drive circuit to set the magnitude of the drive current output from the drive circuit 140. In the non-display mode, the extension register 16 〇 can store the drive state of the drive=circuit W, and according to the division = will extend the temporary storage H (10) to practice the j device 110, wherein the trigger signal is driven by the mode The conversion circuit m produces = bit = the memory conversion circuit 180 receives the latch signal Lat and the output enables the pull type data to lock the money channel and (4) the money transfer EN input '. For example: during the period, the lock signal lat first: the trigger signal = the turn-off enable signal EN appears - the second pulse, then drive two: from the Μ mode to the non-display mode; otherwise, if the turn-out enable Tolerance 1: 201105171 31181twf.doc/n = The second pulse of the temple after the pulse is not generated, the drive device 100 switches from the non-display mode to the display mode. Since the conventional driving device can only state the state of the device, and the detection result of the driving device state needs to be stored until the extended temporary crying. In the '^ mode, triggered by the - trigger signal, the extension of the register lake can transfer the stored data to the shift temporary storage H丨 (10). The traditional method requires additional delay (four) memory · _ outside _ send money And the device has to be switched to the non-display, and the difficulty of the cost and the waste of the cost. [Invention] The present invention provides a driving device for a light-emitting diode and a data transmission unit thereof, which can directly detect the signal according to the path selection signal Saving to the data transfer unit 'and transmitting the gambling number directly to the external or next drive device through the data transfer unit can save the cost of installing the additional register.
