Description of the invention: [Technical field of the invention] The present invention relates to a drive device for returning the status of the state -1^, and particularly has ~ The drive unit of the Bessie display. [Prior technology] The product is a common product; the display is a very common electronic product performance, in the display of the electricity: the display of the display on the product is not too early to open the road, = to enable the controller to adjust the device The controller 'branches, the drivers provided by the drive units of the body, and the 'is 5', are used to adjust the performance of the drive. Explicit-f dipole? The display device is used as an example. Because of the relationship between the display scales and the '', the unsatisfactory upper ten has a considerable number of right-handers that allow the controller to receive all the Congruo early A-changes. The detected status information is miscellaneous. On the other hand, these drive units may require a long transmission guide in order to finally control the ''then' control. The edge W is like the driver-level unit of the money-level. In addition to the poor transmission quality of the status information, the production line takes up a large wiring area and increases the cost of J! πα. 201234073 ΙΤΡΤ-10-009 36778twf The present invention provides a driving device for displaying a data signal according to a coupling sequence of a plurality of driving units therein or receiving state information of each driving unit in reverse. The present invention provides a display. The driving device comprises a controller and a plurality of driving units, wherein the controller transmits the data signals according to the transmission interface, and the plurality of driving units are used to drive the plurality of display lines of the display. The serial serial connection is connected, and the driving unit of the first stage is directly connected to the transmission interface of the controller. Each driving unit detects the status information of each display line of the corresponding driving, and each driving unit receives and determines that the data signal is a return command. When the transmission unit performs the backhaul operation, the transmission unit is coupled to each of the driving units and the controller by performing a backhaul operation to transmit the status information to the controller. The driving unit between the two transmits the status information to the controller. When the driving unit is directly connected to the controller, the driving unit directly transmits the status information to the controller. In one embodiment of the present invention, the driving unit of the first stage is directly The control command is received by the control n, and the other driving units receive the control command through the driving unit connected between the driving unit and the controller. Based on the above, the present invention proposes a multi-stage serially connected driving unit, and drives through each stage.

So - drive, t controller does not need to increase the state information in order to transmit status information, effectively simplify the wiring between the controller and the drive unit Complex 201234073 ITPT-10-009 36778twf.d〇c/n degrees 'and reduce the cost of the circuit. In order to make the above features and advantages of the present invention more obvious and easy to understand, the following specific examples, and with the accompanying drawings DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [FIG. 1] FIG. 1 is a schematic diagram of a driving device 100 for a display according to an embodiment of the present invention. The driving device 1A includes a controller and a plurality of driving units 121. 〜12N, where N is a positive integer greater than 1. The controller 110 transmits and receives data signals between the drive units 12ι and 12v by a transmission interface. The data signal includes display data DDATA transmitted to the drive units 121 to 12A and status information SINF returned by the drive units 121 to 12A. The drive units 121 to 12 are sequentially connected in series to drive the plurality of display lines 151 to 15 of the display screen 150 on the display 100, respectively. The driving unit 121 of the first stage is directly connected to the transmission interface of the controller 11A to receive the display data DDATA to which the controller 110 passes. In addition, the driving unit ® 121 can also transmit the status information detected by the driving unit 121 through a transmission interface directly connected to the controller 110. The above-mentioned status information refers to the fact that the dinghy moves early 121 ^[ 贞 其 其 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应 对应Here, the so-called state refers to at least one of the state of the open or short of the display line 151 and the temperature state (whether or not) of the display line 151. Further, the drive units Π2 to ΠΝ drive the display lines 152 to 15N in sequence. The drive units 122 to 12N also perform status information detection on the display of the display 201234073 ITPT-10-009 36778twf.doc/n line 152~15. The status information obtained by the driving units 122 to 丨2Ν is transmitted back through the connection interface of each of the driving units 丨2 2 to 丨2 ^ to the direction of the controller 110, so that all the driving units 121 to 12 are obtained. The status information can be transmitted back to the controller u by the controller u to connect the transmission interface of the driving unit 121. Specifically, the driving unit 12N is taken as an example. When the driving unit=12N performs the above-mentioned backhaul operation, the detected state information is transmitted through the driving unit 12N and the driving unit. 12 (N-1) to 121, the status information is sequentially transmitted to the controller 11A. Of course, at the same time, the driving unit ^ (ND~121 will also synchronously transmit the status information obtained by the four measurements to the controller 11 〇. In addition, the controller 110 also transmits through the connected transmission interface. The display data DDATA to be displayed for each of the display lines 151 to 15N is transmitted to each of the drive units 21 to 12N. Here, the display data DDATA transfer is performed for the display order of the display lines (5) to 15N. For example, It is explained that the display data DDATA of the line 15N to be received by the drive unit το 12N is transmitted first, and the display data DDATA of the line 151 to be driven by the opposite drive unit ΐ2 is transmitted at the latest. Since the transmission interface of the controller 110 cannot simultaneously transmit and receive at the same time, the controller UG can be configured to transmit or receive a dragon signal in its transmission interface. In this example, 'Control H 110 can still transmit command data to each drive unit 121~12N through the transmission interface. That is to say, the controller no is carrying out 201234073 ΙΤΡΤ-10-009 36778twf.doc/n
