Description of the Invention: [Technical Field] The present invention relates to a driver and a control system using the same, in particular, a driver for an image or information and a point sequence control using the driver system. [Prior Art] Ο ^ In displays with high sinus requirements, such as LED traffic screens, the controller should collect the status detected by each drive to determine if the display is different. In an [ED__ display screen, as shown in Figure 1, a main controller 2〇〇 (the main two controllers may be by - a control element, in various layers such as hierarchy or mesh =, and, here, only Uncovering the part of each string of control components directly) Controls the D driver 'per-string (four) LED drivers to be dirty, :, = an integer greater than or equal to one. Taking the first string as an example, the information is output by the master 〇 ^ 0❸210-1埠, via the first LED driver ▲ C41 SDI淳! Passing through the serial data buffer is called general; the shift register) is then output via the sd◦埠 to the lower-level coffee 100C-12 ′ so that it can be passed in order to make an LED driver. In this design, if the function of error detection is required, each driver-independent state output 埠, the output signal is fed back to the main control, and the two drivers usually have multiple LED driver outputs (the figure does not show the pin-out of the factory). The state outputs are often connected in parallel to save the output of the main controller. 3 201042601 - kind =, =; US and profit announcement number drives σσ and its system, where the driver test 1 〇〇I !1 ^ 200 ^ ^ ^ makes -: Drive cry =?, [!

The cost, and 'doubled lines also increase the difficulty in construction and maintenance and timing design. [Declaration] The purpose of the present invention is to provide a drive with information reverse backhaul 4 201042601 • and the use of this drive Point ^ "The controller of its co-operation: the column control system, which can reduce the number of points that can be controlled by the controller = the demand of the ancient entrance and the buffer and increase the control of the driving of the invention -: guilty The device operates in conjunction with the controller: a second/one embodiment, the *including-type drive system can be based on a first control signal system, and can be integrated into a buffer according to the output of a second control signal controller.

The cycle is repeated to complete the operation of the drive. In the present invention, the preferred (f) driver reverse backhaul can be generated by the master controller 200 by a combination of signals that are not used. For example, after there is a pulse in the latch signal, do not send the CLK pulse and send the second pulse of the lactii signal, so that the REV signal of Figure 5 is reversed to make the transmission reverse. When the CLK pulse is not sent, the third continuous pulse of the LATCH signal can be used as the RpT signal in the enable picture. It has been decided that the reversed signal is the received signal or the detected status. When the continuous pulse of the LATCH signal ends, the CLK signal causes the shift register 11 to start moving data, and the LATCH pulse signal after the pulse of the clk can be used as a clear REv, RPT signal. The above is just an example. The system can use the unused signal combination to enable or disable reverse transmission. The REV signal is also used to change the input and output directions of the SDICU and SDI02. The data output of the main controller 2〇〇 is entered into Datap, and the input and output directions must also be changed accordingly. Figure 5A discloses a prior art data transfer path, such as a thick line. No, lean material is output via SDI〇1, multiplexer 160, shift register 110, and then SDI02.

The data of the shift temporary storage 110, that is, the data received from the main controller 200, is shifted by the SDI01 to the previous stage LED driver. The main controller 2 can be sequentially read by the sm〇1 of the LED driver 1第一 of the first stage to the data received by the previous lED 8 201042601 'driver to determine that the signal connection between the LED drivers is normal and the transmission is correct. If the detection state of each LED driver is reversely returned, the detection state can be stored by the RPT signal from PD-1 to PD-q to the return shift register 150. When the CLK sends a pulse, the detection state of the latter stage is transmitted along the SDIO1 of the next stage to the input of the SDI02 of the stage to the input of the transfer shift register 150 along with the synchronization signal of the CLK, and the back transfer already exists.
