If the user wants to obtain this information, he can log in to the operating system locally and input the smart platform management interface (MP) command to query the BaseBardard Management Controller (BMC) or through the remote servo system. Access the baseboard management controller of this unit to obtain the relevant set values. However, the above methods of operation are often complicated. In addition to the time that the user must spend a lot of time, the user must have some expertise to use the many IPMI commands to complete the servo system's operating procedures. Furthermore, 此种 this situation is more prominent in the product testing phase. The main reason is that when the feeding system is still in the product testing stage, the testers often continually modify the IP address, MAC address and other information. In contrast, testers must constantly repeat the above methods to see the results of each verification. In other words, the tester must spend a lot of time to complete the test of the servo system. In order to solve the above problem, as shown by the circle i, the conventional servo system 1 is disposed between the substrate management controller 110 and the display panel 130, and is configured with a 5 200935299. ^ This microprocessor 12G performs a series of processing and decoding on the data transmitted by the substrate management controller, and then controls the display panel 130. In this way, the conventional feeding system will simplify the user's age for the 11G of the substrate tube, and (4) reduce the time for the user to query the servo system. However, in practical applications, the price of the microprocessor 12 is too high, so the manufacturing cost of the conventional & system 100 will also be increased. In addition, in the actual operation, the micro-processing H 120 pins can only be defined in a certain one or a few specific Wei to make it a complicated entity to complete the microprocessor 120 pairs. The display panel 13 is controlled. In contrast, this situation will reduce the efficiency of testers in the product development and production phases. SUMMARY OF THE INVENTION The present invention provides a servo system for increasing the efficiency of testers in the product development and production phases, and shortening the time to market for the servo system. The invention provides a servo system comprising a substrate management controller, a panel controller, a display panel and a backlight control unit. The substrate management controller is configured to generate a serial display data. The panel controller is used to convert the serial display data into a side by side display data. After that, the display panel will display the data in parallel. On the other hand, the backlight control unit is configured to detect whether the display panel is in a default state to determine whether to drive the backlight of the display panel according to the detection result. 6 200935299 In one embodiment of the present invention, the panel controller described above is further configured to generate a plurality of control signals to enable, reset, and read and write the display panel. In addition, the display panel is a character type display panel. In one embodiment of the invention, the panel controller described above receives the serial display data through an internal integrated circuit bus. In addition, when the display panel is not in the default state, the backlight control unit drives the backlight of the display panel. In an embodiment of the invention, the servo system further includes a substrate, a first connector, and a second connector. The substrate management controller and the connector are disposed on the substrate. Additionally, a first connector is coupled to the substrate management controller, and the second connector and the first connector are electrically compatible with each other' and coupled to the panel controller. The present invention utilizes a substrate management controller to generate a series of display data such that the panel controller only needs to perform serial-to-parallel data conversion to generate a data pattern that can be received by the display panel. In other words, the panel controller can control the display panel without the need to write complicated firmware, thereby increasing the efficiency of the tester in the product development and production phases. In addition, the circuit of the panel controller is relatively simple, which helps to reduce the manufacturing cost of the servo system. The above described features and advantages of the present invention will become more apparent from the following description. [Embodiment] FIG. 2 is a diagram showing a circuit frame 7 200935299 of a servo system according to an embodiment of the present invention. Referring to FIG. 2, the servo system 200 includes a substrate management controller 210, a panel controller 220, a backlight control unit 230, a display panel 240, a substrate 250, and connectors 260 and 270. The substrate management controller 210 and the connector 260 are disposed on the substrate 250, and the connector 260 is coupled to the substrate management controller 210. Further, the connector 270 is coupled to the panel controller 220. The panel controller 220 and the backlight control unit 230 are coupled to the display panel 240. The substrate management controller 210 is configured to generate a serial display data DZ1. Since the connectors 260 and 270 are electrically compatible with each other, the panel controller 220 can receive the serial display data D21 from the substrate management controller 210 through the connectors 260 and 270. Thereafter, the panel controller 220 converts the serial display data d21 into the side-by-side display data 22, that is, directly converts the material from the substrate management controller 210 from the serial form into a side-by-side format. Thereafter, the panel controller 220 transmits the parallel display data Da to the display panel 240' to cause the display panel 240 to display the data D22 in parallel. It is important to note that the server system 2 can directly generate serial display data by the baseboard management controller 210. Therefore, the panel controller 220 only needs to perform the serial-to-parallel data conversion to generate the data type of the display panel 24 . In other words, the user does not need to write a complicated firmware to control the display panel 240 by the panel controller 220, thereby increasing the efficiency of the tester in the product development phase and the production phase. In addition, since the panel controller 220 can control the display panel 240 without requiring a large function, the circuit of the panel controller 22 is relatively simple, which in turn helps the 200935299 to reduce the manufacturing cost of the servo system 200. Further, the panel controller 220 receives the serial display data through an Inter-Integrated Circuit Bus (I2C Bus) 280. In addition, the panel controller 220 is further configured to generate a plurality of control signals SZi to Sr' to enable, reset, and read and write the display panel 240. Moreover, in this embodiment, the substrate 250 can be a printed circuit board, and the display panel 240 can be a character type display panel. ❹ On the other hand, the backlight control unit 230 detects whether the display panel 240 is in a default state to determine whether to drive the backlight of the display panel 240 according to the detection result. For example, when the display panel 24 is in the default state, the backlight control unit 230 will not generate a backlight control signal, so that the display panel 240 cannot emit a light source. In contrast, when the user pops out the display panel 240 such that the display panel 24 is not in the default state, the backlight control unit 230 generates a backlight control signal Sb1 to thereby drive the backlight of the display panel 240. Furthermore, the backlight control unit 23 is further controlled by the panel controller 220. Under the control of the panel controller 220, the back light control unit 70 230 will adjust the display panel 240 "the characteristics of the backlight (such as brightness and uniformity), thereby improving the quality of the display panel 24 Color saturation and other properties. In order to make the spirit of the embodiment more familiar to those skilled in the art, the internal architecture of the backlight control unit 230 will be further explained. 3 is a circuit diagram of a backlight control unit according to an embodiment of the invention. Referring to Fig. 3, the backlight control unit 23A includes switching resistors K and R2, a level controller 31A, and a p-type transistor. In the basin, the first end of 9 200935299 is coupled to the - ground voltage. The first end of the resistor R1 - Chengyuan Wei Vdd' and its third end is input to the first of the switch SW1. The controller 310_ is to the second end of the switch SWi. The p-type electric two-source source-domain to the power supply voltage Vdd ' and its gate is lightly connected to the standard ^ 1 〇. The first end of the resistor R2 is coupled to the pole of the p-type transistor, and the second end thereof is coupled to the display panel 240. , the overall operation of the switch SWi will depend on the state of the display panel ❹ ft:: no conduction of its first end and second end. For example, when the display surface ^ is in the default state, the switch SW1 will turn off (tumQff) its first end and second end. At this time, the level controller 310 receives the power supply voltage Vdd' and accordingly generates a switching signal ^ having a high potential. When the gate of the p-type transistor TP) receives the switching signal Slv having a high potential, it will be in an off state, and the power supply voltage Vdd will not be able to cross over the resistor & In contrast, the resistor R2 will also be unable to generate the f-light (four) signal Sb1, thereby causing the display panel 240 to be unable to emit light. On the other hand, when the display panel 240 is not in the default state, the opening and closing SWi will turn on (t·on) its first end and second end. At this time, the level controller 310 receives the ground voltage 'and generates a switching signal sLV having a low potential accordingly. When the gate of the p-type transistor 接收ι receives the switching signal SLV having a low potential, it will be in a saturated state, and the power supply voltage = across the resistor & In contrast, the second end of the resistor & will be generated as the light control signal sBL, thereby driving the backlight of the display panel 24〇, in other words, the p-type electro-crystal Zhao TPl under the control of the level control 2, which will cause the resistor R2 determines whether the backlight control signal SBL is generated according to whether the switch SWi is turned on or not. The backlight of display panel 240 will be driven in accordance with backlight control signal SBL. In summary, the present invention utilizes a substrate management controller to generate an application display data such that the panel controller only needs to perform a serial-to-parallel data conversion to generate a data pattern that can be received by the display panel. In other words, the user can complete the panel controller's control of the display panel without writing complicated Boeing, thereby increasing the tester's work efficiency in the product development phase and the production phase φ and helping to reduce the servo system production. cost. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a circuit diagram of a conventional servo system.
