Description

server system

The present invention relates to a servo system, and more particularly to a servo system that increases the efficiency of a tester during product development.

The basic properties of the servo system include host name, Internet Protocol (IP) address, and Media Access Control (MAC) address. If users want to obtain this information, they can log in to the operating system and enter the Intelligent Platform Management Interface (IPMI) command to query the Baseboard Management Controller (BMC) or access the machine through the remote servo system. The substrate management controller to obtain the relevant set values.

However, the above methods of operation are often complicated. In addition to having to spend a lot of time, the user must have some expertise in order to use many IPMI commands to complete the operating steps of the servo system. Moreover, this situation is more prominent in the product testing phase. The main reason is that when the servo system is still in the product testing phase, testers often continually modify the IP address, MAC address and other information. In contrast, testers must also continually 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 in FIG. 1, the conventional servo system 100 is provided with a microprocessor 120 between the substrate management controller 110 and the display panel 130. Thereby, the microprocessor 120 performs a series of processing and decoding on the data transmitted from the substrate management controller 121, and then controls the display panel 130. As a result, the conventional servo system 100 can simplify the instructions issued by the user to the substrate management controller 110, thereby reducing the time for the user to query the servo system.

However, in practical applications, the price of the microprocessor 120 is relatively high, so the manufacturing cost of the conventional servo system 100 will also be increased. In addition, in practice, the pins of the microprocessor 120 can only be defined for use in one or a few specific functions, so the user must write a complicated firmware to complete the microprocessor 120 on the display panel 130. control. In contrast, this situation will reduce the efficiency of testers in the product development and production phases.

The invention provides a servo system for increasing the working efficiency of testers in the product development stage and the production stage, and shortening the time to market of 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 configured to convert the serial display data into a side by side display data. After that, the display panel will directly 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.

In an embodiment of the invention, the panel controller 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 an embodiment of the invention, the panel controller receives the serial display data through an internal integrated circuit bus. In addition, the backlight control unit drives the backlight of the display panel when the display panel is not in the default state.

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 first connector are disposed on the substrate. In addition, the 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 type that the display panel can receive. In other words, the user can complete the control of the display panel of the panel controller without writing complicated firmware, thereby increasing the working efficiency of the tester in the product development stage and the production stage. 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 be more apparent from the following description.

FIG. 2 is a circuit diagram of a servo system according to an embodiment of the 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 face controller 220 and the backlight control unit 230 are coupled to the display panel 240.

In the overall operation, the substrate management controller 210 is configured to generate a series of display data D ₂₁ . Since the connectors 260 and 270 are electrically compatible with each other, the panel controller 220 can receive the serial display data D ₂₁ from the substrate management controller 210 through the connectors 260 and 270. Thereafter, the panel controller 220 converts the serial display data D ₂₁ into the side-by-side display data D 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 material D ₂₂ to the display panel 240 to cause the display panel 240 to display the data D _{22 in} parallel.

It should be noted that the servo system 200 can directly generate the serial display data D ₂₁ by the substrate management controller 210. Therefore, the panel controller 220 only needs to perform the serial-to-parallel data conversion to generate the data type that the display panel 240 can receive. In other words, the user can complete the control of the display panel 240 by the panel controller 220 without writing complicated firmware, thereby increasing the working efficiency of the tester in the product development stage and the production stage. In addition, since the panel controller 220 can control the display panel 240 without a large function, the circuit of the panel controller 220 is relatively simple, thereby contributing to reducing the manufacturing cost of the servo system 200.

Further, the panel controller 220 receives the serial display data D ₂₁ 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 S ₂₁ -S ₂₃ 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.

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 240 is in the default state, the backlight control unit 230 will not generate the backlight control signal S _BL to cause the display panel 240 to emit no light source. In contrast, when the user pops the display panel 240 such that the display panel 240 is not in the default state, the backlight control unit 230 generates a backlight control signal S _BL to thereby drive the backlight of the display panel 240. Furthermore, the backlight control unit 230 is further controlled by the panel controller 220. Under the control of the panel controller 220, the backlight control unit 230 will adjust the characteristic parameters (such as brightness and uniformity) of the backlight of the display panel 240, thereby improving the picture quality and color saturation of the display panel 240. .

In order to make the spirit of the embodiment more familiar to those skilled in the art, the internal structure of the backlight control unit 230 will be further described below.

FIG. 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 230 includes a switch SW _1, resistor R ₁ and R _2, level controller 310 and a P-type transistor TP _1. The first end of the switch SW ₁ is coupled to a ground voltage. The first end of the resistor R ₁ is coupled to a power supply voltage V _DD , and the second end thereof is coupled to the second end of the switch SW ₁ . The level controller 310 is coupled to the second end of the switch SW ₁ . The source of the P-type transistor TP ₁ is coupled to the power supply voltage V _DD , and the gate thereof is coupled to the level controller 310 . The first end of the resistor R ₂ is coupled to the drain of the P-type transistor TP ₁ , and the second end thereof is coupled to the display panel 240 .

In the overall operation, the switch SW ₁ determines whether to turn on the first end and the second end according to the state of the display panel 240. For example, when the display panel 240 is in the default state, the switch SW ₁ turns off its first end and second end. At this time, the level controller 310 receives the power supply voltage V _DD and accordingly generates a switching signal S _LV having a high potential. When the gate of the P-type transistor TP ₁ receives the switching signal S _LV having a high potential, it will be in an off state, and the power supply voltage V _DD will not be able to cross across the resistor R ₂ . In contrast, the resistor R ₂ will also be unable to generate the backlight control signal S _BL , thereby causing the display panel 240 to be unable to emit a light source.

On the other hand, when the display panel 240 is not in the default state, the switch SW ₁ turns on its first end and second end. At this time, the level controller 310 receives the ground voltage and accordingly generates a switching signal S _LV having a low potential. When the gate of the P-type transistor TP ₁ receives the switching signal S _LV having a low potential, it will be in a saturated state, and the power supply voltage V _DD will be across the resistor R ₂ . In contrast, the second end of the resistor R ₂ will generate a backlight control signal S _BL , which in turn drives the backlight of the display panel 240 .

In other words, under the control of the level controller 310, the P-type transistor TP ₁ will cause the resistor R ₂ to determine whether to generate the backlight control signal S _BL according to whether the switch SW ₁ is turned on or not. In contrast, the backlight of the display panel 240 will be driven according to the backlight control signal S _BL .

In summary, 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 type that the display panel can receive. In other words, the user can complete the panel controller's control of the display panel without writing complex firmware, thereby increasing the efficiency of the tester in the product development and production phases, and helping to reduce the manufacturing cost of the servo system. .

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.
