[0027] In order to solve the problem of inconvenience in displaying the type of device installed in the server due to the use of silk screen to display the type of device plugged into the card slot, the present application provides the following embodiments.

[0028] In some embodiments, Figure 1 As shown, an electronic device includes: The panel 100 is provided with at least one external device slot 110, and any one of the at least one external device slot is used to connect an external device; The display device 200 is arranged on the outer surface of the panel 100, and the display device includes at least one display area 210, and the at least one display area corresponds to the position distribution of at least one external device slot 110, and is used to display the device information of the external device connected to the corresponding external device slot.

[0029] The electronic device shown in this application refers to a personal computer, server, etc. whose chassis panel is configured with a display device, and a computer that can carry external devices.

[0030] An external device refers to a device connected to a computer motherboard through a slot. Schematically, an external device can be a display card, a disk, a network card, etc., which are connected to a computer through a PCIe interface.

[0031] Preferably, the external device slot is a PCIe slot.

[0032] The display device may be a liquid crystal screen. When the display device displays, at least one display area is presented. At least one display area displays the external device type code corresponding to the physical position of the external device slot. For an external device slot that is not connected to an external device, when the display device is used for display, it may be marked with "NC".

[0033] Preferably, the display device is an ink screen.

[0034] E-Ink Display or E Ink Screen is a special display technology named because its display effect is similar to the text and images printed on traditional paper. E-Ink screen is widely used in electronic readers, smart watches, electronic tags and other devices. Its main features are low power consumption, high visibility and eye-friendly. Working principle of E-Ink screen: Adopting microcapsule structure: The core technology of E-Ink screen lies in its unique microcapsule structure. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a transparent liquid. When voltage is applied, the particles move to the surface of the microcapsule according to the charge properties, thereby changing the color. Adopting electrophoretic display technology: E-Ink screen uses electrophoretic display technology to control the movement of particles by changing the direction of the electric field, thereby achieving black and white or color display. Adopting reflective display: E-Ink screen does not require a backlight source and relies on ambient light reflection to display content, so it is still clearly readable in bright environments and has extremely low power consumption. The technical features of E-Ink screen include: low power consumption, only consuming power when the screen content is updated, and no power consumption when displaying static content, so it is very suitable for long-term reading. High visibility: Due to the reflective display technology, the ink screen is still clearly visible under strong outdoor light, and the reading experience is close to that of paper books. Eye protection: Unlike LCD or OLED screens that emit blue light, the ink screen puts less burden on the eyes and is not easy to get tired after long-term reading. Flexibility: The new ink screen technology can achieve flexible display, allowing the screen to bend or fold, increasing the flexibility of device design. Resolution: With the advancement of technology, the resolution of the ink screen continues to improve, and it can support high-definition display, with more delicate text and images. Color display: In addition to traditional black and white display, modern ink screen technology also supports color display, which is achieved by adding color filters or other technical means. Ink screen technology will further improve resolution, response speed and color performance, while realizing more innovative applications through flexible display technology. In addition, with the development of the Internet of Things and smart cities, ink screens will also play a greater role in information display and interaction.

[0035] Figure 2 The front view of an electronic device is shown, and the display device 200 is arranged in the left area of ​​the panel 100.

[0036] Figure 3 The front view of another electronic device is shown, in which the display device 200 is arranged in the middle area of ​​the panel 100 .

[0037] Figure 4 A display mode of a display device 200 is shown, wherein the display area 210 corresponds to the position of the external device slot 110. For the linearly arranged external device slots 110, the display area 210 of the display device 200 is correspondingly arranged linearly.

[0038] The embodiment of the present application provides the advantage that the information on the display can still be displayed after the ink screen is powered off. Any configuration can flexibly display the silk screen and can display the detailed model of the device, such as Figure 4 The i350 network card and 2080Ti GPU in the example do not need to customize the chassis logo or silk screen sticker for each shipping configuration, which realizes the unbinding of the hardware space distribution configuration logo and the firmware asset information display, saving the manpower investment in firmware development and adaptation; it truly achieves the complete universality of a server machine, and even if the customer reconfigures it later, it can still display the information of the replaced or newly added PCIe device normally, assign a new silk screen name, and dynamically update the display of the device type and model. It solves the problem of general chassis silk screen fixed, unable to change randomly, and not user-friendly, adapts to the large number of server customization customers, realizes the customized adaptive change of chassis silk screen information, and improves the randomness and user-friendliness of chassis silk screen.

[0039] like Figure 5 As shown, the electronic device also includes: The driving module 300 is connected to the display device 200 and is used to provide a grayscale voltage for any pixel in the display device; The display control module 400 is connected to the display device 200 and is used to control any pixel in the display device to receive a grayscale voltage corresponding to the pixel according to display information, wherein the display information includes device information corresponding to any display area in at least one display area.

[0040] like Figure 1 As shown, the electronic device also includes: The main board 500 is provided with a driving module and a display control module; The connector 600 is disposed on the mainboard 500 and transmits the grayscale voltage provided by the driving module and the pixel selection signal provided by the display control module to the display device through the flat cable, wherein the pixel selection signal is used to select the pixel receiving the grayscale voltage in the display device.

[0041] The gray-scale voltage at least includes a first gray-scale voltage and a second gray-scale voltage.

[0042] For an ink screen, the first grayscale voltage may be a voltage for driving black particles to display; and the second grayscale voltage may be a voltage for driving white particles to display.

[0043] like Figure 6 As shown, the driving module 300 has: a first voltage output port 301, a second voltage output port 302 and a driving port 303; The first voltage output port 301 is used to output a first grayscale voltage, so that any pixel in the ink screen can display a first grayscale according to the first grayscale voltage; The second voltage output port 302 is used to output a second grayscale voltage, so that any pixel in the ink screen can display a second grayscale according to the second grayscale voltage; The driving port 303 is used to receive a grayscale driving signal, so that the driving module outputs a first grayscale voltage through a first voltage output port or outputs a second grayscale voltage through a second voltage output port according to the grayscale driving signal.

[0044] Specifically, the driving module 300 includes: a transistor T, an inductor L, a first diode D1, a second diode D2, a third diode D3, a first resistor R1, a second resistor R2, a first capacitor C1, a second capacitor C2, a third capacitor C3 and a fourth capacitor C4; The transistor comprises: a transistor first electrode T1, a transistor second electrode T2 and a transistor third electrode T3; The first electrode T1 of the transistor is electrically connected to one end of the first resistor R1 and serves as a driving port 303. The second electrode T2 of the transistor is electrically connected to one end of the second resistor R2. The other end of the first resistor R1 is electrically connected to the other end of the second resistor R2 and then grounded. The third electrode T3 of the transistor is electrically connected to one end of the inductor L, one end of the second capacitor C2 and the anode of the third diode D3. The other end of the inductor L is electrically connected to one end of the fourth capacitor C4 and then connected to the power supply V CC The other end of the fourth capacitor C4 is grounded, the cathode of the third diode D3 is electrically connected to one end of the first capacitor C1 and serves as the first voltage output port 301, the other end of the first capacitor C1 is electrically connected to the cathode of the first diode D1 and then grounded, the anode of the first diode D1 is electrically connected to the other end of the second capacitor C2 and the cathode of the second diode D2, the anode of the second diode D2 is electrically connected to one end of the third capacitor C3 and serves as the second voltage output port 302, and the other end of the third capacitor C3 is grounded.

[0045] Preferably, the driving module 300 further includes: a third resistor R3.

[0046] The third resistor R3 is connected in parallel to both ends of the second resistor R2. The third resistor R3 can be used to adjust the total resistance value from the second electrode of the transistor to the ground.

[0047] Preferably, the power supply V CC It is a 3.3V power supply.

[0048] Preferably, the transistor T is a metal-oxide-semiconductor field effect transistor. The first electrode T1 of the transistor is a gate electrode, the second electrode T2 of the transistor is a source electrode, and the third electrode T3 of the transistor is a drain electrode. The inductor L, the transistor T, the first capacitor C1, the third diode D3, and the second resistor R2 form a boost circuit, and the on or off state of the transistor T is controlled by the grayscale drive signal.

[0049] When the transistor T is turned on, the input voltage passes through the inductor L directly through the second resistor R2 to the ground, so that the current of the inductor L increases linearly. At this time, the output first capacitor C1 discharges to the load.

[0050] When the transistor T is turned off, since the current of the inductor L cannot change suddenly in an instant, a reverse electromotive force is generated on the inductor L to maintain the current passing through unchanged. At this time, the third diode D3 is turned on, and power is supplied to the load with a voltage exceeding the power supply voltage of 3.3V, and the first capacitor C1 is charged. This cycle is repeated to achieve voltage boosting, and the boosted voltage is output from the first voltage output port 301.

[0051] When the transistor T is turned off, the second capacitor C2 is charged, the first diode D1 is turned on, the second diode D2 is turned off, and the current flows to the ground through the first diode D1.

[0052] When the transistor T is turned on, the drain of the transistor T is close to 0V, the second capacitor C2 is discharged, the first diode D1 is turned off, the second diode D2 is turned on, and the current flows to the second capacitor C2 through the second diode D2, thereby achieving "boosting" of the reverse voltage, and the reverse voltage is output from the second voltage output port 302.

[0053] Specifically, the display control module 400 has a pixel control port 401, which is used to determine the pixel receiving the grayscale voltage.

[0054] In other embodiments, Figure 7 As shown, a method for displaying information of an external device is provided, and the method is applied to the electronic device described in the first aspect, comprising: S100: Acquire a one-to-one mapping relationship between at least one display area and at least one external device slot; S200: Acquire device information of an external device connected to at least one external device slot; S300: Displaying device information of an external device connected to a corresponding external device slot in at least one display area according to the mapping relationship and the device information.

[0055] The purpose of acquiring device information is to save the display content to the buffer of the display screen, and then display the display content in the buffer on the display screen.

[0056] Usually, it is to convert image data or text data into the format required by the display screen through SPI or I 2 The C interface sends data to the display's buffer. Schematically, sending: DATA_START_TRANSMISSION_1 command; And DATA_START_TRANSMISSION_2 command, and then send data. This application does not limit the specific content of the command for obtaining device information.

[0057] Take the use of an ink screen to display device information as an example: corresponding to the actual position layout of the slot, obtain the classification code and slot number of the device information of the device connected to the external device slot.

[0058] Specifically, S200: obtaining device information of an external device connected to at least one external device slot includes: S210: Obtain a device model of at least one external device installed in the server model, and determine a physical address of the external device according to the device model; S220: Determine the slot number connected to the external device according to the physical address of the external device; S230: Determine the classification code of the external device according to the device model, and use the classification code as the device information.

[0059] Illustratively, the classification code of the external device may be 01h for a storage controller, 02h for a network controller, 03h for a display controller, 04h for a media controller, and so on.

[0060] Preferably, the external device information display method further includes: S240: Dividing at least one display area of ​​the display device according to the physical position distribution of at least one external device slot; S250: Associating at least one display area with a slot number.

[0061] Specifically, before S100: obtaining a one-to-one mapping relationship between at least one display area and at least one external device slot, the method further includes: S010: Setting the display start position of the display device; Usually, this is achieved by specifying the starting coordinates of the content displayed on the display screen. Schematically, by sending to the display screen: SET_RAM_X_ADDRESS_START_END_POSITION command; The SET_RAM_Y_ADDRESS_START_END_POSITION command is implemented. The present application does not limit the specific content of the start position setting command.

[0062] Setting the starting coordinates of the display area can specify the starting position of the content displayed on the ink screen.

[0063] S020: Set the display area size of the display device.

[0064] Specifically, it includes setting the length of the display area and setting the width of the display area. By setting the size of the display area, the size of the display area on the display screen for displaying the displayed content is defined. Schematically, by sending to the display screen: SET_RAM_X_ADDRESS_COUNT command; And the SET_RAM_Y_ADDRESS_COUNT command is implemented. The present application does not limit the specific content of the actual area size setting command.

[0065] Setting the length and width of the display area defines the size of the area where content is displayed on the ink screen.

[0066] Preferably, before S010: setting the display start position of the display device, the method further includes: S001: Initialize the input and output ports of the display device; S002: Perform a hardware reset and / or a software reset on the display device.

[0067] Usually, the input and output ports of the display are initialized during the server startup phase. Initialize the input and output ports of the display to ensure that the hardware resources are ready to receive and send data.

[0068] Taking the ink screen as an example, the specific steps include: initializing the GPIO (General Purpose Input / Output) port and setting the mode of each pin.

[0069] Configure the SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit) port to communicate with the ink screen.

[0070] If an interrupt pin exists, set the interrupt pin.

[0071] Initialize hardware resources such as clock and power management.

[0072] Performing a hardware reset and / or software reset on the display can restore the display to a known initial state, ensuring the correctness of subsequent operations.

[0073] Taking the ink screen as an example, the ink screen hardware is reset by pulling down the reset pin and maintaining it for a period of time (usually a few milliseconds); Send the preset reset command to the ink screen to complete the software reset.

[0074] Preferably, in response to the update of the category code and / or the slot number, the display screen is initialized to display the updated category code and slot number.

[0075] Preferably, in response to the display screen being awakened from a sleep state, a hardware reset and / or a software reset are sequentially performed on the display screen, and after display parameters are set on the display screen, a classification code and a slot number are displayed.

[0076] Full screen refresh: The entire page is refreshed once, and the entire screen flashes several times. The advantage is that there is no residual image, but the disadvantage is that you need to refresh the screen several times more.

[0077] Partial refresh: Each time the display content is refreshed, the entire screen will not be refreshed, only the areas with pictures and words will be refreshed. The advantage is that the screen will not flicker, but there will be residual images.

[0078] When implementing the global refresh and partial refresh functions of the ink screen, you must enter initialization and then refresh after going into sleep mode when switching from partial refresh to full refresh.

[0079] It should be understood that although Figure 7 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 7 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0080] In some other embodiments, a computer program product is provided, including a computer program, and when the computer program is executed by a processor, the method for displaying external device information according to the second aspect is implemented. Specifically, it includes: S100: Acquire a one-to-one mapping relationship between at least one display area and at least one external device slot; S200: Acquire device information of an external device connected to at least one external device slot; S300: Displaying device information of an external device connected to a corresponding external device slot in at least one display area according to the mapping relationship and the device information.
