[0036] It should be noted that, in some optional embodiments, the above Figure 1 The computer device (or electronic device) shown may include hardware elements (including circuits), software elements (including computer code stored on a computer-readable medium), or a combination of hardware elements and software elements. It should be noted that Figure 1 This is merely one example of a particular embodiment and is intended to illustrate the types of components that may be present in the above-described computer device (or electronic device).

[0037] In the above-mentioned operating environment, an embodiment of the present application provides an embodiment of a display control method for a display screen. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 2 FIG. 1 is a flow chart of a display control method of a display screen according to an embodiment of the present invention. Figure 2 As shown, the method may include the following steps:

[0039] Step S202, obtaining at least one image data packet from a controller.

[0040] In the technical solution provided in the above step S202 of the present invention, the above at least one image data packet can be obtained by packaging and processing the image data of the target image by the controller, and the above image data can be used to display the above target image on a display screen controlled by the controller. For example, the image data packet can be 64 pixels, and the image data can be collected by a camera device connected to the controller. The camera device may include: a camera, a video camera, etc., which is only used as an example here and is not specifically limited.

[0041] In this embodiment, at least one image data packet is obtained from the controller. For example, an image data packet can be obtained by packaging the collected image data through the controller. The image data packet is sent to the interface chip through the controller. After the interface chip receives the sent image data packet, if there is a free space in the storage location of the interface chip, the acquisition of another image data packet from the controller continues. If there is no free space in the storage location of the interface chip, the acquisition of another image data packet from the controller is suspended until there is a free space in the storage location, and the acquisition of another image data packet from the controller is resumed. The free space can be used to represent the free space (Bank) existing in the storage location of the interface chip.

[0042] Optionally, the image data can also be collected through an application connected to the controller. For example, the application can communicate data with the controller through a local area network or the Internet. The image data can be stored in different formats. For example, the image data can be stored in a bitmap format, or the image data can be stored in a vector format.

[0043] Step S204: generating driving data required by a driving device of the display screen based on the image data packet.

[0044] In the technical solution provided in the above step S204 of the present invention, the above driving data can be used to represent the timing of the driving IC. For example, the driving data can become the driving timing after being output from the interface chip, which may include a data signal (DATA), a latch signal (LATCH), a grayscale display control signal (OE / ROW / GCLK), a row signal (ABCDE), a pixel clock signal (DCLK), etc.

[0045] In this embodiment, after acquiring at least one image data packet from the controller, driving data required by the driving device of the display screen is generated based on the image data packet. For example, the acquired image data packet is sent to the interface chip through the controller. After the interface chip receives the image data packet, the image data packet is parsed to obtain a parsed image data packet. The parsed image data packet is then subjected to timing conversion processing, thereby obtaining the timing of the driving IC.

[0046] Optionally, the interface chip can send the timing of the driver IC to the driver chip, wherein the interface chip can include at least the following modules: a data analysis module and a timing generation module, the data analysis module can be used to analyze and process the received image data packets, and the timing generation module can be used to perform timing conversion processing on the analyzed image data packets.

[0047] Step S206: Based on the driving data, control the driving device to drive the display screen to display the target image.

[0048] In the technical solution provided in the above step S206 of the present invention, the above driving device can be used to drive the display screen to display the target image. For example, the above driving device can be a driving IC, which is only used as an example and is not specifically limited.

[0049] In this embodiment, after the driving data required by the driving device of the display screen is generated based on the image data packet, the driving device is controlled to drive the display screen to display the target image based on the driving data. For example, the driving data output by the interface chip is sent to the driving IC. After the driving IC receives the driving data, the display screen is driven to display the target image, that is, the light emitting diode (LED) light board is driven to display the target image.

[0050] Optionally, while the driving data output by the interface chip is sent to the driver IC, the row signal (ABCDE) in the driving data is sent to the row decoder. After the row decoder receives the row signal (ABCDE), the display screen is driven to display the target image in row sequence by controlling the row tube.

[0051] In the related art, the timing generator is usually directly integrated into the controller, but the light board modules on the market use a wide variety of driver ICs, which requires the controller to continuously iterate and change the timing corresponding to different driver ICs, which dramatically increases the complexity of docking, making the controller more and more complex and difficult to maintain, thereby leading to the technical problem of low efficiency in display control of the display screen. For example, FIG3(a) is a schematic diagram of a connection method between a controller and an interface chip according to the related art. As shown in FIG3(a), the controller 301 can be connected to the interface chip 302, the interface chip 302 can be connected to the row decoder 303 and the driver chip 304, the row decoder 303 can be connected to the row tubes 3051 to 30531, the driver chip 304 can be connected to the LED light board 306, and the row tubes 3051 to 30531 can also be connected to the LED light board 306.

[0052] Optionally, the controller 301 may include: an image processing module 3011 and a timing generation module 3012, and the interface chip 302 may include: a data analysis module 3021, wherein the image processing module 3011 can be used to preprocess the image data, the timing generation module 3012 can be used to perform timing conversion processing on the preprocessed image data, and the data analysis module 3021 can be used to perform analysis processing on the image data after timing conversion.

[0053] Optionally, the controller 301 can send a low voltage differential signal (LVDS) to the interface chip 302, the interface chip 302 can send a low voltage differential signal (LVDS) to the controller 301, the interface chip 302 can also send a row signal (ABCDE) to the row decoder 303, and the interface chip 302 can also send a data signal, a latch signal, a grayscale display control signal, a pixel clock signal, etc. to the driver chip 304.

[0054] However, in the solution implemented by the above steps S202 to S206 of the present application, the interface chip can obtain at least one image data packet from the controller, and can generate the driving data required by the driving device of the display screen according to the obtained image data packet, and can control the driving device to drive the display screen to display the target image according to the generated driving data. In other words, the interface chip in the present application can obtain the image data packet, and the interface chip can generate the driving data according to the image data packet, so as to drive the driving device of the display screen through the driving data, thereby driving the display screen to display the target image, thereby achieving the purpose of simplifying the design of the front-end controller and reducing the iteration of the front-end controller, thereby solving the technical problem of low efficiency of display control of the display screen, and further achieving the technical effect of improving the efficiency of display control of the display screen.

[0055] The above method of this embodiment is further introduced below.

[0056] As an optional implementation, step S202, obtaining at least one image data packet from the controller, includes: sequentially obtaining at least one image data packet from the controller.

[0057] In this embodiment, the sequential acquisition may be performed in the order in which the image data is sent.

[0058] Optionally, at least one image data packet from the controller is acquired in sequence. For example, when the controller receives multiple image data, the multiple image data are preprocessed in parallel according to the order in which the multiple image data are sent, and then the preprocessed multiple image data are packaged respectively, and then the packaged multiple image data packets are sent respectively to the data parsing module in the interface chip. If there is free space in the storage location, the image data packet continues to be sent to the data parsing module in the interface chip. If there is no free space in the storage location, the sending of the image data packet to the data parsing module in the interface chip is suspended until there is free space in the storage location, and then the sending of the image data packet to the data parsing module in the interface chip is resumed, thereby achieving the technical effect of orderly acquiring image data packets from the controller in sequence.

[0059] Optionally, a timing generation module may be integrated in the interface chip, wherein the timing generation module may be connected to the data parsing module, and the timing generation module may be used to perform timing conversion processing on the parsed image data packets.

[0060] In this embodiment, it is necessary to sequentially obtain image data packets from the controller. The following further introduces how to sequentially obtain image data packets from the controller.

[0061] As an optional embodiment, at least one image data packet from the controller is sequentially obtained, including: obtaining a first image data packet in at least one image data packet; in response to allowing the controller to send a second image data packet to the interface chip, obtaining a second image data packet from the controller; in response to the existence of a third image data packet next to the second image data packet in at least one image data packet, determining the third image data packet as the second image data packet, and starting from the following steps: in response to allowing the controller to send a second image data packet to the interface chip, obtaining the second image data packet from the controller, until the second image data packet is the last image data packet in the at least one image data packet.

[0062] In this embodiment, the second image data packet may be the next image data packet of the first image data packet in at least one image data packet.

[0063] Optionally, the interface chip obtains a first image data packet sent by the controller, and then determines whether the controller is allowed to continue to send a second image data packet to the interface chip. If the controller is allowed to continue to send the second image data packet to the interface chip, the interface chip obtains the second image data packet sent by the controller, and then determines whether the second image data packet has a next third image data packet in at least one image data packet. If the second image data packet has a next third image data packet in at least one image data packet, the third image data packet is determined to be the second image data packet, and execution is started from the following steps: determining whether the controller is allowed to continue to send the second image data packet to the interface chip. If the controller is allowed to continue to send the second image data packet to the interface chip, the second image data packet sent by the controller is obtained until the second image data packet is the last image data packet in at least one image data packet, thereby achieving the technical effect of being able to obtain image data packets from the controller in sequence.

[0064] Optionally, if the controller is not allowed to continue sending the second image data packet to the interface chip, the controller stops sending the second image data packet to the interface chip, and the interface chip also stops acquiring the second image data packet sent by the controller.

[0065] In this embodiment, when there is free space in the storage location, the controller continues to send the second image data packet to the interface chip. The following further introduces how the controller continues to send the second image data packet to the interface chip when there is free space in the storage location.

[0066] As an optional implementation manner, the display control method of the display screen further includes: in response to not sending the first response information to the controller, determining to allow the controller to send the second image data packet to the interface chip.

[0067] In this embodiment, the first response information may be used to indicate that the controller is prohibited from sending the second image data packet to the interface chip. For example, the first response information may be a busy data packet.

[0068] Optionally, in response to not sending the first response information to the controller, it is determined that the controller is allowed to send the second image data packet to the interface chip. For example, it is judged whether the interface chip sends a Busy data packet to the controller. If the interface chip has not sent a Busy data packet to the controller, it is determined that the controller is allowed to send the second image data packet to the interface chip. If the interface chip has sent a Busy data packet to the controller, it is determined that the controller is not allowed to send the second image data packet to the interface chip, thereby achieving the technical effect of determining whether the controller is allowed to send the second image data packet to the interface chip based on whether there is free space in the storage location.

[0069] For example, a ping-pong random access memory (RAM) is designed inside the interface chip, where the RAM can store a data packet of 128 pixels in size, which contains 64 pixels of grayscale data. When a data packet starts to be received, it is determined whether there is an empty bank to store the next data packet. If there is an empty bank to store the next data packet, the interface chip does not need to send the Busy data packet to the controller, and the controller can continue to send 64-pixel image data packets to the interface chip.

[0070] Figure 3(b) is a schematic diagram of a connection method between a controller and an interface chip according to an embodiment of the present invention. As shown in Figure 3(b), the controller 301 can be connected to the interface chip 302, the interface chip 302 can be connected to the row decoder 303 and the driver chip 304, the row decoder 303 can be connected to the row tubes 3051 to 30531, the driver chip 304 can be connected to the LED light board 306, and the row tubes 3051 to 30531 can also be connected to the LED light board 306.

[0071] Optionally, the controller 301 may include: an image processing module 3011 and an image packaging module 3013, and the interface chip 302 may include: a data analysis module 3021 and a timing generation module 3023, wherein the image processing module 3011 can be used to preprocess the image data, the image packaging module 3013 can be used to package the preprocessed image data, the data analysis module 3021 can be used to analyze the image data packet, and the timing generation module 3023 can be used to perform timing conversion on the analyzed image data packet.

[0072] Optionally, the controller 3013 can send a low voltage differential signal (LVDS) to the interface chip 302, the interface chip 302 can send a low voltage differential signal (LVDS) to the controller 301, the interface chip 302 can also send a row signal (ABCDE) to the row decoder 303, and the interface chip 302 can also send a data signal (DATA), a latch signal (LATCH), a grayscale display control signal (GCLK), a pixel clock signal (DCLK), etc. to the driver chip 304.

[0073] In this embodiment, it is necessary to send the second image data packet to the interface chip through the controller. The following further introduces how to send the second image data packet to the interface chip through the controller.

[0074] As an optional embodiment, after acquiring the first image data packet in at least one image data packet, the display control method of the display screen also includes: in response to the storage location of the interface chip prohibiting the storage of the second image data packet, sending a first response message to the controller; in response to the storage location of the interface chip allowing the storage of the second image data packet, sending a second response message to the controller.

[0075] In this embodiment, the above-mentioned storage location can be used to represent the internal storage space of the interface chip, and the above-mentioned second response information can be used to indicate that the controller is allowed to send a second image data packet to the interface chip. For example, the above-mentioned storage location can be represented by a Bank, and the above-mentioned second response information can be a release (Release) data packet. The above-mentioned storage permission can be used to indicate that an empty Bank can store the next data packet.

[0076] Optionally, after acquiring the first image data packet in at least one image data packet, a judgment is made as to whether the storage location of the interface chip prohibits the storage of the second image data packet. If the storage location of the interface chip prohibits the storage of the second image data packet, the interface chip sends a Busy data packet to the controller. If the storage location of the interface chip allows the storage of the second image data packet, the interface chip sends a Release data packet to the controller, thereby achieving the technical effect of being able to resume sending image data packets to the interface chip.

[0077] For example, if there is no empty bank to store the next data packet, the interface chip sends the Busy data packet to the controller, the controller suspends sending 64-pixel image data packets to the interface chip, and the interface chip also suspends obtaining the image data packets sent by the controller.

[0078] For another example, if there is an empty bank to store the next data packet, the interface chip sends the Release data packet to the controller, the controller resumes sending 64-pixel image data packets to the interface chip, and the interface chip also resumes obtaining the image data packets sent by the controller.

[0079] In this embodiment, when the interface chip outputs driving data, the interface chip sends second response information to the controller. The following further introduces how the interface chip sends the second response information to the controller when the interface chip outputs driving data.

[0080] As an optional implementation manner, the display control method of the display screen further includes: sending second response information to the controller in response to outputting driving data corresponding to the first image data packet.

[0081] In this embodiment, the driving data may be output by a timing generation module in the interface chip.

[0082] Optionally, in response to outputting the driving data corresponding to the first image data packet, a second response message is sent to the controller. For example, a judgment is made as to whether the timing generation module in the interface chip outputs the driving data corresponding to the first image data packet. If the timing generation module outputs the driving data corresponding to the first image data packet, there is currently an empty Bank that can store a new data packet, and the interface chip sends a Release data packet to the controller, thereby achieving the technical effect of being able to resume sending image data packets to the interface chip.

[0083] In this embodiment, it is necessary to determine whether to send the response information to the controller according to the bandwidth of the transmitting end and the bandwidth of the receiving end. The following further introduces how to determine whether to send the response information to the controller according to the bandwidth of the transmitting end and the bandwidth of the receiving end.

[0084] As an optional implementation, the display control method of the display screen also includes: sending a first response message to the controller, including: in response to the bandwidth of the transmitting end of the interface chip not matching the bandwidth of the receiving end of the interface chip, sending the first response message to the controller; sending a second response message to the controller, including: in response to the bandwidth of the transmitting end not matching the bandwidth of the receiving end, sending the second response message to the controller.

[0085] In this embodiment, the above-mentioned receiving end can be used to receive an image data packet from a controller using a corresponding bandwidth, and the above-mentioned transmitting end can be used to output driving data corresponding to the image data packet using a corresponding bandwidth. For example, the above-mentioned receiving end can be a receiving end in an interface chip that receives LVDS data, and the above-mentioned transmitting end can be a transmitting end that outputs driving data by a timing generation module in the interface chip.

[0086] Optionally, a judgment is made as to whether the bandwidth of the transmitting end of the interface chip matches the bandwidth of the receiving end of the interface chip. If the bandwidth of the transmitting end of the interface chip does not match the bandwidth of the receiving end of the interface chip, the interface chip sends a Busy data packet to the controller, or the interface chip sends a Release data packet to the controller, thereby achieving the technical effect of determining whether to send a response message to the controller based on the bandwidth of the transmitting end and the bandwidth of the receiving end.

[0087] Optionally, if the bandwidth of the transmitting end of the interface chip does not match the bandwidth of the receiving end of the interface chip, and there is no empty bank to store the next data packet, the interface chip sends a Busy data packet to the controller, the controller suspends sending image data packets to the interface chip, and the interface chip also suspends obtaining image data packets sent by the controller.

[0088] Optionally, if the bandwidth of the transmitting end of the interface chip does not match the bandwidth of the receiving end of the interface chip, and there is an empty bank to store the next data packet, the interface chip sends a Release data packet to the controller, the controller resumes sending image data packets to the interface chip, and the interface chip also resumes obtaining image data packets sent by the controller.

[0089] Figure 4(a) is a schematic diagram of the output bandwidth of an interface chip and the bandwidth of an LVDS interface according to an embodiment of the present invention. As shown in Figure 4(a), when the output bandwidth of the interface chip is higher than the bandwidth of the LVDS interface, there is an IDLE data packet between the Busy data packet and the Release data packet, and there is an IDLE data packet between different output data output by the timing generator. When the transmission of the current image data packet is completed, the next image data packet can be sent immediately.

[0090] In this embodiment, it is necessary to determine whether to send the response information to the controller according to the bandwidth of the transmitting end and the bandwidth of the receiving end. The following further introduces how to determine whether to send the response information to the controller according to the bandwidth of the transmitting end and the bandwidth of the receiving end.

[0092] In this embodiment, it is judged whether the bandwidth of the transmitting end of the interface chip matches the bandwidth of the receiving end of the interface chip. If the bandwidth of the transmitting end of the interface chip matches the bandwidth of the receiving end of the interface chip, the sending of the Busy data packet by the interface chip to the controller is canceled, or the sending of the Release data packet by the interface chip to the controller is canceled, thereby achieving the technical effect of determining whether to send a response message to the controller based on the bandwidth of the transmitting end and the bandwidth of the receiving end.

[0093] Optionally, if the bandwidth of the transmitting end of the interface chip matches the bandwidth of the receiving end of the interface chip, and there is no empty bank to store the next data packet, the controller suspends sending image data packets to the interface chip, and the interface chip also suspends obtaining image data packets sent by the controller.

[0094] Optionally, if the bandwidth of the transmitting end of the interface chip matches the bandwidth of the receiving end of the interface chip, and there is an empty bank to store the next data packet, the controller resumes sending image data packets to the interface chip, and the interface chip also resumes obtaining image data packets sent by the controller.

[0095] FIG4(b) is a schematic diagram of another interface chip output bandwidth and LVDS interface bandwidth according to an embodiment of the present invention. As shown in FIG4(b), when the output bandwidth of the interface chip is lower than the bandwidth of the LVDS interface, the controller of the previous stage will be back-pressured. For example, there is an IDLE data packet between the Busy data packet and the Release data packet, and there is no IDLE data packet between the different output data output by the timing generator. After the controller receives the Release data packet, it can resume sending the next image data packet.

[0096] In this embodiment, the image data needs to be converted into a driving timing sequence. The following further introduces how to convert the image data into a driving timing sequence.

[0099] Optionally, the acquired image data packet is sent to the interface chip through the controller. After the interface chip receives the image data packet, the image data packet is parsed to obtain a parsed image data packet, and then the parsed image data packet is subjected to timing conversion processing, thereby obtaining a timing that meets the timing requirements of the driver IC, thereby achieving the technical effect of converting image data into drive timing, and further avoiding the problem of constantly iterating and changing the chip of the controller system when connecting modules driven by different driver ICs when a timing generator is integrated in the controller.

[0105] Optionally, in response to synchronization data, drive data is output. For example, during data synchronization, a synchronization data packet is used. When each interface chip receives the synchronization data packet, the internal state of the chip is synchronized to maintain synchronization of the output timing, thereby achieving the technical effect of maintaining synchronous output of the drive data.
