[0049] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation to the screen driving device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0052] Based on the above hardware structure, an embodiment of a screen driving method of the present invention is proposed.

[0053] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a screen driving method according to the present invention.

[0054] In a first embodiment, the screen driving method includes the following steps:

[0055] Step S10: upon receiving a test image card instruction, generating target image data according to the test image card instruction and the image to be processed.

[0056] It should be noted that the executor of this embodiment is a screen driving device, and it can also be other devices that can achieve the same or similar functions, such as a screen driving controller, etc. This embodiment does not limit this. In this embodiment, the screen driving controller is used as an example for explanation.

[0057] It should be understood that reference Figure 3 , Figure 3 It is a schematic diagram of the overall architecture, including: a host computer, a screen drive controller and a target screen device, and the screen drive controller is connected to the host computer and the target screen device respectively. The screen drive controller includes an instruction processing unit, an image control unit and a bridge chip unit, and the bridge chip unit is connected to the image control unit and the instruction processing unit respectively. Optionally, the instruction processing unit is used to receive screen configuration instructions, test image card instructions and display image card instructions sent by the host computer, the instruction processing unit is used to parse the received screen configuration instructions, test image card instructions and display image card instructions, the image control unit is used to configure the timing of the target color timing generator, switch the display image card, and generate the target color timing, the bridge chip unit is used to establish communication with the target device screen, initialize the target device screen, generate the target communication timing and send the image card image data, and the target device screen is used to display the image card image data.

[0058] It can be understood that the test picture card instruction refers to the test instruction for driving the screen through the picture card. The test picture card instruction is sent by the host computer to the instruction processing unit of the screen drive controller. The processing object of the image to be processed is the instruction processing unit. The target image data refers to the image data that needs to be displayed on the test picture card.

[0059] Furthermore, step S10 includes: upon receiving a test picture card instruction, decoding the image to be processed according to the test picture card instruction to obtain a current decoded image; and identifying the current decoded image to obtain target image data.

[0060] It can be understood that the currently decoded picture refers to the picture after decoding the picture to be processed. Specifically, after the instruction processing unit receives the test picture card instruction sent by the upper computer, it decodes the picture to be processed corresponding to the test picture card instruction, and then sends the currently decoded picture to the image control unit. The image control unit then identifies the currently decoded image, obtains the target image data, and then saves the target image data to its own data storage memory.

[0061] Furthermore, before step S10, it also includes: when receiving a screen configuration instruction, parsing the screen configuration instruction to obtain current screen information; configuring the timing of the target color timing generator according to the current screen information and the screen configuration instruction; establishing communication with the target device screen according to the current screen information and the screen configuration instruction, and initializing the parameters of the target device screen; after the timing configuration and parameter processing are completed, determining whether a test image card instruction sent by the host computer is received.

[0062] It can be understood that the current screen information refers to the relevant attribute information of the target device screen, which includes but is not limited to screen display information (VSA, HAS, VBP, HBP, VFP, HFP, HACT and VACT), screen power-on sequence and screen power-off sequence and other information. The target color timing generator can be an RGB timing generator. After obtaining the current screen information, the instruction processing unit will send the current screen information to the image control unit and the bridge chip unit, and the image control unit and the bridge chip unit will also receive the screen configuration instruction. Then the image control unit completes the configuration of the timing of the target color timing generator according to the current screen information and the screen configuration instruction, and the bridge chip unit establishes communication with the target device screen according to the current screen information and the screen configuration instruction, and completes the initialization processing of the parameters of the target device screen.

[0063] Step S20 : upon receiving a display card instruction, generating a target color timing according to the display card instruction.

[0064] It can be understood that the target color timing can be an RGB timing, which is generated by an RGB timing generator. The display card instruction refers to an instruction for displaying the image to be tested. After receiving the display card instruction, the instruction processing unit parses the display card instruction, and then the RGB timing generator generates the target color timing based on the parsed current card display information.

[0065] Furthermore, step S20 includes: when receiving a display card instruction, parsing the display card instruction to obtain current card display information; obtaining current timing parameters according to the current card display information; and generating a target color timing according to the current timing parameters.

[0066] It should be understood that the current image card display information refers to the relevant attribute information of the image that needs to be displayed at present. For example, the current image card display information includes but is not limited to information such as the display image card number and timing parameters. After obtaining the current image card display information, the current timing parameters are extracted from the current image card display information, and then the target color timing is generated according to the current timing parameters.

[0067] Step S30 , generating a target communication timing according to the target color timing, and generating a chart image data according to the target image data.

[0068] It should be understood that the target communication timing can be a MIPI communication timing. In this embodiment, the data interaction between the bridge chip unit and the target device screen is completed through the target communication timing. After receiving the target color timing sent by the image control unit, the bridge chip unit generates the target communication timing, and generates the picture card image data according to the target image data. The picture card image data refers to the data after the target image data to be displayed is merged with the picture card to be tested, and the picture card to be tested is sent to the image control unit by the host computer through a network cable or USB.

[0069] Step S40 , lighting up and displaying the image card data on the target device screen according to the target communication timing.

[0070] Furthermore, step S40 includes: sending the picture card image data to a target device controller through the target communication sequence, so that the target device controller controls the target device screen to light up and display the picture card image data.

[0071] It should be understood that the target device controller refers to the controller that controls the target device screen. After obtaining the picture card image data, the bridge chip unit sends the picture card image data to the target device controller through the target communication timing, and then the target device controller controls the target device screen to light up and display the picture card image data to complete the driving of the target device screen. Specifically, the picture card image data is sent to the target device screen through the target communication timing using the C-PHY and DPHY protocols, and then the target device screen displays the picture card image data to complete the screen power display function. The target device screen can be an XR screen. When the screen test item changes, you only need to switch to different test picture cards.

[0072] This embodiment generates target image data according to the test image card instruction and the image to be processed when a test image card instruction is received; generates a target color timing according to the display image card instruction when a display image card instruction is received; generates a target communication timing according to the target color timing, and generates image card image data according to the target image data; and lights up and displays the image card image data on the target device screen according to the target communication timing. In the above manner, the target color timing is generated according to the target image data, and the image card image data is generated according to the target image data, and then the image card image data is lit up and displayed on the target device screen, thereby effectively improving the screen driving efficiency and being applicable to screen driving in multiple scenarios.

[0073] In one embodiment, if Figure 4 Based on the first embodiment, a second embodiment of the screen driving method of the present invention is proposed. Step S30 includes:

[0074] Step S301 : obtaining a corresponding timing type according to the target color timing, and determining a timing conversion strategy according to the timing type.

[0075] It should be understood that the timing type refers to the type to which the target color timing belongs, and the timing conversion strategy refers to the strategy for converting different types of timings into each other, and different timing types correspond to different timing conversion strategies. After obtaining the timing type to which the target color timing belongs, the timing conversion strategy corresponding to the timing type is selected from the timing conversion strategy set according to the timing type. For example, the target color timing belongs to the RGB timing type, and the sequence type of the target communication sequence is the MIPI timing type. According to the above two conditions, the timing conversion strategy with the best performance match is selected from the timing conversion strategy set in the timing type, and then the target color timing is converted using the timing conversion strategy.

[0076] Step S302: convert the target color timing according to the timing conversion strategy to obtain a target communication timing.

[0077] It is understandable that after the timing conversion strategy is determined, the target color timing is converted into the target communication timing according to the timing conversion strategy, and the target communication timing may be the MIPI communication timing.

[0078] Step S303: Generate image card data according to the target image data.

[0079] It should be understood that after obtaining the target image data, the target image data is fused with the image card to be tested to generate image card image data, and the image card image data is used to drive the lighting display function of the target device screen.

[0080] Furthermore, step S303 includes: obtaining a display card number based on the current image display information; when the number of the current display card is inconsistent with the display card number, switching the current display card to a display card corresponding to the display card number; and generating card image data based on the display card and the target image data.

[0081] It can be understood that the display card number refers to the number of the card to be tested. After obtaining the display card number, it is determined whether the number of the current display card is consistent with the display card number. If not, it indicates that the display card needs to be switched, that is, the current display card is switched to the display card corresponding to the display card number. If so, there is no need to switch the display card, and then the final display card is merged with the target image data to obtain the card image data. For example, the current display card is numbered 001, and the card to be tested is numbered 004. At this time, it is necessary to switch the display card, that is, switch the current display card to the display card corresponding to number 004. If the subsequent test items change, the display card corresponding to number 004 can be directly switched to the display card corresponding to other numbers.

[0082] This embodiment obtains a corresponding timing type based on the target color timing, and determines a timing conversion strategy based on the timing type; converts the target color timing according to the timing conversion strategy to obtain a target communication timing; and generates picture card image data based on the target image data. In the above manner, a timing conversion strategy is determined based on the type of the target color timing, and then the target color timing is converted into a target communication timing using the timing conversion strategy, and picture card image data is generated based on the target image data and the display picture card, thereby effectively improving the accuracy of obtaining the target communication timing and picture card image data.
