[0055] Through the above - mentioned drawings, the clear embodiments of the present application have been shown, and there will be more detailed descriptions later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to explain the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0056] To make the purpose, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0057] The screen driving board is a component in a display device. The screen driving board may include a timing control chip, a storage component, and multiple function controllers. The function controllers may include various function controllers such as a power controller and a gamma controller. The timing control chip and these function controllers can jointly drive and control the display panel to achieve the display function.

[0058] However, it is difficult to update the programs of the function controllers in the above-mentioned screen driving board. In the related art, when updating the programs of various function controllers in the screen driving board, the function controllers are removed from the screen driving board, and an updated program is written into various function controllers through a burner. The update process of such a screen driving board is relatively cumbersome, time-consuming, and inefficient.

[0059] The embodiments of the present application provide a screen driving board, an update method thereof, a display device, and a computer storage medium, which can solve some problems in the above-mentioned related art.

[0060] Figure 1 It is a schematic structural diagram of a display device provided by an embodiment of the present application. The display device includes a first controller 11, a screen driving board 12, and a display panel 13.

[0061] The first controller 11 is electrically connected to the screen driving board 12, and the screen driving board 12 is electrically connected to the display panel 13.

[0062] The first controller 11 may include a system-on-chip (SOC). The first controller 11 can send instructions and some programs to the screen driving board 12.

[0063] The screen driving board 12 includes a timing control chip (TCON IC) 121, a storage component 122, and multiple function controllers 123. The timing control chip 121 is electrically connected to the storage component 122, and the timing control chip 121 is respectively electrically connected to multiple function controllers ( Figure 1 For example, function controller a, function controller b, and function controller c are used for illustration, but are not limited thereto). The multiple function controllers (a, b, c) may include a power management integrated circuit (PMIC), a programmable gamma correction buffer integrated circuit (Pgamma IC), and a level shift integrated circuit (levelshift, IC), etc. Among them, the PMIC can be used to generate various voltages required for the operation of the display panel 13, such as voltages like VGH (gate high-level voltage) and VGL (gate low-level voltage); the Pgamma IC can be used to generate the gamma voltage and VCOM voltage of the display panel 13 (the VCOM voltage can be a reference voltage).

[0064] The screen driving board 12 can also be referred to as a logic board, a central control board, or a TCON board.

[0065] The display panel 13 can be a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, a micro light-emitting diode display (Micro LED), or other display panels.

[0066] The storage component 122 can be used to store various data, and the storage component 122 can include flash memory.

[0067] Figure 2 It is a structural block diagram of a screen driving board shown in an embodiment of the present application. The screen driving board can be Figure 1 the screen driving board in the display device shown. The screen driving board 20 includes: a timing control chip 21, a storage component 22, and a plurality of function controllers ( Figure 2 Taking the plurality of function controllers including function controller a, function controller b, and function controller c as an example for illustration, but not limited thereto), the timing control chip 21 is electrically connected to the storage component 22 and the plurality of function controllers respectively.

[0068] The storage component 22 includes a first partition q1, and the first partition q1 includes a plurality of function sub-partitions ( Figure 2 Taking the plurality of function sub-partitions including function sub-partition qa, function sub-partition qb, and function sub-partition qc as an example for illustration, but not limited thereto), the plurality of function sub-partitions (qa, qb, qc) correspond to the plurality of function controllers respectively, and the function sub-partitions (qa, qb, qc) store the programs (code) of the corresponding function controllers. For example, if the function sub-partition qa corresponds to the function controller a, then the program stored in the function sub-partition qa is the program of the function controller a.

[0069] The timing control chip 21 is used to write the program stored in the function sub-partition into the function controller corresponding to the function sub-partition to update the function controller.

[0070] Among them, the timing control chip 21 can obtain the programs of the above-mentioned multiple function controllers and store these programs in the respective function sub-partitions in the storage component 22. Furthermore, the timing control chip 21 can update the programs of the respective function controllers based on the programs stored in the respective function sub-partitions in the storage component 22.

[0071] In summary, the screen driving board provided by the embodiment of the present application divides multiple function sub-partitions in the storage component of the screen driving board. The function sub-partitions correspond to multiple function controllers in the screen driving board respectively, and the function sub-partitions store the programs of the corresponding function controllers. In this way, the timing control chip can write the programs stored in the function sub-partitions into the function controllers corresponding to the function sub-partitions, thereby achieving the effect of updating the programs of the function controllers in the screen driving board.

[0072] In addition, when the program is updated, the screen driving board does not need to remove the respective function controllers from the screen driving board. The effect of upgrading the programs of the function controllers in the screen driving board is achieved in the state of the whole machine after the screen driving board is installed in the display device, and the update efficiency of the programs of the function controllers in the screen driving board is improved.

[0073] Figure 3 It is a structural block diagram of another screen driving board shown in the embodiment of the present application. This screen driving board has made some adjustments on the basis of the screen driving board shown in Figure 2 the screen driving board shown.

[0074] Optionally, a first program check code is also stored in the function sub-partition. The first program check code in any one function sub-partition is the check code of the program stored in the function sub-partition. The first program check code can be generated by the timing control chip 21. Specifically, for any one function sub-partition qa, the timing control chip 21 can generate the first program check code a3 of the program a2 stored in the function sub-partition qa based on a preset algorithm. Among them, the preset algorithm can include various check code algorithms, such as the Cyclic Reduandancy Check (CRC) algorithm, etc.

[0075] The timing control chip 21 is used to generate a first real-time verification code based on the program written into the function controller corresponding to the function sub-partition after writing the program stored in the function sub-partition into the function controller. The timing control chip 21 can generate the first real-time verification code m12 based on the program written into the function controller according to the same preset algorithm. After that, the timing control chip 21 can confirm whether the update of the function controller is successful based on the first real-time verification code m12 and the first program verification code m11. Exemplarily, for any function sub-partition qa, the timing control chip 21 can generate the first program verification code a3 of the program a2 stored in the function sub-partition qa based on the preset algorithm. After that, after writing the program a2 stored in the function sub-partition qa into the function controller a corresponding to the function sub-partition, generate the first real-time verification code of the program written into the function controller according to the same preset algorithm, and confirm whether the update of the function controller a is successful based on the first real-time verification code and the first program verification code a3.

[0076] Specifically, the timing control chip 21 can confirm that the update of the function controller is successful when the first real-time verification code m12 is the same as the first program verification code m11, and confirm that the update of the function controller is not successful when the first real-time verification code m12 is different from the first program verification code m11. This is because when the timing control chip 21 writes the program stored in the function sub-partition q11 into the function controller corresponding to the function sub-partition, the program written into the function controller may be inconsistent with the program stored in the function sub-partition due to some reasons, which may cause the function controller to fail to operate normally. Therefore, by comparing the first real-time verification code m12 and the first program verification code m11, it can be known whether the update of the function controller is successful and used as a reference for the next operation. For example, when it is not successful, the timing control chip 21 can rewrite the program stored in the function sub-partition q11 into the function controller corresponding to the function sub-partition. After multiple failures, the timing control chip 21 can also send a signal to notify the operator to handle it.

[0077] Optionally, the function sub-partition q11 also stores a function controller identifier, and the function controller identifier is the identifier of the function controller corresponding to the program stored in the function sub-partition. Exemplarily, the function sub-partition qa stores a function controller identifier a1, and the function controller identifier a1 is the identifier of the function controller a corresponding to the function sub-partition qa. The timing control chip 21 can distinguish each function sub-partition based on the function controller identifier. Exemplarily, when updating multiple function controllers in sequence, the program stored in each function sub-partition can be obtained in sequence based on the function controller identifier, and the corresponding function controller can be updated.

[0078] Optionally, the first partition q1 further includes a preset sub-partition qx, and the program x1 of the timing control chip 21 is stored in the preset sub-partition qx. The storage component further includes a second partition q2, and the backup program x2 of the timing control chip 21 is stored in the second partition q2. The timing control chip 21 can update the program of the timing control chip 21 based on the program x1 of the timing control chip stored in the preset sub-partition qx of the first partition q1. That is, the timing control chip 21 can write the program x1 of the timing control chip stored in the preset sub-partition qx of the first partition q1 into the timing control chip 21 to update the program of the timing control chip 21. The backup program x2 can be used when the program of the timing control chip in the first partition is damaged or lost. The timing control chip can be started and the display panel can be lit based on the backup program x2. Optionally, the backup program x2 can be a program of a stable version of the timing control chip. Thus, when the program of the updated version of the timing control chip (such as the program x1 of the timing control chip stored in the preset sub-partition qx of the first partition q1) has a program failure and causes the timing control chip to be unable to drive the display panel to display, the timing control chip can be started based on the backup program x2 and perform other operations, such as updating the program of the function controller in the screen driving board and lighting the display panel, etc. Thus, the stability of the screen driving board can be improved.

[0079] Optionally, a second program check code x3 is further stored in the preset sub-partition qx, and the second program check code x3 is the check code of the program x1 of the timing control chip 21 stored in the preset sub-partition qx. The timing control chip 21 is used to generate a second real-time check code based on the program written into the timing control chip 21 after writing the program x1 of the timing control chip 21 into the timing control chip, and confirm whether the update of the timing control chip is successful based on the second real-time check code and the second program check code.

[0080] Wherein, the second program check code x3 is a check code generated by the timing control chip 21 based on a preset algorithm. The timing control chip 21 can generate a second real-time check code of the program written into the timing control chip 21 based on the preset algorithm, and verify whether the second program check code and the second real-time check code are the same. When they are the same, it can be confirmed that the upgrade of the program of the timing control chip 21 is successful. When they are different, it can be confirmed that the upgrade of the program of the timing control chip 21 is not successful. When it is not successful, it can be upgraded again or a notification signal can be sent.

[0081] Optionally, the first partition q1 further includes an identification sub-partition qy, in which a first identifier m1 is stored. The first identifier m1 is used to indicate whether the program of the timing control chip and the program of the function controller are stored in the storage component. The first identifier m1 can be a main flag. The timing control chip 21 can learn which programs are stored in the storage component 22 based on the first identifier m1, so as to perform update operations based on these programs. Please refer to Table 1:

[0082] Table 1

[0083]

[0084] Table 1 is a schematic partition table of a storage component in the screen driving board provided by the embodiment of the present application. This Table 1 includes four columns: partition, sector, content, and size. The partition can include a first partition q1 and a second partition q2. The first partition q1 further includes multiple sub-partitions, such as multiple function sub-partitions qa, qb, qc, qd, qe, qf. In addition, the first partition q1 further includes an identification sub-partition qy and a reserved sub-partition qg. In each function sub-partition, the first row can be the function controller identifier of the function controller corresponding to this function sub-partition, the third row can be the program of the function controller corresponding to this function sub-partition, and the second row can be the program check code of the program stored in the third row obtained according to a preset algorithm. In addition, the first partition can also include some other sub-partitions, such as a reserved sub-partition, which can be a reserved space for some other subsequent data. In addition, the first partition q1 can also include a version number sub-partition qg, which can be used to store the version number. The version number can include the version numbers of the programs stored in each function sub-partition, and the version number x1 of the program of the timing control chip 21 stored in the preset sub-partition qx. The timing control chip can determine the version of the program stored in the storage component based on this version number. For example, when the version of the program stored in the storage component is an updated version compared with the current versions of each controller, the program is updated. When the version of the program stored in the storage component is not an updated version, the program is not updated.

[0085] It can be seen that in the screen driving board provided by the embodiment of the present application, the programs of the timing control chip and the programs of multiple function controllers all have corresponding storage positions in the storage component, so as to avoid possible conflicts in the positions of the programs of controllers from different manufacturers in the storage component and the problem of program incompatibility.

[0086] Optionally, the first functional sub - partition among multiple functional sub - partitions includes 2 sectors. The first program check code, the program of the functional controller corresponding to the first functional sub - partition, and the first program check code of the program of the functional controller are stored in these 2 sectors. The first functional sub - partition is any one of the functional sub - partitions in the first partition. The structure shown in Table 1 above is that each functional sub - partition includes 2 sectors, but the embodiments of the present application do not limit this. That is, each functional sub - partition may also include other numbers of sectors, or the numbers of sectors included in different functional sub - partitions may also be different.

[0087] In summary, the screen driving board provided by the embodiments of the present application divides multiple functional sub - partitions in the storage component of the screen driving board. These functional sub - partitions correspond to multiple functional controllers in the screen driving board respectively, and the programs of the corresponding functional controllers are stored in these functional sub - partitions. In this way, the timing control chip can write the programs stored in the functional sub - partitions into the functional controllers corresponding to the functional sub - partitions, thereby achieving the effect of updating the programs of the functional controllers in the screen driving board.

[0088] In addition, when the program is updated, this screen driving board does not need to remove each functional controller from the screen driving board. It achieves the effect of upgrading the programs of the functional controllers in the screen driving board in the state of the whole machine after the screen driving board is installed in the display device, and improves the update efficiency of the programs of the functional controllers in the screen driving board.

[0089] Please refer to Figure 4 , Figure 4 which is a structural block diagram of a display device provided by the embodiments of the present application. The display device includes a display panel 41, a first controller 42, and a screen driving board 43.

[0090] The screen driving board 43 includes: a timing control chip 431, a storage component 432, and multiple functional controllers ( Figure 4 taking multiple functional controllers including functional controller a, functional controller b, and functional controller c as examples for illustration, but not limiting this). The timing control chip 431 is electrically connected to the storage component 432 and multiple functional controllers respectively.

[0091] The storage component 432 includes a first partition q1, and the first partition q1 includes multiple functional sub - partitions ( Figure 4Taking multiple functional sub - partitions including functional sub - partition qa, functional sub - partition qb, and functional sub - partition qc as examples for illustration (but not limited thereto), multiple functional sub - partitions (qa, qb, qc) respectively correspond to multiple functional controllers, and the functional sub - partitions (qa, qb, qc) store the programs of the corresponding functional controllers. The timing control chip 431 is used to write the programs stored in the functional sub - partitions into the functional controllers corresponding to the functional sub - partitions to update the functional controllers.

[0092] The first controller 42 is electrically connected to the screen driving board 43, and the screen driving board 43 is electrically connected to the display panel 41.

[0093] The first controller 42 may include an SOC. The first controller 42 can send instructions and some programs to the screen driving board 43. The timing control chip 431 in the screen driving board 43 can receive the instructions and some programs sent by the screen driving board 43.

[0094] In summary, for the display device provided by the embodiments of the present application, by dividing multiple functional sub - partitions in the storage component of the screen driving board, the functional sub - partitions respectively correspond to multiple functional controllers in the screen driving board, and the functional sub - partitions store the programs of the corresponding functional controllers. In this way, the timing control chip can write the programs stored in the functional sub - partitions into the functional controllers corresponding to the functional sub - partitions, thereby achieving the effect of updating the programs of the functional controllers in the screen driving board.

[0095] In addition, when the programs of the screen driving board need to be updated, the functional controllers do not need to be removed from the screen driving board. It realizes the effect of upgrading the programs of the functional controllers in the screen driving board in the state of the whole machine after the screen driving board is installed in the display device, and improves the update efficiency of the programs of the functional controllers in the screen driving board.

[0096] Optionally, the first controller 42 is used to provide the programs of multiple functional controllers on the screen driving board 43 to the screen driving board 43.

[0097] Optionally, the first controller 42 is used to send the first instruction among a preset plurality of instructions to the screen driving board 43, and the plurality of instructions respectively correspond to multiple operations.

[0098] The screen driving board 43 is used to receive the first instruction and execute the operation corresponding to the first instruction.

[0099] There may be a plurality of instructions pre - agreed between the screen driving board 43 and the first controller 42. After the first controller 42 sends one of the instructions to the screen driving board 43, the screen driving board 43 can execute the corresponding operation. Exemplarily, please refer to Table 2:

[0100] Table 2

[0101] Instruction Corresponding operation 1 Update based on the program in the functional sub - partition 2 Update based on the program in the preset sub - partition 3 Update based on the programs in the functional sub - partition and the preset sub - partition 4 Read the program check code in the functional sub - partition 5 Read the program check code in the preset sub - partition 6 Read the version number of the program stored in the storage component 7 Feedback information on whether the update is successful

[0102] Among them, instructions 1, 2, 3, 4, 5, 6, and 7 can be the serial numbers of instructions. The instructions can actually be preset data, such as hexadecimal data, etc. The embodiments of the present application do not limit this.

[0103] In this way, through some preset instructions, the operation of updating various controllers in the screen driving board 43 by the first controller 42 controlling the screen driving board 43 can be realized.

[0106] Step 502, when the first instruction indicates to update the program of the function controller, write the programs stored in multiple function sub - partitions into the function controllers corresponding to the function sub - partitions to update the function controllers.

[0107] In summary, for the method for updating a screen driving board provided by an embodiment of the present application, by dividing multiple function sub - partitions in the storage component of the screen driving board, the function sub - partitions respectively correspond to multiple function controllers in the screen driving board, and the function sub - partitions store the programs of the corresponding function controllers. In this way, the timing control chip can write the programs stored in the function sub - partitions into the function controllers corresponding to the function sub - partitions, thereby achieving the effect of updating the programs of the function controllers in the screen driving board.

[0108] In addition, when the screen driving board in the display device needs to update the program, it is not necessary to remove each function controller from the screen driving board. It realizes the effect of upgrading the programs of the function controllers in the screen driving board in the state of the whole machine after the screen driving board is installed in the display device, and improves the update efficiency of the programs of the function controllers in the screen driving board.

[0109] Figure 6 It is a flowchart of another method for updating a screen driving board provided by an embodiment of the present application. This method can be used for the timing control chip in the screen driving board provided by the above embodiment. This method includes the following steps:

[0110] Step 601, obtain a first instruction.

[0111] When applying the method provided in the embodiments of the present application, the timing control chip may receive a first instruction sent by a first controller in a display device, and this instruction may be used to instruct the timing control chip to update some controllers in the screen driving board.

[0112] In addition, before step 601, the timing control chip may obtain a program package provided by the first controller, and this program package may include the program of the timing control chip and the programs of multiple functional controllers in the screen driving board. After obtaining this program package, the timing control chip may store each program in the corresponding position in the storage component based on a preset storage location. For example, each program may be stored in the corresponding partition in the storage component based on the manner shown in Table 1. In the screen driving board provided by the embodiments of the present application, the program of the timing control chip and the programs of multiple functional controllers each have a corresponding storage location in the storage component, so as to avoid possible conflicts in the positions of the programs of controllers from different manufacturers in the storage component and the problem of program incompatibility.

[0113] The screen driving board applied in the embodiments of the present application may be Figure 3 the screen driving board shown as follows. The data stored in this screen driving board may be as shown in Table 1. When applying the method provided in the embodiments of the present application, the timing control chip may be started based on the backup program x2 of the timing control chip 21 stored in the second partition q2. Since this backup program x2 is a program of a stable version of the timing control chip, the timing control chip 21 can be started based on this backup program x2, which can improve the stability of the method provided in the embodiments of the present application. Of course, in some exemplary embodiments, the timing control chip 21 may also be started based on the program x1 of the timing control chip stored in the preset sub-partition qx of the first partition q1. The embodiments of the present application do not limit this.

[0114] Step 602: When the first instruction indicates to update the program of the functional controller, obtain the program stored in the nth functional sub-partition among multiple functional sub-partitions.

[0115] After receiving the first instruction, the timing control chip may determine the operation corresponding to the first instruction based on a pre-setting. For example, the data given in Table 2 in the above embodiments may be referred to to determine the operation corresponding to the instruction. The nth functional sub-partition may be any one of the multiple functional sub-partitions in the storage component.

[0116] In an exemplary embodiment, the functional sub - partition also stores a functional controller identifier, which is the identifier of the functional controller corresponding to the program stored in the functional sub - partition. The functional controller identifier can be a serial number, and the above n can be the functional controller identifier. There are x functional sub - partitions, and 1≤n<x. When applying the embodiment of the present application, the timing control chip can first update the functional controller corresponding to the first functional sub - partition among the x functional sub - partitions, that is, n = 1. Correspondingly, the timing control chip can determine the first functional sub - partition where the first functional controller identifier is located and obtain the program stored in the first functional sub - partition.

[0117] The step of obtaining the program stored in the functional sub - partition may refer to the step that the timing control chip can search in the storage component to determine the program.

[0118] In addition, the timing control chip can also read the first identifier. The first identifier can indicate whether the program of the timing control chip is stored in the storage component and whether the program of the functional controller is stored in the storage component. The first identifier can be a main flag. Before step 602, the timing control chip 21 can know which programs are stored in the storage component based on the first identifier, and when the first identifier indicates that the program of the functional controller is stored in the memory, execute step 602. In addition, the first identifier can also be used to indicate whether the program stored in the current storage component is an unfinished updated program. The timing control chip can execute step 602 when the program stored in the current storage component is an unfinished updated program, and stop the update step when the program stored in the current storage component is not an unfinished updated program (that is, the timing control chip has updated each controller based on the program stored in the storage component). Exemplarily, the first identifier may include the first instruction shown in Table 2 above, and the timing control chip can obtain the first instruction sent by the first controller by reading the first identifier.

[0119] Step 603: Write the program stored in the nth functional sub - partition into the nth functional controller corresponding to the nth functional sub - partition to update the nth functional controller.

[0120] The timing control chip can write the program stored in the nth functional sub - partition into the nth functional controller corresponding to the nth functional sub - partition to update the nth functional controller. When n = 1, it means that the timing control chip writes the program stored in the first functional sub - partition into the first functional controller corresponding to the first functional sub - partition to update the first functional controller.

[0121] Step 604: Generate a first real - time verification code based on the program written into the nth functional controller.

[0122] The timing control chip can generate a first real-time verification code for the program written to the nth function controller based on a preset algorithm. The preset algorithm can include various verification code algorithms, such as cyclic redundancy check algorithm, etc.

[0123] Step 605: Determine whether the first program verification code is consistent with the first real-time verification code. When they are consistent, execute step 606; when they are inconsistent, execute step 607.

[0124] The first program verification code is also stored in the functional sub-partition of the storage component in the screen driving board. The first program verification code is the verification code of the program stored in the functional sub-partition. The timing control chip can determine whether the first program verification code is consistent with the first real-time verification code. This is because when the timing control chip writes a program to the function controller, the program written to the function controller may be inconsistent with the program stored in the storage component due to various reasons. Therefore, the timing control chip can determine whether the program written to the function controller is consistent with the program stored in the storage component based on the two verification codes. When the first program verification code is consistent with the first real-time verification code, it can be considered that the program written to the function controller is consistent with the program stored in the storage component. When the first program verification code is inconsistent with the first real-time verification code, it can be considered that the program written to the function controller is inconsistent with the program stored in the storage component.

[0125] Step 606: Determine that the update of the first function controller is successful.

[0126] When the first program verification code is consistent with the first real-time verification code, the timing control chip can determine that the update of the first function controller is successful.

[0127] After step 606, n can be incremented by 1, and step 602 can be re-executed to update the next function controller. Exemplarily, if n = 1, then n + 1 = 2. The timing control chip can determine the second functional sub-partition where the identifier of the second function controller after the identifier of the first function controller is located, obtain the program stored in the second functional sub-partition, and then write the program stored in the second functional sub-partition to the second function controller corresponding to the second functional sub-partition to update the second function controller. Subsequently, the program written to the second function controller can also be verified based on step 604. The value after n + 1 can be used as the newly determined n, and at step 606, the newly determined n + 1 can be used, and step 602 can be re-executed. In this way, each function controller can be updated in sequence.

[0128] Step 607: When the first program verification code is inconsistent with the first real-time verification code, determine that the update of the nth function controller is unsuccessful.

[0129] When the first program check code is inconsistent with the first real-time check code, it indicates that the program written to the function controller is inconsistent with the program stored in the storage component. At this time, the timing control chip can determine that the update of the nth function controller is not successful. The timing control chip can re-execute step 603 to rewrite the program, or it can also provide the first controller with information indicating that the write fails, so that the operator can know and perform corresponding processing.

[0130] Step 608: When the first instruction indicates to update the program of the timing control chip, obtain the program of the timing control chip stored in the preset sub-partition.

[0131] The method provided by the embodiment of the present application can also update the timing control chip. When the first instruction indicates to update the program of the timing control chip, the timing control chip can obtain the program of the timing control chip stored in the preset sub-partition.

[0132] Step 609: Write the program of the timing control chip into the timing control chip.

[0133] The timing control chip can write the program of the timing control chip into the timing control chip to update the timing control chip.

[0134] In an exemplary embodiment, if a power failure or other faults occur when writing the program of the timing control chip into the timing control chip, resulting in damage to the program of the timing control chip, the timing control chip can be started by the backup program x2 of the timing control chip 21 stored in the second partition, and perform subsequent operations, such as lighting up the screen or updating some function controllers on the screen driving board. The backup program can be a program of a stable version of the timing control chip, so that the problem that the timing control chip is locked and abnormal in some unexpected situations (such as sudden power failure during the program upgrade process of the timing control chip) and thus unable to light up the display panel can be solved, improving the stability of the screen driving board.

[0135] Step 610: Generate a second real-time check code based on the program written into the timing control chip.

[0136] The timing control chip can generate a second real-time check code for the program written into the timing control chip based on a preset algorithm. The preset algorithm can be the same as or different from the algorithm for generating the first real-time check code in the above steps. The embodiment of the present application does not limit this.

[0137] Step 611: Determine whether the second program check code is consistent with the second real-time check code. If they are consistent, execute step 612; if they are inconsistent, execute step 613.

[0138] The second program check code is also stored in the preset sub - partition. The second program check code is the check code of the program of the timing control chip stored in the preset sub - partition. The timing control chip can determine whether the second program check code is consistent with the second real - time check code. This is because when the timing control chip writes the program into the timing control chip, due to various reasons, the program written into the timing control chip may be inconsistent with the program stored in the first partition. Therefore, the timing control chip can determine whether the program written into the timing control chip is consistent with the program stored in the first partition based on the two check codes. When the second program check code is consistent with the second real - time check code, it can be considered that the program written into the timing control chip is consistent with the program stored in the first partition. When the second program check code is inconsistent with the second real - time check code, it can be considered that the program written into the timing control chip is inconsistent with the program stored in the first partition.

[0139] Step 612: Determine that the update of the timing control chip is successful.

[0140] When the second program check code is consistent with the second real - time check code, it indicates that the program written into the timing control chip is consistent with the program stored in the first partition. The timing control chip can determine that the update of the timing control chip is successful.

[0141] Step 613: Determine that the update of the timing control chip is not successful. Execute step 609.

[0142] When the second program check code is inconsistent with the second real - time check code, it indicates that the program written into the timing control chip is inconsistent with the program stored in the first partition. The timing control chip can determine that the update of the timing control chip is not successful. At this time, the timing control chip can execute step 609 to write the program of the timing control chip into the timing control chip again. If the update of the timing control chip fails multiple times, an update failure instruction can also be sent to facilitate the operator to know the situation of the update failure.

[0143] It should be noted that the method provided in the embodiment of the present application can also update some controllers in the screen driving board, that is, the method can update at least one controller among multiple controllers (the multiple controllers can include a timing control chip and multiple function controllers) in the screen driving board.

[0144] After the programs of multiple controllers in the screen driving board are all updated by the timing control chip, the first identifier can be adjusted to indicate that the program stored in the current storage component is not a program with an unfinished update.

[0145] It should be noted that the above embodiments provide methods for updating the function controller and the timing control chip. The method for updating the screen driving board provided by the embodiments of the present application can update at least one of the function controller and the timing control chip through the methods provided by the above embodiments. For example, when the first instruction indicates to update only the program of the function controller, the program of the function controller can be updated separately in the manner of steps 602 to 607 above. When the first instruction indicates to update only the program of the timing control chip, the program of the timing control chip can be updated separately in the manner of steps 608 to 613 above. When the first instruction indicates to update the programs of the timing control chip and the function controller, the timing control chip and the function controller can be updated in the manner of steps 602 to 613 above.

[0146] In an exemplary embodiment, the method for updating the screen driving board provided by the embodiments of the present application can refer to Figure 7 , Figure 7 which is a flowchart of another method for updating the screen driving board provided by the embodiments of the present application. The method may include the following steps:

[0147] Step 701, the timing control chip starts through the backup program.

[0148] When applying the method provided by the embodiments of the present application, the timing control chip can start through the backup program. Since the backup program is a program of a stable version of the timing control chip, the timing control chip starts based on this backup program, which can improve the stability of the method provided by the embodiments of the present application.

[0149] Figure 7 The method shown may be a method with some adjustments based on the method shown in Figure 6 For related content, reference can be made to the method shown in Figure 6 The embodiments of the present application will not elaborate here.

[0150] Step 702, determine whether the update has been completed based on the first identifier. When it is not completed, execute step 703. When it is completed, end the update process.

[0151] After each update is completed, the timing control chip can adjust the first identifier to the state of completed update. Thus, when the timing control chip starts each update, it can first determine whether to perform the update based on the first identifier.

[0152] Step 703, determine whether to update the timing control chip separately. When updating the timing control chip separately, execute step 704. When not updating the timing control chip separately, execute step 708.

[0153] The first identifier can also be used to indicate the data for updating those controllers. For example, the first identifier can indicate to update only the timing control chip, or the first identifier can indicate to update only the function controller, or the first identifier can indicate to update both the timing control chip and the function controller. Among them, when the first identifier indicates to update only the timing control chip, the timing control chip can determine that it is the case of updating the timing control chip alone, and the timing control chip can determine that the remaining cases are not the cases of updating the timing control chip alone.

[0154] Step 704: Obtain the program of the timing control chip stored in the preset sub-partition.

[0155] This step can refer to step 608 in the above embodiment, and details are not described herein again in the embodiments of the present application.

[0156] Step 705: Write the program of the timing control chip stored in the preset sub-partition into the timing control chip.

[0157] This step can refer to step 609 in the above embodiment, and details are not described herein again in the embodiments of the present application.

[0158] In this step, the timing control chip can generate a second real-time check code based on the program written into the timing control chip.

[0159] Step 706: Determine whether the second program check code is consistent with the second real-time check code. When they are consistent, execute step 707; when they are inconsistent, execute step 705.

[0160] This step can refer to step 611 in the above embodiment, and details are not described herein again in the embodiments of the present application.

[0161] Step 707: Determine that the update of the timing control chip is successful.

[0162] When the second program check code is consistent with the second real-time check code, it indicates that the program written into the timing control chip is consistent with the program stored in the first partition, and the timing control chip can determine that the update of the timing control chip is successful.

[0163] Step 708: Determine whether to update the timing control chip. When yes, execute step 709; when no, execute step 712.

[0164] The timing control chip can determine not to update the timing control chip when the first identifier indicates to update only the function controller, and can determine to update the timing control chip when the first identifier indicates to update both the timing control chip and the function controller.

[0165] Step 709: Obtain the program of the timing control chip stored in the preset sub-partition.

[0166] This step may refer to step 608 in the above-mentioned embodiment, and details are not described herein again in the embodiments of the present application.

[0167] Step 710: Write the program of the timing control chip stored in the preset sub-partition into the timing control chip.

[0168] This step may refer to step 609 in the above-mentioned embodiment, and details are not described herein again in the embodiments of the present application.

[0169] In this step, the timing control chip may generate a second real-time verification code based on the program written into the timing control chip.

[0170] Step 711: Determine whether the second program verification code is consistent with the second real-time verification code. When they are consistent, execute step 712; when they are inconsistent, execute step 710.

[0171] This step may refer to step 611 in the above-mentioned embodiment, and details are not described herein again in the embodiments of the present application.

[0172] Step 712: Obtain the serial number of the current function controller.

[0173] The serial number of the current function controller may be 0 (or may also be 1) in the initial state. Subsequently, each time the program of a function controller is updated (when it is determined to be yes in step 716), the serial number of the function controller can be incremented by 1. Then, when step 712 is executed next time, the obtained serial number of the current function controller is 1, and so on.

[0174] Step 713: Determine whether the serial number of the current function controller is the preset maximum value. When it is not, execute step 714; when it is, end the update.

[0175] The preset maximum value is equal to the maximum number of function controllers in the screen driving board. For example, it can be 5, 6, 7, 8, 9, 10... The embodiments of the present application do not limit this. When the serial number of the current function controller is the preset maximum value, it indicates that the programs of all function controllers on the screen driving board have been updated, and at this time, the update can be ended. When the serial number of the current function controller is not the preset maximum value, it indicates that there are still programs of function controllers on the screen driving board that have not been updated.

[0176] Step 714: Obtain the program stored in the nth functional sub-partition.

[0177] n = the serial number of the current function controller. This step may refer to step 602 in the above-mentioned embodiment, and details are not described herein again in the embodiments of the present application.

[0178] Step 715: Write the program stored in the nth functional sub - partition into the nth functional controller corresponding to the nth functional sub - partition.

[0179] This step can refer to step 603 in the above - mentioned embodiment, and the embodiments of the present application will not elaborate here.

[0180] In this step, the timing control chip can generate a first real - time check code based on the program written into the nth functional controller.

[0181] Step 716: Determine whether the first program check code is consistent with the first real - time check code. When they are consistent, increment the functional controller number by 1 and execute step 712. When they are inconsistent, execute step 715.

[0182] When the first program check code is consistent with the first real - time check code, it indicates that the update of the program for the functional controller this time is successful. At this time, the program of the next functional controller can be updated, that is, the functional controller number can be incremented by 1 and step 712 is executed. In step 712, the number of the current functional controller obtained by the timing control chip is the number of the next functional controller. Through such a cycle, the programs of each functional controller can be updated.

[0183] In addition, this step can also refer to step 605 in the above - mentioned embodiment, and the embodiments of the present application will not elaborate here.

[0184] In summary, for the update method of the screen driving board provided by the embodiments of the present application, by dividing multiple functional sub - partitions in the storage component of the screen driving board, these functional sub - partitions respectively correspond to multiple functional controllers in the screen driving board, and the functional sub - partitions store the programs of the corresponding functional controllers. In this way, the timing control chip can write the programs stored in the functional sub - partitions into the functional controllers corresponding to the functional sub - partitions, thereby achieving the effect of updating the programs of the functional controllers in the screen driving board.

[0185] In addition, when the screen driving board in the display device needs to update the program, it is not necessary to remove each functional controller from the screen driving board. It realizes the effect of upgrading the programs of the functional controllers in the screen driving board in the state of the whole machine after the screen driving board is installed in the display device, and improves the update efficiency of the programs of the functional controllers in the screen driving board.
