[0002] Currently, most large and medium-sized LCD display products adopt a solution driven by multiple source driver chips. To ensure the stable supply of source driver chips, multiple mutually compatible chips are used in the same project. In the related art, multiple chips can only be mutually compatible in terms of pin connection and cannot be compatible in terms of code, which makes it easy to have problems of code configuration confusion during the production process. Summary of the Invention

[0003] Embodiments of the present invention provide a configuration method, a configuration device, a display module, a timing control chip, and a computer-readable storage medium.

[0004] Embodiments of the present invention provide a configuration method, and the configuration method includes: sending a request message to a chip, where the request message is used to request to determine the chip type of the chip; receiving a return message, where the return message is the message sent by the chip according to the request message, and the return message includes the chip type of the chip; sending the code corresponding to the chip type to the chip according to the return message to configure the chip according to the code.

[0005] In this way, a request message is sent to the chip, the chip type of the chip is determined according to the return message returned by the chip, and then the code corresponding to the chip type is sent to the chip to accurately complete the configuration of the code, avoiding the problem of code configuration confusion between multiple chips.

[0006] In some embodiments, the number of the chips is multiple, each chip is provided with a unique serial number, the chip includes a target chip, the request message includes the serial number of the target chip, and receiving the return message includes: receiving the return message sent by the target chip, where the return message includes the chip type of the target chip.

[0007] In this way, when the request message is received, only the target chip will send a return message, and other chips will not send a return message, thereby avoiding the problem that the chip type cannot be matched with the chip due to receiving the chip types returned by multiple chips at the same time, and avoiding the problem of possible configuration confusion even when the chip type is received.

[0008] In some embodiments, the request signal includes an indication field, and the indication field stores the serial number of the target chip.

[0009] In this way, the target chip serial number can be determined according to the content of the indication field, so as to determine the chip for which the request information requests to determine the chip type.

[0010] In some embodiments, the request information includes an operation field and an address field. The operation field stores read operation information, and the address field stores a read byte address, which is the address where the target chip stores the chip type. When the target chip receives the request information, the target chip reads the address storing the chip type according to the read operation information to obtain the chip type, and sends a return information including the chip type.

[0011] In this way, according to the content stored in the operation field and the address field in the request information, the target chip can determine the operation it needs to perform and the content of the operation to be executed, that is, the target chip reads its own chip type according to the read byte address and returns a return information with the chip type to implement the transmission of the chip type.

[0012] In some embodiments, the return information includes a type code, and different chip types correspond to different type codes. Sending the code corresponding to the chip type to the chip according to the return information includes: determining the chip type of the chip according to the type code of the return information; sending the code corresponding to the chip type.

[0013] In this way, the chip type of the chip can be determined through the type code in the return information, and the corresponding code can be determined according to the chip type and sent to the chip to implement the configuration of the chip.

[0014] In some embodiments, the encoding forms of the request information and the return information are the same.

[0015] In this way, since the encoding forms of the request information and the return information are the same, the request information and the return information can be transmitted on the same transmission line and the same interface, and the transmission directions of the request information and the return information are opposite, that is, bidirectional transmission.

[0016] In some embodiments, after the configuration of the chip is completed, the chip transmits display data. After sending the code corresponding to the chip type to the chip according to the return information, the configuration method includes: during the transmission of the display data, if the chip has an abnormality, re-enter the step of sending request information to the chip.

[0017] In this way, when the chip has an abnormality, it is considered that the chip configuration is incorrect, then the chip type of the chip is re-determined, and the configuration code is configured according to the newly determined chip type, so as to adaptively correct the configuration error and improve the configuration automation ability.

[0018] An embodiment of the present invention provides a configuration device, which includes a first sending module, a receiving module, and a second sending module. The first sending module is configured to send a request message to a chip, and the request message is used to request to determine the chip type of the chip; the receiving module is configured to receive a return message, the return message is the message sent by the chip according to the request message, and the return message includes the chip type of the chip; the second sending module is configured to send the code corresponding to the chip type to the chip according to the return message, so as to configure the chip according to the code.

[0019] In this way, a request message is sent to the chip, the chip type of the chip is determined according to the return message returned by the chip, and then the code corresponding to the chip type is sent to the chip, so as to accurately complete the configuration of the code and avoid the problem of chaotic configuration of different codes among multiple chips.

[0020] An embodiment of the present invention provides a display module, which includes a source driver chip and a timing control chip. The source driver chip is configured to output a source signal, and the timing control chip is connected to the source driver chip; the timing control chip is configured to: send a request message to the chip, the request message is used to request to determine the chip type of the source driver chip; receive a return message, the return message is the message sent by the source driver chip according to the request message, and the return message includes the chip type of the source driver chip; send the code corresponding to the chip type to the source driver chip according to the return message, so as to configure the source driver chip according to the code.

[0021] In this way, a request message is sent to the source driver chip, the chip type of the source driver chip is determined according to the return message returned by the source driver chip, and then the code corresponding to the chip type is sent to the source driver chip, so as to accurately complete the configuration of the code and avoid the problem of chaotic configuration of different codes among multiple source driver chips.

[0023] In this way, when the request message is received, only the target chip will send a return message, and other source driver chips will not send return messages, so as to avoid the problem that the chip type cannot be matched with the source driver chip due to receiving the chip types returned by multiple source driver chips at the same time, and avoid the problem of possible configuration chaos even if the chip type is received.

[0024] In some embodiments, the returned information includes a type code, and different chip types correspond to different type codes. The timing control chip is further configured to determine the chip type of the source driver chip according to the type code of the returned information, and send the code corresponding to the chip type.

[0025] In this way, the chip type of the source driver chip can be determined through the type code in the returned information, and the corresponding code can be determined according to the chip type, and the corresponding code is sent to the source driver chip to implement the configuration of the source driver chip.

[0026] In some embodiments, after the configuration of the chip is completed, the chip transmits display data. During the transmission of the display data, if the source driver chip malfunctions, the timing control chip is configured to resend a request message to the source driver chip.

[0027] In this way, when the source driver chip malfunctions, it is considered that the configuration of the source driver chip is incorrect, and then the chip type of the source driver chip is re-determined, and the code is configured according to the newly determined chip type, so as to adaptively correct the configuration error and improve the configuration automation ability.

[0044] The following details the embodiments of the present invention. The embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0045] Currently, most large and medium-sized LCD display products adopt a solution driven by multiple source driver chips. To ensure the stable supply of source driver chips, multiple mutually compatible chips are used in the same project. In the related art, multiple chips can only be mutually compatible in terms of pin connections and are not code-compatible, resulting in the problem of code configuration confusion easily occurring during the production process.

[0046] Please refer to Figure 1 , an embodiment of the present invention provides a configuration method, and the configuration method includes:

[0047] 01: Send a request message to the chip, and the request message is used to request to determine the chip type of the chip;

[0048] 02: Receive the return information, where the return information is the information sent by the chip according to the request information, and the return information includes the chip type of the chip.

[0049] 03: Send the code corresponding to the chip type to the chip according to the return information to configure the chip according to the code.

[0050] Specifically, please refer to Figure 2 , the configuration method of the embodiment of the present invention can be implemented by the configuration device 100 of the embodiment of the present invention. The configuration device 100 includes a first sending module 10, a receiving module 20, and a second sending module 30. The first sending module 10 can be used to send request information to the chip, and the request information is used to request to determine the chip type of the chip; the receiving module 20 can be used to receive the return information, where the return information is the information sent by the chip according to the request information, and the return information includes the chip type of the chip; the second sending module 30 can be used to send the code corresponding to the chip type to the chip according to the return information to configure the chip according to the code.

[0051] Among them, the configuration device 100 can be a Timing Controller (TCON) or a System on Chip (SOC). In this embodiment, the configuration device 100 is taken as an example of the TCON for description. The chip can be a Source IC, and the Source IC is used to transmit display data to control pixel display. The chip type can be the model of the chip. Data can be returned between the TCON and the Source IC through a PTP interface. Existing transmission lines can be used for data return, such as BBC (Bidirectional Command Channel), or a dedicated bidirectional transmission line can be added for data return. The TCON is used as the transmitter TX, and the Source IC is used as the receiver RX. The TCON sends the request information to the Source IC through the transmission line to request the chip model of the Source IC, and the Source IC sends its own chip model back to the TCON through the return information; the TCON sends multiple request information to request the chip models of all Source ICs until the chip models of all Source ICs have been determined. Then, the TCON determines the code applicable to the Source IC according to the chip models in the received return information. The codes corresponding to all types of chips are pre-stored in the flash. The TCON retrieves the code from the flash and sends the code to the Source IC to configure the Source IC with the code, realizing that the TCON or SOC adaptively determines the code for configuring the Source IC without manual setting, avoiding display defects caused by incorrect manual configuration; in addition, for different Source ICs, the same TCON board or SOC can be used, reducing the types of TCON or SOC boards and lowering the cost.

[0052] In this way, a request message is sent to the chip, and the chip type of the chip is determined according to the returned message returned by the chip. Then, a code corresponding to the chip type is sent to the chip to accurately complete the configuration of the code adaptively, avoiding the problem of confusion in different code configurations among multiple chips.

[0053] Please refer to Figure 3 , in some embodiments, the number of chips is multiple, each chip is provided with a unique serial number, the chip includes a target chip, the request message includes the serial number of the target chip, and step 02 (receiving the returned message) includes:

[0054] 021: Receive the returned message sent by the target chip, and the returned message contains the chip type of the target chip.

[0055] Specifically, please refer to Figure 4 , step 021 can be implemented by the receiving sub-module 21 of the receiving module 20. That is to say, the receiving sub-module 21 can be used to receive the returned message sent by the target chip, and the returned message contains the chip type of the target chip.

[0056] Wherein, a unique serial number ID is set for each source driving chip, that is, the serial number IDs do not repeat, one source driving chip corresponds to one serial number ID, and the serial number ID can be used to refer to the corresponding source driving chip. The target chip is the chip whose chip type needs to be determined by this request message. When the source driving chip receives the request message, it first compares the signal ID in the request message with its own serial number ID to determine whether it is the target chip of the request message. When it determines that it is the target chip of the request message, the source driving chip transmits its own chip type back to the TCON through the returned message; when it determines that it is not the target chip of the request message, the source driving chip does not send the returned message. In addition, after receiving the request message, the target chip will send a return message after the preparation time and before the return timeout. During the preparation time, the target chip processes the request message. If the target chip still does not send the returned message before the return timeout, that is, the TCON does not receive the returned message before the return timeout, the TCON resends a request message until the returned message is received. Any source driving chip cannot ignore any request message and will determine whether it is the target chip of the request message according to the serial number ID inside the request message.

[0057] In this way, when the request message is received, only the target chip will send the returned message, and other chips will not send the returned message, thereby avoiding the problem that the chip type cannot be matched with the chip due to receiving the chip types returned by multiple chips at the same time, and avoiding the problem that configuration confusion may occur even if the chip type is received.

[0058] In some embodiments, the request signal includes an indication field that stores the serial number of the target chip.

[0059] Specifically, the indication field of the request signal is in the main body of the request signal. In the main body of the request information, the 1st to 5th bits in one byte can be used to store the serial number ID of the target chip, that is, 32 serial numbers can be stored. Multiple bytes or other bits of one byte can also be used for storage, which is not limited here. In one embodiment, a 2Byte data is used to define the request instruction, and Byte0[4:0] is defined as the indication field, that is, the 1st to 5th bits of the first byte are the indication field.

[0060] In this way, the serial number of the target chip can be determined according to the content of the indication field, so as to determine the chip for which the request information requests to determine the chip type.

[0061] In some embodiments, the request information includes an operation field and an address field. The operation field stores read operation information, and the address field stores the read byte address. The read byte address is the address where the target chip stores the chip type. When the target chip receives the request information, the target chip reads the address where the chip type is stored according to the read operation information to obtain the chip type, and sends a return information containing the chip type.

[0062] Specifically, when the target chip receives the request information, it determines that it needs to perform a read operation according to the read operation information stored in the operation field, determines the address to be read according to the read byte address in the address field, reads the content in this address, and transmits it back to the TCON through the return information. The address of the source driver chip determined by the read byte address is the address used to store the chip type of the source driver chip. Therefore, reading the content in the read byte address can read the chip type, and the chip type is sent back to the TCON through the return information to realize the return of the chip type. In addition, the operation field is included in the control instruction for the TCON to send the code, and the operation field stores write operation information. When the target chip receives the control instruction, it determines to perform a write operation according to the write operation information and performs code writing. In one embodiment, the main body of the request information uses two bytes to define the request instruction, where Byte 0[5] is set to b1 to indicate a read operation, and Byte 0[7:6] and Byte 1[7:0] are set to the read byte address, that is, the sixth bit of the first byte is the operation field, and the seventh and eighth bits of the first byte and the first to eighth bits of the second byte are the address field.

[0063] In this way, according to the content stored in the operation field and the address field in the request information, the target chip can determine the operation it needs to perform and the content of the operation to be executed, that is, the target chip reads its own chip type according to the read byte address and returns the return information with the chip type to realize the return of the chip type.

[0064] Please refer to Figure 5 In some embodiments, the returned information includes a type code, and different chip types correspond to different type codes. Step 03 (sending the code corresponding to the chip type to the chip according to the returned information) includes:

[0065] 031: Determine the chip type of the chip according to the type code of the returned information;

[0066] 032: Send the code corresponding to the chip type.

[0067] Specifically, please refer to Figure 6 In, step 031 can be implemented by the determination sub-module 31 of the second sending module 30, and step 032 can be implemented by the sending sub-module 32 of the second sending module 30. That is to say, the determination sub-module 31 can be used to determine the chip type of the chip according to the type code of the returned information; the sending sub-module 32 can be used to send the code corresponding to the chip type.

[0068] Among them, different models of chips are encoded, and all chips are encoded in the same encoding method, and the encoding is stored in the chip before leaving the factory for distinction. Please refer to Table 1. For example, 4 types of chips are respectively encoded as 00, 01, 10, and 11. A type number corresponds to one model of chip, that is, the model of the chip can be determined according to the type code. The lower two bits of one byte of the main body part of the returned information can be used to store the chip type. TCON can know the model of the chip according to the type code stored in the returned information, retrieve the corresponding code from the flash, and send the code to the chip. If more chips need to be distinguished, more bits of the main body part of the returned information can be taken to store the chip type to identify more chips.

[0070] Table 1

[0071] In this way, the chip type of the chip can be determined through the type code in the returned information, and the corresponding code can be determined according to the chip type, and the corresponding code is sent to the chip to implement the configuration of the chip.

[0072] In some embodiments, the encoding forms of the request information and the returned information are the same.

[0073] Specifically, since the request information and the returned information are both transmitted on the same transmission line, the encoding forms of the request information and the returned information are the same. Please refer to Figure 7, in one embodiment, the rising edge of the clock corresponds to data 0, and the falling edge of the clock corresponds to data 1. T represents 1 bit, and the time of each bit is defined as 2 μs (bandwidth 500 kbps); both the request information and the return information include a preamble (A), a start identifier (B), a transmission data body (C), and an end identifier (D). Among them, the preamble contains at least 8 bits of data b0; the start identifier includes 2 bits of data b0; the end identifier remains high for at least 2 bits of time; the transmission body includes various types of information. For example, the transmission body of the request information includes at least an indication field, an operation field, an address field, etc., and the transmission body of the return information includes at least a type code.

[0074] In this way, the encoding forms of the request information and the return information are the same, which enables the request information and the return information to be transmitted on the same transmission line and the same interface, and the transmission directions of the request information and the return information are opposite, that is, bidirectional transmission.

[0075] Please refer to Figure 8 , in some embodiments, after the chip is configured, the chip transmits display data. After step 03 (sending the code corresponding to the chip type to the chip according to the return information), the configuration method includes:

[0076] 04: During the transmission of the display data, if an abnormality occurs in the chip, re-enter step 01 (sending a request message to the chip).

[0077] Specifically, please refer to Figure 9 , step 04 can be implemented by the repetition module 40 of the configuration device 100. That is to say, the repetition module 40 can be used to re-enter step 01 (sending a request message to the chip) if an abnormality occurs in the chip during the transmission of the display data.

[0078] Among them, after the chip is configured, the display data is started to be transmitted for display. If an abnormality occurs in the chip during the transmission of the display data, the chip configuration is incorrect, and steps 01 to 03 are re-entered. That is, the TCON re-determines the chip type of the chip and re-configures the code for the chip to adaptively correct errors and reduce the chip configuration error rate. In one embodiment, during the transmission of the display data, in the case of a receiving end lock exception, the feedback loss-of-lock signal is triggered, the TCON determines that the chip is abnormal, re-determines the chip type of the chip, and re-configures the code for the chip.

[0079] In this way, when an abnormality occurs in the chip, it is considered that the chip configuration is incorrect, and then the chip type of the chip is re-determined, and the code is configured according to the newly determined chip type, so as to adaptively correct the configuration error and improve the configuration automation ability.

[0080] An embodiment of the present invention provides a display module, including a source driver chip and a timing control chip. The source driver chip is configured to output a source signal, and the timing control chip is connected to the source driver chip. The timing control chip is used to: send a request message to the chip, where the request message is used to request to determine the chip type of the source driver chip; receive a return message, where the return message is the message sent by the source driver chip according to the request message, and the return message includes the chip type of the source driver chip; send a code corresponding to the chip type to the source driver chip according to the return message, so as to configure the source driver chip according to the code.

[0081] Specifically, please refer to Figure 10 , one TCON is connected to multiple source driver chips (Source Driver IC). Among them, FPC is a flexible printed circuit board (Flexible Printed Circuit), XPCB is a PCB (Printed Circuit Board, printed circuit board) arranged in the X direction, and the source driver chip can also be arranged on the FPC. When the display module is powered on or reset, data is transmitted between the chip and the TCON or SOC to determine the chip type of the chip, and the chip is configured by calling the code from the flash according to the determined chip type. The display module further includes a liquid crystal display panel (LCD). The liquid crystal display panel includes multiple source lines and multiple gate lines. The multiple source lines and multiple gate lines define a plurality of sub-pixels arranged in an array. The multiple source driver chips are respectively connected to the LCD and used to output source signals to the multiple source lines. The TCON and the multiple source driver chips are respectively connected through data lines on the FPC and the XPCB. The TCON is connected to the flash and calls the code in the flash to be transmitted to the source driver chip through the data line and configure the source driver chip.

[0082] In this way, a request message is sent to the chip, the chip type of the chip is determined according to the return message returned by the chip, and then a code corresponding to the chip type is sent to the chip to accurately complete the configuration of the code, avoiding the problem of confusion in different code configurations among multiple chips.
