In the process of driving the panel, especially when signals in the high-speed differential signal lines are transmitted over a long distance, signal attenuation is very severe, and different transmission parameter configuration information is usually required to be set for source driver chips at different positions to avoid signal distortion transmitted in the high-speed differential signal lines, where the transmission parameter configuration information may include configuration of parameters such as pre-emphasis parameters and signal swing.

Referring to fig. 3, fig. 3 is a flowchart of a method for determining transmission parameter configuration information according to an embodiment of the present invention, where the method is applied to a sending end, the sending end is respectively connected to a receiving end through a first signal line and a second signal line, a signal transmission rate of the second signal line is greater than a signal transmission rate of the first signal line, the sending end may be the timing controller shown in fig. 1, and as shown in fig. 3, the method includes:

step 301, sending a time reference signal to a receiving end through a first signal line, where the time reference signal has a plurality of time intervals.

Step 302, sending a test signal through a second signal line while sending the time reference signal.

The test signal received by the receiving end comprises a plurality of sub-test signals which are in one-to-one correspondence with a plurality of time intervals, and the plurality of sub-test signals are respectively obtained by transmitting the same initial test signal between the transmitting end and the receiving end based on different transmission parameter configuration information.

Step 303, receiving the identifier of the target transmission parameter configuration information sent by the receiving end through the first signal line.

The target transmission parameter configuration information is transmission parameter configuration information corresponding to a target time interval, and the target time interval is a time interval corresponding to a sub-test signal with the highest transmission accuracy determined in a plurality of time intervals on the basis of each received sub-test signal by the receiving end.

Referring to fig. 4-1, fig. 4-1 is a schematic flow chart of a method for determining transmission parameter configuration information according to an embodiment of the present invention, where the method is applied in the application environment shown in fig. 1, and a transmitting end is used as a timing controller and a receiving end is used as a source driver chip, to explain the method, the method includes:

step 401, the timing controller sends basic parameter configuration information to the source driver chip.

The basic parameter configuration information is information that each source driving chip needs to be configured before the time schedule controller sends the test signal to the source driving chips through the second signal line, so that the data of each source driving chip after being electrified can be uniformly configured. The basic parameter configuration information includes configuration information of various parameters, which are parameters that have been determined after the entire panel driving architecture is determined, regardless of the actual transmission path and signal attenuation. For example, the basic parameter configuration information may include information such as the number of second signal lines (also referred to as the number of high-speed channels), a transmission rate (i.e., a transmission rate of data on each signal line), and the number of pixels.

Optionally, the basic parameter configuration information may be carried in a configuration instruction sent by the timing controller to the source driver chip through the first signal line, and formats of instructions transmitted between the timing controller and the source driver chip may be the same, each instruction transmitted on the first signal line may include a preamble, a start identifier, a data bit (also referred to as a transmission body), and a stop identifier, which are sequentially arranged, and a schematic diagram of the format of the instruction refers to fig. 4-2.

The receiving end (the timing controller or the source driving chip) of the instruction can perform clock and phase adjustment according to the content of the preamble when detecting that the preamble transmission exists on the first signal line, the clock and phase adjustment means that the clock is kept consistent with the clock of the sending end of the instruction (namely, the instruction containing the preamble), the phase is the same as that of the sending end of the instruction, the receiving end of the instruction adjusts the clock and the phase in the process of receiving the preamble, and after the preamble transmission is finished, the clock and phase adjustment is finished. The start mark is used for indicating the start of data transmission, the data bit is used for carrying data such as basic parameter configuration information, and the end mark is used for indicating the end of data transmission.

And step 402, the source driving chip performs basic parameter configuration according to the basic parameter configuration information.

After receiving the basic parameter configuration information sent by the timing controller, the source driver chip may perform basic parameter configuration according to the basic parameter configuration information, where the basic parameter configuration process is an initialization process of the basic information of the second signal line, and since the second signal line may be a high-speed signal line, the basic parameter configuration process is also referred to as an initialization process when a connection is established in a high-speed channel.

For example, when the basic parameter configuration information includes the number of second signal lines connected to each source driver chip, the source driver chip stores the number of second signal lines connected to the source driver chip, and performs preset configuration on the number of second signal lines according to the number of second signal lines included in the basic parameter configuration information, so as to receive the test signal using the configured second signal lines. Note that, when the second signal line is a differential signal line, one second signal line is actually a signal line composed of two sub-signal lines. When the basic parameter configuration information includes a transmission rate, the transmission rate is used for informing the source driver chip of the transmission rate of the signal to be transmitted, so that the source driver chip can accurately work at the appointed transmission rate.

It should be noted that, in a general case, one source driver chip is connected to one second signal line, but in some special scenarios, one second signal line may not meet the transmission requirement of the source driver chip, so that one source driver chip may also be connected to at least two second signal lines according to the situation, in practical application, the basic parameter configuration information includes the number of the second signal lines connected to each source driver chip, but when the number of the second signal lines connected to all the source driver chips is the same, the basic parameter configuration information may carry the number of one second signal line, which indicates that each source driver chip is configured according to the number, and if the carried number is 1, that is, each source driver chip is connected to 1 second signal line.

The basic parameter configuration information in step 402 is a parameter that has been determined after the determination of the entire panel driving architecture, and is not related to factors such as an actual transmission path, but includes some transmission parameters during the signal transmission process, and these transmission parameters are affected by factors such as the actual transmission path, so before transmitting a signal related to display, configuration information of the transmission parameters needs to be determined to ensure the correctness of the transmitted signal.

In the embodiment of the invention, the time reference signals with a plurality of time intervals are transmitted on the first signal line through the timing controller and the source driving chip at the same time, and the test signals are transmitted on the second signal line, so that the source driving chip can determine the target time interval corresponding to the sub-test signal with the highest transmission accuracy according to the plurality of sub-test signals which are in one-to-one correspondence with the plurality of time intervals, and determine the target transmission parameter configuration information corresponding to the target time interval as the configuration information of the transmission parameters, so that the timing controller and the source driving chip can transmit signals based on the target transmission parameter configuration information. Please refer to steps 403 to 407 below in the process of determining the configuration information of the transmission parameters.

In step 403, the timing controller sends a time reference signal to the source driver chip through the first signal line.

Accordingly, the source driving chip receives the time reference signal transmitted from the timing controller through the first signal line while the timing controller transmits the time reference signal to the source driving signal.

To ensure that the source driving signal can effectively recognize the timing reference signal, please continue to refer to fig. 4-2, a transition edge may be generated between the first bit of the timing reference signal and the end flag (i.e., the first bit of the timing reference signal is different from the last bit of the end flag, e.g., the first bit of the timing reference signal is 1, and the last bit of the end flag is 0). Meanwhile, the last bit of the time reference signal may generate a transition edge with the first bit of the next signal. Through the jumping edge, the source driving chip can distinguish the time reference signal from other signals conveniently.

The time reference signal has a plurality of time intervals, each time interval having a distinct distinguishing identity. The plurality of time intervals are used for providing a time reference function for the source driving chip when the source driving chip receives a plurality of signals so as to distinguish the signals received in different time periods. Optionally, in the time reference signal, a first bit of a later time interval may generate a jumping edge with a last bit of a previous time interval, and the source driver chip may distinguish a plurality of time intervals in the time reference signal through the jumping edge, so as to implement effective identification of data. Alternatively, a clock signal having a plurality of cycles may be employed as the time reference signal, and each time interval may include at least one cycle of the clock signal. Because the clock signal has fixed clock frequency, when the clock signal is used as a time reference signal, the reference function of the time interval can be simply and accurately realized.

Step 404, the timing controller sends the test signal through the second signal line while sending the time reference signal.

When the time sequence controller sends the time reference signal through the first signal wire, the time sequence controller also sends a test signal through the second signal wire, and correspondingly, the source driving chip also receives the test signal sent by the time sequence controller through the second signal wire while receiving the time reference signal. The received test signals comprise a plurality of sub-test signals which are in one-to-one correspondence with a plurality of time intervals, the sub-test signals are obtained by transmitting the same initial test signal between the time schedule controller and the source electrode driving chip based on different transmission parameter configuration information, each sub-test signal corresponds to one time interval, and according to the reference effect of the time intervals, the source electrode driving chip can distinguish the sub-test signals and further receive the sub-test signals carrying different information.

The different transmission parameter configuration information is obtained by performing different parameter configurations for the same set of transmission parameters, and since the transmission process is performed by sending a signal from a sending end (a timing controller) and receiving the signal from a receiving end (i.e., a source driver chip), the same set of transmission parameters may include: originating parameters and terminating parameters, and thus, the different transmission parameter configuration information may include: and carrying out parameter configuration on the parameters of the sending end at the sending end and carrying out parameter configuration on the parameters of the receiving end at the receiving end.

Optionally, when the sending end performs parameter configuration for the sending end parameter, as shown in fig. 5-1, a process of the timing controller sending the test signal through the second signal line may include:

in step 404a1, the timing controller obtains the corresponding relationship between a plurality of preset time intervals and different transmission parameter configuration information.

The corresponding relationship is recorded with transmission parameter configuration information of the originating parameter corresponding to each time interval, and the originating parameter may include parameters such as signal swing amplitude and signal pre-emphasis parameter. The signal swing refers to the difference between the maximum value and the minimum value of the signal, and when the signal swing is larger, the fluctuation of the signal is more obvious, and the effective signal output is more easily obtained; the signal pre-emphasis parameter refers to the variation condition of the amplitude and the signal power of high-frequency components in a signal spectrum when the frequency of a signal is increased, and the larger the signal pre-emphasis parameter is, the better the amplitude-frequency characteristic of the signal is, and the higher the high-frequency resolution of the signal is.

For example, when the transmission parameter configuration information is configuration information of a signal swing and a signal pre-emphasis parameter, please refer to table 1, where a parameter of the signal swing corresponding to a first time interval is configured to be 300mV (chinese: millivolt), a parameter of the signal pre-emphasis parameter corresponding to the first time interval is configured to be 6dB/oct (chinese: decibel/octave), a parameter of the signal swing corresponding to a second time interval is configured to be 300mV, and a parameter of the signal pre-emphasis parameter corresponding to the second time interval is configured to be 12 dB/oct.

TABLE 1

Step 404a2, the timing controller sends the test signal through the second signal line according to the parameter configuration of the originating parameter corresponding to the time interval in each time interval of the time reference signal according to the corresponding relation.

Before sending the test signal, the timing controller may search for configuration information of parameters such as a signal swing amplitude and a signal pre-emphasis parameter corresponding to each time interval in the correspondence, and send the test signal through the second signal line according to the searched configuration information of the parameters.

For example, assuming that the preset correspondence between the multiple time intervals and the different transmission parameter configuration information is the correspondence shown in table 1, according to the correspondence, the timing controller may transmit the sub-test signal corresponding to the first time interval through the second signal line in the first time interval according to the parameter configuration of the signal swing as 300mV and the parameter configuration of the pre-emphasis parameter as 6dB/oct, in the second time interval according to the parameter configuration of the signal swing as 300mV and the parameter configuration of the pre-emphasis parameter as 12dB/oct, and transmit the second sub-test signal corresponding to the second time interval through the second signal line.

The parameters are configured for the parameters of the transmitting end at the transmitting end, and the corresponding test signal is transmitted through the second signal line, so that the signal can be adjusted from the transmitting end, the attenuation degree of the signal received by the receiving end is reduced, the distortion degree of the signal is reduced, and the transmission accuracy of the signal is improved.

Alternatively, when the receiving end performs parameter configuration for the receiving end parameters, as shown in fig. 5-2, the process of the source driver chip receiving the test signal sent by the timing controller through the second signal line may include:

in step 404b1, the source driver chip obtains the corresponding relationship between the preset time intervals and different transmission parameter configuration information.

The corresponding relationship is recorded with transmission parameter configuration information of receiving end parameters corresponding to each time interval, and the receiving end parameters may include parameters such as signal equalization parameters and impedance parameters. The signal equalization parameters are used for indicating the gear positions of the signal gain, different signal equalization parameters can indicate the signal gain of different gear positions, and the signal received by the source driving chip can be enhanced according to the signal equalization parameters, so that when the received signal is attenuated and cannot be correctly received, the signal can be enhanced to the normal receiving range of the source driving chip after the signal enhancement is carried out according to the gear positions indicated by the signal equalization parameters; the impedance parameter is mainly expressed as the matching condition of the second signal line and the receiving port, and the higher the matching degree of the two is, the smaller the distortion degree of the signal received by the receiving end is.

TABLE 2

	Signal equalization parameters (Unit: dB)	Impedance parameter (Unit: omega)
			A first time interval	1	100
Second time interval	1	200
			Third time interval	2	100
A fourth time interval	2	200
			A fifth time interval	3	100
Sixth time interval	3	200

For example, when the transmission parameter configuration information is configuration information of parameters such as a signal equalization parameter and an impedance parameter, please refer to table 2 for correspondence between a plurality of preset time intervals and different transmission parameter configuration information, where the parameter of the signal equalization parameter corresponding to the first time interval is configured to be 1dB (chinese: decibel), the parameter of the impedance parameter corresponding to the first time interval is configured to be 100 Ω (chinese: ohm), the parameter of the signal equalization parameter corresponding to the second time interval is configured to be 2, and the parameter of the impedance parameter corresponding to the second time interval is configured to be 200 Ω.

Step 404b2, the source driver chip receives the test signal through the second signal line in each time interval of the time reference signal according to the corresponding relationship and according to the parameter configuration of the receiving end parameter corresponding to the time interval.

For the implementation of step 404b2, please refer to the implementation of step 404a2, which is not described herein again.

The parameters are configured for the receiving end parameters at the receiving end, and the corresponding test signals are received through the second signal line, so that the signals can be adjusted again from the receiving end, the attenuation degree of the signals received by the receiving end is further reduced, the degree of signal distortion is reduced, and the transmission accuracy of the signals is further improved.

It should be noted that the parameter configuration process performed by the transmitting end and the receiving end is performed simultaneously.

Step 405, the source driver chip determines, in a plurality of time intervals, a target time interval corresponding to the sub-test signal with the highest transmission accuracy based on each received sub-test signal.

Optionally, as shown in fig. 6, the implementation process of step 405 may include:

step 4051, comparing each sub-test signal with the pre-stored initial test signal to determine the transmission accuracy of each sub-test signal.

Step 4052, according to the transmission accuracy of each sub-test signal, determining a target time interval corresponding to the sub-test signal with the highest transmission accuracy among a plurality of time intervals.

For example, assuming that the pre-stored initial test signal is 01234012340123401234, the source driver chip receives the test signal including three sub-test signals, the three sub-test signals respectively correspond to the first time interval, the second time interval and the third time interval, and the three sub-test signals respectively are: 01233012440122201234, 01234111111123401234 and 01233012320123401234, comparing the three sub-test signals with the initial test signal stored in advance respectively, the transmission accuracy of the three sub-test signals can be respectively 80%, 75% and 90%, and the third time interval can be determined as the target time interval if the accuracy of the third sub-test signal is the highest.

The transmission accuracy of a certain sub-test signal is the highest, and it can be considered that when parameter configuration is performed according to the parameter configuration signal corresponding to the time interval corresponding to the sub-test signal, the attenuation degree and distortion degree of the signal received by the receiving end are the minimum, and the accuracy of the transmitted signal can be ensured to the maximum extent.

Step 406, the source driver chip queries a corresponding relationship between a preset time interval and the identifier of the transmission parameter configuration information to obtain the identifier of the target transmission parameter configuration information corresponding to the target time interval.

A group of transmission parameters corresponds to a time interval, and a group of transmission parameters includes a plurality of parameters, and the identifier of the transmission parameter configuration information may be an identifier of a group corresponding to the same group of transmission parameters, or may be a feature code of parameter configuration information corresponding to the plurality of parameters. And when the identifier of the target transmission parameter configuration information is determined, the source driving chip can record the identifier of the target transmission parameter configuration information in a preset register for subsequent use.

Step 407, the source driver chip sends the identifier of the target transmission parameter configuration information corresponding to the target time interval to the timing controller through the first signal line.

Correspondingly, the time schedule controller can receive the identification of the target transmission parameter configuration information sent by the source electrode driving chip through the first signal wire, and the target transmission parameter configuration information is the transmission parameter configuration information corresponding to the target time interval. And the corresponding relation between the preset time interval and the identification of the transmission parameter configuration information is also stored in the time sequence controller, and after the time sequence controller receives the identification of the target transmission parameter configuration information sent by the source electrode driving chip, the corresponding relation can be inquired according to the identification, and the target transmission parameter configuration information corresponding to the identification is determined.

For example, it is assumed that the identifier of the transmission parameter configuration information is a group identifier of a group corresponding to the same group of transmission parameters, and the same group of transmission parameters includes: table 3 may be referred to for a corresponding relationship between a preset time interval and an identifier of transmission parameter configuration information, where: the first time interval corresponds to a group identifier 1, and the corresponding transmission parameter configuration information in the group identifier 1 is: the parameter of the signal swing is configured to be 300mV, the parameter of the signal pre-emphasis parameter is configured to be 6dB/oct, the parameter of the signal equalization parameter is configured to be 1, and the parameter of the impedance parameter is configured to be 100 omega; the second time interval corresponds to a group identifier 2, and the corresponding transmission parameter configuration information in the group identifier 2 is: the parameter of the signal swing is configured to be 300mV, the parameter of the signal pre-emphasis parameter is configured to be 12dB/oct, the parameter of the signal equalization parameter is configured to be 1, and the parameter of the impedance parameter is configured to be 200 omega; the third time interval corresponds to a group identifier 3, and the corresponding transmission parameter configuration information in the group identifier 3 is: the parameter of the signal swing is configured to be 250mV, the parameter of the signal pre-emphasis parameter is configured to be 6dB/oct, the parameter of the signal equalization parameter is configured to be 2, the parameter of the impedance parameter is configured to be 100 Ω, when the target time interval is the third time interval, it can be determined that the identifier of the target transmission parameter configuration information is 3, then the source driving chip can send the group identifier 3 to the timing controller through the first signal line, after the timing controller receives the identifier, through querying the corresponding relationship, it can be determined that the target transmission parameter configuration information corresponding to the group identifier 3 is: the parameters of signal swing are configured to be 250mV, the parameters of signal pre-emphasis parameters are configured to be 6dB/oct, the parameters of signal equalization parameters are configured to be 2, and the parameters of impedance parameters are configured to be 100 omega.

TABLE 3

And step 408, the timing controller sends a signal to the source driving chip through the second signal line based on the target transmission parameter configuration information.

After receiving the identifier of the target transmission parameter configuration information, the timing controller can determine the corresponding target transmission parameter configuration information, and based on the target transmission parameter configuration information, sends a signal to the source driving chip through the second signal line so as to realize the transmission of a high-speed signal between the timing controller and the source driving chip.

In practical applications, a plurality of source driver chips are disposed on the display panel, and the plurality of source driver chips may be connected to the same timing controller, and the timing controller and each source driver chip may determine the target transmission parameter configuration information corresponding to each source driver chip according to the method for determining the transmission parameter configuration information provided by the embodiment of the present invention. After the target transmission parameter configuration information corresponding to each source driving chip is determined, high-speed signal transmission can be performed between the time schedule controller and each source driving chip through the second signal line according to the target transmission parameter configuration information corresponding to each source driving chip, so that signal attenuation is reduced, and signal transmission accuracy is improved.

Alternatively, the timing controller may send a high-speed clock signal for clock calibration to the source driver chip through the second signal line based on the target transmission parameter configuration information, and accordingly, the source driver chip may receive the high-speed clock signal according to the target transmission parameter configuration information and calibrate its internal clock according to the high-speed clock signal, so as to achieve fast locking of the internal clock. After the fast locking of the internal clock is completed, the timing controller may set the level of the first signal line to a high level and transmit other high-speed signals through the second signal line, so that the display panel performs a normal display state.

It should be noted that the implementation process of the above steps 401 to 408 may correspond to the timing chart shown in fig. 7, wherein the steps 401 to 406 correspond to a parameter adaptation phase, the step 407 corresponds to a data return phase, the step 408 corresponds to a fast clock locking phase and a display phase, and the level of the first signal line in the display phase is a high level, and accordingly, in the parameter adaptation phase, the data return phase, the fast clock locking phase and the display phase, the signal transmission condition on the second signal line is: transmitting a clock parameter set signal, transmitting some other signal or not, transmitting some signal related to a clock mode, transmitting a display related signal.

In summary, according to the method for determining transmission parameter configuration information provided in the embodiments of the present invention, the sending end and the receiving end transmit the time reference signal on the first signal line and transmit the test signal on the second signal line at the same time, so that the receiving end can determine the target time interval corresponding to the sub-test signal with the highest transmission accuracy according to the plurality of sub-test signals corresponding to the plurality of time intervals one by one, and send the identifier of the target transmission parameter configuration information corresponding to the target time interval to the sending end, so that the receiving end can determine the target transmission parameter configuration information without manual debugging, thereby improving the determination efficiency and flexibility of the transmission parameter configuration information. Moreover, when the target transmission parameter configuration information is the transmission parameter configuration information corresponding to the sub-test signal with the highest transmission accuracy when a plurality of sub-test signals are transmitted, the accuracy of the transmitted signal can be ensured to the greatest extent when the signal is transmitted based on the target transmission parameter configuration information, and the effect is particularly obvious when the signal needs to be transmitted in a large size and a short distance.
