Fig. 4-1 is please referred to, Fig. 4-1 is a kind of determination method of configured transmission configuration information provided in an embodiment of the present invention Flow diagram, the embodiment of the present invention are applied in this way in application environment as shown in Figure 1, and using transmitting terminal as timing control Device processed, receiving end be source driving chip for, this method is illustrated, this method comprises:

Step 401, sequence controller send basic parameter configuration information to source driving chip.

The basic parameter configuration information is that sequence controller is believed by second signal line to source driving chip transmission test Before number, each source driving chip is required to the information of configuration, in order to the data of each source driving chip after the power-up Realize unified configuration.The basic parameter configuration information includes the configuration information of many kinds of parameters, these parameters are driven in entire panel The parameter that moving frame structure just has determined after determining, it is unrelated with actual transmission paths and signal decaying.For example, basic parameter configures Information may include that quantity (the also referred to as quantity of high-speed channel), the transmission rate of second signal line (that is to say data in each letter Transmission rate on number line) and the information such as pixel number.

Optionally, which, which can carry, passes through the first signal wire to source drive in sequence controller In the configuration-direct that chip is sent, also, the format for the instruction transmitted between sequence controller and source driving chip can phase Together, each instruction transmitted on the first signal wire can include the lead code (English: preamble) being arranged successively, starting (English: start) mark, data bit (also referred to as: transmission main body, English: transaction body) and end (English: stop) Mark, the schematic diagram of the format of the instruction please refer to Fig. 4-2.

Wherein, the receiving end that lead code is used to indicate instruction (including the instruction of the lead code) carries out clock and phase school There are preamble transmissions in the receiving end (sequence controller or source driving chip) of standard, the instruction on detecting the first signal wire When, clock and phase adjustment can be carried out according to the content of lead code, the clock and phase adjustment, which refer to, keeps clock and instruction The clock of the transmitting terminal of (including the instruction of the lead code) is consistent, and phase is identical as the transmitting terminal of instruction, the receiving end of instruction Clock and phase are adjusted during receiving lead code, after preamble transmissions, clock and phase adjustment are finished.Starting Mark is used to indicate data transmission and starts, and data bit is for carrying the data such as basic parameter configuration information, and end of identification is for referring to Show the data transfer ends.

Step 402, source driving chip carry out basic parameter configuration according to basic parameter configuration information.

Source driving chip, can be according to basic ginseng after receiving the basic parameter configuration information that sequence controller is sent Number configuration information carries out basic parameter configuration, which is the initialization of the essential information of second signal line Journey, since second signal line can be HW High Way, which is also referred to as high-speed channel when establishing connection Initialization procedure.

For example, when basic parameter configuration information includes the quantity of the second signal line of each source driving chip connection, Source driving chip saves the quantity of the second signal line of itself connection, and according to include in basic parameter configuration information second The quantity of signal wire carries out preset configuration to the second signal line of the quantity, in order to the second signal for using the configuration to complete Line receives test signal.It should be noted that one second signal line is actually when second signal line is differential signal line By two root signal line groups at signal wire.When basic parameter configuration information includes transmission rate, the transmission rate is for accusing Know source driving chip, the transmission rate when signal that will be carried out transmits enables source driving chip accurately to work Under the transmission rate of agreement.

It should be noted that under normal conditions, a source driving chip is one second signal line of connection, but Under some special screnes, a second signal line may be unable to satisfy the transmission requirement of source driving chip, so a source electrode Driving chip can also according to circumstances connect at least two second signal lines, and in practical application, basic parameter configuration information includes The quantity of the second signal line of each source driving chip connection, but when the second signal line of all source driving chips connection When quantity is identical, basic parameter configuration information can carry a second signal line number amount, indicate each source driving chip It is configured according to the quantity, the quantity such as carried is 1, i.e., each source driving chip is connect with 1 second signal line.

Basic parameter configuration information in step 402 is the ginseng just having determined after entire panel bogie structure determines Number, it is unrelated with the factors such as actual transmission paths, it further include some configured transmissions in signals transmission still, these biographies Defeated parameter will receive the influence of the factors such as actual transmission paths, therefore, before transmitting signal relevant to display, it is also necessary to really The configuration information of configured transmission is determined, to guarantee the correctness of the signal of transmission.

In the embodiment of the present invention, being transmitted on the first signal wire simultaneously by sequence controller and source driving chip has The timing reference signal of multiple time intervals, transmission test signal, enables source driving chip root on second signal line It is determined corresponding to the transmission highest sub- test signal of accuracy according to the one-to-one multiple sub- test signals of multiple time intervals Object time section, and object transmission parameter configuration corresponding to the object time section is determined as configured transmission Configuration information, in order to which sequence controller and source driving chip are based on the object transmission parameter configuration and carry out signal biography It is defeated.Wherein, the process of the configuration information of the determination configured transmission please refers to following step 403 to step 407.

Step 403, sequence controller pass through the first signal wire to source driving chip sending time reference signal.

Correspondingly, while sequence controller is to source drive signal sending time reference signal, source driving chip It receives sequence controller and passes through the timing reference signal that the first signal wire is sent.

In order to guarantee that source drive signal can effectively identify the timing reference signal, please continue to refer to Fig. 4-2, in the time The first place of reference signal can generate a hopping edge (the i.e. first place of timing reference signal and the last bit of end of identification with end of identification Numerical value is different, for example, the first place of timing reference signal is 1,0) last bit of end of identification is.Meanwhile the end of timing reference signal Position can generate a hopping edge with the first of next signal.It, can be in order to which source driving chip be by time reference by hopping edge Signal and other signal distinguishings.

The timing reference signal has multiple time intervals, and each time interval has apparent distinguishing identifier.It is multiple Time interval is used for when source driving chip receives multiple signals, provides time reference effect for source driving chip, To distinguish different time sections received signal.Optionally, in timing reference signal, the first place in latter time section can be with The last bit of previous time interval generates a hopping edge can be believed time reference in order to source driving chip by the hopping edge Multiple time intervals in number are distinguished, and then realize effective identification of data.Alternatively, can be using the clock with multiple periods Signal serves as the timing reference signal, and each time interval may include the clock signal at least one period.Since clock is believed Number there is fixed clock frequency, when serving as timing reference signal using clock signal, can simply and accurately realize time zone Between reference role.

Step 404, while sending time reference signal, sequence controller by second signal line send test letter Number.

When sequence controller passes through the first signal wire sending time reference signal, test letter is also sent by second signal line Number, correspondingly, source driving chip, while receiving time reference signal, also reception sequence controller passes through second signal line The test signal of transmission.Received test signal include with the one-to-one multiple sub- test signals of multiple time intervals, Multiple sub- test signal is respectively that same initial test signal is based on difference between sequence controller and source driving chip Configured transmission configuration information transmission it is obtained, and every height test signal it is corresponding with a time interval, according to time zone Between reference role, source driving chip can distinguish multiple sub- test signal, and then receives and carry different letters Multiple sub- test signals of breath.

Wherein, which is that respectively same group of configured transmission carries out different parameter configurations It is obtained, since the transmission process is issued signal by transmitting terminal (i.e. sequence controller) and by receiving end (i.e. source electrode drive Dynamic chip) it is received, which may include: originator parameter and receiving end parameter, therefore, the different transmission ginseng Number configuration information may include: transmitting terminal for originator parameter carry out parameter configuration, and receiving end be receiving end parameter carry out Parameter configuration.

Optionally, when transmitting terminal is that originator parameter carries out parameter configuration, as shown in fig. 5-1, sequence controller passes through the Binary signal line sends the process of test signal, may include:

Step 404a1, sequence controller obtains preset multiple time intervals and different configured transmission configuration informations Corresponding relationship.

The configured transmission configuration information of originator parameter corresponding with each time interval, the hair are recorded in the corresponding relationship Holding parameter may include the parameters such as signal swing and signal pre-emphasis parameters.Wherein, signal swing refer to the maximum value of signal with The difference of minimum value, when signal swing is bigger, the fluctuation of signal is just more obvious, and is more easy to get effective signal output；Signal When pre-emphasis parameters refer to the frequency increase of signal, the amplitude of signal spectrum high frequency components and the situation of change of signal power, When signal pre-emphasis parameters are bigger, the amplitude-frequency characteristic of signal is better, and the high frequency resolution of signal is higher.

Illustratively, it when configured transmission configuration information is the configuration information of signal swing and signal pre-emphasis parameters, presets Multiple time intervals please refer to table 1 from the corresponding relationship of different configured transmission configuration informations, wherein first time section pair The parameter configuration for the signal swing answered is 300mV (Chinese: millivolt), the ginseng of the corresponding signal pre-emphasis parameters in first time section Number is configured to 6dB/oct (Chinese: decibel/octave), and the parameter configuration of the corresponding signal swing of the second time interval is 300mV, the parameter configuration of the corresponding signal pre-emphasis parameters of the second time interval are 12dB/oct.

Table 1
