The following explains a driving control method of a display panel according to the present invention, and a display panel capable of executing the driving control method.
The following explains a driving control method of a display panel according to the present invention, and a display panel capable of executing the driving control method.
Referring to fig. 1, a display panel 10 according to an embodiment of the present invention includes a plurality of scan lines 13-1 to 13-M, a scan driver 14 connected to the scan lines 13-1 to 13-M, a plurality of data lines 15-1 to 15-M crossing the scan lines 13-1 to 13-M, a data driver 16 connected to the data lines 15-1 to 15-M, and a pixel unit 17 formed at a crossing position of the scan lines 13-1 to 13-M and the data lines 15-1 to 15-M. The scan driver 14 sequentially generates scan signals on the scan lines 13-1 to 13-M, and the data driver 16 generates corresponding data signals on the data lines 15-1 to 15-M.
The pixel unit 17 includes a switch tube 171 and a pixel electrode 172, wherein the switch tube 171 includes a control terminal, a first connection terminal and a second connection terminal (not labeled) respectively connected to at least one of the scan lines 13-1 to 13-M, at least one of the data lines 15-1 to 15-M and the pixel electrode 172, the switch tube 171 is turned on by a scan signal applied by the scan driver 14 to at least one of the connected data lines 13-1 to 13-M, and the pixel electrode 172 is charged by a data signal applied by the data driver 16 to at least one of the connected data lines 15-1 to 15-M.
To overcome the problem of mismatch between the scan signals and the data signals corresponding to the scan lines 13-1 to 13-M due to signal delay. The invention provides a driving control method of the following display panel.
Referring to fig. 2, a driving control method of a display panel according to an embodiment of the present invention includes the steps of:
s210: the timing parameters of the scanning signals corresponding to two preset reference scanning lines (for example, 13-1 and 13-M) in the plurality of scanning lines 13-1 to 13-M are acquired.
Specifically, the timing parameters of the scanning signals corresponding to the two reference scanning lines 13-1 and 13-M are experimentally measured. For example, the timing parameters of the scan signals corresponding to the two reference scan lines 13-1 and 13-M are set in accordance with the delay of the clock signal and/or the data signal during transmission, so that the effective charging time of the connected pixel cells 17 of the reference scan lines 13-1 and 13-M is optimized. Specifically, the timing parameters of the scanning signals corresponding to 13-1 and 13-M of the two reference scanning lines are stored in the memory 19. In other embodiments, the timing parameters corresponding to the reference scan lines 13-1 and 13-M may also be obtained by calculation or set empirically. The positions of the reference scan lines 13-1 and 13-M can be selected according to the requirement, for example, the two reference scan lines 13-1 and 13-M can correspond to the first and last scan lines in the display panel 10, or any two scan lines in the display panel 10, which is determined according to the size of the display panel 10 or other requirements. Meanwhile, the number of the reference scanning lines may be arbitrarily set as required, for example, three, four, or more.
S120: the timing parameters of the scanning signals corresponding to the other scanning lines 13-N between the two reference scanning lines 13-1 and 13-M are calculated in an interpolation manner based on the timing parameters of the scanning signals corresponding to the two reference scanning lines 13-1 and 13-M.
Specifically, step S120 is performed by a controller 18, and the controller 18 is connected to the memory 19. In this embodiment, the timing parameter of the scanning signal corresponding to the first reference scanning line 13-1 of the two reference scanning lines 13-1 and 13-M may be smaller than the timing parameter of the scanning signal corresponding to the second reference scanning line 13-M according to actual needs, so that the timing parameter of the scanning signal corresponding to the other scanning line 13-N may gradually increase in the direction from the first reference scanning line 13-1 to the second reference scanning line 13-M. Specifically, the direction from the first reference scan line to the first reference scan line is the direction in which the data line transmits the signal, and it can be understood that, in other embodiments, if the two reference scan lines 13-M to 13-1 are the direction in which the data signal is transmitted, the timing parameter of the scan signal corresponding to the reference scan line 13-M is smaller than the timing parameter of the scan signal corresponding to the reference scan line 13-1, so that the timing parameters of the scan signals corresponding to the other scan lines 13-N gradually increase in the direction from the reference scan line 13-M to the reference scan line 13-1.
The specific calculation formula of the interpolation mode may be set as follows:
TN＝T1+(T2-T1)×(LN-L1)/(L2-L1)；
wherein, T1Is the timing parameter, L, of the scanning signal corresponding to the first reference scanning line 13-1 of the two reference scanning lines 13-1 and 13-M1Is the number of rows, T, corresponding to the first reference scan line 13-12Is the timing parameter, L, of the scanning signal corresponding to the second reference scanning line 13-M of the two reference scanning lines 13-1 and 13-M2Is the number of rows, T, corresponding to the second reference scanning line 13-MNIs the timing parameter, L, of the scanning signal corresponding to the other scanning lines 13-NNThe number of rows corresponding to the other scan lines 13-N.
In this embodiment, the timing parameter can be any parameter that is set for each of the scan lines 13-1 to 13-M and the scan driver 14 can generate the corresponding scan signal according to the timing parameter corresponding to each of the scan lines 13-1 to 13-M. For example, in the present embodiment, the scan driver 14 includes a plurality of sub-drivers 14-1 to 14-M, wherein each sub-driver 14-1 to 14-M is connected to the scan lines 13-1 to 13-M, and generates the scan signal with a first delay amount in response to the received trigger signal, and terminates the scan signal with a second delay amount, wherein the timing parameter may be the first delay amount, the second delay amount, or a combination of the first delay amount and the second delay amount. More specifically, in the present embodiment, the plurality of sub-drivers 14-1 to 14-M are sequentially arranged in cascade, and the sub-driver 14-1 at the uppermost stage receives the trigger signal from the outside, and the remaining sub-drivers 14-2 to 14-M receive the trigger signal from the sub-drivers 14-1 to 14-M-1 at the upper stage, and each sub-driver 14-1 to 14-M receives the clock signal from the clock signal generator 12 and counts the received clock pulses in response to the trigger signal, and further generates the scan signal when the count value reaches a first threshold value and terminates the scan signal when the count value reaches a second threshold value, where the timing parameter may be the first threshold value, the second threshold value, or a combination of the first threshold value and the second threshold value.
S130: the timing parameters of the scan signals corresponding to the other scan lines 13-N are used to generate the scan signals corresponding to the other scan lines 13-N.
After calculating the timing parameters corresponding to the other scanning lines 13-N according to the step S120, the scan driver 14 generates the scanning signals corresponding to the other scanning lines 13-N by using the timing parameters of the scanning signals corresponding to the other scanning lines 13-N. Specifically, the first delay amount, the second delay amount, or the combination of the first delay amount and the second delay amount corresponding to each of the other scanning lines 13-N is calculated according to the above formula, and the corresponding scanning signal is generated and terminated according to the calculated delay amount.
Referring to fig. 3, in the present embodiment, waveforms a1 and a2 are pulse waveforms of a scan signal and a data signal corresponding to a scan line with a smaller number of rows in the display panel shown in fig. 1, and waveforms B1 and B2 are pulse waveforms of a scan signal and a data signal corresponding to a scan line with a larger number of rows. The data signal is gradually weakened and the delay and the deformation are gradually increased along with the transmission of the data signal along the data line, and at this time, if the scanning signals corresponding to the scanning lines with different numbers of lines are still formed with the same timing parameter, the charging effect of the pixel units connected with the scanning lines with different numbers of lines is uneven. Therefore, with the driving method described above, by setting the timing parameters of the scan signals corresponding to the two reference scan lines, the effective charging time of the pixel electrode in the transmission direction of the data signal can be made to gradually increase, as shown particularly at t1 and t2 in fig. 3, as is apparent from fig. 3, t2 is greater than t 1. In this embodiment, the effective charging time refers to an overlapping portion of the on time of the switching tube of the scan signal control pixel unit and the duration of the data signal. The variation curve of the effective charging time of the pixel units of the whole display panel along with the number of the scanning lines is shown in fig. 4, and specifically, the effective charging time of the pixel units connected with the corresponding scanning lines is uniformly increased along with the increase of the number of the scanning lines.
The following description will discuss the display panel 10 having a resolution of 3840(H) x 2160 (V).
The scan lines 13-1 to 13-M of the display panel 10 have a total of 2160 lines, and the clock signal has a frequency of 74.26Mhz, so that the time Tclk of one period of the clock signal is 0.0134 μ s.
Setting a first threshold value corresponding to the first row of scanning lines as Tr according to actual needs1100, the second threshold is set to Tf 1300, that is, the sub-driver connected to the first row of scan lines clocks the clock signal after receiving the trigger signal, generates the scan signal after the count value reaches 100, and terminates the scan signal after the count value reaches 300. The effective charging time Tx1 of the display unit 17 corresponding to the first row scanning line is made 1 μ s by the above setting.
Further, a first threshold corresponding to the last row of scanning lines is set to Tr2160150, the second threshold is set to Tf2160The sub-driver connected to the last row of scan lines clocks the clock signal after receiving the trigger signal, generates the scan signal after the count value reaches 150, and terminates the scan signal after the count value reaches 350. The effective charging time Tx of the display unit 17 corresponding to the last row of scanning lines is enabled through the setting2160＝1.67μs。
Through the formula, the first threshold and the second threshold corresponding to any one row of scanning lines between the first row of scanning lines and the last row of scanning lines can be calculated.
For example, for the 500 th scan line:
Tr500100+ (150-;
for the 1800 th scan line:
Tr1800100+ (150-;
Further, the effective charging time for the other rows can be calculated by the following formula:
TxN＝Tx1+(TfN-Tf1)×Tclk
for example: the effective charging time of the scan line of the 500 th row is as follows:
Tx500＝Tx1+(Tf500-Tf1)×Tclk＝1.147μs。
the effective charging time for the scan line of the 1800 th row connected is:
Tx1800＝Tx1+(Tf1800-Tf1)×Tclk＝1.549us。
therefore, the timing parameters of other scanning lines can be calculated according to the timing parameters of the first scanning line and the last scanning line in the above mode, so that the timing parameters of all the scanning lines meet the preset change rule, and the mismatch problem of the scanning lines and the data lines caused by signal transmission can be adjusted.
It is understood that the two reference scan lines 13-1 and 13-M may not be the first and last lines of the display panel 10, and when the size of the display panel 10 is relatively small, the first reference scan line 13-1 may be a line in the middle of the display panel 10. At this time, the timing parameter of the scan line (not shown) between the first row and the first reference scan line 13-1 may be consistent with the timing parameter of the first reference scan line 13-1, or slightly smaller than the timing parameter of the first reference scan line 13-1. When the second reference scan line 13-M is not the last line of the display panel 10, the timing parameter corresponding to the scan line from the second reference scan line 13-M to the last line may be set to be equal to or slightly greater than the timing parameter of the second reference scan line 13-M, as long as the display screen of the display panel 10 is ensured to be uniform and no color cast occurs.
In the above scheme, at least two scan lines in the display panel 10 are selected as the reference scan lines 13-1 and 13-M, and the optimal charging time of the two reference scan lines 13-1 and 13-M is experimentally measured, so as to determine the timing parameters of the two reference scan lines 13-1 and 13-M. Then, the controller calculates the timing parameters of the two reference scanning lines 13-1 and 13-M in an interpolation manner, and gradually increases the effective charging time of the pixel electrode 174 in the transmission direction of the data signal for the timing parameters of the other scanning lines 13-N between the two reference scanning lines 13-1 and 13-M, thereby ensuring that the charging time of the pixel units connected with each scanning line of the display panel 10 is uniformly changed, the image display is uniform, and the color cast phenomenon does not occur.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
