Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Example 1
In order to solve the above-mentioned problems, please refer to fig. 1, fig. 1 is a flow chart of a pixel driving method according to an embodiment of the present application, as shown in fig. 1, it should be understood that the pixel driving method according to the embodiment is applied to a display panel, as shown in fig. 2, and the pixel driving method includes, but is not limited to:
s101, dividing the array into a plurality of control areas 4, wherein each control area 4 comprises at least one column of data lines 1;
s102, acquiring the charging rate of the pixels 3 in each control area 4, and adjusting the data output signal of each control area 4 according to the acquired charging rate, wherein the data output signal of the control area 4 is used for controlling the time for starting outputting data to the data line 1 in the control area 4.
And S103, charging the pixels 3 in each control area 4 according to the adjusted data output signals so as to drive the pixels 3 in each control area 4.
It should be understood that there is no parasitic capacitance on the Scan line 2 of the display panel, and the number of parasitic capacitances related to the number of pixels increases with the increase of the size of the display panel, the number of pixels 3 carried on one Scan (Scan) line increases, the parasitic capacitance increases inevitably when the pixels increase, and the Scan line increases, so that the larger RC is needed, especially the larger the difference between the leftmost RC and the rightmost RC is; when the right end of the Scan line 2 is connected to a Gate drive integrated circuit (Gate IC) of the Scan line 2, at this time, when the Scan line 2 Gate drive integrated circuit outputs a voltage, the larger the difference between the waveforms of the leftmost end Scan and the rightmost end is, the more serious the resistance-capacitance delay (RC delay) is, especially, the inconsistency of C, which results in that in the same pixel row, the charge rate of the pixels 3 close to the Gate drive integrated circuit is high, the charge rate of the pixels 3 far away from the Gate IC is low, and when each pixel 3 in the same pixel row receives a signal transmitted by the corresponding data line 1 at the same time, the charge saturation of the pixels 3 close to the Gate IC is higher than the charge saturation of the pixels 3 far away from the Gate IC, and when the pixels 3 are charged by the data lines 1 respectively connected to the near end and the far end of the same pixel row, the charge effects are different due to the difference of Gate waveforms, and further the difference of the display effects of the pixels 3 at the two ends of the pixel row is large. Therefore, the present embodiment proposes the driving method described above to solve the problem of large difference in display effect between pixels at both ends of the pixel row in the related art.
It should be understood that the pixel 3 driving method provided in this embodiment is applied to a display panel, specifically, to a central control board (TCON) in the display panel, and meanwhile, the pixels 3 in the display panel are arranged in an array, the display panel includes a plurality of pixel rows and a plurality of pixel 3 columns, where the plurality of pixel rows are in one-to-one correspondence with the plurality of scan lines 2, the plurality of pixel 3 columns are in one-to-one correspondence with the plurality of data lines 1, the coupling direction of the pixels 3 in the pixel 3 columns and the data lines 1 is not limited in this embodiment, one end of the data lines 1 is connected to a Source driving integrated circuit (Source IC), and one end of the scan lines 2 is connected to a gate driving integrated circuit; wherein, the scan control signal (OE) is used to control the time when the gate driving integrated circuit starts outputting the scan signal to the scan line 2, as shown in fig. 3, when the scan control signal (OE) outputs a falling edge, the gate driving integrated circuit starts outputting the scan signal to the scan line 2 to turn on the display control switch (TFT switch) of each pixel 3 in the pixel row, and since the RC value of one end of the scan line 2 far from the gate driving integrated circuit is large, the Ideal output (Ideal output) of the scan line 2 is different from the correction output (Correction output); the data output signal (TP) is used to control the time when the Source IC starts outputting data to the data line 1, and as shown in fig. 4, when the data output signal outputs a falling edge, the Source driving integrated circuit starts outputting data to the data line 1 to charge the pixel 3 so as to drive the pixel 3, so that the timing of charging the pixel 3 can be controlled by the controlled data output signal.
In some examples of the present embodiment, the array of the display panel is divided into a plurality of control areas 4 in a unit of one column of the data lines 1 as a minimum unit, as shown in fig. 2, because the data lines 1 correspond to the data columns, each of the control areas 4 is capable of controlling at least one column of the data rows. It will be appreciated that the charge rate of the pixels 3 within the same control area 4 is close.
In some examples of this embodiment, the number of pixels 3 in a plurality of the control areas 4 is the same, it should be understood that the number of pixels 3 in each control area 4 is equal, for example, as shown in fig. 5, the display panel is divided into three control areas 4, the number of data columns in each control area 4 is equal, the number of pixels 3 controlled by each data column is equal, and thus, the number of pixels 3 in the three control areas 4 is equal; in some examples, the columns of data controlled within at least two control regions 4 of the display panel are not equal, and the number of pixels 3 controlled by each column of pixels 3 is also not equal. It should be understood that the division of the control area 4 does not take the area of the control area 4 or the pixels 3 as a criterion, but takes the display effect of the display panel as a criterion, and the related personnel can flexibly set the data lines 1 controlled by the respective control areas 4.
In some examples of this embodiment, obtaining the charge rate of the pixels 3 in each of the control areas 4 includes: acquiring impedance values between the pixels 3 and the scanning line 2 gate driving integrated circuits in each control area 4; the charge rate of the pixels 3 in each of the control areas 4 is determined from the impedance values. It should be understood that, in the same pixel row, the greater the RC value is, the higher the impedance value between the pixel 3 connected to the scan line 2 gate driving integrated circuit and the scan line 2 gate driving integrated circuit of the scan line 2 is, and therefore, the impedance value between the pixel 3 and the scan line 2 gate driving integrated circuit, which are close to the scan line 2 gate driving integrated circuit, is lower than the impedance value between the pixel 3 and the scan line 2 gate driving integrated circuit, which are far from the scan line 2 gate driving integrated circuit. The corresponding relation between the impedance value and the charging rate is obtained by actual measurement of related personnel; it should be appreciated that the charge rates of the corresponding pixels 3 of the same data line 1 are close, while the charge rates of the individual pixels 3 within the same control area 4 are close.
In some examples of this embodiment, adjusting the data output signal of each of the control areas 4 according to the obtained charge rate includes: sequencing the obtained charging rate of each control area 4; and carrying out falling edge delay operation on the data output signal with high charging rate corresponding to the control area 4 so as to delay the time for starting to output data to the data line 1 in the control area 4. For example, there are two control areas 4 in the display panel, the data line 1 in the first control area 4 is controlled by the Source IC1, the data line 1 in the second control area 4 is controlled by the Source IC2, wherein the pixel 3 in the first control area 4 is far away from the scan line 2 gate driving integrated circuit relative to the pixel 3 in the second control area 4, the charge rate of the pixel 3 in the first control area 4 is lower than the charge rate of the pixel 3 in the second control area 4, at this time, the falling edge of the second control area 4TP1 is moved to the right relative to the falling edge of the first control area 4TP2, as shown in fig. 6, so that the time when the Source IC1 starts outputting data to the data line 1 in the second control area 4 is delayed relative to the time when the Source IC2 starts outputting data to the data line 1 in the first control area 4, so that the charge time of the pixel 3 in the first control area 4 is longer than the charge time of the pixel 3 in the second control area 4, and the charge effect of the pixel 3 in the first control area 4 is consistent with the second control area 4 is achieved, and the charge effect in the pixel 4 in the first control area 4 is achieved.
In some examples of this embodiment, adjusting the data output signal of each of the control areas 4 according to the obtained charge rate includes: sequencing the obtained charging rate of each control area 4; and carrying out falling edge advancing operation on the data output signal with low charging rate corresponding to the control area 4 so as to advance the time for starting to output data to the data line 1 in the control area 4. For example, in the display panel, there are two control areas 4, the data line 1 in the first control area 4 is controlled by the Source IC1, the data line 1 in the second control area 4 is controlled by the Source IC2, where the charge rate of the pixel 3 in the first control area 4 is lower than that of the pixel 3 in the second control area 4, at this time, the data output signal (TP 1) corresponding to the first control area 4 is subjected to the falling edge advancing operation, the falling edge of the first control area 4TP1 moves to the left with respect to the falling edge of the second control area 4TP2, so that the time when the Source IC1 in the first control area 4 starts outputting data to the data line 1 is advanced with respect to the time when the Source IC2 in the second control area 4 starts outputting data to the data line 1, so that the charge time of the pixel 3 in the first control area 4 is longer, and the effect of charging the pixel 3 in the first control area 4 is consistent with the effect of charging the pixel 3 in the second control area 4, and the display effect in the control area 4 is improved. It should be appreciated that in some examples, the source driver integrated circuits corresponding to the plurality of control regions receive the data output signals at the same time, but the source driver integrated circuits start outputting data to the data lines in the control regions at different times due to the change in the data output signals.
In some examples of this embodiment, charging the pixels 3 in each of the control areas 4 according to the adjusted data output signal includes: and respectively sending the data output signals of each control area 4 to a corresponding source drive integrated circuit, so that each source drive integrated circuit starts to carry out data output on the data line 1 according to the data output signals so as to charge the pixels 3 in each control area 4. It should be understood that in some examples, there are a plurality of Source driver ICs in the display panel, each corresponding to a different control region 4, and at this time, the adjusted data output signal is sent to the Source driver IC corresponding to the control region 4, so that the Source driver IC starts to perform data output on the corresponding data line 1 according to the data output signal, so as to charge the pixels 3 in the control region 4.
In some examples of this embodiment, charging the pixels 3 in each of the control areas 4 according to the adjusted data output signal includes: the data output signal of each control region 4 is sent to a source driving integrated circuit, so that the source driving integrated circuit starts to perform data output on the data line 1 according to the data output signal of each control region 4, and the pixels 3 in each control region 4 are charged. It should be understood that in some examples, there is only one Source driver IC in the display panel, where the Source driver IC corresponds to all the control areas 4, and at this time, all the adjusted data output signals are sent to the Source driver IC, so that the Source driver IC starts to perform data output on the corresponding data lines 1 according to the data output signals, so as to charge the pixels 3 in the control areas 4.
In the above example, when there are a plurality of source driving integrated circuits in the display panel and the control regions 4 corresponding to the source driving integrated circuits are different, TP signals of the regions may be the same; for example, when three Source driving ICs (Source IC1, source IC2, source IC 3) are included in the display panel, if the charge rates of the pixels 3 in the Source IC1 and Source IC2 control areas 4 are identical, the display effect is identical, and the Source IC3 control area 4 is another case, the Source IC1 and Source IC2 are controlled by the same TP, and the Source IC3 is controlled by a single TP, and so on.
In some examples of this embodiment, before charging the pixels 3 within each of the control regions 4 according to the adjusted data output signal, the method further comprises: according to the adjusted data output signals, correspondingly adjusting scanning control signals corresponding to each pixel row in the display panel; and scanning each pixel row in the display panel in turn according to the adjusted scanning control signals so as to turn on the display control switch of each pixel 3 in each pixel row. It should be understood that, in order to match the time when the Source IC starts outputting data to the data line 1, a certain adjustment may be made to the Scan control signal (OE) for controlling the time when the data output to the Scan line 2 starts, it should be understood that the Scan control signal after adjustment allows the upper and lower pixel rows to be offset, as shown in fig. 7, so that the Scan line 2Scan1 and the next Scan line 2Scan have overlap of simultaneous punching), t3+.t3 ', compared with OE1, for example, the graph after OE adjustment is shown in the specification with T4 not equal to T4', T1 not equal to T1', and OE2 has the effect of controlling charging time together with TP to enable the display effect after near-end and far-end charging of the scanning line 2 to be close, it should be understood that if the display panel is driven to select GOA mode (without a separate Gate IC but integrated on the glass substrate), the waveform adjustment mode is to change the relationship of CLK, in general, GOUT output waveform can be shown in FIG. 7 and not necessarily change OE signal.
The pixel driving method provided in this embodiment is applied to a display panel, where pixels 3 in the display panel are arranged in an array, and the pixel 3 driving method includes: dividing the array into a plurality of control areas 4, each control area 4 comprising at least one column of data lines 1; acquiring the charging rate of the pixels 3 in each control area 4, and adjusting the data output signal of each control area 4 according to the acquired charging rate, wherein the data output signal of the control area 4 is used for controlling the time for starting outputting data to the data line 1 in the control area 4; charging the pixels 3 in each control area 4 according to the adjusted data output signals so as to drive the pixels 3 in each control area 4; the corresponding data output signals are adjusted for the control areas 4 according to the charging rate, so that the charging effect of the control areas 4 tends to be consistent, the display uniformity of each control area 4 is improved, and the display effect of the display panel is further improved.
Example two
Based on the same conception, the present embodiment provides a display panel to which the above-described pixel driving method is applied;
as shown in fig. 8, the present example is a display panel to which the above-described pixel driving method is applied, in which the display panel is divided into a plurality of control areas 4 by Source IC internal output units, and in which only one Source IC is described as an example of two areas; the TCON inputs n TPs to the same Source IC (if the TP routing is required to be pulled separately between the two, if the TP is obtained by decomposing other signals of a special communication protocol between the two, only a plurality of TPs need to be generated inside the Source IC, in summary, only the same Source IC can be controlled to send data voltages in a partitioned mode), and the description is given in n=2 bits, because the control area 4 corresponding to TP2 is closer to the scanning control circuit than the control area 4 corresponding to TP1, the TP1 opens the corresponding control area 4 than TP2, i.e. when the TP is opened, the data voltage controlled by TP1 is output earlier than the data voltage controlled by TP2, so that the area controlled by TP1 charges earlier than the pixel 3 electrode of the area controlled by TP2, and because charging is slower, the time is prolonged, the effect TP1 can be consistent with the area controlled by TP 2; the same is true between Source IC1/2 and Source IC2/3, and similar hierarchical relationship is that the last TP of Source IC1 is compared with the first TP of Source IC 2;
as another example, the present example provides a display panel as shown in fig. 9, and fig. 9 shows a display panel to which the above-described pixel driving method is applied, in which Source ICs are divided into internal output units, and only one Source IC is taken as an example for description of two regions; the TCON inputs n TPs to the same Source IC (if the TP routing is required to be pulled separately between the two, if the TP is decomposed by other signals of a special communication protocol between the two, only a plurality of TPs need to be generated inside the Source IC, in summary, only the same Source IC can be controlled to send data voltages in a partition), and the n=2 bits introduce that TP1 opens the corresponding control area 4 earlier than TP2, that is, when the row is opened, the data voltages controlled by TP1 are output earlier than the TP2 control part, so that the area controlled by TP1 charges earlier than the pixel 3 electrode controlled by TP2, and the effect TP1 can be consistent with the area controlled by TP2 because the charging is slower and the time is prolonged; the same applies to Source IC1/2 and Source IC2/3, and the similar hierarchical relationship is that the last TP of Source IC1 is compared with the first TP of Source IC 2.
It should be understood that the partitioning may be performed by using Source IC1 and Source IC2 as one region and Source IC3 as a separate region; the subareas do not take the area of the control area 4 or the pixel 3 as a judgment standard, but take the display effect of the display panel as the standard; as the name implies, if the Source IC1 and the Source IC2 control area 4 have identical display effects, and the Source IC3 control area 4 is another case, the Source IC1 and the Source IC2 are adopted to be controlled by the same TP, the Source IC3 is controlled by a single TP, and other partitioning modes are analogized. Since the same Source IC is also controlled in a partition, as shown in fig. 10, the TP timing of the last region controlled by Source IC1 and the first region controlled by Source IC2 is the same, i.e., the last region controlled by Source IC1 and the first region controlled by Source IC2 are the same at the time of output.
