Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in 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 obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
In order to solve the above problem, please refer to fig. 1, and fig. 1 is a schematic flow chart of a pixel driving method according to an embodiment of the present disclosure, as shown in fig. 1, it should be understood that the pixel driving method according to the present embodiment is applied to a display panel, as shown in fig. 2, 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;
and 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 to output data to the data lines 1 in the control area 4.
And S103, charging the pixels 3 in each control area 4 according to the adjusted data output signal so as to drive the pixels 3 in each control area 4.
It should be understood that parasitic capacitance is not left on the Scan line 2 of the display panel, and the number of parasitic capacitances and the number of pixels are related, as the size of the display panel increases, the number of pixels 3 carried on one Scan (Scan) line also increases, the parasitic capacitance necessarily increases when the number of pixels increases, and the Scan routing also increases, the RC tends to be larger, especially the difference between the RC at the leftmost end and the RC at the rightmost end is larger; when the right end of the Scan line 2 is connected to a Gate driver integrated circuit (Gate IC) of the Scan line 2, and the Gate driver IC of the Scan line 2 outputs a voltage, the waveform of the Scan at the leftmost end differs from the waveform at the rightmost end, the more severe the resistance-capacitance delay (RC delay), especially the C disparity, causes a large amount of delay in the same pixel row, the pixel 3 near the Gate drive IC has a high charge rate, the pixel 3 far from the Gate IC has a low charge rate, when the pixels 3 in the same pixel row receive signals transmitted from the corresponding data lines 1 at the same time, the charging saturation of the pixels 3 close to the Gate IC is higher than that 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 charging effects are different due to different Gate waveforms, so that the display effects of the pixels 3 at the two ends of the pixel row are different greatly. Therefore, the present embodiment proposes the above driving method to solve the problem of large difference in display effect between pixels at two ends of a pixel row in the related art.
It should be understood that the driving method for the pixel 3 provided in this embodiment is applied to a display panel, and in particular, to a central control board (TCON) in the display panel, and meanwhile, the pixel 3 in the display panel is 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 correspond to the plurality of scan lines 2 one to one, the plurality of pixel 3 columns correspond to the plurality of data lines 1 one to one, a coupling direction between the pixel 3 and the data line 1 in the pixel 3 columns is not limited in this embodiment, one end of the data line 1 is connected to a Source driver integrated circuit (Source IC), and one end of the scan line 2 is connected to a gate driver integrated circuit (gate IC); as shown in fig. 3, when the output of the scan control signal (OE) falls, 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 because the RC value of the end of the scan line 2 away 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 to output data to the data line 1, and as shown in fig. 4, when the data output signal output falls, the Source driver IC starts to output data to the data line 1 to charge the pixel 3, so as to drive the pixel 3, and thus, the timing of charging the pixel 3 can be controlled by controlling the data output signal.
In some examples of the present embodiment, the array of the display panel is divided into a plurality of control regions 4 in a unit of a minimum of one column of the data lines 1, as shown in fig. 2, each of the control regions 4 can control at least one column of data rows because the data lines 1 correspond to the data columns. It will be appreciated that the charging rates of the pixels 3 within the same control area 4 are close.
In some examples of the present embodiment, the number of pixels 3 in a plurality of the control regions 4 is the same, and it should be understood that the number of pixels 3 in each control region 4 is equal, for example, as shown in fig. 5, the display panel is divided into three control regions 4, the number of data columns in each control region 4 is equal, the number of pixels 3 controlled by each data column is equal, and therefore, the number of pixels 3 in three control regions 4 is equal; in some examples, the columns of data controlled within the 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 region 4 is not based on the area of the control region 4 or the pixels 3 being equal, but based on the display effect of the display panel, the relevant person can flexibly set the data lines 1 controlled by the respective control regions 4.
In some examples of the present embodiment, obtaining the charge rate of the pixels 3 in each of the control regions 4 includes: acquiring an impedance value between the pixel 3 and the scanning line 2 gate drive integrated circuit in each control area 4; the charging 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, since the larger the RC value is, the higher the impedance value between the pixel 3 and the scan line 2 gate driver integrated circuit connected with the scan line 2 gate driver integrated circuit is, the farther away from the scan line 2 gate driver integrated circuit is, the higher the impedance value is, the impedance value between the pixel 3 and the scan line 2 gate driver integrated circuit close to the scan line 2 gate driver integrated circuit is lower than the impedance value between the pixel 3 and the scan line 2 gate driver integrated circuit far from the scan line 2 gate driver integrated circuit. Wherein, the corresponding relation between the impedance value and the charging rate is obtained by the actual measurement of related personnel; it will be appreciated that the charging rates of the pixels 3 corresponding to the same data line 1 are close, while the charging rates of the individual pixels 3 within the same control area 4 are close.
In some examples of the present embodiment, adjusting the data output signal of each of the control areas 4 according to the acquired charging rate includes: sequencing the acquired charging rate of each control area 4 in a high-low mode; and carrying out falling edge delay operation on the data output signal with the high charging rate corresponding to the control area 4, so that the time delay of outputting data to the data line 1 in the control area 4 is started. For example, two control regions 4 are present in the display panel, the data line 1 in the first control region 4 is controlled by the Source IC1, the data line 1 in the second control region 4 is controlled by the Source IC2, wherein the pixels 3 in the first control region 4 are far away from the scan line 2 gate drive integrated circuit relative to the pixels 3 in the second control region 4, the charging rate of the pixels 3 in the first control region 4 is lower than that of the pixels 3 in the second control region 4, at this time, the data output signal (TP2) corresponding to the second control region 4 is subjected to a falling edge delay operation, the falling edge of the second control region 4TP1 is shifted to the right relative to the falling edge of the first control region 4TP2, as shown in fig. 6, so that the time at which the Source IC1 in the second control region 4 starts to output data to the data line 1 is delayed relative to the time at which the Source IC2 in the first control region 4 starts to output data to the data line 1, therefore, the charging time of the pixels 3 in the first control area 4 is longer, the effect of charging the pixels 3 in the first control area 4 is consistent with the charging effect of the pixels 3 in the second control area 4, and the display effect in the control area 4 is improved.
In some examples of the present embodiment, adjusting the data output signal of each of the control areas 4 according to the acquired charging rate includes: sequencing the acquired charging rate of each control area 4 in a high-low mode; the charging rate is low and the data output signal of the control area 4 is subjected to falling edge advance operation, so that the time for outputting data to the data line 1 in the control area 4 is advanced. For example, two control regions 4 exist in the display panel, the data line 1 in the first control region 4 is controlled by the Source IC1, the data line 1 in the second control region 4 is controlled by the Source IC2, wherein the charging rate of the pixel 3 in the first control region 4 is lower than that of the pixel 3 in the second control region 4, at this time, the data output signal (TP1) corresponding to the first control region 4 is subjected to falling edge advancing operation, the falling edge of the first control region 4TP1 is moved to the left relative to the falling edge of the second control region 4TP2, so that the time for the Source IC1 in the first control region 4 to start outputting data to the data line 1 is advanced relative to the time for the Source IC2 in the second control region 4 to start outputting data to the data line 1, so that the charging time of the pixel 3 in the first control region 4 is longer, and the effect of charging the pixel 3 in the first control region 4 is consistent with the charging effect of the pixel 3 in the second control region 4, the display effect in the control area 4 is improved. It should be understood that in some examples, the data output signals are received at the same time by the source driver integrated circuits corresponding to the plurality of control regions, but the data output signals are changed, so that the data output times of the data lines in the control regions by the source driver integrated circuits are different.
In some examples of the present embodiment, charging the pixels 3 in each of the control regions 4 according to the adjusted data output signal includes: and respectively sending the data output signal of each control area 4 to a corresponding source drive integrated circuit, so that each source drive integrated circuit starts to output data to the data line 1 according to the data output signal, and the pixels 3 in each control area 4 are charged. It should be understood that, in some examples, a plurality of Source driver integrated circuits Source ICs are present in the display panel, each Source driver integrated circuit corresponds to a different control region 4, and at this time, the adjusted data output signal is sent to the Source driver integrated circuit corresponding to the control region 4, so that the Source driver integrated circuit starts to perform data output on the corresponding data line 1 according to the data output signal to charge the pixel 3 in the control region 4.
In some examples of the present embodiment, charging the pixels 3 in each of the control regions 4 according to the adjusted data output signal includes: and sending the data output signal of each control area 4 to a source driving integrated circuit, so that the source driving integrated circuit starts to perform data output on the data lines 1 according to the data output signal of each control area 4 to charge the pixels 3 in each control area 4. It should be understood that in some examples, there is only one Source driver IC in the display panel, and the Source driver IC corresponds to all the control regions 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 output data to the corresponding data lines 1 according to the data output signals, so as to charge the pixels 3 in the control regions 4.
In the above example, when a plurality of source driver ics exist in the display panel and the control regions 4 corresponding to the source driver ics are different, the TP signals of the regions may be the same; for example, when the display panel includes three Source driver ICs (Source IC1, Source IC2, and Source IC3), if the charging rates of the pixels 3 in the Source IC1 and Source IC2 control regions 4 are the same, the display effect is the same, and the Source IC3 control region 4 is the other case, the Source IC1 and the Source IC2 are controlled by the same TP, the Source IC3 is controlled by a single TP, and so on.
In some examples of this embodiment, before charging the pixels 3 in each of the control regions 4 according to the adjusted data output signal, the method further comprises: correspondingly adjusting the scanning control signal corresponding to each pixel row in the display panel according to the adjusted data output signal; and scanning each pixel row in the display panel in sequence according to the adjusted scanning control signal so as to open the display control switch of each pixel 3 in each pixel row. It should be understood that, in order to match the timing at which the Source IC starts outputting data to the data line 1, therefore, a certain adjustment may be made to the Scan control signal (OE) for controlling the timing at which the data output to the Scan line 2 is started, it should be understood that the adjusted Scan control signal causes the upper and lower pixel rows to be charged by mistake, as shown in fig. 7, and as far as possible, does not cause the Scan line 2Scan1 and the next Scan line 2Scan to overlap by simultaneous chucking, T3 ≠ T3 ', T4 ≠ T4 ', T1 ≠ T1 ', OE2 is adjusted as compared with OE1, as in the OE adjusted graph, and the effect is also to control the charging timing together with TP, so that the display effect after the near-end and far-end charging of the Scan line 2 is made to be close, and it should be understood that if the display panel drive selects the GOA mode (without a separate Gate IC, integrated on the glass substrate), the manner of adjusting the waveform is changed from CLK, in short, the GOUT output waveform can be as shown in fig. 7, and the OE signal is not necessarily changed.
The pixel driving method provided by the embodiment is applied to a display panel, wherein pixels 3 in the display panel are arranged in an array, and the pixel 3 driving method comprises the following steps: dividing the array into a plurality of control areas 4, wherein each control area 4 comprises 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 to output data to the data lines 1 in the control area 4; charging the pixels 3 in each of the control regions 4 according to the adjusted data output signal to drive the pixels 3 in each of the control regions 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 concept, the present embodiment provides a display panel to which the above-described pixel driving method is applied;
as shown in fig. 8, the pixel driving method is applied to a display panel, in which a Source IC internal output unit divides the display panel into a plurality of control regions 4, and only one Source IC is taken as an example for description; the TCON inputs n TPs to the same Source IC (if the TP is obtained by splitting other signals of a special communication protocol between the two, only a plurality of TPs need to be generated inside the Source IC, in short, only the same Source IC partition can be controlled to transmit data voltage), introduced with n 2 bits, because the control region 4 corresponding to TP2 is closer to the scan control circuit than the control region 4 corresponding to TP1, TP1 opens the corresponding control region 4 before TP2, that is, when the row is opened, the data voltage controlled by TP1 is output before the TP2 control part, so that the region controlled by TP1 is charged before the pixel 3 electrode controlled by TP2, because the TP is charged slowly, the time is lengthened, and the effect 1 can be achieved to be consistent with the region controlled by TP 2; the same applies to Source IC1/2 and Source IC2/3, and similar level-pass relationships exist, i.e., the last TP of Source IC1 is compared with the first TP of Source IC 2;
for another example, the present example provides a display panel as shown in fig. 9, where fig. 9 shows a display panel, and the pixel driving method is applied to the display panel, and the Source IC internal output unit is divided into two regions, and only one Source IC is taken as an example for description; inputting n TPs (if the TP is obtained by decomposing other signals of a special communication protocol between the TCON and the TCON, only a plurality of TPs need to be generated inside the Source IC if the TP is obtained by independently pulling the TP wire, in short, only the same Source IC partition can be controlled to send data voltage), introducing the data with n being 2 bits, opening the corresponding control area 4 earlier by TP1 than TP2, namely outputting the data voltage controlled by TP1 earlier than the TP2 control part when the row is opened, so that the area controlled by TP1 is charged earlier than the area pixel 3 electrode controlled by TP2, and because the charging is slow and the time is prolonged, the TP1 can be consistent with the area controlled by TP 2; the same applies to Source IC1/2 and Source IC2/3, similar to the hierarchical relationship, i.e., the last TP of Source IC1 is compared to the first TP of Source IC 2.
It should be understood that the partitioning manner may be that the Source IC1 and the Source IC2 are one area, and the Source IC3 is a single area; the area of the control area 4 or the pixels 3 are not taken as a judgment standard for the subarea, but the display effect of the display panel is taken as a standard; as the name implies, if the display effect of the Source IC1 and the display effect of the Source IC2 control area 4 are consistent, and the display effect of the Source IC3 control area 4 is another case, the Source IC1 and the Source IC2 are controlled by the same TP, the Source IC3 is controlled by a single TP, and the other partition modes are analogized in sequence. Because the inside of the same Source IC is also controlled in a partitioning mode, as shown in FIG. 10, the TP time sequence of the last area controlled by the Source IC1 is the same as that of the first area controlled by the Source IC2, that is, the TP time sequence of the last area controlled by the Source IC1 is the same as that of the first area controlled by the Source IC2 when outputting.
