The present application relates to the technical filed of liquid crystal display apparatuses, and more particularly to a liquid crystal display panel drive method and device, a liquid crystal display apparatus, and a storage medium.
Compared with traditional display apparatuses containing high-voltage components (such as Cathode Ray Tube (CRT)), liquid crystal display apparatuses have the advantages of low radiation, large visual area, small size, light weight, and good picture quality. The liquid crystal display apparatus is usually driven in a polarity reversal manner, the voltage (Vs) of the data drive signal provided by the data line being higher than the common voltage (Vcom) provided by the common electrode line is defined as positive (“+”) polarity, and the voltage of the data drive signal being lower than the common electrode voltage is defined as negative (“−”) polarity. The common electrode line is easily affected by the signal interference of the data line to generate a voltage jitter phenomenon, which leads to the crosstalk phenomenon in the screen displayed by the liquid crystal display apparatus.
In view of this, an embodiment of the present application provides a drive method and device, a liquid crystal display apparatus and a storage medium to solve the problem that the signal interference of the data line onto the common electrode line results in the crosstalk phenomenon of the picture displayed by the liquid crystal display apparatus.

In the drive method provided in the first aspect of the embodiment of the present application, the target pixel with grayscale value being greater than the preset grayscale value in a corresponding frame according to the grayscale data of any frame; then the a number difference between positive polarities and negative polarities in polarities of data drive signals of target pixels in a same row in the picture of the frame is acquired; then, in case that there is a target row with the number difference of the target row being greater than the preset number, the polarity of the data drive signal of the target pixel of the target row in the data drive signal of the frame is adjusted, such that the absolute value of the number difference corresponding to the target row is less than or equal to the preset number determined based on the value of the parasitic capacitor between the data line and the common electrode line of the liquid crystal display panel; and finally, the liquid crystal display panel is driven to display the picture of the frame based on the data drive signal of the frame after being adjusted. Thus, the crosstalk phenomenon caused by the signal interference of the common electrode line by the data line can be effectively improved, and the picture quality of the liquid crystal display panel can be improved.
It can be understood that the beneficial effects of the second to fourth aspects mentioned above can be found in the relevant descriptions in the first aspect, and which will not be further elaborated here.

The embodiment of the present application provides a drive method for driving a liquid crystal display panel. By adjusting the polarity of the data drive signal output to the target pixel with a larger grayscale value in each row, the number difference between positive polarities and negative polarities of the data drive signal of the target pixel in the same row is reduced. It can effectively improve the crosstalk phenomenon caused by the signal interference of the common electrode line and improve the picture quality of the liquid crystal display panel.
In the application, when the liquid crystal display panel displays a picture of any frame, the severity of the crosstalk phenomenon of pixels in any row of the liquid crystal display panel is positively correlated with the signal interference of the common electrode line connected to the pixels in the row, and the signal interference is related to the number difference between positive polarities and negative polarities of the data drive signal provided by the data line connected to the pixels in the row. in case that the number of the positive polarity is greater than the number of the negative polarity, the common voltage provided by the common electrode line jitters upward. in case that the number of the negative polarity is greater than the number of the positive polarity, the common voltage provided by the common electrode line jitters downward, the severity of the jitter is positively correlated with a number of the number difference, the jitter will lead to the picture displayed by the liquid crystal display panel is bright or dark (that is, crosstalk phenomenon), thus affecting the picture quality.
In the application, the liquid crystal display apparatus can include but is not limited to a color film substrate, an array substrate, and liquid crystals filled between the color film substrate and the array substrate.
A spacer is arranged between the color film substrate and the array substrate for supporting therebetween, the color film substrate is provided with a common electrode layer and a black matrix, and the array substrate is provided with a pixel electrode at a position of an opening region of the color film substrate. The positions of the array substrate covered by the black matrix are provided with a common electrode, a gate line, a data line and a switching element.
The drain electrode, source electrode and gate electrode of the switching element are electrically connected with the pixel electrode, the data line and the gate line respectively, the data line is electrically connected with a source driver, and the gate line is electrically connected with a gate driver.
Based on the structure of the above liquid crystal display apparatus, the working principle of the liquid crystal display apparatus is as follows:
When the gate driver outputs a turn-on voltage to the gate electrode of the switching element through the gate line and the source driver outputs a data drive signal to the source electrode of the switching element through the data line, the switching element is turned on. At this time, the active layer of the switching element forms a conductive channel between the source electrode and the drain electrode, and the data drive signal is transmitted to the pixel electrode through the conductive channel between the source electrode and the drain electrode, and the pixel voltage is formed at the pixel electrode.
The liquid crystal molecules located at the position of the pixel electrode is deflected by the electric field generated by the voltage difference between the common voltage accessed by the common electrode layer and the pixel voltage. The light emitted from the backlight plate is refracted through the deflected liquid crystal molecules and then emitted out from the color film substrate, and the brightness of the emitted light is proportional to the voltage difference between the pixel voltage and the common voltage.
When the gate driver outputs the turn-off voltage to the gate electrode of the switching element through the gate line and the source driver outputs the data drive voltage to the source electrode of the switching element through the data line, the switching element is turned off. At this time, the channel formed in the active layer of the switching element is cutoff, which makes the cutoff between the source electrode and the drain electrode, and the data drive voltage output by the source driver cannot be transmitted to the pixel electrode.
In a frame duration, the duration of the gate driver outputting the turn-off voltage is more than that of outputting the turn-on voltage, and after the switching element is turned off, due to the charge retention action of a parallel-plate capacitor (also known as a Storage Capacitor (CST)) formed between the wiring of the drain electrode of the switching element and the wiring of the common electrode, or formed between the wiring of the drain electrode of the switching element and the wiring of the gate electrode of the next switching element, so that the voltage difference between the pixel voltage and the common voltage can be maintained until the beginning of the next frame after the switching element is turned off, and the liquid crystal molecule can keep deflecting within one frame duration.
Based on the above principle, the liquid crystal molecules deflection at the positions of all pixel electrodes of the liquid crystal display apparatus can cause the liquid crystal display apparatus to display a picture of one frame.
As shown in
In step S101, determining a target pixel in a picture of a (k+1)-th frame according to a grayscale data of the (k+1)-th frame; and then entering the step S102.
In the application, when the liquid crystal display apparatus receives an image data of the (k+1)-th frame, the grayscale data of the (k+1)-th frame is extracted based on the image data of the (k+1)-th frame, the image data of the (k+1)-th frame is used to drive the liquid crystal display panel to display the picture of the (k+1)-th frame, and the grayscale data of the (k+1)-th frame contains the grayscale value of each pixel in the picture of the (k+1)-th frame. The processor of the liquid crystal display apparatus generates the data drive signal corresponding to the (k+1)-th frame according to the grayscale data of the (k+1)-th frame.
In the application, k is an arbitrary integer greater than or equal to 0, that is, the picture of the (k+1)-th frame can be a picture of any frame, that is, the drive method provided in the embodiment of the present application can be used to drive the liquid crystal display panel to display the picture of any frame. Correspondingly, the image data of the (k+1)-th frame, the grayscale data of the (k+1)-th frame, and the (k+1)-th frame data drive signal, are the data or signal needed to drive the liquid crystal display panel to display the picture of the (k+1)-th frame. When the value of k changes continuously (for example, k=0,1,2, . . . m, and m is any positive integer), it can drive the liquid crystal display panel to continuously display pictures of m frames or videos containing the pictures of m frames.
In the application, the data drive signal provided by the data line connected to the solid pixel corresponding to the virtual pixel with low grayscale value in the (k+1)-th frame (that is, the pixels in the liquid crystal display panel) has very little impact on the voltage of the common electrode, which is almost negligible. Therefore, it is only necessary to consider the polarity of the data drive signal accessed by the solid pixel corresponding to the virtual pixel (defined as the target pixel) whose grayscale value is greater than the preset grayscale value in the picture of the (k+1)-th frame. The preset grayscale threshold can be set to a higher grayscale value as required, for example, any value from 120 to 127, which can be 120 or 127.
In one embodiment, the step S101 includes:
In the application, in case that the picture of the (k+1)-th frame is not the picture of the first frame that the liquid crystal display panel needs to display, but the picture of the second frame or any frame after the second frame, since the polarity of the data drive signal of the target pixel in the target row of the data drive signal of the k-th frame has been adjusted when the picture of the k-th frame before he picture of the (k+1)-th frame is displayed, such that the absolute value of the number difference corresponding to the target row in the picture of the k-th frame is less than or equal to the preset number. Therefore, in case that the grayscale of the picture of the (k+1)-th frame does not change relative to the picture of the k-th frame, that is, the grayscale data of the (k+1)-th frame is the same as that of the k-th frame, it is not necessary to adjust the polarity of the data drive signal of the target pixel in the target row in the (k+1)-th frame data drive signal. It can directly adopt the same polarity as the data drive signal of the k-th frame, which can effectively simplify the drive process and improve the drive efficiency. in case that the grayscale of the picture of the (k+1)-th frame changes relative to the picture of the k-th frame, that is, the grayscale data of the (k+1)-th frame is the same as that of the k-th frame, that is, the grayscale data of the (k+1)-th frame is different from that of the k-th frame, then the polarity of the data drive signal of the target pixel of the target row in the (k+1)-th frame data drive signal is needed to be adjusted again. In other words, the steps S101 to S104 is needed to be performed.
In one embodiment, after the step S101, the method further includes:
In the application, in case that the number of target pixels in at least one row is greater than the preset number, there may be a target row where the number difference is greater than the preset number, and the step S102 can continue to be performed. In the case that the number of target pixels in each row is less than or equal to the preset number, there can be no a target row where the number difference is greater than the preset number, at this time, there is no need to continue to perform the step S102, and there is no need to adjust the polarity of the data drive signal of the target pixel, and the liquid crystal display panel can be directly driven to display the picture of the (k+1)-th frame according to the image data of the (k+1)-th frame; and the drive process is simple and the drive efficiency is improved.
In step S102, acquiring a number difference between positive polarities and negative polarities in polarities of data drive signals of target pixels in a same row in the picture of the (k+1)-th frame; then entering a step S103.
In the application, since when the liquid crystal display panel displays the picture of the (k+1)-th frame, the severity of the crosstalk phenomenon of pixels in any row of the liquid crystal display panel is positively correlated with the signal interference of the common electrode line connected to the pixels in this row, and the signal interference is related to the number difference between positive polarities and negative polarities of the data drive signal provided by the data line connected to the pixels in this row. Therefore, before driving the liquid crystal display panel to display the picture of the (k+1)-th frame, it is necessary to acquire the number difference between positive polarities and negative polarities of the data drive signal that the corresponding solid pixel of each row of target pixels in the picture of the (k+1)-th frame needs to be accessed. The number difference between positive polarity and the negative polarity in the polarity of the data drive signal of the target pixel in the same row is acquired by: acquiring the number of data drive signals with the positive polarity in the data drive signal of the target pixel in the same row (defined as a first number), acquiring the number of data drive signals with the negative polarity in the data drive signal of the target pixel in the same row (defined as a second number), and then calculating the difference between the first number and the second number as the number difference.
As shown in
In the step S103, adjusting, in case that there is a target row with a number difference of the target row being greater than a preset number, a polarity of a data drive signal of a target pixel of the target row in the (k+1)-th frame data drive signal, and making an absolute value of the number difference corresponding to the target row to be less than or equal to the preset number; then entering a step S104.
In the application, after the number differences between positive polarity and the negative polarity in the polarity of the data drive signal of the target pixel in each row are acquired, that is, comparing the number difference corresponding to each row with the preset number, the row where the number difference is greater than the preset number in the picture of the (k+1)-th frame is defined as the target row. The crosstalk phenomenon can effectively improve or even be eliminated by only adjusting the polarity of the data drive signal of the target pixel in the target row in the (k+1)-th frame data drive signal, and making the absolute value of the number difference corresponding to the target row is less than or equal to the preset number. In case that there are no rows in the picture of the (k+1)-th frame with a number difference greater than the preset number, it indicates that crosstalk phenomenon will not occur when the original (k+1)-th frame data drive signal is used to drive the liquid crystal display panel to display the picture of the (k+1)-th frame, and there is no need to adjust the (k+1)-th frame data drive signal.
In the application, the preset number corresponding to the target row in the picture of the (k+1)-th frame (or the (k+1)-th frame data drive signal) is positively correlated with the value of the parasitic capacitor between the data line and the common electrode line connected to the solid pixel of the target row in the liquid crystal display panel. The larger the parasitic capacitor, the larger the preset number needs to be set to a larger value. The parasitic capacitor include a capacitor of liquid crystal and a storage capacitor, and the capacitor of liquid crystal (CLC) is a flat plate capacitor formed between the wiring of the pixel electrode of the solid pixel and the wiring of the common electrode line. Since the value of the parasitic capacitor corresponding to each row of pixels in the liquid crystal display panel of different liquid crystal display apparatuses are different. Therefore, the different preset numbers can be set for different liquid crystal display apparatuses to reduce the difficulty of adjusting the polarity of the data drive signal of different liquid crystal display apparatuses.
In one embodiment, the preset number can be set to 0.
In the application, for different liquid crystal display apparatuses, the preset number can be set to 0, so that there is no need to set different preset numbers for different liquid crystal display apparatuses, which can effectively reduce the implementation difficulty of the drive method, so that it can be widely used in different liquid crystal display apparatuses.
In one embodiment, the step S103 includes:
Adjusting, in case that there is a target row with the number difference of the target row being greater than the preset number, the polarity of the data drive signal of the target pixel of the target row in the (k+1)-th frame data drive signal in a partitioned manner, and making the absolute value of the number difference corresponding to the target row to be less than or equal to the preset number.
In the application, in order to reduce the difficulty of adjusting the polarity of the data drive signal of the target pixel of the target row, the target pixel of each target row can be divided into a plurality of regions in advance, and then the polarity inversion mode of the data drive signal of the target pixel in the same region can be made the same, so as to bulk adjust the polarity of the data drive signal for all target pixels in each region. The polarity inversion mode includes, but is not limited to: a frame inversion mode, a column inversion mode, a dot inversion mode, a row inversion mode, a 1+2line inversion mode, and a line inversion mode, etc.
In one embodiment, the number of the target pixels in each region are the same; or, the number of the target pixels in at least two regions are different.
In the application, the number of target pixels divided by each target row and the number of target pixels in each region is not limited, which can be set according to actual needs. The more the number of regions, the higher the adjustment accuracy. The number of target pixels in different regions can be the same or different.
In one embodiment, in case that the picture of the (k+1)-th frame includes a plurality of sub-frames that are the same, the target pixels belonging to the same sub-frame in the target row are divided into one region.
In the application, in case that the (k+1)-th frame includes the plurality of sub-frames that are the same, a feasible region division rule for the target pixels in each target row is as follows: the target pixels belonging to the same sub-frame in each target row are divided into one region. This partition method can effectively simplify the process of region partitioning and improve the efficiency of data processing.
As shown in
In one embodiment, the step S103 includes:
In case that there is a target row with the number difference of the target row being greater than the preset number, and the number difference corresponding to the target row in the (k+1)-th frame is the same as that of in a k-th frame, then adjusting a polarity inversion mode of the data drive signal of the target pixel in the target row in the (k+1)-th frame data drive signal to be the same as that of a data drive signal of the k-th frame, and making the absolute value of the number difference corresponding to the target row in the (k+1)-th frame data drive signal to be less than or equal to the preset number; and where k is an arbitrary integer greater than 0.
In the application, in case that the picture of the (k+1)-th frame is not the picture of the first frame that the liquid crystal display panel needs to display, but the picture of the second frame or any frame after the second frame, since the polarity of the data drive signal of the target pixel in the target row of the data drive signal of the k-th frame has been adjusted by using the determined polarity inversion mode when the picture of the k-th frame before he picture of the (k+1)-th frame is displayed, such that the absolute value of the number difference corresponding to the target row in the picture of the k-th frame is less than or equal to the preset number. Therefore, in case that the number difference corresponding to the target row in the picture of the (k+1)-th frame does not change relative to that of the target row in the picture of the k-th frame, then the polarity inversion mode used to adjust the polarity of the data drive signal of the target pixel of the target row in the data drive signal of the picture of the k-th frame can be used to the polarity of the data drive signal of the target pixel of the target row in the data drive signal of the picture of the (k+1)-th frame, which can effectively simplify the driving process and improve the driving efficiency. in case that the number difference corresponding to the target row in the picture of the (k+1)-th frame changes relative to that of the target row in the picture of the k-th frame, the polarity inversion mode suitable for the picture of the (k+1)-th frame needs to be adopted according to the actual situation to adjust the polarity of the data drive signal of the target pixel in the target row in the (k+1)-th frame data drive signal.
In step S104, driving the liquid crystal display panel to display the picture of the (k+1)-th frame based on the (k+1)-th frame data drive signal after being adjusted.
In the application, after adjusting the polarity of the data drive signal of the target pixel in each target row in the (k+1)-th frame data drive signal, and making the absolute value of the number difference corresponding to each target row is less than or equal to the preset number, the adjusted (k+1)-th frame data drive signal can then be output to the liquid crystal display panel to drive the solid pixels to light up, so as to display the picture of the (k+1)-th frame.
As shown in
In one embodiment, the drive method further includes:
In the application, the user can terminate the polarity adjustment step at any time according to the actual needs (for example, when the user determines that the pictures displayed by the liquid crystal display panel in a next period of time are pictures with the grayscale value being less than or equal to the preset grayscale value). Thus, when the processor of the liquid crystal display apparatus receives the image data used to drive the liquid crystal display panel to display the picture of a next frame, it can directly drive the liquid crystal display panel to display the picture of the (k+1)-th frame according to the image data of the (k+1)-th frame, which simplify the driving process and improve the driving efficiency.
