detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiments of the present invention will be described in detail below in conjunction with the following drawings.

An embodiment of the present invention provides a method for driving a liquid crystal panel. The liquid crystal panel includes a plurality of pixel units, a gate drive unit, and a data drive unit, and uses a frame inversion driving method to display graphics. The frame inversion includes several subframes Unit inversion, the sub-frame unit includes at least one pixel unit in the liquid crystal panel, the sub-frame unit inversion is used to control the sub-frame unit through the data drive unit under the control of the gate drive unit The polarity of each pixel unit in the liquid crystal panel is reversed once after a frame inversion process is completed.

It should be noted that the liquid crystal panel achieves the effect of changing the displayed image by driving the arrangement of the liquid crystal molecules to change. Therefore, in order to prevent the liquid crystal molecules from being degraded by twisting the liquid crystal molecules for a long time, the liquid crystal panel generally uses an alternating voltage to drive the liquid crystal molecules. As a driving method of the liquid crystal panel, the frame inversion driving method can be specifically described as: if all the pixel units of the liquid crystal panel in the previous frame output data of a certain polarity, all the pixel units of the liquid crystal panel in the next frame will output data of the opposite polarity data and loop through them sequentially. Wherein, the polarity of the pixel unit refers to the polarity of the pixel voltage of the pixel unit relative to the common electrode voltage, including two types of positive polarity and negative polarity. For example, as shown in Figures 1 and 2, taking a liquid crystal panel including four rows and four columns of pixels as an example, the frame inversion driving method can be described as: in the first frame, all pixel units of the liquid crystal panel output as shown in Figure 1 For positive polarity data, all pixel units of the liquid crystal panel in the second frame output negative polarity data as shown in Figure 2, and all pixel units of the liquid crystal panel in the third frame output positive polarity data as shown in Figure 1. All pixel units of the panel output negative polarity data as shown in FIG. 2 , .

As a specific embodiment of the present invention, the above-mentioned first frame and second frame of the liquid crystal panel are described as a complete frame inversion process as an example, and several sub-frames are set in the frame inversion process The unit is reversed. In order to describe the embodiment of the present invention simply and clearly, it is taken as an example that two subframe unit inversions are set in the frame inversion process. As shown in Figure 3, the liquid crystal panel includes a plurality of pixel units, a gate drive unit and a data drive unit, and adopts the frame inversion driving mode to display graphics. The schematic diagram of the first frame of the liquid crystal panel can be referred to as shown in S101 in Figure 3. First, The liquid crystal panel starts the first subframe unit inversion at time t1 after the start of the first frame, wherein the first subframe unit inversion is used to drive at least one of the liquid crystal panels through the data drive unit under the control of the gate drive unit. The polarity of the pixel unit is reversed. For example, the pixel unit of the first subframe unit reversal includes the pixel unit located at the intersection of odd rows and odd columns and the pixel unit located at the intersection of even rows and even columns, while the liquid crystal The polarity of the pixel units at other positions in the panel remains unchanged, and at this time, the liquid crystal panel after the first subframe unit inversion is shown as S102 in FIG. 3 . Then, after the first subframe unit inversion is completed, the liquid crystal panel starts the second subframe unit inversion at the time t2 after the first frame starts, wherein the second subframe unit inversion is used in the gate drive unit Under the control of the data driving unit, the polarity of at least one pixel unit in the liquid crystal panel is reversed. For example, the pixel unit of the second subframe unit inversion includes the pixel unit located at the intersection of the odd row and the even column and the pixel unit located at the even column. The polarity of the pixel unit at the intersection of the row and the odd column, while the polarity of the pixel unit at the other positions in the liquid crystal panel remains unchanged. At this time, the liquid crystal panel after the second subframe unit inversion is shown as S103 in FIG. 3 . After the first subframe unit inversion and the second subframe unit inversion, the liquid crystal panel completes a frame inversion process. It should be noted that each pixel unit in the liquid crystal panel undergoes a polarity inversion after a frame inversion process is completed.

Compared with the frame inversion driving method in the prior art, several times of subframe unit inversions are set during one frame inversion process of the liquid crystal panel in the embodiment of the present invention, and the subframe unit includes at least one pixel unit in the liquid crystal panel, Subframe unit inversion includes inverting the polarity of the subframe unit. Therefore, in the embodiment of the present invention, the pixels of the liquid crystal panel are reversed multiple times by subframe units instead of inverting all pixel units at one time within one frame period. The possibility of flickering and data crosstalk in the liquid crystal panel of the embodiment of the present invention is reduced, and the display effect of the liquid crystal panel is improved.

It should be noted that, first, in the above specific implementation manner, if the start time of the first frame is defined as time 0, and the start time of the second frame is defined as time T, then those skilled in the art can understand that the first subframe The unit inversion time t1 and the second subframe unit inversion time t2 should satisfy: 0<t1<t2≤T. Second, in the above-mentioned specific implementation manners, the description about the first sub-frame unit inversion and the reversed pixel units in the second sub-frame unit inversion process is only an exemplary description. In fact, in the above-mentioned embodiment There are many possible situations for the pixel unit of the first subframe unit inversion and the pixel unit of the second subframe unit inversion, for example: the first subframe unit inversion includes the position where the odd row and the even column intersect The pixel unit at and the pixel unit at the intersection of even rows and odd columns, the second subframe unit inversion includes the pixel units at the intersection of odd rows and odd columns and the pixel unit at the intersection of even rows and even columns pixel unit. The only certainty is that, regardless of the possible situation of the pixel units included in the first sub-frame unit inversion and the pixel units included in the second sub-frame unit inversion, each pixel unit of the liquid crystal panel in a frame A polarity reversal is performed after the reversal process is complete.

As another possibility of the present invention, an embodiment of the present invention proposes another liquid crystal panel driving method. The working background of the liquid crystal panel driving method in this embodiment can refer to the above embodiments, and will not be repeated here. The difference is that in this specific embodiment, four subframe unit inversions are set during one frame inversion process. Similarly, the first frame of the liquid crystal panel with four rows and four columns and the second frame of the liquid crystal panel with four rows and four columns are used as a frame inversion process. First, the schematic diagram of the liquid crystal panel at the moment of the first frame is shown in S111 in Figure 4. The liquid crystal panel The first subframe unit inversion starts at the time t1' after the start of the first frame, wherein the first subframe unit inversion reverses the polarity of at least one pixel unit in the liquid crystal panel, for example, the first subframe The pixel unit of the unit inversion includes the pixel unit at the intersection of the odd row and the odd column, and the polarity of the pixel unit included in the first subframe unit is reversed, while the polarity of the pixel unit at the remaining positions in the liquid crystal panel remains In this case, the liquid crystal panel after the completion of the first subframe unit inversion is shown in S112 in Figure 4; then, after the first subframe unit inversion is completed, the liquid crystal panel will Start the second sub-frame unit inversion, wherein the second sub-frame unit inversion reverses the polarity of at least one pixel unit in the liquid crystal panel, for example, the second sub-frame unit inversion includes pixel units located in odd rows For the pixel unit at the intersection with the even-numbered column, the polarity of the pixel unit included in the second subframe unit is reversed, while the polarity of the pixel unit at the remaining positions in the liquid crystal panel remains unchanged. At this time, the second subframe unit The liquid crystal panel after the unit inversion is completed is shown in S113 in Figure 4; then after the second subframe unit inversion is completed, the liquid crystal panel starts the third subframe unit inversion at time t3' after the first frame starts , wherein the third subframe unit inversion reverses the polarity of at least one pixel unit in the liquid crystal panel, for example, the pixel unit of the third subframe unit inversion includes the pixel unit at the intersection of the even row and the odd column , the polarity of the pixel units included in the third sub-frame unit is reversed, while the polarities of the pixel units at other positions in the liquid crystal panel remain unchanged. At this time, the liquid crystal panel after the third sub-frame unit inversion is as follows: As shown in S114 in Fig. 4; then after completing the third subframe unit inversion, the liquid crystal panel starts the fourth subframe unit inversion at the time t4' after the first frame begins, wherein the fourth subframe unit inversion The polarity of at least one pixel unit in the liquid crystal panel is reversed. For example, the pixel unit of the fourth sub-frame unit inversion includes the pixel unit at the intersection of the even-numbered row and the even-numbered column, and the fourth sub-frame unit includes The polarity of the pixel unit of the sub-frame is reversed, while the polarity of the pixel unit at other positions in the liquid crystal panel remains unchanged. At this time, the liquid crystal panel after the fourth sub-frame unit inversion is shown as S115 in FIG. 4 . Through the first subframe unit inversion, the second subframe unit inversion, the third subframe unit inversion and the fourth subframe unit inversion, the liquid crystal panel completes a frame inversion process. The polarity of each pixel unit is reversed once after a frame inversion process is completed. Among them, the analysis shows that in this specific embodiment, if the first frame start time is defined as 0 time, and the second frame start time is defined as T time, then the first subframe unit inversion time t1', the second time The subframe unit inversion time t2', the third subframe unit inversion time t3' and the fourth subframe unit inversion time t4' should satisfy: 0<t1'<t2'<t3'<t4'≤T . According to the polarity inversion method of the liquid crystal panel as shown in FIG. 4 , the connection method of the pixel units of the liquid crystal panel included in the subframe unit corresponding to the inversion of each subframe unit can be implemented with reference to the connection method shown in FIG. 5 .

It should be noted that after a frame inversion process is completed, each pixel unit in the liquid crystal panel undergoes a polarity inversion. In the specific implementation process, no matter how many sub-frame unit inversions are set and which pixel units are included in the sub-frame unit, the implementation process should be considered as included in the present invention.

In addition, it should be noted that the above description about the polarity refers to the polarity of the pixel voltage of the pixel unit included in the sub-frame unit relative to the common electrode voltage, so those skilled in the art can understand that the pixel included in the sub-frame unit The polarity inversion of the cell includes two possible situations: the polarity of the pixel voltage changes from positive polarity relative to the common electrode voltage to negative polarity relative to the common electrode voltage or the polarity of the pixel voltage changes from positive polarity relative to the common electrode voltage Negative polarity changes to positive polarity with respect to the common electrode voltage.

Further, the inversion time intervals of adjacent subframe units are the same. The purpose of setting the same inversion time interval of adjacent subframe units is to simplify the control process of driving the liquid crystal panel, so it is a more preferable choice for adjacent subframe unit inversion time intervals to be the same.

Further, the pixel units of the liquid crystal panel included in the sub-frame unit are not adjacent to each other. It should be noted that the sub-frame unit includes at least one pixel unit in the liquid crystal panel. If the pixel units included in the sub-frame unit are adjacent, the adjacent pixel units may affect each other when the polarity is reversed, resulting in flicker and data loss. Crosstalk occurs, therefore, it is a more preferable choice that the pixel units of the liquid crystal panel included in the sub-frame unit are not adjacent to each other.

Further, the polarity of the sub-frame unit is the polarity of the pixel voltage of the pixel unit included in the sub-frame unit relative to the common electrode voltage.

In the liquid crystal panel driving method provided by the embodiment of the present invention, several times of subframe unit inversion are set in the frame inversion, the subframe unit includes at least one pixel unit in the liquid crystal panel, and the subframe unit inversion includes inverting the subframe unit The polarity of each pixel unit in the liquid crystal panel is reversed once after a frame inversion process is completed, thereby reducing flicker and crosstalk in the liquid crystal panel, and improving the display effect of the liquid crystal panel and the display device.

Further, as a specific implementation manner of the embodiment of the present invention, as shown in FIG. 5 to FIG. 7 , the liquid crystal panel includes gate lines 1, data lines 2, thin film transistors 3, pixel units 4, gate drive units 5. Data drive unit 6, etc., each pixel unit 4 is connected to a thin film transistor 3, wherein the first row of gate lines is connected to the odd-numbered column thin film transistors of the first row of pixel units, and the last row of gate lines is connected to the even-numbered columns of the last row of pixel units. The thin film transistors in the same row are connected, and the gate lines of the remaining rows are connected with the thin film transistors in the odd columns of the pixel units in the row, and the gate lines of the remaining rows are connected with the thin film transistors in the even columns of the pixel units in the adjacent row, and the pixel units connected with the gate lines of the odd rows are the first A sub-frame unit, the pixel unit connected to the even-numbered row of gate lines is the second sub-frame unit. Frame inversion includes first subframe unit inversion and second subframe unit inversion.

For example, taking the liquid crystal panel shown in FIG. 5 as an example, the working process of the liquid crystal panel can be understood as: the gate drive unit 5 is used to provide a control signal, and the control signal turns on the corresponding thin film transistor 3 through the gate line 1, Then the data driving unit 6 is used to provide display data, which is transmitted to the pixel unit 4 through the data line 2 for image display. The displayed data includes data information and the positive and negative polarity information of the data. In order to understand the embodiment of the present invention more easily, the specific situation of the data information is not considered here, and only the positive and negative polarities of the data are used for description.

It should be noted that due to the different designs of liquid crystal panels, there are many possible situations in which the gate lines, data lines, thin film transistors, and pixel units are connected. Therefore, in the sub-frame driving process of the liquid crystal panel, not only the driving timing of the liquid crystal panel must be considered, but also the influence of the connection mode of the gate lines, data lines, thin film transistors and pixel units in the liquid crystal panel on the driving timing. The way should correspond to the control timing to achieve the purpose of sub-frame driving. The structure of the liquid crystal panel as shown in FIG. 5 to FIG. 7 and the description of the relevant driving sequence in this embodiment are only for those skilled in the art to facilitate understanding of the embodiment of the present invention, and are not intended to further limit the present invention.

Specifically, taking a liquid crystal panel including four rows of gate lines and four columns of data lines as an example, as shown in FIG. The polarities are all positive; the liquid crystal panel is driven in the frame inversion driving mode, and the frame inversion includes the inversion of the first subframe unit and the inversion of the second subframe unit, wherein the first subframe unit is connected to the gate lines of odd rows pixel units, and the second sub-frame unit is a pixel unit connected to an even-numbered row of gate lines. Firstly, the liquid crystal panel starts to invert the unit of the first subframe at time t1 after the start of the first frame. Combining with the liquid crystal panel shown in FIG. 5 , the driving process of the liquid crystal panel can be described as: , the gate drive unit 5 provides a control signal to control and turn on the thin film transistors 3 connected to the gate lines 1 in odd rows, and the data drive unit 6 provides negative polarity data information. Therefore, the first sub-frame unit receives the negative polarity data information and undergoes polarity inversion, while the pixel units at other positions remain unchanged. At this time, the liquid crystal panel is shown in FIG. 6 .

Then, the liquid crystal panel starts the second subframe inversion at time t2 after the start of the first frame. In combination with the liquid crystal panel shown in FIG. The gate driving unit 5 provides a control signal to control to turn on the thin film transistors 3 connected to the gate lines 1 of even rows, and the data driving unit 6 provides data information of negative polarity. Therefore, the second sub-frame unit receives negative polarity data information and reverses the polarity, while the pixel units at other positions remain unchanged. At this time, the liquid crystal panel is shown in FIG. 7 . After the unit inversion of the first subframe and the inversion of the second subframe unit, the liquid crystal panel completes a frame inversion process.

It should be noted that each pixel unit in the liquid crystal panel undergoes a polarity inversion after a frame inversion process is completed. Those skilled in the art can understand that the above description about the structure of the liquid crystal panel is only for easier understanding of the liquid crystal panel driving method of the embodiment of the present invention, rather than further limiting the present invention. In fact, the liquid crystal panel of the embodiment of the present invention The structure can be adjusted by the staff according to actual needs, so I won't go into details here.
