Referring to fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, a display panel and a display device thereof according to an embodiment of the present application will be described in detail with reference to the drawings.
The display panel aims to solve the problem that the quality of a large viewing angle is poor and the display effect of a panel picture is influenced in a double-gate structure of a traditional display panel. In one embodiment, as shown in fig. 1, there is provided a display panel including:
a plurality of sub-pixels arranged in a matrix, the plurality of sub-pixels being divided into a plurality of pixel sub-regions arranged repeatedly along rows and columns; any pixel sub-area comprises a plurality of sub-pixels arranged in a 6-column 4M-row matrix, wherein M is a positive integer; in the pixel sub-area, sequentially dividing 6 columns of sub-pixels into three groups of sub-pixel combinations; the sub-pixel combination comprises a first column of sub-pixels and a second column of sub-pixels which are adjacent;
the data lines are respectively used for transmitting data signals, one data line is arranged between a first row of sub-pixels and a second row of sub-pixels in each sub-pixel combination, and the first row of sub-pixels and the second row of sub-pixels are connected to the data lines in a staggered mode; the sub-pixels connected with the same data line are subjected to polarity arrangement based on a single-four-wire polarity inversion driving mode;
in the pixel sub-area, gray scale pretreatment is respectively carried out on data signals transmitted by each data line, so that the gray scale of any sub-pixel is different from that of the adjacent sub-pixels.
Specifically, the respective sub-pixels are arranged based on a matrix arrangement rule, and the respective sub-pixels in the matrix arrangement may form at least one pixel sub-area. The sub-pixel sub-area comprises 6 columns of sub-pixels with 4M rows, and the 6 columns of sub-pixels in the same sub-pixel sub-area can be divided into three groups of sub-pixel combinations based on the left-to-right direction, that is, each group of sub-pixel combinations comprises 2 columns of sub-pixels (that is, a first column of sub-pixels and a second column of sub-pixels). The first column of sub-pixels may include 4M sub-pixels, and the colors of the 4M sub-pixels are the same; the second column of sub-pixels may include 4M sub-pixels, and the 4M sub-pixels are all the same color. In one example, the sub-pixels of the first column of sub-pixels and the second column of sub-pixels are different colors.
Furthermore, a data line is arranged between the first column of sub-pixels and the second column of sub-pixels in each sub-pixel combination, so that in the column direction, each group of sub-pixel combinations only comprises one data line, namely, one data line is arranged between the first column of sub-pixels and the second column of sub-pixels contained in the sub-pixel combinations; and no data line is arranged between the adjacent sub-pixel combinations. In the sub-pixel combination, the sub-pixels of the first column and the sub-pixels of the second column are connected on the same data line in a staggered mode. In one example, each sub-pixel included in the first column of sub-pixels may be connected on the data line based on an odd bit; the subpixels of the second column of subpixels may be connected on the same data line based on the even bits. For example, the first column of sub-pixels includes 2 sub-pixels, the second column of sub-pixels includes 2 sub-pixels, one sub-pixel of the first column of sub-pixels is connected to the first bit of the data line, one sub-pixel of the second column of sub-pixels is connected to the second bit of the data line, the other sub-pixel of the first column of sub-pixels is connected to the third bit of the data line, the other sub-pixel of the second column of sub-pixels is connected to the fourth bit of the data line, and the connection relationship of the sub-pixels on the other data lines is analogized in turn, so that the sub-pixels included in the first column of sub-pixels and the sub-pixels included in the second column of sub-pixels are connected to the same data line in an interlaced manner.
Furthermore, the sub-pixels connected based on the same data line are arranged in a polarity mode based on single four-wire polarity inversion (1+4line), namely, the polarity of the sub-pixel connected to the head of the same data line in the sub-pixels connected to the same data line is a first polarity; the polarities of the sub-pixels connected by four bits after the first bit of the data line are the same, and the sub-pixels connected by four bits are all of the second polarity; and then the polarities of the sub-pixels connected with the same data line by four bits are the same, the sub-pixels connected by the four bits are all of the first polarity, and so on, thereby realizing the driving mode of each sub-pixel connected by the same data line based on single four-wire polarity inversion (1+4 line).
For example, in the pixel sub-area, the polarity of the sub-pixels located in the first row and the first column is positive, and the polarities of the sub-pixels located in the first row and the second column, the second row and the first column, the second row and the second column, and the third row and the first column are negative; the polarities of the sub-pixels in the third row, the second column, the fourth row, the first column, the second column and the fifth row, and the polarities of the sub-pixels in other columns are all positive, and so on, and are not described again.
Further, based on the structure and polarity arrangement of each pixel sub-area, after the viewing angle compensation is started, gray scale preprocessing can be performed on the data signals transmitted by each data line respectively, so that the gray scale of any sub-pixel is different from the gray scale of the adjacent sub-pixel.
It should be noted that, the gray scale of any sub-pixel in the sub-area of the pixel may be different from the gray scale of the adjacent sub-pixel based on the high-low gray scale mapping. For example, if the gray level of any sub-pixel is high, the gray level of the adjacent sub-pixel is low.
Specifically, the method includes dividing a plurality of sub-pixels into a plurality of pixel sub-regions repeatedly arranged along rows and columns; any pixel sub-area comprises a plurality of sub-pixels arranged in a 6-column 4M-row matrix, wherein M is a positive integer; in the pixel sub-area, sequentially dividing 6 columns of sub-pixels into three groups of sub-pixel combinations; the sub-pixel combination comprises a first column of sub-pixels and a second column of sub-pixels which are adjacent; each data line is respectively used for transmitting data signals, a data line is arranged between a first row of sub-pixels and a second row of sub-pixels in each sub-pixel combination, and the first row of sub-pixels and the second row of sub-pixels are connected to the data lines in a staggered mode; the sub-pixels connected with the same data line are subjected to polarity arrangement based on a single-four-wire polarity inversion driving mode; in the pixel sub-area, gray scale pretreatment is respectively carried out on data signals transmitted by each data line, so that the gray scale of any sub-pixel is different from that of the adjacent sub-pixel, the chromaticity visual angle of the display panel is improved, and the image display quality of the panel is improved.
In the above embodiment, the sub-pixels and the data lines are arranged, the sub-pixels connected to the same data line are arranged in a polarity manner based on a single-line and four-line polarity inversion driving method, and the gray scale of the data signal transmitted by each data line is respectively preprocessed, so that the gray scale of any sub-pixel is different from that of an adjacent sub-pixel, thereby reducing the cost of the whole product and improving the chromaticity and viewing angle of the display panel.
In one example, the display panel further includes a plurality of scan lines (not shown), and each scan line is vertically staggered with each data line. In each pixel sub-area, two sides of each row of sub-pixels are respectively provided with a scanning line, namely, one side of the first row of sub-pixels, which is far away from the second row of sub-pixels, is provided with a scanning line, one side of the 4M-th row of sub-pixels, which is far away from the 4M-1 th row of sub-pixels, is provided with a scanning line, and two scanning lines are arranged between the two rows of sub-pixels. Each scan line may be used to transmit a scan signal.
For example, the sequence of the scan lines from top to bottom is defined as the first scan line to the 4M scan line. In the sub-pixel area, the sub-pixels in the first row and the first column (i.e. the sub-pixels included in the first column of sub-pixels of a sub-pixel combination) are connected with the first scan line, and the sub-pixels in the second row and the second column (i.e. the sub-pixels included in the second column of sub-pixels of a sub-pixel combination) are connected with the second scan line. The sub-pixels in the first column of the second row (i.e. the sub-pixels included in the first column of the sub-pixel combination) are connected to the third scanning line, and the sub-pixels in the second column of the second row (i.e. the sub-pixels included in the second column of the sub-pixel combination) are connected to the fourth scanning line. The sub-pixels in the first row and the third column (i.e. the sub-pixels included in the first column of sub-pixels of another sub-pixel combination) are connected with the second scanning line, and the sub-pixels in the first row and the fourth column (i.e. the sub-pixels included in the second column of sub-pixels of another sub-pixel combination) are connected with the first scanning line. The sub-pixels in the second row and the third column (i.e. the sub-pixels in the first column of the other sub-pixel combination) are connected to the fourth scanning line, and the sub-pixels in the second row and the fourth column (i.e. the sub-pixels in the second column of the other sub-pixel combination) are connected to the third scanning line. The connection mode of the first column of sub-pixels and the second column of sub-pixels included in other sub-pixel combinations is similar, and the description is omitted here.
In one example, in the sub-pixel combination, each sub-pixel included in the sub-pixel of the first column is further provided with a first Thin Film Transistor (TFT); each sub-pixel included in the second row of sub-pixels is also provided with a second thin film transistor respectively. Assume that the directions of the scan lines from top to bottom are divided into the odd scan line and the even scan line. The grid electrode of the first thin film transistor is connected to the corresponding odd-numbered scanning line, the source electrode of the first thin film transistor is connected with the corresponding data line, and the drain electrode of the first thin film transistor is connected with the corresponding sub-pixel. The grid electrode of the second thin film transistor is connected to the corresponding even number scanning line, the source electrode is connected with the corresponding data line, and the drain electrode is connected with the corresponding sub-pixel. And the corresponding scanning line can transmit a scanning signal to the first thin film transistor, and then the first thin film transistor is conducted, so that the data signal of the corresponding data line is transmitted to the corresponding sub-pixel through the first thin film transistor. Similarly, the corresponding scan line can transmit a scan signal to the second thin film transistor, and the second thin film transistor is turned on, so that the data signal of the corresponding data line is transmitted to the corresponding sub-pixel through the second thin film transistor.
In one embodiment, in the pixel sub-area, each sub-pixel of one column is a red sub-pixel, a blue sub-pixel or a green sub-pixel.
For example, in the pixel sub-area, the color of each sub-pixel in the same column is the same, as shown in fig. 2, the sub-pixel in the first column is a red sub-pixel, the sub-pixel in the second column is a blue sub-pixel, and the sub-pixel in the third column is a green sub-pixel.
In one embodiment, in the pixel sub-area, the arrangement of the sub-pixels of each column is sequentially red sub-pixels, blue sub-pixels and green sub-pixels.
Specifically, as shown in fig. 2, in the pixel sub-area, the sub-pixels in each column are sequentially a red sub-pixel, a blue sub-pixel and a green sub-pixel based on the arrangement from the left to the right. For example, each sub-pixel of the first column of sub-pixels is a red sub-pixel, each sub-pixel of the second column of sub-pixels is a green sub-pixel, each sub-pixel of the third column of sub-pixels is a blue sub-pixel, and so on.
In one embodiment, based on the large-viewing-angle algorithm, the data signals transmitted by the data lines are subjected to bright and dark adjustment processing, so that the original gray scale of any sub-pixel is replaced by a high gray scale and a low gray scale mapping.
Specifically, based on the structure and polarity arrangement of each pixel sub-area, and a large viewing angle algorithm is matched to improve the chromaticity viewing angle. It should be noted that, in the large viewing angle algorithm, the sub-pixels are used as units, and the bright and dark processing is performed on the data signals input to the data lines, so that the chromaticity viewing angle is improved.
In one embodiment, a high gray scale and a low gray scale of the corresponding sub-pixel are obtained on the front-view Gamma curve; wherein the average value of the brightness between the high gray scale and the low gray scale is equal to the brightness value of the original gray scale of the corresponding sub-pixel.
Specifically, the large viewing angle algorithm processes the data signals input to the data lines without changing the original display brightness. For example, in the sub-area of the pixel, any sub-pixel is selected, and a high gray scale and a low gray scale of the sub-pixel are obtained on the front-view Gamma curve, so that the average value of the brightness between the high gray scale and the low gray scale is equal to the brightness value of the original gray scale of the corresponding sub-pixel.
In one example, assuming that the first row and first column of sub-pixels in the sub-pixel region are red sub-pixels, taking the display of 128 gray levels of the first row and first column of red sub-pixels as an example, a pair of red high and low gray levels HL (i.e., the high gray level is H and the low gray level is L) is found on the front view Gamma curve, and the average value of the luminance of the pair of red high and low gray levels HL is equal to the luminance value of the original red 128 gray level. The green sub-pixel and the blue sub-pixel are processed by the same method to obtain a corresponding pair of green high-low gray scale HL values and a corresponding pair of red high-low gray scale HL values.
Further, as shown in fig. 3 and 4, taking the first row, the first column of red subpixels and the seventh row of red subpixels as an example, the first row, the first column of red subpixels are high gray-scale subpixels, and the seventh row of red subpixels are low gray-scale subpixels. Wherein, the gray scale values of the two original red sub-pixels are the same, and the original gray scale is mapped by a high gray scale and a low gray scale. In one example, the matching of the high and low gray levels can be performed by the timing controller by looking up the high and low gray level representations.
In one example, as shown in fig. 5 and 6, by arranging the sub-pixels and the data lines, and arranging the sub-pixels connected to the same data line based on a single four-line polarity inversion driving method, and based on the high-low gray scale mapping, after the viewing angle compensation is turned on, for example, it is assumed that the HL values after processing the three colors of RGB are the same (H is 180, L is 30, and in practice, the HL values of RGB are not necessarily the same). In the first red sub-pixel of the first column of red sub-pixels, the data signal of the data line D1 jumps from +180 gray scale to +30 gray scale, so that the first red sub-pixel of the first column of red sub-pixels is coupled and darkened; in the first red sub-pixel of the fourth row of red sub-pixels, the data signal of the data line D2 jumps from the-30 gray level to the +180 gray level, so that the first red sub-pixel of the fourth row of red sub-pixels is coupled to be brighter. In the first green sub-pixel of the second row of green sub-pixels, the data signal of the data line D1 jumps from the gray scale of-30 to the gray scale of-180, so that the first green sub-pixel of the second row of green sub-pixels is coupled and darkened; in the first green sub-pixel of the fifth row of green sub-pixels, the data signal of the data line D3 jumps from the-180 gray level to the-30 gray level, so that the first green sub-pixel of the fifth row of green sub-pixels is coupled to be brightened. The other sub-pixels are analogically arranged, so that for example, the first red sub-pixel in the first row becomes bright and the first red sub-pixel in the fourth row becomes dark, and the first green sub-pixel in the second row becomes bright and the first green sub-pixel in the fifth row becomes dark, so that the chromaticity viewing angle of the display panel can be improved, and the panel picture display quality is improved.
In one embodiment, in each sub-pixel connected to the same data line, the first sub-pixel is a group and the polarity is a first polarity based on the connection order of the sub-pixels, and then four sub-pixels are a group and driven with the same polarity and driven with the opposite polarity to the previous group.
Specifically, each sub-pixel in the same sub-pixel combination is connected with the same data line, that is, the sub-pixels in the first column and the sub-pixels in the second column in the same sub-pixel combination are both connected with the same data line. Based on the connection order of the sub-pixels of the data lines from top to bottom, the polarity of the first sub-pixel connected to the data line can be set as a first polarity, and the first sub-pixel is defined as a group; after the first sub-pixel, taking four sub-pixels which are continuously connected on the data line as a group, and setting each sub-pixel of the group to be in a second polarity; after the four sub-pixels of the previous group, the four sub-pixels connected to the data line are grouped into a group, and each sub-pixel of the group is set to the first polarity, and so on, so that the four sub-pixels are grouped into a group with the same polarity and driven with the opposite polarity to the previous group.
In one embodiment, the polarities of the leading subpixels of adjacent data lines are opposite.
For example, as shown in fig. 5, if the polarity of the first sub-pixel (i.e., the first sub-pixel) connected to the data line D1 is positive, the polarity of the first sub-pixel connected to the data line D2 is negative, the polarity of the first sub-pixel connected to the data line D3 is positive, and so on, the polarities of the first sub-pixels of the adjacent data lines are opposite.
In one embodiment, as shown in fig. 3 and 4, the high-low gray level map is set to HLHL, i.e. the gray level of any sub-pixel is high gray level H, and the gray level of the adjacent sub-pixel is low gray level L. The sub-pixels and the data lines are arranged, the sub-pixels connected with the same data line are subjected to polarity arrangement based on a single-four-line polarity inversion driving mode, the high-low gray scale mapping is set to be HLHL, the image quality of the display panel can be improved, the number of + H and-H of the sub-pixels of each color on two adjacent lines is the same, the number of + L and-L is the same, and therefore the risk of dot shading is reduced. In the period unit, the number of + H and-H in a single frame is the same, and the number of + L and-L is also the same, so that the flicker risk is reduced. The numbers of + H and-H and the numbers of + L and-L of the sub-pixels of each color in the two adjacent columns of pixels are the same, so that the risk of shaking the head is reduced. The degree of positive and negative coupling (manifold) between the Data signal (Data) change of the Data line and the common electrode coupling (VCOM manifold) can be offset, so that the risk of high gray level crosstalk (H crosstalk) is low. The orientation of liquid crystal molecules in the 4-domain liquid crystal panel with the double-gate pixel structure is further enriched, so that the chromaticity and the visual angle of the display panel are improved.
Here, + H denotes a positive polarity high gray level; -H refers to negative polarity high gray level; + L refers to positive polarity low gray level; -L refers to negative polarity low gray level.
