Description

Display panel and driving method thereof

Technical Field

The present invention relates to a display panel, and more particularly, to a display panel using a polarity inversion driving method.

Background

With the development of science and technology, the resolution requirement of a display panel is relatively improved, there are two main methods for improving the panel chromaticity and viewing angle in the prior art, and the first method is an innovative design of the display panel, for example: a multi-quadrant vertical alignment technique; the second method is a pre-processing of the input data, i.e. a light/dark (H/L) processing of the sub-pixels. The second method can achieve the improvement of the chroma visual angle at a lower cost compared with the high cost requirement of the first method, but the reasonable matching between the driving mode and the data image is the key for achieving the improvement of the chroma visual angle.

Referring to fig. 1 and fig. 2, two conventional driving methods are respectively shown, and the polarities of the

sub-pixels

110, 111, 112, and 113 in the horizontal direction of the display panel 10 driven by the first driving method shown in fig. 1 are respectively set as: positive, negative, positive, the polarities of the

sub-pixels

110, 116, 117, 118 in the vertical direction are set as: the 1+2 rows are inverted and the data map is light and dark (where dark is indicated by diagonal lines). The polarities of the

sub-pixels

210, 211, 212, 213 in the horizontal direction of the display panel 20 driven by the second driving method shown in fig. 2 are set as: positive polarity, negative polarity, the polarities of the

subpixels

210, 216, 217, 218 in the vertical direction are set as: the rows are reversed and the data map is light, dark (where dark is indicated by diagonal lines).

The two driving modes have different display defects, the switching of the positive polarity and the negative polarity on the same data line in the first driving mode is very frequent, the load of a driver is increased, the power consumption is increased, bright and dark lines are easy to generate, the granular sensation is aggravated after the data signals are processed by the second driving mode, the problem of crosstalk can occur, and the driving mode is only suitable for being used on a panel with 8k or higher resolution and is not suitable for a 4k panel.

In addition, there are a lot of coupling capacitors between the data traces, the electrodes and the tfts of the lcd panel, and the coupling capacitors can cause many display problems, such as: the voltage on the pixel electrode also generates a feed-through voltage, resulting in non-uniform brightness of the image display.

In an embodiment of the present invention, the voltage of the common electrode may be selected from a voltage value of the common electrode on the color filter substrate, and a voltage value of the common electrode on the array substrate. So that the design of the corresponding driving circuit is more flexible.

A plurality of sub-pixels (e.g., sub-pixels 421 to 439) are arranged in a matrix, each sub-pixel is selected from a group consisting of a first sub-pixel, a second sub-pixel and a third sub-pixel, and three

sub-pixels

421, 422 and 423 in each pixel 41 are different from each other and are arranged in sequence. Each of the sub-pixels (e.g., sub-pixels 421 to 439) corresponds to one color, and in an embodiment of the present invention, the first sub-pixel is a red sub-pixel, the second sub-pixel is a green sub-pixel, and the third sub-pixel is a blue sub-pixel. In an embodiment of the present invention, 6 red sub-pixels, 5 green sub-pixels, and 4 blue sub-pixels are repeatedly arranged in the row direction in the order of red (R), green (G), and blue (B). Each data line is connected to the sub-pixels in the same column. In an embodiment of the present invention, the sub-pixels 421, 424, 427, 430, 433, 436 and the sub-pixels in the vertical direction thereof are first sub-pixels, for example: the red sub-pixel, sub-pixels 422, 425, 428, 431, 434 and the sub-pixels in the vertical direction thereof are the second sub-pixels, for example: the green sub-pixel, sub-pixels 423, 426, 429, 432, 435 and the sub-pixel in the vertical direction thereof are the third sub-pixel, for example: a green sub-pixel.

Referring to fig. 4A and 4B, all the sub-pixels (e.g., the sub-pixels 421 to 439) in the display panel 40 are arranged in a matrix to form N columns of sub-pixels and M rows of sub-pixels, where N and M are integers, the sub-pixels are divided into a first area 410, a second area 411, a third area 412 and a fourth area 413, and each of the areas 410 to 413 includes a plurality of sub-pixels arranged in a 4 × M matrix; the polarities of the first row of sub-pixels in the first and

fourth regions

410 and 413 are set to a first polarity arrangement, and the polarities of the first row of sub-pixels in the second and

third regions

411 and 412 are set to a second polarity arrangement; in the first polarity arrangement, as shown in the polarity arrangement of the sub-pixels 421, 422, 423, 424 in the first row in the first region 410, the polarities of the adjacent sub-pixels are opposite to each other. The second polarity arrangement is reversed from the first polarity arrangement as shown by the polarity arrangement of the

subpixels

425, 426, 427, 428 of the first column in the second area 411. The sub-pixel set to the positive polarity is driven by the positive voltage, and the sub-pixel set to the negative polarity is driven by the negative voltage.

In an embodiment of the invention, when the display panel has N data lines connecting N columns of sub-pixels and M rows of sub-pixels, the N columns of sub-pixels are divided into 4K area groups, each area group has K areas (i.e., a first area 410, a second area 411, a third area 412, and a fourth area 413) as shown in fig. 4A and 4B, and each area 410 to 413 includes a plurality of sub-pixels arranged in a 4 × M matrix. For example: when the resolution is 4096 × 2160, there are 4096 × 3 subpixels in each column of subpixels, 2160 subpixels in each row of subpixels, i.e., N equals 4096 × 3, M equals 2160, the division into 768 area groups, 3072 areas, i.e., 4K equals 768, K equals 3072, and thus each area in each area group has a plurality of subpixels arranged in a 4 × 2160 matrix.

In an embodiment of the present invention, the first polarity arrangement is sequentially positive polarity, negative polarity, positive polarity, and negative polarity, the second polarity arrangement is sequentially negative polarity, positive polarity, negative polarity, and positive polarity, a plurality of sub-pixels on the same column (e.g., the sub-pixels 421, 437, 438, and 439 of the first column in the first area 410) in each area all have the same polarity, the sub-pixels of each column carry the opposite polarity to that of the odd frame (e.g., the first frame) in the even frame (e.g., the second frame), as shown in fig. 4A and 4B, "+" represents sub-pixels having a positive voltage with respect to the common voltage, "-" represents sub-pixels having a negative voltage with respect to the common electrode voltage, under the control of the polarity control signal, the polarities of any adjacent sub-pixels are opposite, and the polarities of each sub-pixel in any adjacent two frames are opposite, the polarities of the sub-pixels (for example, the sub-pixels 421, 437, 438, and 439 in the 1 st column of fig. 4A) arranged in the vertical direction (i.e., in the same column) are the same, so that the problem that the switching of the positive polarity and the negative polarity on the same data line is very frequent is solved, the load of the driver is effectively reduced, and the purpose of reducing the power consumption is achieved.

As can be seen from fig. 4A and 4B, the polarity of the sub-pixel at the 4 th column in the first area 410 is the same as the polarity of the sub-pixel at the 5 th column in the second area 411, and the polarity of the sub-pixel at the 12 th column in the third area 412 is the same as the polarity of the sub-pixel at the 13 th column in the fourth area 413, so that the first feed-through voltage between the common voltage and the data line voltage in the first area 410 and the second feed-through voltage between the common voltage and the data line voltage in the second area 411 cancel each other, the third feed-through voltage between the common voltage and the data line voltage in the third area 412 and the fourth feed-through voltage between the common voltage and the data line voltage in the fourth area 413 cancel each other, thereby greatly reducing the coupling capacitance traces existing between the data, the electrodes and the thin film transistors of the lcd panel, and solving the luminance non-uniformity, the, The problem of bright and dark lines occurs.

In addition, because the polarity of each sub-pixel (e.g., sub-pixels 421 to 439) is alternately changed between positive and negative in odd frames and even frames, the overall average voltage of each sub-pixel (e.g., sub-pixels 421 to 439) is 0, and the sub-pixels are not biased to a certain polarity, thereby preventing the liquid crystal from being polarized due to long-term rotation in a polar direction, and preventing the problems of losing the rotation capability and forming the residual image due to the burning of the liquid crystal molecules.

Referring to fig. 5A and 5B, fig. 5A and 5B are schematic diagrams of data mapping of the sub-pixels (e.g., sub-pixels 521-539) of the display panel 50 in odd and even frames, respectively, according to an embodiment of the present invention, where a first display luminance of one sub-pixel of adjacent sub-pixels is greater than a second display luminance of another sub-pixel. In the embodiment of the present invention, the first subpixel 521 is set to have higher luminance, the second subpixel 522 adjacent to the first subpixel 521 is set to have lower luminance, the third subpixel 523 adjacent to the second subpixel 522 is set to have higher luminance, the first subpixel 524 adjacent to the third subpixel 523 is set to have lower luminance, and so on in the horizontal direction; in the vertical direction, another first subpixel 537 adjacent to the first subpixel 521 is set to have lower luminance, and another first subpixel 538 adjacent to the first subpixel 537 is set to have higher luminance.

Therefore, in an embodiment of the present invention, the luminance to be displayed is divided into a combination of luminance signals of light and dark, and the combination is respectively transmitted to two adjacent sub-pixels representing the same color, for example: the gray scale value represented by the luminance to be displayed is 100, and by setting the gray scale value of one sub-pixel (e.g., the sub-pixel 521) of two adjacent sub-pixels (e.g., the sub-pixels 521 and 537 or the sub-pixels 521 and 524) representing the same color to 120 and the gray scale value of the other sub-pixel (e.g., the sub-pixel 537 or 524) to 80, the average value of the two sub-pixels is still 100, so that the liquid crystal arrangement in the display panel is richer, the chromaticity viewing angle is larger, and higher resolution is obtained.

Since the sub-pixels of the same type (e.g., the sub-pixels 521, 524, 527, 530, 533, 536, 537 to 539, etc.) are arranged with bright/dark intervals, it is able to avoid the problem that when a specific color is displayed, the sub-pixels representing an undesired color become black spots that are easily seen by the naked eye because they are set to be dark, which may cause the graininess and the moire on the color surface that should be pure.

FIG. 5A and FIG. 5B show the data mapping of the sub-pixel numbers in odd and even frames respectively according to an embodiment of the present disclosure, in an embodiment of the present invention, the sub-pixels (e.g., the sub-pixels 521 to 539, etc.) may receive the luminance signal from the timing controller (see 301 of fig. 3), the luminance arrangement of a plurality of sub-pixels (e.g., sub-pixels 521 to 539 and the like) is switched to a luminance arrangement opposite to the luminance arrangement originally displayed, as shown in fig. 5A and 5B, "H" indicates bright, high brightness or high gray-scale value, "L" indicates dark, low brightness or low gray-scale value, under the control of the brightness control signal, the first display brightness of one of the adjacent sub-pixels in an even frame is larger than the first original brightness in an odd frame, and the second display brightness of the other sub-pixel in the second frame is smaller than the second original brightness in the first frame. For example: two adjacent sub-pixels 521 and 522: in odd frames, subpixel 521 is set to light (H) and subpixel 522 is set to dark (L); in the even frame, the sub-pixel 521 is set to dark (L) and the sub-pixel 522 is set to light (H).
