DETAILED DESCRIPTION OF EMBODIMENTS

The following description, in conjunction with the accompanying drawings of embodiments of the present disclosure, provides a clear and complete description of the technical solutions in the embodiments of the disclosure. It is apparent that the described embodiments are only a part of the embodiments of the disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this disclosure. Furthermore, it should be understood that the specific embodiments described here are only used to explain and illustrate the disclosure and are not intended to limit the disclosure. In this disclosure, unless otherwise specified, directional terms such as “up” and “down” generally refer to the up and down in the actual use or working state of the device, specifically as the direction in the drawings; while “inner” and “outer” refer to the contour of the device.

As shown inFIG.1, compensation states of sub-pixels include a high grayscale data compensation state H and a low grayscale data compensation state L, and the polarities of the sub-pixels include a positive polarity + and a negative polarity −. Taking green, a color to which the human eye is relatively sensitive, as an example, the issues of nodding lines (motion lines) and bright-dark lines are explained. In two adjacent sub-pixel columns of a first area A1, the green sub-pixels G are in a high grayscale data compensation state H and have a negative polarity −. In two adjacent sub-pixel columns of a second area A2, the green sub-pixels G are in a high grayscale data compensation state H and have a positive polarity +. Therefore, the polarity of the green sub-pixels G in the first area A1is completely opposite to the polarity of the green sub-pixels G in the second area A2, resulting in a significant difference in polarity between the two adjacent sub-pixel columns of the first area A1and the second area A2.

Moreover, the green sub-pixels G in the first area A1with the high grayscale data compensation state H and the green sub-pixels G in the second area A2with the high grayscale data compensation state H undergo polarity switching in different frames. When the head is stationary, the brightness in the first area A1and the second area A2is averaged over time and is not easily perceived by the human eye as being uneven. However, once the head moves, this time-averaging effect is disrupted. As a result, the human eye can easily perceive the uneven brightness, leading to the appearance of severe nodding lines.

Furthermore, within each frame duration, average effective voltages transmitted by the first data line DL1, the second data line DL2, and the third data line DL3are all different. For instance, in a frame as shown inFIG.2, the data voltages transmitted to multiple sub-pixels by the first data line DL1are: 0-0-0-0-0-0-0-0-0-0-0-0 . . . ; data voltages transmitted to multiple sub-pixels by the second data line DL2are: 0-(H−)-0-0-0-0-0-(H−)-0-0-0-0 . . . ; data voltages transmitted to multiple sub-pixels by the third data line DL3are: 0-(H+)-0-0-(H+)-0-0-(H+)-0-0-(H+)-0- . . . . Consequently, within a frame, the average effective voltage Vrms_A transmitted by the first data line DL1, the average effective voltage Vrms_B transmitted by the second data line DL2, and the average effective voltage Vrms_C transmitted by the third data line DL3are all different, leading to a distribution of vertical dark lines in the vertical direction (such as the brightness difference between GH− in the first area A1and GH+ in the second area A2), resulting in severe vertical crosstalk issues.

Due to the fact that a light and dark pixel cycle of the angle of view improvement algorithm is consistent with an odd number flip cycle period in the Tri-Gate driving architecture, the polarity pattern of light-dark sub-pixels of different colors in the same column is the same, but the polarity pattern of the sub-pixels in different areas is different. This leads to issues with nodding lines and vertical crosstalk. (For example, considering the green sub-pixels G as shown inFIG.1, by observing the arrangement pattern of the green sub-pixels inFIG.1, it is known that the polarities of the green sub-pixels G with the high grayscale data compensation state H in columns 1, 2, 5, 6, . . . are all “−”; while the polarities of the green sub-pixels G with the high grayscale data compensation state H in columns 3, 4, 7, 8, . . . are all “+”. Such an asymmetric polarity arrangement becomes the cause of nodding lines and vertical crosstalk.)

FIG.3is a schematic plan view of the display device according to one embodiment of the present disclosure. The embodiment provides a display device10. The display device10includes a display panel101and a driving module102.

Optionally, the display panel101includes a liquid crystal display panel.

The display panel101includes multiple sub-pixels SPX, multiple data lines DL, multiple scan lines SL, and a gate driving circuit GDC.

The sub-pixels SPX are used to display images, and these sub-pixels SPX are arranged in a display area DA. The sub-pixels SPX are electrically connected to the data lines DL and the scan lines SL. The sub-pixels SPX are arranged along intersecting row and column directions to form multiple sub-pixel rows SPXR arranged in the column direction, and to also form multiple sub-pixel columns SPXC arranged in the row direction.

Optionally, as shown inFIGS.3to4, the sub-pixel rows SPXR include alternately arranged multiple first sub-pixel rows SPXR1, multiple second sub-pixel rows SPXR2, and multiple third sub-pixel rows SPXR3. The multiple sub-pixels SPX in the same sub-pixel row SPXR exhibit a same display color. The display color of the sub-pixels SPX in the first sub-pixel row SPXR1, the display color of the sub-pixels SPX in the second sub-pixel row SPXR2, and the display color of the sub-pixels SPX in the third sub-pixel row SPXR3are all different from each other.

Optionally, the sub-pixels SPX include multiple first sub-pixels SPX1, multiple second sub-pixels SPX2, and multiple third sub-pixels SPX3. Each of the first sub-pixel rows SPXR1includes multiple first sub-pixels SPX1, each of the second sub-pixel rows SPXR2includes multiple second sub-pixels SPX2, and each of the third sub-pixel rows SPXR3includes multiple third sub-pixels SPX3. That is, the sub-pixels SPX form a Tri-Gate driving architecture.

Optionally, the first sub-pixel SPX1is a blue sub-pixel, the second sub-pixel SPX2is a green sub-pixel, and the third sub-pixel SPX3is a red sub-pixel. Furthermore, the types of the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3are not limited in this regard.

The data lines DL include multiple first data lines DL1and multiple second data lines DL2, with the multiple first data lines DL1and the multiple second data lines DL2being alternately arranged in the row direction. The display panel101includes multiple first sub-pixel groups SPXG1that are electrically connected to the multiple first data lines DL1, and multiple second sub-pixel groups SPXG2that are electrically connected to the multiple second data lines DL2. Each sub-pixel column SPXC includes alternating multiple first sub-pixel groups SPXG1and multiple second sub-pixel groups SPXG2, such that between two adjacent first sub-pixel groups SPXG1connected to the same first data line DL1, there is one second sub-pixel group SPXG2connected to the second data line DL2. Each first sub-pixel group SPXG1is electrically connected to the corresponding first data line DL1, and each second sub-pixel group SPXG2is connected to the corresponding second data line DL2.

Please refer toFIG.3. The gate driving circuit GDC is located within the non-display area NDA. The gate driving circuit GDC drives multiple rows of the sub-pixels SPX via multiple scan lines SL. By sequentially turning on multiple rows of the sub-pixels SPX, data signals are loaded into the multiple rows of the sub-pixels SPX through the data lines DL. This allows the display panel101to display a complete frame within the duration of one frame. The non-display area NDA is located on at least one side of the display area DA. Optionally, the non-display area NDA can at least partially surround the display area DA.

The driving module102includes a circuit board1021and a chip on film (COF)1022. Optionally, the circuit board1021includes a printed circuit board, and the COF1022includes a flexible circuit board. The COF1022includes a source driving chip SIC used to transmit data signals to the multiple data lines DL. The circuit board1021includes a timing control chip TCON. The timing control chip TCON is electrically connected to both the source driving chip SIC and the gate driving circuit GDC. The timing control chip TCON outputs a control timing sequence to the source driving chip SIC and the gate driving circuit GDC, enabling the source driving chip SIC to output the data signals according to the control timing sequence, and the gate driving circuit GDC to drive multiple rows of the sub-pixels SPX according to the control timing sequence.

Continuing with reference toFIG.4, the second sub-pixel group SPXG2includes (2n+1) sub-pixels SPX, where n is greater than or equal to 0, and n is a positive integer. This arrangement allows for a design that implements flipping of pixel polarities at intervals of an odd number of sub-pixels SPX in each pixel column SPXC.

Within the same frame, among the sub-pixels SPX in any pair of adjacent sub-pixel columns SPXC that have the same display color and are in the high grayscale data compensation state H, at least one sub-pixel SPX has a polarity different from the other sub-pixels SPX. This ensures that in any pair of adjacent sub-pixel columns SPXC, the polarities of the sub-pixels SPX with the same display color and in the high grayscale data compensation state H are not uniformly positive (+) or negative (−). This improves the difference in polarity between the sub-pixels SPX with the same display color and in the high grayscale data compensation state H across four adjacent sub-pixel columns SPXC. Consequently, it improves the issue of nodding lines caused by the perception of brightness changes due to significant polarity differences in the regions where head movement occurs and polarities change.

Taking n=1 as an example, the pixel polarity flipping design for the sub-pixels SPX in each sub-pixel column SPXC is explained.

Continuing with reference toFIG.4, within the same frame, the polarities of the sub-pixels SPX in the first sub-pixel groups SPXG1are the same, and the polarities of the sub-pixels SPX in the second sub-pixel groups SPXG2are also the same. However, the polarities of the sub-pixels SPX in the first sub-pixel groups SPXG1are opposite to the polarities of the sub-pixels SPX in the second sub-pixel groups SPXG2. This ensures that the polarities of the sub-pixels SPX in the first sub-pixel groups SPXG1connected to the same first data line DL1are the same, and the polarities of the sub-pixels SPX in the second sub-pixel groups SPXG2connected to the same second data line DL2are the same. Further, the polarities of the sub-pixels SPX in the first sub-pixel groups SPXG1connected to the first data line DL1are opposite to the polarities of the sub-pixels SPX in the second sub-pixel groups SPXG2connected to the adjacent second data line DL2.

This allows for a design that achieves pixel polarity flipping at intervals of three sub-pixels SPX in each pixel column SPXC. For example, in each pixel column SPXC, between two adjacent first sub-pixel groups SPXG1, there is a second sub-pixel group SPXG2that includes three sub-pixels SPX. Within the same frame, the polarities of the sub-pixels SPX in the first sub-pixel groups SPXG1are either positive or negative, and the polarities of the sub-pixels SPX in the second sub-pixel groups SPXG2are the opposite. Therefore, in each pixel column SPXC, flipping between positive and negative polarity, or vice versa, can be achieved with an interval of three sub-pixels SPX.

Optionally, within the same sub-pixel column SPXC, where multiple sub-pixels SPX have the same display color and are in the high grayscale data compensation state H, the polarities of two adjacent sub-pixels SPX are opposite. For example, in the first sub-pixel column SPXC1, among the second sub-pixels SPX2with the high grayscale data compensation state H, the polarities of these second sub-pixels SPX2alternate between negative (−) and positive (+). This arrangement in the sub-pixel column SPXC ensures that the polarities of the sub-pixels SPX with the same display color and in the high grayscale data compensation state H are not uniformly positive (+) or negative (−). This improves the difference in polarity between the sub-pixels SPX with the same display color and in the high grayscale data compensation state H in two adjacent sub-pixel columns SPXC. Consequently, this can ameliorate the phenomenon of nodding lines observed by the human eye due to significant polarity differences in the regions when head movement occurs.

Optionally, within a single frame in the sub-pixel column SPXC, positions of the first sub-pixels SPX1with negative polarity − are at SPX1H−=12 (y1-1)+7, and positions of the first sub-pixels SPX1with positive polarity + are at SPX1H+=12 (y1-1)+10; positions of the second sub-pixels SPX2with negative polarity − are at SPX2H−=12 (y1-1)+2, and positions of the second sub-pixels SPX2with positive polarity + are at SPX2H+=12 (y1-1)+11; positions of the third sub-pixels SPX3with negative polarity − are at SPX3H−=12 (y1-1)+3, and positions of the third sub-pixels SPX3with positive polarity + are at SPX3H+=12 (y1-1)+6. Here, y1 is greater than or equal to 1. That is, within a single frame in the sub-pixel column SPXC, the sub-pixel rows SPXR corresponding to the first sub-pixels SPX1with negative polarity − are: 7, 19, 31, . . . , and the sub-pixel rows SPX corresponding to the first sub-pixels SPX1with positive polarity + are: 10, 22, 34, . . . ; the sub-pixel rows SPXR corresponding to the second sub-pixels SPX2with negative polarity − are: 2, 14, 26, . . . , and the sub-pixel rows SPXR corresponding to the second sub-pixels SPX2with positive polarity + are: 11, 23, 35, . . . ; the sub-pixel rows SPXR corresponding to the third sub-pixels SPX3with negative polarity − are: 3, 15, 27, . . . , and the sub-pixel rows SPXR corresponding to the third sub-pixels SPX3with positive polarity + are: 6, 18, 30, . . . . Therefore, in the design of flipping pixel polarities at intervals of three sub-pixels SPX in the sub-pixel column SPXC, if the sub-pixel row SPXR divided by 6 has a remainder of 1, then the sub-pixel row SPXR corresponds to the position where the first sub-pixel SPX1has the negative polarity −. If the sub-pixel row SPXR divided by 6 has a remainder of 4, the sub-pixel row SPXR corresponds to the position where the first sub-pixel SPX1has the positive polarity +. If the sub-pixel row SPXR divided by 6 has a remainder of 2, the sub-pixel row SPXR corresponds to the position where the second sub-pixel SPX2has the negative polarity −. If the sub-pixel row SPXR divided by 6 has a remainder of 5, the sub-pixel row SPXR corresponds to the position where the second sub-pixel SPX2has the positive polarity +. If the sub-pixel row SPXR divided by 6 has a remainder of 3, the sub-pixel row SPXR corresponds to the position where the third sub-pixel SPX3has the negative polarity −. If the sub-pixel row SPXR divided by 6 has a remainder of 0, the sub-pixel row SPXR corresponds to the position where the third sub-pixel SPX3has the positive polarity +. This ensures that the distribution of the sub-pixels SPX in the high grayscale data compensation state H in the sub-pixel column SPXC is evenly staggered, thereby reducing the chance of nodding lines issues. It is understandable that in the adjacent frame, the polarities of the sub-pixels SPX are swapped between positive and negative.

As shown inFIG.5, within the same frame, when the sub-pixels SPX with the same display color and in the high grayscale data compensation state H display the same grayscale level, the absolute values of the average effective voltages of adjacent first data line DL1and second data line DL2are the same. For example, when lighting up the second sub-pixels SPX2with the high grayscale data compensation state H in the same frame, the voltage of the first data line DL1can be represented as: 0-0-0-0-(H−)-0-0-(H−)-0-0-0-0 . . . , and the voltage of the second data line DL2can be represented as: 0-(H+)-0-0-0-0-0-(H+)-0-0-0-0 . . . . Therefore, the average effective voltages of the first data line DL1and the second data line are identical in magnitude but opposite in polarity during the same frame. This can effectively reduce the risk of vertical crosstalk phenomena.

Optionally, continuing with reference toFIG.4, within the same sub-pixel row SPXR, the grayscale data compensation states of two adjacent sub-pixels SPX repeat in an alternating sequence of opposite and same. For example, in the first six sub-pixels SPX of the first sub-pixel row SPXR1, the grayscale data compensation states of the six sub-pixels SPX are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H.

Alternatively, continuing with reference toFIGS.6and7, in the first six sub-pixels SPX of the first sub-pixel row SPXR, the grayscale data compensation states of the six sub-pixels SPX are in the order of high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L.

Continuing with reference toFIG.4, within the same sub-pixel column SPXC, the grayscale data compensation states of two adjacent sub-pixels SPX repeat in an alternating sequence of opposite and same. For example, in the first sub-pixel column SPXC1, the grayscale data compensation states of multiple sub-pixels SPX are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L.

Referring toFIG.6, this embodiment is similar to the first embodiment, with the difference being: within the same sub-pixel column SPXC, the grayscale data compensation states of the sub-pixels SPX follow a repeating sequence of high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, and high grayscale data compensation state H. This arrangement ensures that the distribution of the sub-pixels SPX in the high grayscale data compensation state H within the sub-pixel column SPXC is evenly staggered, thereby reducing the risk of nodding lines issues.

Specifically, this is explained using an example where both the first sub-pixel group SPXG1and the second sub-pixel group SPXG2include the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3arranged in the column direction.

In the same sub-pixel column, the grayscale data compensation states of the first sub-pixels SPX1in the first sub-pixel groups SPXG1repeat in an alternating sequence of opposite and same. Similarly, the grayscale data compensation states of the second sub-pixels SPX2in the first sub-pixel groups SPXG1also repeat in an alternating opposite and same sequence. In the same sub-pixel column, the grayscale data compensation states of the third sub-pixels SPX3in the first sub-pixel groups SPXG1repeat in an alternating sequence of same and opposite. The grayscale data compensation state of the first sub-pixel SPX1in the second sub-pixel group SPXG2is opposite to the grayscale data compensation state of the third sub-pixel SPX3in the immediately preceding adjacent first sub-pixel group SPXG1. The grayscale data compensation states of the second sub-pixels SPX2in the second sub-pixel groups SPXG2repeat in an alternating sequence of same and opposite, and the grayscale data compensation states of the third sub-pixels SPX3in the second sub-pixel groups SPXG2repeat in an alternating sequence of opposite and same. Here, the grayscale data compensation state of the third sub-pixel SPX3in each second sub-pixel group SPXG2is the same as the grayscale data compensation state of the first sub-pixel SPX1in the immediately preceding adjacent first sub-pixel group SPXG1.

For example, in the first sub-pixel column SPXC1, the grayscale data compensation states of the first sub-pixels SPX1in the first sub-pixel groups SPXG1are in the order of high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, and so on. In the first sub-pixel column SPXC1, the grayscale data compensation states of the second sub-pixels SPX2in the first sub-pixel groups SPXG1are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, and so on. In the first sub-pixel column SPXC1, the grayscale data compensation states of the third sub-pixels SPX3in the first sub-pixel groups SPXG1are in the order of high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, and so on. In the first sub-pixel column SPXC1, the grayscale data compensation states of the first sub-pixels SPX1in the second sub-pixel groups SPXG2are in the order of low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, and so on. In the first sub-pixel column SPXC1, the grayscale data compensation states of the second sub-pixels SPX2in the second sub-pixel groups SPXG2are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, and so on. In the first sub-pixel column SPXC1, the grayscale data compensation states of the third sub-pixels SPX3in the second sub-pixel groups SPXG2are in the order of high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, and so on.

Similarly, within the same sub-pixel column SPXC, the grayscale data compensation states of the sub-pixels SPX repeat in a sequence of low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L. This pattern ensures that the distribution of the sub-pixels SPX in the high grayscale data compensation state H within the sub-pixel column SPXC is evenly staggered, thereby reducing the risk of nodding lines issues.

For example, in the second sub-pixel column SPXC2, the grayscale data compensation states of the first sub-pixels SPX1in the first sub-pixel groups SPXG1are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the second sub-pixels SPX2in the first sub-pixel groups SPXG1are in the order of high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the third sub-pixels SPX3in the first sub-pixel groups SPXG1are in the order of low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the first sub-pixels SPX1in the second sub-pixel groups SPXG2are in the order of high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the second sub-pixels SPX2in the second sub-pixel groups SPXG2are in the order of high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the third sub-pixels SPX3in the second sub-pixel groups SPXG2are in the order of low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, and so on.

Referring toFIG.7, in this embodiment, within the same sub-pixel column SPXC, the grayscale data compensation states of the sub-pixels SPX repeat in a sequence of high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H. This pattern ensures that the distribution of the sub-pixels SPX in the high grayscale data compensation state H within the sub-pixel column SPXC is evenly staggered, thereby reducing the risk of nodding lines issues.

Correspondingly, within the same sub-pixel column, the grayscale data compensation state of the sub-pixel SPX adjacent to the second sub-pixel SPX2in the first sub-pixel group SPXG1is opposite to the grayscale data compensation state of the sub-pixel SPX adjacent to the first sub-pixel SPX1in the second sub-pixel group SPXG2. The grayscale data compensation states of the sub-pixels SPX with the same display color in the first sub-pixel groups SPXG1repeat in the opposite order, and the grayscale data compensation states of the sub-pixels SPX with the same display color in the second sub-pixel groups SPXG2also repeat in the opposite order. In each first sub-pixel group SPXG1, the grayscale data compensation states of two adjacent sub-pixels SPX are opposite, and in each second sub-pixel group SPXG2, the grayscale data compensation states of two adjacent sub-pixels SPX are opposite.

As an example, still considering the first sub-pixel group SPXG1and the second sub-pixel group SPXG2which both include the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3arranged along the column direction. In the first sub-pixel column SPXC1, the grayscale data compensation states of the first sub-pixels SPX1in the first sub-pixel groups SPXG1are in the order of high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, and so on.

Similarly, within the same sub-pixel column SPXC, the grayscale data compensation states of the sub-pixels SPX repeat in a sequence of low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L. This pattern ensures that the distribution of the sub-pixels SPX in the high grayscale data compensation state H within the sub-pixel column SPXC is evenly staggered, thereby reducing the chance of nodding lines issues.

For example, in the second sub-pixel column SPXC2, the grayscale data compensation states of the first sub-pixels SPX1in the first sub-pixel groups SPXG1are in the order of low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, and so on. In the second sub-pixel column SPXC2, the grayscale data compensation states of the second sub-pixels SPX2in the first sub-pixel groups SPXG1are in the order of high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, high grayscale data compensation state H, low grayscale data compensation state L, and so on.

Referring toFIG.8, one embodiment of the present disclosure also provides a driving method for a display panel, applied in the aforementioned display module1, to drive the display panel101. The driving method can be implemented by the source driving chip SIC executing corresponding program instructions. The driving method includes:

S1: driving multiple sub-pixels SPX for display across multiple frames.

Wherein, each sub-pixel SPX, within these multiple frames, has a high grayscale data compensation state H and a low grayscale data compensation state L, and possesses either a positive polarity + or a negative polarity −.

Each sub-pixel column SPXC includes multiple sub-pixel groups SPXG. The sub-pixel groups SPXG include a plurality of first sub-pixel groups SPXG1which are electrically connected to the first data line DL1, and a plurality of second sub-pixel groups SPXG2which are electrically connected to the second data line DL2. The first sub-pixel groups SPXG1and the second sub-pixels SPX2are alternately arranged in the column direction. The second sub-pixel group SPXG2includes (2n+1) sub-pixels SPX, where n is a positive integer, to achieve a design that flips pixel polarities at intervals of an odd number of the sub-pixels SPX in each pixel column.

Optionally, within the same frame, among the sub-pixels SPX in any pair of adjacent sub-pixel columns SPXC that have the same display color and are in the high grayscale data compensation state H, at least one sub-pixel SPX has a polarity different from the other sub-pixels SPX. This ensures that in any pair of adjacent sub-pixel columns SPXC, the polarities of the sub-pixels SPX with the same display color and in the high grayscale data compensation state H are not uniformly positive (+) or negative (−). This improves the difference in polarity between the sub-pixels SPX with the same display color and in the high grayscale data compensation state H across four adjacent sub-pixel columns SPXC. Consequently, this can alleviate the phenomenon of nodding lines observed by the human eye due to significant polarity differences in the regions when head movement occurs.

Furthermore, every p frames, the polarities of the sub-pixels SPX in the sub-pixel groups PXG are reversed to achieve polarity symmetry over time. Here, p is a positive integer and is greater than or equal to 1.

One embodiment of the present disclosure also provides a driving chip. The driving chip includes a timing control chip and a source driving chip connected to the timing control chip. The driving chip is configured to execute program instructions to implement the aforementioned driving method.
