Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display panel and its driving method, and a display device. Background Technology

[0002] Dual-gate technology is a driving technique that reduces the number of data lines in a display device by half and doubles the number of gate lines. Compared to conventional display devices with multiple source driver ICs and multiple gate driver ICs, dual-gate technology halves the number of source driver ICs connected to the data lines and doubles the number of gate driver ICs connected to the gate lines. Since the unit price of gate driver ICs is lower than that of source driver ICs, this results in a cost reduction. Summary of the Invention

[0035] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0036] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0038] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. For example, the term "connected" may be used in describing some embodiments to indicate that two or more components have direct physical or electrical contact with each other. Similarly, the term "coupled" may be used in describing some embodiments to indicate that two or more components have direct physical or electrical contact. However, the terms "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0039] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0040] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0041] As used herein, depending on the context, the term “if” may optionally be interpreted as meaning “when”, “in the event of”, “in response to determination”, or “in response to detection”. Similarly, depending on the context, the phrase “if it is determined that…” or “if [the stated condition or event] is detected” may optionally be interpreted as meaning “in the event of determination that…”, “in response to determination that…”, “when [the stated condition or event] is detected”, or “in response to the detection of [the stated condition or event]”.

[0042] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0043] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0044] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and regions is enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched regions shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0045] In display devices, Liquid Crystal Displays (LCDs) dominate the current display device market due to their small size, low power consumption, relatively low manufacturing cost, and lack of radiation. To prevent the liquid crystal molecules from solidifying during image display, alternating current (AC) is typically used for driving. Specifically, the data signal of an LCD changes polarity based on a common voltage. When the data signal voltage is greater than the common voltage, the driving signal is positive; otherwise, it is negative. If a positive data signal is applied to a sub-pixel, that sub-pixel becomes positive; if a negative data signal is applied to a sub-pixel, that sub-pixel becomes negative. Currently, common driving methods for LCDs include row inversion, column inversion, and dot inversion. When an LCD uses column inversion, the polarity of the data signal is reversed every predetermined number of sub-pixel columns during the display of one frame of an image.

[0046] For example, in a liquid crystal display using dual-gate technology, adjacent columns of sub-pixels can share a single data line. With the column inversion method, during the display of a frame, the polarity of the data signal on each data line is always the same (positive or negative), while the polarities of adjacent data lines are opposite. Thus, within a frame, multiple sub-pixel columns arranged along the row direction are filled with data signals of positive-positive-negative-negative polarities in a cyclical pattern. Consequently, there is a π (180°) phase difference between the flicker waveforms of sub-pixel columns coupled to adjacent data lines, which helps suppress flicker to some extent. However, within the same frame, two sub-pixel columns coupled to each data line are filled with data signals of the same polarity, and their flicker waveforms have no phase difference, easily causing line flicker in the column direction. Therefore, in the next frame, the polarity of the data signal on each data line needs to be changed to suppress flicker.

[0047] If the user is constantly viewing the display, the polarity of the same sub-pixel column is reversed in adjacent frames, thus suppressing line flicker in the column direction. However, when the user shakes their head, frames of the observed image may be lost, which may result in the flicker in the column direction of one frame not being suppressed in the next frame. This can easily lead to display defects such as V-line, which means that when the user shakes their head, they will see periodic alternating bright and dark vertical stripes on the screen.

[0048] To address this problem, some embodiments of this disclosure provide a display device. Exemplarily, the display device may be: a monitor, television, billboard, digital photo frame, laser printer with display function, telephone, mobile phone, personal digital assistant (PDA), digital camera, portable camcorder, viewfinder, navigator, automotive display device, video wall display device, home appliance, information query device (such as business query device for e-government, banking, hospitals, power, etc.), monitor, etc.

[0049] In some embodiments of this disclosure, see Figure 1 The display device includes a display panel 100. The display panel can be a liquid crystal display panel, for example, an AD-SDS (Advanced-Super Dimensional Switching) type liquid crystal display panel, which has advantages such as high transmittance, wide viewing angle, high aperture ratio, low color difference, low response time, and no push mura, further improving picture quality, broadening the application range, and having a wider application prospect. The display device may also include a backlight module 2, configured to provide backlight to the display panel 1.

[0050] Exemplarily, the display device may also include a driver chip. For example, the driver chip is a driver IC, which includes a source driver. Specifically, the driver chip is configured to provide data signals to the display panel 100. See also... Figure 1 The display panel 100 may include an array substrate 101 and a cell substrate 102, as well as a liquid crystal layer 103 disposed between the array substrate 101 and the cell substrate 102. To achieve color display, the display panel 100 may also include a color filter layer. This color filter layer may be disposed on the cell substrate 102, in which case the cell substrate 102 with the color filter layer can be referred to as a color filter substrate.

[0051] See Figure 2 The display panel has a display area (active area, abbreviated as AA) and a peripheral area S. The peripheral area S is located on at least one side of the display area. For example, the peripheral area S can be arranged around the display area.

[0052] In some embodiments of this disclosure, the display panel 100 may include a plurality of sub-pixels P, which are located in area AA and arranged in an array along both row and column directions. For example, sub-pixels P arranged in a row are called pixels in the same row, and sub-pixels P arranged in a column are called pixels in the same column. The row direction is represented by X, and the column direction by Y.

[0053] For example, each row of subpixels includes multiple first-color subpixels, multiple second-color subpixels, and multiple third-color subpixels. For example, the first, second, and third colors are not limited and can be any of the three primary colors or other colors. For instance, the first, second, and third colors are blue, green, and red, respectively; that is, the multiple subpixels P include blue subpixels, green subpixels, and red subpixels.

[0054] There are no restrictions on the arrangement of subpixels P in each row, nor on the arrangement of adjacent rows of subpixels P. For example, a subpixel group 240 can be formed by an adjacent first-color subpixel, a second-color subpixel, and a third-color subpixel arranged in any order. Each row of subpixels P may include multiple repeated subpixel groups 240. The arrangement of adjacent rows of subpixels P can be the same or different. For example, Figure 2 In this diagram, the first color subpixel is red (R), the second color subpixel is green (G), and the third color subpixel is blue (B). Each row of subpixels P includes multiple repeating subpixel groups 240. In odd-numbered rows, each subpixel group 240 includes one red subpixel R, one green subpixel G, and one blue subpixel B arranged in sequence; in even-numbered rows, each subpixel group 240 includes one blue subpixel B, one red subpixel R, and one green subpixel G arranged in sequence. Alternatively, the arrangement of subpixels P may be identical across all rows.

[0055] Each sub-pixel P may include a pixel electrode 250 and a common electrode 260. The electric field formed between the two electrodes is applied to the liquid crystal molecules in the sub-pixel P, causing the liquid crystal molecules in the sub-pixel P to align in a corresponding manner, thereby controlling the light emission brightness of the sub-pixel P. Furthermore, each sub-pixel P also includes a switching device coupled to the pixel electrode 250. For example, the switching device may be a thin-film transistor.

[0056] The pixel electrode 250 and the common electrode 260 can be disposed on the same side of the liquid crystal layer. For example, in an AD-SDS type display panel, the array substrate includes pixel electrodes and a common electrode, one of which typically has a slit. The vertical positions of the common electrode and the pixel electrode can be varied. The orientation angle of the slit can be set as needed; for example, to achieve a high aperture ratio, the slit can be set parallel to the data line. Of course, the pixel electrode 250 and the common electrode 260 can also be disposed on opposite sides of the liquid crystal layer. The display panel 100 (e.g., an array substrate) also includes multiple gate lines GL and multiple data lines DL. The gate lines GL can be used to transmit gate drive signals (also called scan signals) to sequentially activate multiple sub-pixels P in the display panel 100; the data lines DL are configured to provide data signals to the activated sub-pixels P. For example, in each sub-pixel P, the gate of the thin-film transistor is coupled to a gate line, the first electrode (e.g., the source) is coupled to a data line, and the second electrode (e.g., the drain) is coupled to the pixel electrode. Thus, the on or off state of the thin-film transistor determines whether the data line can supply data signals to the pixel electrode. Exemplarily, the display panel 100 may also include a GOA (Gatedriver On Array) circuit connected to the gate line GL for providing a gate drive signal to the gate line GL. The GOA circuit includes multiple GOA units, each coupled to a corresponding gate line GL.

[0057] See below. Figures 4 to 10 This disclosure provides structural diagrams of array substrates in various display panels. The patterns containing R, G, and B represent pixel electrodes in the red, green, and blue sub-pixels of the display panel, respectively.

[0058] See Figure 4 The multiple gate lines include alternating first gate lines GL1 and second gate lines GL2 arranged in the column direction, and adjacent first gate lines GL1 and second gate lines GL2 form a gate line pair 220. Two gate lines in the same gate line pair 220 are coupled to sub-pixels P in the same row. Exemplarily, the two gate lines GL in the same gate line pair 220 can be located on opposite sides of the coupled sub-pixels P in the column direction, i.e., a row of sub-pixels P is located between the two gate lines GL in the coupled gate line pair 220. Also exemplaryly, the two gate lines in the same gate line pair 220 can be located on the same side of the coupled sub-pixels P in the column direction. See also, for an example... Figure 4 In the same row of sub-pixels P, each first-color sub-pixel is coupled to a first gate line GL1. This allows the first-color sub-pixels located in the same row to be enabled by a single first gate line GL1. Figure 3The diagram illustrates the case where subpixels of the same color located in the same row are activated by different gate lines. GL1 inputs gate drive signals to multiple subpixels P coupled to it in the same row to activate subpixels P. Subpixels P receive data signals transmitted via data line DL and display the corresponding color under the drive of the data signals. Taking the first color subpixel as a red subpixel as an example, see [link to example]. Figure 3 In (a) of the diagram, multiple red sub-pixels coupled to GL1 in the same row are first enabled and their display colors are updated under the drive of the data signal. See also... Figure 3 In (b), multiple red sub-pixels coupled to GL2 are activated and updated in display color under the drive of data signals. There is a time difference in the display color update of multiple red sub-pixels in the same row, which causes the same color sub-pixels in the same row to display different colors at the same time, which has an adverse effect on the display effect.

[0059] In the embodiments of this disclosure, each first color sub-pixel in the same row of sub-pixels P is coupled to a first gate line GL1. This allows the first color sub-pixels located in the same row to be simultaneously activated by a first gate line GL1 and to update their display color simultaneously under the drive of the data signal, thereby avoiding the display flickering problem of a certain color in the same row and achieving a better display effect.

[0060] For example, see Figure 3 Taking red as the first color sub-pixel as an example, some red sub-pixels in the same row are activated by GL1, while the remaining red sub-pixels in the same row are activated by GL2. Because there is a time difference between the gate drive signals transmitted by GL1 and GL2 that activate sub-pixels in the same row during actual driving, red sub-pixels in the same row cannot be activated simultaneously, resulting in display flickering in the row direction and negatively impacting the display effect. However, by having the first color sub-pixels in the same row activated by a single first gate line GL1, it is ensured that the first color sub-pixels in the same row are activated simultaneously, thus avoiding the aforementioned problem and achieving a better display effect.

[0061] For example, in the same row of sub-pixels P, each second-color sub-pixel is coupled to a second gate line GL2. The function of this connection setting is similar to that of the first-color sub-pixel connection setting described above, and will not be repeated here.

[0062] Multiple data lines DL include a first data line DL1 and a second data line DL2 that are alternately arranged in the row direction. The first data line DL1 and the second data line DL2 are configured to transmit data signals with different polarities.

[0063] In the same row of sub-pixels P, two adjacent sub-pixels P form a sub-pixel pair 230. The two sub-pixels P in the same sub-pixel pair 230 are coupled to the same data line DL. Each pair of adjacent sub-pixel pairs 230 is coupled to a first data line DL1 and a second data line DL2, respectively. Different sub-pixels P coupled to the same data line DL are coupled to different gate lines GL. For example, the relative position of the sub-pixel pair 230 and the data line DL is not limited, as long as the above connection relationship can be achieved. For example, two adjacent sub-pixel pairs 230 can be located between a first data line DL1 and a second data line DL2 coupled to them in the row direction. Or, the positions of two adjacent sub-pixel pairs 230 and the first data line DL1 and the second data line DL2 coupled to them in the row direction are distributed as follows: sub-pixel pair 230, first data line DL1, second data line DL2, and sub-pixel pair 230.

[0064] With the first color sub-pixel being red (R), the second color sub-pixel being green (G), and the third color sub-pixel being blue (B), in the same row of sub-pixels P, each first color sub-pixel P1 is coupled to a first gate line GL1, and each second color sub-pixel P2 is coupled to a second gate line GL2. Simultaneously, different sub-pixels P coupled to the same data line DL are coupled to different gate lines GL. That is, in the same row of sub-pixels P, each red sub-pixel R is coupled to a first gate line GL1, each green sub-pixel G is coupled to a second gate line GL2, and each blue sub-pixel B is alternately coupled to the first gate line GL1 and the second gate line GL2. Since the blue sub-pixel B has the lowest luminous intensity compared to the red and green sub-pixels R and G, it has the least impact on the uniformity of luminous intensity. Therefore, this configuration can minimize the impact of different color sub-pixels P on the uniformity of luminous intensity of the display panel 100.

[0065] Multiple sub-pixels P of the same color located in the same column include: alternating first-type sub-pixels and second-type sub-pixels, each first-type sub-pixel coupled to a first data line DL1, and each second-type sub-pixel coupled to a second data line DL2. That is, in the display panel 100, at least one (e.g., multiple) data lines DL are not signal lines extending in a straight line in the column direction, but rather have bends. For example, multiple first data lines DL1 and multiple second data lines DL2 are not signal lines extending in a straight line in the column direction, but rather have bends, such that some of the multiple sub-pixels P of the same color in the same column are coupled to the first data line DL1, and the rest are coupled to the second data line DL2. Since the data signal polarities transmitted by the first data line DL1 and the second data line DL2 are different, the polarities of the multiple sub-pixels P of the same color coupled to them in the same column are also different. Specifically, alternating distribution refers to the simultaneous presence of positive and negative polarities in sub-pixels P of the same color and located in the same column. During the display of one frame of an image, some (at least one) positive polarity sub-pixels P and some (at least one) negative polarity sub-pixels P are alternately distributed. This alternating distribution can be periodically repeated or an arbitrary mixture; there are no restrictions on this. For example, for red sub-pixels, alternating distribution means that during the display of one frame of an image, see [see...] Figure 4 In the column direction, the polarity of red sub-pixels located in the same column repeats periodically in the order of positive, negative, and negative; for example, see... Figure 6 The polarity of red sub-pixels located in the same column along the column direction is positive and negative, repeating periodically.

[0066] For the same sub-pixel P, its brightness varies when the polarity of the input data signal is different. The above setting method uses a column-reversed data signal input method to achieve a display effect similar to dot reversal. During the display of each frame of the image, the polarity of multiple sub-pixels P with the same color in the same row can cycle in a positive-positive-negative-negative pattern, and the polarity of multiple sub-pixels P with the same color in the same column can be mixed with positive and negative polarities. Therefore, for each sub-pixel P in the AA area, the brightness can be averaged in both the row and column directions in each frame, achieving a better display effect. Thus, when the polarity of the same sub-pixel P is reversed in two adjacent frames, the display flickering problem caused by local sub-pixels of the same color having the same polarity will not occur.

[0067] For example, a data line DL coupled to a pixel pair 230 is located between two sub-pixels P in the pixel pair 230. See, for example, [link to documentation]. Figure 4The positions of two adjacent sub-pixel pairs 230 and their respective coupled first data line DL1 and second data line DL2 in the row direction are distributed as follows: sub-pixel pair 230, first data line DL1, sub-pixel pair 230, and second data line DL2. In this way, the data line DL can be coupled to two sub-pixels P in a pixel pair 230 without needing to be wound, simplifying the wiring scheme and helping to control production costs.

[0068] For example, two sub-pixel pairs 230 located in adjacent rows of sub-pixels P and coupled to the same data line DL, wherein the two sub-pixels P in one sub-pixel pair 230 are located in column j and column j+1 respectively, and the two sub-pixels P in the other sub-pixel pair 230 are located in column j-1 and column j respectively; wherein column j-1, column j, and column j+1 are three consecutive columns. Here, j is a positive integer. That is, the shape of the data line DL within at least two rows (e.g., multiple rows) is such that for each row extended downwards in the column direction, it extends left or right across one sub-pixel P in the row direction. For example, see... Figures 4-7 Within the first to fourth rows of the display panel 100, the data line DL extends downwards along the column direction, then crosses one sub-pixel P to the left along the row direction, repeating the above routing method. In this way, only three signal lines exist between adjacent sub-pixels P in the same column: one first gate line GL1, one second gate line GL2, and one data line DL. The distance between adjacent sub-pixels P is small, which helps to increase the pixel density per unit area and achieve a higher display resolution.

[0069] For example, one of the multiple data lines DL includes: multiple data sub-lines DL' connected sequentially, each data sub-line DL' being coupled to Q sub-pixel pairs 230 located in different rows, and the i-th sub-pixel pair 230 coupled to each data sub-line DL' being located in the same two columns; where i∈[1,Q], and Q≥2. For example, see Figure 10 When Q = 4, each data sub-line DL' is coupled to four sub-pixel pairs 230 located in different rows. That is, the extension range of each data sub-line DL' is four rows, and the sub-pixel pair 230 located in the i-th row within the extension range of each data sub-line DL' is the i-th sub-pixel pair 230 coupled to the data sub-line DL', where i = 1, 2, 3, 4. Figure 10 As can be seen, the second sub-pixel pair 230 and the fourth sub-pixel pair 230 are located in the same two columns. See also... Figure 6 When Q=8, the 2nd sub-pixel pair 230 and the 8th sub-pixel pair 230 are located in the same two columns, the 3rd sub-pixel pair 230 and the 7th sub-pixel pair 230 are located in the same two columns, and the 4th sub-pixel pair 230 and the 6th sub-pixel pair 230 are located in the same two columns.

[0070] For example, Q is an even number, and Q ≥ 4. In this case, among the Q sub-pixel pairs 230 coupled to each data sub-line DL', the k-th sub-pixel pair 230 and the Q-k+2-th sub-pixel pair 230 are located in the same two columns; where k ∈ [2, Q / 2]. For example, Q = 6. When Q = 6, k ∈ [2, 3]. See specifically. Figures 4-5 , Figure 7 When k=2, the second sub-pixel pair 230 and the sixth sub-pixel pair 230 are located in the same two columns; when k=3, the third sub-pixel pair 230 and the fifth sub-pixel pair 230 are located in the same two columns. When Q=6, the winding distance of each data line DL in the display panel 100 is relatively short, thus making the brightness of the sub-pixels P of the same color in each row moderate, achieving a good display effect.

[0071] For example, within the same column of sub-pixels P, every two adjacent sub-pixels P have different colors; that is, the arrangement of sub-pixels P in adjacent rows is not the same. For example, multiple sub-pixels P in the same column can be arranged periodically, with the period being 2 rows, 3 rows, 4 rows, or other periods, without limitation. Specifically, when the period is 2 rows, in each odd-numbered row of sub-pixels P, the sub-pixels P located in the same column have the same color; in each even-numbered row of sub-pixels P, the sub-pixels P located in the same column have the same color. For example, see... Figures 4 to 10 A subpixel group 240 includes a red subpixel R, a green subpixel G, and a blue subpixel B arranged in sequence. Each row of subpixels P includes multiple repeated subpixel groups 240. At the same time, the arrangement period of multiple subpixels P in the same column is 2 rows. Taking the first column as an example, the two subpixels P in the odd-numbered rows in the first column have the same color, the two subpixels P in the even-numbered rows have the same color, and the two subpixels P in any two adjacent rows have different colors.

[0072] For example, see Figure 4 With Q=6, the shape setting of the data sub-line DL' and the setting method of the sub-pixel group 240 as described above, and the arrangement period of multiple sub-pixels P being 2 rows, multiple sub-pixels P with the same color but different polarities in the same row and column are mixed evenly. There is no situation where the polarity of the entire column of sub-pixels P of the same color is the same, which can achieve average brightness and achieve a better display effect.

[0073] Specifically, there are no major restrictions on the shape of the data sub-lines DL' and their distribution range in the display panel 100. Multiple parallel data sub-lines DL' can be set throughout the entire AA area, or multiple parallel data sub-lines DL' can be set only in a localized area of ​​the AA area. In other locations within the AA area, the data lines DL are still set in a conventional linear extension configuration. For example, the shape of the data sub-lines DL' can be as follows: Figures 4-5 , Figure 7 As shown, Q = 6. In rows 1 to 3, each row extending downwards in the column direction crosses one sub-pixel P to the left (or right). In rows 4 to 6, each row extending downwards in the column direction crosses one sub-pixel P to the right (or left). For example, the shape of the data sub-line DL' can be as follows: Figure 6 As shown, Q = 8. In rows 1 to 4, each row extending downwards in the column direction crosses one sub-pixel P to the left (or right). In rows 5 to 8, each row extending downwards in the column direction crosses one sub-pixel P to the right (or left). For example, the shape of the data sub-line DL' can be as follows... Figure 8 As shown, Q=4. In row 1, it extends two rows downwards, crossing two sub-pixels P to the left (or right) in the column direction. In rows 3 and 4, it extends one row downwards, crossing two sub-pixels P to the right (or left). For example, the shape of the data sub-line DL' can be as follows: Figure 9 As shown, Q=4. In rows 1 and 2, extending downwards in the column direction by one sub-pixel P to the right (or left). In row 3, extending downwards in the column direction by three sub-pixels P to the left (or right). In row 4, extending downwards in the column direction by three sub-pixels P to the right (or left). For example, the shape of the data sub-line DL' can be as follows... Figure 10 As shown, Q=4. In rows 1 and 2, each time the column extends downwards, it crosses one sub-pixel P to the left (or right). In rows 3 and 4, each time the column extends downwards, it crosses one sub-pixel P to the right (or left). The beneficial effects achieved by the above-described various data sub-line DL' settings are consistent with the beneficial effects of the aforementioned embodiments, and will not be repeated here.

[0074] For example, multiple data lines DL are arranged in parallel. The shapes, i.e., the wiring methods, of the multiple data lines DL in the display panel 100 are consistent. The above arrangement can make the length of each data line DL in the display panel 100 consistent, and the resistance value input to each row of sub-pixels P is equal, thereby making the light emission brightness of sub-pixels P of the same color in each row consistent, resulting in better display effect.

[0075] The display panel 100 can also have touch functionality. Commonly used touch technologies include on-cell touch technology and in-cell touch technology. In particular, in-cell touch technology can be used to implement touch functionality on the display panel 100.

[0076] For example, the display panel 100 also includes multiple touch signal lines TL, at least one of which (e.g., multiple lines) is arranged parallel to a data line DL. See also Figures 4 to 10 The following example illustrates the use of a parallel arrangement of the touch drive signal line TL and the data line DL. Specifically, the touch signal line TL can be arranged on the same layer as the data line DL, and its shape, i.e., its wiring method, is consistent with that of the data line DL. With this arrangement, the touch signal line TL and the data line DL can be formed in a single patterning process, resulting in a display panel 100 with uniform brightness and touch functionality, simplifying the manufacturing process. As another example, the display panel 100 can be a self-capacitive touch display panel, with a common electrode 260 coupled to the touch signal line. During the display phase, the touch signal line provides a common electrode drive signal to the common electrode 260; during the non-display phase, the touch signal line provides a touch signal to the common electrode 260, which is then reused as a touch electrode. Again, with this arrangement, the touch signal line TL and the data line DL can be formed in a single patterning process, resulting in a display panel 100 with uniform brightness and touch functionality, simplifying the manufacturing process.

[0077] See also Figure 11 A planar pixel electrode 250 is disposed on the side of the array substrate 101 near the liquid crystal layer 103, and a common electrode 260 is located on the side of the pixel electrode 250 near the liquid crystal layer 103. Multiple slits are disposed on the common electrode 260, some of which correspond to the pixel electrode 250, thereby forming an edge electric field; others correspond to the data line DL, thereby reducing interference from other signals to the data signal. The orthographic projection of the slits on the array substrate 101 does not overlap with the orthographic projections of the gate lines GL1 and GL2 on the array substrate 101, which helps to reduce parasitic capacitance in the overlapping area and avoid signal delay on the gate lines. Between two adjacent rows of sub-pixels P in the same column, there are only three signal lines: a first gate line GL1, a second gate line GL2, and a data line DL, or a first gate line GL1, a second gate line GL2, and a touch signal line TL. The distance between two adjacent sub-pixels P is small, which helps to increase the pixel density per unit area and achieve higher display resolution.

[0078] Based on the display panel 100 described above, some embodiments of this disclosure provide a driving method for a display panel, the execution subject of which may be the display panel 100 described above, or a product including the display panel 100 described above.

[0079] See Figure 12 The driving method may include the following steps:

[0080] S101. Input gate drive signals to multiple gate lines in the display panel to turn on multiple sub-pixels in the display panel line by line.

[0081] During the display panel 100 displaying a frame of image, the GOA unit in the GOA circuit inputs gate drive signals to multiple gate lines GL in the display panel 100 to turn on multiple sub-pixels P in the display panel 100 row by row, so that each first color sub-pixel in the multiple sub-pixels P coupled to a first gate line GL1 in the multiple gate lines GL is turned on simultaneously.

[0082] In the same row of sub-pixels P, each second color sub-pixel is coupled to a second gate line GL2.

[0083] Inputting gate drive signals to multiple gate lines GL in the display panel 100 includes simultaneously inputting gate drive signals to the first gate line GL1 and the second gate line GL2 coupled to the sub-pixel P in that row, for turning on each TFT connected to the sub-pixel P in that row.

[0084] S102, multiple data lines sequentially provide input data signals for each row of sub-pixels.

[0085] The display panel 100 also includes multiple data lines DL, which include a first data line DL1 and a second data line DL2 that are alternately arranged in the row direction.

[0086] In the same row of sub-pixels P, two adjacent sub-pixels P form a sub-pixel pair 230. The two sub-pixels P in the same sub-pixel pair 230 are coupled to the same data line DL. Each pair of adjacent sub-pixel pairs 230 is coupled to a first data line DL1 and a second data line DL2, respectively. Different sub-pixels P coupled to the same data line DL are coupled to different gate lines GL. Specifically, in the same row of sub-pixels P, each first color sub-pixel is coupled to a first gate line GL1, each second color sub-pixel is coupled to a second gate line GL2, and each third color sub-pixel is alternately coupled to the first gate line GL1 and the second gate line GL2.

[0087] Multiple sub-pixels P located in the same column and of the same color include: alternating first-class sub-pixels PD1 and second-class sub-pixels PD2, each first-class sub-pixel PD1 being coupled to a first data line DL1, and each second-class sub-pixel PD2 being coupled to a second data line DL2.

[0088] The aforementioned driving method for the display panel further includes inputting data signals to each row of sub-pixels P that are turned on sequentially via multiple data lines DL. Specifically, during the display panel 100 displaying one frame of image, the first data line DL1 and the second data line DL2 transmit data signals with different polarities, and the polarity of the data signal transmitted by each of the multiple data lines DL remains unchanged.

[0089] Based on the aforementioned structure of the display panel 100, the driving method described above enables multiple sub-pixels P of the same color located in the same row and column within the AA area to have different polarities during the display of one frame of image on the display panel 100. The mixing of these multiple sub-pixels P with the same color but different polarities achieves average brightness, resulting in a better display effect. Since average brightness can be achieved within each frame, reversing the polarity of the same sub-pixel P in adjacent frames will not produce uneven brightness causing noticeable head-shaking patterns.

[0090] In some embodiments, during the display panel 100 displaying two adjacent frames of images, the data signals transmitted on the same data line DL among multiple data lines DL have different polarities. For example... Figure 4 The diagram shows the polarity of the data signals transmitted by each data line DL during the display of the first frame of two adjacent frames on the display panel 100. It can be seen that the data signals transmitted by the first data line DL1 are all positive, while the data signals transmitted by the second data line DL2 are negative. During the display of this frame, the polarities of the data signals transmitted by the first data line DL1 and the second data line DL2 are opposite and remain unchanged. Figure 7 The diagram shows the polarity of the data signals transmitted by each data line DL during the display of the second frame image in two adjacent frames on the display panel 100. It can be seen that the data signal transmitted by the first data line DL1 is electrically converted to negative, and the data signal transmitted by the second data line DL2 is electrically converted to positive, and the polarity remains unchanged during the display of the second frame image.

[0091] If liquid crystal molecules operate under a fixed voltage, their properties will solidify. Once solidified, even if the fixed voltage is removed, the liquid crystal molecules will no longer respond to changes in the applied voltage. When the display panel 100 includes liquid crystal molecules, the polarity reversal of the data signal transmitted via the same data line DL during the display of two adjacent frames can prevent the physical properties of the liquid crystal molecules from solidifying, thereby achieving better display results and extending the device's lifespan.

[0092] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
