Description

Technical Field

[0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, and specifically to a display panel and a driving method thereof, and an electronic device. Background Art

[0002] Liquid crystal displays (LCDs), currently the most widely used display devices, currently utilize a three-gate drive architecture to reduce the number of data lines to one-third of a normal drive architecture, while tripling the number of scan lines. This reduces the width and charging time of each gate pulse to one-third of that of a normal drive architecture. This is particularly true when displaying monochrome or mixed-color images, as the amplitude of the signal on the same data line constantly fluctuates. Furthermore, each gate line activates a corresponding row of pixels, resulting in insufficient optimal charging time for each row of sub-pixels.

[0003] Among them, since the data pulse of the negative polarity data signal (taking it as a negative pulse as an example) is closer to the tail of the falling edge of the gate pulse in the gate signal (taking it as a positive pulse as an example) compared to the positive polarity data signal, when the data pulse in the negative polarity data signal acts on the corresponding sub-pixel, the closing moment of the gate signal is delayed, causing the data voltage of the sub-pixels in the next row (greater than the negative pulse) to be easily mistakenly charged to the sub-pixels in this row. In order to avoid mistaken charging, the gate signal will be shifted forward to increase the distance between the corresponding gate pulse and the data voltage corresponding to the sub-pixels in the next row, thereby causing the optimal charging time of the sub-pixels in this row to be further reduced, further worsening the color deviation or low brightness phenomenon.

[0004] Therefore, the existing display panel using the three-gate driving structure has the above-mentioned problem of abnormal color of the picture, and is in urgent need of improvement. Summary of the Invention

[0046] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the said features. In addition, it should be noted that the drawings only provide structures that are closely related to the present invention, and some details that are not closely related to the invention are omitted. The purpose is to simplify the drawings and make the invention clear at a glance, rather than to indicate that the actual device is the same as the attached structure. Figure 1 The same is not a limitation of the actual device.

[0048] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase at various times in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0049] The present invention provides a method for driving a display panel, which includes but is not limited to the following embodiments and combinations of the following embodiments.

[0050] In one embodiment, if Figure 1As shown, the driving method of the display panel may include but is not limited to the following steps and a combination of the following steps.

[0051] S1. Obtain a first polarity target data voltage and a second polarity target data voltage corresponding to a target grayscale, wherein the first polarity target data voltage is greater than a reference data voltage, the second polarity target data voltage is less than the reference data voltage, and the absolute value of the difference between the first polarity target data voltage and the reference data voltage is not equal to the absolute value of the difference between the second polarity target data voltage and the reference data voltage.

[0052] Each sub-pixel in each display panel may have a corresponding gamma curve, and of course all sub-pixels may correspond to the same gamma curve; at the same time, each sub-pixel may have a corresponding grayscale table, which may include each grayscale value and the corresponding data voltage. Figure 11 As shown, the horizontal axis of the gamma curve can represent the grayscale value G acting on the corresponding sub-pixel (here, the grayscale value G is only illustrated as being in the range of [0, 255]), and the vertical axis of the gamma curve represents the luminance value T (the unit is not limited here) presented by the sub-pixel when the voltage value corresponding to the grayscale value is applied. It can be considered that the relationship between the luminance value T and the grayscale value G in different gamma curves (e.g., L1, L2, and L3) is different, but it can be considered that each gamma curve conforms to the functional relationship T = G^gamma, and the gamma values ​​of different curves are different. In particular, when the relationship between the luminance value T and the grayscale value G is set based on the characteristics of the human eye, the corresponding gamma curve is a standard gamma curve (e.g., L2, whose corresponding gamma value can be equal to 2.2). That is, it can be considered that in the standard gamma curve L2, the luminance value T and its variation are consistent with the luminance value T and its variation that the corresponding grayscale value G and its variation should have as perceived by the human eye. Therefore, the first polarity target data voltage and the second polarity target data voltage corresponding to the target grayscale in this embodiment can be understood as the data voltages corresponding to the target grayscale values ​​in the above grayscale table.

[0053] Furthermore, the display panel may have a polarity inversion function, such as frame inversion, i.e., the polarities of the data voltages applied to multiple sub-pixels in two adjacent frames may be opposite, or column inversion, i.e., the polarities of the data voltages applied to sub-pixels in two adjacent columns may be opposite. Therefore, in this embodiment, the polarities of the first polarity target data voltage and the second polarity target data voltage corresponding to the target grayscale may be opposite relative to the reference data voltage, and the absolute values ​​of the differences between the first polarity target data voltage and the reference data voltage may be approximately equal (the "approximately equal" here is caused by "the absolute value of the difference between the first polarity target data voltage and the reference data voltage is not equal to the absolute value of the difference between the second polarity target data voltage and the reference data voltage" in step S1, but the difference between the two absolute values ​​can still be considered small). Taking the display panel as an LCD panel as an example, it can be considered that the two voltages applied to the sub-pixels can cause the liquid crystal to deflect in opposite directions by almost the same angle, thereby transmitting similar amounts of light, thereby presenting similar brightness, which can be referred to as the brightness value corresponding to the target grayscale value in the gamma curve.

[0054] Specifically, for liquid crystal display panels, the reference data voltage can be understood as the voltage loaded on the common electrode. Regardless of whether the pixel electrode is loaded with the first polarity target data voltage or the second polarity target data voltage, the main difference is that the directions of deflection of the liquid crystal molecules are opposite, but the absolute value of the angle with the vertical direction can be considered as the "almost the same" as mentioned above, so that the brightness of the sub-pixel light is "approximate"; for self-luminous display panels, the reference data voltage can be understood as the data voltage corresponding to the grayscale value of 0. If the working polarities of the corresponding pixel driving circuits of the two are also set to opposite (that is, the polarities of the data voltages required when the sub-pixels emit light are different), then the data voltages acting on the two sub-pixels are the first polarity target data voltage or the second polarity target data voltage, respectively. Similarly, the brightness of the light emitted by the two sub-pixels can be considered "approximate", and the two corresponding grayscale values ​​can be considered equal.

[0055] For the convenience of description in the present invention, Figure 12 and Figure 13As shown, the display panel 100 may include a panel body 10, a plurality of source driver chips 20 electrically connected to the panel body 10, and the panel body may be provided with a plurality of sub-pixels (which may include three types of sub-pixels of different colors, R, G, and B) located in a display area AA, a plurality of gate lines (which may include m lines G1, G2, G3 to Gm, where m is a positive integer and an integer multiple of 3), and a plurality of data lines (which may include n lines D1, D2, D3 to Dn, where n is a positive integer). A gate driver circuit 30 is also provided in a non-display area NA. Here, an example is used in which a plurality of sub-pixels (including R, G, and B) are arranged in an array, the sub-pixels (including R, G, and B) located in the same column are connected to the same data line (one of D1, D2, D3 to Dn) to load the same data signal, and the sub-pixels (including R, G, and B) located in the same row are connected to the same gate line (one of G1, G2, G3 to Gm) to load the same gate signal, but the above configuration is not limited to this.

[0056] Among them, each gate line (one of G1, G2, G3 to Gm) can be electrically connected to the corresponding gate driving unit in the gate driving circuit 30 to receive the gate signal generated by it, each gate signal includes a corresponding gate pulse (the peak value of the voltage value corresponding to the gate pulse can be called "gate voltage"), and the multiple gate pulses corresponding to the multiple gate signals are arranged in sequence on the time axis to control multiple rows of sub-pixels (including multiple rows of R, multiple rows of G, and multiple rows of B) to be turned on in sequence; each source driver chip 20 can be electrically connected to multiple data lines (multiple rows of D1, D2, D3 to Dn) to Each data line (each of D1, D2, D3 to Dn) can receive a corresponding data signal, each data signal includes multiple data pulses corresponding to multiple sub-pixels (including R, G, B) (the peak value of the voltage value corresponding to the data pulse can be called "data voltage"). The arrangement order of the multiple data pulses on the time axis is the same as the arrangement order of the multiple gate pulses corresponding to the corresponding multiple sub-pixels (including R, G, B), so that the corresponding data pulse is loaded onto the corresponding sub-pixel (one of R, G, B) when the corresponding sub-pixel (one of R, G, B) is turned on.

[0057] It should be noted that if Figure 2As shown, considering that the gate signal gate and the data signal data (including the first polarity data signal data1 whose absolute value of the voltage value is greater than or equal to the reference data voltage, the second polarity data signal data2 whose voltage value is less than or equal to the reference data voltage, respectively including a plurality of first polarity data pulses pl21 and a plurality of second polarity data pulses pl22, the peak value of the voltage value corresponding to the first polarity data pulse pl21 is defined as the first polarity data voltage, and the peak value of the voltage value corresponding to the second polarity data pulse pl22 is defined as the second polarity data voltage) are loaded onto the sub-pixel of this row (for example, the green sub-pixel G) The attenuation problem will cause the corresponding gate pulse pl1 to have an intersection with the data pulse pl2 corresponding to the next row of sub-pixels (for example, the red sub-pixel R) at the end moment, resulting in the sub-pixels in this row being mischarged. The mischarging risk area A1 can be understood as the area where the data pulse pl2 corresponding to the next row of sub-pixels (for example, the red sub-pixel R) is close to the data pulse pl2 corresponding to the sub-pixel in this row (for example, the green sub-pixel G). The actual mischarging area A2 can be understood as the area where the gate pulse pl1 corresponding to the sub-pixel in this row (for example, the green sub-pixel G) overlaps with the data pulse pl2 corresponding to the sub-pixel in the next row (for example, the red sub-pixel R).

[0058] Therefore, if Figure 3 As shown, relative to Figure 2 In other words, the gate pulse pl1 corresponding to the sub-pixels in this row (e.g., the green sub-pixel G) can be moved away from the corresponding data pulse pl2 to reduce the risk of mischarging. However, this will result in a smaller overlapping area between the gate pulse pl1 and the data pulse pl2, which will result in insufficient optimal charging time for the sub-pixels in this row (e.g., the green sub-pixel G). For ease of description, the first polarity data pulse pl21 corresponding to the sub-pixels in this row is defined herein as the first polarity target data pulse pl21* (the corresponding peak voltage value is the first polarity target data voltage described above) or the second polarity target data pulse pl22* (the corresponding peak voltage value is the second polarity target data voltage described above).

[0059] Among them, taking into account the different degrees of difference between the first polarity target data voltage and the second polarity target data voltage and the corresponding gate voltage (for example, the difference between the second polarity target data voltage and the corresponding gate voltage is large), the smear of the gate pulse pl1 has a more serious impact on one of the data pulses pl2 (for example, the second polarity target data pulse pl22*). Therefore, the distance between the corresponding gate pulse pl1 should be set based on the standard that there is no overlapping area with the data pulse pl2 (that is, the next second polarity data pulse pl22) corresponding to the next row of sub-pixels (for example, the red sub-pixel R) that has a more serious impact.

[0060] S2, the first polarity target data voltage and the second polarity target data voltage are time-sharedly loaded to the same sub-pixel, or the first polarity target data voltage and the second polarity target data voltage are time-sharedly or simultaneously loaded to two different sub-pixels, so that the sub-pixels emit light to present target brightness corresponding to the target grayscale.

[0061] The "target brightness" in step S2 can be understood as the brightness value corresponding to the target grayscale in the above-mentioned gamma curve. Specifically, in this embodiment, the first polarity target data voltage or the second polarity target data voltage corresponding to the same target grayscale obtained in step S1 is differentiated from the reference voltage and is set differently. The first polarity target data voltage or the second polarity target data voltage is loaded in a time-sharing manner on the same sub-pixel, or loaded on two different sub-pixels (of the same color), and both can emit light at the target brightness, thereby limiting the first polarity target data voltage or the second polarity target data voltage.

[0062] Specifically, such as Figure 4 As shown, in this embodiment, based on the different magnitude relationships between the first polarity target data voltage and the second polarity target data voltage corresponding to the sub-pixels in this row (for example, the green sub-pixel G) and the reference data voltage, the two must also have different differences from the corresponding gate voltages (here taking the first polarity target data voltage being closer to the gate voltage as an example), the absolute value of the difference between the first polarity target data voltage and the reference data voltage is set to be unequal to the absolute value of the difference between the second polarity target data voltage and the reference data voltage (that is, the difference between the second polarity target data voltage and the reference data voltage is greater), that is, the amplitude of the first polarity target data voltage or the second polarity target data voltage is greater relative to the reference data voltage (that is, the amplitude of the second polarity target data voltage is greater here), so that the rising or falling speed when jumping from the first / second polarity target data voltage to the next first / second polarity data voltage is increased.

[0063] Understandably, Figure 4 As shown, based on this embodiment, when the data signal jumps from the first / second polarity target data voltage (that is, considering the second polarity target data voltage) corresponding to the sub-pixel of the current row (for example, the green sub-pixel G) to the first / second polarity data voltage (that is, considering the second polarity data voltage) corresponding to the sub-pixel of the next row (for example, the red sub-pixel R), the rising or falling speed when the first / second polarity target data voltage jumps to the next first / second polarity data voltage (for example, the speed at which the second polarity target data pulse pl22* corresponding to the green sub-pixel G jumps to the second polarity data pulse pl22 corresponding to the red sub-pixel R) is improved. Figure 2 As shown, this embodiment (reference but not limited to Figure 4) can avoid moving the gate pulse pl1 away from the corresponding data pulse pl2 (ie, the next second polarity data pulse pl22) (reference but not limited to Figure 3 ), the area of ​​the overlapping region (i.e., the actual mischarging region A2) between the gate pulse pl1 and the data pulse (i.e., the second polarity data pulse pl22) corresponding to the first / second polarity data voltage corresponding to the next row of sub-pixels (i.e., the red sub-pixels R) can be smaller.

[0064] From another perspective, it can also be considered that based on the actual mischarging area A2 of the same area, in this embodiment, since the rising or falling speed of the first / second polarity target data voltage when jumping to the next first / second polarity data voltage is improved, it is more conducive to forming a smaller actual mischarging area A2. Therefore, the distance that the gate pulse pl1 moves in the direction away from the data pulse pl2 corresponding to the next row of sub-pixels can be reduced to increase the area of ​​the overlapping area between the gate pulse pl1 and each corresponding data pulse pl2, thereby increasing the effective charging time of each sub-pixel, so as to improve the color cast of the mixed color picture or the low brightness of the monochrome picture.

[0065] Of course, if Figure 6 As shown, based on Figure 4 The gate pulse pl1 can also be moved further away from the data pulse corresponding to the second polarity data voltage corresponding to the next row of sub-pixels (i.e., the red sub-pixels R) so that there is no overlapping area between the two, that is, the above-mentioned actual mischarging area A2 does not exist, which can further reduce the risk of the above-mentioned mischarging.

[0066] It should be noted that the "target brightness" in this embodiment can refer to a brightness range. It can be considered that the brightness presented by two sub-pixels or one sub-pixel loaded with the first polarity target data voltage and the second polarity target data voltage belongs to the target brightness. The difference between the two brightnesses can be considered to be almost unrecognizable by the human eye. At the same time, the effective charging time of the sub-pixels can be made more sufficient to improve the above-mentioned color cast of the picture or the low brightness of the monochrome picture.

[0067] In one embodiment, the above step S2 may include but is not limited to the following steps: applying a gate voltage to the sub-pixel to turn on the sub-pixel, and applying the first polarity target data voltage and the second polarity target data voltage to the same sub-pixel in a time-sharing manner, or applying the first polarity target data voltage and the second polarity target data voltage to two different sub-pixels in a time-sharing manner or simultaneously; wherein, Figure 4As shown, the gate voltage (the peak value of the voltage corresponding to the gate pulse pl1) is greater than the first polarity target data voltage (acting on the luminous sub-pixel (for example, the green sub-pixel G) and greater than the peak value of the voltage value of the reference data voltage) and the second polarity target data voltage (acting on the luminous sub-pixel (for example, the green sub-pixel G) and less than the voltage value of the reference data voltage), and the absolute value of the difference between the first polarity target data voltage and the reference data voltage is less than the absolute value of the difference between the second polarity target data voltage and the reference data voltage; or as Figure 5 As shown, the gate voltage is less than the first polarity target data voltage and the second polarity target data voltage, and the absolute value of the difference between the first polarity target data voltage and the reference data voltage is greater than the absolute value of the difference between the second polarity target data voltage and the reference data voltage.

[0068] Understandably, Figure 4 As shown, at this time, the polarity of the gate voltage is the same as the polarity of the first polarity target data voltage. It can be considered that the risk of mischarging caused by the tail of the gate pulse pl1 in the next second polarity data pulse pl22 is greater. Therefore, in this embodiment, the absolute value of the difference between the second polarity target data voltage and the reference data voltage is set to be larger to speed up the jump (rise) speed of the data signal from the second polarity target data voltage corresponding to the sub-pixel of this row (for example, the green sub-pixel G) to the second polarity data voltage corresponding to the sub-pixel of the next row (that is, the red pixel R), so that the distance that the gate pulse pl1 moves away from the data pulse pl2 corresponding to the sub-pixel of the next row (that is, the red pixel R) can be reduced, so as to increase the effective charging time of the sub-pixel, so as to improve the above-mentioned color shift of the picture or the low brightness of the monochrome picture.

[0069] Similarly, if Figure 5 As shown, at this time, the polarity of the gate voltage is the same as the polarity of the second polarity target data voltage. It can be considered that the risk of mischarging caused by the tail of the gate pulse pl1 in the next first polarity data pulse pl21 is greater. Therefore, in this embodiment, the absolute value of the difference between the first polarity target data voltage and the reference data voltage is set to be larger to speed up the speed of the data signal jumping (falling) from the second polarity target data voltage corresponding to the sub-pixel of this row (for example, the green sub-pixel G) to the second polarity data voltage corresponding to the sub-pixel of the next row (that is, the red pixel R), so that the distance that the gate pulse pl1 moves away from the data pulse pl2 corresponding to the sub-pixel of the next row (that is, the red pixel R) can be reduced, so as to increase the effective charging time of the sub-pixel, so as to improve the above-mentioned color cast of the picture or the low brightness of the monochrome picture.

[0070] In one embodiment, if Figure 4 and Figure 5As shown, the charging or discharging speed of the first polarity target data voltage converted to the reference data voltage is not equal to the charging or discharging speed of the second polarity target data voltage converted to the reference data voltage. The difference in charging and discharging speeds in this embodiment is not due to the different degrees of difference between the first polarity target data voltage and the second polarity target data voltage and the reference data voltage. Instead, it can be achieved by differentiating the PWRC (Power Control) of the first data signal data1 including the first polarity target data voltage and the second data signal data2 including the second polarity target data voltage in the source driver chip. For example, the PWRC of the first data signal data1 including the first polarity target data voltage and the second data signal data2 including the second polarity target data voltage can be 100% and 120%, respectively. Alternatively, the charge and discharge speeds of the first data signal data1 and the second data signal data2 can be set differently by enabling the CTD (Charge Time Detection) function of one of the two. It can be assumed that a larger PWRC value indicates a faster charge and discharge speed, and enabling CTD also results in a faster charge and discharge speed than disabling CTD.

[0071] For ease of description, Figure 4 and Figure 5 In the example, the first polarity data voltage or the second polarity data voltage corresponding to the blue sub-pixel B and the red sub-pixel R both belong to the reference data voltage, that is, the jump from the first / second polarity target data voltage to the first / second polarity data voltage can be equivalent to the jump from the first / second polarity target data voltage to the reference data voltage, and the jump from the first / second polarity data voltage to the first / second polarity target data voltage can be equivalent to the jump from the reference data voltage to the first / second polarity target data voltage.

[0072] Specifically, such as Figure 4 As shown, when the risk of mischarging caused by the tail of the gate pulse pl1 in the second polarity data pulse pl22 is greater, the charging or discharging speed of the second polarity target data voltage corresponding to the second polarity target data pulse pl22* into the reference data voltage can be faster through but not limited to the above two methods, so as to further improve the speed of converting the second polarity target data voltage into the reference data voltage in the second data signal data2; Figure 5 As shown, when the risk of mischarging caused by the tail of the gate pulse pl1 in the first polarity data pulse pl22 is greater, the charging or discharging speed of the first polarity target data voltage corresponding to the first polarity target data pulse pl21* can be set to be faster to further improve the speed of converting the first polarity target data voltage to the reference data voltage in the second data signal data2 by, but not limited to, the above two methods.

[0073] Furthermore, to further improve the speed of converting the first polarity target data voltage or the second polarity target data voltage to the reference data voltage, the charge and discharge speeds for converting the reference voltage to the first polarity target data voltage or the second polarity target data voltage may be differentiated. Specific methods may include, but are not limited to, the differentiated settings of PWRC and CTD described above.

[0074] In one embodiment, if Figure 7 As shown, the display panel includes a plurality of sub-pixels, and the plurality of sub-pixels include a first sub-pixel and a second sub-pixel. Step S1 (taking the target grayscale corresponding to the first polarity target data voltage as an example) may include but is not limited to the following steps.

[0075] S11, obtaining a first sub-polarity target data voltage corresponding to the first sub-pixel and a second sub-polarity target data voltage corresponding to the second sub-pixel in the first polarity target data voltage, the turn-on time of the first sub-pixel is different from the turn-on time of the second sub-pixel, and the first sub-polarity data voltage is not equal to the second sub-polarity data voltage.

[0076] It should be noted that the gate signal gate and data signal data generated by the driver chip are generally transmitted from one side of the display panel to the opposite side, resulting in different degrees of attenuation of the gate voltage and data voltage loaded on the sub-pixels at different positions compared to the voltage generated by the source of the driver chip. Even if they correspond to the same grayscale, the corresponding same voltage value has different attenuation degrees on the sub-pixels at different positions, resulting in different luminous brightness of the sub-pixels at different positions.

[0077] Among them, the first sub-pixel and the second sub-pixel with different opening moments in step S11 can be understood as the different moments when they receive the corresponding data voltages. That is, if no intervention is made, the attenuation degree of the same data voltage corresponding to the same grayscale on the first sub-pixel and the second sub-pixel is different.

[0078] Based on step S11, the above step S2 may include but is not limited to the following steps.

[0079] S21 , applying the first sub-polarity target data voltage to the first sub-pixel, and applying the second sub-polarity target data voltage to the second sub-pixel, so that both the first sub-pixel and the second sub-pixel emit light to present the target brightness.

[0080] It can be understood that in step S11 of this embodiment, the two data voltages corresponding to the same grayscale (i.e., target grayscale) of the first sub-pixel and the second sub-pixel at different positions (for example, for the positive polarity data voltage, both are the first polarity target data voltage) are differentiated and set to be the first sub-polarity target data voltage and the second sub-polarity target data voltage of different sizes, respectively, to compensate for the difference in brightness corresponding to the same grayscale caused by the different degrees of signal attenuation mentioned above.

[0081] Specifically, such as Figure 8 As shown, no matter for the first data signal data1 or the second data signal data2, it can be considered that along the positive direction of the time axis t, as analyzed above, any data signal will find an increasingly greater degree of attenuation. Here, the sub-pixel acted upon by the multiple data voltages in the first stage t1 in the first data signal data1 or the second data signal data2 can be defined as one of the first sub-pixel and the second sub-pixel, and the sub-pixel acted upon by the multiple data voltages in the second stage t2 in the first data signal data1 or the second data signal data2 can be defined as the other of the first sub-pixel and the second sub-pixel.

[0082] For ease of description, the sub-pixels affected by the multiple data voltages in the first stage t1 and the second stage t2 of the first data signal data1 are defined as the first sub-pixel and the second sub-pixel, respectively. Since the data line first transmits the first sub-polarity target data voltage acting on the first sub-pixel and then transmits the second sub-polarity target data voltage acting on the second sub-pixel, it can be considered that the distance between the first sub-pixel and the driver chip is smaller than the distance between the second sub-pixel and the driver chip, that is, the second sub-polarity target data voltage will be more severely attenuated than the first sub-polarity target data voltage. Therefore, if Figure 8 As shown, in this embodiment, the second sub-polarity target data voltage (belonging to the first polarity target data voltage) in the first data signal data1 in the second stage t2 is set to be greater than the first sub-polarity target data voltage (also belonging to the first polarity target data voltage) in the first stage t1 to compensate for the brightness difference caused by the attenuation difference.

[0083] Similarly, the second polarity target data voltage in the second data signal data2 in the second stage t2 may also be set to be greater than the second polarity target data voltage in the first stage t1 to compensate for the brightness difference caused by the attenuation difference.

[0084] In one embodiment, if Figure 9 As shown, the step S1 (taking the target grayscale corresponding to the first polarity target data voltage as an example) may include but is not limited to the following steps.

[0085] S13 , obtaining a first polarity initial data voltage corresponding to the target grayscale and a first polarity compensation voltage corresponding to the sub-pixel.

[0086] Among them, since the data voltage is generated by the source driver chip, and the distance between the source driver chip and the row of green sub-pixels G closest to the source driver chip will also cause a certain attenuation of the data voltage, therefore, it is possible to experimentally measure the attenuation value of the first polarity data voltage caused by this distance (i.e., the first polarity compensation voltage), and the voltage value corresponding to the target grayscale when the above-mentioned attenuation of the first polarity data voltage is not taken into account (i.e., the first polarity initial data voltage).

[0087] S14 , determining the first polarity target data voltage according to the first polarity initial data voltage and the first polarity compensation voltage.

[0088] Understandably, Figure 8 As shown, since the first first-polarity target data pulse p121* or the first second-polarity target data pulse p122* on the time axis t corresponds to the row of green sub-pixels G closest to the driver chip, it can be considered that the setting of the first first-polarity target data pulse p121* and the first second-polarity target data pulse p122* has taken into account the attenuation of the data signal from the source driver chip to the "nearest row of green sub-pixels G" (i.e., the first polarity compensation voltage). The corresponding first polarity target data voltage can be superimposed on the first polarity initial data voltage corresponding to the target grayscale to obtain the corresponding first polarity target data voltage. Therefore, it can be considered that the brightness of the "nearest row of green sub-pixels G" under the influence of the first first-polarity target data pulse p121* or the first second-polarity target data pulse p122* can be equal to the above-mentioned target brightness.

[0089] Further, if Figure 8 As shown above, Figure 4 Taking the example of the greater risk of mischarging caused by the tail of the gate pulse pl1 in the second polarity data pulse pl22, there is at least one row of green sub-pixels G, whose corresponding second polarity target data voltage of the second polarity target data pulse pl22* can be greater than the first polarity target data voltage of the corresponding first polarity target data pulse pl21*. For example, the absolute value of the difference between the two is △V, and △V can be equal to 0.2V.

[0090] In one embodiment, if Figure 10 As shown, the display panel includes a plurality of sub-pixels, and the plurality of sub-pixels include a third sub-pixel and a fourth sub-pixel. Step S1 (taking the target grayscale corresponding to the first polarity target data voltage as an example) may include but is not limited to the following steps.

[0091] S12, obtaining a third sub-polarity target data voltage corresponding to the third sub-pixel and a fourth sub-polarity target data voltage corresponding to the fourth sub-pixel in the first polarity target data voltage, the turn-on time of the third sub-pixel and the turn-on time of the fourth sub-pixel are both earlier than or later than the turn-on time of the fifth sub-pixel, the turn-on time of the third sub-pixel is different from the turn-on time of the fourth sub-pixel, and the third sub-polarity data voltage is equal to the fourth sub-polarity data voltage.

[0092] Similarly, the third sub-pixel, the fourth sub-pixel and the fifth sub-pixel with different turn-on times in step S12 can also be understood as the three receiving the corresponding data voltages at different times, that is, if no intervention is made, the attenuation degree of the same data voltage corresponding to the same grayscale on the three is different.

[0093] Furthermore, for the sake of ease of description, the area closer to the driver chip and the area farther away are referred to as the proximal area and the distal area, respectively. Since the data signal will be transmitted to the proximal area first, the attenuation rate of the gate voltage and the data voltage in the proximal area is much greater than the attenuation degree in the distal area, resulting in a smaller signal amplitude transmitted to the distal area, but the attenuation degree is comparable.

[0094] Based on step S12, the above step S2 may include but is not limited to the following steps.

[0095] S22 , applying the third sub-polarity target data voltage to the third sub-pixel, and applying the fourth sub-polarity target data voltage to the fourth sub-pixel, so that both the third sub-pixel and the fourth sub-pixel emit light to present the target brightness.

[0096] Specifically, such as Figure 8 As shown, the fifth sub-pixel in step S12 of this embodiment can be understood as being located in the proximal region (i.e., the corresponding first polarity target data voltage is located in the first stage t1), and the third sub-pixel and the fourth sub-pixel are both located in the distal region (i.e., the corresponding two first polarity target data voltages are both located in the second stage t2). As discussed above, since the third sub-polarity target data voltage and the fourth sub-polarity target data voltage located in the second stage t2 have a small attenuation difference when transmitted to the third sub-pixel and the fourth sub-pixel respectively, the two can be set to be equal to save the amount of calculation and storage of the data voltage.

[0097] Of course, for two sub-pixels that are close to each other (the time interval between the corresponding two data voltages is short, or the distance between the corresponding two data lines is small), the two corresponding data voltages can also be set to be the same to save the calculation and storage of the data voltage.

[0098] Furthermore, for two sub-pixels that are far apart (the time interval between the two corresponding data voltages is long, or the distance between the two corresponding data lines is large), the two corresponding data voltages can also be set to be different, and the data voltages corresponding to the sub-pixels between the two can be obtained by linear interpolation to save the calculation and storage of the data voltages.

[0099] The present invention also provides a display panel, comprising: a plurality of the above-mentioned sub-pixels; a plurality of the above-mentioned data lines, each of the data lines being connected to a corresponding plurality of the sub-pixels to transmit a corresponding data signal, the data signal comprising a plurality of data voltages corresponding to the plurality of the sub-pixels; wherein the plurality of the sub-pixels comprise a first sub-pixel and a second sub-pixel connected to the same or different data lines, and the plurality of data voltages in the corresponding same or different data signals comprise a first polarity target data voltage corresponding to the first sub-pixel and a second polarity target data voltage corresponding to the second sub-pixel at the target grayscale; or, the same data signal comprises a first polarity target data voltage and a second polarity target data voltage corresponding to the same sub-pixel at different times at the target grayscale.

[0100] wherein the first polarity target data voltage is greater than a reference data voltage, the second polarity target data voltage is less than the reference data voltage, and an absolute value of a difference between the first polarity target data voltage and the reference data voltage is not equal to an absolute value of a difference between the first polarity target data voltage and the reference data voltage;

[0101] Among them, the first sub-pixel and the second sub-pixel corresponding to the first polarity target data voltage and the second polarity target data voltage, or the same sub-pixel corresponding to the first polarity target data voltage and the second polarity target data voltage, all emit light to present the target brightness corresponding to the target grayscale.

[0102] As discussed above, in this embodiment, there is no limitation on whether the first sub-pixel and the second sub-pixel are connected to the same data line, and there is no limitation on whether the first polarity target data voltage and the second polarity target data voltage with different polarities corresponding to the same target grayscale act on the same sub-pixel, or act on the above-mentioned different first sub-pixels and second sub-pixels.

[0103] It can be understood that the present embodiment does not limit the sub-pixels on which the first polarity target data voltage and the second polarity target data voltage act specifically. However, by differentiating the gaps between the two and the reference data voltage, combined with the above discussion, it can be seen that for this display panel, it is more conducive to forming a smaller actual mischarging area A2, so that the distance that the gate pulse pl1 moves in the direction away from the corresponding data pulse pl2 corresponding to the next row of sub-pixels (i.e., the red pixel R) can be reduced, so as to increase the area of ​​the overlapping area between the gate pulse pl1 and each corresponding data pulse pl2, thereby increasing the effective charging time of each sub-pixel, so as to improve the color cast of the mixed-color picture or the low brightness of the monochrome picture.

[0104] In one embodiment, the display panel further includes: a plurality of the above-mentioned gate lines, each of the gate lines being electrically connected to the corresponding plurality of sub-pixels to transmit corresponding gate signals, the gate signals including gate voltages for turning on the corresponding plurality of sub-pixels; wherein the gate voltage is greater than the first polarity target data voltage and the second polarity target data voltage, and the absolute value of the difference between the first polarity target data voltage and the reference data voltage is less than the absolute value of the difference between the first polarity target data voltage and the reference data voltage; or, the gate voltage is less than the first polarity target data voltage and the second polarity target data voltage, and the absolute value of the difference between the first polarity target data voltage and the reference data voltage is greater than the absolute value of the difference between the first polarity target data voltage and the reference data voltage.

[0105] Specifically, you can combine the above Figure 4 and Figure 5 to understand the discussion.

[0106] In one embodiment, the plurality of sub-pixels include a third sub-pixel and a fourth sub-pixel connected to the same data line or respectively connected to two different data lines, and the third sub-pixel and the fourth sub-pixel are respectively connected to two different gate lines to have different turn-on moments; wherein, the plurality of data voltages in the corresponding data signal include a first sub-polarity target data voltage corresponding to the third sub-pixel and a second sub-polarity target data voltage corresponding to the fourth sub-pixel under the target grayscale, and the first sub-polarity target data voltage is not equal to the second sub-polarity target data voltage; wherein, the third sub-pixel and the fourth sub-pixel respectively loaded with the first sub-polarity target data voltage and the second sub-polarity target data voltage both emit light to present the target brightness.

[0107] For details, refer to the above Figure 8According to the discussion above, the sub-pixel acted upon by the multiple data voltages in the first stage t1 in the first data signal data1 or the second data signal data2 can be defined as one of the third sub-pixel and the fourth sub-pixel, and the sub-pixel acted upon by the multiple data voltages in the second stage t2 in the first data signal data1 or the second data signal data2 can be defined as the other of the third sub-pixel and the fourth sub-pixel.

[0108] For ease of description, the sub-pixels affected by the multiple data voltages in the first stage t1 and the second stage t2 of the first data signal data1 are defined as the third sub-pixel and the fourth sub-pixel. Since the data line first transmits the first sub-polarity target data voltage acting on the third sub-pixel and then transmits the second sub-polarity target data voltage acting on the second sub-pixel, it can be considered that the distance between the third sub-pixel and the driver chip is smaller than the distance between the fourth sub-pixel and the driver chip, that is, the attenuation of the second sub-polarity target data voltage is more serious than that of the first sub-polarity target data voltage. Therefore, if Figure 8 As shown, in this embodiment, the second sub-polarity target data voltage (belonging to the first polarity target data voltage) in the first data signal data1 in the second stage t2 is set to be greater than the first sub-polarity target data voltage (also belonging to the first polarity target data voltage) in the first stage t1, so as to compensate for the brightness difference caused by the attenuation difference, so as to achieve that the third sub-pixel and the fourth sub-pixel both emit light to present almost the same target brightness.

[0109] Similarly, if Figure 8 As shown, the second polarity target data voltage in the second data signal data2 in the second stage t2 may also be set to be greater than the second polarity target data voltage in the first stage t1 to compensate for the brightness difference caused by the attenuation difference.

[0110] The present invention also provides an electronic device comprising any display panel as described above.

[0111] The present invention provides a display panel, a driving method thereof, and an electronic device. Based on a first polarity target data voltage (greater than a reference data voltage) and a second polarity target data voltage (less than the reference data voltage) with different polarities for the same target grayscale, the absolute value of the difference between the first polarity target data voltage and the reference data voltage is set to be unequal to the absolute value of the difference between the second polarity target data voltage and the reference data voltage, and the first polarity target data voltage or the second polarity target data voltage is time-sharedly loaded to the same sub-pixel, or the first polarity target data voltage and the second polarity target data voltage are time-sharedly or simultaneously loaded to two different sub-pixels. While causing the sub-pixels to emit light to present a target brightness corresponding to the target grayscale, the distance that the gate pulse moves in the direction away from the data pulse corresponding to the next row of sub-pixels can be reduced, thereby increasing the area of ​​the overlapping region between the gate pulse and each corresponding data pulse pl2, thereby increasing the effective charging time of each sub-pixel, thereby improving the color cast of a mixed-color picture or the low brightness of a monochrome picture.
