Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not limiting. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms "first," "second," and the like in this application are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display device provided in the present application, where the display device 100 includes a driver (not shown) and scan lines (gate, G) and data lines (S) disposed in a crisscross manner.
The scan lines and the data lines are connected to a driver, and optionally, the driver may specifically include a gate driver and a source driver, where the gate driver is connected to the scan lines and is used for providing gate scan signals to the scan lines, and the source driver is connected to the data lines and is used for providing data signals to the data lines.
Alternatively, this embodiment shows a driving architecture, and all the sub-pixels may be divided into a plurality of display units, each including 6 columns, i.e., 6 data lines, according to three-color sub-pixels of red (R), green (G), and blue (B) and positive and negative polarities.
Specifically, the display area is formed with 6 data channels formed by 6*M data lines, when M2, the nth data channel is formed by connecting the nth data line to the n+6th (M-1) data line. As can be seen from the figure, in the same row of sub-pixels, the first 6 sub-pixels are b+, G-, r+, B-, g+, R-, respectively, repeated starting from the 7 th sub-pixel and starting from b+. Thus, the 1 st data line and the 7 th data line are connected to form a first data channel D1, the 2 nd data line and the 8 th data line are connected to form a second data channel D2, and so onPushing. In other embodiments, the data channels and the data lines may be divided according to a 1:3 or a 1:4 method, for example, the 1 st data line, the 7 th data line and the 13 th data line are connected to form a first data channel D1, the 2 nd data line, the 8 th data line and the 14 th data line are connected to form a second data channel D2, and so on.
With further reference to fig. 2, fig. 2 is a schematic driving diagram corresponding to the first data channel D1 in fig. 1, wherein B1, B2, B3, B4, B5, and B6 represent driving sequences.
Taking the subpixel B1 driving phase as an example: g1 is high level, sub-pixel B1 is opened, sub-pixels B2-B6 are closed, data channel D1 inputs data signal to data line S1 and data line S7, in this stage, because there is no sub-pixel on the left side of data line S1, there is adjacent sub-pixel R1-R3 on the left side of data line S7, because there is parasitic capacitance (between data line S7 and sub-pixel R1-R3) between data line and pixel electrode, will influence the display effect of sub-pixel R1-R3.
The driving stages of the sub-pixels B2, B3, B4, B5, B6 and the driving stages corresponding to the other data channels are similar to the driving stage of the sub-pixel B1, and will not be described herein again, it will be understood that the data input by one data channel only drives one sub-pixel at the same time, but may have a display effect on other sub-pixels adjacent to the plurality of data lines corresponding to the data channel.
It can be understood that the display device in this embodiment is a liquid crystal display device, and mainly includes a display panel and a backlight module, where the display panel includes a TFT substrate, a color film substrate, and a liquid crystal layer therebetween, and the scanning lines, the data lines, and the pixel electrodes of each sub-pixel are all located on the TFT substrate.
Referring to fig. 3, fig. 3 is a flow chart of an embodiment of a display driving method provided in the present application, where the method includes:
step S31: a first image signal of a display area is acquired, wherein the first data signal at least comprises an original gray scale value of a target sub-pixel.
Wherein the display area is as shown in the figure1, the display area is formed by 6*M data lines into 6 data channels, when M2, the nth data channel is formed by connecting the nth data line to the n+6th (M-1) data line.
Optionally, the first image signal is a gray-scale value of each pixel of the corresponding display area in a frame image, that is, an original gray-scale value. It should be understood that 1024 gray levels are taken as an example in the embodiment of the present application, and 1024 gray levels divide the brightness into 1024 levels, i.e. 0 to 1023 total 1024 levels, and in other embodiments, 256 gray levels and 512 gray levels can be used, which is not limited herein.
Step S32: and determining a compensation coefficient and compensation data according to the original gray scale value.
The compensation coefficient may also be referred to as a compensation multiplying power, and is used for adjusting the finally determined compensation value, and the compensation data is used for preparing for determining the compensation value subsequently.
Optionally, in an embodiment, as shown in fig. 4, fig. 4 is a schematic flow chart of an embodiment of step S32 in fig. 3, and step S32 may include:
step S321: and determining a first compensation level and a second compensation level according to the original gray scale value.
The compensation levels may be different according to gray scale values, for example, 1024 gray scales may be divided into 32 levels or 64 levels, which is not limited herein, wherein the first compensation level is used to determine the compensation coefficient and the second compensation level is used to determine the compensation data.
Optionally, in an embodiment, the first compensation level is determined using the following formula:
optionally, in an embodiment, the second compensation level is determined using the following formula:
wherein A is a first compensation level, B is a second compensation level,for the original gray level, +.>As a rounding function.
Step S322: a compensation coefficient is determined based on the first compensation level.
It will be appreciated that, depending on the above-described ranking, the first compensation ranking and the compensation coefficient may be determined in a one-to-one correspondence, or a graph may be established. For example, the 1024 gray scales are divided into 32 levels, so that each level has 32 gray scales, and the compensation coefficients are divided into 32 levels to obtain 32 compensation coefficients, and after the first compensation level A is calculated by the above formula, the corresponding compensation coefficient is determined by looking up a table. For example, the following relationship may be established:
step S323: and determining compensation data according to the second compensation level.
It will be appreciated that the second compensation level and the compensation data may be determined in a one-to-one correspondence or a graph may be established in accordance with the above-described level division. For example, the 1024 gray scales are divided into 64 levels, so that each level has 16 gray scales, the compensation data are divided into 64 levels to obtain 64 compensation data, the second compensation level B is calculated by the above formula, and the corresponding compensation data are determined by looking up a table. It is noted that the compensation data herein relates to the average value of the positive and negative voltages of the current gray scale.
For example, the following relationship may be established:
step S33: and determining a first influence quantity and a second influence quantity according to the compensation data, wherein the first influence quantity represents the influence of the current data line on the previous frame image, and the second influence quantity represents the influence of the current data line on the current frame image.
Fig. 5 is a schematic diagram of a display screen according to an embodiment, as shown in fig. 5. Taking column inversion as an example, assuming that the middle area displays green (L255) and the other areas display white (L64), it is known that data on one data line is divided into three segments in one frame, an up portion is L64, a green portion is L255, and a down portion is L64; the voltage of the middle L255 part is higher than that of the up part and the down part, and the line scanning is taken as an example from top to bottom, and the data of the part affects the up part of the frame and also affects the down part of the previous frame;
as shown in fig. 6, fig. 6 is a waveform diagram of the data signal corresponding to fig. 5. The up part, it can be seen that because the voltage is influenced to decrease, the voltage difference between the data voltage and the common voltage Vcom becomes larger and the brightness increases because of the negative polarity; in the down part, the voltage is still affected to drop, and since the previous frame is positive, the voltage difference between the data voltage and the common voltage Vcom becomes small, and the brightness is lowered.
Therefore, the present embodiment needs to determine the first influence amount of the current data line on the previous frame image and the second influence amount of the current data line on the current frame image, respectively.
Optionally, in step S33, an influence factor is determined according to the compensation data, and then an influence amount is determined according to the influence factor.
The influence factors, in particular the first influence factor and the second influence factor, are determined from the compensation data.
Determining a driving sequence of the sub-pixels in the data channel corresponding to the target sub-pixels; determining a first influence factor according to compensation data corresponding to a plurality of sub-pixels driven before a target sub-pixel; and determining a second influence factor according to the compensation data corresponding to the plurality of sub-pixels driven after the target sub-pixel.
Referring to fig. 1 and 7, fig. 7 is a schematic diagram of a sub-pixel driving sequence in an embodiment. Since only one subpixel is driven at the same time when data is input in one data channel, display effects are generated on other subpixels corresponding to the data channel.
Therefore, when considering the first influencing factor of the target subpixel, it is necessary to accumulate the previous compensation data according to the driving order.
Specifically, the sum of the compensation data of the target subpixel and the compensation data corresponding to a plurality of subpixels driven before the target subpixel is used as the first influence factor. The following formula can be specifically adopted:
taking the sub-pixel B4 corresponding to the first data channel D1 as an example:
=/>+/>+/>+/>
therefore, when considering the second influencing factor of the target subpixel, it is necessary to accumulate the compensation data later according to the driving order.
Specifically, the sum of the compensation data of all the sub-pixels is used as a first intermediate value, and the sum of the compensation data corresponding to the target sub-pixel and the plurality of sub-pixels driven before the target sub-pixel is used as a second intermediate value, and the difference between the first intermediate value and the second intermediate value is used as a second influence factor. The following formula can be specifically adopted:
where V represents the total number of rows, and let v=6, take the sub-pixel B4 corresponding to the first data channel D1 as an example:
=/>+/>+/>+/>+/>+/>--/>-/>-/>the method comprises the following steps:
=/>+/>
the influence amounts are described further below, in particular the first influence amount is determined on the basis of the first influence factor and the second influence amount is determined on the basis of the second influence factor.
Wherein the first influence amount is determined using the following formula:
wherein the second influence amount is determined using the following formula:
wherein,for the first influencing quantity, +.>For the second influencing quantity, ++>For the first influencing factor, +.>For the second influencing factor, +.>As a rounding function.
It will be appreciated that 1024 in the above formula is the total gray level, and the above formula indicates that the compensation is performed only when the influence factor (i.e. the accumulated value of the compensation data of the plurality of sub-pixels) is greater than 1024, and 1024 can be adjusted according to the total gray level of the display device.
Step S34: and determining a third influence quantity according to the first influence quantity and determining a fourth influence quantity according to the second influence quantity, wherein the third influence quantity represents the influence of the adjacent data line on the previous frame image, and the fourth influence quantity represents the influence of the adjacent data line on the current frame image.
As shown in fig. 8, fig. 8 is a schematic diagram of a right adjacent data line, taking the data channel D1 as an example, the current data line is on the left side of the sub-pixel, and the adjacent data line is on the right side of the sub-pixel. Then, the compensation value is 0 if the right-most column of subpixels has no adjacent data line, and the third influence is as follows for other columns of subpixels:
the fourth influencing quantity is as follows:
note that if n is greater than resolution 3 (e.g., 3840×1920, then n=3840), then:
as shown in fig. 9, fig. 9 is a schematic diagram of a structure of a left adjacent data line, taking the data channel D1 as an example, the current data line is on the right side of the sub-pixel, and the adjacent data line is on the left side of the sub-pixel. Then, the left-most column of subpixels has no adjacent data line, and the compensation value is 0, and for other columns of subpixels, the third influence is as follows:
the fourth influencing quantity is as follows:
note that if n=1, then:
step S35: and determining a compensation value according to the compensation coefficient, the third influence amount and the fourth influence amount.
Optionally, as shown in fig. 10, fig. 10 is a schematic flow chart of an embodiment of step S35 in fig. 3, where step S35 may include:
step S351: the compensation amount is determined based on a difference between the third influence amount and the fourth influence amount, or a difference between the fourth influence amount and the third influence amount.
It will be appreciated that, considering that the pixel electrode has both positive and negative polarities, in one embodiment, since the effect of the adjacent data line on the previous frame is the same as the polarity of the corresponding pixel of the present frame, the data needs to be subtracted in the opposite direction, so this part of compensation is subtracted; this partial compensation is additive because the adjacent data lines affect the frame in opposite polarity to the corresponding pixels in the frame, and the data needs to be added in the forward direction. Accordingly, the compensation amount may employ the following formula:
in another embodiment, since the effect of the adjacent data line on the previous frame is opposite to the polarity of the corresponding pixel of the present frame, the effect is opposite, and the data needs to be added in the forward direction, so this part of compensation is added; since the effect of adjacent data lines on the frame is the same as the polarity of the corresponding pixels of the frame, and the effect is the same, the data needs to be subtracted reversely, so the compensation of the part is the subtraction.
