"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, which may also change accordingly when the absolute position of the object being described changes.
At present, the contrast ratio of a common liquid crystal display module is generally low, and in a stacked-screen (BD Cell) display device, two liquid crystal display panels are stacked and then displayed, so that the contrast ratio can be greatly improved. Fig. 1 is a schematic view of a stacked-screen display apparatus provided in an example, and as shown in fig. 1, the stacked-screen display apparatus includes: the backlight module 30, the first panel 10 located at the light-emitting side of the backlight module 30, and the second panel 20 located at the side of the first panel 10 far away from the backlight module 30. In which the first panel 10 displays a gray scale image and the second panel 20 displays an RGB color image.
Fig. 2 is a diagram of a superimposed effect of plan views of a first panel and a second panel provided in an example, as shown in fig. 2, the first panel 10 includes a plurality of first pixels, and the second panel 20 includes a plurality of second pixels, each of the first pixels corresponding to the plurality of second pixels. Each of the second pixels may include a plurality of sub-pixels, for example, a red sub-pixel, a blue sub-pixel, and a green sub-pixel. To avoid the double screen overlap creating rainbow patterns, in some examples, the second pixel is square, the first pixel is inverted "V" shaped, and the area of the first pixel is 4 times the area of the second pixel. Under the condition of accurate alignment, the orthographic projection of the first pixel on the backlight module 30 is overlapped with the orthographic projection of the second pixel on the backlight module 30, wherein the second pixel is 4 rows and 2 columns.
The laminated screen display equipment has higher requirement on the fitting precision of the two display panels, and if the laminated screen display equipment is staggered, the problem of bright and dark shadows appears. For example, when displaying an image, the brightness of the light emitted from one of the second pixels a needs to reach L250, and the brightness of the light emitted from the adjacent one of the second pixels b needs to reach L0, in this case, the first pixel a corresponding to the second pixel a needs to provide higher brightness, such as L255; the first pixel B corresponding to the second pixel B can provide lower brightness to reduce power consumption. If the two display panels are misaligned, for example, the first pixel a is misaligned and at least a part of the first pixel a is opposite to the second pixel b, the actual brightness of the second pixel b is slightly bright, and a bright shadow appears; on the contrary, if the first pixel B is dislocated and at least a part of the first pixel B is opposite to the second pixel a, the actual brightness of the second pixel a is darker and a dark shadow appears.
The present disclosure provides a driving method of a display module, wherein the display module is a stacked-screen display module and is used for being arranged opposite to a backlight module. The display module comprises a first panel and a second panel, wherein the second panel is positioned on the light emitting side of the first panel, the first panel and the second panel can be liquid crystal display panels, and the light emitting side of the first panel is the side far away from the backlight module. The first panel comprises a plurality of first pixels, the second panel comprises a plurality of second pixels, and each first pixel and the plurality of second pixels are overlapped in the thickness direction of the display module. The overlapping of the first pixel and the plurality of second pixels in the thickness direction of the display module means that the orthographic projection of the first pixel on a reference plane perpendicular to the thickness direction of the display module overlaps with the orthographic projection of the plurality of second pixels on the reference plane. For example, the positional relationship of the plurality of first pixels of the first panel and the plurality of second pixels of the second panel may be as shown in fig. 2.
Fig. 3 is a schematic view of a driving method provided in some embodiments of the present disclosure, and as shown in fig. 3, the driving method includes S10 to S60:
s10, obtaining image information of an image to be displayed, wherein the image to be displayed comprises a plurality of image pixels, each image pixel corresponds to one second pixel, and different image pixels correspond to different second pixels. The image information of the image to be displayed includes the target brightness of each image pixel.
And S20, determining the initial brightness of each first pixel according to the target brightness of each image pixel.
For any first pixel, a plurality of second pixels corresponding to the first pixel may be determined first, and the initial brightness of the first pixel may be determined according to the maximum brightness of a plurality of image pixels corresponding to the plurality of second pixels.
And S30, performing brightness correction on at least part of the first pixels to obtain corrected brightness, wherein for each first pixel after the brightness correction, the corrected brightness is obtained according to the initial brightness of the first pixel and the initial brightness of a plurality of first pixels around the first pixel.
That is, when displaying an image, the brightness of the first pixel of the first panel is adaptively corrected according to the image to be displayed, so that the corrected brightness of the corrected first pixel is used as a transition value between the initial brightness and the initial brightness of the surrounding first pixels. For example, if the first pixel corresponding to a certain second pixel X2 is X1, and the first pixel corresponding to a second pixel Y2 adjacent to the second pixel X2 is Y1, and the initial luminance of the first pixel X1 is 200 and the initial luminance of the second pixel Y2 is 0, the corrected luminance of the second pixel Y2 is 100 after correction, so that even if the second pixel Y2 is shifted to correspond to the first pixel X1, the dark shadow generated at the first pixel X1 can be improved.
And S40, determining the backlight brightness which can be received by each second pixel according to the current brightness of each first pixel. The current brightness of the first pixel subjected to brightness correction is the corrected brightness; the current brightness of the first pixel without brightness correction is the initial brightness.
When the pixel position relationship of the first panel and the second panel is as shown in fig. 2, each second pixel may overlap with a plurality of first pixels, that is, the backlight of the second pixel is provided by the emergent light rays of the plurality of first pixels, and therefore, for any second pixel, the backlight brightness of the second pixel can be determined according to the brightness of the plurality of first pixels overlapped with the second pixel. The backlight luminance of the second pixel may be a weighted sum of current luminances of a plurality of first pixels capable of providing light to the second pixel.
And S50, determining the corrected brightness of each second pixel according to the backlight brightness of each second pixel and the target brightness of the corresponding image pixel.
The target brightness of the image pixel is determined by the brightness of the corresponding second pixel and the brightness of the first pixel, and a certain mapping relationship exists among the first pixel, the second pixel and the first pixel, so that after the backlight brightness of each second pixel and the target brightness of the corresponding image pixel are determined, the corrected brightness of the second pixel can be determined.
And S60, driving the first pixels to display according to the corrected brightness of each first pixel, and driving the second pixels to display according to the corrected brightness of the second pixels, so that the brightness of the light finally emitted by the second pixels reaches the target brightness of the corresponding image pixels.
In the embodiment of the present disclosure, after the target brightness of each image pixel in the image to be displayed is obtained, brightness correction is also performed on at least a part of the first pixels according to the image to be displayed, so that the corrected brightness of the corrected first pixels is used as a transition value between the initial brightness and the initial brightness of the surrounding first pixels. For example, if the first pixel corresponding to a certain second pixel X2 is X1, and the first pixel corresponding to a second pixel Y2 adjacent to the second pixel X2 is Y1, and the initial luminance of the first pixel X1 is 200 and the initial luminance of the second pixel Y2 is 0, the corrected luminance of the second pixel Y2 is 100 after correction, so that even if the second pixel Y2 is shifted to correspond to the first pixel X1, the dark shadow generated at the first pixel X1 can be improved.
Specifically, the driving method in the embodiment of the present disclosure is described below, and the driving method includes the following steps S10 to S60:
s10, obtaining image information of an image to be displayed, wherein the image to be displayed comprises image pixels corresponding to the second pixels one by one, and the image information of the image to be displayed comprises the target brightness of each image pixel.
Fig. 4 is a flowchart of an alternative implementation manner of step S10 provided in some embodiments of the present disclosure, and as shown in fig. 4, step S10 may include steps S11 to S15:
and S11, acquiring original image information of the image to be displayed, wherein the original image information comprises the resolution of the image to be displayed and the color information of each image pixel in the RGB space.
Wherein the color information of each image pixel in RGB space, i.e., the R value, G value, and B value of each image pixel in RGB space.
S12, judging whether the resolution of the image to be displayed is matched with the resolution of the first panel; if the fitting is performed, step S13 is performed, and if the fitting is not performed, steps S14 and S15 are performed.
Illustratively, the area of the first pixel is a times of a of the second pixel, the resolution of the image to be displayed is assumed to be p × q, the resolution of the first panel is assumed to be g × h, if p × g × a and q × h × a, the resolution of the image to be displayed is adapted to the resolution of the first panel, otherwise, the two are not adapted.
And S13, converting the color information of each image pixel in the original image information in the RGB space into HSV space to obtain the target brightness of each image pixel.
And S14, performing resolution conversion on the image to be displayed to obtain a converted image.
And S15, converting the color information of each image pixel in the converted original image information in the RGB space into the HSV space to obtain the target brightness of each image pixel.
Illustratively, the area of the first pixel is a × a times of the second pixel, and assuming that the resolution of the image to be displayed is p × q and the resolution of the second panel is g × h, p < g × a, q < h × a, then, when performing the resolution conversion, the image pixels of the first row and/or the last row of the image to be displayed may be supplemented with a number of rows of image pixels before the image pixels of the first row and/or the last row of the image to be displayed, and a number of columns of image pixels after the image pixels of the first row and/or the last row of the image to be displayed, so that the resolution of the supplemented image is adapted to the resolution of the first panel. The image pixels supplemented before the first row of image pixels can be the copy result of the first row of image pixels; the image pixels supplemented after the last line of image pixels may be the result of a copy of the last line of image pixels; similarly, the image pixel supplemented before the first column of image pixels may be the result of copying the first column of image pixels, and the image pixel supplemented after the last column of image pixels may be the result of copying the last column of image pixels.
And S20, determining the initial brightness of each first pixel according to the target brightness of each image pixel.
Fig. 5 is a schematic diagram illustrating how to obtain the initial brightness of each first pixel provided in some embodiments of the present disclosure, and as shown in fig. 5, in some embodiments, the initial brightness of each first pixel may be obtained according to the following steps S21 to S22.
And S21, acquiring the target brightness of a plurality of image pixels corresponding to the first pixel.
For example, the plurality of image pixels corresponding to the first pixel are image pixels corresponding to a plurality of second pixels overlapping with the first pixel when the alignment is correct.
S22, determining an initial brightness of the first pixel according to the target brightness of the plurality of image pixels corresponding to the first pixel.
Illustratively, the plurality of second pixels corresponding to each first pixel are arranged in n rows, n is an integer greater than 1, and for the case shown in fig. 2, n is 4. In this case, step S22 may specifically include steps S221 to S222:
step S221, for the second pixels in the ith row corresponding to the first pixel, determining a sampling value VLi of the second pixel in the ith row according to a maximum value Vmax _ i and a mean value Vmean _ i in the target luminances of the plurality of image pixels corresponding to the second pixels in the ith row and formula (3);
VLi＝K_Li*(Kvmax_i*nmax_i+(1-Kvmax_i)*nmean_i (3)
k _ Li is a sampling weight corresponding to the second pixel of the ith row; nmax _ i is Nvmax _ i and Vmax _ i is a first weighting coefficient corresponding to the second pixel in the ith row; nmean _ i ═ Nvmean _ i × Vmean _ i; the Nvmean _ i is a second weighting coefficient corresponding to the second pixel of the ith row; kvmax _ i is a third weighting coefficient corresponding to the second pixel on the ith row. i is a positive integer in the range of [1, n ].
The weighting coefficients and the sampling weights can be determined according to actual product requirements, and the first weighting coefficients corresponding to the second pixels in different rows can be the same or different; the second weighting coefficients corresponding to the second pixels in different rows may be the same or different; the third weighting coefficients corresponding to the second pixels in different rows can be the same or different; the sampling weights corresponding to the second pixels in different rows may be the same or different.
S222, taking a maximum value of sampling values of a plurality of rows of second pixels corresponding to the first pixel as an initial brightness of the first pixel, so as to ensure that each second pixel can receive enough backlight.
And S30, performing brightness correction on at least part of the first pixels to obtain corrected brightness, wherein for each first pixel with brightness correction completed, the corrected brightness is obtained according to the initial brightness of the first pixel and the plurality of first pixels around the first pixel.
In some embodiments, step S30 may specifically include: for each first pixel, a preset processing procedure is performed, and fig. 6 is a schematic diagram of a preset processing procedure of an mth first pixel provided in some embodiments of the present disclosure, where m is a positive integer less than or equal to the total number of the first pixels. As shown in fig. 6, the preset processing procedure of the mth first pixel includes:
s30, judging whether a bright line exists on the reference image; if yes, go to step S31, otherwise, go to step S32.
And S31, judging that the mth first pixel is in a to-be-transited area adjacent to the bright line, if so, adjusting the initial brightness of the mth first pixel according to the initial brightness of the first pixel corresponding to the bright line and the brightness of the background area of the reference image. If the mth first pixel is not in the region to be transitioned adjacent to the bright line, step S32 is performed (i.e., when there is no bright line in the reference image, or there is a bright line in the reference image but the mth first pixel is not in the region to be transitioned adjacent to the bright line, step S32 is performed).
Wherein the reference image is generated according to initial brightness of a plurality of first pixels of the first panel. The number and arrangement of the pixels in the reference image are the same as those of the first pixels in the first panel, and the brightness of the pixels in the reference image is the initial brightness of the first pixels at the corresponding positions. The case where there is a bright line on the reference image includes: the initial brightness of the first pixels of one or more continuous lines (for example, two lines or three lines) in the first panel is obviously greater than that of the first pixels at other positions; or, the initial brightness of a certain column or consecutive columns (for example, two columns or three columns) in the first panel is obviously greater than the brightness of the first pixel at other positions; of course, other situations are also possible, for example, the brightness of the first pixels arranged obliquely is obviously greater than that of the other first pixels.
The region to be transited can be regarded as a region which is adjacent to the bright line and has a preset width. In some examples, the width of the region to be transitioned is the width of three first pixels. For example, if the initial brightness of a certain column of first pixels in the first panel is significantly greater than the initial brightness of other columns of first pixels (i.e., there is a vertical bright line in the reference image), the region where the three columns of first pixels on the left and right sides of the bright line are located is used as the region to be transitioned. The background area of the reference image refers to the area of the reference image except for the bright lines and the area to be transited.
In step S31, when adjusting the initial brightness of the mth first pixel, the brightness of the mth first pixel may be adjusted to a transition value between the initial brightness of the first pixel unit corresponding to the bright line and the brightness of the background area, which is equivalent to expanding the bright line, so that when the alignment deviation occurs between the first panel and the second panel, the occurrence of the dark shadow may be reduced. Optionally, the width of the region to be transited is the width of three first pixels, that is, each side of the bright line is expanded by three pixels, so that the color shift problem generated when two panels are misaligned can be reduced.
In one example, the process of adjusting the initial brightness of the mth first pixel in step S31 may include: adjusting the initial brightness of the mth first pixel by using a preset expansion coefficient to obtain a first processing value; determining a first region centered on the mth first pixel, the first region including r x r first pixels; and filtering the first area by using a preset filter core of r to obtain a second processing value of the mth first pixel, and taking the maximum value of the first processing value and the second processing value as the corrected brightness of the mth first pixel.
Wherein, r elements in the filtering kernel correspond to r first pixels in the first region one by one; filtering the first region by using a preset filtering core of r, specifically: multiplying each element in the filtering kernel by the corresponding first pixel, thereby obtaining r x r products; then the r x r products are superimposed.
Wherein r is an odd number greater than 1. In some embodiments, in order to prevent the calculation amount from being too large while ensuring the display effect of the display module, r may be 5.
S32, determining a first region centered on the m-th first pixel, the first region including r × r first pixels. Wherein r can be 5.
S33, determining whether the initial luminance of the mth first pixel is the maximum value of the initial luminances of all the first pixels in the first area. If so, keeping the initial brightness of the mth first pixel unchanged; if not, go to step S34: and determining the corrected brightness of the mth first pixel at least according to the result of the first region after the first region is subjected to preset r x r filtering kernel filtering.
In some embodiments, step S34 may specifically include the following steps S341 to S343:
s341, determining a maximum initial brightness max33 in the mth first pixel and the plurality of first pixels immediately adjacent to the mth first pixel, and calculating a first filtered brightness filter33 of the mth first pixel according to the following formula (1):
filter33＝K*max33+(1-K)*tmp (1)
where K is an adaptive coefficient corresponding to the maximum initial luminance max 33.
The plurality of first pixels "immediately adjacent" to the mth first pixel are other first pixels that are in the same row as the mth first pixel and are adjacent to the mth first pixel; and other first pixels which are in the same column with the mth pixel and are adjacent to the mth first pixel. That is to say, when the mth first pixel is not located at the edge of the first panel, the plurality of first pixels immediately adjacent thereto are four adjacent first pixels, i.e., the upper, lower, left, right, and adjacent first pixels of the mth first pixel unit.
FIG. 7 is a graph of K versus max33 provided in some embodiments of the present disclosure. As shown in fig. 7, K is positively correlated with the maximum initial luminance max 3.
S342, filtering the first region by using a preset r × r filtering core, so as to obtain a second filtered brightness of the mth first pixel.
The process of filtering the first region by using the preset r × r filtering core is described above, and is not described herein again.
S343, judging whether the first filtering brightness filter33 is larger than a preset threshold value, if so, calculating the correction brightness subfilter of the mth pixel according to a formula (2), and if not, taking the second filtering brightness as the correction brightness of the mth pixel;
subfilter＝k33*filter33+(1-k33)*filter33 (2)
wherein k33 is a preset weight.
In one example, two image pixels a and B exist at a position where a light-dark change in an image to be displayed is obvious, wherein the brightness of the image pixel a is 255, and the brightness of the image pixel B is 0; the initial luminance of the first pixel a1 corresponding to the image pixel a is 255, and the initial luminance of the first pixel B1 corresponding to the image pixel B is 0. If the initial brightness of the first pixel B1 is not corrected, a dark shadow will appear at the second pixel A2 when the second pixel A2 corresponding to the image pixel A is misaligned over the first pixel B1. In the step S34, the second filtered luminance of the first pixel B1 is obtained to be smaller (because the second filtered luminance is equivalent to a weighted sum of luminances of r × r first pixels, and initial luminances of some first pixels in the r × r first pixels may be lower), for example, 100. If the second filtered luminance is directly taken as the modified luminance, a shadow may still occur once the second pixel a2 is misaligned over the first pixel B1. The first filtered luminance of the first pixel B1 is obtained according to the maximum initial luminance max33 of the plurality of first pixels that are immediately adjacent, and for the first pixel B1, max33 is 255, so the difference between the first filtered luminance and 255 is small. At this time, the difference between the corrected brightness obtained by weighted summation of the first filtered brightness and the second filtered brightness and 255 is small, even if the second pixel corresponding to the image pixel a is displaced above the first pixel B1, the brightness of the light finally emitted by the second pixel a2 is not much lower than 255, and the second filtered brightness also participates in the weighted calculation of the corrected brightness, so as to prevent the corrected brightness from being too high, and prevent the second pixel B2 corresponding to the image pixel B from appearing bright shadows when the alignment of the two panels is accurate.
That is, through the process of step S34, the display effect when the two panels are misaligned can be improved, and the display effect when the two panels are correctly aligned can be ensured.
It should be understood that, in the above embodiment, the preset processing procedure of the mth first pixel is taken as an example for explanation, and the above procedure may be adopted for other first pixels as well.
And S40, determining the backlight brightness which can be received by each second pixel according to the current brightness of each first pixel.
In some embodiments, step S40 may include:
for any one second pixel, all first pixels capable of providing light rays for the second pixel are marked as reference pixels under the condition that the maximum alignment deviation exists between the first panel and the second panel; and finally, carrying out weighted summation on the current brightness of all the reference pixels corresponding to the second pixel to obtain the backlight brightness of the second pixel.

In the case where the maximum misalignment occurs between the first panel and the second panel, taking the second pixels a-d in fig. 8 as an example, the backlights received by the second pixels a and b are provided by the first pixels S _22, S _23, S _32, and S _33, and the backlights received by the second pixels c and d are provided by the first pixels S _23, S _24, S _33, and S _ 34. The backlight brightness of the second pixels a, b, c, d is denoted as subbl (a), subbl (b), subbl (c), subbl (d), respectively, and:
SubBL(a)＝a1*S_22+a2*S_23+a3*S_32+a4*S_33
SubBL(c)＝c1*S_22+c2*S_23+c3*S_32+c4*S_33
SubBL(b)＝b1*S_23+b2*S_24+b3*S_33+b4*S_34
SubBL(d)＝d1*S_23+d2*S_24+d3*S_33+d4*S_34
wherein a 1-a 4, b 1-b 4, c 1-c 4 and d 1-d 4 are all preset weighted values.
In the embodiment of the present disclosure, when determining the backlight brightness of the second pixel, the calculation is performed based on the situation when the maximum misalignment occurs in the two panels, and various misalignment situations are considered, so that the backlight brightness actually received by the second pixel under the misalignment situation is obtained more accurately.
And S50, determining the corrected brightness of each second pixel according to the backlight brightness of each second pixel and the target brightness of the corresponding image pixel.
The target brightness of the image pixel is equal to or approximately equal to the product of the corrected brightness of the second pixel and the backlight brightness, so that the corrected brightness of the second pixel can be determined according to the backlight brightness of each second pixel and the target brightness of the corresponding image pixel.
In some embodiments, the modified luminance of the second pixel is determined according to the following formula:
wherein V is the target brightness of the image pixel; subBL is the backlight brightness of the second pixel, and Mainari is the corrected brightness of the second pixel. γ 0 is 2.2, γ 1 is 1, and γ 2 is 2.2.
And S60, driving the first pixels to display according to the corrected brightness of each first pixel, and driving the second pixels to display according to the corrected brightness of the second pixels, so that the brightness of the light finally emitted by the second pixels reaches the target brightness of the corresponding image pixels.
Wherein the second pixel comprises three sub-pixels of red, green and blue, and in some embodiments, the brightness of each sub-pixel in the second pixel is determined according to the following formula;
MainOri(R,G,B)＝MainOri*((1/V)*2^18)*Input(R,G,B)/2^18
where MainOri (R, G, B) is the luminance of the red, green and blue sub-pixels in the second pixel, respectively, and Input (R, G, B) is the red, green and blue components of the image pixel in RGB space, respectively.
The foregoing is a description of the driving method in the embodiment of the present disclosure, and it can be seen that the driving method in the embodiment of the present disclosure can adaptively adjust the brightness of the first panel and the second panel according to the content of the image to be displayed, so as to improve the problem of bright and dark shadows generated when the two panels are misaligned; and the deviation amount and the deviation direction of the two panels do not need to be determined in the adjusting process. And when the backlight brightness of the second pixel is determined, the calculation is carried out based on the situation when the maximum alignment deviation occurs on the two panels, and various dislocation situations are considered, so that the backlight brightness actually received by the second pixel under the condition of dislocation is obtained more accurately, the accuracy of the corrected brightness of the second pixel is improved, and the display effect is ensured.
