To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived from the description of the embodiments of the disclosure by a person skilled in the art, are intended to be within the scope of the disclosure.
The backlight source used by the display in the related art is the whole area light source, when the brightness is adjusted, the whole picture can become bright or dark at the same time, and the Local Dimming uses the backlight composed of hundreds of LEDs to replace the backlight in the related art. By designing a corresponding algorithm, the backlight LED can be adjusted according to the brightness of the image, so that the contrast of the image is improved, and the energy consumption can be reduced.
With the continuous progress of the process, the size of the LED device is smaller and smaller, the quantity of dynamic subareas of a screen backlight source formed by the LED device is also greater, and the local Dimming device in the related art is limited by too small number of subareas, so that the halo phenomenon is not additionally processed, or the contrast ratio is reduced by only increasing the backlight in a dark area, so that the halo phenomenon exists in a display picture, and the problem of pixel compensation overflow occurs, which causes some detailed information to be lost, and reduces the picture display effect. For the Local Dimming display device with high subarea, which is composed of small-sized LEDs and dynamic backlight, the technical advantages should be fully exerted, and the display effect is further improved.
Currently, the basic area backlight adjustment algorithm mainly includes three parts: calculation of backlight brightness, actual backlight simulation and liquid crystal pixel compensation. The research shows that the algorithm in the related art mainly focuses on reducing the energy consumption of the backlight source, and a particular method focuses on improving the contrast of the final display image, but for the display equipment of the LED backlight source with smaller size, the quantity of the subareas is higher, the backlight area of the whole picture is divided more finely, the displayed brightness and contrast are excellent, but an obvious halo, namely a halo phenomenon, exists at the light and dark boundary of the picture due to the light leakage of the liquid crystal. Meanwhile, since local Dimming itself is that different pixels in the same subarea correspond to the same backlight value, the problem of compensation overflow can be caused inevitably in pixel compensation based on backlight brightness, so that some detail information is lost, and the viewing effect is influenced.
Please refer to
Step 11: for each of the backlight subareas, calculating an initial backlight value of the backlight subarea according to pixel information of the display subarea corresponding to the backlight subarea.
In this step, since one display subarea corresponds to one backlight subarea, the initial backlight value of the backlight subarea corresponding to the pixel information in each display subarea can be calculated by obtaining the pixel information in each display subarea. In some embodiments, each pixel may include a plurality of sub-pixels, such as R, G, B sub-pixels, a maximum of the brightness values of the plurality of sub-pixels representing the brightness value of the pixel, and the pixel information within the display subarea includes an average of the brightness values of all the pixels within the display subarea. In the embodiment of the present disclosure, an average value method is adopted, that is, an average value of brightness values of all pixels in a display subarea is used as an initial backlight value of a corresponding backlight subarea.
Step 12: determining a first correction backlight value of the backlight subarea according to a preset backlight threshold and an initial backlight value of each of the other backlight subareas adjacent to the backlight subarea.
In the embodiment of the present disclosure, step 11 and step 12 are performed for each backlight subarea, and the backlight subarea in which step 11 and step 12 are being performed may be referred to as a current backlight subarea.
The halo phenomenon is mainly expressed in that a circle of obvious halo appears in an area which is supposed to be dark around a highlight image, and based on the characteristic of high subarea of an LED backlight source, the most effective method is to weaken the backlight brightness of a peripheral halo highlight area or an isolated dotted line-shaped highlight halo area without interfering with an area without the halo phenomenon. However, in practical tests, it is found that not all halo subareas are suitable for suppression, for example, after the edge of a large area of pure color highlight subarea is subjected to halo suppression to reduce the backlight brightness, an obvious edge darkening phenomenon occurs, and the visual effect is adversely affected. Therefore, in the embodiment of the present disclosure, a preset backlight threshold is set, and then the initial backlight value of each backlight subarea is corrected according to the preset backlight threshold and the initial backlight value of the backlight subarea adjacent to each backlight subarea, so as to obtain a first correction backlight value corresponding to each backlight subarea. The isolated backlight subareas which are judged to be easy to generate the halo phenomenon can be greatly inhibited, the non-isolated backlight subareas cannot be processed, and the original backlight data can still be kept, so that the halo phenomenon is reduced to the maximum extent, and the optimal display effect is kept.
In an embodiment of the disclosure, the preset backlight threshold includes a first preset backlight threshold and a second preset backlight threshold, and the determining the first correction backlight value of the backlight subarea according to the preset backlight threshold and the initial backlight value of another backlight subarea adjacent to the backlight subarea includes:
Specifically, when halo suppression is performed, first, two judgment thresholds, namely a first preset backlight threshold and a second preset backlight threshold, are set, and then, for a current backlight subarea, a backlight value of a backlight subarea adjacent to the current backlight subarea, that is, an initial backlight value of a backlight subarea adjacent to a target backlight subarea, is obtained. Generally, since the backlight subareas are distributed in an array, the quantity of the backlight subareas adjacent to the target backlight subarea is eight, the quantity of the initial backlight values in the eight adjacent backlight subareas which are greater than the second preset backlight threshold is recorded, and according to the quantity, the type of the target backlight subarea, namely, the type of the target backlight subarea belongs to the isolated halo backlight subarea or the non-isolated halo backlight subarea can be determined. The isolated halo backlight subareas are isolated backlight subareas which are easy to generate a halo phenomenon; the non-isolated halo backlight subareas are backlight subareas which are easy to generate halo phenomena but belong to the edges of large-area highlight areas instead of being isolated. Therefore, different correction processing modes are carried out on the initial backlight value of the target backlight subarea according to the type of the target backlight subarea to obtain the first correction backlight value of the current backlight subarea, and the problem of display effect reduction caused by large-amplitude suppression on all backlight subareas is solved.
In this embodiment of the disclosure, the determining the first correction backlight value of the backlight subarea, according to the first preset backlight threshold, the quantity, the type of the backlight subarea and the initial backlight values of a plurality of the backlight subareas adjacent to the backlight subarea includes:
That is, after the type of the current backlight subarea is determined, the value obtained by k in the above formula is determined, and the value falls within the range of 0 to 1, so that the first correction backlight value of the current backlight subarea can be calculated by substituting different values of k into the formula.
Referring to
In the embodiment of the present disclosure, k is a backlight compression coefficient, the smaller the value is, the darker the compressed backlight is, and the larger the value is, the brighter the compressed backlight is. In an alternative embodiment, according to the experimental test result, the value of k is selected as follows:
num is the quantity of the initial backlight values in the eight backlight subareas adjacent to the backlight subarea which are larger than a second preset backlight threshold.
That is to say, when num is less than 3, if the current backlight subarea is judged to be an isolated backlight subarea which is easy to generate the halo phenomenon, k is greatly compressed by taking a smaller numerical value (0.3) to reduce the halo phenomenon; when num is more than or equal to 3, judging that the current backlight subarea is a backlight subarea which is easy to generate a halo phenomenon, but belongs to the edge of a large-area highlight area and is not suitable for large-amplitude compression processing, and taking a larger numerical value (0.8) for k, so that the halo phenomenon is slightly reduced and the problem of too dark edge is avoided; when the value selection mode is adopted for value taking, a better correction effect can be obtained.
The first preset backlight threshold, that is, the backlight compression algorithm trigger threshold, takes a magnitude relationship between the first preset backlight threshold and the initial backlight value of the backlight subarea adjacent to the backlight subarea as a segmentation condition of the formula (which may be regarded as a segmentation function), so that under the condition of Lmin≥th1 or Lmin≥Lavg, the initial backlight value of the backlight subarea is taken as the first correction backlight value of the backlight subarea, that is, the backlight subarea is not prone to halo, and then compression suppression processing is not performed on the initial backlight value of the backlight subarea, and the original backlight data is maintained, so as to maintain the optimal display effect. Under the condition of Lmin<th1 and Lmin<Lavg, the initial backlight value of the backlight subarea is corrected by adopting the formula, namely the backlight subarea is a backlight subarea which is easy to generate a halo phenomenon, and the value of k is further determined according to the type of the backlight subarea to inhibit the backlight subarea, so that the halo phenomenon is reduced to the maximum extent. Here, each backlight subarea of the backlight element is corrected through the above formula, and the first correction backlight values of all backlight subareas can be obtained, thereby achieving the reduction of the halo phenomenon to the maximum extent and simultaneously maintaining the best display effect.
In an optional embodiment, the value range of the first preset backlight threshold is 0-255, and through experimental tests, a better correction display effect can be obtained when the value is 128. The value range of the second preset backlight threshold is 128-255, and through experimental tests, a better correction display effect can be obtained when the value is 200.
In the embodiment of the present disclosure, the backlight adjusting method further includes:
In the working process of the display device, most of the displayed pictures are dynamic images and videos, so the backlight numerical values of all backlight subareas are changed in real time along with the change of picture contents, which results in that the same backlight subarea may belong to the backlight subarea in which the halo phenomenon occurs when the previous frame of image is displayed, and does not belong to the backlight subarea in which the halo phenomenon occurs when the next frame of image is displayed, so the numerical values obtained after the change between the two frames is processed by an algorithm are relatively different, the backlight numerical values are greatly jumped, and finally the flicker phenomenon is generated, which is also a negative effect brought by the halo suppression. Therefore, it is necessary to perform flicker suppression processing on the first correction backlight value to obtain a second correction backlight value, and then perform backlight driving on the target backlight subarea according to the second correction backlight value.
In this embodiment of the disclosure, the performing the flicker suppression processing on the first correction backlight value to obtain the second correction backlight value of the backlight subarea includes:
That is to say, the second correction backlight value of the backlight subarea when the current frame image is displayed is weighted and summed through the second correction backlight value of the backlight subarea when the previous frame image is displayed and the first correction backlight value of the backlight subarea when the current frame image is displayed, so as to balance the backlight values of the upper and lower frames and prevent large-amplitude change. The coefficient of m is 0-1, if the value of m is large, a backlight delay feeling can be generated, if the value of m is too small, the effect of flicker suppression cannot be achieved, and through practical tests, a good flicker suppression effect can be obtained when the value of m is 0.65. And finally, driving the backlight component to correspondingly emit light according to the second correction backlight values of all the backlight subareas.
In the embodiment of the present disclosure, the backlight adjusting method further includes:
In some embodiments, the pixel value may be a brightness value of the pixel.
In the related art, no special processing is performed specifically for the compensation overflow area, and in order to make the finally displayed image satisfy the gamma curve, the original image pixel information of each pixel in each display subarea needs to be calculated according to the backlight value of the corresponding backlight subarea, so as to obtain the pixel value under the corresponding backlight value. Because the pixels of the same display subarea correspond to the backlight numerical values of a single backlight subarea, an overflow truncation phenomenon occurs after part of pixels are subjected to calculation processing, and the details of a displayed image are lost, and the phenomenon generally exists in local Dimming equipment. Therefore, in order to ensure the display effect of the display device, pixels for compensating overflow need to be suppressed so as to keep more image detail information as much as possible.
Specifically, firstly, the maximum pixel value of all the pixels in each display subarea is counted, and then the backlight value when all the pixels in the display subarea are compensated and overflow does not happen right, that is, the minimum backlight threshold, is reversely deduced according to the maximum pixel value of each display subarea and a preset gamma curve, and can be specifically calculated by adopting the following formula:
in the formula, Vmax is the maximum pixel value in all pixels in the display subarea, Lmax is the maximum backlight value that can be reached by the corresponding backlight subarea are usually 255, Lth is the minimum backlight threshold at which no overflow occurs when all pixels in the display subarea are compensated, and 2.2 in the formula is the gamma value corresponding to the preset gamma curve, and the value also changes correspondingly according to different preset gamma curves, for example, the value may also be 2.0.
When the above formula is actually applied to calculation, since the quantity of pixels in one display subarea is large, the value of Vmax can be properly reduced, and the value of Lmax can be properly increased, and it is not necessary to consider the situation that each pixel does not generate compensation overflow.
In this embodiment of the disclosure, the calculating the backlight compensation value of each backlight subarea according to the first correction backlight value of each backlight subarea and the minimum backlight threshold corresponding to each backlight subarea to obtain the backlight compensation matrix corresponding to all the backlight subareas includes:
Specifically, an initial backlight compensation matrix with all zero initial values may be constructed, and then, for each backlight subarea, the first correction backlight value of the backlight subarea is compared with the minimum backlight threshold corresponding to the backlight subarea, if the first correction backlight value of the backlight subarea is smaller than the minimum backlight threshold, it means that overflow occurs during pixel compensation of the display subarea corresponding to the backlight subarea, and therefore, a difference between the first correction backlight value of the backlight subarea and the minimum backlight threshold corresponding to the backlight subarea needs to be calculated, where the difference is a corresponding backlight compensation value, and the difference is recorded in a corresponding position of the initial backlight compensation matrix to replace the original value (i.e., zero is replaced). And executing the steps for each backlight subarea, thereby obtaining a backlight compensation matrix formed by the backlight compensation values corresponding to all the backlight subareas.
Referring to
In an embodiment of the disclosure, he compensating the pixels of the display subarea corresponding to each backlight subarea according to the backlight compensation matrix and the second correction backlight value of each backlight subarea includes:
Specifically, after a backlight compensation matrix formed by the backlight compensation values of all the backlight subareas is obtained, the backlight compensation matrix is superposed with the second correction backlight value of each backlight subarea when the current frame picture is displayed, that is, the second correction backlight value of each backlight subarea is superposed with the corresponding backlight compensation value in the backlight compensation matrix to obtain a backlight numerical value matrix corresponding to all the backlight subareas; then, according to the backlight numerical value matrix, the pixel compensation value of the display subarea corresponding to each backlight subarea can be determined, and finally, the pixel of each display subarea is compensated.
In an embodiment of the present disclosure, the determining the pixel compensation value of each display subarea according to the backlight numerical value matrix includes:
The method includes the steps of firstly, performing convolution calculation on a Point Spread Function (PSF) obtained by actually measuring a backlight light source used in a backlight subarea and a backlight numerical value matrix to obtain smooth backlight brightness information consistent with the resolution of an original input image, namely obtaining the backlight brightness information corresponding to each image pixel point in each display subarea, and performing corresponding compensation on pixels of an original image according to the backlight brightness information, so that better display effect can be obtained by matching the output backlight brightness. The pixel compensation can be calculated using the following formula:
BLfull is the brightness of the backlight subarea when being fully bright generally corresponds to 255, and BLi,j′ is a backlight brightness value obtained after convolution calculation, and Yi,j and Yi,j′ are a pixel values before compensation and a pixel value after compensation respectively.
Please refer to
The halo problem is mainly due to the light leakage characteristics of the liquid crystal, most pronounced in the side view case, which is slightly less visible than the side view but also has been shown to affect the viewing experience. The halo area is reduced on a high backlight zone (i.e., a higher number of backlight zones) local dimming device compared to a low zone device but still significant. After the backlight adjusting method is adopted for adjustment, the halo problem is basically solved within 30 degrees of a front view angle, and the halo phenomenon is greatly reduced although the halo problem cannot be completely eliminated under the side view condition of more than 30 degrees. Meanwhile, for the compensation overflow problem commonly existing in the local dimming algorithm, the embodiment of the disclosure effectively inhibits the overflow problem, and further improves the display effect.
By adopting the backlight adjusting method, the high contrast effect of Local Dimming can be realized, and meanwhile, compared with a Local Dimming algorithm in the related technology, the problems of halo phenomenon and detail loss caused by compensation overflow are greatly inhibited, the advantage of high backlight subarea number is exerted, and the viewing effect is greatly improved.
In a word, according to the backlight adjusting method of the embodiment of the disclosure, under the condition that the overall display brightness and contrast are not affected, the halo problem of the local dimming device and the local detail loss problem caused by compensation overflow can be well weakened, and the picture effect is improved.

If the quantity of device backlight subareas is sufficiently high, for example, a 75 inch 10000 subareaed display panel has substantially no significant backlight flicker after using a halo suppression module compared to a 75 inch 5000 subareaed display panel, and thus, the backlight flicker suppression module 73 may be masked and have fewer pixel overflow subareas. Theoretically, if the quantity of backlight subareas is large enough and the area of a single backlight subarea is small enough, the pixel overflow problem can be avoided, and the overflow compensation suppression module 74 can be shielded.
