Detailed Description
A detailed description will be given below of a display device and a method for adjusting luminance thereof according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for adjusting brightness of a display device, as shown in fig. 1, the method may include:
s101, acquiring a display picture of a current frame;
for obtaining the display image of the current frame, the obtaining manner may be any manner known to those skilled in the art that can obtain the display image, and is not limited herein.
S102, determining pictures in the current frame, which need to be displayed by a plurality of sub-regions; wherein the plurality of sub-regions are: dividing a display area in the display equipment in advance to obtain the display area;
when the display area is divided, the number of the divided sub-areas can be set according to actual needs so as to meet the needs of different application scenes and improve the flexibility of design. For example, but not limited to, 240 × 135 sub-regions are divided.
Meanwhile, when the display area is divided, the more sub-areas are divided, the more accurate the adjustment is, the lower the adverse effect on the non-still picture is, and therefore, in an actual situation, the display area can be subdivided to different degrees according to the actual situation.
In addition, the area of each divided sub-region can be set to be the same or different, and the design can be performed according to the actual situation, so that the requirements of different application scenes are met, and the design flexibility is improved.
S103, adjusting the brightness of the sub-area display picture meeting the preset brightness processing condition.
It should be noted that, for the sub-area display screen that does not satisfy the preset brightness processing condition, the brightness of the display screen can be maintained.
Therefore, the problem of screen burning caused by the fact that the display equipment displays the sub-area display picture meeting the preset brightness processing condition for a long time is solved, the display equipment in the embodiment of the invention has the screen burning prevention function, the display effect of the display equipment is improved, meanwhile, the problem of early aging of an O L ED material can be avoided, the service life of the O L ED material is prolonged, and the reliability of the display equipment is improved.
The steps S101 and S102 may be implemented by a Motion estimation and Motion Compensation module (MEMC) technology, and the step S103 is further combined to adjust the brightness of the sub-region display picture meeting the preset brightness processing condition, so that the method for adjusting the brightness of the display device in the embodiment of the present invention is implemented based on the MEMC technology, and the display device in the embodiment of the present invention also has a burn-in prevention function based on the MEMC technology.
In practical implementation, in the embodiment of the present invention, the brightness processing conditions are:
the method comprises the steps that first display content exists in continuous N frames of display pictures acquired in a first time, and N is not less than a first preset value and is greater than zero;
wherein the first time is: from the first moment to the moment when the display picture of the current frame is acquired, the first moment is as follows: the time when the display screen having the first display content is acquired for the first time.
The first display content may be understood as: the still picture in the continuous multi-frame display screen is not limited to, for example, a station caption, a subtitle, a display icon, and the like.
In addition, taking the first display content as the station caption as an example, after the display area is divided, the following situations may occur:
the splicing of the plurality of sub-areas can form a complete station caption, namely, one station caption is divided into a plurality of parts, and each part is respectively positioned in different sub-areas;
alternatively, a complete station caption is located in one sub-area, that is, only one sub-area has the station caption, and the other sub-areas have no station caption.
Of course, in any case, the brightness of the sub-area having the first display content may be adjusted by the method provided by the embodiment of the present invention, so that both cases are applicable to the scope of the present invention.
It should be noted that the setting of the first preset value is not specifically limited, and may be set according to the actual requirements of the user, so as to improve the flexibility of the design.
For example, a station caption with CCTV-1 as the first display content, a news simulcast played by the display device, and a second preset value of 10 are taken as examples for explanation.
The news simulcast starts to be played at the 7-point CCTV-1, so the time when the display picture of the first frame of news simulcast is acquired can be defined as a first time, and from this time, when the display picture of one frame of news simulcast is received, the content required to be displayed by each sub-area needs to be determined.
Taking one of the sub-regions displaying the first display content as an example, the sub-region may be marked as a sub-region w, when it is determined that the sub-region w displays the first display content in the currently received display picture, a counter +1 corresponding to the internally preset sub-region w is controlled, and then, whether the value of the current counter is not less than 10 is determined;
if not, the sub-region w does not meet the brightness processing condition, the display picture of the news simulcast is continuously received, and the numerical value of the counter is updated and the judgment is continuously carried out;
if yes, it indicates that the sub-region w has satisfied the brightness processing condition, and at this time, the subsequent brightness adjustment process may be performed on the sub-region w.
In this way, only the display brightness of the sub-area having the first display content in the continuous multi-frame display picture is adjusted, but the brightness of the sub-area not meeting the brightness processing condition is not adjusted, so that unnecessary operation can be reduced, the calculation amount of the processor is reduced, the power consumption of the processor is reduced, and the function of preventing screen burn-in can be realized.
Specifically, in the embodiment of the present invention, a method for determining a sub-area having first display content in each of the acquired consecutive N frames of display images may specifically be:
calculating the similarity between the pictures in any two continuous frames in the continuous N frames of display pictures required to be displayed by each sub-region to obtain N-1 similarity results corresponding to each sub-region;
accumulating the N-1 similarity results corresponding to each sub-region to obtain a reference result corresponding to each sub-region;
and determining the sub-area with the reference result larger than the second preset value as the sub-area with the first display content in the acquired continuous N frames of display images.
For example, taking three consecutive frames of display pictures, which are divided into two sub-regions, where the two sub-regions can be respectively labeled as sub-region a and sub-region B, then:
for subregion a:
calculating the similarity between the picture in the first frame to be displayed and the picture in the second frame to be displayed, and recording the calculation result as the similarity A1;
calculating the similarity between the picture in the second frame to be displayed and the picture in the third frame to be displayed, and recording the calculation result as the similarity A2;
accumulating the similarity A1 and the similarity A2 to obtain a reference result, and marking as Ac;
and if the Ac is larger than the second preset value, determining that the sub-area A can display the first display content in the continuous three-frame display picture.
For sub-region B:
calculating the similarity between the picture in the first frame to be displayed and the picture in the second frame to be displayed, and recording the calculation result as the similarity B1;
calculating the similarity between the picture in the second frame to be displayed and the picture in the third frame to be displayed, and recording the calculation result as the similarity B2;
accumulating the similarity B1 and the similarity B2 to obtain a reference result which is marked as Bc;
and if the Bc is smaller than the second preset value, determining that the sub-region B does not display the first display content in the three continuous frame display pictures.
When calculating the similarity, the calculation may be performed according to a local feature algorithm, or may be performed according to other algorithms, as long as the similarity can be calculated, and the specific calculation method is not limited herein.
It should be noted that the setting of the second preset value is not specifically limited, and the setting may be performed according to the actual requirements of the user, so as to improve the flexibility of the design.
Therefore, the sub-area with the first display content can be determined through a simple method, so that the brightness of a sub-area display picture with the first display content can be adjusted subsequently, the problem of screen burning caused by the fact that the display equipment displays the first display content for a long time is solved, and the display effect of the display equipment is improved.
In specific implementation, in the embodiment of the present invention, adjusting the brightness of the sub-area display screen that meets the preset brightness processing condition specifically includes:
and reducing the brightness of the sub-area display picture meeting the preset brightness processing condition.
For example, referring to fig. 2, when OCN ORIGINA L displayed in the upper left corner of the display device is determined as the first display content, only the brightness of the sub-region where OCN ORIGINA L is located is reduced, and no adjustment is required for the brightness at other positions, as shown from the left diagram to the right diagram, where the left diagram is the case before the brightness adjustment for the sub-region where OCN ORIGINA L is located, and the right diagram is the case after the brightness adjustment for the sub-region where OCN ORIGINA L is located.
Therefore, the problem of screen burning when the display equipment displays the first display content for a long time can be solved by adjusting the brightness of the display picture of the sub area with the first display content, so that the display effect of the display equipment is improved, and the user experience is improved.
Alternatively, if the luminance of the sub-region having the first display content is to be reduced, the luminance of the display frame is determined by the gray scale of the pixel in the display region, and when the pixel includes the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B, the luminance can be adjusted by adjusting the gray scale of the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B in the corresponding sub-region.
Specifically, the adjustment degree of the brightness of the display screen having the sub-area of the first display content may be adjusted according to actual conditions, and is not limited herein. For example, but not limited to, if it is determined by a pre-simulation calculation that when the luminance is lower than a certain threshold value, the burn-in phenomenon does not occur even if a certain still content is displayed for a long time, in this case, the threshold value may be set as a target value for the luminance adjustment.
In specific implementation, in the embodiment of the present invention, after determining the picture in the current frame that needs to be displayed by the plurality of sub-regions, and before adjusting the brightness of the sub-region display picture that meets the preset brightness processing condition, the method further includes: marking the sub-regions meeting the preset brightness processing conditions according to a preset algorithm;
adjusting the brightness of the sub-area display picture meeting the preset brightness processing condition specifically comprises: and adjusting the brightness of the display picture of the marked sub-area.
When the sub-region is marked, the sub-region may be marked by using a number, a symbol, a letter, or the like, which is not limited herein.
For example, but not limiting of, the sub-area for displaying the first display content is labeled 1, and the sub-area for displaying the dynamic content (i.e., the content displayed in the continuous multi-frame display may be different) is labeled 0.
Therefore, by the simple mode, the sub-area with the first display content and the sub-area without the first display content can be distinguished, so that the brightness adjustment can be performed in a targeted manner, the accuracy of the brightness adjustment is improved, adverse effects on other sub-areas are avoided, and misoperation is avoided.
The following describes a method for adjusting the signal according to an embodiment of the present invention with specific examples.
The first embodiment is as follows: the first display content is taken as a station caption for explanation, and is shown in fig. 3.
S301, acquiring a display frame of a frame;
s302, when the fact that the frame display picture has the station marks is determined, determining pictures needing to be displayed in all the sub-regions according to a preset sub-region division rule;
s303, marking the subarea with the station caption as 1, and marking the subarea without the station caption as 0;
s304, the value of a counter corresponding to the sub-area marked as 1 is plus 1;
s305, judging whether the numerical value of the current counter is not less than a second preset value; if yes, executing step S306, otherwise, executing step S307;
s306, reducing the brightness of the sub-area display picture marked as 1, and keeping the brightness of the sub-area display picture marked as 0;
s307, the brightness of the display picture of the current frame is kept.
