Referring to fig. 1 to 3, a display method according to an embodiment of the present disclosure includes the following steps:
011: when the display brightness is smaller than a preset brightness threshold value, acquiring display parameters of a display image;
012: determining a region to be corrected according to the display parameters;
013: adjusting the display parameters of the area to be corrected according to the preset parameter threshold value so that the display parameters of the area to be corrected are larger than or equal to the preset parameter threshold value; and
014: and displaying the adjusted display image.
The display device 10 of the embodiment of the present application includes an acquisition module 11, a determination module 12, an adjustment module 13, and a display module 14. The obtaining module 11, the determining module 12, the adjusting module 13 and the displaying module 14 are configured to perform step 011, step 012, step 013 and step 014, respectively. That is, the obtaining module 11 is configured to obtain a display parameter of the display image when the display brightness is smaller than a preset brightness threshold; the determining module 12 is configured to determine a region to be corrected according to the display parameter; the adjusting module 13 is configured to adjust a display parameter of the to-be-corrected region according to a preset parameter threshold, so that the display parameter of the to-be-corrected region is greater than or equal to the preset parameter threshold; the display module 14 is used for displaying the adjusted display image.
In some embodiments, the terminal 100 further includes a processor 20 and a display 30. The processor 20 is configured to obtain a display parameter of the display image when the display brightness is smaller than a preset brightness threshold; determining a region to be corrected according to the display parameters; adjusting the display parameters of the area to be corrected according to the preset parameter threshold value so that the display parameters of the area to be corrected are larger than or equal to the preset parameter threshold value; the display 30 is used to display the adjusted display image. That is, step 011, step 012, and step 013 can be implemented by processor 20, and step 014 can be implemented by display 30.
Specifically, the terminal 100 may be a mobile phone, a tablet computer, a display device, a notebook computer, a teller machine, a gate, a smart watch, a head-up display device, a game machine, and the like. As shown in fig. 3, the embodiment of the present application is described by taking the terminal 100 as an example, and it is understood that the specific form of the terminal 100 is not limited to a mobile phone.
In the OLED display screen, when the display brightness is low, the brightness of a black area or a green area (determined according to the structural design of different colors of the OLED, for example, when the current OLED displays black and green, the brightness of the black area or the green area is low, and the black area or the green area is prone to smear) in a display image is lower than that of a white area, and a diode of a pixel in the black area or the green area is in a reverse bias state.
Based on this, when the display brightness is lower than the preset brightness threshold, the display parameters of the display image are acquired. The preset luminance threshold is an empirical value, and the preset luminance threshold is different according to software parameters and hardware parameters of different displays 30, and the display parameters may be gray values, chrominance parameters, and the like.
It can be understood that the display image includes various regions with different colors, and the region to be corrected can be adjusted in a targeted manner, for example, the region to be corrected is a black region and a green region, and the phenomenon of smearing of the region to be corrected is prevented without affecting the display effect of the part of the display image which is not the region to be corrected.
The processor 20 is able to determine the area to be corrected based on the display parameters. When determining the region to be corrected, the processor 20 may first determine, according to the gray value, a pixel with a gray value of 0, where the pixel with the gray value of 0 is a black pixel, and then the processor 20 further determines, according to the chromaticity parameter of each pixel, the black pixel and the green pixel, and further determines the region where the black pixel and the green pixel are located, so as to serve as the region to be corrected.
After determining the area to be corrected, the processor 20 may correct the area to be corrected of the display image. The processor 20 may adjust the display parameter of the region to be corrected according to the preset parameter threshold, so that the display parameter of the region to be corrected is greater than or equal to the preset parameter threshold (e.g., adjust the gray value of the region to be corrected to be greater than or equal to the preset gray value threshold). It can be understood that the preset parameter threshold may be determined according to the display brightness of the pixel when the pixel is in the reverse bias state to the forward bias state from the diode reverse bias state, so as to ensure that the diode of the pixel in the region to be corrected is in the forward bias state after the display parameter of the region to be corrected is adjusted to be greater than or equal to the preset parameter threshold and displayed. When the user slides the display image, the color of the region to be corrected changes, and at this time, the display 30 can quickly respond and quickly adjust the color of the display region corresponding to the region to be corrected, so that the phenomenon of smearing of the display region corresponding to the region to be corrected when the user slides or the display image changes is prevented.
According to the display method, the display device 10 and the terminal 100 in the embodiment of the application, when the display brightness is low and the smear phenomenon is easy to occur, the region to be corrected is determined through the display parameters of the display image, and then the region to be corrected is adjusted and displayed according to the preset parameter threshold, so that the display parameters of the region to be corrected, in which the smear is easy to occur, in the display image are greater than or equal to the preset parameter threshold, and the diodes corresponding to the region to be corrected are all in the forward bias state, so that the smear phenomenon is prevented from occurring, and the display effect is good.
Referring to fig. 2, 3 and 4, in some embodiments, the display parameter includes a gray value, the predetermined parameter threshold includes a predetermined gray value threshold, and the step 012 includes the following steps:
0121: determining the image coordinates of the pixels to be corrected with the gray value smaller than a preset gray value threshold; and
0122: and determining the area to be corrected according to the image coordinates.
In certain embodiments, the determining module 12 is further configured to perform step 0121 and step 0122. That is, the determining module 12 is further configured to determine the image coordinates of the pixel to be corrected, where the gray value is smaller than the predetermined gray value threshold; and determining the area to be corrected according to the image coordinates.
In some embodiments, the processor 20 is further configured to determine image coordinates of the pixel to be corrected having a gray value less than a predetermined gray value threshold; and determining the area to be corrected according to the image coordinates. That is, steps 0121 and 0122 may be implemented by the processor 20.
In particular, the display parameters may include gray scale values, each pixel may correspond to a gray scale value, which may determine whether a pixel is a black pixel. The processor 20 may obtain image coordinates of pixels to be corrected whose gray values are smaller than a predetermined gray value threshold (e.g., 1, 2, 3, etc.), and then determine a region to be corrected in the display image according to the image coordinates of the pixels to be corrected, where the region to be corrected is a region where the pixels to be corrected are located.
It is understood that the display image may include pixels of different colors, and sometimes the black pixels do not form a black region, or the formed black region is small, and in this case, even though the black region may generate a smear, the display effect is also small. Therefore, the processor may combine two pixels to be corrected with a distance smaller than a preset distance (e.g., 1 pixel, 2 pixels, etc.) to be used as pixels in the same image area, so as to identify one or more image areas in the displayed image, and then the processor 20 may determine whether the number of pixels to be corrected in each image area is greater than a preset number, and if the number of pixels to be corrected in the image area is greater than the preset number, the image area may be used as an area to be corrected, so as to perform subsequent adjustment. In this way, the image area containing fewer pixels to be corrected can not be adjusted, so that the influence of the adjustment of the area to be corrected on the display effect can be prevented.
After the area to be corrected is determined, the gray value of the area to be corrected can be adjusted to the preset gray value threshold value, so that the brightness of the area to be corrected is increased, the diode corresponding to each pixel of the area to be corrected is in a forward bias state, and the phenomenon of smearing of the area to be corrected is prevented. Specifically, the gray value of each pixel in the region to be corrected is adjusted to a preset gray value threshold, so that the display effect is not affected by an excessive adjustment degree while the smear phenomenon is prevented.
Referring to fig. 2, 3 and 5, in certain embodiments, step 0122 comprises:
01221: dividing a display area into a plurality of adjustable areas;
01222: determining an adjustable area containing pixels to be corrected according to the image coordinates; and
01223: and when the proportion of the number of the pixels to be corrected in the total number of the pixels of the corresponding adjustable area is greater than the preset proportion, determining the adjustable area as the area to be corrected.
In certain embodiments, the determining module 12 is further configured to perform step 01221, step 01222 and step 01223. That is, the determining module 12 is further configured to divide the display area into a plurality of adjustable areas; determining an adjustable area containing pixels to be corrected according to the image coordinates; and when the proportion of the number of the pixels to be corrected to the total number of the pixels of the corresponding adjustable area is larger than the preset proportion, determining the adjustable area as the area to be corrected.
In some embodiments, processor 20 is also configured to divide the display area into a plurality of adjustable regions; determining an adjustable area containing pixels to be corrected according to the image coordinates; and when the proportion of the number of the pixels to be corrected to the total number of the pixels of the corresponding adjustable area is larger than the preset proportion, determining the adjustable area as the area to be corrected. That is, step 01221, step 01222 and step 01223 may be executed by the processor 20.
Specifically, the display area may be divided into a plurality of adjustable areas, for example, the display area is divided into 9 areas, 12 areas, 16 areas, and the like, and the processor 20 may perform overall adjustment of the display parameters for each adjustable area. Processor 20 may determine one or more adjustable regions including the pixel to be corrected from the image coordinates of the pixel to be corrected.
In order to ensure that the adjustment of the pixels to be corrected does not have a large influence on the display effect, the processor 20 may determine a ratio of the number of the pixels to be corrected in each adjustable region to the total number of the pixels in the adjustable region, and if the ratio is large (e.g., 60%, 70%, etc.), it indicates that the number of the pixels to be corrected in the adjustable region is large, and at this time, the adjustable region may be determined as one region to be corrected.
Then, the processor 20 performs overall adjustment on the region to be corrected, for example, the processor 20 first determines an adjustment value of the region to be corrected according to a preset gray value threshold, and if the preset gray value threshold is 3 and the preset gray value threshold is 1, it is determined that the gray value of the pixel to be corrected can reach the preset gray value threshold only when the adjustment value is 3, and therefore, the processor 20 can increase the gray values of all the pixels in the region to be corrected by 3, thereby implementing adjustment of the display parameters of the region to be corrected.
Therefore, the display parameters of the area to be corrected can be quickly adjusted while the phenomenon of smear is prevented, and the adjustment degree is not too large to influence the display effect.
It is understood that the display brightness of the display image is related to the driving current of the display 30 in addition to the gray scale value of each pixel, and the processor 20 may directly increase the driving current of the display 30 (i.e. the display parameters also include the driving current) to increase the brightness of the whole display image, so that the diode corresponding to each pixel of the region to be corrected is in the forward bias state, and the smearing phenomenon of the region to be corrected can also be prevented.
The adjustment value of the driving current may be determined according to the adjustment value of the gray value. The processor 20 may quickly determine the display luminance after the gray value is changed according to the adjustment value of the gray value, and then may determine the adjustment value of the driving current according to the difference between the changed display luminance and the current display luminance. Or the processor 20 may pre-store a mapping relationship between the gray-scale value and the driving current, and may quickly determine the adjustment value of the driving current according to the adjustment value of the gray-scale value, where the mapping relationship may be established according to a corresponding relationship between the change value of the gray-scale value and the change value of the driving current when the same display luminance is achieved.
Referring to fig. 2, 3 and 6, in some embodiments, the display parameters include chrominance parameters, and step 012 includes the following steps:
0123: determining the image coordinates of the pixels to be corrected, of which the chrominance parameters meet the preset chrominance parameters; and
0124: and determining the area to be corrected according to the image coordinates.
In certain embodiments, the determining module 12 is further configured to perform step 0123 and step 0124. Namely, the determining module 12 is further configured to determine the image coordinates of the pixel to be corrected, where the chromaticity parameter meets the preset chromaticity parameter; and determining the area to be corrected according to the image coordinates.
In some embodiments, the processor 20 is further configured to determine image coordinates of the pixel to be corrected whose chromaticity parameter satisfies a preset chromaticity parameter; and determining the area to be corrected according to the image coordinates. That is, steps 0123 and 0124 may be implemented by the processor 20.
Specifically, the display parameters may include chrominance parameters, each pixel may correspond to one chrominance parameter, and the color of each pixel may be determined by the chrominance parameters of each pixel, and the chrominance parameters include three channels, i.e., an R channel, a G channel, and a B channel. The processor 20 may obtain the image coordinates of the pixel to be corrected, where the chromaticity parameter of the pixel to be corrected meets the preset chromaticity parameter, for example, the preset chromaticity parameter includes the chromaticity parameter (0,0,0) of the black pixel and the chromaticity parameter (0,255,0) of the green pixel, and the processor 20 may obtain the pixel to be corrected meeting the preset chromaticity parameter according to the chromaticity parameter of each pixel, thereby obtaining the image coordinates of the pixel to be corrected. The processor 20 then determines a region to be corrected in the display image according to the image coordinates of the pixels to be corrected, where the region to be corrected is the region where the pixels to be corrected are located.
After determining the area to be corrected, the processor 20 may adjust the gray value of the area to be corrected to the preset gray value threshold, so as to increase the brightness of the area to be corrected, and make the diode corresponding to each pixel of the area to be corrected in a forward bias state, thereby preventing the area to be corrected from generating a smear phenomenon. Specifically, the gray value of each pixel in the area to be corrected is adjusted to a preset gray value threshold, so that the phenomenon of smear is prevented, and the display effect is not influenced due to the fact that the adjustment degree is not too large.
In other embodiments, the processor 20 may adjust the chromaticity parameter of the region to be corrected, so that the color of the region to be corrected is no longer pure black or pure green, and the diode corresponding to each pixel of the region to be corrected is in a forward bias state, thereby preventing the region to be corrected from generating the smearing phenomenon. For example, for a black pixel (0,0,0), the processor 20 may increase the chrominance parameters of the three channels of the black pixel, such as increasing the value of at least one chrominance parameter of the three channels, such as to be (5,0,0), (0, 5,0), (0,0,5), (5,5,0), or (5,5,5), etc.; for another example, for a green pixel (0,255,0), the processor 20 may increase the chrominance parameters of the R channel and the B channel of 0 in the green pixel, or decrease the chrominance parameters of the G channel of 255, such as to (5,255,0), (0,255, 5), (0,250,0), (5,255,0), or (5,255,5), etc.
Similarly, the display area may be divided into a plurality of adjustable areas, the processor 20 may perform overall adjustment of the chromaticity parameters for each adjustable area, and the processor 20 determines one or more areas to be corrected according to the distribution of the pixels to be corrected. The processor 20 may then adjust the chrominance parameter of any channel of the pixels in each region to be corrected, for example, increase the chrominance parameter of the R channel or the G channel of all the pixels by 5, so that the display image no longer includes pixels of pure black or pure green, thereby preventing the smear phenomenon, and simultaneously, adjusting the display parameter of the region to be corrected quickly, and the adjustment degree will not be too large to affect the display effect.
Referring to fig. 2, 3 and 7, in some embodiments, the display method further includes:
015: judging whether the current display state meets a preset state or not; and
if yes, go to step 011.
In certain embodiments, the detection device 10 further comprises a determination module 15. The determining module 15 is configured to execute step 015. The judging module 15 is configured to judge whether the current display state meets a preset state.
In some embodiments, the processor 20 is further configured to determine whether the current display state satisfies a predetermined state. That is, step 015 may be implemented by processor 20.
Specifically, under a specific application scene, even if the display brightness is lower than a preset brightness threshold, the smearing phenomenon does not occur. For example, when a static image is displayed or a user does not slide the currently displayed image, a black area or a green area which is easy to generate smear in the displayed image is basically not moved, so that the smear phenomenon does not occur, and the displayed image can be directly displayed. Therefore, the processor 20 may determine in advance whether the current display state satisfies the preset state, for example, the processor 20 may obtain display data, when the display data is static image data, the frame number of the display 30 when displaying is small, when the display data is dynamic video data, the frame number of the display 30 when displaying is large, the processor 20 may determine whether the current display frame number is greater than a preset frame number threshold, if the current display frame number is greater than the preset frame number threshold, the display data may be determined to be dynamic video data, at this time, the display image is continuously changed, thereby possibly generating a smear phenomenon, the processor 20 may enter a step of determining whether the display brightness is less than the preset brightness threshold, and when the display brightness is less than the preset brightness threshold, obtain display parameters to implement adjustment of the region to be corrected, so as to prevent the smear phenomenon.
For another example, the processor 20 may obtain a touch operation received by the display 30, and when the touch operation is a sliding operation, it indicates that the display image at this time will change, the processor 20 then proceeds to a step of determining whether the display brightness is smaller than a preset brightness threshold, and when the display brightness is smaller than the preset brightness threshold, obtains the display parameters to adjust the area to be corrected, so as to prevent the smearing phenomenon.
For another example, when determining whether the current display frame number is greater than the preset frame number threshold, the processor 20 also determines whether the touch operation is a sliding operation, and when the current display frame number is less than the preset frame number threshold but the touch operation is a sliding operation, or when the current display frame number is greater than the preset frame number threshold and the touch operation is not received, or the touch operation is not a sliding operation, the processor 20 enters a step of determining whether the display brightness is less than the preset brightness threshold, and when the display brightness is less than the preset brightness threshold, the processor obtains the display parameters to adjust the region to be corrected, so as to prevent the smear phenomenon;
referring to fig. 8, a non-volatile computer-readable storage medium 300 storing a computer program 302 according to an embodiment of the present disclosure, when the computer program 302 is executed by one or more processors 20, causes the processor 20 to perform the display method according to any of the embodiments.
For example, referring to fig. 1, the computer program 302, when executed by the one or more processors 20, causes the processors 20 to perform the steps of:
011: when the display brightness is smaller than a preset brightness threshold value, acquiring display parameters of a display image;
012: determining a region to be corrected according to the display parameters;
