Detailed Description
The technical solutions in the present application are described in further detail below with reference to the accompanying drawings.
The application discloses a display method, please refer to fig. 1, the display method comprises the following steps:
s101, acquiring a display image of a display screen, and recording the display image as an actual display image;
s102, gray scale processing is carried out on an actual display image, and a display gray scale image is obtained;
s103, acquiring a required display image and carrying out gray scale processing on the required display image to obtain a display reference image;
s104, comparing the display gray level image with the display reference image to obtain an adjustment area and an adjustment value matched with the adjustment area; and
s105, adjusting the display image according to the adjustment area and the adjustment value matched with the adjustment area;
wherein, the generation time of the display image is the same as the generation time of the required display image;
and adjusting the display image by using the same adjustment area and the adjustment value matched with the adjustment area in each unit time period.
Firstly, it is required to explain that the display method disclosed by the application is applied to a liquid crystal screen with a temperature adjusting function, and the liquid crystal screen is also called an ultra-wide temperature liquid crystal screen, and the ultra-wide temperature liquid crystal screen has wider working temperature. The working principle is that a temperature adjusting channel is established on a screen, and the transparent medium of the temperature adjusting channel enables the temperature of the ultra-wide temperature liquid crystal screen to rise or fall in a heat exchange mode in the flowing process.
However, it should be noted that, in order to balance the display effect, the number of temperature adjustment channels is limited, and at the same time, the power of the temperature adjustment channels is limited (considering the limitation of the heat transfer speed), because the ultra-wide temperature liquid crystal screen is irreversibly damaged due to the too fast temperature change rhythm.
In step S101, a display image of a display screen is first acquired and recorded as an actual display image, and the actual display image at this time is a display image on an ultra-wide temperature liquid crystal panel (hereinafter, collectively referred to as a screen) that is in the process of being heated.
After the actual display image is obtained, gray processing is carried out on the actual display image, so as to obtain a display gray image, wherein the display gray image is identical to the representation content of the actual display image in terms of gray values.
In step S103, the required display image is acquired and gray-scale processing is performed on the required display image to obtain a display reference image, and the content of the display reference image and the content of the display gray-scale image are the same, which is not described herein. The purpose of using the display reference map and the display gray map is to obtain contrast data in as short a time as possible for adjusting the actual display content on the screen.
In step S104, the display gray scale map is compared with the display reference map to obtain an adjustment region and an adjustment value matching the adjustment region, and finally in step S105, the display image is adjusted according to the adjustment region and the adjustment value matching the adjustment region.
The purpose of steps S104 and S105 is to make the actual display content as identical as possible to the required display content, and from another point of view, it is explained that the actual display content has been distorted, and the contents in steps S101 to S105 are to adjust the distortion so that the respective portions on the actual display content tend to agree, for example, a uniform color deepening or a uniform color lightening.
In addition, for the required display image, the mode of using integral distortion is added for processing, wherein the distortion of the display content on the whole screen is mainly considered in the early temperature rising or reducing process, and meanwhile, the temperature change speed near the temperature adjusting channel can be obviously higher than that of other areas.
For this case, the desired display image is first distorted as a whole and then individually adjusted in the display area in the vicinity of the temperature adjustment channel.
The method for carrying out integral distortion on the image to be displayed is that selecting an area at the middle position of two temperature regulating channels, calculating the difference value between the gray value of the area and the gray value of the corresponding area on the display reference graph, and carrying out integral distortion on the image to be displayed by means of the difference value.
In the above, the display image and the required display image are generated at the same time, so that the gray value comparison process has a comparison meaning, because the two are based on the same time point or the same temperature value.
Meanwhile, for the above adjustment process, dynamic adjustment is performed in the adjustment stage, that is, the adjustment is performed on the display image using the same adjustment area and the adjustment value matched with the adjustment area in each unit time period. The end of the dynamic adjustment process is finished when the display content on the whole display area tends to be consistent, the specific judgment mode is that the display gray level image and the display reference image are compared, when the display gray level image and the display reference image tend to be consistent, the display method disclosed by the application is stopped, the standard of the trend to be consistent is that a plurality of points are randomly selected on the display gray level image and the display reference image, then the difference value of gray level values of the points is calculated, and if the consistency of the difference value meets the requirement (is distributed in a required range), the display method disclosed by the application is stopped.
In some examples, referring to FIG. 2, the desired display image includes an adjusted area image and a non-adjusted area image, with the heater wire on the display screen being positioned within the adjusted area image. The adjustment range can be controlled by dividing the required display image, so that the data processing amount can be reduced, and the display content can be more stable, because the adjustment is performed on the non-adjustment region image, and a macroscopic limit exists between the non-adjustment region image and the adjustment region image.
In some examples, the minimum distance between the edge of the adjustment area image and the heating wire in the direction perpendicular to the heating wire on the plane on which the display screen is located is equal to or less than the allowable adjustment distance, and the range of the adjustment area image is limited.
It will be appreciated that the minimum distance between the edge of the adjustment area image and the heater wire is relatively small in the early adjustment stage, but the range of the adjustment area image becomes larger as the screen temperature increases, which means that the data processing amount starts to gradually increase.
The range of the image of the adjustment area can be limited by using the allowable adjustment distance, meanwhile, the temperature of the whole screen tends to be uniform in the middle and later stages of the temperature adjustment process, and the display content on the screen tends to be uniform due to the reduction of the temperature difference.
The manner of limiting the range of the adjustment region image can enable the display method disclosed in the application to exit in time, because the adjustment is performed again at this time, and the influence on the actual visual perception is limited. Meanwhile, the content related to stopping using the display method disclosed in the application is limited to only the comparison and adjustment area image range.
In some examples, referring to fig. 3, determining edges of the adjustment region image includes:
s201, drawing a dynamic adjustment area image edge line parallel to a heating line;
s202, selecting a plurality of contrast points or a plurality of contrast areas on an edge line of an image of a dynamic adjustment area;
s203, calculating the gray value difference between the actual display image and the required display image on the contrast points or the contrast areas; and
s204, stopping moving the image edge line of the dynamic adjustment area when the gray value difference value of the contrast points or the contrast areas exceeding the set proportion or the set quantity is within the allowable range;
the display screen is positioned on a plane, and the image edge line of the dynamic adjustment area moves in the direction perpendicular to the heating line;
when the minimum distance between the edge line of the dynamic adjustment area image and the heating wire is equal to the allowable adjustment distance, the edge line of the dynamic adjustment area image stops moving;
when the dynamic adjustment area image edge line is overlapped with another dynamic adjustment area image edge line, both dynamic adjustment area image edge lines stop moving.
The contents of steps S201 to S204 show the area change process of the adjustment area image in the display image (including the adjustment area image and the non-adjustment area image), because the area of the adjustment area image increases as the heat transfer process proceeds, and thus dynamic adjustment of the boundary of the adjustment area image is required.
The adjustment basis (step S202 and step S203) is to select a plurality of contrast points (shown in fig. 4) or a plurality of contrast areas (shown in fig. 5) on the edge line of the image in the dynamic adjustment area and calculate the gray value difference between the actual display image and the required display image on the contrast points or the contrast areas.
In step S204, when the gray value difference of the contrast points or the contrast areas exceeding the set proportion or the set number is within the allowable range, the movement of the dynamic adjustment area image edge line is stopped, that is, the dynamic adjustment area image edge line is in the moving process, until the movement is stopped when the dynamic adjustment area image edge line meets the requirement.
And in each unit time period, the position of the edge line of the image of the dynamic adjustment area is adjusted once.
In some examples, the following is also added:
s301, continuously acquiring the difference value between the gray value of the actual display image and the gray value of the required display image in the same area on the time sequence;
s302, calculating the variation amplitude of a plurality of difference values on a sequential sequence; and
s303, adjusting the length of the unit time period according to the change amplitude;
wherein the length of the unit time period and the variation amplitude show positive correlation.
The content of steps S301 to S303 is to dynamically adjust the unit time period length, mainly considering that the temperature rise on the screen is not linear. The dynamic adjustment of the length of the unit time period is based on the difference between the gray value of the actual display image and the gray value of the required display image in the same area, when the difference is small, the length of the unit time period is properly prolonged, and when the difference is large, the length of the unit time period is properly shortened.
In some examples, in the first stable interval of the variation range, the heating power of the display screen is further adjusted according to the variation range, specifically, referring to fig. 6, the adjusting the heating power of the display screen includes:
s401, selecting a plurality of time points in a stable interval of a first variation amplitude;
s402, acquiring a change amplitude value at each time point and calculating a change amplitude value average value;
s403, comparing the second and subsequent variation amplitude averages with the first variation amplitude average value in the sequence to obtain a reference difference value; and
s404, adjusting the heating power of the display screen according to the reference difference value.
The first stable interval of the variation range refers to the variation range of the plurality of differences over the calculation sequence in step S302, and the first stable interval of the variation range refers to the temperature rising process, and the subsequent stable interval corresponds to the temperature fluctuation in the heat preservation stage.
When heating power is adjusted, a plurality of time points are selected in a stable interval of a first change amplitude, a change amplitude number average value at one time point is obtained, and the change amplitude number average value is obtained by carrying out average value calculation on the change amplitude number value at each time point.
The number average value of the variation amplitude reflects the corresponding relation between the temperature and the image in a period of time, and the larger the number average value of the variation amplitude is, the deviation degree of the actual display image and the required display image on the screen is indicated, and the heating power of the display screen is required to be adjusted, increased or reduced according to the deviation degree.
In addition, when the degree of deviation is calculated, there are positive deviation and negative deviation, which correspond to decrease and increase of the heating power, respectively.
For the stable section of the first variation amplitude, the following manner is used for determination: in the stable section of the first variation amplitude, the sequential connection line where the time points exceeding the set proportion number exist in the first allowable section range or the time points exceeding the set proportion length exist in the second allowable section range.
