The technical means of the present invention will be described in detail with reference to specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In practical applications, in order to observe the situations of a plurality of different locations at the same time and ensure the safety of each location, a plurality of monitoring devices are usually disposed in different areas of each location, and monitoring pictures corresponding to the plurality of monitoring devices are simultaneously displayed on one OLED display, so as to observe the situations of each area, and the OLED display may be an OLED display screen.
For convenience of observation, each monitoring picture is generally placed at a position corresponding to a display screen, in order to ensure the safety of an area where the monitoring equipment is located, the monitoring equipment is generally in a continuous working state, so that the monitoring picture is also displayed in the display screen for a long time, and the display screen may be heated due to continuous working for a long time, so that the service life of the display screen is reduced, the invention adopts the following scheme in order to improve the condition:
referring to fig. 1, a schematic diagram of a temperature control data processing method for an OLED display according to an embodiment of the present invention is shown, where an execution main body of the method shown in fig. 1 may be a software and/or hardware device. The execution subject of the present application may include, but is not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, a computer, a smart phone, a Personal Digital Assistant (PDA), and the electronic devices mentioned above. The network device may include, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a cloud consisting of a large number of computers or network servers based on cloud computing, wherein cloud computing is one of distributed computing, one super virtual computer consisting of a group of loosely coupled computers. The present embodiment does not limit this. The method comprises the following steps of S1 to S5:
s1, initially sequencing a plurality of monitoring areas in an OLED display according to setting data of workers to obtain a first area sequence related to the plurality of monitoring areas, and acquiring a first pixel value of each monitoring area.
The first region sequence refers to a sequence obtained according to an initial sequence, and the initial sequence can be preset according to the observation habit of workers and can also be set according to the region sequence monitored by each monitoring device; the first pixel value refers to an average value of the sum of the pixel values of all the pixels in the monitoring picture corresponding to each monitoring area.
It should be noted that, because the monitoring picture corresponding to each monitoring area is composed of a plurality of pixels, and the pixel values of the pixels are different, for the subsequent processing, the first pixel value in this scheme is an average value of the sum of the pixel values of all the pixels in each monitoring picture, and in addition, the first pixel value may also be the sum of the pixel values of all the pixels in each monitoring picture.
The pixel value is larger, the required current is larger, the corresponding display screen is easier to heat, and the temperature is higher, so that the first pixel value is obtained by the method, the temperature value corresponding to each monitoring area does not need to be acquired one by one, and the applicable scene of the scheme is better met.
And S2, dividing the monitoring area according to the first pixel value to obtain a target area and a swap area, taking the first pixel value in the target area as a second pixel value, and taking the first pixel value in the swap area as a third pixel value, wherein the second pixel value is higher than the third pixel value.
The target area refers to an area needing to reduce the temperature of the display screen part of the target area, the exchange area refers to an area exchanged with the area needing to reduce the temperature of the display screen part of the target area, the second pixel value refers to the average value of the sum of the pixel values of all the pixel points in the target area, and the third pixel value refers to the average value of the sum of the pixel values of all the pixel points in the exchange area.
It can be understood that most display screens adopt RGB color standards, any color on the screen can be expressed and recorded by a set of RGB values, RGB is designed from the principle of color lighting, and in popular terms, it is the color mixing manner as if there are three lamps of red, green and blue, when their lights are superimposed, the colors are mixed, but the brightness is equal to the sum of the brightness of the three lamps, and the higher the mixed brightness is, the additive mixing is performed. When the three-color gray values are the same, gray tones with different gray values are generated, namely, the darkest black tone is generated when the three-color gray values are all 0; when the three-color gray scale is 255, the brightest white tone is obtained.
When the second pixel value is higher than the third pixel value, the temperature of the target area corresponding to the second pixel value is higher than the swap area corresponding to the third pixel value.
Based on the above, in the present scheme, the target area and the swap area are swapped, so that the brightness of the original position of the target area is reduced by swapping the brightness of the swap area, and the current passing through the target area is reduced, thereby improving the temperature of the area which is originally in continuous heating in the display screen to prolong the service life thereof, wherein the specific division of the target area and the swap area includes steps S21 to S23.
S21, sequencing the plurality of monitoring areas in an ascending order according to the numerical relation of the first pixel values to obtain a second area sequence, taking the monitoring area positioned in the middle position in the second area sequence as a comparison area, and extracting the first pixel values of the comparison area as comparison pixel values.
In other embodiments, the second region sequence may also be a sequence formed by arranging the monitoring regions in descending order from large to small according to the first pixel values.
The comparison area refers to a monitoring area which is positioned in the middle of the second sequence, and if only one monitoring area is positioned in the middle, the monitoring area is used as the comparison area; if there are two monitoring areas in the middle position, the two monitoring areas are used as comparison areas.
When one comparison area exists, the comparison pixel value refers to the average value of the sum of the pixel values of all the pixel points in the comparison area; when there are two comparison areas, the comparison pixel value refers to the average value of the sum of the first pixel values of the two comparison areas.
S22, taking the monitoring area with the first pixel value larger than the comparison pixel value as a target area, and taking the monitoring area with the first pixel value smaller than the comparison pixel value as a swap area.
And S23, determining the comparison area at the middle position as any one or more of a target area, a transposition area and a fixed area according to the number of the comparison areas at the middle position.
In practical application, in order to reduce the brightness of the original position of the target area by replacing the target area with the exchange area, so as to improve the temperature of the display screen, the scheme divides the first pixel value of each monitoring area into the target area, the exchange area and a fixed area according to the comparison of the first pixel value of each monitoring area and the comparison pixel value of the comparison area, wherein the fixed area refers to the monitoring area which is not exchanged.
Specifically, in the scheme, after the comparison pixel value is obtained by S21 (in which the plurality of monitoring regions are sorted in an ascending order according to the numerical relationship of the first pixel value to obtain a second region sequence, the monitoring region located at the middle position in the second region sequence is used as the comparison region, and the first pixel value of the comparison region is extracted to be used as the comparison pixel value), since the pixel value of the comparison pixel value is located at the middle position, the monitoring region where the first pixel value is greater than the comparison pixel value can be used as the target region, and the monitoring region where the first pixel value is less than the comparison pixel value is used as the exchange region.
When the target region and the transposed region are distinguished in the above manner, the number of the alignment regions may be 1 or 2, and in this case, the target region, the transposed region, and the fixed region may be further determined through the following two steps.
If the number of the comparison areas at the middle position is 2, the comparison area corresponding to the comparison pixel value with a larger numerical value is used as the target area, and the comparison area corresponding to the comparison pixel value with a smaller numerical value is used as the swap area.
If the number of the comparison areas at the middle position is 1, taking the comparison areas as fixed areas, and not adjusting the monitoring areas corresponding to the fixed areas.
Referring to fig. 2, if the number of the comparison areas at the middle position is 2, the area with the larger pixel value is used as the target area, the area with the smaller pixel value is used as the swap area, the monitoring area with the first pixel value larger than the comparison pixel value in the remaining monitoring areas is used as the target area, and the monitoring area with the first pixel value smaller than the comparison pixel value is used as the swap area.
Referring to fig. 3, the number of the comparison areas at the middle position is 1, and since there is no exchange between the monitoring area and the comparison area, the comparison area at this time is taken as the fixed area, the monitoring area with the first pixel value greater than the comparison pixel value is taken as the target area, and the monitoring area with the first pixel value less than the comparison pixel value is taken as the exchange area.
The target area and the exchange area are obtained through the method, so that the monitoring area is divided without acquiring the temperature corresponding to each monitoring area, the cost is saved, the target area and the exchange area can be divided intelligently and efficiently through the method, and the processing efficiency is improved.
And S3, generating a swap correspondence table according to the numerical relationship between the second pixel value of the target area and the third pixel value of the swap area, generating a corresponding temperature coefficient according to the second pixel value of each target area, and generating a first monitoring time of each target area according to the temperature coefficient.
The exchange corresponding table is a corresponding table formed by the target area and the exchange area which is exchanged correspondingly, the temperature coefficient is a coefficient corresponding to the temperature of each target area, the temperature of the corresponding target area display screen part is higher when the temperature coefficient is higher, and the first monitoring time is a time period before the target area and the exchange area are exchanged.
Specifically, the corresponding relationship between each target region and each swap region may be obtained based on the second pixel value of the target region and the third pixel value of the swap region, and the swap correspondence table may be generated after the corresponding relationship between each target region and each swap region is obtained.
In some embodiments, the swap mapping table may be obtained through steps S31 to S35, which are as follows:
and S31, decomposing the second region sequence according to the positions of all the target regions to obtain a third region sequence, wherein all the third region sequences are the target regions.
And S32, decomposing the second region sequence according to the positions of all the regions to obtain a fourth region sequence, wherein all the regions in the fourth region sequence are regions to be exchanged.
Wherein the third region sequence refers to a sequence consisting of the target region, and the fourth region sequence refers to a sequence consisting of the transposed region.
Specifically, in the present scheme, in order to correspond the target regions and the swap regions one to one, all the target regions are divided into the third region sequence, and all the swap regions are divided into the fourth region sequence.
And S33, sequencing the target regions in an ascending order according to the numerical relationship of the second pixel values to obtain a third region sequence related to the plurality of target regions.
And S34, sequencing the swap areas in a descending order according to the numerical relation of the third pixel values to obtain a fourth area sequence related to a plurality of swap areas.
It can be understood that, in the present scheme, the target area is sorted in an ascending order according to the second pixel value, and the swap area is sorted in a descending order according to the third pixel value, so that the target area with the higher second pixel value is swapped with the swap area with the lower third pixel value.
The higher the second pixel value is, the larger the current flowing through the portion of the display screen corresponding to the target area is, the more easily the corresponding display screen generates heat, and the target area with the higher second pixel value is exchanged with the exchanged area with the lower third pixel value, so that the luminance of the portion of the display screen corresponding to the original target area is reduced faster, the corresponding current is reduced faster, and the temperature is reduced faster accordingly.
And S35, acquiring a target region and a swap region which are positioned in the same sequence in the third region sequence and the fourth region sequence, and corresponding the target region and the swap region which are positioned in the same sequence to obtain a swap correspondence table.
Specifically, after the third region sequence after ascending sorting and the fourth region sequence after descending sorting are obtained in the above manner, the target region and the swap region in the same sequence may be corresponded to obtain the swap correspondence table.
For example, when the number of the target regions and the number of the swap regions are 3, and the target region sequence having the largest second pixel value is 3, the swap region sequence having the smallest third pixel value corresponding thereto is also 3.
The change correspondence table is obtained in the above mode, the target area and the change area do not need to be subsequently in one-to-one correspondence, the target area and the corresponding change area can be found only according to the change correspondence table, and the method is very convenient and fast.
In other embodiments, the first monitoring time may be obtained through steps S36 to S38, which are as follows:
and S36, acquiring target pixel values corresponding to the plurality of pixel points in the target area, and summing the target pixel values corresponding to the plurality of pixel points to obtain a total target pixel value.
The target pixel value refers to a pixel value corresponding to each pixel point in the target area, and the total target pixel value refers to the sum of pixel values corresponding to a plurality of pixel points in the target area.
In practical application, each color in the display screen is composed of different pixel values of each pixel point, and since the monitoring pictures in the target areas are different, the pixel values corresponding to the pixel points in the target areas are also different.
Specifically, the sum of the pixel values corresponding to each target area can be obtained by obtaining the sum of the pixel values of a plurality of pixel points in each target area.
And S37, obtaining a second pixel value corresponding to each target area according to the average value of the total target pixel values, and obtaining a pixel offset coefficient corresponding to each target area according to a preset pixel value and the second pixel value.
The second pixel value refers to an average value of the sum of the pixel values corresponding to each target area, the preset pixel value may be preset according to an actual situation, and the pixel offset value refers to a ratio of the second pixel value to the preset pixel value.
Specifically, after the sum of the pixel values of each target area is obtained, the second pixel value is obtained according to the average value of the sum of the pixel values, and the pixel offset coefficient is obtained according to the ratio of the second pixel value to the preset pixel value, so as to facilitate subsequent processing.
And S38, obtaining a temperature coefficient corresponding to each target area according to the reference temperature coefficient and the pixel migration coefficient, and obtaining first monitoring time corresponding to the target area according to first monitoring time reference monitoring time and the temperature coefficient.
The first monitoring time is calculated by the following formula,
wherein,
in order to be a temperature coefficient of the temperature,
is a first
The first one of the target pixel values is,
is the upper limit value of the first target pixel value,
is the value of the second pixel and is,
in order to preset the value of the pixel,
for the pixel to be shifted by the coefficient weight,
as a reference temperature coefficient, a temperature coefficient,
in order to be the first monitoring time, the monitoring time is,
in order to be the weight of the temperature coefficient,
the time was monitored as a reference.
The main idea of the above formula is:
when the second pixel value
The larger the current flowing through the target area is, the higher the temperature of the display screen part corresponding to the target area is, and the temperature coefficient
The temperature of the portion of the display screen corresponding to the target area, so that the second pixel value is
The greater the temperature coefficient
The larger will be the corresponding.
Coefficient of temperature
The larger the temperature of the portion of the display screen corresponding to the target area, the higher the temperature, and therefore the temperature of the display screen needs to be lowered as quickly as possible even if the target area is exchanged with the corresponding exchanged area as quickly as possible. Therefore when the temperature coefficient
The larger the time, the first monitoring time
The smaller will be.
It should be noted that the reference temperature coefficient in the above formula
And a preset pixel value
Are correspondingly set, different reference temperature coefficients
Will correspond to different preset pixel values
(ii) a Weight value of pixel offset coefficient
And weight value of temperature coefficient
Will be related to environmental factors and use conditionsEtc., e.g. weight value of pixel shift coefficient when room temperature changes
And weight value of temperature coefficient
The up-scaling or down-scaling process can be performed accordingly.
The first monitoring time is obtained through the mode, so that the target areas with different second pixel values can be exchanged with the corresponding exchange areas according to different first monitoring times, the temperature of the display screen part corresponding to the target area with the large second pixel value can be reduced first, and the reduction of the service life of the display screen part due to long-time heating is prevented.
And S4, monitoring the screen display time of the target area, and exchanging the target area and the exchange area according to the exchange correspondence table when the screen display time is more than or equal to the first monitoring time.
Specifically, when the screen display time of the target area is monitored to be greater than or equal to the first monitoring time, the target area and the exchange area are exchanged according to the exchange correspondence table, wherein the screen display time refers to the working time of the display screen part corresponding to the target area.
In practical application, the target area and the swap area are generally swapped when the screen display time of the target area is equal to the first monitoring time, but sometimes the screen display time of the target area may be greater than the first monitoring time, so in order to prevent the target area and the swap area from not being swapped when the screen display time of the target area is greater than the first monitoring time, the scheme selects to swap the target area and the swap area when the screen display time of the target area is greater than or equal to the first monitoring time.
The step S4 (monitoring the screen display time of the target area, and exchanging the target area and the exchange area according to the exchange correspondence table when the screen display time is equal to or longer than the first monitoring time) further includes the following steps S41 to S42.
And S41, generating a first transposition time corresponding to each target area according to a preset reference transposition time and the temperature coefficient.
Wherein the first exchange time refers to a time period for exchanging the target region and the exchange region after exchanging, and the reference exchange time may be preset according to an actual situation.
It is understood that, after the target area and the swap area are swapped, in order to lower the temperature of the display screen portion corresponding to the target area, a first swap time may be set to lower the temperature of the display screen portion corresponding to the target area within the first swap time.
And S42, when the screen display time is more than or equal to the first monitoring time, exchanging the target area and the exchange area for the first exchange time according to the exchange corresponding table so as to reduce the temperature of the part of the display screen corresponding to the target area before exchange.
Specifically, when the screen display time of the monitored target area is greater than or equal to the first monitoring time, the exchanged target area and the exchanged area may be exchanged within the first exchange time, so that the temperature of the display screen portion corresponding to the target area is reduced within the first exchange time.
The first zapping time is calculated by the following formula,
wherein,
in order to perform the first change-over time,
is a first
The first one of the target pixel values is,
is the upper limit value of the first target pixel value,
is the value of the second pixel and is,
in order to preset the pixel value of the pixel,
for the pixel to be shifted by the coefficient weight,
as a reference temperature coefficient, a temperature coefficient,
in order to be the weight of the temperature coefficient,
as a reference cooling time, the cooling time was,
are training values.
And displaying the first exchange time, and if confirmation information of workers is received, taking the first exchange time as the final first exchange time.
From the above formula, the second pixel value
With the first change time
In direct proportion to the second pixel value
The larger the size, the target area is specifiedThe higher the brightness value of the target area is, the larger the current of the target area is, the higher the temperature of the display screen part corresponding to the corresponding target area is, the longer the exchanging time period after exchanging the target area is, and the first exchanging time period
The larger will be.
In practical application, due to the first swap time
Is calculated by a formula, so that the calculated first zapping time may occur
Meeting applicable scenarios, or calculated first swap time
Situations occur where the applicable scenario is not satisfied.
When the calculated first zapping time
When the applicable scene is met, namely the confirmation information of the staff is received, the first exchange time calculated at the moment can be used
As a final first swap time.
When the calculated first zapping time
When the applicable scene is not satisfied, the training values can be corrected through the correction time input by the staff
Making a correction by the corrected training value
The formula is adjusted to be more suitable for the application scene of the scheme.
And if receiving modification information input by a worker through an input device, taking the modification time in the modification information as the final first exchange time.
It can be understood that, when modification information input by a worker through an input device is received, it is described that the first swap time obtained through a formula at this time does not satisfy the applicable scenario, and at this time, the modification time in the modification information may be used as the final first swap time so that the modified first swap time conforms to the applicable scenario.
Wherein, the modification time in the modification information can be input by a worker according to the actual situation.
And correcting the training numerical value according to the correction time input by the input equipment to obtain a corrected training numerical value.
In practical applications, in order to prevent the calculated first swapping time from being inconsistent with the applicable scenario, the first swapping time may be adjusted by correcting the training value, where the corrected training value refers to the corrected training value.
The modified training value is calculated by the following formula,
wherein,
for the purpose of the final first zapping time,
in order to adjust the training values, the training data is,
in order to increase the weight of the correction,
to reduce the correction weight.
The main concept of the above formula is:
when the final first swap time
Greater than the first swap time
When the first switching time calculated at this time is described
Is small, and then the training value can be adjusted
Performing a first transposition process for a first transposition time
Closer to the final first zapping time
。
When the final first swap time
Less than the first swap time
When the first switching time calculated at this time is described
Is larger, and then the training value can be obtained
Performing a reduction process to make the first swap time
Closer to the final first zapping time
。
In particular, when the final first zapping time
Greater than the first change-over time
When it is, above
The larger the first zapping time calculated at this time is, the larger the time is
The smaller the size of the first transposition time
With final first change-over time
More closely, more increased training values are required
By increasing the training value
Obtaining the adjusted training value
(ii) a When the final first swap time
Less than the first swap time
When it is, above
The larger the first zapping time calculated at this time is, the larger the time is
The larger the size of the first change-over time
With final first change-over time
More closely, more reduced training values are required
By decreasing the training value
Obtaining the adjusted training value
. Through this kind of mode for when calculating first transposition time next time, can have the final first transposition time that more is fit for current calculation scene, the calculation scene of first transposition time each time can be the time interval that corresponds different, and this time interval can be that the staff sets up in advance, for example the time interval that corresponds daytime, the time interval that corresponds night.
Obtain first change time through above-mentioned mode, can make different target areas make its corresponding display screen partial temperature obtain appropriate reduction in the time quantum of difference, neither need the staff to set up the first change time that the target area corresponds respectively, can make the adjustment according to the applicable scene of reality is timely moreover, make the first change time of calculating more accurate.
And S5, if the input equipment is judged to have the corresponding input signals, controlling an OLED display to sequence the target area and the exchange area according to the first area sequence.
The input device may be a mouse or a keyboard. When the staff wants to check the monitoring picture, the monitoring picture can be checked through the input signal which the input device has.
In practical application, each monitoring picture usually corresponds to a specific monitoring area, so that the position of each monitoring picture in a display screen is generally fixed and unchanged for the convenience of observation of a worker, but the corresponding position of each monitoring picture is changed by the scheme, so that when the worker views the monitoring pictures by using the input equipment, all the monitoring pictures can be restored to the original positions, namely, the target area and the exchange area are reset according to the first area sequence.
After S5 (if the input device is determined to have the corresponding input signal, the OLED display is controlled to sequence the target region and the swap region according to the first region sequence), the following steps S51 to S53 are further included.
And S51, after judging the preset time period for the input equipment to stop inputting signals, determining the viewing time of the input equipment, and exchanging the target area and the exchanged area according to the exchange corresponding table.
The preset time period refers to a time period after the input device stops inputting the signal, and can be preset according to actual conditions; the viewing time refers to the time for the staff to view the monitoring picture.
In practical application, when a worker checks a monitoring picture, in order to prevent the monitoring picture from being immediately switched, the scheme also sets a preset time period as a buffering time period.
For example, when the input device is a mouse, a mouse arrow in the display screen may be used as the input signal, and when the mouse arrow moves in the display screen, it may be considered that the monitoring picture is being viewed by the worker at this time.
And S52, acquiring the residual time period of the first exchange time, obtaining second exchange time corresponding to the target area according to the sum of the residual time period, the viewing time and the preset time period, and continuously reducing the temperature of the part of the display screen corresponding to the target area according to the second exchange time.
The remaining time period refers to the time period of the first exchange time, and the second exchange time refers to the exchange time period after the target area and the exchange area are exchanged again after the monitoring picture is checked by the staff.
In practical application, the target area and the exchange area may be just exchanged, a worker checks the monitoring picture, and the target area and the exchange area are reset when the worker checks the monitoring picture, at this time, although the target area and the exchange area are not exchanged within the first exchange time, the temperature of the part of the display screen corresponding to the target area is not correspondingly reduced.
In order to solve the above problem, the second swap time corresponding to the target area is set to improve the target area. The second exchange time prolongs the first exchange time on the basis of the first exchange time, makes up the viewing time and the preset time period for the staff to view the monitoring picture in the first exchange time, and enables the temperature of the display screen part corresponding to the target area to be continuously reduced.
It should be noted that, sometimes, a situation may occur that the viewing time for the staff to view the monitoring picture spans the first monitoring time and the first swapping time, and since the target area and the swapping area are not swapped in the first monitoring time, the first swapping time is not affected much, and therefore the effect of the situation on the first swapping time is not considered in the present scheme.
S53, when the screen display time is larger than or equal to the second exchange time, controlling the OLED display to reset the target area and the exchange area according to the first area sequence.
It can be understood that, when the screen display time is greater than or equal to the second swap time, the temperature of the display screen portion corresponding to the swapped target region will increase, and the temperature of the display screen portion corresponding to the original target region (i.e., the display screen portion corresponding to the swapped region after the swap) will decrease, at which time the target region and the swap region can be reset, so as to ensure that the temperature of the display screen portion corresponding to the swapped target region will not be continuously increased.
The second exchange time is obtained by the method, the influence of the checking time and the preset time period for checking the monitoring picture in the first exchange time by the working personnel on the first exchange time can be improved, and the temperature of the part, corresponding to the target area, of the display screen is reduced better.
