Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the present disclosure provides a screen repairing method, and fig. 1 is a first flowchart illustrating a screen repairing method according to an exemplary embodiment, and as shown in fig. 1, the screen repairing method includes the following steps:

step 101, determining damage degrees of a plurality of screen division areas;

step 102, determining whether the corresponding screen division area belongs to an area to be repaired according to the damage degree;

and 103, if the region belongs to the region to be repaired, performing screen repair on the region to be repaired.

It should be noted that the screen repairing method may be applied to any electronic device with a screen, for example, a computer, a smart phone, a smart watch, a television, and the like, and the disclosure does not limit this.

In an embodiment of the present disclosure, the screen at least includes: organic light emitting semiconductor (OLED) screens. The OLED screen is driven by an electric field, and the organic semiconductor material and the luminescent material in the screen realize luminescence after carrier injection and recombination. In essence, the transparent glass electrode is used as the anode of the device, the metal electrode is used as the cathode, electrons are transported from the cathode to the electron transport layer by the power drive, holes are injected from the anode to the hole transport layer, and then the electrons and the holes are respectively transferred to the light emitting layer, and excitons are generated after the electrons and the holes meet each other. The excitons excite the luminescent molecules to generate light after radiation. Thus, one OLED screen consists of millions of small bulbs.

Due to the light-emitting characteristics of the OLED screen, the OLED screen is damaged along with the prolonging of the service time, and the problem of image sticking is most common. Most of the damaged areas on the whole screen are concentrated in the center of the screen, or some positions where highlighted or static icons are displayed for a long time, for example, in the case of a television, ghost shadow usually appears at the position of a station logo of a radio station; while others are damaged to a lesser extent. At this time, if the entire screen is repaired indiscriminately after a certain limit value is reached by judging whether the screen use time reaches the certain limit value, the problem of damage of the organic material due to frequent repair of the entire screen occurs.

For the problem, the embodiment of the present disclosure provides a scheme for determining damage degrees of a plurality of screen division regions obtained after screen division, and then respectively repairing the screen division regions according to different damage degrees.

Here, the screen needs to be divided before determining the degree of damage of the plurality of screen division regions.

In the embodiment of the present disclosure, the dividing of the screen may include:

the screen is divided into N regions (i.e., N screen division regions are obtained) according to the size of the screen, where N is a positive integer.

For example, the screen is divided into 9 total areas of 3 × 3, which are respectively denoted as a0, a1, and a2.. a8 areas.

In the division of the screen, the screen may be divided into equal areas, that is, N screen division regions with equal areas are obtained. For example, the areas of the a0, a1, a2.. A8 regions are all equal.

Or, the area may be divided into different areas, that is, N screen division areas with incompletely equal areas are obtained, for example, the screen is divided into: a screen division region a in the middle, screen division regions B, C, D and E in the periphery, the area of the screen division region a being an integral multiple, for example, 2 times, the area of the screen division regions B, C, D and E.

In other embodiments, the dividing of the screen may further include:

and dividing the screen according to the layout information of the pictures with higher occurrence frequency to obtain N screen division areas.

For example, if the electronic device is a television, the pictures appearing on the television with higher frequency may be television programs broadcast by each satellite, and the layouts of the display pictures appearing when the television programs of each satellite are broadcast are: the TV station caption is displayed at the upper left corner of the picture, the information bar is displayed in a rolling way at the lower part of the picture, and the other positions are the positions for mainly playing information. Because the television station caption and the information bar displayed in a rolling way at the lower part exist all the time in the process of playing the picture, the two positions can be highlighted all the time, and the possibility of damage is high.

At this time, the minimum division unit can be determined according to the display area and the display position of the television station caption. Thus, the dividing the screen according to the layout information of the pictures with higher occurrence frequency to obtain N screen division regions includes:

determining a minimum division unit of the screen according to the display area and the display position of the television station caption;

and dividing the screen based on the total area of the screen and the minimum dividing unit to obtain N screen dividing regions.

Here, dividing the screen based on the layout information of the picture whose appearance frequency is high may be ascribed to the division of the unequal areas of the screen due to the limitation of the layout information.

In this division, the minimum division unit means: and a unit corresponding to the screen division region with the minimum area in the N screen division regions obtained after the screen division. The minimum dividing unit may be a rectangular unit, a circular unit, or the like, or may be other irregular units, which is not limited in this disclosure.

Taking the example that the minimum division unit is a rectangular unit, the minimum division unit may be a unit determined by the display position and the display area of the television station caption. That is, a region having the same area as the display area is divided at the display position of the tv logo as a minimum division unit.

In other embodiments, the minimum partition unit may also be: and dividing a region with the area being the multiple of the display area of the television station caption by taking the display position of the television station caption as the center.

The division mode is realized by combining with the actual display condition, so that the important restoration can be directly carried out on some fixed areas in the subsequent restoration, and the restoration speed can be higher.

Further, after the screen is divided, it is necessary to determine the degree of damage of each of the divided areas of the screen. As described above, the degree of damage due to the screen is related to the brightness and the use time of the screen. In an embodiment of the present disclosure, the determining the damage degree of the plurality of screen division areas may be: the damage degree of the plurality of screen division regions is determined by performing statistics of display brightness and display time duration for each screen division region. The specific implementation is described in detail later.

It should be noted that, in another embodiment, the determining the damage degree of the plurality of screen division areas further includes:

and determining the damage degree of the plurality of screen division areas after the service time of the screen reaches a preset time threshold.

The size of the preset duration threshold is related to screen parameters, such as the model of the screen or the durability of the material, and the size of the preset duration threshold can be set according to needs, which is not limited by the present disclosure.

That is, since the damage degree is obtained by acquiring some parameters corresponding to the screen, some operations need to be performed on the screen. If the damage degree of a plurality of screen division regions is determined in real time, the system load is increased, and the screen repair is not greatly facilitated. Moreover, most screens are damaged slowly after being used for a period of time, so that the step of determining the damage degree of the divided areas of the screens is started after the use time of the screens reaches the preset time threshold value, and thus, the system load can be reduced as much as possible.

Here, when the screen displays a picture, different regions on the screen are damaged to different degrees in the using process due to different picture structures, for example, a region at the upper left corner of the screen may be damaged to a higher degree, and a lower middle part of the screen may be damaged to a lower degree. While the screen may not necessarily be repaired when it is at a low level of damage, or, alternatively, when it is not damaged. Thus, before performing formal screen repair, the embodiments of the present disclosure need to determine whether each screen partition region belongs to a region to be repaired. Only the screen division area belonging to the area to be repaired performs screen repair.

Thus, by performing the processes separately for different damage levels, other undamaged portions can be reduced, or damage to the organic material due to frequent repair of less damaged portions can be avoided.

In some embodiments, fig. 2 is a flowchart illustrating a second screen repairing method according to an exemplary embodiment, where as shown in fig. 2, in step 102, the determining whether the corresponding screen partition region belongs to a region to be repaired according to the damage degree includes:

and step 1021, when the damage degree is larger than the preset damage threshold value, determining that the corresponding screen division area belongs to the area to be repaired.

Here, a damage threshold is preset to measure whether the screen division area currently damaged needs to be repaired.

The preset damage threshold may be determined based on the model of the screen or the durability of the material.

The relevant parameters of the screen, such as the manufacturer, the material of the screen, the size of the screen, etc., are obtained based on the model of the screen. And the material of the screen may have a direct influence on the durability of the screen. For example, for a screen with a higher durability of the material, the preset damage threshold may be set higher.

Because the picture composition is different when the screen displays the picture, the damage degree of different areas on the screen is different in the using process, and the screen is in a lower damage degree or is unnecessary to be repaired when the screen is not damaged. Therefore, by setting the preset damage threshold value, targeted processing can be realized, and any damage degree is prevented from being repaired, so that the cost is reduced, and the damage caused by frequent repair is also reduced.

Here, the determination process may be: and comparing the damage degree of each screen division region with a preset damage threshold value, and when the damage degree is greater than the preset damage threshold value according to the comparison result, determining that the screen division region corresponding to the damage degree belongs to the region to be repaired. And when the damage degree is smaller than or equal to the preset damage threshold value according to the comparison result, the screen division region corresponding to the damage degree is not considered to belong to the region to be repaired.

In some embodiments, as shown in fig. 2, in step 103, if the area to be repaired belongs to the area to be repaired, performing screen repair on the area to be repaired includes:

step 1031, if the damaged area belongs to the area to be repaired, determining a repair grade to which the damaged degree belongs;

and 1032, performing screen repair on the area to be repaired according to the repair strategy corresponding to the repair grade.

The damage degree is divided into different grades according to the embodiment of the disclosure, and the different grades correspond to different repairing modes. In order to implement automatic execution of corresponding repair, the electronic device according to the embodiment of the present disclosure stores in advance: and mapping relation between damage level and repair strategy and execution action.

As shown in table 1 below, table 1 is a mapping relationship between the damage level of the screen and the repair policy and the execution action.

Grade name	Grade of damage	Repair strategy	Performing an action
				Without damage	L0	Need not repair	Action(none)
Minor injury	L1	Minor repair	Action(Low)
				Normal injury	L2	Normal repair	Action(Normal)
Severe damage	L3	Severe repair	Action(High)

TABLE 1

Table 1 above shows the damage levels of 4 grades: zero level (L0), first level (L1), second level (L2), and third level (L3). The zero level is no damage, the first level is slight damage, the second level is normal damage and the third level is severe damage, and the damage degrees of the 4 levels correspond to respective repair modes. Here, taking the damage level as L0 as an example, i.e., no damage, the repair policy is no repair required, and the corresponding execution action is no action.

It should be noted that different repair parameters exist for different repair methods, and each repair parameter is smaller in a repair process corresponding to a slight repair, for example, the repair time is shorter. And normal repair is light repair, and corresponding repair parameters are larger. In the heavy repair process, each repair parameter is relatively maximum, and the repair needs to be carried out for a longer time.

Here, the mapping relationship between the damage level and the repair policy may be determined based on various empirical values of the screen in the historical use and repair, that is, the damage degree and the repair parameter of each screen division region in the historical use process of a certain type of screen are counted, and then the mapping relationship between the damage level and the repair policy is determined.

After the damage degree of each screen division area is determined, when the screen division area is further determined to belong to the area to be repaired, the repair grade to which the damage degree belongs can be determined based on the pre-stored mapping relation between the damage grade and the repair strategy, and the corresponding repair strategy is determined based on the corresponding relation between the repair grade and the repair strategy, so that the screen is repaired. The repair grade is the damage grade in table 1.

In some embodiments, the screen repairing the area to be repaired includes:

displaying a repair picture in the area to be repaired;

Here, when a certain area to be repaired is performing screen repair, a repair picture may be displayed in the area to be repaired. The larger the damage degree of the area to be repaired is, the longer the display time of the repair picture displayed on the area to be repaired is when the repair picture is displayed is, and/or the larger the number of display frames is.

Here, when the screen repair is started, the display of the repair screen may be started in the corresponding region to be repaired. And when the screen is repaired, stopping displaying the repair picture.

The repair picture may be any picture, for example, different modification pictures may be set corresponding to different levels of damage, when a certain area to be repaired corresponds to a first level of damage, the repair picture B is displayed on the area to be repaired, and when a certain area to be repaired corresponds to a third level of damage, the repair picture D is displayed on the area to be repaired.

Therefore, the user can directly know the damage degree of the screen according to the repair picture, the repair duration can be further calculated, and the user can conveniently master the repair progress.

The following describes a specific manner of determining the degree of damage of each screen division region:

in some embodiments, the determining the degree of damage of the plurality of screen division regions comprises:

As described above, when the screen is used, the use time period has a direct influence on the damage degree of the screen, and the longer the use time period is, the greater the damage degree of each screen division area is. When the screen division areas are used for the same time, the damage degree of each screen division area can be different due to different brightness of each screen division area in use. According to the embodiment of the disclosure, the damage degree of each screen division region is determined by counting the display brightness and the display time of each screen division region.

In some embodiments, the determining the damage degree of each of the screen division areas according to the display brightness and the display duration includes:

I.e., C ═ B ═ T

In the formula, C is the damage degree, B is the display brightness, and T is the display duration.

Here, since the use of the screen is not continuous, the total damage degree of the screen is determined based on the accumulation of the damage degrees of the multiple uses. Thus, the accumulated value of the damage degrees in multiple uses is used as the total damage degree of the screen. Namely: CN, C1+ C2+ C3+. CN refers to the damage level determined in the Nth initial use of the screen, and N can take the value of 1, 2, 3 ….

For example, taking an a0 area as an example, the screen power-on time (screen-on time) is recorded as t0, the screen is started for the first time at t0, and then the damage value of the a0 area is 0, and after t minutes, that is, the screen is closed at t1(t0+ t), the damage degree C1 of the a0 area may be determined to be B0 × t from t0 to t1 based on the statistical display brightness B0 and the display duration t.

Then, assuming that the screen is started again after t minutes, that is, the screen is started for the second time at the time t2(t0+2t), and the screen is closed again after t minutes, that is, at the time t3(t0+3t), the damage degree C2 of the a0 region at this time is determined to be C1+ B2 × t. B2 is the statistical display brightness of the acquisition period from time t2 to time t 3.

Here, the counting the display luminance of each of the screen division regions includes:

Since the display content executed by the screen after each startup may be different, different display contents may correspond to different brightness in each screen division region. Then, the statistics of the display brightness of each of the screen division regions specifically includes: and counting the average display brightness of each screen division area in the using time length.

The preset acquisition period is as follows: the time period for acquiring the display luminance of the screen is, for example, performed every 1 minute, specifically: taking the area a0 as an example, the power-on time (screen-on time) of the screen is recorded as t0, and the display brightness value of the area a0 is recorded as B0; assuming that the preset acquisition period is t, the display brightness value is acquired once again after t minutes, namely at the time of t1(t0+ t), and is marked as B1, and the display brightness value in the time period from t0 to t1 is (B0+ B1)/2.

Correspondingly, the time from t0 to t1 is an acquisition period, when the display brightness values of the screen are continuously acquired in a plurality of continuous acquisition periods, the acquired display brightness values are accumulated based on the acquired display brightness values, and then the average is calculated, so that the accumulated display brightness values of the divided areas of the screen can be obtained.

For example, taking the a0 area as an example, assuming that the preset acquisition period is t, the screen power-on time (screen-on time) is recorded as t0, and the display brightness value of the a0 area is recorded as B0; then, after t minutes, that is, the display brightness value is collected once again at the time t1(t0+ t) and recorded as B1, and after t minutes, that is, the display brightness value is collected once again at the time t2(t0+2t) and recorded as B2, the display brightness value in the period from t0 to t2 is (B0+ B1+ B2)/3. Thus, the damage degree C of each of the screen division regions is (B0+ B1+ B2)/3 × (2 t).

It should be noted that B0 refers to the display brightness value of the a0 area, and a0 includes a plurality of pixels as one area. Then, in the embodiment of the present disclosure, the display brightness value B0 of the a0 area refers to: and determining an average display brightness value based on the display brightness values of a plurality of pixel points contained in the A0 area.

In the present disclosure, the following embodiments are also provided to determine the degree of damage of a plurality of screen division areas, namely:

acquiring a screen capture image of the preset picture;

In the disclosure, in addition to directly counting the display brightness and the display duration to determine the degree of damage, a comparison with a reference image is also proposed to determine the degree of damage.

After the screen is used for a period of time, each divided area of the screen can be damaged in different degrees, and the display effect when the preset picture is displayed at the moment can be different compared with the display effect when the preset picture is displayed when the screen is not damaged. Then, the damage degree can be determined by comparing the screen capture image with the reference image.

Here, the process of comparing the screen capture image with the reference image to determine the damage degree of each of the screen division regions may be: a preset picture is prepared, the preset picture is displayed in a full screen mode when the screen is not damaged, and screen capture is carried out to obtain a reference image. And when the service time of the screen is longer than the first time threshold, displaying the preset picture on the screen in a full screen mode, and performing screen capture, wherein the captured image is obtained at the moment. And comparing the screen shot image with the reference image to determine the damage degree of each screen division area.

The first duration threshold refers to a threshold at which damage to the screen is expected, and the size of the first duration threshold is related to screen parameters, such as the model of the screen or the durability of the material, and the size of the first duration threshold may be set as needed, which is not limited by the present disclosure.

In some embodiments, the screen usage time is greater than the first time threshold, which may be: the total use time of the screen is greater than a first time threshold; that is, the total usage time from the beginning of the screen to the present is counted, and when the total usage time is greater than the first time threshold, the preset picture is displayed on the screen in a full screen mode.

In other embodiments, the screen usage duration is greater than the first duration threshold, and may be: the service life of the screen after each start is longer than a first time threshold; namely, when the screen is in use, after the screen is opened every time, if the time length for executing display reaches a first time length threshold value, a preset picture is displayed on the screen in a full screen mode.

Here, since the damage of the screen is damage after cumulative use for a plurality of times, as long as the use time of the screen after each start is greater than the first time threshold, the screen may be damaged, and at this time, the damage degree may be determined based on comparing the screenshot image and the reference image in the above embodiment.

In some embodiments, the comparing the screen shot image and the reference image to determine the damage degree of each of the screen division regions includes:

In the embodiment of the present disclosure, the captured image and the reference image are compared to determine the damage degree of each screen division region, which may be by comparing feature values of the captured image and the reference image to determine the damage degree of each screen division region.

In some embodiments, the feature value of the image may be determined based on a grayscale of the image. Namely: calculating gray difference through the gray of each pixel point in the screenshot image and the gray of each pixel point in the reference image, and determining the damage degree of each screen division area according to the gray difference.

Here, table 2 shows the correspondence of the gradation of different screen division regions in the screen shot image and the reference image screen to the degree of damage:

screen partition area	0	1	2	…	N-1
						Reference image	G(A0)	G(A1)	G(A2)	…	G(An-1)
Screenshot image	G(P0)	G(P1)	G(P2)	…	G(Pn-1)
						Degree of damage	M0	M1	M2	…	Mn-1

TABLE 2

Here, based on the parameters in table 2, the degree of damage of each of the screen division regions may be determined as:

Mn＝G(Pn)-G(An)

in the formula, Mn is a damage degree of the screen division region n in the screen shot image, g (pn) is a gray scale corresponding to the screen division region n in the screen shot image, and g (an) is a gray scale corresponding to the screen division region n in the reference image.

Here, since the damage degree of each screen division region is different in actual use of the screen, the damage degree of each screen division region is determined separately, and the damage degree of each portion can be processed to reduce other undamaged portions or avoid damage of organic materials caused by frequent repair of less damaged portions.

In some embodiments, the screen repairing the area to be repaired includes:

The size of the second duration threshold is related to screen parameters, such as the model of the screen or the durability of the material, and the size of the preset duration threshold can be set according to needs, which is not limited by the present disclosure.

In some embodiments, the second duration threshold > the first duration threshold > the preset duration threshold.

In order not to affect the use of the user, the embodiment of the present disclosure may determine whether to perform screen repair by determining whether the total use time of the screen is greater than the second time threshold each time the screen shutdown instruction is received. And if the total use time of the screen is determined to be greater than the second time threshold when the screen shutdown instruction is received, screen repair can be executed, and at the moment, the repair opportunity is better because the user does not use the screen any more.

In some embodiments, the step of counting the screen use duration may be periodically performed in advance, and when the screen shutdown instruction is received, it is determined whether the total screen use duration is greater than the second duration threshold based on the data counted in advance.

Here, when the total usage time period of the screen is less than or equal to the second time period threshold, the shutdown is normally performed. And when the total use time of the screen is greater than the second time threshold, firstly executing screen repair, and executing shutdown after the repair is completed.

It should be noted that, when shutdown is performed after repair is completed, the repair is completed, and the repair includes: repair is successful or repair fails. I.e. after a repair failure, shutdown is performed as well. For example, when the network is suddenly disconnected, the repair termination is detected, and if the termination time reaches a preset time, the repair is considered to fail, and the shutdown is executed.

Thus, redundant waiting caused by repair failure can be reduced through the detection step and the judgment step.

Here, at the time of screen restoration, it is possible to determine which damage level the damage value of the current screen division area corresponds to by extracting the relevant parameters of the plurality of screen division areas, thereby performing the corresponding action. Regarding the correspondence of damage levels to regions, damage values, and actions to perform, see table 3, table 3 shows the relevant parameters of the screen, as shown in table 3:

grade of damage	L0，L1，L2，L3
		Screen partition area	A0，A1，A2....An-1
Damage value	C(A0)，C(A1)，C(A2)....C(An-1)
		Performing an action	Action(none)，action(low)，action(normal)，action(high)

Fig. 3 is a partial implementation code of a screen repairing method according to an embodiment of the present disclosure, where fig. 3(a) is a schematic logic code diagram of screen repairing according to an embodiment of the present disclosure. Fig. 3(b) is another logic code diagram for screen repair in the embodiment of the present disclosure. Fig. 3(c) is a code implementation part for acquiring the gray scales of the screen capture image and the reference image. As shown in fig. 3(c), the gray levels of the screen capture image and the reference image may be acquired based on the getColorGray () function. After obtaining the gray scale, the damage degree can be further determined, and then the screen repair is realized according to the main logic code in fig. 3 (b).

The present disclosure also provides the following embodiments:

before executing the embodiment of the present disclosure, the damage level of the screen and the execution time of screen repair are defined:

for example, the damage of the screen may be defined as 4 levels as shown in table 1 according to the degree of damage of the screen.

For another example, after the screen use time exceeds T minutes, it is determined whether screen repair is required, and after it is determined that screen repair is performed, the repair strategy of the embodiment of the present disclosure is performed to repair.

As shown in fig. 4, fig. 4 is a schematic flowchart illustrating a screen repairing method according to an exemplary embodiment, where the screen repairing method of the present disclosure includes:

step 401, counting the service life of the screen.

And counting the service time T of the screen from the screen lightening on the screen. The flow is as follows:

and after the screen is lightened, the screen is considered to be used, after m minutes, the time is counted once, and the m value is stored in the database.

Namely: T-T0 + m;

t0 is the saved time value in the database, and m minutes is saved on the basis of the saved time value, so that the screen use time length T is obtained.

It should be noted that the use duration here refers to the total use duration of the screen.

Step 402, determining whether the usage duration of the screen is greater than a second duration threshold.

When the usage time of the screen is less than or equal to the second time threshold, go to step 407 directly.

When the usage time of the screen is greater than the second time threshold, go to step 403.

In step 403, the screen is divided into a plurality of screen division areas.

After the screen is highlighted, the screen area may be divided into N areas (for example, 9 areas in total for 3 × 3) according to the screen size, which are respectively denoted as a0, a1, and a2.. a8 areas.

At step 404, the damage level of each screen division area is calculated.

Since the most direct cause of screen damage is brightness, the present disclosure creates brightness for N different areas of the screen, and the sampling devices C (a0), C (a1), C (a2) that use time. The degree of damage of the screen division regions for the period of time is determined based on the product of the average brightness value of each screen division region and the time.

The average brightness value of the screen divided regions is counted every fixed time (e.g., 1 minute), and the shorter the interval time is, the more accurately the damage level is calculated.

For example, taking the a0 area as an example, the specific procedure for calculating the damage degree is as follows:

step 4041, recording the screen-on-screen lighting time as t0, and recording the average brightness value of the current A0 area as B0;

in step 4042, the time after t minutes is denoted as t1, and the current average brightness value of the region is denoted as B1, and then the damage degree C0 of the a0 region in the t time period is denoted as C0 ═ B1+ B0)/2 × t.

Step 4043, store C0 in the database.

Assuming that a part of the damage degree C (a) for the a0 area is stored in the database before, the total screen damage value of the a0 area at this time is C (a0) ═ C (a) + C0;

step 4044, repeat steps 4041 through 4043, and cumulatively record the extent of damage in the area a 0.

The respective damage degrees C (a0), C (a1), C (a 2.) No.. C (An-1) are recorded for all N areas and saved to a database.

Step 405, determine whether screen repair is needed.

Here, it is determined whether or not screen restoration is required for each screen division region according to the degree of damage determined for each screen division region.

And dividing the screen needing screen repair into areas, and executing screen repair corresponding to the action.

In step 406, screen repair is performed.

When it is determined in step 405 that a screen repair action is required, all screen-related parameters are extracted, and for all screen-divided regions, which damage level range the current region damage value meets is determined, so that a corresponding action is performed.

It should be noted that, here, when it is determined that screen repair needs to be performed, the implementation timing of the specific repair action may be: and when a screen shutdown instruction is received.

That is, based on the

above steps

401 and 402, it can be seen that the total usage time of the screen has reached the second time threshold, at this time, the damage degree of each screen division area can be determined, and it is known through the

above steps

403, 404, and 405 that the screen repair is to be started, and then, when the screen shutdown instruction is received, a specific screen repair step can be implemented.

Here, when the

above steps

403, 404, and 405 are executed, the screen is in a use stage, and at this time, performing the repair directly may affect normal use of the user, and then the specific repair step may be performed when the screen shutdown instruction is received.

Specifically, when the screen is powered off, it is first determined whether the total screen use time (T saved in step 401) has reached the limit for performing screen repair (the second duration threshold T2 defined in step 402).

And step 407, ending.

Therefore, because the damage degree of each screen division area is different in the use of the screen in practice, the damage degree of each screen division area is determined respectively, and then the targeted repair is performed, so that the damage of the organic materials caused by frequent repair of other undamaged parts or less damaged parts can be effectively reduced while the screen is repaired.

The present disclosure also provides another embodiment:

before executing the embodiment of the present disclosure, a preset picture P is preset, and the damaged level of the screen and the execution time of screen repair are defined:

As shown in fig. 5, fig. 5 is a fourth flowchart illustrating a screen repairing method according to an exemplary embodiment. The screen repairing method comprises the following steps:

step 501, counting the service life of the screen.

Namely: T-T0 + m;

Step 502, determining whether the service time of the screen is greater than a second time threshold.

When the usage time of the screen is less than or equal to the second time threshold, go to step 507 directly.

When the usage time of the screen is greater than the second time threshold, go to step 503.

Step 503, acquiring the screen capture image and the reference image.

Taking an electronic device as a television as an example, when the television is started and the service life of the screen is determined to be greater than a first time threshold, displaying a preset picture P in a full screen mode, carrying out screenshot, and saving the screenshot as bitmap A. BitmapA was cut into N regions, a0, a1, and a2.

And displaying the preset picture P in a full screen mode when the screen is not damaged, cutting the preset picture P to obtain a reference image, and cutting the reference image into N areas, namely P0, P1 and P2 … Pn-1.

Step 504, comparing the screen capture image with the reference image, and determining the damage degree of each screen division area.

And comparing the characteristic values of the screenshot image and the reference image, wherein the characteristic values of the image can be obtained by adopting a method for obtaining gray levels, namely obtaining the gray level value of each pixel point, adding the gray level values to obtain the integral gray level value, and calculating the damage value Mn.

The damage value M may be calculated using the absolute value of the difference between the two feature values: mn ═ g (pn) -g (an).

And 505, judging whether screen repair is needed or not.

Step 506, screen repair is performed.

When it is determined in step 505 that a screen repairing action is required, all screen-related parameters are extracted, and for all screen division areas, it is determined which damage level range the current area damage value meets, so as to execute a corresponding action.

Here, the detailed description of the implementation timing of the repair action is the same as that of step 406, and is not repeated.

And step 507, ending.

According to the screen repairing method provided by the embodiment of the disclosure, whether each screen division region belongs to a region to be repaired is determined by determining the damage degree corresponding to each of a plurality of screen division regions obtained after screen division, and if the screen division regions belong to the region to be repaired, screen repairing is performed. Therefore, in practice, due to the fact that the damage degree of each screen division area is different in the use of the screen, the damage degree of each screen division area is determined respectively, and the damage degree of each screen division area can be processed according to the different damage degree of each part, so that other undamaged parts are reduced, or the damage of organic materials caused by frequent repair of the less damaged parts is avoided.
