Description

Technical Field

[0001] The present application relates to the technical field of smart terminals, and in particular to a burn-in screen repair method, an electronic device, and a readable storage medium. Background Art

[0002] Organic light-emitting diodes (OLEDs) are diode devices formed by stacking multiple layers of organic nanofilms. In a display screen constructed by OLEDs, each OLED can emit light independently, so that each OLED in the OLED display screen will have different degrees of attenuation during use. Since organic materials age faster than inorganic materials, the burn-in phenomenon of OLED displays is more serious than that of light-emitting diode (LED) displays made of inorganic materials.

[0003] When an OLED display screen displays an image, the conduction current of the OLED in the high-brightness area of ​​the image is greater than the conduction current of the OLED in the low-brightness area. Therefore, when a certain image A is displayed statically for a long time, the OLED in the high-brightness area of ​​image A will age more easily than the OLED in the low-brightness area. Under the same current, the display brightness of the aged OLED is lower than that of the unattenuated OLED. This causes the display screen to display different brightness of OLEDs with different attenuation degrees on the display screen after the display screen ends displaying image A for a long time and changes the display content, such as when displaying a pure color interface, resulting in an afterimage of image A that cannot be eliminated. This is the screen burn-in phenomenon.

[0004] Whether the OLED display screen of an electronic device is prone to screen burn-in is related to the usage scenario of the electronic device. For example, the computer interface has more fixed icon scenes than mobile phones and tablets, with higher average brightness and longer average daily usage time in office scenarios. The application of OLED display screens in the field of computer display will increase the probability of screen burn-in. For another example, the silicon-based OLED display technology includes mixed reality / augmented reality / virtual reality (MR / AR / VR) display technology. The optical path loss of the above display technology is large, and the luminous brightness of OLED needs to be greatly improved to ensure the display effect (for example, it needs to be increased to 5000nits, which is several times the display brightness of mobile phones, tablets, computers and other devices). This causes OLED to decay faster and the probability of screen burn-in is higher. For another example, time-lapse photography requires displaying the same image for a long time with less dynamic changes. Therefore, the display screen of a time-lapse camera using an OLED display screen is prone to screen burn-in. For another example, live broadcast applications usually have fixed icons, and OLEDs that display fixed icons for a long time are prone to decay. Therefore, live broadcast devices using OLED displays are also prone to screen burn-in.

[0005] In addition, in order to provide users with a more realistic display experience, OLED displays usually load high-dynamic range (HDR) display solutions, which will increase the contrast between light and dark on the display and increase the upper and lower limits of brightness. This will further increase the probability of burn-in on OLED displays.

[0006] However, it is extremely difficult to repair a burned-in display, so users can only replace the display, which is very costly. Therefore, how to repair a burned-in OLED display without replacing the display has become an urgent problem to be solved. Summary of the invention

[0007] The embodiments of the present application provide a burn-in screen repair method, an electronic device, and a computer-readable storage medium. By providing a burn-in screen repair software to a user, it is convenient for the user to perform burn-in screen repair. The user can use the burn-in screen repair software to complete the burn-in screen repair immediately.

[0008] Some embodiments of the present application provide a method for repairing screen burn-in. The present application is introduced from multiple aspects below, and the embodiments and beneficial effects of the following aspects can be referenced to each other.

[0009] In a first aspect, the present application proposes a burn-in repair method, which is applied to an electronic device including a display screen, wherein the display screen includes multiple light-emitting elements and a burn-in area, the method including: displaying a first application interface, the first application interface including an adjustment control; detecting a first operation of the adjustment control by a user; determining a first expected display brightness corresponding to the first operation; based on the first expected display brightness, determining an excitation current of the display screen including multiple light-emitting elements, wherein the multiple light-emitting elements include a first light-emitting element and a second light-emitting element, the first light-emitting element is located in the burn-in area, the second light-emitting element is located outside the burn-in area, and the determined first excitation current of the first light-emitting element and the second excitation current of the second light-emitting element are different.

[0010] It can be understood that the first application is the burn-in repair software, which can provide the user with a first application interface (i.e., the burn-in repair interface), in which an adjustment control for adjusting the burn-in repair intensity is provided. By obtaining the user's operation on the adjustment control, the electronic device can generate the first expected display brightness (e.g., the first brightness value L(t)) corresponding to the adjustment control in real time. Since the display brightness of the OLED is linearly related to the excitation current, the excitation current for exciting each OLED in the OLED display screen can be determined according to the first expected display brightness, and the excitation current corresponding to each OLED is used to excite each OLED respectively. So that the display brightness of the OLED in the OLED display screen changes, that is, the user can observe that the brightness of the first light-emitting element in the non-burn-in area and the second light-emitting element in the burn-in area changes (e.g., both become brighter) during the process of adjusting the adjustment control, which changes the brightness of the entire OLED display screen. When the user observes that the brightness of the display area where the burn-in occurs is the same as the brightness of the display area where the burn-in occurs during the process of adjusting the adjustment control, the burn-in repair is completed. This avoids the need to use special equipment to shoot the display screen to analyze the burn-in area, and the user does not need to go to the repair site with special equipment. The burn-in repair can be done anytime, anywhere, and is convenient to use.

[0011] It is understood that the initial excitation current of the first light-emitting element and the second light-emitting element may be the same, for example, the rated operating current of the display screen. After the electronic device detects the user's first operation on the adjustment control, the excitation current of the first light-emitting element and the second light-emitting element changes, for example, the excitation current of the first light-emitting element in the non-burned screen area is less than the excitation current of the second light-emitting element in the burned screen area, so that the display brightness of the first light-emitting element and the second light-emitting element tends to be consistent.

[0012] In a possible implementation of the first aspect above, the first application interface includes a background layer, wherein the background layer includes any one of a white background layer, a red background layer, a green background layer, or a blue background layer.

[0013] That is, the first application interface may be covered with a background layer, such as a white layer, a red layer, a green layer or a blue layer, or a single grayscale layer, a multi-level grayscale layer or any other image layer, and the above background layer can be freely set by the user. It can be understood that through the above background layer, the light and dark contrast of the burn-in area can be improved, the burn-in area can be highlighted, and the user can determine the burn-in repair effect in real time with the naked eye. This allows users to see the burn-in area and the burn-in repair effect with the naked eye alone, and the brightness analysis device is no longer a necessary device for burn-in repair. Furthermore, the burn-in repair location can be a designated repair location with a brightness analysis device, or it can be the user's home. The repair location is no longer restricted by the brightness analysis device, making it convenient to repair the burn-in screen. It can be understood that the layer composed of the above picture background is located under the icon layer corresponding to the adjustment control. Since the adjustment control is movable, it will not block the burn-in area highlighted by the background of the displayed picture.

[0014] In a possible implementation of the first aspect, determining the first expected display brightness corresponding to the first operation includes: inputting the first repair strength value corresponding to the first operation into the first model to determine the first expected display brightness. It can be understood that the first operation is the user's adjustment operation on the adjustment control, and the electronic device can determine the first repair strength value corresponding to the first operation, and then determine the first expected display brightness according to the first repair strength value, so that the display brightness area of ​​all OLEDs has the first expected display brightness, until the first expected display brightness is adjusted to the first brightness value, so that the OLED at any use time tends to the first brightness value, and the burn-in phenomenon is repaired.

[0015] In some embodiments, the first model may be a lifetime model. For example, a stretched exponential decay (SED) model may be used as the lifetime model. The SED model may be used to derive a decay equivalent curve of an OLED.

[0016] The model can be represented by the following formula (1.1), formula (1.2) and formula (1.3):

[0017]

[0018]

[0019]

[0020] Where n is the acceleration factor related to the decay rate, which is an empirical value and is affected by factors such as the brightness of the light-emitting device, temperature, and packaging effect;

[0021] L (t)is the display brightness value of the display unit at time t; L0 is the initial brightness of the display unit;

[0022] t 1 / 2 is the half-life of OLED, i.e., the time it takes for the display brightness of OLED to decay to 50% of the original display brightness;

[0023] τ, β, C, and K are all constant parameters of the life of OLED, which are related to the OLED material, device structure, and manufacturing process. For example, they are related to the structure of the light-emitting material, the arrangement of the light-emitting units, the arrangement density, and the packaging structure. The values ​​can be determined by curve fitting.

[0024] In a possible implementation of the first aspect above, the first repair intensity value includes any one of the following items: an acceleration factor related to the decay rate of the light-emitting element, and multiple constant parameters related to the life of the light-emitting element, wherein at least two of the acceleration factor related to the decay rate of the light-emitting element and the multiple constant parameters related to the life of the light-emitting element have a first corresponding relationship, wherein the first corresponding relationship includes a linear relationship.

[0025] It can be understood that the parameters that affect the display brightness value of the display unit at time t include at least the following five parameters:

[0026] (1) n: acceleration factor related to the display brightness decay rate;

[0027] (2)τ: specific decay time scale;

[0028] (3) C: constant parameters determined by OLED materials, device structure and manufacturing process;

[0029] (4) β: constant parameter determined by OLED materials, device structure and manufacturing process;

[0030] (5) K: A constant parameter determined by OLED materials, device structure and manufacturing process.

[0031] Therefore, the display brightness of a single display unit during the current use time can be adjusted by adjusting any one or more of the above five parameters, for example, any one of n, τ, C, β or K. For example, the display brightness of a single display unit during the current use time can be increased to a first brightness value, so that all display units of the display screen have a uniform display brightness and screen burn-in is corrected.

[0032] In a possible implementation of the first aspect above, the adjustment control includes a control bar, a control panel, a control icon, or a physical button.

[0033] It can be understood that the adjustment control can have various forms, such as a control bar, a control panel, a control icon or a physical button, and the adjustment control can be moved within the first application interface to avoid blocking the burn-in area.

[0034] In some embodiments, by constructing the adjustment control in the form of a control bar, the repair strength value can be quickly adjusted to achieve rapid repair of the burn-in screen.

[0035] In other embodiments, by constructing the adjustment control in the form of a control dial, the control dial can have multiple gears, so that the user can accurately adjust the repair intensity value in multiple gears, and then accurately adjust the display brightness of the OLED by accurately adjusting the relevant parameters of the life model, thereby improving the accuracy of burn-in repair.

[0036] In some other embodiments, the adjustment control may also be a plurality of grouped icons, such as an increase control and a decrease control, where the increase control may be represented by a "+" icon and the decrease control may be represented by a "-" icon. The adjustment value of the first repair intensity value by a single click of the user to increase the control and a single click of the decrease control may be set. In some implementations, the adjustment value of the first repair intensity value by a single click of the adjustment control is set to be lower than a specified value, so that the user can make a small and precise adjustment to the first brightness value, thereby achieving precise repair of the burn-in screen.

[0037] In a possible implementation of the first aspect above, the value range of the first expected display brightness includes 0 to 10000 nits.

[0038] It can be understood that the value range of the first desired display brightness can be 0 to 10,000 nits, as long as the display brightness of all OLEDs on the screen can be made consistent.

[0039] In some embodiments, the first desired display brightness may be 600 nits.

[0040] In a possible implementation of the first aspect above, the first application interface includes a recovery control, and the method further includes: detecting a second operation of the user on the recovery control; and restoring the brightness of the display screen to the brightness before the user adjusted the control.

[0041] It can be understood that when the life model parameters are changed, in order to avoid damage to the display unit of the display screen caused by incorrect parameter modifications, a recovery control can be set on the first application interface. The recovery control is used to restore the first repair intensity value to the initial repair intensity value, providing an entry for the user to restore the initial parameter value of the life model. Furthermore, after the first repair intensity value is restored to the initial repair intensity value, the brightness of the display screen can be restored to the brightness before the user adjusted the first adjustment control. In a possible implementation of the first aspect above, the brightness of the display screen is restored to the initial brightness before the user adjusted the adjustment control, including: obtaining the initial repair intensity value of the first model, inputting the initial repair intensity value into the first model, and obtaining the initial brightness.

[0042] It can be understood that by inputting the initial repair strength value into the first model, the initial brightness can be obtained, thereby ensuring that the brightness of the display screen can be restored to the level before the user adjusted the first adjustment control.

[0043] In some embodiments, the initial numerical parameters of the life model may be pre-stored in the memory of the electronic device and may be stored in a preset format. For example, the initial parameters of the life model may be written into a display configuration file or into a display log file.

[0044] In a possible implementation of the first aspect above, the initial repair intensity value is input into the first model to obtain the initial brightness, including: inputting the initial repair intensity value into the first model to obtain the second expected brightness; determining the excitation current of each light-emitting element corresponding to the second expected brightness according to the second expected brightness, and using the excitation current of each light-emitting element corresponding to the second expected brightness to excite the light-emitting element to obtain the initial brightness.

[0045] It can be understood that after the initial repair intensity value is input into the first model, the second expected brightness can be calculated. The second expected brightness is linearly related to the excitation current. Therefore, the corresponding excitation current of each light-emitting element can be obtained based on the second expected brightness. By exciting each light-emitting element with the excitation current, the light-emitting element can display the initial brightness.

[0046] In a second aspect, the present application also provides an electronic device, comprising: one or more processors; one or more memories; one or more memories storing one or more programs, and when one or more programs are executed by one or more processors, the electronic device executes any possible burn-in repair method of the first aspect mentioned above.

[0047] In a third aspect, the present application further provides a computer-readable storage medium having instructions stored thereon, and when the instructions are executed on a computer, the computer executes any possible burn-in repair method of the first aspect.

[0048] In a fourth aspect, an embodiment of the present application discloses a computer program product comprising instructions, which, when executed on a computer, enables the computer to execute any possible burn-in repair method of the first aspect described above.

[0063] The illustrative embodiments of the present application include, but are not limited to, a burn-in repair method, an electronic device, and a computer-readable storage medium.

[0064] In order to facilitate those skilled in the art to understand the solutions in the embodiments of the present application, some concepts and terms involved in the embodiments of the present application are explained below.

[0065] (1) Organic light-emitting diode display (OLED Display): OLED display is a display that uses OLED as the light-emitting element. The display principle of OLED display is to drive each OLED through a power supply. The brightness or intensity of the light emitted by OLED depends on the performance of the light-emitting material and the magnitude of the applied current. For the same OLED, the greater the current, the higher the brightness of the light, and its excitation current is linearly related to the brightness emitted. Therefore, the brightness and grayscale of the OLED display can be adjusted by the DC current of the sub-display units corresponding to the three color channels of red (red, R), green (green, G) and blue (blue, B).

[0066] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0067] The illustrative embodiments of the present application include, but are not limited to, a burn-in repair method, an electronic device, and a computer-readable storage medium.

[0068] Figure 1A and Figure 1B A schematic diagram of a screen burn-in scenario is shown.

[0069] like Figure 1A As shown, when a certain application is started, the mobile phone 00 displays an interface 01, and function controls 01a, 01b and 01c are set in the interface 01, which can be used to obtain the user's interactive request for the interface 01. For example, the user's click operation on 01a can be obtained, and then the mobile phone 00 obtains the user's collection request for the interface 01; the user's click operation on 01b can be obtained, and then the mobile phone 00 obtains the user's comment call request for the interface 01; the user's click operation on 01c can be obtained, and then the mobile phone 00 obtains the user's praise request for the interface 01.

[0070] When mobile phone 00 stays on interface 01 for a long time, the display brightness of interface 01 except for the above-mentioned controls 01a, 01b and 01c is low (for example, black), and the display brightness of controls 01a, 01b and 01c is high (for example, pure white). The display units of display controls 01a, 01b and 01c conduct large current, which causes aging of organic light-emitting materials, triggering brightness decay, and ultimately leading to screen burn-in.

[0071] After the screen burn-in occurs, you can refer to Figure 1B When the mobile phone 00 enters the interface 02 which is different from the interface 01, the interface 02 displays afterimages 02a, 02b and 02c. It can be understood that the afterimage 02a is the brightness attenuation display area of ​​the display area of ​​the control 01a, the afterimage 02b corresponds to the brightness attenuation display area of ​​the display area of ​​the control 01b, and the afterimage 02c corresponds to the brightness attenuation display area of ​​the display area of ​​the control 01c. At this time, no matter what content is displayed in the interface 02, the brightness of the above afterimages 02a, 02b and 02c will always be lower than that of the surrounding areas, thereby affecting the display of the interface 02. Therefore, the screen burn-in phenomenon will seriously affect the user experience.

[0072] Currently, if users want to repair devices with burn-in screens, they need to take them to professional display screen repair sites for burn-in repair. For example, it is necessary to use special equipment (such as an imaging brightness meter) to shoot the burn-in electronic device display screen to obtain the burn-in display screen image, and analyze the burn-in display screen image to obtain the burn-in area. Then professionals will increase the brightness of the burn-in area to repair the burn-in screen. Therefore, it is inconvenient for users to repair the burn-in screen.

[0073] In addition, the above process of determining the burned-in area is very time-consuming. For example, special equipment is required to analyze the grayscale value of each pixel of the burned-in display screen image, which makes the analysis time-consuming. In addition, some burned-in areas do not have clear boundaries. For example, the objects of time-lapse photography usually have small dynamic changes, which makes the boundaries of the burned-in area blurred. Even if special equipment is used to shoot the burned-in display screen, it is still difficult to analyze the accurate burned-in area. Even if special equipment is used, the burn-in repair effect is not accurate.

[0074] Therefore, in order to solve the above problems, the present application proposes a burn-in screen repair method, which facilitates users to perform burn-in screen repair by providing users with a burn-in screen repair software. Users can use the burn-in screen repair software to complete the burn-in screen repair immediately. Specifically, the burn-in screen repair software can provide users with a repair interface, and the repair interface is provided with an adjustment control for adjusting the burn-in screen repair intensity. By obtaining the user's operation on the adjustment control, the electronic device can generate a burn-in screen repair intensity value corresponding to the adjustment control in real time, and determine the excitation current for stimulating each OLED in the OLED display screen based on the burn-in screen repair intensity value, and use the excitation current corresponding to each OLED to excite each OLED respectively, so that the luminous brightness of the OLED in the OLED display screen changes, that is, the user can observe the brightness change of the entire OLED display screen during the process of adjusting the adjustment control. When the user observes that the brightness of the display area where the burn-in occurs is the same as the brightness of the display area where the burn-in does not occur during the process of adjusting the adjustment control, the burn-in screen repair is completed.

[0075] It can be understood that different display brightness values ​​can be set corresponding to different burn-in repair intensity values. For example, when the user adjusts the adjustment control to the first repair intensity value, it means that the display brightness needs to be adjusted to the first brightness value. Due to the burn-in phenomenon, the brightness of the OLED in the burn-in area and the OLED in the non-burn-in area are different. Therefore, the electronic device can set different excitation currents for OLEDs with different brightnesses to make the brightness of the entire display screen tend to the first brightness value.

[0076] Specifically, the above-mentioned burn-in repair software is set in an electronic device including a display screen, and is used to repair the display screen of the electronic device. When the electronic device detects that the user starts the burn-in repair software, the burn-in repair software is called to provide a repair interface for the user, and the repair interface is provided with an adjustment control for adjusting the burn-in repair intensity. It can be understood that when the electronic device detects that the user adjusts the adjustment control, the adjusted burn-in repair intensity value can be determined, and the electronic device can adjust the OLED brightness based on the adjusted burn-in repair intensity value.

[0077] Therefore, in some embodiments of the present application, a life model can be used to determine the brightness of the OLED under different burn-in repair intensity values, and the model parameters of the life model can be related to the burn-in repair intensity value, and then the corresponding excitation current can be determined based on the brightness of the adjusted OLED. For example, the burn-in repair intensity value can be input into the life model to obtain the brightness value of the OLED at the current use time. Since the display brightness and excitation current of the OLED have a linear relationship, the corresponding excitation current can be determined by determining the display brightness of the organic light-emitting diode. Therefore, the electronic device learns the display brightness required by the OLED and can obtain the excitation current values ​​of all OLEDs in the entire display screen. Therefore, in the process of repairing the burn-in area, the user can continuously observe the real-time repair effect of the burn-in area in real time. The visualization of the burn-in repair can shorten the time-consuming burn-in repair, and there is no need for special equipment to shoot the burn-in display screen, and there is no need to analyze the burn-in area to complete the burn-in repair, which is convenient to use.

[0078] In some embodiments, the OLED on the display screen can be divided into multiple display units, and the display unit can include a preset number of organic light-emitting diodes. For example, a single display unit can include one organic light-emitting diode, or two or more organic light-emitting diodes, without limitation. For example, A*B organic light-emitting diodes can constitute a display unit, such as 1*1, 2*2, 3*3, 4*4, 2*4, 3*5, and the excitation current is determined independently for each display unit. Furthermore, the excitation current of a preset number of organic light-emitting diodes can be directly calculated instead of the excitation current of a single OLED, thereby reducing the amount of data calculation and making burn-in repair more efficient.

[0079] For example, the display brightness of a single display unit can be adjusted by adjusting the parameters in the life model of each display unit. For example, the display brightness of a single display unit during the current use time can be increased to a first brightness value, so that all display units of the display screen have a uniform display brightness and screen burn-in is repaired.

[0080] It can be understood that if the adjusted lifespan model is used to control the light emission of a single display unit, the single display unit will display the first brightness value regardless of how long it has been used. Furthermore, after a long period of use, the adjusted lifespan model will compensate the current for display units of different usage times accordingly, so that all display units display the first brightness value. Therefore, after using the above lifespan model to repair the burn-in, it is not easy to cause the burn-in phenomenon again.

[0081] It can be understood that the electronic devices to which the above-mentioned burn-in screen repair method provided in the embodiments of the present application is applicable may include but are not limited to mobile phones, foldable screen mobile phones, tablet computers, desktops, laptops, handheld computers, netbooks, and augmented reality (AR) / virtual reality (VR) devices, smart TVs, smart watches, car displays and other electronic devices with display screens.

[0082] The following is a detailed description of the repair interface for implementing burn-in repair by adjusting the life model parameters in conjunction with the relevant drawings.

[0083] FIG. 2A to FIG. 2B According to some embodiments of the present application, a schematic diagram of an interface for screen burn-in repair is shown.

[0084] refer to Figure 2A , the electronic device 100 is screen-burned, and the screen-burned area 011 appears when the display interface 201 is displayed. At this time, the electronic device 100 can detect the user's operation 202 on the volume key 203, and in response to the operation 202, adjust the specified parameters in the life model of each display unit of the display interface 201 to obtain a first brightness value, so that the display brightness of all display units on the display screen tends to the first brightness value, and obtain Figure 2B An interface 204 of uniform brightness is shown.

[0085] It can be understood that the volume key 203 has a volume increase button and a volume decrease button, and operation 202 can be clicking the volume increase button or clicking the volume decrease button. Thus, clicking the volume increase button can adjust the life model parameters to increase the burn-in repair strength, and clicking the volume decrease button can adjust the life model parameters to reduce the burn-in repair strength. In some embodiments, a single click to adjust the value of the life model can be set. For example, each click of the volume increase button can increase the brightness of the display unit with burn-in in the life model by 2nit until the brightness of all display units with the same usage time is uniform. Since the adjustment value generated by a single click is small, the burn-in repair strength can be accurately adjusted, which facilitates the rapid and accurate repair of the burn-in.

[0086] It is understood that the above operation 202 can be performed by Figure 2A and Figure 2B The physical button implementation shown can also be implemented by virtual controls. Therefore, an adjustment control that can control the life model parameters can be set on the burn-in repair interface. The adjustment control can be used to adjust the parameters of the life model of each display unit, and the adjustment control can be moved arbitrarily on the interface to avoid blocking the burn-in area.

[0087] Combine the following Figure 3 , Figure 4 and Figure 5The above adjustment controls are introduced in detail.

[0088] refer to Figure 3 , the adjustment control may be a control bar 301, which may be moved arbitrarily on the interface 201 to avoid blocking the burn-in area 011. In some embodiments, the user may drag the control bar 301 to adjust the repair strength, for example, to obtain a first repair strength value, and input the first repair strength value into the life model to adjust the relevant parameters of the life model and determine the first brightness value. For example, when the user drags the control bar 301 to the right, the burn-in repair strength may be increased, thereby increasing the first brightness value. The display brightness of each display unit with different usage time is increased to the first brightness value, so that the display brightness of the display screen tends to the first brightness value, and then the first brightness value may be obtained. Figure 2B The uniform brightness interface 204 is shown. By constructing the adjustment control in the form of a control bar, the repair strength value can be quickly adjusted to achieve rapid repair of the burn-in screen.

[0089] refer to Figure 4 , the adjustment control may be a control panel 401, which may be moved arbitrarily on the interface 201 to avoid blocking the burn-in area 011. In some embodiments, the user may rotate the control panel 401 to adjust the repair strength, for example, to obtain a first repair strength value, and input the first repair strength value into the life model to adjust the relevant parameters of the life model, to obtain a first brightness value, and then to make the display brightness of each display unit approach the first brightness value. For example, when the user rotates the control panel 401 in a clockwise direction, it may indicate an increase in the burn-in repair strength, to increase the first brightness value, and to make the display brightness of the display approach the first brightness value. Then, it may be obtained Figure 2B An interface 204 of uniform brightness is shown.

[0090] In some embodiments, the control panel 401 may have multiple gears. Figure 4 As shown, the control panel 401 may have X1 gear, X2 gear, X3 gear, X4 gear, X5 gear, X6 gear, X7 gear and X8 gear, which are respectively used to represent different burn-in repair strengths. Therefore, by constructing the adjustment control in the form of a control panel, the repair strength value can be accurately adjusted in multiple gears, and then the first brightness value can be accurately adjusted by accurately adjusting the relevant parameters of the life model, and the display brightness of the display screen tends to the first brightness value. The accuracy of burn-in repair is improved.

[0091] In some implementations, the adjustment controls may also be a plurality of icons in a group. The following describes the plurality of adjustment controls in conjunction with the relevant drawings.

[0092] refer to Figure 5, the adjustment control may include an increase control 501 and a decrease control 502, and the increase control 501 is represented by a "+" icon, and the decrease control 502 is represented by a "-" icon. And the above icons can be moved arbitrarily on the interface 201 to avoid blocking the burn-in area 011. Here, the user can click the increase control 501 and the decrease control 502 to adjust the repair intensity value, for example, adjust it to a first repair intensity value. The first repair intensity value is a parameter in the life model, and then the first repair intensity value is input into the life model to determine the first brightness value, so that the display brightness of all OLEDs on the display screen tends to the first brightness value. For example, when the user clicks the increase control 501 or the decrease control 502, the first repair intensity value is adjusted in real time. For example, the increase control 501 represents the adjustment of the life model parameters to increase the repair intensity, and the decrease control 502 represents the adjustment of the life model parameters to reduce the repair intensity. Then it can be obtained Figure 2B An interface 204 of uniform brightness is shown.

[0093] Furthermore, the adjustment value of the first repair intensity value by the user's single click increase control and single click decrease control can be set. In some embodiments, the adjustment value of the first repair intensity value by the single click adjustment control is set to be lower than the specified value, so that the user can make a small and precise adjustment to the first brightness value, thereby achieving accurate repair of the burn-in screen.

[0094] Based on the above Figure 2A , Figure 3 , Figure 4 and Figure 5 It can be known that the electronic device 100 can determine the first repair strength value adjusted by the user by adjusting the control or physical button, and then input the first repair strength value into the life model to obtain the first brightness value. The excitation current of each display unit is determined according to the first brightness value and the use time of each display unit, so that the display brightness of each display unit on the interface is consistent.

[0095] For example, before the repair intensity is adjusted, each display unit uses the rated current to excite and emit light, and each display unit will reduce the display brightness as the usage time increases. Therefore, different display units have different display brightnesses due to different usage times. After adjusting the repair intensity, the display brightness of all display units needs to be adjusted to the first brightness value. Therefore, based on the first brightness value and the current brightness value corresponding to the rated excitation current at different usage times, the brightness difference that needs to be improved for different display units can be determined, and then the current difference that needs to be compensated for the current current value can be determined, and different excitation currents can be formulated for display units at different usage times. So that the display brightness of each display unit on the interface is the first brightness value.

[0096] It is understood that the above-mentioned setting methods of adjustment controls and physical buttons are examples. For example, the adjustment controls can be called up on the burn-in repair interface in other ways, such as the user can use a preset gesture (such as tapping the mobile phone / tablet display, or starting a spatial gesture during the use of MR / AR / VR devices) to call up the adjustment controls from the burn-in repair interface, and no specific limitation is made here.

[0097] Based on the above Figures 2A to 5 The repair interface schematic diagram is shown, and the specific implementation process of a burn-in screen repair method provided by the present application is described in detail below in combination with specific embodiments and related drawings.

[0098] Figure 6 According to some embodiments of the present application, a schematic diagram of a burn-in screen repair method is shown. It can be understood that Figure 6 The execution entity of each step of the illustrated process may be the electronic device 100 described above, or other electronic devices, and the execution entity of a single step will not be described in detail.

[0099] like Figure 6 As shown, the interaction process includes the following steps:

[0100] 601 , detecting a user start operation of starting a burn-in screen repair application.

[0101] It can be understood that the above-mentioned user startup operation can be a click operation on the burn-in screen repair application icon, etc. When the electronic device detects the user startup operation, it can call the burn-in screen repair application in response to the user startup operation.

[0102] 602 , in response to a user start operation, loading a burn-in screen repair interface.

[0103] It can be understood that in response to the user's startup operation, a burn-in screen repair interface, such as a solid color interface, can be loaded to facilitate the user to observe the real-time burn-in screen repair effect with the naked eye.

[0104] In some embodiments, the above-mentioned burn-in repair interface may be covered with a background layer, such as a white layer, a red layer, a green layer or a blue layer, or a single grayscale layer, a multi-level grayscale layer or any other image layer. It can be understood that through the above-mentioned background layer, the light-dark contrast of the burn-in area can be improved, and the burn-in area can be highlighted, so that the user can determine the burn-in repair effect in real time with the naked eye. For example, when the organic light-emitting diode displaying blue is severely aged, the burn-in area is not obvious in the white layer, the red layer and the green layer, and the burn-in area in the blue layer will be very dark, and the brightness difference with the surrounding non-burn-in area is large, which is convenient for users to distinguish the burn-in area and determine the real-time repair effect of the burn-in. This allows users to see the burn-in area and the burn-in repair effect with the naked eye, and the brightness analysis device is no longer a necessary device for burn-in repair. Furthermore, the burn-in repair location can be a designated repair location with a brightness analysis device, or it can be the user's home. The repair location is no longer restricted by the brightness analysis device, making it convenient to repair the burn-in screen.

[0105] It can be understood that the layer formed by the above-mentioned picture background is located under the icon layer corresponding to the adjustment control. Since the adjustment control is movable, it will not block the burn-in area highlighted by the display picture background.

[0106] The following is a detailed description of the background of the burn-in repair interface mentioned above in conjunction with the relevant drawings.

[0107] Figure 7 The burn-in screen repair interface for obtaining user repair operations through the control bar 301 is illustrated. Figure 8 The burn-in screen repair interface for obtaining user repair operations through the control panel 401 is illustrated. Fig. 9 The burn-in screen repair interface for obtaining user repair operations through control icon 501 and control icon 502 is illustrated. Fig.10 The burn-in screen repair interface for obtaining a user repair operation through the volume key 203 is illustrated.

[0108] It can be understood that when the burn-in repair is started, a burn-in repair interface can be provided to the user, so that the user can perform the burn-in repair through any control set on the burn-in repair interface or a physical button of the electronic device 100. In order to accurately display the burn-in area, solid color pictures of different colors can be preset as the background of the burn-in repair interface, and gradient pictures of different grayscales can also be preset as the background of the burn-in repair interface.

[0109] For example, reference Figures 7 to 10 , which presents a burn-in screen repair interface for loading different controls or physical buttons, and is equipped with four solid color images of white, red, green and blue as the background layer of the burn-in screen repair interface. The burn-in screen area 702 can be displayed more clearly through the interface background of the above four colors, so that the user can observe the repair effect in real time with the naked eye.

[0110] For example, refer to Figures 7 to 10 , the burn-in repair interfaces 701W, 801W, 901W and 1001W all use a white pure color picture as the background, the burn-in repair interfaces 701R, 801R, 901R and 1001R use a red pure color picture as the background layer, the burn-in repair interfaces 701G, 801G, 901G and 1001G use a green pure color picture as the background layer, and the burn-in repair interfaces 701B, 801B, 901B and 1001B use a blue pure color picture as the background layer. The above-mentioned pure color pictures of different colors are used as the background layer of the burn-in repair interface. After the burn-in area 702 is repaired, a pure color layer background without residual image can be obtained for the user to confirm the burn-in repair effect. For example, after the burn-in repair interfaces 701W, 801W, 901W and 1001W are repaired, a white layer background 701W', 801W', 901W', 1001W' without residual image can be obtained. For another example, after the burn-in repair interface 701R, 801R, 901R and 1001R is repaired, a red layer background 701R', 801R', 901R', 1001R' without residual image can be obtained. For another example, after the burn-in repair interface 701G, 801G, 901G and 1001G is repaired, a green layer background 701G', 801G', 901G' and 1001G' without residual image can be obtained. For another example, after the burn-in repair interface 701B, 801B, 901B and 1001B is repaired, a blue layer background 701B', 801B', 901B' and 1001B' without residual image can be obtained.

[0111] In some embodiments, in response to the user's startup operation, the electronic device 100 can load the burn-in screen repair interface with a white background layer by default. When the electronic device 100 obtains the user's modification operation on the repair interface background, the user-specified picture can be used as the background layer of the burn-in screen repair interface, for example Figures 7 to 10 The example red, green and blue solid color images are used as the background layer of the burn-in repair interface.

[0112] It can be understood that since the burn-in repair is to increase or decrease the repair intensity of the display brightness by adjusting the parameters of the life model, obtain the first brightness value, and provide corresponding current compensation for all display units with different usage times based on the first brightness value to increase the display brightness of all display units until the first brightness value is reached, there is no need to determine the specific boundary position of the burn-in area. Therefore, pure color pictures of different colors can be loaded as the background layer of the burn-in repair interface without affecting the judgment of the burn-in area.

[0113] In some embodiments, a brightness analysis device may be used to obtain the display brightness of the display screen in real time. For example, an imaging brightness meter may be used to obtain the display brightness of the burned-in area in real time. Once the display brightness is determined to be the first brightness value, the burned-in repair may be completed.

[0114] Furthermore, it can be understood that if only a brightness analysis device is used to capture the image displayed on the display screen and the pixel grayscale in the image is analyzed to determine the burn-in area, for burn-in situations without clear boundaries, the burn-in area may be misjudged, resulting in the inability to repair the burn-in area boundary. In the present application, since current compensation can be performed on each display unit based on the life model until all display units have the same display brightness, the burn-in area without clear boundaries can be accurately repaired.

[0115] 603, obtaining the user's adjustment operation on the adjustment control on the burn-in screen repair interface.

[0116] It can be understood that the adjustment operation can be an interactive operation of the user on the burn-in screen repair interface, such as the user dragging a control bar, rotating a control dial, or clicking a control icon.

[0117] In other embodiments, the above-mentioned adjustment control may also be associated with a physical button, so that the repair strength value can be directly adjusted by obtaining the user's touch operation on the physical button.

[0118] It can be understood that the specific examples of the above adjustment operations can be referred to above. Figures 2A to 5 The user operations shown are not further described here.

[0119] 604 , determine a first repair strength value based on the adjustment operation.

[0120] It can be understood that in response to the user's adjustment operation, the repair intensity value corresponding to the adjustment operation can be determined, and then the display brightness of all OLEDs can be adjusted according to the repair intensity value, so that the OLEDs at any usage time show the same brightness.

[0121] 605 , input the first repair strength value into the lifespan model to determine a first brightness value.

[0122] It can be understood that different display brightness values ​​can be set corresponding to different burn-in repair intensity values. For example, when the user adjusts the adjustment control to the first repair intensity value, it means that the display brightness needs to be adjusted to the first brightness value. Due to the burn-in phenomenon, the brightness of the OLED in the burn-in area and the OLED in the non-burn-in area are different. Therefore, the electronic device can set different excitation currents for OLEDs with different brightnesses to make the brightness of the entire display screen tend to the first brightness value.

[0123] In some embodiments, the stretched exponential decay (SED) model can be used as a lifetime model for each display unit, and the SED model can derive an equivalent decay curve of the OLED. The model can be represented by the following formulas (1.1), (1.2) and (1.3):

[0124]

[0125]

[0126]

[0127] Where n is the acceleration factor related to the decay rate, which is an empirical value and is affected by factors such as the brightness of the light-emitting device, temperature, and packaging effect;

[0128] L (t) is the display brightness value of the display unit at time t; L0 is the initial brightness of the display unit;

[0129] t 1 / 2 is the half-life of OLED, i.e., the time it takes for the display brightness of OLED to decay to 50% of the original display brightness;

[0130] τ, β, C, and K are all constant parameters of the life of OLED, which are related to the OLED material, device structure, and manufacturing process. For example, they are related to the structure of the light-emitting material, the arrangement of the light-emitting units, the arrangement density, and the packaging structure. The values ​​can be determined by curve fitting.

[0131] It can be understood that OLED products produced in the same batch have the same materials, structures and processes, and therefore have similar n, β, τ, C, and K values, and there is a mathematical correspondence between n, β, τ, C, and K between different OLED products in the same batch.

[0132] It can be seen that the parameters that affect the display brightness value of the display unit at time t include at least the following five parameters:

[0133] (1) n: acceleration factor related to the display brightness decay rate;

[0134] (2)τ: specific decay time scale;

[0135] (3) C: constant parameters determined by OLED materials, device structure and manufacturing process;

[0136] (4) β: constant parameter determined by OLED materials, device structure and manufacturing process;

[0137] (5) K: A constant parameter determined by OLED materials, device structure and manufacturing process.

[0138] Therefore, by adjusting any one or more of the five parameters in formula (1.1), for example, any one of n, τ, C, β or K, the display brightness of a single display unit during the current use time can be adjusted. For example, the display brightness of a single display unit during the current use time can be increased to a first brightness value, so that all display units of the display screen have a uniform display brightness, thereby fixing screen burn-in.

[0139] Exemplarily, the first repair intensity value may be any one of the five parameters of the lifespan model to determine the first brightness value required to repair the burn-in screen.

[0140] In other embodiments, one or more of the five parameters may have a corresponding relationship, so that the adjustment control has a corresponding relationship with only a single parameter of the five parameters, for example, any one of n, τ, C, β or K. In this case, in response to the user's repair operation, only a single parameter of the five parameters needs to be adjusted to obtain the updated values ​​of the remaining parameters, which is conducive to the rapid adjustment of the life model and the efficient repair of the burn-in.

[0141] For example, in OLED displays manufactured in batches under the same design, such as the arrangement of OLEDs, the material system of the light-emitting materials in OLEDs, and the process design of the display (such as the packaging process), the values ​​of β and τ mentioned above can have a corresponding relationship. Then, only one of β and τ needs to be adjusted to obtain the updated value of the other parameter, and then the updated brightness L at the current time t can be quickly obtained based on the above formulas (1.1), (1.2), and (1.3). (t) , and make the brightness of all display units at any time t L (t) They are all the same first brightness value.

[0142] In some embodiments, when the repair strength is not adjusted, the lifespan model may be a curve showing the brightness decay of the OLED over time at a rated current. Fig.11 The schematic diagram of multiple display brightness curves of the display unit shown in FIG. 1 , wherein the vertical axis is the brightness L at time t (t) , in nits, and the horizontal axis is the usage time t, in hours (hour, H). Fig.11The display brightness of the display unit without adjusting the repair strength is shown as curve X, which decreases as the use time increases. After adjusting the repair strength until the burn-in phenomenon is fixed, the display brightness of the display unit is shown as straight line Y, which is the first brightness value of 600nit at any use time, so that the brightness of the entire display screen tends to the first brightness value, thereby fixing the burn-in phenomenon.

[0143] In other embodiments, when the repair strength is not adjusted, the initial repair strength value in the life model may also be a specified value, so that the life model can pre-compensate part of the current for the display unit of the entire display screen, delaying the display screen from burning. Fig.11 The brightness and usage time of the life model of the pre-compensation partial current are shown in curve Z. Compared with the curve X corresponding to the life model without adjusting the repair intensity, it can be seen that the life model of the pre-compensation partial current can make the OLED have less brightness attenuation under the same usage time, thereby reducing the risk of screen burn-in.

[0144] It can be understood that the application of the life model shown in the curve Z can reduce the risk of screen burn-in, but the display brightness of display units with different usage time is still quite different, and the possibility of screen burn-in still exists. Therefore, the adjusted first repair intensity value proposed above can be applied to the life model so that the OLEDs with different usage time all emit light at the first brightness value to repair the screen burn-in phenomenon.

[0145] It can be understood that if the adjusted life model is used to control the display interface of a single display unit, the single display unit will display the first brightness value regardless of how long it is used. Furthermore, after a long period of use, the adjusted life model will formulate the excitation current for the display units with different usage times, and determine the first brightness value based on the linear relationship between the excitation current and the display brightness, so that all display units display the first brightness value. Therefore, after repairing the burn-in screen using the life model corresponding to the straight line Y, the excitation current can be determined based on the current usage time, so that the organic light-emitting diode emits light at the same brightness (i.e., the first brightness value) at different usage times, effectively avoiding the occurrence of burn-in again in a short period of time.

[0146] In some embodiments, the first brightness value may range from 0 to 10,000 nits.

[0147] 606 , determining an excitation current of each display unit according to the first brightness value and the current use time of each display unit.

[0148] It can be understood that by inputting the first repair intensity value into the life model, the brightness that the OLED needs to emit at different usage times (i.e., the first brightness value) can be determined, and the display brightness and excitation current of the organic light emitting diode have a linear relationship. Therefore, the corresponding excitation current can be determined based on the first brightness value and the current usage time of the OELD.

[0149] For example, before the repair intensity is adjusted, each display unit uses the rated current to excite and emit light, and each display unit will reduce the display brightness as the usage time increases. Therefore, different display units have different display brightnesses due to different usage times. After adjusting the repair intensity, the display brightness of all display units needs to be adjusted to the first brightness value. Therefore, based on the first brightness value and the current brightness value corresponding to the rated excitation current at different usage times, the brightness difference that needs to be improved for different display units can be determined, and then the current difference that needs to be compensated for the current current value can be determined, and the corresponding current difference compensation is performed for the display units at different usage times. Different excitation currents are formulated for display units at different usage times, so that the display brightness of each display unit on the interface is the first brightness value, thereby repairing the burn-in phenomenon.

[0150] Exemplarily, the usage time of display unit Q1 is T1 hours, the usage time of display unit Q2 is T2 hours, and T2>T1. Then, under the rated current, the brightness L1 of display unit Q1 is greater than the brightness L2 of display unit Q2, that is, the aging of display unit Q2 is more serious. Therefore, if it is necessary to compensate the brightness of display unit Q1 and the brightness of display unit Q2 to the first brightness value, the adjusted excitation current I1 of display unit Q1 is less than the adjusted excitation current I2 of display unit Q2, so that the display brightness of each display unit on the interface is the first brightness value, and the burn-in phenomenon is repaired.

[0151] It is understood that the OLED in the display screen can be divided into multiple areas to obtain multiple display units. One or more organic light emitting diodes can be included in a single display unit. In some embodiments, A*A organic light emitting diodes can constitute a display unit, such as 2*2, 3*3, 4*4, and each display unit is independently compensated for brightness so that the brightness of the entire display screen tends to the first brightness value.

[0152] 607 , obtaining a user operation on a restore control on the burn-in screen repair interface, and restoring the first repair strength value to an initial repair strength value.

[0153] It can be understood that, when the life model parameters are changed, in order to avoid damage to the display unit of the display screen caused by erroneous parameter modification, a recovery control for restoring the first repair intensity value to the initial repair intensity value can be set on the burn-in repair interface loaded in step 602 above, providing an entry for the user to restore the initial parameter value of the life model. Furthermore, after the first repair intensity value is restored to the initial repair intensity value, the brightness of the display screen can be restored to the brightness before the user adjusted the first adjustment control.

[0154] It is understood that the initial numerical parameters of the life model can be pre-stored in the memory of the electronic device 100 and can be stored in a preset format. For example, the initial parameters of the life model can be written into a display configuration file, or the initial parameters can be written into a display log file.

[0155] 608, obtaining the user's adjustment operation on the brightness control on the burn-in repair interface, and adjusting the backlight brightness of each display unit.

[0156] Exemplarily, the user's brightness modification operation can be obtained through the brightness control, for example, the brightness control is set to a brightness control bar, which can generate a corresponding backlight brightness control signal in response to the user operation of dragging the brightness control bar, and use the backlight brightness control signal to adjust the backlight brightness of the display screen.

[0157] In some embodiments, the backlight brightness control signal may be a pulse width modulation (PWM) signal, and the backlight brightness of the display screen may be controlled by the PWM signal.

[0158] It can be understood that the above-mentioned pulse width modulation is an analog control method for the backlight brightness of the display screen, which modulates the bias of the organic light emitting diode according to the change of the corresponding load, and then controls the conduction time of the organic light emitting diode, thereby achieving the backlight value adjustment of the organic light emitting diode by controlling the conduction time of the organic light emitting diode.

[0159] It is understandable that, since it is difficult for the human eye to perceive the flicker of a single color block with a frequency greater than 60 Hz, the flicker frequency of the organic light-emitting diode is increased. For example, if 1 millisecond is used as a single switching cycle of the organic light-emitting diode, the user's naked eye will find it difficult to perceive the flicker produced by the organic light-emitting diode, but the human eye can observe the reduction in brightness caused by the flicker. For example, the organic light-emitting diode is turned on for 0.5 milliseconds and turned off for 0.5 milliseconds in a switching cycle of 1 millisecond. The user can observe that the display brightness of the organic light-emitting diode at this time is only half of the brightness in the normal light state. Similarly, if the organic light-emitting diode is turned on for 0.1 milliseconds and turned off for 0.9 milliseconds within 1 millisecond, the display brightness of the organic light-emitting diode observed by the human eye is only one-tenth of the brightness in the normal light state. Therefore, the backlight value of the organic light-emitting diode can be adjusted by controlling the switch of the organic light-emitting diode.

[0160] It can be understood that for the human eye, the change in perceived brightness is not linearly uniformly distributed. The grayscale perceived by the human eye is approximately in a power exponential relationship with the actual image input, which can be expressed as f(x) = x^γ, and the value of the grayscale coefficient γ is generally around 2.2. It can be seen that the human eye has a strong ability to distinguish dark images, but a poor ability to distinguish images with higher brightness.

[0161] Among them, the grayscale coefficient (gamma), which can be represented by the Greek letter γ, can be used to characterize the corresponding relationship between the output light curve and the input screen voltage in the display screen, and can be used to calculate the grayscale value of the interface displayed by the display screen.

[0162] Therefore, in some embodiments, based on the fact that the human eye can recognize 256 brightness values ​​corresponding to 256 gray levels, the second brightness value adjusted by the backlight brightness can be set to the brightness threshold corresponding to the gamma grayscale, such as 800-600 nit, 600-90 nit, 90-30 nit, 30-10 nit, 10-2 nit, or 2 nit.

[0163] In some embodiments, reference Fig.12 , wherein the burn-in screen repair interface 1200a includes a burn-in screen area 1204, then in response to the user starting operation, the following three controls can be loaded in the burn-in screen repair interface 1200a:

[0164] (1) A brightness control 1201 that provides access to adjust the backlight brightness;

[0165] (2) an adjustment control 1202 providing an entry for adjusting the intensity of burn-in repair;

[0166] (3) A recovery control 1203 that provides an entry for restoring the initial parameters of the life model.

[0167] Furthermore, the burn-in repair interface 1200a can provide users with entrances to control the burn-in repair intensity, control the backlight brightness and restore the initial parameters of the life model, so that users can change the burn-in repair intensity, backlight brightness and restore the initial parameters of the life model through the above steps 601 to 608, and obtain the interface 1200b after the burn-in screen is repaired.

[0168] It can be understood that the brightness control 1201, the adjustment control 1202 and the recovery control 1203 can all be moved on the burn-in repair interface 1200a to avoid blocking the burn-in area 1204, so as to facilitate the user to observe the burn-in repair effect in real time.

[0169] In some other embodiments, the control providing the entry for adjusting the backlight brightness and the control providing the entry for restoring the initial parameters of the life model may also be associated with a physical button, and the backlight brightness may be adjusted or the initial parameters of the life model may be restored by obtaining the user's touch / click / long press operation on the corresponding physical button. Since the physical button does not occupy the display screen interface, it can avoid affecting the user's observation of the brightness changes in the burn-in area and the non-burn-in area, and avoid affecting the burn-in repair effect.

[0170] It can be understood that according to the specific implementation process of the burn-in screen repair method shown in the above steps 601 to 606 of the example of the embodiment of the present application, the user's startup operation of starting the burn-in screen repair software is obtained, and a burn-in screen repair interface is provided for the user, and the burn-in screen repair interface includes an adjustment control. The user's adjustment operation on the adjustment control is obtained, and the corresponding first repair intensity value is determined based on the adjustment operation. The first repair intensity value is input into the life model to determine the first brightness value, indicating that the brightness of the display screen needs to be adjusted to the first brightness value. Different excitation currents are set for different OLEDs according to the first brightness value and the use time of different OLEDs, so that the brightness of the entire display screen tends to the first brightness value. Thereby, the burn-in screen is effectively repaired, and the user can observe the burn-in screen repair effect in real time with the naked eye, or the user can detect the burn-in screen repair effect in real time through dedicated equipment, which is convenient to use.

[0171] Furthermore, by adjusting the repair intensity value, the most matching life model can be developed for each organic light-emitting diode in the display screen, and the usage time of the organic light-emitting diode can be monitored in real time. By combining the usage time and the parameters of the life model corresponding to the adjusted repair intensity value, the long-term service life of the organic light-emitting diode can be accurately predicted.

[0172] Specifically, the excitation current of the OLED at different usage times can be determined based on the current usage time and the first brightness value, so that the organic light emitting diode emits light at the same first brightness value at different usage times, maintaining the same display brightness, and effectively avoiding screen burn-in again in a short period of time.

[0173] Furthermore, according to the specific implementation process of the burn-in repair method shown in the above steps 607 to 608 of the example of the embodiment of the present application, in response to the user's operation on the recovery control, the parameters of the life model of each display unit can be restored to the initial parameters to avoid device damage to the display unit of the display screen caused by incorrect parameter modification. In response to the user's adjustment operation on the brightness control, the backlight brightness of each display unit can be adjusted, thereby facilitating the user to observe the burn-in repair effect.

[0174] It should be noted that the numbers of the method steps in the present application are only used to identify the steps, and the execution order of the above steps is not limited by the above numbers. The above steps can be executed sequentially, in parallel, or split, and no specific restrictions are made here.

[0182] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

[0183] In some embodiments, the processor 110 may include one or more interfaces. The interface may include a universal serial bus (USB) interface, etc. Among them, the USB interface 130 can be used to connect a charger to charge the electronic device 100, and can also be used to transmit data between the electronic device 100 and a peripheral device.

[0189] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 150, and antenna 2 is coupled to wireless communication module 160, so that electronic device 100 can communicate with the network and other devices through wireless communication technology.

[0190] The electronic device 100 implements the display function through a GPU, a display screen 194, and a display screen control chip 195. The GPU is a microprocessor for image processing, which is connected to the display screen 194 and the display screen control chip 195. The GPU is used to perform mathematical and geometric calculations for graphics rendering. In some embodiments, it can be used to modify the background of the burn-in repair interface according to the user-specified picture, for example, modifying the white picture background to a red picture background. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0191] The display screen control chip 195 can obtain in real time the current usage time and display brightness of a single display unit on the display screen 194. In some embodiments, the display screen control chip 195 can also adjust the parameters of the life model in response to the user's repair operation to obtain a new life model, and control each display unit in the display screen 194 with the new life model to display the interface after the burn-in screen is repaired.

[0192] Exemplarily, the display screen control chip 195 may be a system on chip (SoC) or a timing controller (TCON).

[0193] The timing controller can provide power to the display screen 194 and set a suitable grayscale value for the display signal. In addition, the timing controller can convert the data and control signals transmitted from the front-stage motherboard (such as the processor 110) into the format required by the display screen. For example, the timing controller can convert a low-voltage differential signal (LVDS) into a reduced swing differential signal (RSDS) for use in display screen data driving to realize interface display.

[0194] In some embodiments, a monitoring program is provided in the timing controller, which can be used to monitor the current usage time of the display units in the display screen 194, so as to increase the display brightness of all display units to a first brightness value according to the current usage time and the updated life model, thereby repairing the burn-in phenomenon.

[0195] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED), a flexible light-emitting diode (FLED), Mini-LED, Micro-LED, Micro-OLED, quantum dot light-emitting diodes (QLED), etc. In some embodiments, the electronic device 100 may include 1 or N display screens 194, where N is a positive integer greater than 1.

[0196] In the embodiment of the present application, the display screen 194 can display the burn-in screen repair interface, and can also display the repair intensity control, brightness control, and recovery parameter control loaded on the burn-in screen repair interface.

[0197] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0198] The ISP is used to process the data fed back by the camera 193. For example, when taking a photo or shooting a video, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0199] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, etc. The processor 110 executes various functional applications and data processing of the electronic device 100 by running instructions stored in the internal memory 121 and / or instructions stored in a memory provided in the processor.

[0203] The electronic device 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0204] The pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be disposed on the display screen 194 .

[0205] There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. Capacitive pressure sensors can be at least two parallel plates with conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure based on the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the intensity of the touch operation based on the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch based on the detection signal of the pressure sensor 180A.

[0206] The gyro sensor 180B may be used to determine the motion posture of the electronic device 100 .

[0207] The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally three axes).

[0210] The touch sensor 180K is also called a "touch panel". The touch sensor 180K can be set on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen". The touch sensor 180K is used to detect a touch operation acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194.

[0211] Fig.14 According to some embodiments of the present application, a software structure block diagram of an electronic device 100 is shown.

[0212] It is understood that the software system of the electronic device 100 can adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present invention takes the Android™ system of the layered architecture as an example to exemplify the software structure of the electronic device 100.

[0213] Exemplarily, the layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android™ system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (android runtime) and the system library, and the kernel layer.

[0214] Understandably, Fig.14 The components included in the electronic device 100 shown do not constitute a specific limitation on the electronic device 100. In other embodiments of the present invention, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or separate some components, or arrange the components differently.

[0215] like Fig.14 As shown, the application layer may include a series of application packages, which may include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, screen burn-in repair and other applications.

[0216] The application framework layer provides an application programming interface (API) and a programming framework for applications in the application layer, including various components and services to support developers' Android development.

[0217] The application framework layer includes some predefined functions. The application framework layer may include a view system, a window manager, a resource manager, a content provider, a notification manager, a camera service, a multimedia management module, etc.

[0218] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the display screen, capture the display screen, etc.

[0219] The content provider is used to store and retrieve data and make the data accessible to the application. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc. In some embodiments, the content provider can provide the initial parameters of the life model to the burn-in repair application for restoring the life model parameters of a single display unit on the display screen 194.

[0220] The view system includes visual controls, such as controls for displaying text and controls for displaying images. The view system can be used to build applications. The display interface can be composed of one or more views. For example, the burn-in screen repair interface can include a view for displaying text and a view for displaying images, and then display the layers corresponding to different controls and the layers corresponding to the background image on the burn-in screen repair interface to display the above Figures 2A to 5The burn-in repair interface shown in the figure, as well as the Figures 7 to 12 The burn-in screen repair interface is shown.

[0221] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0222] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0223] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the display in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0224] The camera service is used to call the camera driver (including the front camera and / or the rear camera) in response to the application's request.

[0225] The multimedia management module is used to process the image based on the configuration of the camera service. The specific processing process will be described in detail in the following embodiments.

[0226] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0227] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0228] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0229] The system library may include multiple functional modules, such as surface manager, media libraries, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0230] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0231] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0232] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0233] A 2D graphics engine is a drawing engine for 2D drawings.

[0234] The kernel layer is the layer between the hardware and the above software layer. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver. The hardware may include devices such as camera, display, microphone, processor, and memory.

[0235] In the embodiment of the present application, the display screen in the hardware can display the burn-in screen repair interface. The camera in the hardware can be used to collect images.

[0236] The following is an example of the workflow of the software and hardware of the electronic device 100, in conjunction with a scenario in which a user uses the electronic device 100 to repair a burn-in screen.

[0237] When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into an original input event (including the touch coordinates of the touch operation, the timestamp of the touch operation, and other information). The original input event is stored in the kernel layer. The application framework layer obtains the original input event from the kernel layer and identifies the control corresponding to the input event. When the touch operation is a drag operation, and the control corresponding to the drag operation is, for example, an adjustment control for adjusting the intensity of the burn-in repair in the interface of the burn-in repair application, the burn-in repair application can call the screen display process, for example, call the interface of the application framework layer, and then start the burn-in repair process through the display driver of the kernel layer. The electronic device 100 can call the corresponding burn-in repair process through the interactive operations such as the user's touch / click / long press / drag / space gesture / handle remote control of the adjustment control detected by the display screen, or other operations that can trigger the burn-in repair intensity adjustment process.

[0238] Exemplarily, the burn-in repair application is started, and the view system is called so that the view system provides the user with a burn-in repair interface. When the application is started, the burn-in repair process is constructed in the application framework layer through the interface with the application framework layer. For example, the interface of the application framework layer is called, and the adjustment instruction of the burn-in repair intensity generates a control signal (such as an LVDS image data input signal) for the display screen 194, and the control signal is sent to the display driver of the display control chip 195 in the kernel layer. Then the display driver can call the content provider in the application framework layer to determine the life model corresponding to a single display unit. The display driver adjusts the parameters of the life model built into the content provider according to the life model parameter adjustment instruction to obtain a new life model. At the same time, the display driver builds a monitoring service in the application framework layer to monitor the current usage time of a single display unit in real time. When a new life model is obtained, the display driver will generate a new control signal for the display screen 194 based on the new life model, and then provide a corresponding power supply current for each display unit in the display screen 194 according to the new control signal. For example, to display with the same first brightness value, it is necessary to determine the compensation current for each display unit according to its current usage time combined with the life model, and provide different current compensation for each display unit. This eliminates the display brightness difference of each display unit of the display screen 194 and repairs the screen burn-in phenomenon of the display screen 194.
