The application of OLED display screens for image display usually directly stimulates the coating on the pixel color unit to emit light by current, so that the mobile terminal has the advantages of good brightness and outstanding color. However, the OLED display screen will burn in after a long time of use. Among them, images with higher contrast and longer use time are more likely to leave afterimages. For example, when a user uses a certain application program (APP) for a long time, and the APP includes an area that keeps the display screen unchanged during the screen switching process, there is a high possibility that an error will occur in the area that keeps the display screen unchanged. Burn-in phenomenon.

In the related art, in order to avoid screen burn-in, all pixels of the entire image of the OLED display screen to be detected are detected and repaired by using a specific OLED screen burn-in detection tool or OLED detection equipment or an OLED screen burn-in repair system, so as to reduce the occurrence of burn-in of the display screen. screen risk. However, this method needs to use corresponding algorithms for calculation and processing of the data collection information of all pixels of the entire image of the display screen, which obviously requires a large space for data storage and calculation. At the same time, this will increase the cost of use, and cannot be applied to mass-produced terminals, resulting in poor user experience and failing to meet the general needs of the majority of users.

Therefore, how to effectively improve the normal display of the OLED display to reduce the occurrence of screen burn-in is an urgent problem to be solved.

Detailed ways

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, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

The burn-in repair method provided by the embodiments of the present disclosure is applied to a scene where a terminal including a display screen performs screen burn-in repair. For example, it is applied to a scenario where a terminal with an OLED display screen is repaired for screen burn-in. Terminals with OLED displays often suffer from image retention (screen burn-in). In related technologies, repairing burn-in screens of OLED displays usually requires the use of specialized detection tools and equipment, or requires the design of complex burn-in repair algorithms ip, and requires large storage and computing space for data collection and repair.

After research, it is found that terminals with OLED displays often have image retention, which is caused by users using a certain APP for a long time, resulting in screen burn-in, and it mainly occurs when the screen has a fixed display area for a long time after the screen display is switched. In the same APP. For example: live broadcast applications, mobile game applications, shopping applications, etc., where there are some fixed display areas on the display screen and the image remains unchanged, afterimages often appear, resulting in screen burn-in.

Therefore, the embodiments of the present disclosure provide a method for repairing screen burn-in, which predetermines burn-in repair parameters for APPs that are likely to cause screen burn-in, and then performs burn-in repair for matching APPs based on the predetermined screen burn-in repair parameters. .

Wherein, different types of APPs produce different screen burn-in phenomena, so in the embodiments of the present disclosure, the screen burn-in phenomena produced by different APPs may be referred to as different screen burn-in repair types. Construct the corresponding relationship between burn-in repair types and burn-in repair parameters. When performing burn-in repair, based on the corresponding relationship between the burn-in repair type and the burn-in repair parameter, the burn-in repair parameter matching the burn-in repair type is determined. And based on the burn-in repair parameters matching the burn-in repair type, the burn-in area to be repaired is repaired, so as to realize the burn-in repair. This burn-in repair method can be performed on the terminal where the burn-in phenomenon occurs, and does not require special detection tools and equipment, nor does it need to design a complicated burn-in repair algorithm, so the implementation is relatively simple and easy to implement.

In one embodiment, when the terminal is triggered to perform screen burn-in repair, a solid-color picture is displayed on the display screen of the terminal to determine the screen burn-in area to be repaired, and perform screen burn-in repair.

Fig. 1 is a flow chart of a method for repairing a burnt screen according to an exemplary embodiment. As shown in Fig. 1 , the method for repairing a burnt screen is used in a terminal and includes the following steps.

In step S11 , in response to the terminal being triggered to perform screen burn-in repair, a solid-color picture is displayed on the display screen.

Fig. 2A is a schematic diagram showing a solid-color picture displayed on a terminal according to an exemplary embodiment. In the embodiment of the present disclosure, the solid-color picture displayed on the display screen may be a grayscale picture or a pure white picture. That is, when the terminal is triggered, a grayscale picture or a pure white picture can be displayed on the display screen of the terminal. By displaying the solid-color screen, it is convenient for the user to quickly confirm whether there is a burn-in area to be repaired on the solid-color screen, and the purpose of quickly locating the burn-in area to be repaired can be achieved. As shown in FIG. 2A , it is a schematic diagram of displaying a solid-color image on a display screen.

In step S12, in response to displaying a burn-in area to be repaired in the solid-color image, a burn-in repair type matching the burn-in area to be repaired is determined.

In the implementation of the present disclosure, if there is a burn-in phenomenon, the burn-in area to be repaired where the burn-in phenomenon exists is highlighted in the solid-color image. Among them, different types of application display screens correspond to different burn-in areas to be repaired.

Fig. 2B is a schematic diagram showing a display screen of a first application on a terminal according to an exemplary embodiment. As shown in FIG. 2B , the solid-color picture may be a solid-color picture of a live application program, and the display area 213 in the solid-color picture is a burn-in area to be repaired.

Fig. 2C is a schematic diagram showing a display screen of a second application on a terminal according to an exemplary embodiment. As shown in FIG. 2C , the solid-color screen is a solid-color screen 211 of a mobile game application, and an area 213 displayed in the solid-color screen is a burn-in area to be repaired.

Fig. 2D is a schematic diagram showing a display screen of a third application on a terminal according to an exemplary embodiment. As shown in FIG. 2D , the solid-color screen may be a solid-color screen of a shopping application, and the area 213 displayed in the solid-color screen is a burn-in area to be repaired.

In the embodiment of the present disclosure, when the screen burn-in area to be repaired is displayed on the solid-color screen, it can be determined that the screen burn-in repair needs to be performed, so the process of executing the burn-in repair can be triggered to continue. In the embodiment of the present disclosure, based on the displayed screen, the screen burn-in repair type corresponding to the currently displayed screen can be matched. For example, in Figure 2B, the burn-in type matching the burn-in area to be repaired is a live broadcast application; in Figure 2C, the burn-in type matching the burn-in area to be repaired is a mobile game application; in Figure 2D, The burn-in type matching the burn-in area to be repaired is a shopping application.

In step S13, based on the corresponding relationship between the burn-in repair type and the burn-in repair parameter, the burn-in repair parameter matching the burn-in repair type is determined.

In the embodiments of the present disclosure, screen burn-in repair parameters for screen burn-in repair are constructed in advance for different application programs (screen burn-in repair types). When different types of applications installed on the terminal have a burn-in phenomenon and perform screen burn-in repair, the burn-in repair parameters that match the burn-in repair type can be determined based on the correspondence between the burn-in repair type and the burn-in repair parameters .

For example: in Figure 2B, when the screen burn phenomenon of the live broadcast application occurs on the terminal, if the screen burn repair type of the live broadcast application is A1, there will be corresponding screen burn repair parameters, and the burn screen repair The parameter is 11; for example: in Fig. 2C, when the screen burning phenomenon occurs in the mobile game application, if the screen burning repair type of the mobile game application is A2, there will be a corresponding screen burning repair parameter, so that the The parameter to be repaired by screen burn-in is 12; for example, in FIG. 2D , when the screen burn-in phenomenon occurs in the shopping application, if the shopping application is A3, there will be a corresponding burn-in repair parameter 13. Therefore, according to the above matching relationship, the corresponding relationship between the burn-in repair type and the burn-in repair parameter, that is, the above-mentioned A1 corresponds to 11; A2 corresponds to 12; A3 corresponds to 13. Through the corresponding relationship such as the above examples, the burn-in repair parameters matching the burn-in repair type are determined.

In step S14, the burn-in area to be repaired is repaired according to the burn-in repair parameters.

In the embodiment of the present disclosure, based on the matched burn-in repair parameters, the burn-in repair parameters can be directly called to quickly repair the burn-in area to be repaired. It is not necessary to use the corresponding algorithm to process the data collection information of all the pixels of the entire image of the terminal display screen, so it can avoid a large amount of data calculation and data storage to a large extent, and can significantly improve the efficiency of screen burn repair. Moreover, the burn-in repair process is also quite simple and convenient, further reducing the cost of burn-in repair, and can be applied to mass-produced terminals to meet the general needs of users.

In the embodiment of the present disclosure, based on different application display screens, the corresponding burn-in repair types are matched respectively. For any specific screen burn-in repair type, the screen burn-in repair types are configured differently in different areas of the application display screen of this type. Burn-in repair parameters, and then quickly based on the corresponding relationship between the burn-in repair type and the burn-in repair parameters, can further improve the burn-in repair efficiency.

In the embodiments of the present disclosure, different burn-in repair strategies (application programs) may correspond to different burn-in repair strategies, and further, matching screen burn-in repair parameters may be determined for different screen burn-in repair types. The burn-in repair parameters include parameters such as brightness compensation parameters, brightness compensation coefficients, and backlight values. For example: A1 in the above corresponds to 11, and its corresponding burn-in repair strategy is B, and B includes parameters such as brightness compensation parameters, brightness compensation coefficients, and backlight values, as well as calculation results of these parameters. A2 in the above corresponds to 12, and its corresponding burn-in repair strategy is C, and C also includes parameters such as brightness compensation parameters, brightness compensation coefficients, and backlight values, as well as calculation results of these parameters. A3 in the above corresponds to 13, and its corresponding burn-in repair strategy is D, and D also includes parameters such as brightness compensation parameters, brightness compensation coefficients, and backlight values, as well as calculation results of these parameters.

In the embodiment of the present disclosure, the construction process of the corresponding relationship between the burn-in repair type and the burn-in repair parameter will be described below.

Fig. 3 is a flow chart of a method for constructing a corresponding relationship between screen burn-in repair types and screen burn-in repair parameters according to an exemplary embodiment, as shown in Fig. 3 , including the following steps:

In step S31, one or more application display screens are determined.

Wherein, in the application display screen used for constructing the corresponding relationship between burn-in repair types and screen burn-in repair parameters in the embodiments of the present disclosure, there are areas where screen burn-in is likely to occur and normal display areas. The application display screen may be an application display screen corresponding to an application program, for example, the application display screen may be one or more application display screens of a live broadcast application display screen, a mobile game application display screen, and a shopping application display screen. It should be understood that the application display screens involved in the embodiments of the present disclosure are not limited to the application display screens related to the above categories, and may also be other types of application display screens.

For the convenience of description, the normal display area is referred to as the first picture display area, and the first picture display area is the display area that keeps the display picture unchanged after the picture is switched and displayed. The second screen display area is the other screen display area in the application display screen except the first screen display area, that is, the area where the burn-in phenomenon occurs in the display screen is called the second screen display area. For example: in Figure 2B, the first screen display area is 211, which is the display area that remains unchanged after screen switching, and the second screen display area is the display other than 211 in the live application display screen Area 213 is an area where screen burn-in is often prone to occur.

In step S32, each application display screen in the one or more application display screens corresponds to a burn-in repair type.

For example: in Figure 2B, it corresponds to a certain display screen in the live broadcast application display screen; in 2C, it corresponds to a certain display screen in the mobile game application display screen; in Figure 2D, it corresponds to a certain display screen in the shopping application display screen Screen; in Figure 2B, let the screen burn repair type corresponding to the live application display screen be A1, in Figure 2B, let the screen burn repair type corresponding to the mobile game application display screen be A2, and in Figure 2D, let the shopping application The burn-in repair type corresponding to the screen is A3, that is, each application display screen of the above-mentioned different burn-in repair types can correspond to a burn-in repair type one by one.

In step S33, according to each type of screen burn-in repair, burn-in repair parameters for performing screen burn-in repair on the first screen display area and the second screen display area are respectively determined.

In the embodiment of the present disclosure, for example: in FIG. 2B , when the screen burn phenomenon of the live broadcast application occurs on the terminal, set the screen burn repair type of the live broadcast application to A1, the display area of the first screen is 211, and the display area of the second screen is 211. The display area is 213, the burn-in repair parameter corresponding to the first screen display area is 201, and the screen burn-in repair parameter corresponding to the second screen display area is 202. For example: in Figure 2C, when the mobile game application program burns the screen on the terminal, set the screen burning repair type of the mobile game application program to A2, the display area of the first screen is 211, and the display area of the second screen is 213 , the first image display area has a corresponding burn-in repair parameter of 301, and the second image display area has a corresponding screen burn-in repair parameter of 302. For example: in Fig. 2D, when the screen burn phenomenon of the shopping application occurs on the terminal, the screen burn repair type of the shopping application is A3, the display area of the first screen is 211, the display area of the second screen is 213, and the display area of the second screen is 213. There is a corresponding burn-in repair parameter of 401 in the display area of a picture, and a corresponding burn-in repair parameter of 402 exists in the second picture display area.

In step S34, a corresponding relationship between burn-in repair types and screen burn-in repair parameters is established.

In the embodiment of the present disclosure, according to the above matching relationship, a corresponding relationship between burn-in repair types and screen burn-in repair parameters can be created. That is, the burn-in repair parameters corresponding to A1 are 201 and 202 respectively; the burn-in repair parameters corresponding to A2 are 301 and 302 respectively; and the burn-in repair parameters corresponding to A3 are 401 and 402 respectively. Through the corresponding relationship such as the above example, the burn-in repair parameters for the first screen display area and the second screen display area in different screen burn-in repair types can be matched for screen burn-in repair.

In the embodiment of the present disclosure, when performing burn-in repair, the burn-in repair may be performed based on the first picture display area and the second picture display area.

In the embodiment of the present disclosure, based on the corresponding relationship between the burn-in repair type and the burn-in repair parameter, the burn-in repair parameter corresponding to the burn-in repair type can be quickly matched. For example, in the above-mentioned embodiment, the burn-in repair types are A1, A2, and A3, and the burn-in repair parameters corresponding to A1 are 201 and 202 respectively, the burn-in repair parameters corresponding to A2 are 301 and 302, and A3 The corresponding burn-in repair parameters are 401 and 402 respectively.
