[0059] In response to the technical problems mentioned in the background technology, the embodiment of the present invention application provides a smart terminal with a screen damage detection function. In a specific embodiment, the smart terminal is a smart phone. In other examples, the smart terminal can also be other smart devices with display screens, such as notebooks, tablet computers, wearable devices (such as smart watches, sports bracelets), smart car-mounted devices, etc.

[0060] The intelligent terminal includes a display screen and a central processing unit. Figure 1As shown, two adjacent sides of the display screen are respectively provided with a plurality of infrared transmitters, and the other two adjacent sides of the display screen are respectively provided with a plurality of infrared receivers, and the central processing unit is connected with the infrared transmitter and the infrared receiver respectively; the central processing unit is used to control the infrared transmitter to send infrared signals to the corresponding infrared receivers, detect the intensity of the infrared signals received by the infrared receivers, and compare the intensity of the received infrared signals with a set threshold value to obtain infrared receivers with abnormal infrared signal intensity.

[0061] The central processing unit is also used to obtain the horizontal coordinate or vertical coordinate corresponding to the abnormal infrared receiver, and calculate the intersection point between each horizontal coordinate and each vertical coordinate, and the coordinate of the intersection point is the coordinate of the screen damage position, wherein each infrared receiver corresponds to a horizontal coordinate or vertical coordinate; Figure 2 As shown, the central processor determines the maximum rectangular screen available area according to the coordinates of the screen damage position, and adaptively adjusts the display size and resolution of the display interface of the smart terminal, and then displays it in the maximum screen available area, so that the user can continue to use the smart terminal even if the display screen is damaged. At the same time, displaying in the maximum screen available area can prevent the user's viewing experience from being affected by the damaged display screen.

[0062] Among them, the display screen is generally composed of a multi-layer structure, mainly including an outer screen and an inner screen. The outer screen refers to a glass cover plate, and the inner screen is used for display and touch. When the screen is detected to be damaged, it may be the outer screen that is damaged, the inner screen that is damaged, or both the inner and outer screens that are damaged. When the outer screen is damaged, only the outer screen glass cover plate needs to be replaced. When the inner screen is damaged, only the entire screen can be replaced. When the inner screen is damaged, both the display and touch may be abnormal. In this application, the infrared transmitter and the infrared receiver can be set on the side of the inner screen, and by detecting whether the inner screen has a damaged position, when the inner screen has a damaged position, the display area of ​​the display screen is adjusted. Alternatively, the infrared transmitter and the infrared receiver can be set between the inner screen and the outer screen, and the damage of the inner screen and the outer screen can be detected respectively. When the inner screen and the outer screen have damaged positions separately or both, the display area of ​​the display screen is adjusted.

[0063] Optionally, the central processing unit is also used to determine two vertical lines of each damaged position coordinate relative to the side of the display screen when two or more damaged position coordinates are obtained, and obtain the coordinates of the intersection of the vertical lines of any two damaged position coordinates, and use each of the vertical line intersection coordinates and each corner of the display screen as diagonal points to divide four rectangular areas, or, when the vertical lines of any two damaged position coordinates intersect, use the two sides of each vertical line and the side of the display screen to divide two rectangular areas; detect whether the rectangular area contains other screen damaged positions, if not, use the rectangular area as the screen available area, compare the area of ​​each screen available area, and obtain the largest screen available area.

[0064] When the CPU obtains two or more damaged position coordinates, the rectangular area is divided as follows: Figure 3-Figure 9 As shown, specifically, Figure 3 Where the coordinates of any two damaged positions are obtained, the two vertical lines of the two damaged position coordinates relative to the side of the display screen are determined, and the coordinates of the intersection of the vertical lines are obtained. The coordinates of each vertical intersection and each corner of the display screen are used as diagonal points to divide four rectangular areas, such as Figure 5 The first, second, third and fourth areas in the figure can avoid the coordinates of the vertical intersection and the two damaged position coordinates. Figure 6 As shown in the figure, when the CPU obtains the intersection of the vertical lines of any two damaged position coordinates, Figure 7-Figure 9 As shown, two rectangular areas are divided from the sides of each vertical line and the side of the display screen. The central processing unit detects whether the rectangular area contains other damaged position coordinates. If not, it is used as the screen available area. The central processing unit generates a screen available area set by using the point set of damaged position coordinates, and compares the area of ​​each screen available area in the set to obtain the largest screen available area.

[0065] The central processing unit is also used to determine the two vertical lines of the damaged location coordinates relative to the side of the display screen when a damaged location coordinate is obtained, divide the two screen available areas with the two sides of each vertical line and the side of the display screen, and compare the area of ​​each screen available area to obtain the largest screen available area.

[0066] Specifically, when the CPU obtains the coordinates of a damaged location, the rectangular area is divided as follows: Figure 10-12 As shown, after determining the two vertical lines of the damaged position coordinates relative to the side of the display screen, two screen available areas are divided by the two sides of each vertical line and the side of the display screen. The central processing unit obtains the largest screen available area by comparing the area of ​​each screen available area in the set.

[0067] Optionally, the central processing unit is also used to generate screen damage results and repair suggestions based on the coordinates of the screen damage location, and display the screen damage results and repair suggestions in a pop-up window reminder via the maximum screen available area.

[0068] Correspondingly, Fig.13 As shown, the present invention also provides a screen damage detection method for a smart terminal, which is applied to the above-mentioned smart terminal. The method is executed by a central processor of the smart terminal and includes the following steps:

[0069] S301: Control the infrared transmitter to send an infrared signal to the corresponding infrared receiver;

[0070] S302: Detecting the intensity of the infrared signal received by the infrared receiver, and comparing the intensity of the received infrared signal with a set threshold value to obtain the infrared receiver having an abnormal intensity of the infrared signal;

[0071] S303: Obtain the horizontal coordinate or vertical coordinate corresponding to the abnormal infrared receiver, and calculate the intersection point between each horizontal coordinate and each vertical coordinate, and obtain the coordinate of the intersection point as the coordinate of the screen damage position, wherein each infrared receiver corresponds to one horizontal coordinate or vertical coordinate;

[0072] S304: Determine a maximum rectangular screen available area according to the coordinates of the screen damage position, and adaptively adjust the display size and resolution of the display interface of the smart terminal before displaying it in the maximum screen available area.

[0073] In a specific example, determining the maximum available rectangular screen area according to the coordinates of the damaged screen position includes the following steps:

[0074] When two or more damage position coordinates are obtained, determining two perpendicular lines of each of the damage position coordinates relative to the side of the display screen;

[0075] Obtain the coordinates of the intersection of any two perpendicular lines of the damaged position coordinates, and use the coordinates of each perpendicular intersection and each corner of the display screen as diagonal points to divide four rectangular areas.

[0076] or,

[0077] When the perpendicular lines of any two damaged position coordinates intersect, two rectangular areas are divided by the two sides of each perpendicular line and the side of the display screen;

[0078] Detecting whether the rectangular area includes other screen damage locations;

[0079] If not, the rectangular area is used as the screen available area, and the areas of each of the screen available areas are compared to obtain the largest screen available area.

[0080] In a specific example, determining the maximum available rectangular screen area according to the coordinates of the damaged screen position includes the following steps:

[0081] When a damaged position coordinate is obtained, two perpendicular lines of the damaged position coordinate relative to the side of the display screen are determined;

[0082] Two available screen areas are divided by the two sides of each vertical line and the side edge of the display screen, and the areas of each available screen area are compared to obtain the largest available screen area.

[0083] The present application provides a method for detecting screen damage of a smart terminal, which further includes the following steps before controlling the infrared transmitter to send an infrared signal to the corresponding infrared receiver:

[0084] Detecting that the smart terminal falls or collides;

[0085] and / or,

[0086] Meet the periodic screen damage detection activation time pre-set by the user;

[0087] and / or,

[0088] A screen damage detection activation command triggered by a user is received.

[0089] The present invention application provides a screen damage detection method for a smart terminal, which can also provide feedback to the user and the manufacturer through the detected damage detection coordinates, and also includes the following steps:

[0090] Generate screen damage results and repair suggestions according to the screen damage position coordinates;

[0091] The screen damage result and the repair suggestion are displayed as a pop-up window through the largest available screen area;

[0092] The screen damage results are sent to the background for big data analysis.

[0093] Among them, the infrared transmitter and the infrared receiver can respectively detect the damage of the inner screen and the outer screen. When the inner screen and the outer screen have damaged positions respectively or both have damaged positions, the screen damage results and repair suggestions are generated according to the coordinates of the screen damage positions. Specifically, when it is detected that both the inner and outer screens are damaged, it is generated that "both the inner and outer screens are damaged, and the entire display screen needs to be replaced"; or, when the outer screen is detected to be damaged, it is generated that "only the outer screen is damaged, just replace the outer screen glass cover" and other suggestions.

[0094] Among them, the screen damage results are sent to the background for big data analysis. Specifically, the statistical data of the screen damage detection structure can be sent to the background for statistical analysis, such as the dangerous scenarios of the terminal when the screen is broken, the falling height and angle, the damage location, or the number of times the danger occurs, the cumulative number of falls, etc., which is convenient for manufacturers to improve and perfect the screen damage protection. The statistical data can also be informed to users to remind users to pay attention to the dangerous situation of screen damage on smart terminals.

[0095] In a specific application scenario, the implementation process of the method is that the smart terminal monitors in real time whether the start-up conditions of infrared damage detection are triggered, which may include detecting dangerous situations such as falling or collision of the smart terminal, or meeting the periodic screen damage detection activation time pre-set by the user, or receiving the screen damage detection activation instruction triggered by the user. When the start-up conditions are met, the infrared transmitter is controlled to send an infrared signal to the corresponding infrared receiver, and the infrared signal strength is compared with the set threshold to determine whether the screen is damaged. When the screen is damaged, the maximum screen available area is determined according to the coordinates of the screen damage position, and the display interface is adaptively adjusted in terms of display size and resolution, and then displayed in the maximum screen available area. Screen damage results and repair suggestions can also be generated according to the coordinates of the screen damage position, and the screen damage results and repair suggestions are fed back to the user through the screen available area, and fed back to the manufacturer by sending it to the background for big data analysis.
