[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The terms "at least one (item)", "at least one of" and the like in the specification and claims of the present application refer to any one, any two or a combination of more than two of the objects included therein. For example, at least one (item) of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" refers to two or more, and its meaning is similar to that of "at least one (item)".

[0023] Nowadays, electronic devices, such as smartphones and tablets, are an indispensable part of our daily lives, and the clarity and accuracy of their displays are directly related to the user experience. However, electronic devices may have display anomalies, which may manifest as image distortion, color distortion, screen flickering, etc. These display anomalies not only affect the normal use of the device, but may also be a signal of more serious problems inside the device.

[0024] Specifically, the display abnormalities of common electronic devices (such as mobile phones, computers, tablets, etc.) can be roughly classified into the following reasons:

[0025] The abnormality of the drawing module of the electronic device causes the screen content generated by the system to be wrong;

[0026] The display path of the electronic device transmits data abnormally, resulting in abnormal display;

[0027] The screen hardware of the electronic device is abnormal, resulting in abnormal display;

[0028] Incorrect settings of software parameters on the electronic device screen lead to abnormal display.

[0029] At present, display anomalies are usually detected on the production line of electronic equipment, that is, display anomalies are detected by manual observation and camera recognition during factory manufacturing. Traditional manual observation and camera recognition methods require a lot of human resources for real-time monitoring and inspection, which increases the cost of inspection. Secondly, manual inspection usually takes a long time to check the display of each device one by one, and is easily affected by human factors, resulting in low inspection efficiency.

[0030] In order to solve the above problems, the embodiment of the present application provides a display abnormality detection method, which determines the expected current value when the first interface image is normally displayed by the proportion of the number of pixels corresponding to the color component in the first interface image, and then, when the first interface image is displayed, the actual current value when the first interface image is displayed is obtained, and finally, the first interface image is judged whether the display is abnormal by the expected current value and the actual current value. This method judges whether the display is abnormal by directly monitoring the change of the screen power supply current, which is more direct and objective. Since the change of the current value is closely related to the screen display state, it can reflect the working state of the screen in real time. The current detection avoids the problem of misjudgment or missed detection due to subjectivity and fatigue in manual detection, thereby improving the accuracy and reliability of detection. The judgment of display abnormality is realized by comparing the current value, which saves the detection cost and improves the efficiency of display abnormality detection compared with the high cost and time-consuming manual detection.

[0031] The display anomaly detection method provided in the embodiment of the present application may be executed by a display anomaly detection device, which may be an electronic device, or a functional module or functional entity in the electronic device. The display anomaly detection method provided in the embodiment of the present application is described below by taking an electronic device executing the display anomaly detection method as an example.

[0032] The display anomaly detection method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] Figure 1 The display abnormality detection method provided in the embodiment of the present application may include the following steps 201 to 204:

[0034] Step 201: The electronic device determines a first proportion of the number of pixels corresponding to a first color component in a first interface image.

[0035] In some embodiments of the present application, the above-mentioned first interface image may include but is not limited to any of the following: a first interface image of an application, a user first interface image of an electronic device, etc.

[0036] In some embodiments of the present application, the first interface image of the above-mentioned application includes but is not limited to: the first interface image of the multimedia application, the first interface image of the game application, the first interface image of the instant messaging application, the first interface image of the map navigation application, etc.

[0037] In some embodiments of the present application, the user first interface image of the electronic device may include but is not limited to: a main first interface image, a negative first screen first interface image, a taskbar first interface image, etc.

[0038] In some embodiments of the present application, the first color component includes at least one of the following: a red (Red, R) component, a green (Green, G) component, and a blue (Blue, B) component.

[0039] It should be noted that the R, G, and B components together form the basis of the RGB color model, where R is used to represent the red intensity of the color, and the value range of the red component is usually an integer between 0 and 255. Among them, 0 means no red at all, and 255 means the red intensity reaches the maximum. G is used to represent the green intensity of the color, and the value range of the green component is also an integer between 0 and 255. 0 means no green at all, and 255 means the green intensity reaches the maximum. B is used to represent the blue intensity of the color, and the value range of the blue component is also an integer between 0 and 255. 0 means no blue at all, and 255 means the blue intensity reaches the maximum.

[0040] In the RGB color model, the first color component may include at least one of the R, G, and B components, while in other color models, such as the YUV color model, the first color component may include at least one of the Y (Luminance / Luma), U (Chrominance / Chroma), and V (Chrominance / Chroma), where represents brightness, that is, grayscale value, which determines the brightness of the image. Y represents the brightness information of the image, and the value range is usually [0, 255], where 0 represents black and 255 represents white. U (Cb) represents chrominance, and together with the Y component determines the color of the pixel. V (Cr) also represents chrominance, and together with the Y and U components provides a complete description of the pixel color.

[0041] In some embodiments of the present application, the number of pixels corresponding to the first color component refers to the number of pixel points in the first interface image whose intensity of the first color component is greater than an intensity threshold.

[0042] In some embodiments of the present application, the intensity threshold may be a value greater than 0. For example, the intensity threshold may be 128, 192, or 255.

[0043] It should be noted that the above-mentioned intensity threshold can be determined according to actual needs, and the embodiments of the present application do not limit this.

[0044] It should be noted that each pixel is usually composed of one or more color components, which together determine the color of the pixel. For the RGB color model, a pixel is composed of three components: red (R), green (G), and blue (B). The value of each component is usually between 0 and 255 (or 0% to 100% brightness), indicating the intensity of the component.

[0045] For example, taking the case where the first color component includes a red component, a green component and a blue component and the intensity threshold is 128, the number of pixels corresponding to the first color component in the first interface image may include: the number of pixels whose red component value is greater than 128, the number of pixels whose green component value is greater than 128, and the number of pixels whose blue component value is greater than 128.

[0046] In some embodiments of the present application, the first proportion may be the proportion of the number of pixels corresponding to the first color component in the first interface image in the total number of pixels in the first interface image.

[0047] It is understandable that the total number of pixels in the first interface image refers to the sum of all pixels in the first interface image. In an image, each pixel carries color information and constitutes the complete content of the image. When calculating the pixel ratio of a certain color component (such as red, green, and blue), the number of pixels of the color component can be compared with the total number of pixels to obtain the ratio of the color component in the entire image. For example, if the resolution of a first interface image is 1024×768, then the total number of pixels in this first interface image is 1024 multiplied by 768, that is, 786432 pixels. The ratio of pixels of the red component is the value obtained by dividing the number of pixels of the red component in the first interface image by the total number of pixels.

[0048] In some embodiments of the present application, after completing drawing the first interface image, the electronic device can traverse the pixel points in the first interface image, obtain the color component corresponding to each pixel point, and count the number of pixels corresponding to the first color component, and then obtain a first proportion of the number of pixels corresponding to the first color component based on the number of pixels corresponding to the first color component and the total number of pixels of the first interface image.

[0049] In some embodiments of the present application, after the electronic device completes drawing the first interface image through SurfaceFlinger, it can count the number of pixels corresponding to the first color component in the first interface image through SurfaceFlinger to obtain a first proportion of the number of pixels corresponding to the first color component.

[0050] It should be noted that SurfaceFlinger is a service in the system of an electronic device, which is mainly responsible for the graphics rendering of the display system interface and application programs, so as to synthesize the graphics display data from different applications and systems into a unified image, and finally send it to the display device for display. Specifically, when SurfaceFlinger obtains all layers, it will start to draw the complete image of the Tth frame. This process includes rendering, synthesis and possible animation effect processing of each layer. After drawing, SurfaceFlinger will send the synthesized image frame to the display device for display.

[0051] The following describes a process of determining a first proportion of the number of pixels corresponding to a first color component in a first interface image by using an example.

[0052] Exemplarily, taking the first color component including R, G, and B components as an example, after the electronic device completes drawing the first interface image of the Tth frame through the Surfaceflinger layer, it traverses each pixel in the first interface image. During the traversal process, the RGB value of each pixel is checked, and three counters can be set respectively to record the number of non-zero (or greater than the intensity threshold) pixels of each color component. Specifically, for the red component, whenever a pixel with a red value greater than 0 is encountered, the value of the red counter is increased by 1. For the green component, whenever a pixel with a green value greater than 0 is encountered, the value of the green counter is increased by 1. Similarly, for the blue component, whenever a pixel with a blue value greater than 0 is encountered, the value of the blue counter is increased by 1. After completing the statistics of each color component, the electronic device can calculate the proportion of each color component to the total number of pixels in the entire image, and obtain the pixel quantity proportions x1, x2, and x3 of the R, G, and B components.

[0053] Step 202: The electronic device determines a first current value according to the first ratio.

[0054] The first current value is the current value of the power supply current required by the screen when the first interface image is normally displayed.

[0055] In some embodiments of the present application, the first current value may be a current value pre-stored in a preset storage space, and there is a corresponding relationship between the first current value and the first proportion.

[0056] In some embodiments of the present application, the electronic device may obtain a first current value corresponding to the first ratio from a preset storage space according to the first ratio.

[0057] It should be noted that the normal display of the first interface image means that the interface image on the screen is presented to the user clearly, stably and accurately, that is, the first interface image is displayed normally.

[0058] In some embodiments of the present application, the above-mentioned screen can be any one of the following: organic light-emitting diode (OLED), light-emitting diode screen (LED), quantum dot light-emitting diode screen (QLED), etc.

[0059] It should be noted that the display anomaly detection method provided in the embodiment of the present application can also be applied to other types of screen display image scenarios, and the embodiment of the present application is not limited to this.

[0060] Step 203: The electronic device determines a second current value while displaying the first interface image.

[0061] The second current value is the current value of the power supply current of the screen when the first interface image is displayed.

[0062] In some embodiments of the present application, the second current value may be the current output by the power module.

[0063] In some embodiments of the present application, the power module may include at least one of the following: VDDI, VDDR, VLIN, and VCI.

[0064] Exemplarily, the second current value is the current value of the current output by VLIN for supplying power to the screen panel when the first interface image is displayed.

[0065] It should be noted that the Voltage-Doubled Driver Interface (VDDI) is mainly used to drive the backlight unit of the LCD display. VDDI usually uses a ring wrapper to convert the input voltage (such as 12V) into the corresponding power supply voltage, and further increases the voltage through the voltage doubling circuit to meet the needs of the backlight drive. Double Data Rate (DDR) memory voltage (Voltage for DDR Memory, VDDR) refers to the module that provides voltage for the DDR memory in the screen controller or integrated GPU. VLIN is a power module that powers the screen panel. Voltage for Core Circuit Interface (VCI) refers to the module that provides voltage for the core circuit interface.

[0066] Through actual measurements, it was found that when the pixels of a screen (such as an OLED screen) emit three different colors, red, green, and blue, respectively, the current consumed is different due to the differences in the light-emitting materials corresponding to each color and their driving voltage requirements.

[0067] This difference is directly reflected in the four independent power supply systems of the screen panel, namely VDDI (usually used to drive digital circuits), VDDR (commonly used to drive high-speed digital circuits such as RAM), VLIN (mainly supplying pixel drive circuits, especially circuits closely related to brightness adjustment), and VCI (providing stable power supply voltage for other integrated circuits). In actual measurements, the current change of the VLIN power supply is greatly affected by the color of the pixel. Since VLIN is directly related to the luminous intensity and color control of the pixel, especially when the screen display changes from dark to bright, or transitions from one color to another, the brightness adjustment demand of the pixel increases significantly, resulting in large fluctuations in the VLIN power supply current.

[0068] In some embodiments of the present application, the electronic device can monitor the current size when each frame of the interface image is refreshed in real time. That is to say, when the screen continuously displays new content, the electronic device can continuously detect and record the real-time value of the current to subsequently determine whether the frame of the interface image displays an abnormality.

[0069] In an embodiment of the present application, the electronic device measures the current value when displaying the first interface image, thereby being able to determine whether the first interface image is displayed normally based on the pixel distribution of each color component in the first interface image and the current value.

[0070] Step 204: The electronic device determines whether the first interface image is displayed abnormally according to the first current value and the second current value.

[0071] In some embodiments of the present application, the electronic device may determine that the first interface image display is abnormal when the difference between the first current value and the second current value is greater than or equal to a current difference threshold; or, the electronic device may determine that the first interface image display is normal when the difference between the first current value and the second current value is less than a circuit difference threshold.

[0072] In some embodiments of the present application, the current difference threshold may be 0.1, 0.3, or 0.5, etc.

[0073] It should be noted that the current difference threshold can be set according to actual needs. For example, a smaller current difference threshold is set when the accuracy requirement is high, or a relatively larger current difference threshold is set when the accuracy requirement is not high. The embodiment of the present application does not limit the specific value of the current difference threshold.

[0074] Exemplarily, in combination with the above example, after drawing the T-th frame interface image, the electronic device counts the proportions of the number of pixels of the R, G, and B color components in the first interface image of the T-th frame as x1, x2, and x3, respectively, and determines that the first current value corresponding to the proportions x1, x2, and x3 is i1. Then, after displaying the T-th frame image, the electronic device detects that the actual current (i.e., the second current value) provided by VLIN to the screen panel is i2. Then, the electronic device calculates the difference between i2 and i1, and when the difference is greater than the current difference threshold (such as 0.3), it determines that the display of the first interface image of the T-th frame is abnormal.

[0075] The display abnormality detection method provided in the embodiment of the present application determines a first proportion of the number of pixels corresponding to the first color component in the first interface image, and determines a first current value based on the first proportion. The first current value is the current value of the power supply current required for the screen to display the first interface image normally. When the first interface image is displayed, a second current value is determined. The second current value is the current value of the power supply current of the screen when the first interface image is displayed. Based on the first current value and the second current value, it is determined whether the first interface image is displayed abnormally. Through this method, the expected current value when the first interface image is normally displayed is determined by the proportion of the number of pixels corresponding to the color component in the first interface image. Then, when the first interface image is displayed, the actual current value when the first interface image is displayed is obtained. Finally, it is determined whether the first interface image is displayed abnormally based on the expected current value and the actual current value. Since this method can realize the judgment of display abnormality by comparing the current value, it can actually save labor costs and improve the efficiency of display abnormality detection.

[0076] In some embodiments of the present application, the above step 204 can be implemented by the following step 204a.

[0077] Step 204a: When the difference between the first current value and the second current value is greater than or equal to the current difference threshold, the electronic device determines that the first interface image display is abnormal.

[0078] In some embodiments of the present application, the electronic device can calculate the difference between the first current value and the second current value, and compare the absolute value of the difference with the current difference threshold. If the absolute value of the difference is greater than or equal to the current difference threshold, it is determined that the first interface image display is abnormal. Conversely, if the absolute value of the difference is less than the current difference threshold, it is determined that the first interface image display is normal.

[0079] Exemplarily, assuming that the first current value is i1 and the second current value is i2, the electronic device calculates the difference between i2 and i1, and when the absolute value of the difference is greater than the current difference threshold (such as 0.3), determines that the first interface image display of the Tth frame is abnormal.

[0080] In an embodiment of the present application, by comparing the difference between the required current value (i.e., theoretical current) when the first interface image is displayed normally and the actual current value after the first interface image is displayed, a current difference threshold is introduced to determine whether the deviation between the actual current and the theoretical current is within an acceptable range. Then, when the deviation between the actual current and the theoretical current is greater than or equal to the current difference threshold, that is, the actual current is larger than the theoretical current, it is determined that the first interface image display is abnormal. In this way, the intelligent judgment mechanism can automatically identify significant current changes caused by display abnormalities, thereby detecting whether the display is abnormal, thereby improving the accuracy of display abnormality detection.

[0081] In some embodiments of the present application, the above step 202 may include the following steps 202a and 202b:

[0082] Step 202a: The electronic device matches the first ratio with at least one set of second ratios in a preset storage space.

[0083] Among them, a group of second proportions corresponds to a current value.

[0084] Step 202b: The electronic device determines the current value corresponding to the second ratio matching the first ratio in the at least one group of second ratios as the first current value.

[0085] The preset storage space includes at least one group of second proportions and a current value corresponding to each group of second proportions.

[0086] In some embodiments of the present application, the above-mentioned preset storage space may be a memory, a hard disk, etc.

[0087] In some embodiments of the present application, each group of second proportions may include a proportion of the number of pixels corresponding to the first color component.

[0088] In some embodiments of the present application, each group of second proportions includes at least one proportion, and one proportion corresponds to one color component in the first color components.

[0089] Exemplarily, taking the example that the first color component includes three color components R, G, and B, and at least one group of second proportions includes three groups of proportions, at least one group of second proportions may include: proportion 1, proportion 2, and proportion 3, wherein proportion 1, proportion 2, and proportion 3 are respectively: [x1, x2, x3], [x4, x5, x6], and [x7, x8, x9], wherein the first proportion (such as x1) in each group of proportions represents the pixel proportion of the R component, the second proportion (such as x2) represents the pixel proportion of the G component, and the third proportion (such as x3) represents the pixel proportion of the B component.

[0090] Furthermore, the current value corresponding to the proportion of 1 may be i3, the current value corresponding to the proportion of 2 may be i4, and the current value corresponding to the proportion of 3 may be i5.

[0091] It should be noted that the above example is only an illustrative description of the second ratio and does not constitute a limitation on the second ratio of the present application.

[0092] In some embodiments of the present application, in at least one group of second proportions, the second proportion matching the first proportion refers to a proportion that is completely identical to the first proportion, or a proportion that differs from the first proportion within a certain accuracy requirement (0.1).

[0093] Exemplarily, taking the example that the first color component includes three color components of R, G, and B, the number of pixels corresponding to the R component in the interface image accounts for 30%, the number of pixels corresponding to the G component accounts for 60, and the number of pixels corresponding to the B component accounts for 35%, that is, the first proportion is [30%, 60%, 35%]. Assuming that the second proportion includes [30%, 60%, 35%], [20%, 40%, 30%], [10%, 60%, 35%], [0, 60%, 60%] and [50%, 60%, 20%] as examples, the second proportion matching the first proportion is [30%, 60%, 35%].

[0094] As another example, taking the example that the first color component includes three color components of R, G, and B, the number of pixels corresponding to the R component in the interface image accounts for 29%, the number of pixels corresponding to the G component accounts for 60%, and the number of pixels corresponding to the B component accounts for 34%, that is, the first proportion is [30%, 60%, 35%]. Assuming that the second proportion includes [30%, 60%, 35%], [20%, 40%, 30%], [10%, 60%, 35%], [0, 60%, 60%] and [50%, 60%, 20%] as examples, the second proportion matching the first proportion is [30%, 60%, 35%].

[0095] In some embodiments of the present application, after determining a second ratio that matches the first ratio, the electronic device can obtain a current value corresponding to the second ratio from a preset storage space and determine the current value as the first current value.

[0096] Exemplarily, in combination with the above example, assuming that the proportion of the R, G, and B color components in the interface image matches the proportion of 1, the current value i3 corresponding to the proportion of 1 is determined as the first current value, that is, the current value of the power supply current required by the screen when displaying the interface image.

[0097] The following describes a process of determining whether the first interface image displays an abnormality based on the first current value and the second current value in conjunction with the accompanying drawings.

[0098] For example, Figure 2 As shown, when the screen of the electronic device is in normal use, the driver layer software will monitor the current size i1 of the screen (panel) in real time. The Surfaceflinger layer software calculates the proportions x1, x2, and x3 of the three colors of red, green, and blue in each frame when drawing, and then passes it to the driver layer through the HWcomposer layer. Then, the driver layer looks up the table to obtain the theoretical current value i2 corresponding to the proportions x1, x2, and x3. Finally, i1 is compared with i2. If the difference is not large, it is judged that the display of this frame is normal. If the difference exceeds 30%, it is judged that the display is abnormal, and the driver layer responds with an error. In this way, a very cost-effective and efficient display abnormality detection can be achieved.

[0099] In some embodiments of the present application, before the above step 202, the display abnormality detection method provided by the embodiment of the present application may further include the following steps 205 to 207:

[0100] Step 205: The electronic device obtains a ratio of the number of pixels corresponding to the first color component in at least one second interface image.

[0101] Among them, the proportion of the number of pixels corresponding to the first color component in the above-mentioned at least one second interface image is different.

[0102] Step 206: The electronic device obtains the current value of the power supply current of the screen when each second interface image is displayed normally.

[0103] Step 207: The electronic device associates and stores the ratio of the number of pixels corresponding to the first color component in at least one second interface image and the current value corresponding to at least one second interface image in a preset storage space.

[0104] In some embodiments of the present application, a set of second proportions is a proportion of the number of pixels corresponding to the first color component in a second interface image.

[0105] Exemplarily, at least one group of second proportions may include: the proportions of the number of pixels corresponding to the three color components R, G, and B in interface image 1, x1, x2, and x3, the proportions of the number of pixels corresponding to the three color components R, G, and B in interface image 2, x4, x5, and x6, and the proportions of the number of pixels corresponding to the three color components R, G, and B in interface image 3, x7, x8, and x9.

[0106] In some embodiments of the present application, the second interface image may be an interface image actually displayed by the electronic device in a normal operating environment or an interface image generated by a simulated environment in a development or test application.

[0107] In some embodiments of the present application, the electronic device can simulate and generate an interface image in an App, and then adjust the pixel ratio of the three color components R, G, and B in the interface image, and detect the current value of the screen after each adjustment of the pixel ratio, and then store the pixel ratio after each adjustment in association with the corresponding current value.

[0108] In some embodiments of the present application, the electronic device may associate and store the ratio of the number of pixels corresponding to the first color component in each second interface image and the current value corresponding to each second interface image in a preset storage space.

[0109] Exemplarily, after starting the test App, the Driver layer software is used to monitor in real time the size of the VLIN current when the interface image of the App is refreshed, and then the proportion of the number of pixels of the three colors of red, green and blue in the interface image is changed to obtain the corresponding current values ​​at different proportions, and the proportions, current values, and the corresponding relationship between the proportions and current values ​​are all recorded and stored in the memory of the electronic device.

[0110] It is understandable that by adjusting the proportion of red, green and blue pixels on the screen (i.e. changing the color distribution of the image), the system can observe the change in the VLIN current value under different color proportions. Through this experiment or debugging process, it is possible to find a direct correlation between the proportion of different color components and current consumption. Furthermore, the corresponding relationship between the current values ​​corresponding to the proportion of different color components is recorded and stored in the memory of the device. These data can be used for subsequent judgment of screen display abnormalities, so that the screen display abnormalities can be detected accurately and quickly in the future.

[0111] In an embodiment of the present application, by recording the corresponding relationship between the proportion of pixels of different colors and the current value of the screen, it is possible to compare and analyze the actual current value of the screen with the recorded theoretical current value when the interface image is displayed to determine whether the current value when the interface image is currently displayed is significantly different from the expected current value, thereby determining whether the current interface image is displayed abnormally, thereby providing strong support for troubleshooting display abnormalities.

[0112] In some embodiments of the present application, after the above step 204, the display abnormality detection method provided in the embodiment of the present application may further include the following step 208:

[0113] Step 208: When the electronic device determines that the first interface image display is abnormal, the electronic device performs a first operation;

[0114] The first operation includes at least one of the following:

[0115] Stop executing screen refresh;

[0116] Output abnormal prompt information, where the abnormal prompt information is used to prompt that the first interface image display is abnormal.

[0117] In some embodiments of the present application, when the electronic device determines that the image display of the first interface is abnormal, it can use software control to suspend sending new image data or frames to the screen, so that the screen remains in the current state or displays a static error page, thereby preventing the erroneous image from continuing to be displayed to the user when the image is abnormal.

[0118] In some embodiments of the present application, when the electronic device determines that the display of the first interface image is abnormal, it can display a clear text message or icon on the screen to indicate the current abnormal display state, or broadcast the abnormal display state through the speaker. Furthermore, it can also provide suggestions for solving the problem or link to support resources on the screen, so as to promptly notify the user or administrator that the first interface image is abnormal and guide them to take corresponding measures (such as restarting the device, contacting technical support, etc.).

[0119] Exemplarily, in combination with the above example, after drawing the T-th frame interface image, the electronic device counts the proportions of the number of pixels of the R, G, and B color components in the first interface image of the T-th frame as x1, x2, and x3, respectively, and after matching the proportions x1, x2, and x3 with the proportion information stored in the memory, determines that the theoretical current value corresponding to the proportions x1, x2, and x3 is i1. Then, after displaying the T-th frame image, the electronic device detects that the actual current value (i.e., the second current value) provided by VLIN to the screen panel is i2. Then, the electronic device calculates the difference between i2 and i1, and when the difference is greater than the current difference threshold (such as 0.3), determines that the display of the first interface image of the T-th frame is abnormal. Finally, in the case of abnormal display, suspends sending new image data or frames to the screen, keeps the screen in the current state or displays a static error page, and displays abnormal status prompt information on the screen.

[0120] In the embodiment of the present application, by timely detecting and responding to the abnormal display of the first interface image, the user experience and reliability of the electronic device are effectively improved. By stopping screen refresh and outputting abnormal prompt information and other measures, further display of the erroneous image is avoided, and the user can be informed of the abnormal display state of the screen in a timely manner, which provides convenience for solving abnormal problems.

[0121] In some embodiments of the present application, the above step 203 can be implemented by the following step 203a.

[0122] Step 203a: When displaying the first interface image, the electronic device obtains a second current value of the current output by the power module through a current measurement circuit.

[0123] In some embodiments of the present application, when the electronic device displays the first interface image, the current measurement circuit can enable the Driver layer software to monitor the magnitude of the VLIN current in real time.

[0124] Exemplarily, the electronic device can measure the voltage across the resistor connected in series with VLIN through the ADC module of the CPU in the current measurement circuit, and calculate the real-time size of the current based on the voltage across the resistor and the resistance value of the resistor, that is, the current value (that is, the second current value) of the current output by the power module in the current measurement circuit.

[0125] In the embodiment of the present application, the ADC module of the CPU is used to measure the current value of the current output by the power module, so that an accurate current value can be obtained. In addition, since the ADC module can convert analog signals into digital signals in real time, the measurement result of the current can be obtained in real time to meet different measurement requirements.

[0126] The display abnormality detection method provided in the embodiment of the present application is exemplarily described below through a specific embodiment.

[0127] like Figure 3 As shown, the display abnormality detection method may include the following steps 101 to 106:

[0128] Step 101: Change the proportion of the number of pixels of the three colors of red, green and blue in the app, and record the corresponding relationship between the proportion x and the current i through the driver.

[0129] For example, the electronic device can change the proportion of the number of pixels of the three colors of red, green and blue in the app, and measure the magnitude of the current i at this time to obtain the corresponding current values ​​at different proportions, and then store all the corresponding relationships in the memory module through the driver layer software.

[0130] Step 102: pass the Tth frame image to Surfaceflinger for drawing through the app.

[0131] For example, when the screen is used normally to refresh the Tth frame, the image information is passed to the surfaceflinger layer software through the app for image data integration processing.

[0132] Step 103: When drawing through Surfaceflinger, calculate the red, green and blue color proportions x1, x2 and x3 and pass them to HWcomposer.

[0133] For example, after obtaining all layers through the Surfaceflinger layer, it will start drawing the complete image of the Tth frame. After drawing, the number of pixels of the three colors of red, green and blue in this frame image is obtained by traversing and counting pixels, and then the proportions of the three colors x1, x2, and x3 are calculated. Finally, the proportion x is passed to the HWcomposer layer along with the frame brushing and image sending.

[0134] It should be noted that the HWcomposer (HWC) layer is a key hardware abstraction layer module in the electronic device system, which is mainly responsible for the synthesis and display of windows (Layer). Specifically, the HWC layer can receive layer data from the upper layer (such as SurfaceFlinger) and perform synthesis processing according to the hardware capabilities.

[0135] Step 104: Pass the proportions x1, x2, and x3 to the Driver layer through HWcomposer to obtain the theoretical current value i2.

[0136] Exemplarily, after receiving the image delivery and data through the HWcomposer layer software, the value of the proportion x is directly passed to the Driver layer along with the frame refresh image delivery.

[0137] Step 105: When the Driver layer waits for the T+1 frame to arrive, it measures the current i1 when the Tth frame image is displayed.

[0138] Exemplarily, after receiving the image and proportion data x of the Tth frame through the Driver layer software, the theoretical screen panel (Panel) current value i2 corresponding to the proportion x in the memory is obtained, and the Tth frame image is refreshed normally.

[0139] Step 106: Determine whether the difference between i1 and i2 exceeds 30%. If so, immediately stop refreshing the frames and report an error. If not, refresh the frames normally.

[0140] For example, when the image of the T+1th frame reaches the Driver layer, the Panel current i1 is read immediately before refreshing the image through the Driver layer, and then i1 is compared with i2. If the difference between the two does not exceed 30%, it is judged that the display is normal, and the frame can be refreshed normally through the Driver layer; if the difference between i1 and i2 exceeds 30%, the Tth frame image is judged as a display abnormality, and the frame refreshing is stopped immediately to preserve the scene, and then reported to the system for a customized error response.

[0141] The above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or, under the premise that there is no contradiction, can also be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of the present application are not limited to this.

[0142] The present application embodiment provides a current measurement circuit, which can be applied to the above-mentioned display abnormality detection method, such as Figure 4 As shown, the current measurement circuit includes a power module 31, a resistor 32, and an analog to digital converter (ADC) module 33, wherein the power module 31 and the resistor 32 are connected in series, a first end of the resistor 32 is connected to a first end of the ADC module 33, and a second end of the resistor is connected to a second end of the ADC module;

[0143] The ADC module 33 is used to measure the voltage across the resistor 32 and obtain the current value of the current output by the power module 31 according to the voltage.

[0144] It should be noted that the above current measurement circuit is a current sensing system based on Ohm's law, which can indirectly measure the current by utilizing the direct relationship between the voltage drop of a resistor and the current.

[0146] In some embodiments of the present application, the power module 31 is used to generate a stable voltage or current to supply the entire circuit. Further, the power module can be a direct current (DC) power supply, and its output voltage can be kept constant.

[0147] In some embodiments of the present application, the third terminal of the ADC module 33 is connected to the first terminal of a central processing unit (CPU).

[0148] In some embodiments of the present application, the voltage across the resistor 32 is measured by an ADC module, and then the current value is inferred using the known resistance value and Ohm's law. Specifically, if the resistance value of the known resistor is R and the measured voltage is V, the current I can be calculated according to Ohm's law I=V / R.

[0149] In the embodiment of the present application, the entire current measurement circuit is connected in series with a resistor of known resistance between the power module and the ADC module, and the voltage drop of the resistor is used to indirectly measure the current output by the power module. The ADC module converts the voltage signal at both ends of the resistor into a digital signal, and then calculates the current value. Thus, the current measurement can be performed simply and accurately.

[0150] The display abnormality detection method provided in the embodiment of the present application can be executed by a display abnormality detection device. In the embodiment of the present application, the display abnormality detection device provided in the embodiment of the present application is described by taking the display abnormality detection device executing the display abnormality detection method as an example.
