[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] Before introducing the specific embodiments of the present disclosure in detail, the application scenario of the present disclosure is first described. The present disclosure can be applied to the detection scenario of aging detection of display screens. At present, organic light-emitting diodes (OLEDs) are self-luminous, and their luminescence process is the process of continuous consumption of OLED materials. Therefore, as time goes by, OLED materials will age, such as their luminance will gradually decrease, color difference will occur, etc. During the use of OLED display screens, the display devices in the display screen will age, resulting in the problem of brightness attenuation of the display screen. According to the different usage conditions of the display devices at different positions, the aging degrees of the display devices at different positions are different, resulting in different brightness attenuation degrees of the display devices at different positions, thereby affecting the display uniformity of the display screen during use, and in severe cases, burn-in may occur. Therefore, it is of great significance to compensate for the aging brightness of the display screen, improve the display effect, and enhance the user experience. In order to ensure the user experience and improve the uniformity of OLED display, before performing aging compensation on the OLED material display panel, it is necessary to perform a life aging test on the display screen in advance to establish an aging attenuation model.

[0054] For example, statistical prediction compensation is usually used to compensate for aging of OLED displays. Specifically, the cumulative usage of the display panel (such as brightness / temperature / time, etc.) is recorded in real time, the attenuation is inferred based on the attenuation model, and the required compensation value (grayscale or voltage, etc.) is determined to complete the compensation. However, statistical prediction compensation requires life aging and testing of the display panel in advance to establish an aging attenuation model. The efficiency and accuracy of the aging attenuation model are key factors in whether the statistical prediction compensation solution can be successfully mass-produced.

[0055] However, in the related art, during the life aging test, it is necessary to use multiple display screens, fixedly light up pure color images with different brightness or grayscale, and repeat the test to establish an aging attenuation model based on the test data. However, using this method will require the use of too much testing equipment, resulting in a large testing workload and low testing efficiency.

[0056] In order to overcome the technical problems existing in the above related technologies, the present disclosure provides a display screen detection method, device, display screen, electronic device and medium. By acquiring the brightness information corresponding to multiple brightness test areas of the display screen; wherein the multiple brightness test areas include a first brightness test area that is periodically displayed according to a first preset display parameter within a preset time period; according to the brightness information corresponding to the multiple brightness test areas, the aging state of the display screen is detected. In this way, in the case of using multiple first brightness test areas that periodically display the first preset display parameter, it is possible to use less test equipment to obtain screen detection data of multiple different test times at one time, which can improve test efficiency and reduce test workload.

[0057] The present disclosure is described below in conjunction with specific embodiments.

[0058] Figure 1 is a flow chart of a display screen detection method according to an exemplary embodiment. Figure 1 As shown, the display screen detection method is used in a terminal, wherein the technical solution of the embodiment of the present disclosure can be specifically applied to mobile phones (such as Android phones, iOS phones, etc.), televisions, tablet computers, mobile Internet devices (Mobile Internet Devices, referred to as "MID"), personal digital assistants (Personal Digital Assistant, referred to as "PDA") and other mobile terminals equipped with OLED display screens. The mobile terminal can also be called user equipment (User Equipment, referred to as "UE"), terminal, wireless terminal or mobile station (Mobile Station, referred to as "MS"), etc., and the present disclosure does not limit it. The method includes the following steps.

[0059] In step S11, brightness information corresponding to a plurality of brightness test areas of the display screen is obtained.

[0060] The plurality of brightness test areas include a first brightness test area that is periodically displayed according to a first preset display parameter within a preset time period.

[0061] In this step, the display screen may include multiple brightness test areas, which are detection areas for detecting the aging status of the display screen. Therefore, first, the brightness information corresponding to the multiple brightness test areas periodically displayed on the display screen according to the first preset display parameters within a preset time period can be obtained.

[0062] For example, the display screen may include multiple brightness test areas, and the multiple brightness test areas may be respectively set at different positions of the display screen, including different area positions such as top, middle, and bottom. Each brightness test area may be set as a first brightness test area that is periodically displayed according to a first preset display parameter within a preset time period, and the first preset display parameter used in each first brightness test area has a different parameter value.

[0063] For example, Figure 2 As shown, at the first moment of the preset time period, the display screen can be Figure 2 The a figure in the figure is displayed, and at the second moment of the preset time period, the Figure 2 The b figure in FIG. 1 is displayed, and at the third moment of the preset time period, the Figure 2 The first moment, the second moment and the third moment can be used as a display cycle, and the preset time period can include several display cycles. Figure 2 Figure a in Figure 2 Figure b in the figure, Figure 2 The area (a1) of the c figure in FIG. 1 indicates that the area with the preset brightness value is in the light state for one third of the time within the preset time period. Figure 2 Figure a in Figure 2 Figure b in the figure, Figure 2 The (a2) area of ​​Figure c in FIG. 1 indicates that the light is on for two-thirds of the preset time period.

[0064] Or, if Figure 3 As shown, at the first moment of the preset time period, the display screen can be Figure 3 The a figure in the figure is displayed, and at the second moment of the preset time period, the Figure 3 The b figure in FIG. 1 is displayed, and at the third moment of the preset time period, the Figure 3 The c figure in FIG. 1 is displayed, and at the fourth moment of the preset time period, the Figure 3 The first moment, the second moment, the third moment and the fourth moment can be used as a display cycle, and the preset time period can include several display cycles. Figure 3 Figure a in Figure 3 Figure b in the figure, Figure 3 Figure c in the figure, Figure 3 The (b1) area of ​​the d figure in FIG. 1 indicates that the area with a brightness value of n1 is lit for a quarter of the time within the preset time period. Figure 3 Figure a in Figure 3 Figure b in the figure, Figure 3 Figure c in the figure, Figure 3The area (b2) of the d figure in FIG. 1 indicates that the area with a brightness value of n1 is lit for two quarters of the time within the preset time period. Figure 3 Figure a in Figure 3 Figure b in the figure, Figure 3 Figure c in the figure, Figure 3 The area (b3) of the diagram d in FIG. 1 indicates that the area with a brightness value of n1 is in a lit state for three quarters of the time within the preset time period.

[0065] In this way, the brightness values ​​of the first brightness test area that uses multiple periodic displays of the first preset display parameters can be obtained at the same time.

[0066] In step S12, the aging state of the display screen is detected according to the brightness information corresponding to the multiple brightness test areas.

[0067] By adopting the above technical solution, the aging state of the display screen is detected by acquiring the brightness information corresponding to multiple brightness test areas of the display screen; wherein the multiple brightness test areas include a first brightness test area that is periodically displayed according to a first preset display parameter within a preset time period; and the brightness information corresponding to the multiple brightness test areas. In this way, when multiple first brightness test areas that periodically display the first preset display parameter are adopted, it is possible to use less test equipment to obtain screen detection data of multiple different test times at one time, which can improve test efficiency and reduce test workload.

[0068] Optionally, the plurality of brightness test areas further include a second brightness test area that is continuously displayed within the preset time period according to a second preset display parameter; therefore, a plurality of brightness information of the first brightness test area and the second brightness test area can be acquired.

[0069] In some embodiments, Figure 4 As shown, Figure 4 Figure a in Figure 4 Figure b in the figure, Figure 4 Figure c in the figure, Figure 4 The (c1, c2, c3) area of ​​the d figure in the figure represents the area with a brightness value of n1, which is lit for one quarter, two quarters, and three quarters of the time in the preset time period, respectively. Figure 4 Figure a in Figure 4 Figure b in the figure, Figure 4 Figure c in the figure, Figure 4 The area (c4) of the d figure in FIG. 1 indicates that the area with a brightness value of n1 is in a lit state within a preset time period.

[0070] In this way, not only the brightness value of the first brightness test area that periodically displays the first preset display parameter can be obtained at the same time, but also the brightness value of the second brightness test area that is continuously displayed within the preset time period can be obtained at the same time.

[0071] In some embodiments, the display parameter includes display brightness and / or display color. The brightness information corresponding to the multiple brightness test areas of the display screen can be obtained in the following manner.

[0072] Method 1: The display parameter is display brightness.

[0073] For example, Figure 5 As shown, Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a11, a21, a31) area of ​​the c figure in the figure represents the area with a brightness value of n1. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a21, a22, a32) area of ​​the c figure in the figure represents the area with a brightness value of n2. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a31, a32, a33) area of ​​the c figure in represents an area with a brightness value of n3, wherein n1, n2, n3 are used to represent different brightness values. In a possible implementation, the brightness value of n1 is greater than the brightness value of n2, and the brightness value of n2 is greater than the brightness value of n3.

[0074] Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a11) of the c figure in the figure represents the area with a brightness value of n1, which is lit for one-third of the preset time period; Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a12) of the c figure in FIG. 1 represents the area with a brightness value of n2, which is lit for one third of the preset time period. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a13) area of ​​the c figure in the figure represents the area with a brightness value of n3, which is lit for one-third of the preset time period. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a21) of the c figure in FIG. 1 represents the area with a brightness value of n1, which is lit for two-thirds of the preset time period; Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a22) of the c figure in FIG. 1 represents the area with a brightness value of n2, which is lit for two-thirds of the preset time period. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a23) of the c figure in the figure represents the area with a brightness value of n3, which is lit for two-thirds of the preset time period; Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The area (a31) of the c figure in FIG. 1 represents the area with a brightness value of n1, which is lit during the preset time period; Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a32) area of ​​the c figure in the figure represents the area with a brightness value of n2, which is lit during the preset time period. Figure 5 Figure a in Figure 5 Figure b in the figure, Figure 5 The (a33) area in Figure c in FIG. 1 represents an area with a brightness value of n3, which is lit within a preset time period.

[0075] Method 2: The display parameter is the display color.

[0076] Among them, you can Figure 5 In the case of changing the different display brightness in the display to different display colors, the display mode of the display screen can be the same as mode one.

[0077] In this way, not only can the brightness value of the first brightness test area that periodically displays the first preset display parameter using multiple display brightnesses and / or display colors and the brightness value of the second brightness test area that continuously displays within the preset time period be obtained at the same time, but also the brightness value of the first brightness test area that periodically displays using multiple display brightnesses and / or display colors and the brightness value of the second brightness test area that continuously displays within the preset time period can be obtained at the same time.

[0078] In some embodiments, when it is determined that the brightness information corresponding to the designated brightness test area is less than or equal to a preset brightness threshold, it is determined that the display screen component at the corresponding position of the designated brightness test area is aged.

[0079] The designated brightness test area includes the first brightness test area or the second brightness test area.

[0080] In some embodiments, the multiple brightness test areas also include a third brightness test area that is always off; therefore, the third brightness test area can be controlled to light up first; and then multiple brightness information of the first brightness test area, the second brightness test area, and the third brightness test area can be obtained.

[0081] For example, the third brightness test area can be kept off during the entire preset time period, but when the screen is detected, the third brightness test area can be controlled to light up, and then multiple brightness information of the third brightness test area can be obtained. Figure 6 As shown, the third brightness test area can be set in the following manner: Figure 6 The (1, 2, 3) area in can be set as the third brightness test area.

[0082] In some embodiments, for each brightness test area, the aging state of the brightness test area at the corresponding position of the display screen is determined according to the brightness information corresponding to the third brightness test area and the brightness information corresponding to the first brightness test area.

[0083] Optionally, the brightness difference can be first determined based on the brightness information corresponding to the third brightness test area and the brightness information corresponding to the first brightness test area; then the aging status of the brightness test area at the corresponding position of the display screen can be determined based on the preset brightness range corresponding to the brightness difference.

[0084] In the above manner, the aging state of the first brightness test area that is periodically displayed can be determined by comparing the brightness information corresponding to the third brightness test area and the brightness information corresponding to the first brightness test area.

[0085] In another possible implementation, the aging state of the brightness test area at the corresponding position of the display screen may be determined according to the brightness information corresponding to the third brightness test area and the brightness information corresponding to the second brightness test area.

[0086] Optionally, the brightness difference can be first determined based on the brightness information corresponding to the third brightness test area and the brightness information corresponding to the second brightness test area; then the aging status of the brightness test area at the corresponding position of the display screen can be determined based on the preset brightness range corresponding to the brightness difference.

[0087] In this way, the aging state of the second brightness test area determined by different display brightness or display color can be compared through the brightness information corresponding to the third brightness test area and the brightness information corresponding to the second brightness test area.

[0088] By adopting the above technical solution, the brightness information corresponding to the third brightness test area can be used to correct the initial brightness difference at different positions to obtain more accurate aging attenuation data.

[0089] In some embodiments, the display screen may also include the first brightness test area, the second brightness test area, and the third brightness test area.

[0094] Optionally, the display parameter includes display brightness and / or display color.

[0095] Optionally, the detection module 702 is configured to determine that aging of the display screen component at a corresponding position of the designated brightness test area occurs when it is determined that the brightness information corresponding to the designated brightness test area is less than or equal to a preset brightness threshold, and the designated brightness test area includes the first brightness test area or the second brightness test area.

[0097] The control submodule 7011 is configured to control the third brightness test area to light up;

[0099] Optionally, the detection module 702 is configured to determine, for each brightness test area, an aging state of the brightness test area at a corresponding position of the display screen according to brightness information corresponding to the third brightness test area and brightness information corresponding to the first brightness test area.
