[0044] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.

[0045] The organic light-emitting diode (OLED) display brightness compensation method, device, electronic device, and storage medium according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0046] Figure 1 This is an organic light-emitting diode (OLED) display brightness compensation method provided by an embodiment of the present application.

[0047] As Figure 1 shown, the method includes the following steps:

[0048] Step 101: Obtain a plurality of first display screens of the OLED display sent by the vehicle-mounted terminal, the duration of each first display screen, and the first set brightness of the OLED display.

[0049] The execution subject of the embodiment of the present application is an organic light-emitting diode (OLED) display brightness compensation device, which can be set in a server in the cloud.

[0050] Among them, the brightness attenuation of the OLED display is not uniformly attenuated across the entire surface, and there is a problem of uneven brightness attenuation.

[0051] In the embodiment of the present application, obtaining a plurality of first display screens of the OLED display sent by the vehicle-mounted terminal may be obtained by the vehicle-mounted terminal according to a camera or a light sensor set in the vehicle-mounted terminal within the range covering the OLED display, and the duration of the first display screen is counted during the process of collecting each first display screen. Among them, the first set brightness of the OLED display may be the screen brightness collected by the vehicle-mounted terminal through a system-on-a-chip (SOC) when collecting the first display screen, and this screen brightness is usually set in response to user operations. That is to say, each collected first display screen has a corresponding first set brightness; or the first set brightness of the display screen corresponding to each first display screen may be the same.

[0052] Step 102: Divide the display area of the OLED display screen into multiple sub-display areas according to a set size.

[0053] In the embodiment of the present application, since the content displayed in different areas of the display area of the OLED display screen is usually different when displaying a picture, the brightness attenuation conditions of different display areas are different. Therefore, the display area can be divided into multiple sub-display areas according to a set size. For example, the set size is 20 pixel points * 20 pixel points or 30 pixel points * 30 pixel points, and the specific division can be made according to requirements. Among them, the more the number of sub-display areas divided, the more detailed the subsequent brightness compensation for the display screen, and the better the effect of extending the life of the display screen.

[0054] In an implementation manner of the embodiment of the present application, when dividing the display area, the size of each sub-display area can be determined according to the display pictures with longer display frequencies and durations in each OLED display picture collected by the vehicle-mounted terminal, so as to improve the accuracy of dividing each sub-display area and the effect of brightness compensation.

[0055] Step 103: Determine the working duration of each sub-display area at the second set brightness according to each first display picture, the duration of each first display picture, and the first set brightness.

[0056] In the embodiment of the present application, for any first display picture, according to the first display picture displayed in the display area of the OLED display screen, and according to the size of each sub-display area, the second display picture corresponding to each sub-display area is determined. Among them, for different second display pictures, the brightness of the corresponding screen in the sub-display area of the OLED is different. For example, taking the first display picture as the address book, part of the address book is white with a higher brightness, while part of the button area is black with a lower brightness. If the white part is displayed in sub-display area 1, the screen display brightness is higher; if the black part is displayed in sub-display area 2, the screen display brightness is lower. Among them, the second display pictures corresponding to different sub-display areas can be the same or different. And the duration of the second display picture corresponding to each sub-display area is the same as the duration of the first display picture. Therefore, the second display picture corresponding to each sub-display area and the duration of the second display picture displayed in each sub-display area can be determined.

[0057] Furthermore, based on the multiple first display screens shown, the respective second display screens corresponding to each sub-display area and the corresponding duration can be determined. Based on the respective second display screens corresponding to each sub-display area and the corresponding first set brightness, the target brightness of the respective second display screens corresponding to each sub-display area can be determined. Based on the target brightness and duration of the respective second display screens corresponding to each sub-display area, the working duration of each sub-display area at the second set brightness can be calculated, such as the working duration at the highest screen brightness.

[0058] Step 104: Determine the brightness compensation parameters for each sub-display area according to the brightness attenuation curve of the OLED display screen and the working duration of each sub-display area at the second set brightness.

[0059] In the embodiment of the present application, the brightness attenuation curve of the OLED display screen indicates the attenuation situation of the OLED display screen over time under different brightness conditions. As an implementation manner, according to the brightness attenuation curve of the OLED display screen and the working duration of each sub-display area at the second set brightness, the brightness attenuation ratio of each sub-display area is determined, and according to the brightness attenuation ratio of each sub-display area, the brightness compensation parameters of each sub-display area are determined. For example, the brightness of the sub-display area A1 has attenuated to 95% after being used for half a year because it often emits light, while the sub-display area B3 is often in a black background state and is used less, and its brightness still remains at 99.5% of the original after half a year. Since the attenuation ratios of different sub-display areas are already different, it can be seen that the brightness is inconsistent and the phenomenon of ghosting occurs.

[0060] As another implementation manner, according to the brightness attenuation curve of the OLED display screen and the working duration of each sub-display area at the second set brightness, the brightness attenuation value of each sub-display area is determined, and according to the brightness attenuation value of each sub-display area, the brightness compensation parameters of each sub-display area are determined. For example, if the initial brightness value of the display screen is 100 nits, the brightness value of the sub-display area A1 has attenuated by 10 nits after being used for half a year because it often emits light, that is, the brightness value is 90 nits, while the sub-display area B3 is often in a black background state and is used less, and its brightness value has attenuated by 2 nits after half a year, that is, the brightness value is 98 nits. Since the brightness values of different sub-display areas attenuate differently, it can be seen that the brightness is inconsistent and the phenomenon of ghosting occurs.

[0061] Step 105: Send the brightness compensation parameters of each sub-display area to the vehicle-mounted terminal so that the vehicle-mounted terminal performs brightness compensation according to the brightness compensation parameters of each sub-display area.

[0062] In the embodiments of the present application, the determined brightness compensation parameters of each sub-display area are sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal compensates the brightness of each sub-display area according to the brightness compensation parameters of each sub-display area, so that the brightness of each sub-display area is displayed uniformly, avoiding the phenomenon of afterimages. Since the brightness of the OLED display screen is uniform, the display effect is improved, the OLED can continue to be used, and the service life of the display screen is also extended.

[0063] Among them, the brightness compensation parameter can be a compensation electrical parameter, and the compensation electrical parameter can be a compensation current or a compensation voltage.

[0064] In the OLED display screen brightness compensation method of the embodiments of the present application, multiple first display images of the OLED display screen sent by the vehicle-mounted terminal, the duration of each first display image, and the first set brightness of the OLED display screen are obtained. The display area of the OLED display screen is divided into multiple sub-display areas according to a set size. According to each first display image, the duration of each first display image, and the first set brightness, the working duration of each sub-display area at the second set brightness is determined. According to the brightness attenuation curve of the OLED display screen and the working duration of each sub-display area at the second set brightness, the brightness compensation parameters of each sub-display area are determined, and the brightness compensation parameters of each sub-display area are sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal performs brightness compensation according to the brightness compensation parameters of each sub-display area, so that the brightness of each sub-display area is displayed uniformly, avoiding the phenomenon of afterimages. Since the brightness of the OLED display screen is uniform, the display effect is improved, the OLED can continue to be used, and the service life of the display screen is also extended.

[0065] To clearly illustrate the previous embodiment, this embodiment provides another OLED display screen brightness compensation method. Figure 2 As shown in the flowchart of another OLED display screen brightness compensation method provided by the embodiments of the present application, as Figure 2 shown, step 103 above includes the following steps:

[0066] Step 201, determine the second display image corresponding to each sub-display area according to any first display image.

[0067] Among them, for the division situation of the second display image, reference can be made to the explanation in the previous embodiment, and the principle is the same, so it will not be elaborated in this embodiment.

[0068] Step 202, determine the target brightness corresponding to each sub-display area according to the corresponding relationship between the picture information of the second display image corresponding to each sub-display area and the first set brightness.

[0069] Among them, the picture information can be the color of the picture.

[0070] In the embodiments of the present application, there is a corresponding relationship between the color of the display screen and the second brightness. That is to say, when the brightness set on the screen is the second brightness, the brightness corresponding to different colors is different. For example, when the second brightness set on the screen is 10 nits, the target brightness corresponding to the sub-display area showing red is 8 nits, the target brightness corresponding to the sub-display area showing white is 10 nits, and the target brightness corresponding to the sub-display area showing black is 1 nit. This is not listed one by one here.

[0071] In one implementation manner of the embodiments of the present application, the color corresponding to each sub-display area is a single color. For any sub-display area, according to the corresponding relationship between the color of the second display screen corresponding to the sub-display area and the first set brightness, the candidate brightness corresponding to the color is determined. According to the candidate brightness corresponding to the color, the target brightness corresponding to the corresponding sub-display area is determined. That is to say, the candidate brightness is the target brightness of the sub-display area. Thus, when any first display screen is on, the target brightness corresponding to each sub-display area and the duration of the target brightness corresponding to each sub-display area, that is, the duration of the corresponding first display screen, can be determined.

[0072] In another implementation manner of the embodiments of the present application, the picture content displayed in each sub-display area may include multiple colors. For any sub-display area, according to the corresponding relationship between at least one color of the second display screen corresponding to the sub-display area and the first set brightness, the candidate brightness corresponding to at least one color is determined. According to the candidate brightness corresponding to at least one color, the target brightness corresponding to the sub-display area is determined. For example, the target brightness corresponding to the sub-display area is determined by taking the average or weighted average of the multiple candidate brightnesses corresponding to the corresponding sub-display area.

[0073] Step 203: Determine the working duration of each sub-display area at the second set brightness according to the target brightness and duration corresponding to each sub-display area, and the life curve of the OLED display screen.

[0074] In the embodiments of the present application, according to the target brightness and corresponding duration corresponding to each sub-display area, and the life curve of the OLED display screen, the target brightness and corresponding duration corresponding to each sub-display area can be mapped to the working duration of each sub-display area at the second set brightness. Among them, different OLED display screens have different life curves, and the life curve indicates the rate of life attenuation at different brightness levels.

[0075] In the OLED display screen brightness compensation method according to the embodiments of the present application, multiple first display screens of the OLED display screen sent by the vehicle-mounted terminal, the duration of each of the multiple first display screens, and the first set brightness of the OLED display screen are obtained. The display area of the OLED display screen is divided into multiple sub-display areas according to a set size. According to each first display screen, the duration of each first display screen, and the first set brightness, the working duration of each sub-display area at the second set brightness is determined. According to the brightness decay curve of the OLED display screen and the working duration of each sub-display area at the second set brightness, the brightness compensation parameter of each sub-display area is determined. The brightness compensation parameters of each sub-display area are sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal performs brightness compensation according to the brightness compensation parameters of each sub-display area, so that the brightness display of each sub-display area is consistent, avoiding the ghosting phenomenon. Since the brightness of the OLED display screen is consistent, the display effect is improved, the OLED can continue to be used, and the service life of the display screen is also improved.

[0076] To implement the above embodiments, another OLED display screen brightness compensation method is provided in this embodiment, and the execution subject of this method is the vehicle-mounted terminal.

[0077] Figure 3 It is a schematic flowchart of another OLED display screen brightness compensation method provided by the embodiments of the present application. As Figure 3 shown, this method includes the following steps:

[0078] Step 301, obtain multiple first display screens of the OLED display screen and the duration of each first display screen.

[0079] Step 302, obtain the first set brightness of the OLED display screen.

[0080] Step 303, send multiple first display screens of the OLED display screen, the duration of each first display screen, and the first set brightness of the OLED display screen to the cloud.

[0081] Wherein, the cloud is enabled to obtain multiple first display screens of the OLED display screen sent by the vehicle-mounted terminal, the duration of each first display screen, and the first set brightness of the OLED display screen; divide the display area of the OLED display screen into multiple sub-display areas according to a set size; according to each first display screen, the duration of each first display screen, and the first set brightness, determine the working duration of each sub-display area at the second set brightness; according to the brightness decay curve of the OLED display screen and the working duration of each sub-display area at the second set brightness, determine the brightness compensation parameter of each sub-display area.

[0082] Step 304, obtain the brightness compensation parameters of each sub-display area sent by the cloud.

[0083] Step 305: Perform brightness compensation on each sub-display area according to the brightness compensation parameters of each sub-display area.

[0084] Among them, the explanations in the above embodiments are also applicable to the embodiments of the present application. Since the principles are the same, they will not be elaborated in this embodiment.

[0085] In the OLED display screen brightness compensation method according to the embodiments of the present application, the vehicle-mounted terminal sends multiple first display screens of the OLED display screen, the duration of each first display screen, and the first set brightness of the OLED display screen to the cloud, so that the cloud processes them to obtain the brightness compensation parameters of each sub-display area of the display screen, and sends the brightness compensation parameters of each sub-display area to the vehicle-mounted terminal. The vehicle-mounted terminal performs brightness compensation according to the brightness compensation parameters of each sub-display area, so that the brightness display of each sub-display area is consistent, avoiding the afterimage phenomenon. Since the brightness of the OLED display screen is consistent, the display effect is improved, the OLED can continue to be used, and the service life of the display screen is also extended.

[0086] Based on the above embodiments, the embodiments of the present application provide another OLED display screen brightness compensation method, which illustrates how to perform brightness compensation on each sub-display area according to the brightness compensation parameters of each sub-display area. As an implementation, the vehicle-mounted terminal controls the system-on-chip (SOC) to adjust the compensation current corresponding to each sub-display area according to the brightness compensation parameters of each sub-display area, and performs brightness compensation on each sub-display area according to the compensation current corresponding to each sub-display area, achieving the accuracy of compensation current determination and the stability of the compensation current, and improving the brightness compensation effect.

[0087] To implement the above embodiments, an organic light-emitting diode (OLED) display screen brightness compensation device is provided in the embodiments. This device is arranged in the cloud.
