In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, a first embodiment of the present application provides a flowchart illustrating a display screen control method. In this embodiment, the display screen control method includes the steps of:
step S10, acquiring the running state of the current running application in the display screen to be detected;
the control method of the display screen in the embodiment is applied to a control system for solving the burn-in of the display screen of the vehicle-mounted OLED (Organic Light-Emitting Diode), referring to fig. 3, where fig. 3 is a schematic diagram of the control system for solving the burn-in of the display screen of the vehicle-mounted OLED, the control system for solving the burn-in of the display screen of the vehicle-mounted OLED in the embodiment is composed of a display screen system and a central control host system, where the display screen burn-in control system is mainly completed by a split display screen end (i.e., multiple display screens cooperate together), the central control host is responsible for providing a display content part, an OLED screen burn-in detection function is added at the split display screen end, and on the premise of saving cost, the problems of matching divergence with other OLED screen suppliers or central control host manufacturers are reduced. The display screen system comprises a touch IC Unit, an OLED screen display Unit, a detection Unit, an MCU (micro controller Unit) Unit and a convection chip, wherein the OLED screen display Unit is mainly responsible for presenting and displaying various functional pictures, feeding back touch key functions and the like; the touch IC (integrated circuit) unit is responsible for receiving touch operation information to form coordinate data and sending the coordinate data to the MCU unit; the MCU unit is responsible for reading touch IC coordinate data, packaging the data according to a protocol, after the data is prepared, and after handshake OK with a host computer, and an FPD-LINK (Flat Panel Display Link, video serial communication) serial bus is normal, the MCU pulls down an INT (interrupt signal) to inform a central control host computer system to read the touch data, so that after the central control host computer system receives the INT signal, the central control host computer system I2C (Inter-Integrated Circuit, two-wire serial bus) reads the touch data through a pair of chips, and the touch function is realized; meanwhile, the MCU is responsible for self-checking the playing application characteristics (such as music, radio, map navigation and the like) of the current display screen system, controlling the detection unit to scan the OLED screen within a preset certain time to detect the voltage drop at two ends of a pixel point, and when detecting that the driving voltage of a certain pixel point continuously exceeds the preset time, feeding back the voltage to the MCU to control pixel displacement switching or brightness adjustment of current pictures, icons, symbols and the like, avoiding screen burning of the screen, and being mainly responsible for reading and fetching data for the chip and providing functional display information and the like for the display screen system. The central control host system is responsible for receiving INT signals sent by the MCU, and reading touch data through the opposite transmission chip to realize a touch function, and the central control host system comprises two opposite transmission chips which are mainly responsible for reading and fetching data and are responsible for providing display information and the like for the display screen system. It can be understood that the OLED screen has a significant defect of burn-in, which is that the OLCD screen displays a static image or picture for a long time, and after the display is turned off, the image is displayed in the screen, and a residual image of the image is left, which is called burn-in. For example, when a user watches a television and plays a television station for a long time (CCTV-1 is taken as an example), after the television is turned off, the residual image of the 'CCTV-1' station logo is still displayed on the position of the television where the 'CCTV-1' is originally displayed, and the residual image is unrecoverable. Similarly, on the automobile electronic product, a user can often play entertainment items such as radio and music during driving, and can not switch after staying on one interface for a long time, so that a large-area screen burning phenomenon exists, and the use and experience of the user are influenced.
Further, in the process that the central control host system and the display screen system normally run the application started by the user, the MCU unit performs self-check on the currently running application, acquires the running state of the currently running application, determines whether the display interface of the currently running application needs to be monitored according to the running state of the currently running application, and determines the monitoring mode of the display interface when the display interface of the currently running application needs to be monitored, so that the waste of system resources is reduced, and the service life of the display screen is prolonged.
Specifically, the step of obtaining the running state of the currently running application in the display screen to be detected includes:
and step S11, performing state self-inspection on the current running application of the display screen to be detected, and acquiring the running state of the current running application.
Specifically, the MCU unit can identify the application characteristics of the display screen to be detected, and the application characteristics can be music, radio, map navigation, etc., that is, the MCU unit can identify the currently running application of the display screen to be detected, and then control the detection unit to perform state self-check on the currently running application in the display screen to be detected based on the connection control relationship with the detection unit, and detect the running state of the currently running application through the detection unit, so as to determine whether to monitor the display interface of the currently running application according to the running state of the currently running application, and determine the monitoring mode of the display interface when the display interface of the currently running application needs to be monitored, so as to reduce the waste of system resources and prolong the service life of the display screen.
Step S20, if the running state is a normal running state, acquiring the layout information of the display interface of the current running application, determining a target layout from the layout information, and acquiring the pressure drop information of a pixel point corresponding to the target layout;
it can be understood that the running state of the currently running application in this embodiment may include a normal running state, a pause running state, a screen-off running state, and the like, where the normal running state refers to a normal running state when the application is in a bright screen, for example, a state of normally playing music or video; the pause running state refers to a running state in which the application is paused when being on a bright screen, for example, a state in which music or video is paused; the screen-off running state refers to a state in which the application is currently in screen-off but still running in the background, such as states of playing music in the background, automatically switching wallpaper in the background, and the like. After the MCU unit obtains the running state of the current running application, if the running state of the current running application is determined to be a normal running state, the detection unit is controlled to obtain the layout information consisting of all the layouts of the display interface in the current running application, part of the layouts in the layout information are filtered according to the software bottom layer architecture and logic information of the current running application, and the target layouts are formed by the remaining layouts after filtering, wherein the layouts refer to part of the whole picture to be displayed in the display interface, for example, a music playing interface can consist of the layouts such as a scroll bar, a music name and a music playing background, the scroll bar, the music name and the music playing background can be respectively used as one layout, the sizes of the layouts can be the same or different, and the target layouts can be formed by one or more layouts; and then further acquiring voltage drop information of pixel points consisting of voltage drops of all pixel points corresponding to the target plate block, so as to detect whether a voltage drop of any pixel point in the voltage drop information of the pixel points of the target plate block meets a preset regulation condition, and when a first target voltage drop meeting the preset regulation condition exists in the voltage drop information of the pixel points of the target plate block, regulating a first target pixel point corresponding to the first target voltage drop, displaying a display interface after the first target pixel point is regulated, avoiding screen burning of the display screen, and prolonging the service life of the display screen, wherein the voltage drop is the change of potential (potential) relative to the same reference point after current flows through a load, which is also called voltage drop.
Further, the step of determining a target tile from the tile information comprises:
step S21, acquiring software bottom layer architecture and logic information of the current running application;
and step S22, according to the software bottom layer architecture and the logic information, performing layout filtering on each layout in the layout information to obtain a target layout.
It can be understood that, when the running state of the currently running application is the normal running state, most of the pictures in the display interface are in real-time change, and a small part of the pictures are fixed and unchangeable for a long time, for example, a station caption in the upper left corner or the upper right corner when watching a television channel. The real-time changing picture can not cause the screen burning phenomenon of the display screen, the picture which is fixed for a long time can cause the screen burning phenomenon of the display screen, the software bottom layer framework and the logic information of the current running application can be used for indicating which picture formed by pixel points is fixed for a long time and which picture formed by the pixel points is changed in real time, and therefore the MCU unit obtains the software bottom layer framework and the logic information of the current running application through the detection unit. Because the plate blocks corresponding to the real-time changing pictures are the plate blocks which do not meet the screen burning condition, and the plate blocks corresponding to the long-time fixed pictures are the plate blocks which meet the screen burning condition, after the software bottom layer architecture and the logic information of the current running application are obtained, the MCU unit filters the plate blocks corresponding to the pictures which form the real-time changing pictures from a plurality of plate blocks of the plate block information according to the software bottom layer architecture and the logic information of the current running application, and forms target plate blocks which need pixel monitoring by the remaining plate blocks corresponding to the pictures which represent the long-time fixed pictures, so as to obtain the pressure drop information of pixel points corresponding to the target plate blocks, and detect whether the pressure drop information of any pixel point in the pixel points corresponding to the target plate blocks meets the preset regulation condition or not, so that when the first target pressure drop which meets the preset regulation condition exists in the pressure drop information of the pixel points corresponding to the target plate blocks, and adjusting the first target pixel point corresponding to the first target voltage drop, and displaying a display interface after the first target pixel point is adjusted, so that the screen burning phenomenon of the display screen is avoided, and the service life of the display screen is prolonged.
Step S30, detecting whether the voltage drop of any pixel point in the voltage drop information of the pixel points of the target block meets the preset regulation condition;
further, after the pressure drop information of the pixel points corresponding to the target block is obtained, the MCU unit detects whether the pressure drop of any pixel point meets a preset adjusting condition or not in the pressure drop information of the pixel points of the target block within a certain time through the detection unit, and the preset adjusting condition is that the duration time for which the pressure drop of the pixel point is kept unchanged is longer than a preset time threshold, so that whether the duration time for which the pressure drop of any pixel point is kept unchanged is longer than the preset time threshold or not in the pressure drop information of the pixel points of the target block is detected. Whether the voltage drop of any pixel point meets the preset adjusting condition or not is detected in the voltage drop information of the pixel points of the target plate block, so that when a first target voltage drop meeting the preset adjusting condition exists in the voltage drop information of the pixel points of the target plate block, a first target pixel point corresponding to the first target voltage drop is adjusted in time, a display interface behind the first target pixel point is adjusted is displayed, the screen burning phenomenon of a display screen is avoided, and the service life of the display screen is prolonged.
Step S40, if a first target voltage drop meeting the preset adjustment condition exists in the voltage drop information of the pixel points of the target block, adjusting a first target pixel point corresponding to the first target voltage drop, and displaying a display interface after the first target pixel point is adjusted.
Furthermore, if the first target voltage drop meeting the preset adjusting condition exists in the voltage drop information of the pixel points of the target plate block detected and determined by the detection unit, the hidden danger of screen burning caused by the existence of the current display interface is indicated, and therefore the detection unit feeds back information to the MCU unit to remind the MCU unit; furthermore, the MCU unit receives feedback information of the detection unit, adjusts the first target pixel point corresponding to the first target voltage drop, and then displays the display interface after the first target pixel point is adjusted. Therefore, the display interface is prevented from having the same picture, icon or symbol to stay for a long time, the screen burning phenomenon of the display screen is avoided, and the service life of the display screen is prolonged.
Further, the step of adjusting the first target pixel point corresponding to the first target voltage drop includes:
step S41, performing pixel displacement on the first target pixel point corresponding to the first target voltage drop.
Further, if it is detected and determined that a first target voltage drop meeting a preset adjusting condition exists in the target voltage drop information, it is indicated that a hidden danger of a screen burning phenomenon exists in the current display interface, and in order to avoid the screen burning phenomenon, the MCU unit may perform pixel displacement on a first target pixel point corresponding to the first target voltage drop. Specifically, the MCU unit can finely adjust the pixel position of the first target pixel point corresponding to the first target voltage drop, for example, the first target pixel point originally located on row 2, row 3, and column 4 is shifted to row 2, and it can be understood that after the first target pixel point is finely adjusted, the position of the first target pixel point can be adjusted back to the position before adjustment, so as to avoid the display interface having the same picture, icon, or symbol staying for a long time, avoid the display screen from being burned, and prolong the service life of the display screen.
Further, the step of adjusting the first target pixel point corresponding to the first target voltage drop includes:
step S41, performing brightness adjustment on the first target pixel point corresponding to the first target voltage drop.
It can be understood that if a first target voltage drop meeting a preset adjusting condition exists in the target voltage drop information through detection and determination, it is described that a hidden danger that a screen burning phenomenon occurs in a current display interface exists, in order to avoid the screen burning phenomenon, the MCU unit may also perform brightness fine adjustment on a first target pixel point corresponding to the first target voltage drop, for example, the brightness of the first target pixel point located on the 2 nd row and the 3 rd column is slightly reduced, and it can be understood that the brightness can be adjusted back to the original brightness after the brightness is reduced, so as to avoid that the display interface has the same picture, icon or symbol to stay for a long time, avoid the screen burning phenomenon occurring in the display screen, and prolong the service life of the display screen.
It can be understood that, since the burn-in phenomenon occurs in the display interface mostly in regions of a certain size, such as a station caption during news broadcasting, and these regions are composed of a certain number of pixel points, in this embodiment, when pixel displacement or brightness adjustment is performed on the first target pixel point, all pixel points meeting preset adjustment conditions within a certain range of the first target pixel point can be adjusted together as a whole, that is, all pixel points meeting preset adjustment conditions in the current block are adjusted as a whole; if the pixel points of the plurality of sections in the display interface all meet the preset adjusting condition, adjusting the pixel points of different sections respectively. Due to the fact that fine position adjustment or fine brightness adjustment is conducted on the pixel points, the situation that the same picture, icon or symbol stays for a long time on a display interface can be avoided under the condition that the impression of a user is not affected, the phenomenon of screen burning of the display screen is avoided, and the service life of the display screen is prolonged.
The embodiment provides a display screen control method, a device and a computer program product, which are used for acquiring the running state of the current running application in a display screen to be detected; if the running state is a normal running state, acquiring the layout information of a display interface of the current running application, determining a target layout from the layout information, and acquiring the pressure drop information of a pixel point corresponding to the target layout; detecting whether the voltage drop of any pixel point meets a preset adjusting condition or not in the voltage drop information of the pixel points of the target block; and if a first target pressure drop meeting the preset adjusting condition exists in the pressure drop information of the pixel points of the target plate block, adjusting a first target pixel point corresponding to the first target pressure drop, and displaying a display interface after the first target pixel point is adjusted. According to the method and the device, the pressure drop information of the pixel points of the target plate in the display interface is monitored according to the running state of the current running application in the display screen to be detected and the plate information of the display interface, and when the target pressure drop meeting the preset adjusting condition exists in the pressure drop information of the pixel points of the target plate, the target pixel points corresponding to the target pressure drop are adjusted in time, the screen burning phenomenon of the display screen is avoided, and the service life of the display screen is prolonged.
Further, referring to fig. 4, a second embodiment of the display screen control method of the present application is proposed based on the first embodiment of the display screen control method of the present application, and in the second embodiment, after the step of obtaining the running state of the currently running application in the display screen to be detected, the method further includes:
step A1, if the running state is a suspended running state, acquiring the layout information of the display interface of the current running application, and acquiring the pressure drop information of the pixel points of each layout in the layout information;
step A2, detecting whether the voltage drop of any pixel point in the voltage drop information of the pixel points of each plate meets the preset adjusting condition;
step A3, if a second target voltage drop meeting the preset adjusting condition exists in the voltage drop information of the pixel points of each plate, adjusting a second target pixel point corresponding to the second target voltage drop, and displaying a display interface after the second target pixel point is adjusted.
Further, after the MCU unit acquires the running state of the current running application, if the running state of the current running application is determined to be the pause running state, because each section in the section information of the display interface in the pause running state is fixed for a long time, each section meets the screen burning condition in the running state, the MCU unit controls the detection unit to acquire the section information consisting of a plurality of sections in the display interface of the current running application, and simultaneously acquires the pressure drop information of pixel points consisting of the pressure drops of the pixel points of all the sections in the section information. Further, the MCU unit controls the detection unit to detect whether the pressure drop of any pixel point in the obtained pressure drop information of the pixel points of each section meets the preset regulation condition, and specifically, the pressure drop of each pixel point in the obtained pressure drop information of the pixel points of each section keeps unchanged duration; and determining whether the pressure drop of any pixel point in the pressure drop information of the pixel points of each section meets the preset regulation condition or not according to the duration time and the preset time threshold value respectively corresponding to the pressure drop of each pixel point. More specifically, when determining whether the pressure drop of any pixel point in the pressure drop information of the pixel points of each block meets the preset regulation condition according to the duration and the preset time threshold value respectively corresponding to the pressure drop of each pixel point: and respectively comparing the duration corresponding to the voltage drop of the current pixel point with a preset time threshold aiming at the voltage drop of each pixel point in the voltage drop information of the pixel points of each section, and if the duration is greater than the preset time threshold, determining that the voltage drop of the current pixel point meets the preset adjusting condition. Further, after determining that a second target voltage drop meeting a preset adjusting condition exists in the voltage drop information of the pixels of each section, the MCU adjusts the second target pixels corresponding to the second target voltage drop, and displays a display interface after the second target pixels are adjusted, so that pixel displacement or brightness adjustment is performed on the second target pixels when the second target pixels corresponding to the second target voltage drop are adjusted.
It can be understood that, after the MCU unit obtains the running state of the current running application, if the running state of the current running application is determined to be the screen-off running state, since the display interface does not output the display information under the screen-off running state, the screen-burning situation of the display screen under this running state is not caused, when the running state of the current running application is determined to be the screen-off running state, the layout information composed of a plurality of layouts in the current running application does not need to be obtained, and the voltage drop of the pixel points of each layout does not need to be monitored, so as to save the running resources of the system, which is beneficial to prolonging the service life of the display screen.
In the embodiment, the MCU monitors the pressure drop information of the pixel points of the target plate in the display interface according to the running state of the current running application in the display screen to be detected and the plate information of the display interface, and timely adjusts the target pixel points corresponding to the target pressure drop when the target pressure drop meeting preset adjusting conditions exists in the pressure drop information of the pixel points of the target plate, so that the screen burning phenomenon of the display screen is avoided, and the service life of the display screen is prolonged.

step S32, determining whether there is a voltage drop of any pixel in the voltage drop information of the pixels of the target block that meets a preset adjustment condition according to the duration and the preset time threshold respectively corresponding to the voltage drop of each pixel.
Further, since the preset adjustment condition is that the duration that the voltage drop of the pixel point is kept unchanged is longer than the preset time threshold, the MCU unit needs to obtain the duration that the voltage drop of each pixel point in the voltage drop information of the pixel point of the target block is kept unchanged through the detection unit, specifically, obtain the duration that the voltage drop of each pixel point in the voltage drop information of the pixel point of the target block is kept unchanged, take the time when the voltage change occurs last time as the start time, calculate the duration according to the time difference between the start time and the current time, until obtaining the duration corresponding to the voltage drop of all the pixel points in the voltage drop information of the pixel point of the target block. Further, the MCU unit compares the duration corresponding to the voltage drop of each pixel point with a preset time threshold value within a certain time through the detection unit, and determines whether the voltage drop of any pixel point in the voltage drop information of the pixel points of the target block meets a preset adjusting condition or not through a comparison result, wherein the preset time threshold value is a time value which can be adjusted according to an actual environment or an actual requirement. When the first target pressure drop meeting the preset adjusting condition exists in the pressure drop information of the pixel points of the target plate block, the first target pixel points corresponding to the first target pressure drop are adjusted in time, the display interface behind the first target pixel points is displayed, the screen burning phenomenon of the display screen is avoided, and the service life of the display screen is prolonged.

Further, when determining whether the voltage drop of any pixel in the voltage drop information of the pixels of the target block meets the preset regulation condition according to the duration time and the preset time threshold respectively corresponding to the voltage drop of each pixel, the MCU unit controls the detection unit to respectively determine whether the voltage drop of each pixel in the voltage drop information of the pixels of the target block meets the preset regulation condition within a certain time, specifically, the voltage drops of all pixels in the voltage drop information of the pixels of the target block can be sorted, the sorting mode can be line-by-line or line-by-line detection, and after the sorting is completed, the voltage drop of the pixel to be currently detected is determined according to the sorted order, and the duration time corresponding to the voltage drop of the current pixel is compared with the preset time threshold to determine whether the duration time of the voltage drop of the current pixel is greater than the preset time threshold, if the duration time of the voltage drop of the current pixel point is greater than a preset time threshold, determining that the voltage drop of the current pixel point meets a preset adjusting condition; on the contrary, if the duration of the voltage drop of the current pixel point is less than or equal to the preset time threshold, it is determined that the voltage drop of the current pixel point does not meet the preset adjustment condition, and no adjustment is needed. And the MCU unit controls the detection unit to execute the step of determining whether the pressure drop of each pixel point in the pressure drop information of the pixel points of the target plate block meets the preset regulation condition for many times until the pressure drop of each pixel point in the pressure drop information of the pixel points of the target plate block is determined.
