Description

Background
Currently, Organic Light-Emitting Diode (OLED) display panels are widely used in electronic devices due to their advantages of self-luminescence, low power consumption, and high response rate. Since the OLED is a single-point light emitting device, the attenuation degree of each pixel point is different. When a certain area in the display screen displays the same content for a long time, the pixel points can accelerate aging speed because of continuous luminescence, and residual images are left on the screen, so that the display of the display screen is uneven, namely, a screen burning phenomenon is generated.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The display method provided by the embodiment of the application can be applied to at least the following application scenarios, which are explained below.
Currently, Organic Light-Emitting diodes (OLEDs) are also called Organic electroluminescent displays and Organic Light-Emitting semiconductors. The OLED is a current-type organic light emitting device, and is a phenomenon of emitting light by injection and recombination of carriers. Under the action of an electric field, holes generated by an anode and electrons generated by a cathode move, are respectively injected into a hole transport layer and an electron transport layer, and migrate to a light emitting layer. When the two meet at the light emitting layer, energy excitons are generated, thereby exciting the light emitting molecules to finally generate visible light.
OLEDs have the property of self-luminescence, which limits the lifetime of these organic materials that emit light. When the OLED display screen displays a certain picture for a long time, the organic materials can accelerate aging speed because of continuous light emission, and residual images are left on the OLED display screen. The screen burn-in phenomenon is generated.
As shown in fig. 1, the short video-class application is taken as an example, the short video-class application generally provides an immersive experience of full-screen content, but controls (e.g., like approval, comment, and forward) in an application interface are the same in different videos, that is, content displayed by target display units corresponding to the controls is not updated for a long period of time, and afterimages of the controls are easily left on a display screen. That is, even if the short video application interface is updated to another interface, the target display units corresponding to the controls still retain afterimages of "like", "comment" and "forward", that is, the target display units corresponding to the controls are caused to burn in the screen.
In view of the problems in the related art, embodiments of the present application provide a display method, an apparatus, an electronic device, and a storage medium, which can solve the problem in the related art that when a certain display unit in a display screen displays the same content for a long time, the screen burn-in phenomenon is easily generated.
The method provided by the embodiment of the application can be applied to other scenes with screen burning phenomena of the display screen besides the application scenes.
According to the method provided by the embodiment of the application, the target display unit which is not updated in the display screen within the first preset time length is identified, and then the first display parameter of the target display unit is adjusted to be the second display parameter. Because the second power consumption corresponding to the second display parameter is smaller than the first power consumption corresponding to the first display parameter, the working power consumption of the target display unit which is not updated for a long time can be adjusted by adjusting the display parameter of the target display unit which is not updated for a long time, so that the aging degree of the pixel points which are not updated for a long time can be reduced, and the screen burning phenomenon is further reduced.
Based on the application scenario, the following describes in detail a display method provided in the embodiment of the present application.
Fig. 2 is a flowchart of a display method according to an embodiment of the present disclosure.
As shown in fig. 2, the display method may include steps 210 to 230, and the method is applied to a display device, and specifically as follows:
And step 220, identifying a target display unit of the OLED display screen, the display content of which is not updated within a first preset time, according to the plurality of interface images.
In the display method provided by the embodiment of the application, the target display unit which is not updated in the display screen within the first preset time duration is identified, and then the first display parameter of the target display unit is adjusted to be the second display parameter. Because the second power consumption corresponding to the second display parameter is smaller than the first power consumption corresponding to the first display parameter, the working power consumption of the target display unit which is not updated for a long time can be adjusted by adjusting the display parameter of the target display unit which is not updated for a long time, so that the aging degree of the pixel points which are not updated for a long time can be reduced, and the screen burning phenomenon is further reduced.
The contents of steps 210-230 are described below:
first, step 210 is involved.
A plurality of interface images of the OLED display screen are collected, and the plurality of interface images at least comprise a first image and a second image which are displayed adjacently.
Next, step 220 is involved.
The interface images at least include a first image and a second image which are displayed adjacently, and in step 220, the method may specifically include the following steps:
according to the first image and the second image, identifying a target pixel point of which the display content is not updated within a first preset time from the OLED display screen; and determining a target display unit according to the target pixel point.
According to the first image and the second image which are displayed adjacently, a target display unit can be determined from the OLED display screen, and the target display unit comprises target pixel points of which the display contents are not updated within a first preset time length. Therefore, the pixels which are not updated for a long time can be quickly and accurately identified from the OLED display screen. The display parameters of the target display unit can be adjusted conveniently in the follow-up process.
The above step of identifying a target pixel point whose display content is not updated within a first preset time period from the OLED display screen according to the first image and the second image may specifically include the following steps:
for any pixel point in the OLED display screen, determining a first pixel value of the pixel point in a first image, and determining a second pixel value of the pixel point in a second image; determining a pixel difference of the first pixel value and the second pixel value; determining the pixel point with the pixel difference smaller than a preset threshold value as a third pixel point; and determining the third pixel points which are not updated within the first preset time as target pixel points.
Illustratively, the display content of the OLED display screen is monitored in real time, a plurality of interface images are accumulated, and a third pixel point of a pixel value in each two frames of interface images is calculated by subtracting pixel values of pixel points at the same position in the first image and the second image which are displayed adjacently. And when the third pixel point is not updated within the first preset time, determining the third pixel point as a target pixel point.
Exemplarily, as shown in fig. 3, a subtraction operation of pixel values of the same pixel point is performed on the first image and the second image which are adjacently displayed, the pixel point with the pixel difference of 0 is determined as a third pixel point, the third pixel point which is not updated within a first preset time period is determined as a target pixel point, and then the target display unit is determined according to the target pixel point. As shown in fig. 3, only the bottom plus icon in the first and second images is unchanged for a first preset time period, and the plus icon may be the target display unit.
Therefore, the pixel difference of the first pixel value of the pixel point in the first image and the second pixel value of the pixel point in the second image is determined, the pixel point with the pixel difference smaller than the preset threshold value and not updated within the first preset time is determined as the target pixel point, and the pixel point which is not updated for a long time can be quickly and accurately identified from the OLED display screen.
Finally, step 230 is involved.
In some embodiments of the present application, the step 230 may specifically include the following steps:
and reducing the display brightness of the target display unit from the first brightness value to the second brightness value.
The display brightness is a physical quantity for representing the luminous intensity of the surface of the luminous object, and the unit is candela per square meter or nit. The display brightness is an important index of the luminous intensity of the display screen.
As shown in fig. 4, after the target display unit with the display content not updated within the first preset time period in the OLED display screen is identified, the display brightness of the target display unit is reduced from the first brightness value to the second brightness value. For example, the second luminance value may be 70% of the first luminance value.
In addition, in order to reduce the influence on the user, a slower transition animation can be added in the process of reducing the display brightness of the target display unit from the first brightness value to the second brightness value.
Therefore, the aging degree of pixels which are not updated for a long time in the OLED display screen is favorably slowed down by reducing the display brightness of the target display unit, and the screen burning phenomenon is reduced.
In addition, after the display brightness of the target display unit is adjusted to the second brightness value for a period of time, timing may be started, and if the target display unit has not changed within a preset time (e.g., one minute), the display brightness of the target display unit is adjusted from the second brightness value to the first brightness value, and a new screen monitoring is started. If the screen content changes within a preset time (such as one minute), a new display content monitoring of the display screen is started. Namely, the target display unit of the OLED display screen whose display content is not updated within the first preset time period is restarted to be identified.
Therefore, the organic light emitting diode corresponding to the target display unit can work for preset time at low power consumption, and the aging degree of pixel points of the target display unit in the OLED display screen is reduced.
In other embodiments of the present application, step 230 may specifically include the following steps:
and reducing the component pixel value of at least one single channel of the target pixel point from the first component pixel value to the second component pixel value, wherein the target pixel point is in the target display unit.
After a target display unit with the display content not updated within a first preset time length in the OLED display screen is identified, the color of a pixel point in the target display unit can be changed. As shown in fig. 5, the component pixel value of at least one single channel of the target pixel point in the target display unit may be reduced from the first component pixel value to the second component pixel value.
Illustratively, the component pixel value of the R channel, the component pixel value of the G channel, and the component pixel value of the B channel of the target pixel point are compared, and the highest one of the 3 component pixel values is halved.
In addition, in order to reduce the influence on the user, a slower transition animation can be added in the process of reducing the component pixel value of at least one single channel of the target pixel point from the first component pixel value to the second component pixel value.
Therefore, the component pixel value of at least one single channel of the target pixel point in the target display unit is reduced to the second component pixel value from the first component pixel value, the serious aging condition of the target pixel point which is not updated for a long time can be relieved, and the screen burning phenomenon of the OLED display screen is reduced.
In addition, the component pixel value of at least one single channel of the target pixel point can be reduced from the first component pixel value to the second component pixel value at the same time, and the display brightness of the target display unit is reduced from the first brightness value to the second brightness value, so that the effect similar to the visual impression before adjustment but with lower brightness value is realized.
In some further embodiments of the present application, step 230 may specifically include the following steps:
under the condition that the target display unit meets the preset condition, controlling a first pixel point in the target display unit to be in a first working state and controlling a second pixel point in the target display unit to be in a second working state; the first pixel point is adjacent to the second pixel point; after the second preset time, controlling the first pixel point to be in the second working state, and controlling the second pixel point to be in the first working state;
wherein the preset conditions include: the ratio of the first area of the target display unit to the second area of the OLED display screen is larger than a preset threshold value, and/or the pixel values of the pixel points in the target display unit are the same.
When a large-area pure-color target display unit is monitored in the display screen, pixels in the target display unit are alternately displayed, pixels in the target display unit are periodically and alternately displayed, and on the basis of a first pixel at the upper left corner in the target display unit, the first pixel is in a first working state, and a second pixel adjacent to the first pixel is in a second working state. And so on, the first pixel point adjacent to the second pixel point is in the first working state.
Illustratively, as shown in fig. 6, one first pixel may be lit every other second pixel at the first 30 seconds of each minute; the second pixel can be illuminated 30 seconds after each minute, and the process is repeated in an alternating cycle.
If the ratio of the first area of the target display unit to the second area of the OLED display screen is greater than a preset threshold (for example, one fourth), it indicates that the target display unit occupies a larger display area on the display screen. And if the pixel values of the pixel points in the target display unit are the same, indicating that the target display unit is a pure color display area on the display screen.
When the target display unit meets the preset condition, the target display unit is a pure color display area which is not updated within the first preset time period, or a display area with a larger display area which is not updated within the first preset time period, and such a display area with a larger area and a pure color is not a key area for displaying contents in the interface generally. Therefore, the working state of the target display unit meeting the preset condition is adjusted, the power consumption of the target display unit can be reduced under the condition that the use experience of a user is not obviously influenced, and the service life of the display screen can be prolonged.
In summary, in the embodiment of the present application, the target display unit that is not updated in the display screen within the first preset time period is identified, and then the first display parameter of the target display unit is adjusted to the second display parameter. Because the second power consumption corresponding to the second display parameter is smaller than the first power consumption corresponding to the first display parameter, the working power consumption of the target display unit which is not updated for a long time can be adjusted by adjusting the display parameter of the target display unit which is not updated for a long time, so that the aging degree of the pixel points which are not updated for a long time can be reduced, and the screen burning phenomenon is further reduced.

And the control module is also used for controlling the first pixel point to be in the second working state and controlling the second pixel point to be in the first working state after the second preset time.
Wherein the preset conditions include: the ratio of the first area of the target display unit to the second area of the OLED display screen is larger than a preset threshold value, and/or the pixel values of the pixel points in the target display unit are the same.
