The display screen 20 is mounted on the housing 40 to form a display surface of the electronic device 100. In some embodiments, the display screen 20 includes a display area 21 and a non-display area 22. The display area 21 is used for displaying information such as images and texts. The non-display area 22 does not display information. The non-display area 22 may be used to set some functional components, such as a camera, a fingerprint recognition module, and the like. In some embodiments, the non-display area 22 may include a plurality of areas spaced apart from each other. For example, the non-display area 22 may include two areas located at the upper and lower portions of the display area 21.
In some embodiments, the display screen 20 may be displayed full screen. That is, the display 20 includes only the display area 21 and does not include the non-display area, as shown in fig. 2.
In some embodiments, the Display 20 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display.

Functional components such as a camera and a processor may be integrated on the circuit board 30. Meanwhile, the display screen 20 may be electrically connected to the circuit board 30.
In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen 20 to control the display screen 20 to display information.
The housing 40 is used to form the outer contour of the electronic device 100. The housing 40 may be made of plastic or metal. The housing 40 may be integrally formed.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for processing a display frame according to an embodiment of the present disclosure. Specifically, the method comprises the following steps:
in step S101, a picture of the current frame is acquired.
The display screen of the electronic device is formed by fast connecting frames of a plurality of frames, one frame is generally called a frame, and the number of frames per second refers to the number of frames played per second. For example, the standard for movie projection is 24 frames per second.
In the range that human eyes can receive, theoretically, the higher the number of frames per second is, the better the frame number per second is, in practical use, in order to increase the number of frames per second and prevent the image from generating smear, a full black frame is generally inserted into two adjacent frames or several frames to achieve the effect of increasing the total number of frames. The full black frame is a frame of full black picture.
Based on the method, a picture of a current display frame of the display screen is obtained, and the picture may be a normal display picture or a full black picture.
In step S102, it is detected whether or not the adjacent frame of the screen is a full black frame.
When the picture of the normal frame is switched to the full black frame, for example, the picture of the normal frame is switched to the full black frame. A short period of black color is formed which is easily perceived by the human eye. When the picture is switched from the full black frame to the normal frame, the brightness is suddenly changed from black to color, which also causes poor experience for human eyes.
Based on this, it is detected whether the adjacent frame of the current picture is a full black frame, and when it is detected that the adjacent frame of the picture is a full black frame, step S103 is executed; when it is detected that the adjacent frame of the picture is not the full black frame, the process returns to step S101.
In step S103, a brightness gradation parameter is acquired.
When the adjacent frames of the detected picture are all black frames, the perception of human vision can be caused in the switching moment, so that in order to avoid the situation, when the adjacent frames of the detected picture are all black frames, corresponding brightness gradient parameters are obtained, and when the brightness gradient parameters enable the picture to be switched, the brightness change rate is slowed down, the perception degree of human eyes is reduced, and the picture is switched more smoothly.
In some embodiments, the obtaining of the brightness gradient parameter includes two scenarios, one scenario is that when the current frame is a normal frame and the next frame is a full black frame, the current frame needs to be darkened, and then the first brightness gradient parameter needs to be obtained. The other is that when the current frame is a normal frame and the previous frame is a full black frame, the current frame needs to be brightened, and then a second brightness gradient parameter needs to be obtained.
In step S104, the image is processed according to the brightness gradient parameter to achieve the brightness gradient effect during image switching.
And performing brightness gradient processing on the current picture according to the corresponding brightness gradient parameters acquired in the previous step, so that the brightness is gradually changed when the normal picture is switched with the full black frame, and discomfort can not be caused to human eyes.
In one embodiment, the step of processing the picture according to the brightness gradient parameter comprises:
(1) and analyzing the brightness gradient parameter to obtain a gradient effect.
And obtaining the brightness gradient parameter and analyzing to obtain the brightness gradient or the darkness gradient.
(2) Based on the gradual change effect, the duty ratio of the signal pulse for driving the light source is controlled, and the brightness gradual change effect during picture switching is realized.
The duty ratio of the signal pulse for driving the light source can be controlled by a Micro Control Unit (MCU) to realize the processing of gradually brightening or gradually darkening during the picture switching.
As can be seen from the above, in the processing method for a display picture provided in this embodiment, the brightness change gradual change adjustment is performed on the pictures of the adjacent frames of the all-black frame, so that the gray residual image during picture switching is covered, the occurrence of display smear is avoided, and the display efficiency of the pictures is improved.
The method described in the above embodiments is further illustrated in detail by way of example.
Referring to fig. 4, fig. 4 is another schematic flow chart of a method for processing a display screen according to an embodiment of the present disclosure.
Specifically, the method comprises the following steps:
in step S201, a picture of the current frame is acquired.
The method includes the steps of obtaining a picture of a current display frame of a display screen, wherein the picture may be a normal display picture or a full black picture, namely a full black frame.
As shown in fig. 5, fig. 5 is a schematic plan view of a display screen of an electronic device according to an embodiment of the present disclosure. Wherein 1 is a display frame of a normal frame, the display screen 20 is composed of a plurality of pixels 201 to form a normal display frame, and 2 is a full black frame, i.e., a full black frame, where no pixels are formed on the display screen 20. The display screen 3 is a normal frame, and the display screen 20 is composed of a plurality of pixels 201 to form a normal display screen.
In step S202, it is detected whether or not the adjacent frame of the screen is a full black frame.
When the picture of the normal frame is switched to the full black frame, for example, the picture of the normal frame is switched to the full black frame. A short period of black color is formed which is easily perceived by the human eye. When the picture is switched from the full black frame to the normal frame, the brightness is suddenly changed from black to color, which also causes poor experience for human eyes.
Based on this, it is detected whether the adjacent frame of the current picture is a full black frame, and when it is detected that the adjacent frame of the picture is a full black frame, step S203 is executed; when it is detected that the adjacent frame of the picture is not the full black frame, step S206 is performed.
In step S203, a brightness gradation parameter is acquired.
When the adjacent frames of the picture are detected to be full black frames, no matter the picture of the normal frame is switched to be the full black frame or the picture of the full black frame is switched to be the normal frame, the visual perception of human eyes can be caused.
In one embodiment, the step of obtaining the brightness gradient parameter may include:
(1) and when detecting that the next frame of the picture is a full black frame, acquiring a first brightness gradient parameter.
When it is detected that the next frame of the current picture is a full black frame, it indicates that the brightness change of the display screen is a change process from light to dark, and then a first brightness gradient parameter for changing the brightness of the current picture to dark can be correspondingly obtained.
(2) And when the last frame of the picture is detected to be a full black frame, acquiring a second brightness gradient parameter.
When the previous frame of the current picture is detected to be a full black frame, which indicates that the brightness of the display screen changes from dark to bright, a second brightness gradient parameter can be correspondingly obtained, and the second brightness gradient parameter is used for enabling the picture to change gradually brightly.
In step S204, the brightness gradient parameter is analyzed to obtain a gradient effect.
And analyzing the brightness gradient parameters obtained in the previous step to obtain the gradient effect that the gradient effect of the current picture is gradually bright or gradually dark.
In step S205, the duty ratio of the signal pulse that drives the light source is controlled based on the gradation effect.
The micro control unit controls the duty ratio of the signal pulse for driving the light source, and the gradual change control is carried out with the gradual change effect, so that the brightness of the current picture can be slowly darkened from bright or slowly lightened from dark. So that the human eyes can adapt comfortably.
In step S206, it is detected whether the current frame is a full black frame.
When detecting that the adjacent frame of the picture is not a full black frame, detecting whether the current frame is a full black frame, and when detecting that the current frame is a full black frame, executing step S207; when it is detected that the current frame is not a full black frame, the process returns to step S201.
In step S207, the duration value of the full black frame is acquired.
Wherein, during the insertion of the full black frame to be replaced by the picture of the next frame, a short detention occurs, and the detention time may be very short, such as 16.67 ms. Based on this, the time value of the stay is acquired every time the current frame is detected as a full black frame.
In step S208, the sensor assembly on the drive electronics is operated for the duration value.
When the display screen displays a full black frame, the light can penetrate through the display screen more easily because no pixel blocks the display screen. When the sensor assembly of the electronic device is arranged on the inner side of the display screen, i.e. on the side which is not directly visible to the user, the sensor assembly, which may comprise a distance sensor and an ambient light sensor, may be driven into operation for the duration of this full black frame.
As shown in fig. 6, fig. 6 is a schematic structural diagram of a display screen of an electronic device according to an embodiment of the present application. Wherein, a sensor component 22 is disposed on one side of the display screen 20, and when detecting that the current frame is a full black frame, the sensor component emits a detection signal a, and the detection signal a passes through the display screen 20 and generates a reflection signal B after contacting an external object 200 (for example, a user's face). The reflected signal B passes through the display screen 20 back into the sensor assembly 22.
This sensor subassembly can be under the condition of inserting the complete black frame, and transmission and receiving response light that can be better have guaranteed even when using not using the trompil to screen electron device comprehensively, also can let distance sensor and ambient light sensor keep normal work.
Therefore, according to the processing method of the display picture provided by the embodiment, the picture of the adjacent frame of the full black frame is subjected to brightness change gradual change adjustment, so that the gray retention afterimage during picture switching is covered, the display smear is avoided, the display efficiency of the picture is improved, the sensor assembly on the electronic device is driven to work while the black frame is inserted, and the sensing accuracy of the sensor assembly is improved.
In order to better implement the method for processing the display screen provided by the embodiment of the present application, the embodiment of the present application further provides a device based on the method for processing the display screen. The terms are the same as those in the above-described display screen processing method, and details of implementation may refer to the description in the method embodiment.
