detailed description

The above-described objects, features and advantages of the present disclosure will become more apparent from the aspects of the appended claims.

For the convenience of use, the existing foldable display device can directly enter the normal use state after opening the device regardless of the opening and closing of the display. When the angle between the two screens of the foldable display device is relatively small, if the two screens are simultaneously awake, the problem that the light of the two screens interfere with each other interferes with each other.

An embodiment of the present disclosure provides a screen wake-up method, which is applied to a foldable display device (for example, a mobile phone) to solve the related art when the angle between two screens of the foldable display device is relatively small, and if both screens are simultaneously awake It can cause problems that light interfere with each other. The foldable display device includes a flexible display panel foldable configured as a first sub-display and a second sub-display connected by a connecting member.

Referring to FIG. 1, the method includes the following steps S100 to S600.

S100, determining a relatively static sub-display screen and a relative motion sub-display screen in the first sub-display screen and the second sub-display screen;

In this step, in order to facilitate subsequent determination of the wake-up mode and the wake-up sequence, it is first necessary to determine which of the first sub-display and the second sub-display is a relatively stationary sub-display and which is a relatively moving sub-display.

S200, determining an angle between the first sub-display screen and the second sub-display screen;

S300, determining whether the angle is greater than a first preset angle;

S400, if yes, waking up the relatively stationary sub-display screen;

In the above two steps, when the angle of the device satisfies the first preset angle (for example, 20 degrees), only one side of the screen is awakened. Referring to FIG. 6, when the user opens the device in the folded state, it is usually first viewed. Go to the relatively stationary sub-display (see Figure B, B). Therefore, when the user opens the device in the folded state to the first preset angle, firstly, only the relatively static sub-display B is woken up, and the A screen temporarily does not wake up to maintain the information screen, thereby preventing the bright screen from being bright at the same time, causing reflection. After step S400, the method further includes steps S500 and S600.

Adjusting the brightness of the relatively stationary sub-display according to the corresponding relationship between the angle and the brightness, wherein the correspondence is that the brightness increases as the angle increases. In the case of a small angle, the user does not see too much content of the relatively stationary sub-display, and the low brightness of the sub-display can give the eye a gradual adaptation process.

In some alternative embodiments, S400 may be followed by S401 to adjust the brightness of the relatively stationary sub-display in accordance with a first specific rule (see Figure 2). The first specific rule is: gradually increasing the brightness of the relatively static sub-display according to the first preset rate according to the increasing angle between the first sub-display screen and the second sub-display screen .

Specifically, in order to prevent the brightness of the display screen just waking up from affecting the user experience, in actual application, the brightness of the display screen just after being awake is weak, and according to the relationship between the first sub display and the second sub display The continual increase of the angle gradually increases the brightness of the display at a certain rate to slowly adapt to the user's senses. The rate can be preset according to actual needs, and should be able to adjust according to the speed at which the user turns on the device.

S500: Determine whether the angle is greater than a second preset angle, and the second preset angle is greater than the first preset angle.

S600, if yes, waking up the relative motion sub-display.

In the above two steps, when the angle between the two sub-screens exceeds the second preset angle (for example, 90 degrees), wake up A on the basis of B bright screen: at this time, the light interference between the screens on both sides has been Not strong, and users can see both screens at the same time.

In some optional embodiments, after S600, the method further includes:

Adjusting the brightness of the relatively moving sub-display according to the corresponding relationship between the angle and the brightness, wherein the corresponding relationship is that the brightness increases as the angle increases.

Specifically, S600 may be followed by S601 to adjust the brightness of the relatively moving sub-display according to the second specific rule (refer to FIG. 2). The second specific rule is: gradually increasing the brightness of the relative motion sub-display according to the second preset rate according to the increasing angle between the first sub-display screen and the second sub-display screen .

For the specific implementation of this step, refer to S401, and details are not described herein again. It is worth noting that in this step, the relatively moving sub-display wakes up later than the relatively stationary sub-display, at which point the brightness of the former has reached a certain intensity. Therefore, considering that the user has adapted to the strong brightness, the initial brightness and the increasing rate of the brightness corresponding to the second specific rule may be appropriately improved compared with the first specific rule, and the actual application may be designed according to the specific situation. .

Optionally, the brightness of the relatively stationary sub-display is higher than the brightness of the relatively moving sub-display relative to the same angle. In general, the user's line of sight is concentrated on a relatively stationary sub-display, the relative motion of the sub-display is less bright than the relatively stationary sub-display, and the relatively moving sub-display is not too bright, projected to relative The static sub-display has low light and does not cause too much interference to the relatively stationary sub-display, and the degree of reflection is small.

Referring to FIG. 2, S100 can include the following steps:

S101. Obtain an angle change rate of the first sub display screen and the second sub display screen by using the sensor respectively.

S102. Determine that the sub-display screen with the large angle change rate is a relative motion sub-display screen, and the sub-display screen with a small angle change rate is a relatively static sub-display screen.

The above two steps can be implemented, for example, by a sensor embedded on a sub-display or on two sub-displays (for example, a three-axis gyroscope). The angle change rate of the two sub-display screens is obtained by the three-axis gyroscope, and the sub-display screen with the large angle change rate is determined as the relative motion sub-display screen by comparing the angle change rate, and the angle change rate is small. The sub display is a relatively stationary sub display.

Correspondingly, the S200 can also be implemented by using the sensor (for example, a three-axis gyroscope), and directly obtain an angle between the display screens according to the angle information obtained by the sensor.

The specific implementation manner of the screen wake-up method provided by the embodiment of the present disclosure is as follows:

First, a three-axis gyroscope is embedded on the sub-display screen of the foldable display device, and the angle information of the two sub-display screens is obtained by the gyroscope. By comparing the angle change rates of the two sub-display screens, it can be known which screen is relatively stationary (angle change) The rate is relatively small), which screen is relatively moving (the rate of change of angle is relatively large). In everyday applications, when a folded device is placed on a countertop, the user will fix one sub-display and the other sub-display will open the device in relative motion.

Next, during the opening process of the folding device, the relatively static sub-display will be preferentially seen by the user, so that the relatively stationary sub-display can be awakened as the main screen, and the relatively moving sub-display does not wake up temporarily. The relative motion of the sub-display screen is maintained to prevent the two sub-displays from being lit at the same time, causing reflection.

Further, when the angle between the relatively moving sub-display screen and the relatively stationary sub-display screen satisfies the first preset angle, for example, 20 degrees, the relatively moving sub-display screen is awakened, and the bright screen is displayed. In order to reduce power consumption and improve the user's visual experience, the brightness of the screen is brighter and brighter after the two sub-displays are brighter, and the brightness is improved by following the change of the angle.

As the angle between the sub-displays increases, when the angle exceeds the second preset angle, for example, 90 degrees, the light interference between the two sub-displays is not obvious, and the user can simultaneously Seeing the two screens, so the relatively static sub-display is based on the bright screen, waking up the relative movement of the sub-display.

Compared with the related art, the embodiment of the present disclosure can at least achieve the following effects:

Providing a method for calculating a current opening angle of a device, using a sensor (three-axis gyroscope) to judge that when the device is opened to a small angle, only one side of the screen is awakened and the brightness of the screen is dynamically adjusted according to the angle; when the device is turned on At the angle, the other screen is awakened; thus avoiding the problem of reflective interference caused by the light illuminating the two screens at a small angle.

Some embodiments of the present disclosure provide a screen wake-up method, as described with reference to FIG. 3, the method includes the following steps S100 to S104, S200 to S204, and S300 to S600.

S100. Determine a relatively static sub-display screen and a relative motion sub-display screen (not shown) in the first sub-display screen and the second sub-display screen.

This determination step includes the following substeps:

S103. Obtain image information by using a camera on the first sub-display;

S104. Determine a relatively static sub-display screen and a relative motion sub-display screen according to the facial information in the image information.

The above two steps can be implemented, for example, by a camera provided on the device. In practice, the camera is usually set on a sub-display. At this time, regardless of whether the sub-display provided with the camera is a relatively stationary sub-display or a relatively moving sub-display, at least the image information can be obtained by the camera, and then the face information in the image information (for example, the direction of the user's head) And motion conditions) determine and determine the relatively stationary sub-display and the relative motion of the sub-display. For example, referring to FIG. 6, when the user opens the folding device to a certain angle, it looks to the B portion of the device; at this time, if the camera is located at A, the obtained image of the user's head is positive, and at this time, if the user As the head image changes (for example, becomes larger), it can be determined that B is a relatively static sub-display and A is a relatively moving camera.

S200, determining an angle between the first sub-display screen and the second sub-display screen (not shown);

After determining the relative motion and the relatively stationary sub-display, this step is used to determine the angle between the two sub-displays. Specifically, the following sub-steps S201 to S204 may be included.

S201. Acquire image information obtained by the camera on the first sub-display to capture the second sub-display.

For example, referring to Figure 6, when the user opens the folding device to a certain angle, looking at the device B (relatively stationary sub-display), the camera is located at A (relatively moving sub-display), and the camera can obtain B Image information (relative to the stationary sub-display).

S202. Calculate, according to the image information, a size that is imaged by the second sub-display in the camera.

Specifically, according to the image information of the B (relative still sub-display), the outline of the mobile phone is extracted from the image data of the camera, and the size of the image of B (relative still sub-display) is calculated.

S203. Obtain a distance between the first sub-display screen and the second sub-display screen by using an imaging formula.

The imaging formula in this step is:

Where P is the size (length) of B (relatively stationary sub-display) imaged in the camera, Q is the actual size of the foldable display device, R is the size of the camera aperture R, D is the distance, and L is the object distance. In the case where P, Q, D, and R are known, L can be reversed by the imaging formula to obtain the distance between A and B.

S204. Obtain an angle between the first sub-display screen and the second sub-display screen by using a trigonometric function.

According to the distance between A and B obtained in S203, a trigonometric function can be used to obtain an angle between the two sub-display screens.

S300, determining whether the angle is greater than a first preset angle;

S400, if yes, waking up the relatively stationary sub-display screen;

S500: Determine whether the angle is greater than a second preset angle;

S600, if yes, waking up the relative motion sub-display.

The content of the foregoing embodiment may be referred to in S300 and S600, and details are not described herein again.

Similarly, S401 may further include S401, and S600 may be followed by S601. Referring to the foregoing embodiment, details are not described herein again.

First, image information including a user's avatar is obtained by a camera of the foldable display device, and based on the face information in the image information, which screen is relatively stationary and which screen is relatively moved. Then, the image information of one of the sub-displays obtained by the camera is calculated by an imaging formula and a trigonometric function to obtain an angle between the two sub-display screens.
