[0074] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described below by way of example do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0075] In order to solve the above technical problems, the present disclosure provides a display control method. Figure 1 The present invention is a flow chart of a display control method according to an exemplary embodiment, which is applicable to an electronic device, wherein the electronic device may include a smart phone, a personal computer, or a server, etc. The electronic device includes a touch sensor, a display screen, and a biometric sensor disposed under the display screen, wherein the size of the biometric sensor exceeds a preset size.

[0076] The touch sensor may include at least one of the following: a touch-sensitive display screen, a pressure sensor, an infrared sensor, and a light sensor. The touch sensor may collect touch signals according to a preset period and send the touch signals to a processor of an electronic device. When the touch sensor is a touch sensor, the touch signal may be a floating touch signal. The processor may identify the attribute information of the touch signal and obtain sensing data; wherein the attribute information may include at least one of the following: the size, quantity, and characteristics of the touch signal. For ease of understanding, the schemes of each embodiment are described below using a touch-sensitive display screen (commonly referred to as a capacitive touch screen or capacitive screen) in which a capacitive sensor is set in the display screen.

[0077] The biometric sensor may include a fingerprint sensor, an iris sensor, and an auricle sensor. The following describes the solutions of various embodiments by taking the biometric sensor as a fingerprint sensor as an example.

[0078] See also Figure 2 , a display control method, applied to an electronic device, may include steps 21 to 23:

[0079] In step 21, at least one frame of sensing data representing the movement of a target object relative to an electronic device is acquired.

[0080] In this embodiment, it can be achieved through a capacitive screen. The working principle of the capacitive screen is briefly described as follows: the capacitive screen establishes a uniform electric field on the display screen. When the finger approaches or touches the display screen, a capacitance will be added to the display screen. The current emitted by the electrodes on the four sides of the display screen will flow to the contact point. Since the strength of the current is proportional to the distance from the finger to the electrode, the position of the contact point can be calculated based on the current on the four electrodes. Based on this principle, the capacitive screen can collect a frame of touch signals according to a preset period and send it to the processor in the electronic device or store it in the local memory.

[0081] The processor in the electronic device can communicate with the capacitive screen or local memory to obtain the touch signal. Then, the processor can process the touch signal. For example, by processing each frame of touch signal, the size, position or characteristics (such as left, right, etc.) of the target object approaching or touching the contour can be obtained, that is, a frame of sensing data can be obtained. For example, by processing several consecutive frames of touch signals, the movement speed, position, movement direction and other characteristics of the target object relative to the capacitive screen can be identified, thereby obtaining a frame of sensing data. Among them, the closer the acquisition time of each frame of touch signal is to the latest touch signal that the capacitive screen can sense, the better it can reflect the movement of the target object relative to the electronic device.

[0082] In this example, a circular storage area can be pre-set in the local memory, and the circular storage area can be divided into at least one sub-unit, and then a frame of sensor data is stored in each sub-unit in sequence according to the order of acquisition time. When the last sub-unit is stored, the next frame of sensor data will overwrite the sensor data in the first sub-unit, and so on. In this way, the processor can read the circular storage area once at a set time interval or whenever the sensor data is updated in the memory to obtain the required sensor data.

[0083] In step 22, the area to be identified on the electronic device is predicted based on the sensing data.

[0084] In this embodiment, the processor can predict the area to be identified based on the sensor data obtained in step 21. The area to be identified refers to an area in the display screen used to display preset information, and the preset information is used to indicate the biometric information of the target object to be identified, such as instructing the user to press the finger to the area to be identified to collect fingerprint information. The preset information may include one or more of the following: fingerprint icons, light spots, and boundaries of the area to be identified, etc., which can be set according to specific scenarios. For example, the above preset information may include a fingerprint icon or a boundary of the area to be identified, which is suitable for scenarios where the fingerprint sensor is implemented using a capacitive sensor or an ultrasonic sensor; for example, in addition to the fingerprint icon and the area to be identified, the above preset information may also include a light spot, which is suitable for scenarios where the fingerprint sensor is implemented using an optical sensor.

[0085] In one embodiment, the target object can be Figure 3 The method of controlling the display screen from far to near (non-contact) shown in the figure, wherein the finger moves from point A to point B, point C is the predicted target position, and the area to be identified 11 is generated with point C as the center position, which can be applicable to the scene where the touch sensor in the electronic device is a touch-sensitive display screen, an infrared sensor or a light sensor. Figure 4, at this time, predicting the area to be identified may include: in step 41, the processor may predict the target position where the target object contacts the electronic device based on the sensing data. The target object may be the fingertips of a human finger, the fingertips of a human toe, or the nose tip area of ​​a cat / dog, etc., and the target object includes a biological feature that can uniquely reflect the target object. In step 42, the processor may determine the area to be identified based on the target position. The size of the area to be identified may be set according to the area of ​​a preset part of the target object. For example, when the preset part is the fingertips of a finger, the area of ​​the area to be identified may be greater than or equal to the area of ​​the thumb tip, so as to facilitate accommodating each finger in the palm of the user.

[0086] In step 42, determining the area to be identified may include the following methods:

[0087] Method 1: The preset shape and preset size of the area to be identified can be pre-stored in the electronic device. The preset shape can be one of a circle, a rectangle and an eye shape. The above preset size is used to determine the size of the area to be identified, and can be set according to the size of the target object. After determining the target position, an area with a preset size and a preset shape can be obtained with the target position as the center, and the area of ​​the preset shape is determined as the area to be identified. For example, the preset shape is a circle, and the preset radius is R, then a circle can be obtained based on the target position and the preset radius R, and the figure is the area to be identified.

[0088] Method 2, see Figure 5 In step 51, the processor can obtain multiple sub-areas (such as 3000 pixels * 600 pixels) contained in the target area on the electronic device, as well as the center position of each sub-area. The target area is an area on the electronic device that can display the preset information. For example, the target area can be a display area on the display screen that is directly opposite to the fingerprint sensor 12, and the sub-areas can be obtained by dividing the above target area. The division method can be regular division or random division, and the center position of each sub-area has been determined during the division. For example, if the sub-area is divided regularly, the intersection position of the diagonal line can be used as the center position of each sub-area; for example, if the sub-area is divided irregularly, the center of gravity position of the sub-area can be used as the center position of each sub-area. In step 52, the processor can obtain the distance between the target position and the center position of each sub-area. The above distance can be the Euclidean distance, and the distance between the two points can be calculated according to the coordinates of the target position and the center position and the Euclidean distance calculation formula. In step 53, the processor can sort all sub-areas according to the distance size, and determine the sub-area corresponding to the smallest distance as the area to be identified.

[0089] Method 3: The processor can obtain multiple sub-regions contained in the target area and the center position of each sub-region. The method for obtaining the above multiple sub-regions can refer to the above step 51. Then, the processor can predict which sub-region the target object falls into, and the sub-region it falls into is the area to be identified.

[0090] In another embodiment, the target object can be Figure 6 The display screen is operated by sliding from one side to the other side (contact), wherein the finger slides from point A to point B, point C is the target position selected on the moving trajectory, and the area to be identified 11 is generated with point C as the center position. This can be applied to the scenario where the touch sensor in the electronic device is a touch-sensitive display screen, a pressure sensor, an infrared sensor or a light sensor. Figure 7 , determining the target position at this time may include: in step 71, the processor may determine the historical movement trajectory and current movement direction of the target object according to the sensor data. For example, the processor may determine the position of the target object according to each frame of sensor data, and may obtain a historical movement trajectory and current movement direction of a section of the sliding according to the position of a certain position of the target object in multiple frames of continuous sensor data (including the sensor data collected at the current time) and the collection time. The historical movement trajectory is as follows: Figure 6 In step 72, the processor predicts a non-sliding target movement trajectory based on the historical movement trajectory and the current movement direction. The target movement trajectory is as follows: Figure 6 In step 73, the processor may determine the target position based on the target moving trajectory. For example, the processor may select a point on the target moving trajectory that is a certain distance from the target object as the target position. The specific method of determining the area to be identified based on the target position is the same as step 42, which will not be repeated here.

[0091] In step 23, preset information is displayed in the area to be identified, where the preset information is used to indicate biometric information for identifying the target object.

[0092] In this embodiment, the processor can control the display screen to display preset information in the area to be identified, such as displaying an icon and / or a light spot for indicating the entry of biometric information in the area to be identified, the effect is as follows: Figure 3 and Figure 6As shown. In this way, when the user touches the display screen, the preset information can be immediately displayed in the area to be identified; or, after predicting the position to be identified in advance, the preset information can be displayed first, and then the user (for example, finger) does not need to judge the display position of the preset information when it falls until it touches the screen (just fall naturally), or, it only needs to make slight adjustments in the direction of its natural fall (refer to the display position of the preset information) to fall into the area to be identified. The fingerprint sensor located under the display screen can collect fingerprint information (i.e., biometric information). After collecting the fingerprint information, the processor can also match it with the pre-stored fingerprint module to realize functions such as fingerprint information entry, fingerprint unlocking, and payment matching.

[0093] At this point, in the disclosed embodiment, at least one frame of sensing data indicating the movement of the target object relative to the electronic device can be obtained; the area to be identified on the electronic device can be predicted based on the sensing data; and preset information can be displayed in the area to be identified, wherein the preset information is used to indicate the biometric information for identifying the target object. In this way, in this embodiment, the area to be identified can change dynamically with the sensing data, and the target object does not need to enter the biometric information at a fixed preset position, which is conducive to improving the experience of using the information entry function; and the preset information can be displayed in the area to be identified earlier than the time when the target object arrives at the area to be identified, thereby achieving the effect of guiding the target object to press the preset information, further improving the experience of using the information entry function.

[0094] The following describes the above display control method in combination with an embodiment in which a user uses a mobile phone to implement fingerprint unlocking, including:

[0095] The mobile phone is equipped with a large-area fingerprint sensor. The target area of ​​the display screen corresponding to the fingerprint sensor is divided into several sub-areas in advance. The size of each sub-area can be set to 3000 pixels * 600 pixels. Figure 8 The positions where the two preset information (fingerprint icon and light spot) light up are shown. If the finger falls within the range AB, the fingerprint icon and light spot will be displayed in area A; if the finger falls between BC, the fingerprint icon and light spot will be displayed in area B.

[0096] When the user picks up the phone, the effect is like Fig. 9 As shown in Figure (a), the processor can distinguish between the left hand and the right hand based on the sensor data collected by the capacitive screen, predict the position to be identified, light up the fingerprint icon and light spot in the corresponding area, and guide the user to unlock. The effect is as follows: Fig. 9 As shown in Figures (b) and (c), Figure (b) shows a solution in which the fingerprint icon and light spot are displayed in area A, and Figure (c) shows a solution in which the fingerprint icon and light spot are displayed in area B.
