DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. The embodiment of the present invention provides a method for controlling a screen of a terminal during a call. FIG. 1 is a flowchart of a method for controlling a screen of a terminal during a call according to an embodiment of the present invention. As shown in FIG. 1 , the method includes the following steps S102 to Step S106. Step S102: Acquire an initial state value of the terminal when answering the call. Step S104: Acquire a current state value of the terminal during the call. Step S106, controlling whether the screen of the terminal accepts the input according to the initial state value and the current state value. In the related art, the screen of the terminal is controlled by a physical button during the call, and the user is required to perform a certain operation or the use condition is limited, and the requirement cannot be completely satisfied. In the embodiment of the present invention, by determining the current state value of the terminal during the call and the change of the initial state value of the terminal when answering the phone, the screen of the terminal is controlled to accept input, thereby avoiding contact of the face or other parts during the call. The resulting misoperation. Step S104 includes: determining that the current call has not ended; acquiring the current state value of the terminal according to a predetermined frequency. In the preferred embodiment, in the case that the current call is not finished, the current state value of the terminal is acquired every time interval, so that the terminal value can be compared with the initial value in time to prevent the erroneous operation. Step S106 includes: calculating a difference between the current state value and the initial state value; if the difference is not less than a preset threshold, the screen of the control terminal is in the off state, and continues to acquire the current state value of the terminal; The preset threshold value controls the terminal's screen to be lit, accepts input, and continues to acquire the current state value of the terminal. In the preferred embodiment, a specific implementation manner of controlling the screen of the terminal by using the initial state value and the current state value is provided, and the difference between the two is compared with a predetermined value to control the screen of the terminal, and the result of the control is relatively reliable. . After the screen of the control terminal is in the lighting state, the user's input is accepted. At this time, the state value of the terminal needs to be continuously obtained. Once the requirement is met, the user needs to pick up the terminal to continue the call, and the screen needs to be extinguished. Preferably, the state value of the terminal includes a screen tilt angle which is an angle parallel to the axis of the side edge of the terminal and the vertical direction. Preferably, the state value of the terminal further includes a screen orientation, and the screen orientation is an angle perpendicular to an axis of the screen plane of the terminal and a vertical direction. In the preferred embodiment, the terminal screen is controlled using two values of the screen tilt angle and the screen orientation, and the result is more accurate. Preferably, acquiring the status value of the terminal comprises: acquiring an inclination angle of the screen of the terminal by using an acceleration sensor in the terminal. The acceleration angle sensor originally provided in the terminal is used to obtain the tilt angle of the screen, thereby avoiding the use of an external input device, and the acquisition method is also convenient. As can be seen from the above description, the embodiment of the present invention can control the terminal screen by the following steps: When the user starts to answer the call (can be a sliding answer, press the answer key, etc.), the value of the acceleration sensor is read and recorded as Initial value. Then, the value of the acceleration sensor is continuously read during the call and compared with the initial value. Through calculation, the angle between the initial value and the current value is obtained. If the angle meets a certain range, it means that the user does not accept input when the control terminal screen is off during the call; otherwise, the control terminal screen lights up and accepts the touch screen input operation. In this way, the tilt angle of the terminal screen is sampled by the acceleration sensor and compared with the initial position, and the command can no longer be received when the angle difference is greater than the preset value, thereby preventing the erroneous operation of the terminal screen. In order to make the technical solutions and implementation methods of the embodiments of the present invention clearer, the implementation process will be described in detail below in conjunction with the preferred embodiments. 2 is a flow chart of a method for controlling a screen of a terminal during a call according to a preferred embodiment of the present invention. The preferred embodiment describes a flow of controlling a screen of a terminal by a value collected by an acceleration sensor during a call and during a call, such as As shown in FIG. 2, the following steps S202 to S220 are included. Step S202, receiving an incoming call. Step S204, the user answers the call, can operate by touching the screen to answer the call, or can answer the call by pressing a button. In step S206, the value of the acceleration sensor at this time is recorded as the "initial value". In step S208, it is determined whether the call is over. If yes, step S210 is performed; otherwise, step S212 is performed. Step S210, the operation of stopping the acceleration sensor to acquire the value of the terminal is completed, and the flow ends. In step S212, the value of the acceleration sensor is taken once in a short interval, and is recorded as "current value". Step S214, the current value and the initial value are calculated to obtain an angle between the current position and the initial value position. Step S216, determining whether the angle is greater than a set threshold, if yes, executing step S218; otherwise, performing step S220. In step S218, it is determined that it is close, and the screen is turned off. In step S220, it is determined that it is not close, and the normal operation touch screen is accepted. As can be seen from the above preferred embodiment, when the user answers the call, the value of the acceleration sensor is recorded, and the corresponding screen orientation, the screen tilt angle, and the like are calculated as the initial value storage; during the entire process of the call, the acceleration is obtained. The value of the sensor calculates the current position of the terminal. Compare the above two values to see if the difference between the two is greater than the threshold. If it is greater than the threshold, turn off the screen. If it is less than the threshold, allow input through the touch screen. The tilt angle of the terminal in the embodiment of the present invention will be described below. The user can use the mobile terminal to answer the call in any posture, and when the mobile terminal answers the call and during the call, the position information of the mobile terminal such as the screen orientation and the tilt angle may be significantly different. When the user answers the call, the terminal is generally at an angle that is parallel to the horizontal plane or has a relatively small horizontal plane. For example, the user answers the call in an upright state, and the screen of the mobile terminal is upward when answering, the vertical direction (ie, the normal direction of the horizontal plane) and the acceleration z-axis of the terminal (ie, the axis perpendicular to the screen plane of the terminal) are substantially parallel, the terminal The acceleration y-axis (ie, the axis parallel to the side edge of the terminal, also known as the center axis) is perpendicular to the vertical direction. During the call, the screen orientation of the mobile terminal, the vertical direction and the acceleration z-axis have a distinct angle. 3 is a schematic diagram of a tilt state of a terminal during normal call according to a preferred embodiment of the present invention. As shown in FIG. 3, in general, when the user is in a call, the acceleration z-axis of the terminal has a certain angle with the vertical direction ( Representing the screen orientation), the acceleration y-axis of the terminal also has a certain angle with the vertical direction (representing the tilt angle of the screen). Compare the current value of the obtained call with the initial value when answering the call, and control whether the terminal screen accepts the input according to the comparison result, which can ensure that the user can normally control the screen after receiving the call in various postures, thereby minimizing the misoperation . 4 is a schematic flow chart of comparing an initial value with a current value according to a preferred embodiment of the present invention. As shown in FIG. 4, the following steps S402 to S420 are included. Step S402, calculating an initial screen orientation according to the initial value. Step S404, calculating an initial screen tilt angle according to the initial value, where the initial screen tilt angle refers to an angle between the central axis of the terminal and the vertical direction when the telephone is answered. Step S406, calculating a current screen orientation according to the current value. Step S408: Calculate the current screen tilt angle according to the current value. The current screen tilt angle refers to the angle between the center axis of the terminal and the vertical direction in the current situation when the call is not finished. Step S410, calculating a difference between the initial screen orientation and the current screen orientation. Step S412, calculating a difference between the initial screen tilt angle and the current screen tilt angle. In step S414, it is determined whether the difference between the initial screen orientation and the current screen orientation is greater than the threshold 1, and if so, step S416 is performed, otherwise step S420 is performed. Step S416, determining whether the difference between the initial screen tilt angle and the current screen tilt angle is greater than the threshold 2, and if yes, executing step S418, otherwise performing step S420. In step S418, it is determined that the call is in close proximity to the ear. In step S420, it is determined that there is no answer at the ear. The preferred embodiment shown in Fig. 4 takes into account variations in screen orientation and screen tilt angle, and control of the terminal screen is more accurate.
