Example one
An embodiment of the present invention provides an antenna switching method for a multi-screen folding terminal, and as shown in fig. 1, the method includes:
s101, detecting the working state of each screen provided with a first type antenna in the terminal;
s102, switching the antenna switching state of the first type antenna on a screen in a working state according to the signal interference condition existing between the first type antennas; the respective screens include a main screen and at least one auxiliary screen.
According to the embodiment of the invention, the antenna switching state of the first type antenna on the screen in the working state is switched by detecting the working state of each screen of the terminal and the signal interference condition existing between the first type antennas, so that the performance of the first type antenna can be changed along with the change of a use scene, and the randomness and the activity of the first type antenna can be realized; and the effective radiation space after the multiple screens are unfolded can be utilized, so that the maximization of the antenna radiation efficiency is ensured, and the antenna signal intensity of the multi-screen mobile terminal is effectively improved.
In detail, the multi-screen folding terminal in the embodiment of the present invention may be simply referred to as a terminal. The antenna switch state in the embodiment of the present invention includes an on state and an off state, where the off state may also be referred to as a switch-off state.
For example, as shown in fig. 2, the terminal includes 2 screens foldable to each other, wherein 2 first-type antennas Ant1 and Ant2 are disposed on the screen 1, and 1 first-type antenna Ant3 is disposed on the screen 2. Where screen 1 may be the primary screen and screen 2 may be the secondary screen.
As another example, as shown in fig. 3, the terminal includes 3 screens, where the screen 1 and the screen 2 are foldable with each other, and the screen 1 and the screen 3 are foldable with each other; wherein 2 first type antennas Ant1 and Ant2 are disposed on the screen 1, and 1 first type antennas Ant3 and Ant4 are disposed on the screen 2 and the screen 3, respectively. Where screen 1 may be the primary screen and screens 2 and 3 may be the secondary screens.
In the embodiment of the invention, optionally, any auxiliary screen can rotate around the preset axis of the main screen to open and close relative to the main screen, so that the mutual folding effect is achieved. The preset axis may be a physical rotation axis or a virtual axis.
In the embodiment of the present invention, optionally, the first type antenna belongs to a radio frequency signal antenna, which may also be referred to as a mobile terminal antenna or a mobile phone antenna, and is generally used for receiving or radiating radio frequency signals; which may include wireless communication signals and communication signals that interact with base stations.
According to the embodiment of the invention, the first type antenna is arranged on the auxiliary screen, and the design of a conventional fixed mode antenna is changed, so that the performance of the first type antenna can be changed along with the change of a use scene, and the randomness and the activity of the first type antenna can be realized; and the effective radiation space after the multiple screens are unfolded can be utilized, so that the maximization of the antenna radiation efficiency is ensured, and the antenna signal intensity of the multi-screen mobile terminal is effectively improved.
In the embodiment of the present invention, optionally, the main screen may be preset to be always in a working state; the working state of the auxiliary screen can be switched. The main screen may also be referred to as a main screen, and the auxiliary screen may also be referred to as an auxiliary screen. For example, a screen at a main board side of the mobile terminal is set as a main screen, and the remaining screens are referred to as auxiliary screens. The connection relationship between the main screen and the auxiliary screen in the embodiment of the present invention may be implemented by using the prior art, as long as the folding effect can be achieved, and therefore, the present invention is not limited specifically herein.
In the embodiment of the present invention, optionally, the first type antenna on the main screen is disposed at a first end (upper end) and a second end (lower end) of the back of the main screen; the first type antenna on the auxiliary screen is arranged at the first end or the second end of the back of the auxiliary screen; wherein the first end may be an upper end and the second end may be a lower end.
For example, one end of the terminal is designated as the upper end, and the other end of the terminal is designated as the lower end; as shown in fig. 2, the positions at which Ant2 and Ant4 are disposed belong to the upper ends, and the positions at which Ant1 and Ant3 are disposed belong to the lower ends.
In the embodiment of the present invention, optionally, in two adjacent auxiliary screens provided with the first type antenna, the first type antenna of one of the auxiliary screens is disposed at the upper end of the auxiliary screen, and the first type antenna of the other of the auxiliary screens is disposed at the lower end of the auxiliary screen. Where neighbors include direct neighbors and indirect neighbors across the home screen.
For example, as shown in fig. 3, Ant3 and Ant4 are provided at the upper and lower ends.
In an embodiment of the present invention, optionally, the first type antenna on the secondary screen is etched on the panel of the secondary screen by a Flexible Circuit board (FPC) process or a Printing Direct Structure (PDS) process.
In the embodiment of the present invention, optionally, the terminal further includes a radio frequency circuit module; and the first type antenna on the auxiliary screen is connected with the radio frequency circuit module through a coaxial line.
In the embodiment of the present invention, optionally, a second type antenna for short-range wireless communication is disposed on at least one of the auxiliary screens. Wherein the second type of antenna may be a Near Field Communication (NFC) antenna.
In the embodiment of the present invention, the terminal may be a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, an intelligent bracelet, and a pedometer.
For example, in a conventional mobile phone antenna design, the mobile phone antennas are distributed at two ends of the main screen of the mobile phone. However, since devices such as a battery, a PCB (Printed Circuit Board) main Board, a daughter Board, and the like are placed on the back of the main screen, the surrounding environment is complicated, and thus the antenna radiation space is small.
Because the auxiliary screen is basically formed by attaching an LCD (Liquid Crystal Display) and a touch screen, no PCB (printed circuit board) is arranged at the back of the screen and at the bottom of the top end of the screen, and no battery is arranged. Therefore, in the embodiment of the present invention, the first type antenna may be disposed in the upper end region and/or the lower end region of the auxiliary screen, and the communication signal may be transmitted to the antenna port of the first type antenna through the coaxial line, so that the first type antenna on the auxiliary screen may be started according to the operating state of the auxiliary screen, thereby effectively improving the antenna signal strength of the multi-screen mobile terminal.
The embodiment of the invention is suitable for a double-sided or three-sided folding screen mobile terminal, and is a schematic diagram of the mobile terminal with a main screen and an auxiliary screen as shown in figure 2. As shown in fig. 3, a mobile terminal having one main screen and two sub-screens is schematically illustrated. When the auxiliary screen is unfolded for use, an excellent antenna radiation environment can be provided, so that the first type antennas Ant3 and Ant4 can be switched for use according to an application scene, and the problem of signal deterioration of the multi-screen folding mobile terminal is effectively solved.
In this embodiment of the present invention, optionally, before switching the antenna switching state of the first type antenna on the screen in the working state according to the signal interference condition existing between the first type antennas, the method includes:
and determining that the position relation between the screens in the working state reaches a preset switching threshold value.
Wherein the position relationship is an included angle between the main screen and the auxiliary screen; the handover threshold may be a handover angle threshold.
For example, the operating states of the main screen and the auxiliary screen may be determined by a preset LCD control discrimination module.
In the embodiment of the invention, the included angle between the auxiliary screen and the main screen is detected, and when the included angle reaches the preset switching angle threshold value, the first type antenna on the auxiliary screen is started, so that invalid antenna switching can be effectively avoided, and the antenna signal intensity of the multi-screen folding terminal is further improved.
For example, the angle between the main screen and the auxiliary screen is small, such as 5 degrees, and the radiation space formed by the main screen and the auxiliary screen is relatively small, so that no switching is required. The threshold value of the switching angle may be 30 degrees, and of course, in the embodiment of the present invention, the maximum included angle between the main screen and the auxiliary screen may also be set to be 180 degrees.
For another example, in the embodiment of the present invention, the angle between the auxiliary screen and the main screen may be detected by an angle detector module preset in the main screen and/or each auxiliary screen. Wherein the angle detector module may be a spindle angle detector module.
In this embodiment of the present invention, optionally, the switching the antenna switch state of the first type antenna on the screen in the working state according to the signal interference condition existing between the first type antennas includes:
if the screen that is in operating condition does main screen and an auxiliary screen, will first type antenna on the first end of main screen and this auxiliary screen second end switch into the open mode, will first type antenna on the main screen second end switches into the closed mode.
If the screen that is in operating condition does main screen and two are assisted the screen, will the first type antenna that main screen first end and second held switches into the off-state, will set up and switch into the on-state at the first type antenna on two assistance screens of different ends.
Wherein, if the screen that is in operating condition does main screen and two subsidiary screens, will the first type antenna that main screen first end and second end were held switches into off-state, and the first type antenna that will set up on two subsidiary screens of different ends switches into on-state, optionally includes:
judging whether the main screen and the two auxiliary screens form a preset graph or not;
if so, detecting the signal intensity of the first type antenna on the screen in the working state, and switching the first type antennas on the main screen and the two auxiliary screens into an open state or a closed state according to the signal intensity;
if not, the first type antennas on the first end and the second end of the main screen are switched to be in an off state, and the first type antennas on the two auxiliary screens at different ends are switched to be in an on state.
Wherein, judge the main screen with the mode that two subsidiary screens constitute preset graphics, optionally, include:
detecting a positional relationship between the main screen and the two auxiliary screens;
and judging that the graph formed between the main screen and the two auxiliary screens is matched with a preset graph according to the position relation.
The optional embodiment of the invention can effectively solve the problem that the first type antennas of the main screen and the auxiliary screen interfere with each other, thereby further improving the antenna signal strength of the multi-screen mobile terminal.
As shown in fig. 2, the first type antennas Ant3 and Ant1 both belong to the lower end, and have signal interference, so they cannot be activated simultaneously; similarly, the first type antennas Ant2 and Ant4 belong to the upper ends, and signal interference exists, so that the first type antennas Ant2 and Ant4 cannot be started at the same time.
In the embodiment of the invention, the first type antenna of the main screen is in an open state under the default condition, so that in the embodiment of the invention, when the first type antenna of the auxiliary screen is started, the corresponding first type antenna in the main screen is cut off according to the antenna interference condition, and the first type antenna of the main screen and the first type antenna on each auxiliary screen in a working state can achieve multiple working combinations.
For example, when the multi-screen is judged to be in the folding state, only the main screen works at the moment, and the antenna switches of Ant1 and Ant2 are set to be on; the antenna switches of Ant3 and Ant4 are set to off.
For another example, when it is determined that the dual screen is operated, and it is determined that the screen 1 (main screen) and the screen 2 (auxiliary screen) are operated, the antenna switches of Ant2 and Ant3 may be set to on; the antenna switches of Ant1 and Ant4 are set to off.
As another example, when it is judged that the dual screen operation is performed, and it is judged that the screen 1 (main screen) and the screen 3 (auxiliary screen) are operated, the antenna switches of Ant1 and Ant4 may be set to on; the antenna switches of Ant2 and Ant3 are set to off.
If the three screens are unfolded and do not form a preset pattern, as shown in fig. 3, the antenna switches of Ant3 and Ant4 may be set to be on; the antenna switches of Ant1 and Ant2 are set to off. In the embodiment of the present invention, the preset pattern may be a three-sided figure as shown in fig. 4 and an N-shaped three-dimensional figure as shown in fig. 5. In the figure, screen 1 may be a main screen, and screen 2 and screen 3 may be two sub-screens.
In the embodiment of the invention, the antenna can be switched on and off through the antenna switch selector. As shown in fig. 2, if the first type antenna Ant4 is activated, the antenna switch selector may be controlled to set the antenna switch of the first type antenna Ant4 to the on state on; if the first-type antenna Ant2 is blocked, the antenna switch selector can be controlled to set the antenna switch of the first-type antenna Ant2 to the off state off.
In this embodiment of the present invention, optionally, after switching an antenna switching state of the first type antenna on the screen in the working state according to a signal interference condition existing between the first type antennas, the method includes:
and calling a preset antenna tuning value to perform signal compensation on the first type antenna in the open state.
Wherein, the invoking a preset antenna tuning value, before performing signal compensation on the first type antenna in the on state, optionally includes:
and setting the antenna tuning value according to a combined mode formed by the first type of antenna in the opening state.
In detail, the method in the embodiment of the present invention may be implemented by a control circuit as shown in fig. 6, where the control circuit may include:
and the LCD control discrimination module (or control discrimination module) is used for discriminating the working state of each screen.
And the angle detector module adopts sensing equipment and is used for detecting included angles among the screens.
And the Radio Frequency (RF) circuit module is used for carrying out interaction and processing of information transmitted and received by Radio Frequency.
And the processing unit module is used for coordinating various software and hardware signal interaction instructions and controlling the connection of each module and task processing.
And the signal discriminator module is used for discriminating and comparing the signals of the antenna under special use conditions so as to perform selective switching. For example, in the case where the auxiliary screen and the main screen constitute a preset stereoscopic graphic.
And the antenna switch selector module is used for setting the state of each antenna switch and selecting the working mode according to the instruction of the control unit.
And the matching fine tuning calibration module is used for compensating the deterioration of signals in time by adopting matching fine tuning calibration, wherein the antenna frequency offset can be caused by certain use scenes under the condition that the antenna is not switched.
Taking a three-screen folding terminal as an example, as shown in fig. 7, L0 in the figure is a main screen, and the main screen is always in a pass-through use state, and L0 is 1.
L1 is auxiliary screen 1, and default L1 is 0, i.e. the first type antenna of auxiliary screen 1 is off. If L1 is equal to 1, the first type antenna of the auxiliary screen 1 is switched to the on state.
L2 is the auxiliary screen 2, and default L2 is 0, i.e. the first type antenna of the auxiliary screen 2 is off. If L2 is equal to 1, the first type antenna of the auxiliary screen 2 is switched to the on state.
The angle 1 is an included angle between the auxiliary screen 1 and the main screen, the angle 2 is an included angle between the auxiliary screen 2 and the main screen, and the two included angles are larger than 0 degree and smaller than 180 degrees.
S1, S2, S3 and S4 are antenna switches of the four groups of antennas shown in fig. 3, respectively.
When the state of each antenna switch is 1, the antenna switch is turned on, and the corresponding antenna is in a turn-on state to start working;
when the state of each antenna switch is 0, the antenna switch is turned off, and the corresponding antenna is turned off to cut off the operation.
SiAnd the antenna signal strength is used for judging and comparing the antenna signal. An antenna matching tuning module capable of being slightly changed according to user useAnd performing antenna tuning compensation under the same use condition. In specific implementation, the configuration can be performed in software in advance, and the preset antenna tuning value is called.
Optionally, as shown in fig. 8, the method implemented by the control circuit in the embodiment of the present invention includes:
step 1, the LCD control and discrimination module determines the working states of the main screen and the auxiliary screen, identifies the states of L0, L1 and L2, and sends the states of L0, L1 and L2 to the processing unit module. Since the main screen is a core device of the entire mobile terminal, L0 may be always set to 1.
And 2, detecting the < 1 and the < 2 by an angle detector module and sending the detected values to a processing unit module.
Step 3, the processing unit selects the branch of execution according to the states of L0, L1 and L2; branch 1 is executed if L1 equals 0 and L2 equals 0; branch 2 is executed if L1 is 1 and L2 is 0; branch 3 is executed if L1 ═ 0 and L2 ═ 1; branch 4 is executed if L1-L2-1.
In the embodiment of the invention, whether the first type antenna is switched or not is also configured according to the included angle between the auxiliary screen and the main screen, wherein the included angle is measured by the auxiliary screen angle detector. Setting 30 degrees as the open-close restriction condition, less than 30 degrees, the auxiliary screen assumes the folded state, in which case the switching is meaningless. After the first type antenna is switched and the state of the antenna is stable, the antenna matching tuning module can be called at any time to perform signal micro-compensation.
It is therefore possible to continue to determine the angle between the main screen and the auxiliary screen in each branch, and then further determine the use states of the first-type antennas of the main screen and each auxiliary screen according to the angle.
In branch 1, the conventional folded state used by the three-screen mobile terminal, in which the first type antennas are generally distributed in the upper and lower end regions of the main screen, is set that Ant1 is the main antenna of the main screen domain and Ant2 is the auxiliary antenna of the main screen. All antenna connection points of the antennas Ant3 and Ant4 on the auxiliary screen are disconnected, and the antennas are made into suspended metal wires. When the three-screen mobile terminal is folded and closed, only the main screen works, and at the moment, Ant3 and Ant4 have no obvious influence on the main antenna. The generated micro frequency offset can be subjected to micro compensation through a software self-tuning module.
In branch 2, the dual-screen operation, i.e. the operation of one auxiliary screen plus one main screen, has a problem of isolation due to the too close distance between Ant1 and Ant3, and the two are not recommended to work together, plus the environment of Ant3 is excellent, i.e. S1-S4-0 and S2-S3-1 are set.
In branch 3, S1-S4-1 and S2-S3-0 are set.
In branch 4, three screens are operated, that is, two auxiliary screens are operated, and since there is no obvious metal device nearby and the antenna environment is better when the auxiliary screens are operated, Ant1 and Ant2 are switched off and Ant3 and Ant4 are operated. Of course, in the branch 4, there are also special cases, for example, as shown in fig. 4, three LCDs are placed in a stereoscopic manner, that is, the angle 1 is 60 degrees, or as shown in fig. 5, N-shaped LCD appears, and at this time, the optimum two groups can be selected for operation by performing discrimination according to the use scene, the hand-held scene, and the like.
It should be noted that, in the embodiment of the present invention, Ant1 and Ant3 cannot operate simultaneously, Ant2 and Ant4 cannot operate simultaneously, and if the antennas are too many separated, this may also be the case, for example, antennas at the same end cannot be used simultaneously.
Of course, in the embodiment of the present invention, the three-screen mobile terminal has various usage scenarios, and may also be allocated to multiple antennas, for example, Ant1 is a main antenna 1, Ant3 is a main antenna 2, Ant2 is a diversity antenna group, Ant4 is a GPS antenna, a diversity antenna group, and the like.
And 4, when the auxiliary screen is unfolded or closed, causing a small-range frequency offset to the main screen antenna, and compensating the part of frequency offset through adaptive tuning of the matching fine tuning calibration module.
In this embodiment of the present invention, optionally, the method further includes:
detecting that the terminal carries out short-distance wireless communication;
determining an auxiliary screen which is not in a working state from the auxiliary screens provided with the second type antennas;
