The electronic switch and the remote control key provided by the embodiment of the present disclosure are explained below with reference to the drawings.
An embodiment of the present disclosure provides an electronic switch. Fig. 4 is a schematic structural diagram of an electronic switch according to an embodiment of the present disclosure. As shown in fig. 4, the electronic switch includes a first substrate 110, a second substrate 120, a liquid crystal layer 130 disposed between the first substrate 110 and the second substrate 120, a first electrode 140 disposed on a side of the first substrate 110 close to the liquid crystal layer 130, and a second electrode 150 disposed on a side of the second substrate 120 close to the liquid crystal layer 130. For example, as shown in fig. 4, the first substrate 110 and the second substrate 120 are arranged in a cell pair to form a liquid crystal cell, and liquid crystal molecules are filled in the liquid crystal cell to form a liquid crystal layer 130. The electronic switch comprises an antenna zone 101 and an optical zone 102 which are arranged side by side, wherein a first electrode 140 comprises a plurality of first sub-electrodes 142 positioned in the antenna zone 101 and a plurality of second sub-electrodes 144 positioned in the optical zone 102, and the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are respectively and correspondingly loaded with a plurality of same electrical signals; for example, the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are respectively applied with the same plurality of electrical signals, and the sequence of the plurality of electrical signals applied to each of the plurality of first sub-electrodes 142 is the same as the sequence of the plurality of electrical signals applied to each of the plurality of second sub-electrodes 144. In the antenna area 101, an antenna patch 160 is disposed on a side of the first substrate 110 away from the liquid crystal layer 130, a signal receiver 170 is disposed on a side of the second substrate 120 away from the liquid crystal layer 130, and the antenna patch 160, the signal receiver 170, and the liquid crystal layer 130 in the antenna area 101 are driven by an electric field generated by the plurality of first sub-electrodes 142 and the plurality of second electrodes 150 to receive an antenna signal. In the optical area 102, the electronic switch includes a light emitter 180 and a light receiver 190 disposed on a side of the first substrate 110 away from the liquid crystal layer 130 and a side of the second substrate 120 away from the liquid crystal layer 130, and the liquid crystal layer 130 in the optical area 102 is configured to direct a light beam emitted from the light emitter 180 to the light receiver 190 under an electric field generated by the plurality of second sub-electrodes 144 and the second electrode 150 when the signal receiver 170 receives a predetermined antenna signal.
In the electronic switch provided in this embodiment, the electronic switch can scan under the driving of the electric fields of the plurality of first sub-electrodes 142 and the second electrode 150 through the antenna patch 160, the signal receiver 170 and the liquid crystal layer 130 located in the antenna region 101, so as to receive the antenna signal; when the signal receiver 170 receives a predetermined antenna signal, the voltage on the plurality of first sub-electrodes 142 of the antenna area 101 is specific; at this time, the light emitter 180 can be controlled to emit a light beam, and since the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are respectively and correspondingly loaded with the same plurality of electrical signals, the voltage on the plurality of second sub-electrodes 144 of the optical zone 102 can generate a specific electric field, and at this time, the liquid crystal layer 130 of the optical zone 102 of the electronic switch guides the light beam emitted by the light emitter 180 to the light receiver 190 under the specific electric field generated by the plurality of second sub-electrodes 144 and the second electrode 150. Thus, the optical receiver 190 can send out an on or off signal, thereby enabling the electronic switch to be turned on and off. The electronic switch provides a new type of electronic switch by combining a liquid crystal optical phased array with a phased array liquid crystal antenna. In addition, the electronic switch is turned on and off through the antenna signal, and the electronic switch does not need to store the identity information of the user, so that the leakage of the identity information such as fingerprints and irises can be avoided. On the other hand, the electronic switch can be produced by manufacturing equipment of the liquid crystal display panel, additional manufacturing equipment is not needed, and the cost is low due to the integration degree.
For example, in some examples, since the plurality of first sub-electrodes and the plurality of second sub-electrodes are configured to be respectively loaded with the same plurality of electrical signals, when the plurality of first sub-electrodes drive the liquid crystal layer so as to receive the preset antenna signal, the plurality of second sub-electrodes drive the liquid crystal layer so as to deflect the light beam emitted by the light emitter to the light receiver.
For example, in some examples, as shown in FIG. 4, light emitter 180 is disposed on a side of first substrate 110 away from liquid crystal layer 130 and light emitter 190 is disposed on a side of second substrate 120 away from liquid crystal layer 130. Of course, the embodiments of the present disclosure include, but are not limited to, that the light emitter 180 may also be disposed on the side of the second substrate 120 away from the liquid crystal layer 130, and the light receiver 190 may also be disposed on the side of the first substrate 110 away from the liquid crystal layer 130.
For example, in some examples, the optical receiver may signal the latch to open or close, thereby opening or closing the latch. For example, the lock may include a door lock, a vehicle lock, and the like.
For example, in some examples, the first electrode is a drive electrode and the second electrode is a common electrode. The antenna zone and the optical zone of the electronic switch may share a common electrode.
For example, in some examples, as shown in fig. 4, the light emitter 180 and the light receiver 190 are spaced apart by a distance in a direction parallel to the first substrate 110, and the liquid crystal layer 130 located in the optical zone 102 can deflect the light beam emitted by the light emitter 180 to the light receiver 190 under an electric field of the plurality of second sub-electrodes 144 and the second electrode 150 when the signal receiver 170 receives the predetermined antenna signal. Since the optical transmitter 180 and the optical receiver 190 are spaced apart by a distance in a direction parallel to the first substrate 110, the optical beam emitted from the optical transmitter 180 cannot enter the optical receiver 190 without the plurality of second sub-electrodes 144 being energized; also, when the signal receiver 170 receives an antenna signal other than the above-described antenna signal of a specific frequency and phase, the light beam emitted from the light emitter 180 cannot be directed to the light receiver 190, so that the safety of the electronic switch can be improved.
Fig. 5 is a schematic diagram of another electronic switch provided in accordance with an embodiment of the present disclosure. As shown in fig. 5, the electronic switch further includes a driver 195 and a controller 197. The driver 195 is connected to the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144, respectively, and drives the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144; the controller 197 is in communication with the driver 195, the signal receiver 170 and the optical transmitter 180, respectively; the controller 197 may control the driver 195 to maintain a current driving signal and control the optical transmitter 180 to transmit an optical beam when the signal receiver 170 receives the preset antenna signal.
In the electronic switch provided by the present embodiment, the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are driven by the driver 195, and the electronic switch can scan under the driving of the electric fields of the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 150 through the antenna patch 160, the signal receiver 170, and the liquid crystal layer 130 located in the antenna region 101, so as to receive the antenna signal; when the signal receiver 170 receives the predetermined antenna signal, the controller is controlled by 197 the driver 195 to maintain the current driving signal and control the light emitter 180 to emit the light beam, and since the first sub-electrodes 142 and the second sub-electrodes 144 are respectively loaded with the same plurality of electrical signals, the voltage on the second sub-electrodes 144 of the optical zone 102 may generate a specific electric field, and at this time, the liquid crystal layer 130 of the optical zone 102 of the electronic switch directs the light beam emitted by the light emitter 180 to the light receiver 190 under the specific electric fields of the first electrode 140 and the second electrode 150. Thus, the optical receiver 190 can send out an opening or closing signal, thereby realizing the opening and closing of the electronic switch. The electronic switch provides a new type of electronic switch by combining a liquid crystal optical phased array with a phased array liquid crystal antenna. In addition, because the electronic switch is turned on and off through antenna signals, leakage of identity information such as fingerprints and irises can be avoided.
For example, in some examples, as shown in fig. 5, first electrode 140 and second electrode 150 are both transparent electrodes to facilitate transmission of the light beam emitted by light emitter 180.
For example, in some examples, the second electrode may be a plate electrode.
For example, in some examples, the material of the first electrode and the second electrode may be a transparent conductive material such as indium tin oxide.
For example, in some examples, the optical transmitter comprises a laser transmitter and the optical receiver comprises a laser receiver. Due to the good directivity of the laser, the precision is higher when the laser beam emitted by the light emitter is directed by the optical zone of the electronic switch to the light receiver. Therefore, when the light transmitter adopts a laser transmitter and the light receiver adopts a laser receiver, the electronic switch has higher precision and smaller volume.
For example, in some examples, as shown in fig. 5, the signal receiver 170 includes a radio frequency adapter 172 and a microstrip line 174 connected to the radio frequency adapter 172. The microstrip line 174 can transmit microwaves and has advantages of small volume, light weight, wide use frequency band, high reliability, low manufacturing cost, and the like. Therefore, the signal receiver 170 can receive the antenna signal through the radio frequency adapter 172 and the microstrip line 174, and the signal receiver 170 can be miniaturized.
For example, in some examples, the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are driven synchronously.
An embodiment of the present disclosure also provides a key fob. Fig. 6 is a schematic diagram of a key fob provided in accordance with an embodiment of the present disclosure. As shown in fig. 6, the key fob includes an electronic switch 100 and a signal transmitting terminal 200 provided in any of the examples of the above embodiments. The signal transmitting terminal 200 may transmit an antenna signal.
In the key fob provided in this embodiment, a user can transmit a predetermined antenna signal through the signal transmitting terminal 200, and the electronic switch 100 can scan under the driving of the electric fields of the plurality of first sub-electrodes 142 and the plurality of second electrodes 150 through the antenna patch 160, the signal receiver 170, and the liquid crystal layer 130 located in the antenna area 101, so as to receive the antenna signal; when the signal receiver 170 receives a predetermined antenna signal, the voltage on the plurality of first sub-electrodes 142 of the antenna area 101 is specific; at this time, the light emitter 180 can be controlled to emit a light beam, and since the plurality of first sub-electrodes 142 and the plurality of second sub-electrodes 144 are respectively and correspondingly loaded with the same plurality of electrical signals, the voltage on the plurality of second sub-electrodes 144 of the optical zone 102 can generate a specific electric field, and at this time, the liquid crystal layer 130 of the optical zone 102 of the electronic switch guides the light beam emitted by the light emitter 180 to the light receiver 190 under the specific electric fields of the first electrode 140 and the second electrode 150. Thus, the optical receiver 190 can send out an on or off signal, thereby enabling the electronic switch to be turned on and off. The key fob can provide a new type of key fob by means of the signal transmitting terminal 200 and the electronic switch 100. In addition, the electronic switch is turned on and off through the antenna signal, so that the leakage of identity information such as fingerprints and irises can be avoided. On the other hand, the electronic switch can be produced by manufacturing equipment of the liquid crystal display panel, additional manufacturing equipment is not needed, and the integration degree is high, so that the cost of the remote control key is low. It should be noted that the preset antenna signals transmitted by the signal transmitting terminals correspond to the preset antenna signals of the electronic switches one to one, and the preset antenna signals transmitted by different signal transmitting terminals are different.
Fig. 7 is a schematic diagram of a signal transmitting terminal in a key fob according to an embodiment of the disclosure. As shown in fig. 7, the signal transmitting terminal 200 includes a signal transmitting module 210 and an identity recognizing module 220; the signal transmitting module 210 may transmit an antenna signal; the identification module 220 is communicatively connected to the signal transmitting module 210 and can identify a user to control whether the signal transmitting module 210 transmits an antenna signal. Therefore, the user can perform identification through the identification module 220, and transmit the antenna signal through the signal transmission module 210 after the user passes the authentication. Because the electronic switch can be usually arranged in the lockset, and the user can carry the signal transmitting terminal, the identity recognition module can store the identity information and the biological characteristic information of the user, and the identity information and the biological characteristic information of the user do not need to be stored in the electronic switch. Therefore, the remote control key can further avoid the leakage of the identity information and the biological characteristic information (such as fingerprints and irises) of the user, and the safety of the remote control key can be further improved.
For example, in some instances, as shown in fig. 7, the identity recognition module 220 may include one or more of a fingerprint recognition module, an iris recognition module, and a face recognition module to enable identification of the identity of the user. Of course, the embodiments of the present disclosure include, but are not limited to, the identification module may further include other identification devices.
For example, in some examples, signal transmitting end 200 may be a cell phone. With the coming of the 5G era, the function of transmitting antenna signals by mobile phones is also stronger and stronger. Therefore, when the signal transmitting end is a mobile phone, the function of transmitting the preset antenna signal can be improved. On the other hand, the signal transmitting terminal is a mobile phone, so that the mobile phone is convenient for a user to carry and use.
An embodiment of the present disclosure further provides a driving method of an electronic switch, where the electronic switch includes the electronic switch described in any one of the above descriptions, and the driving method includes: correspondingly loading a plurality of same electric signals on the plurality of first sub-electrodes and the plurality of second sub-electrodes respectively so that the antenna patches, the signal receivers and the liquid crystal layer positioned in the antenna area receive the antenna signals under the electric fields generated by the plurality of first sub-electrodes and the plurality of second sub-electrodes; and when the signal receiver receives the preset antenna signal, the liquid crystal layer positioned in the optical area is configured to guide the light beam emitted by the light emitter to the light receiver under the electric field of the plurality of second sub-electrodes and the second electrode.
Therefore, the optical receiver can send out an opening or closing signal, so that the electronic switch is opened and closed. In addition, because the opening and closing can be realized through the antenna signal, the electronic switch does not need to store the identity information of the user, and the leakage of the identity information such as fingerprints and irises can be avoided.
In the embodiments of the present disclosure, the above-described driver, controller, and respective modules may be implemented in software so as to be executed by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be constructed as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different physical locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
