Fig. 4 is a schematic structural diagram of another laser pointer 100 provided in the embodiment of the present application. The laser pen 100 comprises a pen holder 110, wherein the pen holder 110 is provided with an installation cavity with one open end; the laser generating device is arranged in the mounting cavity; the pen point 120 is arranged at the opening end of the pen holder 110 and is electrically connected with the laser generating device, the pen point 120 is provided with a pen point 121, and the pen point 121 is used for emitting laser emitted by the laser generating device; and the information exchange module is used for sending a request instruction to the light sensing screen 200 so that the light sensing screen 200 displays according to the request instruction and the received laser moving path.
Specifically, in the present embodiment, the barrel 110 is disposed in a cylindrical shape, and the cross section thereof may be circular, oval, square, triangular, or any other desired shape. The pen shaft 110 may have an opening at one end or two ends, and in some embodiments, the number of the pen points 120 may be one (installed on the opening at one end) or two (installed on the two openings, respectively), and specifically may be set according to requirements. The laser generator is used for generating laser and emitting the generated laser to the pen head 120. The pen tip 120 emits the laser generated by the laser generator. The information exchange module generates a request instruction to the light-sensing screen 200, which may be a request according to the control of the user, or a request sent by the laser pen 100 to the light-sensing screen 200 after detection according to the detection result. The content of the request command may be a request command transmitted to establish a connection, a request command transmitted to enter a specific mode, or the like. The information exchange module and the light sensing screen 200 may exchange information in many forms, such as bluetooth connection, infrared communication connection, wireless lan connection, and the like.
In this embodiment, through the configuration of the information exchange module, and the information exchange module is configured to send a request instruction to the light-sensing screen 200, so that the light-sensing screen 200 displays according to the request instruction and the received laser moving path, so that after the display screen receives the request instruction of the light-sensing screen 200, the laser pen 100 establishes a communication connection with the light-sensing screen 200, and enters a state where the laser pen 100 interacts with the light-sensing screen 200, the TFT of the light-sensing screen 200 has a light-sensing characteristic, when the laser of the laser pen 100 is incident on the light-sensing screen 200, a position irradiated by the laser generates a photo-carrier, so that an optical signal is converted into an electrical signal, a reading circuit of the light-sensing screen acquires coordinate information of the generated photo-carrier (laser), thereby implementing the reporting of the laser position, and then controlling the display screen to display at a corresponding position, thereby implementing a function that the laser pen 100 can write on the light-sensing screen 200, as such, the use of the laser pointer 100 by the user is more facilitated.
In some implementations, to further enhance the user experience, the laser pen 100 has a writing state and a wiping state, the master control circuit of the laser pen 100 includes a first trigger circuit and a second trigger circuit; in the writing state, the first trigger circuit is electrically connected with the laser generating device so as to enable the pen point 121 to emit laser with first intensity; in the wiping state, the second trigger circuit is electrically connected to the laser generator to enable the pen tip 121 to emit laser with a second intensity, wherein the first intensity is not equal to the second intensity.
Specifically, in this embodiment, the first trigger circuit and the second trigger circuit correspond to different trigger conditions or different trigger voltages, and the different conditions trigger the first trigger circuit or the second trigger circuit to be electrically connected to the laser generating device. Of course, in some embodiments, the laser pen 100 may include a switching trigger device for switching the connection of the first trigger circuit and the second trigger circuit to the laser generating device. The first intensity may be greater than the second intensity, and the first intensity may also be greater than the second intensity.
The first trigger circuit controls the laser generating device to excite laser with first intensity, and when the light sensing screen 200 receives the laser with the first intensity, the light sensing screen 200 generates photo-carrier intensity corresponding to the laser with the first intensity to generate a first electric signal. The light sensing screen 200 confirms that the current writing state is achieved according to the first electric signal, and the light sensing screen 200 displays the moving track of the laser on the light sensing screen 200 according to the position of the laser to form a writing trace.
The second trigger circuit controls the laser generating device to excite the laser with the second intensity, and when the light sensing screen 200 receives the laser with the second intensity, the light sensing screen 200 generates photo-carrier intensity corresponding to the laser with the second intensity to generate a second electric signal. The light-sensing screen 200 confirms that the laser is in the wiping state according to the second electric signal, and the light-sensing screen 200 eliminates the content written on the laser moving track.
So, through set up first trigger circuit and second trigger circuit in laser pen 100 to make laser generating device produce the laser of first intensity according to first trigger circuit, produce the laser of second intensity according to the second trigger circuit, so, make light sense screen 200 can enter into the writing state according to first intensity, enter into according to the second intensity and wipe the state, so, realize writing or wiping with laser pen 100.
Regarding the switching of the first trigger circuit and the second trigger circuit, the laser pen 100 includes a switching trigger device for electrically connecting the laser generating device with the first trigger circuit or the second trigger circuit. The switching trigger device can be in various forms, such as a key, a knob and the like, and can also be a touch switch, a light-sensitive switch and the like. The switching trigger device may be installed on the barrel 110, or may be installed in the installation cavity.
In some embodiments, to further improve the convenience of the operation of the switch trigger device, the operation of the switch trigger device is related to the pen tip 121, such as by the force of the pen tip 121, or by the device of the pen tip 121, and the like, which are described below by way of two examples.
On the one hand, the switching trigger device is electrically connected to the pen tip 121, and switches the first trigger circuit and the second trigger circuit according to the pressing force applied to the pen tip 121. In this embodiment, the laser pen 100 includes a first pressure sensor connected to the pen tip 121 for detecting a pressing force of the pen tip 121 along a length direction thereof; the switching trigger device is electrically connected with the pen point 121, connected with the first pressure sensor, and switches the first trigger circuit or the second trigger circuit according to the extrusion force applied to the pen point 121. The first pressure sensor may be disposed at an end of the pen tip 121, and in some embodiments, in order to avoid the first pressure sensor blocking the optical path or increasing difficulty of layout of the optical path due to the first pressure sensor, an abutting portion fixedly connected to the pen tip 121 may be disposed, and the first pressure sensor is disposed on the abutting portion. The abutting portion may be formed integrally with the pen tip 121 or may be a separate member. The first pressure sensor detects first extrusion force, the switching trigger device controls the first trigger circuit to be electrically connected with the laser generating device, the first pressure sensor detects second extrusion force, and the switching trigger device controls the second trigger circuit to be electrically connected with the laser generating device.
On the other hand, the switching trigger device is arranged on the pen point 121, the pen point 121 has an extension state and a contraction state, and the laser generating device is electrically connected with the first trigger circuit in the extension state; the laser generating device is electrically connected with the second trigger circuit in the contraction state. In this embodiment, the pen tip 121 can stretch and retract, and has at least two gears for extending and retracting, and of course, in some embodiments, three gears or even more gears can be provided as required. The switching trigger device is linked with the state of the pen tip 121, and takes a two-stage shift switch as an example. In the stretching state, a large part of the pen point 121 extends outside, and at the moment, the switching trigger device conducts the first trigger circuit with the laser generating device to realize the writing state of the pen point 121; in the retracted state, the pen tip 121 protrudes less outside (in some embodiments, the pen tip 121 may even be fully retracted inside the pen head 120), and at this time, the switching trigger device conducts the second trigger circuit with the laser generating device, so as to achieve the wiping state of the pen tip 121.
In some embodiments, in order to further improve the user experience of the laser pen 100, the laser pen 100 has a short-range interaction state and a long-range interaction state, the laser generating device is turned on when the pen tip 121 of the laser pen 100 is abutted and/or shielded in the short-range interaction state, the laser generating device is turned off when the pen tip 121 is not abutted or shielded, and the laser generating device is normally on in the long-range interaction state. In this embodiment, the laser pen 100 can write or erase on the light display screen in the short-range interaction state. In the remote interaction state, the laser emitted by the laser pen 100 may display a cursor or the like at a corresponding position on the light-sensing screen 200, and in some embodiments, the content of the position (or the peripheral area) where the laser is located may also be highlighted. In this manner, the laser pointer 100 not only allows a user to write and erase on the display screen, but also interacts with the light-sensing screen 200 at a location remote from the light-sensing screen 200. The switching between the short-range interaction state and the long-range interaction state may be realized by a key, a knob, a shift switch, or the like, and a specific example is described below.
The pen shaft 110 is provided with a short-range interactive key 150 and a long-range interactive key 130, and the long-range interactive key 130 and the short-range interactive key 150 are electrically connected with the laser generating device. When the short-range interaction key 150 is pressed, the laser pen 100 enters a short-range interaction state, and the laser pen 100 and the light-sensing screen 200 can perform short-range interaction, such as writing or wiping. When the remote interaction key 130 is pressed, the laser pen 100 enters a remote interaction state, and at this time, remote interaction between the laser pen 100 and the light-sensing screen 200 can be performed, and actions such as cursor indication can be performed.
In some embodiments, in order to further improve the user experience of the laser pen 100, the functions of pen-down writing or wiping and pen-up closing of the laser pen 100 are realized. There are various ways to implement the above functions, and two examples are described below.
As an example, whether the pen-down state (the pen tip 121 abuts against the optical sensor 200) or the pen-up state (the pen tip 121 leaves the optical sensor 200) is currently determined according to the pressure applied to the pen tip 121. The end part of the pen point 121 far away from the pen holder 110 is provided with a second pressure sensor, and the laser pen 100 further comprises a main control circuit; the main control circuit is electrically connected with the second pressure sensor and the laser generating device and is used for controlling the laser generating device to be turned on or turned off according to the detection data of the second pressure sensor. In the present embodiment, when the second pressure sensor detects that the axial pressing force of the pen tip 121 is greater than zero, it is considered that the pen tip 121 has already abutted against the light-sensing screen 200. When the second pressure sensor detects that the axial pressing force of the pen tip 121 is less than zero, it is considered that the pen tip 121 is not in abutment with the light-sensing screen 200.
It should be noted that the second pressure sensor in this embodiment and the first pressure sensor in the above embodiment may be two different independent sensors, or may be specific names of the same pressure sensor in different embodiments. When the first pressure sensor and the second pressure sensor are the same sensor, and the axial extrusion force applied to the pen point 121 is detected to be greater than zero, the current pen point 121 is considered to be abutted against the light sensing screen 200, and writing or wiping can be performed; when the axial extrusion force applied to the pen tip 121 is detected to be smaller than the second extrusion force, the pen tip is considered to be in the writing mode currently, and when the axial extrusion force applied to the pen tip 121 is detected to be greater than or equal to the second extrusion force, the pen tip is considered to be in the wiping mode currently. In combination with the above embodiments, the second pressing force is greater than the first pressing force, and the first pressing force may be any value greater than zero and less than the second pressing force.
In the second example, the end of the pen tip 121 far from the pen holder 110 is provided with an optical sensor, and the laser pen 100 further includes a main control circuit; the main control circuit is electrically connected with the optical sensor and the laser generating device and is used for controlling the laser generating device to be turned on or turned off according to detection data of the optical sensor. In this embodiment, the optical sensor is configured to detect a light sensing condition of the end portion of the pen tip 121 away from the pen holder 110, and when the optical sensor determines that the detected light intensity is greater than or equal to a preset light intensity, it indicates that the pen tip 121 is currently abutted to the light sensing screen 200 (a lower light source in a working state of the light sensing screen 200 on which relevant content is displayed, and at this time, the light intensity emitted by the light sensing screen 200 is greater than the light intensity of the current environment), and the laser generating device may be turned on; when the light sensor determines that the detected light intensity is less than the preset light intensity, it indicates that the pen tip 121 is currently separated from the light-sensing screen 200, and the laser generating device may be turned off.
