Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
A first aspect of the present invention provides a touch device, please refer to fig. 1, which is a structural diagram of a touch device 100 according to an embodiment of the present invention, including: a pressure sensing assembly 1, a controller 2 and a light emitting assembly 3. The pressure sensing component 1 is used for detecting the pressing intensity of the touch device pressing on the touch display device and inputting the pressing intensity into the controller 2. The controller 2 is used for controlling the light emitting component 3 to emit a light signal according to the pressing intensity, wherein the signal parameter of the light signal corresponds to the pressing intensity.
The touch device 100 may be a stylus as shown in fig. 1, or may be a touch finger sleeve or a touch glove, and is not limited herein.
As shown in fig. 1, the pressure sensing assembly 1 may include a pressure contact 11 and a pressure sensor 12, wherein one end of the pressure contact 11 is exposed to the casing 9 of the touch device, and the other end of the pressure contact is connected to the pressure sensor 12 through a pressure conducting member 10, and the pressure conducting member 10 may be a spring or a resilient flexible member. When the pressure contact 11 presses the touch display device 100, the pressing strength is applied to the pressure sensor 12 through the pressure transmitter 10, so that the pressure sensor 12 senses the pressing strength. By providing the pressure sensor 12 in the touch device 100, the pressure contact 11 can protect the pressure sensor 12, thereby prolonging the service life of the touch device. Of course, in the implementation process, the pressure sensing assembly 1 is not limited to the above structure, and a pressure sensor may be directly arranged at the touch end of the pressure sensing assembly 1, and when the pressure sensor presses on the touch display device, the pressing strength is obtained, which is not limited herein.
In an alternative embodiment, an analog-to-digital converter may be further disposed between the pressure sensing assembly 1 and the controller 2, and since the intensity signal representing the pressing intensity obtained by the pressure sensing assembly 1 is often an analog signal, the intensity signal is converted into a digital signal by the analog-to-digital converter and then input to the controller 2 for processing. Furthermore, a front-end processing circuit can be arranged between the pressure sensing assembly 1 and the analog-to-digital converter, and the front-end processing circuit can comprise an amplifying circuit and a filtering circuit so as to amplify and filter the intensity signal output by the pressure sensing assembly 1 and then input the intensity signal into the analog-to-digital converter for digital-to-analog conversion, so that the intensity signal is more accurate.
Specifically, the front-end processing circuit and the analog-to-digital converter may be integrated on the same chip as the controller 2, or may be disposed on different chips, which is not limited herein.
In the embodiment of the present application, after the controller 2 obtains the intensity signal representing the pressing intensity, the intensity signal is analyzed to generate the control signal according to the magnitude of the pressing intensity represented by the intensity signal, so as to control the light emitting component 3 to emit the light signal. In an alternative embodiment, as shown in fig. 1, the light source driving component 4 may be connected between the light emitting component 3 and the controller 2, and the control signal sent by the controller 2 controls the light source driving component 4 to generate a current and/or a voltage matching the magnitude of the pressing intensity characterized by the light source driving component 4, so as to control the light emitting component 3 to emit the light signal corresponding to the signal parameter. Of course, the controller 2 may also directly output the corresponding current and/or voltage according to the pressing strength signal to control the light emitting component 3 to emit the light signal corresponding to the signal parameter, which is not limited herein.
In an alternative embodiment, for example, the light emitting assembly 3 may be configured to include a light source 31 and a light processing unit 32, and the controller 2 controls the light processing unit 32 to adjust the light signal emitted by the light source 31 so that the signal parameter of the light signal matches the pressing intensity. In this way, the signal parameters of the optical signal emitted by the light source 31 are adjusted by the light processing unit 32, so that the adjustment precision of the optical signal can be increased, the hardware requirement on the light source can be reduced, and the types of the adjustable signal parameters can be enriched. Of course, the light processing unit 32 may not be provided, and the controller 2 may directly control and adjust the signal parameter of the light signal emitted by the light source 31, which is not limited herein.
In an alternative embodiment, the signal parameter of the light signal emitted by the light emitting element 3 may be set to be positively correlated with the detected pressing intensity. The positive correlation can be that the signal parameter is set to be in direct proportion to the pressing intensity, or the signal parameter is set in a step from large to small according to the pressing intensity in a segmentation manner. Of course, the signal parameter may be set to be inversely related to the pressing strength, or the signal parameter may correspond to a preset mapping table of the pressing strength, which is not limited herein.
In an optional embodiment, the signal parameter corresponding to the pressing intensity may be a light intensity, a light wavelength, a light wave frequency, or a light beam size of the optical signal, so as to ensure accurate identification of the signal parameter by the touch display device, and of course, the signal parameter may also be a color of the optical signal, and the like, which is not limited herein.
In the implementation, the light emitting module 3 may have various structures and operation modes for different signal parameter settings, two examples are listed below:
first, the signal parameter is the light intensity of the optical signal.
The light emitting assembly 3 may be arranged to include a light source 31, and the controller 2 may control the current and/or voltage input to the light source 31 in accordance with an intensity signal indicative of the intensity of the depression, thereby controlling the light intensity of the light signal emitted by the light source 31. It is also possible to provide that the light emitting assembly 3 comprises a light source 31 and a light processing unit 32, wherein the light processing unit 32 is a filter switching device arranged on the light emitting path of the light source 31, and the controller 2 controls the light processing unit 32 to switch the filter according to the pressing intensity signal, so as to control the light intensity of the light signal emitted from the light source 31 to the touch device.
Specifically, the signal parameter is set to be the light intensity of the optical signal, so that the signal parameter can be accurately and efficiently detected by the built-in photosensitive component on the touch display device, the accuracy and the recognition efficiency of touch recognition are improved, and rich application scenes are provided. For example, in a setting scene, the corresponding screen brightness may be set according to the light intensity detected by the touch display device. In a game application scene, the corresponding game role moving distance can be displayed according to the light intensity detected by the touch display device.
Second, the signal parameter is the size of the optical signal.

As shown in fig. 2, which is a first structural diagram of the optical processing unit in the embodiment of the present invention, the optical processing unit 32 may be an aperture structure, and the controller 2 controls opening and closing of the aperture structure, so as to control a beam size of the optical signal. The dotted line diaphragm and the solid line diaphragm in fig. 2 are schematic images of the diaphragm structure in different opening and closing states under the control of the controller 2, the dotted line diaphragm corresponds to the dotted line light beam, and the solid line diaphragm corresponds to the solid line light beam.
As shown in fig. 3, which is a second structural diagram of the optical processing unit in the embodiment of the present invention, the optical processing unit 32 may be a focusing lens group, and the controller 2 controls the focusing lens group to adjust the focal length, thereby controlling the beam size of the optical signal.
Of course, the method for adjusting the beam size is not limited to the above two methods, and the beam size may be adjusted by using a structure such as a reflector, which will not be described herein.
Specifically, the signal parameter is set to the size of the optical signal, so that the built-in photosensitive element on the touch display device can accurately and efficiently detect the size of the light beam irradiated by the optical signal on the touch display device (the size of the light beam can be identified by detecting the size of the illumination area irradiated by the optical signal on the touch display device). Therefore, the accuracy and the recognition efficiency of touch recognition are improved, and richer application scenes can be provided based on the range size. For example, in an application scene such as writing or drawing, lines corresponding to thickness may be displayed according to the size of the illumination area detected by the touch display device. In a game application scene, the corresponding game character moving distance can be displayed according to the size of the illumination area detected by the touch display device.
Of course, the structure of the light emitting assembly 3 is not limited to the above two, and may be set according to the needs and application scenarios, and is not limited herein.
In an alternative embodiment, the touch device 100 may further include a power supply component 5 connected to the controller 2 and the light emitting component 3 for supplying power to the controller 2 and the light emitting component 3. Certainly, the touch device may not be provided with a power supply component inside, and the touch device is connected with an external power supply through a power supply interface to supply power, which is not limited herein.
