Detailed Description
In order to solve the above technical problem, an active pen for a touch display screen is provided in an embodiment of the present application, and specific implementations of the embodiment of the present application will be further described below with reference to the drawings of the embodiment of the present application.
An active pen is provided in an embodiment of the present application, and is used for performing touch control on a touch display screen, and referring to fig. 1A and fig. 1B, a schematic structural diagram of the active pen provided in the embodiment of the present application is provided; fig. 1A is a cross-sectional view of the active pen along a direction a-1, and fig. 1B is an external structural schematic diagram of the active pen.
The active pen comprises: the pen comprises a pen body, wherein a shell 10 of the pen body is provided with a sensing area 101; the pen point 13, the pen point electrode will output the drive signal, and the touch display screen is distributed with a certain number of detection electrodes in the horizontal direction and the vertical direction, so the drive signal output by the pen point electrode can be detected by the detection electrodes to obtain the detection signal, and the two-dimensional position coordinate of the pen point on the touch screen can be calculated according to the detection signal; the pressure touch detection module 2 is disposed inside the casing 10 and can be electrically connected to the control main board 12 of the active pen. The pressure touch detection module 2 can be used to detect a pressing operation and/or a touch operation applied by a user in the sensing region 101, and transmit the obtained pressure signal and/or touch signal to the control main board 12, so that the active pen can respond to the pressing operation or the touch operation of the user and execute a corresponding function. For example, a user presses the sensing region 101 a single time, and then performs an erase function; the user presses the sensing region 101 twice in succession, and then the selection function is executed; if the user presses the sensing region 101 for a long time, the drag function is performed, but the present application does not limit the operation of the user and the corresponding active pen function.
Specifically, referring to fig. 2, the pressure touch detection module 2 includes: the touch detection device includes a touch detection electrode 21, a first circuit board 22, a first pressure detection electrode 23, and a second pressure detection electrode 24. Among them, the touch detection electrode 21 is used to detect a touch operation applied by a user in the sensing region 101, i.e., to identify whether the user is operating in the sensing region 101. The first pressure detection electrode 23 and the second pressure detection electrode 24 are used to detect a pressing operation applied by the user within the sensing region 101, for example, a single pressing, two consecutive presses, or three consecutive presses.
The first surface of the touch detection electrode 21 is close to the inner surface of the sensing region 101, and the second surface of the touch detection electrode 21 is attached to the first surface of the first circuit board 22; a first surface of the first pressure detection electrode 23 is attached to a second surface of the first circuit board 22, and the second surface of the first pressure detection electrode 23 is opposite to the first surface of the second pressure detection electrode 24; a second surface of the second pressure detection electrode 24 faces an inner surface of the housing 10 opposite to the sensing region 101. The first pressure detection electrode 23 and the second pressure detection electrode 24 have a space therebetween and form a capacitance signal; the first pressure detection electrode 23 or the second pressure detection electrode 24 can be deformed based on a pressing operation applied by a user to change the distance therebetween so as to change the magnitude of the capacitance signal. When the pressure touch detection module 2 detects a touch operation applied by a user in the sensing region 101, the capacitance signal is used to determine a pressing operation applied by the user in the sensing region 101.
This application is through installing pressure touch-control detection module in the inside of initiative pen shell to replace installing in the multiple operation of the mechanical button discernment user on initiative pen shell surface, make initiative pen can carry out corresponding function, realized the expansion of initiative pen operation function. The initiative pen that this application embodiment provided adopts shell integral structure, need not to carry out the trompil to the shell promptly to dustproof, the waterproof performance of initiative pen has been improved, and has been avoided influencing the aesthetic property of initiative pen appearance design because of adopting the key cap of protrusion outside the initiative pen shell surface.
In addition, when a user holds the active pen to operate, under the condition that pressure is easily applied to a non-sensing area of a shell of the active pen, the pressure touch detection module senses the pressure due to deformation of the shell, and the active pen responds to the operation of the user wrongly.
The length direction of the pressure touch detection module in the embodiment of the application can be arranged along the length direction of the pen body, so that a user can more conveniently execute pressing operation or touch operation when holding the active pen. Preferably, the shape of the sensing region is consistent with the shape of the casing of the pen body (for example, when the pen body is a cylinder, the sensing region and the casing of the pen body have the same curvature radius), so that the shape of the pen body is flat and smooth, and the appearance attractiveness of the active pen is further improved. In addition, to facilitate the user to identify the sensing area, an identification pattern may be printed on the housing of the active pen, for example, with boxes or circles to identify the extent of the sensing area.
In a specific implementation of the embodiment of the present application, the touch detection electrode 21 includes at least two touch sub-electrodes; preferably, the at least two touch sub-electrodes are located on the same plane, and each touch sub-electrode has a certain interval therebetween, so that the touch detection electrode 21 can also detect a sliding operation applied by a user in the sensing region 101.
In one specific implementation of the present embodiment, as shown in fig. 3, the pressure touch detection module 2 is attached to the inner side of the casing 10 through the adhesive layer 25 and corresponds to the inner surface of the sensing region 101; the pressure touch detection module 2 further includes a supporting member 28, wherein the supporting member 28 is used for forming a gap between the first pressure detection electrode 23 and the second pressure detection electrode 24, and electrically connecting the first pressure detection electrode 23 and the second pressure detection electrode 24, so that the first pressure detection electrode 23 and the second pressure detection electrode 24 can simultaneously perform detection. There is an air gap 29 between the second surface of the first pressure-detecting electrode 23 and the first surface of the second pressure-detecting electrode 24, and since the support is non-deformable, a certain space is reserved for the deformation of the first pressure-detecting electrode 23 by providing the air gap 29. Therefore, when a user applies a pressing operation in the sensing region 101, the casing 10 of the pen body deforms and drives the first pressure detection electrode 23 to deform, the second pressure detection electrode 24 can deform differently from the first pressure detection electrode 23 under the action of the support 28, the distance between the first pressure detection electrode 23 and the second pressure detection electrode 24 is changed, and thus the size of the formed capacitance signal is changed.
The capacitance value between the first pressure-detecting electrode 23 and the second pressure-detecting electrode 24 is a relatively stable value without applying pressure by the user. When a user applies a pressure at the center position P of the sensing region 101, the housing 10 is slightly deformed in an arc shape and the deformation amount at the center position P (i.e., the stress point) is the largest, the deformation of the first pressure detection electrode 23 is mainly affected by the pressure at P, and the deformation of the second pressure detection electrode 24 is mainly affected by the supporting action of the support at a and the support at B, so that the deformation amount of the second pressure detection electrode 24 is smaller than that of the first pressure detection electrode 23, and the distance between the first pressure detection electrode 23 and the second pressure detection electrode 24 is changed. Since the two pressure-sensing electrodes form an approximate parallel plate capacitor, when the distance between the two pressure-sensing electrodes changes, the magnitude of the resulting capacitance signal changes accordingly.
In particular, the support 28 may be solder or conductive glue. The tin soldering scheme can be realized by adopting an SMT (surface mount technology) bonding process, and the conductive adhesive scheme can be realized by adopting a hot-pressing bonding process. The support 28 may be disposed at both ends to form an air gap 29 therebetween.
Forming the support member 28 with solder or conductive paste can provide better electrical conductivity and support between the first pressure-detecting electrode 23 and the second pressure-detecting electrode 24.
In a specific implementation of the embodiment of the present application, the supporting members 28 may be symmetrically disposed along the length direction of the pen body. Because when the user used the initiative pen, the direction of fingertip often was certain angle with the length direction of body of the pen, or the length direction of almost perpendicular to body of the pen to often press the central point that the sensing region was put when the user applyed the press operation, so with support piece along the length direction symmetry setting of body of the pen, be favorable to exerting the maximum deformation position that makes first pressure detection electrode and second pressure detection electrode when pressing the operation at the user and just correspond in the atress position, with the accuracy and the validity that improve pressure detection.
Preferably, the thickness of the adhesive layer 25 is greater than or equal to 0.1mm, so that the adhesive layer 25 can provide good adhesive force without affecting the accuracy of detection of the touch operation applied by the user by the touch detection electrode. Specifically, the adhesive layer 25 may be a double-sided adhesive tape to reduce the assembly difficulty and the assembly cost of the pressure touch detection module 2 in the housing 10, and facilitate the first pressure detection electrode 23 to deform correspondingly along with the deformation of the housing 10.
In an embodiment of the present invention, the first circuit board 22 can be a Flexible Printed Circuit (FPC), the first circuit board 22 is attached to the first stiffener 26 through the first adhesive layer 27, and the first stiffener 26 is attached to the inner side of the sensing region 101 through the adhesive layer 25.

Specifically, the first reinforcing plate 26 may be an FR4 reinforcing plate, and the first adhesive layer 27 may be an FR4 hot-press adhesive.
In an embodiment of the present invention, in the thickness direction of the pressure touch detection module 2, one end of the supporting member 28 contacts the second surface of the first circuit board 22, and the other end of the supporting member 28 contacts the first surface of the second pressure detection electrode 24. The second pressure detection electrode 24 can be made of a conductive plate such as a steel sheet or copper foil, and does not need to be attached to a printed circuit board, so that the thickness of the pressure touch detection module 2 is reduced, and the inner space of the active pen is saved.
