Detailed Description
In the embodiments of the present disclosure, numerous specific details are provided to provide a thorough understanding of particular embodiments of the invention; one skilled in the art will recognize, however, that the invention may be practiced without one or more of the specific details; in other instances, well-known details are not shown or described to avoid obscuring aspects of the invention. The technical content and the detailed description of the present invention are described below with reference to the accompanying drawings:
please refer to fig. 1, which is a schematic diagram of a pressure output signal transmission of an active capacitive stylus device according to a first embodiment of the present invention; please refer to fig. 2, which is a schematic diagram of transmitting a constant pressure output signal according to a first embodiment of the active capacitive stylus apparatus of the present invention. The active capacitive stylus device 10 of the present invention is applied to a touch screen device 20 for drawing or writing on the touch screen device 20; the active capacitive stylus device 10 includes a stylus pen core 102, a pressure sensor 104, a stylus signal microcontroller 106, a pressure output signal locking unit 108, and a stylus housing 118; the components of the active capacitive stylus device 10 are connected to each other, and the pressure sensor 104 and the stylus signal microcontroller 106 are disposed within the stylus housing 118; in the embodiment shown in fig. 1 and 2, the pressure output signal locking unit 108 is a button structure disposed on the stylus housing 118, but the present invention is not limited thereto.
When the active capacitive stylus device 10 is drawing or writing on the touch screen device 20, the pressure sensor 104 senses a pressure 110 from the stylus pen core 102 to generate a pressure input signal 112; after the pressure sensor 104 generates the pressure input signal 112, the pressure sensor 104 transmits the pressure input signal 112 to the stylus signal microcontroller 106; after the stylus signal microcontroller 106 receives the pressure input signal 112, the stylus signal microcontroller 106 converts the pressure input signal 112 to obtain a pressure output signal 114.
After the stylus signal microcontroller 106 obtains the pressure output signal 114, the stylus signal microcontroller 106 detects the state of the pressure output signal lock unit 108, which can be described as the following 3 points:
1. if the button structure is in a bounce-off state (as shown in FIG. 1), the stylus signal microcontroller 106 detects that the pressure output signal locking unit 108 of the button structure is in a disabled state, and then the stylus signal microcontroller 106 transmits the pressure output signal 114 to the stylus pen core 102. That is, if the pressure 110 is greater, the pressure output signal 114 is greater; if the pressure 110 is smaller, the pressure output signal 114 is smaller.
2. If the button structure is in a depressed inactive state (as shown in FIG. 2), the stylus signal microcontroller 106 detects that the pressure output signal lock 108 of the button structure is in an enabled state, and then the stylus signal microcontroller 106 sends a constant pressure output signal 116 (described at point 3 below) to the stylus pen core 102. That is, regardless of the magnitude of the pressure 110, the stylus signal microcontroller 106 sends the constant pressure output signal 116 to the stylus pen core 102.
3. If the key structure is switched from the bounce-off state to the press-off state, the touch-control pen signal microcontroller 106 detects that the pressure output signal lock unit 108 of the key structure is switched from the disable state to the enable state, and then the touch-control pen signal microcontroller 106 defines the pressure output signal 114 as the constant pressure output signal 116. That is, when the user uses the active capacitive stylus device 10 to draw or write on the touch screen device 20, if the user wants to fix the thickness of the subsequent line as the thickness of the current line, the user can press the key structure; for the stylus signal microcontroller 106, the stylus signal microcontroller 106 detects that the key structure is switched from the disabled state (the bounce-off state) to the enabled state (the press-off state), so that the stylus signal microcontroller 106 defines the pressure output signal 114 as the constant pressure output signal 116 at this time.
The utility model discloses a use situation does: at the beginning, the key structure is in the bounce stop state, if the pressure 110 is greater, the pressure output signal 114 is larger, the line displayed on the touch screen device 20 is thicker, and if the pressure 110 is smaller, the pressure output signal 114 is smaller, the line displayed on the touch screen device 20 is thinner. Then, if the user presses the button structure, the instantaneous pressure output signal 114 is defined as the constant pressure output signal 116, and then as long as the button structure is still in the press-stop state, regardless of the magnitude of the pressure 110 being written, the stylus signal microcontroller 106 transmits the constant pressure output signal 116 to the stylus pen core 102 to maintain the thickness of the line displayed on the touch screen device 20 as the thickness of the line when the user momentarily presses the button structure.
Furthermore, in one embodiment of the present invention, if the stylus signal microcontroller 106 detects that the pressure output signal lock unit 108 is in the enabled state, and if the pressure 110 is not zero (i.e., the active capacitive stylus device 10 is in contact with the touch screen device 20 for drawing or writing), the stylus signal microcontroller 106 transmits the constant pressure output signal 116 to the stylus pen core 102. In other words, if the stylus signal microcontroller 106 detects that the pressure output signal lock unit 108 is in the enabled state, but if the pressure 110 is zero (i.e., the active capacitive stylus device 10 is not touching the touch screen device 20), the stylus signal microcontroller 106 does not send the constant pressure output signal 116 to the stylus pen core 102, thereby saving power.
Please refer to fig. 3, which is a schematic diagram of a second embodiment of an active capacitive stylus apparatus according to the present invention; the components shown in fig. 3 are the same as those shown in fig. 1 and 2, and their description will not be repeated here for the sake of brevity. The active capacitive stylus device 10 further includes a clear function button 120, the clear function button 120 is connected to the stylus signal microcontroller 106, and the clear function button 120 is disposed on the stylus housing 118.
If the stylus signal microcontroller 106 detects that the clear function button 120 is pressed, the stylus signal microcontroller 106 stops sending the pressure output signal 114 or the constant pressure output signal 116 to the stylus pen core 102 regardless of whether the pressure output signal lock unit 108 is in the disabled state or the enabled state, but the stylus signal microcontroller 106 sends a clear signal 122 to the stylus pen core 102 to clear the lines displayed on the touch screen device 20.
Please refer to fig. 4, which is a schematic diagram of a third embodiment of an active capacitive stylus apparatus according to the present invention; the components shown in fig. 4 are the same as those shown in fig. 1 and 2, and their description will not be repeated here for the sake of brevity. The active capacitive stylus device 10 further includes a menu trigger 124, the menu trigger 124 is connected to the stylus signal microcontroller 106, and the menu trigger 124 is disposed on the stylus housing 118.
If the stylus signal microcontroller 106 detects that the menu trigger switch 124 is pressed once (similar to a right mouse button being pressed once), the stylus signal microcontroller 106 stops sending the pressure output signal 114 or the constant pressure output signal 116 to the stylus pen core 102 regardless of whether the pressure output signal locking unit 108 is in the disabled state or the enabled state, but the stylus signal microcontroller 106 sends a menu signal 126 to the stylus pen core 102 to display a menu on the touch screen device 20.
Please refer to fig. 5, which is a schematic diagram of a fourth embodiment of an active capacitive stylus apparatus according to the present invention; the components shown in fig. 5 are the same as those shown in fig. 1 and 2, and their description will not be repeated here for the sake of brevity. The pressure output signal locking unit 108 is a wireless signal receiver; the pressure output signal locking unit 108 of the wireless signal receiver receives a wireless control signal 32 wirelessly transmitted by a wireless controller 30 to determine whether the pressure output signal locking unit 108 is in the enabled state, the disabled state or switched from the disabled state to the enabled state.
The utility model discloses an efficiency lies in making the thickness of the lines that the touch-control pen was drawn on touch-control screen be even, no matter the user uses the strength size of touch-control pen.
