Detailed Description
Before describing the present invention in detail with reference to the drawings and examples, it should be noted that the relative positional terms, such as "front", "rear", "left", "right", "upper" and "lower", used in the following description are based on the orientations shown in the respective drawings and the normal use orientations.
Before the present invention is described in detail, it should be noted that in the following description, like elements are denoted by the same reference numerals.
Referring to fig. 1, a first embodiment of a touch panel device 100 of the present invention is suitable for being mounted on an electronic device 4 having a display panel 41 and being operated by a stylus 5 or a finger (not shown).
Referring to fig. 2 to 4, the touch panel device 100 includes a touch substrate 1, a sensing unit 2, and a control unit 3. The sensing unit 2 is configured to detect whether the stylus 5 or the finger approaches the touch substrate 1, and the control unit 3 is in signal connection with the touch substrate 1, the sensing unit 2 and the electronic device 4 and is capable of controlling a cursor of the display panel 41 to move.
The touch panel device 100 can be changed among a scanning mode, a finger touch mode, a handwriting mode, a floating mode and an inking mode, and can output information with corresponding formats to the electronic devices 4 of different operating systems to the electronic devices 4.
When the touch panel device 100 is in the scanning mode, the sensing unit 2 continuously detects whether the stylus pen 5 or the finger is close to the touch substrate 1, and the control unit 3 does not output information to the electronic device 4.
When the sensing unit 2 detects that the finger approaches the touch substrate 1, the touch panel device 100 switches to the finger touch mode to operate the cursor movement on the display panel 41 on the touch substrate 1 by using the finger. The resolution of the output of the touchpad device 100 in the finger touch mode is typically low, with a typical resolution of 600 points per inch.
When the distance between the pen tip of the stylus 5 and the touch substrate 1 is smaller than a handwriting distance D1, the sensing unit 2 detects the stylus 5, the touch pad device 100 switches to the handwriting mode, the display panel 41 displays a handwriting area 42 with the same area and shape ratio as the touch substrate 1, and the control unit 3 shields the finger touch mode.
When the distance between the pen tip of the stylus 5 and the touch substrate 1 is smaller than a floating distance D2 and the stylus 5 is not in contact with the touch substrate 1, the sensing unit 2 detects the stylus 5, the touch panel device 100 is switched to the floating mode, and the control unit 3 shields the finger touch mode. In this embodiment, the floating distance D2 is greater than or equal to 0.5cm and less than or equal to 1.0cm, and the handwriting distance D1 is greater than or equal to the floating distance D2 and less than or equal to 5cm, but not limited thereto. Since the pen tip of the stylus 5 is close to the touch substrate 1 at this time, the control unit 3 can calculate the absolute coordinate position of the pen tip of the stylus 5 corresponding to the touch substrate 1.
When the pen tip of the stylus 5 contacts the touch substrate 1, the touch panel device 100 is switched to the ink-out mode, and the control unit 3 can calculate the absolute coordinate position of the pen tip of the stylus 5 on the touch substrate 1. In the ink-out mode, the contents displayed on the display panel 41 by the stylus 5 may be different according to the software or hardware of the application. If the handwriting pen is used in drawing software, lines can be displayed on the display panel 41, and if the handwriting pen 5 is used for handwriting input characters in iPad, the cursor can display handwriting in the handwriting area 42 when moving on the touch substrate 1.
Referring to fig. 3 and 5, the output process of the touch panel device 100 includes steps S1 to S15.
In step S1: the touch pad device 100 is in the scan mode.
In step S2: the control unit 3 determines whether the touch pad device 100 is in the handwriting mode, if yes, step S3 is executed, and if not, step S4 is executed.
In step S3: the control unit 3 shields the finger touch mode and displays the handwriting area 42 on the display panel 41.
In step S4: the control unit 3 determines whether the touch pad device 100 is in the floating mode, if yes, step S5 is executed, and if not, step S8 is executed.
In step S5: the control unit 3 shields the finger touch mode and determines whether the electronic device 4 is an iPad, if yes, step S6 is executed, and if no, step S7 is executed.
In step S6: the control unit 3 outputs Mouse movement (Mouse movement) information to the electronic device 4 in a human interface device (Human Interface Device, HID) protocol.
In step S7: the control unit 3 outputs information of the stylus 5 movements (Digitizer Pen Move) of the high resolution absolute coordinate displacement (High resolution absolute position move) to the electronic device 4 in a human interface device protocol.
In step S8: the control unit 3 determines whether the touch pad device 100 is in the ink output mode, if yes, step S9 is executed, and if not, step S12 is executed.
In step S9: the control unit 3 shields the finger touch mode and determines whether the electronic device 4 is an iPad, if yes, step S10 is executed, and if no, step S11 is executed.
In step S10: the control unit 3 outputs the information of pressing the left mouse button to the electronic device 4 according to the human interface device protocol.
In step S11: the control unit 3 outputs the information of the high resolution absolute coordinate displacement and the stylus 5 with the pen pressure (Digitizer with Pressure) to the electronic device 4 in a human interface device protocol.
In step S12: the control unit 3 determines whether the touch pad device 100 is in the finger touch mode, if yes, step S13 is executed, and if not, step S1 is executed.
In step S13: the control unit 3 determines whether the electronic device 4 is a Mac, iPad, or iPhone, if yes, step S14 is executed, and if no, step S15 is executed.
In step S14: the control unit 3 outputs information to the electronic device 4 in a format of Apple Magic Trackpad.
In step S15: the control unit 3 outputs information to the electronic device 4 in microsoft defined PTP protocol format (Windows Precision Touchpads).
Because the iPad does not support the absolute coordinate external device, in the steps S6 and S10, the mouse displacement is output by the humanized interface device protocol to satisfy the compatibility problem. In the present embodiment, when the electronic device 4 is a non-iPad, the electronic device 4 may be a PC, mac, or Chromebook or other device, and the high resolution means 4096 points per inch or more. In this embodiment, the sensing unit 2 is a plurality of capacitive sensing elements (not shown) for sensing an object approaching the touch substrate 1, and the control unit 3 is a computer or a calculator with a calculating function, but not limited thereto. In the embodiment, the stylus 5 is an Apple pen, but may be another kind of stylus, not limited thereto.
The following describes a process of performing absolute coordinate and relative coordinate conversion in this embodiment when the electronic device 4 is an iPad.
Referring to fig. 6 to 8, when a user wants to use the stylus 5 to write a letter "X" in the handwriting area 42, the user first brings the pen tip of the stylus 5 close to the touch substrate 1 to generate the handwriting area 42 on the display panel 41, and then the user can move the cursor into the handwriting area 42 by touching the display panel 41 or operating the touch substrate 1 with a finger.
Then, the stylus 5 is contacted with a starting contact point P0 at the upper left side of the touch substrate 1, so that the touch panel device 100 is switched to the inking mode, and the state that the stylus 5 presses the touch substrate 1 is kept to move towards a first contact point P1 at the lower right side of the touch substrate 1, and a first oblique line is drawn on the handwriting area 42.
At this time, the control unit 3 reports to the electronic device 4 that the cursor moves from the position corresponding to the initial contact point P0 in the handwriting area 42 to the position corresponding to the first contact point P1 in the handwriting area 42 and continuously presses the left mouse button during the movement.
Then, the stylus pen 5 is slightly away from the touch substrate 1, so that the touch panel device 100 is switched to the floating mode, and the stylus pen 5 is moved from above the first contact point P1 to above a second contact point P2 of the touch substrate 1 toward the upper right side of the touch substrate 1, and then the second contact point P2 is pressed down. At this time, the control unit 3 may calculate a movement vector of the first contact point P1 to the second contact point P2 according to the absolute coordinates of the first contact point P1 and the second contact point P2 on the touch substrate 1 and output the movement vector to the electronic device 4, so that the cursor moves along the movement vector in the handwriting area 42 by a distance corresponding to the distance between the first contact point P1 and the second contact point P2 without generating handwriting.
It should be noted that, due to the performance difference between the sensing unit 2 and the control unit 3, the stability of the signal received by the sensing unit 2 when detecting the floating movement of the stylus 5 may be poor, so that a larger jitter trace may be formed when the handwriting generated by the floating movement of the stylus 5 is displayed on the handwriting area 42, so in this embodiment, the touch pad device 100 does not output information to the electronic device 4 when the stylus 5 is in the floating mode and the control unit 3 is in the floating movement.
At this time, the control unit 3 reports to the electronic device 4 that the cursor moves from the position corresponding to the first contact point P1 in the handwriting area 42 to the position corresponding to the second contact point P2 in the handwriting area 42 and the left mouse button is not pressed during the movement. Since outputting the mouse movement with the human interface device protocol limits the displacement of the single movement, if the distance between the first contact point P1 and the second contact point P2 is longer, the control unit 3 splits the distance of the floating movement of the stylus 5 into multiple segments and transmits the segments to the electronic device 4.
Then, the stylus 5 is contacted with the second contact point P2, and the state of pressing the touch substrate 1 is kept to move towards an end contact point P3 at the lower left of the touch substrate 1, and a second oblique line intersecting the first oblique line is drawn, so that writing of the character "X" is completed.
At this time, the control unit 3 reports to the electronic device 4 that the cursor moves from the position corresponding to the second contact point P2 in the handwriting area 42 to the position corresponding to the ending contact point P3 in the handwriting area 42 and continuously presses the left mouse button during the movement process.
In this way, the absolute coordinates of the stylus 5 detected by the touch substrate 1 when in contact are converted into relative coordinates acceptable to the electronic device 4 during writing, so as to solve the problem that the stylus 5 cannot be blindly written and displayed on the display panel 41 by the touch pad device 100 when the electronic device 4 is an iPad.
Referring to fig. 9, a second embodiment of the touch panel device 100 of the present invention is similar to the first embodiment, except that the touch panel device 100 is externally connected to the electronic device 4 for use.
Referring to fig. 10, a third embodiment of a touch panel device 100 according to the present invention is similar to the first embodiment, except that the touch panel device 100 is an external drawing board wirelessly connected to the electronic device 4, and the area shape of the touch substrate 1 is the same as the area and shape ratio of the display panel 41.
In the third embodiment, the implementation of writing or drawing by the stylus 5 is slightly different from that of the first embodiment, and when the stylus 5 is far away from the touch substrate 1 and the touch pad device 100 is beyond a predetermined time after switching from the handwriting mode to the scanning mode, the control unit 3 controls the cursor to move to an initial position B0 in the upper left corner of the display panel 41. When the stylus 5 continues to contact a predetermined contact point AP of the touch substrate 1, the control unit 3 may calculate an displacement vector from the initial point A0 to the predetermined contact point AP by using absolute coordinates of the initial point A0 and the predetermined contact point AP on the touch substrate 1, and output the displacement vector to the electronic device 4, so that the cursor moves from the initial position B0 to a position corresponding to the predetermined contact point AP in the handwriting area 42 according to the displacement vector. And the manner of writing or drawing when the cursor is moved is the same as that of the first embodiment.
In this embodiment, the predetermined time is 2 to 5 seconds, and is generally adjusted according to the performance of the electronic device 4 and the distance of the touch substrate 1 from the stylus 5, and is set longer when the handwriting distance D1 is shorter and is set shorter when the handwriting distance D1 is longer.
In other variations of the present embodiment, when the predetermined time is exceeded after the touch pad device 100 is switched from the handwriting mode to the scanning mode, the cursor may also be moved to the position of the lower left corner, the upper right corner or the lower right corner of the display panel 41 to achieve the function of initializing or zeroing the position of the cursor.
In summary, in the touch pad device 100 of the present invention, the absolute coordinates of the contact point of the stylus 5 with the touch substrate 1 can be converted into the relative coordinates that can be used by the iPad, so that the function of writing or drawing on the iPad through the touch substrate 1 is achieved, and the control unit 3 can output the corresponding information format for the tablet computer or the notebook computer of different operating systems, so that the touch pad device 100 can be applied to different electronic devices 4, and the purpose of the present invention can be achieved.
The foregoing is merely illustrative of the present invention and, as such, is not intended to limit the scope of the invention, but rather is intended to cover all modifications and variations within the scope of the present invention as defined by the appended claims and their equivalents.
