detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a schematic flowchart of a touch method according to an embodiment of the present invention. The touch method is applied to a touch panel, where the touch panel is configured to receive an input signal, and the touch panel includes a first touch. The control area and the second touch area, as shown in FIG. 1, the method may include:

S101. Determine whether the first touch area and the second touch area receive an input signal.

Specifically, if the first object and the second object are on the first touch area, the first object sends a signal to the first touch area (ie, inputs a touch signal), and the second object The first touch area receives the auxiliary touch signal from the second object because the capacitance of the contact point is affected, and the input touch signal sent by the first object and the auxiliary touch signal generated by the second object are The input signal received for the touchpad. In one embodiment, the first object is a writing instrument, such as an active pen, and the active pen emits a current signal to the first touch area through the circuit included therein when the active pen is on the first touch area. The signal is the input touch signal received by the first touch area. Of course, the first object may also be a passive pen, that is, the function of actively transmitting a current signal to the touch panel is not provided, but the touch panel can pass Sensing the movement of the passive pen tip determines receipt of an input touch signal from the passive pen, the second object being a hand.

In order to more clearly distinguish the two different touch areas of the touch panel when the touch panel receives the input signal, an optional method is: the coordinates of two different areas of the touch panel can be performed. Marking separately, so that different regions of the touchpad are in different coordinate systems. Since the coordinates include the abscissa and the ordinate, at least one of the horizontal and vertical coordinates of the different regions of the touchpad is different.

In one embodiment, if both regions of the touch panel use x to represent the horizontal axis (abscissa), the vertical axis (ordinate) of one of the touch regions is identified by y, and the vertical of the other touch panel. The axis is denoted by y', therefore, the two regions of the touchpad are respectively in the xy coordinate system and the x-y' coordinate system; or, if both regions of the touchpad use y to represent the ordinate, then The abscissa of one touch area is represented by x, and the abscissa of the other touch panel is represented by x'. At this time, the two touch areas of the touch panel are respectively in the xy coordinate system and the x'-y coordinate system. Or, if the horizontal and vertical coordinates of one of the areas of the touchpad are represented by x and y, respectively, the horizontal and vertical coordinates of the other area are represented by x' and y', respectively. The touch areas are in the xy coordinate system and the x'-y' coordinate system, respectively.

In one embodiment, if the horizontal and vertical coordinates of one of the two touch regions of the touch panel are represented by x and y, respectively, the horizontal and vertical coordinates of the other region are represented by x' and y', respectively. The two touch areas of the touch panel are respectively in the xy coordinate system and the x'-y' coordinate system. If the input signal of the touch area where the xy coordinate system is located is received, the touch of the xy coordinate system is The area is the first touch area, and the area under the x'-y' coordinate system is the second touch area; or, if the input signal of the touch area where the x'-y' coordinate system is received is received, the x The touch area where the '-y' coordinate system is located is the first touch area, and the touch area where the xy coordinate system is located is the second touch area.

Optionally, if the two different touch areas of the touch panel are marked with the same mark, the two different touch areas of the touch panel can be distinguished by defining coordinate ranges of different touch areas. For example, if the horizontal and vertical coordinates of the two different touch areas of the touch panel are respectively represented by x and y, the range of the abscissa of one of the touch areas of the touch panel may be limited to a range of 0-6. If the range of the abscissa of the other touch area is limited to the range of 7-13, the touch area is distinguished by the limitation of the coordinate range.

It should be noted that the method for arranging the two different touch areas of the touch panel is exemplified and is not exhaustive. The manner of distinguishing is not limited in the present invention.

S102. When the first touch area receives the input signal, control the first touch area to generate input data according to the input signal, and control the second touch area to sleep.

Specifically, when the first touch area receives the input signal, that is, when the first touch area receives the input touch signal and the auxiliary touch signal, the first touch area can determine the first The object is in the input touch position of the first touch area, and at the same time, the auxiliary touch position of the second object in the first touch area is determined according to the auxiliary touch signal, indicating that the first touch area is at this time The working state, and the second touch area is in a dormant (idle) state, so that the second touch area can be controlled to enter sleep to save more energy.

In one embodiment, when the input object is in the input touch position of the first touch area according to the input touch signal, if the first object is an active pen, the input touch position is the The position of the pen tip of the active pen, so the area through which the input touch position passes is the area through which the pen tip of the active pen passes, so that generating input data according to the input touch position can be understood as generating corresponding according to the position of the pen tip of the active pen Character, text or graphics.

In an embodiment, when the input touch position determined by the input touch signal and the auxiliary touch position determined by the auxiliary touch signal change, the changed touch position and the auxiliary touch position may be determined according to the changed input touch position and the auxiliary touch position. Whether to change the working state of the first touch area and the second touch area.

In an embodiment, if the two different touch regions of the touch panel are identified by different coordinate systems, whether the switch is changed according to the coordinate change corresponding to the input touch position and the auxiliary touch position The working state of the touch area and the second touch area, and when the coordinates corresponding to the auxiliary touch position are used as the decision basis of the switching condition, the early triggering of the second touch area in the sleep state can be implemented. , can effectively avoid the loss of input data, and keep the user's writing fluency.

In this embodiment, by determining whether the first touch area and the second touch area receive an input signal, and when the first touch area receives the input signal, controlling the first touch area according to the first touch area The input signal generates input data, and controls the sleep of the second touch area. Since the input signal includes an input control signal of the first object and an auxiliary control signal of the second object, the touch panel can input the touch signal. Determining an input touch position where the first object is located, and determining an auxiliary touch position where the second object is located according to the auxiliary touch signal, so when the first touch area receives the input signal, indicating the first The object and the second object are both on the first touch area, and the first touch area is in an active state, and the second touch area is in an idle state, and the second touch area can be controlled to enter sleep to reduce The energy consumption of the touchpad achieves energy savings, which in turn makes the life of the portable touchpad longer.

FIG. 2 is a schematic flowchart of a touch method according to another embodiment of the present invention. As shown in FIG. 2, the method may include:

S201. Determine whether the first touch area and the second touch area receive an input signal.

Specifically, since the touch panel includes horizontal and vertical electrode cross-array, the lateral electrode forms a capacitance at an intersection by transmitting an excitation signal to the longitudinal electrode, and affects the horizontal of the touch point when the second object is at the intersection. The coupling of the vertical electrodes changes the capacitance between the intersections, so that the capacitance change caused by the second object at the intersection can be detected by the capacitance scan, so that the position of the capacitance change can be determined as the position of the second object Auxiliary touch position.

Wherein, when the two different touch areas of the touch panel are marked by using coordinates, the coordinate corresponding to the input touch position is a coordinate point, and the second object (hand) may cause one of the touch panels. The capacitance of the multiple positions may change at the same time. Therefore, the coordinate corresponding to the auxiliary touch position may be a coordinate point or a set of multiple coordinate points.

In one embodiment, when the user writes on the touchpad using the active pen, since the user's hand (ie, the second object) falls on the touchpad, the area determined by the capacitance scan is determined by the capacitance scan. There may be multiple positions of the capacitance change caused by the human hand, so the coordinate corresponding to the auxiliary touch position may be a set of multiple coordinate points; or the coordinate of the horizontal coordinate or the vertical coordinate of the set of the plurality of coordinate points may be the largest. The point is determined as the coordinate corresponding to the auxiliary touch position; or, the coordinate point with the abscissa or the ordinate in the set of the plurality of coordinate points may be determined as the coordinate corresponding to the auxiliary touch position; or, The coordinate point of the set of the plurality of coordinate points in which the abscissa or the ordinate is at the intermediate value is determined as the coordinate corresponding to the auxiliary touch position; in this embodiment, after the position of the capacitance change is determined by the capacitance scan, and according to the The way in which the position of the capacitance changes determines the number and the number of coordinate points is not limited.

S202, when the first touch area receives the input touch signal and the auxiliary touch signal, control the first touch area to generate input data according to the input touch signal, and control the second touch area to sleep. .

S203. When the touch area of the auxiliary touch signal received by the first touch area is less than a preset threshold, the second touch area is activated.

Specifically, if the set of the plurality of coordinate points caused by the second object is determined as the coordinate set corresponding to the auxiliary touch position in the coordinate system, the touch area of the second object may be determined by the coordinate set, and therefore, when When the touch area is smaller than the preset area threshold, the second touch area is activated.

Please refer to FIG. 3a , which is a schematic diagram of a first state of the touch panel provided by the embodiment. As shown in the figure, an input signal is received in the first touch area 302, and the active pen 301 is determined according to the input signal. The touch area of the first touch area 302 is determined. At the same time, the touch area of the user's hand 304 in the first touch area 302 can be determined by capacitive scanning. The first touch area 302 is working in this state. In the state, the second touch area 303 is in a sleep state. If the two different touch areas of the touch panel are respectively in the xy and x'-y' coordinate systems as shown in the figure, the coordinates corresponding to the input touch position are (3, 4), and the capacitance scan can be performed. Determining a set of coordinate points caused by the user's hand 304 to change the capacitance, so that the touch area of the user's hand 304 can be determined, and the touch area of the user's hand 304 is 5 cm ² when the user follows The movement of the hand 304 and the active pen 301 can generate characters according to the coordinates corresponding to the input touch position of the active pen 301, and when the user's hand 304 moves from the first touch area 302 to the second touch area 303, When the active pen 301 is still in the first touch area 302, it indicates that the user's hand 304 moves from the first touch area 302 to the second touch area 303 for writing, so that the user's hand 304 can be set to be detected. When the touch area of the touch area 302 is smaller than the preset area threshold (for example, 3 cm ² ), the second touch area is activated to receive the touch input signal, wherein the preset area threshold may be the touch The default preset value of the board can also be set by the user according to the needs. It is not limited in the embodiment of the present invention, but if the preset area threshold is larger, and most of the user's hand 304 is still in the first control area 302, the second touch area is activated to be accepted. The touch signal will generate more energy consumption than the touch panel with a smaller preset area threshold.

FIG. 3b is a second schematic diagram of the touch panel of FIG. 3a according to an embodiment of the present invention, when the user's hand 304 moves to the state as shown in FIG. 3b. At the intersection of the first touch area 302 and the second touch area 303, the coordinates corresponding to the input touch position in this state are (5, 4), and the coordinates corresponding to the input touch position are (5, 4) In the xy coordinate system, if the touch area of the user's hand 304 is 2 cm ² by the capacitance scan (and the preset area threshold is assumed to be 3 cm ² ), since the touch area of the user's hand 304 is smaller than The preset area threshold, since the active pen 301 is still in the first touch area 301, but the user's hand 302 has moved into the second touch area 303, in order to maintain the smoothness of the user's writing and maintain the stroke of the writing process If not lost, the second touch area 303 in the sleep state is triggered to enter the working state, and the working state of the first touch area 302 is maintained.

In one embodiment, if the input signal is not detected by the first touch area and the second touch area, the first touch area and the second touch area can be controlled to enter an active state. For example, FIG. 3c is a schematic diagram of a third state of the touch panel shown in FIG. 3a according to an embodiment of the present invention. When the user's hand 304 and the active pen 301 are separated from the first touch area 302 and the second touch, In the area 303, the input touch position of the active pen 301 and the auxiliary touch position of the user's hand 304 cannot be detected on the touch panel, so that the previous written content is not lost when the user restarts writing. To ensure the consistency of writing, the touchpad at this time is in working condition.

In an embodiment, when the input touch signal and the auxiliary touch signal are received in the second touch area, the active pen 301 and the user's hand 304 are moved from the first touch area to the first touch area. a second touch area, or the active hand 301 and the user's hand 304 start writing from the second control area, the second touch area is in an active state, and the first touch area is in an idle state, so the The first touch area sleeps to save more energy.

In one embodiment, if the state of the second touch area before the input touch signal and the auxiliary touch signal is in the sleep state, the active pen and the user's hand are illustrated. The first touch area is used, and with the movement of the active pen and the user's hand, the active pen and the user's hand are completely moved to the second touch area, then the active pen and the user's hand are at this time. The first touch area is not used. Therefore, in order to save energy, the first touch area can be adjusted from the original working state to the sleep state. For example, FIG. 3d is a fourth state diagram of the touch panel shown in FIG. 3a. It can be considered that the active pen 301 and the user's hand 304 move to the second touch area 303 at this time, and the first The touch area 302 is adjusted to a sleep state to save energy. The second touch area 303 is in an active state, and the second touch area 303 generates input data according to the input touch position of the received active pen 301.

Optionally, if the input touch signal of the first object is not received in the touchpad, but the auxiliary touch signal of the second object is received, it may be considered that the user does not raise the pen during the writing process of the user. The action of raising the hand may be considered as a pen preparation operation when the user is ready to write. At this time, the touch area receiving the auxiliary touch signal is in an active state, and the other touch area is in a sleep state.

For example, as shown in FIG. 4 is a fifth state diagram of the touch panel shown in FIG. 3a. At this time, a change in capacitance due to the user's hand 404 is detected in the touch area 402, so the The touch signal is received, but the touch signal from the active pen 401 is not received in the touch area 402. Therefore, the touch area 402 is in an active state and the touch area 403 is in a sleep state.

In the embodiment of the present invention, the touch panel determines whether the first touch area and the second touch area receive an input signal, and the input signal includes an input touch signal and an auxiliary touch signal, and is in the first The touch area receives the input touch signal, and when the second touch area receives the auxiliary touch signal, the first touch area is controlled to generate input data according to the input signal, and the second touch area is controlled to enter. In the sleep state, if the touch touch area of the auxiliary touch signal received by the first touch area is less than the preset area threshold, the second touch area is activated, or When the input signal is not detected by the first touch area and the second touch area, the first touch area and the second touch area are controlled to enter a working state, or when the first touch The area receives the input touch signal, and when the second touch area receives the auxiliary touch signal, the first touch area and the second touch area both enter a working state, or, when the second touch Control area When the input touch signal and the auxiliary touch signal are received, the first touch area is controlled to sleep, thereby realizing the energy saving of the touch panel and ensuring the smoothness of the user's writing, thereby improving the portable touch. The battery life of the control board.
