Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
Before introducing the technical solution of the present application, an interaction process between an active capacitive pen and a touch display in the prior art is described, as shown in fig. 1 and fig. 2, a touch electrode in the touch display 01 will emit a pulse signal on a display side, a sensing electrode in the active capacitive pen 02 will detect whether the pulse signal on the display side is received in real time, when the pulse signal on the display side is detected, it is described that the active capacitive pen 02 is close to the touch display 01, then a touch coordinate driving electrode in the active capacitive pen 02 emits the pulse signal, since the distance is close, the touch electrode in the touch display 01 can sense the pulse signal from the active capacitive pen 02 side, a pressure sensing sensor is disposed on a pen tip of the active capacitive pen 02, when the pen tip of the active capacitive pen 02 contacts the touch display 01, the pressure sensing sensor on the pen tip can sense pressure, the pressure induction sensor transmits a pressure induction signal to a Micro Control Unit (MCU) in the active capacitance pen 02, the MCU determines whether the pressure reaches a threshold value according to the pressure induction signal, if the pressure reaches the threshold value, the pen point is indicated to be in contact with the touch display 01, the MCU determines that the pressure reaches the threshold value and sends a pressure determination signal to the touch display 01 through Bluetooth, when the touch display 01 senses a pulse signal from the active capacitance pen 02 and receives the pressure determination signal from the active capacitance pen 02 through the Bluetooth, the active capacitance pen 02 can be determined to be in touch interaction with the touch display 01, a touch position is determined according to the pulse signal from the active capacitance pen 02 side, handwriting is displayed, and the water outlet action of the active capacitance pen 02 is completed. However, in the above process, the whole process period from the time when the pressure sensing sensor in the active capacitive pen 02 senses the pressure to the time when the touch display 01 displays the handwriting is long, which is about 120ms, wherein the MCU at the active capacitive pen 02 side is required to process, perform bluetooth communication, and respond to the touch display 01, which results in a long response time for the active capacitive pen to first discharge water when interacting with the touch display. The following describes examples of the present application.
As shown in fig. 3 and fig. 4, the present embodiment provides a control method of a touch display, which is used for interaction between a touch display 1 and an active capacitive pen 2, where the touch display 1 includes a pressure sensing module 11, the pressure sensing module 11 is used for sensing pressure on a surface of the touch display 1, and the specific structure and principle of the pressure sensing module 11 will be described later, the active capacitive pen 2 includes a touch coordinate driving electrode 21 located on a pen tip, the touch coordinate driving electrode 21 is used for transmitting a touch coordinate positioning signal so as to determine a touch position of the pen tip of the active capacitive pen 2 on the touch display 1 according to the touch coordinate positioning signal, the touch coordinate positioning signal is, for example, a pulse signal, the active capacitive pen 2 further includes a proximity sensing electrode 22 located on the pen tip, the proximity sensing electrode 22 is used for receiving a sensing signal from the touch display 1, in order to determine whether to approach the touch display 1, the touch display 1 further includes a capacitive touch electrode 12, the capacitive touch electrode 12 is used for transmitting a driving signal and receiving a sensing signal to implement a touch function, and if the sensing signal is a touch coordinate positioning signal from the active capacitive stylus 2, the active capacitive stylus 2 can be determined by using the signal, that is, the capacitive touch electrode 12 is used for sensing the touch coordinate positioning signal from the active capacitive stylus 2, and the control method of the touch display includes:
102, displaying the handwriting based on the touch coordinate positioning signal, that is, when the touch display 1 senses the touch coordinate positioning signal from the active capacitive pen 2 through the capacitive touch electrode 12 and meets a pressure condition, displaying the handwriting based on the touch coordinate positioning signal, wherein the meeting the pressure condition includes sensing a pressure above a preset pressure value through the pressure sensing module 11.
Specifically, the capacitive touch electrode 12 may emit a pulse signal (driving signal) and receive an induction signal, and when a finger or other device is disposed on the surface of the touch display 1, the induction signal received by the capacitive touch electrode 12 at the corresponding position is changed, so as to determine the touch position, thereby implementing the touch function. The capacitive touch electrode 12 includes a self-capacitive touch electrode and a mutual capacitive touch electrode. For example, for a self-contained touch electrode, the touch electrode includes a plurality of electrode blocks distributed in an array, each electrode block has an independent touch signal line, in the working process of the touch electrode, a pulse signal is provided to each touch electrode through the touch signal line, and a signal is received through the touch signal line, if no touch is made, the received signal is a determined signal, when a finger touch is made on a certain position on the surface of the touch display 1, the pulse signal on the corresponding touch electrode is changed due to the effect of capacitive coupling, so that the signal received through the touch signal line is changed, and the touch position can be determined based on the change; in addition, for example, the corresponding mutual capacitance type touch electrode includes a plurality of mutual capacitance type driving electrodes and a plurality of mutual capacitance type sensing electrodes, wherein the mutual capacitance type driving electrodes and the mutual capacitance type sensing electrodes are arranged in an insulated and crossed manner, in the working process of the touch electrode, pulse signals are sequentially provided for each mutual capacitance type driving electrode, signals are received through the mutual capacitance type sensing electrodes, if no touch is performed, the received signals are determined signals, when a certain position on the surface of the touch display 1 is touched by a finger, for example, the signals received by the sensing electrodes corresponding to the touch position can be changed due to the capacitive coupling effect, due to different time of the pulses on different mutual capacitance type driving electrodes, the mutual capacitance type driving electrode from which the sensing signal comes can be determined according to the time of the received signals, further the coordinate in one direction can be determined, and according to which mutual capacitance type sensing electrode the received signals belong to, the coordinates in the other direction can be determined, and the touch position can be determined by the coordinates in the two directions. As can be seen, for the capacitive touch electrode 12, on one hand, a pulse signal can be generated, and on the other hand, a sensing signal can be received. When a user controls the touch display 1 through the active capacitance pen 2, or when the user performs interaction between the active capacitance pen 2 and the touch display 1, the proximity sensing electrode 22 of the active capacitance pen 2 continuously senses a nearby signal, and the capacitive touch electrode 12 in the touch display 1 continuously transmits a pulse signal and receives the sensing signal, when the pen tip of the active capacitance pen 2 gradually approaches the touch display 1 and reaches a sufficiently close distance, the proximity sensing electrode 22 in the active capacitance pen 2 senses the pulse signal transmitted by the capacitive touch electrode 12 in the touch display 1, so as to determine that the active capacitance pen 2 has approached the touch display 1, and then the touch coordinate driving electrode 21 in the active capacitance pen 2 is controlled to transmit a touch coordinate positioning signal (pulse signal), at this time, because the distance between the pen tip of the active capacitance pen 2 and the touch display 1 is sufficiently close, therefore, the capacitive touch electrode 12 in the touch display 1 can sense the touch coordinate positioning signal emitted by the touch coordinate driving electrode 21 in the active capacitive pen 2, when the pen tip of the active capacitive pen 2 continuously approaches and contacts the surface of the touch display 1, pressure is applied to the surface of the touch display 1 through the pen tip, at this time, the pressure sensing module 11 in the touch display 1 can sense pressure, at this time, in step 101, if it is determined that the touch coordinate positioning signal from the active capacitive pen 2 is sensed through the capacitive touch electrode 12, and pressure reaching a pressure preset value is sensed through the pressure sensing module 11, it can be considered that the user is writing on the touch display 1 using the active capacitive pen 2, at this time, touch coordinates can be obtained according to the sensed touch coordinate positioning signal, and handwriting can be displayed based on the touch coordinates, even if the active capacitance pen 2 is out of the water.
According to the control method of the touch display in the embodiment of the application, the pressure sensing module arranged in the touch display is used for matching with the capacitive touch electrode to determine whether the pen point of the active capacitive pen is in contact with the surface of the touch display, and the condition is used as the condition for controlling the screen to display the handwriting when the active capacitive pen and the touch display are interacted.
In a possible embodiment, the satisfying the pressure condition further includes: the area where the pressure is higher than the preset pressure value includes a position located by the touch coordinate locating signal.
Specifically, the pressure sensing module 11 is further configured to determine a pressure position, for example, assuming that a position coordinate located by a touch coordinate locating signal sensed by the electrode 12 of the capacitive touch is (a1, a2), if a position range of the pressure sensed by the pressure sensing module 11, which reaches a pressure preset value or above, includes (a1, a2), it is considered that a pressure condition is satisfied, and if a position range of the pressure sensed by the pressure sensing module 11, which reaches a pressure preset value or above, is outside (a1, a2), it is considered that there is interference, and it is considered that the pressure condition is not satisfied, that is, it is considered that a pen point of the active capacitive pen 2 writes on the touch display 1, and therefore, handwriting is not displayed. Thus, it is possible to avoid the abnormal handwriting display caused by the interference, for example, when the user applies pressure on the touch display 1 by holding the hand of the active capacitive pen 2, if the pen tip of the active capacitive pen 2 is not yet in contact with the surface of the touch display 1, the capacitive touch electrode 12 in the touch display 1 may sense the touch coordinate positioning signal due to the close distance between the touch coordinate driving electrode 21 and the touch display 1, and at this time, the position located by the touch coordinate positioning signal is located outside the area of the pressure above the preset pressure value, and no handwriting should be displayed, and only when the pen tip of the active capacitive pen 2 is in contact with the touch display 1 and the applied pressure reaches above the preset pressure value, the area of the pressure above the preset pressure value includes the position located by the touch coordinate positioning signal, namely, the pressure condition is satisfied, so that the handwriting can be displayed more accurately.
In a possible embodiment, the satisfying the pressure condition further includes: the area of the pressure point area is smaller than the preset area, the pressure point area is an independent area in the area of the pressure above the preset pressure value, and the position located through the touch coordinate locating signal is located in the pressure point area.
Specifically, for example, as shown in fig. 5, it is assumed that an area a and an area B in the touch display are areas where a pressure above a preset pressure value is reached, that is, no other area except the area a and the area B reaches the pressure above the preset pressure value, where the area a is an independent area, the area B is an independent area, a position located by the touch coordinate locating signal is an O point, the O point is located in the area a, that is, the area a is a pressure point area, although the area B also reaches the pressure above the preset pressure value, the area B does not belong to the pressure point area because of belonging to an area separate from the area a, and in the step 101, it is further required to determine whether the area a is smaller than the preset area. Because the nib of the active capacitive pen 2 is thin, in order to further eliminate interference, the area of the pressure point region is used as a pressure condition, for example, a preset area is set in advance according to the size of the nib of the active capacitive pen 2, if the area of the pressure point region is smaller than the preset area, the pressure is considered to belong to normal writing performed by the nib of the active capacitive pen 2, and when all pressure conditions are met and a touch coordinate positioning signal from the active capacitive pen 2 is sensed by the capacitive touch electrode 12, handwriting can be triggered and displayed; and if the area of the pressure point area is larger than or equal to the preset area, the pressure is considered to belong to interference, and handwriting display is not triggered.
In one possible embodiment, satisfying the pressure condition further comprises: the edge of the pressure point area is circular.
Specifically, since the pen point of the active capacitive pen 2 is thin, when pressure is applied on the surface of the touch display 1 through the pen point of the active capacitive pen 2, the pressure value gradually decreases with a certain point as a center, and when the pressure point area is determined according to the pressure preset value, the obtained pressure point area is a circle, and then the pressure condition is considered to be satisfied, and if the pressure point area is not a circle, interference is indicated. The accuracy of handwriting display can be further improved by using whether the edge of the pressure point area is circular or not as a pressure condition.
In the present embodiment, the edge shape determination condition of the pressure point region is not limited, and for example, in other realizable embodiments, the edge shape of the pressure point region may not be used as the pressure condition, or, depending on the display region, another shape may be used as the edge shape determination condition of the pressure point region, and is not necessarily a standard circle.
In a possible implementation, in the step 102, during displaying the handwriting based on the touch coordinate positioning signal, the pressure sensing signal from the active capacitive pen 2 is received, and the handwriting is controlled based on the pressure sensing signal from the active capacitive pen 2.
