One of the work (identifying the touch operation, obtaining the touch position information), or both work (identifying the touch operation, obtaining the touch position information). This embodiment can further improve the touch operation performance.

The touch system of the embodiment of the present invention includes a first touch module and a second touch module. The touch system of the embodiment of the present invention may be a dual touch system, such as the first touch mode in the embodiment of the present invention. The group is an electromagnetic touch module, and the second touch module is an infrared touch module. Of course, the second touch module can also be other types of touch modules, such as an optical touch module, a capacitive touch module, a piezoelectric touch module, and a surface acoustic wave touch module. In the embodiment, when the touch operation is performed by using the electromagnetic pen, the electromagnetic touch can have the advantages of high precision, fast reaction speed, and the original handwriting can be written, and at the same time, the electromagnetic operation can be avoided at the edge of the screen. The touch position information acquired by the touch module is abnormal (such as offset, loss, etc.), resulting in a series of problems in which the operation is not normal. In this embodiment, the second touch area is an area where the edge of the touch operation area is prone to abnormal writing of the electromagnetic pen.

In the embodiment of the present invention, the division of the first touch area and the second touch area may be determined according to actual conditions. If a touch form is prone to problems in some areas, the area may be drawn out in the area. The touch position information acquired by another touch form is used as the effective touch position information. Or, if a certain touch form has a large advantage in a certain area, the area can be drawn out, and the touch position information acquired by the touch form is used as effective touch position information in the area. A method for dividing the first touch area and the second touch area is given below. The division of the first touch area and the second touch area may be determined according to at least one of the following:

The first type is historical data of the touch operation positioning information. According to the historical data of the touch operation positioning information, the advantages and disadvantages of a certain touch form in different areas can be obtained, so that a better area (for example, can be used as the first touch area) and a worse area (for example, can be used as the second The touch area is obtained by using another touch form in its poor area by using the touch position information acquired in the better area. If the first touch module is an electromagnetic touch module and the second touch module is an infrared touch module, refer to FIG. 1 , the middle area is a better area of electromagnetic touch, and can be divided into the first touch area. The edge area is a poor area of electromagnetic touch and can be divided into a second touch area.

Second, writing habits. For example, according to writing habits, an area that is often written (for example, can be used as a first touch area) and an area that is not frequently written (for example, can be used as a second touch area), and in a frequently written area, for recognition speed and the like Touch position information obtained by recognizing a faster touch type can be used, and in an area that is not frequently written, since it is less used, a touch that is slower (which may have an advantage in price, etc.) can be used. Form obtained touch location information.

Third, touch module structure design and test data. The specific touch design of the touch module may result in a decrease in the touch operation performance of one touch form (for example, the first touch module) in one area, and another touch form (for example, the second touch). The touch operation performance of the control module has basically no effect. Therefore, based on the combined test data, a normal area (such as a first touch area) and an abnormal area (such as a second touch area) may be divided for the first touch module, and the first The touch area uses the touch position information acquired by the first touch module, and the second touch area uses the touch position information acquired by the second touch module. The first touch module is an electromagnetic touch module, and the second touch module is an infrared touch module (or one of the following: an optical touch module, a capacitive touch module, and a piezoelectric touch mode) For example, the group and the surface acoustic wave touch module are based on the structure design of the terminal including the touch module, and the electromagnetic touch has poor performance at the edge, and the edge of the touch operation area can be defined to be about 5-10 cm. The width range of the left and right (of course, may be adjusted according to the specific structure design) is an electromagnetic touch anomaly area, which is divided into a second touch area 1 whose area is the first touch area 2.

Of course, whether the first touch module and the second touch module simultaneously obtain the touch position information of the touch operation can be controlled by the control module (such as the touch module control module 33), and is performed in the first touch area. When the touch operation is recognized by the first touch module and recognized by the second touch module, the control module can enable the first touch module and the second touch module to simultaneously acquire the touch operation. The position information is controlled, but the control module obtains the touch position information obtained by the first touch module as the effective touch position information, and the corresponding operation is based on the effective touch position information.

Of course, whether the first touch module and the second touch module simultaneously obtain the touch position information of the touch operation may be controlled by the control module, and the touch operation in the first touch area may be the first touch When the module is recognized and recognized by the second touch module, the control module can enable the first touch module and the second touch module to simultaneously obtain the touch position information of the touch operation, but the control module is second. The touch position information acquired by the touch module is used as the effective touch position information, and the corresponding operation is based on the effective touch position information. Of course, the control module can obtain only the touch position information of the touch operation by the second touch module. At this time, there is only one touch position information. Therefore, the control module uses the touch position information acquired by the second touch module as the touch position information. Effective touch location information.

In this way, the touch positioning system of the embodiment of the invention is simpler and does not need to repeatedly enable or disable the touch module.

In the system embodiment of the present invention, when the control module determines the effective touch position information, since the ranges of the first touch area and the second touch area are known, the touch position information can be determined according to the obtained touch position information. The area where the operation is controlled (the first touch area or the second touch area) may be determined according to the above embodiment. It should be noted that the location of the touch operation may be based on the touch location information acquired by any touch module, and may be based on the touch location information acquired by a particular touch module according to actual conditions.
