Embodiment 1
[0028] Embodiment 1 of the present invention discloses a method for locating a touch point, such as figure 1 shown, including:
[0029] Step S101 , detecting the current value of each marker quantity of each partition, and acquiring the standard value of each marker quantity and a preset threshold value.
[0030] In step S101, the area to be scanned is divided into several partitions, and the area and shape of each partition can be the same or different. For example, in the area where the touch occurs more densely, the area is divided into smaller partitions, and the number of partitions is increased, thereby improving The accuracy of locating touch points; in the area where the touch occurs relatively sparsely, the number of partitions with a small number of large areas is divided, the number of partitions is reduced, and the power consumption of locating touch points is reduced.
[0031] In step S102 , according to the current value of each marker quantity, the standard val...
Embodiment 2
[0042] Embodiment 2 of the present invention discloses a method for locating a touch point, such as Figure 4 shown, including the following steps:
[0043] Step S201, detecting the current value of each flag quantity of each partition, and obtaining the standard value of each flag quantity and a preset threshold;
[0044] Step S202, according to the current value of each marker, the standard value of the marker and the preset threshold, determine the touch occurrence zone;
[0045] Step S203 , scanning the touch-occurring partition, locating at least one touch point, scanning the touch-occurring partition at least one adjacent partition to the touch-occurring partition, and locating the touch point.
[0046] Through the method for locating a touch point disclosed in Embodiment 2 of the present invention, at least one subregion adjacent to the subregion where the touch point occurs is scanned to expand the scanning range, thereby improving the accuracy of locating the touch p...
Embodiment 3
[0048] In the process of locating the touch point in the prior art, the driving line and the scanning line are always in the working state, and interfere with each other during the locating process of the touch point, resulting in great noise. Embodiment 3 of the present invention discloses a method for locating touch points on the basis of Embodiment 1, such as Figure 5 as shown,
[0049] Step S301, detecting the current value of each flag quantity of each partition, and obtaining the standard value of each flag quantity and a preset threshold;
[0050] Step S302, according to the current value of each marker quantity, the standard value of the marker quantity and the preset threshold value, determine the touch occurrence zone;
[0051] Step S303, stop scanning the non-touch occurrence zone.
[0052] Step S304, scanning the touch occurrence area to locate at least one touch point.
[0053] Through a method for locating touch points disclosed in Embodiment 3 of the present...
