Embodiment 1
[0040] In order to express the scheme clearly, a few concepts are introduced first. The effective area, corresponding to the touch area, is mainly used to enable the touch structure to realize the touch function. It can also be said that the coil used to realize the touch function is mainly set in this area, and the effective area does not include special cases. Next, other auxiliary lines or control lines set in the peripheral area can also be used for touch control; the non-effective area corresponds to the peripheral area and surrounds the effective area, which can be used to set wiring, drive circuits and other components to Parts in the support valid area work correctly.
[0041] see Figure 1a and Figure 1b , it can be seen from the prior art that when the electromagnetic pen 112 touches the edge of the touch area 111, the generated touch signal is incomplete, and the signal is easily affected by noise, thereby reducing the linearity of the touch signal at the correspo...
Embodiment 2
[0052] Figure 5a It is a structural schematic diagram of a touch structure provided by Embodiment 2 of the present invention. see Figure 5a , on the basis of the touch structure described in Embodiment 1, the touch structure of this embodiment is: located at the edge of the effective area 211 and on the same side (on Figure 5a The first conductive pattern 211b is electrically connected to the corresponding side (on the left side) Figure 5a The traces 212 a in the non-active area in the center are electrically connected to form a coil 213 .
[0053] It should be noted, Figure 5a This is only a specific example of this embodiment, and in other specific examples, the first conductive pattern located on any other side may also be electrically connected. In addition, in the above situation, two or more first conductive patterns on the same side may also be electrically connected, and then electrically connected to the traces on the corresponding side to form coils on each ...
Embodiment 3
[0056] Figure 6a It is a structural schematic diagram of a touch structure provided in Embodiment 3 of the present invention. see Figure 6a , on the basis of the touch structure described in Embodiment 1, the touch structure of this embodiment is: located at the edge of the effective area 211 and on the adjacent two sides (on Figure 6a The first conductive pattern 211b is electrically connected to the left side and the upper side in the middle, and is connected with the corresponding side (in Figure 6a The traces 212 a in the non-active areas in the middle are electrically connected to form a coil 213 .
[0057] It should be noted, Figure 6a This is only a specific example of this embodiment, and in other specific examples, the first conductive pattern located on any other adjacent two sides may also be electrically connected. In addition, in addition to the above-mentioned group of first conductive patterns on any adjacent sides being electrically connected, the rema...
