Problems solved by technology

[0005] In addition to the insufficient positioning accuracy of the existing signal sheet, there are also many pads on the back of the signal sheet. There are 5 pads on the back of the signal sheet with the structure shown in Figure 1, and the middle one is used for the connection between the positive electrode 101 and the signal line. , around 4 for the connection of the negative pole 102 and the ground wire

Embodiment Construction

[0037] The specific structure of an embodiment of the signal sheet of the present invention is as follows Figure 2A shown. The positive electrode 201 of the signal sheet is a plate-shaped body, and the positive electrode 201 has a first lateral width L1. An insulating layer 203 protrudes from one side edge of the positive electrode 201, and the insulating layer 203 has a second width L2. by Figure 2A According to the direction in , one longitudinal side of the insulating layer 203 is connected to the edge of the positive electrode 201 , and the other side is connected to the negative electrode 202 , and the third width of the negative electrode 202 is L3. The width L1 of the positive electrode 201 is much larger than the width L2 of the insulating layer, and the width L2 of the insulating layer is close to or substantially equal to the width L3 of the negative electrode. The width L3:L1 is preferably 1:10 to 1:2.

[0038] according to Figure 2A In the first embodiment ...

Abstract

The invention discloses a signal chip and a touch input device with a built-in signal chip. The signal chip (2) comprises sheet anodes (201 and 201'), insulating layers (203 and 203') and cathodes (202 and 202'), wherein the anodes have first width (L1) in horizontal direction; one longitudinal side edges of the anodes (201 and 201') are raised to form the insulating layers (203 and 203') which have second width (L2); one longitudinal sides of the insulating layers (203 and 203') are connected with edges of the anodes (201 and 201') and the other sides of the insulating layers (203 and 203') are connected with the cathodes (202 and 202') which have third width (L3); and the first width of the anodes (201 and 201') is more than the second width of the insulating layers (203 and 203') and the third width of the cathodes (202 and 202'). Thus, the area of the signal chip is reduced, the positioning dead zones are decreased, and the touch accuracy is improved.

Description

technical field [0001] The present invention relates to a touch input device, in particular to a signal sheet for a touch input device and a touch input device with the signal sheet built in. Background technique [0002] With the rapid development of electronic information equipment, people's input interaction with electronic information equipment is no longer limited to button operations, and more and more requires direct click on the panel for interaction. At present, in order to be able to realize the coordinate input of touch points such as hands and pens, the existing technology mainly sets a signal touch device on the contact surface of the panel (the side directly contacted by fingers, pens, etc.), so as to realize the touch control on the panel. direct human-computer interaction. [0003] The existing signal chips are divided into diameters, such as 4mm, 6mm, 9mm and so on. A specific structure of an existing signal slice is shown in FIG. 1 . The signal sheet inc...
