Embodiment Construction

[0031] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] figure 1 It is a schematic diagram of the coil arrangement of the antenna board made by the ultrasonic buried wire method in the prior art.

[0033] The coils in the antenna board include coils arranged in the lateral direction (hereinafter referred to as the X direction) and coils arranged in the longitudinal direction (hereinafter referred to as the Y direction). figure 1 Shown are coils arranged in the X direction.

[0034] like figure 1 As shown, the coils 101 , 104 and 107 respectively have intersections with the coil 110 . In the prior art, the antenna board fabricated by the ultrasonic buried wire method often adopts the skipping method when encountering the intersections between the coils. This method reduces production efficiency and yield.

[0035] The study found, figure 1 The middle coils 101, 102, and 103 do not c...

Abstract

The invention discloses an antenna plate, a touchpad, an electronic device and a manufacturing method of the antenna plate for the touchpad, and belongs to the field of electromagnetic touch. The manufacturing method of the touchpad for the antenna plate comprises: a layered wire embedment step: producing a plurality of coils respectively in each of a plurality of sheets of base material in an ultrasonic wire embedding manner, so that each sheet of base material is formed into a coil layer, and multiple coils in each coil layer do not cross each other; and a lamination step: laminating the coil layers produced in the layered wire embedment step. According to the invention, excessive wire jumping in the ultrasonic wire embedment process is avoided, the velocity of wire embedment is increased, and thus the production efficiency is improved. Moreover, wire breaking due to excessive wire jumping is avoided, and thus the rate of finished products is increased. Thus, the invention can be widely applied in the field of electromagnetic touch.

Description

[0001] technical field [0002] The invention belongs to the technical field of electromagnetic touch control, and particularly relates to a manufacturing method of an antenna board for a touch panel, an antenna board for a touch panel, a touch panel and an electronic device. [0003] Background technique [0004] In today's widespread use of computers, equipment for human-computer interaction with computers has also been widely used. Among various human-computer interaction devices, touchpads are the most widely used. People use touchpads to realize handwriting input, computer screen control, etc. For example, touchpad technology is used on mobile phones with handwriting functions. Common touchpads include resistive, capacitive, infrared, electromagnetic, etc. They have their own characteristics and are suitable for products of different sizes in different fields. Among them, the electromagnetic induction type handwriting input touchpad (referred to as the electromagneti...
