Manufacturing method of projected capacitive touch whiteboard and projected capacitive touch whiteboard

Abstract

The invention discloses a method for manufacturing a projected capacitive touch whiteboard and the projected capacitive touch whiteboard. The manufacturing method includes: S1, making a main board and a projected capacitive screen; S2, wiring the edge of the projected capacitive screen Connect with the capacitive touch integrated circuit chip on the main board; S3, install the main board into the casing, install the projected capacitive screen on the front end of the case, and make the projected capacitive touch whiteboard. In the method for manufacturing a projected capacitive touch whiteboard of the present invention, the electrodes of the capacitive screen are made by setting a metal layer on the substrate to make a multi-touch projected capacitive screen; the touch whiteboard manufactured by the capacitive screen can be Use with a projector to achieve multi-touch, reduce misoperation, and do not need a special pen, touch operation can be realized by finger touch.

Description

technical field [0001] The invention relates to the field of capacitive touch technology, in particular to a method for manufacturing a projected capacitive touch whiteboard and the projected capacitive touch whiteboard. Background technique [0002] With the continuous development of electronic technology, electronic whiteboards have appeared, which can be used with computers and projectors, and can realize paperless office and teaching. It has the characteristics of dust-free writing, free writing, and remote communication. Existing electronic whiteboards include infrared electronic whiteboards and electromagnetic electronic whiteboards; among them, infrared electronic whiteboards mainly rely on the infrared tubes around the board for induction operations, without special pens, and can directly enter the board surface with fingers or other objects The touch operation can be realized in the sensing area; the electromagnetic electronic whiteboard mainly relies on the coopera...

Problems solved by technology

[0003] Among the above two existing electronic whiteboards, the electromagnetic electronic whiteboard needs to use an electromagnetic pen to realize touch operation, which is inconvenient to use; while the infrared electronic whiteboard does not need a special pen and has no pressure sensing, as long as a finger or object enters the sensing area , it can be recognized as a touch operation, which is prone to misoperation and is easily disturbed by the external environment such as strong light, dust coverage, etc., so the operation is not sensitive or misoperation
