Problems solved by technology

However, such a design requires twice as many conductive thin film structures, requiring higher cost
[0003] It can be seen that the above-mentioned existing touch device and method that ignores palm touch pressure obviously still have inconvenience and defects in product structure, method and use, and need to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve

Abstract

The present invention relates to a method and device for palm rejection. The present invention carries out palm rejection on a multi-touch panel. The panel is first touched by a palm before the detection of a finger or pen to define a rejection region and the touch location of the finger or pen is detected outside that rejection region. The present invention, when the rejection region and the touch location of the finger or pen have been detected, is able to continuously detecting a region touched by the palm using a detected range defined by the rejection region.

Description

technical field [0001] The present invention relates to a multi-point touch device and method, in particular to a multi-point touch device and method that ignores palm touch pressure. Background technique [0002] U.S. Patent No. US6628269 discloses a touch device that ignores the touch pressure of the palm. Compared with the traditional resistive touch device that uses a set of two-layer conductive films facing each other, this patent uses two sets of two-layer conductive films facing each other stacked up and down. film. A looser insulating spacer is used between the upper face-to-face conductive films, and a tighter insulating spacer is used between the lower face-to-face conductive films. Therefore, only the tip contact pressure can cause the two face-to-face conductive films below to contact, and the larger area The contact pressure (such as palm contact pressure) can only cause the two layers of conductive films on the upper surface to contact, so the contact pressure...
