Embodiment Construction

[0024] A specific embodiment according to the present invention is a method for designing a sensing channel pattern, the flow chart of which is shown in figure 2 . The design method is applied to a touch panel including multiple electrodes and multiple sensing channels. The plurality of electrodes are connected to a plurality of sensors for matching the touch panel through the plurality of sensing channels. Firstly, step S22 is to establish a set of constraints using a minimum sensing channel width, a minimum sensing channel spacing, a maximum distribution width, and the respective lengths of the multi-segment sensing channels as parameters. Next, step S24 is to use a nonlinear programming program to determine the respective widths of the multiple sensing channels according to the set of constraints. The following instructions start with Figure 3A The electrode / sensing channel configuration presented is an example, detailing how to implement figure 2 Design flow 200 is ...

Abstract

The invention provides a sensing channel graphic design method applied to a touch panel with a plurality of electrodes and a plurality of sensing channels. The plurality of electrodes are connected to a plurality of sensors through the plurality of sensing channels, and the sensors are used for cooperating with the touch panel. The method includes: firstly, setting a group of constraint conditions by taking a minimum sensing channel width, a minimum sensing channel spacing, a maximum distribution width and respective lengths of the plurality of sensing channels as parameters; secondly, using a nonlinear programming program for determining respective widths of the plurality of sensing channels according to the group of constraint conditions.

Description

technical field [0001] The present invention is related to touch systems, and in particular to the pattern design of sensing channels used to connect sensors and electrodes in touch systems. Background technique [0002] With the advancement of technology, the operation interfaces of various electronic products have become more and more user-friendly in recent years. For example, through a touch screen, users can directly operate programs and input messages / texts / patterns on the screen with their fingers or a stylus, saving the trouble of using input devices such as keyboards or buttons. In fact, the touch screen usually consists of a sensing panel and a display disposed behind the sensing panel. The electronic device judges the meaning of the touch according to the position touched by the user on the sensing panel and the picture displayed on the display at that time, and executes the corresponding operation result. [0003] figure 1 It is an electrode / sensing channel co...
