Abstract

A touch device includes the following elements. A touch panel has two panel analog circuits and a panel digital circuit. Two inverting modules are assembled to two neighboring sides of the touch panel respectively, electrically coupled to the two panel analog circuits, and each electrically coupled to the panel digital circuit. A controlling module is assembled to the touch panel. The two inverting modules process analog signals transmitted from the two analog circuits into digital signals that are transmitted to the controlling module through the panel digital circuit. Therefore, the touch device may decrease a layout width that is occupied by the panel analog circuit.

Description

technical field [0001] The invention relates to a touch device, and in particular to a touch device that can be used with a display of an electronic product as a control interface. Background technique [0002] In recent years, with the rapid development and wide application of information technology, wireless communication and information home appliances, the operation interface of many information products has changed from the traditional keyboard or mouse to the touch panel mounted on the display panel. Common types of touch panels include capacitive touch panels and resistive touch panels. These types of touch panels usually have analog circuits formed around them to transmit analog signals generated when the user triggers the electrode patterns. [0003] Taking the projected capacitive touch panel as an example, the projected capacitive touch panel uses two layers of stacked electrode patterns, and extends to the analog-to-digital converter (AD converter) through two a...
