Problems solved by technology

However, the current customary capacitive touch panel only responds to conductive touch objects, such as using fingers or special conductive pens to achieve touch. For non-conductive touch objects or when people wear thick gloves, it is often In addition, it is precisely because of the sensitivity of the capacitive touch panel to conductive objects that the capacitive touch panel is prone to misoperation in a water environment, let alone work in water

Abstract

The invention provides a capacitance type touch panel. The capacitance type touch panel mainly comprises a touch circuit, a touch sensing electrode substrate and a touch public electrode substrate; several touch sensing electrode units are arranged on the touch sensing electrode substrate; an outgoing electrode of every touch sensing electrode is connected with the touch circuit, and a touch public electrode is arranged on the touch public electrode substrate; two substrates are insulated and isolated by compressive deformable partitioning matters; the touch sensing electrode and the touch public electrode are still in an insulation and isolation state when the compressive deformable partitioning matters are under the compression state. According to the capacitance type touch panel, the capacitance type touch panel is operated by a non-conductive touch matter, and a complete waterproof capacitance touch scheme is realized.

Description

technical field [0001] The invention relates to a capacitive touch panel, in particular to a pen-writable capacitive touch panel. Background technique [0002] Touch is the most important way of human perception and the most natural way for people to interact with machines. Touch panels have been widely used in many fields such as personal computers, smart phones, public information, smart home appliances, and industrial control. In the current touch field, there are mainly resistive touch panels, photoelectric touch panels, and ultrasonic touch panels. In recent years, capacitive touch panels have developed rapidly. [0003] Resistive touch panels are still the leading product in the market, but the double-layer substrate structure of the resistive touch panel makes the reflection of the touch panel greatly affect the brightness of the display when the touch panel and the display panel are stacked together. , contrast, color saturation and other display quality will great...
