Embodiment Construction

[0027] The capacitive touch sensing device of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, a capacitive touch sensing device includes a base 1, a transparent panel 8, a circuit board 3, an indicating light source 4, a transparent conductive layer, and a conductor 5.

[0029] The base 1 has a double-layer structure, including a top plate and a bottom plate. Between the top plate and the bottom plate is a cavity for placing the circuit board 3. A sealant layer 9 is smeared between the light-transmitting panel 8 and the top, so that the inner cavity of the base is in a relatively sealed environment to prevent contamination by the external environment.

[0030] An indicating light source 4 is installed on the circuit board 3, a light-transmitting hole is opened on the top plate on the top of the indicating light source 4, and a downwardly extending flange is connected to the wall of the...

Abstract

The invention discloses a capacitive touch sensor comprising a base with an accommodating cavity, a light-transmitting panel laid on the base, an indicating light source and a circuit board. The indicating light source and the circuit board are positioned in the accommodating cavity, the base comprises a top board and a bottom board, and the accommodating cavity is located between the top board and the bottom board. A light-transmitting hole is formed at the position, corresponding to the indicating light source, of the top board. A condensation barrel is arranged in the accommodating cavity around the indicating light source. A light-transmitting conducting layer is arranged at the position, corresponding to the light-transmitting hole, at the bottom of the light-transmitting panel and is connected to the circuit board through a conductor. The capacitive touch sensor is high in sensitivity, good in sealing effect and high in environmental adaptability.

Description

Technical field [0001] The invention relates to the field of touch sensing keys, and in particular to a capacitive touch sensing device. Background technique [0002] With the development of science and technology, touch sensing technology has increasingly received more attention and applications, and has been increasingly used in applications such as home appliances, handheld devices, industrial control, automotive electronics, and military products. Touch technology can be divided into: resistive touch technology and capacitive touch technology. The signal detected by capacitive touch technology comes from a small change caused by touch. According to different working principles, it can be roughly divided into surface capacitive touch technology (SCT, Surface Capacitive Touch) and projected capacitive touch technology (PCT, Projected Capacitive Touch). Among various technologies, capacitive touch sensing technology has become the mainstream of touch sensing technology. [0003...
