Conductive slurry, waterproof pressing structure, circuit membrane and fabrication method thereof

The present disclosure is related to a touchpad structure, which includes a cover plate, a backlight unit, a touch circuit layer, a first optical modulation layer, and a second optical modulation layer. The first optical modulation layer is disposed between the cover plate and the backlight unit, and having a first reflectivity. The second optical modulation layer is disposed between the first optical modulation layer and the touch circuit layer. The second optical modulation layer has a second reflectivity and a first penetration rate, wherein the second reflectivity is the same as the first reflectivity, or the first reflectivity is the same as the first penetration rate. The touchpad structure can present a uniform color spectrum via the second optical modulation layer and the first optical modulation layer.

Touchpad structure

A waterproof pressing structure including a first membrane, at least one first contact, a second membrane, at least one second contact, an insulation layer and a hydrophobic material is provided. The first contact is located on the first membrane, the second contact is located on the second membrane, and the insulation layer is interposed between the first membrane and the second membrane, wherein the first membrane, the second membrane and the insulation layer are stacked in a vertical direction, and the hydrophobic material is respectively formed on the two surfaces of the first contact and the second contact to form a low surface tension zone between the first contact and the second contact.

Waterproof pressing structure and membrane switch circuit board using the same

The disclosure provides a key structure, including a carrier, a buffer layer, a circuit film, a balance rod and a key cap. The carrier includes a body and a positioning element protruding from the body. The positioning element has a positioning hole. The buffer layer is disposed around the positioning hole. The circuit film and the balance rod are disposed on the body. The balance rod has an opposite first end portion and a second end portion. The first end portion passes through the positioning hole and presses against the buffer layer. The key cap is connected with the second end portion, and the circuit film and the balance rod are positioned between the key cap and the body.

Key structure

A keyboard key structure includes a plurality of keycaps. Each keycap has a keycap body and an outward layer. The keycap body has an appearance with a first color. The outward layer has an appearance with a second color different from the first color. The outward layer is formed above the keycap body. The outward layer is formed with an engraving portion. The first color is exposed in the engraving portion. The present invention also provides a method of manufacturing a keycap of a keyboard key.
