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.

A keycap for a luminous keyboard comprises a base and a cap made of a transparent material. The base is provided with a first stage, and the top surface thereof is transparent. The cap covers the first stage, and is fixedly connected with the base. The cap is provided with a light-shielding layer, and the surface of which and opposite to the first stage is engraved with a light-transmitting area by laser. A manufacturing method for the same is described. Using the disclosed keycap and the manufacturing method thereof, the operator can accurately and quickly operate the keyboard in a dark environment, making the usage more convenient. As the light-transmitting area in the shape of characters or patterns is not likely to be rubbed or erased, the lifetime of the keycap is prolonged.

The input component includes a molding that forms an external frame, a sensor sheet formed by providing a sensor electrode on a base sheet formed of a resin film, the sensor sheet being installed inside the molding, a display element capable of being illuminated by an internal light source, a light shielding portion that shields a light from the internal light source, the display element being illuminated when the internal light source is on, a contact with the display element enabling an input operation, a colored transparent layer formed so as to have a color tone that creates a blackout in which the display element becomes integrated with the light shielding portion surrounding the display element when the internal light source is off so as to become difficult to perceive, the colored transparent layer being provided so as to be layered on the display element, and a light diffusing layer.

Keycaps for keyboards that have transparent top portions have a set of layered components to define a top surface that provides key definition by curvature, texture, ridges, or other external structural features. Other portions of the keycaps define a glyph or support structure for the top layer. Features such as angle filters and partially reflective materials are implemented to improve the visibility, contrast, and reflectivity of the keycaps. Multiple methods are used to bend or otherwise modify rigid transparent materials such as glass in order to add surface features and to improve aesthetics of the keycaps of a keyboard.

A keyboard includes a backlight module, a base plate, a membrane circuit disposed on the base plate, and a plurality of key structures disposed on the membrane circuit. The backlight module includes a light source, a reflective layer, a light guide layer, and a shielding layer. The light source is disposed corresponding to the light guide layer. The light guide layer is located between the shielding layer and the reflective layer. The light guide layer has a through-hole. The shielding layer and the reflective layer are in contact with each other in the through-hole of the light guide layer. The base plate is disposed on the shielding layer. The base plate has a positioning portion disposed corresponding to the through-hole of the light guide layer, which protrudes toward the reflective layer or the membrane circuit.

A keyboard including a backlight module, a base plate disposed on the backlight module, a membrane circuit disposed on the base plate, and a plurality of keycaps disposed on the membrane circuit is provided. The backlight module includes a light source and a reflective layer. The light source and a corresponding circuitry are arranged on the reflective layer, and a circuitry connecting portion extends from the reflective layer. The base plate has a positioning portion with an aperture, and a portion of the reflective layer contacts the base plate or the positioning portion.

An apparatus for entering alphabetic data into a computer or other electronic or mechanical devices with a keyboard, wherein the keys are placed in an ordered arrangement. The vowels AEIOU are grouped together and arranged on a left side of the keyboard. The vowels are arranged in alphabetic order vertically across the three rows of keys with letters AE on the top row, the letters IO on the middle row, and the letter U on the bottom row. Each of the vowels has a same color. Consonants are arranged in consonant groups comprised of BCD, FGHJK, LMNPQ, RST, and VWXYZ. The consonant groups are arranged from left to right in alphabetic group order. The consonants in each of the consonant groups are arranged vertically across the three rows of the keys. The key groupings may also be differentiated by color.

A light-pervious bicolor key cap includes: a key frame, having a first color and formed with plural thin ribs, wherein front ends of the plural thin ribs are formed with at least one letter or punctuation in a continuous status without any notch; and a cap cover, having a second color, wherein the letter or punctuation is formed on a surface of the cap cover, an outer side of the cap cover is formed with a material filling protrusion allowing a plastic having the second color to be filled in, and an inner surface thereof is formed with at least one convex piece which is not fixedly combined with the key frame; so that through removing the convex piece having the second color, the letter or punctuation of the cap cover is prevented from being formed with any notch and capable of allowing the light to fully permeate.

A direct-backlit keyboard is disclosed, the direct-backlit keyboard comprising a plurality of keys, a thin film circuit board, a base plate, a copper etched thin-film circuit board, and a plurality of light-emitting units. The plurality of keys are disposed on the thin film circuit board, the thin film circuit board being disposed on the base plate, the base plate being disposed on the copper etched thin-film circuit board, and the copper etched thin film circuit board being provided with the plurality of light-emitting units. Each light-emitting unit corresponds to each key so that the light emitted from each light-emitting unit can be transmitted to each corresponding key.
