An illuminated keyboard includes a membrane circuit board, a base plate, a key structure, a backlight module and a first reflective layer. The base plate is disposed beneath the membrane circuit board and has a first through hole and a plurality of second through holes adjacent to the first through hole. The key structure is disposed over the membrane circuit board and includes an elastic member. The backlight module is disposed beneath the base plate. The backlight module includes: a direct-type light-emitting element, substantially aligned with the first through hole and misaligned with a trigger portion of the elastic member; and a light guide plate, laterally adjacent to the direct-type light-emitting element. The first reflective layer is disposed over, beneath, or over and beneath the membrane circuit board and is substantially aligned with the first through hole.

Illuminated keyboard

An input device with a backlight function and a backlight color adjustment method are provided. The input device with the backlight function includes a casing, plural color light-emitting elements, a control module and a charge-coupled device. The control module provides electric power to at least two selected color light-emitting elements through a power supply circuit. By the control module, the chromaticity value of a mixed white light beam from the color light-emitting element is adjusted to be consistent with the chromaticity value of a white light beam, and the luminance value of the mixed white light beam from the color light-emitting element is adjusted to be consistent with the luminance value of the white light beam.

Input device with backlight function and backlight color adjustment method thereof

A keyboard device includes a keyboard module and an illumination module. The keyboard module includes plural first keys and at least one second key. The illumination module includes a light guide plate and a circuit board. The light guide plate includes plural first mapping zones and a second mapping zone. The first mapping zones are located under the corresponding first keys. The second mapping zone is located under the second key. Moreover, at least one side-view light-emitting element and at least one top-view light-emitting element are installed on the circuit board. The side-view light-emitting element emits a first light beam. The top-view light-emitting element emits a second light beam. The first light beam is extracted through the corresponding first mapping zone and transferred to the corresponding first key. The second light beam is transferred to the second key.

Keyboard device capable of producing multi-zone lighting effect and illumination module thereof

A color adjusting method for a color light-emitting element is provided. Firstly, a first white light beam is produced by red, green and blue light-emitting units collaboratively, and a second white light beam is produced by a white light-emitting unit. Then, a second chromaticity value corresponding to the second white light beam is acquired. Then, the red, green and blue light-emitting units are controlled to produce a third white light beam according to the second chromaticity value, and a first adjusting parameter is acquired. Then, the white light-emitting unit is controlled to produce a fourth white light beam according to a third luminance value corresponding to the third white light beam, and a second adjusting parameter is acquired. Then, a gray level adjustment process is performed according to the first and second adjusting parameters.

Color adjusting method for color light-emitting element and input device with color adjusting function

An input device includes a universal serial bus interface, a white light-emitting diode unit, a red light-emitting diode unit, a green light-emitting diode unit, a blue light-emitting diode unit and a driving part. The driving part receives electricity through the universal serial bus and drives at least one of the white light-emitting diode unit, the red light-emitting diode unit, the green light-emitting diode unit and the blue light-emitting diode unit to emit a light beam. Consequently, the light beam with a higher luminous intensity and a specified color is outputted from the input device.

The present invention provides a keyboard device, including a plurality of keys, thin film circuit boards, and key bottom plates. A connection component of the key is connected between a keycap of the key and a bottom plate connection portion of key bottom plate, and the bottom plate connection portion has a connection portion surface corresponding to the keycap and a raised portion formed on the connection portion surface. When the keycap moves downward relative to the thin film circuit board, a lower surface of the keycap knocks the raised portion.

Keyboard device

This application provides a luminous keyboard, including a plurality of keys, a plurality of keys, a light guide plate, and a reflector. Each of the keys includes a rubber dome, where the rubber dome is made of a translucent material doped with a plurality of light-diffusion particles, and when the rubber dome is irradiated by a light ray, a part of the light ray is diffused when traveling upward through the rubber dome, and the other part of the light ray is reflected downward by the rubber dome to the reflector, then, is reflected upward, and is diffused when passing by a plurality of light diffusion protrusions of the light guide plate, to be emitted outward through the keys.
