摘要： Systems and methods for illuminating a keycap on a keyboard are described. One system comprises a first light source positioned below the keycap on the keyboard and arranged to illuminate a portion of a bottom of the keycap. The system also comprises a second light source, adjacent the first light source, positioned below the keycap and arranged to illuminate a portion of the bottom of the keycap. One method of illuminating a keycap on a keyboard comprises activating a first light source, wherein the first light source and a second light source are positioned below the keycap on the keyboard, and activating the second light source responsive to the first light source operating outside a predetermined threshold parameter.

摘要： A backlighting device (300, 400, 500, 600) emitting light having a first wavelength includes a first radiation emission device (302), e.g., an electroluminescent lamp, for emitting radiation having a second wavelength. A layer (306) of a plurality of photon emitting particles (308), e.g., free standing quantum dots or phosphorus particles, emits light having the first wavelength in response to the first radiation emission device (302), the first wavelength being larger than the second wavelength. A transparent material (116, 120, 122) overlies the layer of a plurality of photon emitting particles (308), wherein the light having a first wavelength passes through the transparent material (116, 120, 122). Optionally, a filter (402) may be placed over the layer (306) to block the radiation having a second wavelength, and a scattering layer (604) may be placed over the layer (306) to scatter wavelength other than the first wavelength.

摘要： A vehicle interior component and lighting assembly that includes a vehicle interior component having a fabric disposed over a substrate or foam layer, or both. An electroluminescent panel is located between the fabric and substrate/foam layer and directs light from the panel through the fabric. In this way, the light source can be effectively hidden when not in use and can be incorporated into the interior component in a manner that requires little space. The vehicle interior component can be any of a number of different interior articles, including, for example, a headliner, door panel, vehicle seat, rear deck, sun visor, and trunk panel. Also disclosed are vehicle interior illumination systems using touch switches and electroluminescent panels to provide back lighting of the switch and/or vehicle interior illumination through the switch.

摘要： An electroluminescent keyboard includes a plurality of membrane switch structures, a plurality of keycaps, a plurality of electroluminescent elastic members, and an electrode layer. The electroluminescent elastic members are arranged between the keycaps and respective membrane switch structures for emitting light in response to an electric current or an electric field. The electrode layer is arranged between the electroluminescent elastic members and respective membrane switch structures and electrically connected to respective electroluminescent elastic members. The electroluminescent elastic members emit light when the electric current passes through the electrode layer or the strong electric field is applied to the electrode layer. The light-emitting element and the backlight module that are used in the conventional keyboard are not included in the electroluminescent keyboard. In addition, the light could be effectively controlled to be guided to a desired luminous region of the keycap. As a consequence, the illuminated keyboard is very cost-effective.

摘要： Methods are provided for adapting existing manufacturing processes for non-illuminated data-entry devices and mouses to the manufacture of illuminated data-entry devices. Luminescent sheets of one or more colors underlying optically transmissive device components provide illumination of the components visual to a user of the device. The optically transmissive components may be doped with phosphors or tinted to provide components that emit light of different colors. The intensity of illumination of the luminescent sheet may be controlled by the user and may vary in response to the background light of the environment.

摘要： Mobile phones are in a trend of having thinner configuration due to emphasis on the design. Thus, in order to meet this demand, the present invention aims to thin the key sheet portion as much as possible. A thin key sheet and a thin key unit incorporating the thin key sheet are configured by providing on its surface a key top 2 made of a metal or a resin with indications such as letters, symbols, graphics or the like indicating the functions of keys are formed on the front surface or the back surface thereof, and switch elements 4 for turning ON/OFF of an electric circuit by the pressing of the key top, together with a printed circuit board 5 on which a circuit pattern involved therewith is formed; and by adhering and fixing the key top 2 and the printed circuit board 5 together via a cushion gasket 3 having appropriate elasticity and a filler layer 14 disposed between the key top and the printed circuit board.
