The illuminated keyboard is a backlit keyboard. The illuminated keyboard comprises a keyboard and a switching network that generates the back lit illumination of the keyboard. The switching network divides the keyboard in to a plurality of zone displays. Each of the plurality of zone displays is used to illuminate a region of the keyboard. Each of the plurality of zone displays is independently controlled. Each of the plurality of zone displays further comprises a plurality of LEDs. Each LED contained within the plurality of LEDs is independently controlled and illuminated. Each LED selected from the plurality of LEDs is differentiated from the LEDs remaining within the plurality of LEDs by the illumination color of the selected LED. The illuminated keyboard comprises a keyboard, a switching network, and a network controller. In one potential embodiment of the disclosure, the illuminated keyboard is remote controlled.

An illuminated keyboard is provided with a plurality of key caps, a plurality of bridge structures, a plurality of hollow, resilient domes, a frame board, a membrane circuit board, a reflective layer, and a light transmissive membrane including a plurality of light-emitting diodes (LEDs), printed circuits, and a plurality of recesses. The key caps are uniformly illuminated.

A panel for an electronic device, with a front side, and a back side. The panel including a sign, suitable to be viewed from the panel's front side, wherein the sign has an annular shape. The sign has 3 indicia mit light, each being an annular segment of the annular shape, each with an angular length, and further each two adjacent indicia mechanisms are spaced by an angular gap alpha, and wherein 0<=alpha is <=20.

An illuminated keyswitch includes a base, a keycap, a lift mechanism, and a light source. The keycap includes a cap body and a light guiding rod. The lift mechanism is connected to between the light guiding rod and the base, such that the keycap can vertically move relative to the base through the lift mechanism. The light source is disposed between the light guiding rod and the base and emits light toward the light guiding rod. The light enters the light guiding rod through an end portion of the light guiding rod and then emits out the light guiding rod from another end portion of the light guiding rod and a side surface adjacent to the another end portion toward the cap body. Thereby, the whole cap body can receives relatively uniform back light.

A switch, keyboard and associated methods are provided. In one implementation, the switch includes a housing having a protruding portion configured to be received in an aperture formed on a substrate, a plunger operable to move with respect to the housing, a first contact member located in the housing, and a second contact member extending from the protruding portion of the housing. The second contact member is operable to, based at least in part on the plunger being moved in a first direction, deform to a predefined extent to electrically contact the first contact member. The switch provides a low profile appearance but not compromising the smooth and quickly responsive striking motion for a mechanical switch, such that a clean design can be provided while the input experience and durability are maintained. A keyboard is also provided.

A keyboard structure, including: a keycap; a transparent membrane layer; and an elastic element, disposed between the keycap and the transparent membrane layer and having a press portion, where the transparent membrane layer includes: a first opening corresponding to the keycap; a hard membrane layer, having an extension portion that is formed at an inner edge of the first opening inner edge; and a spacer layer, disposed under the hard membrane layer and used for forming a gap. When the keycap is pressed with an external force, the elastic element is deformed to enable the press portion to move downward and abut against the extension portion, so that the extension portion generates a bending deformation in the gap; and when the external force is released, the elastic element and the extension portion are elastically recovered and the extension portion generates a sound.

A portable electronic device having several features is disclosed. The device can include a retention member that retains flexible circuits extending from a top portion to a bottom portion of the device, thereby allowing some components to be moved from a top portion of the device to a bottom portion. The device may include a cover plate can be secured with a display in the top portion to cover the retention member and other internal components. The device can include an omni-directional port designed to receive a connector different orientations and provide power to the device. The device can include a flexible keyboard having butterfly keycaps. The device can include an array of openings for an audio driver, with some of the array including through holes and blind holes. The device can also include a touch pad having a force feedback sensor and a haptic device.

A control device configured for use in a load control system to control one or more electrical loads external to the control device may include a first switch member and a second switch member. The control device may include an actuation member having an upper portion and a lower portion. The actuation member may be configured to actuate the first switch member and the second switch member in response to tactile actuations of the upper portion and the lower portion. The actuation member may include first and second pivot arms that enable the actuation member to pivot about a pivot axis in response to the tactile actuations. The first pivot arm may define a notch. The control device may comprise a light pipe configured to conduct light emitted by a light source through the notch to a light indicator located on the bezel.

A computing system may include a keyboard and at least one backlight. The keyboard may include at least one key. The at least one key may include a first filter shaped according to a first character in a first alphabet. The first filter may transmit light within a first spectral range. The at least one key may also include a second filter shaped according to a second character in a second alphabet. The second filter may transmit light within a second spectral range. The at least one backlight may be configured to shine light of a first wavelength within the first spectral range in response to an instruction to display the first alphabet, and shine light of a second wavelength within the second spectral range in response to an instruction to display the second alphabet.

Systems and methods are disclosed that may be implemented to provide keycap lighting to a spring loaded mechanical key switch assembly using a light conductive structure, such as a light pipe, and without requiring a chassis housing of the mechanical key switch assembly to include a dedicated power-consuming light source mounted to or otherwise positioned at the location of the individual key switch assembly chassis housing. Additionally, the disclosed systems and methods may be implemented to use one or more common power-consuming light source/s to simultaneously provide key cap lighting to multiple such spring loaded mechanical key switch assemblies, for example, by feeding light to each key cap though a common light spreader and through an individual non-power consuming light pipe provided for each key switch assembly.
