Using organic light emitting diode (OLED) film to illuminate keycaps of keys in a keyboard

In some examples, a computing device may include a first housing and a second housing. The first housing may include a first set of components, such as a display device. The second housing may include a second set of components, such as a keyboard having a plurality of keys. An individual key of the plurality of keys may include a keycap, an organic light emitting diode (OLED) film (or sheet), a key mechanism, and a base. When power is provided to contacts on the base of the individual key, the power may travel across conductive traces (or wires) in the key mechanism to pads on the OLED film, causing the OLED film to emit light. The light from the OLED film may illuminate a character or symbol embedded into the keycap or the OLED film may be shaped into the character or the symbol and embedded into the keycap.

Low profile keyboard backlight module

A low profile keyboard backlight module includes an electrically insulative bottom membrane layer, an intermediate membrane layer including a conducting layer, an insulative layer and a light-emitting layer attached together through lamination and bonded to the top surface of the bottom membrane layer, and an electrically insulative top membrane layer bonded to a top surface of the intermediate membrane layer opposite to the bottom membrane layer and having an integrated elastic layer located at a top surface thereof to support a set of keys. Thus, the low profile keyboard backlight module provides optimal waterproof effects and is practical for use in an electronic product having light, thin, short and small characteristics.

Light emitting keyboard

A light emitting keyboard is provided. The keyboard includes: a plurality of keys, wherein each of the keys has a light source; and a controller, for turning on the light source of at least one second key when a user presses one of the plurality of keys.

Uniform illumination of keys

Systems and methods for providing illumination to illuminable portions of keys associated with a keyboard are described. A key includes a light guide positioned below a keycap. The light guide includes one or more sidewalls that exhibit high internal reflection. In many examples, light guide sidewalls are formed with one or more prisms.

Button with flexible light conductor

A button assembly configured to be illuminated is provided. The button assembly includes a movable button having a viewing surface and a back side. The button has portions defining a window in the viewing surface. A flexible light conductor is disposed on the back side of the button. The flexible light conductor has an inlet end configured to receive light, and the flexible light conductor has a light-emitting portion disposed adjacent to the window. The flexible light conductor is configured to conduct light from the inlet end to the light-emitting portion. The light-emitting portion is configured to emit light so that the light is visible through the window.

A light color changeable illuminated keyboard includes a circuit layer, plural keys, a switching key, a bicolor light-emitting element and a control unit. The plural keys and the switching key are disposed on the circuit layer. The bicolor light-emitting element is located under the plural keys. The bicolor light-emitting element selectively emits a first color light or a second color light. The control unit is electrically connected with the switching key and the bicolor light-emitting element. If the switching key is pressed down when the bicolor light-emitting element emits the first color light, a pressing signal is generated. In response to the pressing signal, the color light emitted by the bicolor light-emitting element is switched from the first color light to the second color light under control of the control unit.

Keyboard

A keyboard includes a base plate, a pressure sensing layer, a first key structure and a second key structure. The pressure sensing layer includes plural pressure sensing regions. Each of the first key structure and the second key structure corresponds to a pressure sensing region. Moreover, the first key structure and the second key structure are located over the corresponding pressure sensing regions. In response to different magnitudes of the depressing force, the corresponding pressure sensing regions are pushed by the first key structure and the second key structure. Consequently, the corresponding pressure sensing regions generate different pressure sensing signals. The pressure sensing layer can replace plural pressure sensing element. Consequently, the assembling process is simplified, and the assembling cost is reduced.
