Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, fig. 2A, fig. 2B, fig. 3A, and fig. 3B, fig. 1 is a top view of a keyboard apparatus 100 according to an embodiment of the invention, fig. 2A is a top view of a second key module 20 of the keyboard apparatus 100 of fig. 1, fig. 2B is a cross-sectional view of the second key module 20 of fig. 2A along a direction 2B-2B ', fig. 3A is a top view of a first key module 10 of the keyboard apparatus 100 of fig. 1, and fig. 3B is a cross-sectional view of the first key module 10 of fig. 3A along a direction 3B-3B'.
The keyboard apparatus 100 may be a stand-alone keyboard or a keyboard integrated with an electronic device, such as a host computer of a notebook computer.
The keyboard apparatus 100 includes a circuit board 110, a plurality of first light emitting members 120, at least one second light emitting member 130, a plurality of first switches 140, at least one second switch 150, a controller 160, a plurality of key caps 170, and a driver 180. The keyboard device 100 includes a plurality of first key modules 10 and at least one second key module 20. As shown in fig. 2A and 2B, a second light emitting element 130, a second switch 150 and a key cap 170 form a second key module 20, and a first light emitting element 120, a first switch 140 and a key cap 170 form a first key module 10, wherein the mechanism of the first key module 10 is similar to or the same as that of the second key module 20. In one embodiment, the sum of the number of the first key modules 10 and the number of the second key modules 20 may be less than, equal to, or greater than 50.
As shown in fig. 2A to 3B, the first light emitting element 120 and the second light emitting element 130 are disposed on the circuit board 110. The plurality of first switches 140 are disposed corresponding to the plurality of first light-emitting elements 120 (for example, a first key module 10 includes the corresponding first switch 140 and the corresponding first light-emitting element 120). The second switch 150 is disposed corresponding to the second light emitting element 130 (for example, a second key module 20 includes the corresponding second switch 150 and the second light emitting element 130). The controller 160 is configured to: (1) controlling the first light emitting elements 120 to emit light in a first light emitting mode; (2) when the second switch 150 is triggered, the second light emitting element 130 is controlled to selectively emit light in one of a first light emitting mode and a second light emitting mode, wherein the first light emitting mode and the second light emitting mode are different. In one embodiment, the first light emitting mode and the second light emitting mode may or may not occur simultaneously.
Thus, a user can selectively emit light in one of the first light emitting mode and the second light emitting mode through the second light emitting element 130 to identify the position of the specific key. For example, when the second key module 20 is preset as a specific key, such as one of a case Lock key (Caps Lock), a keypad Lock key (Num Lock) or a Scroll Lock key (Scroll Lock), since the light emitting mode (e.g., the second light emitting mode) of the second light emitting element 130 of the second key module 20 is different from the light emitting mode (e.g., the first light emitting mode) of the first light emitting element 120 of the first key module 10, a user can quickly find the specific key through the different light emitting modes.
In one embodiment, the first light emitting mode is, for example, a "special effect light mode", and the second light emitting mode is, for example, an "indicator light mode". For example, the "special effect light mode" is that the light color and/or brightness of the first light-emitting elements 120 of the plurality of first key modules 10 are changed continuously, and for example, the light color and/or brightness of the second light-emitting elements 130 of the second key module 20 are obviously different from the "special effect light mode". For example, in the first light emitting mode, the light color of the first light emitting elements 120 adjacent to the second light emitting element 130 varies with time; in the second light emitting mode, the color of the second light emitting element 130 is not changed. Thus, the light color of the first light emitting element 120 changes, and the light color of the second light emitting element 130 remains unchanged, so that the position of the second key module 20 can be found visually and quickly.
In another embodiment, in the first light emitting mode, the light emission of the first light emitting elements 120 adjacent to the second light emitting element 130 flickers with time; in the second light emitting mode, the light emission of the second light emitting member 130 does not flicker with time. In this way, the location of the second key module 20 can be found visually and quickly with whether to blink.
As shown in fig. 2A and 2B, in a second key module 20, a second switch 150 is, for example, a blocking element, and includes an optical transmitter 151 and an optical receiver 152. The controller 160 is electrically connected to the optical transmitter 151 and the optical receiver 152, and the controller 160 controls the optical transmitter 151 to continuously transmit the optical signal to the optical receiver 152. The key cap 170 includes a trigger part 171, and the position of the trigger part 171 corresponds to the area between the light emitter 151 and the light receiver 152. Thus, when the key cap 170 is pressed downward, the triggering portion 171 can interrupt the optical signal between the optical transmitter 151 and the optical receiver 152, and the controller 160 detects the interruption and determines that the second switch 150 is triggered (the key cap 170 is pressed), thereby executing the corresponding function.
As shown in fig. 2A and 2B, in one second key module 20, the second light emitting element 130 is disposed at a position corresponding to an area between the light emitter 151 and the light receiver 152. The key cap 170 is located right above the second light emitting element 130, and the key cap 170 has a light-transmitting portion 172, so that the light emitted from the second light emitting element 130 can penetrate through the light-transmitting portion 172. In this way, even if key cap 170 completely covers second light emitting member 130, the position of second key module 20 can be quickly found out from the light emission of light-transmitting portion 172 of second key module 20.
As shown in fig. 3A and 3B, in a first key module 10, a first switch 140, such as a cut-off element, includes a light emitter 141 and a light receiver 142. The controller 160 is electrically connected to the optical transmitter 141 and the optical receiver 142, and the controller 160 controls the optical transmitter 141 to continuously transmit the optical signal to the optical receiver 142. The key cap 170 of the first key module 10 includes a triggering portion 171, and the position of the triggering portion 171 corresponds to the area between the light emitter 141 and the light receiver 142. Thus, when the key cap 170 is pressed downward, the triggering portion 171 can interrupt the optical signal between the optical transmitter 141 and the optical receiver 142, and the controller 160 detects the interruption and determines that the first switch 140 is triggered (the key cap 170 is pressed), thereby executing the corresponding function.
As shown in fig. 3A and 3B, in one first key module 10, the arrangement position of the first light-emitting element 120 corresponds to the area between the light emitter 141 and the light receiver 142. The key cap 170 is located right above the first light emitting element 120, and the key cap 170 has a light-transmitting portion 172, so that the light emitted from the first light emitting element 120 can penetrate through the light-transmitting portion 172 to present a special effect light mode of the first key module 10.
Please refer to fig. 4, which is a functional block diagram of the keyboard apparatus 100 of fig. 1. The driver 180 is electrically connected to the controller 160 through an Integrated Circuit (I2C) 165. The controller 160 may control the driver 180 to drive the first and second light emitting elements 120 and 130 to emit light. The first and second light emitting elements 120 and 130 are connected to the driver 180, such that the driver 180 directly controls the first and second light emitting elements 120 and 130, rather than the controller 160 directly controlling the first and second light emitting elements 120 and 130.
In addition, the controller 160 is used for responding to the first light emitting mode command and controlling the second light emitting element 130 to emit light in the first light emitting mode; in response to the second light-emitting mode command, the second light-emitting member 130 is controlled to emit light in the second light-emitting mode. For example, the controller 160 is used to detect whether the second switch 150 is triggered; when the second switch 150 is triggered, the light emitting mode of the second light emitting member 130 is determined; when the light emitting mode of the second light emitting element 130 is the first light emitting mode, controlling the second light emitting element 130 to emit light in the second light emitting mode; and controlling the second light emitting element 130 to emit light in the first light emitting mode when the light emitting mode of the second light emitting element 130 is the second light emitting mode. In detail, when the second switch 150 is triggered once, the light emitting mode of the second light emitting element 130 is changed to one of the first light emitting mode and the second light emitting mode; when the second switch 150 is triggered again, the light emitting mode of the second light emitting element 130 is changed to be the other of the first light emitting mode and the second light emitting mode.
In summary, the keyboard apparatus of the present invention includes a plurality of first light emitting elements, a plurality of second light emitting elements, a plurality of first switches, a plurality of second switches, and a controller. Controlling the plurality of first light emitting members to emit light in a first light emitting mode by the controller; and controlling the second light-emitting element to selectively emit light in one of the first light-emitting mode and the second light-emitting mode, so that the first light-emitting mode is different from the second light-emitting mode. The specific key is made to present a specific light-emitting mode, and a user can quickly find a specific key according to the specific light-emitting mode.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
