Description

Illuminated keyboard device

technical field

The present invention relates to a keyboard device, in particular to a keyboard device with a light-emitting function.

Background technique

Common computer peripheral input devices include mouse devices, keyboard devices, and trackball devices. Among them, the keyboard device can directly input characters and symbols to the computer, so it is highly valued by users and input device manufacturers. In order to operate the keyboard in a dark environment, various input device manufacturers currently use a cold light panel inside the keyboard device and use it as a light source. When the cold light panel is supplied with power, the cold light panel is driven to emit a light beam. , so that the keyboard device presents a luminous effect. However, this type of cold light panel can only emit a single color light beam, so that the existing luminous keyboard device can only present a single luminous color. Another existing method is to install a light emitting diode (Light Emitting Diode, LED) under each button as a point light source. However, installing an LED under each key not only has the problem of high cost, but also causes the problem of poor heat dissipation of the light-emitting keyboard device.

In order to solve the above two problems, Taiwan Patent Publication No. TW200945113 discloses a luminous keyboard device.

The light beam of the second color (such as blue light), and the light beam of the second color is projected on the second light guide area 224, wherein the light shielding area 226 blocks the first light guide area 222 and the second light guide area 224, so that the light beam of the first color The beams of light and the beams of the second color do not mix with each other.

The masking element 210 has a preset pattern for being penetrated by the light beam of the first color or the light beam of the second color generated by the first light emitting element 240 or the second light emitting element 250 so as to reduce the scattering of the light beam, wherein the masking element The 210 can use light-shielding pigments or resin films coated with light-shielding pigments, such as polyethylene terephthalate (PET) films or polyvinyl chloride (PVC) films. The cover element 210 has a plurality of openings 215, and the positions of the plurality of openings 215 correspond to the positions where the plurality of keys want to emit light, so that the light beam guided by the light guide element 220 can be projected to the corresponding keys (such as buttons 112 and 114). Moreover, in order to prevent the beam from being scattered by the gaps between the keys, the plurality of openings 215 on the masking element 210 can be designed to be slightly smaller than the size of the key surface, as shown in FIG. 2 .

The light guide plate 220 is located under the shielding element 210 and is used to guide the light beams of the first color and the light beams of the second color as a light transmission medium.

On the other hand, at least one second light-emitting element 250 is disposed in each second light-guiding area 224, so that the light beam of the second color generated by the second light-emitting element 250 can be guided through the second light-guiding area 224, and Through the opening 215 above the second light guide area 224 , the key corresponding to the second light guide area 224 in the key module 100 (such as the key 114 ) is displayed in the second color. The position, size, quantity distribution, etc. of the second light guide area 224 can be determined according to the position of the key corresponding to the light of the second color, for example, it is located under the letter keys of the W key, the A key, the S key, and the D key and presents It is a convex font, and it is located under the blank bar to form a rectangle, etc. The reflective sheet 230 is located under the light guide plate 220 to reflect the light beam of the first color or the light beam of the second color scattered by the light guide element 220 for reuse, so as to improve light usage efficiency and avoid light beam scattering.

The first light-emitting element 240 and the second light-emitting element 250 are light-emitting diodes that can generate light of different colors, so that the button module 100 can display different colors at preset positions. For example, the first light-emitting element 240 can be a white light-emitting diode, and the second light-emitting element 250 can be a blue light-emitting diode, then the button module 100 will have a first color block (such as the button 112) showing white light and blue light.
