Problems solved by technology

However, even if the light guide structure arranged on the lower circuit board of the membrane switch circuit can be used to guide light, the light guided by the light guide structure on the lower circuit board must further pass through components such as the upper circuit board of the membrane switch circuit and the keyboard frame to be released from the keys. Excessive light loss, which will affect the luminous effect of the keyboard device

Abstract

The invention discloses a light-emitting keyboard device comprising a frame, a plurality of key structures, a line film, a light guide structure, and a plurality of light sources. The frame has a plurality of openings. The key structures are located in the openings. The line film is placed under the frame. The key structure contacts the line film by being pressed. The light guide structure is arranged between the frame and the line film and is adjacent to the key structures. The light sources are arranged on one side of the frame and the line film and emit a plurality of light beams toward the light guide structure so that the light beams are guided to the key structures via the light guide structure. The light-emitting keyboard device can be reduced in overall thickness by eliminating a backlight module. Since the light guide structure is adjacent to the key structures disposed in the frame openings, the light beam can be effectively guided to the key structures so that the light-emitting keyboard device has a good light-emitting effect.

Description

【Technical field】 [0001] The present invention relates to a keyboard device, and in particular to a luminous keyboard device. 【Background technique】 [0002] In recent years, with the increasing development of the technology industry, electronic devices such as notebook computers (notebooks, NBs), tablet computers (tablet PCs) and smart phones (smart phones) and other electronic products have frequently appeared in daily life. The electronic device is usually configured with a processor, a circuit board, a battery, an input / output interface (such as a display panel, a touch panel, a touchpad or a keyboard device) or other suitable electronic components to increase its functionality. For example, the keyboard device can be disposed in the casing of the electronic device and exposed to the operating surface of the electronic device, and the user can operate the electronic device through the keyboard device as an input interface. [0003] The keyboard device usually includes a...
