Structure of notebook computer illuminant keyboard

Abstract

The invention discloses a structure of a notebook computer illuminant keyboard, which comprises a substrate, a light guide plate, a flexible circuit board, a silicone keypad, a scissor foot and a keycap. The light guide plate is fixed on the substrate, the flexible circuit board is fixed on the upper layer of the light guide plate through a hook of the substrate, the front face of the flexible circuit board is provided with light reflection printing ink, the silicone keypad is directly pasted on the flexible circuit board, the keycap is connected with the substrate through the scissor foot, a light-emitting diode (LED) lamp providing a power supply for the light guide plate is pasted on the back face of the flexible circuit board, two layers of printing ink are arranged on the front face of the light guide plate, the printing ink at the bottom layer is white or mirror plane silver used for increasing light reflection, and the printing ink at the top layer is black used for shading towards the upward direction. The previous front face flat design of the light guide plate is changed to the design with mechanical holes, the light reflection layer and the shading layer are additionally arranged on the front face of the light guide plate, an illuminant layer is additionally arranged on the front face of the flexible circuit board, and materials of a back light plate, a power circuit, a shading piece and the like on the previous keyboard design are reduced.

Description

technical field [0001] The invention relates to the field of notebook computers, in particular to a structure of a light-emitting keyboard for notebook computers. Background technique [0002] If the keyboard of the existing notebook computer needs to emit light, it basically adopts a metal-based flexible circuit board (FPC) plus a light source (SMD LED lamp) plus auxiliary materials such as a light guide plate, and attaches it to the back of an ordinary keyboard. Not only the cost is high, but also the thickness of the keyboard is increased. Since the light source needs to be powered separately, the computer motherboard also needs the module to provide power and connection positions for it, which also occupies the design space of the motherboard to varying degrees. Contents of the invention [0003] The purpose of the present invention is to overcome the defect of the existing luminous keyboard on the thickness of the keyboard, which causes the space limitation of the ult...
