▎ 摘　　要

NOVELTY - Light-emitting keyboard has a thin-film circuit board, a keycap, a light-transmitting elastic member and a light-emitting device, where the keycap and the light-emitting device are respectively located on both sides of the thin film circuit board in the thickness direction, the keycap has a light-transmitting portion, the keycap is movable relative to the thin-film circuit board in the thickness direction of the thin-film circuit board to switch between the pressed position and the release position, the elastic member resists the connection between the keycap and the film circuit board, the elastic member includes a trigger portion, the thin film circuit board includes a transparent substrate and a transparent switch, the switch is arranged on the substrate and is opposite to the trigger part and the part of the light generated by the light emitting device is passed through the switch. USE - Light-emitting keyboard for electronic device (claimed) such as tablet personal computer, laptop computer, personal digital assistant, personal computer, notebook computer and in-vehicle equipment. ADVANTAGE - The light-emitting keyboard has improved backlight effect and light transmission effect, enhanced light of the keycap, saves the space occupied by the light emitting device and the backlight module, desired compactness, simplified structure, optimized structure layout, improved utilization rate of light emitted by light emitting devices, improved light guide effect by providing light guide hole opposite to the switch and reduced size and weight. DETAILED DESCRIPTION - Light-emitting keyboard has a thin-film circuit board 4, a keycap 2, a light-transmitting elastic member and a light-emitting device, where the keycap and the light-emitting device 7 are respectively located on both sides of the thin film circuit board in the thickness direction, the keycap has a light-transmitting portion, the keycap is movable relative to the thin-film circuit board in the thickness direction of the thin-film circuit board to switch 42 between the pressed position and the release position, the elastic member resists the connection between the keycap and the film circuit board, the elastic member includes a trigger portion, the thin film circuit board includes a transparent substrate and a transparent switch, the switch is arranged on the substrate and is opposite to the trigger part, the part of the light generated by the light emitting device is passed through the switch, the elastic member is injected into the light-transmitting part, the trigger part contacts the film circuit board in the pressed position of the keycap to trigger the switch, and the trigger portion is spaced apart from the thin film wiring board in the release position of the keycap. An INDEPENDENT CLAIM is included for an electronic device, which comprises a motherboard, the light-emitting keyboard and thin-film circuit board and light-emitting device that are electrically connected to the motherboard.
