Abstract

The invention relates to a thin light-emitting keyboard. The thin light-emitting keyboard comprises a light-emitting unit, a circuit board, a bottom plate, a backlight module assembly and a bearing structure. The circuit board is coupled to the light-emitting unit and transmits electric signals which can drive the light-emitting unit; a concave part and a first opening are formed on the bottom plate, wherein the concave part is communicated with the first opening; the backlight module assembly is arranged at a first side of the bottom plate and is used for guiding light emitted by the light-emitting unit; the bearing structure is formed in the concave part, and two sides of the bearing structure face the concave part and the first opening respectively, and the bearing structure is used for bearing the circuit board such that the circuit board can be accommodated in the concave part; and when the bearing structure bears the circuit board, the light-emitting unit is embedded in the backlight module assembly through the first opening. The thin light-emitting keyboard of the invention accords with the development trend of the thinning of light-emitting keyboards.

Description

technical field [0001] The invention relates to a luminous keyboard, in particular to a thinned luminous keyboard. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, with the improvement of consumers' visual demands, a luminous keyboard has become a new development direction of the industry. Generally speaking, the luminous keyboard uses a side-lit backlight module as its light source, that is, the light-emitting diode and its flexible circuit board used to emit light are attached under the bottom plate and the backlight module is embedded on the side of the light guide plate. In this way, the light emitted by the light-emitting diode can enter the light guide plate from the side of the light guide plate and be guided by the light guide plate to project toward the keycap. However, since the light-emitting diode and its fl...
