Disclosure of Invention

In the combining process of the touch control board and the light-emitting module, the light leakage, the glue spreading and the light effect mutual strings are carried out on the periphery of the original design light-emitting module under the condition that the thickness of the whole module is basically consistent, so the utility model provides the touch control light-emitting module, in particular to the peripheral light-free touch control module with independent light emission in each area.

The utility model provides a touch light-emitting module, which comprises a touch panel, a shading sheet, a light-guiding module, a shading structure, a reflecting sheet and a circuit board which are sequentially arranged, wherein light-transmitting characters, figures or functional patterns are printed on the touch panel, the light-guiding module is a plurality of independent light-guiding sheets, microstructure light-emitting points are arranged on the back surface of each light-guiding sheet, and the circuit board is provided with a plurality of light-emitting components.

Further, the touch panel is printed with required key characters, numbers or patterns and is arranged on the uppermost layer, and the touch panel is made of a light-transmitting material.

Further, the light-emitting shading sheet is arranged above the light guide sheet, and the light-emitting shading sheet is provided with a light-transmitting opening.

Further, each light guide module is an independent light guide sheet, and the back surface is provided with micro-structure lattice points.
