The utility model adopts the above technical scheme, compare with prior art, beneficial effect is: through set up printing opacity portion and black printing opacity portion on silica gel keypad, the leaded light and the light seal design of silica gel button have been realized, through set up black anti-dazzling screen on the transparent leaded light layer of metal dome and leaded light membrane body structure, make transparent leaded light layer realize mutually independent leaded light region through black anti-dazzling screen, the leaded light of metal dome and leaded light membrane body structure and the design of sealing light have been realized, the light seal problem between each independent bright lamp region has effectively been solved, the remote controller consumption is reduced, the battery life is prolonged, user experience has been improved.

Furthermore, the black light shielding layer, the transparent light guide layer and the thin film layer pasted with the metal dome are connected through glue.

In order to separate the light emitting areas independently, the black shading layer and the black shading strips are made of black PET shading paper.

In order to greatly reduce the risk of light leakage and crosstalk, a plurality of light holes are formed in the black shading layer; the light emitting hole is arranged right below the key.

In order to realize that each light guide region is independent, the transparent light guide layer is transparent PC light guide film, and is separated by black PET shading strip.

Furthermore, the film layer adhered with the metal dome sheet is a PET film.

In order to separate the light emitting areas, a bone site is provided inside the housing.

Furthermore, the light transmission part and the black light-tight part on the silica gel key panel are integrally formed by adopting a hot press forming process.
