  • Patent number: 10107461
    Abstract: A light-emitting display has a circuit board, a spacer, a phosphor film, and a housing. The circuit board is provided with at least one light source. The spacer is disposed on a top surface of the circuit board. The spacer has a through hole which runs through the spacer from top to bottom and corresponds to the at least one light source and the phosphor film respectively. The housing has a reflecting portion and an accommodating space below the reflecting portion. The reflecting portion is located over the phosphor film. The accommodating space accommodates the circuit board, the spacer, and the phosphor film. The present disclosure also provides a method for forming the light-emitting display.
