Abstract: A package includes a substrate, a first light-emitting unit, a second light-emitting unit, a light-transmitting layer, and a light-absorbing layer. The substrate has a first surface and an upper conductive layer on the first surface. The first light-emitting unit and the second light-emitting unit are disposed on the upper conductive layer. The first light-emitting unit has a first light-emitting surface and a first side wall. The second light-emitting unit has a second light-emitting surface and a second side wall. The light-transmitting layer is disposed on the first surface and covers the upper conductive layer, the first light-emitting unit, and the second light-emitting unit. The light-absorbing layer is disposed between the substrate and the light-transmitting layer, covers the upper conductive layer, the first side wall, and the second side wall, and exposes the first light-emitting surface and the second light-emitting surface.

Abstract: A backlight module is provided. The backlight module includes a substrate having a substrate surface, a conductive layer disposed on the substrate surface, a plurality of LED chips disposed on and electrically connected to the conductive layer, a light-permeable layer having a light-permeable surface away from the substrate surface, and a pattern layer disposed on the light-permeable surface and having a plurality of first patterns corresponding to and respectively located above the plurality of LED chips. Wherein, each first pattern has a maximum width. A maximum width of one first pattern satisfies the following formula: WP?2n(TE?TL)(1?1/n2)1/2+WL; wherein WP is the maximum width of one first pattern, n is a refractivity of the light-permeable layer, TE is a thickness of the light-permeable layer, TL is a thickness of the LED chip, WL is a maximum width of LED chip corresponding to the first pattern.
