A light-emitting package structure includes a light transmissive adhesive layer, a substrate, and at least one light-emitting diode chip. The light transmissive adhesive layer includes a first surface and a second surface facing away from the first surface. The substrate is on the first surface of the light transmissive adhesive layer. The light-emitting diode chip is on the second surface of the light transmissive adhesive layer. The light transmissive adhesive layer has a first portion and a second portion on the second surface, the first portion surrounds the second portion, a vertical projection area of the second portion on the substrate at least entirely covers a vertical projection area of the light-emitting diode chip on the substrate, and a thickness of the second portion is smaller than or equal to a thickness of the first portion.

Light-emitting package structure

A wavelength-converting film and a light emitting device and a display device using the same are disclosed. The wavelength converting film comprises a fluoride phosphor powder with a Mnas an activator, wherein the fluoride phosphor powder with the Mnas the activator comprises a sheet-like crystal and has a chemical formula of A[MF]:Mn, wherein A is Li, Na, K, Rb, Cs, NH, or a combination thereof, and M is Ge, Si, Sn, Ti, Zr, or a combination thereof.

Wavelength-converting film and light emitting device and display device using the same

A fluoride phosphor including a sheet-like crystal and a manufacturing method and an application therefore are disclosed. The fluoride phosphor has a chemical formula A[MF]:Mn, with Mnas an activator. The A is Li, Na, K, Rb, Cs, NH4 or a combination thereof. The M is Ge, Si, Sn, Ti, Zr or a combination thereof. The sheet-like crystal has a thickness d. A crystal flat surface of the sheet-like crystal has a maximum length a. The maximum length a is defined as a distance between two end points on an edge of the crystal flat surface and farthest from each other. 8&#x2264;a/d&#x2264;35.

Fluoride phosphor including sheet-like crystal and manufacturing method and application thereof

The present disclosure provides a light emitting structure including a blue light source, a first fluorescent material layer and a second fluorescent material layer.
