A light emitting module including the light uniformization structure is also disclosed.

Light uniformization structure and light emitting module

A new light emitting device is disclosed, including a polarizing surface layer, a light emitting layer which emits light at a wavelength, and a light transformation layer disposed between the light emitting layer and the reflective layer, wherein the light emitting layer is disposed between the reflective layer and the polarizing surface layer, and an optical thickness between the light emitting layer and the reflective layer is less than a value of five times of a quarter of the wavelength.

Light emitting devices

A method for forming a pixel of an LED light source is provided. The method includes following steps: forming a first layer on a substrate; forming a second layer and a first light-emitting active layer on the first layer; exposing a portion of an upper surface of the first layer; forming a third layer on the substrate; forming a fourth layer and a second light-emitting active layer on the third layer; exposing a portion of an upper surface of the third layer; and forming a first electrode on the exposed upper surface of the first layer, a second electrode on a portion of an upper surface of the second layer, a third electrode on the exposed upper surface of the third layer, and a fourth electrode a portion of an upper surface of the fourth layer. The first light-emitting active layer and the second light-emitting active layer emit different colors of light.

Light emitting module having LED pixels and method of forming the same

A microchip matrix light source module includes at least two LEDs formed on a surface of a substrate. The light source further includes a light reflector formed on a surface upon which the LEDs are formed and interposed between the LEDs and configured to reflect and thereby redirect laterally emitted light from the two LEDs. The light reflector may include an inner body. The body may be covered, in part or in whole, with a light reflecting layer such as a metal layer. The body of the light reflector may include a layer corresponding to a layer in one of the two LEDs.
