Abstract: Aspects of the invention include a display device including a liquid crystal display (LCD) panel comprising a plurality of blue color filters, a plurality of green color filters, and a plurality of red color filters; and a light source configured to provide light to the LCD panel. The light has a spectrum with a blue component, a green component and a red component. In one embodiment, the blue component has at least one peak wavelength in between 465 nm to 495 nm. In another embodiment, the blue component has an intensity being broadly distributed over a wavelength range of 430 nm to 495 nm. The plurality of green color filters has a transmission cut off wavelength being 480 nm or greater than 480 nm. The plurality of blue color filters has a transmission cut off wavelength being no greater than 500 nm.

Abstract: A package body for a semiconductor device includes a lead frame, an insulating package, and a reflective coating layer. The lead frame has a first electrode and a second electrode separated from each other. The insulating package provides a housing structure and forming a package cavity therein. The package cavity has a reflective side surface formed by the insulating package. The reflective coating layer partially covers the first electrode and the second electrode and forms a reflective bottom surface of the package cavity. Each of the first electrode and the second electrode may have an angled cut. The insulating package may be made of a binder-filler composite containing white pigments. The package body may be an all diffusive integrated reflecting surfaces (AR-IRS) package body, and may be used in an encapsulant-free semiconductor package.

Abstract: The present disclosure includes an optical component including one or more microstructures configured to diffuse light incident thereto from within the optical component. The microstructures are provided at least on a light input surface of the optical component provided in a bottom cavity of its body.
