A display system includes visible light emitting first devices configured to emit a first light having at least a first visible wavelength; ultraviolet light emitting second devices configured to emit a second light having at least a second ultraviolet wavelength; a display panel disposed on the first and second devices; and a reflective polarizer disposed between the display panel and the first and second devices, such that the reflective polarizer has, for the visible wavelength, an average optical reflectance of greater than about 50% when an incident light is polarized along an in-plane first direction and an average optical transmittance of greater than about 50% when the incident light is polarized along an in-plane orthogonal second direction; and an optical transmission of greater than about 30% for the at least the second wavelength and for at least one of the first and second polarization states.

Display systems using IR and UV transparent optical films

Optical stacks are described that include a reflective polarizer disposed between an infrared reflector and an infrared absorber.

An organic light emitting diode (OLED) display is described, and includes a pixelated OLED display panel including N a plurality of pixels, each pixel including a plurality of subpixels, and each subpixel including a plurality of OLED layers. A hybrid color correction component is disposed on the pixelated OLED display panel, and the hybrid color-correction component includes a nanostructured interface and an angular transformation layer, the angular transformation layer is disposed between the nanostructured interface and the pixelated OLED display panel.

Organic light emitting diode display with color-correction component

A testing device for wafer level testing of IC circuits is disclosed. An upper and lower pin () are configured to slide relatively to each other and are held in electrically biased contact by an elastomer (). To prevent rotation of the pins in the pin guide, a walled recess in the bottom of the pin guide engages flanges on the pins. In another embodiment, the pin guide maintains rotational alignment by being fitted around the pin profile or having projections abutting the pin. The pin guide () is maintained in alignment with the retainerby establishing a registration corner () and driving the guide into the corner by elastomers in at least one diagonally opposite corner.

Wafer level integrated circuit probe array and method of construction

A testing device for wafer level testing of IC circuits is disclosed. An upper and lower pin () are configured to slide relatively to each other and are held in electrically biased contact by an elastomer (). The elastomer is precompressed from its natural rest state between a top () plate and a bottom (). Pre compression improves the resilient response of the pins. The pin crowns () are maintained relatively coplanar by the engagement of at least one flange (-) against an up-stop surfaceof plate, thereby insuring coplanarity of the crowns. The pin guide () is maintained in alignment with the retainerby establishing a registration corner () and driving the guide into the corner by elastomers in at least one diagonally opposite corner.

Data storage replica disks having a surface relief pattern with replica lands and replica grooves are provided.

Replica disk for data storage

A data storage master disk and method of making a data storage master disk. The data storage disk master is for use in a data storage disk replication process. The data storage disk molding processes produces replica disks having a surface relief pattern with replica lands and replica grooves. The method includes providing a master substrate. The master substrate is at least partially covered with a layer of photosensitive material. A surface relief pattern having master lands and master grooves is recorded in the data storage disk master, including the steps of exposing and developing the photosensitive material is controlled to form master grooves extending down to a substrate interface between the master substrate and the layer of photosensitive material, such that the width of the master grooves at the substrate interface corresponds to a desired width of the replica lands.

Reverse optical mastering for data storage disk replicas

The disclosure is directed to optical disks with a microstructured surface formed on a surface of the optical disk. The microstructured surface may be created to promote the adhesion and prevent the migration of a print material applied to the surface of the optical disk. The microstructured surface may be in the form of a plurality of wells or a plurality of discontinuous raised features in the surface. By forming a microstructured surface on the surface of the disk, the optical disk may not need an additional coating to receive the print material while also retaining the print material at a precise location on the surface. In addition, a plurality of standoff features may be formed in an outer surface of the optical disk to help prevent damage to the surface of the optical disk.
