Abstract: Novel backlighting units (BLU) for use with LCD panel are disclosed. Such BLUs have direct lighting configuration utilizing blue LED as light source and have quantum dots (QDs) integrated into the architecture of the BLU thus forming thin BLUs that efficiently convert the blue source light into white light while achieving enhanced uniformity in brightness of the white light.

Abstract: A backlight includes a substrate, a plurality of light sources, a reflective layer, a light guide plate, a pattern of light extractors, a plurality of patterned reflectors, and a diffusive layer. The plurality of light sources are proximate the substrate. The reflective layer is on the substrate. The light guide plate is proximate the plurality of light sources. The pattern of light extractors is on the light guide plate. The plurality of patterned reflectors are on the light guide plate. Each patterned reflector is aligned with a corresponding light source. The diffusive layer is on the light guide plate.

Abstract: A display system with local brightening function, the system including a display unit to display an image to a user; a sensor to detect an event, including an interaction with the display system by the user or an ambient lighting condition; and a control unit to determine a specified region of the display unit corresponding to a targeted area of the event. The control unit can change a spatial luminance of the display system based on the event, where the display system switches from a first operation mode to a second operation mode when the event is detected and, in the second operation mode, a luminance of the specified region relative to other regions of the display unit is different than a luminance of the specified region relative to the one or more other regions in the first operation mode.

Abstract: Methods, systems, devices, and apparatuses are described. A variable diffuser pattern (VDP) may be applied to a substrate and configured to diffuse light from a light source (e.g., a light emitting diode (LED)), where the diffused light may have luminance uniformity and color uniformity measured at various distances from the light source. The VDP may include two or more different materials (e.g., different nanoparticle inks), and each material may have unique spectral reflectance and transmittance properties. For example, a first material may produce relatively more backscatter in red light wavelengths (e.g., as compared to blue and green light wavelengths), and a second material may produce relatively increased backscatter in blue light wavelengths (e.g., as compared to red and green light wavelengths). The VDP including the first and the second material may provide controlled scattering of light from the light source, resulting in uniform luminance and color of the scattered light.
