Abstract: This disclosure provides devices, apparatuses and methods of providing an optical filter with quantum dot films for converting a first wavelength of light to a second wavelength of light. The optical filter includes a plurality of high refractive index layers and a plurality of low refractive index layers alternatingly disposed between the high refractive index layers. Quantum dots are dispersed in either the high refractive index layers or the low refractive index layers. In some implementations, the quantum dots are capable of absorbing blue light and emitting green light. Thus, the optical filter can be part of a red-green-blue lighting device that includes a first blue LED optically coupled with the optical filter to produce green light, a red LED and a second blue LED.

Abstract: Systems, methods and methods of manufacture for, among other things, a MEMS display that has a substrate with a first and a second array of apertures. The first and second arrays are, typically, formed on the substrate so that the arrays are adjacent and define a field boundary line that may extend between the two arrays and along a width of the substrate. In at least one array, the apertures that are proximate the field boundary line are placed at locations on the substrate to reduce differences in luminance between one portion of the display and another portion of the display.

Abstract: In one innovative aspect of the disclosure, a method includes patterning a first region and a first portion of a second region of a substrate using a first reticle. The method also includes patterning the second region and a first portion of the first region using a second reticle. The method additionally includes forming a first array of first patterned elements based on the patterning by the first reticle, and forming a second array of second patterned elements based on the patterning by the second reticle. In some implementations, each of the first and the second arrays are incomplete in each of the first portions. However, the first patterned elements in the first portion of the second region are complementary to the second patterned elements in the first portion of the second region. Similarly, the first patterned elements in the first portion of the first region are complementary to the second patterned elements in the first portion of the first region. In some such implementations, the combination of the first array and the second array form a complete array of patterned elements.

Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In one image formation process, the controller can determine a number of subframes to be displayed for a subfield based on a temperature of a display apparatus. In some implementations, the controller can determine dithering parameters based on the determined number of subframes, and perform dithering on pixel intensity values based on the determined dithering parameters. In some implementations, a vector error diffusion technique can be utilized for performing dithering. In some implementations the controller can determine drive voltages for light modulators and drive currents for light sources used for displaying the subframes, based on the temperature of the display apparatus.

Abstract: This disclosure provides systems, methods and apparatus for dissipating charge buildup within a display element with a conductive layer. The conductive layer is maintained in electrical contact with a fluid within the display element. The fluid, in turn, remains in contact with light modulators within the display elements. Any charge buildup that may be caused by the filling of the fluid during fabrication of the display device, or during operation of the light modulators can be dissipated by the conductive layer. Thus, by dissipating the charge buildup, the conductive layer reduces or eliminates electrostatic forces due to the charge buildup that may affect the operability of the light modulators. The display can include conductive spacers in an active display region of the display and a spacer-free region that allows the substrates to deform while retaining an electrical connection between the conductive layer and the spacers in the active display region.
