Abstract: A display apparatus includes a backlight and an aperture layer that is positioned in front of the backlight and defines a plurality of apertures. The display apparatus also includes a microelectromechanical system (MEMS) light modulator configured to modulate light emitted by the backlight passing through the apertures to form an image on the display apparatus. The MEMS light modulator includes a shutter (1202) that has a light blocking portion having an aperture layer-facing surface and a front-facing surface and at least one depression (1207) formed in the light blocking portion. The width of the at least one depression accounts for at least 50% but less than 100% of a distance separating two edges of the shutter. In other embodiments the shutter perimeter surface is angled. Light leakage is mitigated.

Abstract: This, disclosure provides systems, methods and apparatus for improving the angular light distribution of a display apparatus. Smaller shutter-based display apparatus that modulate light passing through at least two apertures in an aperture or light blocking layer can provide similar viewing angle characteristics as larger shutter-based modulators by disproportionately reducing the width of a subset of the at least two apertures in relation to the remainder of the apertures. As the width of such apertures is one of the primary determinants of viewing angle, allowing a greater percentage of the light throughput of a shutter assembly to pass through wider apertures helps maintain a wider viewing angle for the display.

Abstract: A display for generating three-dimensional images includes an array of light modulators for selectively obstructing a respective apertures and a controller. The controller can control a set of light modulators in the array to form, at a first time, a first eye image corresponding to input data by causing the light modulators to be driven into a first set of positions determined based on the input data. The first eye image includes an angular distribution of light weighted towards a first side of the display. The controller can also control the same set of light modulators to form, at a second time, a second eye image corresponding to input data by causing the light modulators to be driven into a second set of positions determined based on the input data. The second eye image includes an angular distribution of light weighted towards an opposite side of the display.

Abstract: This disclosure provides systems, methods, and apparatus for a MEMS display incorporating integrated sidewall reflectors. The display can include a light blocking component suspended over a substrate. The light blocking component can include an aperture in its surface that is parallel to the substrate. The display can include one or more sidewall reflectors positioned within the aperture. The one or more sidewall reflectors can be arranged at least partially normal to the surface of the light blocking component. Light that is directed through the aperture can be reflected off of the sidewall reflectors to escape from the display at a higher angle than would otherwise be possible.

Abstract: Systems, apparatuses and methods are provided for increasing the aperture ratio of a display by increasing the total travel distance of respective light modulating bodies in a display while maintaining fast switching speeds. Increasing the total travel distance allows for a larger aperture ratio in a display, which provides greater power savings and increased display brightness. The total travel distance of a light modulating body includes the distance the body travels from an open position to a closed position, and vice-versa. In one example, the travel distance of a light modulating body (e.g., any of the light modulators as described above) is asymmetric: from a neutral position, the body travels a greater distance in a first direction than in a second direction.

Abstract: This disclosure provides devices, apparatuses and methods of providing an optical filter 630a 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 610 and a plurality of low refractive index layers 620 alternatingly disposed between the high refractive index layers. Quantum dots 650 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 605 and emitting green light 615. 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: 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: 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.
