Assignee:

Qualcomm Mems Technologies, Inc. - San Diego IL

International Classification:

G09G 3/34
G02B 26/00

US Classification:

345 84, 345 55, 345 85, 359290, 359291, 385146

Abstract:

A display device including a plurality of optical modulators and a plurality of filter elements on a reflective side of the plurality of optical modulators is provided. The plurality of optical modulators includes a first set of optical modulators and a second set of optical modulators. Each optical modulator of the plurality of optical modulators is configured to be selectively switched among at least a first state, a second state, and a third state. Each state has a different spectral reflectance. The plurality of filter elements includes a first set of filter elements corresponding to the first set of optical modulators and a second set of filter elements corresponding to the second set of optical modulators. The first set of filter elements has a different spectral transmittance than the second set of filter elements.

International Classification:

G09G 5/10

US Classification:

345690, 345596

Abstract:

Displays, and methods of displaying images with the displays, which have quantized display characteristics for each of the pixels are disclosed. The displays and methods relate to both spatially and temporally dithering images so that the effective resolution of the display is higher than the result of the native spatial and intensity resolutions of the display, defined by pixel size, pitch, and number of quantization levels of each of the pixels.

Appl. No.:

16/393679

Inventors:

Alan K Lewis - Bellingham WA, US

International Classification:

A63C 17/01
A63C 17/14

Abstract:

According to an embodiment, a wheeled vehicle is provided, which includes a frame supporting a rear wheel, a rider's deck, and a steering post lying parallel to a longitudinal axis of the vehicle. A front axle is coupled to the frame and configure to rotate about the steering post while remaining perpendicular to the longitudinal axis. Axle stubs are coupled to respective ends of the axle so as to be pivotable relative to the axle, and front wheels are rotatably coupled to the axle stubs. A steering mechanism is configured to permit a rider to steer the vehicle by leaning on the rider's deck.
