Patent number: 9122092Abstract: A user interface (200) for a portable electronic device (100) is configured to transition from a first state to a second state to present a plurality of mode-based user actuation targets to a user. The user interface (200) includes a segmented electro-optical device (407) configured to open and close shutters, thereby revealing and hiding the user actuation targets. The user interface includes a first polarizer (401) disposed above the segmented electro-optical device (407) and a colored reflective polarizer (405) disposed beneath the segmented electro-optical device. The colored reflective polarizer (405), which may include a colored dichroic polarizer (601) and a reflective polarizer (602), causes the user interface (200) to exhibit a predetermined color.Type: GrantFiled: June 22, 2007Date of Patent: September 1, 2015Assignee: Google Technology Holdings LLCInventors: Robert D.

Patent number: 8040475Abstract: Disclosed is reflective morphable display with multi-layered depth viewing, low power consumption and few components and a method of activating various features thereof. The disclosed display includes a bi-stable reflective cholesteric liquid display crystal (ChLCD) layered in combination with a display device such as an LCD and a quarter lambda (?/4) retardation film layer. Linearly polarized light emerging from the front surface of a display device is circularly polarized by the ?/4 layer before entering the ChLCD layer. In its reflective state, the ChLCD layer receiving a portion of the ambient light having the same handedness of the ChLCD is reflected in a mirror-like manner. Also in its reflective state, when it receives light that is circularly polarized by the ?/4 retardation film layer, the ChLCD layer acts as a shutter. A display device with depth viewing is provided as the ChLCD layer pixelated so it is configured to display font and/or other indicia.Type: GrantFiled: October 20, 2008Date of Patent: October 18, 2011Assignee: Motorola Mobility, Inc.Inventors: Tomohiro Ishikawa, Andrew N Cady, Robert D Polak, Kenneth A.

Publication number: 20080136794Abstract: Disclosed are devices for integrating photo sensors into sub-pixels of pixels of an array of pixels to substantially maintain the brightness of a touch screen display. In one embodiment, one or more photo sensors are distributed across two colored sub-pixels. Accordingly, the aperture ratios of the sub-pixels can be more substantially equal than the aperture ratios of the sub-pixels when a single sub-pixel includes a photo sensor. In another embodiment, one or more photo sensors are distributed across three sub-pixels. Accordingly, the aperture ratios of the sub-pixels may be substantially equal so that the light from each of the colors may mix in substantially equal amounts to generate white light. A white sub-pixel may be included with the sub-pixels of a pixel. A photo sensor may be integrated into the white sub-pixel. White light from combined colored light of sub-pixels can be further brightened by light from the white sub-pixel.Type: ApplicationFiled: December 7, 2006Publication date: June 12, 2008Applicant: MOTOROLA, INC.Inventors: TOMOHIRO ISHIKAWA, ROBERT D.
