Publication number: 20230010162Abstract: This document describes systems and directed at rejecting display leakage light in under-display sensors. In aspects, an ambient light sensor of an electronic device rejects leakage light originating from pixels in a display using a look-up table and an ambient light calculating formula. In implementations, the look-up table is developed based on a variety of operating conditions that the electronic device may experience, including variable refresh rates and display luminosities. The look-up table includes pre-calculated values of a leakage light ratio, for given operating conditions, that can be used to reject leakage light originating from displays by computing the ambient light calculating formula.Type: ApplicationFiled: September 15, 2022Publication date: January 12, 2023Applicant: Google LLCInventors: Sangmoo Choi, Mark Mienko

Patent number: 8373821Abstract: A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.Type: GrantFiled: June 7, 2010Date of Patent: February 12, 2013Assignee: QUALCOMM MEMS Technologies, Inc.Inventors: Jeffrey B. Sampsell, Russell W. Gruhlke, Mark Mienko, Gang Xu, Ion Bita

Patent number: 8107155Abstract: Embodiments include systems and methods for reducing visible artifacts such as Moiré, or interference, patterns, in displays. One embodiment includes a display device comprising a plurality of light modulators and a plurality of illumination elements configured to direct light to the light modulators. The directed light of the plurality of illumination elements collectively defines an nonuniformly varying pattern of light.Type: GrantFiled: October 6, 2006Date of Patent: January 31, 2012Assignee: Qualcomm MEMS Technologies, Inc.Inventors: Ion Bita, Gang Xu, Mark Mienko, Russell Wayne Gruhlke

Patent number: 7855827Abstract: An optical isolation structure is incorporated into a display between the display elements and the transparent substrate for the display elements. The optical isolation structure reflects light rays within the substrate that impact the structure at high angles relative to normal to the structure, thereby permitting the substrate to be used as an integrated light guide for distributing light over the display from a light source on the edge of the substrate. The optical isolation structure may include a single layer having an index of refraction less than the substrate or a plurality of thin-film interference layers.Type: GrantFiled: October 6, 2006Date of Patent: December 21, 2010Assignee: QUALCOMM MEMS Technologies, Inc.Inventors: Gang Xu, Alan Lewis, Brian Gally, Mark Mienko

Patent number: 7777954Abstract: Various embodiments of the invention include an interferometric optical modulator comprising a substrate layer and a light direction layer. Such an interferometric modulator may be integrated with a diffuser layer in a display device in a way that physically integrates the diffuser layer into the light direction layer in a way where the diff-user layer does not interact with light propagating within the light direction layer. As a result, most of the light propagating within the light direction layer does not penetrate into the diffuser which would inhibit performance of the display. In some embodiments, the interface between the diffuser layer and the light direction layer has a lower index of refraction than the light direction layer and the transparent substrate so that total internal reflection occurs at the interface.Type: GrantFiled: January 30, 2007Date of Patent: August 17, 2010Assignee: QUALCOMM MEMS Technologies, Inc.Inventors: Russell Wayne Gruhike, Mark Mienko, Gang Xu, Ion Bita

Publication number: 20090201301Abstract: An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure.Type: ApplicationFiled: December 23, 2008Publication date: August 13, 2009Applicant: QUALCOMM MEMS Technologies, Inc.Inventors: Mark Mienko, Gang Xu, Ion Bita, Lai Wang, Russell W.
