Publication number: 20150301563Abstract: An electronic device may have a housing in which a display is mounted. A gasket may be mounted in a groove between the display and housing. The gasket may contain an embedded stiffener. Corner brackets may be installed in the corners of the housing. The housing may have inner and outer concentric ribs. Recesses in the housing may be configured to receive the corner brackets. The recesses may be formed between the inner and outer concentric ribs. Gap filling structures such as a foam layer may be interposed between a rear housing wall and a display backlight unit. Display color variations may be corrected by using a backlight unit having an array of light-emitting diodes of different colors. An electrostatic discharge protection layer may be grounded to a housing using conductive tape. Black edge coatings and adhesive-based structures may block stray light. Camera window regions may be supported using adhesive.Type: ApplicationFiled: June 29, 2015Publication date: October 22, 2015Inventors: Dinesh C. Mathew, Bryan W. Posner, Keith J. Hendren, Adam T.

Publication number: 20150248033Abstract: An electronic device may be provided with a display mounted in a housing. The display may include a liquid crystal display module and a reflective polarizer having an in-plane optical axis. The display may also include a backlight unit that includes a light source, a light guide element, and a reflector film coupled to a backside of the light guide element. The display may also include a light retardation layer such as a quarter wave film. The quarter wave film may be arranged between the reflective polarizer and the reflector film of the backlight unit. Partially polarized light that is output from a front side of the light guide element may have a first component parallel to the in-plane optical axis and a second component perpendicular to the in-plane optical axis of the reflective polarizer. The second component may be reflected from the reflective polarizer.Type: ApplicationFiled: April 13, 2015Publication date: September 3, 2015Inventors: Xinyu Zhu, Jun Qi, Meizi Jiao, Nicholas G.

Patent number: 9075199Abstract: An electronic device may have a display. Inactive portions of the display may be masked using an opaque masking layer. An opening may be provided in the masking layer. A camera may receive light through the opening in the opaque masking layer. The display may include upper and lower polarizers, a color filter layer, and a thin-film transistor layer. The upper polarizer may have an unpolarized window aligned with the opening in the opaque masking layer for the camera, a logo, or another internal structure. The unpolarized window may be formed from openings in polarizer layers such as a polyvinyl alcohol layer and optical retarder layers. The openings may pass through all or less than all of the polarizer layers. The openings may be filled with transparent filler material. The polarizer may include a try-acetyl cellulose layer that continuously covers the opening in other polarizer layers.Type: GrantFiled: October 30, 2012Date of Patent: July 7, 2015Assignee: Apple Inc.Inventors: Meizi Jiao, Jun Qi, Victor H.

Publication number: 20130215136Abstract: The present disclosure relates generally to a liquid crystal display (LCD) that has a large color gamut. In certain embodiments, the large color gamut in the LCD may be obtained by adding a spectrum-filter into different layers of the LCD. The spectrum-filter may be designed to filter a portion of a color band from a light emitted from one or more light emitting diodes (LEDs) in the LED thereby increasing the color gamut on the LCD.Type: ApplicationFiled: February 20, 2012Publication date: August 22, 2013Applicant: APPLE INC.Inventors: Meizi Jiao, Jun Qi, Victor Hao-En Yin, Wei Chen

Publication number: 20130044120Abstract: Systems, methods, and devices are provided for an electronic display with thermally compensated pixels. Such an electronic display may have an array of pixels, at least some of which may be thermally compensated pixels that exhibit reduced color shift over a 20° C. change in temperature. These thermally compensated pixels may have numbers of pixel electrode fingers, pixel electrode widths and spacings, cell gap depths, and/or pixel edge distances that cause the array of pixels to exhibit a reduced color shift than otherwise (e.g., a color shift of less than delta u?v? of about 0.0092 from a starting white point) when the temperature of the electronic display changes from about 30° C. to about 50° C.Type: ApplicationFiled: August 19, 2011Publication date: February 21, 2013Applicant: APPLE INC.Inventors: Zhibing Ge, Meizi Jiao, Jun Qi, Cheng Chen, Young Bae Park, Shih Chang Chang, Victor Hao-En Yin, John Z.
