Patent number: 8692948Abstract: Displays such as liquid crystal displays may be used in electronic devices. During operation of a display, electrostatic charges on the surface of the display may give rise to electric fields. One or more electric field shielding layers may be provided in the display to prevent the electric fields from disrupting operation of the liquid crystals material in the display. The shielding layers may be formed at a location in the stack of layers that make up the display that is above the liquid crystal material of the display. Touch sensors and thin film transistors may be located below the shielding layer.Type: GrantFiled: May 21, 2010Date of Patent: April 8, 2014Assignee: Apple Inc.Inventors: Young-Bae Park, Ming Xu, Zhibing Ge, Cheng Chen, Shih Chang Chang, Shawn R.

Publication number: 20140036204Abstract: An electronic device may be provided with a display having backlight structures that include a light guide plate formed from a clear polymer film. The polymer film may have an edge into which light is emitted from an adjacent array of light-emitting diodes. The light emitting diodes may each include a semiconductor device that emits light. The semiconductor device in each diode may be mounted on lead frame structures and wirebonded to the lead frame structures with first and second wire bonds. To improve backlight homogeneity and thereby reduce the mixing distance for light in the light guide plate, the diodes may be spaced closely together using diode packages having end faces that are free of lead frame structures. Exposed lead frame structures for soldering the light-emitting diodes to a substrate may be formed under the light-emitting diodes and on rear surfaces of the light-emitting diodes.Type: ApplicationFiled: August 7, 2012Publication date: February 6, 2014Inventors: David A.

Publication number: 20140036203Abstract: Utilization of quantum dots in displays and the location of the quantum dot sheet within the stackup of the backlight can lead to issues such as non-uniform light mixing, non-uniform brightness, and off-axis changes in color. The mismatch between the isotropic nature of light emitted from the quantum dots and the light emitted directly from the light source can be alleviated by utilization of diffusers and prism sheets. The diffusers and prism sheets can be further utilized to change the angle of light such that it is directed upwards towards the top of the display for improved uniformity in brightness and enhanced performance. Placement of the diffuser sheets, prism sheets, and changes in the design of the components, such as the light guide path, can alleviate the issues by properly mixing the colors together in order to achieve a uniform distribution of colors in the display.Type: ApplicationFiled: October 31, 2012Publication date: February 6, 2014Applicant: Apple Inc.Inventors: Jean-Pierre S. GUILLOU, Shawn R. GETTEMY, David A. DOYLE

Publication number: 20140036536Abstract: A display that utilizes a microelectromechanical (MEMS) shutter module in order to accommodate a quantum dot sheet outside of the display backlight is provided. The MEMS shutter module can be placed either above or below the quantum dot sheet in order to more efficiently control the color at each individual pixel, when the color is being rendered from the isotropic emissions of the quantum dot sheet.Type: ApplicationFiled: October 31, 2012Publication date: February 6, 2014Applicant: Apple Inc.Inventors: Shawn R.

Patent number: 8558977Abstract: Electronic devices such as handheld electronic devices may have display modules. The display modules may be covered with a layer of protective cover glass. Peripheral portions of the cover glass may be coated with an opaque masking layer to block interior portions of the device from view. An opening in the opaque masking layer can be formed over an active portion of the display module. To facilitate alignment of the display module active area with the opening in the cover glass masking layer, the display module may be provided with alignment marks. The alignment marks may be formed in opposing corners at an end of the display module. The alignment marks may be formed from metal structures on one of the glass layers in the display module. An opaque masking layer that blocks stray backlight may have openings that are formed over the metal structures.Type: GrantFiled: September 11, 2009Date of Patent: October 15, 2013Assignee: Apple Inc.Inventors: Shawn R.

Patent number: 8482686Abstract: Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.Type: GrantFiled: February 7, 2013Date of Patent: July 9, 2013Assignee: Apple Inc.Inventors: Cheng Ho Yu, Ming Xu, Young Bae Park, Zhibing Ge, Daisuke Nozu, Cheng Chen, Abbas Jamshidi Roudbari, Shih Chang Chang, Shawn R.
