20080259634 | DOUBLE-SIDED TURNING FILM - A backlight device for a display comprising (1) a side-lit light source, (2) a light guide plate and (3) a turning film comprising a light entry and a light exit surface comprising lenticular elements on the exit surface and prismatic structures on the entry surface, wherein the average values of the parameters of the features and the thickness of the film are selected to provide a peak output angle of ±10° from normal to the light exit surface of the light guide plate and an optical gain of at least 1.25. Also disclosed are methods of making the turning film and a display incorporating the backlight. | 10-23-2008 |
20080297537 | DEVICES AND METHODS FOR SYNCHRONIZED ILLUMINATION - Disclosed is a display of a particular size that may be perceived as larger than the particular size as a result of light emitted by one or more light guides adjacent the perimeter of the display. The display may also be perceived as brighter. In particular, the display is configured to output a changing image. A light guide is disposed adjacent at least a portion of the perimeter of the display and coupled to a multicolor LED. A controller of the electronic device is configured to analyze the changing image to determine the color content. The multicolor LED is driven to emit light according to the color content of the changing image. The light guide is configured to couple light from the LED in a direction parallel to the display viewing surface, and to couple light out of the light guide in a direction away from the display viewing surface. | 12-04-2008 |

20100097549 | Reflective Morphable Display Device and method of Feature Activation - 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 (λ/4) retardation film layer. Linearly polarized light emerging from the front surface of a display device is circularly polarized by the λ/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 λ/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. | 04-22-2010 |
20100103198 | METHOD OF CORRECTING EMISSIVE DISPLAY BURN-IN - A method and apparatus are provided for correcting burn-in in a flat screen display. The method includes the steps of determining a maximum cumulative luminance of each pixel ( | 04-29-2010 |
20100156805 | Touch Screen Device and Methods Thereof Configured for a Plurality of Resolutions - Disclosed is a touch screen and a method of touch screen having a first plurality of sensor segments coupled to first scan lines and a second plurality of sensor segments being subsections of one of the first plurality of sensor segments, the second plurality of sensor segments including second scan lines that are bundled by a multiplexer configured to aggregate output of the second plurality of sensor segments into a single transmission channel. The individual output of the multiplexed sensor segments subsections can be either combined into a single signal for processing during a normal scan, or their individual output can be processed individually for higher resolution. Using two scans, the first a normal scan, and the second a higher resolution scan, the disclosed touch screen and methods zoom in on the proximity of the touched area and scans with a higher resolution the proximity only where it is needed. | 06-24-2010 |
