Abstract:
A flat panel display having a single back glass substrate and a single color filter passive plate divided into multiple, electrically isolated, separately addressable, functional sections having no visible seam between sections.
Abstract:
Optical systems are described that include a switchable diffuser, a display panel, a lighting component and a diffuser controller. The diffuser controller is configured to switch the state of the switchable diffuser when the diffuser controller determines that the diffuser state is to be changed. The diffuser controller may be configured to vary an output level of the display panel in association with a change in state of the switchable diffuser. The optical system may also include a switching device which may be separable from the display panel.
Abstract:
There is provided amethod of driving a display of active matrix-type. The matrix 100 includes addressable pixels associated with lines L -L M and columns of the matrix. The method comprises writing image data to the matrix utilizing a line timing LT determined by a preselected base frame rate BR and the number of lines M of the matrix, determining an extended frame rate N-frame for addressing all pixels of the matrix, and providing a preselected intermittent refresh IR by distributing the writing of image data to all pixels within a time period defined by the extended frame rate N-frame.

Abstract:
An apparatus for conserving power in information devices with dual functions. A single display panel (200) is logically split into two sub-panels (202, 204). Each subpanel can be powered up or down separately as is required by the function of the device. The display panel (200) has a plurality of improved segment drivers (120, 122) which are provided power signals enabling the set of segment drivers corresponding to a sub-panel to be separately powered. In systems with two separate display panels, each of the panels may be powered up or down by the use of similar improved segment drivers as necessary.
Abstract:
A method and apparatus for compensating crosstalk in liquid crystal displays (1 and 2) is disclosed which involves applying boost voltages (V5- and V0+) to the rows (40) and columns (38) of the display (1 and 2) in proportion to the number of ON pixels in a row (40) or column (38), the number of transitions between "ON-and-OFF" or "OFF-and-ON" in each column, and the position of the pixel (Px, y) ina row (40). "Boost" voltages (V5- and V0+) are applied to each row (40) as it is being actively scanned to provide horizontal crosstalk compensation, while "boost" voltages (V5- and V0+) are applied to each column (38) during the vertical retrace interval of the display sequence to provide vertical crosstalk compensation. In a preferred embodiment, the vertical crosstalk compensation is determined during the vertical retrace interval over several frames.
Abstract:
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for displaying information in various display regions within wearable display devices in a manner that enhances user experience and extends battery life. The wearable display devices may include a flexible display region and may be capable of operating in a wrinkled state. In some aspects, the wearable display devices may be capable of displaying images at different image qualities in the separate display regions. For example, in some implementations, wearable display devices include a first display region that has a higher pixel density than the second display region. In some aspects the wearable display devices may be configured to determine and/or select a display region in which specific image content is displayed. For example, text may be displayed region best suited to display text while video is displayed in region best suited to display video.
