A multi-layer display system for displaying 3D images with reduced saccadic breakup includes a plurality of display screens arranged in a substantially parallel and overlapping manner, and a processing system. The processing system is configured to minimize or prevent saccadic breakup of displayed images by detecting head and/or eye movement of a viewer, and accordingly controlling color saturation of display fields when movement of head and/or eye is detected.

An illustrative example embodiment of a display includes a cover, a plurality of display panels that collectively establish a display area, and a polarizer between the display panels and the cover. The polarizer is coextensive with the entire display area.

In-vehicle display

An illustrative example assembly includes a display having a first side for displaying at least one image and a second side facing opposite the first side. The display includes a first portion having a first plurality of layers between the first side and the second side. The display includes a second portion having a second plurality of layers between the first side and the second side. The second plurality of layers includes at least one additional layer more than the first plurality of layers. A camera is situated near the second side of the display with a field of view of the camera at least partially aligned with the first portion of the display.

Vehicle display including a camera

A multi-layered display (MLD) system having improved reliability for vehicular and other applications, is described. In one example, the MLD system detects a fault associated with a first display screen of the MLD, selects one of the display screens other than the first display screen as a backup display screen, combines an image generated for displaying on the first display screen and an image generated for displaying on the selected backup display screen to form a combined image, and displays the combined image on the selected backup display screen.

Content redirection in a multi-layered display system

A multi-display system (e.g., a display including multiple display panels) includes at least first and second displays (e.g., display panels or display layers) arranged substantially parallel to each other in order to display three-dimensional (3D) features to a viewer(s). The first and second displays have different color filter patterns, respectively, as viewed from a point of view of a viewer of the display device, in order to reduce moir&#xe9; interference.

A multi-layered display including an upper display screen, and a lower display screen arranged so as to at least partially overlap with the upper display screen is described. An antiglare layer is disposed on the upper display screen. The antiglare layer includes a diffraction pattern configured to blur ambient reflections without substantially affecting transmitted light. The diffraction pattern may have a quarter wavelength thickness. Method for forming the multi-layered display is also provided.

A physical layout for a circuit using amorphous metal non-linear resistors as active devices for an in-plane switching liquid crystal display sub-pixel is provided. The lower interconnect of the two amorphous metal non-linear resistors and the lower electrode of the storage capacitor may be concurrently deposited and patterned. The area of the storage capacitor is defined by the overlap of the data signal inter-connect and the storage capacitor lower electrode, which is easily modified through the size of the lower electrode and/or the size of the data signal interconnect where it overlaps the lower electrode and does not degrade the aperture ratio of the pixel. Two embodiments of sub-pixel circuits are described. One, which employs a select line bridge, enables the use of full dot inversion of the image data. The second only allows row inversion of the image data.

An interactive input system comprises a display panel; a first illumination source providing illumination across an outer surface of the display panel such that when a pointer is brought into proximity with the outer surface, the pointer reflects illumination from the first illumination source through the display panel; at least one imaging device having a field of view aimed at an opposite outer surface of the display panel, the at least one imaging device capturing images including illumination reflected by the pointer through the display panel; and processing structure in communication with the at least one imaging device, said processing structure processing the captured images to determine a location of the pointer relative to the outer surface.

Interactive input system and method

A coordinate detection system can comprise a display screen, a touch surface corresponding the top of the display screen or a material positioned above the screen and defining a touch area, at least one camera outside the touch area and configured to capture an image of space above the touch surface, and a processor executing program code to identify whether an object interferes with the light from the light source projected through the touch surface based on the image captured by the at least one camera. The processor can be configured to carry out a calibration routine utilizing a single touch point in order to determine a plane corresponding to the touch surface by using mirror images of the features adjacent the touch surface, images of the features, and/or based on the touch point and a normal to the reflective plane defined by an image of the object and its mirror image.

Touch screen signal processing with single-point calibration

A touch screen which uses light sources at one or more edges of the screen which directs light across the surface of the screen and at least two cameras having electronic outputs located at the periphery of the screen to receive light from said light sources. A processor receives the outputs of said cameras and employs triangulation techniques to determine the location of an object proximate to said screen. Detecting the presence of an object includes detecting at the cameras the presence or absence of direct light due to the object, using a screen surface as a mirror and detecting at the cameras the presence or absence of reflected light due to an object. The light sources may be modulated to provide a frequency band in the output of the cameras.

Touch screen signal processing

A coordinate detection system can comprise a display screen, a touch surface corresponding the top of the display screen or a material positioned above the screen and defining a touch area, at least one camera outside the touch area and configured to capture an image of space above the touch surface, an illumination system comprising a light source, the illumination system configured to project light from the light source through the touch surface, and a processor executing program code to identify whether an object interferes with the light from the light source projected through the touch surface based on the image captured by the at least one camera. Light can be directed upward by sources positioned behind the screen, by sources positioned behind the screen that direct light into a backlight assembly that directs the light upward, and/or by a forward optical assembly in front of the screen that directs the light upward.

In an optical touch display system, light from a primary source can be retroreflected to a detector in the absence of an object in the detection area. When an object is present, its position can be triangulated based on the direction of its shadows at the detectors. Accuracy can be improved with a secondary light source positioned off-axis from the primary light sources so that minimal light from the secondary source is retroreflected to the detectors. Instead, when an object is present, light from the secondary source may be reflected directly from the object. Each detector signal representing light due to the primary light source can be corrected to remove light reflected directly from the object based on identifying and removing a signal component representing light from the secondary light source. In some embodiments, this is facilitated by phasing the primary and secondary light sources.

Optical touchscreen with improved illumination

A low profile touch display can be provided, namely one including an optical detection system with the bulk of the electronics and optics positioned partially or completely below the detecting plane surface. The light source and optical detection system components can be configured so that the exit and entry apertures for light being directed to and/or received from the detection plane are the only members above the touch surface. For instance, a reflective or refractive member at the edge of the touch surface can direct light to detection optics and/or from illumination sources via a pinhole aperture, with the light moving between the detection optics and illumination sources in one or more detection planes above the touch surface. Consequently, the touch screen can have a thin cross section that is more suitable for devices such as mobile phones, PDAs, and other portable computing devices for which minimal device thickness is a priority.
