A display having a variably controlled backlight and/or driver is disclosed. The backlight includes a first light source that emits light within a first spectral power distribution and has a first radiant power output. A second light source emits light within a second spectral power distribution matched to an optical filter for producing a perceived chromaticity and luminosity matching the perceived display appearance without the optical filter.

Advanced LEP display mode, architectures and methodologies for display compensation

A display including a curved backlight and system for stray light control is disclosed. In embodiments, the curved backlight includes a curved substrate and an array of light sources disposed on the curved substrate, collimating optics, and a diffuser. The array of light sources includes a first group of light sources and a second group of light sources. The collimating optics are arranged to receive and collimate light only from the first group of light sources. The diffuser is arranged to receive and diffuse the collimated light from the collimating optics and light from the second group of light sources. The display further includes a liquid crystal layer arranged to receive light generated by the array of light sources and to display an image. The display further includes a controller configured to control the array of light sources such that at least some of the light sources emit light.

Curved backlight and system for stray light control

A touch screen or touch screen appliance includes built-in UV LEDs. The LEDs sterilize the touch screen at start-up, and periodically during operation. The LEDs may be disposed at the edges of the glass display such that the UV light is completely internally reflected within the glass display to prevent damage or strain to the user's eyes. Alternatively, the LEDs may be disposed behind the glass display, potentially also behind a UV fluorescing or phosphorescing layer to sterilize the glass from behind. Alternatively, the LEDs may be disposed in a layer in front of the glass display, or at angles around the perimeter of the glass display.

Sterilizing touch screen displays with ultraviolet light

The present disclosure is directed to a system for controlling light. The system may include a display. The display may include a light source configured to emit light having a specified spectral output. The system may also include a light filter applied to a substrate separate from the display. The light filter is configured to block light within the specified spectral output. The light filter is further configured to allow light outside of the specified spectral output to pass through the light filter.

Light control system

A piecewise light control layer includes a plurality of light control portions including a first light control portion and a second light control portion. The first light control portion is configured to restrict light having a first angular profile. The second light control portion is configured to restrict light having a second angular profile, wherein the first angular profile is different from the second angular profile.

Tailored stray light control for display applications

The present invention is a display assembly in which a backlight module generates light beams via a light source. The light source provides the light beams to a light guide of the backlight module. The light guide then provides the light beams to a display panel of the display assembly for illuminating the display panel. One or more optical elements are implemented between the light source and an insertion edge of the light guide for promoting improved light insertion efficiency for the display assembly. Further, the optical element(s) may promote improvements in color quality, luminance and/or uniformity of graphics or graphical depictions displayed by the display assembly.

System for improvement of light insertion into a light guide from light-emitting diodes (LEDs)

An light emitting diode (LED) assembly may include, but is not limited to: a printed circuit board comprising at least one aperture; a first LED mounted on a front surface of the printed circuit board; a second LED mounted on a rear surface of the printed circuit board; and a reflective surface configured to reflect light emitted by the second LED through the at least one aperture.

A light show device includes a light source configured to generate a light beam having a substantially constant diameter, a container having a substantially transparent portion, a plurality of mirrors, each mirror connectable or connected to the container rotatably about at least one axis, and a particulate source configured to create inside the container a substantial suspension of particulates, where the device is configured to allow a reflection of the light beam between at least a majority of the mirrors.

An inflatable electrical shocking weapon includes a hand portion, an inflatable extension configured to extend to an extension length upon inflation, and an electrical shocking device. The electrical shocking device includes a portable power source, a high-voltage generator connected to and configured to generate a high voltage from the portable power source, and at least two electrically conductive leads connected to the generator and configured to pass a current from the generator through a human at least when the human contacts the leads. The electrically conductive leads are connected to an end of the inflatable extension opposing the hand portion.

A safe air-pressure-launched toy rocket system includes an air-pressure-launched toy rocket, a high pressure reservoir, a manual air pump connected to the reservoir and configured to enable a user to pump air into the reservoir to a high pressure, a valve connected to the reservoir and configured, when opened, to release high pressure air stored in the high pressure reservoir to the toy rocket to launch the toy rocket, and two releases configured to be operable by different hands of the user. The releases are connected to the valve in a series-open configuration, where the valve is closed only when both of the releases are operated.

A foldable electric powered child riding vehicle includes a front module pivotally connected to a rear module. In a riding configuration, the modules are secured together in a stretched (i.e., deployed) position. An electric drive of the vehicle may be enabled only after the modules have been secured in the stretched position. In a storage/transportation configuration, the modules are disengaged and rotationally folded.

The present invention is a toy device that creates a visual illusion using a vibrating figure and strobe lighting. The user controls the strobe illumination frequency, as well as other potential aspects, to create different visual illusion effects.
