The image display device includes a liquid crystal display device having a liquid crystal panel and a backlight and a backlight controller for allowing the backlight of the liquid crystal display device to be bright when environment light is bright and allowing the backlight to be dark when the environment light is dark such that light leak (minimum luminance) which is defined by an extinction ratio of liquid crystal will not grow more than a specified degree. The image display device enables di...

According to some embodiments, an apparatus, a system and a method are provided to reduce a backlit area of a display screen and resize an image to fit in the backlit area.

According to one embodiment, a display apparatus including a receiving unit, two signal processing units and, a luminance-curve converter, a display device, a histogram-extracting unit, and a characteristic-control-data output unit. The unit sets a characteristic to the luminance-curve converter in accordance with histogram distribution data. The display apparatus further comprises a first control-signal generating unit, a second control-signal generating unit and a selector. The unit generates ...

A method of driving a liquid crystal display includes arranging an externally provided first data into a histogram for each frame, producing a second data having an expanded contrast using the histogram, determining a control value by extracting a peak value at a position where brightness components are concentrated in a distribution, and controlling a brightness of a back light in accordance with a gray level of the control value.

Several pyrotechnic smoke screen sets are arranged on top of each other. Each of them has an igniter and a decomposition sets. They are in separate containers which, in succession, are ignited by a delay device at a desired interval.

A display includes a light modulator, a source of light, and a control for controlling the intensity of light from the source supplied to the light modulator thereby to provide images of good contrast for both bright and dark scenes. A method of displaying an image using a passive light modulating display apparatus includes controlling the intensity of light illuminating the display apparatus as a function of a brightness characteristic of the image.

A pyrotechnic fan rack for mounting a plurality of individual fireworks pieces in a fanned array. The rack has an elongated body with an arcuate top profile and a flat base. Mounting ears are formed on the base to secure the rack to a surface. A series of sockets are formed through the top wall of the body along the horizontal length of the body. Each socket is formed in the body with its axis in preselected fixed angle relative to the axis of adjacent sockets. Tubes containing fireworks pieces ...

A plurality of propellant cartridges are serially connected with each other to form a band that may be rolled up for utilization in a commercial device, such as a riveting gun. The cartridges may be attached to a band by extending their electrical leads through the band for clamping the cartridges to the band, bonding the cartridges to the band, or providing the cartridges with a force fit in recesses of the band, for example. Also, propellant carrying cases may be formed in pairs for serial con...

A display apparatus includes a liquid crystal display panel and an illuminator disposed at the back of the panel for emitting at least two illumination lights having directivities in different directions toward the panel. The illuminator includes a light guide plate made of transparent material whose one end surface serves as a light entrance end surface, whose one plate surface serves as a light exit surface, and whose other plate surface serves as a light direction changing surface for changin...

A method for dynamically adjusting the screen brightness of a pump screen display. The method includes providing a medical pump including a screen display having a first screen brightness and a second screen brightness. The method further includes providing a medication management unit operatively connected to the medical pump where the medication management unit is configured to transmit operating instructions to the medical pump. The operating instructions transmittable from the medication man...
