摘要： A camera comprises an imaging system having a first depth of field for one or more first colours and a second depth of field, smaller than the first depth of field, for one or more second colours. The imaging system may comprise an iris with a first aperture for the first colour or colours and a second aperture, which is larger than the first, for the second colour or colours. The first aperture may be defined by an outer opaque ring (1) and the second by an inner chromatic ring (2). The inner ring (2) blocks the first colour(s) and passes the second colour(s). The image formed of the first colour(s) is sharper and its sharpness may be transposed by image processing to the other images.

摘要： A camera including an imaging system having a first depth of field for one or more first frequencies of optical radiation and a second depth of field, smaller than the first depth of field, for one or more second frequencies of optical radiation. The imaging system includes an iris having a first aperture for the first frequency(ies) of optical radiation and a second aperture, larger than the first aperture, for the second frequency(ies) of optical radiation. The first aperture is defined by an outer opaque ring and the second aperture is defined by an inner chromatic ring. The inner chromatic ring blocks the first frequency(ies) and passes the second frequency(ies) such that the image formed by the first frequency(ies) is sharper than the image formed by the second frequency(ies), and that sharpness may be transposed to other images by known image processing techniques.

摘要： A display device and method driving a display device makes use of the dynamic variation in the brightness of a surface mode liquid crystal device cell having a liquid crystal layer with a non-zero twist angle. The liquid crystal layer is switched before the equilibrium value of the brightness has been reached, so as to make use of the non-equilibrium increased brightness and so increase the brightness of the display.

摘要： A ferroelectric liquid crystal device includes a layer of ferroelectric liquid crystal material contained between a pair of substrates, a first plurality of electrodes and a second plurality of electrodes defining a plurality of addressable liquid crystal pixels. A driving arrangement is provided for applying a first signal (Strobe) in succession to the first plurality of electrodes and for applying a plurality of second signals (Data) simultaneously to the second plurality of electrodes. The plurality of second signals are arranged to include non-rectangular wave signals which have a lower harmonic content than a rectangular wave. Non-uniform heating of the device as a result of the application of the second signals (Data) is reduced with consequent improvement in device performance.

摘要： An addressable matrix display comprises an addressable matrix of pixels, a first set of electrode tracks on one side of the matrix and a second set of electrode tracks on the other side of the matrix. The sets of electrode tracks cross one another at the locations of the pixels, and the pixels are switchable by the application of respective switching waveforms to the electrode tracks. Furthermore at least one of the electrode tracks has a resistance which varies along the length of the electrode track in order to provide increased temperature uniformity over the display due to power dissipation during switching by the switching waveforms applied to the electrode tracks. More particularly the resistance in an intermediate section of the electrode track is greater than the resistance in two end sections of the electrode track.

摘要： A display device is provided, including a signal transmission mechanism that makes it possible to reduce the number of pins on an FPC board connected to a TFT substrate or eliminate the necessity for the FPC board, and that can be readily applied to a compact device.The present liquid crystal display device includes light detectors, a receiver circuit, a display control circuit, a video signal line drive circuit, a scanning signal line drive circuit, and a display portion, which are formed on a TFT substrate of a liquid crystal display panel, and it also includes white LEDs, and an LED drive circuit, which are included in a backlight portion. The LED drive circuit drives the white LEDs, each emitting a light (modulation) signal LS in accordance with an externally-provided video signal VS. The receiver circuit generates (demodulates) the video signal VS based on a signal received via the light detector. Such an optical transmission mechanism makes it possible to reduce the number of pins on the FPC board or eliminate the FPC board.

摘要： An optical element includes a liquid crystal layer; and at least one alignment layer in contact with the liquid crystal layer, the at least one alignment layer being formed from a mixture including a first reactive mesogen and a second reactive mesogen. Each of the first and second reactive mesogens have at least one polymerizable functional group, and a number of polymerizable functional groups of the second reactive mesogen is smaller than that of the first reactive mesogen. A ratio of the second reactive mesogen to the first reactive mesogen in the mixture is determined so as to provide a predetermined pretilt angle with liquid crystal molecules in the liquid crystal layer.
