    摘要: Low-profile, large screen display using a rear projection array system using an array of micro projectors, each comprised of a micro-display device, several optical components, a red/green/blue light emitting diode light source, a light sensor for each color and power driving and interface electronics circuits. The plurality of Micro Projectors are arranged as an array along the vertices of a grid to conjointly project a uniform and seamless image comprised of the collective projected output pixels (sub-image) of the array of Micro Projectors. The Array Controller processes output signals generated by the light sensors embedded in each Micro Projector in the array and generates pixel gray scale input and light source control signals for each of the Micro Projectors in the array to maintain uniform luminance and chromaticity (color-point) across the array. Various features are disclosed. including tapering and diffusion of the sub-image boundaries to form a single large display.

    摘要: The invention is related to a new kind of plasma display panel control. A known principle for PDP control is based on a combination of sub-field addressing and priming. Within the priming period all the plasma cells of the panel are pre-excited by a strong voltage pulse. This treatment of the cells produces a slight background luminance which is a drawback for picture quality aspects because the achievable contrast is reduced. According to the invention it is proposed to use self-priming sub-fields and refreshing sub-fields instead of this hard priming period. With these concepts it is assured that the cells which ought to be black remain black. Self-priming sub-fields reduce or eliminate the need for priming, thus making dark areas darker, while refreshing sub-fields, can be addressed faster. In practice, the number of refreshing sub-fields in a frame period is higher than the number of the self-priming sub-fields. Therefore, the total addressing time can be reduced with this new technique. The faster addressing leaves more time for sustain pulses, thus allowing bright areas that are brighter. This is especially advantageous for PDP monitors connected to 75Hz multimedia sources.

    摘要: A small projection display apparatus which suppresses optical paths of incident and output light in a reflection valve from overlapping; and a rear projector and a multi-vision system using the same. The projection display apparatus includes an illumination optical system for collecting light radiated, forming illumination light, a reflection type light valve for reflecting the illumination light to output modulated light forming an optical image, a projection lens system for projecting an optical image formed by the reflection type light valve, and a lens element. The lens element is composed of one plano-convex lens, and is placed between the valve and the projection lens system with a convex surface directed to the projection lens system. The illumination light passes through the lens element to illuminate the reflection type light valve, and the modulated light output passes through the lens to be incident upon the projection lens system.

    摘要: In a PDP driving circuit, first and second inductors are coupled to a panel capacitor. The driving circuit stores a first energy in the first inductor through a current in the first direction while the voltage at the panel capacitor is maintained to be a first voltage, and uses the first energy and resonance between the panel capacitor and the first inductor to reduce the voltage at the panel capacitor to a second voltage. Next, the driving circuit maintains the voltage at the panel capacitor to be the second voltage, recovers the energy remaining in the first inductor, stores a second energy in a second inductor through a current in the second direction, and uses the energy stored in the second inductor to increase the voltage at the panel capacitor to the first voltage. Therefore, rising and falling time of the voltage at the panel capacitor is shortened, and zero-voltage switching is possible when the driving circuit has a parasitic component.

    摘要: The procedure of the invention acquires a maximum RB value, which is a largest value of an R signal component and a B signal component, on the assumption that the signal format of an input video signal is an RGB signal, and obtains an RGB probability corresponding to a degree of largeness of the maximum RB value. The procedure also acquires a minimum color difference value, which is a smallest value of a color difference signal component, on the assumption that the signal format of the input video signal is a Y/color difference signal, and obtains a color difference probability corresponding to a degree of smallness of the minimum color difference value. The procedure compares the RGB probability with the color difference probability and thereby determines whether the signal format of the input video signal is the RGB signal or the Y/color difference signal. This arrangement effectively enhances the accuracy of discrimination between the RGB signal and the Y/color difference signal.

    摘要: In a display device such as a thin-film EL display device, etc. formed with a dielectric layer disposed between a plurality of scanning side electrodes and a plurality of data side electrodes in the direction for them intersecting to each other, a modulation voltage, varied according to gradation display data is applied to the data side electrodes, and a positive or negative writing voltage is applied to the scanning side electrodes in a line order for a gradation display different in brightness. Binary coded signals corresponding to each gradation of a gradation display are used as the gradation display data. The logical value of the binary coded signal is inverted according to the polarity of the writing voltage. Thus, a common gradation display can be performed from one binary coded signal for both the negative driving that applies a negative writing voltage and the positive driving that applies a positive writing voltage. As a result, by only by adding a data conversion circuit for inverting a binary coded signal, the function that converts the correspondence relation between the gradation to be displayed and the gradation display data depending on the negative driving or positive driving can be incorporated.
