Abstract:
A large screen emissive display operating at atmospheric pressure includes pixels, the red, green, and blue subpixels of which are excited by UV laser light scanned onto the subpixels by a pixel activation mechanism. The pixel activation mechanism includes three grating light valves (GLVs) that are controlled by a processor in response to a demanded image to modulate the UV light as appropriate to produce the demanded image. A refraction layer can be associated with a display such that respective beams are refracted onto red, green, and blue subpixels of the display.
Abstract:
A screen for a cathode ray tube and a method for manufacturing the screen are provided. The screen for a cathode ray tube includes: a phosphor film formed on the inner front surface of a panel where at least one stud pin is mounted, the phosphor film including phosphor layers; a metal layer formed on the phosphor film, which reflects light emitted from the phosphor layers toward the front side of the panel; and a gas exhaust member extended from the metal layer, which provides a path for gas to exhaust, the gas being generated as a filming layer interposed between the phosphor film and the metal layer to make the thickness of the phosphor film uniform is decomposed. To manufacture this screen, a guide block having a mask pattern, which corresponds to a pattern of a metal layer and gas exhaust member to be formed as a single body inside the panel on which the phosphor film and a filming layer have been formed, is fitted into the panel. After evacuating a processing space where the panel is loaded, a precursor of the metal layer is heated to evaporate, thereby simultaneously forming the metal layer on the filming layer to cover the phosphor film and forming the gas exhaust member to selectively extend from the boundary of the metal layer as a pattern.

A CRT panel glass and a CRT wherein a surface treating film is formed on an outer surface of a CRT panel so that overall transmittance distribution and reflectance distribution within an effective picture plane satisfy specific mathematical expressions, whereby, even with a flattened panel glass, brightness and contrast are uniform over the entire surface of the image display plane, and their production method.
Abstract:
A low excitation voltage luminescent phosphor screen structure is presented applicable to vacuum visual displays and other devices. The phosphor grains utilized in the luminescent screen are strongly bonded with molecular colonies of conductive metal oxide, which allows for the deposited layers of these phosphors to be excited to luminosity at significantly lower voltages than were previously possible. Also presented are methods for production and increasing the quality and control of low cost mass production of such luminescent screens with no toxic gas emission.
Abstract:
Picture display device comprising a cathode ray tube whose display screen (10) is provided with index electrodes (20, 21) comprising elongated conducting elements disposed substantially parallel to an axis of symmetry (50) of the display screen (10). In operation, the magnetic field of the deflection system of the cathode ray tube induces unwanted crosstalk on said index electrodes (20, 21). By cross-connecting one end (30a) of a conducting element (31) of an index electrode (20) to the opposite side end (40a) of another conducting element (41) of said index electrode (20), said crosstalk on said index electrode (20) is reduced.
