Assignee:

U.S. Philips Corporation - New York NY

International Classification:

F21M 1500

US Classification:

362228

Abstract:

The present invention is directed to illumination structures useful in display systems for projection video and television devices performing with high efficiency and good color rendition. Such illumination sources include a light source having an inner and outer envelope with plane mirrors within the outer envelope to direct reflected light, a light source providing randomly polarized light with polarizing structure for passing a desired polarization of the polarized light, and an arc lamp having at least two arcs for supplying uniform illumination in two dimensions. These illuminating structures enable significantly improved illumination in the appropriate projection video and television systems.

International Classification:

H04N 931
H04N 306
H04N 308

US Classification:

348196

Abstract:

A color projection video system utilizing only a single light valve. A white light source is separated into into red, green and blue bands. Scanning optics cause the RGB bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of panels on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. The device includes circuitry to synchronize the illumination of the light valve with the video signal and to minimize video breakup when changing video sources.

Appl. No.:

7/146528

Inventors:

Robin B. Rumbolt - Knoxville TN

Daniel J. Dargis - Knoxville TN

Assignee:

North American Philips Corporation - New York NY

International Classification:

H04N 544

US Classification:

3581941

Abstract:

A remote control transmitter, preferably a universal or reconfigurable remote control transmitter, is incorporated into a television receiver. Mounting a light emitting source such as a light emitting diode in a line of sight or a wired connection with an external tuning system such as that of a VCR or cable converter, and modification of the television tuning system to cause the transmission of activating signals to the remote control transmitter, allows functions which are channel associated and which are therefore generally suppressed when a remote tuning system is used to remain in force.

Inventors:

William F. Guerinot - Knoxville TN

Assignee:

North American Philips Corporation - New York NY

International Classification:

H04N 3223

US Classification:

358245

Abstract:

A wide screen television monitor capable of displaying standard width picture in which uneven "Coulomb aging" is minimized. The television monitor includes circuitry for causing the standard width picture to cyclically traverse the width of the display screen of the television monitor in accordance with a prescribed function. The period of repetition of this movement is of such a duration that a casual observer of the television monitor is unaware of the movement of the picture.

Abstract:

Display systems useful for projection video and television systems are provided to perform with high efficiency and good color rendition. In these systems, color may be provided, as one example, by various light valves, such as liquid crystal displays. Each of the liquid crystal displays are positioned at equal path distances from an illuminating subsystem, and have equal path distances from the light valves to a projection subsystem. This enables optimum illumination of each of the light valves. Various embodiments of arranging the light valves, as well as providing illumination are described.
