ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a video display or television monitor. More particularly, this invention relates to such a display which is relatively flat or thin.
Considerable effort has been taken over the past twenty years to develop flat televisions or video monitors. Such screens or monitors could hang on the wall, be stored in a desk top or transported in a briefcase.
Although laptop and notebook computers have appear on the market with flat screens, there is always some compromise with respect to clarity or contrast. In addition, no such screen has been capable of producing satisfactory color.
OBJECTS OF THE INVENTION
An object of the present invention is to provide a flat television or video display.
It is a related object of the present invention to provide a thin television or video display.
Another object of the present invention is to provide such a television or video display which is capable or producing color images suitable for projection or direct viewing.
Another, more particular, object of the present invention is to provide such a television or video display which is easy to manufacture.
These and other objects of the present invention will be apparent from the drawings and detailed descriptions herein.
SUMMARY OF THE INVENTION
A substantially flat television display comprises, in accordance with the present invention, a plurality of visible multi-wavelength laser or superluminescent diodes mounted in a two-dimensional array to a substantially flat substrate or carrier. The diodes are protected by a cover sheet or internal coating which is connected to the substrate or carrier. Energization componentry is operatively connected to the diodes for energizing the diodes in accordance with an incoming video signal to reproduce an image embodied in the video signal. In a color television or video display, the superluminescent or laser diodes are tuned to different frequency ranges or triades of fixed RGB superliuminescent values, so as to reproduce the image in color. The protective cover sheet may function also to disperse light emitted by the superluminescent or laser diodes, to generate a more continuous image.
A television or video display in accordance with the present invention is substantially flat and produces a sharp, clear image. In addition, color reproduction and brightness is satisfactory, if not excellent.
In accordance with a feature of the present invention, the substrate or carrier and the protective cover sheet are flexible to thereby provide a malleable video screen. Thus, such a video screen may be shaped to conform to any number of pre-existing support surfaces to which the video screen or display is mounted. For example, the video screen may be curved to assume a cylindrical shape in being placed on a column. Other support surfaces include car windshields and seat backs.
