Abstract
Disclosed is a display device having a beam index type color CRT that includes an index signal controller for controlling input and output of index signals, an index memory for temporally saving the index signals in units corresponding to of a screened image of a scene on a screen panel, and a switch for switching the index signals that is under the control of the index signal controller.
Claims8
A beam index type color CRT comprising;
- a photo sensor for outputting an index signal;
- an RGB switch for outputting a color signal;
- an index signal controller for controlling and coupling the index signal and color signal;
- an index memory for temporally saving the coupled signals corresponding to a screened image of a scene on a screen panel for re-use by the CRT;
- and
- a second switch for controlling the flow of signals from the RGB switch and the index memory to the screen panel under the control of the index signal controller.

A beam index type color CRT comprising:
- a means for receiving an index beam;
- and
- a means for controlling generation of an electron beam in response to an output signal from said means for receiving an index beam, said controlling means having a switch means and a memory.
A beam index circuit for a color CRT having a screen panel, comprising;
- an index signal controller;
- an index memory configured to temporally save an index signal corresponding to a screened image of a scene on the screen panel under control of the index signal controller;
- an RGB switch configured to output a color signal;
- and
- a second switch configured to couple the color signal from the RGB switch to the screen panel under the control of the index signal controller.
