Abstract
A cathode ray tube (CRT) device is disclosed that increases image resolution. The CRT device includes a plurality of electron guns to produce a plurality of electron beams. A plurality of separate phosphor dots corresponding to separate colors are produced when impacted by the electron beams. The CRT device also includes steering electronics to guide the electron beams to the plurality of separate phosphor dots that form part of separate and shifted color planes.
Claims22
A cathode ray tube (CRT) device comprising:
- a plurality of electron guns to produce a plurality of electron beams;
- a plurality of separate phosphor dots corresponding to separate colors produced when impacted by the electron beams;
- and
- steering electronics to guide the electron beams to the plurality of separate phosphor dots that form part of separate and shifted color planes.
A method for a cathode ray tube (CRT) device, the method comprising:
- producing a plurality of electron beams;
- and
- steering the electron beams to a plurality of separate phosphor dots that form part of separate and shifted color planes.
13 The method of claim 11, further comprising:
- effecting subpixel rendering.
The method of 13, further comprising:
- effecting a timing such that a plurality of colored image data is offset to each other by a spatial and temporal amount.
A cathode ray tube (CRT) device comprising:
- a plurality of electron guns to produce a plurality of electron beams;
- a plurality of separate phosphor dots corresponding to separate colors produced when impacted by the electron beams;
- steering electronics to guide the electron beams to the plurality of separate phosphor dots that form part of separate and shifted color planes;
- and
- a subpixel clock coupled to the steering electronics and to effect subpixel rendering.
