Claims
- 1. A gas flat display tube comprising:
- a glass container having a discharge gas therein;
- first cathodes installed in said glass container an for emitting electrons;
- a plurality of anodes extending vertically and arranged by a predetermined interval on one side of said glass container, for absorbing the emitted electrons;
- a plurality of phosphors arranged in a matrix form on said plurality of anodes and becoming luminous by the electrons absorbed into said anodes; and
- a plurality of first gates extending horizontally and arranged by a predetermined interval in said glass container, for controlling said emitted electrons to be absorbed into said anodes, wherein the number of said first gates is same as that of vertical drive pulses so that said vertical drive pulses are applied to said first gates.
- 2. A gas flat display tube as claimed in claim 1, wherein said phosphors are formed horizontally in the sequence of red, green and blue phosphors on said plurality of anodes.
- 3. A gas flat display tube as claimed in claim 2, wherein the number of said anodes is the same as that of horizontal drive pulses by grouping red, green and blue phosphors as one so that said horizontal drive pulses are applied to said anodes.
- 4. A gas flat display tube as claimed in claim 3, wherein a video signal is applied to said anodes corresponding to said red, green and blue phosphors so as to change a luminous color.
- 5. A gas flat display tube as claimed in claim 1, further comprising second cathodes formed between said first cathodes and first gates and for radiating the electrons emitted from said first cathodes.
- 6. A gas flat display tube as claimed in claim 5, further comprising second gates formed between said second cathodes and first gates and for accelerating and transmitting the emitted electrons to said first gates.
- 7. A gas flat display tube as claimed in claim 6, wherein rectangular holes are formed in a matrix form in said second gates.
- 8. A gas flat display tube as claimed in claim 7, wherein said rectangular holes are formed vertically as many as the number of vertical drive pulses.
- 9. A gas flat display tube as claimed in claim 7, wherein said rectangular holes are formed horizontally as many as the number of horizontal drive pulses.
- 10. A gas flat display tube as claimed in claim 6, wherein a dielectric is formed between said first and second gates for the purpose of electric insulation.
- 11. A gas flat display tube as claimed in claim 5, further comprising third gates formed between said first gates and anodes and for accelerating and transmitting the electrons passing said first gates to said anodes.
- 12. A gas flat display tube as claimed in claim 11, wherein a dielectric is formed between said first and third gates for the purpose of electric insulation.
- 13. A gas flat display tube as claimed in claim 5, wherein said second cathodes are netlike and has the same size as that of said anodes.
- 14. A gas flat display tube as claimed in claim 13, wherein both sides of said first and second cathodes are coated of an oxide.
- 15. A gas flat display tube as claimed in claim 5, wherein a variable resistor for preventing an electron avalanche is coupled to said second cathode.
- 16. A gas flat display tube as claimed in claim 1, wherein said first cathodes are made with metal plates.
- 17. A gas flat display tube as claimed in claim 1, wherein said anodes are made up of vertical metal lines extending vertically and coated by a predetermined interval on said glass container.
- 18. A gas flat display tube as claimed in claim 17, wherein said third gates are formed in the same form as that of said second gates.
- 19. A gas flat display tube as claimed in claim 17, wherein a dielectric is formed between said vertical metal lines for the purpose of electric insulation.
- 20. A gas flat display tube as claimed in claim 1, wherein luminescence dielectrics are arranged vertically by a predetermined interval so that said phosphors are disposed in a matrix form.
- 21. A gas flat display tube as claimed in claim 20, wherein said luminescence dielectric is formed so that the number of said phosphors is the same as that of vertical drive pulses.
- 22. A gas flat display tube as claimed in claim 1, wherein said phosphors are arranged vertically as many as the number of said cathodes.
