Abstract
A technique capable of displaying an efficient bright image in an image display apparatus using electron sources is provided. The image display apparatus includes a plurality of electron sources, and a plurality of phosphors provided so as to be opposed to the electron sources, light being emitted by the phosphors in response to electrons emitted from the electron sources. The electron sources are capacitive electron sources formed by sandwiching an insulation layer between two metal layers. And two capacitive electron sources electrically connected in series are disposed so as to be associated with each of the phosphors.
Claims11
An image display apparatus comprising:
- a plurality of electron sources arranged in a matrix form;
- and
- a plurality of phosphors provided so as to be opposed to the electron sources, light being emitted by the phosphors in response to electrons emitted from the electron sources,
- wherein
- the electron sources are capacitive electron sources formed by sandwiching an insulation layer between two metal layers, and
- at least two capacitive electron sources electrically connected in series are disposed so as to be associated with each of the phosphors.
An image display apparatus comprising:
- a first substrate having red, blue and green phosphors provided thereon;
- and
- a second substrate having at least two electron sources provided so as to be associated with each of the red, blue and green phosphors,
- wherein
- the electron sources are MIM type electron sources formed by sandwiching an insulation layer between two metal layers, and
- the two MIM type electron sources are electrically connected in series.
An image display apparatus comprising:
- a cathode substrate having m row wires and n column wires formed thereon, and having (m×n) electron sources at intersections of the row wires and the column wires arranged in a matrix form;
- an anode substrate having phosphors of three colors, i.e., blue, green and red colors formed thereon so as to be opposed to the electron sources;
- data drive circuits for applying drive signals based on a video signal to the n column wires;
- and
- scan drive circuits for applying a selection signal for selecting at least one row, successively to the m row wires in a column direction,
- wherein
- the electron sources are capacitive electron sources formed by sandwiching an insulation layer between two metal layers, and
- at least two electron sources are connected in series so as to be associated with each of the blue, green and red phosphors.
