Abstract

The present invention provides an array display apparatus in which multiple light-emitting tubes each having a fluorescent substance layer inside are aligned and a discharge is generated within these multiple light-emitting tubes, whereby the fluorescent substance layers within the light-emitting tubes are caused to emit light thereby to display an image. The array display apparatus displays an image of uniform luminance irrespective of the planar shape of a display surface when image data representing a uniform image is inputted.

Claims (36)

1. An array display apparatus, comprising:

a plurality of light-emitting tubes, which each have a fluorescent substance layer inside and are arrayed parallel to each other and along a display surface at least a part of which has a curvature;

a front surface supporting member and a back surface supporting member, which support the light-emitting tubes by sandwiching the light-emitting tubes and extend over on the side of the display surface and on the side of a back surface, respectively;

a plurality of display electrodes, which are formed on a surface opposite to the light-emitting tubes of the front surface supporting member and extend in a direction in which the display electrodes span the light-emitting tubes;

a plurality of signal electrodes, which are formed on a surface opposite to the light-emitting tubes of the back surface supporting member in a manner corresponding to each of the light-emitting tubes and extend in a direction along the light-emitting tubes; and

a luminance adjusting section which adjusts luminance by each of the light-emitting tubes according to a partial curvature of the display surface, and

wherein the luminance adjusting section includes a feature that the display electrodes have such an electrode structure that transmittance differs depending on the partial curvature of the display surface.

2. An array display apparatus, comprising:

a plurality of light-emitting tubes, which each have a fluorescent substance layer inside and are arrayed parallel to each other and along a display surface at least a part of which has a curvature;

a front surface supporting member and a back surface supporting member, which support the light-emitting tubes by sandwiching the light-emitting tubes and extend over on the side of the display surface and on the side of a back surface, respectively:

a plurality of display electrodes, which are formed on a surface opposite to the light-emitting tubes of the front surface supporting member and extend in a direction in which the display electrodes span the light-emitting tubes;

a plurality of signal electrodes, which are formed on a surface opposite to the light-emitting tubes of the back surface supporting member in a manner corresponding to each of the light-emitting tubes and extend in a direction along the light-emitting tubes; and

a luminance adjusting section which adjusts luminance by each of the light-emitting tubes according to a partial curvature of the display surface, and

wherein the luminance adjusting section includes a feature that the display electrodes have such an electrode structure that discharge efficiency differs depending on the partial curvature of the display surface when the same voltage is applied.

3. An array display apparatus, comprising:

a plurality of light-emitting tubes, which each have a fluorescent substance layer inside and are arrayed parallel to each other and along a display surface at least a part of which has a curvature;

a front surface supporting member and a back surface supporting member, which support the light-emitting tubes by sandwiching the light-emitting tubes and extend over on the side of the display surface and on the side of a back surface, respectively;

a plurality of display electrodes, which are formed on a surface opposite to the light-emitting tubes of the front surface supporting member and extend in a direction in which the display electrodes span the light-emitting tubes;

a plurality of signal electrodes, which are formed on a surface opposite to the light-emitting tubes of the back surface supporting member in a manner corresponding to each of the light-emitting tubes and extend in a direction along the light-emitting tubes; and

a luminance adjusting section which adjusts luminance by each of the light-emitting tubes according to a partial curvature of the display surface, and

wherein the luminance adjusting section includes a feature that the thickness of the fluorescent substance layer within the light-emitting tubes which form regions of the display surface differs depending on the curvature of each of the regions.

4. An array display apparatus, comprising:

a plurality of light-emitting tubes, which each have a fluorescent substance layer inside and are arrayed parallel to each other and along a display surface at least a part of which has a curvature;

a front surface supporting member and a back surface supporting member, which support the light-emitting tubes by sandwiching the light-emitting tubes and extend over on the side of the display surface and on the side of a back surface, respectively;

a plurality of display electrodes, which are formed on a surface opposite to the light-emitting tubes of the front surface supporting member and extend in a direction in which the display electrodes span the light-emitting tubes;

a plurality of signal electrodes, which are formed on a surface opposite to the light-emitting tubes of the back surface supporting member in a manner corresponding to each of the light-emitting tubes and extend in a direction along the light-emitting tubes; and

a luminance adjusting section which adjusts luminance by each of the light-emitting tubes according to a partial curvature of the display surface, and

wherein the luminance adjusting section includes a feature that the position of the fluorescent substance layer disposed within the light-emitting tubes which form regions of the display surface differs depending on the curvature of each of the regions.

5. An array display apparatus, comprising:

a plurality of light-emitting tubes, which each have a fluorescent substance layer inside and are arrayed parallel to each other and along a display surface at least a part of which has a curvature;

a front surface supporting member and a back surface supporting member, which support the light-emitting tubes by sandwiching the light-emitting tubes and extend over on the side of the display surface and on the side of a back surface, respectively;

a plurality of display electrodes, which are formed on a surface opposite to the light-emitting tubes of the front surface supporting member and extend in a direction in which the display electrodes span the light-emitting tubes;

a plurality of signal electrodes, which are formed on a surface opposite to the light-emitting tubes of the back surface supporting member in a manner corresponding to each of the light-emitting tubes and extend in a direction along the light-emitting tubes;

a luminance adjusting section which adjusts luminance by each of the light-emitting tubes according to a partial curvature of the display surface; and

a driving circuit, to which image data is input and which drives the display electrodes and the signal electrodes according to the image data, thereby causing an image by luminance distribution to be displayed on the display surface, and

wherein the luminance adjusting section includes a data conversion circuit, to which image data is input and which gives weight, which differs depending on the curvature of each of regions constituting the display surface, to a pixel value of a pixel which is taken partial charge of by the light-emitting tube corresponding to each of the regions, generates new image data thereby and inputs the new image data to the driving circuit.
