摘要:
A method for forming a coating film on an internal surface of an elongated tube, includes longitudinally holding the elongated tube, applying a coating solution to the internal surface of the elongated tube; and drying the coating solution while carrying out a heat process for sequentially heating the elongated tube by using a heat source. The heat process includes adjusting the descending rate of the heat source so that a through-hole in the elongated tube is clogged with the coating solution whose viscosity is reduced by heating of the heat source, and sucking the through-hole in the elongated tube from the lower side thereof so that a portion of the through-hole that is clogged with the coating solution moves downwards along the elongated tube.

A light-emitting tube array display device includes a light-emitting tube array, a flexible sheet and a plurality of electrodes. The light-emitting tube array is constituted of a plurality of light-emitting tubes arranged in parallel. Each of the light-emitting tubes consists of narrow tube having a phosphor layer disposed and discharge gas filled inside. The flexible sheet is capable of flatly supporting the light-emitting tube array and deforming the light emitting tube array in a direction perpendicular to a longitudinal direction of the light-emitting tubes. The plurality of electrodes are formed on a face of the flexible sheet opposed to the light-emitting tubes, which are capable of generating discharge inside the light-emitting tubes by an application of voltage. Each of the electrodes is formed of a metal film having a mesh pattern, a ladder pattern, or a comb-shape pattern.

In accordance with an aspect of the present invention, a color display device (10) includes a plurality of gas discharge tubes disposed side by side. The gas discharge tubes have respective phosphor layers (4R, 4G, 4B) of different materials for different colors disposed therein and containing discharge gas therein. Each of the gas discharge tubes has a plurality of light-emitting points disposed along the length thereof. The color display device further includes a plurality of display electrodes disposed on the display screen side of the gas discharge tubes, and a plurality of signal electrodes (3) disposed on the rear side of the gas discharge tubes. Voltage control layers (6R, 6G, 6B) are disposed between the phosphor layers and the signal electrodes. The voltage control layers are made of materials which change firing voltages applied between the display electrodes and the signal electrodes. The materials of the voltage control layers are selected for the different materials of the different phosphor layers so as to minimize the difference of the firing voltages for the plurality of gas discharge tubes.
