Abstract

A display apparatus of the present invention is featured in that luminance-controllable display modules are attached as pixels to a flexible net having a mesh portion. To be more specific, the display apparatus of the present invention is characteristically provided with a flexible net made in such manner that a flexible net member (which is preferably transparent) constitutes a display screen area, luminance-controllable display modules attached to the flexible net and arranged in a matrix fashion, and two-dimensional selection/display control means (e.g., a master PC[1], slaves PC[3], X and Y control units [11X˜, 11Y˜], etc.) for two-dimensionally selecting the display modules and controlling the luminance of the selected ones of the display modules.

Claims

1. A display apparatus comprising:

a flexible net formed of a flexible member so as to constitute a net-like display screen area having a plurality of mesh portions;

a plurality of luminance-controllable display modules attached to the flexible net as pixels; and

two-dimensional selection/display control means for two-dimensionally selecting the display modules and controlling luminance of selected ones of the display modules,

each of said plurality of display modules further compromising;

a wiring board having a plurality of corner portions into which luminance control circuits each including light-emitting elements are respectively incorporated;

a display board having a shape and a size identical to a shape and size of the wiring board and having a window for allowing the light-emitting elements to be exposed; and

attachment means for integrally attaching the wiring board and the display board to the flexible net, by respectively arranging the wiring board and the display board on obverse and reverse sides of the flexible net in such a manner that the wiring board and the display board face each other, while simultaneously respectively coupling the plurality of the corners of the wiring board with the plurality of the corners of the display board with a plurality of coupling pins such that each of the plurality of coupling pins penetrates different mesh portions of the flexible net.

2. A display apparatus according to claim 1, wherein said flexible net is characterized by being integrally formed of transparent resin.

3. A display apparatus according to claim 1, wherein each of the display modules is made by assembling three-primary color LEDs of red, blue and green on a wiring board, along with sample-and-hold circuits and a LED driver.
