High-density light-emitting-diode array utilizing a plurality of isolation channels

A light-emitting-diode array, comprising:

• a lower layer;
• an upper layer of a semiconducting material of a first conductivity type formed on said lower layer;
• a plurality of isolation channels extending from an upper surface of said upper layer through said upper layer to said lower layer, dividing said upper layer into a plurality of blocks which are electrically isolated from one another;
• a row of light-emitting diodes, each light-emitting diode formed by difflusion of an impurity of a second conductivity type, different from first conductivity type, into said upper layer to form a difflusion area of a second conductivity type within the upper layer, each block among said plurality of blocks including a plurality of said light-emitting diodes;
• a plurality of block electrodes electrically coupled to said upper layer in respective blocks, for driving the light-emitting diodes in said respective blocks;
• and
• a plurality of shared lines disposed parallel to said row of light-emitting diodes and crossing said isolation channels, each shared line among said plurality of shared lines being electrically coupled to a plurality of said light-emitting diodes in different blocks among said plurality of blocks, each light-emitting diode in said row of light-emitting diodes being electrically coupled to just one shared line among said plurality of shared lines.
