Description
ストレッチャブル表示装置は、反ったり伸びたりしても画像表示が可能な表示装置と称され得る。ストレッチャブル表示装置は、従来の一般的な表示装置と比べて高いフレキシビリティを有し得る。そこで、ユーザがストレッチャブル表示装置を反るようにしたり伸びるようにしたりする等、ユーザの操作によってストレッチャブル表示装置の形状が自由に変更され得る。例えば、ユーザがストレッチャブル表示装置の末端を持って引っ張る場合、ストレッチャブル表示装置は、ユーザの力により伸び得る。または、ユーザがストレッチャブル表示装置を平らでない壁面に配置させる場合、ストレッチャブル表示装置は、壁面の表面の形状に沿って反るように配置され得る。また、ユーザにより加えられる力が除去される場合、ストレッチャブル表示装置は、また本来の形態に戻ることができる。
図2は、本発明の一実施例に係るストレッチャブル表示装置の拡大平面図である。図3は、図4のIII-III’断面図である。説明の便宜のために、図1を共に参照して本発明の一実施例に係るストレッチャブル表示装置100について説明する。
図2及び図3を参照すると、ストレッチャブル表示装置100は、下部基板DS、複数の第1基板ST1、複数の接続基板CS、複数の接続配線120、複数のパッド130、トランジスタ150及びLED160を含む。
n型層161上には、活性層162が配置される。活性層162は、LED160で光を発する発光層であり、窒化物半導体、例えば、インジウム窒化ガリウム(InGaN)からなり得る。活性層162上には、p型層163が配置される。p型層163は、窒化ガリウム(GaN)にp型不純物を注入して形成され得る。
図4は、本発明の一実施例に係るストレッチャブル表示装置の接続配線を示す図である。図5は、図4のV-V’に沿った断面図である。
