Title: (EN) DISPLAY DEVICE COMPRISING LIGHT GUIDE
(JA) 光ガイドを備えた表示装置
Abstract:
(EN) PROBLEM TO BE SOLVED: To provide a display device which gives an improvement of image quality.

SOLUTION: The display device includes a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible, which can be achieved by making the force act at the location where the optical contact takes place and/or by reducing or eliminating other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals' forces and/or chemical forces).

【課題】画質の向上を示す表示装置を提供する。
【解決手段】本発明表示装置は光ガイドと可動素子を備える。
選択手段により可動素子に局部的に力を及ぼすことによって、可動素子と光ガイドとの間に光学的接触をもたらすことができる。
光は光学的接触が生起する位置において表示装置から出る。
選択手段により及ぼされる力をできるだけ効率よく利用する手段を講ずる。
これは、力を光学的接触が生起する位置に作用させることにより及び、又は(特に圧力差、静電帯電、表面応力、ファンデルワールス力及び、又は化学的力により生ずる)付着力を低減又は除去することにより達成することができる。
