Description

本発明は、設置する場所の形状に馴染むように曲げたり、たたんだり出来る電気的に表示が書き換え可能な、形体順応型表示装置に関するものである。  The present invention relates to a shape-adaptive display device that can be rewritten electrically so that it can be bent or folded so as to fit the shape of a place where it is installed.

近年、電気的表示装置(ディスプレイ)は、従来のブラウン管方式から、液晶方式、有機EL(Electro Luminescence)方式へと、より薄い表示装置が作られるようになってきた。情報化社会においては、もはや欠かすことの出来ない表示装置として、進化してきている。  In recent years, thinner electric display devices (displays) have been made from conventional cathode ray tube methods to liquid crystal methods and organic EL (Electro Luminescence) methods. In the information society, it has evolved as a display device that is indispensable.

一方、ロボットの分野では、二足歩行が実現して、ヒューマノイド型ロボットと、社会との関わりが身近になってきている。ヒューマノイド型ロボットに期待される、人の役に立つ機能の一つとして、コミニュケーション分野がある。受付・案内や、介護・医療において、人とロボットとの共存の試みが行われている。  On the other hand, in the field of robots, bipedal walking has been realized, and the relationship between humanoid robots and society has become closer. One of the useful functions expected of humanoid robots is the communication field. At the reception desk / guidance, nursing care / medicine, attempts are made to coexist with humans and robots.

前記有機ELにおいては、フレキシブル基板に、有機EL、と有機TFTを作りこむことにより、曲率半径数ミリの太さの棒に、巻き取れる有機EL装置が登場し、繰り返し巻き取りでも、表示性能に劣化がないことが確認されている。  In the organic EL, by making the organic EL and organic TFT on the flexible substrate, an organic EL device that can be wound on a stick with a radius of curvature of several millimeters has appeared, and even with repeated winding, display performance is improved. It has been confirmed that there is no deterioration.

前記有機ELは、従来の曲げられる特性から、現在、巻き取れる特性にまで、進化してきている。但し、折り曲げられる方向は、まだ、1方向に限定されている。携帯電話や家庭用スクリーンに使うことが、検討されている。今後は、多方向への折り曲げ実現が、期待されている。  The organic EL has evolved from a conventional bending property to a winding property. However, the bending direction is still limited to one direction. It is being considered for use in mobile phones and home screens. In the future, it is expected to bend in multiple directions.

前記ヒューマノイド型ロボットにおいては、自然なコミュニケーションを目指して、アイコンタクトを行いながら対話が可能になっている。人間とロボットで、コミュニケーションをとるなら、ロボットも表情が重要である。人間は、ロボットに顔が有っても、無表情のロボットには、親しみは感じ難い。人に触れる機会の多いロボットには、顔を付けることが、求められている。顔の表情について、空気圧アクチュエータとシリコン製の皮膚やフォームラバーを使った顔ロボットも登場しているが、ぎこちなさは依然として残っている。  In the humanoid robot, dialogue is possible while making eye contact for natural communication. When communicating with humans and robots, facial expressions are also important for robots. Even if a robot has a face, it is difficult to feel familiarity with an expressionless robot. A robot that has many opportunities to touch people is required to have a face. As for facial expressions, facial robots using pneumatic actuators and silicon skin and foam rubber have also appeared, but awkwardness still remains.

前記ヒューマノイド型ロボットは、顔認識という点で、一般的に、顔の各部分や、髪型、陰影、骨格等で顔認証されるとしている。口や瞼は、実際に開く必要は無く、動いている様に、認識出来れば良いことになる。前記問題を鑑みると、人間型骨格に、人間の表情と同様の動きを表示出来る形体順応型表示装置を貼り付ける等により、前記問題を解決することが望まれている。  The humanoid robot is generally face-authenticated by each part of the face, hairstyle, shadow, skeleton, etc. in terms of face recognition. It is not necessary to actually open the mouth and bag, it is only necessary to be able to recognize it as it moves. In view of the above problem, it is desired to solve the above problem by pasting a shape-adapting display device capable of displaying a movement similar to a human expression on a humanoid skeleton.

先行技術文献について本願発明と対比すると、特許文献1には、一定方向に湾曲するフレキシブル装置について提案がされている。データ線をクランク状に屈曲させる、としている。特許文献1に記載の表示装置は、本願発明の、フレキシブル基板上の単位画素間に連結部、と空隙部、とを設けてなり、前記空隙部は、前記単位画素を囲む様に配置することで、あらゆる方向に、柔軟性・伸縮性を獲得する、形体順応型表示装置とは異なる。本願発明の様なフレキシブル基板上の単位画素間に連結部、と空隙部、とを設けてなり、前記空隙部は、前記単位画素を囲む様に配置する言及は無い。  When comparing the prior art document with the present invention, Patent Document 1 proposes a flexible device that bends in a certain direction. The data line is bent in a crank shape. The display device described in Patent Document 1 includes a connection portion and a gap portion between unit pixels on a flexible substrate according to the present invention, and the gap portion is arranged so as to surround the unit pixel. Therefore, it is different from a shape-adapted display device that acquires flexibility and stretchability in all directions. A connecting portion and a gap portion are provided between unit pixels on a flexible substrate as in the present invention, and there is no mention that the gap portion is disposed so as to surround the unit pixel.

特開2009−48007号公報JP 2009-48007 A

人に触れる機会の多いロボットには、顔を付けることが、求められている。顔の表情について、空気圧アクチュエータとシリコン製の皮膚やフォームラバーを使った顔ロボットも登場しているが、ぎこちなさは依然として残っている。無表情な状態や、表情の微妙な動きのズレは、違和感を感じるという問題がある。電気的に顔表情を映し出す場合は、現状では、視覚的にパネルの意識が強く、違和感がある。  A robot that has many opportunities to touch people is required to have a face. As for facial expressions, facial robots using pneumatic actuators and silicon skin and foam rubber have also appeared, but awkwardness still remains. There is a problem that a feelingless feeling is felt when there is no expression or when there is a slight movement of the expression. When electrically expressing facial expressions, currently the panel is visually highly conscious and uncomfortable.

本発明は、このような問題点を解決すべく為されたものであり、人間とロボット等のコミニュケーション分野においては、人間型骨格に馴染み、人間の表情と同様の動きを表示出来る、形体順応型表示装置を提供することを目的とする。  The present invention has been made to solve such problems, and in the communication field such as humans and robots, it is familiar to the humanoid skeleton and can display movements similar to human facial expressions. An object is to provide a display device.

本発明は、凹凸や曲面のある物体へ、表示装置を密着して貼り付け可能とするため、フレキシブル基板上の単位画素間に連結部、と空隙部、とを設けてなり、前記空隙部は、前記単位画素を囲む様に配置することを特徴とする。単位画素は、例えば、3原色の場合、赤色(R)画素、緑色(G)画素、青色(B)画素で、構成する。  In the present invention, in order to allow a display device to be adhered and pasted to an object having unevenness or a curved surface, a connecting portion and a gap portion are provided between unit pixels on a flexible substrate, and the gap portion is The unit pixels are arranged so as to surround the unit pixels. For example, in the case of three primary colors, the unit pixel is composed of a red (R) pixel, a green (G) pixel, and a blue (B) pixel.

フレキシブル基板上の単位画素間に設けてなる前記連結部は、伸縮性を持たせたい方向に対して、斜めに配置することを特徴とする。  The connecting portion provided between the unit pixels on the flexible substrate is arranged obliquely with respect to a direction in which stretchability is desired.

請求項1、請求項2、請求項3の形体順応型表示装置によれば、複雑な凹凸面に馴染む様に、表示面を配置することが出来る。人間とロボットのコミュニケーション手段としての顔表示に使用出来る。前記顔表示においては、より自然な顔表情を表すことが可能である。顔色を紅潮したように変化させることも容易に出来る。個々の対面者の好みの顔表情に合わせることも、容易であるので、対面式の案内ロボットの顔や、介護ロボットの顔表情への活用も期待でき、好適である。その他への適用として、曲面体へ設置して、情報表示・広告表示装置としても使用することが出来る。  According to the form-adapting display device according to the first, second, and third aspects, the display surface can be arranged so as to be adapted to the complicated uneven surface. It can be used for face display as a means of communication between humans and robots. In the face display, a more natural facial expression can be expressed. It is also easy to change the complexion as flushed. Since it is easy to match the facial expression of each person in the face, it can be expected to be used for the face of a face-to-face guidance robot and the facial expression of a care robot. As other applications, it can be installed on a curved body and used as an information display / advertisement display device.
