この実施の形態のフレキシブル光学測定用治具１は、フレキシブル光学表示パネル２の製造工程において、フレキシブル光学表示パネル２の表示部の輝度、色度、セルギャップ等の光学特性を測定するものであり、任意な曲率を有するフレキシブル光学表示パネル２を保持することが可能な所定の曲率をもった保持部材１０と、保持部材１０を移動させるための保持部材１０と同一の曲率を有し、且つ保持部材１０を移動させるための台部材２０とからなり、台部材２０により保持部材１０が移動可能であり、フレキシブル光学表示パネル２のいずれの測定においても、測定位置を法線方向から測定可能にする。 The flexible optical measurement jig 1 of this embodiment measures optical characteristics such as luminance, chromaticity, and cell gap of the display section of the flexible optical display panel 2 in the manufacturing process of the flexible optical display panel 2. A holding member 10 having a predetermined curvature capable of holding the flexible optical display panel 2 having an arbitrary curvature, and a holding member 10 having the same curvature as the holding member 10 for moving the holding member 10 The holding member 10 can be moved by the base member 20, and the measurement position can be measured from the normal direction in any measurement of the flexible optical display panel 2. .
保持部材１０は、所定の曲率の表面を有する板状であり、フレキシブル光学表示パネル２を所定の曲率の表面に保持可能である保持部１１と、保持部１１に形成された光学測定するための開口部１２と、保持部１１の両端に台部材２０に移動可能にするスライド部１３とを有する。 The holding member 10 is a plate having a surface with a predetermined curvature, a holding unit 11 capable of holding the flexible optical display panel 2 on the surface with a predetermined curvature, and optical measurement formed on the holding unit 11. It has the opening part 12 and the slide part 13 which makes the base member 20 movable to the both ends of the holding | maintenance part 11.
保持部材１０は、厚さｔ、曲率半径Ｒを有し、保持部１１の曲率半径Ｒ側の凸表面にフレキシブル光学表示パネル２を固定する。フレキシブル光学表示パネル２の固定方法に関しては、フレキシブル光学表示パネル２の表示領域に影響を与えず、取扱い時にフレキシブル光学表示パネル２と保持部材１０の位置がずれないように固定する。 The holding member 10 has a thickness t and a curvature radius R, and fixes the flexible optical display panel 2 to the convex surface of the holding portion 11 on the curvature radius R side. Regarding the fixing method of the flexible optical display panel 2, the flexible optical display panel 2 is fixed so that the display area of the flexible optical display panel 2 is not affected and the positions of the flexible optical display panel 2 and the holding member 10 are not shifted during handling.
例えば、保持部材１０とフレキシブル光学表示パネル２にネジ穴を設けて締付手段により締付固定する方法やフレキシブル光学表示パネル２の外周部、もしくは曲げ方向の端部のみを金具やプラスチック板で固定する方法、または簡易に強力粘着テープで固定する方法などがある。この実施の形態では、強力粘着テープ１９により固定しているが、この発明における固定方法に関しては、これに限定されない。 For example, a screw hole is provided in the holding member 10 and the flexible optical display panel 2 and tightened and fixed by a tightening means, or only the outer peripheral portion or the bending direction end of the flexible optical display panel 2 is fixed with a metal fitting or a plastic plate. Or a simple fixing method using a strong adhesive tape. In this embodiment, it is fixed by the strong adhesive tape 19, but the fixing method in the present invention is not limited to this.
保持部材１０は、保持部１１に１ないし複数の開口部１２を有し、この開口部１２の大きさ及び数は、フレキシブル光学表示パネル２の測定スポット径や測定箇所に準じるため、任意とする。 The holding member 10 has one or a plurality of openings 12 in the holding portion 11, and the size and number of the openings 12 are arbitrary because they conform to the measurement spot diameter and measurement location of the flexible optical display panel 2. .
この台部材２０は、置くことを可能にする台部２１と、台部に形成された光学測定するための開口部２２と、台部２１に設けられた保持部材１０を移動可能にするガイド部２３とを有する。ガイド部２３には、保持部材１０の支持部１３を移動可能にするため保持部材１０と同一の曲率半径Ｒを持ち且つ保持部材１０のスライド部１３を可動するためのガイド溝部２４が形成されている。 The pedestal member 20 includes a pedestal portion 21 that can be placed, an opening portion 22 for optical measurement formed on the pedestal portion, and a guide portion that allows the holding member 10 provided on the pedestal portion 21 to move. 23. The guide portion 23 is formed with a guide groove portion 24 having the same radius of curvature R as the holding member 10 and allowing the slide portion 13 of the holding member 10 to move so that the support portion 13 of the holding member 10 can be moved. Yes.
台部材２０のガイド部２３は、保持部材１０の移動量を表示する目盛２５と、フレキシブル光学表示パネル２の測定位置を表示する測定印２６とを有する。目盛２５及び測定印２６は、ガイド部２３のガイド溝部２４に形成されているために保持部材１０は透明樹脂で成形される。また、目盛り２５と測定印２６をガイド部２３の側面にガイド溝部２４に沿って形成すれば、保持部材１０も透明樹脂に限定されない。このようにして、目盛２５及び測定印２６を外部から容易に目視可能になっている。 The guide portion 23 of the base member 20 includes a scale 25 that displays the amount of movement of the holding member 10 and a measurement mark 26 that displays the measurement position of the flexible optical display panel 2. Since the scale 25 and the measurement mark 26 are formed in the guide groove portion 24 of the guide portion 23, the holding member 10 is formed of a transparent resin. Further, if the scale 25 and the measurement mark 26 are formed on the side surface of the guide portion 23 along the guide groove portion 24, the holding member 10 is not limited to the transparent resin. In this way, the scale 25 and the measurement mark 26 can be easily seen from the outside.
また、台部材２０は、フレキシブル光学表示パネル２を測定位置で固定させるために保持部材１０を締付ける締付部材２７を有する。締付部材２７は、締付ネジで形成され、図５（ａ）に示すように、ガイド部２３の上端からガイド溝部２４に位置する保持部材１０の表面側端面を締付けて固定する構造でも、図５（ｂ）に示すように、ガイド部２３の外側からガイド溝部２４に位置する保持部材１０の厚さ側端面を締付けて固定する構造でもよい。 Further, the base member 20 has a tightening member 27 for tightening the holding member 10 in order to fix the flexible optical display panel 2 at the measurement position. The tightening member 27 is formed by a tightening screw, and as shown in FIG. 5A, a structure in which the surface side end surface of the holding member 10 located in the guide groove portion 24 from the upper end of the guide portion 23 is fastened and fixed, As shown in FIG. 5B, a structure may be employed in which the thickness-side end surface of the holding member 10 positioned in the guide groove portion 24 is tightened and fixed from the outside of the guide portion 23.
台部材２０は、保持部材１０の大きさによってある程度決まるが、必ずしも保持部材１０の大きさに比例して大きく成形する必要はない。台部材２０には、保持部材１０を台部材２０に固定する締付部材２７を有しており、フレキシブル光学表示パネル２の測定位置で締付部材２７を締めることによって十分測定可能である。 Although the base member 20 is determined to some extent by the size of the holding member 10, it is not always necessary to mold the base member 20 in proportion to the size of the holding member 10. The base member 20 includes a fastening member 27 that fixes the holding member 10 to the base member 20, and sufficient measurement is possible by fastening the fastening member 27 at the measurement position of the flexible optical display panel 2.
測定印２６はガイド溝部２４の高さＤ１の最も低い位置Ｄ２であり、さらに曲面半径Ｒ上に一定の長さごとに印しをつけた目盛２５を有する。測定印２６とフレキシブル光学表示パネル２の測定したい箇所を一致させ、且つ保持部材１０を移動させることで、いずれの測定においても、測定位置を法線方向から測定可能にする。 The measurement mark 26 is the lowest position D2 of the height D1 of the guide groove 24, and further has a scale 25 that is marked on the curved surface radius R for every certain length. The measurement position can be measured from the normal direction in any measurement by matching the measurement mark 26 and the position to be measured on the flexible optical display panel 2 and moving the holding member 10.
また、目盛２５は、保持部材１０の移動量を表示し、目盛２５に基づいて保持部材１０を移動し、フレキシブル光学表示パネル２の測定位置を変化させることができる。この目盛２５を利用することで、繰り返し測定の再現性が向上する。 The scale 25 can display the movement amount of the holding member 10, move the holding member 10 based on the scale 25, and change the measurement position of the flexible optical display panel 2. By using this scale 25, the reproducibility of repeated measurement is improved.
（フレキシブル光学測定用治具を用いた光学測定）
次に、フレキシブル光学測定用治具を用いた光学測定を、図６に基づいて説明する。図６はフレキシブル光学測定用治具と光学測定装置における測定位置関係を示す図である。
(Optical measurement using a flexible optical measurement jig)
Next, optical measurement using the flexible optical measurement jig will be described with reference to FIG. FIG. 6 is a diagram showing a measurement position relationship between the flexible optical measurement jig and the optical measurement apparatus.
この光学測定装置５０は、発光部５１と受光部５２を備え、フレキシブル光学表示パネル２の製造工程において、フレキシブル光学表示パネル２の表示部の輝度、色度等の物理量を測定することで、表示部の光学特性を測定し、この光学特性の測定は発光部５１からの光をフレキシブル光学表示パネル２の表示部に照射し、受光部５２によって受光することで行う。 The optical measuring device 50 includes a light emitting unit 51 and a light receiving unit 52, and displays physical quantities such as luminance and chromaticity of the display unit of the flexible optical display panel 2 in the manufacturing process of the flexible optical display panel 2. The optical characteristics are measured by irradiating the display unit of the flexible optical display panel 2 with light from the light emitting unit 51 and receiving the light by the light receiving unit 52.
この光学測定装置５０を用いた測定時に、フレキシブル光学測定用治具１を光学測定装置５０の光線Ｓ上に、対向するガイド部２３の測定印２６を結ぶ線Ｋとフレキシブル光学表示パネル２の測定したい箇所が一致するようにセットする。この光学測定装置５０の光線Ｓと線Ｋの交点上にあるフレキシブル光学表示パネル２の位置は、フレキシブル光学表示パネル２の測定箇所を法線方向から測定した位置にあたる。この光学特性の測定は、フレキシブル光学測定用治具１の保持部材１０が台部材２０により移動することで、いずれの測定においても、測定位置を法線方向から測定可能にする。このフレキシブル光学表示パネル２の移動は、目盛２５に基づいて保持部材１０を移動し、フレキシブル光学表示パネル２の測定位置を変化させる。 At the time of measurement using the optical measurement device 50, the flexible optical measurement jig 1 is measured on the light S of the optical measurement device 50 and the line K connecting the measurement mark 26 of the guide portion 23 facing the flexible optical display panel 2. Set the parts you want to match. The position of the flexible optical display panel 2 on the intersection of the light beam S and the line K of the optical measuring device 50 corresponds to the position measured from the normal direction of the flexible optical display panel 2. The measurement of the optical characteristics enables the measurement position to be measured from the normal direction in any measurement by moving the holding member 10 of the flexible optical measurement jig 1 by the base member 20. The movement of the flexible optical display panel 2 moves the holding member 10 based on the scale 25 and changes the measurement position of the flexible optical display panel 2.
図７の光学測定の概念図に示すように、この実施の形態では、フレキシブル光学測定用治具１を用いて光学測定装置５０により任意な曲率を有するフレキシブル光学表示パネル２の光学測定を行う。この光学測定装置５０では、フレキシブル光学表示パネル２の測定ポイントＡ１の法線方向を光学測定装置５０の光線Ｓと一致させて測定を行い（図７（ａ））、測定ポイントＡ１でのフレキシブル光学表示パネル２の厚さはＤ１で、光線Ｓと一致する法線方向での厚さである。そして、このフレキシブル光学表示パネル２の測定位置を変えるために、フレキシブル光学測定用治具１を用いてフレキシブル光学表示パネル２を移動して測定ポイントＡ２で測定すると（図７（ｂ））、この測定ポイントＡ２でもフレキシブル光学表示パネル２の法線方向と光学測定装置５０の光線Ｓは一致しており、フレキシブル光学表示パネル２の厚さはＤ１で、法線方向での厚さである。このように、フレキシブル光学表示パネル２の測定位置を変化させるいずれの測定においても測定ポイントでのフレキシブル光学表示パネル２の厚さは常にＤ１の法線方向での厚さであり、フレキシブル光学表示パネル２の測定箇所を法線方向から評価できる。 As shown in the conceptual diagram of optical measurement in FIG. 7, in this embodiment, optical measurement of the flexible optical display panel 2 having an arbitrary curvature is performed by the optical measurement device 50 using the flexible optical measurement jig 1. In this optical measuring device 50, the normal direction of the measurement point A1 of the flexible optical display panel 2 is made to coincide with the light beam S of the optical measuring device 50 (FIG. 7A), and the flexible optical at the measurement point A1 is performed. The thickness of the display panel 2 is D1, which is the thickness in the normal direction that coincides with the light ray S. Then, in order to change the measurement position of the flexible optical display panel 2, the flexible optical display panel 2 is moved using the flexible optical measurement jig 1 and measured at the measurement point A2 (FIG. 7B). Even at the measurement point A2, the normal direction of the flexible optical display panel 2 and the light beam S of the optical measuring device 50 coincide with each other, and the thickness of the flexible optical display panel 2 is D1, which is the thickness in the normal direction. Thus, in any measurement in which the measurement position of the flexible optical display panel 2 is changed, the thickness of the flexible optical display panel 2 at the measurement point is always the thickness in the normal direction of D1, and the flexible optical display panel The two measurement points can be evaluated from the normal direction.
フレキシブル光学測定用治具１を用いない比較例では、フレキシブル光学表示パネル２の測定ポイントＡ２の法線方向を光学測定装置５０の光線Ｓと一致させずに測定を行うと（図７（ｃ））、測定ポイントＡ２でのフレキシブル光学表示パネル２の厚さはＤ１より長いＤ２となる。このように、比較例では、フレキシブル光学測定用治具１を用いないで測定を行うと、法線方向からズレた厚さで測定することになる。 In the comparative example that does not use the flexible optical measurement jig 1, measurement is performed without making the normal direction of the measurement point A 2 of the flexible optical display panel 2 coincide with the light beam S of the optical measurement device 50 (FIG. 7C). ), The thickness of the flexible optical display panel 2 at the measurement point A2 is D2 longer than D1. As described above, in the comparative example, when the measurement is performed without using the flexible optical measurement jig 1, the thickness is measured with a deviation from the normal direction.
このように、この実施の形態では、任意な曲率を有するフレキシブル光学表示パネル２の測定位置を変化させるいずれの測定においても、フレキシブル光学表示パネル２の法線方向から測定することになり、測定の焦点位置が異なり、測定スポット径が変化することや測定面に対して斜めから評価することがなく、正確な測定値が得られ、精度良くフレキシブル光学表示パネル２を評価できる。 As described above, in this embodiment, in any measurement in which the measurement position of the flexible optical display panel 2 having an arbitrary curvature is changed, the measurement is performed from the normal direction of the flexible optical display panel 2. The focal position is different, the measurement spot diameter is not changed, and the measurement surface is not obliquely evaluated, so that an accurate measurement value can be obtained and the flexible optical display panel 2 can be evaluated with high accuracy.
例えば、電圧‐透過率測定では、フレキシブル光学表示パネル２に所定の電圧を印加させ、その時の輝度を測定する。フレキシブル光学表示パネル２に対して法線方向から測定しないと、フレキシブル光学表示パネル２を通る距離が長くなり、正確な輝度が得られない。 For example, in the voltage-transmittance measurement, a predetermined voltage is applied to the flexible optical display panel 2 and the luminance at that time is measured. Unless the measurement is performed from the normal direction to the flexible optical display panel 2, the distance passing through the flexible optical display panel 2 becomes long, and accurate luminance cannot be obtained.
また、例えば、セルギャップ測定では、ある所定の直線偏光をフレキシブル光学表示パネル２に当て、位相がどのように変わったかでセルのギャップを測定する。フレキシブル光学表示パネル２に対して法線方向から測定しないと、フレキシブル光学表示パネル２を通る距離が長くなり、正確な位相の変化を測定できない。 Further, for example, in the cell gap measurement, a predetermined linearly polarized light is applied to the flexible optical display panel 2, and the cell gap is measured according to how the phase has changed. Unless the measurement is performed from the normal direction to the flexible optical display panel 2, the distance passing through the flexible optical display panel 2 becomes long, and an accurate change in phase cannot be measured.
また、フレキシブル光学測定用治具１は、保持部材１０は一定の曲率を持っているため、フレキシブル光学表示パネル２を保持部材１０に沿わすだけで均一に曲げることが可能である。また、この保持部材１０は、耐熱性や耐湿性の高い材質を用いれば、フレキシブル光学表示パネル２を固定したまま信頼性試験に投入することができ、容易に曲面フレキシブル光学表示パネル２の特性を評価することができる。さらに、フレキシブル光学測定用治具１は、縦にも横にも設置可能であり、様々な光学測定装置に取り付けることができる。 In addition, since the holding member 10 has a certain curvature, the flexible optical measuring jig 1 can be bent evenly along the holding member 10. Further, if the holding member 10 is made of a material having high heat resistance and moisture resistance, the flexible optical display panel 2 can be put into a reliability test while being fixed, and the characteristics of the curved flexible optical display panel 2 can be easily obtained. Can be evaluated. Furthermore, the flexible optical measurement jig 1 can be installed vertically or horizontally, and can be attached to various optical measurement devices.
この発明は、任意な曲率を有するフレキシブル光学表示パネルの光学特性を測定することができるフレキシブル光学測定用治具に適用可能であり、任意な曲率を有するフレキシブル光学表示パネルのいずれの測定位置においても、常に測定位置を法線方向から測定できる。 The present invention is applicable to a flexible optical measurement jig capable of measuring the optical characteristics of a flexible optical display panel having an arbitrary curvature, and can be applied to any measurement position of the flexible optical display panel having an arbitrary curvature. The measurement position can always be measured from the normal direction.
