    摘要： An object of the present invention is to provide a touch panel that is hardly affected by pyroelectric noise due to temperature changes.
    As a means for achieving the above object, the present invention provides a touch panel 2. The touch panel 2 comprises a first pyroelectric material 26 and a second pyroelectric material 27, and is capable of detecting press pressure applied to the first pyroelectric material 26 and/or the second pyroelectric material 27. The upper surface of the first pyroelectric material 26 and the lower surface of the second pyroelectric material 27 are surfaces on which a positive charge is generated when the temperature increases, and a negative charge is generated when the temperature decreases. The lower surface of the first pyroelectric material 26 and the upper surface of the second pyroelectric material 27 are surfaces on which a negative charge is generated when the temperature increases, and a positive charge is generated when the temperature decreases. An electrode disposed on the first surface of the first pyroelectric material 26 and an electrode disposed on the first surface of the second pyroelectric material 27 are electrically connected to each other, and an electrode disposed on the second surface of the first pyroelectric material 26 and an electrode disposed on the second surface of the second pyroelectric material 27 are electrically connected to each other.

    摘要： An object of the present invention is to provide a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film that can significantly reduce, when used as an optical film, the deterioration of the quality of video or still images formed by display elements.
    The present invention provides a polarized vinylidene fluoride/tetrafluoroethylene copolymer resin film having 2,000 or fewer spot defects per m 2 , the number of spot defects being measured by a defect measurement method;
    the method using an surface inspection system in which a CCD camera is placed so as to detect defects at an angle of 45 degrees relative to an LED source, defects of the film are read within a rectangular range of 300 mm in a width direction (the direction perpendicular to the scanning direction), and 150 mm in a machine direction (the scanning direction), while the film is scanned under the camera at a rate of 20 m/min;
    wherein first, defects having a bright area of 1.5 mm 2 or less and a dark area of 1.4 mm 2 or less are selected; and
    next, in order to remove defects resulting from causes other than a corona treatment contained in these defects, a circumscribed rectangle of defect is set so as to have two sides along the scanning direction, and the number of only defects that have a circumscribed width of 2.88 mm or less, a circumscribed length of 2.3 mm or less, an aspect ratio of -39 to +27, an occupancy area ratio in the circumscribing rectangle of 4,000 to 6,950, and an area ratio of -3,100 to +5,200, is automatically counted as spot defects by the surface inspection system.

    摘要翻译： 本发明的目的是提供一种偏光偏氟乙烯/四氟乙烯共聚物树脂薄膜，当用作光学薄膜时，可以显着降低由显示元件形成的视频或静止图像的质量的劣化。 本发明提供一种偏光偏二氟乙烯/四氟乙烯共聚物树脂膜，其每平方米具有2000个以下的斑点缺陷，通过缺陷测量方法测量的斑点缺陷数; 使用其中放置CCD照相机以便相对于LED源以45度的角度检测缺陷的表面检查系统的方法，在宽度方向上的300mm的矩形范围内读取膜的缺陷（ 垂直于扫描方向的方向），并且在机器方向（扫描方向）上为150mm，同时以20m / min的速率在相机下扫描胶片; 其中，首先选择亮区域为1.5mm 2以下，暗区域为1.4mm 2以下的缺陷; 接下来，为了除去由这些缺陷中包含的电晕处理以外的原因引起的缺陷，将外接的缺陷矩形设定为沿着扫描方向具有两侧，并且仅具有外接宽度的缺陷的数量 2.88mm以下，外接长度为2.3mm以下，纵横比为-39〜+27，外接矩形的占有面积比为4,000〜6,950，面积比为3100〜+ 52,200。 由表面检查系统自动计算为斑点缺陷。
