  • Patent number: 9524914
    Abstract: A method of manufacturing an organic EL display apparatus including an organic EL panel having light emitting pixels each of which has an organic EL element (OEL) includes: lighting up lighting target pixels set from among the light emitting pixels; causing an imaging device to photograph the organic EL panel and receiving a photographed image from the imaging device; detecting the lighting target pixels using the photographed image; determining whether an undetectable pixel that cannot be detected is included among the lighting target pixels, using a result obtained in the detecting; increasing an amount of luminescence of the undetectable pixel to a detectable amount of luminescence, when it is determined that the undetectable pixel is included; and aligning a relative position of the organic EL display apparatus and the imaging device, using the result obtained in the detecting.

  • Patent number: 9322707
    Abstract: Disclosed is a method for measuring luminance of each of entire pixels two-dimensionally arranged in a light-emitting display panel at regular intervals, using an image sensor in which light receiving elements are two-dimensionally arranged at regular intervals, the method including: providing an optical lens between the light-emitting display panel and the image sensor, and adjusting distances between the light-emitting display panel, the image sensor, and the optical lens by setting intervals of images of the entire pixels to be N times as large as intervals of the light receiving pixels, where N is a natural number, the images being to be formed on a light receiving surface of the image sensor through the optical lens; displaying, on the light-emitting display panel, a display pattern in which predetermined pixels from among the entire pixels produce a luminescence; and measuring the luminance of the predetermined pixels, using the light receiving elements.

  • Patent number: 9209402
    Abstract: A method of manufacturing an EL display device having a light emitting part, in which a plurality of pixels are arrayed, and a thin-film transistor array device to control light emission of the light emitting part, includes a luminance measurement step of obtaining luminance data of pixel, with the light emitting part being lit. The luminance measurement step includes a first luminance measurement step and a second luminance measurement step. In the first luminance measurement step, a first imaging apparatus obtains luminance data by measuring light emission of the each pixel. The first apparatus has a resolution corresponding to that of the pixels of the light emitting part. In the second luminance measurement step after the first step, a second imaging apparatus measures light emission of a plurality of the pixels to correct the luminance data of the each pixel obtained in the first luminance measurement step. The second imaging apparatus is lower in resolution than the first imaging apparatus.
