  • Patent number: 10726776
    Abstract: A pixel-by-pixel calibration method is provided. Multiple sample cabinets are selected from to-be-calibrated cabinets to form a small screen with the sample cabinets, image acquisitions are performed on the small screen and luminance-chrominance mean deviation ratios are calculated. The sample cabinets are placed at fulcrum positions of a large screen to be calibrated, and the other remaining cabinets are placed at other positions. Full-screen original luminance-chrominance values are obtained by image acquisition on the large screen, original luminance-chrominance values of the sample cabinets are adjusted by the luminance-chrominance mean deviation ratios, and luminance-chrominance distribution fitting surfaces are generated by adjusted full-screen original luminance-chrominance values to amend the full-screen original luminance-chrominance values.

  • Publication number: 20130075053
    Abstract: The invention provides a heat retention barrel and a vertical heat treatment apparatus provided with the heat retention barrel. The heat retention barrel is used for supporting the wafer boat and comprises a barrel body and a barrel base. The external rim of the bottom of the barrel body is located within the upper surface of the barrel base. The pollution of the particles in the heat retention barrel to the reaction chamber of the vertical heat treatment apparatus can be eliminated through the portion of the upper surface of the barrel base outside the external rim. The selection of the materials for the heat retention barrel can increase the heat retention and heat insulation effects as well as the use safety.
