A method of manufacturing a display device capable of maintaining a cell gap constant is provided. The apparatus may determine a distortion region based on warped pixels in a synthesized image of an intermediate view; and define a surface area of the distortion region as a distortion function of the synthesized image. At least one sensor extends at least partly into the honeycomb body. The play list contains a list of script items, where each script item contains motion data for operating the motion device to perform a desired movement sequence. The heat-transfer chamber is a part of the cooling circuit of the fuel cell unit.
