A chromaticity correction device corrects chromaticity of a video signal displayed on a display panel of a display device to correspond to a change in a luminance value of the display panel. The heat exchanging units are arranged to be spaced apart from one another along a first direction. The arrangement is designed to preserve orientation information and allow for unobscured imaging of the sample. Sequences of one or more of these packets create unique encoding \u201ccommands\u201d that can be sent over any network and easily decoded with either software or hardware. The process of adjusting the transmit power may take into account a functional relationship between the transmitted power and properties of the channel. The resin material is received in the cavity forming part of the lower mold after the resin material is pressurized and dispersed in a sealing resin supply apparatus.
