  • Patent number: 10304371
    Abstract: The liquid crystal drive apparatus includes a tone setter that sets drive tones depending on input tones that are tones of an input image, a driver that controls, depending on the drive tones, a voltage applied to each of multiple pixels of a liquid crystal element to a first voltage or a second voltage lower than the first voltage in respective multiple sub-frame periods included in one frame period to cause that pixel to form a tone or controls a drive voltage applied to each of the multiple pixels, and a temperature detector that detects a temperature of or around the liquid crystal element. The tone setter changes, when the input tones include a first tone and a second tone higher than the first tone, the drive tone for the second tone depending on the detected temperature.

The Al-plated steel sheet of the present invention is produced by annealing the Al-plated steel sheet as coiled in a box-anneal furnace for the time and at the temperature indicated in FIG. 5, and alloying of a plated Al and a steel sheet. Further, a method of rapid heating hot-stamping in the present invention is characterized by cutting out a stamping blank of an Al-plated steel sheet, and heating that blank in heating before hot-stamping by an average temperature with a rising rate of 40° C./sec or more and a time of exposure to an environment of 700° C.
