DISPLAY DEVICE DRIVING APPARATUS, DISPLAY DEVICE DRIVING METHOD, AND DISPLAY DEVICE

摘要

In a liquid crystal panel driving apparatus, when the gray scales indicated by an input data are zero to n gray scales, a reference voltage range at a temperature T1 is set to Vmin to Vmax, and a reference voltage range at a temperature T2 lower than the temperature T1 is set to Vmin' to Vmax' (where Vmin' < Vmin and Vmax' > Vmax). At the temperature T1, no gray scale conversions are performed, and the zero to n gray scales are used as display gray scales. At the temperature T2, the gray scale conversions are performed, and i to j gray scales are used as display gray scales (where 0 < i < j < n). Further, gray scale voltages corresponding to the i to j gray scales are set to Vi' to Vj' (where Vmin' < Vi' < Vj' < Vmax'), and at the temperature T2, the ranges of Vmin' to Vi' and Vj' to Vmax' are used in a gray-scale transition emphasizing process. In this way, the moving image display performance at low temperatures can be improved.
