LIQUID CRYSTAL DRIVING DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, AND LIQUID CRYSTAL DRIVING METHOD

摘要

A liquid crystal controller (20) includes a memory (21) for storing a plurality of gray scale conversion tables (21b) each having a different gray scale changing degree; a selecting section (22a) for selecting, from the plurality of gray scale conversion tables (21b), a gray scale conversion table to be referred to; and a conversion section (22b) for converting input gray scale data with reference to the gray scale conversion table (21b) selected. A selection condition in the selecting section (22a) is set such that: (i) as a vertical frequency of a liquid crystal display becomes higher and a liquid crystal temperature becomes lower, the gray scale conversion table of a higher gray scale changing degree is selected; and (ii) in regard to at least one of the gray scale conversion tables (21b), as the vertical frequency becomes higher, a liquid crystal temperature range in which the at least one gray scale conversion table (21b) is to be selected becomes wider. As a result, gray scale conversion that is more suitable for an overshoot drive is implemented.
