Patent ID: 7427976

Claim:
A liquid crystal display for image display using a liquid crystal display panel, comprising: a write-gray scale level determining section for determining write-gray scale level data for input image data that compensates an optical response characteristic of the liquid crystal display panel, in accordance with, at least, a combination of gray scale level transitions from a previous vertical display period to a current vertical display period; an achievable gray scale level determining section for generating achievable gray scale level data for input image data after a lapse of one vertical display period of the liquid crystal display panel, in accordance with, at least, a combination of gray scale level transitions from one vertical display period to the next; and a temperature detector for detecting a device interior temperature, wherein the achievable gray scale level determining section has a plurality of achievable gray scale level table memories for a plurality of device interior temperatures, each of the plurality of achievable gray scale level table memories stores achievable gray scale level parameters, each representing achievable gray scale brightness after the lapse of one vertical display period of the liquid crystal display panel, obtained from the optical response characteristics of the liquid crystal display panel, the write-gray scale level determining section has a plurality of write-gray scale level table memories for a plurality of device interior temperatures and determines the write-gray scale level data to be supplied to the liquid crystal display panel by referring to one of the plurality of write-gray scale level table memories, and the achievable gray scale level determining section selects, from the plurality of achievable gray scale level table memories, an achievable gray scale level table memory for the detected device interior temperature, and determines the achievable gray scale level data by referring to the selected achievable gray scale level table memory.
