Abstract
A liquid crystal display including a liquid-crystal display unit having a matrix of multiple pixels. A field of a digital input video signal to be supplied to the liquid-crystal display unit is divided into a plurality of subfields. The voltage of the digital video signal is adjusted per subfield to compensate for change in gamma characteristics of the liquid-crystal display unit. Instead of the voltage, the period of at least one subfield of the video signal can be adjusted for compensating for change in the gamma characteristics of the liquid-crystal display unit.

A liquid crystal display including a liquid-crystal display unit having a matrix of multiple pixels comprising:
- a detector to detect a temperature of the liquid-crystal display unit;
- and
- an adjuster to adjust the temperature of the liquid-crystal display unit to a given temperature in response to the detected temperature to compensate for a temperature-dependent change in gamma characteristics of the liquid-crystal display unit.
A color liquid crystal display including spatial light modulators for colors red, green and blue comprising:
- a detector to detect a temperature of each spatial light modulator, and
- an adjuster to adjust the temperature of each spatial light modulator to a given temperature or within a given temperature range in response to the detected temperature to compensate for a temperature-dependent change in gamma characteristics of the spatial light modulators.

A method of driving a liquid crystal display including a liquid-crystal display unit having a matrix of multiple pixels comprising the steps of:
- detecting a temperature of the liquid-crystal display unit;
- and
- adjusting the temperature of the liquid-crystal display unit to a given temperature in response to the detected temperature to compensate for a temperature-dependent change in gamma characteristics of the liquid-crystal display unit.
A method of driving a color liquid crystal display including spatial light modulators for colors red, green and blue comprising the steps of:
- detecting a temperature of each spatial light modulator;
- and
- adjusting the temperature of each spatial light modulator to a given temperature or within a given temperature range in response to the detected temperature to compensate for a temperature-dependent change in gamma characteristics of the spatial light modulators.
