Liquid crystal apparatus with temperature-dependent pulse manipulation

摘要

Since a fluorescent lamp has a very wide temperature distribution, a large temperature non-uniformity also occurs on a display unit backlighted by the lamp. On the liquid crystal display, the ratio of pulses applied the information and scanning electrodes are controlled in accordance with the temperature change, the overcome the above problem. The ratio of a pulse peak value of a compensation phase part of a scanning selection signal to a pulse peak value of an auxiliary phase part of an information signal may be changed according to a change in temperature.
