Patent ID: 7042435

Claim:
A liquid crystal display apparatus comprising: a liquid crystal display which comprises a plurality of pixels arranged in a matrix; a driving circuit which comprises a scanning electrode driver and a signal electrode driver and which drives the liquid crystal display by a simple matrix driving method; and a controller which controls the driving circuit in such a way that waveforms of pulses output from the scanning electrode driver change depending on a circumstantial temperature of the liquid crystal display; wherein: the controller controls the driving circuit to heighten a voltage of a selection pulse, which is output from the scanning electrode driver to determine a final state of the liquid crystal, with a rise in circumstantial temperature within a specified temperature range and to lower the voltage of the selection pulse with a fall in circumstantial temperature within the temperature range; the scanning electrode driver outputs a chain of driving pulses comprising different kinds of pulses; and the controller controls the driving circuit in such a way that within a specified temperature range, a total length of the chain of driving pulses changes depending on the circumstantial temperature while a ratio of the widths of the pulses to one another is constant.
