Abstract:
A liquid crystal display apparatus, comprising:an active matrix type liquid crystal panel in which potentials of respective data lines are applied to respective display electrodes of a selected display line via respective switching devices of said selected display line, said selected display line corresponding to a selected one of scanning lines connected to control inputs of said switching devices; a data driver for applying said potentials to said respective data lines and renewing said potentials at every horizontal cycle; a scanning driver for providing scanning pulses to said respective scanning lines in line-sequence; and a control circuit for causing a timing of a rear edge of a scanning pulse provided to a predetermined scanning line to coincide with a time when said potentials of said data lines are in transition from last values to next values, such that latched potentials of said display electrodes corresponding to said predetermined scanning line, having values corresponding to said potentials of said data line during said transition, are values higher than one of two scanning lines adjacent to said predetermined scanning line and lower than the other of the two scanning lines adjacent to said predetermined scanning line; wherein said predetermined scanning line is one corresponding to an addition of picture line to or a reduction of picture line from a picture to be displayed, in order to compensate for a difference between a number of said scanning lines and that of picture lines of said picture to be displayed.
