DRIVING METHOD OF LIQUID CRYSTAL DISPLAY ELEMENT AND DRIVING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To drive liquid crystal display elements, that utilize high speed responding liquid crystals, with high speed switching. SOLUTION: L row electrodes are batch selected in plurality. The selection voltage is set to a voltage level of either +Vror -Vr. Column vector elements of a K-th orthogonal matrix (where K is a power of two and is equal to or greater than L) having +Vrand -Vras elements are made corresponding to the selection voltages to be applied to respective row electrodes. On the other hand, a voltage having a level corresponding to the total sum of exclusive OR of corresponding elements of a data vector and a selection voltage vector is applied to column electrodes.
