MATRIX DRIVING METHOD FOR CURRENT TYPE DISPLAY ELEMENTS AND MATRIX DRIVING DEVICE FOR CURRENT TYPE DISPLAY ELEMENTS

摘要

PROBLEM TO BE SOLVED: To suppress the effects of floating capacities to be generated at the intersection parts of scanning electrodes and signal electrodes. ;SOLUTION: In this device, current type display elements are arranged at the intersection parts of plural scanning electrodes ScE (ScE₁, ScE₂,... ScE_y) and plural signal electrodes SiE (SiE₁, SiE₂, ...SiE_x) in a matrix shape and the device is provided with a precharge means which, at the time of driving the respective current type display elements by supplying a display signal to the signal electrodes SiE while selecting the scanning electrodes ScE, performs precharges as to the capacities of the intersection parts prior to the supplying of the display signal to the signal electrodes SiE.;COPYRIGHT: (C)1999,JPO
