Title: Driving method of liquid crystal element and the like and display device
Inventor: ITO AKIHIKO
IPC: G02F1/133
Filed: 1994-12-28
Abstract: PURPOSE: To lessen unequal display, to improve display quality and to reduce electric power consumption by impressing voltages of the (k) bit-components within (i) bits of display data in one selection pattern period. CONSTITUTION: Four lines each are simultaneously selected and the two selected patterns are impressed on scanning electrodes in one selection period, by which display is made in eight gradations. In such a case, the display data is 3 bits and is weighted to signal electrode waveforms by voltages and pulse widths according to the weighting of each bit. The most significant bit is defined as (a), the next bit as (b) and the least significant bit as (c). The voltages corresponding to the weighting of the respective bits are impressed in order of Ca in, for example, 1/2H of the first half and ac in 1/2H of the second half when the voltage impression is viewed with respect to a selection period. The voltages corresponding to the weighting of the respective bits are impressed in order of ba in the first half and ab in the second half.  Thus, the voltages corresponding to the two bits among the three bits of the display are impressed at equal intervals in the period of one selection pattern.
