Abstract
A liquid crystal television comprises providing two multivibrators different in time constant with a vertical synchronizing pulse inputted as a trigger signal, providing a detection circuit for generating a field detection pulse on output pulses of the multivibrators and a horizontal synchronizing pulse only at the time of odd field or even field, driving an odd gate and an even gate according to the detection pulse, thus subjecting a liquid crystal display panel to interlacing drive.
Claims1
In a liquid crystal television interlacing a liquid crystal display panel of matrix drive in an odd field and an even field separately, the improvement comprising two multivibrators different in time constant with a vertical synchronizing pulse inputted as a trigger signal therefor, a detection circuit for generating a field detection pulse only at the time of the odd field or the even field according to output pulses of said multivibrators and a horizontal synchronizing pulse, thus driving an odd gate of said liquid crystal display panel and an even gate according to the field detection pulse.
