摘要:
A video display system is disclosed which has a video signal source for supplying the video signal of odd fields and even fields which are interlaced with each other, a first set of display cells for the odd fields, a second set of display for the even fields and arranged alternately with the first set of display cells in an interlaced fashion, a first circuit for supplying the video signal of the odd fields to the first set of display cells during the odd fields, and a second circuit for supplying the video signal of the even fields to the second set of display cells during the even fields. In this case, the first circuit includes a latching circuit for latching the video signal of the odd fields and supplying the latched signal to the first set of display cells during the even fields, and the second circuit includes a latching circuit for latching the video signal of the even fields and supplying the latched signal to the second set of display cells during the odd fields.
