Patent ID: 7333098

Claim:
A display apparatus comprising: a panel including a plurality of gate lines extending along rows, a plurality of signal lines extending along columns, a plurality of pixels arranged in a matrix at intersecting points at which said gate lines and said signal lines intersect with each other, and a plurality of image lines separated into a plurality of systems for supplying an image signal; a vertical driving circuit connected to said gate lines for successively selecting the rows of said pixels; a plurality of sampling switches disposed for connecting said signal lines to said image lines; and a horizontal driving circuit operable in response to a clock signal for successively generating sampling pulses to successively drive said sampling switches so that the image signal is successively written into the pixels of the selected row; said horizontal driving circuit applying two pulses including a precharging pulse and a sampling pulse to each of said sampling switches such that the corresponding signal line is precharged with the image signal in response to the precharging pulse and then the image signal is sampled to the signal line in response to the sampling pulse; said image lines being connected such that, when the sampling pulse of two pulses applied to a first one of said sampling switches and the precharging pulse of the two pulses applied to a second one of said sampling switches are in a temporarily overlapping relationship with each other, image lines of a first system are connected to the first sampling switch and image lines of a second system are connected to the second sampling switch thereby to prevent interference of the image signal between the first and second sampling switches due to overlapping of the precharging and sampling pulses.
