Patent ID: 7719514

Claim:
A drive apparatus configured to drive a display panel, the drive apparatus comprising: a digital signal driver configured to convert a digital video signal of m bits into a data arrangement, said data arrangement conforming with a display format of the display panel, said display panel having x×y number of pixels arranged in a matrix form at intersecting portions of x number of signal lines disposed in a column direction and y number of gate lines disposed in a row direction, said display format comprising a selectable one of a plurality of display formats, said plurality of display formats comprising: eXtended Graphic Array (XGA), Wide eXtended Graphic Array (WXGA), Super eXtended Graphic Arrayor (SXGA), SXGA+, Ultra eXtended Graphic Array (UXGA), and Full High Definition; at least one pre driver configured to (a) receive the converted digital video signal and (b) convert said signal into parallel analog video signals of p-phase; at least one module configured to develop the analog video signals of the p-phase into analog video signals of x/k-phase, said module configured to deliver the analog video signals of x/k phase to a selected x/k number of video signal supply lines selected from N number of video signal supply lines, wherein N≧x/k, and x/k is determined by the display format of the display panel; and a plurality of signal line selecting switches configured to sequentially select, one by one, at the same timing, desired signal lines from respective groups of the x/k number of signal lines obtained by dividing the x number of signal lines into the k number of the signal lines adjacent in the state where they do not overlap with each other to perform sampling of the analog video signals delivered via the x/k number of video signal supply lines with respect to the selected signal lines, wherein x, y, p, m, k, and N are natural numbers.
