Display device with matrix-arranged pixels having reduced number of vertical signal lines

A display device comprising a display panel and a driving circuit therefor, said display panel including a plurality of signal lines extending in a vertical direction, a plurality of scanning lines extending in a horizontal direction, and display elements disposed as pixels at respective intersections of a matrix formed by said signal lines and said scanning lines, said signal lines, said scanning lines and said display elements being disposed on a substrate, in which said driving circuit includes a horizontal scanning circuit for dividing the pixels in one row arranged in the horizontal direction into a plurality of groups, for sampling pixel information for the plurality of groups from a video signal for one row time-serially sent and containing two-dimensional image information, and for delivering time-serially the pixel information for the plurality of groups to drive said signal lines during a period of time when the video signal for one row is sent, wherein the total number of said display elements as pixels arranged in one row in the horizontal direction is larger than the total number of said signal lines, and each of said scanning lines is operatively connected to at least two pixels adjacent to each other of one group in the one row and the at least two adjacent pixels of the one group are operatively connected to different signal lines, whereby each of the at least two adjacent pixels of the one group is driven by a different combination of one of said scanning lines and a different respective one of said different signal lines.

A display device comprising a display panel including display elements disposed as pixels at intersections of a predetermined even number 2N of vertical columns with N being an integer and horizontal rows of a matrix on a substrate, left side and right side vertically-scanning sections being provided on a left side and a right side horizontally of said matrix on said substrate, and a horizontal scanning section being provided vertically adjacent to said matrix on said substrate, a predetermined number N of signal lines being provided along said even number 2N of vertical columns wherein all left side signal lines are in common with all right side signal lines, respectively, said vertical columns being numbered sequentially from left to right horizontally of said matrix as the 1st to the 2Nth vertical columns, respectively, gate controllable switching means having respective control gates disposed along each of said vertical columns in accordance with intersections with said matrix with each of said switching means being adapted for operatively connecting the respective display elements to the respective vertical signal line portion along each column, left side and right side vertical scanning lines being provided along said matrix rows respectively for vertically scanning said switching means, said left side vertical scanning lines being connected to control gates of said switching means disposed in accordance with the matrix intersections of the respective rows and said 1st to Nth columns, said right side vertical scanning lines being connected to control gates of said switching means disposed in accordance with the matrix intersections of the respective rows and said (N+1)th to the 2Nth columns, said left side and right side vertically-scanning sections, respectively, being connected to said left side and right side vertical scanning lines for selectively enabling said lines to enable said switching means connected thereto, and said horizontal scanning section having N output terminals connected to said N number of signal lines for applying video signals therethrough to said display elements through said enabled switching means, wherein a total number N of connection lines connecting said output terminals to said signal lines is one half of the total number 2N of said vertical signal lines.
