1. A matrix-type color picture display apparatus comprising:
- a plurality of unit displaying picture elements disposed in a two-dimensional array;
said unit displaying picture elements each consisting of one red display element, one blue display element, and two green display elements;
said display elements of each of said unit displaying picture elements being divided into at least two groups, at least one of said groups comprising at least two display elements, to form at least two unit driving picture elements;
a luminous intensity of each of said red, green, and blue display elements being controlled independently in response to respective red, green, and blue drive signals;
said red, green, and blue drive signals being obtained by converting video signal samples into said red, green, and blue drive signals;
said video signal samples being obtained by sampling a video signal at time intervals corresponding to spatial locations of said unit driving picture elements in said two-dimensional array;
wherein said red, green, and blue drive signals are applied to corresponding red, green, and blue display elements of said unit driving picture elements such that drive signals applied to a given unit driving picture element are derived from a video signal sample corresponding to the spatial location of said given unit driving picture element in said two-dimensional array.

Abstract
A system of signal application to color picture elements of a color display apparatus of the matrix-drive type in which a unit displaying picture element is formed of one red, one blue and two green picture elements and drive signals are applied to unit driving picture elements which is formed by dividing each unit displaying picture element into at least two groups of picture elements whereby a color picture display of high resolution and high picture quality is accomplished.
