Abstract
In a color display device color elements (17, 18, 19, 21, 22, 23) are built up with the aid of picture cells (2) from juxtaposed rows of picture cells which are driven by line electrodes (3). The resolving power in the horizontal sense is increased by building up the color elements from picture cells of different rows of picture cells. The period t.sub.1 which is required for driving a color element is split up into sub-periods 1/2t.sub.1 during which period samples of the signal to be displayed (length t.sub.o) are presented to the column electrodes (4). Since notably for LCD-TV there applies that t.sub.1 >t.sub.o, these samples can be presented during a period which is longer than 1/2t.sub.o.
